HEART LUDWIG, Printer and Stereotype, 39 Centre-street. PREFACE. The authors present this work to the profession with a hope that it may afford some aid to the medical man in the midst of his arduous and, sometimes, perplexing prac- tical duties, as well as to the neophite who has just en- tered the portals of the temple of medicine. While w j have endeavored to present the results of our personal experience respecting the causes, nature, and treatment of diseases, we have not failed to collate, con dense, and illustrate the discoveries and opinions of othei physicians touching medicine and the collateral sciences We have freely quoted from the writings of other reput- able physicians, with a view of presenting to the pro- fession all the varieties and shades of opinion in the homoeopathic school. These views have been arranged and introduced in proper order under the various topics dis- cussed; and it is proper in this place to remark that many of these opinions do not accord with our own. But as we are advocates of the largest liberty in all that pertains to medical thought and medical progress, we have deemed it expedient to furnish as complete a tab- leaux of the field of homoeopathic literature as possible. V VI PREFACE. Our object throughout has been to present to the medical profession and the friends of homoeopathy a com- prehensive and intelligible view of the principles and practice of our school, as it is now represented by our best writers and practitioners; to embody, as far as our wide range of subjects permitted, the latest opinions and theories of investigators of every school on pathology and collateral sciences connected with medicine; and to give to all inquirers after advanced scientific truth the oppor- tunity to investigate our principles, and to see them tested by facts, as illustrated in the clinical experience of a large number of reliable observers. From all accumulated ma- terials we have aimed to sift the true from the false, and to condense within as small a compass as possible, all reliable facts bearing upon the subjects discussed. Medical science is yet in its infancy. Our knowledge of the functions of the intricate organs of the human body, of the causes and nature of diseases, and of the effects of medicines, in health and disease, is still limited, although progressive. If we have added a mite to the general advancement, and have contributed something to the general sum of medical knowledge, we are content. CONTENTS OF VOLUME I.

At the same time that he wandered from place to place, generally intoxicated, seldom changing his clothes, or even going to bed, he was teaching fragments of truth which the world could not receive till the discoveries of four centuries should teach men how to use them. The great discovery of the Circulation of the Blood was the next step in the progress of discovery. Michael Servetus, (born in Arragon in 1509) was proceeding rapidly with the researches on this subject, when he was charged with heresy and arrested and imprisoned through the influence of John Calvin, the Reformer. When Servetus had com- pletely established the fact of the passage of the blood through the lungs, he happened to pass through Geneva; there Calvin procured his arrest, brought against him a charge of blasphemy and heresy; and Servetus was found guilty and burned at the stake (in 1553) with his books around him, to kindle the flames. The tract on the circulation wras saved by one of the judges ; and wras finally traced out by Dr. Sig- mond through Dr. Mead and the Landgrave of Hesse Cassel. The discovery rested for nearly three-fourths of a century. Twrenty- five years after the death of Servetus, William Harvey wras born in Kent, England. His education w'as prosecuted abroad and in England, and his researches occupied his time for many years before any publi- cation of this theory of the circulation was made. In 1615 he was ap- HISTORY OF MEDICINE. 49 pointed lecturer on Anatomy and Surgery in London. In this position his new views which were soon to revolutionize all medical philosophy, became known (about 1619); but he fortified himself by every possible proof that the subject could admit of, before he published his first work on The Circulation in 1628. The publication of his theory brought upon him the most bitter opposition; some of his contemporaries condemned his doctrines as presenting an unjustifiable innovation, others declaring that it was no new discovery, but had been well known before. Though he lost popularity at the time of the publication of his discoveries, and his practice was diminished by it, he lived to see his opinions establish- ed in the scientific world; he served as physician to James I., and after- wards to Charles I. He became President of the College of Physicians, and saw his bust placed in its hall before he died in 1658. The best edi- tion of his works is that of the College of Physicians published in 1666. At this period the powerful remedies introduced by Paracel- sus were still in the hands of quacks only: and Yan Helmont who con- tracted the common itch in 1640, could not be cured by regular medi- cine, and had to resort to the quack remedy sulphur. In this century the French Parliament interdicted the use of Anti- mony as a medicine, and the Faculty of Paris not only forbade the employment of all chemical remedies, but would not even allow them to be mentioned in theses, and examinations. In the same century, also, the discovery of the valves of the veins by Amatus Lusitanus was denied and ridiculed by the chief anatomists of the day. In 1615 Solomon de Caus, the discoverer of steam-power, was im- prisoned by Cardinal Richelieu in the Bicetre, and there he became a lunatic. Lord Worcester who visited him there, thus spoke to hi§ keepers : “ Misfortune and captivity have deprived him of reason ; you have made him mad, and when you threw him into that cell you shut up the greatest genius of the age.” At this period the universities, which possessed the sole power of authorizing physicians to practice medicine, were mere ecclesiastical establishments. They taught very little, but persecuted all who at- tempted to learn anything not found in the writings of Galen. When a few men attempted to learn something of Surgery by observation and experience, they were persecuted by the regular Galenist priests; who, having been prohibited by the Pope from the practice of surgery, themselves gave secret lessons in this branch to their barber servants ; and these last became the Barber Surgeons. At this time hot irons, hot oil, and hot pitch were applied to Avounds to stop bleeding; and Guy de Chauliac, asserting that it was better to let a limb drop off by sphacelation than to amputate it, compressed the limb with pitch plasters to compel it to mortify. Ambrose Pare saw the bad results of such practice, and invented the mode of arresting the bleeding by Vol. L—4. 50 HISTORY OF MEDICINE. tying the arteries, and curing the wound by mild dressings. But this discovery, though worth more to humanity than all the improvements made by the routine followers of Galen in a thousand years, was not permitted to be published ; and Pare was so cruelly persecuted for pretending to innovate upon Regular Medicine that he was compelled, for his own safety, to adduce garbled and incorrect extracts from the old authors to prove that his discoveries were made by them, and not by himself. The establishment of the important fact of the circulation of the blood did not, for a long period after its truth was admitted, produce all the advantages that might have been expected from it. For the phy- siologists of that day, in reasoning upon the powers by which this phenomenon, as well as others of the animal frame was accomplished, unfortunately took hold of the mechanical philosophy as their guide ; and the explanation of every function was immediately attempted ac- cording to the law of projectiles; the system was speedily pushed so far that it destroyed itself by the absurdity to which it was carried. The first English physician who introduced important improvements in medical practice wras Thomas Sydenham, born in 1624. After graduating at Cambridge he commenced practice in Westminster. De- voting his attention to the study of febrile diseases, and finding ample opportunities in an extensive practice, after six years experience he published in 1666 his great work “Methodus Curandi Febres.” To this work he afterwards added the experience of nine subsequent years ; and the whole of it displays the most careful observation of nature and the effects of remedies. In the treatment of small-pox he first introdu- ced the method of checking the eruptive fever by means of cool air and other antiphlogistic means, by which he found that the eruption and subsequent danger were diminished ; and the same practice has been since applied to other eruptive and febrile diseases. In the accurate histories he has left behind him of small-pox, measles, gout, hysteria, and some other diseases ; in his close discrimination between the dif- ferent varieties of the febrile maladies as they disclosed, in different seasons, and different years, peculiar epidemic constitutions of the atmosphere ; Sydenham surpassed all his predecessors, from Hippo- crates to his own time: and he has still maintained his rank as the first practitioner of his own country. He died in 1689. His work displays all the elements of a master mind, and will be referred to in all future time by the student who is ambitious to measure all the depths of the human intellect.—[Gooch, Diseas. Fern. &c. 1832.) Regular Medicine lays claim to all the accidental discoveries made by men who do not pretend to be making their voyages of discovery under her authority. The discoveries of Peruvian-bark, Vaccination, Io- dine, and Lemon-juice against scurvy, were made by accident. Peruvian- HISTORY OF MEDICINE. 51 bark was discovered by tlie Indians of South America, and was first brought to Spain in 1682. It remained in Spain seven years before it was tried by Alcaia an ecclesiastic in 1639. The medical profession was roused to fury by the introduction of this substance into popular practice. This remedy was not brought into the profession through the portals of the college; and the new discovery, says Bouillaud, had to be “ baptized in tribulation.” The physicians of Oliver Cromwell allowed him to die of ague rather than ad- minister the hated specific. In the same century the president of the College of Physicians committed Dr. Groenvelt to Newgate, for daring to prescribe Cantharides internally. Sydenham was followed by the great medical philosopher Boerhaave, who led the way to many important reforms both in theory and practice. He was born in Holland in 1668. After thoroughly studying the works of Hippocrates and Sydenham, he commenced making a selec- tion from all the ancient and modern authors ; and from these materials he constructed a new theory of Medicine, which was so well adapted to the existing state of science, and so ably explained and defended by its author, that it was generally adopted throughout Europe, and rendered its author a commanding authority for more than half a century. After several years devoted to teaching other branches he was appointed to the professorship of the practice of Medicine at Leyden in 1715. His lectures on this subject, on Chemistry and Botany rapidly extended his fame. Students flocked to him from all countries, until the little city of Leyden, which had so suddenly become the Medical Metropolis of the world, could scarcely furnish accom- modations for the votaries of science drawn together by the genius of Boerhaave. He died in 1737, and his fellow-citizens erected an ele- gant monument to his memory. His theory of the origin of diseases from acrimony, lentor, or other morbid changes in the fluids of the body, has long since been so far modified by later discoveries that it can scarcely be recognized in the form in which it appears in the medical writings of the present day. Hoffmann of Saxony was contemporary with Boerhaave. Appoint- ed by the first King of Prussia Professor of Medicine at Berlin, he in- troduced to the public through his lectures and his “ System of Ra- tional Medicine,” (a work which cost him the labor of twenty years,) an important modification of the humoral pathology. He has the merit of first directing the attention of physicians to the morbid affections of the nervous system, instead of framing mere mechanical or chemical theories ; he laid the foundation of the spasmodic hypothesis, by resolv- ing the origin of all diseases into a universal atony, or a universal spasm in the primary moving powers of the system. This theory still holds its place in modifying modern theories and practice. It was 52 HISTORY OF MEDICINE. this doctrine, combined with that of Stahl, from "which Cullen selected the materials of that theory which can not yet be said to be entirely superseded by any more recent system. The popularity of Monro hav- ing made Edinburgh the chief centre of attraction for medical students, Cullen was appointed to a professorship there in 1756, and became at once a leading spirit in the profession. The humoral pathology had governed medical practice ; though vague notions had been disseminat- ed by Stahl, of the controlling power over the noxious disease- causing agencies, that was ever exerted by the internal rational soul, which resided within the animal economy and directed all its operations. The genius of Cullen seized upon the two prominent ideas of Hoffmann and Stahl and blended them into one harmonious system. His most important work: “The First Lines of the Practice of Physic,” in four volumes octavo, published in 1784 revolutionized the theories and prac- tice of the profession. Though, controverted by Brown and Darwin, in his owm time, the theories of Cullen have never been entirely exploded. Medicine had thus reached a proud position among the sciences at the close of the eighteenth century. It was already established in the public mind as the most sublime, the most comprehensive, and the most useful of all the departments of human knowledge, and was cultivated with enthusiasm by a vast number of men of the highest order of mind in both hemispheres. In the medical schools of Europe and America new doctrines and new discoveries were being successively announced, such as never entered into the imagination of the wisest of ancient sages. Just at this time a new theory, which seemed to set at nought all the accumulated wisdom of ages, wTas proclaimed to the world by a phy- sician of Germany. In 1790 Samuel Hahnemann, then residing at Leipzig, was employed in translating Cullen’s Materia Medica; and was dissatisfied with the explanation given by that author of the anti-febrile powers of the Peruvian-bark. He determined to discover by experiment on him- self, wdiat were the real properties of the bark. He took it in consider- able quantities, while in perfect health, and found that it produced an ague, similar to the intermittent marsh fever. This remarkable fact was treasured up in the memory of Hahnemann, until its great value and significance could be rendered appreciable in the light elicited by further observations and discoveries. Hahnemann was a native of the little town of Meissen, on the Elbe, near Dresden, in Saxony, born April 10th, 1755. His father, who was a painter on porcelain, enjoined the son to avoid all the liberal pro- fessions. But the youth managed to evade his father’s injunctions, by secretly contriving for himself a midnight lamp; and by its aid he was able to gratify his intellectual longing for knowdedge, "while the members of the household "were asleep. His assiduity excited the admiration of HISTORY OF MEDICINE. 