American Medical Library. LECTURES ON THE THEORY AND PRACTICE OF PHYSIC. BY WILLIAM STOKES, M. 1). LECTURER AT THE MEDICAL SCHOOL, PARK STREET, DUELIN *, PHYSICIAN TO THE MEATH HOSPITAL ; &C. &C. FIRST AMERICAN EDITION. P H I L A DELPHU: PUBLISHED BY A. WALDIE, 46 CARPENTER ST. 1837. NOTICE. The present is the first edition of the embodied lectures of Dr. Stokes. They were originally published in the “ London Medical and Surgical Journal,” and were necessarily dispersed over several numbers. Detached lectures have been occasionally reprinted in the different medical periodicals of this country; and their excel- lence has been so manifest, that the particular numbers of the British periodical in which they first appeared have been imported solely on their account. The editor of the “American Medical Library” has consequently thought that he should be rendering a service to his professional brethren by issuing them in the present form. He is not aware of any work in which the topics treated of are displayed in a more attractive, and at the same time a more instructive, manner. The author, from his situation, has every opportunity for confirming or disproving his theoretical considera- tions by the test of practice; he is well informed on every thing that has been done, and is doing, in various countries; and he possesses, withal, powers of discrimination and exposition with which few are favoured. On all these accounts, his lectures will be found peculiarly valuable. ROBLEY DUNGLISON. Philadelphia, June 15th, 1837. St. A CONTENTS. General observations. 1 LECTURE I. LECTURE II.

LECTURES ON THE THEORY AND PRACTICE OF MEDICINE. LECTURE I. GENERAL OBSERVATIONS. Gentlemen:—You may have often heard that the approaches to science are rugged and uninteresting, and some of you have perhaps experienced the truth of the remark. Hence the cus- tom of delivering an introductory lecture, in order to lay before the young mind, when first entering on each path of knowledge, the objects, the results, the attained good, and the hoped-for glory of the pursuit. These are to be displayed with clearness and with truth, yet it is obvious that much of the effect of such a lecture must depend on the nature of the subject and the judgment of the speaker ; and it is well when the exalted nature of the one is attainable by the capabilities of the other. Such a lecture, then, should be an earnest lesson on the objects, the pleasures, and the advantages of that science, of which the course is destined to treat; its history, its true mode of study, its interests, actual state, and future prospects, may all form legitimate subjects, and when thus rightly viewed, an introductory lecture, so far from being a mere ornamental appendage, may become a most important part of the course. With these views let us approach our subject, the theory and practice of medicine. Let us contemplate that study and that pro- fession, which, venerable by all antiquity, yet in itself is “ ever new.” Even in its infancy, when the world was in darkness, was medicine a glorious science when compared with its cotempora- ries, and its first professors were ennobled and exalted by its influ- ence. As their mantles descended through a long line of illustrious successors, we see medicine progressively expanding, and even when the night of barbarism hung gloomily over the earth, we see its genius triumphing over the surrounding darkness, and shining in the east as a beacon to the shipwrecked mind of man ; and I 2 STOKES’S THEORY AND PRACTICE OF MEDICINE. trust that T shall be able to prove to you, that, in our own time, when the human mind has made such astonishing advances, medi- cine has kept pace with her sister sciences, and it is a gratifying reflection to think, that, among the most distinguished promoters of the collateral sciences, physicians have ever held a commanding rank, thus proving themselves foremost in knowledge, as they have ever been in philanthropy, in private and public charity, and in all good will to man. It is scarcely necessary to allude to the title of this course of lectures, further than to remark, that, however different they may be in name, it is yet impossible to draw the line of distinction between the theory and the practice of medicine. If medicine were merely the knowledge of a number of empirical remedies for particular symptoms, given without our enquiring into their mode of action, or any acquaintance with the dependence of one func- tion, or one viscus, on another, of any knowledge, in short, of physi- ology in the healthy or diseased state, then we might have a practice of medicine independent of what is called its theory. But medicine now holds a higher place, and much of its improvement is trace- able to our advances in physiological and pathological science. Thus to treat, or teach, the treatment of a disease, we must know the healthy function of the organ, or organs, the history of deve- lopment, the influence of other organic systems, the changes pro- duced by disease, and, as far as possible, the action of all external or internal agents on the viscera. But this is the theory of me- dicine. For example, let us suppose that we are called either to treat or to teach the treatment of a case of enlarged liver. Let me here remark, that in selecting this case I do not wish you to suppose that I am one of what might be called the hepatic school of medi- cine, in which the existence of almost every organ, except the liver, seems to be forgotten, and of which the creed seems to be, that there is but one viscus, the liver, one source of disease, biliary derangement, and one cure, mercury ; a creed which, though not enforced and defended by the sword, has lost perhaps as much of human life as others whose history is written in letters of blood. But no one can doubt the importance of the organ, and I have taken it to illustrate the connection between the theory and the practice of medicine. You detect an enlarged liver ; you are called to cure the dis- ease :— 1st. You must be aware of the healthy state of the organ, and of its healthy functions, as shown by the volume, sensibility, influ- ence on digestion, and the healthy state of the secretion. You must know all these, as it is by the departure from these conditions that you recognise this disease at all .—But this is the theory of me- dicine. 2dly, You must know the history of its development, because there is a period of life when the natural state of the liver is in a greatly enlarged condition, and this may continue even to adult GENERAL OBSERVATIONS. 3 life, and produce an enlarged liver, not the result of disease but the arrest of development, and the question will arise as to whether the case before you is an example of this, or of recent and actual disease. The whole treatment turns on this.— Yet this is the theory of medicine. 3dly. You must know the influence of other organic systems. An enlarged liver may be produced mechanically by obstructions in the lungs or in the heart; it may be produced from the sympa- thetic irritation of a duodenitis, or be the result of original disease in its own structure. All these circumstances must be known and taken into account. If it be merely obstruction in the venae cavae hepaticae the ordinary treatment will not answer ; if there be duo- denitis we must modify our treatment, and so on. We must know these things ; we must know how to recognise these diseases before we can prescribe or practise successfully. All this is that part of the theory of medicine called pathology, or the physiology of the diseased body. 4thly. You must know the effects of disease on the liver itself. Some of these are removable by art, others are totally incurable. You must know these in order to determine on the probability of their existence. 5thly and lastly. You must know the influence of remedial agents on the liver and the adjacent organs. You must be fami- liar with the effects of stimulation of the mucous surfaces of the stomach and duodenum. Then, indeed, and not till then, will you be qualified to treat the case with judgment and success. The same remarks, I need scarcely add, will be found applicable to the diseases of each viscus in the body. The objects of medicine, gentlemen, are twofold; first, to cure disease, no matter where seated or how produced ; and secondly, to relieve bodily suffering in cases where a cure is impossible. Its great end is to prolong life, and to diminish the bodily evils which result from the infirmities of our nature and other circumstances. Some of you may ask, where then is the distinction between medi- cine and surgery? In truth, there is no distinction in reality, and there should be none in theory. The human constitution is one;— there is no division of it into a medical and surgical domain ; the same laws and the same principles of treatment apply to the cure of a fractured bone and the cicatrisation of an internal ulcer. Unlike the corporations of medicine and surgery, the supposed purely medical and purely surgical parts of the body live in ex- cellent harmony. Here, then, there is no division, no jealousy, no separation of interests. I am by no means prepared to deny that advantages may arise from a practitioner devoting himself to this or that branch of his profession ; but, if he seeks for eminence, he will first educate himself generally. Let him attain extended views of pathological medicine; let him make himself master of the actual state of the science, and then he will find that there is not a single fact or law with which he has become acquainted that will not have its bear- 4 STOKES’S THEORY AND PRACTICE OF MEDICINE. ing on his particular pursuit. It is in the education of medical men that the ruinous effects of the division of the professions of medicine and surgery are most perceived: and I feel convinced that, of the two, the surgical student is the greater sufferer, be- cause his views of pathology are injured. All the great laws in pathology are drawn from the consideration of visceral disease; yet the attention of the surgical student is diverted from this, and directed to what, I will say, can never elevate him in the ranks of science. He is taught anatomy, and what is called surgical disease, but he is kept ignorant, by this wretched system, of the great part of his profession, until he comes to practise, when, if he has a mind fitted for observation, he will find, that for one dislocation there will be hundreds of visceral diseases; and he will discover what was concealed from him during his pupilage, that many, many more die of what are called medical than surgical diseases. During the late war, more men in the British navy died of fever than of all other causes—including the sword. But, I rejoice to say, in Dublin the exclusive system of education is fast wearing away, and one of the many excellences of our national school of medicine is the instruction in general pathology. There are few schools of medicine where now a more enlarged and liberal spirit of education exists. In the study of your profession, gentlemen, let me warn you not to allow yourselves to be misled by the idea that surgery and me- dicine are different in their nature. The mere surgeon, or the mere physician only knows half of his profession. Reckless of human life, he may practise the healing art as a trade, but he never can know it as a science. But, as there are infinitely more cases of what are termed medical than surgical disease, it is plain, that the surgeon, ignorant of medicine, will far exceed the physician igno- rant of surgery, in the extent of his malpractice. I have long observed the ruinous system which has been pursued by teachers, as connected with this subject. The pupil was taught to consider, that if he was a skilful anatomist, if he understood the routine surgery of an hospital, and had carefully studied certain works on surgery, and some obsolete books of pathology, he was thereby prepared, in the language of the schools, to go forth to teach and practise the art and mystery of medicine in general. Now, all this was wrong. You may be profound anatomists and be bad surgeons, and worse physicians; you may have by heart the writings of Pott and Dessault, of Hunter and Thomson, and be totally incapable of treating a simple or complicated fever, or a case of visceral disease. But it is not necessary to say more. Society demands that the old system of a division in education should be abolished; and, ere long, I even trust to see a fusion of the profession, when much of the present evils must cease, when medical men shall have a common centre, from which they will receive a common impulse; when their efforts shall be solely directed to the increase of medical science, and the political and moral exaltation of their profession; and last, yet not least, when the ingenuous pupil shall not be led GENERAL OBSERVATIONS. 5 astray; when he shall not be told by one teacher to despise this, and by another to neglect that part of his profession ; but, having the whole of the noble science of medicine thrown open to him, his mind, unwarped by prejudice, unfettered by fear, shall be permitted to take that right view of his pursuit, that alone can lead him, and assuredly will lead him, to the honours and success which truth bestows on all its votaries. I have said, that the exclusive system of education had singu- larly diminished in Dublin. Indeed, our national school has earned great reputation for general pathology; and, from a long and cordial intercourse with the class of Dublin, I will affirm, that there are few places where we can see such zeal, talent, and thirst for knowledge among the students. As an Irishman, addressing my own countrymen, let me congratulate you on the fame the Dublin School of Medicine and Surgery has now acquired, and is every day acquiring ; and when the strength of Irish talent, aided by the proper working of our unrivaled institutions, is brought into play, may we not anticipate a still more glorious result ? This reflection has often cheered me, that within the last few years there has been a greater stimulus infused into the science and literature of this country. Amid the ungenial influences of political excitement, and the animosities of party, how gladly should we contemplate the advance of what will prove an honour to our national cha- racter, and an advantage to mankind. It is like the growth of the eoral into rocks and fertile islands, though surrounded by the strife and waste of waters. Our scientific societies have multiplied ; our periodical literature, the want of which furnished so fruitful a theme for cavil, has been extended so as to afford a wholesome and vigorous supply in the varied departments of literature and science; and our monthly and quarterly publications are taking their proper place among the ranks of British journals. When we turn to works of a more permanent kind, we also see cause for satisfaction. Many most important works in anatomy, surgical pathology, physiological medicine, and midwifery, have lately issued from the Irish press; and the Irish contributions to the Cyclopaedia of Practical Medicine are allowed on all hands to give to that work no mean portion of its value. There are few more wholesome exercises for the mind, few so necessary and so useful as the comparison of the actual state of any science with its advance and character at a former period; and it is in this, most chiefly, that the value of what is called the history of medicine consists. We study it then, not as a matter of antiquarian research, of learned curiosity, but as the picture of the human mind, now on the right path, now misled by error, yet still struggling onward; as the record of a dear-bought experience, and a beacon to warn us of the rocks and shoals that beset its future progress unto truth. To analyse the actual state of medical science, to show you all that has been done within a little time, to display all old pretensions to the character of a true and thrice noble science, would far exhaust my capabilities and your patience. 6 STOKES’S THEORY AND PRACTICE OF MEDICINE. Let it suffice to contemplate the improvement considered generally, and the means by which that improvement has been attained. It is an error too generally received, that medicine owes all its advances to the researches of modern times. Far be it from me to undervalue these, but I believe that the opinion I have alluded to is wrong, and is perhaps kept alive by our own vanity ; for by a specious deception we often take to ourselves the honours and dis- tinctions of the time we live in. The truth is, that medicine, like many other of the sister sciences, has been long steadily advancing, and the flippant every day remarks that the inductive system (that is, the observation of facts and the embodying of those conclusions that legitimately flow from them) has been only introduced into medicine in our time ; and that our predecessors in medicine put theory first and fact second in their medical philosophy, are “ as false as dicers’ oaths.” Have the authors and teachers who are so fond of decrying the medicine of a former day, at a time when hey are (perhaps innocently) making use of its facts and observa- tions—have they read the writings of the father of medicine? Have they studied that “ aureum opus” so well called from its lustre, its purity, and its surpassing value ? Was Avicenna a mere theorist? Did Morgagni observe no facts, nor truly record them, even at the expense of his medical reputation? Is there no induc- tion in Baglivi? Was Haller unacquainted with the method of experiment and induction ? Or is the discoverer of the circulation of the blood, the good, the great, the injured, but the immortal Harvey, forgotten ? Where do they place Boerhaave ? and shall the name of Sydenham go down with his ashes to oblivion ? The true state of the case is, that medicine, in its present advanced state, only represents the improvement in other branches of human knowledge, all of which are so intimately linked together, that, although their extremes be far removed, there is a point where all are reciprocally cause and effect; so that if we take any one of them, it is easy to show its intimate bearings with, and importance to, all the rest. We have been long advancing in medicine; and though I admit most fully the vast strides which have been made, still I must here declare my firm conviction, that the study of the older authors is too much neglected, and that in them you will find a treasury of knowledge, much of which you may think to be the production of modern times. If the writings of the ancient authors only contained a small portion of the information with which they abound, it would be a sufficient stimulus to their study; to reflect that it is in them, in the medical writings of the ancients, that the germs of the induc- tive philosophy are first to be found. It is, then, in the old regions of medicine that we find the fountains of that mighty river, which, for two thousand years, has fertilised the earth, and made man its lord. Had the progress of man not been retarded by the ignorance which is the child and servant of barbaric despotism, an earlier Newton might have enlightened the earth, an earlier Laplace have measured the heavens, or a Cuvier declared the glories of a past and present GENERAL OBSERVATIONS. 7 creation. The mind of man would have burst its chains, and ages ago have formed that holy alliance with knowledge and her first- born, liberty, which now is its safeguard and its glory. I repeat it, in the writings of Hippocrates you will find the principles of the inductive philosophy. A physician showed Bacon the road to immortality. We find that there is in the mind of man a tendency to reverse the true mode of reasoning, and to seek for a principle before it has observed facts, and this was the cause of the retardation of medicine, as well as of all other sciences. Hence the various schools, from Pythagoras to Cullen or Brown, in our day. But a slow, though sure, revolution was long going forward; and I believe that Cullen and Brown were even behind the actual state of medicine in their time. Physicians turned disgusted from the war of words and doubt, to seek in tangible objects the certainty which these only can produce; in a word, they began to follow the Baconian system more generally. They reverted to the instructions of Hippocrates, and from that period our modern improvement may date. They turned their attention to the examination of those changes which disease produces on the human body, and connected these with the symptoms observed during life. And what has been the result of this? 1st. The accumulation of an enormous number of facts, relative to the changes of organs produced by disease. 2d. The connection of a vast number of these changes with particular symptoms, and hence the advance in diagnosis. 3d. The establishment of the true value of symptomatology, and the verification of that all-important fact, that opposite states and organs may produce similar symptoms. 4th. The knowledge of the vast class of latent diseases; in other words, diseases which exist without influencing the phenomena of animal life, or, in some cases, the phenomena of both animal and organic life. Diseases, either without symptoms at all, or only with such as previously were not supposed capable of leading to their detection. You know that the phenomena of life are divided into two classes, viz. those of organic or vegetable life, such as nutrition, circulation, absorption, respiration, secretion. While those of animal life, or the life of relation {so called, from its being the source of our connection with surrounding bodies), are the senses, the phenomena of mind, and muscular motion. The one life seems more under the influence of the ganglionic, and the other under that of the cerebro-spinal system of nerves. As some of the junior part of the class may not have accurate ideas as to the meaning of symptoms, I may state that disease is recognised by signs and symptoms. By signs, we mean those mechanical alterations, produced by disease, in the conditions of parts, which are recognisable to the external senses of touch, sight, and hearing ; changes in appear- ance, volume, shape, resistance, peculiarities of feel, and the pro- duction of sounds. We may make a diagnosis by signs alone. 8 STOKES’S THEORY AND PRACTICE OF MEDICINE.* Take, for example, a case of tympanitis. The abdomen is promi- nent, enlarged, circular, elastic, and sounding like a drum when struck. Thus we learn that the belly is distended by air. Now, symptoms are totally different; they consist in certain changes produced in functions ; and these functional changes are to be considered in a threefold manner:— 1st. Changes in the functions of the part itself. 2d. Changes in the phenomena of organic life. 3d. Changes in the phenomena of animal life. Let us take, for example, a case of inflammation of the stomach. We have, first, changes in its own functions—morbid sensibility, vomiting, thirst, anorexia. In the next place, we have changes in the functions of organic life—fever, from the action on the circu- lating system; hurried respiration, and cough, and hiccup, from the action on the respiratory system ; jaundice, from its action on the biliary system; suppression of the secretion of the skin, kidneys, &c. All these, you observe, are lesions of the functions of organic life. But we may have other symptoms ; prostration, headache, deli- rium, convulsions ; these are lesions of the life of relation, or animal life. Now, in many cases, we have to combine these sources of knowledge to form a correct diagnosis. Take, for example, a case of hepatitis. The patient has had pains in the hepatic region, fever, jaundice, hurried breathing, tenderness. After some time he has a tumour ; the side dilated; the hypochondrium dull on percussion. Well, the signs point out an enlargement of the liver; the symptoms, that the cause of that enlargement was an acute hepatitis. In general, we may state, that signs only declare the actually existing mechanical condition, while symptoms, either present or past, point out the cause of the change, whatever it may be. Both must be studied together ; but you will learn more from symptoms without signs, than from signs without symptoms. But to return to the results of the improved method of investigation. Great light was thrown on fever in general; and it is, I believe, quite true, that all the advances which we have made in the know- ledge of fever, are due to the prosecution of pathological anatomy. Almost all of what we may call our general knowledge of fever, is due to Hippocrates ; but anatomy has revealed its effects, its com- plications ; and the all-important fact, that the cause of its fatality is often local inflammation. This knowledge, however, is not so new as is taught by some modern systematists. Galen (De Affect. Intern, c. xli.) taught, that in continual fevers bleeding and cold drinks were the powerful remedies. Sydenham declares that the ignorance of the inflammations in malignant fevers, has been more fatal to the human race than the invention of gunpowder. Baglivi. that malignant fevers often depend on a visceral inflammation, and Van Swieten knew the frequency of intestinal ulcerations in typhus. GENERAL OBSERVATIONS. 9 Among the direct results of pathological anatomy, it is shown that disease is seldom confined to one organ, or even one system, and thus it has utterly shaken the nosological system of Cullen and his predecessors, which, you know, consisted in classifying disease by symptoms, which were supposed to point out a certain and single disease. For example, the nosologists class phthisis as an affection of the lung; but pathological anatomy has shown, that in many cases it is the result of a disease invading many organs and systems, and that the pulmonary disease is but a link in the chain of morbid actions. Pathological anatomy, also, has demon- strated the inflammatory nature of a vast number of diseases, and has thus given us a key to treatment, to prevention, and to pallia- tion, when the disease is incurable. The last grand result of pathological anatomy is the discovery that a vast number of affections, supposed to be merely lesions of function, are more or less connected also with alteration of struc- ture. Thus many of the dyspepsias of the nosologists are proved to be examples of gastritis, or of other organic diseases; cases of asthma turn out to be chronic inflammation with emphysema; the palpitations may depend on organic disease which has sprung from a carditis, and so on. I need not now dilate on the vast importance of such facts to practical medicine. But let us now come to an all-important enquiry. Is patholo- gical anatomy to be considered as the basis of medicine ? or is it, even when combined with clinical observation, the foundation of all medical knowledge ? This enquiry, you will at once perceive, involves the question as to whether Hippocrates and his followers have done any thing for the science, or whether medicine is wholly new, an infant, and consequently a weak and imperfect science. Are we to despise the works of the ancients, to be igno- rant of them, and to allow medicine to be in its infancy ? In fact, if we review the history of medicine from the Hippocratic era to the absurdities of Hahnemann, we find that there have been two orders of men, one constituting what we may term the school founders, who made a theory, and sought to square facts to meet that theory ; these have only brought disgrace on medicine. The other class consists of the Hippocratic observers; that is, of men who sought for facts, who collected and pondered on these facts, in other words, who were Baconian philosophers. It is the labour of these that has really advanced medicine. Asclepiades, who lived in the first century of the Christian era, declared that the medicine of Hippocrates was a cold meditation of death. The celebrated Thessalus, who lived under Nero, in writing to the emperor, makes use of the following words :— “I have fpunded a new sect, which is the only true one. I have been forced to this, because none of the physicians who have preceded me have discovered any thing useful, either for the pre- servation of health, or for the cure of diseases, and because Hip- pocrates himself has put forward many dangerous maxims.” And what was this new doctrine ? That nature in each case 10 STOKES’S THEORY AND PRACTICE OF MEDICINE. pointed out to the patient what was most fit for him, and that hence he should be diligently supplied with every thing that he fancied. We have next Paracelsus. He commenced his course of lectures at Basle, in the year 1526, by publicly burning the writings of Galen and Avicenna, and assured his auditors that a single hair of his head contained more knowledge than Hippocrates and his suc- cessors. He taught the cabalistic medicine, the intimate connec- tion between the planets and the viscera; he was a vitalist, but embodied his vitalism under the shape of a demon, who resided within the system, and which he called Archaeus. Diagnosis was to repose on the examinations of the stars, and not on symptoms. He invented the doctrine of tartar, which is the cause of all dis- eases, of accumulation, obstruction, and concretion ; “and I call it tartar,” says he, “ because it contains the oil, the spirit, and the salt, which burn the patient as hell does.” Hahnemann, the founder of the homoeopathic doctrine, may be quoted next as an example of these school founders; and he, like his predecessors, expresses himself with all that arrogance, which ignorance, when it pretends to learning, invariably assumes. Speaking of the Hippocratic medicine, he says— “ Since this art only consists in a gross imitation of a danger- ous and insufficient process, it must be admitted that the true medicine was not discovered until by me. It is the infallible oracle of the art of curing ; it is the sole mode of really curing dis- ease, because it reposes on an eternal and infallible law of nature.” And what is this mode and doctrine? We have it in four pro- positions, and it is hard to say which of them is most revolting to common sense. We are told that it is absurd to seek for the cause of symptoms in order to remove them; that we must cure diseases by the exhibition of substances which would otherwise produce them; that the dose is to be inconceivably small; and that there are three original diseases from which spring all the maladies which afflict mankind—syphilis, sycosis, and the itch. These are the fruitful causes of all diseases, epidemic, sporadic, idiopathic, and symptomatic. Like his predecessor in quackery and deceit, he, too, has is in his syphilis, sycosis, and itch, the oil, the spirit, and the salt, which burn the patient as hell does. Like Paracelsus, too, he maintains the curability of diseases, and is a disciple of the animal magnetism. Let us next see how Broussais announced his doctrine to an admiring world. “ After so many vacillations in its march, medicine at length follows the only path which can conduct it to truth—the observa- tion of the relations of man, with external modifications and the relations of the organs of man, one to the other” This is the physiological method, because it cannot be followed without study- ing life. I am more anxious to draw your attention to this doctrine, as Broussais may be considered as the source of the anatomical GENERAL OBSERVATIONS. 11 school, which, of late, was so completely the fashion—if I may use such a term; and it is a striking instance of the danger that attends the idea of our having made a discovery, to see a man like Broussais, than whom few have really added so much to medicine, falling into the same fault of arrogance and contempt towards his predecessors. At this moment, the medical world, particularly on the continent, are divided into two great sects. One may be called that of the patliologico-anatomists, the other the Hippocratists. The first declares that diseases are primitively local in all cases; that the symptoms—say in a case of fever—are only the results of a sym- pathetic irritation f rom some local disease, which is to be attacked with vigour ; that pathological anatomy is to be the foundation of all practice; that there is nothing approaching to a specific in medicine; and that nature makes little or no attempt to cure. Their favourite maxim is that saying of Bichat’s—“ What is observation, if we are ignorant of the seat of disease ?” This is the sentiment of an anatomist, but not of a physician ; and we must regret that it once escaped the author of the “ Researches on Life and Death,” a book of such interest and such beauty, as to captivate even the non-medical reader, and make the very name of Bichat be hallowed in our memory. Many are the diseases of which we know not the seat; yet in which observation —Hippocratic observation—is of the greatest utility. We know not the seat of fever, let the followers of Broussais say what they may to the contrary ; yet is observation of symptoms of no avail in fever ? Are the effects of contagion, the history and nature of epidemics, the termination by crisis, the results of treat- ment, of symptoms as connected with prognosis—is the observation of these useless or unnecessary ? Sydenham knew not the seat of variola ; yet he declared the true principles of its treatment. There are very many diseases on which pathological anatomy throws but a negative light—if I may use such a term—particu- larly affections of the fluids, and the neuroses. So much for the doctrine of the anatomical school. I beg of you not to misunderstand me as undervaluing pathological ana- tomy ; I only wish to show you its true value. I believe there could hardly be adduced a single fact in pathological anatomy that has not its distinct bearing on practical medicine. And it is true that the diseases whose treatment is best understood are those whose pathological nature are best known. Even in fever, the actual nature of which has not been revealed, great advantage has been derived from anatomical researches ; for all the advance in our knowledge of this Protean disease consists in ascertaining the number, nature, and seat, of the local inflammations which accom- pany or rise in the course, and complicate the disease. Let us, lastly, revert to the opinion of the Hippocratists. They admit that vast advantage has arisen from pathological anatomy; but they see that its light is limited within certain bounds. They 12 STOKES’S THEORY AND PRACTICE OF MEDICINE. believe that great advantage is to be derived from the careful study of symptoms, even in cases whose pathological nature is not revealed by the knife. They believe that there are many diseases whose local origin cannot be demonstrated; for instance, fever. They deny that pathological anatomy is always to be our guide ; but admit a rational empiricism, and the use of remedies which may be called specifics ; and. lastly, they hold that nature, in many cases, makes an attempt to cure; and that the physician, in the words of Hippocrates, is to be the minister and interpreter of nature, rather than her master. Let us, then, combine the precepts of the founder of medicine with the lights of modern science. Let us take observation, and that observation rendered fruitful by study, for our guide; and let the observation equally embrace the phenomena of the living as well as the dead. Let us be Hippocratists in the dissecting room as well as at the bed-side. By comparing the practice of these two schools, we get more accurate ideas as to their doctrine. The anatomists, holding that all diseases are local, direct their whole attention to the discovery of the lesion, and its connection with symptoms. This, with their doctrine that almost all diseases are inflammatory, leads them to a strict general and local antiphlo- gistic treatment. Fever is to them symptomatic, and the supposed source is to be vigorously attacked in the commencement. Diathesis, the nature of the epidemic, and the powers of nature to effect a cure, are comparatively neglected. They inhibit pur- gatives for fear of increasing the local inflammation, and lose many patients for want of a timely support of the powers of life. They deny specificism in disease as well as in medicine, and are sorely puzzled to explain the extraordinary powers of bark, and mercury, and sulphur, and iodine. They despise the expe- rience of the past. The true Hippocratist, on the other hand, believing that we have not yet arrived at the knowledge of the local origin of all diseases, and particularly fevers, grounds his practice accordingly. He draws his experience from the recorded knowledge of the past, and his own unbiased observation. When he recognises a local inflammation, he meets it with judgment, taking into account the habit, diathesis, epidemic, constitution, and tendency to crisis. He trusts much to nature, and watches her operations, particularly in fever. He is not afraid of moderate evacuations ; the phantom of a local inflammation does not always haunt him; and even where he recognises its existence, that does not prevent him from using a stimulating and supporting treatment, if the general state of the patient requires it. He treats particular diseases by particular remedies, the utility of which has been proved by experience— such as syphilis, scrofula, intermittent fever, and so on. He uses the expectant medicine, which is not inactive treatment, but founded on the observations of the powers of nature—“ Natura morborum medicatrixbut he never loses the opportunity of REMARKS ON LOCAL DISEASES. 13 doing good, when such presents itself, remembering the first aphorism of his great master :— “Occasio prseceps.” I have great hopes for medicine, for I see men’s minds turning to the true path ; and I trust that all whom I now address will deem themselves as labourers in the great work. Think what a noble science you profess ! the only one relating to earth-born things, which, while it ennobles the mind of man, yet softens and expands his heart; whose source is all science, whose end is good to man. Above all things, follow truth ; nature can never deceive—see that you be her faithful interpreter. The great evil is, that there has as yet been adopted no means by which the experience of the past can be brought fully to bear on the actual teaching and practice of medicine. Too often has the physician to create his own instru- ments. But when all the scattered facts of medicine are collected, whether they be the observations on the living or the dead body, as old as history, or as young as to-day; when these votive tablets are hung up in the temple of truth, and their facts verified, com- pared, and classified, then, and not till then, will you see medicine in all her glory.' LECTURE II. General remarks on local diseases—Fixed rules for the guidance of students—Great importance of diagnosis—Existence of pure fever rare—Doctrine of the Humoralists and of the Brownists—Pathology of the digestive system. I commence the course by entering at once on the subject of particular diseases. I am aware that the common practice is to occupy the early part of a course on the theory and practice of medicine with preliminary discussions on general pathological subjects. To this I have strong objections. Every man who as- sumes to himself the office of teacher, no matter what the fact may be, should presume that his auditors are ignorant of the subject he is about to teach; if he does not he must be unjust to his class. Some of the class must be ignorant of the information he wishes to convey, and he should take it for granted that all are so. To commence with the consideration of general disease would argue that the whole class was acquainted with the subject in all its bearings, and capable of understanding its principles without any previous illustration. I think this is beginning at the wrong end. My plan is first to teach the facts, and then the general prin- ciples and conclusions to which these facts lead. It is of the deepest importance in the study of medicine to be able to form a collection of laws or fixed principles. In your professional career, nothing will give you so much satisfaction as having in 14 STOKEs’s THEORY AND PRACTICE OF MEDICINE. your minds a number of established facts and fixed rules to bear on every case which comes under your cognisance. We com- monly hear of the uncertainty of medicine and the instability of its practice, it is said to have as many phases as the moon, and as many changes as the tide; but, after all, I think this expression is more general among those who know little than among those who know much. Those who have successfully laboured in treasuring up a store of deep and extensive knowledge are firmly convinced, that, though some cases are involved in doubt and obscurity, the general certainty of medicine is at present increased far beyond what it was in former times. No man, except one in full and extensive practice, earned by industry and capacity, can be aware of the vast improvements of modern practical medicine, and of the number of lives which are saved by the judicious treatment which the rapidly progressive improvement of medical science has intro- duced. Medicine is much more certain now than it was in past times. There are two reasons for this, one of which is, that at the present period diagnosis, the guide and master-key to sound treatment, is more certain. Here, gentlemen, is a great source of certainty in the practice of medicine. You will find, in the course of a few years, that the old saying of “doctors differ,’5 will become less frequently applicable, because, as the education and acquire- ments of medical men become more extended, diagnosis will be reduced to fixed rules, and difference of opinion will be very seldom observed. A vast number of local diseases, formerly wrapt in obscurity, are now detected with the most unerring certainty, and this certainty of diagnosis must bear on fixed principles of treat- ment and similarity of practice. Another vast source of increased certainty is the fact, now extensively established, that the element of a great number of diseases is the same. This is an important law, because the deduction from it is, that the principles of treat- ment are the same in these cases. The principles of treatment in a case of hydrocephalus and in a case of vomiting from gastritis may be, and often are, completely identical, because, in many cases, both are reducible to a common action. In the one case we have to deal with inflammatory action in the stomach, in the other we have to treat an inflammation of the membranes of the brain. The principle in both cases is to deplete the suffering organ and to diminish or remove every thing that keeps up irritation. Patholo- gical anatomy, too, has effected a vast deal for medicine by the improvements in diagnosis which it has introduced, and by re- ducing to one class a vast number of affections formerly supposed to be unanalogous and distinct. Before I commence entering on the consideration of the patholo- gy and treatment of diseases of the digestive system, it is necessary that I should mention another peculiarity of the mode of teaching the theory and practice of medicine adopted in this school. The ordinary way of lecturing medicine in the schools is this: the teacher begins by going over, at great length, the whole subject of fevers, and then proceeds to the consideration of the signs, symp- REMARKS ON LOCAL DISEASES. 15 toms, and treatment of local diseases. We reverse this mode here; we begin by teaching the pathology and treatment of local diseases, or affections of particular organs, and having studied these with care and attention, we then proceed to the consideration of fevers. In point of fact, we are thoroughly impressed with the truth of this splendid conclusion in medicine, that local diseases may be considered, as it were, the alphabet of fevers, and that to have a distinct and accurate conception of the whole subject of fever, it is essentially necessary that we should be acquainted with all kinds of local disease. To commence with a class which the teacher presumes, or should presume, to be ignorant of the phe- nomena of local diseases, unacquainted with the rules on which their diagnosis depends, and unacquainted with the principles which should regulate their treatment—to begin with such a class by entering at once on the subject of fever, would, in my opinion, be extremely wrong. You will read in books and hear teachers speak of bilious fevers, of nervous fevers, of catarrhal fevers, of gastric fevers, and of simple fevers. These expressions are founded on the fact of the complication or noncomplication of fever with local disease in various parts of the system. If simple fever was the rule, and its complication the exception, then, indeed, there would be some reason for pursuing the ordinary track of medical instruction, and we might commence by teaching the subject of fever, independent of local inflammation. But the truth is, that fever, in the simple form, is the exception, and its complication the rule, and that to have a correct idea of fever, in the general acceptation of the term, we must previously possess an intimate knowledge of the affections of particular organs. The progress of medicine has established, by the most unquestionable evidence, that simple fever is a matter of extremely rare occurrence, so rare, in fact, that you might pass through the practice of a fever hospital for years without meeting with a single case which you could say was, through its whole course, a case of pure, essential fever. Sooner or later its character is changed, and the complication with visceral disease comes on; you may take this with you as a well- proved fact. You will have, at some period, a complication with local disease in the head, or local disease in the chest, or in the belly, or in the circulating system, or perhaps all the great viscera in the body will be simultaneously affected. My expe- rience on this point, after having attended the fever wards of the Meath Hospital many years, is this, that among all the cases which were admitted under such circumstances, there were very few indeed in which I could not say that the patient had something more than fever. Many were admitted who presented no,indica- tion of disease in the head, chest, or digestive tube ; all that could be said of them, at the period of their admission, was, that they had fever ; but my experience of them is, that, in a vast majority, there was, during their progress, unequivocal evidence of the su- pervention of visceral disease. I do not go as far as the disciples of Broussais have gone, nor do I mean to say that all fevers are 16 STOKES’S THEORY AND PRACTICE OF MEDICINE. symptomatic ; all I assert is that, at some period, most fevers are complicated with local disease. I admit that there is a vast number of symptomatic fevers, but I believe there are two which are essen- tially simple, typhus and intermittent. The progress of medicine has shown that these may exist in the simple form, and that their complications may be secondary ; this I believe to be the fact, but the almost invariable liability to complication is a point of the highest importance. We scarcely ever see typhus accompanied by symptoms of local disease ; and, with respect to intermittent, in ninety-nine cases out of a hundred, visceral disease of the head, or chest, or belly, may, and will, supervene. Another great fact bearing on this subject, and which patholo- gical anatomy has established beyond the possibility of a doubt, is, that in the great majority of cases having a fatal termination, death is caused by disease of some particular organ or organs. The old notion of the cause of death was, that the patient died of debility or exhaustion. In cholera, in tetanus, in hydrophobia, we cannot, to be sure, demonstrate any appreciable lesion of structure, and we may say, if we like, that the patient died of debility ; but this does not hold good in cases of fever, for on dissection you will generally find disease sufficient to account for death, even though there had been no fever at all. From these circumstances it fol- lows that in the management of fevers, the attention of the physi- cian must be directed to the local affections, or, at all events, that to understand fever well and treat it successfully, he must be ac- quainted with the nature and treatment of every form of visceral disease. It will be sufficient for me to call your attention to this fact, that there is not a single acute local disease which may not occur during the progress of a fever. This is a broad and general proposition. If you look to the nervous system you will find, in patients who have died of fever, traces of lesion in almost every part of it, inflammation or congestion in the cerebrum, in the cere- bellum, and in the spinal cord. If you go to the respiratory system, you will see all kinds of shades, and varieties of inflammatory action, thickening and ulceration of the bronchial membrane, hepa- tisation, congestion, and destruction of the parenchymatous tissue, effusions of lymph, serum, or pus, into the pleural cavities. As you proceed in your examination you will discover new lesions; you may see the whole lung filled with lately formed tubercular matter, you will meet with the destructive ravages of phthisis. You will find the pulmonary tissue converted into a dark and fetid mass by gangrene. You may see carditis, hypertrophy, inflamma- tion of the external or internal coverings of the heart, inflamma- tion of the lining membrane of the arteries, phlebitis, (a common occurrence in typhus fever,) and passing on to the lymphatic sys- tem, you will often find evident traces of inflammation in its glands and vessels, an occurrence which I shall be able to demonstrate to you when treating on the subject of gastric fever. If we go to the digestive system we find that disease has here taken a wider range ; congestions and ulcerations of the stomach and intestines, REMARKS ON LOCAL DISEASES. 17 morbid states of the liver, congestion and inflammation of the spleen or kidneys, evidence the fatal extent of local inflammation. I think I might safely challenge any one to point out any one single organ which may not become diseased during the progress of a typhus fever. I do not wish you to suppose that typhus is a symp- tomatic affection. I think we may define it, in general terms, as a diseased state of the whole system, in which various local diseases arise, modify the character of the original complaint, give it an addi- tional intensity, and are generally the cause of death. Go round the wards of an hospital during the prevalence of an epidemic fever, examine every patient in succession, and bring this principle to the test. You will see one labouring under the morbid excitement of high delirium; his face injected, his eyes sparkling, his carotids throbbing with intensity. Come next day, and you will find him in a state of profound coma, perfectly insensible to every thing around him :—two or three days afterwards he is dead. You follow his body to the dissecting room, and open his brain ; unequivocal marks of excessive congestion, inflammation of the substance of the brain, or of its membranes, sufficiently indicate the cause of the fatal termination. Here is a case of inflammation of the brain; you find another with cold skin, his face of a dirty hue, faintly tinged with red, his breathing quick and hurried, and the spitting- vessel by his bedside filled with adhesive mucus tinged with blood; you percuss his chest and find dulness over the whole surface of one lung; you apply the stethoscope and discover intense bron- chitis, hepatisation, or suppurative pneumonia. Farther on you see another in a state of deep prostration, with a sunken counte- nance, constant hiccup, and low delirium. Take down his bed- clothes, and you find his belly swelled, tympanitic, and tender on pressure; then his tongue, lips, and gums, are parched and encrusted with dusky sordes ; his thirst is insatiable ; he vomits, and has an emaciating diarrhoea. After death you find traces of an extensive and fatal gastro-enteritis; in others you will find exemplified the very climax of inflammation, and all the three great cavities are simultaneously affected. But these, you will say, are cases in which the complications are evident, and where an ordinary knowledge of the phenomena of local disease will be quite a sufficient guide. Well, here is another case. You will meet with instances of fever without any apparent local symptoms, where the patient lies in what you would consider a quiet state, and free from danger : nothing seems to be the matter with him, except that he is very weak ; he perhaps does not sleep at night, and his tongue is a little foul; he complains, in fact, of nothing but weakness and some thirst, and you think his fever is going on very well. Some morning or other, on coming to the hospital, you are astonished to see the change which has been wrought in him since the day before; his countenance is altered, his pulse can hardly be felt, and life is fast ebbing away. You ask the nurse about him, and she tells you that, during the night he suddenly complained of violent pain in his belly. On 18 STOKES’S THEORY AND PRACTICE OP MEDICINE. examining him, you find distinct evidence of intense peritonitis, and, after death, dissection reveals the existence of a perforating ulcer of the intestines, of which there was apparently no sign during life, except fever and the unexpected occurrence of peri- tonitis. The frequency of the complication of local disease with fever, its insidious latency, and the fact, that death, in the majority of fever cases, is caused by visceral inflammations, all clearly point out the necessity of being intimately acquainted with every modi- fication of local disease before you proceed to the study of fevers. I commence with the digestive system. I am anxious to do this for several reasons, but for none more than this—that to the im- provements made in the pathology of the digestive system we owe much of the rapid advancement of modern practical medicine. Before our time the pathology of the digestive system was very little known, and if not quite a terra incognita in medicine, there existed respecting it a great deal of misconception. The schools were deeply tinctured with the doctrines of the Humoralists and the Brownists; and this had the effect of giving rise to irrational theories and false notions of the true state of the system in disease. The humoral pathologists, who sought for disease in an alteration of the fluids alone, neglected the study of visceral lesions ; and when they turned their attention to the digestive system, they only considered it, its secretions, and not its actual condition or the state of its sympathies. The liver, with them, was an organ of the highest importance, and the secretion of bile claimed a vast share of their attention. To it they gave a paramount influence, and to an alteration in its quantity and quality they attributed most of the changes which occur, not only in the digestive tube, but also in the whole system; and hence the great object of their practice was to attempt to restore its healthy condition, convinced that if this were once accomplished every thing would go on favourably. From this, too, arose the purgative plan of treatment in various forms of intestinal disease, a plan too often rashly pursued, even where there was unequivocal proof of inflammation in the diges- tive tube. Their sole purpose was to evacuate sordes, to produce a flow of healthy bile, and to eliminate depraved secretions ; and they did this without possessing any knowledge of local inflamma- tion, or of the effects of disease of the digestive system on other organs. The followers of Brown, on the other hand, only admitted disease of the digestive system in a state of intense, manifest vio- lence, as, for instance, ileus or violent enteritis; but, in the great majority of cases, they did not recognise intestinal inflammations, because their prominent symptom was prostration, or, to use their own terms, an asthenic condition of the whole system. They saw nothing but prostration ; they prescribed for nothing but debility; they gave wine instead of iced water ; ordered bark instead of local depletion. They exasperated the disease by stimulants; and then, thinking they had not gone far enough, they heightened the stimu- lant and doubled the debility. Another cause of the low state of pathology in former times was REMARKS ON LOCAL DISEASES. 19 the genera] neglect of dissection. The fact is, that in fever there were no post mortem examinations made, until very lately. Mor- gagni, who did so much for pathological anatomy on almost every other subject, did little for fever, because he was afraid to dissect the bodies of persons who had died of a contagious disease. This was the idea which prevailed among the older pathologists ; and hence this source of knowledge was avoided, and for many succes- sive centuries the state of the viscera in fever was a matter of spe- culation, doubt, and uncertainty. Even at the present day it is only done by the ardent pathologist, who cares not about filth and stench, and who had rather encounter the miasm of contagion than remain in the mists of error. Nothing is more common, I regret to say, even at the present time, than this :—A person says he has dis- sected cases of fever, and when asked whether he had examined the intestinal canal, he says that the intestines appeared healthy, but he did not make any particular inspection of them ; he only opened the belly, and, finding no trace of inflammation in the peri- toneum, he went no farther. Now nothing can be more useless than such an examination. If we compare the information afforded by an inspection of the serous membranes of the three great cavities, we shall find that the least is given by an examination of that of the abdomen. Disease of the substance of the brain is rare with- out affections of its investing membrane, disease of the substance of the lung is exceedingly rare without the occurrence of disease of the pleura, but you may have most extensive and fatal disease of the intestinal canal, without the slightest lesion of the peritoneum. In this point, therefore, it differs from the pleura, and from the arachnoid membrane. The fact of the rarity of disease of the peri- toneum in cases of disease affecting the parts beneath, was noticed by Dr. Graves and myself, in our report of the Meath Hospital, and also by Mr. Annesley, in his account of the diseases of India. You will see cases of hepatic abscess, which present a distinct tumour externally, and where you can detect a perceptible fluctuation ; and yet, if you examine these cases after death, you may not find any adhesions of the peritoneum, even in the situation of the ab- scess. You will find the mucous and muscular coats of the colon extensively destroyed, you will see the stomach all but perforated, you will meet with cases where the whole ileum is one extensive sheet of ulcerations, with no disease in the adjacent peritoneum. In entering on the consideration of diseases of the digestive system, we shall begin first with the mucous expansion of the sto- mach and intestines, and then proceed to the affections of the solid viscera connected with them. The mucous surface of the stomach and intestines is of enormous extent and extraordinary sensibility, possessed of innumerable and powerful sympathies; its influence is felt by almost every organ in the body, formed for receiving and elaborating every thing destined for nutrition ; its conditions, both in health and disease, are entitled to the deepest and most attentive consideration. To facilitate the study of its affections, and for the sake of some practical arrangement, we shall divide its diseases 20 STOKES’S THEORY AND PRACTICE OF MEDICINE. into five classes, beginning with the oesophagus, or that portion of the digestive tube which is above the diaphragm, and then pro- ceeding to the stomach, duodenum, ileum, colon, and rectum. But, in order to give you a clear idea of diseases of the intestinal canal, I shall commence with diseases of the stomach ; because, if you consider the whole range of animal life, you will find that its func- tions are the most important, the stomach constituting, as it were, the source and fountain of life, which is nutrition, and giving by its existence a character to all the upper classes of animals. No organ possesses such remarkable sympathies as the stomach, whe- ther we look upon them as sympathies of organic or of animal life, none possesses such remarkable power and influence in modifying the condition of every part of the system. But, putting aside phy- siological reasons, let us come to practical matters. The success of almost every form of medical treatment, all the advantages to be derived from the administration of internal medicine, depend upon the stomach ; in fact, in whatever point of view we consider it, we must look upon a knowledge of the state of the stomach as the great key to sound and successful practice. It is a most useful reflection to consider the extraordinary fre- quency of disease in some portion of the digestive tube. It is now admitted by every person possessed of experience in the causes of mortality, that more human beings die with acute or chronic dis- eases of the digestive tube than with diseases of any other part of the system. This has been established by numerous investigations, and is admitted by the best pathologists ; and, indeed, I think it can be easily accounted for, when we call to mind how many per- sons die of some form of fever or other, when we look to the rava- ges of remittent and yellow fever, to the hundreds of thousands who annually perish by the various classes of fevers. Now, in almost every one of these cases, disease of the digestive system forms one of the most prominent pathological characters. Recollect, besides, all that die of dysentery, whether sporadic or simple, and here is inflammation of the colon; see, too, how many die with diarrhoea— here, too, there is intestinal disease; remember how many die of the malignant intermittent of the West Indies, in which unequivocal proofs of disease of the stomach and intestines have been found. Observe what a close connection there is between tubes mesente- rica, and inflammation of the mucous membrane and surface of the intestines ; think what a vast number of persons fall victims to the harassing effects of constipation and dyspepsia ; and recollect that there is a host of diseases in which the train of morbid phenomena commences in the digestive system, and then exhibits itself by functional alteration or organic disease of other parts. We recognise the presence of disease in the digestive tube, first, by the local phenomena and the lesion of the digestive function, and next, by the sympathetic relations of other parts, by the sym- pathies of the respiratory system, of the circulation of the skin, and of the nervous system. I shall enumerate the local phenomena and functional lesions: vomiting, anorexia, thirst, jaundice, pain, REMARKS ON LOCAL DISEASES. 21 tenderness on pressure, tympanitis, changes in the character and quality of the discharges, constipation. Here are a set of functional lesions and local phenomena; let us now consider the sympathetic relations ; these are fever, heat of skin, suppression of the cutane- ous secretion, suppression of the secretion of urine, morbid states of the tongue and pulse, pains in the chest and cough, hurried breathing, and palpitations of the heart. In the next place, we may have prostration of strength, delirium, coma, convulsions, tetanic spasms, and other symptoms of functional disease of the brain j these are all sympathies of relation. Now, in the first place, I have to remark, that there is a great deal of variety in the combi- nation of these symptoms. On what does this depend? on a variety of circumstances; sometimes on the intensity or extent of the in- flammation : sometimes on the situation of the disease ; sometimes on the complication of the affection; sometimes on the various modes and degrees of susceptibility of the individual. All these causes tend to produce a great variety in the disease, and an exten- sive modification of the sympathetic relations. For instance, in some cases inflammation of the stomach and intestines is so slight that the patient is not prevented from going about and pursuing his ordinary avocations; in others, on the contrary, the patients are struck down at once by the violence of the disease, and are carried off by the fever which accompanies it before the inflamma- tion is completely developed. It varies also according to situation; there is a difference between gastritis and dysentery: in the former we have an inactive state of the great intestine, and consequent constipation ; in the latter, the colon is thrown into violent action, and there are frequent dejections. Disease of the duodenum is attended with a very remarkable peculiarity, being very frequently complicated with jaundice ; here is a modification produced by situation. Again, inflammation of the ileum is attended with a very curious peculiarity, namely, the absence of pain. The patient states, that he feels unwell, he has obscure symptoms of intestinal disease, but it is neither dysentery nor gastritis; you investigate it with care and find that the ileum is in a state of inflammation. Yet the patient does not complain of any pain, and this is another peculiarity depending on situation. But in considering the differences which depend upon intensity, extent, and situation of disease of the intestinal canal, we must not omit those which depend upon tissue. If disease be confined to the mucous membrane of the intestines alone, we may have an extremely diffused and extensive inflammation, sufficient to destroy life, without any pain being complained of by the patient; it is a painless though fatal disease. Recollect this, extensive and fatal inflammation without pain. In former times the ideas of pain and inflammation were inseparable. Thanks to the light which patho- logy has shed upon modern medical science we are now acquainted with this seeming anomaly, and can conceive the existence of ex- tensive disease of mucous surfaces unaccompanied by pain. But let the inflammation seize on the muscular tissue, the character of 22 STOKES’S THEORY AND PRACTICE OF MEDICINE. the disease is instantly changed, and the pain is dreadful. Here is a case in which difference of tissue is to be taken into consider- ation. The phenomena and sympathetic relations of intestinal disease may vary also according to its complication, and here we come to investigate one of the most beautiful laws of the human economy, namely, that the more complicated a disease is the more latent will will be any local lesion. This is a point that should never be forgotten. For instance, enteritis by itself is much more easily recognised than when complicated with pneumonia, or with irrita- tion of the brain, and gastritis is but too often completely masked by being combined with irritation of the bronchial mucous mem- brane. Lastly, we have the varieties which depend on different degrees of susceptibility. In one person we may have only slight cerebral irritation, in another high excitement, in a third delirium and extraordinary convulsions. The variety, then, in the modifi- cations of disease, and the combination of sympathies, is very great, and is referable to the extent and the intensity of the inflammation, difference of situation, complication of disease, difference of tissue, and different degrees of susceptibility. I shall give examples of these at my next lecture, and then proceed to the pathology and treatment of gastritis. LECTURE III. Pathology and treatment of diseases of the digestive system—Different forms of gastri- tis—Pathology of this disease imperfectly understood by the ancients—Gastritis and enteritis not always found in connection—Phenomena characterising acute gastritis —Symptoms and sympathetic relations—Diagnosis—Gastritis simulating other dis- eases. The consideration of the pathology and treatment of diseases of the digestive system shall occupy our attention to-day. I shall commence with the study of gastritis, and to this subject I would entreat your undivided attention ; not that I have any thing very new to communicate, but because I believe that many of the state- ments, which are connected with this disease, will be found to rest on the basis of fact and truth, many of them will be found useful in your future practice, and this subject, I fear, is not sufficiently considered in the schools of medicine of this and the sister countries. The older authors describe gastritis as occurring under two dif- ferent forms, one of which they termed phlegmonous, and the other erysipelatous. The advanced students know the meaning of these terms, and that they are admitted as significant of different modifi- cations of the inflammatory process, but to those who are not ad- vanced I shall state that it is very difficult to give an accurate idea of these terms, so far as they are applicable to cases of internal DISEASES OF THE DIGESTIVE SYSTEM. 23 disease. Blit we may attempt a general definition by saying, that phlegmonous inflammation occurs in a good constitution, and under favourable circumstances, that it is an inflammation of a bold and distinct character, requiring and admitting of depletion, and, like that on the external parts, terminating in healthy suppuration, or adhesion. Erysipelatous inflammation is (described to be) a disease of a different kind, occurring in bad and debilitated constitutions, and under such circumstances that the same treatment, employed in the phlegmonous form, is more or less inadmissible ; and when stimulants are necessary, if not in the commencement, at least at a very early period of the disease. It is quite impossible to found any system of pathology on this division into phlegmonous and erysipelatous ; we are, however, sometimes obliged to make use of it for want of a better. The terms themselves are highly calcu- lated to mislead. Healthy inflammation, which is all but a con- tradiction in terms, may occur in a debilitated constitution, and erysipelatous in a strong one. The latter of these, too, is particu- larly erroneous, as we now know that erysipelas may occur under opposite circumstances. In the one case, requiring the lancet and leeches, and purgation ; in the other, demanding a stimulant and tonic treatment. In speaking of gastritis I do not intend to adopt this division, because it would be likely to embarrass you, and, in truth, it is unnecessary, as there is no difference in the (principles of) treatment, whatever may be the form of this inflammation. The proper way to consider gastritis is to look upon it as a disease, presenting, on the one hand, symptoms of extreme violence and urgent danger ; on the other, feebly shadowed out by the phe- nomena of ordinary and slight indigestion. Between these there are many shades and numberless gradations. The phlegmonous gastritis of the old authors implied a violent and extensive inflam- mation, in which all the coats of the stomach were implicated ; but, in treating of the subject of gastritis in these lectures, I shall only allude to inflammation of the mucous membrane and glandular apparatus of the stomach. The other tissues are sometimes en- gaged, but the mucous membrane, constituting the most important of these tissues, and forming an exquisitely delicate vasculo-nervous expansion, is, in the great majority of cases, the principal seat of inflammation, and to this I would direct your particular attention. The true pathology of gastritis was but very imperfectly under- stood by the ancients. They knew enteritis and gastritis as intense inflammations of the coats of the stomach and intestinal canal, ac- companied by violent pain and fever, but they had no conception of their various shades and modifications. For a knowledge of the true nature of gastritis, and of its numerous varieties, we are in- debted to modern pathology, and it is the boast of pathological anatomy to say, that in this instance its labours have shed a broad and vivid light on a class of diseases previously involved in deep obscurity. It has been stated, that it is impossible to separate the symptoms of gastritis from those which characterise enteritis, and the reason 24 STOKES’S THEORY AND PRACTICE OF MEDICINE. given for this is, that the two affections frequently co-exist. This is a proposition of vast importance. It is said, that in cases where you have gastritis, the chances are that there is more or less of enteritis ; but according to this doctrine, if a man has gastritis the probability is that he has inflammation of some other portion of the intestinal canal. Broussais, in the 138th proposition, makes the following observations:—“Inflammation of the stomach, or, as it is called, gastritis, is never found except in conjunction with disease of the small intestine. It is better, therefore, to give it the name of gastro-enteritis ; and even in those cases, in which we have enteri- tis, we have gastritis as the irritative.” Now if this proposition is true, it is one of very great importance, and entitled to a large share of our attention, in studying the phenomena and treatment of inflammation affecting the digestive tube. Pathology, how- ever, has proved that these inflammations are not always found in connection. Andral gives many cases, in which disease existed separately in one or other portion of the intestinal canal; when it was found in the stomach and not in the duodenum or ileum, and when it was found in the ileum, but not in the duodenum or sto- mach. I myself have seen many examples of gastritis without disease of any other part of the digestive tube, and disease of va- rious parts of the digestive tube without the co-existence of gastric inflammation. But I believe the proposition is generally true, particularly in cases of fever, in which you have secondary in- flammation of the digestive tube during the course of the disease. When inflammation attacks the intestinal mucous surface during the progress of a fever, you will, in most cases, have these two diseases combined ; the patient generally presenting symptoms of gastritis, and, at the same time, symptoms of enteritis affecting the lower third of the ileum. Let us now proceed to investigate the phenomena which cha- racterise acute gastritis. Here I must remark, that, as an idiopathic disease, acute gastritis is extremely rare. This is a very curious circumstance. When we compare the stomach with other viscera, we shall find that one of the most remarkable differences between it and other organs is, that it is much less liable to be attacked by violent inflammation, as an idiopathic affection. This is an inte- resting fact. So rare, indeed, is the violent form of gastritis, that our knowledge of the symptoms which indicate intense gastric inflammation is principally drawn from the study of cases of acute gastritis caused by swallowing corrosive poisons. We very seldom meet with an inflammation of the stomach, presenting those decided characters so frequently witnessed in similar affections of other organs. We may attempt to explain this fact, by considering what the functions of the stomach are, and by recollecting that it is the organ of the body, whose functions require that it should be most frequently in a state of great vascular excitement. Every one is aware that the vascularity of the stomach is amazingly increased during the act of digestion ; but it is to be remembered that this is a physiological and not a pathological condition. If the stomach 25 DISEASES OF THE DIGESTIVE SYSTEM. were as liable to inflammation as other organs, it could no longer carry on its functions with safety ; every meal would prove a stimulus sufficient to excite inflammation—every digestion would be followed by gastritis. Nature has provided against such acci- dents. Let us take a brief review of the symptoms of acute gastritis :— intolerable thirst, desire for cold and acidulated drinks, constant nausea and vomiting, pain and burning sensation of heat about the stomach, and fever—these are the symptoms of a violent gastritis. It has been stated, that in gastritis the fever is at first inflammatory and afterwards typhoid. If authors mean by this, that the patient rapidly falls into a low typhoid state, the observation is true. There is no form of inflammation, except that which! accompanies severe peritonitis, in which the typhoid state comes on so rapidly. Inflammations of the digestive tube differ, in general, from similar affections of other organs, chiefly in this—prostration rapidly su- persedes excitement. A patient labouring under inflammation of the brain will exhibit, for a long time, decided symptoms of high excitement, and of what has been termed the diathesis; acute pneumonia and inflammatory affections of other parts will go on for days, without prostration, and require the use of the lancet; but gastritis is a disease in which the inflammatory symp- toms, as they are called, last but for a very short time. In violent cases the irritation of the stomach is excessive, and every thing is rejected. I have seen cold water thrown up almost immediately ; I have seen effervescing draughts rejected the moment they were swallowed, and make the patient evidently worse. The epigastric region and the left hypochondrium are exquisitely tender on pres- sure, and the tenderness differs from that of peritonitis in this, that it is almost always localised. The patient screams with agony when you touch the epigastrium, but will bear pressure freely on the lower part of the abdomen. Now, with respect to the sympathetic relations of gastritis, I have to remark, that they are very numerous. First, as to respiration— it is extremely quick and hurried; the heart, also, is violently ex- cited ; and hence gastritis has sometimes been mistaken for pneu- monia and pericarditis. Sometimes we have bronchitic cough; the patient is restless, gets no sleep, and is extremely uneasy ; his skin is hot, his bowels confined, his pulse rapid and small. In the second stage, he is beginning to sink, his features become con- tracted, his skin cold and pale, his extremities sunk below the na- tural temperature; he now bears pressure; the vomiting is changed for regurgitation of every thing he swallows ; low delirium super- venes, and he dies. It is of the greatest importance to attend to the sympathetic rela- tions of gastritis, for this reason, that in many cases the local symptoms are all but wanting, and the disease is only to be known by its sympathetic relations. Before I enter on this subject I shall make one or two remarks on some symptoms which have not been attended to by many practitioners. One of these is an incapability 26 STOKES’S THEORY AND PRACTICE OF MEDICINE. of swallowing, sometimes so great that all ingesta, whether fluid or solid, are rejected. This will sometimes arise from spasmodic stricture of the oesophagus or cardiac orifice of the stomach ; and, as there has been no other cause revealed, by dissection, in several cases in which this symptom was present, we must admit this as one of the causes of the dysphagia, which, on some occasions, attends gastritis. This symptom is most commonly accompanied by tightness and oppression about the praecordia. The patient, feeling a load or weight, as he expresses it, in this situation, thinks it would be relieved by vomiting, and begs his medical attendant to give him an emetic, which is sometimes administered, and pro- duces very bad effects. There is only one case in which an emetic can be given in gastritis, and that is, where indigestible or irri- tating substances in the stomach give rise to irritation, and when we cannot expect a favourable termination until we effect their removal. There is another most disagreeable and distressing symptom, generally occif|ring in cases in which there is inflammation about the cardiac ojfcce of the stomach—I mean hiccup. Hiccup is a most harassin™symptom; it does not allow the patient a moment’s rest; in his brief and uneasy slumbers he is conscious of it, and is constantly awakened by it. Now, this is also one of the results of gastritis, with inflammation about the cardiac orifice. I say this, because I have seen it in many cases, in which there was distinct evidence of inflammation about the cardiac orifice of the stomach; and, in three instances, I have verified it by dissection. I do not mean to say that every case of hiccup is indicative of disease of the cardiac orifice, but I believe it is a very frequent accompaniment. The case of a celebrated professor of languages was a remarkable example. A short time previous to his death, he came from Liver- pool in one of the steam packets. He was always subject to sea sickness ; but on this occasion he was extremely ill, and vomited during the entire passage or sea voyage. He complained of his stomach for some time, and then got hiccup, which resisted every kind of treatment, and continued without any abatement up to the time of his death. On opening the stomach, this organ was found in a state of intense inflammation, particularly about the cardiac orifice. You can see the stomach (of which a very good prepara- tion has been made by Dr. Houston) in the museum of the College of Surgeons. There was another very remarkable case in the Meath Hospital. A patient was admitted who had laboured under acute pneumonia, for which he was treated with tartar emetic, and the symptoms rapidly declined, but vomiting and hiccup came on, and the latter symptom continued until death. We opened the body eighteen hours after his demise, and found the lung quite healthy; but the stomach, and the cardiac orifice in particular, were, as in the case I have just mentioned, in a state of intense inflammation. When hiccup is the result of inflammation of the cardiac orifice, you will also frequently observe that the patient complains of pain in the lower part of the chest, along the course DISEASES OF THE DIGESTIVE SYSTEM. 27 of the diaphragm. These are some of the relations of gastritis, their connection with which is proved by their being relieved by draughts of cold water, leeching, and every other means calculated to remove inflammation of the stomach. We come now to consider the state of the tongue. A vast deal of error and misconception prevails among British practitioners on this subject. Nothing is more common, than from the condition of the tongue to form an opinion as to the state of the alimentary canal. For instance, whether it is in a state of inflammation, whether there are sordes present or not, and whether it requires this or that medicine. All this is behind the actual state of medicine, and it is melancholy to think, what a vast quantity of mischief is done by those practitioners who take the tongue as the index of an inflammatory or non-inflammatory condition of the intestinal canal. The schools of Abernerthy and Brous- sais are wrong in stating that the tongue will point out the state of the digestive tube. The connection between the state of the tongue and that of the stomach, has been lately made the subject of extensive clinical investigation by M. .Andral; listen to his sentiments on this point. From the experience of a vast number of cases, he declares “ that there is no constant relation bet wen the state of the tongue and that of the stomach.” In the next place he states, “that there is no modification of the one corresponding with any special modification of the other.” “ Thirdly, the stomach may be found in a certain state after death, with various conditions of the tongue during life.” “Fourthly, we may have a diseased stomach with a healthful condition of the tongue, and diseased appearance of the tongue with a healthful state of the stomach.” These are facts of the greatest importance. Let us now refer to Louis. In giving an account of the gastritis which accompanies fever, he states that in many of the worst cases the appearance of the tongue was natural, in fact, that there was not the slightest relation between the tongue and the stomach. It is fair, however, to observe here, that both these pathologists drew their information only from cases of gastritis, occurring in fever. But it has also been frequently observed, that even in idiopathic cases there is a want of correspondence between the condition of the tongue and stomach, and we have seen several instances of this in the Meath Hospital. I believe we should be wiong in taking the tongue alone as our guide in the treatment of intestinal derangement, whether existing in the stomach or any other portion of the tube, and this I state as the conclusion which I have drawn from my own experience, in gastric and enteric inflammation. Yet how many will you see taking the tongue as the unerring index of various conditions of the digestive tube? hundreds and thousands. It is unquestionably true, that in certain cases of gastritis, particular morbid appearances, as redness, dry- ness, pointing, and a tremulous state of the tongue, are observed, but what 1 wish to impress on you is, that it is necessary that these 'phenomena should coincide with other symptoms. 1 do not wish 28 STOKES’S THEORY AND PRACTICE OF MEDICINE. you to believe, that the inspection of the tongue, or the knowledge derived from its appearance, is useless, particularly in cases of fever: the state of the tongue is never to be overlooked, but you should understand on what principle it is to be examined. You should examine the tongue not so much as a guide to the know- ledge of local disease, but as an index of the condition of the general system. For instance, if, during the course of a fever, the appearance of this organ changes and becomes more favourable, it is a sign that the whole disease has taken a favourable turn, and vice versa. This is the proper way to look at the tongue in fever, not as reflecting any particular state of the intestinal canal, but as being indicative of some modification of the whole economy. Let us now consider the sympathetic relations of the nervous and respiratory systems in gastritis. This is a very curious and interesting point in the study of gastric disease. I may mention here, that these relations are subject to considerable variety, and differ according to the peculiar predisposition of the individual. If a person of nervous habit gets gastritis, he will be very liable to have sympathetic affections of some part of the nervous system; but if he is a person with unsound lungs, the irritation will be transferred to the respiratory apparatus. Can we define these irri- tations ? I believe the best definition we can give of them is, that they are affections of some organ, which are the result of sympa- thy ; and that they are at first functional, but afterwards become organic. A person of nervous habit, labouring under gastritis, will frequently have his head sympathetically affected; he will com- plain of headache, more or less intense ; toss about and get no sleep ; still he has no actual disease of the brain. But let the cere- bral irritation go on, let the pain and uneasiness and watchfulness continue, and he will finally get arachnitis. So, too, with respect to the lung; the patient has hurried breathing and cough, without any of the stethoscopic signs of pulmonary disease; but if these symptoms continue for any length of time, or if the irritation be severe, he will get pneumonia or bronchitis. Observe the import- ance of this law with reference to treatment, because it shows you that you cannot always expect to remove sympathetic affections by attacking the original source of disease; for if functional de- rangement, produced by sympathetic irritation, has gone so far as to become organic, you must direct your attention to parts which have been secondarily engaged, as well as to those which are pri- marily affected. Every one is aware of the effects of particular states of the stomach on the brain, and of the influence which the brain exercises over the stomach. Most individuals know, that by grief or strong mental emotion the appetite is completely removed ; and that after a surfeit, or from taking bad and indigestible food, a person will get sick headache. If this happens every day under ordinary circumstances, and where the original affection is so slight that it does not interfere with the usual avocations of the patient, you can readily conceive how intense the sympathetic irritations may be in a case of violent gastritis. The headache is DISEASES OP THE DIGESTIVE SYSTEM. 29 frequently intense, the patient is extremely restless, there is consi- derable intolerance of light, delirium, tetanic spasms, and other symptoms characteristic of inflammation of the brain. There are numerous cases on record in which these symptoms were particu- larly noticed, and it was supposed that the brain was in a state of inflammation, but on dissection there was no disease found, except in the mucous membrane of the stomach. There are many cases, too, in which medical men, not aware of the extent of these rela- tions, looked upon the disease as a pure cerebral affection, and di- rected their whole attention to the brain. They certainly succeeded in modifying the apparent disease, but as they took no steps to remove its cause, the patients generally sunk from an unsuspected gastritis. There is one important law with respect to inflammation of the stomach, which perhaps may be fairly applied to all inflam- matory affections of the digestive tube. When inflammation of the stomach or any other portion of the intestinal canal has continued for some time, and when the disease has attained a certain degree of violence, the local symptoms may subside, and the gastritis or enteritis will be represented by disease of some other organ, by symptoms of an affection of the brain or its investments, or by symptoms of disease of the lining membrane or parenchymatous tissue of the lung. I shall endeavour to explain this. Here is a case taken from the Clinique Medicate of Andrei. “ A middle-aged man, four days before his entrance into the hos- pital, was seized with bilious vomiting, epigastric pain, and fever. (Here is a certain case of gastritis.) In about twenty-four hours after the invasion of these symptoms, he first perceived a difficulty in depressing the lower jaw, and a violent trismus was established, which continued for the two following days ; at the end of this time he entered the hospital in the following state :—trismus, the head drawn backwards and forcibly retained in this position by the muscles which are inserted into the occipital region ; rigidity of all the extremities ; abdomen hard as a board ; intellect perfect. Not- withstanding the trismus, the patient could articulate with sufficient distinctness to give the above account of his case. From the time when the first tetanic symptoms appeared the vomiting and epi- gastric pain ceased. He died on the evening of his admission. On dissection no appreciable alteration of structure was found in the brain or spinal marrow ; the meninges of the brain were very slightly vascular, but those of the spinal marrow pale. The whole surface of the stomach presented an intense red colour, which was at first concealed by a thick layer of mucosities. The remainder of the digestive tube was perfectly healthy, and the thoracic organs were natural.” This may be called a case of tetanus ; and it is a curious fact, that when the tetanic spasms came on, the vomiting and other symptoms of gastritis subsided. Now this is what I wish to direct your attention to. A man dies with symptoms of an affection of the brain, the head is opened after death, there is no trace of cerebral disease found, but the whole surface of the sto- mach is discovered to be in a state of intense inflammation. That 30 STOKES’S THEORY AND PRACTICE OF MEDICINE. the stomach was inflamed is proved by the vomiting and epigastric pain which existed during life, as well as by the vascularity which was revealed by dissection ; and there can be no doubt that this condition was the result of an intense inflammation, as there was no other cause to produce it. Last year, a patient was admitted into the Meath Hospital, labouring under violent maniacal excitement, his eyes blood-shot, and his aspect ferocious. He had thirst, a dry fissured tongue, a quick weak pulse, and constipated bowels. There was no epigas- tric tenderness, no vomiting, in fact, none of the prominent symp- toms of gastritis complained of. On the third day the belly was slightly tender and tympanitic. The cerebral symptoms increased so as to require the use of the strait waistcoat, and continued with violence until a short time before death, which occurred on the eighth day. On dissection there was no appearance of inflamma- tion found in the brain or its membranes, but there was a vast extent of disease in the digestive tube. The splenic extremity of the stomach presented several patches of vascularity, and its mu- cous coat was softened ; the lower half of the ileum, the caecum, and part of the ascending colon, were in a state of intense inflam- mation, and dotted all over with numberless ulcerations. You observe of what importance the knowledge of these facts will be to you in practice, and how much it should become the object of your study, since you will thereby be able to make the diagnosis of gastritis from the sympathetic relations, though the usual symptoms are more or less absent. Even in cases of this kind, in which the symptoms have subsided on the appearance of these sympathetic irritations, the judicious practitioner will not be diverted from directing his attention to the source of the original mischief; nor will he, because the local symptoms have disap- peared, conclude that the disease has therefore been removed from the stomach. Many examples of this apparent transition of dis- ease are to be seen in cases of children, in which an inflammation of the upper part of the digestive tube frequently similates hydro- cephalus, and where the headache, delirium, and intolerance of light, are completely removed by the application of leeches to the epigastrium. I have seen this occur many times, and would entreat your particular attention to it. I believe many children are lost from the want of correct notions on this subject on the part of their medical attendants. The phenomena present in such cases are certainly those which characterise hydrocephalus ; but you should always investigate them with care, and ascertain whether the disease has commenced with symptoms of inflamma- tion of the mucous membrane, of the stomach, or bowels ; and if you find that it has originated in this way, and that the cerebral symptoms have not gone too far, direct your treatment in the first place to the digestive tube. It is extraordinary how rapidly all the symptoms of apparent cerebral disease subside under this plan of treatment. I must mention here to you a very remarkable case of enteritis, which simulated local disease of the substance of the 31 PATHOLOGY AND TREATMENT OF GASTRITIS. brain. A girl who had received an injury was admitted into the Meath Hospital ; she was treated with purgative medicines, and was “ discharged cured /” In a few days afterwards she was re- admitted with pain in the head, and violent spasmodic contractions of the fore-arm, by which the fingers were bent so forcibly that the nails were driven into the hand. There was no thirst, vomit- ing, or abdominal tenderness. She died a few days after her admission; and on dissection the brain was found perfectly healthy, the viscera of the thorax were in the normal state, the stomach presented nothing remarkable, but the ileum was almost one sheet of deep and recent ulcers. The result of this case is important, also, in another point of view. You know that spasmodic contrac- tions of the upper extremtiy are believed by certain pathologists to point out an inflammatory softening of the optic thalamus, and its prolongations. Here we had the symptom, at all events, without the corresponding lesion. I shall reserve the subject of sympathetic irritations of the respi- ratory system until Wednesday, when I expect to be able to finish the pathology and treatment of gastritis. LECTURE IV. Gastritis—No one symptom decidedly indicative of the particular condition of any organ—Sympathetic irritation liable to terminate in organic disease—Sympathetic relations as connected with the viscera of the thorax—Treatment of simple acute gastritis—Antiphlogistic remedies—Purgative medicines injurious—Enemas and injections—Use of ice beneficial—Effervescing medicines hurtful. You recollect that at our last meeting I endeavoured to lay- before you some of the general facts connected with the pathology of gastritis, and showed you that the statement made by Broussais, that inflammation of the mucous membrane of the stomach is always accompanied by a similar affection of some part of the intestines, has not been confirmed by the investigations of more recent observers; but, on the contrary, that their experience goes to disprove, in various instances, the validity of this assertion. But, when I say that this statement has been disproved, it is only as taken in the general and extended sense. The fact of their fre- quent coexistence has been proved; the statement that they are always associated has been found incorrect. Another thing con- nected with this, which has been also established by repeated observation, is, that the cases in which they are commonly com- bined. are those in which a secondary affection of the mucous sur- face of the digestive tube comes on during the course of a fever; so that, if in fever a gastritis supervenes, you will commonly have enteritis ; or if the fever be complicated with enteric inflammation, the mucous surface of the stomach will partake in the diseased action. 32 STOKES’s THEORY AND PRACTICE OF MEDICINE. I have described some of the more prominent symptoms of gas- tritis, and directed your attention not only to the ordinary symp- toms, as mentioned in books, but also to others which have either been passed over, or slightly noticed, by authors ; as, for instance, dysphagia, oppression and sense of constriction about the prae- cordia, globus, pains relieved by cold and acid drinks, &c., and that obstinate hiccup, which, in cases where there is reason to suspect gastritis, marks inflammation of the cardiac orifice of the stomach. I stated that hiccup alone does not pixwe the existence of inflammation of the cardiac orifice of the stomach, unless where symptoms, indicative of gastric inflammation, prevail at the same time. I laid before you the actual state of the case with respect to the value and certainty of diagnosis, as derived from an inspection of the tongue; and showed you that no reliance can be placed on it, since it has been proved that we have the most opposite condi- tions of the digestive tubes, accompanied by a similar condition of the tongue; and that there is no peculiar modification of the one, corresponding exactly and constantly with any peculiar modifica- tion of the other. The conclusion to be deduced from these facts is, that in the treatment of inflammatory affections of the digestive tube, we are not authorised, and would frequently err, in taking the tongue alone as our guide in practice; and you may lay down this as a rule, and an important one:—if we look through the whole range of the history of medicine, we shall scarcely be able to point out any symptom which, taken singly, is decidedly indica- tive of any one particular condition of an organ. You will find that this proposition is not only extensive in its scope and relations, but also of extreme value in its application. You will commonly hear persons saying, this is such a disease, for this symptom is pre- sent, and that is such a disease, for such a symptom is extremely well marked. But there is no single symptom which points out, with certainty, any peculiar condition ; and to arrive at a just and well-grounded diagnosis, you must always take the whole group of existing phenomena, connect the lights which they collectively throw upon the case, and then make a cautious decision. It may be objected to this that there are particular signs; as, for instance, the stethoscopic, which point out distinctly particular states of organs. It is said that gargouillement is decidedly indicative of a phthisical cavity, that osgopho?iy points out a particular stage of pleuritic effusion, and that metallic tinkling is an unequivocal proof of pneumothorax. This, however, is not the fact; even in these cases you are not authorised to depend on any sign or symp- tom taken alone. If you ground your decision on any individual sign, you will very often fail in arriving at the truth. I showed you that the sympathetic irritation of gastritis varied according to the peculiar character of the disease, and the habit and degree of susceptibility of the patient; that, generally speak- ing, the more intense the disease is, the more numerous are its irritations ; but that, in all cases, they are considerably modified by predisposition (I use this term for want of a better), the sympa- PATHOLOGY AND TREATMENT OF GASTRITIS. 33 thetic irritation being1 reflected on the lungs in cases where these organs are naturally unsound, and on the brain, where the patients have a tendency to disease of that organ. I endeavoured, also, to impress on you the fact, that these irritations are at first functional; but when long continued, or marked by extreme severity, they are very apt to terminate in organic disease. I illustrated this point by several examples ; I shall give a few more of this kind before I enter on the treatment of gastritis. If a patient labouring under acute gastritis has a bad cough, if respiration be very much hurried, and the distress of the chest great, and that these symptoms are overlooked or neglected, you will find that the cough, which was at first only a result of func- tional disease, will at last point out an organic affection of the lung. Again ; let a patient, labouring under gastritis, have severe head- ache, restlessness, and irritation ; suffer these symptoms to go on and increase in violence, and the great probability is, that they will terminate in arachnitis. The obvious deduction from these facts is, that when a sympathetic irritation has existed for some time in a state of considerable intensity, it is very probable that there is more or less of organic derangement produced, and we are not to expect to be able to remove it by merely attacking the original seat of the disease. The last great rule which I endeavoured to impress upon you was, that where these sympathetic irritations, these affections of the nervous, respiratory, and circulating systems, were extremely well marked, the ordinary local symptoms were more or less want- ing, but that this does not by any means imply the subsidence of the original disease. This is a most important law in pathology. In my last lecture, I entered into a detail of the sympathetic irritations connected with the brain and other parts of the nervous system; to-day we shall consider the sympathetic relations, as con- nected with the viscera of the thorax. If you look to the cases of acute gastritis, mentioned in works on toxicology, you will find that in cases of gastritis, produced by swallowing corrosive poisons, the patient has often frequent hard cough, the breathing is at first hurried, then becomes protracted and laborious, and that death is generally ushered in by tracheal rattle. The same symptoms are observed in cases of acute idiopathic gastritis ; hurried breathing, extraordinary hard and almost laryngeal cough, sometimes occur- ing in paroxysms, sometimes constant. For the first few days it is, generally speaking, dry; as it progresses, there is more or less ex- pectoration. At first, it is the result of sympathy; there is as yet no organic affection of the respiratory system, and the disease is purely functional; still it is of importance, and entitled to your particular attention, because, in consequence of the apparent identity of the symptoms, it is often mistaken for disease of the substance of the lung, or its mucous lining. The existence of a gastritis is frequently overlooked ; the ordinary symptoms of pain in the region of the stomach, tenderness on pressure, and thirst, are overlooked, and the sympathetic relations alone are attended 34 STOKES’S THEORY AND PRACTICE OF MEDICINE. to. Observe what mischief may result from this error. The treatment of acute affections of the lining membrane, or paren- chymatous tissue of the lung, is very different from the treatment of a gastritis. In the one case bleeding is necessary; in the other, its efficacy may be doubtful, or the practice even dangerous. In one, tartar emetic is one of the best and most expeditious means of effecting a cure ; in the other, the use of antimonials has the worst effect. It will strike you that in such cases percussion and the stethoscope are of inestimable value. You are called to attend a patient in fever, you find he has cough, hurried breathing, and perhaps pain in the chest; from a consideration of the history of the case, and the primary symptoms, you have reason to think the case is one of gastritis, and you wish to know whether the symp- toms be purely sympathetic, or caused by organic disease of the lung. In such a case, a person without the knowledge of the stethoscope is completely helpless, and unable to decide the point. This, I assure you, is a very common case, and should be a strong inducement to the study of the stethoscope. What advantage does a knowledge of the stethoscope give ? It leads to the formation of an accurate diagnosis ; it points out either that there is no disease in the lung, or if there be, that it is not sufficient to account for the symptom, and therefore that, you should look for its cause in some other situation. You find a person with laboured and rapid breathing, perhaps fifty or sixty in a minute ; you are struck with the apparent lesion of the respiratory system, but on percussing the chest, and using the stethoscope, you find the respiration perfectly clear, or perhaps a slight bronchitis, insufficient to account for such violent symptoms. Where such phenomena are observed, you will often find that they are connected with a gastritis, particularly where there is fever, and the local signs of a gastric inflammation. I can tell you, from a most extensive experience, that in such cases you can inform the patient’s friends, that the most sudden and de- cided relief will be experienced from the use of iced water, and the application of leeches to the epigastrium. You can have hardly an idea of the rapidity with which all the symptoms of pulmonary irritation are removed by this practice. Cases of this extraordinary sympathetic irritation are very common in children, but you will also frequently meet with them in adults. I have been called to decide the question, whether a disease was pneumonia or gastritis, where there was a difference of opinion between two practitioners. Now, it is very easy to come to a proper decision in such cases. There is one point which you should always hold in view, and that is, the length of time the symptoms have lasted. If symptoms of pulmonary disease have been going on for four or five days, and, at the end of that time, you find that there is no perceptible organic disease of the lung, you may be certain that it is gastric irritation ; because if it were organic disease of the lung, it would have shown itself before that time, and could be detected by percussion or by the stethoscope. We have had many cases of these sympathetic irritations of the PATHOLOGY AND TREATMENT OF GASTRITIS. 35 lungs in the Meath Hospital, which recovered under the treatment for gastritis; and where the patients, by some excess or error in diet, brought on the pulmonary symptoms again, they were removed a second time by putting them on a low diet. Before I quit this subject, I wish to make one remark, by way of caution. When you have discovered the existence of those sympathetic irritations, you should not be thrown off your guard, and consider them only as functional affections. You should examine the next day and the day after, for you may find that in a very short space of time actual disease of the lung has taken place. You should be, therefore, watchful, and never omit making a daily examination; for if the sympathetic irritation be severe, it is very apt to run into actual organic disease. We now come to speak of the treatment of simple acute gastritis. Here there are three principal indications. One of these is to remove inflammation as speedily as possible. You cannot, as under other circumstances, leave this disease to nature; the organ affected is one of the utmost importance to life ; and if you do not cut it short at once, a typhoid state comes on, to which the ordinary and efficient means of antiphlogistic treatment are inapplicable. The first indication, then, is to cut short the inflammation as speedily as possible. The next thing is to prevent the introduction of any thing into the stomach which will excite the physiological action of that viscus. You are aware, that while the stomach is engaged in the process of digestion, its vascularity is very much increased, and that this, which in health is merely a physiological condition, is unaccompanied by any kind of danger. But in a state of disease it proves a source of violent excitement, and superadds very much to the existing inflammation. You must, therefore, be extremely cautious with respect to what enters your patient’s stomach, and carefully remove every thing capable of adding to the excitement which always attends gastritis. The third indica- tion in the treatment is to modify and remove the sympathetic or secondary irritations. Now I shall suppose that we have to treat a case of simple acute gastritis, not produced by the swallowing of corrosive poison, or indigestible food. Here we have a patient labouring under violent inflammation of one of the most important organs in the body; and the question is, are you to adopt the ordinary and usual mode of stopping inflammation by opening a vein in the arm 7 I must here state, that we are very much in want of a series of well- established facts to guide our practice on this point, and to inform us how far general bleeding is useful in acute inflammation of the stomach. At the present period, the question is by no means settled, and the practice is uncertain. I believe, however, that when we are called in at an early period of the disease, where the patient is young and robust, the stomach previously healthy, the fever high, and the pain great, we may have recourse to general bleeding with advantage; bearing this in mind, however, that you are not to expect to cut short the inflammation by the use of the 36 STOKES’S THEORY AND PRACTICE OF MEDICINE. lancet. Inflammations of the mucous membrane of the stomach and bowels, and perhaps of the lungs, are not to be overcome at once by the lancet; the only cases in which you can expect to cut short an inflammatory attack, are those in which the paren- chymatous tissue of an organ, or its serous membrane, is affected. This is a general and important law. You will often be able to cut short a hepatitis or a pneumonia by a single bleeding, but you will not by the same means be able to repress a bronchitis or an inflammation of the mucous membrane of the intestines. If you bleed in gastritis, bleed at an early period ; not too largely, or with the expectation of cutting short the inflammation, but in order to prepare your patient for the grand agent in effecting a cure— local bleeding. This is the principle on which you are to employ the lancet. In the treatment of gastritis there is nothing more useful, nothing more decidedly efficacious, than the free and repeated application of leeches, whether the case be idiopathic, or produced by the swallowing of a corrosive poison. In this treatment of acute gastritis, you will frequently see, perhaps, the most striking instances of the rapid and decided utility of medical treatment; you will see the vomiting subside almost immediately, the epigastric pain and tenderness disappear, the cough and headache relieved, the fever subside, and the tongue change, after the application of leeches. To remove the symptoms, the best and most effectual means are leeches ; and these must be applied again and again, according to the duration and obstinacy of the symptoms. Here I wish to make one remark of importance. From an opinion, very prevalent in former times, that pain and inflammation were insepa- rable, the older practitioners thought that when the pain ceased the inflammation also ceased; and hence many of our predecessors, and I fear some of our cotemporaries, never think of reapplying leeches, no matter what the existing symptoms may be, if pain has been relieved by the first application. Nothing is more erroneous than this practice. It frequently happens that the pain and epigas- tric tenderness are removed by the first application of leeches, but the breathing is still quick, the fever high, and the thirst ardent. So long as these symptoms remain, the inflammation of the stomach is still going on. The mere subsidence of pain or tender- ness of the epigastrium should never prevent us from resorting to the application of leeches. In leeching the belly for inflammation of the stomach or bowels, it is a common practice to apply a poultice over the leech bites, with the view of getting away as much blood as possible. I am not inclined to approve of this practice. The weight of a poultice is frequently troublesome, and the heat produced by it disagreeable ; the patients desire cold, and for this purpose they will often throw off their bed-clothes, feeling a degree of relief from exposing the epigastrium to a stream of cool air. Some practitioners have applied pounded ice over the stomach with good effects, as we see it frequently applied to the head with the same results in cases of encephalitis. Again : the PATHOLOGY AND TREATMENT OF GASTRITIS. 37 application of poultices causes an oozing hemorrhage, the amount of which it is impossible to calculate, which is often hard to be arrested, and which, in debilitated persons and children, has the effect of lessening the powers of life without removing the original disease. It is much better to leech again and again than to do this. Where there is not much epigastric tenderness, you may apply a cupping-glass over the leech bites with advantage, as you can get away as much blood as you choose, and the tendency to after-hemorrhage from the leech bites is diminished by the applica- tion of the cupping-glass. In very young subjects, the tendency to obstinate hemorrhage from leech bites is so great, that many practitioners are afraid to use leeches, and I believe some children have been sacrificed to this fear. The best mode of managing this is, if the leech bites cannot be stopped by the ordinary means (and in very young children they seldom can), to stop them at once by the application of caustic. Do not lose time in trying to arrest the flow of blood with flour, or lint, or sitcking plaster ; wipe the blood off the bite with a piece of soft dry lint, plunge into it a piece of lunar caustic, scraped to a point, give it a turn or two, and the whole thing is settled; and you can generally go away with the agreeable consciousness of having prevented all further danger, and without being uneasy lest your patient should bleed to death in your absence. With respect to the management of the bowels in acute gastritis, a few observations will suffice. You will always have to obviate the effects of constipation ; both in the acute and chronic forms of the disease there is always more or less constipation ; in fact, the same condition of the bowels is generally observed in both. Now, if you attempt to relieve this constipation in acute gastritis, by administering purgatives, you will most certainly do a vast deal of mischief. Nothing can exceed the irritability of the stomach in such cases; the mildest purgatives are instantly rejected, even cold water, or effervescing draughts are often not retained, and a single pill or powder is frequently thrown up the moment it is swallowed. Under such circumstances, it is plain that the administration of purgative medicine is totally out of the question. Even though the stomach should retain the purgative, you purchase its opera- tion at too dear a price; for it invariably proves a source of violent exacerbation, kindling fresh inflammation in an organ already too much excited. In this state of things, the best thing you can employ to remove constipation is a purgative enema, repeating it according to the urgency or necessity of the case. Where there is no inflammation in the lower part of the intestinal canal, you may employ injections of a strong and stimulating nature, with the view not merely of opening the bowels, but also of exercising a powerful revulsive action. I shall mention here an interesting fact, proving that stimulant injections have a decided revulsive effect; and that their influence extends not only to other portions of the intestinal tube, but also to distant parts of the system. In South America, where, from the heat of the climate, and the preva- 38 STOKES’S THEORY AND PRACTICE OF MEDICINE. lence of bilious affections, sick headache is a very common and distressing symptom, a common mode of cure is to throw up the rectum an extraordinary enema, composed of fresh capsicum, and other aromatic stimulants. The irritation which this produces acts as a very efficacious and speedy revulsive, causing the almost immediate removal of the cerebral symptoms. In those cases of gastritis, where not only purgatives, but even the mildest substances, are rejected, the plain common-sense rule is to give nothing. Where cold water is borne by the stomach, it may be taken in small quantities, as often as the patient requires it. Solid ice, too, may be given with decided benefit. There is a mistake which prevails with respect to the employment of ice in gastritis, which I wish to correct. Some persons objected to this use, and reason in this way:—persons who have taken a quantity of cold water, or ice, when heated by exercise, have been frequently attacked with gastritis and fever, and consequently the use of these substances must be attended with danger in case of gastric inflam- mation. This, however, is false reasoning; you need not be afraid to order your patient ice, ad libitum ; depend upon it, there is no danger in employing either ice or cold water in gastritis. There is nothing so grateful to the patient as ice. Let a quantity of it be broken into small pieces, about the size of a walnut; let your patient take one of these pieces, and, having held it in his mouth for a few moments to soften down its angles, let him swallow it whole. The effect produced by this on the inflamed surface of the stomach is exceedingly grateful, and the patient has scarcely swallowed one portion when he calls for another with avidity. It will be no harm if I should here mention to you a secret worth knowing. There are few things so good for that miserable sick- ness of the stomach, which some of you may have felt after a night’s jollification with a set of pleasant fellows, as a glass of ice ; Byron’s hock and soda-water are nothing to it. After the first violent symptoms of the disease have been sub- dued, I believe the very best thing which can be given is cold chicken broth. The point which we are always to keep in view is, to remove inflammation from the stomach, and this should regu- late the use of every thing taken into the stomach. I believe we might derive much advantage from anodyne injections in gastritis. I cannot say that I have ever employed them in such cases; but if I were to reason from their utility in other forms of abdominal inflammation, I should be induced to look upon them as entitled to some consideration. There is another point to which I will briefly advert. In the treatment of acute gastritis, there is nothing more commonly used than effervescing draughts ; yet I have frequently seen them produce distinct irritation of the stomach. In cases where gastric irritability is excessive, I would not advise you to give effervescing draughts, or if you do, watch their immediate effect; see how the first one has agreed with the stomach before you venture to give any more. Patients labouring under this dis- ease should be kept extremely quiet, as frequently a slight motion PATHOLOGY AND TREATMENT OF GASTRITIS. 39 brings back the vomiting. Every thing which is swallowed should be in small quantity; a large quantity of any substance frequently causes a return of the vomiting, by distending and irri- tating the stomach. One of the best things you can give, and the best way of giving it, is iced lemonade, giving a tablespoonful from time to time. The extremities, which are generally cold in cases of intestinal disease, should be swathed in warm flannel. I shall mention here a rule which should be carefully observed in the after treatment. A patient has recovered from the violent symptoms of the disease ; the fever, thirst, pain, epigastric tender- ness, and sympathetic affections, have subsided ; but he still is con- fined to bed, and in a state of great debility. Some patients, under these circumstances, have been unfortunately lost by allowing them to sit up in bed, or on the night chair. The nurse will some- times, through ignorance, suffer a patient, thus enfeebled, to risk his life by sitting up in bed ; sometimes, during the course of the night, she is overcome by sleep ; the patient has a call to empty his bowels : and not wishing to disturb her, attempts to get up, and is found, in some time afterwards, sitting on the night chair quite dead. This is an unfortunate termination for the physician as well as the patient. A German author, Hoffmann, has written a treatise on the danger of the erect position after acute diseases; and in the course of the work, which is a very interesting one, he cites numerous instances of its bad effects. Not very long since, a patient was lost in the Meath Hospital, by the nurse allowing him to sit up after a severe attack of enteritis. Such, also, was the melancholy cause of death in the case of the late Mr. Hewson, one of my best and earliest friends. He got a severe attack, which was subdued with difficulty, and his convalescence was doubtful and protracted. One night, in the absence of his attendant, he got up for the purpose of emptying his bowels, and was found, some time afterwards, on the night chair, nearly dead. He was immediately brought back to bed, and the necessary means employed to relieve him, but without much benefit, for he never recovered the effect produced on his debilitated frame. 40 STOKES’S THEORY AND PRACTICE OF MEDICINE. LECTURE V. Pathology and treatment of gastritis—Application of blisters—Emetics can be seldom used in acute gastritis—Hasmatemesis and delirium tremens complicated with gas- tritis—Treatment of these affections—Dyspepsia, or chronic gastritis—Hypochon- driasis—Termination of chronic gastritis. There is one point connected with the treatment of gastritis which I have not yet touched upon—the use of blisters; and as this is the first time I have spoken of them, I shall make a few remarks on their general application. It is a great error to think that blistering is a matter of course in inflammatory diseases, or that the proper period for their applica- tion should not be carefully marked. It is a common idea, that if a blister does no good it will do no harm; that it is probable some benefit may result from its employment, and that you may try it at ail events. I need not tell you that all this is wrong, and that we must be guided by exact principles in this as well as in every other part of practical medicine. I am afraid there is a great deal of loose reasoning and empirical practice connected with this sub- ject, even at the present day. Here is the general rule by which you should be invariably guided. No matter what kind of disease you have to deal with, if it be inflammatory, blistering in the early stage of it is decidedly improper. I might amplify this rule, and say, that if the disease be inflammatory and in its early stage, or if, under such circumstances, the symptoms require the general or local abstraction of blood, blisters cannot be used with propriety. The truth is, that many persons take a very limited view of this subject; they look upon blisters as merely revulsive agents, which, by their action on the surface, have the property of diminishing visceral inflammation. This I am willing to allow is true to a certain extent, but there is abundant evidence to prove, that blis- ters have sometimes a direct stimulant effect on the suffering organ. That this occasionally occurs has been established by many facts in medicine; and I have not the slightest doubt that the application of a blister over an organ in a state of high inflam- matory excitement will certainly be productive of injurious conse- quences. But if you apply them at the period when stimulation is admissible and useful, (and there will always be such a period in every inflammation,) you then act on just principles, and will ge- nerally have the satisfaction of finding your practice successful. The greatest empiricism is sometimes practised in the application of blisters to the head in acute inflammation of the brain. You will see, in Mr. Porter’s admirable work on the Pathology of the Larynx, how strongly he is opposed to the early use of blisters in acute laryngitis. Dr. Cheyne, also, may, among many others, be quoted in support of this doctrine. If there is one system more than another likely to be injured by early blistering, it is the digestive. Broussais says that blisters 41 PATHOLOGY AND TREATMENT OF GASTRITTS. should not be applied in any of the stages of acute gastro-enteritis, and that in the early stage their application is the very height of malpractice. I do not go so far as to say that they should not be applied in any period of the disease, for when the skin is cool, the pulse lessened, and the local inflammation so far reduced as not to require the abstraction of any more blood, I think you may employ them with very considerable advantage. I shall again return to the subject of blisters ; and will for the present merely remark, that blistering is almost always mismanaged, in consequence of persons who apply them being ignorant of their stimulating effects on organs. They generally allow them to remain on too long, and the consequence of this is often violent excitement of the organ over which they are applied, great constitutional irritation, stran- gury, and bad sores. The best mode of using them is to direct the person who prepares the blister to cover it with a piece of silver-paper before it is applied, and having put it on with the paper next the skin, to let it remain until a decided sense of smart- ing is produced, when it should be immediately removed. By adopting this plan, you will save yourself and your patient a great deal of inconvenience ; you will have no strangury, stimulation of the whole economy, or excessive local irritation, and the inflamed surface will heal kindly. The mode (too often practised) of apply- ing a blister sprinkled all over with an additional quantity of pow- dered cantharides, and leaving it on for twelve, twenty-four, or even thirty-six hours, particularly in the case of females, is nothing- better than horse doctoring. During a seven years’ experience in the hospital at Tours, Bretonneau, by attending to this principle, never had a case followed by these troublesome symptoms, and yet he never failed in producing the necessary degree of counter- irritation. The active principle of cantharides, being soluble in oil. exudes through the silver-paper in sufficient quantity to pro- duce the necessary effect on the skin, without exposing the patient to the risk of having too much irritation excited by the direct ap- plication of the blistering plaster to the cutaneous surface. With respect to emetics, I need not tell you that they can be very seldom used in acute gastritis, and that all your efforts should be directed to obviate and remove vomiting. But are we to interdict their use altogether? There are some few cases where we are compelled to use them; as, for instance, in cases of acute gastritis caused by swallowing corrosive poison, or by the irritation of indi- gestible food remaining in the stomach. The first step to be taken in a case of corrosive poisoning, is to evacuate the stomach. In the same way, when you are called to treat a case of gastritis produced by indigestible aliment, you must commence by giving an emetic. But even here the emetic is admissible only in the early period; and you should never trust to its operation for removing the gas- tritis altogether, unaided by other therapeutic means ; nor are you to conclude that because you have produced vomiting you have succeeded in curing the disease. The same principles apply to the use of purgatives in enteritis as to emetics in gastric inflammation; St. 4 42 STOKES’S THEORY AND PRACTICE OF MEDICINE. we should never have recourse to them except where inflammation is kindled and kept up by the presence of irritating matter. There are two cases in which certain affections are complicated with an acute gastritis; and as these complications are not suffi- ciently known, and have been scarcely noticed by sytematic writers on gastritis, I am anxious to draw your particular attention to them. One of these is hcematemesis, the other that disease which has been termed delirium tremens. There are cases of vomiting of blood, which are little more than acute gastritis, in which there is a copious secretion of blood from the mucous surface of the sto- mach. Vomiting of blood may arise from various causes. It may be vicarious, as in the case of females, where the menstrual flux is suppressed ; it may be accidental, as from the rupture of a blood- vessel ; or it may be caused by mechanical obstruction to the circulation, either in the liver, spleen, heart, or lungs. But there is a species of gastritis, in which there is a copious vomiting of blood ; or there is an hsematemesis, of which the cause is gastric irritation. IIow are you to recognise this form of the disease?— The patient is vomiting blood; but then he has fever, hot skin, and excited pulse. Again, you will see some peculiar modification of the tongue; you will find ardent thirst and longing for cold drinks; you will observe fulness and tenderness of the epigastrium; you may have severe local pain ; finally, you will have all these symptoms occurring in a person who, previously to the attack, exhibited nothing capable of accounting for the heematemesis. Here, then, we have an haemorrhagic gastritis, very little known, and too often improperly treated. The ordinary practice, in such cases, is to give astringents. Astringents are very good and useful where they are clearly indicated; but there are many forms of disease where their routine employment is productive of a great deal of mischief; and I believe lives are sometimes lost by looking upon this affection as a simple haematemesis, and by practitioners contenting themselves with the use of astringents. But where you have the symptoms of this form of gastric irritation present, where, in addition to the vomiting of blood, you have fever, and thirst, and hot skin, and pain, and epigastric tenderness, you may be sure that it is a gastritis, and that the best treatment is leeches, iced water, and the other means recommended in the treatment of gastric inflammation. It may happen that, under this treatment, the vomit- ing of blood will not entirely subside ; but the pain, the thirst, the fever, and epigastric tenderness will subside, and then you can with propriety give astringents. The best thing you can do in the commencement is to leech freely, give iced lemonade, and cold water ; prohibit every thing purgative, stimulant, or astringent; and then, when you have reduced inflammation, if the haematemesis continues, have recourse to astringents. A few words now with respect to the other complication—delirium tremens. You have all seen cases of delirium tremens, but you are not, perhaps, aware that it arises under two opposite classes of causes. In some cases, a patient who is in the habit of taking PATHOLOGY AND TREATMENT OF GASTRITIS. 43 wine or spirituous liquor every day in considerable quantities, meets with an accident or gets an attack of fever. He is confined to bed, put on an antiphlogistic diet, and in place of wine or whis- key punch gets whey and barley-water. An attack of delirium tremens comes on, and symptoms of high cerebral excitement appear. Another person, not in the habit of frequent intoxication, takes to what is called a fit of drinking, and is attacked with de- lirium tremens. In the first case the delirium arises from a want of the customary stimulus, in the second from excess. In each the cause of the disease is different; and, consequently, with this view of the subject, it would be a manifest departure from sound prac- tice to treat both cases in the same way. Yet, I believe, this error is frequently committed, even by persons whose authority is high in the medical world, and is part of a system not yet exploded— the system of 'prescribing for names and not for things. The patient is treated for a disease which has been called delirium tre- mens, the present symptoms are only attended to, and the cause and origin of the affection are overlooked. What are the true principles of treatment ?—In the first variety, where the delirium is produced by a want of the customary stimulus, there is no doubt that patients have been cured by the administration of the usual stimulants, by giving them wine, brandy, and opium. Indeed, this seems to be the best mode of treating this form of the disease. But is it proper or admissible in the second variety, where the delirium is caused by an occasional excess in the use of ardent spirits ?— Certainly not. Yet what do we find to be the ordinary practice in hospitals when a patient is admitted under such circumstances?— A man, who has been attacked by delirium tremens after a violent debauch, is ordered a quantity of porter, wine, brandy, and opium; and the worse he gets, the more is the quantity of stimulants in- creased. Now this practice seems to me as ridiculous as the old principle of treating a case of hydrophobia with a hair of the dog that bit. Let us consider what the state of the case is:—A large quantity of stimulant liquors have been taken into the stomach, the mucous surface of that organ is in a state of intense irritation, the brain and nervous system are in a highly excited condition from the absorption of alcohol, or in consequence of the excessive sym- pathetic stimulation to which they have been subjected. Are we to continue this stimulation ?—I think not. What would be the obvious and natural result ?—Increased gastric irritation, encepha- litis, or inflammation of the membranes of the brain. The super- vention of inflammatory disease of the brain in delirium tremens is not understood by many practitioners, and they go on administer- ing stimulant after stimulant, totally unconscious that they are bringing on decided cerebral disease. I have witnessed the dissec- tions of a great many persons who died of delirium tremens, and one of the most common results of the dissection was, the discovery of unequivocal marks of inflammation in the brain and stomach. Broussais considers all such cases as merely examples of gastritis, and ridicules British practitioners for inventing a “ new disease f 44 STOKES’S THEORY AND PRACTICE OP MEDICINE. but in this he is certainly wrong, for there have been several cases in which no distinct marks of gastric inflammation could be dis- covered. In all cases, however, where the delirium supervenes on an excessive debauch, there is more or less of gastritis; and though it may occasionally happen, that a patient under such circumstances may recover under the stimulant treatment, yet I am convinced that the physician will very frequently do harm by adopting it. This complication of delirium tremens with gastritis is also exceedingly curious in another point of view, as it illustrates how completely the local symptoms are placed in abeyance, and, as it were, lost during the prevalence of strong sympathetic irritation. The patient’s belly will not be tender ; the tongue may not be red; the symptoms present may be indicative of a mere cerebral affec- tion, and yet intense gastric inflammation may be going on all the time, and all the appearance of cerebral disease be quickly removed by treatment calculated to subdue a gastritis. Is this all theory? No ; for we have practised on this principle with the most extra- ordinary success in the Meath Hospital. We have seen cases of violent outrageous delirium subside under the application of leeches to the epigastrium, and iced water, without a single drop of lauda- num. I beg of you, if you meet with any cases of delirium tremens under such circumstances, to make trial of this mode of treatment, and record its effects, for it is important that they should be more extensively known. I have seen the whole train of morbid pheno- mena, the delirium, the sleeplessness, the excessive nervous agita- tion, all vanish under the application of leeches to the epigastrium. In some cases where after the sleeplessness and delirium were re- moved by this practice, and the tremours alone remained, we have again applied leeches to the epigastrium, and. succeeded in removing the tremours also. On the other hand, where a stimulant plan of treatment was employed, and the patients died, we have most com- monly found inflammation in two places, in the stomach, or in the brain or its membranes. The rule, then, is this—in a case of de- lirium tremens from the want of a customary stimulus, use the stimulant and opiate treatment; but when it comes on after an occa- sional violent debauch, such remedies must be extremely improper. Adopt here every thing calculated to remove gastric irritation. We have facts to show that most decided advantage may arise, from the application of leeches, even where the symptoms of gastritis are absent. We come now to consider chronic gastritis, an extremely in- teresting disease, whether we look upon it with reference to its importance, its frequency, or its Protean character. It is commonly called dyspepsia, and this term, loose and unlimited in its accepta- tion, often proves a stumbling block to the student in medicine. Dyspepsia, you know, means difficult digestion, a circumstance which may depend on many causes, but perhaps on none more frequently than upon chronic gastritis. In the great majority of dyspeptic cases, the exciting cause has been over stimulation of the PATHOLOGY AND TREATMENT OF GASTRITIS. 45 stomach, either from the constant excess in strong highly seasoned meats, or indulging in the use of exciting liquors. Persons who feed grossly and drink deeply, are generally the subjects of dys- pepsia ; by constantly stimulating the stomach they produce an inflammatory condition of that organ. Long continued functional lesion will eventually produce more or less organic disease; and you will find that in most cases of old dyspepsia there is more or less gastritis. But let us go farther, and enquire whether those views are borne out by the ordinary treatment of dyspeptic cases. When you open a book on the practice of physic, and turn to the article dyspepsia, one of the first things which strikes you is the vast number of cures for indigestion. The more incurable a disease is, and the less we know of its treatment, the more numerous is the list of remedies, and the more empirical is its treatment. Now the circumstance of having a great variety of u cures’’ for a disease, is a strong proof, either that there is no real remedy for it, or that its nature is very little understood. A patient afflicted with dys- pepsia will generally run through a variety of treatment, he will be ordered bark by one practitioner, mercury by another, purga- tives by a third; in fact, he will be subjected to every form of treat- ment. Now all this is proof positive that the disease is not suffi- ciently understood. What does pathology teach in such cases? In almost every instance where patients have died with symptoms of dyspepsia, pathological anatomy proves the stomach to be in a state of demonstrable disease. It appears, therefore, that, whether we look to the uncertainty and vacillations of treatment, or the results of anatomical examination, the case is still the same ; and that, where dyspepsia has been of considerable duration, the chance is that there is more or less of organic disease, and that, if we pre- scribe for dyspepsia neglecting this, we are very likely to do mischief. I do not wish you to believe that every case of dyspepsia is a case of gastritis. This opinion has brought disgrace on the school of Broussais. His disciples went too far; for whether the gastric derangement depended on nervous irritation, or anaemia, or disease of the liver, or mental emotion, they prescribed leeches and water diet, and thus very often brought on the disease they sought to cure. We may have functional disease, independent of structural lesion, in the stomach, as well as in any other organ ; it is no un- usual circumstance, and the practical physician meets with it every day. A great deal of confusion, however, arises from the similarity of the symptoms. I remember an accomplished friend of mine getting into disgrace with one of the members of a board of exa- miners on this subject. He was asked to tell the difference between the symptoms of chronic gastritis and dyspepsia, and in reply stated that he could not. For this he was nearly rejected; but, I believe, on a candid review of the circumstances, you will agree with me, that he knew more of the matter than the learned professor. In ninety-nine cases out of a hundred of chronic gastritis there is no fever, scarcely any thirst, often no fixed local pain, and this leads persons away from any idea of the existence of an inflammatory 46 STOKES’S THEORY AND PRACTICE OF MEDICINE. condition of the stomach. What are the symptoms of a chronic gastritis ? pain of occasional occurrence, flatulence, acidity, swell- ing of the stomach, fetid eructations, sensation of heat and weight about the epigastrium, and perhaps vomiting. Well, these are also the symptoms of dyspepsia, whether it be accompanied by inflam- mation or not. How then, when called to a case of this kind, are you to determine the point ? I must mention to you here, that it is often hard to do this with certainty. There are two circum- stances, however, which you should always bear in mind, as they will afford you considerable assistance in coming to a correct diag- nosis ; first, the length of time which the disease has lasted ; secondly, the result of the treatment which has been employed. You will find, that where the disease is a chronic gastritis, that it has been of some duration, that it has come on in an insidious manner, and that it has been exasperated by the ordinary treat- ment for dyspepsia. Many persons think, that if you give a patient medicine, without regulating his diet or issuing a prohibition against full meals, that you can cure him, and that, as he has no fever, and can go about his usual business, there is no necessity for antiphlogis- tic regimen. But as the disease goes on, he complains of pain in the stomach during the process of digestion, feels uneasy after dinner, there is an unpleasant degree of fulness about the epigastrium, he also experiences a variety of disagreeable symptoms, sometimes being annoyed with pain in the chest, sometimes he says he feels it in the region of the heart, and sometimes about the cartilages of the eighth and ninth ribs. These symptoms subside after the process of digestion is completed, but during its continuance they harass the patient. Yery often relief is obtained by vomiting, and hence some persons are in the habit of throwing up their food for the purpose of relieving themselves, and consequently can have no benefit by it. In some cases digestion goes on until the food seems to reach a particular point, and then an acute feeling of pain is experienced. In these cases the gastritis is generally circum- scribed, and is likely to terminate in circumscribed ulceration. Various fluids are rejected from the stomach during the course of a gastritis; sometimes acid, sometimes alkaline, sometimes insipid and sweet, sometimes bitter and bilious. There is generally a degree of fulness about the stomach, and the epigastrium is tender on pressure, but no decided tumour, either of the pylorus, liver, or spleen, although the epigastrium presented that appearance of fulness and tension termed by the French “renitenceThe bowels, too, are constipated, and this is a matter worthy of your attention, for it sometimes unfortunately happens that the practitioner, mistaking the gastritis for simple constipation, goes on prescribing purgative after purgative, until the patient gets incurable disease of the stomach. I know a case of a lady who gets one stool a week by taking eight drops of croton oil. Some years ago she was in the enjoyment of excellent health; her bowels happened to get confined, and she was treated by a systematic practitioner with continued purgatives; her bowels are now completely torpid, except when they are PATHOLOGY AND TREATMENT OF GASTRITIS. 47 subjected to this unnatural stimulus. There are thousands of persons treated in this way, because practitioners look to conse- quences and not to causes. There is one remarkable difference between acute and chronic gastritis, which deserves your attentive consideration, as it exem- plifies a law applicable to all viscera under similar circumstances, and this is, that the sympathetic irritations are not so frequent or so distinct in chronic inflammation as in the acute form, and hence, in a case of chronic gastritis we almost never have fever, and the affections of the nervous respiratory or circulating systems are by no means so well marked. It may even go on to actual disorganis- ation of the stomach, and yet the patient will not complain of any particular symptom during its whole progress, which yon could set down as depending exclusively on the sympathetic irritation of gastritis. Some of these cases, called dyspeptic phthisis, by Dr. W. Philip, are most probably examples of the sympathetic irritation of the lungs from chronic gastritis. Another case, respecting which much error prevails, is what has been called hypochondriasis. Persons labouring under these affections are condemned to run the gantlet of every mode of treatment; sometimes (and fortunately for themselves) they are sent to travel, sometimes they are treated with musk and antispasmodics, then with the mineral acids, then with purgatives and mercurials, and lastly with bark, nitrate of silver, and stimulants. They go about like spectres from one practitioner to another, trying remedy after remedy, alternately sanguine with hope or saddened by disappointment, until at last they die, and, to the astonishment of all the doctors, the only disease found, on dissection, is inflammation and thickening of the mucous surface of the stomach. A condition, which, under these circumstances, it was difficult to say whether it was the original disease, or produced by “ fair trials'’ of a number of powerful agents. Hypochondriasis is not always gastritis; but it is now found that, in many cases, it commences and terminates with disease in the upper portion of the digestive tube and the assisting viscera. This you must always bear in mind. Chronic gastritis terminates in various ways. Sometimes the inflammation is limited to a particular spot of the stomach, and here we frequently discover circumscribed ulcerations. In very bad cases these ulcers go on perforating the various coats of the stomach, until at last the contents of that organ escape into the serous cavity of the abdomen, and the patient rapidly sinks under a fatal peritonitis. It does not follow however, that, in all cases of perforation, the contents of the stomach get into the peritoneum, causing death. Very often adhesions are formed, and the base of the ulcer is the serous covering of some other portion of the diges- tive system, or a false passage may be formed into the colon. One of the most common terminations of a chronic gastritis is. that the inflammation extends to other viscera; the patient gets disease of the liver, spleen, peritoneum, or lungs, and sinks under a compli- cation of disorders. It was somewhat in this way that Napoleon 48 STOKES’S THEORY AND PRACTICE OF MEDICINE. died. He laboured for a considerable time under chronic disease of the stomach, which seems to have been overlooked by his medi- cal attendants, and this terminated in the extension of disease to various other organs. LECTURE YI. Treatment of chronic gastritis—Frequent excitement of the vascular system necessary to the performance of the functions of the stomach—Local bleeding—Regimen— Counter-irritation over the stomach—Treatment of Broussais—Use of vegetable tonics—Oxide of bismuth—Acetate of morphia. I shall begin to-day with the treatment of chronic gastritis, and I beg of you to bear in mind what I mentioned at my last lecture, that this disease, in its true and pathological meaning, is not suffi- ciently recognised. In general, it gets some wrong name or other; and as many practitioners are in the habit of prescribing for names, it generally meets with wrong treatment. It is called every thing but what it is, and its remedies are as numerous and as various as its appellations. By some, it is called dyspepsia, and is treated with bitters, astringents, and stimulants; by others, it is termed constipation, and treated with purgatives ; the school of Abernethy look upon it as an alfection of the liver, and prescribe blue pill and black draught; others give it the name of hypochondriasis, and exhaust the whole catalogue of nervous and anti-dyspeptic medi- cines in attemping its removal; in fact, it is called every thing but what it is, and the result is an unsteady and mischievous empiricism. You will recollect a fact, to which I alluded in my last lecture, that the physiological condition of the stomach requires that it should be subject to frequent excitements of its vascular tissue, and that this increased vascularity being the consequence of a natural process, digestion is, generally speaking, exempt from any kind of danger. If the brain or lungs were to experience an equal increase of vascularity, sensibility, and excitement, the consequence would he dangerous, or perhaps fatal, and we should have pulmonary and cerebral diseases produced. But though the stomach enjoys such a remarkable exemption from the liability to acute inflamma- tion, under circumstances of repeated vascular excitement, yet the slow, insidious, chronic gastritis, is an exceedingly common affec- tion. I feel convinced that many persons die of it, or of the exten- sive class of fatal diseases which it frequently induces. But I rejoice to say, that we have good reason to hope that the progres- sive amelioration of medical science will materially diminish the amount of human suffering from this cause. As physiological medicine advances, the number of those who die of unrecognised chronic visceral disease will be less and less, because diagnosis TREATMENT OF CHRONIC GASTRITIS. 49 will become more extended and certain, and practice more simple and successful. The first thing you should do, when called to treat a case of dyspepsia, is to ascertain whether it be a purely nervous disease, or a chronic gastritis. The majority of practitioners give them- selves no trouble about this matter, not recognising the fact, that of the number of dyspeptic persons who seek for medical advice, a considerable proportion are really labouring under a chronic gas- tritis, and forgetting, that, in consequence of long-continued func- tional injury, what was at first but a mere nervous derangement may afterwards become complicated with organic disease. You must also bear in mind, that the stomach is perhaps placed under more unfavourable circumstances for bringing about a cure than any other organ, because the life of the individual demands that the stomach, though in a state of inflammation, should still continue to perform its functions. In treating diseases of other organs, you will have the advantage of a comparative state of rest; but, in a case of the stomach, if you wish to preserve life, you cannot, pro- hibit nutriment, and, consequently, you must run the risk of keep- ing up these periodic vascularities which its condition requires, which, though harmless in health, become a source of evil when the stomach is diseased. The obvious deduction from this is, that the cure of chronic gastritis depends as much upon regimen as upon medical treatment, and particularly where the symptoms have arisen from long-continued excitement, as in the case of persons who live highly. Here the treatment chiefly depends on regulating the diet, and if your patient has sense enough to live sparingly for a few weeks or months, you may be able to effect a cure without other treatment. The great error is, that most prac- titioners attempt to cure the disease by specifics, and when these fail, they then go to the symptomatic treatment, prescribing some- times for acidity, sometimes for nausea, sometimes for flatulence, sometimes for constipation, or “the liver,” or debility. You should be careful in the examination of such cases, and should try to ascertain whether these symptoms may not depend upon inflammation of the stomach ; for as long as the patient is in this state, the less you have recourse to symptomatic or specific treatment the better. It is hard to mention one single medicine which, in this state, will not prove stimulant, and if the stomach be unfit for stimulants, it must be unfit for the generality of medi- cines. There are numbers of cases of persons labouring under chronic gastritis, which have been cured by strict regulation of diet, and by avoiding every article of food requiring strong diges- tive powers. We find that articles of diet vary very much in this respect; some are digested with ease, some with pain. We might express this otherwise, by saying, that some require very little excitement of the stomach, and others very great vascular excite- ment. Patients, in this irritable state of stomach, can scarcely bear any kind of ingesta; and when you consider the great vascu- larity, thickening of the mucous membrane, and tendency to 50 STOKES’S THEORY AND PRACTICE OP MEDICINE. organic disease, you will be induced to think that every thing entering the stomach should be of the mildest kind, and not requiring any powerful determination of blood to that organ. If you continually prescribe for symptoms, neglecting or over- looking the real nature of the disease, giving arsenic to excite the system, and iron to remove anaemia, and bitter tonics to improve the appetite, and alkaline remedies for acidity, and carminatives to expel flatus, you will do no good; you may chance to give relief to-day, and find your patient worse to-morrow ; and at last he will die, and you may be disgraced. On opening the stomach, after death, you are astonished to find extensive ulceration, or, perhaps, cancerous disease. Yery often, in such cases, practitioners say that it is cancerous disease, and that no good can be done. But the thing is to be able to know, when you are called to a case, whether it is a case of mere nervous dyspepsia, or chronic inflam- mation of the stomach. Some of the best pathologists think that most of the cancerous affections of the stomach are, in the begin- ning, only chronic inflammations of that organ. I believe we have not yet in this country adopted the plan of moderate application of leeches to the epigastrium in cases of chronic gastritis. I have seen, in many cases, great benefit result from the repeated application of a small number of leeches to the epigastrium, at intervals of two or three days. Here is a point which you will find very useful in practice. You will meet with cases which have lasted for a long time; cases where there is strong evidence of organic disease, and which have resisted the ordinary dyspeptic treatment. You will be called frequently to treat these three different cases:—where the disease has been of long duration ; where there is distinct evidence of organic disease ; and where the disease has resisted the ordinary dyspeptic treat- ment. Here is a case of a patient labouring under what is called indigestion, and which has resisted the stimulant, and tonic, and purgative treatment. Here is one fact. In the next place, the disease is chronic, and the probability is that there is inflamma- tion, and consequently that there is chronic gastritis. Now if, in such a case, you omit all medicine by the mouth, apply leeches to the epigastrium, keep the bowels open by injections, and regulate the diet, you will often do a vast deal of good. I have seen, under this treatment, the tongue clean, the pain and tenderness of the epigastrium subside, the acidity, thirst, nausea, and flatulence, removed, the power of digestion restored, and all the symptoms for which alkalies, and acids, and tonics, and purgatives, were pre- scribed, vanish under treatment calculated to remove chronic inflammation of the stomach. What is next in importance to regulated regimen and local bleeding? A careful attention to the bowels, which, in chronic gastritis, are generally constipated, and this has a tendency to keep up disease in the upper part of the digestive tube. Is this to be obviated by introducing purgative medicine into the stomach? No. If you introduce strong purgative medicine by the mouth, TREATMENT OF CHRONIC GASTRITIS. 51 you will do a great deal of mischief. You must open the bowels by enemata, or, if you give medicine by the mouth, by the mildest laxatives in a state of great dilution. A little castor-oil, given every third or fourth day, or a little rhubarb, with some of the neutral salts, will answer in most cases. The diet, too, can be managed, so as to have a gently laxative effect. The use of injections is, however, what I principally rely on. I have seen many cases of gastritis cured by the total omission of all medicine by the mouth, by giving up every article of food which disagreed with the stomach, and by the use of warm water enemata. I have seen this treatment relieve and cure persons whose sufferings had lasted for years previous to its employment, and who had been considered by many practitioners to labour under organic disease of an incurable nature. It is important that you should bear this in mind. The old purgative and mercurial treatment of gastritis, I am happy to say, is rapidly declining; and British practitioners are now convinced that they cannot cure every form of dyspepsia by the old mode of treatment. I do not deny that many diseases of the digestive tube may be benefited by the mild use of mercury and laxatives, but I think I have every reasonable and scientific practitioner with me in condemning the unscientific routine prac- tice, which was followed by those who took the writings of Aber- nethy and Hamilton for their guide. I do not say that, where cases of gastric inflammation, treated after the plan of Mr. Aber- nethy, have proved fatal, the medicines have destroyed life; I merely assert that the patients died of inflammation, over which these medicines had no control; and the error lay in mistaking and overlooking the actual disease, as much as in its maltreatment. You will find some practitioners (they are becoming fewer in number every day), who seem to have but two ideas, the one a purgative, the other a pot full of faeces; but the connecting link— the gastro-enteric mucous membrane—that vast expansion, so complicated, so delicate, so important, seems to be totally forgotten. But practitioners are now beginning to see that purgatives are not to be employed empirically ; that they should be administered in many cases with great caution, and with a due attention to the actual condition of the alimentary canal, and that they have been a source of great abuse in the medical practice of these countries. Next to leeching, and a proper regulation of the bowels, is the employment of gentle and long-continued counter-irritation over the stomach. This may be effected by the repeated application of small blisters, or by the use of tartar emetic ointment. I have been in the habit of impressing upon the class, that the tartar emetic ointment used in these countries is too strong, the conse- quence of which is an eruption of large pustules, which are exces- sively painful, and often accompanied with such disturbance of the constitution as amounts to symptomatic fever. In fact, tartar emetic ointment of the ordinary strength produces so much irrita- tion, that few patients will submit to it long. The form which I recommend you to employ is the following:—Take seven drachms 52 STOKES’S THEORY AND PRACTICE OF MEDICINE. of prepared lard, and, instead of a drachm of tartar emetic, which is the usual quantity, take half a drachm, directing, in your pre- scription (this is a point of importance), that it be reduced to an impalpable powder ; and you may add to it what will increase its action, one drachm of mercurial ointment. This produces a crop of small pustules, which give but little pain and are easily borne; and the counter-irritation may be kept up in this way for a con- siderable time, by stopping, for a few days, until the eruption fades away, and then renewing the friction. I have often seen the utility of this remedy exemplified in cases of chronic gastritis, where the symptoms of gastric irritation, which had subsided under the employment of friction with tartar emetic ointment, returned when it was left off, and again vanished when it was resumed. The case of the celebrated anatomist, Beclard, furnishes a very remark- able proof of the value of a well-regulated diet and repeated counter-irritation in the treatment of this disease. While he was engaged in the ardent prosecution of his professional studies he got an affection of the stomach, which he considered to be a chronic gastritis, and immediately put himself under a strict regimen, using, at the same time, repeated counter-irritation. He kept up the counter-irritant plan for a considerable length of time, for he found that, when he discontinued it, the gastric symptoms had a tendency to return. In this way he got completely rid of the dis- ease. Several years afterwards he died of an attack of erysipelas ; and, on opening his stomach, the cicatrix of an old ulcer was discovered in the vicinity of the pylorus, which was exactly the spot to which he had referred his pain during the continuance of his gastric affection. There is, perhaps, no science in which the motto, “medio tutissi- mus ibis” is of more extensive application than in medicine. Some physicians on the continent, particularly the disciples of Broussais, having repeatedly witnessed the advantages of strict regimen and local depletion in chronic gastritis, have pushed this practice too far. They seemed to forget that the system requires support and nutrition, which can be effected only through the agency of the stomach; they saw the evils which result from the use of stimu- lating food in cases of chronic gastritis; and, looking to these alone, they ran into the opposite extreme, the consequence of which was, that they kept their patients so long upon low diet that they actually produced the very symptoms which they wished to remove. The patients became dyspeptic from real debility of the stomach and the whole frame. You remember a general law of pathology to which I have alluded on a former occasion, and which I shall again mention, as it illustrates this point, namely, that opposite states of the economy may be accompanied by the same symptoms. Thus we observe, that palpitation may depend on two different causes—on a sthenic or asthenic condition—on the presence of too much or too little blood in the heart. Now, it frequently happened that patients, labouring under chronic gas- tritis, and who had been treated for a long time after the strict plan TREATMENT OP CHRONIC GASTRITIS. 53 adopted by the Broussaists, finding themselves not at all improved, went to other physicians who had different views, and were rapidly cured, by being put upon a full nutritious diet. In this way numerous cases, which water diet and depletion had only aggra- vated, were relieved, and the consequence was, that a mass of facts was brought forward and published, not long since, by a French author, against the antiphlogistic treatment of dyspepsia and chronic gastritis. It must be stated, however, that the cases which he published were chiefly those in which the depleting system had been carried to excess, and that they cannot, therefore, be received as proofs of the value of a stimulating diet in the treatment of chronic inflammation of the stomach. Bear this in mind ; the sooner you can put your patient on a nutritious diet the better will it be for him. It would be absurd to keep a patient for many months, as the Broussaists have done, on slops and gum-water. It will be necessary for you to feel your way and improve the diet gradually. Commence by giving a small quantity of mild nutri- tious food; if your patient bears it well, you can go on; if the gastric symptoms return, you can easily stop. If a small portion of the milder species of food rests quietly on the stomach, you may increase it the next day, or the day after, and thus you proceed to more solid and nutritious aliment, until the tone of your patient’s stomach regains the standard of health. Never lose sight of this fact, that you may have a case of dyspepsia depending on a chronic gastritis, in which, though you remove the inflammation by a strict antiphlogistic treatment, you may not by this remove the dyspepsia; and if you continue to leech, and blister, and starve your patient, after the inflammatory state he removed, you will do great injury. Such a patient, falling into the hands of another practitioner who treated him on a different systen, might be relieved, and his case quoted against you and your treatment, though this, at the commencement, was judicious and proper. With respect to internal remedies, the school of Broussais think that there is nothing required but cold water and gum. This is going too far. In a former lecture, I have drawn your attention to the fact, that in the treatment of acute inflammation there is a point where antiphlogistics should cease, and where tonics and stimulants are the most efficient means of cure. Of this fact, the disciples of Broussais appear to be ignorant, and they consequently declare against every remedy for chronic gastritis except leeches and cold water. Now is this right? I think not. We find that, in all cases of gastric inflammation, a change in medication seems to be useful at some period of the disease, that is, a change from antiphlogistics to tonics and stimulants, and 1 believe that in cases of chronic gastritis these remedies may be used with very great advantage, having, of course, premised depletion and counter- irritants. I believe, too, that most of the remedies, which we see every day unsuccessfully employed, would have acted beneficially, if the preparatory treatment, which I have mentioned, had been adopted. Among the best remedies of this kind is the oxide of 54 STOKES’S THEORY AND PRACTICE OF MEDICINE. bismuth; I have seen more benefit from the use of this than of any other medicine, after the treatment already alluded to. Generally speaking, the list of internal remedies for chronic gastritis is very small, but after the use of antiphlogistics, you may prescribe the vegetable tonics and oxide of bismuth with advantage. The most decidedly valuable remedy, however, in the after stage of a chronic gastritis, is the acetate of morphia, which, I am convinced, has a very powerful effect in allaying chronic irritation of the stomach. Dr. Bardsley, of Manchester, in one of his published works, entitled “Hospital Facts and Observations,” adduces many cases of gastric irritation which were completely relieved by the use of this remedy, and I am perfectly satisfied of the truth of his statements. It may be said that Dr. Bardsley’s cases were only instances of dyspepsia. But, as his cases were extremely numerous, some of them of long standing, and the symptoms very severe, the great probability is, that some of them at least must have been cases of chronic gas- tritis. I know very few books, the perusal of which I would more strongly recommend to you than Dr. Bardsley’s accurate and instructive work. The great besetting sin of medical writers is, that their statements of successful practice are grounded on a very limited number of cases, or that, in publishing the result of their practical investigations, they only give their successful cases, and leave out those in which the treatment recommended has been found inefficacious. Yet this is a circumstance which should never be neglected. If a man declares that he has discovered a cure for gastritis, or dyspepsia, and brings forward one hundred cases in which the remedy has done good, the statement is still unsatisfactory and insufficient, because there may be one thousand cases in which it has totally failed. Unless he comes forward and gives both his successful and unsuccessful cases, of what value are his statements ? Dr. Bardsley, with the candour and good sense which always characterise the philosophic enquirer, gives the result of all his cases, forms them into tables, and then leaves his readers to judge for themselves. From an inspection of these tables, you will be convinced of the efficacy of acetate of morphia in the treatment of chronic gastritis. I have been in the habit of using it with the most gratifying results after leeching, regulating the diet, and paying proper attention to the state of the bowels. There are some forms of the disease in which it is more useful than others. The particular form, in which it proves most service- able, is where there is a copious secretion of acid from the stomach (that form in which all kinds of alkalies have been exhibited), where severe pain and constant acidity are the prominent symp- toms. Here I have seen the acetate of morphia act exceedingly well. You may begin with one twelfth of a grain, made into a pill with crumb of bread, or conserve of roses, twice a day; the next day you may order it to be taken three times, and you may go on in this way until you make the patient take from half a grain to a grain and a half in the twenty-four hours. I shall here mention the circumstances of a case, which I do not mean to bring TREATMENT OF CHRONIC GASTRITIS. 55 forward as an instance of cure, but as an illustration of the extra- ordinary power which acetate of morphia possesses in relieving gastric irritation. A gentleman of strong mind and highly culti- vated intellectual powers, which he kept in constant exercise, got a severe chronic gastritis; his appetite completely declined; he had frequent vomiting of sour matter ; fetid eructations ; and such violent pain in the stomach, that he used, when the attack came on, to throw himself on the ground, and roll about in a state of indescribable agony. He applied to various practitioners, had several consultations on his case, and the opinion of the most eminent medical men was, that he had incurable cancerous disease of the stomach. These symptoms continued for several years, but for the last two or three years they were quite intolerable. He had repeated cold sweats, vomited every thing he took, even cold water, was reduced to a skeleton, and led a life of complete torture. Under such circumstances he tried, for the first time, by my advice, the acetate of morphia. He tried it first in doses of one tenth of a grain three times a day, and experienced the most unexpected relief. On the third day all his bad symptoms were gone. He had no pain, no vomiting, no sweats; his spirits were raised to the highest state of exhilaration, and he thought himself perfectly cured. He went out in the greatest joy, visited all his friends, and told them that he had at last got rid of his tormenting malady. In the evening he joined a supper party, indulged very freely, and next morning had a violent haematemesis, to which he had been for some time subject. All his old symptoms again made their appearance. He again had recourse to the acetate of morphia, and again immediately experienced relief, but the vomiting of blood again returned, so that he discontinued the remedy. This gentle- man is now in the enjoyment of good health. He regulated his diet, left off all medicine by the mouth, used warm water injections, and thus recovered from his supposed cancer. I do not bring this case forward as an instance of the curative effect of acetate of morphia, but as an instance of its powerful effect in allaying gastric irritation. I could adduce other cases in proof of its value in the treatment of the after stage of chronic gastritis, and particularly of that form in which pain and acidity are the prominent symptoms; but I perceive my time has nearly expired. At my next lecture, I shall give some other particulars connected with this subject, and then proceed to the consideration of diseases of the small intestine. 56 STOKES’S THEORY AND PRACTICE OF MEDICINE.