53 the school-master, and the aspiring boy was advised to pursue a more intellectual vocation than his father had designed for him. The father was displeased, and placed him in a position where mental improvement was more difficult. But he was at length moved by the solicitation of the teacher, to permit the latter to direct his son’s studies, which he did till young Samuel reached the age of 20 years. [Dudgeon’s In- troductory lecture.) He now began his medical studies at Leipzig, where he supported himself by translating French and German works into English. From Leipzig he went to Vienna, where he studied under the direction of Dr. Von Quarin, who treated him with the great- est kindness. He graduated at the university of Erlangen in 1779, on which occasion he defended a dissertation, “ Consjpectus Affectuwn Sjoasmodicoruml He had already served Baron von Bruckenthal, governor of Transylvania, for some years in the capacity of physician and librarian. He now commenced practice at Mansfeld, but soon re- moved to Dessau, and afterwards to Magdeburg. After some years in practice, he published his first medical work, giving an account of his practice in Transylvania. In this work he honestly confesses, that me- dical experience was unsatisfactory; and admits that most of his patients would have fared better if left without any treatment at all. He had now practiced his profession eight years; and he says he had bestowed the most “conscientious attention” on his patients. And he had only “learned the delusive nature of the ordinary methods of treatment.” He determined to relinquish the office of physician ; a3 he said “ it was painful” to him to “ grope in the dark, guided only by books in the sick-room, to prescribe according to this or that (fanciful) view of the nature of the disease, substances that owe to mere opinion their place in the “ Materia Medica.” “ I had,” says he, “ conscientious scruples about treating unknown morbid states in my suffering fellow creatures with these unknown medicines; which, being powerful sub- stances, may, if they be not exactly suitable, change life into death, or produce new affections, or chronic ailments, which are often much more difficult to remove than the original disease;” “ and how is the physician to know whether they are suitable or not, seeing that their peculiar special modes of action are not yet elucidated ?” “ To become in this way the murderer or the aggravator of the sufferings of my brethren of mankind, was to me a fearful thought—so fearful and distressing was it, that shortly after my marriage, I abandoned the practice and scarce- ly treated any one for fear of doing him harm,” and “occupied myself chiefly with chemistry and literary labors.”—(Hahnemann’s Letters on the necessity of a regeneration of Medicine. 1808.) In chemistry his talents found a wide field for successful exercise, and in the course of a few years prior to 1790 he published some valuable tests for ascertaining the purity of wine, and a treatise on 54 niSTOKY OF MEDICINE. Arsenic, which is still referred to by the ablest writers, as a work of great originality and scientific accuracy ; and Dr. Christison quotes the account of poisoning by Arsenic. Berzelius admitted the claims of Hahnemann to distinction as a chemist. In 1789 he was settled in Leipzig and published a medical report of some forms of disease Avhich he had treated with success; and here he described his method of preparing “soluble Mercury.” The next year he made the first step towards the discovery which was in future to infuse a regenerating influence into the whole science of Medicine. His first conception of the Homoeopathic law of cure, says Dr. Hen- derson, was not reached by the inductive method, nor has any other great discovery ever been made in that manner. “ Lord Bacon’s method was never tried by anybody but himself.” Bacon himself once attempt- ed to form a new theory of heat by gathering up all the facts he could find that had any bearing on the subject. He then tried to arrange them into a theory by placing them in tables ; and, grouping them ac- cording to various methods, “he cross-questioned them in every possible way, and could educe no general law from them, for nature thus inter- rogated was silent; a “ memorable instance of the absurdity of attempt- ing to fetter discovery by any artificial rules.” [Brewster's Life of Newton.)—Hahnemann’s mode of proceeding was very different. Hav ing abandoned the practice, he still reflected on the possibility of find ing some more successful mode of treating disease. Is it, said he, “ the nature of the art that it should not be possible to bring it to any greater certainty ? ” Shameful, blasphemous thought Shall it be said that the wisdom of the Eternal Spirit could not produce remedies to allay the sufferings from the diseases he allows to arise ?” He thought there must yet be some “easy, sure, trust-worthy method,” by which we might learn the effects of medicines, “ as to what they are really, surely, and positively serviceable for.” “ The alterations which medicines cause on the healthy body do not occur in vain: they must signif y something, else why should they occur ? What if these altera- tions have an important, an extremely important signification ? What if this be the only utterance whereby these substances can impart in- formation to the observer, respecting the end of their being ? ” “ How do medicines effect what they do in disease except by their power to alter the healthy body? Certainly in this way alone the effects can occur.” “It follows, then, that the medicine among whose symptoms these characteristics of the given case of disease occur in the most complete manner, must most certainly have the power of curing that disease; in like manner that a morbid state which a certain medicinal agent is capable of curing, must correspond to the symptoms these medicinal substances are capable of producing in the healthy body. In a word, HISTORY OF MEDICINE. 55 medicines must only have the power of curing diseases similar to those they produce in the healthy body, and only manifest such morbid actions as they are capable of curing in disease!” Such were the reasonings of Hahnemann in the day when, through the inspiration of a highly illuminated intellect, he had grasped the outline form of that great Law of Cure which was in future to recon- struct the healing art; but which the world could not receive until it should be demonstrated by an amount of evidence that had never before been demanded for the establishment of any doctrine in physical science. Like Newton, meditating the tremendous problem of At- traction, he knew that his clairvoyant mind had seized upon one of the commonest facts, with which all men were familiar, and had “borne him away to conclusions that common minds never would have reach- ed.” But Hahnemann felt from the first a deep conviction that his first conjecture embodied an ever-living truth, and that his self-evident reasonings must be true also. “ If all this be not true,” said he, “ how was it that those violent tertian and quotidian fevers which I completely cured, four or six weeks ago, (without knowing how the cure was effected,) by means of a few drops of tincture of bark, should present almost exactly the same array of symptoms that I observed in myself yesterday and to-day, after gradually taking, while in perfect health, four drachms of good Cinchona-bark by way of experiment.” Other men had developed intermittent fever by giving bark as a remedy for some other condition which they did not understand. Hahnemann alone possessed penetration enough to perceive that the disease caused by Cinchona was the very same disease that it was capable of curing : and that the remedy, both in causing and curing disease must be governed by some higher law than was yet known to men of science. He felt assured that the Being who created the universe must be the wisest and most benevolent of all beings; and that “there must somewhere exist a principle” through which the powers of the remedies he had created could be rendered available for the promotion of the happiness of “His best loved creatures.” (See Henderson, p. 119.', Through successive steps the one idea of curing disease upon the simple principle of Hike by like,” took possession of his mind ; but extensive and varied experience could alone demonstrate to the outer senses of men in an age of materialism, the truth of Homoeopathy ; though that truth was clearly embodied in his own mind in the aphorism “ Similia Similibus Curantur .” To attain that precise know ledge which experiment can only give, he tested the powers of useful remedies, deadly poisons, and articles hitherto believed to be inert he tried them on himself, his patients, and then on his friends ; and he foimd that they all possessed powers new and hitherto unsuspected 56 HISTORY OF XIEDICINF. His experiments often resulted in astonishing cures; but difficulties, such as the advocates of revolutionizing truths always meet, and such as no reformer ever before met, obstructed his path, and persecution, poverty, and the dark clouds of adversity gathered around him. To carry out his own principles it became necessary that he should pre- pare his own medicines; and in doing this he was compelled to set at defiance that ancient law of Germany that restricted the preparation of medicines to the apothecaries; public sentiment and tradition erected tremendous barriers in the wray of any man who dared to set at nought the wisdom of the wise, and threatened to scatter to the winds the counsels of the learned. In 1792 Hahnemann was requested by the reigning duke of Saxe Gotha to take charge of an asylum for the insane in Georgenthal, in the Thuringian forest. Among the patients treated by him at that time was the Hanoverian minister Klockenburg, who had been rendered insane by a satirical epigram of Kotzebue; the successful treatment of this case by Hahnemann created some sensation; and from his report of it, published in 1796, it appears that he, in that first case, instituted the system of treating the insane by mildness instead of coercion. He says: “I never allow any insane person to be punished by blows or painful corporeal inflictions, since there can be no punishment where there is no sense of responsibility; and, since such patient can not be improved, but must be rendered worse by such rough treatment.” It is believed that this is the first announcement of the modern doctrine which directs the moral treatment of the insane; though it Avas in that same year (1792), that the illustrious Pinel made his first experiment by unchaining the most furious maniac in the Bicetre at Paris; and, by treating him as a man and a friend, succeeded in restoring him to reason. But is was not by discovering new modes of curing any one disease, but by the initiation of a radical doctrine that was to revolutionize the treatment of all diseases that Hahnemann had aroused the attention, as well as the hostility of medical men. To maintain the ground he claimed, and establish his doctrines on the basis of accumulated experience and facts, was the Avork of many painful years. In 1795 he established himself in Konigslutter where he remained till 1799. During this time he published his “Friend to Health, a popular miscellany; his Pharmaceutic Lexicon; his Essay on a new principle for ascertaining the remedial poAvers of medicinal substances.” (Hufeland’s Journal 1796), and other Avorks on the absurdity of complex prescriptions and regimen in the treatment of febrile and periodical diseases. In 1800 the scarlet feArer prevailed extensively in Germany, and it was at this time that Hahnemann discovered the prophylactic poAver of Belladonna in averting this disease. For a long series of years he was depressed by poverty HISTORY OF MEDICINE. 