In speaking of the employment of counter-irritation in cases of chronic gastritis, I forgot to mention the use of friction with croton oil, which has been found beneficial in many cases of chronic inflammation. It has been extensively used by many practitioners in the treatment of chronic affections of the joints, and in various forms of pulmonary disease; and I have employed it myself in some cases of chronic gastritis with benefit. I cannot say that the cases in which I have used it presented all the symptoms of chronic gastritis, but they were certainly cases of chronic gastrodynia, with severe local pain, nausea, and loss of appetite. It is an excellent counter-irritant, and gives very little pain. The mode in which I employ it is this—take a few drops of croton oil, five or six, for instance, drop them on the epigastrium, and rub them in with a piece of lint or bladder, interposed between your finger and the skin, and the next day you have an eruption of small papulae, which you can increase at will. There is one interesting circum- stance connected with the use of croton oil frictions, which you should be made acquainted with. The liability to produce counter- irritation, seems to depend upon the absorption or non-absorption of the croton oil; if it be absorbed it will purge, but if it be not it will produce counter-irritation. In cases of this kind, therefore, where it produces the necessary degree of irritation in the skin, the chances are, that it will not act disagreeably by bringing on ca- tharsis. I have only seen one case where there were both the eruption and catharsis. This was a gentleman who had lately suffered from dysentery in warm climates.1 I may also mention, that, in convalescence from an attack of chronic gastritis, you must pay great attention to diet for a long time, because there is no affection of any organ in the body, in which an error in diet so rapidly induces a return of the original symptoms, as in diseases of the stomach, while each return of the disease renders the attack more dangerous and unmanageable, until at last disorganisation takes place. This leads me to speak of organic disease of the stomach. On 1 There is one variety of revulsion which is effectual in removing chronic gastritis, and, indeed, every form of dyspepsia, at times when every other remedy has failed. We allude to constant change of air, society, and scene- ry, with exercise in the open air, such as traveling affords. Even a single voyage, as from one side of the Atlantic to the other, is often sufficient to break in upon the morbid catenation; and Dr. James Johnson remarks, em- phatically, that he believes every form of dyspepsia, unaccompanied by organic mischief, would yield to the revulsion produced by traveling two or three thousand miles over such a country as Switzerland.—R. D. 57 ORGANIC DISEASE OF THE STOMACH. this subject I shall be very brief; the best mode of communicating information will be to exhibit these preparations ; you will derive more instruction from their inspection than from any lecture I could deliver. (Dr. Stokes here exhibited a number of beautiful preparations from the Park street museum, illustrative of various organic lesions of the stomach.) Here is a case, which some pa- thologists would call cancer, others chronic gastritis. I may remark here, that pathologists are divided as to what is the cause of cancer of the stomach, but the best informed are of opinion that, in those cases of gastric disorganisation which are called cancer or scirrhus, all that can be demonstrated by the knife is referable to the results of chronic inflammation. This is a different propo- sition from saying that chronic inflammation alone will produce cancer. As yet we know little of cancer; dissection of cancerous organs gives but scanty information ; but this seems certain, that, in particular conditions of the economy, an inflammation of the stomach will end in cancerous disease. Here is an excellent pre- paration of the stomach of a person who died of cancer of that organ. For several years before his death he had a jaundiced look, an emaciated appearance, frequent vomiting, and severe pain towards the termination of the digestive process, a circumstance which denotes disease of the pylorus. He also had hsematemesis. You see the inner surface in the vicinity of the pylorus presents ulcerations of the mucous membrane and thickening of the sub- mucous cellular tissue. The pylorus itself does not appear to be at all contracted, but the parts around it are in a state of extraordi- nary disease. Look at the preparation again, and say what could bitters, or acids, or alkalies, or tonics, have effected in a case of such extensive disease. Here is a stomach in a state of long con- tinued chronic inflammation, and exhibiting lesions, which some would designate as cancer of that organ. Now, though I do not know the treatment which this patient underwent, I would venture to say that he took plenty of the usual anti-dyspeptic medicines. Yet, in a vast number of cases, where enormous quantities of these remedies are taken daily, the stomach is in as bad a state as that preparation exhibits, and I feel the more strongly convinced of this, because I am aware that many persons die. after having gone through the whole routine of anti-dyspeptic practice, and, when they are opened after death, incurable disease of the stomach is discovered. Here is an example of vast cancerous disease of the stomach ; here is a very interesting specimen of chronic gastritis, chiefly representing a most remarkable and circumscribed ulcer at the termination of the stomach. Here you see is the ulcer, with raised, thickened, and introverted edges. Now, in all probability, this ulceration was exceedingly chronic, for you perceive nature has been at work with it, and has made some attempts at repara- tion. It is in such a case as this that patients generally refer their pain to a particular part of the stomach : digestion goes on without any pain until the food reaches a certain point, when acute pain is felt, and this continues until it is relieved by vomiting. The 58 STOKES’S THEORY AND PRACTICE OF MEDICINE. occurrence of this symptom, after an attack of acute gastritis, would lead you to suspect the formation of one or more ulcers, and the persistence of this localised pain should induce you to persevere in employing every means in your power calculated to remove the disease. The preparation which 1 now exhibit is interesting, as it shows the effect of corrosive poison on the stomach. The patient, to whom this stomach belonged, died in consequence of swallowing a quantity of sulphuric acid; here you see the consequences—the mucous membrane is black and disorganised, exhibiting this rag- ged appearance. In some cases of malignant fever we have found the stomach presenting somewhat similar appearances; and the same state of the stomach is described by some writers as occur- ring in cases of intertropical fever. Here is a preparation which you should inspect; chronic gastritis with a large ulcerated patch in the centre of the stomach. Here is another example of extensive cancerous disease. A very few words will suffice for the state of the science on the subject of cancer of the stomach. It is very hard, nay, even almost impossible, to draw a line of distinction between the symptoms of cancer of the stomach and chronic gastritis, and I believe it is ad- mitted on all hands that the same causes give rise to both. Long continued irritation will, in one case, produce cancer of the sto- mach, in another, chronic gastritis. Again, it is admitted by many, that what is called cancerous ulceration of the stomach has no appreciable difference from ulceration in various other organs ; and hence some other persons have gone so far as to say that there is no such thing as cancer of the stomach (separately considered); and that all the cases adduced of it are nothing more than so many forms of chronic gastritis. In the present state of medicine, we are not, indeed, possessed of any data which would enable us to come to a final determination on this question. It is certainly impossible to determine this point; but if there be any thing pecu- liar in cancerous matter, similar to tubercular or melanotic matter, there is no reason why, under the influence of inflammation, it should not be developed in the stomach as well as in any other part of the body. But whatever views we eutertain on this subject, we must confess that, in the majority of cases, there is a chronic gastritis, and that the principles of treatment which would alleviate the patient’s sufferings and prolong life, are those which are calcu- lated to prevent the occurrence of gastric inflammation. The more you approximate the treatment of cancer to that of chronic gastritis, the greater comfort will you afford your patient, and the more will you prolong his existence. The most celebrated case on record of this affection is that of the Emperor Napoleon. He died with extensive ulceration of the sto- mach, which, of course, was called “cancerous,” and there were also distinct traces of disease in the liver, the mucous coat of the intestines, and the lungs. His disease was believed by himself to have originated in the stomach, and to this opinion he adhered, notwithstanding the results of some solemn consultations, at one of $9 ORGANIC DISEASE OF THE STOMACH. which his affection was declared to be an “ obstruction of the liverf with a “ scorbutic dyscrasy” At another it was pronounced to be a “ chronic hepatitis” and a course of mercury recommended! When we reflect on this, and read in the account by Gaubert,- (which you will see in the Examen des Doctrines Medicales,) the regimen which was used, and the list of stimulating medicaments employed, you will not wonder at the words of this great man, when he was pressed to take more drugs, to swallow the universal nostrum, mercury, to which he had the greatest aversion. “ Your disgusting preparations are good for nothing. Medicine is a collection of blind prescriptions, which destroy the poor, sometimes succeed with the rich, but whose whole results are more injurious than useful to humanity.” But he got mercury, notwithstanding, mercury for his “digestive organs;” to “excite the liver;” to “re- move its obstruction,” and mercury to create bile, and purgatives to remove it; and tonics, and antacids, and stimulants; and he died in torture, and his body was opened, and the stomach was found “ cancerous"' I should not omit mentioning to you, that in those cases of chronic gastritis which run on to an incurable stage, the best treatment consists in a careful regulation of diet, in keeping the bowels open by enemata, or the very mildest laxatives, and in avoiding every thing capable of producing excitement. You will also derive advantage from the employment of gentle counter- irritation. and from the internal use of narcotics, which in such cases appear to have a more beneficial effect than any other class of remedies. With the exception of these, I do not know any other kind of medicine you can safely employ ? and I believe that, in the majority of cases, you will find that the patients have taken already too much medicine. Anxious for relief, and urged on by the hope of obtaining some remedy capable of relieving their suf- ferings, they have recourse to every grade of quacks, are persuaded to swallow every kind of drug, and are subjected to every form of harassing and mischievous treatment. The diet which you pre- scribe for such patients should be sparing but nutritive; give the stomach as little to do as will be consistent with the support of life and strength ; and you may take it as a general rule in the treat- ment of all chronic affections of the digestive tube, whether cancer of the stomach, scirrhus of the pylorus, or stricture of the intestines, that there are two great principles of general application—preserv- ing a gently open state of the bowels, and allaying inflammatory excitement. Let us now proceed to the remaining parts of the digestive tube, of which the next in order is the duodenum. I shall not dwell much to day on the subject of duodenitis ; as I shall revert to its consideration when speaking of jaundice, because inflammation of the duodenum is a common cause of jaundice, perhaps the most common, if we take the whole of its cases to- gether. You are not to suppose that I wish to inculcate the doctrine that jaundice is a necessary complication in duodenitis: 60 STOKES’S THEORY AND PRACTICE OF MEDICINE. but it has been proved that there is an extraordinarily frequent coincidence between both, and that jaundice very often seems independent of any mechanical cause, such as an obstruction of the biliary ducts. So far from this, that, in some cases, particularly those which are produced by, or accompany, a duodenitis, we have intense universal jaundice at the same time that the bile is flowing freely into the digestive tube. The researches of the immortal Bichat gave the first hint which directed the attention of practitioners to the circumstance, that, in many cases where jaundice had existed during life, there was no obstruction or disease in the liver or biliary ducts, but that in such cases there was always more or less inflammation in that part of the digestive tube into which the bile was immediately discharged, and this led ultimately to the discovery of the connection which exists between inflammation of the duodenum and jaundice. In treating of the sympathies which depend upon continuity of sur- face, Bichat refers to the connection which exists between the surfaces of mucous membranes and the ducts which open on them, and endeavours to show that the natural mode of excitement in all secreting glands is a stimulus applied to the surface on which their ducts open. As examples of this, he instances the effect which food and other substances, applied to the mucous membrane of the mouth, have in stimulating the salivary glands ; the effect which stimulants, applied to the conjunctiva, or nose, have on the lachrymal gland, and many others. Hence Broussais concludes that, when the mucous surface of the duodenum is thrown into a state of excitement, we may have a consequent affection of the liver, for the duodenum bears the same relation to the liver as the mouth does to the parotid glands. That this is frequently the case, I think, is very probable. It is now established, that the cause of the yellowness in what has been called yellow fever, is disease of the upper part of the digestive tube, in which the duodenum is always involved ; and that the fever itself (the typhus icterodes of the nosologists) has been found to be greatly connected with in- flammation of the stomach and duodenum. During the epidemic of 1827, we had in the Meath Hospital a great many cases which bore a striking resemblance to the yellow fever of warm countries, and particularly in this, that they were accompanied by intense jaundice, and inflammation of the upper part of the digestive tube. You will see in the works of Rush and Lawrence, two of the best American writers on yellow fever, that, of the numerous bodies they examined, there were scarcely any in which the jaundice was found in connection with liver disease, but that in all cases there was intense inflammation of the digestive surface. I shall return to this subject when I come to speak of liver disease. With respect to the jejunum, I may state that we know very little of the symptoms which characterise inflammation of this part of the intestinal canal; and it is a curious pathological fact, that this portion of the tube is, of all others, the least liable to inflammation. In point of fact, we have no means of ascertaining what are the ORGANIC DISEASE OF THE STOMACH. 61 prominent symptoms of inflammation of the jejunum, because, in almost every case in which jejunitis has been discovered, there has been also extensive disease of the rest of the small intestine. We have cases of simple gastritis ; there have been also cases of distinct disease of the duodenum. We may have disease in the lower third of the ileum, unaccompanied by an affection of any other part of the tube. The same thing may occur in the case of the caecum, colon, or rectum, but it seldom or never occurs so far as the jejunum is concerned. I shall therefore pass over jejunitis, and proceed to draw your attention to one of the most important diseases to which the human subject is liable—inflammation of the ileum. Inflammation of the ileum is a most important affection, for two reasons ; first, in consequence of its extraordinary frequency, and, in the next place, of its insidious latency, the disease generally requiring a considerable degree of tact and experience on the part of the practitioner to make out its diagnosis with certainty. In fever, it is the most frequent of all forms of intestinal inflammation; and hence Broussais, finding inflammation of the ileum of such constant occurrence in fever, concluded that fever was only symp- tomatic of intestinal inflammation. Further researches have shown that he was mistaken, and that the inflammation of the digestive tube is, in many cases, secondary ; but it is still a circumstance of almost constant occurrence, and in many cases of fever is the cause of death. Now, the portions of the intestinal tube most commonly affected in fever are the stomach and lower part of the ileum ; and the frequent occurrence of this in fever is very remarkable. There are few cases of typhus without it. In some cases of typhus you will, on examination after death, be astonished to find exten- sive disease of the intestinal canal, which, during life, had not attracted any particular notice, and this you will most commonly find in the lower part of the ileum. So common is it, that Louis says that ileitis is the grand anatomical feature of typhus fever ; that is, had he been obliged to pitch on the lesion of same parti- cular organ as giving a character to typhus, he would say that it was ileitis. There are other diseases, too, in which inflammation of the ileum forms the principal complication. In the diseases of children, which go by the names of worm fever, remittent fever, and bilious fever, I believe that ileitis is generally the first affec- tion, and that the fevers are only symptomatic of it. It constantly occurs at some period or other of tabes mesenterica ; and I believe that in many cases it precedes the affection of the mesenteric glands. It is exceedingly common in phthisis. In every case of phthisis, where diarrhoea has lasted for some time, the probability is, that there is ulceration in the caecum, colon, and lower part of the ileum. Now, what is the nature of this ileitis ? This preparation, (hand- ing one for inspection,) which I beg of you to hand round, will furnish a very good illustration of the disease. Here is a portion of the intestine exhibiting various distinct ulcerations of different 62 STOKES’S THEORY ANIi PRACTICE OF MEDICINE. sizes, occupying the situation of the mucous glands. I do not mean to say that the character of the disease consists in this dis- tinct ulceration; it is an essential disease of the mucous membrane, and of its glands, which exist in great numbers on the surface of the lower third of the ileum, and are called solitary and aggregate. These glands frequently take on the inflammatory condition, become softened, run into ulceration, and produce extraordinary- sympathetic irritation of the whole system. There has been lately a great deal of discussion with respect to the question—Whether disease begins in the glands or in the mucous membrane, and whether we can separate disease of the glands from disease of the mucous membrane. This has been carried to a great extent; and a change has been attempted to be made in the name of the disease, it being entitled dothinenteritis by those who say that the inflam- mation commences in the glands. But this I think is a mere refinement, and is carrying the thing too far. It is next to impos- sible for the glands to be affected without involving the mucous membrane, or for the mucous membrane to be affected without an extension of the disease to the glands. We sometimes, however, see the mucous membrane diseased without the glands being ap- parently engaged; but I think the glands are never engaged without the co-existence of disease in the mucous membrane. In this pre- paration you see the mucous membrane is just giving way; and here is an actual slough, where the mucous and submucous tunics have yielded to the inflammation. In the lower portion of the ileum we meet with an infinite variety in the size and number of the ulcerations: in some they are very close and numerous, in others there are only two or three detached ones ; in some, the whole circle of the intestine is destroyed ; and the ulcer is nearly as broad as the palm of your hand. It is interesting to consider, with respect to the pathology of the respiratory and digestive sys- tems, how it comes that ulceration of the mucous membrane is so much more common in the digestive apparatus than in the respi- ratory. For one ulceration of the bronchial mucous membrane from acute disease, you will have one hundred of the gastro- intestinal. For this peculiarity we cannot clearly account; but there seems to be more development in the digestive than in the respiratory system, and that this over-development produces a tendency to disease. This, perhaps, is an approximation to an explanation of the facts; and to this may be added, that the mucous membrane of the intestines is exposed to the influence of a much greater variety of agents. It is difficult to give an accurate idea of the symptoms of ileitis, as we can only arrive at a knowledge of it by negative evidence, or, as the French term it, u par voie d'exclusion.” In a case of gastritis and of inflammation in the upper part of the digestive tube, the most prominent symptoms are thirst and vomiting. In this affection, too, there is thirst, but it is by no means so urgent as in the former cases, and there is generally no vomiting. In a case of acute gastritis there is always a desire for ORGANIC DISEASE OF THE STOMACH. 63 cold drinks. In this disease there is also a desire for fluids, but the patient prefers them warm. Here you perceive two symptoms connected with the predominance of disease in the upper part of the digestive tube are absent—vomiting and the desire for cold drinks. Now, you are aware that, in a case of inflammation of the colon and rectum, the most prominent symptoms are diarrhoea, tenesmus, and the passing of a quantity of morbid secretions. These symptoms, in a case of ileitis, are either wanting, or they are so slight as to excite very little notice. If, then, in a case of intestinal disease, we abstract the characteristic symptoms of disease in the upper and lower part of the digestive tube from the pheno- mena of the existing disease ; if we find that it presents symptoms which do not properly belong to either the stomach, duodenum, colon, or rectum; we conclude that it must depend on a lesion of the remaining part of the canal, and we are in this way led to the diagnosis of ileitis. Let us enumerate the symptoms of an ileitis. In the first place, thirst, without a preference for cold drinks; in the next, absence of vomiting; again, in the early period of the disease there is generally a tympanitic state of the belly, and the patient seldom complains of pain, even in fatal cases. This is a point of extreme importance. There is, however, most commonly a degree of tenderness over the ileum, which you will be able to detect by an accurate examination, and this tenderness presents a remarkable difference from the tenderness of gastritis, both in de- gree and situation. It is very seldom so exquisite as in a case of gastritis, the patient can bear a considerable degree of pressure, and the tenderness, in place of being towards the epigastrium, is situated between the umbilicus and the crest of the ileum on the right side ; here pressure excites pain. The tongue in this affec- tion is generally of a dirty white, pointed, and red along the edges and tip; the pulse is quick and small, and the face is contracted. As to the nature of the discharges from the bowels they are ex- ceedingly various ; there has been as yet no diagnosis founded on their appearance, and in some fatal cases they have been observed to retain an almost perfectly healthy appearance throughout. What would the gentlemen who draw their diagnosis from the chamber-pots say in such cases ? I have seen perfectly natural stools in cases which immediately after have terminated fatally, and where, on examination after death, there was a vast extent of ulceration in the ileum. In addition to the symptoms just recited, the patient most commonly has fever, and this presents itself under various forms, frequently assuming the type of a simple continued fever ; hence, in a great many cases, the patient is merely sup- posed to labour under simple continued fever, and the existence of extensive inflammation of the ileum, is entirely overlooked. In other instances, there is more or less prostration, which increases with the progress of the disease, and the fever frequently receives the appellation of typhoid. Under these circumstances, the patient often gets bark and wine, every means is taken to support his 64 STOKES’S THEORY AND PRACTICE OF MEDICINE. strength and remove the typhoid condition of the system, the inflammation of the intestine is exasperated by neglect and mal- treatment, the patient dies, and, on dissection, the ileum presents an enormous sheet of ulcerations. In cases of this kind, where the diagnosis depends as much on negative as on positive circumstances, it is of importance to have a direct sign by which we may be able to ascertain, with some degree of certainty, the existence of a suspected enteric inflamma- tion, and I think I have discovered one, which I believe has not been as yet noticed ; this is increased pulsation of the abdominal vessels. In many cases of acute inflammation of the brain, the increased pulsation of the carotids has been frequently remarked, and every one sees, that, under such circumstances, there is an undue excitement of these vessels, or, in other words, that there is a want of proportion between the action of the carotids and that of the arteries of the extremities. If your finger be attacked by paronychia the same phenomenon is observed, the artery leading to the inflamed finger beats much stronger than the artery of the corresponding one on the opposite side. From these circumstances I was led to conclude, that, in cases of acute inflammation of the digestive tube, there would be increased pulsation of the abdominal aorta; and on following up the investigation by examining several persons who had distinct and well marked intestinal inflammation, I found that my conclusions were well grounded. In such cases, I found not only a remarkable throbbing of the abdominal aorta, but I also discovered that this throbbing was prolonged to the fe- moral arteries, and that, on the other hand, there was little or no corresponding excitement in the arteries of the upper extremities. LECTURE VIII. Diseases of the small intestines—Symptoms of ileitis—Occurrence of diarrhoea with fever symptomatic of this form of inflammation—Frequency and symptoms of the disease in children—Tubes mesenterica, treatment of. At ray last lecture I was engaged in the consideration of disease of the small intestines : let us now resume the subject. You re- member I mentioned to you that most of our knowledge of the inflammatory affections of the small intestines refers to the ileum, and that, in point of fact, we know little or nothing of disease of the jejunum. This, however, is not of much importance, as, of all the parts of the digestive tube, the jejunum is the least liable to disease, and is seldom or never engaged without the co-existence of disease in the ileum or duodenum. You recollect I drew your attention strongly to the extreme frequency of inflammation in the lower third of the ileum, and the importance which it derives from DISEASES OF THE SMALL INTESTINES. this as well as from its insidious latency. I showed that it was one of the most common secondary lesions in typhus fever, and a frequent cause of death. This cannot be impressed too much upon your minds—it is a point of pathology on which the best informed medical men are agreed. It may also, and very often does, occur as a pure idiopathic affection, without being preceded or superin- duced by that morbid state of the whole economy to which we give the name of fever. I said it was extremely common in chil- dren ; that here it was in many instances mistaken for worms, or bilious, or remittent fever ; that it constantly occurred during the progress of tabes mesenterica, and often appeared to have the initiative. I alluded to the discussion which has arisen as to the question whether disease begins in the glands or mucous mem- brane, and stated that such discussions are useless, as it is impos- sible to separate the two affections in diagnosis or treatment, and practical medicine gains nothing by the distinction. With respect to the symptoms of ileitis, I observd that they were those of a general affection of the digestive tube, the phenomena which indicate irritation at its upper and lower part being absent. That if you abstract from symptoms of a general affection of the intestinal canal, the vomiting and desire for cold drinks which characterise inflammation of the upper part, and the diarrhoea and tenesmus which denote disease of the lower part, you will have the diagnostic marks of an ileitis. At our last meeting I showed you some preparations illustrative of this disease; I intended to have exhibited others of the same kind to-day, but regret that I cannot lay my hands on them at present. Allow me to rehearse the symptoms of ileitis once more. Thirst, without desire for cold drinks ; absence of vomiting, and of the characteristic symptoms of inflammation of the colon and rectum; early tympanitis, gene- rally on the second day of the disease ; absence of pain, but exist- ence of tenderness on pressure between the umbilicus and the crest of the ileum ; pointed tongue, of a dirty white on the upper surface, and red at the sides and tip; contracted features; quick, small pulse; fever, and, what I forgot to mention in my last lecture, scanty high-coloured urine, a very constant symptom, so much so that I have known this disease mistaken for an affection of the kidney, and the patient treated accordingly. I must add, that the patient died, that the kidney was found perfectly healthy, the ileum in a state of violent inflammation, and the suppression of urine to be referred to this cause alone. I drew your attention at my last lecture to the increased pulsa- tion of the abdominal aorta and its immediate branches, and stated that I looked upon this as a direct sign of abdominal inflammation. I do not mean to say that every case of increased action of the great abdominal arteries is significant of ileitis or intestinal inflam- mation. We see unusual pulsation of the abdominal aorta in hysterical females, and see it subside under the use of antispas- modics ; we see it in painter’s colic; we see it in cases of extreme emaciation ; we see it in disease of the aorta, or of some of its first 66 STOKES’S THEORY AND PRACTICE OF MEDICINE. large branches. What I wish to draw your attention to is this: where we have this symptom in addition to other signs of inflam- mation of the digestive tube, it is of considerable value as a diag- nostic. You may remember I stated that ileitis, from being generally attended by fever of the continued type, has been frequently supposed to be simple continued fever, and that this was one of the conse- quences which resulted from the latency of the disease. Petit was the first who described this disease rightly. He described it under the name of entero-mesenteric fever, that is to say, fever depending on disease of the mesenteric glands and small intestine. The fol- lowing is an outline of his description : “ The attack comes on with debility, irregular fever, quick, small pulse, sunken countenance, perhaps some diarrhoea, a lustrous expression of the eye.” I may remark here that the occurrence of diarrhoea without any evi- dent affection of the great intestine, and accompanied by fever, is almost always a sign of ileitis. It too often happens that practi- tioners, as I before remarked, prescribe for names. In cases of pulmonary disease, if the patient has fever, with copious expecto- ration, they say he is labouring under an attack of bronchitis ; but in case of intestinal inflammation, accompanied by increased se- cretion, it is different; they merely say he has diarrhoea, and prescribe for it without connecting it with its proper cause. The general rule is, that when you have diarrhoea with fever, there is inflammation of the digestive tube. In inflammation of the ileum the patient generally lies on his back, and avoids motion as much as he possibly can, his skin is dry and harsh; he is feverish; he has thirst, but little desire for cold drinks; he scarcely ever vomits ; his alvine dejections are sometimes thin and purgative, sometimes figured and natural. But there is one circumstance which is of considerable importance in pointing out the amount of disease, even in cases where patients have considerable diarrhoea, and this is, that the diarrhoea is not sufficient to account for the extraordinary prostration. There must be some cause for the great reduction of vital power besides the mere diarrhoea, and I must state to you that there are few diseases which bring on such rapid prostration as inflammation of this por- tion of the digestive tube. In the advanced stage of this disease the patients have cold skin, subsultus tendinum, petechiae, involun- tary discharge of urine and faeces, low delirium, coma, gangrenous ulcerations of the back, sinking of the powers of life, effusions into the head and chest, in fact, all the symptoms which characterise the last stage of typhus. Generally speaking, the disease is more or less prolonged, and the patients die of exhaustion, but in some cases the approach of death is more sudden and formidable. Some of the ulcers pass deeply into the substance of the intestine, perfo- rate all its coats in succession, the contents of the intestine escape into the peritoneum, and the patient is carried off by a rapid peritonitis. Inflammation of the ileum is very frequently met with in chil- DISEASES OF THE SMALL INTESTINES. 67 dren, and it is most important that you should be aware of the extreme frequency, as well as the symptoms, of this disease, in those little creatures. There is one fact in pathology which seems not to be generally acted on—that there is a class of diseases which are intra-uterine, and with which a child may be born. There are a great many cases of this kind on record, hut still, I must confess, there is a great scope for investigation, and that our know- ledge on this subject is imperfect. I believe that any one who has the opportunity of dissecting a great number of still-born children, or of those who die immediately after birth, would, by examining the state of the different cavities, and publishing the results of his examinations, earn for himself very great reputation. It is a well known fact that children may be born with hydrocephalus, with tubercles in the lungs, with acute inflammation of the stomach ; nay, more, children have been known to be born with chronic gastritis, and with old ulcerations in the ileum and colon. When children happen to be born with gastro-enteric disease, they are puny and weak; the fact of this occurrence is generally overlooked, the case is considered to be one of general debility, and hence most of those children are lost in consequence of their medical attendants being ignorant of the real nature of the disease. It is a very curious fact, too, that where enteric disease occurs in very young children, it is frequently met with without any accompanying fever, and this is a point of great importance. Here is a fact not gene- rally known. A new-born infant has vomiting, swelled belly, con- tracted features, but at the same time he has cold skin and feeble pulse ; he has no distinct symptoms of fever, and a puny and feeble state of constitution appears to be the prominent symptom. He dies, and on opening the body you find distinct traces of enteric inflammation. The younger the child is, the less will be the chance of fever occurring as a sign of enteric inflammation. It seldom happens that this takes place after dentition, but before it is very common. Now, what are the circumstances which would enable us to re- cognise this disease in children who have passed the period of first dentition ? If you find the child vomiting, thirsty, with swelled belly, hot skin, a tendency to diarrhoea, and an erythematous red- ness about the anus, you may be sure that there is disease of the digestive system ; if the child is restless, and you perceive that the symptoms of irritation of the head are coming on, you will be more certain, and in such cases pathology will inform you that the dis- ease is chiefly in the ileum. In the advanced stage the diarrhoea is lessened, but the belly continues tympanitic, the child exhibits traces of long suffering, and the circumstance of the teeth not being developed gives it the appearance of premature old age, which cannot be mistaken by an experienced eye, and is a sign of long continued and extensive intestinal disease. In some cases, the child gets a common attack of diarrhoea ; this is neglected, but after going on for two or three days, symptoms of fever begin to appear. Here we arrive at a practical rule. Where a child has 68 STOKES’S THEORY AND PRACTICE OP MEDICINE. diarrhoea, and, after labouring under this for a few days, gets an attack of fever, you may be almost sure that it is a case of enteritis, and that you will be acting wisely in treating it as such. In the opinion of many well-informed practitioners, that form of fever which has been called infantile remittent, is only an example of this disease. In proof of this fact, Dr. Marsh, my friend and pre- decessor in this school, in his paper on jaundice, makes some excel- lent remarks on this subject. “ There is yet one form of disease of very frequent occurrence, the seat of which is in the stomach and small intestines. That to which I allude, is the infantile remittent fever, or, as it is vulgarly termed, the worm fever of children. Its characteristic symptoms, if closely analysed, will be found all of them to point to the mucous surface as the original seat of morbid action.”—Dublin Hospital Reports, vol. iii. It would be well for medicine, if the valuable information con- veyed in Dr. Marsh’s paper was more universally diffused. I feel convinced that many children fall victims to malpractice under circumstances of this kind. A child gets symptoms of diarrhoea, has irregular or bad appetite, and swelled belly. The disease is called worm fever ; he gets a dose of calomel and jalap, and, per- haps, passes some worms; for, when we come to speak of worms, we shall find that disease of the mucous surfaces is intimately connected with worms, and, in the opinion of one practitioner, worms may be the result of enteric inflammation. Well, some worms are passed; the purgative is again used ; the child may not pass any more, or he may pass one or two in a week to en- courage the practice. But all the symptoms of intestinal inflam- mation, the diarrhoea, the tympanitis, the thirst, the fever, are supposed to depend upon the presence of more worms, and these are to be evacuated by purgative medicine; and thus the affair goes on, until the child falls into tabes mesenterica, or gets sympa- thetic inflammation of the brain, and dies of hydrocephalus. I regret to add, that in many cases of this kind the head alone is opened; a little fluid is discovered in the ventricles of the brain, the doctor’s diagnosis of the head is found to be correct, and all parties are satisfied. In cases of this kind, the early application of leeches to the belly, the regulation of diet, keeping the bowels gently open by enemata and mild counter-irritation, would have saved the patient. This is not mere theory; it is but a statement of facts, supported by the experience of practical men. I wish to say a few words here with respect to tabes mesenterica. In a course of lectures like the present, it would be impossible to examine, in detail, the different forms of this disease; it will be as much as I can do to draw your attention to the general principles of its pathology and treatment. The term, tabes mesenterica, is employed to designate that species of consumption which depends upon disease of the mesenteric glands. The common idea formerly entertained with respect to this affection, and, I believe, still to a great extent, is, that the disease first commences in the mucous glands, and from these extends to the lymphatic ganglia of the DISEASES OF THE SMALL INTESTINES. 69 mesentery, which, in their turn, become enlarged, thickened, and less pervious, so that a sufficient share of nutriment cannot be absorbed, the consequence of which is, that the patient dies of atrophy and exhaustion. With such views of the case, the prin- ciples of treatment consisted in employing a class of medicines called deobstruent, the operation of which was supposed to be efficacious in removing this obstruction, this deposition in the sub- stance of the mesenteric glands, and the enlargement by which it was accompanied. This was, and this, I am sorry to say, is the idea still entertained by many. What is the actual state of the science with respect to this disease ? It is found that the glands are certainly changed in their structure, and that they are mani- festly enlarged; but this is only a link in the chain of phenomena, for it has been proved that in the majority of cases the disease is ushered in by enteritis, and that the swelling of the glands is the result of disease, propagated along the course of the lymphatics from the mucous surface of the intestines to the mesenteric ganglia. This preparation, which I shall send round, will give you an idea of the actual state of the disease. Here is one of the glands which has been cut through; it exhibits the cheesy texture commonly observed in this disease, but you can perceive there are a number of lines running towards each of the glands ; these are the engorged lymphatics, which, you see. correspond with ulcers on the mucous surface of the small intestine. That this is the true pathology of the disease will appear from the following cir- cumstances :—First, it has been proved that the glands of the mesentery commonly become inflamed, enlarge, and suppurate, in cases of inflammation of the mucous membrane of the intestinal canal in the adult. A patient gets enteric inflammation and dies ; on dissection, we find distinct marks of disease in the intestines, and, in addition to this, we find the glands evidently diseased. Here is one fact. In the next place, it has been proved that, in a great many cases of tabes mesenterica, if you retrace the history of the disease, if you go back to its first and earliest phenomena, you will find that it began with the symptoms of what has been termed remitttent fever, or that the patient had enteritis or diarrhoea, which afterwards became chronic, and that then the symptoms of tabes mesenterica began to appear. In the third place, you will find that, in a vast number of cases, where a fatal termination has oc- curred, if you pursue your dissection, and slit up the whole of the ileum, you will discover numerous old ulcerations of the mucous membrane, and find that the lymphatics which correspond with these ulcerations are in a state of manifest disease. Lastly, it has been observed that the best treatment for tabes mesenterica is that which is calculated to remove enteric inflammation, and that the old treat- ment, founded on the principle of removing obstruction, by the use of alkalies, absorbents, and solvents, is erroneous and false in the majority of cases. So that we have proof of the origin of this disease in intestinal inflammation, drawn from the occurrence of analogous affections in the adult, from the phenomena of the disease 70 STOKES’S THEORY AND PRACTICE OF MEDICINE. in its early stage, from morbid anatomy, and from treatment. I think there can be no doubt that, in most instances, it commences by intestinal inflammation. Of course a predisposition to disease of the glandular system will favour the occurrence. But is there no case in which the disease has commenced in the glands, and where the mucous membrane of the digestive tube is secondarily engaged 7 My answer to this question is, in a few cases we can- not prove that the disease commenced in the mucous membrane, and there is no reason why the glands of the mesenterica should not be liable to primary tuberculous or scrofulous deposition as well as those of any other part of the body ; but, in a vast number of instances, the enlargement of the mesenteric glands is secondary, and resembles the inflammation of the inguinal glands which re- sults from chancre on the penis. I would advise you to consult the Commentaries on Pathological Propositions by Broussais. On this subject, also, Dr. Mackintosh’s Practice of Physic. There is one thing more connected with this disease, which is of considerable importance, and to which I shall briefly draw your attention, and this is, that this inflammation of the glands of Peyer and Brunner, this dothinenteritis, as it has been called, is a very common cause of slow convalescence in fever. You will meet with cases of fever, which will go on to the 17th or 21st day, and then something like a crisis takes place; you expect that from this time forward the patient will get progressively better; but in the course of a few days you will be surprised to find no amendment, and that he is not gaining strength ; you feel his pulse, and find it quick and small, his attendant informs you that he is restless at night, and when you ask him how he feels, he says he has no particular complaint, but that he is very weak, gets no sleep at night, and has no appetite. Under these circumstances you are anxious to find out what his disease is; you enquire into the state of the heart, lungs, and brain ; you find no evidence of disease in any of these organs; you run over in your mind the symptoms present, the feverishness, quick pulse, want of appetite, restless- ness, and finding some degree of abdominal tenderness and tym- panitic swelling, you arrive at the conclusion that the return of health and strength is impeded and delayed by the existence of a dothinenteritis. The first person who discovered this fact was Dr. Cheyne. “ In these cases,” says he, “ the distress of the patient often bore no proportion to the danger he was in; the former was very little, while the latter was extreme. The disease would pro- ceed without violent symptoms; nay, a patient would seem to be recovering, although without any critical discharge ; he would call for full or middle diet, and for days take his food regularly. The only circumstance in his situation which demanded attention was, that he regained neither flesh nor strength, and he expressed no desire to leave his bed. Then, his pulse again became quick and his tongue dry ; and he would complain of dull pain and un- easinesss in his belly, attended with soreness on pressure, and a degree of fulness in the upper part of the abdomen. Then came DISEASES OF THE SMALL INTESTINES. 71 on a loose state of the bowels, and great weakness. Probably at the next visit the patient was lying on his back, with a pale sunken countenance, and a very quick pulse; his mind without energy. Then his stools (mucous) passed from him in bed, and the urine also. Perhaps a hiccup came on ; next his breathing became fre- quent, in which case death was at no great distance.” In all these cases the mucous membrane and glands were found in a state of decided disease. Now, what was the nature of this disease ? It came on as a secondary affection during the course of fever, became more marked and intense, and finally destroyed the patient. I have seen very many cases of this disease. I give you this as a general rule:— when, after the apparent termination of a fever, your patient con- valesces very slowly and imperfectly ; when you find that he is becoming weak, that his pulse is quick, his belly tympanitic, his thirst still present, and all this without evidence of disease in the respiratory, circulating, or nervous system, you may suspect inflammation of the mucous glands of the digestive tube, which may terminate in deep ulcerations; and you will not be surprised if your patient should be carried off by rapid peritonitis, occasioned by an ulceration of all the coats of the intestine. I have witnessed many instances of the truth of this statement. It has been objected to the doctrine, that infantile remittent fever and tabes mesenterica depend on inflammation of the mucous membrane of the digestive tube, because it has been found that purgatives are sometimes useful in the treatment of the disease; and those who bring forward this objection ask, “ if purgatives give relief, how can it be intestinal inflammation ?” Now, what are the real facts of the case ? These cases, which have been relieved by purgatives, are cases in which purgative medicine has been given in the early stage, and has been productive of benefit; or, in other words, where the disease is only just commencing, and where its cause is proved to be the presence of irritating matter in the bowels. A physician is called to a case of this kind ; he gives a purgative ; a quantity of offending matter is evacuated, and the child gets better. You should act in the very same way, and have recourse to purgatives whenever you have reason to suspect the existence of irritating or indigestible matter in the bowels. You are to employ purgatives on the same principle as every one em- ploys emetics in cases where corrosive poison has been swallowed; but no one is inclined to think that he will be able to cure the dis- ease by the continued use of emetics. But, unfortunately, persons do not attend to the actual state of the digestive tube ; they go on prescribing purgative after purgative, until the irritation, which was originally produced only by indigestible matter, becomes exa- cerbated, and terminates in ulceration of the intestinal mucous surface, accompanied by all the symptoms of tabes mesenterica. The treatment of this affection is both simple and easy, particu- larly when the patient applies to you at an early period. In the case of children, one of the first things you have to determine is, 72 STOKES’S THEORY AND PRACTICE OF MEDICINE. whether you shall have recourse to the employment of purgatives or not. If you happen to be called in at an early period, or if the patient has taken no purgatives, and there is reason to suspect a loaded state of the bowels, you will be right in employing some mild laxative. You cannot commence your treatment better than by prescribing some mild opening medicine, particularly when you discover that the patient has been taking indigestible improper food. This plan I think both reasonable and useful. You will frequently meet with cases in which all the bad symptoms will disappear after the use of a few laxatives. Here is a point on which the fol- lowers of Broussais erred. They declared that the exhibition of a single laxative would be to endanger the patient’s life ; and that the only treatment which could be relied upon consisted in the use of leeches, low diet, and cold water. But I think there is as much reason in giving a laxative to remove indigestible matter from the bowels in a case of this kind, as there would be in giving an emetic in a case of gastritis produced by the presence of indigestible mat- ter or corrosive poison in the stomach. But if, after having evacu- ated the bowels, the symptoms of intestinal irritation should con- tinue, you are not to persist in the use of purgatives; change your hand, and attack the symptoms of intestinal inflammation, which have now decidedly commenced. We shall occupy ourselves, gentlemen, at our next lecture, in considering the treatment of this disease in the adult as well as children, and then go on to the disease of the large intestines. LECTURE IX. Treatment of ileitis—Advantage of leeching—Stimuli sometimes beneficial—Infantile remittent fever—Inflammation of the mucous membrane—Enteritis with diarrhoea— Effects of opium in inflammation of serous and mucous membranes—Pathology and treatment of diarrhoea and dysentery—Perforation of the intestine—Diseases of the large intestine. We shall be occupied to-day in considering the treatment of in- flammation of the mucous membrane of the small intestine. You may recollect that in my last lecture I spoke of the employment of laxatives in this disease, and mentioned that we are to employ laxatives in enteritis, on the same principle as emetics are used in cases where corrosive poison has been taken into the stomach. We are not to expect to be able to cure the disease by the use of laxa- tives, nor are we to have recourse to them in every case; we employ these remedies where we have decided evidence of the existence of offending matter in the bowels. We may meet with a case in the early stage, under such circumstances that the removal of the irri- tating matter by judicious purgation may completely relieve the patient, and this, I believe, is the foundation on which the super- TREATMENT OP ILEITIS. 73 struction of the British purgative practice in ileitis and tabes mesenterica was raised. It was concluded that a laxative treat- ment, which had on many occasions succeeded in removing the first symptoms of the disease, would necessarily cure it in all stages and cases. This, I need not tell you, is wrong. Whenever you give purgatives or laxatives in enteritis, bear this in mind, that the effect which you have to produce is to be brought about at the least possible risk. If you can unload the bowels with a little castor oil or rhubarb, or some mild neutral salt, it is much better than to have recourse to calomel, or scammony, or colocynth. As a ge- neral rule, drastic purgatives must be avoided in inflammation of the mucous membrane of the intestines. The school of Broussais committed an error, on the one hand, by never admitting the use of laxatives, and British practitioners have been wrong, on the other hand, by giving too much purgative medicine. The error of the latter arose from looking always upon purgatives as anti- phlogistics, which they are certainly, so far as they contribute to relieve inflammation by causing an increased secretion from the intestinal mucous surface. But this increase of secretion can be produced only by stimulating the organ to which they are applied ; and hence, before they can become general antiphlogistics, they must of necessity be local stimulants. Further; if in a case of inflammation of the digestive tube you prescribe a purgative, and it fails in causing an increase of secretion, it will add considerably to the existing inflammation. It is, however, of very great import- ance that there should be no accumulation of offending matter in the bowels; and hence, when yon find a degree of fulness in the belly, and the dejections scanty, you should always give a laxative, and follow it up by the administration of a narcotic. By using ene- mata, you can do a great deal of good, and this without any injury to the digestive tube; and I think they may be always employed with benefit in disease affecting the ileum. Recollect, gentlemen, what I wish to impress upon you respecting this part of the treat- ment is, that laxatives are to be employed in ileitis as one of the means of cure ; but you are not to expect that a cure by the use of these alone will always be a matter of constant occurrence. It is true that many cases presenting symptoms of enteritis, have, in the beginning, yielded to laxatives; but it is true, also, that horrible mischief has been done by their continued or indiscriminate em- ployment. A few observations now with respect to bleeding. There is in simple inflammation of the mucous membrane of the intestines this peculiarity—it very seldom happens that it is necessary to use the lancet. The whole class of intestinal inflammations is so generally accompanied, even in the early period, with marked prostration and a typhoid condition of the whole system, that general bleeding is very seldom employed. But when the disease is recent, the constitution vigorous, the patient young, the skin intensely hot, and the pain violent, (a combination of circumstances which is not of very common occurrence,) you may employ the lancet with 74 STOKES’S THEORY AND PRACTICE OF MEDICINE. safety and with great advantage to your patient. But what I wish to impress upon you is this—you must not expect to cut short an attack of enteric inflammation by general bleeding. Over inflam- mations of mucous membranes in general, but particularly of the intestinal mucous surface, the lancet has comparatively but little direct power ; it is in the inflammatory affections of parenchyma- tous tissues and serous membranes, that we generally observe the most brilliant and decided effects of venesection. Neither can you, as in parenchymatous inflammation, bleed a second and a third time with benefit. In cases of inflammation affecting the mucous membrane of the intestinal canal, you are to look upon venesection as a preparatory step to leeching. Where the pain is violent, the fever high, the attack recent, and the constitution strong, you will do well to bleed; but only bleed once, and then apply leeches in abundance over ths suffering organ. There is nothing of more importance, nothing of such decided value, as bleeding by leeches in inflammation of the mucous membrane of the intestinal canal, and here we arrive at a fact, the explanation of which is involved in much obscurity. A patient is attacked with inflammation of the mucous membrane, and glands of the digestive tube, twelve or twenty leeches are applied to the integuments of the abdomen, and their application is followed by extraordinary relief. This is a very curious fact when we consider that between the place where we apply the leeches, and the tissue which is affected, there inter- vene skin, cellular membrane, superficial fascia, cellular membrane again, deep-seated fascia, muscular substance, cellular membrane again, two layers of peritoneum, and muscular substance enveloped in cellular tissue. Yet, notwithstanding this extraordinary succes- sion of tissues, it is an undeniable fact, that the application of a dozen leeches to the surface of the belly will frequently cut short an intes- tinal inflammation, or materially diminish its intensity. Here is a fact, the explanation of which is extremely difficult; and I tell you candidly, I cannot explain it. The school of Broussais attempt to explain it as follows. They state that it is a constant law of the economy, that there is a strong sympathy between the internal parts and their respective integuments, but they do not say why this sympathy should exist. We frequently, however, observe facts confirmatory of this law; you are aware that it often happens, that, in cases of the deep-seated muscular phlegmon mentioned by Mr. Crampton, in abscess of the liver, and in empyema, we have a swelling of the integuments, showing the existence of a sympathy between the integuments and the internal organs. In treating a case of inflammation of the small intestine, I think you may generally commence with the application of twelve or eighteen leeches over the ileo-coecal region. The ordinary result of this application is, that the pain and tympanitis are reduced, and the thirst diminished ; but the patient still has fever, and you are to bear in mind that the mere subsidence of pain does not imply the removal of the disease. We may modify the character of an ileitis very considerably by a single application of leeches, but we are not TREATMENT OF ILEITIS. 75 on that account to expect that we shall be able to remove the dis- ease entirely. In general it is necessary to apply them two or three times, lessening the number at each succeeding application, and taking care that they are applied in the proper place, that is mid- way between the umbilicus and the crest of the ileum. Many practitioners are afraid of employing leeches in the advanced stage of this affection, in consequence of the great debility which cha- racterises the advanced stage of this, as well as inflammation of every other part of the digestive tube. But though 1 am quite of opinion that the school of Broussais is wrong in using them at any period, still I think they may be employed even where the disease is advanced, particularly if they have not been used before, and I have frequently seen leeches applied with advantage as late as the twelfth day. I have employed them myself in the Meath Hospital as late as the ninth and tenth days with decided benefit. Many physicians on the continent are in the habit of treating inflamma- tion of the digestive system by the application of leeches to the anus, and this is said to have a very good effect, and the number of leeches required is smaller. In disease of the great intestine ac- companied by diarrhoea, tenesmus, and tormina, I think this is an excellent mode, but when the disease is in the upper part of the tube, I prefer applying them to the belly over the situation of the inflamed organ. Now with respect to internal medicines. In this disease every thing that is administered should be given with the view of re- moving irritation, and for this purpose 1 know no better preparation than a combination of ipecacuanha and opium, as in Dover’s powder. The exhibition of the compound powder of ipecacuanha is attended with decided advantage. You are all aware of the long established use of ipecacuanha and opium in diseases of the intestinal canal, and I think there can be no doubt that they possess considerable utility. With this I generally combine some mild mercurial; the best you can employ is the hydrarg. cum creta. Give two or three grains of each every second or third hour, as the case may be, and you may continue this for several days. Where there is no diarrhoea, and the bowels have a tendency to be constipated, it will be necessary to order, every second or third day, a mild laxative, a little manna, or rhubarb, or some castor oil; you should insist on the daily use of enemata, and if they answer the purpose sufficiently 1 would advise you to be sparing of the use of laxatives by the mouth. In addition to these reme- dies, I am in the habit of giving a considerable quantity of gum Arabic, which appears to have an extraordinary efficacy in dis- ease of the small intestine. I look upon it as peculiarly valuable in the diseases of children. The ordinary mode of prescribing it is to give a certain quantity of gum water. If this is insufficient, you should order half an ounce or an ounce of the gum to be dissolved in a pint or quart of water, which the patient is to use during the day. After the use of the hydrarg. c. creta and Dover’s powder, this has a decided value in the treatment of ileitis. 76 STOKES’S THEORY AND PRACTICE OF MEDICINE. In this way by leeching, mild laxatives, prescribing mercury with chalk, and compound powder of ipecacuanha with gum water, your patient begins to improve. The tenderness of the epigastrium disappears, the tongue begins to clean, the fever diminishes, the thirst goes off, and appetite returns. This is the favourable termi- nation. When the patient is of a weak and delicate habit, it is of great importance to pay particular attention to supporting the strength, even from an early period of the disease. In such a case, after the first week, the physician who neglects the proper means of supporting his patient’s strength does wrong, and it has justly been remarked, that a practitioner will be right in supporting the general strength, at the same time that he is employing local antiphlogistics. It is in steering clear between these two opposite dangers that the judicious practitioner is seen ; he does not allow his patient to die of inanition, while at the same time he takes care to remove local inflammation. I have seen several experi- enced physicians prescribe leeches to the abdomen on the same day that they ordered the patient to have chicken broth, and even a little wine. There is nothing improper in this ; an inexperienced practitioner, who has his eye merely on the local inflammation, is apt to fall into the error of overlooking the constitutional debility, and allowing it to steal upon him. He finds very little difference between the appearance of his patient this day and the next, and thinks the slight increase of debility undeserving of any attention. At last his patient begins to sink visibly, he gets alarmed and has recourse to stimulants, but it is now too late. Besides, there are several articles of diet which support strength, without increasing inflammation ; as, for instance, chicken broth, sago, arrow-root, strained rice, &c. These do no harm, and they prevent the patient from falling into a dangerous typhoid condition. Let us look at this in another point of view. Suppose you are called to a child who is said to have had an attack of worms, or bilious derange- ment, or that his bowels were costive, and purgatives were given, that the discharges were found to be bad, and more purgatives were administered; or suppose you are called to a child of a weak scrofulous habit, who had been taking large quantities of purgative medicine, for what has been termed derangement of the bowels, and you find the little sufferer with pale, shrunken face, a black circle round his eyes, cold extremities, rapid faltering pulse, great thirst, and evident symptoms of increased cerebral excitement; the little arms and hands are cold as death, but the belly burning, tympanitic, and very sensible to pressure, and when you compare the radial artery with the femoral, as it turns over the pubis, you will have some conception of the excited condition of the abdominal vessels ; and in addition to this train of morbid phenomena, you find there is suppression of urine. Are you to attack these symptoms with antiphlogistic means? No; the first thing you are to do, is to prevent any further mischief, by totally inhibiting every kind of purgative medicine. You are next to consider carefully what the best line of treatment to be pursued is, for here you are under TREATMENT OP ILEITIS. 77 circumstances of difficulty, and have a great many prejudices to contend with. What I find generally to be most successful is this. I begin by taking proper steps to support the strength, ordering the patient to take chicken broth, arrow-root, or jelly; the extremities are to be wrapped up in warm flannel ; and if the patient is sink- ing, and has his mouth and teeth crusted with dark sordes, a little wine, watching its effects. If it produces sleep, if the pulse comes down under its use, and the fever is not increased, it will do a great deal of good, and you can gradually increase the quantity. Always bear in mind that there is a certain period in all inflammations, in which stimulants prove to be antiphlogistics, a circumstance which has been overlooked by the school of Broussais. So far with re- spect to constitutional treatment; but what will you do with local disease? The application of blisters is of decided use, nay, I have seen a few leeches very effective. Apply a blister to the abdomen, and dress it with mercurial ointment, at the same time you may employ frictions with mercurial ointment; you will also swathe the belly with flannel, so as to keep up a comfortable temperature. In this way you will be able to do a great deal of good. You will also prescribe hydrarg. c. creta, with Dover’s powder ; and if the bowels are confined, emollient injections. By steadily pursuing this plan of treatment, you will often rescue from imminent danger a case which would prove fatal under the purgative plan, and you will add greatly to your own reputation. There is one form of this disease in which diarrhoea is a promi- nent symptom, where the purging is from the very commencement. On this form I am anxious that you should have clear ideas. In cases of this kind there is a copious discharge of fluid matter from the bowels. In the majority of cases you may lay down this law, that where there is a decided irritation of any secreting organ, in- creased discharges from the surface of that organ give more or less relief. Suppose two cases of hepatitis ; in the one we have no secretion of bile, in the other the secretion is copious; the latter is certainly most favourable. Again, suppose two cases of bronchitis ; in one there is a copious expectoration, in the other it is extremely scanty; now every medical man knows that the former is more easily managed. The increased secretion of any organ in the early stage is to be looked upon as a relief to the inflammation. The practical inference to be deduced from this is, that we should be cautious in adopting any means of arresting this discharge, as it is one of the modes which nature employs in relieving the irri- tation of a suffering organ. Well, then, suppose you have a case of enteritis, and that on the first or second day diarrhoea sets in, what does the routine and systematic physician do ? He gives chalk mixture and opium with tincture of kino and catechu, and what is the consequence ? The belly becomes tympanitic; the pain is increased, and even peritonitis may supervene ;—this is one result of the increase of inflammation ; or the breathing becomes difficult, and the patient gets bronchitis or pneumonia. Diarrhoea occurring in the early period of this-disease is not to be interfered 78 STOKES’S THEORY AND PRACTICE OP MEDICINE. with, except when it gets to such a height as to threaten the pa- tient’s life ; and where it increases his sufferings by the frequency of the discharges. In the first week or fortnight, when there are only three or four discharges, or even five in the twenty-four hours, I believe it is better not to interfere by prescribing direct astringents; but in the advanced period, when the powers of life are low, or the discharges very copious, then the physician comes to the assistance of nature with just reason, and in such cases you should always interfere. The best mode of managing diarrhoea of this kind is to employ small, frequently repeated doses of Dover’s powder, with anodyne injections. And here I may mention briefly, to such of you as have not seen them used, the best way of employing them. As these injections are used on a different principle from the com- mon, the latter being intended to empty the great intestine and be discharged, the former to be retained, we are constantly to make the basis of our anodyne injection in such a manner, that it will not prove stimulant from its bulk, or from any irritating substance it may contain. Mucilage of starch, new milk, or linseed decoc- tion may be used as the basis, and the quantity taken for one injection should never exceed three ounces. To this, for an adult, you add from fifteen to thirty drops of tincture of opium, for it is a curious fact connected with this subject, that opium given by the rectum has frequently been observed to exercise a much more pow- erful effect on the system than when an equal or even smaller quantity has been taken by the mouth. The rule then is, that when you first make trial of the remedy in this manner, feel your way cautiously, and if you find that your patient bears ten or fifteen drops, you can increase the quantity on repeating the enema. An eminent practitioner of this city thinks the narcotic effect of opium by the rectum much better marked than by the mouth, and I believe this to be true in many instances. I believe the adminis- tration of opium in this way requires a good deal of caution. I recollect the case of a man who had been for a considerable length of time in the habit of using laudanum in large quantities, and was, in fact, a regular opium eater. During an attack of illness he got an injection containing sixty drops of laudanum; this pro- duced, in a very short time, symptoms of decided narcotism, from which the patient never recovered; in fact, he died with every appearance of being poisoned by opium. There is another fact with respect to this disease which I would have you to bear in mind, that, under certain circumstances, inflammation of the small intestine will produce a remarkable tolerance of opium. This ap- plies not only to the advanced stage of enteritis, but also to many other forms of disease. Some time since I made a series of clinical experiments with the view of ascertaining the power which opium possesses in relieving inflammation, and the result has been, that in many cases where the powers of life are so low that we cannot have recourse to the lancet, or any kind of depletory measures, opium alone furnishes us with a powerful means of subduing inflammatory action. When we come to treat of peritonitis, I shall TREATMENT OF ILEITIS. 79 have occasion to speak of the good effects of very large doses of opium, particularly in that form of disease which results from intestinal perforation. My first trials of this remedy were in affec- tions of serous membranes, and to this I was led by some interest- ing clinical experiments made by Dr. Graves. I next, tried it in diseases of mucous membranes, where antiphlogistics were inad- missible, and here, as in the former cases, I had many proofs of its great efficacy. I shall state the particulars of a very remarkable case. A young gentleman, a pupil of mine, and a member of the class at Park street, of an irritable habit, was attacked with intense inflammation of the mucous membrane of the intestines. He had a high degree of fever, and his thirst was so insatiable that for two days he never ceased calling for drink. His pulse was weak but rapid ; his tongue red and pointed ; respiration very much hurried; but the stethoscopic signs of disease of the lung were absent. His belly was exceedingly tender on pressure; and he had another remarkable symptom—constant smacking of the lips. The case, as you may perceive, was one of severe gastro-enteritis, and it was treated in the ordinary mode, by leeches, cold water, &c., but the disease showed great obstinacy, and at the end of a month the pa- tient was evidently in a state of imminent danger. At this period a curious revulsion took place: the chest became engaged, and the patient got bronchitis. For this he was blistered, and took the decoct, polygalae with large doses of carbonate of ammonia, under the use of which he recovered. The bronchitis disappeared, but was almost immediately replaced by symptoms of intense gastro- enteric inflammation, thirst, quick pulse, tympanitis, low delirium, and subsultus tendinum. In the course of two or three days diar- rhoea come on, becoming more profuse as it advanced. The first day he had four discharges, the next eight, and thus it went on increasing until there was a constant discharge of thin fluid matter from the anus. The patient was quite run down, and on three different occasions his friends thought him dead. Having made an unsuccessful trial of various stimulants and astringents, I deter- mined to try what might be expected from large doses of opium. The patient was dying, and it was necessary to do something instantly which would be likely to arrest the diarrhoea. I ordered a grain of opium to be given every hour; on the first day he took twelve grains with apparent benefit, the next day he took six, the same quantity on the third day, and on the fourth the diarrhoea had so much diminished, and the young gentleman was so much better, that I thought it might be safely omitted. From this period my patient recovered rapidly. I would not bring forward this case in proof of the efficacy of opium if there were not many others of a similar kind ; and I have no doubt that this was a cure effected by the use of opium in large doses. In the treatment of this disease by opium, there is one simple rule, by observing which you will be able to avoid all difficulties, and at the same time have a criterion to judge of the value of the opiate treatment. If the remedy pro- duces the ordinary narcotic effects of such large doses on the 80 STOKES’S THEORY AND PRACTICE OF MEDICINE. system, it will not do much good. You begin, therefore, cautiously; and if, after the first or second dose, you find that decided nar- cotism is produced, or at least more than you would think the quantity given could have brought on, give it up—it will be dan- gerous. liut if he bears one, two, or three grains, or if, after having taken six or eight grains in the twenty-four hours, he appears to be improving, you may then persevere in the administration of opium, and it will be attended with decided advantage. We have next to proceed to the consideration of the pathology and treatment of diarrhoea and dysentery; I shall, however, first exhibit a few preparations illustrative of the diseases of the small intestine. Here is a preparation of the affection called tabes me- setiterica. You see here various masses of those cheesy glands which are generally supposed to be the result of original scrofulous deposition ; but if you look along the folds of the intestine, you will see a vast number of engorged lymphatics running up directly to those glands, and you will perceive that these lymphatics cor- respond at their commencement with ulcerative disease of the intestinal mucous surface and glands. Here is an interesting preparation, exhibiting three distinct ulcers. In one of these you see the bright vascularity and turgescence of the areola, and the ulcerative process which has just begun in the centre. Close to this is another large ulcer, which has destroyed the texture of the gut down to its serous covering, through which you perceive the light is shining. The last is an example of perforating ulcer ; all the coats of the intestine have been destroyed, and on turning the preparation you see evident marks of peritoneal inflammation. This preparation also exhibits one of the modes in which an ulcerative perforation of the intestine may terminate. Sometimes, at the very moment the ulcerative process has succeeded in de- stroying the last coat of the intestine, inflammation of the serous membrane in the immediate vicinity takes place, a quantity of lymph is poured out, and if the matter be not in great quantity, and the hole not too large, the opening is closed up by the effused lymph, and a stop is put to further mischief. Again, by the effu- sion of lymph the ulcerated portion of the intestine may form an adhesion to another sound portion, the effused lymph does not permit the passage of the contents of the intestine into the perito- neum, but does not prevent them from getting into the sound portion by a continuance of the ulcerative process, and in this way we have another termination, in the formation of a false passage. Here is a good example of disease of the ccecum, here is an exam- ple of disease of the colon, and here is another with a vast number of ulcerations. Here is an interesting specimen of disease of the large intestine. The patient to whom it belonged died of phthisis;— look at it and you will see what extensive ravages have been made by the ulcerative process. We come now to take up the subject of disease of the large intestine, which, as I find my time nearly past, I must reserve until our next meeting. I shall then speak of dysentery and diarrhoea, DISEASES OF THE LARGE INTESTINES. 81 and shall draw your attention to some new and curious facts respecting the discharge of fatty matter from the bowels. In the last number of the Medico-Chirurgical Transactions, three separate papers have appeared on this subject from Dr. Elliotson, Dr. Bright, and Mr. Lloyd. Dr. Bright has brought forward several interesting facts tending to show that discharges of fatty matter may be found to be indicative of certain forms of disease of the digestive tube and the neighbouring glands. LECTURE X. Diseases of the large intestines—Treatment of diarrhoea—Apyrexial period of diarrhoea —Danger in suddenly arresting the discharge—Purging in phthisis—Dysentery— Epidemic dysentery. To-day we proceed to the consideration of the nature and treat- ment of some of the diseases of the large intestine. You will see, in the various systematic treatises on the practice of physic, sepa- rate descriptions of the aifections of this portion of the digestive tube, you will find diarrhoea in one chapter and dysentery in another, and you will observe, that a great deal of ingenuity has been expended in forming nosological differences between these affections. I fear that much of what has been written respecting them is rather calculated to puzzle and mislead than to inform the student. Viewed anatomically, there is no essential difference. You may for every practical purpose place them in the same class, and consider them as the result of the same morbid condition of the same part, namely, an inflammation of the lower portion of the digestive tube. Some persons may quarrel with the term inflam- mation—call it, then, irritation, if you please ; but the truth is, that it is a disease of the lower portion of the intestine, the results of which are increased sensibility and altered secretion ; and this description, I think, will fairly apply to one as well as the other. If a man has purging, with fever and pain, it is called dysentery; if he has purging, without pain, and without any manifest febrile excitement, we call it diarrhoea. But, in cases where persons have died, after having laboured under diarrhoea for a length of time, we generally find, on dissection, lesions of the mucous membrane of the intestinal canal, sufficient to account for death. There are some cases, indeed, in which the mucous surface takes on a gleety discharge, similar to that which follows gonorrhoea, and under such circumstances you will not be able to discover any distinct anatomical evidences of disease. These, however, are compara- tively rare, and bear little or no proportion to those cases which present distinct traces of organic lesion. On the subjects of diarrhoea and dysentery I shall be very brief, as our time is short, and every thing relating to the pathology and 82 STOKES’S THEORY AND PRACTICE OP MEDICINE. treatment of these affections may be expressed in very few words. First, then, as to diarrhoea, which is the frequent passing1 of stools of a more or less watery consistence, and which may, and gene- rally does, occur without fever. This affection may be considered to arise under three different circumstances; but, in point of fact, every form of the disease may be referred to a single cause, as there is no essential difference in the actual nature of the circum- stances by which they are produced. A patient, for instance, takes a quantity of indigestible food, this produces irritation in the gastro-intestinal mucous surface, and diarrhoea is the consequence. Another is exposed to cold, or gets wet feet, the mucous membrane of the bowels becomes more or less inflamed, and this terminates in diarrhoea. Again, a patient, labouring under hectic, has profuse perspirations, these go off' and are replaced by frequent fluid dis- charges from the bowels—here, also, the result is called diarrhoea. All these forms are, however, referable to the same cause—irrita- tion of the mucous lining of the digestive tube. A man commits an excess at table, eats something that he cannot digest, and gets diarrhoea. If you happen to be called to such a case at an early period, your course is very plain and easy ; there is every chance that the affected organ has received (as yet) no material injury, and is attempting to relieve itself by increased secretion. The indication here, is to get rid of the source of irrita- tion as soon as possible, and this is best done by prescribing a laxa- tive, to remove the offending matter, and then following it up with an opiate. The simple rule is to relieve the intestine, and prevent the liability to inflammation. A mild laxative, followed by opiates and demulcents, keeping the patient on a low regimen for a few days, and in a warm temperature; this is sufficient for the manage- ment of the first form of diarrhoea. In point of fact, the principal thing which the practitioner has to do, is to watch his patient, and take care not to permit the inflammatory action to become developed. It is in such cases as these that the expectant medi- cine is of value. What you are to direct your attention to, is the state of the intestinal surface. If a patient gets an attack of pain, if his belly becomes tender on pressure, if he is more or less feverish, you may be sure there has been some mischief done. If, on the contrary, the diarrhoea yields to the exhibition of a mild laxative and light diet; if the pulse be soft, and the belly not tender, you have no reason to fear. But if the purging becomes more dis- tressing, if the pain is severe, the abdominal tenderness evident, the thirst and restlessness continue unabated, it is a sign that the irri- tation has produced something more than mere increased secretion, and that actual disease of the mucous tissue is setting in. We have now a true inflammatory diarrhoea, which may be looked upon altogether as an enteritis of that kind in which there is a copious secretion from the surface of the intestine. You observe this leads us at once to the principles of treatment. Here we have fever, pain, frequent morbid stools, thirst, and abdominal tender- ness. Well, then, what are you to do ? In a case where these DISEASES OF THE LARGE INTESTINES. 83 symptoms are so severe as to excite alarm, at once begin with applying leeches. Where there is merely evidence of intestinal irritation, caused by indigestible food, give a laxative, and follow it up with an opiate; where, in addition to the ordinary symptoms, you have fever, pain, and tenderness, never omit the application of leeches. Many a time have I seen cases of this kind, in which chalk mixture and astringents not only failed but even caused additional suffering, speedily and completely relieved by the appli- cation of a few leeches. In using leeches, too, we are not like the practitioners who trust to astringents, playing at the game of double or quits ; nor do we stop the purging by exchanging it for something else equally bad, or even worse, for a peritonitis or a bronchitis, for instance ; by removing its cause we not only check the diarrhoea, but we obviate any tendency to a metastasis of inflammation to other tissues, and our mode of cure has at once the merit of being successful and safe. A patient who has had an attack of diarrhoea should have his belly swathed with flannel; this should never be neglected. He will also experience a great deal of benefit from the use of the hip bath and occasional opiates. Give, also, a combination of rhubarb and Dover’s powders, and you will find that it will do him a great deal of good. This is the remedy which Rhaederen and Wrngler found to be of extraordinary advantage in the mucous fever, with diarrhoea, which ravaged parts of Germany in the last century. Give two or three grains of each every second or third hour, and increase or diminish each of the ingredients according to circum- stances, increasing the Dover’s powder where the indication is to remove pain and irritation, and increasing the rhubarb where you wish to produce a laxative effect. This combination forms a remedy of decided value in enteric inflammations; it has been much used in such cases by Dr. Cheyne, and I have repeatedly employed it in the Meath Hospital with marked advantage. You are also to bear in mind, that though the principle of treatment in this disease is to remove its cause and put a stop to the purging, still you are in no case authorised to give it a sudden check, by astringents, in the early period. I gave the reasons for this at my last lecture, and showed that it was based upon a general law of the economy. If an organ in a state of inflammation pours out an increased quantity of secretion, it is the mode in which nature attempts to give relief; and if you suddenly arrest this secretion, the probability is, that you will excite more inflammation in that organ, or cause a metastasis to other parts. This is particularly the case if inflammatory fever exists. You must also attend to your patient’s diet. Your object here is to support him on such a diet as will require but little digestive power, and will not produce large collections of faecal matter in the bowels. Jellies, arrow-root, chicken-broth, and mild farinaceous food, are the only things that can be used with safety, until the intestinal irritation has subsided. By pursuing this plan of treatment with steadiness and decision, you generally succeed in cutting short the disease. In some cases, 84 STOKES’S TIIJEORY AND PRACTICE OF MEDICINE. the diarrhoea will ran on to the chronic stage, just like the gleet which follows gonorrhoea; and this is to be looked upon as the apyrexial period, in which antiphlogistic remedies are no longer admissible, and where you may employ stimulants and astringents with effect. The best way to manage this form of the disease, is to make your patient use warm clothing, an even temperature, and mild nutritious diet; to prescribe the vegetable and astringent tonics, the hip bath, and the occasional use of mild laxatives, followed by an opiate. In this way, after some time, the disease generally goes off, and the patient recovers his strength. But it may happen that this gleety discharge will continue unabated ; it is running the patient down, and he wants some decided remedy to check it. Now, the remedies which appear to have the greatest power in stopping this discharge, are the metallic astringents, and the turpentines and balsams, combined with some of the prepara- tions of opium. It is a curious and interesting matter to consider how these remedies act. They are a class of medicines which exercise an extraordinary influence over discharges from mucous surfaces, in a way we do not understand, but the effect is to arrest these discharges. In a case of ophthalmia, accompanied by copious secretion from the conjunctiva, or in a case of chronic gonorrhoea, we know there is nothing more beneficial than metallic astringents and balsams; and we are also aware of the great value which tur- pentine and balsam copaiva possess in checking the increased expectoration of a chronic bronchitis. In diarrhoea, also, they have the same power; they check inordinate secretion, and remove the morbid condition of the mucous membrane on which it depends, by some effect produced on the surface of that mem- brane, but in what manner this is accomplished we know not. In severe cases of this gleety discharge, one of the most certain remedies we can employ is acetate of lead. You will seldom have occasion to use this, or any of the other remedies alluded to, in the case of a healthy person, because the disease will seldom pass into this second or gleety stage ; but if it should, and that it is running down the patient, it behoves you to check it as soon as possible, consistent with safety. Give, then, the acetate of lead in free and repeated doses, and it is singular to remark what quantities of it patients under such circumstances will bear without any bad con- sequence ensuing. Hitherto, many persons have been afraid to employ it in large quantities, from fear of producing painters’ colic; but at present it is known that this disease is to be attributed to the absorption of the carbonate of lead in almost every instance, and that the acetate is comparatively harmless. On this point I can mention one interesting fact, namely, that I have been in the habit of using it constantly, and in considerable doses, for the last six years, and I cannot bring to my recollection one single instance of colic produced by it. One patient, in particular, who was under my care, took it in very considerable doses for six weeks, without any apparent injury. The only cases in which I have seen the acetate of lead act as a poison, were those in which it had been DISEASES OF THE LARGE INTESTINES. 