57 and driven from one town of Germany to another by the persecutions of physicians and apothecaries. In 1803 he was without a fixed resi- dence; and, though he had reached the age of forty-eight years, and had been styled by Hufeland “ one of the most distinguished physicians of Germany,” he felt himself a stranger in every comer of his native land. At one time engaged in writing a new book; at another experi- menting on himself with a new remedy. Then, gathering up his family, his books and his medicines, he flies again before his enemies; and was at one time detained six weeks on the road by the turning over of his wagon, by which a limb of one of his children was fractured. In 1803 he published a work on the injurious effects of coffee, as it was then used. After practicing for brief periods at different places in the north of Germany, in 1805 he published “Esculapius in the Balance,” and “ The Medicine of Experience.” In the same year, Napoleon the First applied to the French academy to know if concen- trated steam, according to Fulton’s process, could propel a vessel? The question was answered by a burst of laughter, and the emperor -was extremely mortified for having shown his ignorance. “ The same body of philosophers rejected the proposition to light buildings by gas, as an impossibility: and a few years ago Mr. Arago was received with bursts of contemptuous laughter, when he wanted to speak of an electric tele- graph,—his learned confreres declaring the idea to be perfectly Utopian.” In 1808, Hahnemann wrote to Hufeland his celebrated “Letter on the urgent necessity for a reform in medicine,” in which he said: “I cannot resist the desire I feel to unveil to the public the convictions that now possess me. For eighteen years, I have wandered from the beaten track of medicine. It was a punishment to me to grope always in obscurity when called to wrestle with disease, and to prescribe medi- cinal agents which had at least an arbitrary place in the materia medica.” In 1810, while residing at Torgau, he wrote his “ Organon der rationellen Ileilkunde,” which was published at Dresden the same year. At the same time he established himse'lf in Leipzig: and, in order to obtain the privileges of a physician in that city, he defended his thesis, De Helleborismo Veterum, in 1812. From this time till 1821 Hahnemann was actively engaged in defending his new system of medicine, in teaching it, and in enlarging ts domains by new researches. In 1819 he published an improved edition of his Organon, which was further improved in a third edition, translated into French, English, and Italian, 1824. Homoeopathy was introduced into Italy by the surgeons of the Austrian army, when they entered Naples in 1821. But all the rising prospects of the reformer only strengthened the hostility of his enemies. The law which prohi- 58 HISTORY OF MEDICINE. bited physicians from preparing their own medicines still existed; and Hahnemann, who could neither find his medicines already prepared, nor find apothecaries, who would obey his instructions, was compelled to violate it. A formidable combination of interested persons demanded of the government the enforcement of its own absurd statute, and Hahnemann the founder, the first apostle and, martyr of homoeo- pathy, could no longer remain in the city which was in future to erect a monument to ask posterity to excuse the wrong she had inflicted on her noblest benefactor. Driven from Leipzig, Hahnemann found an asylum at Anhalt-Cothen, -where Prince Frederick offered him pro- tection. Here he was permitted to pi'actise his profession without fear of apothecaries, though his enemies circulated false statements, to prejudice the people against him. In 1828 he completed his great work on “Chronic Diseases,” in five volumes; and its publication was followed by other smaller works, since collected in two volumes, under the title of “Minor Writings,” 1829 to 1834. In the work on “ Chronic Diseases,” he announced and explained his theory of the origin of a great number of the most inveterate forms of disease. He says, that the majority of the cases known as palsies, asthmas, dyspepsias, con- sumptions, headaches, epilepsies, vertigoes, &c., are caused by the presence of a morbid matter or miasm existing in the body. When it comes to the skin, it produces, some of the obstinate cutaneous affections, known as, leprosies, milk-crusts, scald heads, ring-worms, itch, herpes, pustules, &c. The term Psora, he employed as a general designation, not of itch, but of all the constitutional hereditary affections described by other authors under the head of jpsoric or dys- C7'asic diseases. In 1831, at the age of 76, whem epidemic cholera had excited the alarm of all the nations of Europe, Hahnemann examined the symptoms of the disease, as reported by those who had seen it, and predicted the remedies that would be found most successful in its treatment. His directions -were printed and circulated; and their value and accuracy are attested by the general success of his disciples in the treatment of cholera asiatica. The first public hospital and school for the advancement of homoeo- pathy was established at Leipzig, and there the theory and practice of the new system of medicine continues to be taught. When Hahnemann saw old age advancing upon him, he had the gra- tification of knowing, that he had not lived and labored in vain; but that his doctrines had been accepted by some of the progressive minds in all the countries of Europe, and by many in other parts of the world. Approaching the age of seventy years, he said: “I have paid no regard to either ingratitude or persecutions in the course of my life, which, HISTORY OF MEDICINE. 59 although toilsome, has not been without satisfaction, on account of the grandeur of the end I had in view.” “ The grandeur of the end he had in view,” was rapidly unfolding itself, when these words were spoken; and it has continued to expand with increasing splendor as successive years have passed away. His wife, who had witnessed and shared his trials and sufferings, without understanding him or sympathizing with him in the greatest of them, lived to see his fame safely established; and then died in 1880. At this time his writings had made his discoveries and successful practice known far from the city in which he had been almost imprisoned by the narrow prejudices of the people. In 1835 Mile. Melanie d’Her- villy, of an ancient noble family of France, visited Hahnemann at Cothen; and so thoroughly did she comprehend the greatness of the man and his discoveries, that she became one of his most distinguished pupils. At a later period she was united to him by marriage; and, ob- taining from M. Guizot, then at the head of the cabinet of Louis Phi- lippe of France, the privilege for her husband of practicing his pro- fession in Paris, she induced him to remove to that city. The royal ordinance granting this permission, was dated August 31,1885, and from that time till his death, Hahnemann was engaged in practice at Paris. In 1843 he had reached the age of eighty-nine, but his intellect was still clear; his habits of constant and patient observation made it a pleasure to note the symptoms of disease; and his ever-glowing bene- volence inspired him with an ever-burning zeal in the cause of science and humanity. “ He was,” says Hering, “ a true man without falsity, candid and open as a child. When the last fatal hour had struck for the sublime old man, who had preserved his vigor almost to his last moments; then it was the heart of his consort, who had made his last years the brightest of his life, was at the point of breaking. “Why shouldst thou,” she said, “who hast alleviated so much suffering, suffer in thy last hour ? Providence should have allotted thee a painless death?” Then he raised his voice, as he had often done when he exhorted his disciples to hold fast to the great principles of homoeopathy: “Why should I have been thus distinguished? Each of us should here attend to the duties which God has imposed upon him. Although man may honor, more or less, yet no one has any merit. God owes nothing to me. I to Him owe all,” With these words he took leave of the world, his friends, and his foes.” As devoted admirers of the genius of Hahnemann we are still de-s sirous to do no injustice to any other benefactor of our race. It will not be claimed, that the last victory of science had been won when the founder of homoeopathy closed his eyes near the gardens of the Luxem- bourg. But, while wre admit that important discoveries have been made by others which prepared the way for a higher unfolding of the prin- 60 HISTOKY OF MEDICINE. ciples on which disease originates and may be removed, we must still claim the precise discovery made by Hahnemann, as that which of all others, the world most needed in the nineteenth century. Already the lightning had been drawn from the clouds, and all the properties of all the elements of the atmosphere had been examined with great accuracy. All the sciences, that sought to subdue the various king- doms of the physical wTorld had announced a succession of splendid victories; and strong impulses moving in minds of a high order to stir them up to search for the laws that ruled, and the causes and prin- ciples which operated in some higher sphere, above the mere physical. There were men enough employed in constructing the winding path- way by which the hill-tops might reached; the world needed a commanding genius, who, “seeing the towering, distant tops of thoughts, that men of common stature never saw,” could at once ascend to the point where the labors of other men were designed to end; and from that point take his “flight sublime” towards the brighter region that encircled the mountain top. It may not be necessary here to at- tempt to prove, that Hahnemann alone was capable of meeting the want of his age. In his mind, says Dr. Henderson, a conspicuous feature was one common to the German mind, which “ is impatient of ignorance where knowledge is impossible, most eager and enterprising, where the dark- ness is the thickest,” and must trust to the wings of conjecture more than the solid footing of observation for reaching the goal at which it aims. Without it the Homoeopathic Law wTould have floated through the world a ‘viewless spirit,’ and the extreme powTers of attenuated me- dicines would have never been discovered. The literary labors of Hahnemann extended over a wide field of labor, embracing more than seventy different works on chemistry and medicine, some of which were large volumes. He also translated about twenty-four works from the English, French, Italian, and Latin, on chemistry, medicine, agriculture, and general literature. His philosophical principles ; re thus given in Dr. Cl. Muller's Festival Speech, 9th April, at the Celebration of the 106th Anniversary of Hahnemann's birth, Leipzig:—Homoeo- pathy itself is “especially based on the peculiar observation of the dynamic element in the phenomena of life. Thus, far, from con- sidering the organic life in its various aspects of health, disease, even the medical art, and the effect of medicines on the organism as chemico- mechanical processes, instead of these, homoeopathy recognized therein the exclusive dominion of a peculiar power which is subject neither to the mechanical nor chemical laws, viz., the vital power; and the laws by which this operates are also her own. Thus not the mass—not the material as such, but only so far as it is vividly penetrated by this power, and thereby brought under the dominion of the laws of vitalitj HISTORY OF MEDICINE. 61 is it the object of her investigation and the scope of her efforts. Hahne- mann in his Organon (5th Edit. § 9, &c.) expressly recognizes an in- dependent vital power (autocracy) which in the healthy state of man as spiritual, rules to an unlimited extent over the living power of the material body, and keeps all its parts in a wonderfully harmonious tenor of sensation and activity, so that our indwelling rational spirit can employ itself for the higher objects of our existence, independent of this living instrument.” The material organism, considered apart from vital povTer, is capable of no perception, no activity, no self-support: it is only the immaterial that imparts to the former all its perception, and executes its vital action, whether in the healthy or diseased condition of the quickening principle. In disease, it is originally only the vital power that is mor- bidly out of tune, and expresses its suffering (the internal change) by abnormal states of the sensations and activities of the organism. The suffering of this diseased vital power, and the morbid powrer, and the morbid symptoms thereby originated, are an inseparable totality—one and the same thing. It is only through the psychical influence of the morbific evils that our psychical vital power can become diseased; and thus also it is only by the psychical “ dynamic” operation of medicines that it can be restored to health. This recognition of a purely dynamic efficacy in the medicines, led Hahnemann to his theory of “ potencies,” inasmuch as it brought him to the conclusion, that, by a systematic attenuation (w'hich at first he adopted merely to avoid undesirable primary and secondary action) combined with succussion, the dynamic curative powers would be exalted, and so in a manner the effect would he more powerful and free from interference.” Hahnemann as a philosopher was an opponent, aye, the very antipode of the modern system of materialism. This system of philosophy, which is the dominant one of modern times, is “ founded on the consideration of force and matter alone ; and, by virtue of and in conformity to these, of the existing and working aggregate of the external world. It is based conclusively on the re- cognition that force and matter presented inseparably one with the other, keep at work incessantly according to stringent laws; and that the immense universe, with the immense riches of its incessantly changing forms, and with the full machinery of its mighty restless movement, is only a possible and positive fact, on the supposition of and n conformity to the operation of force and matter. Its leading principle is to take as a starting-point for the discovery of results nothing whatever but wrhat— 1. Each one either knows assuredly by nature, or learns by observation. 