85 used as an external application. Whether it be that this remedy is more pernicious when employed after the endermic mode, or whether, when applied to the skin, it attracts carbonic acid from the air, and is converted into a carbonate, I do not know, but of this I am certain, that where bad effects have followed the employment of the acetate of lead, they have been brought on it by its external use. I generally use this remedy in the form of pill, prescribing two grains of the acetate of lead and a quarter of a grain of opium, three times a day. With the same intention you may employ the turpentines and balsams, which have a powerful effect in checking mucous discharges. Dr. Pemberton, in his work on Abdominal Diseases, speaks very highly of the efficacy of balsam copaiva; and I have seen many cases where turpentine has had a great efficacy in arresting chronic diarrhoea. You will see, in the works on materia medica, some other remedies which you can employ with benefit in such cases, but I may mention one which is not generally known—the alkali of the nux vomica. Strychnine was first used in checking mucous discharges by a German physician, and afterwards by Dr. Graves in this city. The cases in which it proves most successful, are those in which there is a mere gleety discharge, a copious secretion from the mucous surface, without any inflammatory action whatever, or if there be, where it is so low as not to produce the least feverish excitement or pain. Cases of this kind, in which strychnine has been eminently suc- cessful, have been published by Dr. Graves.1 Among others, is that of gentleman, who had sudden calls, so that he often had not time to reach the close-stool. He passed a quantity of thin jelly- like substance, and then experienced a transient relief until another attack came on. This case was cured by the use of strychnine, one twelfth of a grain, three times a day, made into pills with crumb of bread or aromatic confection. I may mention here, that, in treating gleety diarrhoea in this way, one thing should be always borne in mind—it is always dangerous to check any copious secretion suddenly, and the danger consists in the liability to metastasis or new inflammation. Never forget this. What generally happens is, that the patient’s belly begins to swell, and you have ascites rapidly formed. Now, I have never seen a case do well in which this kind of ascites came on after the sudden checking of a diarrhoea; the patients all died. Another consequence is the rapid supervention of pulmonic inflammation, and here the disease is almost as bad as in the bowels. You will ask how this unfavourable termination may be avoided. The best mode is, while you are arresting the discharge from the bowels, to promote a determination to the surface. While you are using opiates, and stimulants, and astringents, employ general warm bathing, or the hip bath, dress the patient in flannel, 1 Tn similar affections it has been used successfully by Professor Gedding, of South Carolina. We have often given it, sometimes apparently with success, at others not.—R. D. 86 STOKES’S THEORY AND PRACTICE OF MEDICINE. and use mild diaphoretics every night. You will also do right in blistering the belly occasionally. In this way you will succeed in curing the worst cases of this chronic flux, without exposing your patient to the risk of new inflammation, or translation of disease to other organs. One of the most common forms of diarrhoea is the purging which occurs in cases of phthisis; a physician will be called to treat this as often as any other, and it is of importance that you should have correct ideas with respect to its pathology and treatment. The ordinary opinion is, that this kind of diarrhoea is one of the results of hectic fever, and many practitioners, in treating the purging of consumptive patients, overlook the actual condition of the intestine, and only take into consideration the state of the whole constitution, of the hectic state of which the diarrhoea is looked upon as one of the symptoms. The consequence of this is, that they do not pro- ceed on the same principles in the treatment of this as of other similar affections of the intestinal canal. Now, I would impress upon you, that you should always consider the diarrhoea of phthisis as depending, in almost every instance, on enteric inflammation. There is no fact in medicine better established than this. Persons think it is the hectic which produces the purgation, but I believe the converse of this proposition is often much nearer the truth, and that the constant diarrhoea often produces and keeps up the hectic. If you examine the digestive tube of a patient who has died with symptoms of phthisical diarrhoea, you will commonly find extensive ulcerations in the colon, coecum, and ileum. In some cases of consumption, where the purging has been very severe, the amount of disease will often be found to be quite extra- ordinary ; I have often seen the whole of the lower part of the tube one sheet of extensive ulceration. I find I have not brought up any specimens of the effects of phthisical diarrhoea from the museum, but will exhibit them at our next meeting. The prepa- rations before us are those which are illustrative of dysentery, but they will convey to you a good idea of the state of the great intes- tine in the diarrhoea of consumption, for the effects are nearly the same. Observe now, the importance of this fact, and recollect that in treating every case of consumption, with diarrhoea, you will have constantly to bear in mind this enteric complication. Recol- lect, also, that one of the best means of stopping it, when all other remedies have failed, is a blister applied over the abdomen. If the purging depended on hectic, this would not be the case. I could bring forward several cases in which every thing had been tried without success, when a blister was applied to the belly, and from the time it rose, the patients ceased to be troubled with diarrhoea, and continued so up to the period of death. I do not mean that you should in these cases proceed to attack the enteritis with the same vigour as you would a similar disease in the healthy subject. Generally speaking, I believe this form of enteritis to be incurable ; but it is of importance that you should be aware of this enteric complication in phthisis, and when you are called in to treat such DISEASES OF THE LARGE INTESTINES. 87 a case, you should carefully avoid prescribing any thing calculated to add to the existing irritation. Before I quit this subject, I wish to make one remark by the way of caution. It not unfrequently happens that a person, labouring under chronic diarrhoea, comes to consult a medical practitioner, and tells him that he has been suffering from this complaint for months, that he has eight or nine discharges by stool in the day, and that he has been under the care of five or six doctors in suc- cession, without any benefit. Well, you are determined to have your trial, too, and you commence operations by putting him on full doses of acetate of lead. After a week or a fortnight, he comes back and tells you he is not a bit the better. You then try turpen- tine or balsam copaiva—no use. Nitrate of silver—the same result. The man get stired of you in turn, and perhaps goes to a surgeon to ask his advice. The surgeon examines the rectum carefully, and finds, at a short distance from the anus, an ulcer, which he immediately touches with a strong solution of the nitrate of silver. The ulcer begins to heal, the irritation of the gut ceases, and the diarrhoea goes off. The surgeon is extolled to the skies, and the doctors disgraced for ever in the opinion of the patient. Now this is not an uncommon case. I have seen several instances of it, and I must tell you I was once mistaken in this way myself. These ulcers are situated close to the verge of the anus ; they occur chiefly in persons of broken-down constitution, and those who have taken a great deal of mercury. They produce irritation in the colon, tenesmus, griping, frequent discharges by stool, and, most commonly during the straining, a little blood is passed. During the course of last summer, I treated a soldier for this affec- tion, who had been discharged from the East India Company’s service (as was stated in his discharge) for incurable dysentery. I examined the rectum, and finding some ulcers close to the anus, had them touched with the nitrate of silver. Under this treatment a rapid amendment took place, and in the space of three weeks the man was discharged, quire cured. Now, are you to make this examination in every case? I believe you will act rightly in doing so in every case of chronic diarrhoea in the male, but the examination is absolutely necessary in all cases under the following circumstances : first, when the diarrhoea has been of long standing; secondly, when it has resisted a great variety of treatment; thirdly, when it has been combined with tenesmus and a desire of sitting on the night-chair after a stool has been passed, showing irritability of the lower part of the great intestine; and, lastly, when the patient’s health does not appear to be so much affected as it natu- rally should be, where there was long-continued disease of a large portion of the great intestine. A patient will come to consult you, who will inform you that he has had eight or ten alvine evacua- tions every day for the last six months, and yet he eats heartily and looks quite well. Under these circumstances, the cause of the diarrhoea will generally be found to be ulceration of limited extent low down the tube, and capable of being quickly and effectually 88 STOKES’S THEORY AND PRACTICE OF MEDICINE. removed by a strong solution of the nitrate of silver. I shall recapitulate all the circumstances under which an examination is indispensable ; where the symptoms have been persistent, have resisted a variety of treatment, are accompanied by tenesmus, and where the injury done to the general health is not in proportion to the duration of the disease. I may mention here, that a medical friend of mine has communicated to me the particulars of another case of this form of diarrhcea in a soldier who was invalided on this account, and who experienced sudden and permanent relief from the application of nitrate of silver to some ulcerated spots which were discovered near the termination of the rectum. We come now to the subject of dysentery. I shall draw your attention briefly to the general principles of the pathology and treat- ment of this affection; but I do not intend to enter upon the con- sideration of its general history, which you will find sufficiently detailed in books. The first principle I have to enforce on this subject—and you may take it as an observation based on the soundest pathology—is this, that dysentery is inflammation of the large intestine. In some cases it is complicated with fever, and in others with disease in the upper portion of the digestive tube; and I believe that those cases which are termed epidemic dysentery, are those in which this disease is combined with typhus fever, or with an extensive affection of the small intestines—where there is ileitis as well as colitis. I shall not take up your time with discus- sions respecting epidemic dysenteries, or those of warm climates; it will be sufficient, for the present, to allude to that form of disease which is observed in this country. I have told you that dysentery is an inflammatory affection of the great intestine, and all the symptoms during life, as well as the phenomena revealed by dissection, tend to confirm this view of the subject. We often have fever, because the constitution sympathises with the inflammation of an important organ; we have excessive pain and irritation of the intestine, in consequence of its muscular fibres being involved in the inflammation; and we have discharges of morbid, purulent, and bloody secretion. You will now please to inspect this preparation, and hand it round. See the effects of dysentery—the extensive inflammation, ulceration, and sloughing, of the mucous membrane. Here is another preparation ; you per- ceive the whole surface of the colon is covered with coagulable lymph, which, in some cases, forms a chief part of the dejections. Here is a preparation which exhibits extensive sloughing of the mucous membrane; its tissue, you see, is quite abraded and destroyed. Here is a preparation of chronic dysentery, which pre- sents a very curious appearance; the mucous membrane is finely mamillated, as it were, and it is stated on the label, that the process of cicatrisation was going on. If you compare it with the others, you will find a remarkable difference. Here is another specimen of dysenteric destruction. Here, then, is a disease in which we have violent inflammation of the mucous membrane and submucous cellular tissue, and, in SPORADIC DYSENTERY. 89 severe cases, I believe, of all the coats of the great intestine, except the serous. Let us rehearse its symptoms briefly. Fever of an inflammatory or typhoid character, great pain and excessive irrita- bility of the great intestine, morbid discharges of purulent, bloody, and lymphy matter, twisting pains called tormina, and frequently the absence of fecal matter in the dejections. At my next lecture I hope I shall be able to finish this subject, and I shall then bring before you some remarks on constipation and collections of air in the great intestine, two points upon which much light has been lately thrown. LECTURE XI. Sporadic dysentery—Nature of this disease—Treatment; mercurial, stimulating, antiphlogistic—Recommendation of Dr. Elliotson—Success of Dr. O’Beirne in the use of tobacco injections—Tympanitis, or meteorism—Windy colic, remedies for the cure of. I drew your attention briefly, in my last lecture, to the subject of dysentery ; I stated that its anatomical character is now known to be inflammation of the great intestine, and gave it as my opinion, that, in many cases of the epedemic, disease of the large intestine occurs under one of two conditions, either as secondary to typhus fever, or with an extension of the inflammatory process into the small intestine. These circumstances should, I think, be always taken into consideration in cases of epidemic dysentery; but the ordinary sporadic dysentery of this country, which we have now to consider, is, generally speaking, an inflammation of the large intestine. The old doctrine on this subject was, that dysentery was the result of an irritation caused by the presence of scybafe in the colon ; and the indication was to attempt their removal by purgatives. You will find this opinion put forward in many of the older authors, and that the plan of treatment which they recom- mend is in perfect accordance with their notions of the disease. It is a very curious fact, however, that in this country these hard faecal masses, or scybalae, are very seldom met with in cases of dysentery. During the epedemic of dysentery, which occurred in Ireland in 1818, a series of clinical investigations was made on an extensive scale by Dr. Cheyne, who at that period had charge of the Hardwicke Hospital; and he states, that on a strict examina- tion of the discharges in a vast number of cases, no scybalae could be discovered; and in the sporadic cases, which we receive from time to time into the Meath Hospital, I have never found that the patients passed them. It is a great error to think that dysentery depends on the presence of scybalae ; the notion is now shown to 90 STOKES’S THEORY AND PRACTICE OF MEDICINE. be founded on a false pathology, and the treatment which it incul- cates decidedly bad. You will be convinced of the latter when you recollect that the disease is inflammation of the great intestine, that its effect is to throw the muscular fibres of the gut into violent and painful contractions, and that the existing mischief must be therefore greatly increased by the exhibition of strong purgatives. For a knowledge of the true and scientific treatment of this disease, we are indebted to the light which modern pathology has shed upon practical medicine. We now employ purgatives with extreme caution, we use general or local bleeding, according to the urgency of the case ; and we treat the disease as an inflammatory affection of the lower intestine demanding active depletion. All writers are unanimous in recommending the employment of the lancet, in cases of acute inflammation ; and acute dysentery is one of those cases in which general bleeding seems to have the best effect. Dr. Cheyne states, that in this disease the most decided relief resulted from the use of the lancet. He says that in several cases in which there were excessive pain and tormina, and in which nothing was passed for several days but mucous and blood, as soon as venesec- tion had been performed, the patients became comparatively easy, and passed large quantities of feculent matter. He also found that the blood drawn was buffed and cupped; and states that his experience led him to conclude that this disease was best treated by the lancet. Dr. Mackintosh, who has had great experience in dysentery, says, that laxatives will act with the best effects when blood-letting has been premised. In fact, the utility of general bleeding in dysentery is established beyond any possibility of doubt; and those who object to the use of the lancet object to it on theo- retical and not on practical grounds. As a proof of this, you will see a great many cases in which decided relief is obtained by a natural hemorrhage from the bowels; and this I think ought to be sufficient to overcome the doubts of those who are skeptical as to the value of general bleeding in acute dysentery. Next to bleeding, the best thing you can have recourse to is the free application of leeches, a practice not sufficiently appreciated or followed in this country. I would advise you to apply leeches freely along the course of the colon ; and if the tenesmus be con- stant and distressing, round the anus also. The case in which the application of leeches round the anus is attended with the greatest relief, is that in which the tormina and tenesmus are ex- cessive, and in which a quantity of blood is found blended with each discharge. After you have applied the leeches, I would strongly recommend you to direct your patient to sit in a hip bath for some time, and you will find that he will experience great relief, because the bath will act as a fomentation, and promote the flow of blood from the leech bites. I have often seen the application of a dozen leeches round the anus, followed by the hip bath, attended with the most rapid and signal advantage in dysentery. Many persons are in the habit of giving small doses of some mild saline laxative in this affection ; of this practice I cannot SPORADIC DYSENTERY. 91 speak much from experience, and I think more benefit will be derived from the free use of demulcents, gum-water, whey, barley- water, and linseed tea. But the internal remedies on which we chiefly rely in the treatment of dysentery, are mercury and opium. Blue pill and Dover’s powder are an excellent combination, so are calomel and opium, and you may give either of these remedies alternately with a mild laxative, whenever you are led to suspect an accumulation of faecal matter in the bowels. In very bad cases it will be necessary to continue the mercury until the mouth is affected; but in the sporadic dysentery of this country you will very seldom be under the necessity of bringing on actual sali- vation. Permit me here, gentlemen, to make a few observations on mercurial aption. In treating a case of dysentery, it does not, in the first place, follow as a matter of course, that you will cure your patient by subjecting him to the full influence of mercury. You are not to expect that salivation will be always attended with suc- cess. There is another point which should never be forgotten, although it is one which I believe has not been sufficiently consi- dered. It is a common idea with respect to the administration of mercury in cases of local inflammation, that if you produce saliva- tion you do a great deal towards accomplishing a cure, and this is true in most cases. Many persons are of opinion that it is the ptyalism which carries off the disease, and hence it is that we so often see the principal share of a practitioner’s attention directed to produce salivation at all hazards. This is the history of the medical treatment ordinarily pursued in warm climates, where such vast quantities of calomel are given. Here the idea seems to be, that the disease is to be subdued by salivation alone, and accordingly the practitioner “throws in” mercury, an expression evidently arising from the enormous quantities given. There are many cases on record in which eight hundred and even one thou- sand grains have been given for the cure of a single local inflam- mation. But it is remarkable, that in several cases in which vast doses have been given, no ptyalism has been produced, and thus it frequently happens, that the practitioner goes on increasing the quantity, lest he should have failed in consequence of not having given enough. All this practice is wrong and founded on false notions ; and I think that when you come to practice yourselves, you will be inclined to adopt the opinion, that, in cases in which mercury has been employed in the treatment of local inflammation, salivation is to be looked upon more as the result of the relief of inflammation to a certain degree than as its primary cause. For instance, suppose you are called to treat a case of acute enteritis or hepatitis ; you give ten grains of calomel two or three times a day, and find that day after- day passes without any appearance of salivation. Another practitioner is called in, who bleeds the patient, and this is almost immediately followed by the appearance of salivation and relief. My friend, Staff-Surgeon Marshall, who is intimately conversant with the diseases of India, has informed 92 STOKES’S THEORY AND PRACTICE OF MEDICINE. me that he has never known a case in which abscess actually formed in the substance of the liver, in which salivation could be produced ; and that when the patient became salivated, be believed it to be a proof that there was no inflammation of an intense cha- acter, or that no abscess had formed. The greater the intensity of the disease, the less was the chance of salivation occurring, so that the salivation in certain cases appears to be the result of the same influence which produces a relief of inflammation, and not the cause of that relief. When, therefore, you have given mer- cury in free and repeated doses for twenty-four or forty-eight hours, and find no sign of salivation appearing, you should be cautious how you proceed, because in such cases the inflammation may be of that intense character which will not permit the mouth to be affected. Under such circumstances, the use of mercury, if rashly persevered in, will only aggravate the disease. In many cases of intense pneumonia, you will find that the patient will not be salivated until an advanced period, when, in consequence of the subsidence of intense irritation, the mercury is, as it were, allowed to produce its effect on the salivary glands. You may also fre- quently observe instances of intervals between the salivation, in which, during the course of an inflammation, the patient’s mouth becomes affected by mercury; but if he gets fresh symptoms of the original affection the salivation disappears, and returns only when the new attack has been overcome by appropriate treatment. I think that, under these circumstances, we are authorised in consi- dering salivation as the effect of a certain degree of reduction of inflammation, and not as its cause. You will see the importance of these observatians when you reflect in how many cases of local inflammation practitioners are in the habit of trusting to calomel alone ; not being aware of the fact, that inflammation of an intense character has a powerful tendency to prevent it from acting on the salivary glands. Be assured of this, that if, in any acute visceral inflammation, after you have performed the usual depletions, you find an unusual resistance to the action of mercury, you may, on that account, form a more unfavourable prognosis. There is one point in the treatment of dysentery which it is necessary you should be acquainted with. Sometimes the symp- toms steal on gradually, and the patient appears to be in a condi- tion not at all dangerous, when, all at once, the disease explodes with violence, and exhibits an extraordinary intensity ; the fever is ardent, the tormina excruciating, the tenesmus constant and harassing, the dejections frequent and blended with lymph and blood. Such an array of threatening symptoms must be met with a corresponding activity. In such a case as this I would bleed, leech, use the hip bath, and give free doses of calomel and opium; and if you were to ask me to which of the internal remedies used I should attribute the most decided alleviating influence, I should say to the opium. Dr. Cheyne says, “after"the lancet, the best remedy I know of is opium.” He says further: if another epidemic, similar to that which he witnessed, occurred, he would SPORADIC DYSENTERY. 93 have no hesitation in giving opium, in four-grain doses, in such cases. There was a very curious circumstance connected with the his- tory of the epidemic dysentery of 1818—19. At one time the deaths happened to be extremely numerous, and every thing which the experience or ingenuity of Dr. Cheyne could suggest failed in arresting the disease, in many cases. An English physician, who happened to be in Dublin at that period, and was in the habit of visiting the hospital, proposed the administration of large doses of cream of tartar, stating that he had tried it on several occasions under similar circumstances, and was convinced of its value. As the cases were not succeeding which had been treated after any of the ordinary modes, Dr. Cheyne consented to the exhibition of the cream of tartar, and allowed the physician to prescribe and ad- minister it himself. Accordingly, he proceeded to give it in doses of half an ounce every fourth hour. Its first effect, generally, was to produce violent distress, and to aggravate all the symptoms, but, after three or four doses, bilious and feculent stools came away, and the patient experienced the most extraordinary relief. Many cases which had been considered desperate improved and reco- vered, and Dr. Cheyne expresses his conviction that many persons were saved by this practice, who would have been lost under the ordinary modes of treatment. One of the old German authors has also alluded to this singular efficacy of cream of tartar in the treat- ment of dysentery ; and from the result of Dr. Cheyne’s experi- ments, there can be no doubt that it is entitled to a high rank among the remedies usually employed. In case you should prescribe castor oil as a laxative, it will be necessary to combine it with mucilage of gum arabic and a few drops of laudanum; given alone it will be likely to prove too irritating, particularly during the acute stage. In the advanced stage much benefit will be derived from a combination of castor oil with tincture of opium and a small quan- tity of oil of turpentine. This is not at variance with the pathology of the disease, for there is a period in this as well as in every other form of inflammation, when stimulants may be used with benefit. Such is the treatment of the ordinary forms of acute dysentery; but it may happen that you will be called to a case in which you cannot employ these decided measures ; and here I shall mention, that in all local inflammations it is of the utmost importance that you should act with judgment and decision in the commencement. Every hour is precious; a single day is worth much ; and if two or three days are allowed to pass, and the treatment is inactive or indecisive, the patient too often sinks into the chronic stage, or dies. Whenever you happen to be called to treat a case of acute local inflammation, attempt to cut it short as soon as possible; it is much easier to cure an inflammatory attack in its commencement than to save the patient from the effects of it in the advanced stage. Now, if you should be called to a case of dysentery of some stand- ing, and on your arrival find the patient lying on his back, his skin of a pale dirty hue, his eyes sunk and without lustre, his 94 STOKES’S THEORY AND PRACTICE OF MEDICINE. extremities cool, and bedewed with a clammy sweat; his pulse small, rapid, and feeble; his thirst ardent; his pains and tormina incessant; and constantly passing from his bowels a quantity of fluid matter, blended with depraved mucus, lymph, and blood, with great irritation about the anus, and if these symptoms have lasted for some days you may be sure there is extensive ulceration of the lining membrane of the large intestine. How are you to act under such circumstances ? The patient will not bear bleeding, or per- haps the application of a small number of leeches. Here your sole object must be to support your patient’s strength; you must give wine, (if the skin be cool,) strong chicken broth, beef tea, jellies, &c.; you must wrap your patient in flannel, and have recourse imme- diately to anodyne and astringent injections, and you should blister the abdomen, taking care to remove the blister at a proper time, and not leave it on so long as may add to the existing irritation. You may also prescribe the acetate of lead, or the sulphate of zinc with tincture of opium. I have seen several cases of this kind in the Meath Hospital, in which the administration of the sulphate of zinc was attended with good effects. The best mode of using it is to dissolve ten or twelve grains of the sulphate of zinc in six or eight ounces of cinnamon water, with a proportion of laudanum, and direct this quantity to be taken during the twenty-four hours. Dr. Elliotson recommends the sulphate of copper, and you can employ it in combination with opium. In this way, by supporting your patient’s strength, keeping him warm, paying attention to the state of his bowels, using counter-irritation, and prescribing astrin- gents combined with opiates, (taking care not to check the discharge too suddenly,) you will often succeed, even in very bad cases. Before I quit this subject I may observe, that Dr. O’Beirne has succeeded in some cases, and in others has given great relief by the use of tobacco injections. You can understand this when you reflect that tobacco acts powerfully on the general system, and pro- duces effects somewhat analogous to bleeding. Like general bleed- ing it brings on faintness, vomiting, cold skin, perspirations, and feeble pulse. It is also a powerful antispasmodic. and Dr. O’Bierne states, that its employment has been attended with the best effects in several very bad cases. I have not tried this remedy but I think it well worthy of a trial in the acute stage of dysentery, when there is room for an antiphlogistic treatment. In the ad- vanced stages, of course, it is inadmissible. We come now to consider the affection of the digestive tube, which merits a separate consideration, and this is tympanitis, or, as it is sometimes termed, meteorism. I shall not enter upon the ge- neral pathology of aeriform effusions into the abdomen ; we are not acquainted with that peculiar condition of parts which produces them, but it is now established that we may have effusions of air, not only into the digestive tube, but also into every part of the body. The term tympanitis is limited to effusion of air into the digestive tube, in all parts of which we may find it. We detect it in the stomach under two circumstances; first, as a recent and SPORADIC DYSENTERY. 95 transient affection, as when it comes on after swallowing indigesti- ble matter; secondly, in a more permanent form, as when it depends upon hysteria, hypochondriasis, or chronic gastritis. It may be also frequently seen in very young children, when there is fever- ishness with irritation of the digestive system. I recollect a very remarkable case of this kind, in which the distension was so great, and the pressure on the diaphragm so considerable, as to cause displacement of the heart upwards ;—this, I believe, has not been mentioned among the causes of displacement of the heart. The symptoms of this affection are sufficiently obvious;—a sense of uneasiness and distension at the region of the stomach ; when the effusion is in excess, a distinct tumour can be felt, and the sound on percussion, over the stomach, is like that of a drum. It often happens, also, that when the patient is shaken, a distinct sound of fluctuation is heard, a circumstance which more than once has led to the suspicion of the existence of pneumothorax, or empyema. There are also cases on record, in which the distension was so great as to cause rupture of the stomach, and effVision of its contents into the cavity of the peritoneum, causing intense inflammation and rapid death. The effusion of air into the intestinal tube is extremely common in cases of acute enteric inflammation and gastro-enteritis, after the disease has lasted for a few days, and, as this is a matter of consi- derable interest, I wish to make a few remarks upon it. It is of importance that you should bear in mind that this is one of the results of enteric inflammation, because many persons are in the habit of looking upon it, not as a mere symptom of another affection, but as a peculiar form of disease, forgetting that it may occur with, as well as without, inflammation. In consequence of this limited and imperfect view of the subject, they are in the habit of prescribing turpentine as a specific remedy for tympanitis. Now, I can say that I have seen the most dreadful effects from the administra- tion of turpentine in the tympanitis of acute enteric inflammation. The immediate effect is to produce a rapid dimunition of the tym- panitic swelling ; but this is purchased at too dear a rate ; for you will find next day that there will be a violent exacerbation of the existing symptoms, and the tympanitis becomes worse than before. You should never, therefore, interfere in this way with the tym- panitis of acute enteric inflammation, nor should you alter your practice on this account in the slightest degree, except where the tympanitis is so great as to interfere with the due performance of the function of respiration; but, in the advanced stage, after the twelfth or sixteen day, when the fever has abated and the tongue is moist, I have frequently seen great advantage result from the use of turpentine. But as long as the condition of your 'patient admits of antiphlogistic treatment, be assured that the administration of turpentine is hazardous. When the patient is in a low state, when you can no longer have recourse to bleeding or leeching, when the tympanitis is connected with an asthenic condition of the intestinal mucous membrane, then, and not till then, should you venture on 96 STOKES’S THEORY AND PRACTICE OF MEDICINE. the employment of turpentine. I shall return to this subject when we come to speak of hysteria. I may mention here, that the occurrence of flatus in the intestines sometimes gives rise to dreadful sufferings in that affection which has been termed windy colic. A person in the enjoyment of good health happens to take at his dinner or supper a quantity of indi- gestible food, he goes to bed without feeling any particular inconve- nience, but about the middle of the night he awakes with an attack of pain and tormina, which extend from the hypochondria to the umbilicus. This subsides for a short time, and then returns with violence, and the patient often finds that it is relieved by pressure. In a short time the pains get worse, and the abdomen begins to swell, sometimes at one point, sometimes at another, as if the air was confined and pent up in particular situations. The patient begins to suffer indescribable anguish, he has great anxiety, extreme prostration of strength, his face is pale, his extremities cold, a cold sweat breaks out all over the body, and he sits bent forwards, with his hands pressed on his stomach to relieve the paroxysms of pain which come on with increasing rapidity. In some cases there is distressing hiccup, in some a large quantity of aqueous urine is passed, in some there are loud borborygmi, and the intestines may become so enormously distended as to fall rapidly into a state of gangrene. Hippocrates has given a description of one of the forms of this disease, which terminates by the passage of air upwards and downwards, by which the patient obtains relief; this he calls dry cholera. This windy colic is an exceedingly violent disease: one of the first cases of it which I witnessed, presented such an array of alarming symptoms, that I thought every moment the patient would expire. It is, however, a disease which is generally easily managed if taken in time. One of the first things to be done is to apply heat to the abdomen by anodyne stupes, or warm flannel. Flannels wrung out of a decoction of popyheads, as hot as can be borne, will do a great deal of service, and in some cases will give complete relief, when assisted by the use of carminative draughts. But of all the remedies which I have seen, the most efficacious is an injection with tincture of asafoetida, turpentine, and opium. This is gene- rally followed by speedy relief, the pulse becomes more natural, the belly soft, and the excruciating agony is relieved. This is the mode of treatment in which I have the greatest confidence. After the acute symptoms are removed, it will be proper to exhibit a laxative, for the purpose of removing the exciting cause of the disease—indigestible matter; unless you get rid of this, your patient is liable to a return of the attack, and even to an inflammation of the tube itself. Be not, therefore, satisfied with merely relieving your patient; watch him carefully, and, by a proper treatment, obviate a recurrence of the symptoms, and prevent any tendency to inflammation.1 1 When the flatus is pent up in the large intestine, as it often is, (the very term colic, indeed, indicates the common belief of old, that the colon is its ordinary seat,) instantaneous relief is often afforded by passing up a hollow PATHOLOGY OF JAUNDICE. 97 LECTURE XII. Pathology of jaundice—Its co-existence with a flow of bile—Case of aneurism of the hepatic artery—The disease, independent of mechanical construction—Colouring of the various parts—Effects on the milk, and humours of the eye—Jaundice with pre- servation of health—Icterus infantum. To-day we have to enter upon the consideration of a subject, the nature and extent of which claims for it a more than ordinary share of importance—I allude to that form of disease which is termed jaundice. I have selected this disease for our present lecture, be- cause I think we may look upon it as presenting a series of pheno- mena, which form a distinct link of connection between affections of the liver and the digestive tube. In the first place, jaundice, and I wish to impress this upon your attention, is to be regarded as a symptom rather than a disease sui generis, and that it is a symptom which occurs in many diseases of a most essentially opposite pa- thological character. There is nothing, for instance, more different than disease accompanied by acute inflammatory action, and disease without any inflammation at all; yet we may have perfect jaundice as a consequence of the one as well as the other. No diversity can be more complete than that which exists between the jaundice arising from inflammation and organic lesion of the liver, and that which results from simple mechanical obstruction of the biliary ducts. It is, therefore, to be looked upon not as a disease but as a symptom, and we may define it by saying, that it is a state in which the solids and fluids of the body are tinged more or less deeply with bile. Generally speaking, this presence of bile in fluids and solids where it should not be normally, is accompanied by the absence of that secretion in the place where it is naturally found, the digestive tube. Yet it is an interesting physiological fact, and one of practical importance, also, that we may have plenty of bile in the stools during an attack of jaundice, or that we may have jaundice co-existing with even a copious flow of bile. This is a strong proof in favour of the opinion, that some cases of jaun- dice have no connection or dependence on the absorption of bile into the system, as, in the instances to which I have alluded, there is no mechanical retention of bile; the biliary ducts and gall-bladder are open, the bile passes freely into the intestines, and yet the whole body is jaundiced. I have told you that jaundice is a symptom which is produced by a variety of causes—these I shall briefly enumerate. Without en- tering into the ultimate mode of action of these causes, and their bougie through the annulus of the rectum into the colon. The editor had the satisfaction of preserving the valuable life of an aged individual, who had been long honourably engaged in the service of his country, by this simple expedient. Injection after injection had been employed ineffectually. An elastic gum male catheter was passed up, the flatus was immediately discharged, and the pain and tympanitic distension were at once removed. R, D. 98 STOKES’S THEORY AND PRACTICE OF MEDICINE. separate effects on the economy, it will be sufficient for my purpose to mention them individually. The first of these causes I take to be mechanical obstruction to the exit of the biliary secretion. Under such circumstances one of these two things is supposed to take place, either that the bile, which is poured into the biliary duct and gall-bladder, and cannot get into the duodenum, is re- absorbed, or, according to another opinion, that the innervation of the liver is injured; in other words, that the liver is paralysed and unable to perform its ordinary functions, and that, consequently, it does not separate the materials of bile from the blood. The latter opinion has been advanced by men of high authority in the medical world, but when we find, on dissection, (as is not unfrequently the case in jaundice,) the biliary ducts and gall-bladder distended with bile, we cannot infer a paralysis of the liver as the cause of the disease, we must attribute it to the re-absorption of bile. I have taken mechanical obstruction to the flow of bile as one of the causes of jaundice. Now, you will find this to depend, in the first place, upon the presence of gall stones in the biliary or common ducts. A biliary calculus is formed in one of these ducts, it excites violent irritation, spasmodic pain, and often (but not always) jaundice. At my next lecture I will show some specimens of this obstruction. In the second place, the biliary ducts may, from various causes, become obliterated ; they may be closed by adhesion, as the conse- quence of inflammation, or they may be impervious as the result of congenital malformation. In some cases children have been born without biliary ducts, in others the ducts have terminated in a mil de sac. A third cause of jaundice by mechanical obstruction is, where the flow of bile has been prevented by the pressure of tumours on the biliary ducts. Of this one of the most familiar instances is disease of the head of the pancreas, or malignant disease of the pylorus or duodenum. I have on a former occasion alluded to a case of jaundice produced by aneurism of the hepatic artery, one of the rarest pathological circumstances on record, and one which has not been hitherto described. So rare is it, that at a late meeting of the Academie de Medicine, that eminent pathologist, Cruveilhier, stated that he had never, seen a case of it. I was so fortunate as to meet with an instance of this uncommon form of disease, and will take an early opportunity of exhibiting the prepa- ration of it to the class. You will see by it how an aneurism of the hepatic artery may cause a complete obstruction to the flow of bile, and I shall be able to show you, that not only the trunks, but also the minute ramifications of the biliary ducts, are enormously dilated and filled with retained bile, and that these dilatations are continued up to the peritoneal surface of the liver, forming as it were so many aneurisms by dilatation of the biliary ducts themselves. The last cause of jaundice from mechanical obstruction, is that which de- pends upon the accumulation of scybalous matter in the bowels, a thing frequently met with in old persons. Dr. Marsh alludes to this form of the disease in his admirable paper on jaundice in the Dublin Hospital Reports, and brings forward cases in which the 99 PATHOLOGY OF JAUNDICE. jaundice disappeared rapidly under treatment calculated to remove accumulations of hard faecal matter from the intestines. So much for the varieties of jaundice which depend upon mechanical ob- struction. Before I quit this part of the subject it will be necessary to allude to another form of the disease, which bears some analogy to those already mentioned, namely, the spasmodic jaundice. With respect to this variety there exists a great deal of doubt; some per- sons maintain that the ducts are muscular, and consequently liable to spasm like all other parts of the muscular system; others deny the existence of muscular fibres in the ducts; while a third party are of opinion that the spasm resides in the duodenum, and that the contraction of its muscular fibres is the sole obstacle to the free passage of bile. It is of very little consequence which of these opinions we adopt; the fact is, that this is a form of the disease which we occasionally meet with in persons of an hysterical or hypochondriac habit, but what is its exact seat we cannot ascertain. The probability is, that it is spasm of the duodenum itself. The next class of causes giving rise to jaundice, are those which are connected with acute or chronic disease of the liver, as, for instance, the different varieties of hepatitis and the existence of mor- bid growths in the substance of the liver. Here, however, it must be recollected that the occurrence of hepatic disease in the acute or chronic form does not necessarily imply the existence of jaundice ; in other words, there are some cases of disease of the liver in which bile is freely discharged into the digestive tube, others in which it is not, so that the non-secretion of bile and the consequent produc- tion of jaundice are to be looked upon as accidental complications. I have seen a case in which there was enormous destruction of the liver from suppuration, where one of the lobes was almost entirely converted into a bag of purulent matter, and the other extensively diseased, yet the patient had not the slightest tinge of jaundice. We are ignorant, therefore, of the cause which determines the production of jaundice in one case of hepatic disease, and not in another; the question remains to be decided by future investiga- tions. All we know is this, that it may occur or be absent in every form of acute or chronic disease of the liver. The third great source of this affection is disease of the mucous surface of the stomach and duodenum, the most important, because it is the most frequent, cause of jaundice. We are indebted to the researches of modern pathology for a correct notion of this form of the disease, and for the invaluable light thrown upon its treatment, which, up to the time of Broussais, had been extremely confused and empirical. Inflammation of the upper part of the digestive tube is an extremely frequent cause of jaundice, and this result is, generally speaking, independent of any mechanical obstruction of the gall-bladder or biliary ducts. This phenomenon may be explained by calling to mind the various examples of sympathetic irritation, and by recollecting that disease in one situation frequently produces disease in another, or, in other words, that we have an irritation of the stomach and duodenum, in which the liver sympa- 100 STOKES’S THEORY AND PRACTICE OF MEDICINE. thetically partakes, and, as a consequence of this, the biliary secre- tion is arrested. In a former lecture, I alluded to the strong sym- pathy which is known to exist between mucous membranes and the glands whose ducts open upon their surfaces. It is supposed by some that the irritation existing in the duodenum may be ex- tended to the liver, producing paralysis of the functions of that organ and jaundice. It would appear, also, that the yellow fever of warm climates is only a variety of jaundice depending upon irritation of the gastro-intestinal surface. On this point the best pathologists seem to have made up their minds. The last cause of jaundice seems to consist of the sympathetic action of the brain upon the liver, and this is an extremely curious circumstance. There are numerous cases on record of persons who have received an injury of the brain becoming jaundiced, and the same affection has been repeatedly known to supervene on pow- erful mental emotion. Thus we find that Murat, on learning that his queen had assumed the sovereign power of Naples in his absence, fell into a violent passion, and became almost immediately jaundiced. The close connection which exists between the brain and the biliary system has been long known; it is unnecessary, therefore, that I should enter upon its consideration, for the purpose of accounting for an occurrence the nature of which must be ob- vious to all. You will, however, find that jaundice is, in the majority of cases, connected with disease of the gastro-intestinal surface, and that this is one of the most common causes of the sporadic jaundice of this country. I shall return to this subject on a future occasion, when we enter upon the consideration of hys- teria. Before I enter upon a description of the separate forms of jaun- dice, it will not be amiss to premise a few general remarks. I told you, at the commencement of my lecture, that we define jaundice by saying, it was that state in which the solids and fluids of the body were tinged more or less deeply with bile. Now, is this definition to be received without any exception ? and does it em- brace all the solids and all the fluids of the body? I have stated, that in some cases you will not be able to detect the slightest trace of bile in the stools. This is, hoAvever, but an apparent exception; it is, perhaps, because the bile is too small in quantity to be able to overcome the diluting power of the ingesta, or that the portion of it which finds its way into the digestive tube is too small to be appre- ciable by our senses under these circumstances. The rule of uni- versal colouring in this disease will not, I believe, hold good, at least there are certain fluids and solids which are tinged only in a very slight degree ; but the majority of the textures and fluids have been observed to be more or less distinctly coloured. For instance, we find the jaundiced tint appearing in bone, cartilage, muscle, in the cellular membrane, in the centraf portions of the teeth, but not in their enamel. It is doubted whether the hair is coloured or not, but it is the opinion of many that it is, and a professional friend of mine has assured me that he has had unquestionable proofs of the PATHOLOGY OF JAUNDICE. 101 colouring of the hair. The membranes of the brain are distinctly- tinged. I have seen the arachnoid and pia mater decidedly coloured in a case of dreadful gastro-duodenitis, to which I shall call your attention on a future occasion. The substance of the brain, how- ever, has not been found to partake in this universal discoloration. Frank, who is a good authority on this point, states that the sub- stance of the brain is never coloured, though the membranes may, and most commonly are. In my experience of jaundice, I have found the membrane distinctly coloured, but never could see any tinge of yellowness in the substance of the brain. I have how- ever observed, that when a horizontal section of the brain had been made in such cases, the orifices of the divided vessels, which are denoted by bloody points in the healthy state, seem to pour out a quantity of yellowish blood, but the substance of the brain appeared white and normal. With respect to the state of the fluids, you will find the blood distinctly coloured; the saliva also is yellow; the urine is loaded with bile, it stains the linen, and chemical analysis shows that a large proportion of the biliary secretions is blended with it. The perspiration is also tinged with it; and if you apply a blister you find the exuded serum bilious. If a person, labouring under phthisis or bronchitis, should happen to get an attack of jaundice, the pul- monary secretions will be often tinged with yellow. The mucous secretions from the vagina and uterus are also discoloured; but it is an interesting and curious fact, that the milk during lactation seems to escape the general impregnation with bile, and is never tinged. This would appear to be a beautiful provision of nature to prevent the child from being injured. Frank, who witnessed two epidemics of jaundice, one at Mayence, in 1754, and another at Ghent, 1742, states that he has never seen the milk tinged with bile. Dr. Marsh, in his paper on jaundice, mentions that in the case of one unfortunate female a yellow fluid was squeezed from the breasts after death ; but this cannot be considered as a proof of the existence of bile in the milk duringf life. In jaundice the eye almost always presents a very distinct yellow tinge, and yet it is a curious and interesting fact, that the patients very seldom complain of yellow vision. Out of several thousand cases of jaundice, Frank only met with five in which this symptom was observed. The occasional occurrence, however, of yellow vision in jaundice, has excited a good deal of interest; and Drs. Graves and Elliotson, who have turned their attention to this sub- ject, have made some ingenious and valuable remarks on this sin- gular phenomenon. Dr. Elliotson’s opinion is, that where this symptom is complained of, the cornea is in a state of irritation or inflammation, and that under these circumstances its vessels, which in their physiological condition are too small to allow of the passage of coloured fluids, become dilated, so as to carry bilious blood across the field of vision, and thus cause all objects to wear a yellow hue. To support this opinion, he brings forward the case of a jaundiced patient, who had a considerable degree of inflammation in one eye 102 STOKES’S THEORY AND PRACTICE OF MEDICINE. but none at all in the other, and who saw objects yellow .with the inflamed eye, but of their natural colour with that which was free from inflammation. This case is, indeed, as far as it goes, extremely interesting; but I think it does not prove the point in question, namely, that the cause of jaundiced vision is irritation of the cornea, for it is a fact that even when the cornea is deeply tinged, yellow vision is not of constant occurrence, nor does it affect all persons alike. One person sees objects in their natural colours ; to another under the same circumstances every object appears to wear a yellow hue, and what is equally remarkable, this yellowness of vision is fre- quently intermittent; it is present to-day and disappears to-morrow. These are extremely curious facts. The object of Dr. Graves on this subject, in the Dublin Medical Journal, is to explain the cause of the absence of yellow vision in certain cases of jaundice. He believes that the humours of the eye frequently escape the jaundiced tinge, and suggests that this may be a beautiful provision of nature for the preservation of sight. From his own observations he states that the aqueous, and perhaps the vitreous, humours escape. But, it may be objected to this, that when all the fluids, the blood, saliva, serum, perspiration, &c., are impregnated with bile, how is it possible that the fluids of the eye should escape?—Does it not seem very extraordinary?—It does, certainly; but that it is possible seems to be established by the fol- lowing circumstances;—you are not to conclude, because all the fluids which are found to exist in the blood are filled with bile, that the secretions, properly so called, which do not exist in the blood, should be also tinged with bilious discoloration. This is the an- swer which Dr. Graves makes to this objection—I recollect two cases of malignant cancerous disease of the liver, which were some time ago in the Meath Hospital, and which presented symptoms of universal jaundice before death. In these cases we found fluids deeply impregnated with bile—every thing, in fact, seemed bilious and discoloured; and yet, you will hardly credit me when I tell you, that, on opening the gall-bladder, it was found to contain a quantity of beautiful limpid fluid, perfectly transparent, and of a high refractive power. Here, then, is a fact to prove that we may have intense general jaundice, and yet find in a sac, existing in a system so diseased, a quantity of fluid perfectly free from any bilious admixture, proving, at least, that it is possible that the humours of the eye may in a similar manner escape. Dr. Graves further remarks, that, even where the humours of the eye happen to be- come tinged, the alteration in the colour of objects may still escape the observation of the patient; because the change takes place gra- dually and insensibly. The patient does not think every thing he sees is yellow; he believes still that they are white, because the transition from one colour to the other has been so insensible as to escape his notice. This reasoning may, I think, apply to cases of yellow vision coming on gradually, but will not explain those in which it has been of sudden occurrence. The other cause which Dr. Graves adduces as tending to prevent a patient with a yellow PATHOLOGY OF JAUNDICE. 103 cornea from seeing objects of the same colour, is, the want of some standard of comparison to judge by. He has no means of compar- ing objects; and, though he sees this piece of paper, for instance, (yellow,) he thinks it white, because every standard he looks to, every other piece of paper he examines, presents the same tinge, Dr. Johnson states, that most of the jaundiced patients whom he has interrogated were sensible of the alteration in vision to a greater or less degree, and observes that the power of appreciating varieties of colour is retained, though we look through a yellow medium not deeply dyed, though yellow, of course, is made to enter into this composition. You will see this observation in the Medical Chirur- gical Review for October, 1833. I shall conclude this subject with an observation which suggests itself to me, and this is, that the alteration of colour and vision may arise from other causes than the mere jaundiced condition of the eye; and that it may (I believe this has not been taken notice of before) depend upon direct nervous influence. There are cases on record of patients labouring under typhus fever, who, without being in the slightest degree jaundiced, saw every thing yellow. There are also numerous instances of various colours, differing from the natural hues of the objects, being seen by patients in con- sequence of affections of the nervous system; and hence it is ex- tremely probable that many cases of yellow vision in jaundice may depend upon a functional lesion of the optic nerves. I have one fact to bring forward on this subject of great importance. In the case of jaundice from aneurism of the hepatic artery, the patient saw every thing intensely yellow, until a few days before death, when all yellow vision subsided, and he saw objects of their natural colour, though the jaundice continued, if possible, more intense than ever. In this case there was no inflammation of the eye. I do not think that Dr. Elliotson’s observations apply to all cases of this phenomenon. All that he has said is, that where the cornea is in a state of inflammation, there is a greater probability that there will be yellow vision in the affected eye or eyes; and this can be easily accounted for by the increased size of the vessels which the inflammatory process brings on. We may however conclude, that, in some cases, the alteration of vision may be owing to a yellow state of the humours of the eye, that in some it is the result of in- flammation, and that in some it may be fairly attributed to a lesion of innervation. I think that the latter statement is borne out by the facts that there is a want of constancy in the occurrence of this phenomenon, that it is often of a more or less intermittent character, being one day present and another day absent, and that it has been observed in cases where not the slightest symptom of jaundice ex- isted. We must also bear in mind that some of the most remark- able nervous systems commonly occur in jaundice, such as coma, &c.; and we may enquire how far the occurrence of yellow vision may be looked on as an indication of an excited state of the brain, and so lead us to measures calculated to remove impending danger. 104 STOKES’S THEORY AND PRACTICE OF MEDICINE. Let us now return to the more immediate consideration of jaun- dice. One of the first diseases of children is the icterus infantumi, or, as it has been termed by nurses, the yellow gum. Children, shortly after birth, without any known cause, become suddenly jaundiced, and this, after continuing for some days, goes off, fre- quently without any treatment. This form of jaundice appears to depend upon some particular irritation of the intestinal canal, which seems to result from the circumstance of the digestive system being called into active exertion for the first time, and receiving a new stimulus from the mother’s milk. It is a curious fact, that this form of jaundice generally disappears spontaneously. Now, it is remark- able, in this as well as other cases, (when we recollect the nature of jaundice, and that there exists in the fluids of the body an irritating substance like bile,) that the effects of an admixture of the biliary- secretion with those fluids should not be attended with more striking symptoms. In some instances we shall have intense jaundice without any particular effect upon the economy. There is some itching of skin, ardour urinae, a little depression of spirits, and vertigo, which last for a few days and then disappear. Dr. Gre- gory mentions many cases of persons affected with jaundice who went about their ordinary business, and performed all the functions as if in a state of perfect health, eating, drinking, and sleeping in their usual manner. I have myself seen persons who laboured under this affection for more than a year, and yet had all that time their digestion good, their bowels regular, the flow of urine natural, and the circulatory, nervous, and respiratory systems apparently conformable to the standard of health. Dr. Blundell gives the cases of two children who lived for four months, apparently well fed and healthy; and, on opening their bodies, it was found that the biliary ducts terminated in a cul de sac, and that, consequently, not a drop of bile had been discharged into the intestines. Sir Everard Home gives a remarkable case of the total absence of the gall-bladder, and no passage of bile into the intestines, occurring in connection with a perfect state of health. These are curious facts, and should be borne in memory. I remember two cases of pro- tracted jaundice in the persons of two male servants, who were admitted into the Meath Hospital with symptoms of irritation in the upper part of the digestive tube. From this both recovered under an appropriate treatment, but the jaundice continued in one for eighteen, and in the other for sixteen months. One of them, a stout, well-built, and fully developed man, came into the hospital some time afterwards in the apparent enjoyment of perfect health, except that he had still the jaundiced colour. He wished to be taken into the hospital to get cured of his jaundice, stating that, in consequence of the peculiarity of his appearance, he could not get a place any where, and was in a very distressed condition. From these facts it seems fair to conclude that the symptoms of other affections, occurring after jaundice, are owing to some other cause than the bilious state of the blood. I find that my time is nearly expired; I cannot, therefore, enter JAUNDICE FROM GASTRO-DUODENITIS. 105 into the various causes of jaundice to-day; at our next meeting I hope I shall be able to conclude this subject, and then pass on to the consideration of hepatic disease. LECTURE XIII. Jaundice from gastro-duodenitis—Researches of Broussais and Marsh on—Jaundice without hepatic inflammation—Nervous symptoms—Treatment—Yellow fever—Its occurrence in this country—Predominance of gastric irritation in warm climates— Typhus icterodes—Jaundice from biliary calculi—Different situations in which biliar}7 calculi may be found. We commence to-day with the consideration of that form of jaun- dice, which, taking all its cases into account, appears to be the most common. The pathological expression for this form of the disease is, that it is inflammation of the upper portion of the digestive tube, or, in other words, that it is the result of a gastro-duodenitis. In this case, an inflammatory affection of the stomach and duodenum acts sympathetically on the liver, and we have jaundice occurring independent of hepatic inflammation or mechanical obstruction to the flow of bile. This variety of the disease it is important you should be accurately acquainted with, as it is not only exceeding common in temperate climates, but because I believe it is a great cause of mortality in warm countries, and that the yellow fever of the tropics is reducible, in a great measure, to this form of disease. In other words, that the cause of the yellowness, and many other of the symptoms, is to be referred to an intense irritation or inflam- mation of the digestive tube, with a predominance of that irritation in its upper portion. The jaundice which depends upon gastro-duodenal inflammation, was first accurately described by Broussais. Dr. Marsh has also made many valuable additions to our knowledge on this subject, in his paper on jaundice, published in the fifth volume of the Dublin Hospital Reports. You will find, too, that in a case of jaundice described by John Hunter, he suggests the possibility of its being preceded by inflammation of the duodenum. But I believe we are chiefly indebted to Broussais for our first correct notions of the pathology of this disease, and for its scientific and successful treat- ment. The disease may occur in the acute form, or it may come on in a slow insidious manner; but in either case, as far as my expe- rience goes, it is always accompanied by symptoms referable to a morbid state of the mucous membrane of the intestines. Dyspeptics, and individuals subject to diarrhoea, are liable to it; but it may also attack strong and healthy persons from the two following causes. A man is exposed to considerable heat, his body is bathed in perspiration, he experiences some degree of lassitude, and is very thirsty; in this state he takes a large draught of cold water. In a 106 STOKES’S THEORY AND PRACTICE OF MEDICINE. few hours afterwards he begins to feel uneasy, and complains of being unwell; he gets shivering, nausea, thirst, and fever, and this fever and thirst, with bilious symptoms (as they are called), con- tinue for two or three days, when some morning, on awaking, the patient finds himself jaundiced. The same thing may happen as a consequence of error in diet. A person eats at supper a quantity of indigestible food, next day he has vomiting and thirst, and in a day or two more jaundice appears. I may remark here, that this indis- position of two or three days’ standing is a very curious and interest- ing feature in the disease, and would seem to be connected with the progress of disease in the mucous surface of the stomach and duodenum. Jaundice from gastro-duodenitis generally occurs in this country under two varieties. The first is an extremely mild disease; it comes on with very slight and transient symptoms of constitutional or local derangement; it seldom prevents the patient from pursuing his ordinary avocations, and generally disappears without any trouble. The second variety is an extremely severe and frequently a fatal disease; between this and the former there are numberless shades and gradations. Let us take a case of the more severe form of jaundice. The cause of this, as I have already mentioned, is often the taking a copious draught of cold water while the body is heated by exercise, or eating a quantity of indigestible food. The patient is indisposed for two or three days before the jaundice appears ; he lias nausea, vomiting, great thirst, loss of appetite; he complains of burning heat in the epigastrium, and there is some tenderness on pressure over the region of the stomach and duodenum. His tongue is foul, his bowels costive, his urine loaded; he has considerable prostration of strength, complains of vertigo and lowness of spirits, and is con- stantly sighing. There is always more or less febrile disturbance; in some cases the fever is ephemeral, and goes off in a day or two; in others it continues for a much longer period. When this fever continues beyond the second or third day, it is to be looked upon as an unfavourable sign, and you may expect that the case will be unmanageable and dangerous. There is another remarkable symp- tom on which I have had reason generally to found an unfavour- able prognosis, and this is a variation in the intensity of the yellowness. In some cases, you will find that to-day the counte- nance and skin are much less yellow, and this is always noticed by the patient, whose spirits are generally raised by the decline of the jaundiced tint, but in a day or two it becomes as deep as ever, and it may go on in this way, alternating from a faint to a deep tinge, and vice versa. This is an unfavourable symptom; it appears to indicate the repetition of inflammatory action in the intestinal tube, because each increase in the depth of the yellow tinge is accom- panied by an increase of the epigastric symptoms. In such cases as this, the patient does not, as under other circumstances, shake off the disease and return to his usual habits; he lies in bed, and though he complains of no pain, except when you make firm pres- sure on the epigastrium, still he is not at all improving; he tells JAUNDICE FROM GASTRO-DUODENITIS. 107 you he is better, but he is still languid, and his appetite does not return. The stools are generally clay-coloured, but this is not a necessary consequence of jaundice ; they are sometimes yellow, and 1 have seen them of a perfectly healthy appearance. The pulse, in most cases where the fever is ephemeral, returns in a few days to its natural standard ; in some instances it is remarkably slow, and this state of pulse is to be regarded as an unfavourable symptom. Sometimes there is a slight degree of subsultus tendinum and delirium ; and I must observe that you are never to forget that the early supervention of nervous symptoms, in any form of this dis- ease, is always to be looked upon with suspicion. One of the most alarming complications, however, of this gastro-duodenal jaundice, is the occurrence of coma during its progress, a symptom to which the attention of the profession was tirst strongly directed by Dr. Marsh. He has given several cases of jaundice, characterised by this symptom, the majority of which resisted all the ordinary resources of medicine, and terminated fatally. I must confess, too, that I have never seen a case, in which the coma was distinctly established, terminate favourably. You should, therefore, when called to treat a case of jaundice, be always on the alert, and never allow any bad symptom like this to steal upon you ; and it is gratifying to think, that if you take this symptom in time, you will, in all probability, be able to overcome it. An extremely interesting paper on this coma, occurring in jaun- dice, will appear in the forthcoming number of the Dublin Medical and Chemical Journal, from the pen of Dr. Griffin, of Limerick. He gives the details of some extraordinary cases, which you will find well worthy of an attentive perusal. Out of four cases in one family, which he attended, two died, who had become comatose at an early period: in the other two, the affection of the brain was relieved by bleeding and other active measures. From this it would appear, that the mere supervention of coma is not necessarily followed by death, but that it is an exceedingly dangerous symptom when it comes on at an early period of the disease. It is very diffi- cult to give a satisfactory explanation of this. Some persons think that it is attributable to the action of the bile on the blood which is circulating in the brain. This explanation would answer very well if coma was a symptom of common occurrence; this, however, is not the case, and we must seek for some better reason. It is stated, by some, that coma may be one of the consequences of the close sympathy which exists between the brain and liver. Dr. Griffin draws an analogy between the effects of suppression of bile in jaun- dice and suppression of urine in diseases of the kidneys, and thinks that the affection of the brain is of common occurrence in one as well as in the other. This analogy, however, is incomplete, for we have no case of complete suppression of urine without fever and other violent symptoms, but we have many cases of complete sup- pression of bile with very slight and almost inappreciable disturb- ance of the economy. It is very difficult, in the present state of medical science, to explain the coma of jaundice; all we know is, 25* 108 STOKES’S THEORY AND PRACTICE OF MEDICINE. that it sometimes occurs, that it is a bad symptom, and must be met with great activity. I may mention one fact which seems to be strongly opposed to the analogy of Dr. Griffin. It will be proper to observe here, that Dr. Griffin does not advance this as an opinion, or advocate it as a theory; he merely offers it as a hint or sugges- tion, leaving it to others to decide the question. We are not, there- fore, in examining this analogy, reasoning against any opinion of his. But with respect to this matter, the fact to which I allude is this—one of the worst cases of coma I ever witnessed, occurred in a patient who had no suppression or retention of bile; the bile flowed freely into the intestines, the dejections were distinctly tinged with it, and yet this man had deep jaundice and intense coma. We are still in want of a number of facts on this point; it is a subject which affords a large field for interesting enquiry, and Dr. Griffin deserves great credit for the philosophical and impartial manner in which he has brought his cases before the medical public. When a patient dies of jaundice, accompanied by this comatose affection, you are naturally anxious to ascertain the cause of death. INow what you will generally find is this: on opening the head you examine the brain accurately, but cannot detect any lesion of its substance or membranes; you then go to the stomach, and discover there marks of vascularity; you open the duodenum, and find it in a state of intense inflammation. I have seen many cases of this disease in which the mucous membrane of the duodenum was highly engorged and almost black. It is said that this inflamma- tion extends from the duodenum along the common biliary duct to the liver. I am not possessed of facts to confirm this assertion, but I have little doubt that, in the majority of cases, the jaundice is more the result of a mere lesion of innervation of the liver, than proceed- ing from any spread of inflammation along the ducts into its sub- stance. Unless we can demonstrate this inflammation, it is idle to assume its occurrence. When you examine the liver, gall-bladder, and biliary ducts, you generally find them in the normal state. In a few cases, the ducts have been found impervious from adhesive mucus; you will see in John Hunter’s works a case of this kind, which occurred in a consumptive patient. You will find a great number of important facts, relating to the pathology of jaundice, in the commentaries upon his own pathological propositions by M. Broussais. I would also advise you to peruse Dr. Marsh’s excellent paper in the Dublin Hospital Reports. We come now to the diagnosis of jaundice depending upon gastro-duodenal inflammation. In the first place, we learn from the history of the case that the exciting cause has been some excitant of inflammation in the mucous surface, the ingestion of indigestible aliment, or taking cold water into the stomach while the body has been overheated. The next thing is the supervention of fever with gastric symptoms, and these being followed, in two or three days, by an attack of jaundice, without any of the ordinary signs of hepatitis. Here we have a disease excited by taking cold water while the body is heated, or by indigestible food, preceded by febrile JAUNDICE FROM GASTRO-DUODENITIS. 109 disturbance with gastric symptoms, and unaccompanied by the symptoms or signs of hepatitis. When this combination of circum- stances occurs, you make your diagnosis with great certainty, and set it down as jaundice depending on inflammation of the stomach and duodenum, and treat it accordingly. There are but two forms of jaundice accompanied by symptomatic fever; the one under con- sideration, and that which is the consequence of hepatic inflamma- tion, or other disease. It might be supposed that the tenderness of the epigastrium was caused by an affection of the liver, but by making an accurate examination you will be generally able to dis- criminate with certainty. You will find that the pain is less than that of acute hepatitis, that strong pressure gives pain, not in the region of the liver, but in that of the duodenum; you can ascertain by a manual examination, and by the pleximeter, that there is no enlargement of the liver, that there is no remarkable dulness on percussion at the lower part of the chest on the right side, and when the fever is ephemeral, this will furnish you with much valuable assistance towards forming a correct diagnosis. With respect to the treatment of this form of jaundice, in mild cases, where there is little or no fever (for fever is to be taken as a test of the severity of the disease), the patient very often gets well without any treatment, and the jaundice, after lasting a few days or weeks, goes off spontaneously. In all such cases, a regulation of diet, keeping the bowels open by mild laxatives, and prohibiting wine, spirits, and other stimulants, will be found, in general, suffi- cient to remove all the symptoms. I wish, however, to impress upon you that it is of the utmost importance to cut short this dis- ease as soon as possible. There is no use in letting it get ahead of you ; and in every case where the symptoms are in any degree acute, and there is a degree of fulness and tenderness over the epigastrium, you will be culpable, if you omit to apply leeches over the stomach and duodenum, and prescribe iced water, and every other means calculated to remove inflammation. If you allow it to go on to a certain length, if you allow fever to progress, and coma to supervene, you will not be able to manage the case so easily. Never, then, omit the application of leeches the moment you have ascertained the existence of decided inflammation. Keep your patient’s bowels open by enemata, or by mild saline laxatives, regu- late his diet carefully, prohibit all stimulants, and he will generally do well. Many persons are in the habit of prescribing mercury in this dis- ease. From my own experience I cannot say whether this is right or wrong; but I can state that I have seen a great many cases get well without it. But in cases where the symptoms are obstinate, and the stools continue white, I think you would be justified in giving mercury, even so far as to produce salivation. I must remark to you, however, that I have seen two cases in which it was found impossible to produce the free action of mercury in patients labouring under this disease. The exhibition of small doses of cream of tartar, two or three times a day, made into an 110 STOKES’S THEORY AND PRACTICE OF MEDICINE. electuary with some mild confection, I have found to be an excellent remedy in the treatment of this affection. In my lecture on dysen- tery, I mentioned some facts which go to prove that this remedy seems to have great power in bringing down bilious discharges. In this form of jaundice I found cream of tartar extremely useful, and its exhibition is unattended with danger. Now suppose you should meet with a case in which coma appears as an early symptom, what should your line of treatment be ? Here you have to deal with a very threatening symptom, which, if neglected for any time, will, in all probability, bring on a fatal ter- mination. You should, therefore, on its first appearance, meet it with a corresponding activity; you should immediately have the head shaved, apply leeches behind the ears, blister the nape of the neck, and act smartly on the bowels by laxatives. It was by such treatment as this that Dr. Griffin saved his patients. I wish here to make some observations on a very remarkable form of gastro-duodenitis, which was almost epidemic in this country some years ago, at least it occurred during the existence of an epidemic fever, and we had at that time a great many cases of it in the hospital. It is a curious fact that the majority of these seemed to bear a distinct resemblance to the yellow fever of warm climates. This will appear somewhat extraordinary; but, when you have heard a statement of the facts, you will be inclined to think that these cases were nothing more or less than so many instances of the malignant yellow fever of the tropics. I shall read for you an account of the symptoms, as they were observed in numerous cases under the care of my colleague, Dr. Graves, and myself, in the Meath Hospital. In the great majority of cases this disease was preceded by fever; in fact, all the patients who exhibited this form of jaundice had been admitted as fever patients. After a longer or shorter period, with- out any premonitory indications, symptoms of intense irritation of the digestive tube set in, and advanced with a fatal rapidity. Most of the patients vomited frequently; there was great tenderness of the epigastrium, and over the region of the small intestine; the tongue became black and parched; there was a violent pain in the belly, and a spasmodic affection of the abdominal muscles, which felt hard and knotted, and to which the nurses gave the name of twisting of the guts, a name which singularly agreed with the numerous intussusceptions found along the course of the small intestine after death. This state of suffering continued from one to four hours, and then the body became all over suddenly jaundiced. Then came another train of symptoms. With intense and universal jaundice, the patients exhibited also extreme restlessness, tossing their arms about, and regarding their attendants with a look at once expressive of nervous suffering and despair. Some raved, had trembling and convulsive fits, and were totally unconscious of every thing passing around them; others preserved their intellect to the last, but they had depicted in their countenances an agony and a despair which I shall never forget. General spasms were JAUNDICE FROM GASTRO-DUODENITIS. frequently observed; and many, on attempting to swallow, had spasms like those of hydrophobia. There was great irritability of the stomach ; many vomited frequently, and in some cases the matter ejected bore an exact resemblance to coffee grounds. The pulse became low and fluttering, the extremities cold, the face pale and shrunken, and in some the nose assumed a purple colour, giving to the patient a truly horrible appearance. This change in the colour of the nose was preceded by extreme paleness ; the part, at first, appeared as if it had been frost-bitten. Broad patches of a wax-like whiteness, elevated a little above the level of the skin, and somewhat resembling urticaria, having the same temperature as the rest of the body, were found on the following day to assume a reddish colour; and on the third day the redness was converted into dark purple. The toes were affected in a similar way; and in some of these cases the parts so affected sloughed and were thrown off. There is at present in this city a woman who lost the ala of the nose, and one of the toes, in this manner. The phenomena observed on dissection were equally remarkable. Though the tenderness of the epigastrium was very great, there was no trace of peritoneal inflammation ; neither ivas there, in any case, inflammation of the liver, and. the gall ducts were found to be pervious in every instance. The mucous surface of the stomach, and duodenum, and ileum, were found in every case to present intense marks of inflammation ; there were numerous intussuscep- tions along the course of the ileum, and the spleen was found to be large, soft, and pultaceous. There was no evidence of inflammation of the brain; but in the ventricles, and at the base of the brain, there was in some cases an effusion of yellowish fluid, and the membranes had a faint tinge of yellowness. In one case l found a remarkably dry state of the arachnoid. In one severe case there was a good deal of a substance resembling coffee grounds in the stomach, and the mucous membrane was soft and disorganised. All the phenomena of this disease, the gastro-intestinal inflam- mation, the yellowness of skin, the enlargement and softening of the spleen, the rapid fatality and excessive prostration, seem to point out a strong analogy between it and the yellow fever of warm climates. In the writings of Rush and Lawrence, you will find that their description of the phenomena, observed on dissection, would in a great degree answer for those of the cases which I have detailed. I may mention here, too, that in our cases the mortality was severe. We lost the first sixteen cases ; and it was not until we fully ascertained the nature of the disease by dissection, that we began to save these patients. Then, by free depletions, copious applications of leeches to the abdomen, and the bold use of calomel and opium, we succeeded in a great number of cases. In some cases death took place in four, in others in six hours ; in a few it was more prolonged. There is no epidemic on record in this city in which the same symptoms, and the same rapid fatality, were observed. With respect to the analogy between this disease and yellow fever, 112 STOKES’S THEORY AND PRACTICE OF MEDICINE. it appears that in the latter affection the yellow colour depends upon the presence of bile in the blood. This is one point. Again, from the most accurate descriptions which have been given of the morbid appearances of yellow fever, it appears that in the majority of cases the liver has been found healthy ; here is another point. In yellow fever, also, inflammation of the stomach, duodenum, and intestines, is a matter of almost universal occurrence, as you will find by examining the works on yellow fever. In our cases we had all these circumstances; we had extreme tenderness of the epigastrium, and inflammation of the stomach, duodenum, and intestines ; and in one severe case we had black vomit. All these circumstances, combined with the fatality, seem to prove that the cases which were under treatment in the Meath Hospital, during the epidemic of 1846-27, bore a very striking resemblance to that species of fever which is supposed to exist only in warm climates. It is probable that if yellow fever should appear in temperate coun- tries, it would exhibit itself in the form of gastric fever, with some cases only of yellowness. Indeed, it seems to be now very gene- rally admitted, that yellow fever has nothing peculiar in it; that it is the maximum of bilious or gastric fevers. We find that in pro- portion as we approach the warm latitudes, the digestive mucous membrane appears to take on a greater susceptibility of disease. Between the tropics it would seem as if morbid actions were chiefly thrown upon the viscera of the abdomen. Europeans, who have resided there for any length of time, acquire a yellow tinge, and many of them suffer from intestinal and hepatic inflammations. If we go northward, we find the case to be the reverse; as we approach the colder latitudes, we find the mucous membrane of the digestive tube acquires a greater degree of tone and vigour, that it is less sus- ceptible of disease, and can bear much greater stimulation. The inhabitants of warm climates use a large proportion of vegetable food; they seldom indulge in the use of animal food or spirits. The Hindoo lives on rice, the Arab on dates and milk. But, if we go northward, we find the natives habitually using stimulating food and drink with impunity ; indeed, it is wonderful to think what vast quantities of flesh, animal oil, and other stimulants, the stomach of an Esquimaux or Kamschatkan will bear without injury. There is no doubt that warm climates predispose to inflammatory affections of the digestive apparatus, and this seems to connect yellow fever with the ordinary form of gastro-duodenitis, accom- panied with jaundice, or, in other words, a little more extent, a greater degree of intensity, and we may have the jaundice of this country converted into yellow fever. And it is fair to conclude that the typhus icterodes of temperate countries owes its danger not to the mere circumstance of jaundice existing, but to the greater degree of secondary gastro-enteritis which has produced that jaun- dice. I shall now draw your attention to some other forms of jaundice. One of the most important of these is, that which arises from the obstruction of the biliary ducts by calculi. It would be foreign to 113 JAUNDICE FROM GASTRO-DUODENITIS. my purpose to enter into any discussion with respect to the forma- tion of gall stones in a course of lectures like this ; I shall therefore refer you, for information as to their history and composition, to the various treatises on animal chemistry. What we have to con- sider at present, are the symptoms of the disease, the habit of body in which it is found to occur, and its mode of treatment. You see on the table numerous preparations of the various forms of this dis- ease. Gall stones are more commonly observed after the age of forty or fifty than before these periods ; they are very frequently met with in persons of sedentary habits, and hence women are more subject to them than men. They are also liable to occur in persons who eat highly-seasoned indigestible meats, and take little or no exer- cise. It is stated that in England five sixths of the cases of gall stones occur in females. I do not know whether this proportion be exact, but the fact is established that they are more common in females than men. Biliary calculi may be found in three different situations, either in the substance of the liver, or plugging up the biliary ducts, or filling the gall-bladder. Here is a preparation, exhibiting the gall-bladder almost obliterated by the pressure of a number of those calculi within its cavity. Here is another speci- men. You see the gall-bladder is contracted, and nearly filled up with biliary calculi; it also appears to be atrophied and reduced in size. Here is a remarkable specimen. You observe the gall- bladder, which is rather large, is completely filled with a vast cal- culus ; its coats are also thickened, probably the result of inflam- mation. Here is another preparation of the gall-bladder, contain- ing two moderately sized calculi. Gall stones, when lodged in the substance of the liver, or in the gall-bladder, may remain for a long time, and accumulate pro- digiously, without producing jaundice. This has been frequently proved by the fact, that on opening the bodies of persons who have not had during life the slightest symptom of jaundice, the gall- bladder has been found completely filled up with these productions. But when any cause determines the passage of one of these bodies into the ducts, and that it is too large to pass freely, then the symp- toms of icterus begin to make their appearance. We do not know what it is that produces the attempt to discharge small biliary cal- culi through the ducts, but it is during this process that the dread- ful symptoms of what has been by some called hepatic colic are observed, and, supervening on these, the rapid occurrence of jaun- dice. Under such circumstances, a train of phenomena presents itself, very different from that which characterises the jaundice depending on inflammation of the stomach and duodenum. The patient is suddenly attacked with violent pain in the epigastrium and right hypochondrium. The stomach sympathises, and we have nausea, cardialgia, and vomiting; the patient’s sufferings are dread- ful, and he refers his pain to the region of the gall-bladder. The abdominal muscles are thrown into spasmodic contractions, there are often convulsions and fainting fits, the extremities are cold, the STOKES’S THEORY AND PRACTICE OF MEDICINE. body is bathed in perspiration, and the pulse is often hard and con- tracted, but seldom accelerated. This is a very remarkable symp- tom. Heberden says, that the pulse not being in quickness above the standard of health, with a sudden attack of pain in the region of the epigastrium, are diagnostics of this affection. “ I have seen,” says he, “ a patient in this disease rolling on the floor in a state of violent agony, which I could not allay with nine grains of opium, and yet the pulse was as tranquil as if he was in a calm sleep.” I can confirm the truth of this observation from my own experience. Here are the diagnostics ; the pain is more intense than that which attends any form of inflammation, and yet the pulse is perfectly quiet; it occurs in persons not generally subject to spasmodic attacks; it is not preceded by constitutional symptoms; and is rapidly followed by jaundice, and absence of bile in the stools. Under these circumstances you may make a certain diagnosis. Sometimes a tumour is formed in the right hypochondrium, which rises above the edge of the liver, and gives a feeling of dis- tinct fluctuation, marking the situation of the distended gall- bladder. In such cases as these, the calculus is in the common duct, and the bile descends into the gall-bladder, from which it cannot escape, thus causing the distension of that organ. This may go on until the distension becomes so great as to increase the size of the gall-bladder to such a degree, that, in some cases, it has been known to contain a pint of fluid ; and cases have occurred in which it has burst, and effused its contents into the peritoneum, causing violent peritonitis and death. This termination, however, is fortunately of very rare occurrence. I believe that some of the cases in which rupture occurred, were those in which an emetic was given; and hence it is that many practitioners are afraid to give an emetic where this state of the gall-bladder has been ascer- tained, or is strongly suspected.

Bright and Elliotson—Connection with malignant disease exa- mined—Source of fatty matter. We were occupied at our last meeting, in considering the symp- toms of that disease in which there is a formation of what are termed biliary calculi; the passage of these into the common biliary duct; the possible strangulation of the duct for some time, and the conse- quent production of jaundice. I described the symptoms of this disease as consisting in a sudden and violent attack of pain in the 115 JAUNDICE FROM BILIARY CALCULI. region of the gall-bladder, succeeded sooner or later by the pheno- mena of jaundice, and in the generality of cases occurring without fever. Between these violent attacks the patient sometimes has intervals of complete ease ; at other times a gnawing sensation con- tinues in the original situation of the pain. It is remarkable, how- ever, that a patient may have an interval of perfect ease between the fits, somewhat similar to the calm which occurs during the pains of labour. The occurrence of this cessation of intense suffer- ing has been attributed to the passing of the stone into the duode- num ; this, however, is by no means certain. The idea generally entertained upon this matter is that each attack of pain corresponds with the passage of a stone. How far this notion may be true I cannot decide; but this I shall impress upon your attention, that the mere subsidence of pain is no proof of the removal of the disease, unless bile is discharged by stool or by vomiting ; but when such a discharge coincides with the cessation of pain, you may be sure that the obstruction has been overcome for the time. I need not remark to you that the smaller the calculus is, the greater the facility with which it will be discharged. You will find in some cases that the efforts which nature makes to remove one of these concretions are quite unavailing; it lies in the gall-bladder or duct, and there remains impacted. Here its presence sometimes excites inflamma- tion, lymph is thrown out, and the duct becomes permanently closed; in other cases it has been found to make its way into the duodenum by ulcerative absorption, and is thus discharged. The size of biliary calculi is various. Generally speaking, their dimensions are similar to those which you see before you ; but there are many cases on record of very large ones having been discharged. In the twelfth number of the Medico-Chirurgical Transactions, Dr. Brayne gives an instance of one passed, which was three inches long and three and a quarter in circumference. I may however mention, that there is a source of doubt connected with this case. It is possible that the calculus in this instance was nothing more than one of those fatty covered secretions which are found in the intestinal tube, and which have nothing to do with the gall-bladder or its ducts. As it is my intention to return to this subject, I shall here only observe, that fatty matter has been frequently discharged in hard as well as soft masses, that it sometimes cuts like a biliary calculus, and that it may be difficult for a mere physiologist to dis- tinguish concrete masses of this kind from gall stones. The passage of a biliary calculus does not of necessity imply the the occurrence of jaundice ; if it passes without difficulty there is none; if it happens to become impacted, then jaundice is sure to follow. It is a curious fact, that of this form of jaundice cases have occurred in which the flow of bile into the digestive tube has been obstructed for more than a year, and yet a recovery took place. Permit me now to rehearse the diagnosis of jaundice from biliary calculi. Sudden and violent pain in the region of the gall ducts, increased by pressure, but generally unaccompanied by acceleration of pulse or fever, coming on in a person not subject to spasmodic 116 STOKES’S THEORY AND PRACTICE OF MEDICINE. attacks, and speedily followed by jaundice. This is the diagnosis. In most of the cases described in books, and, I believe, in the ma- jority of instances, you will find the disease to exist without febrile symptoms; but it is also true that it may be complicated with febrile disturbance, and under such circumstances you should be apprehensive of inflammation in the biliary ducts or duodenum. The importance of this will appear when you come to consider the treatment. Now, suppose you are called to attend a case of this kind. A person of sedentary habit, who indulges in highly seasoned food and takes no exercise, gets a sudden attack; he lies, perhaps on the floor, writhing in agony; he is beginning to exhibit the yellow tinge of jaundice ; he refers his pain to the region of the gall-bladder; his pulse, however, is quiet, and he has no evident symptoms of fever. Here the nature of the disease is manifest, and the first thing you have to consider is, what are the indications of treatment. These are obviously threefold. The first is to guard against in- flammation ; for you are aware that inflammation may take place, and besides, the higher the irritation and (if I may so term it) the spasm of the gall ducts are, the greater will be the difficulty in passing the stone. The next thing is to allay spasmodic pain. We know that this pain is principally spasmodic, or nervous, because it is always more sudden and violent than that which attends common inflammatory action, and, moreover, it is commonly uncomplicated with symptoms of inflammation. The third indication is to adopt measures to favour the passage of the stone. Now these three indi- cations, but more particularly the second and third, are, as you may perceive, reducible to one form of treatment. Whatever will relieve pain and spasm will assist in favouring the passage of the stone. If, then, you happen to meet with a case of this affection in a strong robust constitution, where the pain is violent and is aggravated by pressure, and particularly where there is any sign of febrile disturb- ance in the system, I would advise you to bleed such a person immediately. Not that you have to combat actual inflammation, but because you have to prevent the liability to it, and because, in using the lancet, you are employing a most powerful antispasmodic. The next thing of importance, in severe cases, is the application of leeches over the region of the gall-bladder, and the same remarks apply to leeching as to venesection. Yon are not to suppose that the application of leeches will cure the disease; but you may be sure that it will assist materially in allaying spasm, and favouring the passage of the calculus. The bowels should be freely acted on by purgatives and enemata; you may give a brisk purgative by the mouth, and at the same time a purgative enema. After the bowels have been opened, the only thing which you can rely upon for giving relief is opium, and that in full doses. I have seen several patients labouring under this disease who appeared to me to be mal- treated. The different measures for procuring relief were certainly put into practice, but not in a regular or proper manner. They first got a dose of opium, then a purgative, and lastly were blooded. JAUNDICE FROM BILIARY CALCULI. 117 If you have a case of this kind to treat, bleed first, then leech, next employ purgatives, and when you have emptied the bowels, have recourse to opium. I have never employed the anodyne injection in this disease; but, reasoning from analogy, I am inclined to think that it would prove serviceable, and I am aware that it has been employed with effect in that form of jaundice which depends upon hysteria. The tobacco injection also seems to have strong claims to our notice, and in this disease must prove extremely useful, from its powerful effect in reducing spasm. There is a difference of opinion with respect to the employment of emetics. The object of their exhibition is to force the calculus through the ducts, by the shock given by the sudden and violent contraction of the abdominal muscles, and also to relieve spasm, by their subsequent relaxing effect. Some practitioners of high au- thority, however, state that this practice is not unattended with danger, and give cases of rupture of the gall-bladder after the exhi- bition of an emetic. Such an accident as this would be very likely to injure for ever the character of a professional man. I am sure the practice, in some cases at least, is dangerous. A distinguished medical friend of mine has related to me the particulars of a case of this kind, in which the exhibition of an emetic was followed by rupture of the gall-bladder and fatal peritonitis. In this instance the case was not so deplorable, so far as the patient was concerned; he was labouring under extensive disease of the liver, and only exchanged a lingering for a sudden death ; but this furnishes no excuse for a medical practitioner. If I were to hazard a conjecture, I would say that emetics can he employed with safety only in the early stage of the disease, when there is no obstruction from or- ganic disease ; for the longer the jaundice has lasted, the greater is the chance of obstruction from organic disease. Again, you should never use them where there is evidence of a distended gall-bladder. If you can feel the tumour formed by the distended gall-bladder, in the right hypochondrium, you may be sure some- thing has been going on for a long time, and you should be cautious in giving an emetic. Never use it then where you can feel a tu- mour in the region of the gall-bladder. If you give it at all, give it in the early stage, and after premising venesection, leeching, and the use of the tobacco injection. I had almost forgot to mention that very signal advantages accrue from the use of the warm hip bath in this disease. I have seen cases in which the most extra- ordinary relief was obtained by applying twelve leeches over the region of the gall-bladder, and then placing the patient in a hip bath. Sometimes it happens that the symptoms return again and again. Here you cannot repeat the venesection ; you must employ leeches, the hip bath, warm fomentations, opium, and every thing calculated to relieve pain and spasm. Watch your patient carefully, guard against inflammation, and if any inflammatory symptoms of the duo- denum arise (but this is rare) take proper measures to obviate them. 118 THEORY AND PRACTICE OF MEDICINE. A few words now with respect to what has been termed spasmo- dic jaundice. This form of the disease occurs independent of inflammation of the stomach or duodenum, and independent of dis- ease of tiie ileum, brain, or liver. It appears to be an essentially spasmodic disease, but the situation of the spasm has not as yet been accurately determined. It is supposed to exist, either in the gall- bladder, or in the biliary ducts, or in the duodenum. If the biliary ducts and gall-bladder do not possess muscular fibres, we must place it in the duodenum; but whatever may be its seat, it presents the characters of a spasmodic disease. It seems to be excited by the same cause, and yields to the same treatment as other spasmodic affections. It generally occurs in hysterical females, and in hypo- chondriac and nervous persons, and disappears under treatment calculated to allay nervous excitement. Its exciting causes seem to be chiefly sudden and violent mental emotions, or the taking of a quantity of indigestible food ; and it frequently terminates by the discharges of flatus upwards and downwards. It resembles, in a certain extent, the last-mentioned form of jaundice, but differs in two particulars ; first, the pain is relieved by pressure, which ge- nerally increases it in the former species. Dr. Pemberton, in his Treatise on the Diseases of the Abdominal Viscera, dwells strongly on this point. The second peculiarity is, that in this disease the attack is more sudden. In the case of jaundice from gall-stones, the patient has some degree of pain and uneasiness before the vio- lent symptoms appear ; but in this form they exhibit themselves in a sudden and unexpected manner. The disease, too, is accom- panied with hysterical or convulsive symptoms, and there is some- times a copious flow of limpid urine. All these circumstances are important in forming a correct diagnosis. The best treatment for this spasmodic jaundice is, after acting on the bowels by warm purgatives, to use fetid enemata, and prescribe a mixture composed of ether, castor, and ammoniated tincture of valerian and opium, which are of the greatest use when the bowels have been opened. In this form, as well as that which we have been lately considering, the fact is, that if you expect any good from opium, you must not give it until the bowels have been opened. Opium and antispasmodics have, I am convinced, often lost their character for utility, from being given at a time when the exciting causes of disease are still present in full energy; and the failure of these powerful auxiliaries is to be attributed to the neglect of proper measures for reducing intense irritation. In the spasmo- dic jaundice, tobacco injections would be likely to produce bene- ficial effects. Generally speaking, however, you will not find it necessary to have recourse to such a vigorous remedy, as the disease is most commonly observed in delicate females, and yields readily to milder treatment. Indeed, it will often disappear sponta- neously, and without any apparent cause. The last form of this disease which we have to consider, is jaun- dice connected with an affection of the brain; and this is a very interesting and curious subject. I shall not, however, enter upon JAUNDICE FROM BILIARY CALCULI. 119 it at present, as I intend to reserve my observations on this point until we come to treat of diseases of the nervous system. I have alluded to this variety on a former occasion, and referred you to Dr. Marsh’s paper on jaundice in the Dublin Hospital Reports, in which you will find several cases of it which came on as the result of disease in the head. Broussais admits that it is dependent on and secondary to cerebral disease; but he thinks there is another link in the chain of connection, and that this is duodenitis. He believes that we have irritation, first in the brain, next in the duo- denum, and then jaundice. Several practitioners of great authority, on the other hand, assert that the cerebral affection produces jaun- dice at once, without the intervention of duodenal inflammation. In the present state of medical science we cannot determine this point. A few observations now with respect to the discharge of fatty matter from the bowels. The reason why I introduce the subject here is, because it has been frequently observed in connection with jaundice and disease of the upper portion of the digestive tube. In the last number of the Medico-Chirurgical Transactions, a great mass of interesting matter has been published on this subject by Dr. Bright, Dr. Elliotson, and Mr. Lloyd. I shall give you a short analysis of these papers; and I wish to impress this upon your recollection, that when you go into practice the study of this affection would form a subject worthy of your investigations ; and that any attempts on your part to clear up the difficulties which complicate this singular form of disease will be advantageous to the cause of science. Dr. Bright gives three interesting cases of this disease. In these the discharge was in the form of oil or semi-concrete matter-—it floated on the top of the faeces, and had a fetid odour. There was also in these three cases a remarkable similarity in the pathological phenomena. The first case exhibited symptoms of jaundice, dia- betes, enlarged liver, and discharge of fatty matter: on dissection, the liver, pancreas and duodenum were found diseased. The second presented symptoms of jaundice and disease of the liver, in addition to the fatty discharge; on dissection the liver was found healthy, but there was a similarly diseased condition of the duo- denum and pancreas ; there was malignant disease in both. Nearly the same symptoms were observed in the third case, and after death disease was found in the pancreas and small intestine, and the pylorus was in a state of extensive ulceration. In alffthere was chronic disease of the pancreas and duodenum terminating in jaundice, from ob- struction of the gall duct, and accompanied by discharges of fatty matter from the bowels. Here are three cases in which there is an extraordinary similarity in the symptoms and pathological appear- ances. Dr. Bright is inclined to think that these discharges may he connected with disease of the pylorus and duodenum, but par- ticularly with malignant affections of the pancreas, and gives the particulars of some cases, in which disease of the pancreas was sus- pected, and in which, from the absence of this symptom, he was 120 STOKES’S THEORY AND PRACTICE OF MEDICINE. induced to give a contrary opinion, which, on dissection, turned out to be correct. Mr. Lloyd’s case resembles those detailed by Dr. Bright, inas- much as it presented the phenomena of jaundice with obstruction of the gall ducts, disease of the head of the pancreas, and contrac- tion of the duodenum. So that you see we have here four cases in which there was disease of the duodenum and disease of the pan- creas, together with the occurrence of jaundice. I may, however, mention one fact, which you should be acquainted with ; in Mr. Lloyd’s case the pancreatic duct was found to be obstructed by calculi. Dr. Elliotson commences his paper by alluding to that peculiar substance called ambergris, which is frequently washed ashore by the tide in several countries, and which is supposed to be a morbid production from the intestinal canal of the physeter macrocepha- lus, or spermaceti whale. The quantity found in the intestinal canal of this animal is said to be enormous, and instances are mentioned, in which this substance was found to amount to 182 lbs. in the body of one of these animals. Dr. Elliotson proceeds to give cases from the records of medicine and from his own experience, in which a fatty discharge took place in the human subject. Of this he quotes cases from Masllenbrochus and Maebius in the Ephe- merides, but one in particular from the works of Fabricius Hildanus, which I shall briefly recount. “ A pious matron of Hilden had been for a long time subject to severe pain in the stomach, which became at length much worse, when one day the pain extended all over the abdomen, and after very severe pain and suffering, she discharged about three pounds of fat, which was of a pure quality, had no smell, and was preserved by her for many years.” This woman recovered perfectly. Dr. Scott, of Howick, mentions the case of a servant girl who had been treated with purgatives and injections, under the supposition that her disease was colic, and who, after two or three days’ suffering, discharged a quantity of fatty substances, about the size of nuts, beans, and peas, which burned like fat when thrown into the fire; this patient also re- covered. Dr. Babington gives another case, which had been mentioned to him by Sir E. Home, in which we find that a lady who had been suffering, as it was supposed, from gall stones, happening to take castor oil draughts to open her bowels, passed a quantity of fatty matter. Another case is detailed by Mr. Howship, where a lady who had been attacked with pain, jaundice, and fever, passed a quantity of this substance with the subsidence of those symptoms. The fatty matter in this case was discharged after the lady had taken a pint of olive oil, upon the recommenda- tion of Dr. Simpson of New Malton. Dr. Turner, of St. Thomas’s Hospital, mentions the case of a female who laboured under an hysterical distension of the belly, and who passed quantities of this substance, specimens of which are preserved in the Hunterian Museum. Sometimes these fatty discharges are found in the concrete, some- JAUNDICE FROM BILIARY CALCULI. 121 times in the semi-fluid form. Dr. Elliotson mentions the case of a patient who had phthisis, diabetes, and discharge of fatty matter ; thus he was at the sam§ time passing fatty substance, large quanti- ties of saccharine urine, and spitting up pus and softened tubercular matter. Between all these, and the agonising pain which he suf- fered, he became in a short time completely exhausted and sank rapidly. The fatty matter discharged in this case was shown to Dr. Prout and Mr. Faraday, and Dr. Prout stated he could not distinguish it from human fat when heated. Tulpius is quoted by Dr. Elliotson as relating a case where fat ivas discharged from the bowels and bladder. Here is the quotation :—“ But what do we say of Margaret Appelmania, an innkeeper, who, in her seven- tieth year, passed precisely the same fat, both from the intestines and the bladder, and likewise without fever, emaciation, or colli- quative excretion. Towards the close of the disease, however, she did become feverish, and, in consequence, so emaciated, that death found her little else than a juiceless dried up corpse.” A case similar to this was communicated by Mr. Pearson to Dr. Elliotson. The symptoms were suppression of the biliary secretion, and a copious discharge of oil from, the bowels and bladder, which, it is stated, formed good soap when mixed with alkali. Dr. Prout has observed fatty matter passed with the urine, and considers this symptom as an indication of the probable supervention of malig- nant disease of the kidneys and bladder. The last case is from the Annali Universali, which is quoted by Dr. Johnson in the Medico- Chirurgical Review for July. In this case the patient, after fasting for a considerable time, took a quantity of indigestible food. On the evening of the same day he had an attack of vomiting ; at first blood was thrown up, and then he ejected this fatty substance to the enormous amount of thirty pounds. There was, in this instance, a sudden and extraordinary emaciation ; the patient was so reduced in the space of a few hours, that the skin hung in loose folds about him. He recovered in twenty days; but with great loss of bulk. Let us enquire now what is the nature of this symptom. Is this fatty matter a morbid secretion from the liver, from the pancreas, from the mucous membrane of the stomach, or from the intestines? There are facts to show, that in certain cases this disease cannot be explained by a reference to any of these circumstances. It seems plain, too, that Dr. Bright’s suggestion of referring it to ma- lignant disease of the duodenum and pancreas, and the diagnosis which he would seem to found upon it, cannot stand here ; for the symptom upon which he attempts to establish a diagnosis—a dis- charge of fatty matter—occurs in persons who have recovered from the disease. We cannot suppose that they have been labouring under malignant disease of the duodenum and pancreas when they have recovered ; and that a recovery may take place is proved by Dr. Elliotson’s cases. It is quite probable, however, that if the irritation, or whatever it be that produces this discharge, should continue, it may bring on fungoid and malignant disease; but that 122 STOKES’S THEORY AND PRACTICE OF MEDICINE. the discharge of fatty matter is significant of the actual existence o f such a condition is not borne out by these facts. Well, are we to look upon this discharge as a secretion from the liver ? I think we cannot, because we have seen that in Dr. Bright’s three cases the biliary duct was obstructed by disease of the duodenum and pancreas. I may mention, too, that in some cases where a dissec- tion was made, the liver was found perfectly healthy, and the gall- bladder in its normal condition, full of pure bile. Taking this and the foregoing fact into consideration, we have proofs that this fatty substance, in some cases at least, cannot come from the liver. Does it proceed from the pancreas ? It would more naturally come from the liver than the pancreas, for the liver does actually secrete a certain quantity of fatty matter ; but there is no substance of this kind found in the secretion of the pancreas, which is considered to bear a strong analogy to that of the salivary glands. Besides, in the case mentioned by Mr. Lloyd, where the duct of the pancreas was obstructed by calculous secretions, this fatty matter has been discharged; and hence we cannot, I think, refer it to the pancreas. Whence, then, does it come ? Is it a secretion from the surface of the intestines ? This is a question which it is hard to determine. We do not yet know, nor have we ever met with that state in which lesion of structure in the mucous membrane of the intestinal canal has been followed by a discharge of fatty matter. We have discharges of serum, lymph, blood, and pus, from the surface of the intestines, according to the nature of the disease; but we know of no pathological condition as the result of which fatty matter may be produced. Again ; cases of every known form of disease in the liver, pancreas, and intestinal canals, occur without this discharge at all. In the present state of medicine, the probability is that this discharge is the result of a sort of metastasis of the secretion of fat from the other parts of the body in which it is usually deposited, to the surface of the digestive tube, where it is poured out somewhat in the same way as in cholera; the fluids of the body are rapidly absorbed and eliminated by the intestinal canal. This supposition, without attempting to bring it forward as the true solution, fur- nishes us with the best explanation of the case. In the case of the patient who discharged this substance by stool and with the urine, the emaciation came on rapidly, as if all the fat of the body had been absorbed and carried out of the system; here, too, the fat was discharged from another mucous surface. In the other remarkable case, where a vast quantity of this substance was thrown up by vomiting, the emaciation was so great that the patient's skin hung in loose folds about him. When we reflect, too, that there is no recognised disease of the intestines, liver, or pancreas, to which this discharge can be referred, we cannot help believing that it is the result of a metastasis in the secretion of fat. The next point in this matter which we have to consider is, what is the best mode of treatment ? This question, I believe, cannot be answered at present; nor can our practice be any thing but empi- rical until we have more light throw upon the subject. With a ACUTE AND CHRONIC HEPATITIS. 123 view to increasing our knowledge, I beg of you to make this disease the subject of your practical investigations, and to have a look out for this discharge, because I believe it often occurs unnoticed, from our neglecting to inspect the evacuations. LECTURE XV. Acute and chronic hepatitis—Pathological differences—Effect of climate—General and local symptoms—Character of fever—Pain of shoulder—Use of pleximeter—Com- plication with jaundice—Resolution—Abscess—Various openings of the latter— Cicatrisation. I propose to-day to draw your attention to the subject of inflam- mation of the liver. This is the disease which you meet with in books under the general name of hepatitis; but it is of great im- portance to distinguish between acute and chronic hepatitis for this reason—acute hepatitis implies something specific, an organic change, the nature of which is well known and accurately defined; but chronic hepatitis implies nothing of this certainty of the nature of organic change, inasmuch as there is no single one of the recog- nised disorganisations of the liver, which may not, and have not occurred, with chronic hepatitis as an existing cause, or a promi- nent symptom. When we speak of acute hepatic inflammation, we speak of a disease, of which the structural lesions are sufficiently understood ; but when we treat of chronic hepatitis, we treat of a disease in which there may be a great variety of organic changes. Chronic irritation of the liver may in one patient be followed by the development of hydatids ; in another by cancer, or tubercle ; in a third, by hypertrophy of one or both of its elementary tissues ; in a fourth, by atrophy; and in a fifth, by abscess ; so that, under the chronic form of hepatitis, we may have many different lesions com- prised. Under the acute form, we have only vascularity, soften- ing, yellow degeneration, and suppuration. These, which are the ordinary results of acute hepatic inflammation, are the same as the results of active inflammation of other parenchymatous organs. It is an interesting fact, and connected with the predisposition to acute diseases of the abdominal viscera in warm climates, that acute hepatitis is much more prevalent in those countries than it is here, and this is particularly true with respect to the East Indies. You recollect, in one of my lectures, I alluded to the greater suscepti- bility to disease, the extraordinary nervous excitability of the digestive mucous membrane in warm latitudes, and hence that a large proportion of the diseases of those climates was characterised by the predominance of inflammation in the stomach and intestines. The same thing occurs with respect to the organs which are con- nected with the digestive tube ; and hence it is that diseases of the liver and spleen are so frequently met with between the tropics. 124 STOKES’S THEORY AND PRACTICE OF MEDICINE. A very remarkable fact, bearing on this point, has been mentioned to me by Staff-Surgeon Blest. He states that, in the East Indies, hepatic disease in animals is no unusual occurrence ; that animals brought to India from more temperate climates are peculiarly subject to it; and that in them it is a common cause of death. He has seen many cases of hepatic abscess in dromedaries and horses, under these circumstances ; a fact of great interest, when considered with the liability to tubercle in animals brought from warm climates to these countries. In these countries, acute hepatitis in its highest degree is a rare disease; in fact, so rare, that it is only in our own time that any thing like a series of cases, by which you could compare the disease in these countries with a similar affection in others, have been published. A series of cases by Louis, and another by Dr. Graves and myself, published some time since, are all that we have on the subject. It is.somewhat extraordinary that a sort of epidemic tendency to acute hepatic inflammation, and the formation of abscess, occurred in the coun- tries about the middle of the year 1828. Up to this period, abscess of the liver was looked upon as a very rare disease in Ireland; a case of it was met with in hospital once perhaps in twelve months or two years ; but at the period to which I allude, almost every great hospital in Dublin had several cases ; and in the Meath alone we had a great number, out of which seven or eight proved fatal. We have now to consider this acute inflammation of the liver; and first, with respect to the symptoms. Were I lecturing on pathology merely, I would commence with the organic changes ; but as I have chiefly kept in view, during my present course, the practice of medicine, I shall begin by detailing the symptoms. You will get a good idea of the symptoms of acute hepatic inflam- mation by dividing them into local and general; by doing this, you will simplify the matter, and acquire accurate and defined notions of the disease. Now, the local symptoms are, pain in the region of the liver, tenderness over the affected organ, and a degree of tumefaction perceptible to the touch; pain, tenderness, swelling— here are the local symptoms. What are the general ? Inflamma- tory fever, and lesion of the digestive function; and, in addition to this, if the case be severe, you have functional derangement of the respiratory and cerebral systems. You have, then, in a case of acute hepatitis, the general symptoms of inflammatory fever, with lesion of the digestive function; and if the case be severe, of the respiratory and even cerebral systems, the local symptoms being pain, tenderness, and tumefaction. Now, with respect to the character of the fever which accom- panies this disease, it is in all cases nearly the same; and here we come to an interesting and curious fact. You recollect that, in speaking of gastro-enteric inflammation, I alluded to the nature of the accompanying fever, and stated that it was (commonly) of a low character, and that there were no local inflammations in which the fever was so often typhoid as in the affections of the gastro- intestinal surface. This, I believe, has been one great cause of the ACUTE AND CHRONIC HEPATITIS. 125 ignorance of medical practitioners with respect to gastric and enteric inflammations; they have been most commonly looked upon as cases of typhus, and treated accordingly. In acute hepatitis, however, we do not observe this typhoid prostration. Though closely connected with the gastro-intestinal system, the liver does not, in its acute inflammatory state, produce the same manifest depression of the vital powers. On the contrary, we have, in the early period of the disease in this country, high inflammatory fever, hot skin, and full bounding pulse; a state in which few would be afraid to employ the lancet with boldness. Patients labouring under acute inflammation of the liver, generally have high sympathetic fever, a full, strong, and accelerated pulse, with the local symptoms above described; and, in addition to these, we frequently observe bilious vomiting, considerable thirst, derange- ment of the bowels, and scanty high-coloured urine. The tume- faction is more or less evident, and when this is accompanied by severe pain, there is considerable difficulty of breathing, a circum- stance which sometimes occasions this disease to be mistaken for pleurisy. There are two remarks to be made on this subject. In the first place, it sometimes happens that acute inflammation of the liver and of the lower part of the lung occur at the same time, particularly where inflammation attacks the diaphragmatic surface of the liver. Here you frequently have an extension of the inflam- matory process to the corresponding surface of the pleura, or the two diseases co-exist from the first. Under such circumstances, disputes, as to which organ is engaged, are often unnecessary. Again, in the early period, and when the attack is acute, the diagnosis of inflammation of the diaphragmatic surfaces of the liver, or pleura, is comparatively of little consequence, as both demand the use of calomel and opium, leeches and the lancet; and, in the early stages at least, both are amenable to the same traetment. But it is not so in the chronic stage of either. Here the diagnosis is of great importance; and when I come to treat of pleuritis, I shall draw your attention to some researches of mine on this subject, which I hope have set this question at rest. The pain which accompanies acute hepatitis varies much in situation. Sometimes it is felt in the shoulder, sometimes under the short ribs, sometimes in the loins, and frequently in the epigastrium. You have all heard of pain at the top of the shoulder as a common symptom of liver disease ; in fact, so common as to be looked upon by some as a pathognomonic symptom. I believe that a great deal too much stress has been laid on this circumstance. It is now discovered, that so far from being a constant, or even a common, symptom, it is one which is of exceedingly rare •occur- rence. I have never seen a case of acute hepatitis with pain in the shoulder; I have sometimes observed it in chronic, but never, to my recollection, in acute cases. Andral states that it is very seldom met with; Dr. Mackintosh says the same, and, if I recollect aright, looks upon it as a symptom not worth enquiring about. Now, I have seen some medical men who considered this pain in the 126 STOKES’S THEORY AND PRACTICE OF MEDICINE. shoulder as a diagnostic of such value, that if it happened to be absent they concluded there was no hepatic disease. The fact is, that it is any thing but constant. You may have it in some cases, particularly of chronic hepatitis, and not in others; besides, it fre- quenly depends upon other causes—for instance, upon pneumonia of the top of the right lung, or it may be caused by incipient phthisis, aneurism of the arteria innominata, or right subclavian artery, and other diseases. It is of very little consequence whether it be absent or present; and the only reason why I dwell upon it is, to show you its real value as a symptom. There is one remarkable circumstance connected with the pain of an acute hepatitis. In one case, you will find that the pain is very acute and constant, in another, that little or none is felt; and when you come to investigate the cause of this after death, it gene- rally happens that, in cases where the pain was violent, the inflam- mation existed on the surface of the liver, and in those where little suffering was experienced, deep in the substance of that organ. This is a curious fact; but it may be looked upon as an illustration of a general law, that if we consider inflammatory affections of the solid viscera, we shall find that the more superficial the inflam- mation the more painful it is ; and, on the other hand, the more deep-seated it is the more is it latent, so far as pain is concerned. Thus : if you take a case of inflammation of the substance or cen- tral parts of the brain, you will find that the disease is to be recog- nised often not by pain, but by the lesions of the sentient and locomotive powers; whereas, in inflammations of the membranes, on the surface of the same organ, one of the most prominent symp- toms is agonising headache. In the next place, go to the lung; take a case of deep-seated pneumonia, and contrast its almost pain- less character with the lancinating torture of an acute pleuro- pneumony. In pneunomia the pain is dull, and scarcely complained of; but pleuritis unaccompanied by acute suffering is extremely rare; in fact, where you have the signs of inflammation of the parenchymatous tissue of the lung, with sharp pains in the chest, you may very safely make the diagnosis of pleuro-pneumony. The same absence of pain is by no means unusual in inflammatory affec- tions of the mucous membrane of the intestines ; but if the inflam- mation should chance to extend to its peritoneal investment,, you will have this state rapidly exchanged for one of intense suffering. So it is with respect to the liver; disease on the surface of that organ is attended with severe pain ; but enormous destruction of its deep-seated parts may take place, and your patient complain merely of a sense of uneasiness. A late author on hepatic affections, Dr. Bell, who has written a treatise on the diseases of India, describes two forms of acute hepatic inflammation, which are different as to their seat and character. In one of these, which he terms sero-hepatitis, the disease is on the surface of the liver; in the other, which he terms puro-hepatitis, it exists in the centre. In the sero-hepatitis, he states that the patient is attacked with sudden pain in the region of the liver, and ACUTE AND CHRONIC HEPATITIS. 127 this is so severe that even the weight of the bed-clothes is insupport- able ; the patient cannot bear to turn or lie on his left side, from the pressure exerted in that position on the inflamed organ. But the deep-seated, or puro-hepatitis, may go on in such a latent manner, that the first symptoms you have of the existence of liver disease are those which mark the occurrence of suppuration. Neither the patient nor his medical attendant will have reason to suspect inflam- mation of the liver, until the constitutional and local symptoms of the suppurative process direct attention to that organ. Such are the statements of Dr. Bell, which I believe to be correct, as they are supported by the concurrent testimony of many persons who have practised in India, with whom I have conversed on this subject. Mr. Annesly makes the same assertion; and such was our expe- rience in the succession of cases of hepatic abscess which were under treatment in the Meath Hospital during the year 1828. The next symptom which we have to consider, is the tumefac- tion of the liver, and this is one of considerable importance. In order, however, to estimate the extent of this tumefaction with any degree of accuracy, you must take one preliminary step, and that is, to have the bowels fully evacuated. If the intestines are filled with feculent matter or gas, you cannot do this in a proper manner. A few hours before you make your examination, give the patient a full purgative draught, assisted, if necessary, by a strong purgative enema. In this way, you empty the belly of collections of feculent matter and aeriform fluid, and then you can with certainty and satisfaction ascertain the extent of the swelling. You will then be able (when your patient is laid in bed), perhaps, to see at once the extent of the tumefaction, particularly where the parietes are not thick or loaded with fat; at all events, you will be able to feel it with your hand, and in every case you can ascertain it by mediate percussion with the pleximeter. I do not know any more important adjuvant, in making out the diagnosis of an enlarged liver, than the use of mediate percussion. For instance, suppose you have a patient labouring under acute hepatitis, and that the tenderness of the organ is so great that he cannot allow you to make the requisite degree of pressure to ascertain the extent of the swelling; take the top of your stethoscope, apply it over the region of the liver, make use of light percussion, and you will find, with the greatest accu- racy, how far the tumefaction of the liver extends, by the dulness of sound heard over the inflamed organ, and exactly limited to it. In this way, you can make a most satisfactory examination, without giving your patient any pain; and this is a matter of some import- ance, as you will meet with many cases in which there is exquisite tenderness, and where the patient will not bear the slightest pres- sure. I would advise you, therefore, to practise this mode ; it gives little or no pain, it is exceedingly simple, and I have not the slightest doubt of its accuracy. Now, the value of this tumefaction, as a sign of the existence of hepatic inflammation, depends very much on the recent nature of the attack. If a man, who was in perfect health a few days back, complains of pain in his right side, and 128 STOKES’S THEORY AND PRACTICE OF MEDICINE. has a tumour in that situation, it is to be presumed that this tumour does not depend upon the presence of a collection of fluid in the pleura, and, consequently, that the tumefaction is not produced by an empyema. Then, if, in connection with fever, and pain in the right side, you can ascertain the existence of a tumour in the region of the liver, and that it has occurred within a short space of time, you may be pretty sure that it is not an empyema, but an inflamed and enlarged liver. Jaundice has also been considered as a symptom of hepatic inflammation, but it is one which is by no means constant. Again, you may have most extensive hepatitis, with slight jaundice, and universal and intense jaundice, with trifling or no hepatitis; and, what is equally singular, you may have very little perceptible dis- ease of the liver with scanty secretion of bile; and, on the other hand, the liver may be burrowed with abscesses, and at the same time you find bilious stools, and after death the gall-bladder may be found filled with pure healthy bile. I thought, at one time, that I could explain the presence or absence of jaundice in cases of hepatitis, by supposing that, where it occurred, the jaundice was the result of inflammation of the gastro-duodenal mucous membrane ; and to prove this, I drew up a table of cases, of which one half were complicated with jaundice, and the other not. I found, how- ever, that in a great number of cases, where the tube was free from disease, the hepatitis was complicated with jaundice; and in a similar number of cases, where the same circumstances were observed, the tube was in a state of disease. So that we may have, as you perceive, hepatitis and jaundice, with and without disease of the intestinal tube; and whether we look to the cases of hepatic inflammation, unaccompanied or complicated with jaundice, the state of the gastro-intestinal mucous membrane throws, as yet, no light on the subject. It appears, then, that the occurrence or non- occurrence of gastro-duodenitis does not explain why it is, that in one case of hepatic inflammation jaundice is a prominent symptom, and in another is completely absent. In some cases of acute inflammation of the liver, the natural secretion of that organ seems to be totally annihilated. A curious case of this kind occurred under the care of Dr. Graves, in the Meath Hospital, where the slightest trace of bile did not exist in the gall-bladder, which was filled with a transparent mucus. In some instances you will find plenty of bile discharged, in others none; in some patients the stools are observed to be clay-coloured, or very faintly tinged with bile ; in others they are healthy, and natural in colour, as well as consistence. From our own experience, and from studying the series of cases published by Louis, we have come to the conclusion, that neither the presence nor the absence of bile in the stools affords any positive or useful information as to the different stages of this disease, its progress or termination. Acute hepatitis terminates in a variety of modes. It may termi- nate by resolution—here the organ returns to its former healthy- state, without any appreciable change of structure or function ; it ACUTE AND CHRONIC HEPATITIS. 129 may terminate by the formation of matter—here we have suppura- tion and abscess ; it may terminate in gangrene ; and, lastly, it may, without the occurrence of suppuration or gangrene, pass into chronic hepatitis, of which the result may be a variety of morbid changes in the organ itself. When the patient is so fortunate as to meet with the first of these terminations, the fever, pain, and tume- faction, gradually disappear. On making an examination with the pleximeter, you will find that part of the belly which was rendered dull by the tumefied liver becomes clear on percussion; you will find, also, that the dulness of the lower part of the chest, on the right side, is removed, the patient can breathe without any difficulty, and lies on the afFected side without inconvenience. But when the disease passes into the suppurative stage, the train of phenomena exhibits a marked difference. What we generally observe under such circumstances in this country is, that there is a change in the constitutional symptoms; the fever, which has been hitherto inflam- matory, now becomes hectic. The pulse continues quick, but is diminished in strength and volume ; the countenance becomes pale and collapsed, the patient feels languid, restless, and disposed to sweat, and his perspiration has a sour smell. He may also have a miliary eruption, and this continues for some time, with an increase or persistence in the size of the hepatic tumour. When these symptoms appear, there is every probability that matter is forming, or has been already formed. The patient then begins to complain of increased weight in the region of the liver, and in some cases the integuments over that organ are swollen, and slightly discoloured. I have observed that, in some instances, the pain concentrated itself in one point, and in this situation it was afterwards found that abscess had formed. These are the ordinary symptoms which usher in, or accompany, the suppurative stage of hepatic inflamma- tion ; but there are also cases, even in this climate, where this marked change of symptoms is not seen, and where abscess forms rapidly, and with symptoms which might be supposed to belong to the early period of the disease. This, however, is particularly true with respect to hepatic abscess in the East Indies. I believe I mentioned in a former lecture a very curious fact, namely, that it has been often found impossible to salivate persons labouring under hepatic abscess, so that the presence of matter or not, in the liver, may be determined by the circumstance of the patient being susceptible or not of the full effect of mercury. The liver, in this case, seems to illustrate that pathological law which I alluded to in speaking of dysentery; that the more intense an inflammation, the greater is the difficulty of producing ptyalism. My friend, Staff-Surgeon Marshall, and also Mr. Annesly, agree in stating, that it is exceedingly rare to find a case of hepatic abscess in which the salivary glands have been affected by mercury, and our experience of the disease in this country exactly coincides with their opinion. It has been also observed, that hepatic abscess may form in an insidious and latent manner, when it happens to be com- plicated with disease of other organs. This affords us an illustra- 130 STOKES’S THEORY AND PRACTICE OF MEDICINE. tion of a law already laid down, that the more complicated an affection is, the more obscure is its character. Again, we may, as the result of acute hepatitis, have one or two vast cavities formed in the substance of the liver, or we may have a number of very small abscesses. I recollect a case which occurred some time ago near this city; the patient exhibited the symptoms, and was, in fact, supposed to labour under intermittent fever. After some time, death took place, and, on dissection, a number of small abscesses were found in the liver, of which, during life, there was no symptom, except that which I have just mentioned. When an hepatic abscess attains a certain magnitude, it has a tendency to burst and discharge its contents. If it escapes exter- nally, it makes its way in a great variety of directions, sometimes in the epigastric, sometimes in the hypochondriac, sometimes in the lumbar region, and there are cases on record, in which the matter has burst in the right axilla, by a sinuous passage beneath the integu- ments of the chest. When it bursts internally, it sometimes perfo- rates the diaphragm, and gets into the cavity of the pleura, or, what is more commonly the case, into the substance of the lung. The matter of an hepatic abscess very rarely gets into the pleural sac, and hence we very seldom have an empyema as the result of this occurrence, because the pleura being extremely liable to adhesion as a consequence of the inflammatory process, and the passage of matter being always preceded by inflammation, the opposed sur- faces of the pleura become glued together by coagulable lymph, which prevents the hepatic pus from getting into the pleura, at the same time that it favours its passage into the lung. The opening into the lung is one of ordinary occurrence; many cases of it are on record; and serious as the lesion may appear, it is, perhaps, one of the best modes in which hepatic abscess may terminate by inter- nal opening. Many persons have recovered after such a termina- tion ; and I have seen myself three cases in which it was certain, and a fourth in which it was probable, that the matter had been expectorated by the mouth, with a favourable issue. We are, then, as far as the records of medicine and our experience in the Meath Hospital go, warranted in looking on this termination as a favour- able one. Hepatic abscess may also open into the pericardium; but this is very rare, there being only one case of this kind, which is given by an American author. It may open into various parts of the intestinal canal, the stomach, duodenum, and colon; it may also discharge its contents into the right kidney, into the vena cava, or into the peritoneum, and thus cause violent peritonitis and death. The diagnosis of these different openings of an hepatic abscess is easy, and founded on the same principle, the occurrence of new and extraordinary symptoms, connected with the adjacent viscera, which were not before diseased—symptoms of a sudden discharge of pus from, or into, these organs. Suppose you have a case of hepatic abscess, and that, during the progress of the disease, the patient has sudden and enormous expectoration of purulent matter, without any preceding signs of inflammation of the lung, it is probable that HEPATIC ABSCESS. 131 the abscess has opened into the lung; or suppose that, during an attack of acute hepatic disease, your patient is all at once seized with nausea, and vomits a quantity of purulent matter, and, imme- diately after this, you perceive that the tumefaction of the liver sub- sides. Here the matter has been discharged into the stomach; in other cases you have it discharged into the duodenum or colon. Again, you may have instances where the matter gets into the peri- toneum ; here you may observe the occurrence of rapid peritonitis. So that, in all cases of this kind, the diagnosis is founded on the same principle, the occurrence of discharge of pus from, or into, organs which previously had been considered to be in a healthy state, and this coinciding with a subsidence of the original tumour. In persons who, under such circumstances, recover, it is natural to expect that cicatrisations should exist in the liver. Louis states that he has never seen this ; with respect to our cases of hepatitis, we can only say that the fatality of the disease has afforded us no opportunity of investigating this point of morbid anatomy. Mr. Annesly, however, in his work on the diseases of India, has given drawings exhibiting this appearance. I recollect one case of a man in the Meath Hospital, who had been a soldier in the East India Company’s service, and had been treated for liver disease ; this man died of phthisis, and, on dissection, the surface of the right lobe of the liver was found puckered, forming a hollow with a cartilaginous basis, strongly resembling what we might suppose to be the cicatrix of an abscess. LECTURE NYI. Diagnosis of the rupture of hepatic abscess—Pulmonary openings—Case of double opening—Puncture of the gall-bladder—Gangrene of the liver—Its connection with hepatic apoplexy—Diagnosis of distended gall-bladder—Its causes—Inflammation of the parietes over the liver—Sympathy of the integuments. I broke off at my last lecture while engaged in considering the phenomena of hepatic abscess, and you will recollect I spoke of the various modes in which these abscesses may open internally, and stated that the diagnosis in all cases was founded on the same prin- ciple, which is this—that during the prevalence of symptoms indi- cating the existence of suppuration of the liver, some new organ becomes suddenly affected, the nature of the affection being what would be produced by the sudden rupture of an hepatic abscess and and a discharge of pus into some of the neighbouring viscera, and this coinciding with the disappearance, more or less, of the original tumour. Now, when we consider the various internal openings of an hepatic abscess, we find that they admit of being divided into two classes, first, those in which the matter is effused into cavities 132 STOKES’s THEORY AND PRACTICE OF MEDICINE. having- a communication with the exterior of the body, as the lung, digestive tube, and kidney. Here, in addition to the symptoms already alluded to, we have a sudden discharge of pus from the stomach or bowels, from the lungs, or by the urinary passages. But we may also have the matter discharged into shut cavities having no external communication, as where the contents of the abscess open into the peritoneum, pleura, or pericardium. You will readily perceive that of these two classes of openings, those in which the matter escapes into cavities having no communication with the exterior are the most unfavourable. The confined pus excites violent and generally fatal inflammation, and we have a dangerous empyema, a rapid peritoneal inflammation, or intense pericarditis. I stated, that of the internal openings of an hepatic abscess, one of the most favourable is that in which the matter is discharged into the right lung, and I described briefly the mechanism of this curious process. We are warranted, I think, in declaring this to be a fortunate termination, because there are many instances on record of persons having recovered under such circumstances. A very near relative of mine presented an example of this. He was attacked with symptoms of acute hepatitis, for which he was attended by some of the most eminent physicians in Dublin. His treatment was bold and vigorous; he had free bleeding, both gene- ral and local, mercury, and every other means calculated to remove inflammation, but all proved ineffectual. His pulse became rapid; he began to sweat; the hepatic tumour increased in size, and pre- sented a distinct sense of fluctuation ; there could be no doubt of the existence of suppuration in the substance of the liver. One morning he was suddenly seized with a violent fit of coughing, and during the course of the day expectorated more than a large tea- cupful of pus ; towards evening this increased, and on examination it was found that the tumour was remarkably diminished. The expectoration continued during the whole night, and in the morn- ing it was observed that there was scarcely any appearance of the hepatic swelling. It was singular, and tends to confirm the idea that the matter had been discharged into the lung, that in the erect position this gentleman had scarcely any expectoration, but in the horizontal it was always extremely copious ; a circumstance which you can easily understand by considering, that in the recumbent posture the purulent matter would find a more easy passage into the lung. In this case, it would appear that the communication between the liver and lung was very free, for I remember that on one occasion by making pressure over the liver, he said I was forcing the matter into his chest, and the pressure was followed by an instantaneous and copious expectoration. This frequently occurred. A medical friend of mine residing in Dublin, mentioned to me some time since the case of a large robust drayman, addicted to whiskey drinking, whom he attended for an attack of acute hepatitis. At a time when the liver was very much increased in size, and well-marked symptoms of suppuration present, he ob- served that sudden expectoration of pus took place, which conti- HEPATIC ABSCESS. 133 nued for several days, with manifest subsidence of the hepatic tumour and complete recovery. Three cases of this kind came under my notice in the Meath Hospital. One of the patients had symptoms such as I have before described as exhibiting a striking similarity to yellow fever, from which he recovered, and was dis- charged, with no other remarkable symptom but quick pulse. Shortly afterwards he returned, complaining of pain in the right hypochondrium, with rapid pulse, profuse night sweats, and a slight cough. At first his appearance struck me as being characteristic of phthisis, and under this impression I repeatedly examined the chest by the stethoscope and percussion, but could not detect any lesion. The man had only a slight cough, and this was totally insufficient to account for his symptoms. The nature of the case was soon manifest: one morning the patient stated that he felt as if something had given way in his chest during the night, and he was from that time expectorating large quantities of purulent matter. On examining the lower portion of the left side, I found that it sounded completely dull on percussion, and that the physical signs of an accumulation of fluid in the bronchial tubes were extremely distinct. That this dulness was the result of the effusion in question is proved by the previously healthy state of the lung. The very day before I had carefully examined this part of the chest, and found it quite healthy. There was not the slightest resonance of voice in this portion after the accident, because the tubes were so completely filled ; so that in this case the return to health was accompanied by increase of broncophonia, a fact that sets the question of the nature of the accident at rest. It may appear strange that in this case the puriform matter entered the left lung instead of the right; but this is sometimes the case, particu- larly when the abscess forms in the left lobe of the liver. I shall now draw your attention to the particulars of a case which I look upon as almost unique, and which derives additional interest from the accuracy of the diagnosis. It is of great importance that you should have clear ideas on the subject of hepatic abscess, for, though the disease is not of common occurrence in this country, still, if called on to pronounce an opinion on a case of this kind, the least difference in the quantity of your information may be of consequence. The patient, who was the subject of this disease, was admitted into the wards of the Meath Hospital in August, 1828. The history of his case was, that he had been labouring, some time previously, under obscure symptoms of an hepatic affection, accom- panied by slight fever and jaundice, which had gradually subsided. Three weeks before admission he stated that he had irregular fits of shivering, followed by sweating, and when he came to the hospi- tal he complained of sickness of stomach, but particularly of cough and difficulty of breathing, which were extremely harassing, and said that he came in chiefly to be cured of his cough. He was considerably emaciated, and looked pale and low, but his stools had a natural appearance. On considering the history of his case and the symptoms then present, it struck me that it was either hepatitis 134 STOKES’S THEORY AND PRACTICE OF MEDICINE. with suppuration, or empyema of the right side with irritation of the liver. At that time I had not made my researches on the diag- nosis of empyema, and I must confess that I experienced a great deal of difficulty in determining the nature of the case. I found the right side considerably dilated, with dulness on percussion over its inferior half, but the intercostal spaces were not distended, and preserved their natural appearance. The case went on in this way for some time. Permit me to draw your attention for a mo- ment to this point. Dilatation of the right side may result from the pressure exercised upon it by a solid or by a fluid mass. If the mass be solid it will push the ribs outwards, but the intercostal spaces will still preserve their natural appearance. But if the protrusion of the side be the result of pressure by a fluid mass, the intercostal spaces will be acted on even more than the ribs, and the sulci, which mark their situation, will be effaced. Now, in this case the intercostal spaces were evident, and from this circumstance I determined that it was a liver disease. The patient continued for a fortnight without exhibiting signs of any material change, and then the tumour increased very much in size, but there was no ap- pearance of pointing. At this time the patient was visited and examined by a number of medical men, and all agreed that it was a case of deep-seated suppuration of the liver. Onder these cir- cumstances it was thought advisable to make an incision through the integuments down to the peritoneum, as recommended by Dr. Graves, and to keep the wound open by filling it with lint. This operation was performed, and the wound kept open for several days, but no matter came. On the sixth day the patient began to sink, his face became hippocratic, his extremities cold, and every one thought he was dying. During the course of the day it was observed that there was a circumscribed tumour, with a distinct sense of fluctuation, situated close to the wound, and towards the right side of the mesial line. Here is an important stage of the case ;—a man presenting evidence of suppuration in the liver has an operation performed on him to favour the exit of pus externally, and some time after this we find a circumscribed fluctuating tumour, nearly in the situation of the wound. We concluded that the hepa- tic abscess was pointing in that situation, and it was determined to pass a lancet cautiously into the tumour. This was done, but to our astonishment, instead of pus pure bile escaped through the incision. It was clear that we had mistaken a distended gall-bladder for an abscess, and this I need not tell you was a serious error. It is singular, however, that the accident was not followed by any bad consequences. About two hours after the operation the patient went to stool, and passed two large evacuations, consisting chiefly of a vast quantity of purulent matter. Next morning "he was surprisingly well, and the hepatic tumour had considerably di- minished. His countenance recovered its natural expression, his spirits were quite elated, his pulse had become tranquil, and the liver was manifestly returning to its ordinary dimensions. He began to sit up, was put upon generous diet, could walk about the HEPATIC ABSCESS. 135 ward, and was talking of leaving the hospital. From the period, however, at which the discharge of pus took place he had an obsti- nate diarrhoea, and though he took a great deal of nourishment he was still pale and emaciated. Twenty-two days after the subsi- dence of the tumour, another swelling began to make its appearance in the epigastrium, which increased daily, and it was obvious that another abscess was forming in the left lobe. About a fortnight after this he was suddenly seized with excruciating pain in the epi- gastrium, followed by symptoms of peritonitis. The tumour in the epigastrium subsided, but the patient sank in a few days of the peritoneal inflammation. Let me recall the circumstances of this case. First, we have obscure signs of the existence of abscess, then the sudden escape of matter from the bowels, accompanied with subsidence of the hepatic tumour ; in the next place a persistence of diarrhoea and emaciation, and, lastly, we have a new tumour in the epigastric region, disappearing on the supervention of symptoms of acute peritonitis. From a consideration of all these circum- stances I stated to the class that I should expect to find evidences of the abscess in the right lobe, which was the first affection, and I ventured to say, that the opening between it and the intestinal tube was still pervious. I was led to form this opinion from observing the persistence of the diarrhoea, to check which all the ordinary remedial means had failed. This was the first part of the diagnosis. In the next place I stated my belief that the gall-bladder had been punctured, but could not explain why the bile had not escaped into the peritoneum. Thirdly, I said that an abscess had formed in the left lobe, which had discharged its contents into the peritoneal cavity. All this was stated publicly, and on consideration you will find that there was no great difficulty in making the diagnosis. On dissection, we found a cavity in the right lobe with a small quantity of matter in it, and having a free communication with the duode- num. The fundus of the gall-bladder was found adhering to the parietal layer of the peritoneum, and the mark of a lancet wound in it was evident. A recent abscess was discovered in the substance of the left lobe of the liver, from which the matter had escaped into the peritoneum by a passage capable of admitting a small quill. Every part, therefore, of the diagnosis of this case was perfect, and borne out by the necroscopic appearances. You will see the details of this very interesting case in a paper published by Dr. Graves and myself, in the fifth volume of the Dublin Hospital Re- ports. This case is exceedingly interesting, because it illustrates two remarkable terminations of hepatic abscess: in one instance, by opening into a cavity which had an external communication, in the other, into a shut sac. The patient recovered from the first abscess, and would have done so effectually if the fistula had closed (no uncommon event); but he could scarcely have recovered from the second, because, where the matter escapes into the peritoneum or pleura, the patient almost invariably dies of acute inflammation of these cavities. This case derives additional interest from the 136 STOKES’S THEORY AND PRACTICE OF MEDICINE. circumstance of the gall-bladder having been opened. I believe this is the only case on record in which an opening made into the gall- bladder has not been followed by fatal consequences. I might detail many other cases of hepatic abscess, but I must at present refer you to the paper already alluded to, in which we have pub- lished the results of our experience on the subject. Some authors have mentioned gangrene, or mortification of the liver, as one of the modes in which acute hepatic inflammation may terminate. It is now however agreed, that this is one of the rarest terminations we can meet with ; in fact, that there is hardly any organic disease which so seldom occurs. Mr. Annesley states, that in all his dissections (and these were very numerous) he never met with a case of gangrene of the liver. Andral, who has exa- mined some thousands of bodies, has only met with a single case: this, with another which was under the care of Dr. Graves, and appears to have been a genuine example of mortification of the liver, are almost the only cases of which I have any distinct recol- lection. The case under Dr. Graves was that of a patient in Sir Patrick Dun’s Hospital, who laboured under chronic inflammation of the liver, with ascites, jaundice, swelling of the lower extremi- ties, and an incapability of lying on the left side. After this man had been about eleven days in the hospital he began to complain of tenderness and pain of the belly ; he was next seized with vomiting, and threw up a large quantity of fetid matter. Soon after this he sank, and, on dissection, numerous marks of chronic disease were found in various parts of the substance of the liver ; but in the left lobe there was a cavity which was distinctly gangrenous, and had in the centre of it a large mass of slough. I think that there can be no doubt that in this case the disease was actual gangrene of the liver. I think, too, it may be very fairly doubted whether gangrene of the liver is the result of inflammation, properly so called, in any case ; and I believe it would be a very interesting subject for enquiry, to consider how far this disease may be the result of hepatic apoplexy, or effusion of blood into the substance of the liver. This is an accident to which the liver, as well as every other parenchymatous organ, is subject; and though effu- sions of blood into its substance are by no means so common as similar occurrences in the brain and lungs, still it does not enjoy any thing like immunity from such lesions. We have good reason to believe, that in many cases blood effused into the substance of parenchymatous organs may, under certain circumstances, either undergo putrefactive decomposition and form a gangrenous abscess, or that, although no longer circulating in its vessels and effused into the parenchyma of an organ, it may still retain its vitality to a certain extent, and, being modified by the powers of life, may give rise to the formation of various morbid products. In this way it is thought that various tumours—cancerous, steatomatous, melanotic, and encephaloid—may originate. I am inclined to think that this sometimes occurs in the brain and lungs, and it is probable that it may happen in the case of the liver also. Further researches, HEPATIC ABSCESS. 137 however, are necessary, with respect to the elucidation of this mat- ter, before our opinions on it can possess a higher character than that of verisimilitude. While on the subject of hepatic abscess, it will be necessary to al- lude to one of its occasional complications—distended gall-bladder-— because this may be mistaken for the pointing of an abscess, and an operation be performed, and that this has happened more than once is a positive fact. A distended gall-bladder has been mistaken for the tumour formed by the pointing of an hepatic abscess, an opening has been made into it under this supposition, bile has escaped instead of pus, and this getting into the cavity of the peritoneum, has given rise to rapid and fatal peritonitis. A remarkable case of this kind has been detailed with great candour by the late Mr. Todd, in one of the early numbers of the Dublin Hospital Reports. He was called suddenly to visit a girl, whom on his arrival he found to be in a dying state, labouring under great distension of the belly, almost insensible, moaning constantly with her jaw fixed, and pre- senting a distinct tumour in the hypochondriac region, which, from the history of her case, he was Jed to consider as an hepatic abscess pointing externally. He divided the integuments and muscles down to the peritoneum, and having introduced a trochar, drew off nearly three pints of bile, with apparent relief. Shortly afterwards violent peritonitis came on and the patient sank rapidly. After death the liver was found to be healthy, and the tumour to have been formed by a distended gall-bladder of enormous size. From this, after the operation, the bile had escaped into the peritoneum, causing intense and universal peritonitis. In making a diagnosis in such a case as this, every thing will depend upon your know- ledge of the history and previous symptoms. The circumstances which produce distension of the gall-bladder, you will find upon examination do not bear any distinct resemblance to those which precede or accompany inflammation of the substance of the liver. We may have it from the obstruction caused by biliary calculi, and here you can make a tolerably sure diagnosis. We may have it from disease of the duodenum, or of the head of the pancreas, or* from the pressure of aneurismal tumours in the vicinity. Abscess of the liver is generally accompanied by symptoms of inflammation of that organ, but distension of the gall-bladder does not present any corresponding train of phenomena. There may be some exceptions to this rule, but in making the diagnosis we must strike a balance of probabilities. The first part of our diagnosis then is this—the occurrence of a tumour in the hypochondriac region, not preceded or accompanied by any of the symptoms which charac- terise hepatic inflammation. Another important diagnostic, and which I think will apply in several cases, is this. In a case where abscess was formed in the liver, the fluctuation, which is a sign of the existence of fluid, is often preceded by a condition of the part in which there is no sign of the presence of fluid; we have first induration and swelling, and then the signs of fluctuation; but this is not the order of succession in the phenomena which charac- 27 st. 10 138 STOKES’S THEORY AND PRACTICE OF MEDICINE. terise distension of the gall-bladder. In abscess we have a hard tumour which gradually softens ; in case of distended gall-bladder we have the tumour soft and fluctuating from the commencement. If, then, we have a tumour in the hypochondriac region, not pre- ceded or accompanied by symptoms of hepatic inflammation, ac- companied by jaundice, with a sense of fluctuation from the begin- ning, and unattended by hectic, the chances are indeed very great that it is not an hepatic abscess, but a distended gall-bladder. You will perhaps be surprised, that, in treating of the diagnosis of distended gall-bladder, 1 do not lay any particular stress upon position. The reason of this is, that the situations in which a dis- tended gall-bladder may be felt are extremely various. First, we may have it appearing in different parts of the hypochondrium, under the cartilages of the ribs. In the next place, we may have it between the cartilages of the ribs and the spine of the ileum. It has been observed by Andral in the iliac fossa, and he has seen it in the epigastric region. In a case which occurred in the Meath Hospital, it presented itself in the epigastrium, a little to the right of the mesial line. Again, in severe cases you may have the whole of the liver filled with bile, and having a distinct fluctuating feel, not produced by the existence of pus in that organ, but from the erdargement of its ducts, which are gorged with bile. In one case mentioned in the Medico-Chirurgical Transactions, this curious circumstance occurred. So far, then, as diagnosis is concerned, position appears to be of very little consequence; but when we have this, in addition to the other circumstances mentioned, it will tend to give additional certainty to our diagnosis. In all cases on record where there was distended gall-bladder, the patient laboured under jaundice, except in that which I have detailed in the early part of this lecture ; but perhaps if our patient had lived longer, he would also have had jaundice. There is one disease more which may be, and I believe has been, confounded with acute hepatitis and abscess of the liver. This affection, which has not been sufficiently noticed by authors, is in- flammation and abscess of the abdominal parietes over the hepatic region ; and this is a very singular disease. It is sometimes trifling, but I have seen a patient die of it. With the original nature of this disease I confess that I am not at all well acquainted; nor can I say whether the inflammation first attacks merely external parts, or whether it is a primary affection of the liver, and that the external parts take on diseased action from sympathetic irritation. In such cases we frequently observe many of the symptoms of inflammation of the liver, as pain, tenderness, biliary derangement, foul tongue, and morbid stools, with a tumefied state of the integuments. After these symptoms have continued for some time, the tumour increases in size, becomes softer, and matter forms. You give exit to the pus by opening the abscess with a lancet, and the patient gets well. This occurrence I have frequently witnessed. From a considera- tion of all the circumstances, it strikes me that in this disease the first morbid action in all probability commences in the liver itself, HEPATIC ABSCESS. 139 and that the external inflammation is an example of the strong sympathy which subsists between disease of deep-seated parts and integuments which cover them. Of this fact you have several illustrative instances. In pleuritis we frequently tind the integu- ments of the chest remarkably tender on pressure ; and in cases of inflammation of the brain the integuments of the scalp have their sensibility much increased. The same thing occurs in hepatitis ; and in this disease one of the first distinct symptoms is this tender- ness of the superincumbent skin. Now, you can conceive that, if this morbid sensibility of the investing parts should increase, in place of having some pain and tenderness, accompanied by swell- ing, we may have suppurative inflammation set up in these parts ; and that, under such circumstances, the inflammation may leave the internal organ where it first existed, and be thrown upon the external parts in its vicinity. It strikes me that this is not unfre- quently the case in this curious affection. In the case of this disease which I have seen prove fatal, the following circumstancs were observed :—evident symptoms of inflammatory fever ; pain and tenderness in the region of the liver, followed by the appearance of a tumour; which became fluctuating, was opened, and a quantity of matter discharged with considerable relief to the patient. She left the hospital, but returned again in about a fortnight or three weeks, with an enormous tumour in the same place, which was again opened, and a vast quantity of purulent matter evacuated. Though the matter continued to flow out freely, she did not recover strength ; and on enquiry it was found that before her second admission she had spit up some blood. One day, while dressing the abscess, the gentleman who attended her observed that when she coughed air passed out through the wound, proving the existence of a fistulous communication with the lung. On examination after death we found an abscess, the base of which rested upon the peritoneal sur- face of the liver, without engaging its substance. From this the matter had made for itself a double passage, one externally, the other through the diaphragm and pleura into the substance of the lung. This was the only case in which I have seen this disease prove fatal; and in it death appears to have been caused by the extent of the disease, and by the abscess opening into the pleura and lung. 140 STOKES’S THEORY AND PRACTICE OF MEDICINE.

You may remember, in one of my past lectures I alluded to a case of aneurism of the hepatic artery, of which I had procured a preparation: to-day I shall be able to exhibit to you the morbid appearances in this very remarkable case. It would appear that aneurism of the hepatic artery is an exceedingly rare circumstance. At a late meeting of the Academy of Medicine of Paris, a specimen of aneurism of the hepatic artery was presented to the society; and that celebrated pathologist, Cruveilhier, stated that it was the first of the kind he had ever seen. I wish to bring this preparation before you, not merely from the interest which its rarity excites, but also because the disease, in this instance, produced that distended condition of the gall-bladder to which I drew your attention on a former occasion, and which, in this case, was recognised before death. The gall-bladder formed a distinct pyriform tumour, situated a little above the iliac fossa, and the patient was deeply jaundiced. I shall state, from recollection, what I know of the details of this case. The patient was brought into the Meath Hospital, labouring under jaundice, which he stated to be of some days’ standing. He was thin and weak, and when questioned respecting his age, he said he was thirty-five, but he appeared to be upwards of fifty. His habits he described as being uniformly temperate and regular. Some years before he had suffered from an attack of apoplexy, but after this had enjoyed good health, until the occurrence of the present illness, which began with vomiting of blood, and which continued for some days and then yielded to medical treatment. He now experienced a loss of appetite, became quite dyspeptic and constipated; he also began to lose flesh, and under these circumstances applied at a dispensary, where he got various remedies without any benefit. Some time after this he observed, on getting up one morning, that his arms and legs looked rather yellow ; on the following day he had a decidedly bilious tinge with yellow vision, and in this state he entered the Meath Hospital. On admission he presented symptoms of general jaun- dice ; the urinary secretion was deeply coloured ; the skin, eyes, and nails yellow; the stools white and without any trace of bile. On examining the abdomen, the liver was apparently greatly in- creased in size ; in the epigastric region there was a tumour of considerable dimensions ; and in the iliac fossa we observed a separate pyriform tumour, which could be traced up to the edge of the enlarged liver. I mentioned at that time to the class, that there was something about the case which I could not understand. The disease was of inconsiderable standing; the patient had, a short time previously, been in a state of good health, and yet, reasoning ANEURISM OP THE HEPATIC ARTERY. 141 from analogy, this hepatic tumour could only have occurred as the result of chronic disease. It must have been the consequence of disease more or less chronic, and yet the history of the case was at variance with the idea of its chronicity. After some time the patient got miliary eruption, then petechial spots ; he continued in a low and weak state, and nothing did him any good. On the morning of the day of his death he did not appear worse than usual; he answered our enquiries respecting his health in his ordinary manner ; in the evening he sat up in bed gasping for breath, with a look of extreme distress ; he then leaned back on his pillow and expired. On opening the peritoneum we found a vast quantity of blood effused into its cavity, and my first impression was that it was aneurism of the abdominal aorta. On closer inspection, the aorta proved healthy, and the aneurismal tumour was found to be con- nected with the hepatic artery ; this had ruptured close to the gall- bladder, and its contents had been effused into the cavity of the peritoneum. We now found that the cause of the jaundice had been the pressure which this tumour had exercised on the biliary ducts. In consequence of the obstruction to the flow of bile, the ducts of the liver were dilated to an enormous extent; some of them were capable of admitting the largest sized finger. This dilation affected not only the larger trunks, but even extended to their most minute ramifications, even up to the surface of the liver; and here we found that the biliary tubes were dilated into sacs, some of which were as large as a hazel-nut. When these pouches were punctured the bile gushed out freely. A similar condition of the ducts has been noticed by Mr. Lloyd as existing in connection with obstruction of the biliary duct, from disease of the head of the pancreas, in his paper on Discharges of Fatty Matter from the Bow- els. (See Med. Chir. Trans.) I have got the preparation of this singular disease before me, and I regret that in one respect it is defective, inasmuch as it does not show satisfactorily the condition of the biliary ducts. A portion of the preparation which exhibits this appearance I gave to Dr. Houston, the curator of the Museum at the College of Surgeons, and I am sure that he will give ad- mission to any gentleman who is anxious to examine it. This preparation, gentlemen, is too large to send round. It exhibits the hepatic artery with its aneurismal tumour, and the opening by which the artery communicates with the aneurismal sac. Here is the place in which the rupture took place, and here is the gall- bladder greatly extended and thickened in its coats. Here, then, we have a new cause of jaundice, where the disease is the result of the pressure of an aneurismal tumour of the hepatic artery—a cause which has hitherto been unnoticed by writers on jaundice. The great interest of this case consists in this, that dis- section explained the difficulty which I felt in making the diagnosis at first, for it showed that the hepatic tumour was formed, not by an hypertrophied, but by a distended and displaced liver. It proved that it was formed, not by a process of chronic growth, but 142 STOKES’S THEORY AND PRACTICE OF MEDICINE. by the rapid formation of an aneurismal swelling and the conse- quent obstruction of the gall-bladder, accompanied by distension of the liver itself. With recent symptoms, then, we had, in this case, an enormously large liver, not the product of acute inflammation, but of distension of all the biliary ducts up to their most minute ramifications, and arising from mechanical obstruction. As far as it goes, this case appears to me to be perfectly unique. Let us turn now to the treatment of acute hepatitis. It is unne- cessary for me to say, that in all cases of acute visceral inflamma- tion, in the healthy subject, the first consideration is blood-letting, either general or local. In the early period of acute hepatitis, all authors have agreed in strongly recommending the use of the lancet; and there can be no doubt that when the disease is in its early stage, and the patient robust, the practitioner who omits employing these measures must be culpably negligent. It should always be borne in mind that the liver is an organ of paramount importance to life. There are two circumstances, also, which are in favour of bleeding in the case of an acute hepatitis—there is less chance of its being complicated with typhus fever, and general bleeding exercises a powerful influence over the acute inflamma- tions of parenchymatous organs. Hence we bleed with greater advantage in a case of acute hepatitis than in the inflammation of mucous membranes. Our first bleeding should be large, and such as will make a decided impression, and it will frequently be neces- sary to bleed a second and even a third time if the disease be very acute and the constitution strong, taking care to diminish the quantity at each successive bleeding, and to watch its effects. I have here to make one remark—that general bleeding is not the same heroic remedy, nor has it the same decided influence in ar- resting acute hepatic inflammation, as in checking pneumonia. A copious detraction of blood has, under favourable circumstances, often succeeded in completely removing an attack of pneumonia, and the patient has recovered without the employment of any other remedial measure ; but acute hepatitis is seldom or never cut short in this way. Still venesection is of the greatest importance ; and if it were performed merely with a view of preparing the patient for leeching and other depletive measures, its advantages would be unquestionable. I would recommend you, therefore, when you meet with a case of hepatitis in the early period, first to bleed freely, or in such a manner as to make a decided impression on the symptoms ; next, to empty the bowels by prescribing a pur- gative draught, assisted by an enema; and, lastly, to cover the region of the liver with leeches. You will find great advantage in employing your therapeutic means in this order ; for if you begin with leeches before you have had recourse to venesection, or the use of purgatives, your practice will not be so scientific, nor will your success be so complete. Bleeding, purgation, leeches, and the application of cupping glasses over the leech-bites (if necessary) will give you breathing time ; and, after the lapse of twelve or fourteen hours, you will find that all symptoms of urgent danger ANEURISM OF THE HEPATIC ARTERY. 143 will have passed away. During- the progress of the case, the remedy which I should principally rely upon is local bleeding, frequently repeated. If you apply thirty leeches to-day, I would not have you repeat them to the same amount to-morrow; but you might, perhaps, apply fifteen or eighteen, and the next day ten or twelve. By proceeding in this way you will find a great abate- ment in your patient’s symptoms; and I know of no circumstance which, taken singly, proves the value and benefit of your treat- ment so well as the diminution of the hepatic tumour, which you can acurately and satisfactorily ascertain by means of the pleximeter. When you find a gradual subsidence of swelling, I think you may be pretty sure that, even though the other symptoms exhibit little or no improvement, the hepatitis is on the decline, and will soon be removed entirely. You have all, I am convinced, heard a great deal of the use of mercury in hepatitis ; and there appears to be in the minds of most medical men a strong connection between mercury and all diseases of the liver. So far has this impression gone abroad, that to some practitioners it would appear perfectly heterodoxical to think of attempting to cure an hepatic inflammation without this accredited panacea. I must however confess that it is my belief that several cases of hepatic inflammation may be cured without it; and, if this be true, as I am convinced you will find by experience, it is so much the better for the patient. I do not mean to depreciate the value of this powerful remedy in making this assertion ;—it is undoubtedly a useful adjuvant, but it is only an adjuvant. It is decidedly second- ary and inferior to general and local antiphlogistics, followed by counter-irritation; and you should always bear in mind, that if you wish to bring about the full action of mercury on the system, you must precede its employment by means calculated to reduce the intensity of local inflammation. By premising general bleeding, leeching, and purgatives, you give the mercury an opportunity of exerting a decided influence on the salivary g-lands ; and in such cases it is that the most unequivocal advantage is derived from it; for, as I have observed in a former lecture, salivation appears often to be the result of the reduction of inflammation to a certain degree, and not its cause. In all cases of hepatitis occurring in delicate females, but parti- cularly in persons of low, scrofulous constitutions, endeavour to dispense with the use of mercury if possible. You will have con- siderable difficulty in divesting yourselves of early prejudices, and combating those of others ; but when you have an opportunity of acting for yourselves, I would have you make trial, and you will find that many cases are curable without mercury. If, after having regularly and carefully employed the means recommended, you perceive that two or three days pass without any improvement in your patient’s symptoms, and that the hepatic tumour remains undiminished, then indeed you may have recourse to mercury. But if you have been so fortunate as to have struck a decided blow in the commencement, and that the case is going on well, I would 144 STOKES’S THEORY AND PRACTICE OF MEDICINE. ask, why should you expose your patient to the misery and danger of salivation ? I am not by any means opposed to the employment of mercury in cases of liver disease; on the contrary, if we compare inflammation of the lungs, brain, and liver, with respect to the power which it has over each, I believe that it is much more appli- cable to cases of hepatic inflammation than it is to either pneumonia or cerebritis. There is nothing more common than a complication of disease of the liver with disease of the upper part of the digestive tube ; and here you will find that calomel will frequently cause great irrita- tion of the bowels, vomiting, and increase of fever. Under such circumstances, you must omit the internal use of mercury, and have recourse to frictions, directing your patient to rub in a dram of camphorated mercurial ointment every six or eight hours until the gums are affected. A very good auxiliary means is to place a dram of the mercurial ointment in the patient’s axilla, and leave it there; the action of the arm will, to a certain extent, answer all the purposes of friction. Dr. Graves is much attached to this mode. Where you have employed blisters, you may cut off the cuticle, and dress the raw surface with mercurial ointment. This also will contribute materially to produce the intended effect on the system. With respect to blisters, the same rules are to regulate their application as I have mentioned before, when speaking of the treatment of gastro-enteritis, namely—that they are not to be used until active antiphlogistic treatment has been employed; for it is then, and then only, that the stimulus of a blister can be useful. I believe it is seldom necessary, or even safe, to apply a blister before the third or fourth day in cases of acute inflammation of the liver. The physician who purges to-day, and blisters to-morrow, and bleeds next-day, is a very injudicious practitioner indeed ; he should bleed first, then purge ; and having by these means reduced the symp- toms of active inflammation, he may proceed to the use of blisters with advantage. It is unnecessary for me to remind you that you must enjoin a strict antiphlogistic diet in all cases of acute hepatitis. Recollect the powerful influence which all dietetic stimulants exercise, not only over the digestive canal and general system, but also over the liver; bearing this in mind, you will, for the first few days, keep your patient on a water and slop diet, and then on mild farinacious food and chicken-broth. But suppose that after all this, after having employed all the resources of the science and art of medicine, your patient becomes gradually weaker, his face pale and expressive of much constitu- tional suffering, his skin flaccid and bedewed with perspiration, his pulse small, rapid, and compressible; that the hepatic tumour increases in size, and when you throw aside his bed-clothes, the whole of the right side appears manifestly enlarged; and, if the bowels are empty, you see the hepatic tumour extending far down- wards into the abdomen; in addition to these symptoms, suppose the patient has had shivering fits, not only once but repeatedly; ANEURISM OF THE HEPATIC ARTERY. 145 that his perspirations are profuse, and have a sour smell; that his tongue is dry and glazed ; that his cheeks are hollow, and some- times present a circumscribed flush ; and that he is low, weak, and restless. Under these circumstances you may be sure that suppu- ration is commencing, or has been already established; and the question is, what are you to do? You must change your hand, you must give up antiphlogistics, you must omit the employment of all measures which have a tendency to reduce strength, you must prescribe a light nutritious diet, and anodynes to relieve irri- tation. When suppuration is fully established, the next considera- tion is, in what direction the contents of the abscess may escape; and here I need not remind you that it is much better that the abscess should open externally, through the integuments of the abdomen, or into some cavity having an external communication, rather than into a shut sac, as in the latter case it is almost certain, and often immediate death. At this period of the case it will be proper to support your patient’s strength by allowing him wine, increasing the quantity if the hectic symptoms threaten to run him down, and taking care that his diet be nutritious and of easy digestion. You will also take care to relieve his sufferings, and irritation attendant on the disease, by the judicious employment of opiates. When after some time the tumour becomes more elevated and distinct, the pain concentrated in one particular part of the liver, and the abscess is evidently pointing towards the surface, the ques- tion then is, whether we shall open it and give exit to the matter, and how this may be best accomplished. That the contents of the abscess should be evacuated as speedily as possible is true, but the consideration is, how far it can be done with safety. Now, I beg your attention to this point, as it has not been sufficiently attended to in works on the practice of medicine. Recollect what the ana- tomical condition of the parts is under such circumstances, and that, in order to get at the matter, you have to pass through a serous cavity. It. is obvious that if you make an incision into the tumour through the peritoneum, and if this be in a state of health, and without any adhesions between its layers in the situation of your incision, you run the risk of having the contents of the abscess effused into the peritoneal sac, and you know that this is almost of necessity fatal. The condition then for success is, the circum- stance of adhesion taking place so as to prevent the matter from getting into the peritoneum. Well, it seems to be a very simple thing to give exit to the matter of an hepatic abscess which presents a distinct pointing. Persons will say, adhesion has formed long since, the integuments are swollen and painful, the matter has crossed the peritoneum and lies close under the skin. Here, however, is a curious fact; of all the serous membranes in the body the peritoneum is that which is least liable to general or partial adhesions, and it is well known with respect to hepatitis with suppuration, that you may often have abscess so large as to form a distinct tumour on the surface, which 146 STOKES’S THEORY AND PRACTICE OF MEDICINE. shall be fluctuating, discoloured, and painful, and with all these conditions, so favourable to the notion of matter being actually under the skin, the patient dies, and on dissection we find not the slightest trace of adhesion. If you plunged a trochar or abscess- lancet into the tumour, what would be the consequence ?