2. Relatively, what the collective body of savans receives as posi- tively attested and established by observation; and 62 HISTORY OF MEDICINE. 3. Under all circumstances, what the rational, impartial, unprejudiced mind must consider as true.” (See Pere Buffier “Sur les premieres Yerites.”—See Fletcher’s Physiology of Pathology.) The whole theory of Hahnemann may be termed nothing but the corrollary of that of John Brown. For while the Brunonian doctrine of the cure of indirect debility by stimulants is unimpeachable in the main, yet it fails in particular instances from disregard of the special character of the stimulus in both causing and curing the particular disease. Here Hahnemann steps in and supplies the missing link, and it now becomes clear not only how a stimulus can cure an inflammation that it could cause, but also why it is not any stimulus, but only one of a special character that will do so. We see that this character must be very similar to that of the stimulus which in other circum- stances would produce inflammation. (Muller.) The leading minds of the medical profession, who preceded Hahne- mann, employed their highest powers in constructing general theories which should render close observation unnecessary. The grand object of pursuit has been a comprehensive theory of disease and of practice which shall “ bind together the scattered facts of medical knowledge, and converge into one point of view the laws of organic life.” It has been believed that such a theory “ wrould on many accounts contribute to the interest of society, that it would capacitate men of moderate abilities to practice the art of healing with real advantage to the public ; it wrould enable every one of literary acquirements to distinguish the genuine disciples of medicine from those of boastful effrontery and art- ful address ; and would teach mankind in some of the most important situations, the knowledge of themselves.”* This great desideratum of the medical philosophers was never realized, and the eighteenth century closed with the dawning light of the discoveries of Hahnemann, the im- portance of w7hich was not yet appreciated by himself. Other medical discoveries of that period are still spoken of now with admiration, though not then so received by the profession. Jenner who had not really discovered the preservative power of the vaccine disease against the the small-pox, but who appropriated a discovery which he had heard of in Gloucestershire thirty years before, was lampooned, and ridiculed, and contemptuously excluded from the honors and privileges of the college of physicians, merely for advocating before the public the truth of a principle w'hich had been knowi^for ages before. Ofother discoveries of the eighteenth and nineteenth centuries we shall not now undertake to give the history. The principal improvements in the science of medicine made during the nineteenth century have grown out of the researches of anatomists * Darwin’s Zoonomia. HISTORY OF MEDICINE. 63 and pathologists. Bichat, of whom Corvisart said “ no one had done so much in so short a time, and done it so well,” announced his dis- coveries and died at the beginning of the century. The old theories of humoralism and solidism have since been often exploded and again revived. As modified by Hamilton, the former was introduced into England by Abernethy. The two united formed the basis of the sys- tems of Pinel, Broussais, and later names which have receded before the improvements in microscopic pathology and chemistry. Pinel occupied the highest places of medicine ; a chair &t the faculty clinique, at the hospital, a seat at the institute, at the academy, titles, decorations, &c. &c. All drew their inspiration from him; books, pamphlets, journals, official and other courses were but reflections of the nosography, so styled, philosophical. In the sight of these philosophers the medical problem was stated in the terms: Given a ma- lady ; to determine its place in a nosographic category. {Id Art Med.) “ And with the calm security of a conscience at peace with itself, they ticketed, they described diseases as objects of natural history; after which, these were neatly pinned each in its case, like a butterfly or a beetle upon its cork, and the savans slept soundly. If some patient, obtuse towards the perfections of nosology insisted on being cured, they silenced the impertinent, and snored on louder than before. “ Things went on thus during fifteen years, when suddenly appeared upon the horizon “ L’Examen” of Broussais, a book which made a pro- digious stir, and created a stampede in the Pinelist Camp. “ Broussais, henceforth master of the battle-field, over-ran, ploughed and harrowed it for the reception of his new doctrines. He held forth that— “ There is no specificity in diseases,intheir causes, nor in medicines. 11 Every disease is the cry of a suffering organ; which one, we must ascertain. “ There are but two diseases, inflammation and sub-inflammation; and of these two, the second only serves pro memoriam, and as a di- verticulum. The clinical problem is reduced to this: “ Where must we place the leeches, and how many leeches must we place ? ”—(Z/Montpellier Medical, 1860.) Matters were thus beautifully simplified, and indeed the practice was simpler than this: for as gastritis constituted the immense majority of maladies, if you did but prescribe an application of leeches to the epi- gastrium, you had but one chance in a thousand against you. It was magnificent. “ All the acute diseases,—fevers, exanthems : all the chronic diseases —-dermatoses, gout, gravel, neuroses, &c.,—all these were gastrites 01 gastro-enterites, and all wrere treated by leeches and diet. Ah! the 64 HISTORY OF MEDICINE. diet, sir, was an admirable tiling. Wlnit disease could have resisted a diet, more or less absolute in its severity, prolonged during weeks, dur- ing whole months ? “It is related that a patient once sought Broussais, complaining, “ Doctor, your regimen fatigues me to the last degree ; the diet is kill- ing me ; I am literally dying of hunger.” Broussais reflected a moment, then said, “Well, you carniverous animal! I will content you.” And he allowed him a teaspoonful of broth in a glass of water.” The medical system of Broussais was only fitted to amuse the pro- fession for a few short years, when there came from St. Petersburg another giant in the person of M. Louis; a man of immense genius, if, as Buffon has affirmed, genius were only patience ; M. Louis, armed with several thousand brute facts, which he calls observations, bravely flings them at the head of the colossus of Yal the Grace, and at one blow fells it to the ground. Broussais, after making a few imperfect experiments in homoeopathy on others, tried it on himself with partial benefit; but his friends objected, and he went back to his leeches and died. The system constructed upon the bloody ruins of the temple of Broussais consists in the employment of the senses rather than of the in- tellect. To observe is simply to take account of all that strikes the external senses ; to observe and count “ how many times in a hundred or a thousand cases a certain symptom has occurred; and deduce the average. As to therapeutics, the study of signs, of indications, the determination of medical constitutions—all that is suppressed; Ave may employ, ad libitum, the first remedy at hand,” no matter what may be the nature of the disease; and then it only remains to count on your fingers how many die, and how many get well under the influence of such or such a remedy. Indeed the game of goose is algebra beside such therapeutics! “ Your school,” said d’Amador, “ has devised a neAV method. You count facts and pretend to appreciate their value by their number; you add, divide, subtract; and with candid simplicity believe that you are perfecting the methods of art.” Thus the operation of the senses and statistics comprize the whole of medicine for M. Louis. Accordingly M. Bouilland bleeds his pa- tients, while M. Delarocque evacuates them excessively upAvards and doAvnwards, M. Piedagnel inundates them with warm water. M. Stein- brenncr swells them out with cold water, M. Magendie gorges them Avith punch, M. Serre with mercury, M. Petit with bark, M. Broca with quinine, Mr. A. Barthez with alum, others Arith asses’ milk, others again Avith alcohol; Avhile some, like M. Andral, do nothing at all;—and each boasts of his successes, invoking statistics, that lady of good help, Avho 6ets every body in the right.—[JOMontpellier Medical.) The more rigid observers of nature now cultivating the Avide fields GENERAL PRINCIPLES OF MEDICAL SCIENCE. 65 of pathology have abandoned the effort to construct a true theory by counting and averaging partially observed facts. In nature, says M. Bernard, “ there never was, nor will be, such an anomaly as an average. Every thing is the absolute and certain result of fixed and definite causes. Alter these in any way, even to the least degree, and the re- sults vary accordingly, and in a fixed and certain proportion. She knows no medium, she knows nothing but a unit; and this unit is a combination of facts, varying in each, and the originating results vary- ing correspondingly—experimentation, therefore, and the accumulation of facts, can alone furnish us with the key to her enigmas—and each fact is valuable, just in proportion as all its conditions are accurately as- certained, and in that proportion only; and in collecting these facts we should be careful not to allow “ preconceived ideas” to become “ fixed ideas.” The former are necessary, indispensable: we can do nothing without them; we should only know how to abandon them when they are no longer right. The preconceived idea is always interrogative ; it addresses the question to nature, and calmly awaits the answer; ceasing to question when this is received, and adopting the fact with the same readiness, whether opposed to, or in accordance with itself.” GENERAL PRINCIPLES OF MEDICAL SCIENCE. The present position of allopathic medicine must he ascertained by- asking the opinions of its standard authors. A few of these may be permitted to speak for the profession: Prof. Christisop of the University of Edinburgh, addressing a class of graduates thus speaks of thera- peutics : “ It is of all the medical sciences the most unsettled and un- satisfactory in its present state, and the least advanced in its progress.” (Edin. Monthly Journ. Med. Sciences. Sept. 1851.) In an address delivered before the British Medical Association at Edinburgh in 1858, he said: “ Therapeutics considered as a branch, whether of medical science or medical art, and compared with the other branches of medicine, fundamentally and practically is in a backward and unsatisfactory con- dition. It is not enough to admit that for a good many years past we can neither point to a single great authority, nor to a single plausible or generally admitted theory as to the action of remedies, but even our therapeutical facts must be allowed to be too often scanty, vague, or insecurely founded.”—{Lancet, Aug. 7, 1858.) Dr. Headland of London, author of the essay on the action of me- dicines, when reviewing the relative operations of the various branches of medical science, says : “For the proper perfection of medicine as a rational science, two things are in the main needed: the first is, a right understanding of the causes and symptoms of disease;—the second, a Vou L—5. 