—death by peritonitis. Dr. Graves and I, in our report of the cases of hepatic abscess which occurred in the Meath Hospital, were the first who drew the attention of the profession to this interesting pathological fact, and, subsequently to this, Mr. Annesly, who has vast experience in hepatic abscess, stated that in his practice he found that the existence of adhesion between the layers of the peri- toneum in the vicinity of the abscess, even after swelling, tenderness, and discoloration of the integuments, is by no means a necessary consequence. It appears then to be quite certain, that the opening of an hepatic abscess is a matter of considerable nicety, and requiring a great deal of caution. The best mode of proceeding which can be adopted is, in my opinion, that which has been recommended by Dr. Graves, and which is founded on the most accurate pathological views. He makes an incision through the integuments, over the most promi- nent part of the tumour, and carries it through the cellular sub- stance, fat, and muscular tissue, until the peritoneum is nearly laid bare, and there he stops. The wound is then kept open by plug- ging it up with lint, and after some time the abscess bursts in this situation with perfect safety to the patient. This operation was performed under his direction, for the first time, in a case of abscess where there was no distinct pointing. It was the first operation of the kind, and every one who witnessed it waited with anxiety for the result. Five or six days passed away without any appearance of matter; but about this period the abscess began to point, shortly afterwards there was a large gush of matter through the wound, and the patient recovered perfectly in three weeks. Since that time the operation has been performed on two patients with success and safety. In the case of one patient it was performed twice at no very considerable interval. Now, I believe you are all aware that in cases of deep-seated collections of pus, it is of the greatest importance to remove the obstruction to its exit externally, and that matter will always point towards the place where there is the least resistance. The per- formance of this operation not only tends to remove the resistance, but also has this advantage, that the existence of irritation in the neighbourhood of the abscess, and immediately over the peritoneum, has a strong tendency to produce adhesion at this point; a circum- stance which I was able to verify in a fatal case, in which the abscess had pointed, but never burst. In this case we found on dissection six or seven small tumours near the surface of the liver, without any traces of adhesive inflammation in the peritoneum over them, but over the situation of the tumour, in the direction of which the incision had been made, there was a considerable quantity of organised lymph, and the two layers of the peritoneum were closely ANEURISM OF THE HEPATIC ARTERY. 147 adherent. That this effusion of lymph had not been accidental, is rendered probable by the rarity of its occurrence, from not being observed in other cases in which an operation had not been per- formed, and lastly from the success of the operation in those cases in which it had been employed. I would advise you, therefore, in all cases of hepatic abscess showing a tendency to, point, but parti- cularly if this pointing be distinctly towards the surface, to make an incision down to the peritoneum, fill up the wound with lint, and you will often succeed in causing the abscess to break externally, and without any danger to your patient. With respect to the bursting of an hepatic abscess into the cavity of the peritoneum, I have stated before to you, that it is almost necessarily fatal. I say almost, because I have seen two cases of this termination, of which one recovered completely from the peritonitis, and the other lived eight or nine days after the dis- charge of matter into the peritoneum, and on dissection it was found that a process of cure had been going on. The first of these cases was that of a young woman who had a vast chronic abscess. An attempt was made to make this open externally, by destroying the soft parts over it with caustic, but this not succeeding, a lancet was introduced through the eschar made by the caustic. The patient was immediately afterwards attacked with severe pain in the abdomen, and distinct symptoms of peritonitis. As she was very weak and emaciated, Dr. Graves, under whose care she was, gave her opium in full and repeated doses, allowing her the free use of wine and porter; no blood was drawn, no depleting measures of any kind used, but every thing done to support strength and relieve irritation. Under these circumstances (won- derful to relate) she recovered from the peritonitis. She after- wards sunk from the abscess, and on dissection we found that the peritoneal cavity was obliterated, just as the serous investment of the testicle has its opposed surfaces glued together after an ope- ration for the radical cure of hydrocele. In the other case, the patient lived eight or nine days after the occurrence of symptoms of peritoneal inflammation. On dissection, we found a large quantity of transparent lymph effused on the surface of the perito- neum, in the substance of which several large blood-vessels had been developed. The principles of treatment in a case of this dreadful accident is to support strength and remove irritation, laying aside all antiphlo- gistics. I am sure that, under such circumstances, the ordinary modes of treating peritonitis are inapplicable and useless. As I shall return to this subject when I come to speak of peritonitis, I shall here merely state, that the treatment of such a case as this is to be conducted upon the same principles as peritonitis, produced by rup- ture of the intestine, or a perforating ulcer. Gentlemen, I shall occupy your time briefly in treating of chronic hepatitis. You will find a full description of the symptoms of this disease in almost every book on the practice of medicine, and it is unnecessary for me to detain you with details of this 148 STOKES’S THEORY AND PRACTICE OP MEDICINE. kind. If we are to judge from British practice, chronic hepatitis is a very common disease, and, if we look to the practice, it is an affec- tion under which half the community labour. I believe, indeed, that the chronic form of this disease is much more frequently observed in this country than the acute, but still I think it is any thing but a disease of universal prevalence. I shall not, as I said before, take up your time in stating what you will find in any medical work ; I shall merely mention that in chronic hepatitis we have generally derangement of the bowels, chiefly affecting the stomach and upper part of the digestive tube, and in addition to this we have more or less pain, tenderness, and swelling in the region of the liver, and often dulness of sound over the lower part of the right side. When we meet with this train of phenomena, we say that the patient has the symptoms of chronic hepatitis. But no one under such circumstances could undertake to say whether the patient will die of hypertrophy or atrophy, of cancer or hydatids, of tubercles, or of fatty discharge, or of any peculiar disease of the liver. There is another point, too, of which I am anxious you should be aware. Chronic hepatitis is a disease which has been, and is, frequently confounded with various other affections ;—with scirrhus of the pylorus, with chronic disease of the duodenum, with chronic disease of the pleura, and empyema of the right side. There is one circumstance which you should bear in mind when you are in doubt with respect to a chronic hepatitis, that one, two, or three of these affections may occur in connection with chronic inflammation of the liver. For instance, a patient labouring under chronic hepatitis may have also at the same time empyema and disease of the duodenum. I believe the subject of disease produced, as it is said, by contiguity in separate organs, has not as yet been sufficiently investigated, and that our knowledge on this important point is extremely scanty. There are two circumstances connected with this part of the subject, on which I shall say a few words. One common error is that of confounding affections of the heart with those of the liver, and this I regret to say is an error of very serious consequence, and one which is frequently observed in tbe consultations of medical practitioners. A patient complains of palpitations, a physician is called in, and pronounces the disease to be hypertrophy of the heart; another is called in, and gives it as his opinion that the liver is affected ; a third is summoned, and says that both the liver and heart are diseased. In such cases you should always make a careful examination, and weigh well the circumstances of the case in your mind before you venture to pronounce an opinion. In the first place, you are to recollect that organic disease of the heart may produce disease of the liver. Secondly, that disease of the liver (though not so often) frequently brings on morbid affections of the heart and nervous palpitations. Thirdly, that these affections act to one another reciprocally as cause and effect. If a person has disease of the heart, the current of the circulation through that organ is obstructed, and you may have disease of the liver, not as 149 ANEURISM OF THE HEPATIC ARTERY. the result of any original affection of that organ, but as the effect of chronic obstruction to the passage of blood through the heart. The consequent congestion and disease of the liver may, in such a case, be reflected on the digestive tube, and this in turn may re-act on the heart. The heart sympathises then with the irritation of the digestive tube; we have nervous palpitations, and if these continue for a length of time, we have the disease of the heart increased. Again, suppose a patient has chronic disease of the liver, causing more or less obstruction to the circulation ; the heart begins to sympathise, palpitations commence, go on increasing, and finally terminate in hypertrophy of the heart. The mischief does not stop here; the effects of obstruction extend to the vena cava hepatica, this in turn re-acts on the liver, and we have in this way a curious train of phenomena; first liver disease, then heart disease, and lastly liver disease again. Let me once more impress upon you that, under such circumstances, you cannot be too diligent in making an examination, or too cautious in pronouncing an opinion. There is another thing connected with hepatic disease which you should be aware of. A patient, labouring under the following train of symptoms, comes to consult you;—he has pain in the right hypochondrium, loss of appetite, deranged bowels, morbid stools, a dirty bilious hue of countenance, and, in fact, all the symptoms of diseased liver. You examine the liver and find it very much tumefied, in fact, its size is so much increased that you would at once be inclined to say that it was extensively diseased. Now, there are some cases of great tumefaction of the liver accompanied with more or less of the symptoms of hepatic derangement, and yet in such cases you may have no disease of the liver at all, at least none of the ordinary forms of hepatitis: these are cases in which there exists, in adults, a persistence of the embryonary condition of the liver. If we compare the condition of this organ in the infant and in the adult, we find many essential points of difference. In the infant it is comparatively large, and, as it were, hypertro- phied ; it descends far below the margin of the ribs, and occupies a large portion of the abdominal cavity. On the other hand, if we examine its state in the adult, we find that it has shrunk beneath the short ribs, and that its size and dimensions are com- paratively much reduced. Now this physiological atrophy of the liver is a natural and healthy process. There are certain individuals, however, in whom\ this change does not take 'place, and who grow up with the liver bearing the same proportion to the other organs as it did in the foetal condition. This curious condition is one of the varieties of arrest of development, and is, in almost every instance, observed in those persons whose constitu- tions present that train of phenomena to which the term scrofula has been applied, and which (if I have time) I shall show you is explained, or at least great light is thrown upon it, by the theory of arrest of development. In such subjects the tumefaction of the liver is by no means a measure of actually existing disease. If 150 STOKES’S THEORY AND PRACTICE OF MEDICINE. you were to suppose this tumefaction of the liver to be the product of actual recent disease, and proceed to treat the patient in the same way as you would treat a case of hepatitis in the healthy subject, you would not only do no good, but, in ail probability, a great deal of mischief. I know the case of a gentleman, in the enjoyment of good health, who has this tumefaction of the liver to a very great degree. He is of a thin spare habit of body, with a full, round* and prominent belly; he is pursuing the avocations of an active profession, and yet you will hardly credit me when I say that his liver extends below the umbilicus, and close to the anterior superior spine of the ileum; yet he is very active, and to all appearance a healthy man. You will often meet with this condition of the liver in children who are attacked at an early age with symptoms of tabes mesenterica. At the next lecture I hope I shall be able to finish diseases of the liver, and proceed to the consideration of other affections of the system. LECTURE XVIII. Treatment of chronic hepatitis—Neuralgia of the liver succeeding hepatitis—Connect tion of hepatic with gastro-intestinal disease—Modes of transmission of disease from the mucous surface of the liver—Phlebitis of the vena porta—Obstruction of this vein—Case of pulmonary, hepatic, and intestinal fistulre—Hepatic neuralgia. We now come to the consideration of the treatment of chronic hepatitis. It is of great importance, in a case of this kind, to place your patient under such circumstances as will ensure the full and favourable action of the remedies employed. The use of wine, spirits, and all kinds of exciting food, must be laid aside; the patient must not use any thing capable of producing fever during the process of digestion. So long as any kind of food or drink pro- duces uneasiness and sensations of heat and fulness, you may be sure that it will do more harm than good. Give him what will support his strength without exciting the vascular or nervous systems during the process of digestion. You must next prevail on your patient to give up the use of active purgatives by the mouth. This is a point which you should strongly and firmly insist upon, as, in consequence of the ordinary costive state of the bowels which accompanies chronic inflammation of the liver, the patient is generally in the habit of having recourse to those temporary and hurtful remedies. It is the same thing in cases of chronic hepatitis as it is in chronic gastritis; you will find the subjects of these diseases taking different purgatives every day. Break your patient of this practice, if possible ; you will have some difficulty in doing so, for he has been long habituated to it, and you must exercise all your authority in putting a stop to the pernicious habit. Instead of purgatives by the mouth, make him use every TREATMENT OF CHRONIC HEPATITIS. 151 day an emollient injection. You may, if necessary, give, occasion- ally, mild laxatives by the mouth, as Rocvhelle salts, manna, castor oil, or something equally mild, and in this way you will be able to secure a regular alvine discharge, once in the twenty-four hours at least. But where there is considerable pain and tenderness in the region of the liver, this plan alone will not be sufficient; you must apply relays of leeches, a practice which has a most admirable effect in chronic hepatitis. I would advise you to apply cupping- glasses over the leech bites ; by doing this, you get as much blood as you wish, and you will generally save your patient from the annoyance of an oozing hemorrhage. When piles exist, it will be useful to apply leeches to the anus, followed by the hip bath. But I have no hesitation in saying, that, as a general mode of reliev- ing hepatic disease, the application of leeches to the right hypochon- drium is far preferable in every point of view. You may, in the next place, have recourse to blisters; and I have frequently employed blisters, alternately with leeches, with the best results. Tartar emetic ointment, in the form which I have already mentioned, croton oil frictions, and other modes of counter-irritation, will assist materially in bringing about a successful termination. But these must be continued long, and used over an extensive surface. In this way, by regulating your patient’s diet, keeping his bowels open by enemata, or the mildest laxatives, by small and repeated local bleedings, with counter-irritation, you will frequently succeed in removing all the symptoms of chronic hepatitis without the use of mercury. But if, after having carefully employed all these measures, the symptoms manifest a degree of persistence, if your patient has not already taken a large quantity of mercury (which is not likely to be the case in this country), and if he be not of a scrofulous habit, I see no reason why you should not have recourse to mild doses of mercury. For this purpose, nothing answers better than to prescribe, once or twice a day, a pill composed of hydrarg. c. creta, blue pill, or a small quantity of calomel, combined with rhubarb, extract of hyosciamus, and taraxacum. It will be seldom necessary to bring on actual salivation ; but if the pain continues to be severe, the swelling undiminished, the symptoms obstinate, and no contra-indication existing, you may bring him under the influ- ence of mercury, and keep him so for a short time. The best mode of doing this is to direct him to rub in a dram of the cam- phorated mercurial ointment every day ; and if you have employed blisters, you can assist the frictions by dressing the blistered surface with mercurial ointment. Some practitioners are in the habit of substituting the nit.ro- muriatic acid for the mercurial treatment, and there appears to be evidence that it is an advantageous mode of practice in these cases. The best mode of using this remedy seems to be the endermic ; and, hence, bathing the feet, or sponging the right hypochondrium with the acid, are most recommended in chronic affections of the liver. As it is convenient to have a formula for making the nitro-muriatic solution, I shall give you the following. Take of strong nitric and 152 STOKES’S THEORY AND PRACTICE OF MEDICINE. muriatic acids of each four ounces, and add to these eight ounces of pure water. Here you have a sixteen ounce mixture ; of this com- bination you may take from two to five ounces, and mix them with three gallons of warm water. This, I believe, is the form recom- mended by Mr. Annesly. Having placed this solution in a foot bath, or tub, you should direct your patient to keep his feet in it for twenty minutes or half an hour. If the bath be of proper strength, it will communicate to the skin a prickling sensation ; if not, you may increase its strength by adding an ounce or two more of your mixture. The same solution will answer for sponging over the liver. There is no doubt that, in certain cases of chronic hepatitis, this remedy has been found decidedly useful, and as its employment is unattended with any dangerous or disagreeable consequences, it has strong claims to our notice. The cases of chronic hepatitis to which it seems to be peculiarly adapted, are, first, those where mercury has been used irregularly, or for a long time without any benefit, and, secondly, where the patient is of a broken down con- stitution, and where you are anxious to dispense with the use of mercury, if possible. Here the intro-muriatic treatment is of decided value. I need scarcely remark to you that this acid fre- quently acts upon the system somewhat like mercury, producing tenderness of the gums and ptyalism. Such an effect as this, fur- nishes us with an example of these cases, in which we find other remedies, as well as mercury, producing a decided effect on the salivary glands, and exercising a very powerful influence over hepatic and syphilitic affections. An interesting fact, bearing on this point, is related by Mr. Cox, in his account of his residence on the Columbia river. Several of his party, who used a strong decoc- tion of the fresh sarsaparilla, were salivated. There is one circumstance, connected with the treatment of chronic hepatitis, which I believe has not been sufficiently dwelt on. You may have a case in which there was distinct evidence of chronic inflammation, and where, under the influence of judicious treatment, the signs of inflammation and organic derangements sub- sided, but where severe pain still continues to be felt in the region of the liver. The nature of this pain is often mistaken; it is sup- posed to depend upon a continuance of inflammation, while it is, in reality, nothing more than a mere neuralgic affection—a rem- nant or successor of the former disease, to which the antiphlogis- tic treatment is totally inapplicable. Under such circumstances, the patient goes from one practitioner to another, takipg different medicines, and submitting to repetitions of the usual modes of treat- ment, but with little or no benefit. Now I have seen, in several cases, this symptom yield completely to treatment calculated to remove purely neuralgic affections. In a case, lately under my care, of a gentleman who had been attacked with enteritis and hepatitis in India, and who had taken enormous doses of calomel “for the liver,” and of croton oil “for the bowels,” this circumstance occurred. When first I saw him, he was emaciated, the skin 153 TREATMENT OF CHRONIC HEPATITIS. yellow, the urine high-coloured, with thirst, costive bowels, and great tumefaction in the region of the liver. These symptoms completely subsided under treatment, but a violent pain, running at intervals, continued obstinate. This was rapidly removed by a course of the carbonate of iron, and the use of the belladonna plaster. It is of great importance, in the treatment of chronic hepatitis, to bear in mind the state of the gastro-intestinal mucous membrane. You are aware that the disciples of Broussais are of opinion that almost all cases of hepatic inflammation are secondary to a gastro- enteritis ; that the first morbid action is on the surface of the intes- tinal tube, and that it is transmitted from this to the liver. I have taken a considerable share of pains in investigating this subject, and have examined very carefully the question as to the complication of hepatic inflammation with disease of the gastro-intestinal surface, and the conclusions to which I have come, are the following:—In the first place, that most cases, whether of acute or chronic inflam- mation of the liver, present the complication, more or less, with dis- ease of the intestinal mucous surface, and that in the majority of instances there is some degree of actual disease of the digestive tube. It would appear, also, from observation of different cases of hepatitis, that in a great many the affection of the liver has been secondary, and that symptoms of disease of the digestive tube have preceded those of hepatic irritation. But, on the other hand, we must admit that the hepatic affection may be primary; that the liver has the irritative, and that disease has been subsequently propagated to the gastro-intestinal mucous surface. Lastly, we may have hepatitis, both acute and chronic, quite independent of any disease of the mucous coat of the stomach and bowels. This, I believe, is the rarest case; still it does occur. You observe, there- fore, that the doctrine of the physiological school, that all hepatic inflammations are secondary to a gastro-enteritis, is not supported by the authority of facts. It is therefore wrong to say that every case of acute or chronic hepatitis is preceded by gastro-intestinal inflammation. Facts have been brought forward to show that not only has inflammation of the liver been observed in the simple state, and independent of any complication with intestinal disease, but that the affection of the liver has distinctly preceded the symp- toms of gastro-enteric disease. On the other hand, however, I am free to admit that these are the exceptions rather than the rule, and that, in the majority of cases, hepatitis is either secondary or com- plicated with disease of the gastro-intestinal surface. Now, a very interesting question comes to be considered, and this is, how does the disease come from the gastro-intestinal surface to the liver ? Pathology informs us that irritation may be trans- mitted from one organ to another in three different modes. First, sympathetically, as through the medium of the nerves. Thus, long-continued stimulation of the stomach is reflected upon the liver, the liver sympathises with the suffering organ in its vicinity, and finally becomes diseased itself. It is in this way that many st. 11 154 STOKES’S THEORY AND PRACTICE OF MEDICINE. chronic affections of the liver and stomach terminate in affections of the neighbouring viscera and dropsy. The first mode, then, in which disease may come to affect the liver from the gastrointes- tinal surface, is by sympathetic irritation. The next mode is sup- posed to be the actual transmission of disease along the biliary duct from the duodenum to the liver. Inflammation commences in the duodenum; this creeps along the ducts until it reaches the liver, which takes on the inflammatory action in its turn. Several persons of high authority have supported this view of the question, and assert that they can actually demonstrate the passage of inflamma- tion along the ducts. Without denying the possibility of this, yet I feel convinced that it is rare. I have never been able to discover this mode of propagation of inflammation from the duodenum to the liver; and it must be remembered that, in the great majority of cases of duodenitis, we cannot detect inflammation in the liver or its appendages. The last mode by which disease may be trans- mitted, is the propagation of inflammation along the course of the veins belonging to the portal system, that is to say, there is phlebitis of the portal system, and the inflammation travels along the veins until it arrives at and attacks the liver. That this has occurred, is proved. But we may suppose that, in certain cases, disease of the liver may result from a phlebitis of the minute mesenteric veins, without a continuous spread of inflammation to the larger trunks ; just as the lung is affected in cases of phlebitis of the extremities, not by actual spread of inflammation, but rather, as Mr. Arnott has shown, by the transmission of the products of that inflammation. Inflammation of the portal veins is a circumstance which possesses great interest in a pathological and practical point of view ; it is a curious process, and there are some singularities connected with it which have a claim on our attention. In the Clinique Medicale of Andral, there is a ease given of a patient who, after labouring for some time under symptoms of fever and gastro-enteritis, was attacked with pain and tension in the region of the liver, followed by jaundice. On dissection, marks of inflammation were found in the stomach and ileum; there was also some disease in the colon, and the liver was found to be enlarged, and presenting the ordinary marks of inflammatory action. On a more minute examination, nearly all the mesenteric veins, and the trunk of the porta, were discovered to be in a state of intense inflammation; while, on the other hand, the lining membrane of the vena cava was found to be in its normal and healthy condition. Here we have a very remark- able coincidence between disease of the liver and of the portal system. First, the patient had fever, with gastro-enteric inflamma- tion, and then pain and tension in the region of the liver, followed by jaundice. On dissection, the mesenteric veins and the trunk of the porta are found inflamed; this condition extends to the liver, the substance of which is found tumefied, red, and friable. I believe there can be no doubt that disease of the liver may be brought on by dis- ease of the abdominal veins, particularly those of the portal system. It is a very curious fact, that with symptoms such as many prac- TREATMENT OF CHRONIC HEPATITIS. 155 titioners would not hesitate to call chronic hepatitis, we may have phlebitis, terminating in obliteration of the porta, and even of the vena cava. In such cases, nature generally makes an effort to keep up the venous circulation ; in consequence of the obliteration of the internal abdominal veins, the external ones become enlarged, and produce a supplementary circulation to a certain extent, and in this way life is prolonged. This drawing, which represents the appear- ance of a patient labouring under this form of disease, will give you some idea of the matter. You observe the patient’s belly is enlarged and prominent, his extremities cedematous ; and here you see those enormous veins passing along the surface of the belly, and keeping up a collateral venous circulation. In the patient, from whom this drawing was taken, the porta and cava were obliterated. These are the epigastric and other superficial abdominal veins which ascend to anastomose with the thoracic, intercostal, and axillary veins. I shall now relate, as briefly as possible, the particulars of this very remarkable case. The patient, who was the subject of it, laboured for more than twelve months under jaundice, accompanied by wasting of flesh and prostration of strength, but for the first eight months he had not been confined to bed. He suffered, how- ever, very considerably even at this period, from constant pain in the epigastrium and swelling of his feet. Now, in this country, we would be very apt, under such circumstances, to say that he was labouring under chronic hepatitis. At the end of the eight months he became bed-ridden, and the large veins, which you here see, began to make their appearance. Although he was wasting in flesh, still he had a canine appetite, and was always complaining that he had not enough to eat. This is an interesting fact. It has been observed in other cases, and tends to throw some light on the share the mesenteric and other abdominal veins have in the process of absorption. In tabes mesenterica it has been often remarked, that the little patients have generally enormous appetites ; and, as it would appear from the same cause, a deficiency of nutritious absorption, with this difference merely, that in the disease before us it is the veins that are diseased, whereas in tabes mesenterica it is supposed to be the lymphatics. But to return to our case. This patient had, as I remarked, a very voracious appetite, by indulging which, he brought on repeated attacks of constipation and colic. He then got diarrhoea and dropsy, for which he was tapped twice without any benefit. From observing that there was in this case an extraordinary supplemental circulation, leading to the inference that there was obstruction of the deep-seated veins ; from remem- bering that the appearance of the patient, and the more prominent symptoms, coincided with those of a former case, in which oblitera- tion of the porta had been discovered after death; from these cir- cumstances, and the remarkable voracious appetite, M. Reynaud, under whose care the patient was, came to the diagnosis of phlebitis of the portal system, extending to and affecting the liver ; and this diagnosis was subsequently confirmed by dissection. He was, 156 STOKES’S THEORY AND PRACTICE OF MEDICINE. however, unable before death to explain one symptom which was present, namely, infiltration of the lower extremities. You are aware, that when the general venous circulation is obstructed either in the chest or belly, we have anasarca of the lower extremities, but when the obstruction affects only the portal system, then we have ascites as the first phenomenon. If you had two cases of dropsical effusion, in one of which there was, first, oedema of the lower extremities, in the other, first, ascites, you could thus determine where the primary obstruction existed. M. Reynaud was at a loss to account for this symptom in the present case, as he had not observed it before in the other case, and as the swelling of the feet had preceded that of the belly. On dissection, it was found that the right branch of the porta had been obliterated by the growth of a yellow substance, somewhat like the middle coat of arteries ; the same was found to exist in the corresponding hepatic veins, and the inferior cava was found obliterated to the distance of three inches from the left auricle. The left branch of the porta was per- vious, the corresponding hepatic veins much enlarged, and the superficial epigastric veins inosculated freely with the intercostal and axillary veins. The vena azygos was very much dilated ; and, what is extremely curious, a large vein was seen to arise from the union of the sub- peritoneal branches on the convex surface of the liver; this passed through the diaphragm, and emptied itself into the cava close to its termination. Here we have an entirely new vein. It was also observed, that the sub-diaphragmatic veins were much increased in size, and apparently varicose; these passed through the diaphragm, and inosculated with the pericardial and superficial thoracic veins. Some of them ran up and opened into the great coronary vein of the heart, which was as large as the crural vein. The remaining peculiarities of this curious case were inflammation of the duodenum and gall-bladder. The cavity of the latter was half filled with purulent fluid. I am fully convinced that I have seen instances of this disease, although I was not so fortunate as to have an opportunity of verify- ing the diagnosis by dissection. I have seen patients who had wasting of flesh, pain and tension in the region of the liver, and jaundice, with this singularly varicose state of the external abdo- minal veins ; some of them had ascites ; and I recollect distinctly, that in one case the appetite was very great, and the patient had a tendency to diarrhoea. I am satisfied that in such cases you would be fully justified in making the diagnosis of obstruction of the portal system; and if, in addition, there was infiltration of the lower extremities, there would be a probability that the disease had extended to the cava itself. Before I proceed to the consideration of a subject to which I have already alluded—hepatic neuralgia—it may not be amiss to exhibit some specimens of organic lesions of the liver. Here is an example of abscess of the liver:—you perceive the softened yellow degenera- tion of the substance of the organ; and here is the cavity of the 157 abscess, in which you may observe a loose slough suspended. This portion which surrounds the abscess may be looked upon as a fair specimen of the yellow softening of the liver, before its substance breaks down into a purulent mass. Here is another specimen exhibiting the same phenomena. Here is a very curious example of hepatic abscess, which perforated the diaphragm, and made its way into the substance of the lung. I regret that the whole of this preparation has not been preserved. The rest of the preparations before me illustrate chronic disease of the liver. Here is an example of the disease which has been called cancer of the liver. Time will not permit me to enter into a detail of the pathological circumstances of this case. The patient was a female, who had cancer of the breast, scirrhus of the pylorus, and aneurism of the aorta, with this disease disseminated through the substance of the liver. Here is another preparation of what would be called by many persons pure cancer; the patient, a female, had cancer of the mamma. This, and the preparation on the other side, exhibiting a mass of white, firm, semi-cartilaginous substances, are examples of what has been called tubercle of the liver. Here is an example of the disease which has been termed whiskey liver, a disease which is said to be ordinarily found in persons who indulge in the use of ardent spirits. This, however, is a term which has been often abused and misapplied; for persons indulging in the use of whiskey may have every form of disease of the liver, and the appearance before you may be detected in the livers of persons of the most temperate habits. On the label of this preparation is written—“A Specimen of Whiskey Liver,” but this you will not mind. There is a very remarkable fact, however, respecting this kind of liver, verified by Professor Carswell, namely, that this condition of the liver is always accompanied with more or less ascites. I may add, that I have never met with this disease without ascites. I remember a most remarkable case of disease of the liver, which occurred during my stay in Edinburgh. My lamented friend and instructor, the late Dr. William Cullen, whose loss to pathological medicine was irreparable, and whose splendid attainments and high character justly and rapidly raised him to an elevated rank in his profession, brought me to see a patient. One of the most curious circumstances connected with this case was, that when the patient sat up in bed, a fluid of a serous character was poured out in con- siderable quantity from the anus; but while he remained in the horizontal posture this did not occur. The patient died shortly afterwards; and, on dissection, it was found that he had a gan- grenous abscess of the right lung, communicating with the pleural cavity, which contained a quantity of a sero-purulent fluid, and a mass of hydatids, some broken down, others perfect and entire. On continuing the dissection, it was found that the cavity of the pleura communicated with the right lobe of the liver through the diaphragm. In the right lobe of the liver the same kind of sero-purulent fluid, and a quantity of hydatids, were discovered; and, what was still more extraordinary, the cavity in the liver was found to communi- TREATMENT OF CHRONIC HEPATITIS. 158 STOKES’S THEORY AND PRACTICE OF MEDICINE. cate with the colon by a distinct opening. There was, then, in this very remarkable case, a direct communication between the bronchial tubes and the colon, through the pleura and liver. We can thus see that, when the patient assumed the erect position, the fluid would immediately pour into the colon. As I am anxious to finish the subject of hepatic disease to-day, I shall now draw your attention to one of the last points connected with this subject, namely—neuralgia of the liver. It is a singular fact that a patient may labour under severe and harassing pain in the region of the liver; that this pain may last for months and years; that he may die of some other affection ; and that, on examination after death, we may find the liver without the slightest trace of disorganisation; and, also, that the organs in its vicinity present no appearance of any organic disease. Many cases of this kind have been observed; and it is the opinion of the best patholo- gists that they are examples of neuralgia, the seat, of pain being the hepatic plexus. Jt is a disease of no very unusual occurrence, and is often found in females of a nervous and hysteric habit. It is constantly mistaken for hepatitis, and there is no greater mistake than this, or one which is likely to entail more misery on the patient. The persons who are subject to this affection are, as I remarked before, generally of a nervous and hysteric habit; they complain of pain in the right side, of more or less constant occur- rence, and this pain, during its exacerbations, is often most excru- ciating. Now, this circumstance furnishes us with a sort of key to diagnosis ; for with this dreadful pain, and, in some cases, exquisite tenderness in the region of the liver, we have the skin cool, the pulse tranquil, no fever, no permanent derangement of the bowels, no tumefaction of the liver. If this were the pain of acute inflam- matory disease, a fatal result would be produced ; or if it belonged to a chronic affection, it would terminate in organic derangement; and yet we find it existing with a clear colour of the skin and eye, healthy faeces, calm pulse, and absence of swelling in the region of the liver. Add to this, that the disease may have lasted for a con- siderable time, and that it occurs in a person of hysteric and nervous habit. Moreover, if the patient has been treated for hepa- titis unsuccessfully, you may make up your mind to the diagnosis of hepatic neuralgia. Here is the diagnosis ; pain in the region of the liver, with occassional violent exacerbations, and accompanied by tenderness of the integuments, but without swelling, symptoms of fever, or abdominal derangement; the disease being of long standing in a person of nervous habit, and having resisted bleeding, mercury, and even counter-irritation, or being made worse by those measures. Now, it is no uncommon thing to see this disease mistaken for acute hepatitis; and I need not tell you how ruinous to the patient’s health such an error must be. When you are in practice, you will meet instances of females labouring under this affection, who have gone through a variety of treatment. When you recollect that the disease occurs generally in hysteric females, and that such persons TREATMENT OP CHRONIC HEPATITIS. 159 are injured by depletion, you can conceive how much mischief may be done by repeated bleedings and courses of mercury. Some of the most deplorable cases I have witnessed, were those in which neuralgia of the liver had been mistaken for hepatic inflammation, by a number of practitioners, and the patient subjected to such modes of treatment as gave her constitution a shock from which it never recovered. The treatment of this disease must be both general and local, but by no means what you would call antiphlogistic. You will have some difficulty in preventing the patient from getting herself blooded ; for though the lancet is inadmissible, yet its employment gives a temporary relief, and this encourages the patient to have recourse to it again. What I would advise you to do in this disease is, first to pay attention to the general condition of the patient. You must pursue a general anti-hysterical plan of treatment, remove every source of irritation and excitement, and take measures to improve the general health by exercise, regimen, moral improve- ment, and the judicious employment of tonic medicines. With respect to the pain, one of the most powerfld means of arresting and removing it, appears to be the use of the carbonate of iron in full doses; and this is an interesting circumstance, when we recol- lect the power which it possesses in removing pain in other nervous diseases. I would advise you to try this after having pre- mised the use of purgatives, and continue it for some time, for you will often find that it will not only cure the pain, but also improve your patient’s strength and appetite. While you are giving it, order your patient to take some mild purgative, as compound rhubarb pill, to prevent constipation. When you are about to pre- scribe a course of carbonate of iron, you should prepare your patient to find the stools coloured. I have known this circumstance taken hold of and turned to their own advantage by quacks. The patient is told that his complaints arise from the existence of morbid and dark-coloured matters in his bowels. Preparations of iron are given, and the black matter begins to come away, greatly to the credit of the empiric. After a time, the medicine is omitted, and some purgative substituted ; the stools become natural, and the trick is complete. During the paroxysms of pain, a mustard plaster, or anodyne stupes, and anodyne enemata, will give relief; and, in the intervals, I would advise you to use the belladonna plaster, after the following formula:—Take of extract of belladonna three parts, of gum ammoniac and soap plaster each one part; spread these on a piece of leather with an adhesive margin, and make the patient wear it over the region of the liver. If there be any tenderness over the lower dorsal vetebrse, you may apply a few leeches, followed by narcotic stupes, or counter-irritation. I have seen this hepatic neuralgia without any hysteric compli- cation. I remember the case of a lady who had three or four healthy children, and had never been subject to hysteria. This lady came up to Dublin to be treated for liver disease—in fact, to be salivated; but happening to fall into the hands of a judicious 160 STOKES’S THEORY AND PRACTICE OF MEDICINE. friend of mine, who recognised the true nature of her complaint, she was treated with carbonate of iron, and cured effectually. I knew another case of a young gentleman, in whom (after being treated for symptoms of chronic hepatitis) this pain continued for a considerable time, and was at length removed by carbonate of iron, and the use of the belladonna plaster. LECTURE XIX. Gastritis, with delirium tremens—Varieties of intestinal worms—Organisation and origin of—Occurrence in the foetuses of various animals—Formation—Pathology of —Perforation of the intestines by—Worms in tumours and abscesses. You may recollect that, when treating of acute gastritis, I alluded to the great importance of being aware of its complication with delirium tremens ; and stated, that in the form of delirium tremens, which is the result of an excessive debauch, and where the stomach has been subjected to powerful stimulation, we have reason to believe that there is more or less of gastric inflammation. I have it in my power, to-day, to exhibit to you a very accurate drawing of the stomach of a patient who laboured under this form of disease, and whom I had an opportunity of examining several times before death. You will remember, also, I mentioned that in cases where symptoms of delirium tremens had arisen from excess, and not from a want of the customary stimulus, the ordinary routine treatment of giving wine, brandy, and other spirits, was extremely improper ; and that where it was persevered in, and the patient died, you commonly found, on dissection, evident marks of inflammation in the brain and stomach. On that occasion, too, I quoted this as an example of the latency of gastric symptoms when complicated with an affection of the nervous centre. I have now to exhibit this drawing, which represents the stomach of a man who died of deli- rium tremens, supervening on a severe debauch. This patient was treated entirely on the stimulant plan ; he got wine, porter, brandy, and opium, but their exhibition was not attended with the slightest benefit. Under their use his symptoms changed, and assumed a decided cerebral character; he had hot skin, quick pulse, great thirst, and general symptoms of fever, accompanied by a comatose condition. Previously to opening the body, I gave it as my opinion that the stomach would be found to exhibit marks of inflammation. Here is an accurate drawing of the stomach, and, from its appear- ance, you will be able to judge for yourselves. (Here Dr. Stokes exhibited the drawing to the class, representing the stomach in a state of intense vascularity.) Observe the generally diffused dark red colour of the whole organ, and the excess of inflammation towards its cardiac orifice. The brain, in this case, was but slightly vascular. INTESTINAL WORMS. 161 I propose to devote this day’s lecture to the consideration of an interesting subject in practical medicine—intestinal worms. There are few subjects possessing so much interest, in a physiological and pathological point of view, as this; and, in order to have correct notions, it will be necessary for you to be acquainted with the investigations of modern science on this subject. You are well aware that worms are found in most classes of animals. They occur in reptiles, fishes, birds, in the different classes of quadrupeds, and in man. In man they do not exist in such abundance, nor so frequently, as they do in birds and fishes. With respect to their places of habitation, we find them, first, in cavities which have an external communication, and next, in the parenchymatous sub- stance of organs; and we generally observe, that those which inhabit the cavities are different from those met with in paren- chymatous parts. We observe, also, that the species existing in the different organs and cavities are not only different in their nature, but that there is a difference between the worms which inhabit separate portions of the same organ or cavity. In one part of a cavity or organ we find one species, in another a different, and this occurs almost invariably, as if it was regulated by a fixed law of the economy. A peculiar species of worm, occurring in man, called the distoma hepaticum, is never found except in the li ver or gall-bladder. If this animal had been introduced from without, it would certainly be detected in some part of the intestinal canal, but this is never the case. Rudolphi states, that the strongylus horridus is to be met with only in the oesophagus of aquatic birds, and the ascaris obtusa in the stomach.of mice. Generally speaking, worms are of three different forms—cylin- drical, riband-shaped, and vesicular. Their organisation varies from the lowest scale, in which we can scarcely trace, as it were, the rudiments of an animal; beginning with the tape-worm, which presents little more than a cellulo-gelatinous mass, we ascend gradually until we arrive at a high degree of organisation, where we find well-developed muscles, a difference of sex, generative organs, and, according to some anatomists, a tolerably perfect nervous system. Now, to remove all sources of doubt and error on this interesting subject, and to establish proper principles of treatment, let us examine into the origin of these animals. I shall confine myself to the consideration of the origin of those worms which inhabit the human intestines, as they are the only species which we have to do with as practical physicians. You will at once perceive that worms must be derived from one of two sources ; either as introduced from without, or formed originally within the bodies of man and other animals. It is main- tained by those who are in favour of the first supposition, namely, that they are introduced from without, that similar animals are to be found in the external world, and that they are introduced either in the form of ova, or in a state of perfect development, with the food or drink, or by the respiration of the animal. Observe, this 162 STOKES’S THEORY AND PRACTJCE OF MEDICINE. doctrine is founded on the validity of the assertion as to whether animals similar to intestinal worms are to be met with in external nature. Linnaeus states, that he found the tape-worm, and the small ascarides, a species now called oxyuris vermicular is, in a marsh in Lapland; but Muller, a much more accurate helmintho- logist, has since shown, most satisfactorily, that Linnaeus was com- pletely mistaken, and that those he had observed are never found to exist within any animal whatever. There are many observa- tions on record similar to those of Linnaeus ; but as they were made at a time when natural history was in its infancy, and as they have been disproved by the researches of modern zoologists, I shall not notice them. I believe there is no well-authenticated instance on record of tape-worms, lumbrici, or ascarides, being found living in any situation external to the animal body. Every one of you have seen worms in the intestinal canal, or recently discharged by stool or vomiting ; but I will venture to say that not one has ever observed them in any article of food, in earth, or in water. Bremser, who is a high authority, makes a very pertinent remark on this subject. “We find,” says he, “all animals most abundant in that situation which has been assigned to them by nature. Now, if these animals were accidentally introduced from without, we ought to find them more abundant in the earth, water, &c.; but the contrary we have seen to be the fact.” But it is contended that these animals may have been introduced from without, and that in consequence of a change in situation, nutriment, and other circumstances, their forms may be altered; and it is argued, in support of this hypothesis, that external cir- cumstances will and have been observed to change the forms of plants and animals in a very remarkable degree. In addition to this, it may be said that an alteration in the nature of its food may even produce an actual change in the function of the animal. It is a singular fact that neuter bees may be made prolific by chang- ing their food ; it is shown that when a queen bee dies or is lost, the neuter bees take a grub of their own species in place of her, and, by feeding it in a particular manner, it becomes capable of laying eggs. Now, supposing that intestinal worms are introduced in the form of ova into the human body, there is no reason why this sudden, remarkable, and complete change should take place. We see nothing similar to it in nature. The plant which springs from any particular seed will resemble that from which it derives its origin; the egg of any particular bird, no matter in what way it may be hatched, will produce an organised being similar to its parent. The form and character of the animal are given during the act of generation, and remain unchanged. Again, admitting that a difference in circumstances and nutrition might produce a total change in form, it should be in our power to demonstrate the individual in the process of transition; we should find those animals in a state half between what they were and what they are, and this state we should observe of very frequent occurrence. No such thing, however, has been ever demonstrated. Out of a vast INTESTINAL WORMS. 163 number, Bremser did not find a single one in any stage of trans- ition, nor has it been demonstrated by any zoologist. He also states expressly, that after having diligently examined fifteen thou- sand specimens of worms in the cabinet at Vienna, he never was for one moment at a loss to say which were intestinal worms and which were not. If there was any such transition, it would have been discovered, but no such thing has ever been observed. It appears, then, obvious that there is no direct evidence to prove that these animals have been introduced into the body from with- out, either in the form of ova, or in a state of perfect development. We have nothing, then, I think, but to come to the other conclu- sion, that they originate within the body, and this seems to be the opinion of the best physiologists and pathologists. This doctrine appears to be almost brought to a demonstration by the following facts. First, it appears that the worms which have been found in man and animals have a peculiar structure and organisation, differ- ing materially from that of the worms which inhabit the external world. This is a point admitted by almost every modern writer on natural history. In the next place, we find that the worms of certain animals present peculiarities differing from those of the same species in others. Thus the bothriocephalus and taenia solium, in man, differ from those of other animals. You are not, however, to conclude from this that every animal has its peculiar worms, for such is not the case. Thus the lumbricus and small ascarides of man are found to exist in various animals, both carnivorous and graminivorous. It appears obvious, that if worms were introduced from without, we should not find peculiar worms in the bodies of certain animals; yet taking a certain number of different animals, living on the same food and in the same situation, we find a difference in the nature of the worms which are met with in the bodies of each. Another important fact is, that worms are to be found not only in the intes- tinal canal, but in almost every part of the body. We find them in the cellular tissue, in the liver, gall-bladder, lungs, and trachea; in the brain, heart, kidneys, and spleen. They have been met with in the air-bladders of fishes ; and Treutter states that he has found the polystoma pinguicola in the ovaries of a woman which were steatomatous, and the strongylus in an aneurism of the mesen- teric artery of the horse. These animals have been observed in the anterior chamber of the eye in birds and horses, and there are innumerable examples of their occurrence in situations equally strange and anomalous. Another circumstance already mentioned, and which must be coupled with the fact just alluded to, is that there are certain species of worms which occur only in the same organs, and are never met with in any other situation. Now, observe the importance of these facts—we find that worms not only exist in the digestive tube, and parts having an external communication, but also in the very substance of deep-seated viscera, and that the worms which are found in the various cavities and organs are peculiar to them. In one case, we find a worm in 164 STOKES’S THEORY AND PRACTICE OF MEDICINE. the digesti ve tube, in another in the brain, in a third in the liver, in a fourth in the pulmonary apparatus, but no one has ever been able to demonstrate the trajet of a worm from one of these cavities or organs to another. It would be ideal and absurd to say, in the case of worms found in the substance of viscera, that they had been introduced from without, or came from the intestinal canal. The distoma hepaticus, which is found in the liver and gall-bladder, might be supposed to arrive at those situations by passing along the ductus communis choledochus; but in the various cases in which it has been found, it has never been detected in the intestinal canal; and this, I think, would not have been the case, if the digestive tube had been its original situation. One of the most important facts which have been stated is, that certain forms of these animals are found invariably in certain situations; and this has been observed not only in man, and other animals of the class mammalia, but also in reptiles and fishes. In man, we generally find the lumbricus inhabiting the stomach and small intestine, the tricocephalus in the caecum, and the small oxyuris, or thread-worm, in the rectum. The preparation before me exhibits a specimen of the rarest form of worms which inhabit the intestinal canal, the tricocephalus. Here is the caecum filled with these singular worms. The males are distinguished from the females by the whirl of the tail. If these little animals, or the oxyuris, had been introduced from without, we should expect to find them in various parts of the intestinal canal ; but we find, on the contrary, that their situa- tion is separate and distinct. Lastly, intestinal worms have been found in the foetus, both of man and other animals. Kerkring describes a foetus, the intes- tinal canal of which contained a vast quantity of small worms; and another of six months, in whose stomach a large lumbricus was found. Rudolphi, Blumenbach, and others of nearly equal autho- rity, have recorded abundance of examples of worms existing in the foetuses of various quadrupeds, and also in those of birds which had just broken the shell. Those who are obstinately attached to the doctrine that worms are introduced from without, have gone so far as to assert, that the ova of the worms have been transmitted at the moment of generation, a doctrine so absurd that it is unneces- sary for me to enter into any refutation of it. With respect, then, to the formation of worms in animals, we cannot help coming to the conclusion that they are originally formed within the body, and that, in fact, there is an original gene- ration of these animals, the result of one organisation taking place within another—the production, in fact, of a distinct being. This idea does not appear so difficult of conception when you recollect that circumstances analogous to it are extremely familiar and of almost constant occurrence. There is not much more difficulty in conceiving the formation of a living worm within the body than there is of conceiving the organisation of a portion of lymph thrown out upon the surface of a serous membrane. What occurs in both cases is, that, under the influence of the vital principle of the original INTESTINAL WORMS. 165 animal, a portion of matter, previously inorganic, assumes the pro- perties of life, presents distinct traces of organisation, vascularity, and sensibility. The only difference between them is, that in one case the organised mass remains adherent to the matrix, and in the other it is cast off, and forms a separate being. In the present state of our knowledge, all speculation on the mechanism of the formation of worms must of necessity be nothing more than mere hypothesis. The idea which Bremser entertained on this subject is, that intestinal worms are formed by the presence of semi-assimi- lated nutritious matter in the digestive tube. Food, taken into the system under ordinary circumstances, is converted into a substance fitted for the purposes of absorption and nutrition; but when the process is not perfected, it is not taken up by the absorbents, and is then, according to Bremser, converted into an animal substance. This appears to be but a crude idea, unsupported by any facts ; and it would be more philosophical to say that we know nothing about the matter. Besides, worms occur in various parts of the body as well as the digestive tube ; and to suppose the presence of unassimi- lated matter in such situations would be only supposing an absurdity. Bremser brings forward, in support of his theory, that worms are of very frequent occurrence in cases where the assimi- lating powers are weak or deranged, and says that nothing is more common than to meet with an abundance of these animals in scrofulous persons, in those who have great appetites and bad diges- tion, and in children labouring under disease of the mesenteric glands. On the other hand, there are abundant instances of worms existing without the slightest apparent injury to the general health. In certain countries almost all the inhabitants have worms. But I believe all that we can affirm on this subject is this, that they are not introduced from without, and that they are formed within the body by a process, the nature of which is exceedingly obscure. Now, to come to the pathology of this subject, can we connect the formation of intestinal worms with any known pathological condition of the intestinal canal? This is a question of no ordinary importance ; for if we were able to connect their formation with an inflammatory or any other state of the digestive tube, it would furnish us with a key to correct and successful treatment. The school of Broussais are of opinion that worms are the result of an acute or chronic inflammation of the gastro-intestinal surface. This doctrine is by no means supported by the evidence of facts, for it has been established that worms are found to exist not only in connection with every possible pathological condition of the intestinal canal, but also where the tube presented the appearance of perfect health. We cannot, then, safely affirm that intestinal worms are connected with an inflammatory or non-inflammatory condition of the digestive tube. Andral states that he has found them in all conditions of the intestine, whether red or pale, dry or covered with mucus. They are most commonly, he says, enveloped in a quantity of mucus, and there is some redness in the place where they are lodged; but this appears to be rather the effect of 166 STOKES’S THEORY AND PRACTICE OF MEDICINE. their presence than the cause. I believe it to be the fact, that persons in excellent health, and with the intestinal canal in the normal state, may have worms. Dogs, who are killed while in a state of apparently perfect health, are often found to have a large quantity of tape-worm in their intestines. It is idle and hypothetic to say, that the formation of worms depends upon an inflammatory or non-inflammatory, an asthenic or sthenic condition of the digestive tube; their formation is owing to some modification of the vital power, the nature of which is unknown. I again repeat, that nothing can be stronger against the supposition that worms depend upon inflammation than the fact of their being observed in consi-- derable quantities in healthy individuals. A very curious point, connected with this subject, is the question of perforation of the intestines by worms. This question, which is an interesting one in many points of view, has been lately the sub- ject of medico-legal discussion, and therefore demands a share of our attention. Of the different kinds of intestinal worms, the only one which is supposed to be capable of perforating the coats of the digestive tube, and escaping into the peritoneum, or some adjoining organ, is the lumbricus, which is remarkable for its vigour, and for the sharp and pointed shape of its head and tail. Many of the most eminent pathologists of modern times, and, among the rest, Andral, Rudolphi, and Carswell, are of opinion that these worms are totally incapable of perforating the intestinal tunics. Andral states that there is no well-authenticated instance of this occurrence on record; and Rudolphi declares that they have no apparatus for effecting a passage through any continuous tissue. On the other side of the question, however, there are some curious facts and cases given, which, supposing that worms are incapable of perfo- rating, are very difficult to explain. Dr. Fischer, of Vienna, gives the case of a female, in whom the following circumstances were observed on dissection. Two circular orifices were found in the colon, communicating with the cavity of the peritoneum; in one of these openings a worm was discovered, one half of which lay in the peritoneal sac, the other in the intestine. No other worms were found in the digestive tube; but a second worm, like the former, was found in the peritoneum. Here we have a very remarkable coincidence of perforation of a portion of the gut, with the existence of one worm in the cavity of the peritoneum, and another of a similar description, as it would appear, in the act of making its way in the same direction. These circumstances, together with the existence of a double perforation, seem to be in favour of the idea that the openings had been made by the corre- sponding worms. Another case is mentioned in the Elements of Pathological Anatomy, by Andral, and he quotes the case, not as one of perforation merely, but to show that the symptoms of effu- sion of matter into the peritoneum may, under certain circum- stances, be nearly latent. The subject of this case, a young man, labouring under phthisis, had a tumour near the umbilicus, which increased rapidly in size and presented a distinct fluctuation. INTESTINAL WORMS. 167 Soon afterwards, the integuments grave way, and a large quantity of matter was discharged, together with a lumbricus. During the progress of this disease, there was some tympanitis, but little or no pain had been complained of. On dissection, there was a consider- able number of worms, and a quantity of matter, found in the peri- toneum, and a perforation in the arch of the colon, corresponding with the extravasated matter. Bremser gives a curious instance of this kind, as occurring in a species of fish. In this case, the fish died ; and it would appear, says Bremser, that the worm, finding some extraordinary change had taken place, was determined to take a peep and see what was the matter, for it had perforated not only the intestinal tube, but actually made a passage for itself through the whole body of the fish, until it reached the water in which it had been lying. Here, finding that its world extended no further, it stopped, and began to make its way back again to its original situation by a new opening, so that when it was observed by Bremser, the two ends were in the intestinal tube of the fish, and the middle portion external. This, however, does not resolve the question, as to whether lumbrici are capable of perforating the intestinal canal or not. My own impression on the subject is, that we have not, as yet, any distinct and unquestionable evidence of these worms being possessed of any perforating power ; but it is a fact, that there are a great many cases on record of worms being discharged in considerable quantities from openings in the intestinal tube, and where it would appear that the openings had been formed, not so much by the action of the worms themselves, as in con- sequence of their exciting an irritation in some portion of the intestine, followed by inflammation, ulceration, and escape of the contents of the tube into the peritoneum. There are many in- stances of this kiud. An interesting case is mentioned of a female, who was attacked with pain in the groin, followed by the appear- ance of a tumour, which she was directed to poultice by her medi- cal attendant. After some time, the integuments gave way, a quantity of matter was discharged, followed by a large lumbricus, and during the progress of the case about one hundred of these animals were discharged through the opening. This is a well- authenticated case. Another case is mentioned of a patient who had been subject to constipation and violent attacks of colic. A tumour began to appear in the right hypochondrium, followed by pointing and ulceration of the integuments, and a discharge of matter. A number of worms (I believe twenty-four) were dis- charged through the opening, which remained pervious, and the patient lived for many years afterwards with an artificial anus. This case appears to be not an example of direct perforation from worms, but of the accumulation of a mass of these animals in a particular portion of the intestine, giving rise to irritation, which terminates in ulcerative absorption of its tunics, and escape of its contents. Inflammation is set up in some part of the intestine, this goes on until the coats are all destroyed, and the matter and worms escape into the peritoneal cavity; but if adhesion should prevent 168 STOKES’S THEORY AND PRACTICE OF MEDICINE. this, an opening will be formed in some part of the integuments covering the belly. In both cases, the opening is produced not by an exertion of the worms, but by an ulcerative and vital process. In support of this view, it has been observed that worms have come out through these apertures not head foremost; the centre portion appears first, and you can draw it out like a loop. Such cases as the foregoing, then, cannot be fairly given as cases of perforation from worms, but as cases in which these animals, acting somewhat like foreign bodies, produced irritation, inflammation, and ulcerative absorption. There is a very curious case on record, of a patient labouring under abscess of the liver, which burst externally, and a lumbricus was discharged with the matter. The patient died; and, on dissection, it was found that the cavity of the abscess had a communication with the stomach, through which it was conceived that the lumbricus had got into the liver. The worms which inhabit the intestinal canal in man are the following:—first, the lumbricus, or common round worm; next, we have the tape-worm, of which two varieties have been described; thirdly, we have the very curious worm, of which there is a speci- men before me—it inhabits the caecum, and is called tricocephalus; lastly, we have the thread-worm, to which the name of oxyuris vermicularis has been lately given. The lumbricus generally inhabits some portion of the small intestine, but is also frequently found in the stomach. Persons have often vomited them, and they have been known to have crept out by the mouth. They have been found also in the pharynx, oesophagus, and large intestine. There is an interesting case mentioned by Andral, of a child who, in a state of apparently good health, was suddenly seized with symptoms of suffocation, and died. On dissection, it was found that a large lumbricus, which had come up from the stomach, had, when it arrived at the glottis, turned into its orifice, and, by irritat- ing the larynx, produced spasmodic closure of that organ, and suf- focation. The lumbricus presents very marked appearances of an advanced state of development. The male has a peculiarly formed penis; the female has her generative organs well developed; and both have an extensive alimentary canal. The tricocephalus is about an inch in length, terminating in a point; the sexes are different, and the male is distinguished from the female by the circular whirl of his tail—it is always found in the caecum. The small thread- worms, with which you are all acquainted, are almost exclusively found in the rectum. These worms are found in vast numbers in some children ; and it is said that the quantities of them which are discharged by the West Indian negroes are extraordinary. The tenia, or tape-worm, is generally found in the small intes- tine ; but it has also been observed in the stomach, colon, and rectum. The length to which this animal sometimes attains is almost incredible. Bremser mentions a case in which a tape-worm one hundred and fifty feet in length was discharged by stool Another case is given, in which the tenia had the enormous length SYMPTOMS OF INTESTINAL WORMS. 169 of three hundred feet. I have myself seen a large wash-hand basin filled by a mass of tape-worm, discharged after a strong dose of castor oil and turpentine. Still more extraordinary instances are recorded. Thus, in the Copenhagen Transactions, we read of a tape-worm eight hundred ells in length. But, in all probability, there has been an error in these measurements, and many worms have been taken for one. This is rendered probable by the fact observed by Robinus, who found in the body of a man, who had before death discharged fragments of tape-worm, a tape-worm extending from the pylorus to within six inches of the anus. The length of this single worm was scarcely thirty feet. One interesting circumstance connected with this animal is, that it is inferior in its organisation to every other species of worm. It appears to be nearly a simple, homogeneous, cellulo-gelatinous mass, without any division of sexes, and without a nervous system, or generative organs. It is said, also, to occur principally in persons whose powers of life are low; and if this be the case, as I believe it is in many instances, it furnishes us with a very curious and interesting fact. The other better developed kinds are found in persons of healthy, good constitutions; but the tape-worms, though sometimes met with in such persons, are generally found to occur in persons of low and weak diathesis. Here we see a curious connection between the product and the producing cause. With respect to the exciting causes of worms, a vast number of circumstances have been mentioned by authors, as giving rise to their formation. Foul air, low, damp situations, bad diet, the con- stant use of milk, cheese, sugar, vegetables, have been reckoned among their exciting causes. I believe we are not well acquainted with these causes. They appear often to be connected with some morbid influence produced upon the system by bad diet, and other circumstances; but what the nature of this influence is, we know not. LECTURE XX.

Let us proceed with the consideration of intestinal worms. At my last lecture you will recollect that I spoke of the different kinds of worms, and stated that there was a difference between the worms which are found in various parts of the body; that I examined the question as to the origin of these animals, and came to the conclu- sion that they are formed originally within the bodies of man and 170 STOKES’S THEORY AND PRACTICE OF MEDICINE. other animals. I mentioned the various kinds of worms which inhabit the digestive tube in man, and examined at some length the question of perforation of the intestinal canal by lumbrici. We come now to the investigation of the symptoms. With respect to the symptoms of worms, it is a singular fact, that we have not one single pathognomic sign of their existence, except the circumstance of their being occasionally passed by stool, or vomited; almost all their symptoms are referable to irrita- tion of the gastro-intestinal surface, and its sympathetic relations. Persons, who are much subject to worms in these countries, are generally of a pale complexion, with a bluish circle round the eyes; the belly is more or less prominent, and there are various signs of irritation of the digestive tube, with itching at the nose and anus; headache; foul breath and tongue; irregular and some- times canine appetite, nausea, hiccup, borborygmi, tenesmus, diar- rhoea, and constipation. Though the patients take abundance of nutriment, they are generally thin and pale; and in such cases there is either one or two very large worms, or a great number of smaller ones, or their presence is complicated with disease of the intestinal canal. Such persons are also observed to be of an indo- lent and languid habit; they have perspirations, disturbed sleep, with grinding of the teeth, and irregularity of pulse. The sympathetic irritations produced by worms are numerous and extraordinary. The genital organs may be excited, and we may have priapism and seminal emissions in the male, and irrita- tion amounting to nymphomania in the female. There is a very singular case on record of a female, aged seventy, being seized with a violent attack of nymphomania from this cause. The nervous affections produced by worms are so Protean and so numerous, that it would be almost impossible to detail them; in fact, there is not a single nervous disorder which may not be simu- lated by the sympathetic irritation of worms. Epilepsy, hysteria, convulsions, dilatation of the pupil, amaurosis, symptoms of hydro- cephalus, and even mania, are among the affections of the nerv- ous centres or their immediate connections, which, in repeated instances, have been found to depend on the presence of worms. Kraus gives an extraordinary case of a man, who, at a very advanced age, became subject from this cause to fits of continued and inordinate laughter. There is another case on record of convulsions depending on worms, which, like those from the bite of the tarantula, are said to have been soothed and relieved by music. Hufeland, in his journal, mentions a case of yellow vision from the same cause; and there are several instances of aphonia and mania on record, which have yielded to treatment which had removed intestinal worms. A case is mentioned of a person who got violent spasmo- dic action of the muscles of the eye, producing inversion of that organ to such a degree that the eyeball appeared to be nothing more than a mass of red flesh. A case is recorded by Serres, in which the symptoms strongly resemble those of hydrophobia; and SYMPTOMS OF INTESTINAL WORMS. 171 it is probable that some of the cases of hydrophobia, said to have been treated successfully, were nothing more than this extraordi- nary irritation of the nervous system produced by worms. I saw, myself, a case in which two eminent physicians made the diagnosis of hydrocephalus; it was that of a child, who was certainly, to all appearance, labouring under cerebral disease—for he had convul- sions, coma, and dilated pupils. It was remarkable, however, in this case, that the treatment directed to the head, though early and well applied, proved totally inefficacious. A large dose of calomel was given, and some lumbrici passed; in the space of two or three hours there was an evident improvement, and the child quickly recovered. During the course of practice I have met with several examples of affections of the respiratory organs, depending upon the irrita- tion of worms. This affection has been long known. I recollect the case of a boy who was brought to me with an extraordinary affection of the chest. He was of a gross habit of body, of a flabby scrofulous appearance, and labouring under disease of the elbow- joint ; but his chief complaint was, that he passed the night in great distress from incessant cough and wheezing. On examining the chest, I found the respiration healthy, and no other symptom of pulmonary derangement except a very slight bronchitic rale. On expressing my opinion of the case to the mother, she said that he was easy during the day, but that his condition was very differ- ent at night. To ascertain the truth, I took the child into the hospital, and found that her statement was substantially correct ; for, from four o’clock in the afternoon until next morning, he was in a state of perfect orthopncea, with loud, ringing, incessant cough. During the rest of the day he was free from cough, and tolerably quiet. The case was treated with calomel and ipecacuanha, tartar emetic, and other similar remedies, but the disease was rather exas- perated than improved. The boy had swelled belly and constipa- tion, and for this he was ordered to take a dose of turpentine and castor oil. He passed some worms with relief to the existing symptoms; and from the consideration of this, and the failure of the treatment for bronchitis, we were determined to persevere in the use of anthelmintic medicines, and for this purpose put the child on syrup of couhage, to be followed by castor oil draughts. He passed vast quantities of thread worms in the course of a few days, and when they had been all removed the cough disappeared altogether; but, as long as any of them remained, the symptoms of pulmonary irritation continued. There could be no doubt that this was a case of intermittent bronchial irritation from worms, for their evacuation was immediately followed by a complete cessation of cough and dyspnoea. I have also, since the foregoing, met with many other instances of a similar description. A young girl came into the Meath Hospital with chronic bronchitis, and some degree of hepatisation at the lower part of the left lung. Having heard from her friends that she was extremely subject to worms, I deter- mined to try what would result from the use of anthelmintic 172 STOKES’S THEORY AND PRACTICE OF MEDICINE. medicines, and put her on the syrup of couhage with aloetic pills. Under this treatment the cough was quickly removed, and the lower portion of the lung recovered its permeability. Here it was remarkable, that not only irritation of the bronchial mucous mem- brane, but even solidification of the lung, were cured by treatment calculated to remove worms. Mr. Ramsay, in his paper published in the Medico-Chirurgical Transactions, gives several cases of haemoptysis from this cause. 1 think I have seen several cases of phthisis, where the original source of pulmonary irritation seemed to be the existence of intestinal worms. Let me here, however, remind you that we should be cautious in attributing too much to worms as the causes of morbid symp- toms. There are several reasons why you should be on your guard in this respect, one of the most obvious of which is this: it does not follow, in the first place, that the symptoms in any particular case are produced by worms; because the same cause, which may have predisposed to the formation of worms, may have produced the symptoms in question, and there may be merely a coincidence of worms and of these symptoms. Even if we look to the results of treatment, there is a great deal of doubt and difficulty. There are many cases on record which are described as cases of epilepsy from worms, and where all the symptoms have subsided under the use of anthelmintic medicines. In many of these cases we find the medicine chiefly employed has been oil of turpentine, and I need not tell you that this is an excellent remedy in many cases of epilepsy totally uncomplicated with worms. The results of such cases do not necessarily prove that worms were the source of irri- tation. Again, immense injury is frequently done to children in persisting in the anthelmintic treatment for the supposed existence of worms. Recollect, the prominent phenomena of worms in the intestines are irritations of the digestive system and of other func- tions. Now, it is very well known that these symptoms may occur with or without worms. If, then, you have a case where these phenomena are present without the co-existence of worms—and if, under a mistaken impression, you treat it with anthelmintic medi- cines—you inflict a double injury: you exasperate the original disease by the drastic and irritating medicines which are ordinarily used for the removal of worms, and you do an indirect injury by neglecting to adopt proper means of treatment. There is nothing more common than to see children labouring under some irritation of the digestive tube, which is mistaken for worms, purged again and again, until they get incurable enteritis or tabes mesenterica. When a child has foul tongue and breath, picking of the nose, diarrhoea, and turbid urine, it is a common notion that he is labour- ing under worms. If he gets feverish, it is said to be worm-fever, and the anthelmintic treatment is pursued with unabated vigour. Now, I believe that a great majority of such cases are, in reality, disease of the mucous surface of the intestine, and that the conse- quent feverishness is dependent on this state. Another reason why you should be cautious is this: in persons of an hypochondriac SYMPTOMS OP INTESTINAL WORMS. 173 habit, there is nothing more injurious than their getting the idea that they have a worm in their bowels. When once this notion gets into the head of an hypochondriac, it is generally impossible to eradicate it. Some of the most melancholy and fixed cases of hypochondriacism are produced in this way; every symptom is attributed to the worm; the patient is in a state of constant feverisn anxiety about it; he talks of nothing else, and is constantly taking medicines to expel it, to the great detriment of his general health and with a manifest exacerbation of his symptoms. Medical men should be extremely cautious on this point. The patient is perhaps a female of hypochondriac and nervous habit; she has gnawing sensations about the epigastrium, which she supposes to depend upon the presence of a worm, and an injudicious practitioner favours the notion. He gives her various medicines to expel the worm; no worm is passed; she becomes more anxious, takes more medicine, and gets weak and emaciated. She then begins to think that all the nutritious matter in her body is going to support the worm, falls into a desponding state, and continues for the rest of her life an incurable hypochondriac. We come now to consider the exciting causes of worms. On this subject I believe our knowledge is very scanty and inaccurate. The following, however, are generally looked upon as remote causes:—foul air, residence in damp and unhealthy situations, sedentary habits and want of wholesome exercise, over-feeding, the constant use of certain articles of diet—as farinaceous sub- stances, milk, cheese, sugar, &c. An eminent authority (Bremser) asserts, as I have already stated, that unabsorbed chyle in the digestive tube constitutes the most fertile source of worms. It is a common idea, that poor diet has a strong tendency to give rise to the formation of these animals, but it has been frequently observed that worms are met with in persons who are by no means in want of nourishment; and it is said, that, in cases where nutrition has been diminished in man and other animals, the worms die. If this be the case, it would appear that, so far from being the exciting causes of worms, poor diet rather tends to favour their removal. Uncooked vegetables and fruits are also reckoned among the causes of worms, but I believe this arises from the mistaken notion that the ova of intestinal worms occur in vegetables, and, being taken with them into the stomach, are there developed, or even changed in their organisation—a position which we have already proved to have no foundation in truth. Persons who live principally on vegetable food have not been observed to labour under worms in a comparatively greater degree than those who use an animal diet. It is said that the Swiss, who consume a great deal of vegetables, are very subject to worms; but other nations, who live in a similar way, have not been remarkable for the same liability. Worms have been stated to be occasionally epidemic. It is not very easy to determine this point, but it has been remarked that, at particular periods, these animals have been more than usually fre- quent and numerous. Many authors have described an epidemic 174 STOKES’S THEORY AND PRACTICE OF MEDICINE. of what has been called verminous fever; that is to say, fever of a gastric or bilious character accompanied by worms in quantity. It is hard to say what the nature of this fever really was, and whether it might or might not be fever with irritation of the digestive appa- ratus, one of the consequences of which was a discharge of worms already existing. That worms are endemic, is a proposition very easily conceived; for we see it illustrated by the extraordinary prevalence of these animals in sheep which are kept in low, damp pastures. In such situations worms are met with in great abun- dance in the liver and other parts of these animals. It would appear from the following remarkable case, detailed by Bremser, that the use of milk and farinaceous food predisposes to the formation of intestinal worms. This gentleman, who was phy- sician to a monastery, and had ample opportunity of studying the habits of its inmates, was called to visit one of the oldest of the monks, who was said to be labouring under great derangement of the digestive system. On enquiry, he found that the patient had lived for sixty years in excellent health, using animal food, which, however, he had been latterly induced to change for farinaceous diet and milk. For a few days this agreed tolerably well with him, and then he began to be tormented with colicky pains, flatulence, sour eructations, and other distressing symptoms. His physician gave him some purgative medicine, and he passed a large quantity of tape-worm with relief: the treatment was persevered in, his former mode of living resumed, and he recovered quickly. This case bears strongly against the fanciful hypothesis that the ova of worms are transmitted in the act of generation ; for how could it be possible that the ovum of this tape-worm, transmitted in this manner, could remain undeveloped in the system for the space of sixty years ? This case derives additional interest from the fact of a change to a farinaceous diet being apparently connected with the formation of worms. Another remarkable case is given by the same author. The patient was a married female who had twelve children—six boys and six girls. This woman observed, that whenever she was preg- nant of a girl she had a great longing for milk and farinaceous food, and lived on these articles of diet almost exclusively. After living in this way for some time, she uniformly got an attack of worms ; and this, as well as the longing for vegetables, coincided with the birth of a female child so invariably, that she was able to tell with certainty whether the child she carried was a male or a female. This is a singular and well authenticated fact. We come now to the treatment of worms. Generally speaking, this is extremely simple—the principles of treatment in the various kinds of intestinal worms being nearly the same. Simple as they are, however, some persons entertain false notions respecting them. They appear to think that all they have to do is to evacuate the worms; and, having accomplished this, they rest satisfied, and take no steps to prevent their recurrence. But the mere evacuation of worms is no proof of a cure; to effect this you must prevent their SYMPTOMS OF INTESTINAL WORMS. 175 return. From what you have learned with respect to their exciting causes, you will be able to give such directions as to the patient’s mode of living as will obviate their recurrence ; and, with regard to the means to be adopted for removing them, we may divide them into the following:—We have, in the first place, what is called the mechanical treatment; next, the specific ; and, lastly, the purgative treatment. The first and last are nearly connected. For instance, purgatives appear to act in the same way as mechanical anthel- mintics, by irritating the mucous surface of the intestine and the worm, and thus causing its dislodgment and expulsion. Among the principal mechanical anthelmintics are filings of tin, couhage, powdered charcoal, and crude mercury; among the spe- cific are a variety of substances, most of which have a strong and peculiar smell. This is a very curious fact. Valerian, asafoetida, camphor, ether, and other odorous substances, have been found to be anthelmintic; and the Geoffraea inermis, which has been em- ployed for this purpose, is remarkable for its strong, unpleasant odour. The same thing may be said of tobacco, the oil of cheno- podium or wormseed, garlic, artemisia absinthium, and many others. With respect to purgatives, there is not one in the whole list, particularly those of the drastic kind, which may not be looked upon as an anthelmintic. It is the opinion of the most eminent men, that the thread-worm is the most difficult to expel, because they are generated with an extraordinary rapidity, and accumulate in a very short space of time. You are satisfied of their existence, have seen them in the alvine discharges, and the patient has all the ordinary symptoms. Well, what is the best way of getting rid of them? You shall commence by the exhibition of a mercurial. It is difficult to ex- plain why it is that mercury has such an effect in removing these worms, but the experience of the best practitioners can be adduced in proof of its efficacy. The statements of Dr. Latham, of London, and of many practitioners in this country and on the continent, go to prove this. In whatever way it acts, mercury appears to be a powerful anthelmintic; and it is a fact, that these worms have been expelled where it was given in very small doses, and not sufficient to operate as a purgative. The best plan is, first, to give a mercu- rial purgative, and then to have recourse to the mechanical treat- ment—giving, with this view, the syrup of couhage, one of the most efficacious of this class. It is a remedy which is easily man- aged, and will do no harm; for, though it produces violent itching when applied to the cutaneous surface, it produces very little sensible effect on the intestinal mucous membrane. The form which I employ is the following:—Take of the hairs of the doli- chos pruriens one scruple, syrup of orange-peel an ounce; of this an electuary or syrup is to be made, of which you may give a child a tea-spoonful three times a day. This is the remedy on which the West Indian practitioners, who have frequently to treat this affection in the negroes, place the greatest reliance; and you will find that, if you employ it, a vast number of worms will be often passed. It 176 STOKES’S THEORY AND PRACTICE OF MEDICINE. should be continued for two or three days, and then a purgative must be given, after the operation of which it may be again resumed if necessary. An excellent adjuvant to this is the use of aloetic injections, composed of two parts of milk and one of the decoction of aloes. In this way you will be able to remove a vast quantity of these little animals from the rectum. It has also been observed, that injections of cold fresh or salt water have a great power in promoting their expulsion. Bremser mentions, that, in cases where these worms pass from the rectum into the vagina in females, and excite irritation, there is nothing so effectual in destroying them as injections of cold water and vinegar. This you should bear in mind. You should also remember, in the case of administration of syrup of couhage, to give strict orders not to let any of it drop on the child’s skin, as it would excite a great deal of irritation. You should forewarn the attendants of its effects on the skin ; and if any of it should be spilled on the hands, neck, or face, the best thing is to wipe and wash the part well, and then rub it with a little almond oil. For the expulsion of lumbrici there is nothing so successful as the ordinary purgative treatment. A bolus, composed of calomel, rhubarb, and jalap, will answer this purpose extremely well; you may also use the syrup of couhage with much advantage. Brem- ser gives a formula for an electuary, which I have not tried, but have no doubt of its value, for it appears to combine all the qualities of a good vermifuge electuary. It is made as follows:—Take of the seeds of santonicum, and of the flowers and leaves of tansy, reduced to powder, each half an ounce. Here you have two anthel- mintics of the specific kind. Add to these two drams of powdered valerian: here is another. You then combine with these two drams of sulphate of potass and a dram and a half of jalap: these are purgatives. You then make them up into an electuary with syrup of squill, which is also an anthelmintic of the specific kind. Of this electuary two or three tea-spoonsful are to be taken during the course of a day. Bremser states that this combination is of great value, particularly against lumbrici and tape-worm. The treatment of tape-worm is not difficult. All the specific and mechanical anthelmintics are useful in promoting its expulsion, but there is nothing which appears to have such a powerful effect as full doses of turpentine and castor oil. This constitutes the best remedy we possess against the tsenia; but, if you wish to get rid of it entirely, you must give the turpentine in full doses. You will frequently be astonished at the vast quantities of this worm which will be passed. When you give turpentine, it is safer to order a full dose of it; for, if it be given in small quantities, it is very apt to irritate the urinary organs. Half an ounce of turpentine, with the same quantity of castor oil, form an efficacious though very disagreeable draught. You may, however, obviate its nauseous- ness by the addition of a small quantity of camphorated tincture of opium and mucilage of gum arabic. The celebrated empyreumatic oil of Chabert is, in my mind, nothing more than a modification of painters’ colic. 177 the turpentine. This is the remedy which Bremser looks upon as most efficacious against the tape-worm. You have all, I presume, heard of the animal oil of Dippel—the oil which is produced by the distillation of bones or hart’s-horn shavings. To one part of this are added three parts of turpentine ; these are left to combine for four days and then distilled; the first three parts of oil which come over are called the empyreumatic oil of Chabert. It is an exceedingly nauseous remedy, has a most disgusting smell, and is seldom used in this country. Bremser recommends it to be taken in doses of a tea-spoonful three times a day. Some persons who have tried it have assured me that it is extremely difficult to be taken, and that it excites a train of most disagreeable abdominal sensations. Bremser, however, thinks highly of it; he is in the habit of directing his patients to take it for three or four successive days, then to omit for a day or two, and then to return to it again; and he says that it not only succeeds in evacuating the worm, but also in preventing its return. In addition to this, he recommends the use of a fortifying tincture, which I think very useful in worm cases. It is a combination of one of the salts of iron with a pre- paration of aloes. If you take equal parts of the muriated tincture of iron and tincture of aloes, you will have a remedy somewhat similar to the strengthening tincture of Bremser. Twenty drops of this mixture, taken three or four times a day, will prevent the recurrence of worms. In our next lecture, I shall take up the subject of painters’ colic, and some other affections connected with the viscera of the abdo- men, and then pass on to the consideration of thoracic diseases.