66 GENERAL PRINCIPLES OF MEDICAL SCIENCE. correct knowledge of the action of remedies. Should our acquaintance with these two subjects he complete, we should then be able to do all that man could by any possibility effect in the alleviation of human suffer- ing. This sublime problem is already being unravelled at one end. Diagnosis and nosology are making rapid strides : and perhaps we shall soon know what we have to cure. But at the other end, our medical system is in a less satisfactory condition; and though some impatient men have essayed to cut the gordian knot, and have declared boldly on subjects of which they were entirely ignorant; yet it must be con- fessed, that in the understanding of the action of medicines and of their agency in the cure of diseases we do not so much excel our ancestors. While other sciences are moving and other inquiries are rapidly advan- cing, this subject, so momentous in its applications, has in spite of the earnest labors of a few talented investigators, made after all, but small progress.” The late Dr. Adams of Banchory, who was said to be the most learned man in the profession during the last half century, said: “ Now-a-days we have abandoned all general rules of practice, and pro- fess to be guided solely by experience. But variable and uncertain have been its results! I myself—though but verging towards the de- cline of life—can well remember the time when a physician would have run the risk of being indicted for culpable homicide if he had ventured to bleed a patient in common fever; about twenty-five years ago, vene- section in fever and in almost every disease was the established order of the day; and now, what shall I state is general practice that has been sanctioned by the experience of the present generation ? I can scarcely say;—so variable has the practice in fever and in many other diseases become of late years.” There is a widely-spreading skepticism in all the old systems of medicine. Such questions as the following are continually rising: “Is there such a thing as therapeutic science? Is the world considered as one complex individual, advancing more and more towards maturity in medical knowledge?” Some really believe that the controversies and sects are incapable of settlement: and that whilst “old divisions continue for ages, new ones arise to increase the distraction of the human mind.” To many, no doubt, the claims of homoeopathy will still continue to be classed as one of the multitude. Dr. Oesterlen (Medical Logic, Sydenham Edition, p. 238) says: “If we bring to the bedside of the same patient, a disciple of Brown or of Broussais, an empiric of the old, or one of the modern stamp, an adherent of the so-called Vienna anatomical or of the Giessen chemical school, a nerve-patholo- gist, or a blood-pathologist, each will recognize a different state of things. The opinion, which each forms of fever, and similar aggregates of symptoms, of their origin, connection and dependence upon various local or general changes and conditions, and of those in their relations DOCTRINES RESPECTING A VITAL PRINCIPLE. 67 to each other, will he different from that of the others. Each of them, if he reflects upon it at all, will form a different notion of all that he has been able to observe. He will arrange and combine the various phenomena in the patient after his own manner—that is in accordance with his own point of view. If the same remedy be administered in a given case, the assertions and opinions of each concerning its effects will equally differ; for each has expected from it different services, and modes of operation in accordance to his previously formed theory; he will, therefore, interpret what he has observed in the manner which best corresponds to his OAvn views; and in the remedy employed will acknowledge only such effects as it has been his aim to produce.” Such views as those from the work now quoted are common among the leading men of the regular profession; and one of the sharpest contro- versies they have engaged in- during the present century is now going on, to determine which is best for the patient, “Medication or Non- Medication.” Medical skepticism is openly taught from our chairs of clinical me- dicine, and from the seat whence Dr. Henderson was deposed for his revolutionary tendencies, Dr. Bennett now utters such sentiments as these: “At this time, medicine is undergoing a great revolution, and to you, gentlemen, to the rising generation, do wre look as to the agents who will accomplish it. Amidst the wreck of ancient systems, and the approaching downfall of empirical practice, you will, I trust, adhere to that plan of medical education which is based on anatomy and phy- siology. Everything promises that before long a law of true harmony will be formed out of the discordant materials which surround us; and if we your predecessors have failed, to you, I trust will belong the honor of building up a system of medicine, which from its consistency, sim- plicity, and truth, may at the same time attract the confidence of the public aud command the respect of the scientific world.” DOCTRINES RESPECTING A VITAL PRINCIPLE.—NERVOUS FLUID. DYNAMIC INFLUENCE. The universe is governed by the same divine Power that created it; and he exercises upon all animate and inanimate things a controlling influence which is perpetually in operation; but he operates in all con- ditions in accordance with certain fixed and invariable principles, usually spoken of as the Laws of Nature. All created objects are divided into two great classes, called living and dead; and they are all in some degree subject to the physical laws of nature. But living bodies are also endoived with a set of properties entirely different, called vital properties, which living matter continues to manifest so long as it is alive, and no longer. The study of life, its manifestations, is the 68 GENERAL PRINCIPLES OF MEDICAL SCIENCE. object of the science of physiology; in the state of health this vital in- fluence, perpetually emanating from the Creator, exercises an absolute sway over every portion of the body, and maintains all its functions in order and harmony, both of sensation and action; and when these con- ditions of order and harmony exist, “our indwelling rational spirit may freely employ these living healthy organs for the superior purposes of our existence.” Of this “vital principle” all authors on physiology and medicine have written something. “ There is not,” says professor Paine, “in the whole range of medical literature, one author, however devoted to the physical and chemical views of life, who does not evince the necessity of admitting a governing vita! principle, as a distinct entity, distinct from all other things in nature. I say, there cannot he produced one author of any considera- tion, who does not summon to the aid of his discussion a vital prin- ciple whenever he touches upon the abstract phenomena of life.” Thus Hippocrates speaks of the “ Phusis,” Paracelsus and Van Ilel- mont of “ Archaeus,” Stahl of “ Anima;” medical men of the present day of the “ vital principle.” “ Vis vitce, vis insitce.” But the reasonings of physiologists on this subject contain little of scientific accuracy. “ To speak of the vital forces, to give them a definition, to interpre phenomena by their aid, and yet to he ignorant of the laws which govern them, is doing nothing, or rather is doing wrorse than nothing It is to attempt an impossibility, it is to content the mind to no pur pose, to stop the search after truth. To state that the liver separates the elements of the bile from the blood by means of the vital force, is merely to assert that the bile is formed in the liver. By thus varying the expression, a dangerous illusion is established.” * In regard to the nature of the intelligence, or soul, and how it acts upon the material parts, to aid in producing the phenomena of life, we do not now propose to inquire. We are able to see its results, and appreciate its wonderful influences, but the mode of its operation we will not now attempt to explain. It pervades every part of the body, and operates in a different manner on different organs. It gives rise to sensation in the organs of sense, motion in the organs of motion, di- gestion, absorption, assimilation, respiration, circulation, &c., in the organs provided for these functions. All modifications or derangements of structure, alter the peculiar effects of this spiritual power; for it acts only through the medium of the organs as they actually exist. All deviations therefore from the normal organization of parts, induces corresponding alterations in the manifestations of the intelligence. * Matteucei on Living Beings. DOCTRINES RESPECTING A VITAL PRINCIPLE. 69 The living intelligence has no particular location, but pervades every portion of the nervous system, exercising a constant, and direct in- fluence over every organ and tissue. This is clearly apparent from the experiments of Philip, Stilling, Hall, and others, which prove, “ that the pov’er of the heart and vessels of circulation, is independent of the brain and spinal narrow,” and “ that the power of the muscles of voluntary motion, vessels of secretion, and peristaltic motion of the stomach and intestines, are independent of the nervous system, and that their relation to this system is of the same nature with that of the heart and vessels of circulation, the nervous powrer influencing them in no other way than as other stimuli and sedatives do.” From these and other experiments, Dr. Philip supposed, that the vessels possess “a principle of motion independent of their elasticity,” and identical with galvanism. The experiments of Magendie and later physiologists have shown that the hemispheres of the brain and cere- bellum may be removed in a mammiferous animal, and it will continue to experience sensation, perceiving odors, sounds, and rapid impres- sions. Vision, however, is abolished.” Dr. Dowler of New-Orleans, has instituted a series of experiments on the alligator, which exhibit in the clearest manner the peculiar operation of the living intelligence upon the organism. In one experi- ment Dr. D. divided the muscles of the neck, the cervical vertebrae, and the spinal cord, also the spinal cord between the shoulders and hips, destroyed the sympathetic nerve, and removed the intestinal viscera, “ yet, for a period of more than two hours, the alligator exhibited com- plete intelligence, volition, and voluntary motion in each and all divisions of the body. It felt, saw, defended itself / showed anger, fear, and even friendly attentions to its keeper, a black boy /” In another experiment, “ the upper portion of the skull, including a hori- zontal stratum of the brain, was removed! The animal performed a series of voluntary motions, intelligibly directed, to ward off injuries. The entire brain and the medulla oblongata were now removed, without diminishing its power to direct its limbs to any part that was pained by the slightest touch of a pin or knife. A metallic rod was passed many times within the spinal cord, completely destroying the spinal marrow beyond the hips. It was still found that both volun- tary motion and sensation remained, though their manifestations were greatly impaired.” Dr. D. concludes from these and numerous* other experiments of a similar nature, “ that voluntary motion is neither directly communicated from, n<3r regulated by the brain, or the cerubellum; that the muscles in connection with the spinal marrow, perform voluntary motions for hours after having been severed from the brain; that these motions are not only entirely independent of the brain, but may take place, though 70 GENERAL PRINCIPLES OF MEDICAL SCIENCE. imperfectly, after the destruction of the cord itself; that the trunk, as well as the brain, thinks, feels, and wills, or displays psychological phenomena j that the sensorium is not restricted to a single point, but is diffused, though uneyually, or in a diminished degree, in the periphery of the body / and that actions which take place after de- capitation, as described above, are in absolute contrast to keflex actions, being sensational, consentaneous, voluntary, and in other respects dissimilar.” Is it any more wonderful that the soul conduces to the phenomena of digestion, assimilation and appropriation, when the natural stimuli of these organs are presented to them, that sight is appreciated when the natural stimuli of the eye, the rays of light, are applied to this organ ? Is it any more singular that this spiritual stimulus should endow each structure with power to exclude all noxious substances, and select each its natural excitant, than that the sense of hearing should only appreciate one voice in the midst of a hundred other voices and instruments, whenever the will so directs ? In order to acquire a correct idea of the functions of life, it is neces- sary, in the first instance, to contemplate the body as a perfect machine —adapted in every part by a definite and special organization, to re- ceive different impressions according to the nature of the substances or excitants presented, and the offices which they are destined to per- form. Without doubt, chemical and mechanical forces exercise an important influence in the operations of this machine. The combustion of oxygen with the carbon at the lungs, and in other parts of the system, must develop heat, expansion and motive power, and mechanical causes may operate somewhat in adding to this force, yet all of these influences are wholly inadequate to accomplish and perpetuate the more com- plicated phenomena of life. It is then essential that another important agency should be everywhere present, in order to enable the organs to respond properly to their specific stimuli. Consequently we have “ super- added to the body” an intelligence, which affords a specific stimulus to every part; acting solely through each particular structure as it exists, and modified in its operation according to the modifications or altera- tions in the organs themselves. If the structure of the eye is injur ed} an imperfect image will be formed upon the retina, the intelligence will manifest itself through this injured structure, and this sense will be altogether impaired. If the structure of other organs be altered, so that their natural stimuli cannot be brought to bear as usual, the opera- tion of the spiritual stimulus will be modified in proportion, and dis- ordered function result. This mental or spiritual stimulus acts at each particular part speci- fically, and in a measure independently of other parts, causing irrita- bility of different grades in the muscular fibres, and exercising those peculiar properties every where. The influence likewise which it NERVOUS FLUID. 71 exercises upon the body as a cause of disease has never yet been pro- perly appreciated. In the ordinary waking state, the operations of the soul are mani- fested directly through the media of all the physical structures, and these manifestations are limited in extent and variety, and subject to certain fixed laws, having reference to the structures and stimuli act- ing upon them. Thus, the power and extent of vision is determined by the physical condition of the eyes and brain, (which furnishes them with blood vessels and nerves,) and the number and intensity of the rays of light which strike the retina. Light, in this instance, is the material stimulus or rather the undulatory nerve-force, which passes through the structure of the eye in the same manner as it passes through an optical instrument, producing the reflection of images upon the retina in a manner analogous to images formed in the camera of the photographer. The soul takes immediate cognizance of these images upon the retina, in precisely the same manner that it recognizes the images in the camera obscura. It is worthy of note, that these images may be formed upon the retina, and yet the soul be entirely unconscious of them; so may an absent-minded man look into the car mera obscura, filled with reflected figures, and derive no impressions from them. Without this invisible, incomprehensible, and eternal soul, the eye would be but a mere optical instrument, perhaps taking the first rank among such instruments, but entirely on a par with them, and subject to similar laws. No -imponderable agent, like electricity magnetism, or galvanism, or what has been termed animal nervous fluid, could ever enable it to appreciate impressions, or perform a single act of intelligence. Every structure of the organism, whether situated within the cranium, chest, abdomen, or in any other part, is in a similar condition in rela- tion to the soul, and without its presence and influence, is subject only to the ordinary laws of matter. It is the office of the soul to preside over the necessities of the phy- sical man—to guard against and ward off injurious influences, and to respond to all impressions made upon the textures. So long as the normal physical condition exists, and no undue influence is exerted upon the mind, a spiritual or vital equilibrium is maintained through- out the system; but if a part be attacked by an enemy in the form of inflammation, or if an undue impression is made upon the mind, this equilibrium is disturbed,—the spiritual force is unequally distributed, and disordered action follows. We append a few examples to illustrate the influence of mental im- pressions in modifying the action of the tissues : an individual in per- fect health, and undisturbed by any external influence, finds himself in a gallery of paintings. At one point a devoted daughter is seen brav- 72 GENERAL -PRINCIPLES OF MEDICAL SCIENCE. ing the horrors of a foul dungeon, to offer from her own breast suste- nance to an aged and starving father, and tvhile we look, the lachrymal glands are excited, and unbidden tears flow freely. At an other point, an inhuman monster has seized an innocent child, and is in the act of dashing out its brains against the wTall, and while we gaze, the blood mounts to the brain, the cheeks glow with indignation, and the heart throbs violently at the bare contemplation of the outrage. Another tableau meets the view, and we see the executioners in the act of cast- ing a struggling criminal into a den of poisonous serpents, and, as we behold the reptiles coiled up for a deadly spring, with fiery eyes, and forked tongues, the blood forsakes the surface, the stomach sickens, the heart sinks, and a cold shudder steals over the whole system. An- other scene presents itself; we behold a table loaded Avith the most tempting viands and fruits, and an immediate change occurs in the sa- livary glands, the mouth fills Avith saliva, the stomach indicates its Avant, and a general perturbation of the digestive system ensues. The mere sight of an epileptic often induces a corresponding complaint in others ; the indulgence of bad habits in one member of a family like snuffling, distortion of the mouth, eyes, &c., frequently bring about the same habits in other members of the family. Violent emotions from sudden intelligence, Avhether good or bad, often induce diarrhoeas, syncope, catalepsy, apoplexy, mania, &c.; fear and apprehension are most powerful predisp>osing causes of disease, and when excessive, often act as exciting causes, particularly during the prevalence of epi- demic or contagious affections, as cholera asphyxia, small-pox, yellow and typhus fevers, &c. Protracted grief is a common cause of chronic diseases, like dyspepsia, jaundice, neuralgia, hypochondria, phthisis pulmonalis, &c. Intense and exclusive application to any subject, eventually causes disease of the brain and nervous system, and mental derangement. The hypochondriac, who suffers under the effects of morbid fancy, continues to feed his malady by pondering over his ima- ginary ailments ; the monomaniac, as he dAvells upon his delusion, fans the flame that is consuming him. If an individual in the most perfect health be told by several different persons that he looks pale, haggard, and sick, it is more than probable that the impression will exercise so poAverful an influence, that he will actually feel sick, and take to his bed ; Ave have witnessed more than one example of this kind. The case of the criminal is often quoted, who died of fright by the simple flowing of tepid water over his limb, while the attendants made suitable remarks on the effects of the loss of blood, till fatal syncope Avas produced. Professor Bennett says, a butcher was brought into the ofiice of a druggist, suffering from a terrible accident. “ The man on trying to hook up a heaAry piece of meat OArer his head, slipped, and the sharp hook penetrated his arm so, that he was himself suspended. DYNAMIC INFLUENCE. 73 On being examined, he was pale, almost pulseless, and expressed him- self as suffering acute agony. The arm could not be moved without causing excessive pain, and in cutting off the sleeve, he frequently cried out; yet when the arm was exposed, it was found quite uninjured, the hook having only traversed the sleeve.” In disease also, the manner, bearing, and expression of the physician, often exert the most surpriz- ing effects upon the patient, either in ameliorating or aggravating his malady. Most diseases are attended with an exalted state of the nervous system, and with a highly sensitive and irritable condition of the mental faculties. In this condition, a doleful expression of counte- nance, or words of doubt, discouragement and sadness, are often capable of plunging the patient into the most profound state of mental and physical depression, and thus aggravating, to a serious extent, his ma- lady ; while on the other hand, a cheerful face, a lively and agreeable manner, and words of hope and encouragement usually exercise an influence of the most favorable character, and conduce very materially in bringing about a curative action of the organism. It should never be forgotten, that courage, hope, confidence, and a cheerful state of mind, are powerful tonics, and often enable the healthy system to resist the influence of contagious, epidemic, and other noxious impressions, and the sick organism to combat successfully the destructive effects of disease; while fear, apprehension, grief, despair of recovery, sadness, and depression of spirits, by impairing the resisting powers of the eco- nomy, become both predisposing, and exciting causes of disease. Show me a physician who has attained a high reputation in the treatment of difficult, and dangerous cases of disease, and I will have confidence, that he is one who carries a cheerful face; who delights in dwelling upon the bright and pleasant things of life, rather than upon those which are gloomy and dismal; and who does not fail to infuse into his patients, and all around him, confidence, hope, and comfort. The ex- pression and bearing of such a man always act as a beacon of hope, to arouse the sinking energies of the patient, and to encourage him to strive against the depressing influence of his malady. In these and other analogous instances, it is the intelligence alone which is operated on and which diffuses its influence, not over any vital properties of the organism, but upon the respiratory, circulatory, digestive, and nervous systems. We have, then, constantly operating upon the machine first, what may be termed the material or natural stimuli, and second, the immaterial or spiritual stimuli, both of which are absolutely essential to the continued performance of the functions. In some parts of the organ- ism, these material excitants, must be constantly present, in order that the system may be kept in operation. The heart and blood vessels, and the respiratory organs must be incessantly acted upon ! y the 74 GENERAL PRINCIPLES OF MEDICAL SCIENCE. blood and atmospheric air, in order to ensure life. Other parts, like the stomach, lacteals, capillaries, Ac., may be deprived of their natural stimuli for a length of time -without causing death, but not without inducing derangement of function, or causing disease. These materia stimuli, not only exercise a highly important influence in the plieno mena of life, but it is upon them that morbific and other noxious im pressions are often made in causing disease. According to Liebig, “ the slightest action of a chemical agent upon the blood, exercises an injurious influence.” Any material deviation, then, from the natural properties of the inspired air, or the other stimulants of the organism, must constitute a source of disease. The other agency exerts a not less important influence over all parts of the body, and gives rise to its manifestations in accordance with the peculiar organization and modification of each structure. The operation of this intelligence upon the organs produces that peculiar state which enables them, when supplied with their material stimuli, to accomplish their functions. It manifests its power in the capillary system in enabling these vessels to exclude the red globules; over the lacteals, in enabling them to exclude all but the nutritious portions of food, over the organs of involuntary motion, in enabling them to respond with unformity and regularity to their material exci- tants ; over the nerves of sensation and motion, in enabling them to take cognizance of injurious foreign impressions, and to exercise voluntary motions; over the organs of the special senses, in enabling them to appreciate sight, hearing, smell, taste, and touch. This spiritual in- fluence operates only through the medium, of these organs and tissues, developing specific and harmonious manifestations, according to the peculiar use and structure of each part. Under its guidance the mole- cules are appropriated and become a part of the organism. Through the same influence the system is enabled to resist, to a certain extent, morbific and other injurious impressions. It is this stimulus which endows each tissue with its specific irritability, causing each part to recognize and respond to its own natural material excitant, and offer resistance to the application of all disturbing agencies. The soul does not leave the body, until the structures are so much injured, that the functions all cease operation. Many organs may be destroyed or rendered incapable of transmitting mental or spiritual impressions, yet the intelligence, entire and unaltered of itself, will still pervade the remaining portions of the organism. It will still mani- fest itself just so far as it finds normal organs and tissues to operate through, or manifest an influence upon. The material parts alone may be impaired or obliterated, but so long as there is life, the immaterial part must pervade the body unaltered, although its manifestations may be entirely changed. PERVERSIONS OF HEALTH.—NATURE OF DISEASE. 75 PERVERSIONS OF HEALTH.—NATURE OF DISEASE. The boundary between health and disease, though in some degree familiar to all, is not easily defined. Health in perfection is perhaps never seen in such a world as ours. It is usually described as a con- dition of the organism, in which there is “freedom from pain and un- easy sensations, and freedom from all those changes in the structure oi the body that endanger life, or impede the easy and effective exercise of the vital functions.” Departures from this happy state of life present themselves to us both in form and degree in infinite variety. Disease consists in some deviation from a state of health. It may extend no farther than to some simple derangement of function, in which no alteration of structure is discovered or suspected; or may be at- tended with appreciable change of texture, and may run a longer or shorter course, with or without modification from medical treatment. The former of these grades of disease may often be properly assigned to the care of the hygienist, who, by dietetic regulations, by correct employment, food, drinks, temperature, and pure air, may restore the invalid to a state of health. The physician must also be a practical hygienist, and able to employ auxiliary agencies with scientific pro- priety, as well as to select with certainty the necessary specific remedy On the “nature of the relations of the sciences of Therapeutics and Hygiene,” Dr. Dunham remarks: “That the province of Hygiene is, to discover whatever causes may have contributed to induce or perpetuate the diseased condition, and ii possible to remove them. “ That Hygiene alone is sufficient to restore many sick persons to health, and that it is in most cases an indispensable aid to Therapeutics. “That Therapeutics concerns herself only with the discovery and selection of an individually-specific remedy for each individual case of disease; which is done in accordance with a therapeutic law. This law may be the homoeopathic formula, or it may be some broader generalization,—but there can be but one law of this kind. “ That in so far as Hygiene is concerned, homoeopathists and allo- paths occupy common ground,—the philosophy of the science being the same for both, however modified and shaded in practical application by the different therapeutics of the two schools. “ That in Therapeutics alone, that is, in the discovery and selection of the individually-specific remedy for each individual case of disease, do we differ radically from the old school of medicine,—the allopaths having in fact no science of Therapeutics whatever, their philosophy of cure being an application of the principles of Hygiene to all dis- eased conditions.