A great deal of our time has been already occupied with the dis- eases of the digestive system—in fact, much more than I originally intended; the only apology I have to make for this, is the deep and paramount importance of the subject. Before I quit this part of the course, there are yet one or two subjects to which I shall briefly allude, namely, peritonitis and painters’ colic. With respect to the first of these diseases, I shall say but very little; the ordinary form of peritonitis is a disease so well known, and so fully treated of in books, that it would be only a waste of time for me to go over it; and with respect to peritonitis from perforation, all the original 178 STOKES’S THEORY AND PRACTICE OP MEDICINE. information I could communicate on this part of the subject, may- be seen in one of my published clinical lectures, and in the article on Peritonitis from Perforation, in the London Cyclopaedia of Practical Medicine. The ordinary form of peritonitis has been described in this work by Dr. M‘Adam, the disease from perforation by myself. I shall therefore pass over this subject, and proceed to the consideration of a very interesting disease—painters’ colic. This disease is called painters’ colic, from the circumstance of house-painters being extremely liable to it from coming into fre- quent contact with the poison of lead. Its synonyms are numerous, dry colic, Saturnine colic, rachialgia metallica, Devonshire colic, &c., &c. Painters’ colic is an example of the effects of a metallic poison on the nervous system. There are certain metals which produce a powerful effect on the system, not by means of their corrosive properties, or by any direct action on the surface to which they are applied, but by a peculiar impression made upon the nervous system. Thus we find that mercury, under certain circumstances, will give rise to a very singular nervous disease ; arsenic may be introduced into the system in such a way as to produce symptoms of nervous lesion; copper exercises a similar morbid influence, and the effects of lead are universally known. I do not mean to say that all these metals produce similar effects on the economy, for this is not the case; but there is one point of agreement between them, that all may produce symptoms which are called nervous or neurotic, and the diseases thus produced are classed among the neuroses. What is the meaning of this term neurosis ? A lesion of nervous function., more or less complete, occurring independ- ently of any demonstrable organic change. A neurosis, then, is an alteration in the functions of the nerves of organic and animal life, the nature of which alteration we cannot understand, neither can it be demonstrated by the knife, nor by any examination of the state of the nervous tissue. In other words, a person will die with the symptoms of a neurosis; and when you come to examine the body, you will be unable to detect, in the minute ramifications of the nerves, the trunks, or the nervous centres, any appreciable lesion. Diseases of this description have been divided into two classes— active and passive neuroses. Active neuroses signify an increase or exaltation in the nervous function ; passive neuroses are those in which there is a diminution of nervous energy ; in both, there is an absence of perceptible organic change. Take, for instance, an example from the nerves of animal life: a case of convulsions, independent of organic disease, is an example of the active neurosis; a case of paralysis, under similar circumstances, is an example of the passive. In the former, there is an exaltation of the nervous function, Avhich is reflected upon the muscular system; in the latter, there is a diminution, producing a partial or total loss of the power of motion. It has been asserted, by eminent physiologists, that passive neurosis can only exist in the organs of the life of painters’ colic. 179 relation, because the functions of the ganglionic system, which presides over organic life, cease only at the death of the individual. But there may be such a thing as semi-paralysis of the organs to which the ganglionic nerves are distributed; and hence we may have passive neuroses of the system of organic as well as of animal life. We get a good idea of these neurotic affections, by taking some of the most remarkable instances of this kind. Hydrophobia is a remarkable instance of excessive lesion of the nervous function, without any known organic change; so is tetanus, and so are some forms of apoplexy, convulsions, and mania. Here we have violent irritations of the nervous system, in which there is no perceptible organic change; and where the only information we derive from pathological anatomy is of a negative character, telling us what these diseases are not, and leaving us, as to their actual nature, as much in the dark as ever. We find by dissection that hydrophobia, and tetanus, and hysteria, and convulsions, and apoplexy, are not caused by inflammation of the brain or spinal marrow, and that is all. Hydrophobia, tetanus, convulsions, and hysteria, are instances of active neurosis; paralysis and apoplexy, without any known cerebral disease, are looked upon as examples of the passive kind, because they present either a diminution or abolition of the nervous function. In the present state of medical science, we must admit this division of the affections of the nervous system into diseases with and without perceptible organic lesion. I grant that it is very diffi- cult, when we come to consider alterations in the functions of parts, to conceive how such changes could be effected without molecular alteration, or that the brain could be deranged in its functions, without some change of this kind. We are, however, compelled to consider such functional alterations of the nerves as changes with which we are unable to connect any process of hardening, or soft- ening, or anomia, or congestion, or, in fact, any known pathological condition. Rostan is of opinion that all diseases are organic ; that is to say, that they are produced by some molecular change, and this, he says, should be the basis of medicine. Unfortunately for medicine, it has been given so many bases, that it sometimes knows not what leg to stand on. But to return to our subject. Painters’ colic is an example of a neurosis, that is to say, it is a lesion of the nervous function, uncon- nected with any known pathological alteration. It presents, com- monly, two periods—the first exhibiting the phenomena of active, the second of passive, neurosis ; or, in other words, the signs of exaltation of the nervous function precede those of depression. In the majority of cases, we find the first stage of this affection charac- terised by violent spasm, pain and convulsions, symptoms indicative of active nervous lesion; whereas in the second stage we have paralysis, the diagnostic mark of the passive kind. This is the order in which the phenomena of painters’ colic are generally met with, but in some cases the first stage is either very imperfectly shadowed out, or even entirely wanting; the paralysis comes on in 180 STOKES’S THEORY AND PRACTICE OP MEDICINE. an insidious manner, and without being ushered in by any symp- toms of exaltation of the nervous function. In this country, the most common victims to this disease are painters, who are much in the habit of working in white lead, and when you are connected with the management of any public medical institution (as I hope you will all be), you will often have to treat cases of this description. In Dublin, and all large cities, it is an exceedingly common affection, and the patients are for the most part house-painters. Next to these, the persons who are most subject to it are plumbers, and those who are employed in the melt- ing of lead. When the poisonous particles of lead enter the system in a highly volatilised state, its morbid effects are more certain and extensive. Every house-painter will tell you that the kind of work which is most likely to produce a deleterious effect, is painting “ the dead white,” or, as it has been termed, statuary white. In doing this, they use white lead combined with a large proportion of the oil of turpentine; and, in order to produce the intended effect, they are in the habit of excluding the air as much as possible. By means of the turpentine and the warm temperature of a close room, the lead is volatilised, and, in this state, appears to have an extraordinary power of impregnating the system. Some of the very worst cases of painters’ colic are produced in this way. Painting in the open air, even where the same preparation is employed, is comparatively harmless. A poor fellow, who was for a considerable time under my care, assured me that he had escaped for twenty years, and was convinced that he would have enjoyed a much longer immunity, had he not been put to work at the statuary white in a close room. With respect to plumbers, it is now ascertained that this disease is of comparatively rare occurrence among them; and the reason of this is, that they generally work in the open air, or in well ven- tilated apartments, and have now but little to do with the actual manufacture of lead. The kind of lead which they generally use, sheet and pipe lead, is furnished from the manufactories, and their occupation principally consists in the moulding and soldering of it. We very seldom now see a plumber labouring under colic. Painters’ colic may be observed under a great variety of forms ; but, for the convenience of studying the disease, we may divide these varieties into four classes. In the first, we have the pheno- mena of simple colic, without any obvious or marked symptoms of bilious, gastric, or cerebral derangement. In the second variety, the disease assumes a more decided character ; the colic is compli- cated with symptoms of fever of a gastric character, the pain in the belly is more acute, the constipation more obstinate; there is pain and difficulty in going to stool, nausea and vomiting, with occa- sional headache, dyspnoea, and sense of constriction about the prae- cordia; the belly is hard and retracted, and there is often pain in passing urine. In the third variety we have a more formidable array of symptoms. The functions of the brain and spinal marrow are deranged; there are wandering pains in the extremities; and painters’ colic. 181 the patient has frequent attacks of violent convulsions, resembling those of epilepsy. He also labours under the abdominal symptoms, but in this stage they are not so well marked, or so distinct, as in the former; the lesions of the functions of the cerebro-spinal system begin now to exhibit a greater degree of preponderance, and claim the principal share of the attention of a symptomatologist. In the fourth variety there is paralysis, without being preceded by the ordinary symptoms of abdominal or cerebral derangement. A medical friend of mine met with a case of this kind not long since. He was called to visit a child who had lost the use of his limbs. He went, and found the child lying in bed perfectly quiet and easy, his intellect sound, and his spirits good, but labouring under com- plete paralysis of all his limbs. He enquired minutely into the history of the case, and made a most scrutinising examination, but, from all he could see or learn, there was not the slightest ground to suspect disease of the brain or spinal cord. There had never been any symptoms of colic. He was puzzled with the case, and tried one thing after another without benefit. At length he found out that the child’s father was a painter by trade, and this led him to suspect that the symptoms might have some connection with the poison of lead. He enquired; and was told by the mother, that a quantity of white paint had latterly been kept in the room, and that it was impossible to keep the child from it. He instantly had the paint removed, a free current of air admitted into the room, and by the use of purgatives, assisted by stimulating frictions, the child recovered. The following is the order of symptoms generally observed in this disease. First, we have the precursory, denoted by pain and sensation of weight about the epigastrium; a weak, small pulse; general languor and weakness of the muscular system; want of appetite ; cold, clammy skin; a tremulous and coated tongue. At this period there is sometimes diarrhoea. Then comes some excit- ing cause, exposure to cold or wet, excess in eating or drinking, and the disease sets in with more or less intensity. The patient is attacked with dreadful pain in the belly, which differs from the pain of inflammation in this, that, so far from being increased by pressure, it is in most cases relieved. In fact, so decided is the relief produced in this way, that there is a case on record in which the patient used to get the greatest ease by making one of his fellow-workmen stand upon his belly. This relief from pressure is very generally observed in colicky affections. Indeed, so general is it, that you will hear it frequently stated, that all cases of colic are relieved by pressure. This, however, is not invariably true} for I have seen cases where the patients could not bear pressure, and where it required a careful examination to distinguish the symptoms from those of inflammation. The pain is of a twisting kind, and felt about the umbilicus; and, in connection with this, there is scanty urine, with more or less pain in passing it, obstinate constipation, and a tense, hard, retracted state of the belly, from the violent contraction of its muscles. The upper portion of the belly 182 STOKES’S THEORY AND PRACTICE OF MEDICINE. is sometimes more retracted than the lower, and the pulsations of the abdominal aorta are unusually distinct. The pain remits, and then becomes exacerbated, and the patient’s countenance is expres- sive of acute suffering. In that form of the disease where there is a complication of gastric or bilious symptoms, the patient has a semi-jaundiced look, a hot, moist skin, quick pulse, foul tongue, vomiting, hiccup, thirst, and epigastric tenderness. In the third form, the chief force of the poison seems to be directed against the brain and spinal cord. There is vertigo, headache, stupor, and sometimes delirium; the patient has fits resembling those of epilepsy, but of longer duration, and violent convulsions, which sometimes continue with unabated intensity for twelve, or even twenty-four hours. You will see those unfortunate creatures rolling and twisting in every form, sometimes doubled forwards, sometimes in a state of perfect opisthotonos, sometimes moving their limbs with the convulsive action of an epileptic, and foaming at the mouth. In addition to this, it is stated, in the descriptions of this disease, that the patient loses his sight, and becomes amaurotic; this I can confirm, for I have seen it more than once. It is a curious fact, too, that this blindness may come on before the other cerebral symptoms are developed. I recollect a case in which one of the first symptoms was blindness. The patient happened one evening to be indulging himself in whiskey punch, and was in a fair way of getting comfortably drunk, when, unfortunately, he found that all of a sudden he could neither see single nor double. He groped about in a very disconsolate state for his glass, but not finding it, and finding, at the same time, that he had lost his sight, he came to the hospital next morning, and shortly after his admis- sion, had a violent attack of convulsion. In cases of this kind, I have generally found the pupils contracted. The patients toss about in bed, and are frequently found lying with their heads turned towards the foot of the bed. In some cases, the breathing has been stertorous for a length of time, and the head fixed, but the fingers and hands were flexible. I have seen cases in which the coma dis- appeared, and was followed by perfect blindness, lasting for two or three days, and then yielding to treatment. These symptoms, striking and extraordinary as they are, do not seem to depend on the same state of the brain as cases of other dis- eases which are accompanied by sanguineous determination to that organ. The reason I make this assertion is, that many of the most violent nervous symptoms, including profound coma, subside under the use of a stimulant treatment. I think we may look upon these symptoms as similar to what are termed the symptoms of the nervous apoplexy of the ancients. A case of this kind, which occurred in the Meath Hospital, is deserving of notice, from the singular effect produced by treatment. The patient was in a state of profound coma, but the head was cool, and the arteries had no inordinate pulsation. If this was a case which presented the other symptoms of apoplexy, I would have prescribed bleeding, leeches, and cold applications. But I reasoned thus—Here is a case in painters’ colic. 183 which there is no evidence of the existence of inflammatory action. Opium has been found to relieve the abdominal symptoms of the disease—may it not also relieve the cerebral ? I ordered the patient to have a free dose of laudanum in camphor mixture. In a few hours he awoke, sat up in his bed, and next morning we found the symptoms of coma had completely disappeared. In two other cases of a similar kind, I have given opium and carbonate of ammonia with the most favourable result. Dr. Clutterbuck mentions a peculiar symptom of this disease— a kind of gouty inflammation attacking the great toe, and followed by relief. I have not seen this. He states that the first joint of the great toe becomes red, hot, painful, and swollen, and that this remits by day and returns again at night. I have never seen this, nor have I ever seen those hard tubercles on the tendons in various parts of the body, which some authors have described. After these symptoms, vve come to a new class, namely, the pas- sive, characterised by paralysis of ihe muscles of animal life. It is remarkable that this paralysis seems to be principally a paralysis of motion, and that the power of sensation is seldom or never impaired. Generally speaking, the upper are more subject to paralysis than the lower extremities, and the right than the left arm. The latter circumstance is explained by assuming that the direct influence of the poison is more applied to the right arm. The paralysis of the arm is also frequently partial; the extensors lose their power, but the flexors do not in so great a degree. You will see a patient with his arm hanging by his side as if it were dead, but if you give him any thing to hold lie can grasp it firmly. I have known painters continuing to work with a semi-paralysed arm. There is also an atrophied condition of the affected part; and this sometimes comes on with such rapidity, that, in the space of a week or ten days, the affected limb will be scarcely half as bulky as the corresponding one. We cannot account for this remarkable emaciation on the principle of loss of motion alone, for the short space of time in which it occurs, in many instances, is opposed to our entertaining such an opinion, and we must look for some other explanation. On this point, science affords us no satisfactory information. This disease, notwithstanding all its terrible array of symptoms, is very seldom fatal. Hence the uncertainty which long prevailed as to its pathological nature. In the great majority of cases, where a dissection was made, the patients died of some other disease, which either occurred during its course, or had preceded it. All that appears to be established at present is, that there is no known organic change of the nervous system connected with this disease; that it occurs in all its forms without the co-existence of organic lesion, and that its exciting cause is the poison of lead. It was formerly supposed that all the preparations of lead, whether applied externally, or used internally, were capable of producing colic, but this doctrine is at present considered very questionable. It was thought that metallic lead, and all its salts, were capable of causing the disease ; but the morbid influence of this metal is now 184 STOKES’S THEORY AND PRACTICE OF MEDICINE. restricted by the best chemists and pathologists chiefly to its carbonate. This opinion, I believe, was first put forward by Dr. A. T. Thomson, the author of the London Dispensatory, in an interesting paper published by him in the tenth volume of the Medico-Chirurgical Transactions. The object of this paper is to prove that, of all the preparations of lead employed in pharmaceu- tical and other purposes, the carbonate is that which is chiefly poisonous, and that the acetate and sub-acetate are comparatively harmless. You have all, I am convinced, heard of cases of colic produced by the external use of the acetate of lead, and you will see some cases in proof of this opinion in Darwin’s Zoonomia, and other writings. There is a case on record of a woman, who having poulticed her ankle with this preparation, for the cure of a sprain, got colic and fell into a state of marasmus. I knew of a deplorable case of burn affecting the abdominal integuments, which was treated with a solution of the acetate of lead. After using it for a fortnight or more, symptoms of colic came on, which not being recognised, the lead wash was continued, and the woman died in great agony. Dr. Thomson explains all this in a very satisfactory way. He shows that the solution of acetate of lead, when exposed to the air, attracts a quantity of carbonic acid, and is thus converted into a carbonate; of this I have very little doubt, for you will find that, by exposing a solution of the acetate of lead to the full influence of the air, the carbonate will gradually be deposited in the shape of a white powder. In the same way we can understand why it is that a solution of the acetate of lead, added to fermenting poultices, may be converted into a carbonate by the carbonic acid which is evolved. It is also a fact, that the acetate can be used internally for a long time without producing any thing like deleterious effects. I have given it for weeks together in full doses, without its having been ever followed by colic, or any symptoms characteristic of the absorption of a poisonous matter. There are cases on record where as much as six drams of this salt have been taken internally with- out producing any sensible morbid effect. As far as my experience goes, all those cases, in which the medical use of the acetate of lead has been attended with disagreeable symptoms, were cases in which it had been used as an external application. There were two cases in the Meath Hospital in which this medicine was used externally, in which colic, and other indications of poisonous absorption, took place, but not a single one in which its internal employment had been injurious. An excellent practical rule is laid down by Dr. Thomson, that, where you wish to employ the acetate of lead inter- nally, you should take care to combine it with diluted acetic acid. Of the two combinations of lead with acetic acid, the sub-acetate is most liable to be decomposed and converted into a carbonate, so that, if you prevent this by mixing with the sub-acetate, or acetate, a certain quantity of distilled vinegar, there will be little or no chance of unpleasant symptoms being produced, even where the medicine is given in very considerable doses. We are, therefore, painters’ colic. 185 I think, justified in concluding that it is the carbonate of lead which is productive of poisonous effects ; and that where bad symptoms have resulted from the use of the acetate, it was in consequence of its being converted into a carbonate. I must, however, remark, that it has not been sufficiently proved, as yet, that the use of the acetate is perfectly safe. It is an interesting fact, that many of the lower classes of animals are subject to this disease. Burserius was one of the first authors who directed the attention of medical men to this singular occur- rence. I have got from my father an abstract of some observations made by him on this subject, during a visit to the lead hills in Scotland. He found that, in the pastures among these hills, and in their immediate vicinity, cows, horses, sheep, dogs, and even poul- try, were subject to colic from lead. The symptoms, also, in these animals were observed by him to bear a very close analogy to those of the human subject. Thus, for instance, in cows there was obsti- nate constipation with suppression of urine; the poor animals seemed to suffer from violent twisting pain in the belly, and sometimes were thrown into a state of furious excitement, running wildly across the country. He learned, also, that during that period it was calculated that at least one tenth of the cows in this situation had died of the effects of the poisonous absorption of lead. One of the most ordi- nary precursory symptoms, was the animal becoming what is called hide-bound; this was followed by obstinate costiveness, and there was much apparent suffering, with panting, starting, and slavering from the mouth. Where the cerebral symptoms were most promi- nent, the signs of abdominal irritation were by no means distinct; and this, as I have remarked, is the case in the human subject. In some, who had the head affected, and ran wildly through the coun- try, the secretion of milk was stopped ; and this accords, too, with the effect of lead on the human female. Another remarkable cir- cumstance is, that animals living in the vicinity of these lead hills have exceedingly difficult labours. Sheep are subject to epileptic convulsions and paralysis ; dogs have the head principally affected, they run across the country slavering at the mouth, as if in a state of hydrophobia, but they do not bite, and are in all respects perfectly harmless. In barn-door fowl, the generative function was injured, and the hens reared or brought there ceased to lay eggs. There is one fact, mentioned in these observations, which tends to confirm the opinion of Dr. A. T. Thomson, that the poisonous effects of lead are produced chiefly by the carbonate. A distance of very few miles from the valley, renders animals quite free from any liability to the disease ; but if they should happen to stray into the immediate neighbourhood, and particularly into a portion of low ground, flooded during the winter months by a river which runs along the valley from the mines, and which, in all probability, leaves behind an efflorescence of the carbonate of lead, they are very liable to be affected with colic. It is said, also, that the poison is produced by the volatilisation of lead in the smelting houses, the vapours of which are carried down the valley and through the 186 STOKES’S THEORY AND PRACTICE OF MEDICINE. neighbouring parts. Be this as it may, the Gaelic name of the valley signifies, the poisonous vale; and, as it is very probable that this name had been given in consequence of the deleterious qualities of the place long before the establishment of lead works, it tends strongly to favour the opinion that it is the water which contains the poison. The mode of cure employed by the shepherds in this place, is to give strong purgative injections, and remove the cattle from the influence of the poison, by sending them to new and healthy pastures. In this way they frequently recover ; and if we look to the cause of the disease, its symptoms, or mode of cure, we shall observe a striking analogy between it and the colic from lead in the human subject. I shall conclude this subject at my next lecture, and then go on to diseases of the chest. LECTURE XXII. Pathology of painters’ colic—Researches on the state of the nervous and digestive sys- terns—Treatment—Use of narcotics, purgatives, tobacco, &c. &c.—Treatment of paralysis from lead—Efficacy of strychnine and brucine—Colic from copper—Poi- sonous effects of mercury—Remarkable case—Affection of the respiratory muscles. We were occupied at our last lecture in considering the symp- toms of painters’ colic. I mentioned that it occurs under a variety of forms; that the symptoms are to be attributed to a lesion of nervous function independent of any known organic change; and that the same disease may be seen in animals which have been exposed to the poison of lead. There are some other facts con- nected with this disease, which should not be passed over, and which I am anxious to lay before you previously to entering upon the treatment. You will recollect that I introduced the subject by stating that painters’ colic belonged to the class neuroses, and that I endea- voured to show that this implied a lesion of function of any part or viscus of the body, frequently characterised by the most decided departure from the natural condition, and yet unaccompanied by perceptible organic change. I said, also, that it was hard to sup- pose the existence of great functional alteration, without any mole- cular change; but that, in the present state of science, we are compelled, for the want of a better term, to call these affections neuroses, in contradistinction to diseases in which there is organic lesion visible. To illustrate this point, take an example from two different cases. In one case of what is called dyspepsia, we have inflammatory, or, at least, sub-inflammatory derangement of the stomach : here the disease is traceable to organic change; in another we have symptoms of nearly the same character, and yet there is no organic lesion. Painters’ colic comes under the latter head; painters’ colic. 187 we observe symptoms of excessive functional lesion, but dissection does not exhibit any organic change. Pathological anatomy tells us what it is not, and we arrive merely at a negative knowledge of its nature. We have decided proofs of extraordinary lesions of the nervous system, and yet, when we come to the post mortem exa- mination, we cannot find any visible change to account for these striking phenomena. The old pathologists maintained that spasm of the intestines was the principal cause of the disease, and attributed the symptoms to their contraction. This opinion appears to have some founda- tion, when we consider the violent symptoms of colic which accom- pany this affection. Dubois de Rochfort has mentioned, that in such cases he has found intussusception of the intestines. De Haen says that contractions of the colon are very common ; and several authors make the same assertion. The results of more modern observation, however, are against these opinions. I have told you already, that in consequence of this disease seldom or never proving fatal, there is a degree of doubt attached to its pa- thology ; but it is an interesting fact, that where death from other causes has occurred during the existence of painters’ colic, the digestive tube has been found either in its healthy state, or with a few detached spots of vascularity, without any decided inflamma- tory character, and totally insufficient to account for the symptoms. This, which is all that pathological anatomy reveals, may be consi- dered as purely accidental, and only of occasional occurrence, so that we are compelled to look upon the disease as one in which there is great lesion of function without any organic alteration. In the hospital of La Charite, at Paris, a vast number of cases of painters’ colic have been treated. In the space of eight years five hundred cases of this description have been admitted ; out of these, five died while labouring under the disease; and the following is an abstract of the appearances observed on dissection. In the first case, there was rupture of an aneurism of the abdominal aorta, and the patient sank from loss of blood. On examination, the digestive tube was found in the natural and healthy condition—there was neither vascularity nor contraction. The subject of the second case died of apoplexy. The whole intestinal canal was found healthy, and, contrary to the doctrines of the school of Broussais, there was neither congestion nor vascularity. In the third case, the patient had fits of an epileptic character, in one of which he expired. The colon exhibited a slight degree of redness, but quite insufficient to explain the symptoms during life. In the fourth, the cause of death was the same, and, on dissection, the tube was found healthy. Another patient, after recovering from the symptoms of painters’ colic, got a sudden attack of asphyxia and died. His body was examined, but there was no trace of disease in the colon or any other part of the intestinal canal. Here we have five cases in which there was either no disease at all in the digestive tube, or, if there was any, the amount was quite insufficient to account for the symptoms. Louis, in a memoir which he has published, on 188 STOKES’S THEORY AND PRACTICE OF MEDICINE. sudden and unexpected deaths, gives a case of this disease where death occurred suddenly on the eighth day. The intestines were found to be in a healthy condition. Martinet gives two cases of persons who died of the cerebral symptoms while labouring under this disease: here, also, the tube was in the normal state. Thus we have eight cases with dissections detailed by various authors, all men of high professional celebrity, having no theory to support, and all agreeing in the statement that there is little or no appreci- able lesion of the digestive tube ; that in the majority of cases it is in a state of health; that no contraction exists; and that such morbid appearances as have been found must be looked on as accidental. There is one interesting circumstance in these cases which deserves to be noticed. With the exception of the first and fifth cases, all the patients presented that form of the disease in which the functions of the brain are decidedly injured. Here it seems probable that the cause of death was excessive irritation of the nervous system. Now, in the observations I made on the cases which were treated at the Meath Hospital, you will recollect I stated that where the cerebral symptoms were predominant the abdominal were more or less indistinct and latent, and that the cause of indistinctness, or even total absence, of these might he owing to the force of the disease being thrown upon the brain and spinal cord. Such was the case in the instances above recited, and such we have also seen to be the result in the case of those animals of an inferior order that have been exposed to the poison of lead. How far the predominance of cerebral excitement may explain the want of appearances of disease in the digestive tube may be a subject of consideration. What is the state of science with respect to the brain and spinal marrow ? Allow me here to call to your recollection the symptoms of functional derangement of the nervous centres, the coma, the violent convulsions, the amaurosis, the deafness, the delirium, the paralysis. All these are violent symptoms, and you would natu- rally expect to find them connected with some sensible alteration, some congestion, or inflammation, or ramollissement. But nothing of this kind can be discovered. In all the cases where death occurred under such circumstances, at La Charite, with the excep- tion of some slight appearances of cerebral lesion in the second, there was no perceptible disease in the brain or spinal cord. The membranes and substance of the brain presented their normal con- dition ; there was little or no fluid in the ventricles; the spinal cord was healthy and natural in consistence and colour, and there was no effusion into its sheath. All these circumstances led to the conclusion that painters’ colic is essentially a neurosis. Observe, too, how interesting it is to connect the circumstance of the absence of organic change with the singular fact which I mentioned in my last lecture, that the comatose symptoms of this affection may be treated with stimulants and opiates. Where we have coma with congestion of the brain, opium has the effect of increasing the painters’ colic. 189 symptoms ; here it was found to have a contrary effect. So that our experience and the results of pathological anatomy, as far as they go, appear to square exactly. We see, then, that painters’ colic is not inflammation of the intestines, or of the brain, or of the spinal cord, and this information, though of a negative character, possesses considerable value in a practical point of view. I do not know any cases of what have been termed neuroses, in which the bearings of pathological research on practice are so extensive and so satisfactory. It is a fortunate circumstance that this disease is seldom fatal, and it is some consolation to think that, although the patient’s suf- ferings are dreadful and often protracted, there is little danger of life, and that the complaint is almost always amenable to judicious treatment. I have been for some years in the habit of treating it in a routine way, and can speak from experience of its success—of course this treatment is to be modified by circumstances. Suppose a patient applied to you with violent pain about the navel, a hard and retracted state of the abdomen, obstinate costiveness, and the other symptoms which characterise an attack of painters’ colic; the first thing I would advise you to do is to prescribe a full opiate. Many persons would object to this, and say that there is constipa- tion enough already, and that opening the bowels would be much more likely to give relief. But opium does not here add to the constipation ; indeed, so far from doing this, it sometimes acts as a laxative. At all events, it is a remedy which is perfectly unobjec- tionable. Give, then, in the first place, a full opiate, it will have the effect of relieving the patient’s sufferings, and will enable you to gain time for the employment of other means. The next thing is to place the patient in a hip bath, and keep him in it as long as possible. Do not neglect this, for I know of nothing that gives more decided relief. I have often seen cases where the patient was quite easy while he remained in the bath, but experienced a return of the pain as soon as he left it. If you have no means of procur- ing a bath in this way ; the next best thing is to have recourse to emollient stupes containing some narcotic, after the manner first introduced by my colleague, Dr. Graves. One of the best of this kind is the tobacco stupe; if you cannot get this you may employ poppy-heads for the same purpose. The tobacco stupe is much better than the tobacco injection, because its effect can be more easily regulated, but in violent cases I am in the habit of combining both, employing the stupe during the paroxysms of pain, and throw- ing up a tobacco enema every four or six hours, until a decided impression has been made on the symptoms. In the success which has attended my distinguished friend Dr. O’Beirne’s treatment of tetanus by the use of tobacco we see an analogous effect. In this way you will succeed in giving relief; you should also prescribe a brisk cathartic, and this you may do without any fear of injuring the patient, or exciting intestinal inflammation. The insensibility of the intestines to the stimulus of even powerful purgatives is a cu- rious feature in this disease, and bears strongly against the idea of 190 STOKES’S THEORY AND PRACTICE OF MEDICINE. its being connected with any inflammatory condition of the tube. In the Hospital La Charite the treatment is routine; it consists of an emeto-purgative plan, which is continued day after day until the symptoms yield. The purgatives we employ in the Meath Hospital is croton oil, combined with castor oil and mucilage, or given in the form of pill. When the bowels have been freely acted on, the case generally goes on well. After the bowels have been opened, we continue the employment of the hip bath, the narcotic stupes, and anodyne injections, taking care at the same time to persevere in the use of purgatives. Andral makes a good remark on this point:—“ Here (says he) are cases in which, from some peculiar alteration in the state of innervation, the mucous surface of the bowels is rendered less sen- sible than in its ordinary condition, and can bear freely the stimulus of powerful purgatives. May not this condition also occur in other states of the economy ? We are, therefore, led to conclude that purgatives are not, in all cases, direct stimulants.” Painters’ colic has been treated in Paris by bleeding and leech- ing, but this has not been found so successful as the ordinary pur- gative plan. I have never seen a case in which general bleeding seemed to be called for except one, and this was a most violent case which had resisted the ordinary means of treatment for forty- eight hours. I recommended bleeding from its well known anti- spasmodic power ; a quantity of blood was taken, and soon after the purgatives began to act, and the patient got relief. With respect to leeches, I have employed them only in those cases which are accompanied with symptoms of fever and gastric irritation; where there is quick pulse, hot skin, foul tongue, thirst, vomiting, and epigastric tenderness. In such cases I have applied leeches, but my experience of them is, that the relief afforded is by no means so great, or so decided, as in cases of intestinal inflammation, and it is a mode of treatment which I do not by any means rely upon for removing the disease. After the violent symptoms have been subdued, the next thing you have to consider is, whether there is any paralytic affection, and how this is to be treated. If the disease be severe or of consi- derable duration, you may look for paralysis of one or both of the upper extremities with a good' deal of certainty. This part of the subject, I believe, more properly belongs to the consideration of nervous affections, but, as I have gone so far into the treatment of painters’ colic, I may as well give the whole together. The paraly- sis which follows this disease is different from that which is the result of apoplexy; it is a neurosis of the passive kind, and to be treated as such. The patient, some time after the occurrence of the usual symptoms of colic from lead, begins to complain of weakness in his arm, he feels some difficulty in extending his fingers or raising his hand to his head, and then the symptoms become more marked. The arm and fore-arm become rapidly atrophied, the paralysis principally affects the extensors, while the flexors retain a considerable share of power, the fingers are bent, and the arm hangs painters’ colic. 191 by the side. Here the first thing you should do is to adopt the treatment recommended by Dr. Pemberton in his work on Abdomi- nal Diseases, namely, to apply a splint to the inside of the fore-arm and hand, so as to counteract the preponderating influence of the flexors. Apply a splint to the fore-arm, wrap it up in flannel, and make the patient keep it supported by a sling. In this way you establish a kind of balance between the antagonist muscles, and place the extensors under favourable circumstances for bringing about a cure. If the patient has both arms affected, which is some- times the case, change the splint from one arm to the other every second day, and continue this alteration until the cure is com- pleted. You will next have recourse to the use of strychnine, one of the best remedies we possess in cases where the paralysis does not de- pend upon organic disease of the brain. This is a remedy which is given with good effects even in cases of paralysis from apoplexy, where there is reason to suppose that absorption of the clot has taken place. In a case of apoplexy, it can be employed only after some time and where depletive measures have been sedulously put in force, but in a paralysis of this description you may begin with it at once. Commence with the exhibition of one twelfth of a grain of strychnine two or three times a day, and go on increasing the dose gradually, until a grain, or even a grain and a half, is taken in the twenty-four hours. To ensure the exact division of this powerful drug, you should direct a grain of it to be dissolved in a few drops of alcohol, and then made into pills of an equal size with crumb of bread or conserve of roses. In this way you will succeed in bringing back the lost power of the muscles of the fore-arm and restoring its nutritive functions. I may mention here, that the atrophy of the paralysed limb, which occurs in this disease, cannot be accounted for by supposing that it is produced by want of exercise ; the emaciation is so rapid (sometimes taking place in ten days or a fortnight) that we can only attribute it to some unknown lesion of innervation. If the use of strychnine be followed by severe muscular twitches, pain in the head, or convulsions, you must omit it for some time, and then, when these effects have completely subsided, it may be resumed if necessary. You should also bear in mind that this remedy is one of those medicines which have been termed accumu- lative, that is to say, a patient may be taking it for a considerable time without any perceptible symptom, and then its effects explode suddenly, the quantity which has been accumulating in the system manifesting itself at once by symptoms of great intensity. Here you omit it immediately, and with a view of relieving the existing symptoms, prescribe a draught, composed of camphor mixture, ammonia, and opium. This has generally the effect of calming the nervous excitement, and you will seldom have any more trouble on this account. En passant, I would advise you, whenever you employ strychnine in private practice, to inform your patient of the occurrence of such symptoms, and tell him that there is no cause 192 STOKES’S THEORY AND PRACTICE OF MEDICINE. for alarm. Instead of strychnine, some of the continental practi- tioners are in the habit of prescribing brucine, and it is stated with considerable advantage. I have tried it in two or three cases without much apparent benefit, and I am inclined to think that it is decidedly inferior to strychnine. In France, however, it has been very largely employed, and has the reputation of being a remedy of considerable value in the treatment of paralysis. It has one advantage at least over strychnine, it can be much more easily divided and regulated, so far as respects the quantity given, as it is a much weaker preparation than strychnine, one grain of which is equivalent to six grains of brucine. In addition to these measures, I have seen much benefit result from the application of blisters and frictions, with stimulating lini- ments to the spine. It is also of importance to remove the clothes in which the patients have worked; they are frequently charged, saturated with lead, and have a considerable tendency to keep up the disease. I have often seen an attack of painter’s colic reappear so shortly after leaving hospital, and without any evident exposure that I could only attribute it to the circumstance of their garments being saturated with the lead. In the foregoing plan of treatment there is nothing new; it is, in fact, a routine practice, but it is one which is borne out by the results of pathology, and which, from long experience, I can strongly recommend. I may also remind you that the plan of treatment followed in the hospital of La Charite, which has more cases of this disease than any similar institution in Paris, is completely routine. Other metals besides lead, as, for instance, copper, produce effects somewhat analogous. Copper is said to produce salivation, colic, and vomiting. Brass-founders are liable to these symptoms, as also other persons employed in the manufacture of copper. I have not seen the disease, but it is said to be analogous to lead-poisoning, so far as colic is concerned; in other respects the symptoms differ. The convulsions are not so violent, nor is the paralysis or coma so frequent; there is often considerable fever, thirst, difficulty of respiration, prascordial anxiety, diarrhoea, and prostration of strength, so that it comes much nearer to ordinary intestinal inflammation with fever, than painters’ colic. Yet it is a curious fact, that, not- withstanding all this array of symptoms so closely bordering on inflammation, it has been found in Paris, where several cases of this disease have been seen, that it is amenable to the same treatment as painters’ colic, and that, under the use of purgatives, the fever, thirst, diarrhoea, and tenesmus subside. Mercury, under certain circumstances, will produce a most extraordinary affection, on which I shall here make a few observa- tions. The disease is not of very frequent occurrence, but it is of importance in practice to be able to recognise and treat it properly. It is a proposition well known to almost every one, that many bad effects have resulted from the abuse of mercury; and I need not tell you how many persons are injured by the empirical painters’ colic. 193 employment of this potent drug on all occasions and in all consti- tutions. It is a common opinion that mercury acts principally on the capillary and absorbent systems, but there can be no doubt that it also acts upon the nerves, and that in a very remarkable manner. I have seen cases where the constant use of calomel has produced a marked derangement of the nervous system, manifested by great irritability, tremors, hysterical excitement, and hypochondriasis. You will see in the various works on Toxicology an account of the effects produced by mercury on persons employed in quicksilver mines, and on tradesmen, such as looking-glass manufacturers and others, who come in contact with mercury. I shall read for you the notes of a remarkable case of this kind, which was some time back under treatment in the Meath Hospital. It may be called a form of the paralysis agitans from the effects of mercury. Similar cases have been described. A man, aged forty-six, was admitted into one of our medical wards in October, 1833. He stated, that from the time he was eight years of age he had been employed in a looking-glass manu- factory, and that his occupation principally consisted in what is technically termed the silvering of mirrors. In this process the operator’s right hand is repeatedly immersed in a vessel filled with mercury, while the left fixes a sheet of tin-foil, on which the metal is rubbed. Artisans while thus engaged are in the habit of using a muffle, which covers the mouth and nostrils. This the patient said he had never used, because he found that those who were in the habit of wearing it did not enjoy better health. For thirty years he continued to enjoy tolerable health, with the exception of some bleeding from the gums, with shooting pains and a sense of formication in various parts of the body, accompanied by a slight loss of power in the hands, which came on at various times, and was generally relieved by the use of ardent spirits. He had been frequently salivated, and when admitted had lost nearly all his teeth. The mode in which he lost them was this, gum-boils formed close to the roots of the teeth, which soon, after dropped out, and in this way the local inflammation subsided. About three years ago, he had an attack similar to that for which he had been admit- ted ; he went into the hospital and was put under an active anti- phlogistic treatment with relief. From that time up to the period of his admission, he had enjoyed tolerable health, except that the sight of the right eye was considerably impaired, and that his memory was slightly affected. He forgot the names of persons and places, and was frequently at a loss in endeavouring to recol- lect the persons to whom he had lent his tools. On being brought into the hospital he presented an extraordinary specimen of human suffering, and I was at first unable to give his complaint a name, the case being the first of the kind I had seen. It exhibited the phenomena of a violent spasmodic affection ; it was different from tetanus, or hydrophobia, or hysteria, but it bore some faint analogy to chorea. The head, arms, and fingers, particularly on the left side, presented a succession of quick, convulsive, jerking motions. 194 STOKES’S THEORY AND PRACTICE OF MEDICINE. The angles of the mouth were retracted, the eyebrows twitching, the head constantly thrown back, but the agitation scarcely raised the arms. The nostrils were spasmodically dilated. The sterno- mastoid, trapezius, scaleni, diaphragm, and the abdominal muscles were similarly affected. Their contractions were short, rapid, and painful. From the constant hiccup with which the spasms of the diaphragm were attended, and the jerking motions of the tongue, his speech was interrupted and indistinct. He was occasionally free from spasms altogether, but whenever he transmitted volition to any part of the muscular system, it became instantly affected. When he endeavoured to raise his foot from the ground, it quivered and fell quite powerless and useless. Whenever he attempted to carry a vessel to his lips he generally overshot the mark, carrying the vessel towards his ear, nose, or forehead, and spilling its contents over his face or neck, so that it was a common saying among the patients in the wards, that he did not know the way to his mouth. But if the vessel was applied to his lips by another person, he could swallow easily. A sudden blast of cold air, the application of a cold hand to the skin, or the abrupt entrance of any person into the wards brought on an attack of spasms. The muscles of the left hand and of the left side were affected much more than those of the right. The mental powers were not impaired, the patient was intelligent, and seemed anxious to communicate the particulars of his case. During the whole course of the disease he retained a full power over the urinary discharge and defecation. There was some slight tenderness on pressure over the fourth and fifth dorsal vertebrae, but the rest of the spine exhibited no increase of sensi- bility. His skin was cool and dry, his pulse quick, weak, and small, his bowels inclined to be costive, but easily moved by laxa- tives. Here we see a marked difference between this affection and painters’ colic. The treatment adopted in this case was very simple. Leeches were applied to the tender part of the spine, the patient was placed in a warm bath, and got some laxative medicine, followed by an opiate. He was also ordered to have a large flannel shirt, and to be placed in a warm comfortable bed. He passed the night tolerably well, and next day appeared to be much improved. I shall not continue the daily reports of this case, but shall merely mention, that after a few days a great improvement took place. The spasms of the left side continued, though much less severe. Those of the purely voluntary muscles on the right ceased, while the spasms continued in the respiratory muscles on this side. We found that all the muscles of the face which have been called respiratory by Sir C. Bell, the platysma, scaleni, pectoral, and intercostal muscles, and the diaphragm, were thrown into violent spasms, while the purely voluntary muscles remained in a state of perfect quiescence. I am not aware that this circumstance has been observed in any other case. As far as it goes, it tends to corroborate the views of Sir C. Bell. In the treatment of this case we employed narcotic frictions, particularly those composed of DISEASES OF THE NERVOUS SYSTEM. 195 the extract of belladonna, to the spine with considerable benefit. The patient was cured by very simple means, and at little ex- pense to his constitution. LECTURE XXIII. Diseases of the nervous system—Pathology of, unknown—Molecular change in the nervous centres—Difficulties of distinguishing arachnitis from encephalitis—Gene- ral and partial cerebritis—Symptomatology of—Diagnosis of—Preservation of intel- lect in—Production of general symptoms by local lesion. To-day we commence the consideration of the diseases of the nervous system, and here let me remark, that, even on the very threshold, we have to encounter several difficulties ; some depend- ing upon the great obscurity of the symptoms—some upon the want of correspondence between the symptoms and known organic changes, and some upon the necessarily imperfect nature of our classification of nervous affections. Many persons are in the habit of taking a limited view of the nervous system. They suppose that, when we speak of its diseases, we merely allude to affections of the brain and spinal cord; but the truth is that the nervous sys- tem, so far as regards organisation, is universal; and there is evi- dence to show that, even in parts and tissues which present no appearance of nerves or nervous communication, there resides a nervous power, either inherent in their organisation or derived from external sources, and by the latter mode, of nervous irradia- tion from surrounding tissues, has the sensibility of serous mem- branes been supposed capable of explanation. But there can be little doubt that even these tissues present nervous expansions, though of an infinite delicacy. They are, we know, supplied with white vessels, and doubtless have nerves corresponding to their vessels in size and function—nerves, insensible to us in health, but, when inflammation elevates the organ in the scale, capable of transmitting the most exquisite pain to the centre of perception. It seems, also, to be highly probable that nervous disease may com- mence not only in an affection of the brain or spinal marrow, but also in a similar condition of any part of the system. Again, if we admit the nervous system to be the governing and directing portion of the whole body, it is likely that some modification of that government precedes the alterations which take place in the circulatory and nutritive functions of other parts. Thus, in all diseases it may be laid down as a general rule, that there is an affection of the nervous system, either local or general; or, in other words, that there is no disease which we could name, which does not present signs of an affection of the nervous system, either quoad the suffering organ itself, or of an affection more general and dif- fused. If we take, for instance, a case of gastritis or hepatitis, we 196 STOKES’S THEORY AND PRACTICE OF MEDICINE. find a lesion of function in the nerves of the respective organs, which, in certain cases, seems local; bat, if the inflammation be intense and the fever high, we have superadded to this a sympa- thetic affection of the brain or spinal cord. The same thing applies to all forms of local disease; for in all there is an affection of the nerves, either confined to the suffering organ, or extending to the whole system. In reviewing the phenomena of nervous diseases, we find them presenting several varieties depending upon certain circumstances. In the first place, they vary according to the seat of the disease. We find that the signs and symptoms of affections of the cerebro- spinal system differ very considerably from those which character- ise diseases of the sympathetic nerves. Again, if we take any part of the nervous system, and examine its diseases, we find that here also there is a source of variation connected with the peculiar part affected. Thus, if we take the cerebro-spinal system, we find that disease of one part of it differs most essentially in symptoms from disease of another: we may have enormous and fatal disease of the spine without the slightest injury of the intellectual powers, but we seldom have disease of the brain, particularly of the surface, without a more or less appreciable lesion of the phenomena of the mind. To follow up this point, suppose we take the diseases of the brain itself, as compared with each other; we find that their symp- toms vary according to the locality, so that, whether we look to physiology or pathology, we must consider the brain as consisting of several distinct parts, and not as an inseparable whole. It is admitted, by many writers of high authority, that there is a differ- ence between the symptoms of disease affecting the periphery, and disease affecting the central parts of the brain; and there is reason to believe that we may be able, in many cases, to diagnosticate affections not only of the centre and periphery of the cerebrum, but even of other parts of the organ. The same variety occurs with respect to the effects of diseases of the nervous centres. In some instances we have, as the result of disease of the brain, a loss of muscular power, or of sensation, in different parts of the body—sometimes affecting the face, some- times one side, or even both; and these paralyses may be single or variously combined. It appears, then, that the component parts of the nervous system, by being to a certain extent separate and dis- tinct, furnish a very extensive source of variety in the phenomena of nervous affections. Lastly, we have the varieties which depend upon the nature of the lesion. We generally observe an obvious difference between cases of nervous disease, accompanied by some known change in the injured part, and cases in which no such change can be demon- strated. Thus, for instance, we know the symptoms of apoplexy, and that, in the majority of cases, it is a disease connected with some perceptible change in the circulation of the brain—as exces- sive distension of its vessels, or an effusion of blood on its surface or into its substance. We also have some idea of the nature of DISEASES OF THE NERVOUS SYSTEM. 197 inflammation of the brain; we know that its substance becomes at first red, then begins to soften, and finally is converted into a pulpy mass. Now, there are a number of symptoms which are so often and so constantly connected with peculiar organic changes, that, the symptoms being known, we can make a tolerably correct guess at the nature of the alteration, or vice versa. On the other hand, however, we have a large and important catalogue of nervous affections, in which the symptoms give but very unsatisfactory information as to the real nature of the disease, and to the elucidation of which the painful and long-continued investigations of the pathological anatomist have hitherto been directed in vain. Of the actual nature of a numerous, complex, and interesting class of diseases—the neuroses—we know nothing. All we can say of them is, that they are examples of lesions of function in various parts of the nervous system, presenting no trace of structural alteration appreciable by our senses. It is a startling fact, and one which must be a source of gloomy reflection to the pathologist, that many of the diseases of the nervous system, which present the most violent symptoms, are those in which there is the least perceptible organic alteration. Every man who has seen a case of hydrophobia, or tetanus, or mania, or epilepsy, has witnessed a train of extraordinary and horrible symptoms, infinitely worse than those which are seen to accompany even great organic altera- tions of the brain. Here, then, is a singular fact: that there is a part of the system presenting a series of diseases under this extraordinary law, that the most violent and frequently fatal symptoms are accompanied by the least perceptible organic alteration. Now, what is the nature of these neuroses ? To give you a familiar illustration, let us take a case of tetanus or hydrophobia as an example. Here we have a train of symptoms exhibiting the most frightful irritation of the nervous system; and yet, when we come after death to examine, with eager curiosity, the cause of all these appalling phenomena, what do we find?—nothing. There is no unequivocal, no con- stant, no prominent alteration of any part of the nervous system, to throw light upon the obscurity of our opinions, and enable us to fix the nature or locality of the disease. We lay aside the knife in despair, and bitter indeed is the consciousness of our ignorance. Two opinions have been entertained by pathologists with respect to those singular affections: one, that they are examples of some peculiar modification of the nervous influence, independent of any organic change. In other words, the pathologists who entertain this opinion hold, that the principle of life may be altered in its phenomena, and admit of modifications, independent of any mole- cular change. The supporters of this doctrine reason thus:—In the phenomena of neuroses we have a train of extraordinary and violent symptoms unconnected with organic change. Now, it is quite unphilosophical to say that there is organic change when we cannot see or demonstrate it; and, on the other hand, it is not absurd to suppose that we may have lesions or peculiar modifica- 198 STOKES’S THEORY AND PRACTICE OF MEDICINE. tions of the nervous principle, without any organic alteration. The other opinion is, that in the neuroses there is some organic change, the nature of which cannot be ascertained, in consequence of our limited powers of detecting elementary changes. In whatever light we view this question, it appears to be surrounded with difficulties. No one can deny that neuroses are very different from organic dis- eases of parts. If we compare them with that class which is most familiar to us—the inflammatory affections—we find a remarkable difference. In the first place, the neuroses may be brought on by causes not reckoned among those commonly capable of exciting inflammation. In the next place, their invasion is sudden, and their progress rapid; they arrive at their acme in a very short period of time, and subside rapidly. These are characters which do not belong to the ordinary forms of organic disease. Again, we often observe the utmost intensity of nervous pain without the co- existence of swelling, redness, or heat of the part affected. We find, too, that they are not to be subdued by the antiphlogistic plan ; on the contrary, several of them are either relieved or cured by an exactly opposite line of practice; and many cases, which would appear to demand the lancet, are known by long experience to be most benefited by stimulants. Lastly, the most accurate and well conducted investigations of pathological anatomy have failed in demonstrating the slightest organic change in these cases—at least, where changes are found, these are neither constant, competent, nor commensurate with symptoms ; so that, whether we compare the information we derive from symptoms, or the result of patholo- gical anatomy, we find a great difference between neuroses and organic diseases. It may be said, that, though they are not inflam- matory affections, they have some resemblance to them. This, however, is only a gratuitous supposition; for, even in the very worst cases, they present nothing analogous to the results of inflam- mation, and the brain and spinal cord are as free from perceptible organic change, in the majority of cases of fatal tetanus and hydro- phobia, as they would be in nervous affections of a slight and transient character. You must have been already convinced that it is difficult to form any clear or definite notion of the nature of neuroses; indeed, the only thing we can say of them is, what they are not. When we reflect on nervous phenomena, and consider how occult, how mys- terious, the properties of those organs which give rise to them are, we are struck with astonishment at the discrepancy between cause and effect. No medical man has ever witnessed a case of confirmed tetanus or hydrophobia, without being oppressed with a conviction of the imperfect and limited state of our knowledge of nervous disease. It may be very possible, that in these neuroses the change, though so slight as to escape our means of detection, does absolutely occur; and yet such is the nature of nervous phenomena, that we must admit that great and extraordinary effects are produced by very slight causes. Do we see any thing like this in nature?—any DISEASES OP THE NERVOUS SYSTEM. 199 remarkable alterations in properties depending upon apparently slight causes? We do—we see extraordinary changes taking place in the characters of various inorganic substances, (to which I need not particularly allude,) and there is no reason why the same thing should not occur in organic structures. On considering the doc- trine of Isomerism, I should be inclined to think that it throws some light on this obscure subject. In chemistry, it is a well-known though singular law, that the properties of two bodies may be essen- tially different at the same time that their respective component elements are, as far as our knowledge goes, identically the same; and the change, whatever it may be, appears to result, not from the abstraction or removal of any of the component atoms, but from their peculiar juxta-position. Now, it being admitted in chemistry that many bodies having the same constitution possess totally differ- ent properties, and this difference being explained by the different position of their elements, it does not seem strange if the same thing should take place in the phenomena of organised beings; and, if this be the case, we have a key towards elucidating the nature of these neuroses, and can conceive how an analogous change—a dif- ference in the arrangement of the molecules of the component parts of the nerves, or their centres—may produce new modifications of their properties, without making any distinct change in their nature, or adding or abstracting a single organic molecule. I am much inclined to adopt the opinion of those who think that, in the neu- roses, a peculiar organic change actually takes place, though we cannot demonstrate its existence; because, to reason on the pheno- mena of animal life, independently of organisation, is to plunge blindly into hypothesis, and retrace the errors of an antiquated and exploded school. In treating of the diseases of the nervous system, I regret that time will not permit me to enter into the subject as fully as I could wish ; all that I hope to be able to accomplish is, to give a sketch of some of the more prominent affections. The arrangement I pur- pose to adopt is the following:—1st, I shall treat of local inflamma- tions of the brain ; 2d, of general inflammations of that organ; 3d, of mere sanguineous congestion or hyperaemia of the brain; 4th, of apoplexy; and 5th, of the various forms of paralysis. In taking up the subject of cerebral inflammation, I beg leave to observe, in limine, that the brain may be attacked by general or local inflammation ; and further, that it may, as stated in books, be inflamed in its membranes or in its substance, or in both together. A great deal has been written to show that we can distinguish, dur- ing life, between inflammation of the substance and of the mem- branes of the brain. On this point, I believe, we may come to this conclusion—that inflammation of the membranes of the brain, or arachnitis, may be distinguished from some cases of local inflam- mation of the cerebral substance, but that it cannot, in the present state of our knowledge, be distinguished from general inflammation of the brain. We can, in most instances, make a distinction between local disease of the brain and arachnitis ; but, when the whole 200 STOKES’S THEORY AND PRACTICE OP' MEDICINE. substance of that organ is affected, our means of diagnosis fail. This, however, is not so much to be regretted, as the distinction is of very little consequence, so far as treatment is concerned. Here we arrive at the knowledge of a principle highly consolatory in the practice of medicine; namely, that in many acute cases where the diagnosis between two diseases of neighbouring parts is difficult or impossible, it is also, so far as regards immediate treatment, un- necessary. If we enquire what are the symptoms of membranous inflamma- tion of the brain, as laid down in books, we shall find them to be the following: pain, delirium, convulsions, alteration of sensibility, and coma. These are the symptoms which are generally given as characteristic of arachnitis; and it is quite true that they are ob- served in many cases of the kind. But the person must be dull indeed who thinks that such symptoms imply nothing more than an inflammatory affection of the membranes of the brain. Take, for instance, one of the most prominent symptoms—delirium; what does this imply?—that the portion of the brain which discharges the functions of intelligence or mind has been injured, and is ren- dered incapable of performing its office. No one will venture to assert that the membranes of the brain are the organs of thought, and that the delirium proceeds from their morbid condition: such a notion as this could not be entertained for a moment. What then are we to suppose? One of these two things—either that there must be inflammation of the substance as well as of the membranes, or that the substance of the brain must be affected in a neurotic manner without any actual inflammation. As far as delirium is concerned, it appears to me to be quite impossible to distinguish between inflammation of the brain generally, and of its membranes. The same rule applies to the other symptoms—convulsions, altera- tion of sensibility, and coma. I repeat, that all we can say on this subject is, that, in such cases, there is either inflammation of the substance as well as the membranes of the brain, or that, with the membranous inflammation, there is a neurotic condition of the sub- stance of the brain. Yet who, in such cases, can affirm with cer- tainty that the symptoms of derangement of the substance of the brain are merely neurotic, when inflammation is admitted to exist within the cranium, and when we know that the two inflammations commonly co-exist? The fact of delirium occurring so frequently in inflammation of the membranes of the brain, is of considerable importance, as show- ing, not that membranes of the brain have any thing to do with intelligence, but as supporting the opinions of those who believe the periphery of the brain to be the seat of the intellectual facul- ties ; and here is a fact which, as far as it goes, is in favour of the doctrines of phrenology. If we compare those cases of cerebral disease, in which there is delirium, with those in which it does not occur, we shall find that it is most common in cases where disease attacks the periphery of the brain, as in arachnitis. The cases in which we observe great lesions of the brain without delirium are DISEASES OF THE NERVOUS SYSTEM. 201 generally cases of deep-seated inflammation of a local nature, or inflammation of those portions of the brain which the phrenolo- gists consider not to be subservient to the production of mental phenomena. This fact, also, would seem to confirm the truth of the opinion of the difference in function between the medullary and cortical parts of the brain. It is supposed that the cortical part of the brain is the organ of intelligence, while the medullary portion performs a different function. It is, however, a curious fact, that in delirium the inflammation is generally confined to the surface of the brain, and that, in cases of deep-seated inflammation, the most important symptoms are those which are derived from the sympathetic affections of the muscular system. Partial encephalitis may be either primary or secondary. An example of the latter is that inflammation of the substance of the brain which supervenes on apoplectic effusion, tumours, or cancer. What we generally observe, in a case of this kind, is more an alter- ation in the functions of the muscular system, and less of the intel- lect. This alteration consists at first in an apparent increase of innervation in certain muscles of the body, and we generally find that one of the earliest symptoms of local encephalitis is the occur- rence of pain in some of the muscles of the extremities. This is a curious fact, but one which is well established. In partial ence- phalitis there is often but little, or even no pain in the head: and the only warning have of the approach of cerebral disease is the occurrence of pain in the extremities, followed by rigidity. Here are the two most prominent symptoms of the disease—pain in the muscles of the extremities, and then rigidity. Further, we have alternate spasms and relaxations of the muscles, in which, however, the power of the flexor muscles ultimately prevails; so that, if the disease be in the fore-arm, it may become permanently flexed on the arm, and the contraction of the fingers is sometimes so great as to drive the nails into the flesh. If it affects the leg, the heel may be pressed against the buttock sometimes so forcibly as to form a sore. As the case proceeds, the limb becomes more fixed in its new position, and every attempt to extend it causes pain. During the prevalence of these symptoms, it frequently happens that the patient does not feel pain in the head, or any diminution of intellectual power. The absence of pain in the part affected may be accounted for by recollecting that it is a general law, that all inflammatory affections of deep-seated parts are, to a certain extent, of a compara- tively painless character; and we may account for the non-exist- ence of any lesion of the mind, by remembering that the disease is partial, and confined to a portion of the brain which appears to have little or no connection with the intellectual functions. In cases of this kind, when the muscles of the face are affected, the phenomena are interesting, from their being (in the first stage) the reverse of those of apoplexy. The face is drawn from the affected side, and the tongue pushed, by the opposite half of the genio-hyo- glossus muscle, to the affected side. This is the spastic stage, when complete disorganisation has not yet occurred. But when this STOKES’S THEORY AND PRACTICE OP MEDICINE. happens, then the phenomena of the face are like those of apoplexy, because the opposite muscles, which were in a spasmodic, are now in a paralysed state ; so that the face is drawn to the affected side, and the tongue pushed from it, by the healthy action of muscles which are deprived of their antagonists. I mentioned before that delirium may not occur during the course of a partial encephalitis ; and I gave, as a reason for this, the cir- cumstance of the disease being of small extent, and confined to parts of the brain which do not discharge any of the functions of mind. Another explanation has been given, drawn from the con- sideration of the double nature of the brain. It is thought that, where disease exists in one part of the brain, sanity may be still preserved in consequence of the healthy condition of the corre- sponding part; but where disease attacks both hemispheres together, as in a case of arachnitis, then there is a distinct lesion of the men- tal faculties. The next stage of partial encephalitis is that in which the dis- eased portion of the brain breaks down, softens, and is converted into purulent matter. This stage is marked by a new train of symptoms. The first stage is characterised by pain occurring in the muscles of the face, or of the extremities of either side, and followed by great rigidity. The second stage is of a different cha- racter ; the rigidity and spasm of the muscles diminish, and are succeeded by a paralytic and flaccid state of these organs. Volun- tary motion on the affected side now becomes impossible, the organ on which it depends being destroyed. Now let us, for sake of arrangement, call the first, or spastic condition, the convulsive paralysis, and the second, the paralysis with resolution. In the first, or convulsive stage, the brain is affected in the first degree; it is labouring under irritation or actual inflammation, and the disease still holds out a tolerably fair prospect of relief or cure. But in the second stage a cure is impossible, and hence it is a matter of the greatest importance to commence our operations at an early period ; and, by having recourse to prompt and active treatment, give the patient every chance for a cure. In the partial inflammation of the substance of the brain, sen- sation is variously altered. In some cases motion is lost, while sensation remains intact; in others, sensation is partially or wholly abolished. In many instances the intellectual powers remain in all their integrity, or but little impaired, even after the occurrence of symptoms which mark the softening down of the substance of the brain, and its conversion into purulent matter. In a few there is, during the first stage of the disease, a slight alteration in the state of the intellect, marked by a certain degree of excitement or exalta- tion of the mental faculties, and this, on the supervention of the second stage, is exchanged for a state of depression. In fact, the morbid phenomena of the mind and of the muscular system, where they co-exist, appear to be regulated by the same laws. Where the disease is extensive, you can easily observe the injury of the mental faculties which accompanies the second stage ; the patient answers 203 DISEASES OF THE NERVOUS SYSTEM. slowly when questioned; his memory is weak, and his counte- nance has a stupid expression. But cases, even of extensive local suppuration, have been described by various authors, in which there was no lesion of the intellectual functions observed. These, however, generally admit of an explanation. Thus, in the cases recorded by Lallemand, the abscesses were situated in the cerebel- lum, pons Varolii, and other parts which are not supposed to have any connection with the phenomena of mind. There are several well-authenticated cases of extensive disease, not only of these parts, but even of the substance of the hemispheres, occurring without any appreciable lesion of the intellect. Thus, Mr. O’Hal- loran gives the case of a man, who, after an injury which destroyed a large portion of the frontal bone, had extensive suppuration of the brain, and lost an enormous quantity of the substance of one of the hemispheres, and yet preserved his intellect entire up to the moment of his dissolution. There is some difficulty in explaining this. It is an opinion entertained by some physiologists, that when one hemisphere is diseased its functions are discharged by the other; and that, the brain being a double organ, disease of one side does not impair the functions of the other. But, in answer to this, it may be urged that there are many cases on record in which disease of a single hemisphere has produced great alterations of intellect. The supporters of the former opinion attempt to explain such cases in this way. They state, that in the majority of such cases there was, besides the local encephalitis, inflammation of the arachnoid membrane, and that the lesion of intellect was not so much the effect of local disease of the brain as the result of its complication with an arachnitis engaging the whole periphery of the organ. In the next place, they explain the fact of a general affection of the brain arising from local disease, as depending in most cases on the pressure which the tumefied state of the diseased portion necessarily makes on the sound hemisphere ; and they state that this pressure must be very considerable, as the brain, being confined within a bony cavity, has no power of expanding itself. Now, it is a most interesting fact, in support of this view, that, in a great number of the cases of loss of brain with preservation of intellect all through the case, an extensive opening existed in the bones of the skull, so as to permit of expansion in the diseased hemisphere, and prevent the pressure being exercised on the opposite one. This point appears to be borne out by the result of Mr. O’Halloran’s cases, and by many other examples. Lastly, in every acute case of local inflammation of the brain, two causes having a tendency to produce symptoms exist. One of these is the local disease which gives rise to those phenomena of motion and sensation which we observe on the opposite side of the body; the other is the determination of blood to the whole brain, the result of the irritation of that disease. —“ If hi, stimulus ibi humorum affiuxusf 204 STOKES’S THEORY AND PRACTICE OF MEDICINE.

We were occupied at our last lecture in considering1 some of the phenomena of partial encephalitis, by which is generally meant, a localised inflammation of the deep-seated parts of the brain; because superficial inflammation of the cerebral substance is very rarely partial. I endeavoured to show that the diagnosis of this local encephalitis was to be drawn, in a great measure, from the occur- rence of pain and muscular affections of one side of the body ; in other words, that the phenomena of this disease were partial, so as to give us at once a distinction between general and partial inflam- mation of the brain. In cases of general inflammation, we have convulsions of both sides—delirium and coma; in the partial form these symptoms are absent until complication takes place. Thus the supervention of delirium, or of convulsions on both sides, in a case where previously the signs of only partial encephalitis existed, would point out, in all probability, an extension of disease to the opposite hemisphere. I also endeavoured to point out the different modes in which partial encephalitis might be accompanied with symptoms of a general character, or affecting both sides ; that there might be a co-existing inflammation of the membranes; or that the pressure of the diseased on the healthy hemisphere of the brain might be the cause of the complication. I stated, that some of the most remarkable cases of extensive destruction of the brain, without perceptible injury of the mental powers, were those in which a traumatic opening in the skull gave full scope to the swollen parts, and obviated the effects of pressure on the sound hemisphere. I also observed that, in cases of local affections of the head, there are two causes which have a tendency to produce general symptoms. One of these is the cause which determines the pain and muscular affection of the opposite side; the other is the general determination of blood to the head ; so that we may have cases in which the actual inflammation is limited to a part of one hemisphere, and yet, from the general determination of blood to the head, we may have coma and general symptoms. To return again to the interesting consideration of great loss of cerebral substance with preservation of intellect, I have to remark, that this circumstance is one which some persons might quote against the opinion that the brain was the organ of intelligence; and I believe this fact has been laid hold of by the opponents of phrenology, and put forward as a powerful argument against the truth of its doctrines. Thus, for instance, in the case of Mr. O’Halloran’s patient, who lost a large portion of one hemisphere, ENCEPHALITIS. 205 and yet, with all this mischief, the powers of the intellect remained unimpaired; it would not seem strange if a person should say, here is vast destruction of substance without any lesion of intelligence; how then can the brain be considered as the organ of thought? But let us look at this matter in its true point of view. In the first place, it is to be remembered that cases like this are rare—that they are to be considered as the exception and not as the rule. I have already shown you, that it is a law in pathology that lesion of structure and lesion of function are not always commensurate. This law applies to the brain as well as to all the other organs. To say that the brain was not the organ of intelligence, because in cases of extensive cerebral disease that intelligence was preserved, is false reasoning. A man will digest with a cancerous stomach ; is it to be argued from this that the stomach is not the organ of digestion ? I have seen the liver completely burrowed by abscesses, yet the gall-bladder was full of healthy bile. I have seen one lung completely obliterated, and yet the respirations only sixteen in the minute, and the face without lividity. What do these facts prove ? Not that the health of organs is of no consequence, but that with great disease there may be little injury of function. By reference to the original laws of organisation, we may (in some cases at least) arrive at an explanation of this fact. You know that organs are primitively double; and we find, that though the fusion at the median line is produced by development, yet that the symmetrical halves still, to a certain degree, preserve their individuality. Thus we see how the laws of organisation affect the phenomena of disease, and recognise a provision, acting from the first moment of existence, against the accidents of far distant disease. Now, admitting that the brain is the organ of thought, we may suppose that, as in case of partial obstruction of the lung from inflammation, the remainder of the organ takes on an increased action, so as to supply the place of that which has been injured or destroyed. We know that if one lung be hepatised. the other takes on its functions, and carries on the process of respiration for a time. That this is the case, is shown, first, by life being continued, and, secondly, by the stethoscope, which informs us that the respiration of the lung, which has a double duty thrown upon it, is remarkably intense, proving the force of its action ; and it has been further established, that the lung which thus takes on a supplemental action may become enlarged and hypertrophied. May not this also occur in the brain ? There is no reason why such a pathological pheno- menon, occurring in one viscus, may not also take place in another. But the opponents of phrenology say, supposing the organ of causa- tion to be destroyed, how can the person continue to reason ? It strikes me that the only way in which we can account for this is, by supposing that other parts of the brain take on the functions of those which have been injured or destroyed. Nor is there any thing extraordinary or anomalous in such a supposition. We see, almost every day, examples of this kind. We see that in certain 206 STOKES’S THEORY AND PRACTICE OF MEDICINE. diseased states of the liver, accompanied by suppression of its secre- tion, its functions are assumed by other parts, and bile continues to be separated from the blood by the kidneys, salivary glands, and by the cutaneous exhalants. Here is a remarkable case, in which the glands and other parts take on the performance of a function totally different from that in which they are ordinarily employed. We find, also, that when the urinary organs are obstructed, urine, or its principles, are discovered in parts of the system where we should not at all expect them. Thus we have a very remarkable case detailed in the American Journal of the Medical Sciences, in which we find that a young female, who laboured under paralysis of the urinary organs, discharged urea from almost every part of the body, even from the ears. Neither is there any thing very extraordinary in this. In several instances of suppression of the menstrual dis- charge, do we not see a vicarious secretion taking place from the surfaces of parts the most distant, and unconnected with the uterine system? It is a well-established law, that when the functions of organs are suspended or destroyed, other parts will often take on the action of the injured viscus. Now, supposing that a portion of the brain is to be looked upon as the organ of causation, and such portion is injured or destroyed, there is no reason why the remain- ing sound portion of brain should not take on, at least to a certain extent, in addition to its own, the functions of that part which has been injured. If, independently of any phrenological views, we admit the brain to be the organ of thought, there is no reason why we should not admit that the loss of intellectual power, produced by lesion of one part, may not be supplied by an increase of activity in the remaining portions. It is only by a supposition of this kind that we can account for the preservation of the integrity of mind in many cases of disease of the brain. If we admit the phrenological doctrines, we can suppose that when one organ is injured, another may take on an additional function, and in this way preserve the integrity of the intellect; so that, whether we reason from phreno- logy or not, the continuance of soundness of mind, in cases of injury of the brain, can be understood when you come to contrast it with other analogous pathological facts. I again repeat, that it is not more extraordinary that, in case of local injury of the brain, the sound parts should take on a supplemental action, than that bile should be eliminated by the salivary glands, skin, and kidneys, or that the principles of urine should be discharged from almost every part of the system, or that a vicarious discharge from the roots of the hair should supply the place of the uterine secretion. On this subject, one point should be always borne in mind, viz., that we may be wrong in saying that a patient is quite sane, while he is still an invalid and in bed. Unless we can show that after his recovery, and in his various intercourse with the world, he pre- serves his original intelligence, it would be wrong to assert that there has been absolutely no lesion of intellect consequent on the affection of the brain. While lying at ease in bed, and unaffected by any moral stimuli, he may seem to possess a sound condition of mind; he may put out his tongue, or stretch forth his hand, when requested; he may give an accurate account of his symptoms, and answer all the ordinary medical interrogatories with precision. But you are not, from this, to conclude that he is perfectly sane. Many persons, under these circumstances, have died in bed, and appeared to preserve their intellect to the last; but in such cases, the test of sanity, intercourse with the world, could not be fairly applied, and hence I think that there are not sufficient grounds to pronounce a decided opinion as to the real condition of the intellect in such cases. Before I quit this part of the subject, I wish to make a few remarks on the doctrines of phrenology. There can be no doubt that the principles of phrenology are founded on truth, and, of course, highly deserving of your attention, as likely, at some future period, when properly cultivated, to exercise a great influence over medical practice. The great error of the phrenologists of the pre- sent day, consists in throwing overboard the results of pathological anatomy. If a pathological fact is brought forward, as appearing to bear against the validity of their opinions, they immediately exclaim, “we dont recognise any fact or principle drawn from dis- ease ; our science has to do with the healthy, and not the morbid, condition of the brain.” Now, this is altogether absurd. Phreno- logy, if true, is nothing but the physiology of the brain, and patho- logy is nothing but the physiology of disease. Phrenology must be tested by disease as well as by health, and if it does not stand the test of pathology, it is wrong. If phrenology be a science founded on truth, if it is a true physiology of the brain, or of that portion of it connected with mental phenomena, one of two results should obtain—either that it should be confirmed by pathology, or that the difficulties, which pathology presents, should be explicable in a manner consistent with the science. The phrenologists, in my mind, are doing a direct injury to the cause of their science, by their unnecessary and ill-timed hostility to pathology. It is idle to say, as they do, that theirs is the science of health, and that it is unfair to apply to it the test of disease. From pathology is drawn a host of facts, from which the doctrines they profess derive their principal support. The mere phrenologist, who understands not and despises pathology, is nothing better than a charlatan, and pro- fesses a science which he does not comprehend. If he would recol- lect that the brain in a state of health is most, and in a state of disease least, adapted to the purposes of thought, he would see that this is one of the strongest arguments in favour of his doctrine, that the brain is the organ of mind. The more healthy it is, the fitter it is to discharge the functions of intellect, and vice versa ; yet phreno- logists are so absurd as to think that pathology has nothing to do with their science. But besides confirming the doctrine that the brain is the organ of thought, there are innumerable facts drawn from pathology, which have a tendency to prove that particular parts of the brain are the organs of peculiar phenomena. We see an injury of one part of ENCEPHALITIS. 208 STOKES’S THEORY AND PRACTICE OF MEDICINE. the brain, accompanied by a train of symptoms indicating some peculiar lesion of mind; we see an affection of another part, attended by a different class of phenomena. Here pathology, the science which phrenologists reject and despise, goes to establish the ground-work of their doctrines, that the brain consists of a congeries of parts, haying each a separate and distinct function. We find, for instance, that disease of one portion of the brain affects the intellect; of another, the generative organs ; of a third, the muscular system. What does this prove but that the brain is not a simple organ, but composed of a congeries of parts, each of which governs a different part of the system, or ministers to a peculiar purpose ? Now, what is this but what the phrenologists themselves wish to prove ? Further, the professors of phrenology have placed all their organs on the surface of the brain, and for this they have been loudly censured. Phrenology, it is urged, knows, or professes to know, nothing about the central parts of the brain, which must be equally important with the superficial, and have confined their investigations to the surface alone. Now it is a curious fact, that the pathology which they deny, in this instance, furnishes the best reply to this objection. I mentioned at my last lecture, that if we examine the symptom of delirium, we find that it characterises the inflammation of the periphery, and is commonly wanting in that of the deep-seated portions. In other words, mental alienation is the characteristic of the disease of that portion of the brain where the phrenologists have placed the intellectual organs. Here is a strong fact in favour of the doctrines of phrenology, derived from that science which the mere phrenologist throws overboard and despises. Again, according to the researches of some celebrated French pathologists, there are a number of facts to show that there is a remarkable difference between the symptoms of arachnitis of the convexity and of the base of the brain. This conclusion, which, after a most careful series of investigations, was adopted by them, is borne out by the results of my experience, and appears to me to be established on the basis of truth. They have discovered that arachnitis of the convexity of the brain is a disease characterised by prominent and violent symptoms, early and marked delirium, intense pain, watchfulness, and irritability. We have first delirium, pain, and sleeplessness, and then coma. But in arachnitis of the base of the brain, the symptoms are of a more latent and insidious character ; there is some pain, and the coma is profound, but there is often no delirium. What an important fact for the supporters of phrenology is this, and how strikingly does it prove their absurdity in rejecting the lights derived from pathology ! Here we find the remarkable fact, that inflammation of the arachnoid, investing the base of the brain to which the phrenologists attach, comparatively, no importance, is commonly unattended with any lesion of the intellectual powers, while the same inflammation on the convexity is almost constantly accompanied by symptoms of distinct mental alienation. It is objected to the phrenologists that they know little or nothing 209 of the central parts of the brain; that though these parts may be fairly considered to be of as much importance as any others, still they do not admit them to be organs of intellect. Now, what does pathology teach on this subject'/ It shows that we may have most extensive local disease of the central parts of the brain—that we may have inflammation, suppuration, abscess, and apoplexy, with- out the slightest trace of delirium. Indeed, there can be no doubt that the central portions of the brain have functions very different from those on the surface. They appear more connected with another function of animal life, muscular motion and sensation. Then let us examine the phenomena of old age. Every one is familiar with the fact, that when a man arrives at an extreme age, he generally experiences a marked decay of intellectual power, and falls into a state of second childhood. Does pathology throw any light upon this circumstance ? It does. From a series of ingenious and accurate investigations, conducted by two continental patholo- gists, Cauzevielh and Desmoulins, it has been found that a kind of atrophy of the brain takes place in very old persons. According to the researches of Desmoulins, it appears that, in persons who have passed the age of seventy, the specific gravity of the brain becomes from a twentieth to a fifteenth less than that of the adult. It has also been proved that this atrophy of the brain is connected with old age, and not, as it might be thought, with general emaciation of the body; for in cases of chronic emaciation from disease in adults, the brain is the last part which is found to atrophy; and it has been suggested that this may explain the continuance of mental powers, during the ravages of chronic disease; and also the nervous irrita- bility of patients after acute diseases, in which emaciation has taken place. I might bring forward many other facts to show that phrenology is indebted to pathology for some of the strongest arguments in its favour; and I think that those phrenologists who neglect its study, or deny its applicability, are doing a serious injury to the doctrines they seek to establish. The misfortune is, that very few medical men have turned their attention to the subject; and that, with few exceptions, its supporters and teachers have been persons possess- ing scarcely any physiological, and no pathological, knowledge. Phrenology will never be established as a science until it gets into hands of scientific medical men, who, to a profound knowledge of physiology, have added all the light derived from pathological research. To give you an instance of the mode of reasoning of the non-medical phrenologists. In their drawing-room exhibitions, they appeal with triumph to the different forms of the skull in the carnivorous and graminivorous animals, with respect to the develop- ment of destructiveness ; and all are horrified at the bump on the tiger’s skull. But, as Sir H. Davy well observes, this very protu- berance is a part of the general apparatus of the jaw, which requires a more powerful insertion for its muscles in all beasts of prey. Phrenology, as generally taught, may answer well for the class of dilettantis and blue-stockings, or for the purposes of humbug and ENCEPHALITIS. 210 STOKES’S THEORY AND PRACTICE OF MEDICINE. flattery; but its parent was anatomy, its nurse physiology, and its perfection must be sought for in medicine. The mass of inconse- quential reasoning, of special pleading, and of “false facts” with which its professors have encumbered it, must be swept away, and we shall then, I have no doubt, recognise it as the greatest discovery in the science of the moral and physical nature of man that has ever been made. I feel happy, however, in thinking that, of late, the science has been taken up on its true grounds, in Paris, London, and Dublin. Vimont’s splendid work on Comparative Phrenology will form an era in the science. In London, Dr. Elliotson has directed the energies of his powerful mind to the subject; and in Dublin we have a Phrenological Society, of which Dr. Marsh is the president, and my colleague, Dr. Evanson, the secretary; and, under such auspices, much is to be expected. Having drawn your attention to the ordinary symptoms of local encephalitis, our next enquiry is, how far we can diagnosticate the actual seat of disease from phenomena observed during the life of the patient. Do not suppose, for a moment, that this part of the subject is undeserving of your attention, in the strongest sense of the word. Recollect that the more accurate and extensive is diag- nosis, the more certain and available is the practice of medicine. On this subject, matters are not altered to the same extent as in the cases of chest or abdominal diseases. In our knowledge of the two latter, we have made vast strides within the last few years; but in cerebral affections, though much has been effected, much still remains to be done; and it is not improbable that some of the opinions on this subject, still promulgated in schools, require correction. If we examine the various cases of cerebral disease on record, we find that in some the paralysis was complete, and that sensation and muscular motion became, as it were, annihilated. In other cases, the muscular system alone appeared to suffer ; while in a third class we find that sensibility is destroyed, while the power of motion remains intact. Again, in some we have complete hemiplegia, in others the paralysis is but partial; in some the affec- tion is slight and transient, in others it is incurable and permanent. The result of all this would appear to imply that there are different states and seats of cerebral disease, producing different modifications of nervous phenomena. It has been taught, that a paralysis of the organs of speech points out a lesion of the anterior lobes of the brain, and there are many cases on record in support of this opinion. Here is a pathological statement strongly in favour of the doctrines of phrenology. But, on the other hand, it must be con- fessed that there are numerous cases on record of lesion of the powers of speech, independent of any affection of the anterior lobe ; and hence, as far as the diagnosis of lesion of the anterior lobe, derived from loss of speech, is concerned, we cannot make up our minds. You are aware that the phrenologists place the organ of language in the anterior inferior part of the brain. Now, when an affection of this portion of the brain is found to coincide with the loss of speech, it is all very well; but the difficulty is to account ENCEPHALITIS. 211 for those cases of loss of speech in which there is no appreciable lesion of the substance of the anterior lobe. In investigation on this point, however, you must bear the following distinction care- fully in mind. The organ of language of the phrenologists is not properly the organ of the power of speech, but that by which, as it were, thought is converted into language. A man, from paralysis of his tongue, might be incapable of speaking; and such a case, existing without lesion of the anterior lobes, might be most unfairly quoted against the phrenologists. Again, paralysis of the upper extremities has been connected with disease of the optic thalami, and posterior lobes of the brain. It is the opinion of Bouillaud, Serres, and others, that the optic thalami regulate the motions of the upper extremities; and it is a fact, that in many instances of paralysis of the upper extremities, disease has been found in these parts. We might term the following a synthetic case, illustrative of the doctrine:—“ A soldier was wounded in the right shoulder with a lance, in consequence of which, he got an aneurism of the axillary artery, for which an operation was performed. At the moment the ligature was tightened, he experienced exquisite pain in the situation of the ligature, which extended to the brachial plexus; this continued until the next day, and then ceased. On the fourth or fifth day the pain returned with increased violence, and continued until the seventh day, when it became intolerable. He was blooded, but without any good effect, he then became comatose ; his head was drawn backwards; he had alternations of stupor and excitement, and soon after expired. On dissection, the ligature was found to embrace some of the principal branches of the brachial plexus, and there was an abscess in the posterior lobe of the brain, extending to the optic thalamus.” Here we have a case of injury of the upper extremity, and that portion of the brain which is supposed to govern it was found in a state of manifest disease. Serres gives, also, the details of some experiments in sup- port of this opinion. On removing the posterior part of the right hemisphere of the brain in a dog, he found that the left anterior extremity became paralytic; he prolonged his incisions into the corresponding portion of the opposite hemisphere, and found that the right extremity became paralysed. In another dog he plunged a bistoury into the posterior part of the right lobe, and found that the left anterior extremity became affected with convulsive motions. He then introduced into the wound a few drops of nitric acid, so as to produce inflammation of that portion of the brain, and observed that the convulsions of the left fore-foot became more violent; in fact, that the animal had all the symptoms of a local inflammation of the brain, namely, convulsions, rigidity, and then paralysis. Rolando has performed a series of experiments with the same view, and his conclusions are exactly those of Serres. So that if we con- nect the results of these experiments with some facts drawn from pathology, we might conclude that the optic thalami, and posterior lobes of the brain, have a very important share in regulating the muscular motions of the upper extremity. I may here state, that, 212 STOKES’S THEORY AND PRACTICE OF MEDICINE. ill this city, a case of a female occurred, who got an attack of severe pain in the left hand and fingers, which became afterwards con- tracted ; and she had, in addition to this, alternate flexions and extensions of the fore-arm, followed by resolution and paralysis. On dissection, there was an abscess found in the right optic thala- mus ; the rest of the brain was healthy. With respect to those cases in which there is paralysis of one of the lower extremities, it has been taught that it arises from disease of the corpus striatum. On the anterior lobe the following case is given by Serres. “ A woman, forty years of age, had an attack of apoplexy, from which she recovered with the left leg in a state of complete paralysis, and the left arm admitting of a slight degree of motion.” Here was a case of lesion of both the upper and lower extremity of the same side, but in the former the paralysis was par- tial, in the latter complete. On dissection, it was found that two circumscribed abscesses existed in the substance of the right hemi- sphere, the larger situated in the corpus striatum, the smaller in the optic thalamus. Another case is given of a patient who got para- lysis of the side ; the muscular power of the arm being completely destroyed, while the leg retained a considerable degree of motion. In this case the corpus striatum was but slightly affected, while nearly the whole substance of the optic thalamus was destroyed. I have also to remark, that Serres performed similar experiments on the corpus striatum in dogs, and came to the conclusion, that it governs the motions of the lower extremities. The structure, extent, and special action of the corpus striatum and optic thala- mus, are said to afford some explanation why, in ordinary cases of paralysis, the arm is more often affected than the leg, and does not recover so soon. The fact of the prolongations of the optic thalami being much more complicated and extensive than those of the cor- pora striata, is thought to explain their greater liability to disease. There are, however, not unfrequent exceptions to this law; and it is not uncommon to meet with cases which militate against the doctrines laid down by Serres, and other pathologists, particularly so far as regards the connection between the corpora striata and the government of the lower extremities, so that I would have you look upon it as a point by no means fully established. The latest observations on this subject are by Andral, who brings forward many facts opposed to the opinions of Serres, Foville, &c. &c. Out of seventy-five cases of accurately circumscribed disease of the brain, the disease being hemorrhagic, or otherwise, he found that, in forty, where the paralysis existed in both extremities of one side, there were twenty in which nothing was injured but the anterior lobe, or the corpus striatum; while in nineteen the lesion existed in the posterior lobe, or the optic thalamus. In these seventy-five cases, also, were twenty-three in which one arm was paralysed. In these, eleven presented the disease in the anterior lobe, or in the corpus striatum ; ten in the optic thalamus, or posterior lobe ; and two in the middle lobe. Finally, out of these cases were twelve of paralysis of one arm; ten of these presented disease in the corpus 213 ENCEPHALITIS. striatum, or anterior lobe; and two only with disease in the optic thalamus, or in the posterior lobe. These facts prove how uncertain the matter is yet. It would appear that when a simultaneous and equal injury of both corpora striata and optic thalami exists, it would be natural to expect com- plete paralysis of one side, and I believe there are some cases on record in support of this opinion. But when you have paralysis affecting both sides of the body, you are not to suppose that there is necessarily an affection of the corpora striata and optic thalami, for such symptoms, in the majority of cases, are found to depend upon either an intense congestion of the brain, or a large serous, or sanguineous effusion. The same phenomena are produced by the pressure exercised by the diseased on the sound hemisphere, in a case of local encephalitis, or by disease affecting the upper part of the spinal cord. With respect to disease of the cerebellum, the only means of determining its affections consists in first considering the seat of the pain, if any, and, in the next place, the effect on the genital system. There are a great number of cases detailed in various treatises in proof of the close connection between the cerebellum and the genital function. I shall relate a few of these. A man, aged thirty-two, got an attack of apoplexy, followed by violent erection of the penis, which continued until death; here we have a case of apoplexy accompanied by priapism. On dissection, the whole of the cerebrum was found healthy; but there was an apoplectic effusion in the middle lobe of the cerebellum. Another case is given of a man, aged fifty-five, who died of apo- plexy in a brothel, and who, after the attack, had violent priapism. On dissection, the substance of the cerebellum was found to be extensively destroyed, and there was an apoplectic effusion in the fourth ventricle. There is a remarkable case on record of a pros- titute, in whom the clitoris was extirpated, as it was considered that it was the irritation of that organ which brought on a pernicious habit, by which her health was greatly impaired; and it was con- ceived that, as soon as the supposed source of excitability was got rid of, she would give up her vicious propensity, and be restored to health. But in this instance it is probable that the effect was taken for the cause; for on her death, which took place some time after, the cerebellum was found to contain a number of chronic abscesses. Serres gives the case of a woman, who died of an apoplectic effusion into the cerebellum. During the fit, she had hemorrhage from the uterus; and, on examining that organ after death, a large clot of blood was found within its cavity, and the broad ligaments, ovaries, and, in fact, every part of the generative apparatus, were in a state of high vascularity. Yet this female was seventy years of age, and her menses had ceased at the usual period. There is a most important case bearing on this point on record. A gentleman, who was subject to constant and distressing nocturnal emissions, consulted his physicians, who, considering them to be the result of debility, prescribed various tonic and 214 STOKES’S THEORY AND PRACTICE OF MEDICINE. stimulant remedies. He used various preparations of iron, bark, camphor, opium, hyosciamus, nitric acid, and many other things of a similar kind, but without advantage. Prom the fact of the failure of all these remedies, and the circumstance of his having complained of an occasional sense of uneasiness in the back of the head, his physician was led to think that his symptoms might have some connection with an excited condition of the cerebellum; and, under this impression, had the back of the head shaved, leeched, and covered with a quantity of pounded ice. From this time his symptoms began to decline rapidly, and in a fortnight he teas quite free from complaint. Now, this case, taken singly, would prove very little; but when we view it in connection with the number of cases in which disease of the cerebellum has been known to be followed by excitement of the genital organs, it becomes of considerable importance. I have now seen two cases in which this connection was observed. In the case of a young man, who was brought into the Meath Hospital some time ago with paraplegia, it was observed that the penis was in a state of constant erection, and there were continual seminal emissions. On dissec- tion, an effusion of blood was found in the cerebellum, and another in the hemisphere opposite the paralysed side. There was another case of a patient who was attacked with apoplexy and paralysis of one side, but with the unparalysed hand he continued to attempt the act of masturbation, so that it was necessary to tie down his hand. On dissection, there were several effusions in the substance of the cerebellum. All these facts strongly go to prove the connec- tion which subsists between the cerebellum and the generative function; and I think it would not be unsafe to make the diagnosis of disease of that organ in cases of cerebral disease, where the genital system was much excited.1 ‘A case of this kind was published by the editor some years ago, which has been cited as a case of meningitis of the cerebellum, by Di. Abercrombie. A boy, aged five, pale and delicate, after having been slightly indisposed for four or five days, was seized, on the 9th of August, with violent convulsions. On the 10th, there was fever with delirium; a vacant look of the eye, and an evident imperfection of vision, which appeared by his attempting to lay hold of objects that were presented to him, and missing them; the pupil was dilated, and there was slight strabismus. On the 11th, 12th, 13th, and 14th, the symptoms gradually increased. On the 15th, coma ; constant mo- tion of the right arm and leg; the left appearing to be paralysed. In the night, he was seized with violent convulsions, which continued till his death, which took place on the morning of the 16th. On dissection, the brain was found healthy. There was remarkable vascularity on the tuber annulare, forming a thick web of vessels. This was connected with the arachnoid coat of the right side of the cerebellum, which was thickened, with some deposition of coagulable lymph. About four ounces of fluid was found at the base of the skull, but not above a tea-spoonful in the ventricles. An important point in this case, which Dr. Abercrombie appears to have overlooked, was the connection between the state of the cerebellum and the genital functions; the latter being much excited, and the penis in an almost constant state of erection. See “ Case of Arachnitis Cerebelli, by Robley Dunglison, &c. &c.,” in the “ London Medical Repository,” for October, 1822; and Abercrombie “On Diseases of the Brain,” 3d edit., Lond., 1836. p. 60.—/?.