* * Homoeopathy, the science of Therapeutics. 76 GENERAL PRINCIPLES OF MEDICAL SCIENCE. THERAPEUTICS. There are but three modes of treating disease. They are distin- guished as follows: 1. The Homoeopathic, which only is salutary and efficacious. It u alone leads in a direct way to a mild, sure and durable cure, without either injuring the patient, or diminishing his strength.” 2. The Allopathic or Ileteropathic. Without regarding what is really diseased in the body, it attacks those parts which are sound, in order to draw off the malady from another quarter, and direct it to- wards the latter. 3. The Antipathic or Enantiopathic, which is merely palliative. This consists in paying attention to only a single symptom or feature of the disease,—that of which the patient complains most loudly, and prescribes a remedy which may palliate that. For pains of every de- scription, Opium, which may benumb the senses and allay the pain. For diarrhoea, the same remedy to stop the peristaltic action, or an astringent to suppress the secretions. For insomnolence, the same remedy. For long-continued constipation, purgatives. For habitual debility, Wine. Of these different modes of treating disease, the first alone is truly efficient and salutary. The reason that this is true, and that all the others are pernicious, says Hahnemann, “is founded upon the dif- ference which exists between the primary action of every medicine, and the reaction, or secondary effects, produced by the living organism (the vital power;.” # At the present time there exists no uniform or general system of therapeutics, because there is no theory of disease in which universal confidence is reposed. The medical world being divided into several distinct schools, each inculcating a different doctrine concerning patho- logy and the methods of cure, and all endeavoring to sustain their favorite systems, without much regard to accuracy respecting facts, or to logic in their inductions, it is not surprising, that the science of medicine is so often looked upon by the public with distrust and dis- respect. We behold the vitalist denouncing the doctrines of the chemist and mechanician, as inconsistent and highly dangerous in practical operation, while all agree in ridiculing that system which is alone founded on accurate observation of facts, homoeopathy. It is doubtless true, that many new and valuable ideas may be de- rived from each of these conflicting schools by the medical philosopher, whose sole object is truth. Indeed, the coincidence of opinion between the father of homoeopathy and many of the most prominent advocates of the vital theory, like Paine, Bichat, Philip, &c., in regard to physio- * Hahnemann, Organon, § 63. THERAPEUTICS. 77 logy and pathology, is remarkable. These eminent authors not only agree, respecting the “properties and laws of healthy beings,” but they concur as to the changes and modifications which take place in dis- eased states of the organism. Although they entertain totally different views concerning the practical application of remedies, it will be ob- served, that the allopath often adopts the precept “ similia similibus,” in effecting his cures. Nor are there men wanting,—men, who stand high in the ranks of allopathy,—who unhesitatingly place the pathological and therapeutical doctrines of homoeopathy, far above those of either the chemical or physical schools. Thus Paine in his “Institutes of Medicine ” observes: “ It is due to truth {fiat justitia mat ccelum), that the physiologist concedes to the homoeopath, that his hypothetical views may be directed by an enlight- ened understanding of the properties and laws of healthy beings. Upon this ground, indeed, his hopes can alone repose; and even his doctrines in pathology and therapeutics are a thousandfold better, more rational, more consistent, more conducive to health and to life, than any or all of the tenets of the chemical or physical schools.” We shall not be surprised at this concession, when the opinions of Hahnemann are contrasted with those of many allopathic authors who have written since his days. The vitalists hold, “ that all disease consists in modification of the vital properties and a consequent change of function, and is, therefore, only a variation of the natural states, that the artificial cure consists in a restoration of these properties and functions, by making upon the former certain impressions, which enable them to obey their natural tendency to a state of health; that remedial agents of positive virtues operate like the truly morbific, but less profoundly in their therapeutical doses, and that the philosophy of their cure consists in establishing, in a direct manner, certain morbid alterations in the already diseased pro- perties and actions of life, which are more conducive to the natural tendency that exists in the vital properties to return from a morbid to their natural state.” {Paine) Hahnemann, in his “ Organonf says: “It is solely the morbidly af. fected vital principle which brings forth diseases : that in disease this spontaneous and immaterial vital principle, pervading the physical or- ganism, is primarily deranged by the dynamic influence of a morbific agent, which is inimical to life. Only this principle, thus disturbed, can give to the organism its abnormal sensations and incline it to the irregular actions which we call disease.” So also of the operation of remedies, Hahnemann has it, “ that the brief operation of the artificial morbific powers which are denominated medicinal, although they are stronger than natural diseases, renders it 78 GENERAL PRINCIPLES OF MEDICAL SCIENCE. possible that they may, nevertheless, be more easily overcome by the vital energies, than the latter, which are weaker. Natural diseases, simply because of their more tedious burdensome operation, can not be overcome by the unaided vital energies, until they are more strongly aroused by the physician, through the medium of a very similar, yet more powerful morbific agent, (a homoeopathic medicine). Such an agent, upon its administration, urges, as it were, the instinctive vital energies, and is substituted for the natural morbid affection hitherto existing. The vital energies now become affected by the medicine alone, yet transiently; because the medicinal disease is of short duration.” The vitalists of both schools also suppose that natural, morbific and remedial agents, possess certain peculiar and distinct properties, which enable them to exercise an influence only on particular parts of the system through the means of particular nerves ; “passing over, in the f ulfilment of this law, various intermediate nerves of more direct anatomical connection. ’ ’— {Paine.) Although we are not advocates of the vital theory thus stated, yet it must be conceded that this principle of elective affinity is so universal, as applied to the operation of the morbific and remedial agents, that the influence wdiich any substance of either class exerts upon the or- ganism, may wTith propriety be denominated its specific effect. The miasms of plague, of intermittent, yellow, and certain other fevers; the infection of contagious diseases; the virus of hydrophobia, syphilis, gonorrhoea, &c., all produce peculiar and specific effects upon the sys- tem. Each of these substances possesses the property of selecting that tissue for which it has an affinity, and of expending its entire pri- mary action upon the particular part selected. It is owing to this specific law, that medical men have been able to classify diseases ; to predict with certainty, that the exposure to the influence of morbific agents, under certain circumstances, will give rise to abnormal action in certain parts, attended with a definite and uni- form train of symptoms. It is also in virtue of this specific law, that medicines may be admi- nistered wdiich operate with certainty upon particular tissues and or- gans and effect those primary and sympathetic modifications in dis- eases of the organism, which enable nature to bring about safe and speedy cures. One of the chief objections urged against the therapeutical doctrines of homoeopathy is the supposed “ fallacy of reasoning from the effects of remedial agents upon healthy to morbid conditions.” {Paine’s In- stitutes of Medicine.) The reason adduced for this opinion, is the fact that diseased parts become modified in their action, and far more susceptible to the operation of remedies than wdien healthy. This last THI'RAPEUTIC8. 79 statement is doubtless true, and it stands, as we shall endeavor to show, at the foundation of the homoeopathic method of administering me- dicines. Although the axiom, “ contraria contrariis opponenda,v is almost universally acknowledged as a principle of faith among the different schools of allopathia, so far as theory is concerned, yet in practice, the principle u similia similibus curanturis as we have before observed, not unfrequently adopted. In order that a clear understanding may be acquired of the manner in which medicines operate, as exhibited by the old and new schools, we shall attempt to demonstrate:— 1. That most morbific and remedial agents operate specifically and with much uniformity, both in health and in disease, as causative and curative agents. 2. That all drugs produce upon the human body primary and se- condary effects, the first of which appear speedily, and when the dose has not been excessive, are of short duration, and are then succeeded by the second, which are of opposite character and permanent. 3. That in disease, the susceptibility of the affected parts to the action of remedies is vastly greater than of the same parts when in health. 4. That medicines, when administered in crude form, and in large doses, according to the doctrines and ordinary practice of the old school, whether applied directly to the diseased organ or tissue, or to a healthy structure, remote from the diseased part, are not only incom- petent to eradicate disease in a safe and speedy manner, but generally serve to aggravate the already existing symptoms, and by superindu- cing additional medicinal disease, complicate, to a serious extent, the original natural affection. 5. That when a curable natural disease has been excited in the or- ganism, attended with a definite train of morbid symptoms, a medicine capable of causing (in large doses,) a similar series of symptoms, in health, will become speedily curative of such natural disease, if admi- nistered in the attenuated doses of homoeopathy. SPECIFIC EFFECTS OF MORBIFIC AND REMEDIAL AGENTS. All are aware that the natural poisons of certain animals, the virus of hydrophobia, syphilis, gonorrhoea, and sycosis ; the miasms of plague, and of yellow, typhus, and intermittent fevers ; the infection of con- tagious diseases, &c., when introduced into the circulation, produce specific ejfects upon the human system, and give rise to definite and easily recognized symptoms. There arc other morbific agents, like intense and protracted heat and cold, atmospheric vicissitudes, excessive physical and mental exertion, 80 GENERAL PRINCIPLES OF MEDICAL SCIENCE. violent emotions, &c., that operate in a more general, but not less spe- cific manner. Their operation, when carried so far as to become mor- bific, induces debility of the nervous system ; loss of irritability in the capillary vessels, which makes them incapable of excluding the red globules, and as a consequence, developing augmented heat, swelling, redness, and pain. The influence of almost every agent, whether morbific or medicinal, appears to possess a kind of elective affinity for some particular organ or structure of the organization.” This fact is so apparent in regard to morbific agents, that it scarcely requires notice; but there are many authors who still entertain doubts respecting the specific action of me- dicines. An attentive examination of the following facts, must, how- ever, settle that question satisfactorily in the minds of all impartial inquirers. Remedial agents operate in the same specific manner, both in health and in disease; but with the difference that in the latter condition, only a very minute quantity of the specific agents is requisite to produce a salutary impres sion, on account of the augmented suspectibility to remedial impressions which diseased parts acquire. 1. “ A medicine administered in certain doses, and during a certain period of time, can produce pathological lesions analogous to those that characterize certain diseases.” 2. “This same medicine, given to a healthy individual, on the same principles, produces the characteristic symptoms of the diseases whose pathological lesions it gives rise to.” 8. “ This medicine is a specific in these same diseases.” 