Symptoms of encephalitis—Conclusions as to contraction and paralysis—Remarkable cases of encephalitis—Abscesses in the brain—Sympathetic affections—Enteritis simulating cerebritis—Prognosis in cerebritis—Remote neuralgia a symptom. To-day we again take up the subject of encephalitis; and allow me here to observe on the extraordinary variety and complication of the symptoms of this disease. Unless you study with extreme care a great number of separate cases of cerebral disease, you will never be able to get clear ideas on the nature of this affection, so peculiarly interesting to the pathologist, and the practical physician. More circumstances seem to combine in creating a variety in the symptoms of cerebral affections than in those of any other viscus of the body. We have in the case of cerebral disease all the variety of symptoms depending on the peculiarity of the part engaged, on the complication of local encephalitis with arachnitis, on the results of pressure, the nature and extent of effusions, the difficulty created by the phenomena of neurosis, and many other circumstances. At my two last lectures I drew your attention to some cases of local encephalitis, in which the disease was pointed out by certain affections of the muscular and generative systems. There are several other circumstances connected with this part of the subject, which are also deserving of attention, and it is necessary that you should be aware that there are other sources of diagnosis in cases of local encephalitis besides those already mentioned. There is no doubt, that though in many cases the occurrence of contraction, spasms, and pain in the extremities, precedes that of paralysis, yet we may have paralysis from local cerebritis coming on without these 'precursory signs, and as suddenly as in cases of apoplectic effusion. This important fact you must never lose sight of. Of this I have now seen several instances. I recollect a remark- able case of a man who had been bled in the cold stage of an ague, with the effect of stopping the intermittent. In a few days symptoms of pneumonia set in with great prostration of strength. These were followed by signs of disease of the brain, which were that the patient became suddenly nearly insensible, and on that day was observed to have his hand constantly placed on the right side of the head. Next day, without any preceding spasms or contractions being observed, he was found paralytic in the left upper and lower extremities, with paralysis of the left sterno-mastoid, and loss of sight in the left eye. On dissection we found softening of the two anterior thirds of the right hemisphere, which were of the consist- ence of thick cream. The disease engaged the corpus striatum, but the optic thalamus was healthy. Another remarkable instance occurred lately in a person labour- ing under aneurism of the innominata and hemiplegia. Here the paralysis came on suddenly, and its cause was found to be an 216 STOKES’S THEORY AND PRACTICE OP MEDICINE. abscess of the brain. I must observe, however, that there were some precursory signs in this case, though contraction and spasms were not observed. The patient had violent headache, and was subject for some time to occasional numbness and pain in the affected arm. I repeat it, you may have the greatest variety in the succession and combinations of the symptoms of this disease, and this observ- ation applies to the lesion of muscular motion, sensation, the state of the intelligence, and the organic functions. You must study numerous cases to get an accurate idea of this disease. I would advise you to examine the writings of Lallemand, Bouillaud, Aber- crombie, and Serres, on this subject, and then consult the last edi- tion of Andral’s Clinique Medicate, where you will find the value of the symptoms discussed in a most impartial and philosophical man- ner. In this splendid work you will find many cases of cerebritis, in which the symptom of spasm and alternate flexions and extensions was wanting. Indeed he looks upon it as a symptom which cannot yet be called pathognomonic. We may, I think, come to the following conclusions on this subject:— 1st. That local encephalitis is often accompanied by various forms of muscular contraction in the parts afterwards to be para- lysed. 2d. That in some cases the paralysis is not preceded by muscular contraction, though various lesions of sensibility may occur. 3d. That the paralysis may be gradual, (which is the most common case,) or sudden. 4th. That the contraction may be intermittent, periods more or less elapsing when the symptom is absent. 5th. That in general the contractions occur in the first, the para- lysis in the second stage. 6th. That in a few cases the reverse occurs. 7th. That in some cases, general or partial convulsions, and in others, tetanic symptoms, precede the paralysis. You will see in the Gazette Medicale, for October, 1833, the particulars of a most interesting case, recorded by Berard, jun., of fungous tumours of the dura mater, which was not accompanied by any alteration of muscular motion. This was removed, with the adhering portion of the dura mater, when the patient was attacked, for the first time, with loss of consciousness and convul- sions of the trunk and extremities. The operator, justly concluding that the sudden removal of the partial resistance of the brain was the cause of the symptoms, applied a piece of agaric to the denuded surface, and made gentle pressure upon it, when he found that immediately the convulsions ceased, and the intelligence was re- stored. Thus, gentlemen, does disease often become a second nature, and its want is the cause of symptoms. As far as we see of the brain, this pathological fact appears cer- tain, that injuries of the upper part of that organ are accompanied by more marked and distressing symptoms than similar lesions of ENCEPHALITIS. 217 the lower part. There seems, indeed, to be a decided difference between the sensibility of the superior and inferior parts of the brain. The great proportion of those cases in which there was extensive latent disease of the brain, have been cases in which disease predominated in or towards the inferior surface of that organ. In this situation it has been proved by numerous examples that you may have extensive disease without those symptoms of muscular or mental derangement, which ordinarily characterise inflammatory affections of the brain. I recollect the case of a patient who was brought into our wards complaining of feverish symptoms, with pain of the left temple, extending to the eye of the same side. With the exception of this pain, he had no cerebral symptoms of any kind ; his intellect was sound, and he was quite free from muscular pain, rigidity, spasms, or paralysis. He was ordered to take some opening medicine, and to have leeches applied over the seat of the pain, but derived no benefit whatever from their application. This led me to suspect that something unusual was going on, and more particularly when I observed that the leeches were repeated without any decided benefit. One morning on going into the ward I looked about for him for some time to no purpose ; in fact, his countenance was so altered that I could no longer recognise him. During the night, the globe of the eye was almost suddenly thrust forward by an enormous oedema of the soft parts of the orbit, and the pain became excruciating. It was then con- ceived that the pain complained of on admission was the result of disease of the bones of the orbit, and that abscess had formed behind the eyeball. Under this impression, and in accordance with the earnest request of the poor sufferer, it was determined to make an incision to give exit to the confined pus. A curved bistoury was cautiously though deeply introduced over the eyeball, but on with- drawing it, only a small quantity of serum escaped. The swelling went on increasing, and the eyeball was pushed forward so as to be raised above the level of the nose. A curved bistoury was then carried extensively round the orbit, but without giving exit to any matter. Under these circumstances, I came to the conclusion that it was an example of deep-seated abscess of the brain, with symp- tomatic cedema of the orbit. This oedema of superficial parts, in cases of deep-seated disease, is, you know, a thing of common occurrence, and may be observed in many instances of hepatic abscess, acute pleuritis, and other inflammations. In fact, there is such a remarkable sympathy between deep-seated parts and the integuments over them, that you may have this cedema in deep- seated inflammations of the organ. The patient now became gradually worse, his agony was intolerable, and the protrusion continued undiminished, but he had not either delirium or convul- sions. He sank into a state of profound coma, in which he remained for about twenty-four hours, when death put a period to his sufferings. On dissection, there was no pus found in the orbit, and its bones were healthy, but in the inferior part of the 218 STOKES’S THEORY AND PRACTICE OF MEDICINE. anterior lobe of the brain there was an abscess about the size of a large walnut, resting on the cerebral surface of the orbit. I have since learned from several of my friends that they have witnessed cases of the same description. It is an interesting disease, and one which you should be acquainted with. I think the existence of the following symptoms should lead you to suspect it. First, pain in the head, preceding the appearance of tumour of the orbit, and this pain not affecting the orbit itself; for observe, in this case the pain was referred to the temple and hot to the orbit. The next thing is the pain resisting ordinary treatment, and being followed by a sudden cedema of the parts within the orbit, and protrusions of the eyeball. These two circumstances, when occurring in conjunction should, I think, lead you to suspect acute internal disease. Again, in those cases where abscess supervenes on caries of the internal table of the bones of the cranium, the affection is much more chronic than in this or similar instances of deep-seated abscess of the brain. With respect to this remarkable symptom of local inflammation of the brain, this external cedema, I shall relate the history of another case, as I am anxious to throw as much light as possible on this obscure subject. It may appear strange, that when a dense bony plate and an extremely strong membrane (besides other parts) intervene between the integuments and the seat of disease, that local oedema of external parts should take place as a consequence of internal inflammation. Strange however as it appears, it is true, and the intervention of the skull does not prevent it, as will be seen by the following case. A boy was admitted into the Meath Hospital, complaining of severe pain in the situation of the mastoid process. He was of a scrofulous habit, and had for a length of time a discharge of matter from both ears, with slight loss of hearing. Some time before his admission the discharge had been very copious, but on being- exposed to cold it was diminished in quantity, and he immediately was attacked with severe pain behind one of his ears. When he came into the hospital he was screaming with agony, but had no delirium, and the muscular system was unaffected. But what was chiefly remarkable in this case was, that, on the second day after admission, a distinct tumour formed in the upper portion of the neck, about an inch and a half behind the mastoid process. So distinct indeed was it, that it was generally believed that the disease was periostitis of the base of the skull, which had run on to suppu- ration. An incision was made over the tumour, and the knife was carried down to the bone, but no matter could be discovered. The patient then became gradually worse, the pain was dreadful, but there were no convulsions. Shortly before death he had a few slight muscular twitches, with delirium, and died in great agony. During the whole course of the disease, the discharge from the ear had continued and was remarkable for its fetor. On examining the brain, we found neither abscess nor arachnitis. On slitting up the longitudinal sinus, a remarkable fetid odour was perceived, ENCEPHALITIS. 219 which increased as the incision was prolonged in the direction of the left lateral sinus. Here there was a quantity of extremely fetid matter, of an almost cheesy consistence, and mixed with blood; and a communication was discovered between it and the internal ear, the bones of which were carious, and its cavity filled with the same kind of pus. Here we have a curious example of oedema of the external parts depending on deep-seated disease. I shall now relate the particulars of a case in which, although the symptoms of an affection of the brain were better marked than in the foregoing, still they were by no means so decided as one would have expected from the appearances revealed by dissection. A patient was brought into the Meath Hospital, with symptoms which were thought to be those which mark the ordinary form of delirium tremens. The man had been a great drunkard, but for some time back had given up the use of ardent spirits. He com- plained of severe and constant pain of the ear, which he stated to be of twelve weeks’ standing, and that it was this which first induced him to give up drinking, as he found that it was always aggravated by the use of spirits. On admission, he appeared to labour under a highly excited state of the nervous system; he had general tremours, and was incapable of keeping up a connected conversation, though he could answer a few questions accurately. Here we observe a remarkable difference between this and the last case detailed, in which there was not the slightest evidence of any lesion of the intellectual powers. In the present case, the symp- toms were pain, tremours, and incapability of supporting a rational conversation, but no decided constitutional symptoms. The pain, which had never abated since its commencement, became now violently exacerbated, he moaned frequently, and kept his hand constantly applied to the affected side of the head. To this last symptom I beg leave to direct your attention, as it is an exceedingly common one in cases of local inflammation of the brain. After a few days the mouth was drawn slightly towards the affected side, and it was found that the tongue was protruded in the opposite direction. Symptoms of fatuity now became more distinct, followed by coma, and the patient sank. During the whole course of the disease he had no spasms or paralysis of any of the limbs. On dissection, there was a circumscribed abscess found in the substance of the middle lobe of the brain. The abscess itself was encysted, but the substance of the brain round it was soft, particularly at its inferior part, where it was found to be connected with a carious state of the squamous portion of the temporal bone. There was a considerable degree of softening in that part of the brain which lay between the abscess and the corpus striatum. Here we have a case in which pain of the ear is chiefly complained of; but, in addition to this, it was observed that the patient could not sustain a connected con- versation, that there was some fatuity, that the mouth was drawn to one side, and that coma came on before death. Under such circumstances there could be less hesitation in pronouncing the disease to be an affection of the brain; and accordingly we find, on 220 STOKES’S THEORY AND PRACTICE OF MEDICINE. dissection, unequivocal marks of disease of the middle lobe, in addition to the caries of the temporal bone. I might detail many cases of a similar kind, without being under any apprehension that I should be occupying your time to no pur- pose, for the recital of such cases is better calculated to convey information on this obscure subject than any lecture. I shall, however, content myself with one or two more. A man, addicted to the use of ardent spirits, was brought into the surgical wards of the Meath Hospital in a state bordering on coma. It was thought at first that he was labouring under typhus fever, and, under this impression, no particular attention was paid to the cerebral symp- toms for the first day or two. At the end of this period, it was learned that he had fallen in going up stairs, while in a state of intoxication. His head was shaved, but no signs of wound or contusion discovered, though his friends persisted still in their statement that he had fallen while intoxicated and hurt his head. When admitted into my wards he appeared moribund; his pulse was imperceptible at the wrist, he had extreme coldness of the limbs, and a disposition to the formation of gangrenous spots about the ankles. He was in a state of stupor; but when roused answered questions tolerably well, and said that he had no pain in his head. The remarkable feature however in this case, was a great degree of muscular rigidity, affecting all the extremities. The fore-arm was flexed, and he had not the power of extending it. The penis was in a state of permanent semi-erection, but there were no seminal emissions. Here was a case in which, taking all cir- cumstances into consideration, the cause of the disease seemed to be in the brain. He had been drunk, and was supposed to have got a fall while in that state ; he was comatose, from which, how- ever, he could be roused ; and he had rigidity of the limbs, with erection of the penis. With this view I came to the determination of treating it as a case of general inflammation of the substance of the brain. I concluded that there was no arachnitis, from the fact of his answering correctly when roused, while I felt convinced that if there was not actual inflammation of the substance of the brain, there was at least very intense and general irritation. The treat- ment in this case was successful. After warming the extremities by wrapping them in flannel, and the use of artificial heat, the head was shaved, a large number of leeches applied, and an ice cap ordered to be worn constantly. The leeching was repeated, and he used the ice cap for four days. On the second day after this plan of treatment had been entered upon, there was some improve- ment, but on the following day the accuracy of our diagnosis of inflammation of the brain appeared, for the patient had violent spasms of the right arm and leg. These however subsided, the coma, rigidity, and other symptoms also disappeared, and the patient slowly but perfectly recovered. In addition to the means of treatment already detailed, the patient’s system was placed under the influence of mercury. A question might arise as to the exact nature of this case. Was ENCEPHALITIS. 221 it a case of actual inflammation of the substance of the brain, or was it mere sympathetic irritation produced by some other disease? It may be said that it was a case of gastro-enteritis, with a sympa- thetic affection of the head. It certainly might be so, but the great probability is, that it was not; because such symptoms as were ex- hibited in this instance are very rarely the result of gastro-enteritis; and if it was a gastro-enteritis, it is not likely that such complete success should have followed treatment directed to the head. These circumstances make it likely that it was general irritation or inflammation of the substance of the brain itself; and, if so, the case strongly illustrates the utility of mercury, leeching, and cold applications in the reduction of encephalitis. The man was brought into the hospital in a dying state, and recovered under the influence of physiological treatment. While I am on this part of the subject, namely, the possibility of the head being sympathetically engaged in some instances to a very remarkable degree, I may say that the following conclusions on this point seem to be fairly drawn. That when an affection of this kind depends upon a gastro-enteritis, the signs of cerebral irritation are general rather than local. In children who are labouring under apparent symptoms of cerebral affection, it has been long known that the irritation of the brain may depend on a variety of causes. In adults, too, the symptoms of cerebral irritation may be the result of various affections, of gastro-enteritis, worms in the intestinal canal, hysteria, hypochondriasis, and many other diseases. In most of these cases, however, particularly with respect to chil- dren, the symptoms are general, being pain, delirium, coma, and convulsions on both sides. But we very seldom witness the occurrence of symptoms of local irritation of the brain as produced by sympathy with some other disease, though it is a fact that they may occur occasionally, and without our being able, after death, to discover any existing local encephalitis. A young female was admitted into one of the surgical wards of the Meath Hospital for some injury of a trivial nature. While in hospital she got feverish symptoms, which were treated with purgatives, consisting of calo- mel, jalap, and the black bottle, a remedy which deserves the name of the coffin bottle, perhaps better than the pectoral mixture so liberally dealt out in our dispensaries as a cure for all cases of pulmonary disease. She was violently purged, the symptoms of fever subsided, and she was discharged. A few days afterwards her mother applied to have her readmitted, and she was brought in again and placed in one of the medical wards. Her state on admis- sion was as follows:—she had fever, pain in the head, violent contraction of the fingers, and alternate contractions and flexions of the wrist and fore-arm. These muscular spasms were so great that the strongest man could scarcely control the motions of the left fore-arm. In addition to these symptoms, she had slight thirst, some diarrhoea, but no abdominal tenderness. On this occasion a double plan of treatment was pursued; the therapeutic means being directed to the head, in consequence of the marked symptoms of 222 STOKES’S THEORY AND PRACTICE OF MEDICINE. local disease of the brain, and to the belly, from the circumstances of abdominal derangement observed in this and in her former illness. She died shortly after with violent spasms of the hand and fore-arm; and as she had presented all the ordinary symptoms of a local inflammation of the opposite side of the brain, we natu- rally looked there first for the seat of the disease. After a careful examination, however, no perceptible trace of disease could be found in the substance of the brain, which appeared all throughout remarkably healthy. She had all the symptoms which, according to Serres and Foville, would indicate disease of the optic thalamus, or the posterior lobe of the opposite side, yet we could not find any lesion whatever of its substance after the most careful examination. But on opening the abdomen we found evident marks of disease; the lower third of the ileum, for the length of six or eight inches, was one unbroken sheet of recent ulcerations. This case I look upon as a very singular one, showing that we may have well- marked symptoms of a local irritation of the brain depending on a sympathetic cause. It is fortunate, however, for the study of me- dicine, that such cases form the exception and not the rule. I may remark here on the latency of the enteritis as to the pain. There was no abdominal tenderness, a fact illustrative of the great law which so particularly applies to gastro-enteric disease, that when the sympathetic affections are prominent, the usual or local symp- toms are proportionally latent. With respect to the prognosis in cases of local encephalitis, the following conclusions seem to be well grounded. As a general rule, the prognosis is to be unfavourable, from the nature of the organ, its importance to life, and the frequent complicated and obscure nature of cerebral affections. In local encephalitis you have always two things to apprehend—the acuteness of the disease, and its subsequent effects. The patient may die of acute inflam- mation, or, if you control this, of the chronic disorganisation which frequently supervenes, terminating in apoplexy, paralysis, and other consequences. On the other hand, it is consolatory to reflect that experience has proved the possibility of curing both general and local inflammation of the brain. There are numerous cases on record in proof of the success of well-directed treatment. The annals of surgical science are filled with cases of extensive injury of the brain successfully treated; and it is equally true, that medi- cine can exhibit many instances of well-marked idiopathic inflam- mation of the brain brought to a favourable termination. In making our prognosis on a case of local encephalitis, much will depend upon the extent to which the muscular system is affected. Spasm of one extremity is more favourable than spasm of both; and an affection of the muscles of the face is not so unfavourable as of those of the extremities. The next thing to be considered is the age of the patient. In the very young, and in persons advanced in life, our prognosis is not to be so good as in the case of one removed from these extremes, as neither of the former admit of such active treatment; but of the two, it is better to have to manage the disease ENCEPHALITIS. 223 in a child. It is also singular how well children will often bear active treatment. There is another point which should not be omitted. There are, in some cases of local inflammation of the brain, muscular contrac- tions and extensions, alternating with a state of rigidity, while in other cases the rigidity is permanent. It is not easy to say which of these cases is the worst, but I believe that the most unfavourable are those in which we have chiefly violent contractions and ex- tensions. Again; with respect to the cessation of the spasms, it may be considered either as a favourable or a most unfavourable symptom. The circumstance of the cessation of the spasms must have been produced by some modification in the state of the cerebral affection. If it be accompanied by a return of the power of trans- mitting proper motion to the affected limb, it is then a sign of great value, as showing that the cerebral irritation is nearly gone. But if the spasms subside, in consequence of the supervention of reso- lution arid paralysis, then the cessation is a symptom of a most unfavourable kind, as showing that actual disorganisation has taken place, which seems to be incurable. It may be necessary to remind you that if the patient has, com- bined with these spasms, alternations of delirium and coma, it affords grounds for making a bad prognosis, as such symptoms indicate that the inflammation has extended to the periphery of the brain, and the arachnoid membrane. The state of the intellect is also a matter of importance; the more intact and undisturbed it is, the greater is the chance that the affection of the brain is confined within a small compass. Here, however, I am anxious to impress this upon your minds, that the absence of delirium should not mislead you, or induce you to form any favourable conclusions on that account alone, in cases of encephalitis, for it is a fact that we may have extensive and fatal disease of the substance of the brain without delirium. I need not tell you that convulsions, or para- lysis of one side, do not indicate so unfavourable a prognosis as where both sides are engaged. Lastly, you should bear in mind that cases of inflammation of the substance of the brain are very subject to relapse. All these circumstances should be taken into account, and a favourable prognosis should be always formed with a great deal of caution. I alluded in a late lecture to the occurrence of pain in some par- ticular part of the extremities, as a premonitory sign of this disease. A remarkable case, bearing on this point, has come to my knowledge, and I think I cannot better employ the remaining part of our time than in giving a brief abstract of it. A lady got a pain in the lower part of the tendo Achillis, which was considered to be rheumatic, and very little notice taken of it. There was no swelling, heat, or tenderness on pressure, in the painful part, and the nature of the disease was so imperfectly understood that all the efforts of her medical attendants were directed to the heel, but without any benefit whatever. Matters remained in this state for some time, when she was suddenly attacked with convulsions and coma, and died. On 224 STOKES’S THEORY AND PRACTICE OF MEDICINE. opening the head some hours after her demise, a large abscess, together with an apoplectic effusion, was found to exist in the opposite hemisphere of the brain. There are various other exam- ples of a similar kind. I have no doubt that many of those anomalous pains are frequently connected with incipient disease of the brain. I know the case of a gentleman, labouring under a painful affection of the face, which had got the name of tic doulour- eux, and had been subjected to all the variety of treatment which persons labouring under that affection so commonly undergo. But it has since been proved that his complaint is by no means analo- gous to what has been termed tic douloureux, for it has been most successfully treated by shaving the head, and applying leeches and an iced cap over the seat of the suspected irritation. At present, whenever an attack comes on, he immediately gets a bladder, con- taining a quantity of pounded ice, applies it to his head, and in this way obtains relief. This shows that the severe pain in his case, which many would confound with a local affection of the nerves of the face, is decidedly the result of a morbid sensibility of the cerebro- spinal centre, LECTURE XXVI.

We have now to enter upon the treatment of inflammation of the brain ; and you will find that a knowledge of the general principles of the treatment of cerebral inflammation will be quite sufficient to guide you, even in the management of cases which present apparent exceptions to the ordinary symptoms. The truth is, that the prin- ciples which should regulate the treatment of inflammation of the brain are nearly the same in all cases. I shall commence with the treatment of the acute form in the adult. Acute phrenitis in the adult is an exceedingly severe dis- ease, characterised in its first period by an high exaltation of the functions of the brain, and in its second by a corresponding de- pression. In this form of disease we have generally high fever, a strong bounding pulse, throbbing of the carotids, intense pain of the head, great brilliancy of the eye, with intolerance of light, vivid redness of the face, a ferocious countenance, and furious delirium. Under such circumstances there is no time to be lost; the brain is a delicate organ, and cannot bear much disease, and its powers of ENCEPHALITIS. 225 recovering from idiopathic disorganisation seem much less than those of the lungs or abdominal viscera. Indeed, we must believe that, notwithstanding the assertions of Lallemand, it remains to be proved that recovery can take place after the stage of softening has set in, in idiopathic encephalitis. The brain differs from the lungs or digestive organs in having no excretory duct for the products of inflammation, and hence one cause of the greater danger of its idio- pathic inflammations than its traumatic, where an opening is formed in the skull. In such a case you have to apprehend two patholo- gical lesions, the inflammatory softening of the substance of the brain, and the inflammation of its serous membranes, with effusion into their cavities. The patient, too, may die from congestion, or even an apoplectic effusion may occur, illustrative of the proposi- tion of Broussais, that all encephalic irritations may produce an apoplexy. I have seen this termination, even in the infant under a year old ; in such a case I once saw an apoplectic effusion which had supervened in the course of an arachno-cerebritis, and which amounted to several ounces of blood. Every moment is precious, and no consideration should induce you to put off, even for an hour, the adoption of the most rigorous measures. In the first place, you must bleed; and here let me remark that blood-letting should be performed so as to make a decided impression on the symptoms. It will often happen, that, from the state of uncontrollable fury which the patient is in, it is dangerous and almost impossible to bleed him. Here you must endeavour to moderate the delirium, and there is no way by which you can accomplish your purpose so fully as by cold dashing. Where there is high delirium, I believe you will always find it the best plan to precede venesection by throwing a few basins of cold water over your patient’s head. This will procure an interval of comparative tranquillity, during which you can open either a vein or an artery with convenience and safety. Of course, if any thing like collapse ensues (which is possible) you will not bleed immediately. The object of the cold pouring, under these circumstances, is to obtain such a diminution of the fury as will allow of your bleeding the patient with safety, as to the operation. If you cannot reduce the cerebral excitement by this means, it will then be necessary to put on the strait waist- coat, pro tempore. There is a difference of opinion among medical men with respect to the mode of abstracting blood ; some prefer taking it from the arm, some from the jugular vein, and some from the temporal artery. Now, I am inclined to think that it is better to open a vein in the arm, and that venesection performed in this way will be found to answer every purpose. It is said that if you take blood from the temporal artery or jugular vein, you deplete the brain more directly than you would by opening one of the brachial veins. This may be true, though I think it still remains to be proved that the drawing of a smaller quantity of blood from these vessels will have a more powerful effect on the system than from the arm. If you open the temporal artery, there are two disagreeable circumstances which you should be prepared to meet. 226 STOKES’S THEORY AND PRACTICE OP MEDICINE. In the first place, the patient is in a state of furious delirium, you don’t know how long this may last, and it may happen that in one of his paroxysms he will tear off the bandage, and, if not watched, bleed to death. A case of this kind occurred not long since in the person of a gentleman of this city, who had the temporal artery opened. He tore off the bandage, and a terrible hemorrhage ensued; assistance was procured, and the bandage re-adjusted; he tore it off a second time, and died shortly after, his death being evidently accelerated if not actually caused by the quantity of blood lost. Again, it is possible that an aneurism may be formed as a consequence of the operation, which may excite a determination to the head, and tend to keep the patient in a state of excitement. Thirdly, you must employ a bandage to secure the artery, and to this there is a strong objection, in consequence of the pressure which it makes on the external vessels of the head. I am there- fore strongly opposed to opening the temporal artery in cases of acute inflammation of the brain, accompanied by high mental or muscular excitement. Now, with respect to the jugular vein, you are aware that to command this vessel pressure is also required. How this pressure can be made without interfering with respiration and compressing the veins of the neck, so as to add to the existing congestion of the head, I am at a loss to know. I would advise you, therefore, when you bleed in phrenitis, to prefer opening a vein in the arm ; by making a free incision you can draw blood in such a way as to make an impression on the system, fully equal to that produced by either of the foregoing modes ; and without sub- jecting your patient to the same degree of inconvenience or risk. The quantity of blood to be taken away must be regulated by the age, strength, and constitution of the patient, as also by the intensity of the disease. Where you have to deal with a young man of robust constitution, your first bleeding may amount to thirty ounces. You will often find it difficult to produce fainting in this disease, for the excited condition of the brain keeps up a constant determination to that organ, and prevents syncope. The same difficulty is met with in cases of hypertrophy of the left ventricle, which causes a great determination to the head. Your next step is to have the head shaved. Never omit this. The very circumstance of freeing the head from the covering of hair, and permitting the free contact of air with the scalp is of advantage ; and if you wish to employ cold applications, you can- not do so properly without premising this operation. After you have done this, you should apply a large number of leeches to the scalp, or if you cannot readily procure leeches, employ instead of them light scarifications to the temples and nape of the neck, and keep on the cupping-glasses until you have obtained a sufficient quantity of blood. By acting in this way with promptness and decision, you arrest the violent symptoms and gain time. In treating a case of this kind it is a very common practice to use cold applications. They are for the most part applied in shape of a cold lotion to the head, but I need not tell you that this is a 227 ENCEPHALITIS. very imperfect mode of using them, and indeed I have seen but very few persons who were acquainted with the proper mode. Persons are in the habit of supposing that the mixture of a certain quantity of saline ingredients with water should produce a very cold lotion, and so it does indeed while the salts are dissolving; but as soon as this is accomplished, the mixture rapidly acquires the temperature of the surrounding air. The solution is generally prepared by the apothecary, (and sent in a bottle, as if they could cork up the cold,) but the cold is quickly lost, and, in a few moments after the lotion has been applied, you will find it tepid, and passing into a state of vapour. Now if you wish to derive any benefit from the use of cold applications, you must stand by yourself, and see the thing properly done. The object is to have the scalp kept con- stantly cold, and this can be done only by the repeated application of cold lotions. If you prefer saline lotions, you should have them made by the bedside, and applied while in the act of solution, or you should put a quantity of ice into your lotion, for while a single piece of the ice remains undissolved, the temperature of the lotion will be very little above the freezing point. A very good way is to have a jar of cold water with a quantity of ice in it, and to apply cloths dipped in it every minute, taking care not to immerse the hot cloth into the iced water until it has been wrung out in another vessel of water. You may also use the ice cap, though this is a painful remedy. But the mode of using ice to the head, which I prefer in all cases, and particularly in that of the child, is to take a piece of smooth ice, about the size of a dollar, and half an inch thick; this is to be placed in the hollow of a fine cup sponge, and steadily moved over the whole shaved scalp. By this mode you prevent the pain which the iced cap produces, and the sponge absorbs the water produced by melting, and the application may be continued for an indefinite length of time. But one of the best modes of applying cold to the head is that recommended by Dr. Abercrombie, and, as far as my experience goes, I can safely affirm that there is scarcely any remedy of such unequivocal value in acute inflammation of the brain or its membranes. Dr. Abercrom- bie’s mode is this—the scalp being first shaved, you direct the patient’s head to be held over a basin, and then taking a jug of cold water, pour its contents over the head from some height in a small continuous stream. This measure, simple as it may appear, is one of extraordinary efficacy. In fact, so great and instantaneous is the depression of the vital power produced by this mode, that it must be used with caution. There are numerous cases of persons in the highest state of maniacal excitement, reduced in a few mo- ments to a low and weak state by this powerful remedy. There are also instances of its rapidly depressing effect in the early stages of acute hydrocephalus. I have used it more in the phrenitis of adults than in the hydrocephalus of children; but in the latter disease I know many instances of its value, and believe it to be only second- ary to the application of leeches. In acute inflammation this form of cold effusion should be employed every hour or half hour, 228 STOKES’S THEORY AND PRACTICE OP MEDICINE. according to circumstances, and if you wish to increase its efficacy you can do it by placing the patient’s feet in warm water at the time of its application. Here, then, gentlemen, is the first set of remedies you should employ in a case of acute phrenitis; a full bleeding from the arm, premising it, if there be great maniacal excitement, by dashing a basin of water over the patient’s head; shaving the head, and applying a large number of leeches, or if these are not within reach, the use of cupping; and, lastly, the constant application of cold lotions, or the use of the cold affusion after the manner employed by Dr. Abercrombie. These are the great measures which should be boldly and promptly put in prac- tice, in order to counteract the first violence of a case of acute inflammation of the brain. You will next act upon the bowels by purgatives. This is a matter of the deepest importance, for there is hardly a disease in which the judicious administration of purgatives has been followed by more decidedly beneficial effects, than in inflammation of the brain, where the digestive tube has been in a healthy condition. Purgatives are also found to be of great benefit in the simple hydrocephalus of children, and in several cases it has been observed that the disease did not yield even after active bleeding, until purgation had been employed. Dr. Abercrombie speaks in the highest terms of the value of purgatives, even after coma has set in. The purgatives which are generally used are those of the drastic kind, and they may be given by the mouth or in the form of enemata. Such are the rules for the treatment of the ordinary form of acute encephalitis. I shall now make a few observations with respect to the local applications. It may not be necessary to repeat the vene- section, particularly if the means which I have recommended be put in practice in a regular and proper manner, but it will in most cases be requisite to repeat the leeching. Even in the advanced stage of the disease, and after coma has made its appearance, Dr. Abercrombie lays great stress on the benefits derived fromthe application of leeches; and I think I have myself saved some lives by the employment of leeches, even after the supervention of coma. In all violent cases I would recommend strongly to you the using relays of leeches from the first, to keep up a continual detraction of blood. In addition to this, the patient must be kept perfectly quiet, all loud sounds, and the stimulus of light avoided; the room should be kept cool and well-aired, the bed-covering light, the attendants few, and the nurse should be a person of cool temper and steady disposition. These are the principal measures to be employed in the treat- ment of acute inflammation of the brain in the adult; there are certain cases, however, in which you may add to these measures others of a different kind, particularly in cases where the disease has occurred as a consequence of the metastasis of inflammation from other parts. Suppose you have a case of rheumatism, or of some suppressed evacuation in which there is a metastasis to the ENCEPHALITIS. 229 brain. Under such circumstances, while you employ the means I have mentioned for the purpose of subduing cerebral inflammation, you will also put in practice the best measures for restoring the original disease. Here, however, you should bear in mind, that your attempts to bring back the original disease are always to be looked upon as secondary to those for the direct removal of the existing irritation of the brain. Some practitioners, in such cases, content themselves with endeavouring to restore the original affec- tion, but this is playing a dangerous game. An organ of vast importance to life is affected, and you cannot calculate how far the inflammation may proceed. You should never neglect taking proper steps at first to reduce inflammation, while at the same time you need not neglect the means calculated to bring back the former disease. If the encephalitis be caused by the suppression of bleed- ing piles, or a sudden checking of the menstrual flux, leeches to the anus or vulva are found useful along with the direct treatment. If the disease be produced by the repression of an exanthematous eruption, the same principles apply. You should never omit em- ploying the means for bringing back the original affection, but you should always recollect that they are to be secondary to the mea- sures adopted to directly relieve the cerebral excitement. With respect to the use of blisters, the same rules apply here as in other cases of disease treated of during the course. They are never to be used in the early stage of the disease, and while active inflammation is present; and, as a general rule, I believe it is better to apply them to the nape of the neck, or the inside of the legs, than directly to the head. There is only one case in which you can apply them with advantage to the head itself, and this is where there is coma with a cool skin. Here the stimulus of a blister is frequently found to be highly useful. As to the use of mercury in cases of acute cerebral inflammation, I think we have not as yet a sufficient number of facts on which to form any decided opinion. If we look to hydrocephalus, we shall find that there are many cases in which the symptoms did not yield to the ordinary measures until mercury was employed; this, however, we do not find to be so much the case in the acute inflammation of the brain in the adult.—I shall return to this sub- juct on a future occasion. I have little doubt that emetics are very dangerous in this disease, from the determination to the head which they produce. Any of you, gentlemen, who has vomited, cannot forget the violent sense of tension about the head with which the act is accompanied; and, if the brain be in a state of acute inflammation, you can readily conceive how injurious such an effect must «be. The use of emetics in this disease has been adopted in consequence of a misconception of the opinions of Dessault. He attributed extraordinary efficacy to the use of tartar emetic, in cases of inju- ries of the head. But you must be aware that Dessault did not give tartar emetic so much with the view of exciting emesis, as of producing a degree of nausea calculated to keep down injlanima- 230 STOKES’S THEORY AND PRACTICE OF MEDICINE. tory action. Moral, who was a pupil of his for five years, makes a statement to this effect, and says that so far from proving beneficial when it vomited, the tartar emetic was always attended with unfavourable results. When it acted on the skin, or by stool, he says the effects were favourable ; but when it vomited, the symp- toms of cerebral excitement were always increased. Under these circumstances, I think you should be cautious in having recourse to the use even of tartar emetic, after the manner of Dessault; for even in this way you run the risk of vomiting. On this point we have eight very instructive cases given by Lallemand. In the first two cases, where emetics were used, the head had been merely threatened. The emetics were followed by profuse vomiting, and this by symptoms of violent cerebral excitement and rapid death. The third case was that of a patient who had apoplexy: the emetic was followed by symptoms of inflammation of the brain and death. On dissection, there were marks of inflammation discovered round the clot. Now it has been observed, in several instances, that where the substance of the brain round an apoplectic clot became inflamed, that, in addition to the phenomena of apoplexy, symp- toms of a spasmodic affection of the muscular system supervened. Here we see, that after the use of an emetic these symptoms appeared, and their nature was verified by dissection. In the remaining five cases, where emetics were employed, the cerebral affection was rather increased than diminished; and, in some of them, disease of the digestive tube was superadded. Weighing these circumstances calmly, I think the use of emetics in aeute inflammation of the brain may be considered dangerous. With respect to opium I must say, that I am strongly opposed to its employment, at least in the early stage of encephalitis. I have seen many cases of hydrocephalus in children, in which opium seemed to be decidedly injurious ; and I believe that in all cases where there is congestion of the brain, its employment will be attended by bad effects. But when all the symptoms of active inflammation have passed away, and when there remains a peculiar nervous condition of the brain, characterised by symptoms of men- tal excitement and persistent watchfulness, somewhat resembling delirium tremens, here, I believe, that you may have recourse to opium with much benefit. In many cases where the antiphlogistic treatment had been properly employed at the commencement, there frequently remains a neurotic condition of the brain, accompanied by great irritation and absence of sleep ; and in such cases I have seen much good resulting from the use of opiates. When I speak of fever I shall return to this subject. In the treatment of this disease, I am anxious that you should always bear this principle in mind—that you cannot be too cautious in adopting means of coercion. Coercion has always a bad effect: it should never be resorted to, except in cases of extreme necessity; and you should never suffer the patient’s attendants to employ it. without your express permission. It is a common practice in hos- pitals, where the attendants always wish to save trouble, to put on ENCEPHALITIS. 231 the strait waistcoat as soon as the patient exhibits symptoms of delirium. What is generally the result of this treatment ? The poor sufferer becomes irritated by confinement, and uses the most violent efforts to liberate himself; his struggles increase the excite- ment of the brain, and prevent the measures you employ from taking effect. I have known many melancholy cases, illustrative of the abuse of the strait waistcoat. I shall give you one :—A female, of delicate habit, was attacked with fever and some delirium. She was supposed to labour under disease of the brain. They put a strait waistcoat on her, and tied her down to the bed, where she remained for several days in a most deplorable state. A medical man, who was called in to see her at this time, found her in the situation described, with her head shaved and blistered, and her strength sinking. It struck him that there was something peculiar in the case, and he asked her several questions with the view of testing her sanity; and, finding that she answered rationally, he immediately directed that the strait waistcoat should be taken off. She then told him that, during the whole course of her illness, she had laboured under pain of the right side. He examined her side, and found a large tumour in the situation of the liver. There was also an eschar on the back. She died shortly afterwards; and, on dissection, the liver was found to be in a state of extensive suppurative disease ; the brain perfectly healthy. It is unneces- sary for me to make any comment on this case. While, however, I deprecate coercion as a common mode of proceeding, I fully admit that cases will occur that demand it for the safety of the patient. The dreadful tendency to suicide is one of the characters of this disease, and must never be forgotten in any case. All that I wish to impress upon you is, that coercion must be used with great caution, and only so long as it is absolutely neces- sary. When we come to treat of the nervous systems in fever, I shall recur to this subject. In all cases of cerebral disease you should never omit enquiring into the state of the bladder, for there is often retention of urine. This is to be obviated by drawing off the urine with a catheter, two or three times a day. You will meet with cases of cerebral inflammation in the last stage, with profound coma, general paralysis, an imperceptible pulse, and tracheal rattle. It is a melancholy thing to be called to a case of this description, where the ordinary means furnished by medi- cine are so inadequate to the removal, or even the alleviation of' symptoms ; and yet it is a fact that, even under these circumstances,, cases have been cured by the adoption of an extraordinary measure. This consists in the employment of enormous and sudden counter- irritation, by pouring boiling water over the lower extremities,, while, at the same time, ice is applied to the head. This is certainly an extraordinary and barbarous method; but it has succeeded in rescuing the patient, as it were, from the jaws of death. One off the most singular cases of this kind is recorded by Lallemand— that of a man upwards of sixty, who, in consequence of a fall on 232 STOKES’S THEORY AND PRACTICE OF MEDICINE. the head, was attackd with encephalitis, which was mistaken for an essential fever until the tenth day. At this time he was first seen by Lallemand, who found him labouring under severe and long-continued syncope ; the right extremities flexed ; the hand firmly closed; the surface on this side insensible; the eyelids closed ; the eyes turned up, squinting, and insensible to light; complete loss of hearing and intelligence. The body was covered with a cold viscid sweat; the respiration frequent and stertorous, and the pulse absent. Lallemand proposed pouring boiling water on the ankles, and, at the same time, applying ice to the head, an advice which was consented to with great reluctance by the ether medical attendants. At the moment the boiling water was applied, there was a sudden motion of the whole body: the left arm was agitated, the eyes opened, and the pulse could be felt at the wrist. In half an hour the boiling water was applied to the thighs with still greater effect; colour returned to the face, and the pulse became fuller. From this time improvement went on. Deep suppurating wounds were produced by the boiling water which took more than six weeks to cicatrise. The patient’s recovery perfect. In Dr. Mackintosh’s work you will find this practice recom- mended. It is indeed an extreme remedy, and one which, for many reasons, practitioners would have repugnance to use; but it is well to be acquainted with such a powerful remedy, and to know that it has succeeded under the most desperate circum- stances. With respect to partial encephalitis, the principles of treatment are the same. In this form of disease you will often have ta contend with the prejudices of the patient, and sometimes of practi- tioners who do not recognise its existence. Its symptoms, you will remember, may at first appear slight or insidious, and to the super- ficial observer less referable to the head than elsewhere; yet the disease is full of danger, slight though it appear. The recent researches on this subject have shown, too, that it is commonly a comparatively acute disease. Andral gives a table, showing the periods in one hundred and five cases: in eighty-nine of them death occurred within a month. The liability, too, of secondary complication, with general congestion, arachnitis, or apoplexy, must be always borne in mind. When the symptoms of a local encephalitis are decided, I think you should always commence by bleeding from the arm, and then apply relays of leeches and cold lotions to the opposite side of the head. You will also find the application of tartar emetic ointment, so as to bring out an eruption as soon as possible, of great value in cases of this kind. Above all things, take care to relieve the symp- toms by prompt and decided measures before the stage of paralysis comes on, for when this arrives, I believe you can do very little in the way of cure. I have seen three cases in which, after the deple- tions, the symptoms were relieved by bringing the patients rapidly under the use of mercury; and I think local inflammation of the ENCEPHALITIS. 233 brain may be treated by mercury as well as localised inflammation of other parts. My late lamented friend, Dr. Leahy, communicated to me the particulars of two cases in which pain, spasms, and other symptoms of a local encephalitis were present, and in which com- plete relief was obtained as soon as mercurial action was brought on. I recollect an old lady who got pain in the right side of the head, with contraction of the finger of the left hand, and alternate flexions and contractions of the fore-arm, accompanied by slight lesion of the intellectual functions. She was leeched three or four times, blistered, and purged, without any decided relief. I then determined to try the effect of calomel, and was gratified to find that, according as her mouth became affected, the pain and contrac- tion of the fingers, as well as the motions of the fore-arm, diminished considerably, and as soon as full ptyalism was established all her symptoms disappeared. This case is particularly interesting, inas- much as it shows that the ordinary treatment by leeching, counter- irritation, and purging, failed in giving relief, so that we are justi- fied in attributing some value to the use of mercury. In the advanced stages of this disease, it seems right to employ a seton in the back of the neck; and I would advise all who have been attacked to continue the use of this remedy for a great length of time. The term ramollissement, or softening of the brain, is one which is very extensively used, and I fear often without any precise idea of its meaning. In ninety-nine cases out of a hundred this ramol- lissement will be found to depend upon local inflammation of the brain ; of this I do not entertain the slightest doubt. I think we may very safely consider it as analogous to the softening of the lungs, liver, or spleen, or from inflammation of their texture. There is a peculiar softening of the brain in old persons, which we cannot con- nect with actual inflammation, but in all cases in the child, and in almost every case in the adult, ramollissement of the brain will be found to depend on inflammation. I do not mean to infer from this that it is in our power to cure every case of softening of the brain, for when it once sets in, the great probability is that the texture of the affected part is destroyed ; but we can cure many cases by subduing the inflammation from which it derives its origin. Of course we cannot expect to accomplish this in the case of old per- sons, where the symptoms come on without any inflammatory phe- nomena, as in that peculiar softening of the brain which forms the subject of Rostan’s work, and occurs in persons beyond the age of seventy. This appears to be a species of senile gangrene. That form of ramollissement, which occurs in adults and children, is, however, very different from this, being, in the vast majority of cases, the result of inflammation. You will hardly ever dissect a case of partial encephalitis in the adult, or of hydrocephalus in the child, without finding more or less of this inflammatory softening. 234 STOKES’S THEORY AND PRACTICE OF MEDICINE.

Before we leave the subject of inflammation of the brain, I shall draw your attention to a brief analysis of some of the more promi- nent symptoms of this disease ; and here I am anxious to impress upon you, that the true mode of studying this subject is not by reading the descriptions given by this or that systematic writer, but by the careful perusal of monographs, in which the details of a great number of cases, occurring under different circumstances, are accurately reported. You would be mistaken, indeed, if you were to conclude that you had acquired a thorough knowledge of the symptoms of phrenitis or arachnitis by reading the description of Cullen, Thomas, or Mason Good. The only mode of studying the subject properly is, to take accurate notes of every case which you meet with, and to study with care those monographs in which a number of eases, attended by different symptoms, are detailed with impartiality. I would not occupy your attention further with this subject, but that there is much error prevailing with respect to inflammation of the brain and its membranes. Persons are in the habit of suppos- ing that these symptoms are always constant and well marked, but, the truth is, they are subject to very great varieties. The first symptom, to which I shall call your attention, is pain. This, you will recollect, is a prominent symptom of most visceral inflamma- tions, where the disease is situated on, or close to, the surface of the organ ; but, when it is deep seated, this symptom becomes more or less obscure. Now, in a case of arachnitis, we have a double source of pain—one depending upon the affections of the serous membrane, the other arising from the circumstance of disease being situated on the surface ; and hence it is that, in the great majority of cases of arachnitis, pain is a constant and prominent symptom. Still, if you were to conclude that pain is always present in arach- nitis, you would be wrong—for there are many cases on record in which it was either partially observed or completely absent. You will be greatly assisted in your pathological studies by attending to the different results of inflammation of analogous structures, for we find that in some of the inflammatory affections of serous mem- branes there is little or no pain. We may, for instance, have pleu- ritis, pericarditis, and even peritoneal inflammation latent, so far as pain is concerned; nay, many persons have gone so far as to say, that it is only where the muscular tissues of the belly are engaged that we have pain in peritonitis. I have seen pericarditis run SYMPTOMS OF CEREBRITIS. 235 through all its stages without any pain being complained of by the patient. Now, if this absence of pain be a matter of no unusual occurrence in some inflammatory affections of the pleura, pericar- dium, and peritoneum, there is no reason-why it may not occur in some cases of arachnitis. Still, it must be acknowledged that pain is one of the most remarkable and constant symptoms of arachnitis, and that, of all the serous membranes, the arachnoid seems to be endowed with the greatest sensibility. We might enquire, here, whether the pain of cerebral inflamma- tion be significant of any particular lesion of the brain. I believe that upon this point the state of our knowledge is very unsatisfac- tory. Pain, as a symptom of cerebral inflammation, occurs in very different cases. We may have it in connection with disease of the superior, lateral, or inferior parts of the brain ; we may have it in cases where the result of the disease is a serous, hemorrhagic, or purulent effusion. The rale, then, to be borne iti mind is this: first, that it is present in the great majority of cases of arachnitis; next, that it may accompany many different lesions; thirdly, that it may be absent; and lastly, that, with the same lesions, we may have pain in one case and absence of it in the other. The next subject for enquiry is, does the seat of pain generally point out the seat of inflammation? Andral distinctly affirms that it does not. In some cases, pain of the frontal region has been found to accompany disease of the ventricles, and pain in one side of the head, an affection of the arachnoid covering of both hemi- spheres. We see the same thing occurring in the case of other serous membranes. Thus, in the pleuritic inflammation of phthisis, pain is very seldom felt in the situation of the disease, but generally lower down ; and I have seen some cases in which pain has been complained of only in the sound side. I recollect a case of very extensive pneumonia, in which the patient complained only of some pain in the region of the kidney and small of the back. The pain which accompanies arachnitis generally sets in at an early period of the disease, and is characterised by great intensity— two circumstances in which it resembles the pain of pleuritis. In most cases, it is found that any thing that impedes or oppresses the circulation of the brain increases this pain; and hence it is that some practitioners are led to think, that, if pain of the head be relieved by pressure, it cannot be inflammatory. Now, I wish to call your attention to this point, because, in some cases where evi- dent marks of arachnitis were found after death, it was observed that during life the pain of the head was relieved by pressure. The patients have been found with a bandage tied firmly round the head, from which they experienced decided relief, and yet a post mortem examination gave unequivocal proof of the existence of arachnitis. So far, then, as these cases go, it appears that the mere fact of pain being relieved by pressure does not prove that it is unconnected with an inflammatory cause. The pain, too, of an arachnitis may be intermittent, and continue to exhibit this charac- ter even for a considerable length of time. I have seen many 236 STOKES’S THEORY AND PRACTICE OF MEDICINE. instances of this in children, where the little patient was seized with acute pain of the head at a particular time of the day, which, after a few hours’ duration, subsided, and then returned again the next day at precisely the, same hour, and continued in this way for several weeks, until at length his friends were surprised by the unexpected supervention of coma, convulsions, or blindness. I knew two cases of this kind in which the intermittent character of the pain was so prominent as to engross the practitioner’s whole attention; so that the real nature of the affection was overlooked, and bark prescribed. I have now witnessed three or four of these regular quotidian attacks of pain in children, which, after continu- ing for days and even weeks, were suddenly followed by perfect blindness—in some cases with, and in others without coma. You might here ask, whether pain is to be considered as a diag- nostic of arachnitis? I cannot say it is. We constantly meet with severe pain of the head without arachnitis, and every one knows that the headache of fever is by no means an indication of inflam- mation of the brain. In many cases of hysteria, the headache and determination of blood to the head are violent, and yet unconnected with inflammatory action. I know a young lady who is frequently attacked with most agonising headache, accompanied by violent throbbing of the carotids and great heat of the face and scalp. Yet, in this case it is plain that the pain cannot be inflammatory, for she has been subject to these attacks once or twice a week for the last six years, and yet continues otherwise in a state of good health. If her disease were to be measured by the violence of the pain and determination of blood to the head, it would be natural to expect that death would have long ago put a period to her sufferings. This is another proof of the truth of the opinion, that there is no single pathognomic symptom of disease. Bear this in mind. I might go farther, and say, that, whether we looked to symptoms or to signs, the rule was the same. The man who merely looks to a single sign or symptom will frequently err; it is only from the whole group of signs and symptoms presented by a disease that we can arrive at any accurate diagnosis. The state of the eye, in cases of arachnitis particularly, has attracted much attention. On this subject much valuable informa- tion has been obtained by the laborious investigations of Andral, of which I shall give an abstract. He states that the phenomena of the eye, in cases of cerebral inflammation, may be reduced to three classes; its motions, the various conditions of the pupil, and the state of vision. With respect to the first of these, it may be ob- served that in some cases we find the eyeball in constant motion; in others, it is quite fixed ; while in others the balance of muscular power is lost, and there is a constant tendency to strabismus of one eye or both. Of all these varieties in the state of motion, the last appears to be the most valuable, so far as the diagnosis of arachnitis is concerned. By many persons this strabismus is looked upon as a sign that effusion has taken place, and that the disease has reached its incurable stage; a position which I am inclined to doubt, from SYMPTOMS OP CEREBRITIS. 237 having seen cases recover in which this symptom was present. However, Andral looks upon strabismus as a very valuable sign, and thinks that, of all the lesions of motion of the eye, it is the most important with respect to the diagnosis of arachnitis of the ventricles. With respect to the condition of the pupil, it is stated in books that in the early stage you have a contracted, and in the advanced a dilated pupil, and that the latter condition signifies that etfusion into the brain has taken place. Now, the truth is that this statement must be received with great caution, and as admit- ting of numerous exceptions; for it has been established that the same lesions of the brain are sometimes accompanied by very differ- ent conditions of the pupil, and vice versa. Parent and Martinet, who have investigated the subject carefully, are the best authorities on this point, and I shall give a brief abstract of their experience. In cases where both pupils were dilated, they observed that in some there was effusion into one of the ventricles, in others, into both. In cases where there was no dilatation, they observed that in some there was serous or purulent effusion under the arachnoid, while in others, in which there was no effusion whatever, the pupil was dilated. Lastly, it was found that in some cases, where only one pupil was dilated, there was effusion into both sides of the brain. You might here ask, whether effusion into the substance, or on the surface of one side of the brain, is connected with a dilated condition of pupil? In reply to this, it may be stated that effusion into the substance—not of one, but of both hemispheres— has been known to be accompanied by a contracted state of the pupil to the last. You may also have one pupil contracted and the other dilated ; nay, you may have an alteration of these conditions —the right being dilated to-day, the left to-morrow. The mere circumstance, then, of dilatation or contraction of the pupil is no sign, when taken by itself, as to the seat or even the existence of effusion ; for you may have either condition with or without effu- sion, and you may have dilatation of the pupil of one eye with an effusion into both sides of the brain. As a general rule, however, it seems to be made out, that, in most cases of cerebral inflamma- tion terminating in effusion, there is often, towards the advanced period of the disease, some dilatation of pupil, and that this con- dition generally marks the occurrence of effusion. With respect to the affections of the function of vision, there are great varieties. Some patients have double vision—others see sparks of fire, or muscae volitantes. There are many other phe- nomena of the kind, causing a great variety in the symptoms ; and this variety is found to depend more on the susceptibility of the brain to irritation, rather than on the mere existence of irritation of the serous membrane investing it. The same rule applies to all cases of serous inflammation, the phenomena of inflammation varying according to the susceptibility of the organ which the inflamed membrane covers. Thus, for instance, one patient will have pericarditis with palpitations of the heart, another without them; their occurrence or non-occurrence merely showing that the 238 STOKES’S THEORY AMD PRACTICE OF MEDICINE. heart is more or less susceptible to irritation. So it is with respect to the brain, and the symptoms of deranged vision are connected with the greater or less susceptibility of the organ, which we know varies very considerably in different persons. This remark applies to all the forms, and, I believe, all the phenomena of meningitis. In acute disease of the brain and its membranes, we often have convulsions and paralysis, and in these symptoms also we find great variations: in some we have convulsions of one side, in some of both, in others we have paralysis, but scarcely any convulsions. The same remark also applies to these symptoms, as to some already mentioned—namely, that we cannot from them alone form an accu- rate estimate of the situation or amount of disease. You may have convulsions and paralysis of various kinds with the same kind of lesion, and you may have a variety of lesions with the same para- lysis and convulsions. The only thing that appears to be pretty well established is this—that, generally speaking, in cases where the right side of the brain is engaged, you have convulsions and paralysis of the left side of the body, and vice versd. Before I proceed to speak of delirium, I think it necessary to say a few words more with respect to convulsions, as I find Andral has not touched on a point to which I beg to call your attention. The occurrence of convulsions in a child, labouring under symptoms of inflammation of the brain, is always looked upon as formidable; and indeed it is natural that convulsions, to persons unacquainted with pathology, should seem to point out a great intensity of dis- ease. I have, however, been long of opinion that convulsions occurring during the existence of hydrocephalus in children, or of meningitis in adults, are not so dangerous as persons generally think. I will even go so far as to say, that the worst cases I have seen, in which a cure was effected, were those in which there were the greatest and most violent convulsions; and that, in most of the cases which appeared to go on without any benefit from medicine, there were scarcely any. I am of opinion that convulsions are often of benefit by giving relief to the brain. This statement must appear somewhat paradoxical, but I trust I shall be able to prove to you that it has some foundation in truth. Broussais has taught that there appear to be two great modes of reaction in the economy, to obviate the effects of abnormal stimulation applied to important viscera—fever and convulsions. The irritations which attack the cerebro spinal system may be relieved by convulsions ; those which attack the viscera may be relieved by fever and secretion. This doctrine, I think, might be expressed otherwise. The irritations of organs are often relieved by an increase, with or without alteration, of their secretions. But, as we have used the term secretion to express something material, we apply the proposition merely to the viscera of organic life. Now, it may also be extended to the organs of animal life. A violent expenditure of nervous power may relieve the brain or spinal cord, and delirium and convulsions prevent or modify organic changes, just as secretion from the lung or bowels may prevent ulceration. 239 SYMPTOMS OF CEREBRITIS. I have said that the brain might be relieved by convulsions. Let us, holding this assertion in view, compare the phenomena and results of apoplexy with those of epilepsy. In the first place, it is to be remarked that the earlier phenomena of both are the same— namely, an active congestion of the vessels of the head. Any one who has seen the first stage of both must admit this. But let us follow them up through their remaining stages. In the one, we have the determination to the head, followed by convulsions more or less violent and protracted, which, however, subside after some time, and the patient gels well; in the other, there is either death from the violent determination of blood and probable effusion, or, if the patient recovers, there is very often paralysis, showing that injury has been done to the substance of the brain. Now, here we perceive that the case of determination without convulsions is that in which there is either death or recovery with paralysis; there are no such bad consequences to be dreaded where the determina- tion to the head is followed by convulsive fits. In apoplexy we have congestion followed by death, or recovery with paralysis ; in epilepsy we have congestion, convulsions, and relief. It is plain that, if we admit the identity of the phenomena in the early periods of both, we must then also admit that the only cause of relief we can ascertain is convulsions. This idea of the subject will explain how it is that a man may continue for years subject to repealed attacks of cerebral congestion, and yet continue to enjoy tolerable health. It will also explain why it is unnecessary and sometimes even dangerous to bleed in epilepsy. It also shows why it is so often unaccompanied by paralysis, because the brain is relieved by the expenditure of its nervous energy on the muscular system. I think we should generally look upon the occurrence of convul- sions, in a case of cerebro-spinal irritation, in the light of an attempt at a crisis made by nature itself. What is a crisis ? An organ labouring under irritation is suddenly relieved by a new process taking place, either in itself or in some other part; and when we come to examine what these modes of relief are, we find them to consist in the occurrence of supersecretion, hemorrhage, exanthe- matous eruptions on the surface, or convulsions. There is no doubt that, when we look to the results of the sudden supervention of a copious secretion in an inflammatory affection of any secreting organ, the source of relief is manifest. If we take two cases of hepatitis or bronchitis—one attended with copious secretion, the other without any secretion at all—it will be easy to conceive how much more dangerous the latter is, and how much more difficult to manage. Now, if we consider the brain in this point of view, we find that it is not a secreting organ, in the ordinary acceptation, and that the only mode in which it can relieve itself is by the expenditure of its excess of nervous energy on the muscular sys- tem, or by the same expenditure of mental energy, as in the case of high delirium. I think we might fairly draw an analogy be- tween this mode of relief and that which, in other diseases, is the result of hemorrhage or secretion. One fact, at all events, appears 240 STOKES’S THEORY AND PRACTICE OF MEDICINE. certain, that in two most remarkable cases of different diseases— each, however, characterised by the same phenomena in the early stage, namely, active determination to the head—we find that the case which turns out favourably is that in which convulsions occur (namely, epilepsy); while in apoplexy, where these symptoms are absent, we have either death or recovery with paralysis. If this opinion be well grounded, it would militate strongly against the practice of checking the convulsions of meningitis by opiates. I feel convinced that this practice is wrong and dangerous; its effects may be as injurious as the arresting the reactions by astringents in a case of acute inflammation. There are two ways in which we can explain its bad effects. In the first place, opiates prove detrimental by checking the convulsions, which appear to be a mode of relief adopted by nature; and, next, they must do mis- chief from their well-known tendency to add to the existing cere- bral congestion. I have now seen a good many cases of meningeal inflammation in which convulsions took place, and where opiates were employed to remove them, and feel compelled to state that the opium has certainly relieved the convulsions, but the patients have afterwards fallen into a state of profound coma, from which they never recovered. I have witnessed this so often, that I should not discharge my duty properly, did I not warn you against the em- ployment of opium in arachnitis. The same rule most commonly holds good in cases of visceral inflammation, where an organ is in a state of irritation, and has its secretions suppressed. Here also opium, by arresting secretion and increasing congestion, will be productive of bad effects. I allude here particularly to the treat- ment of pneumonia by opium, as recommended by Dr. Armstrong, who lays great stress upon its use in full doses after having pre- mised a single bleeding. I have had some experience of this mode of treatment, and find that the effect of the opium is not to remove, but to convert a manifest into a latent disease. I have seen the pain, dyspnoea, and cough subside, but the fever continued, and the destructive process of the lung went on as usual. This is the result of my experience. I shall now make a few observations on the occurrence of deli- rium in disease of the brain. In one of my former lectures I alluded to the important fact, that, in the majority of cases of meningitis, where delirium was present, there was inflammation of the con- vexity of the brain. I stated also, that, when inflammation attacked the base of the brain, we might have it going through all its stages without delirium, and pointed out the importance of this in favour of the phrenological doctrines. Andral admits the occurrence of delirium in case of inflammation on the convexity of the brain, but his reasoning upon this subject appears to me to be inconclusive. He divides affections of the convexity of the brain into those which are characterised by delirium through their whole course, and those in which coma is the most remarkable feature ; and seems to think that, where coma is the most remarkable symptom, the results of the case are unfavourable to phrenology. But we shall find, on SYMPTOMS OP CEREBRITIS. examining these cases, that, in many of them, where coma was the predominant feature, there had been delirium in the commence- ment. He gives the details of thirty-nine cases accompanied by delirium all through, in thirty-six of which there was disease of the convexity of the brain, either simple or complicated with arach- nitis. As far, then, as his first set of cases go, they are in favour of the opinion that inflammation of the convexity of the brain is most commonly attended by delirium. It appears, also, that in those cases in which coma was the most remarkable symptom there was more or less delirium in the commencement; so that, whether we take the cases in which there was delirium all through, or those in which there was coma, the conclusions appear to be in favour of the doctrines of phrenology. I shall now proceed to make some remarks on the phenomena of organic life in cases of cerebral inflammation. In the first place, with respect to the‘tongue, we find that in simple arachnitis it is but slightly affected; there may be some trifling degree of foulness, or it may be quite clean and moist. You will observe the value of this, as connected with the diagnosis of irritation of the brain from disease of the digestive system. There are many cases of irritation of the digestive system putting on the semblance of hydrocephalus to such a degree as even to mislead an experienced practitioner. Now, if it be true that in simple arachnitis the tongue remains clean, it furnishes us with very material information, as, under such circumstances, our attention will be directed to the true seat of dis- ease. Andral says, that in some cases of arachnitis he has found the tongue red, or dry, or foul, but that at the same time there was disease of the digestive system. The majority of his cases, how- ever, were simple, and exhibited no marks of an affection of the tongue or digestive system. There is one more symptom on which I wish to offer a few observations, and that is the occurrence of vomiting in the hydro- cephalus of children. In all cases where there is obstinate vomit- ing, particularly in children, you should have your suspicions roused, and look carefully to the state of the head. Vomiting is a symptom which occurs in many cases of arachnitis ; in some it is slight, in others more constant, while in a third class it is harassing, incessant, and produced by swallowing the most unirritating sub- stances. The nature of the fluid rejected from the stomach is various—being sometimes bilious, sometimes mucous, sometimes only consisting of what has been recently drunk. In some of these cases you will find the symptoms of incessant vomiting, unaccom- panied by pain of the stomach, tenderness of the epigastrium, or any other sign of disease of the digestive system. I have even seen it co-existing with a good appetite. Many persons have been lost by such cases having been mistaken for disease of the digestive system, the practitioner being ignorant that vomiting was here only symptomatic of disease of the brain. No matter what the situation of the meningitis may be, it is now established that you may have vomiting as a common symptom. I recollect the case of a delicate STOKES’S THEORY AND PRACTICE OF MEDICINE. child, about seven years of age, who laboured for some time under catarrhal fever, on the subsidence of which she got an attack of vomiting, which came on at different times in the day, but without headache, delirium, or intolerance of light. This vomiting con- tinued from day to day; and, at the end of a week, the pupils became suddenly dilated, and coma set in, under which she died. There is one very remarkable circumstance connected with this subject, with which I am anxious you should be acquainted. Where this incessant vomiting is present, you will have the other symp- toms of meningitis more or less latent. This illustrates a law before alluded to, that, where the phenomena which are the result of sympathy with an affected organ are very prominent, those which characterise the disease of the organ itself are more or less latent. If we take the reverse of the former case, and consider a case of gastric disease, we know that the irritation of the stomach will pro- duce violent cerebral symptoms, and that here also the same law is exemplified—for we shall have absence of pain, tenderness, and vomiting. The great value of this rule is, that a knowledge of it will put you on your guard, and that the mere absence of the pecu- liar symptoms of an affection of an organ possessing extensive sym- pathies, should not lead you to conclude that there was no disease of that organ. In some remarkable cases of gastritis, the principal symptoms observed were convulsions and delirium; there was no vomiting or thirst, very little pain on pressure, and nothing remark- able in the condition of the tongue. The same latency of inflam- matory disease is frequently seen in cases of delirium tremens. With respect to respiration and the state of the pulse in menin- gitis, there is very little to be said. You may have meningeal inflammation with every variety of pulse—strong, weak, full, rapid, slow, or intermittent. Generally speaking, the pulse is, towards the close of the disease, feeble and intermitting, but you may have the disease running through all its stages without any peculiarity in the character of the pulse. Respiration seems to be very little affected, and this would appear to favour the opinions of Sir Charles Bell. There is no doubt, at least, that the sympathy of the brain with the respiratory system is much weaker than with the digestive. I shall occupy your time but very briefly oil the treatment of the hydrocephalus of children, as it appears to me to be a disease in which, of all others, the principles of treatment are most simple. The old idea of this affection was, that it was a species of dropsy, depending on the relaxed state of the cerebral vessels, and hence the term hydrocephalus. Modern pathology has shown that the occurrence of serous effusion is a mere accidental circumstance, as it is present in one case of arachnitis and absent in another. When it does occur, however, it is the result of inflammatory disease, and it is to the prevention and cure of this that the practitioner must direct his attention. With the symptoms of this disease I shall not take up your time, as you will find them sufficiently TREATMENT OF HYDROCEPHALUS. SYMPTOMS OF CEREBRITIS. 243 detailed in books; but, with respect to treatment, I shall say that hydrocephalus is a disease much more under the influence of treat- ment than persons generally think. It is said that, when once effusion has taken place, the case is hopeless, and nothing can be done. This remark appears to me to be unnecessary, for there is no symptom from which you can venture to assert that effusion has set in. You may, from the inflammatory state of the brain, have delirium, coma, deafness, blindness, and paralysis, without any effusion of serum; and in many cases life has been saved, even after the appearance of all these symptoms. This term effusion is one of the bugbears of medicine. Many patients are lost from the prevalence of false ideas connected with this subject; for, as soon as effusion is supposed to have set in, the efforts of the practitioner are given up. Hundreds of patients die of bronchitis and pneumonia, in whom life might be saved if the symptoms of effusion had been treated for those of inflammation; and so it is with respect to the brain. This effusion is not the dis- ease—it is not even a constant result of the disease. We have no certain means of ascertaining its existence; and we know, that, by a persistence in antiphlogistic treatment, life may be often saved, even after all the supposed symptoms have occurred. Take this with you as a rule in medicine: always to keep your eye more upon the causes than the effects of disease. The treatment of hydrocephalus in the child should always be active, and conducted on the same principles as those of general encephalitis in the adult. Shaving the head, bleeding when prac- ticable, repeated leeching, cold affusion, calomel, and purgatives— these are the great measures upon which we are to rely for success. It is satisfactory, too, to reflect, that many cases have been saved by the prompt and steady adoption of this simple mode of treatment. The use of mercury seems to be that on which you should most rely. Some of the most singular recoveries have occurred after ptyalism has been produced. Let me remind you, however, that the rules connected with this mode of treatment, which I pointed out in speaking of hepatitis, apply equally in this case. There is a terrible consequence of mercurial action in the lymphatic temper- ament, with which you should be acquainted ; I allude to a violent and destructive inflammation of the soft parts of the mouth and face, which has got the name of the mercurial cancrum oris. An oedematous inflammation of the cheeks, lips, and tongue, takes place, and, if not checked, rapidly runs on to extensive ulceration. I have seen one cheek, half of the nose, the lower eyelid, and the opposite angle of the mouth, utterly destroyed, in a case where but five grains of calomel were used. This drawing represents the disease, after a frightful perforation of the cheek. In this case the quantity used was nine grains. I have seen the disease from the use of so small a quantity as a grain and a half of calomel! These facts show that there is a state of the constitution in which a minute OF INTERNAL REMEDIES. 244 STOKES’S THEORY AND PRACTICE OP MEDICINE. dose of calomel may have terrible effects. The same, too, may arise from the external use of mercury. I recollect the case of a young woman in the Meath Hospital, whose head was rubbed with one dram only of mercurial ointment, for the purpose of destroying vermin. She was attacked, and with difficulty saved. The disease may also come on suddenly in a patient who has been for some time using mercury in considerable doses ; but this is the rarest case. You recognise this disease by the sudden supervention of great swelling of the lips and cheeks, so as to completely alter the expres- sion. The tongue is also swollen. All these parts are hot and tender to pressure. The breath is fetid, and the internal surface of the mouth excoriated, and often covered here and there with patches of lymph. At other times we have a circumscribed osde- matous swelling, occupying the centre of the cheek, which runs on to ulceration; but most commonly the ulceration of the external parts begins at the depending angle of the mouth. In a case of this kind, if you are called before ulceration has taken place, I believe you can often save your patient, and prevent destruction of the face. Treat the disease as a violent inflam- mation ; use repeated leeching, poulticing, and the warm bath. While you do this, you must keep up your patients strength by light nourishment and wine. Apply to the internal ulcerations the mel seruginis, the nitrate of silver, or the chloride of soda. I have now saved many cases by bold and repeated leeching. I remember one case of a man in which ninety leeches were used; he recovered perfectly. In the treatment of this affection, it is of the utmost consequence to attend to the position of the patient. By keeping him as much as possible upright, or by preventing him leaning constantly on one side, we do much to prevent the occurrence of the ulceration of the angle of the mouth. As far as I can see, hydrocephalus, when taken in time, is a very manageable disease; and there is only one case in which it is diffi- cult to treat, and that is where the cerebral affection is accompanied by symptoms of gastro-enteric disease. In several cases of hydro- cephalus, this complication certainly exists; and you have first symptoms of disease of the digestive tube, and then of the head. Such cases as these are involved in great difficulty, and in their treatment you run the hazard of falling into a twofold mistake. The first is your acting on the supposition that the disease of the head is only sympathetic, and that it will subside as soon as the abdominal symptoms are removed; the other is occupying your attention exclusively with the head. Now, there is one rule with respect to this, which I think will serve to guide you through many difficulties, and this is, never to neglect the head. Though you have first an affection of the digestive system, and then of the head, it is better (even though the symptoms of the latter still continue) to pay attention to the head. You can do this at the same time that you are attentive to the condition of the digestive organs. 245 SYMPTOMS OF CEREBRITIS. Another rule is, that the cases of disease in which the purgative plan does not answer are generally those in which there is primary inflammation of the digestive tube. Dr. Cheyne, in speaking of the treatment of hydrocephalus, says, that some cases are benefited by purgatives, others not; and that the latter are those in which there is disease of the intestinal canal. In such cases you will not irri- tate the bowels, or add to the existing inflammation by purgatives. Let the bowels be kept open by enemata, and direct your attention immediately to the head. Children with largely developed heads, and of a strumous diathesis, are very subject to this disease ; and I feel convinced that the present rage for the early mental educa- tion of children has a strong tendency to produce it in subjects of this description. I believe there are many cases of fatal hydro- cephalus from which the poor victims would have escaped, but for the pernicious efforts of the parents to make them literary prodigies. I have observed many cases of this kind among the children of persons who, having been originally situated in an humble sphere, and deprived of the benefits of education, accumulate wealth ; and then, feeling in their new condition the want of education, are anxious to communicate it to their offspring; and, with that view, have them educated with too much care, and from too early a period. The child is constantly kept at his books—his little mind is per- petually tasked—a degree of cerebral excitement is kept up—and, while he is delighting his gratified parents with the manifestations of a precocious intellect, his health is neglected, and the seeds of disease are insensibly sown. One of the most ordinary conse- quences of this early application of the mental powers is hydro- cephalus. These little creatures, too, have a congenital disposition to disease of the brain, for they have generally large heads. Such cases are examples of the results of an arrest of development. A relative condition of head exists similar to that which occurs dur- ing foetal life, and this is always accompanied by a remarkable susceptibility to inflammation. This peculiar development of head also produces a precocious state of intellect, which is increased by \ \V y '^’%l 'Ilk, >A V f -v V^^ays M'V %&&/ r' ■ -S\^,