4. “ Specificity is not therefore an isolated fact, but the law which should guide medical treatment.” (Des specifiques en medecine, Paris / par L. J. J. Molin). The experiments of Magendie, Blake, Pereira, Rau, Liebig, Muller, Orfila, Griesselich, Molin, Matteucci, and Philip, prove conclusively, that most morbific and remedial agents, when given in massive doses, produce their effects after having been absorbed into the blood. It has also been proved with equal certainty, that foreign substances, when absorbed into the circulation, are conveyed to those structures for which they have a special affinity, and there make a specific im- pression, which modifies the function of the part, according to the na- ture of the agent, and predisposition of the individual. The Idood serves as conducting medium merely, and if the absorbed substances do not possess the power of exercising an influence upon any tissue, they may continue to circulate through the lungs until inspired air gradually neutralizes them, or they may remain for an indefinite length of time, (as sometimes happens in cases of hydrophobic virus, and fever miasms, without affecting the system), and yet retain their activity SPECIFIC EFFECTS OF MORBIFIC AND REMEDIAL AGENTS. 81 The reason of this may be, that the tissues upon which they act, are in so perfect a state of vigor as to be able to resist the power of the noxious agent, until some cause shall enfeeble the part to be affected, and thus predispose it to receive the injurious impression. It will not be denied, that both in healthy and diseased states of the organism, Cantharides, Copaibse, Cubebs, the Turpentines, Juniper, Squills, Colchicum, Digitalis, Apis-mel. Cajeputi, and most other diuretics, produce their effects by acting directly or specifically upon the kidneys, as topical irritants; that the preparations of Mercury, Nitric-acid, Iodine, &c., exercise a direct and specific action upon the glands, mucous membranes, and skin; that Senega, Phosphorus, Ipeca- cuanha, tartarized Antimony, (whether taken into the stomach, or in- jected into the veins), and many of the resins exercise a specific action upon the lungs; that Aloes, Gamboge, Colocynth act specifically upon the stomach and rectum, while Senna, Rhubarb, Scammony, Jalap, and certain other cathartics, spend their effects upon all portions of the intestinal canal; that Ergot, Savin, Pulsatilla, Madder, Tansy, &c., operate specifically upon the uterus; that Belladonna, Opium, Stra- monium, Strychnine, Hyoscyamus, Conia, and Coffee impress specifi- cally some portion of the nervous system; and in a word, that almost every drug impresses certain tissues in preference to others, and that a knowledge of the manifestations to which these different impressions give rise, can alone enable us to combat diseases. That the above enumerated substances are actually absorbed, and exert a topical effect, is apparent from the fact, that they have often been detected in the blood, secretions, excretions, and even the solids of the body. It is asserted by Flourens, “that Opium acts specifically on the cerebral lobes; that Belladonna in a limited dose, affects the tubercula quadrigemina, and in a larger dose the cerebral lobes also; that Alco- hol, in a limited dose, acts exclusively on the cerebellum, but in a larger quantity, it affects also neighboring parts; and lastly, that Nux-voinica more particularly affects the medulla-oblongata.” He also states, “ that in birds, it is possible to observe, through the cranium, changes of color, (some alterations in the vascular condition of the parts) which these agents affect in the brain.” Pereira, in his Materia Medica, also declares, that “the ammoniacal, empyreumatic and phosphoric stimu- lants, containing Ammonia and its salts, the empyreumatic oils, Phos- phorus, Musk, and Castoreum, all agree in producing a primary and specific effect on the nervous system, the energy and activity of whose functions they exalt. On account of their specific influence over the nervous system, they are administered in various spasmodic or con- vulsive diseases, especially in hysteria, and also in epilepsy and chorea. The beneficial influence of some of the vegetable tonics, (as Cinchona), in intermittent diseases, should probably be referred to the specific VCL. 1.-6- 82 GENERAL PRINCIPLES OF MEDICAL SCIENCE. effects of these agents on the nervous system. The preparations of Arsenic, Silver, Copper, Bismuth, Zinc, &c., are usually, but I think most improperly, denominated tonics. They are agents, which in small and repeated doses, as well as in layge and poisonous doses, specifically affect the nervous system.” We are also assured by Liebig, in his work on animal chemistry that “we can by remedial agents exercise an influence on every part of an organ, by substances possessing a well-defined chemical action.” It will be observed, that we have adopted, in part, the views of Muller, in regard to the operation of morbific and remedial agents. This distinguished physiologist supposes, that the blood is only the “vehicle of introduction,” and that as it passes through the tissues of different organs, the medical particles with which it is impregnated “ act on one or more parts, which are endowed writh a peculiar susceptibility to their influence.” He also supposes, “that a change is effected in the composition of the organic matter of the parts acted on.” That medicinal substances induce modifications in the functions of the organs by topical action, is proved, as we have before observed, from the fact, that medicinal particles are often found in the ex- cretions of the affected part. The inference must follow, from a careful consideration of all the facts bearing upon the subject, that the functions of the organism are generally morbidly altered by the direct action of noxious substances. (For further proofs respecting the doctrine of absorption and topical action of drugs, see the experiments of Muller, Tiedemann, Gmelin, Magendie, Matteucci, Liebig, Rau, Flourens, Du- trochet, Blake, Hering, Mayer, Christison, Orfila, and Dumas). In regard to the mode in which these substances operate, we suppose that their primary impression is made upon the sentient extremities of the nerves, impairing their integrity, and rendering them incapable of conducting the spiritual stimulus (which is an essential condition to irritability,) to the extreme vessels. It must be borne in mind, that in all inflammations, the capillaries are the “instruments of disease,” that the primary impressions of all deleterious agents are made upon these delicate structures, and that all of our remedies must be directed with reference to the state of these vessels in curing disease, “upon these vessels, all remedial agents exert their curative effects, whether by their direct action, or through the instrumentality of the nervous power.” (Paine). The extreme terminations of the nerves are so highly impressible, that the very minutest quantity of a specific agent is capable of pro- ducing prompt and decided effects, while the same agent would prove powerless if applied to the larger nerves. Thus it is that imponderable substances and mental emotions are so often the causes of disease. Here we have one reason, also, why medicines, when administered ho- SPECIFIC EFFECTS OF MORBIFIC AND REMEDIAL AGENTS. 83 moeopathically, produce those happy modifications in the affected parts which dispose them so speedily to recovery. In connection with this, if we take into consideration the extreme sensibility which diseased parts acquire to the operation of medicinal agents, we shall be unable to doubt the propriety of administering medicines according to the homoeopathic method. Muller supposes, that when impressions are made by specific sub- stances, “changes are effected in the composition of the organic matter of the parts 'acted on.” Of this, however, there is no satisfactory evi- dence. On the contrary, we know positively, that very many cases of disease occur without giving rise to any change whatever in the organic construction of the parts affected. One of the first indications generally observable in an abnormal state of an organ or tissue, is a loss of tone, or irritability and perverted function of the capillary vessels. In the experiments performed on the blood by Philip, Alston and Gallois, it was observed, that the smaller vessels were the first to succumb to foreign influences, and then, if the potency of the agent were increased, the larger vessels would become affected. Now, when we reflect, that irritability is dependent, 1., upon a nor- mal organization of parts ; 2., a regular and uniform supply of natural material stimuli, the arterial blood, &c., and, 3., a healthy action of the mind, in order that the spiritual stimulus shall make its due im- pression, we can readily conceive, how slight a cause, moral or physical? morbific or remedial, may disturb or impair this irritability, and thus induce disease. u Every part of the organism depends for the per- formance of its proper functions on the receipt of arterial blood and of nervous influence; so alterations in the supply of either of these essen- tials may modify or even suspend the functions of a part.” (Pereira?s Materia Medica.) The nerves are simply the conductors of the intelligence, and so long as their integrity, tone or conducting power remains unimpaired, this essential condition of irritability will remain. If, however, any cause acts upon them in such a manner, as to injure or destroy this important property, the stimulus of the superintending spirit is not transmitted, and, as a consequence, disease must result from the absence of one of the important requisites of irritability or con- tractility. Injurious impressions may be made upon the extreme nerves either by deleterious matters absorbed into the blood, and brought into direct contact with them, or by certain external applications, like electricity, magnetism, heat, cold, exercise. Inflammation may be excited by the operation of either of these causes, by a primary effect upon the sentient extremities of the nerves, which induces 84 GENERAL PRINCIPLES OF MEDICAL SCIENCE. loss of tone and conducting power, and, as a consequence, loss of irritability and resisting power in the capillaries. This impression is not made, as some theorists would have it, upon an immaterial principle, but upon something material, tangible and demonstrable, viz., nerves themselves. Poisons and other noxious substances, when taken into the blood, are rapidly conveyed to all parts of the body; and when they ar- rive at the structures, upon which they have a specific action, nature makes an effort to expel them through these particular parts. If the substance be active in its effects, the impression which is made upon the minute nerves of the part, will be in a corresponding manner severe. The length of time required for foreign substances to produce their effects is extremely variable. Some articles, like several of the . salts of Potash, Juniper, the Turpentines, Asparagus, Indigo, Madder, &c., are expelled through the urinary organs in a few moments, while other substances may remain in the blood for an indefinite period of time, or until some predisposing cause shall act upon the system in such a manner as to augment its suscepti- bility and place it in a condition to be affected by the morbific agent. In some instances, the morbific agent remains harmless in the circulation for months, and even years, -when suddenly some tissue becoming enfeebled and incapable of resisting the action of the specific agent, the disease in all its violence bursts forth. In cases like these, it is quite evident, that the injurious impressions can not be made upon the vital properties of parts, for the effects must be sooner propagated and rendered apparent. Neither can we suppose with the advocates of the chemical hypothesis, that the constituents of the blood become altered and contaminated with the peculiar miasms or virus, for such blood introduced into the circu- lation of a healthy individual gives rise to nothing like the original disorder. We again repeat, that the blood is simply the vehicle which conveys the poison, and that no effects are produced until the structure for which the poison has the greatest affinity, has become ready from predisposing cause, to receive the impression of the deleterious agent, and thus is specifically affected. Why it is, that morbific and remedial agents select particular organs and tissues to exert their action upon, we do not know; but that such is the fact, all medical observers will bear witness. Nor is it more surprising, than that some of the natural fluids, like the urine, gastric juice, bile, &c., remain with impunity in some parts of the body, while if they gain admission to other parts, as the cellular substance or peritoneum, they occasion inflammation, sloughing and death. Those substances in nature, which in certain modes of application to SPECIFIC EFFECTS OF MORBIFIC AND REMEDIAL AGENTS. 85 the living organism produce immediate death, and in other degrees o their power only derange the healthful operations and produce disease are usually known under the name of poisons. Poisonous substances produce disease by three different modes:# 1. By local destruction or irritation of the living surface to whicf they are applied. 2. By producing changes in the composition of the blood. 3. By direct changes in the nervous system. I. The first class of poisons embraces all substances that produce their effects in accordance with the laws of organic chemistry: such as concentrated acids, alkalis, some salts and metallic oxides, also some kinds of acrid vegetable matter. The effects of these articles vary widely according to the quantity in which they are employed, and they become deadly poisons or beneficent remedies according to the conditions under which they are used. A small quantity of Arsenic taken into the stomach excites a severe inflammation, with vomiting and diarrhoea, by which the irritated organ endeavors to expel the offending substance. If we take the one-thousandth part of a grain, a series of phenomena of a different character will be elicited. The minute particles of the poison having been tolerated in the stomach, pass out of it with its other contents; and may be ab- sorbed with the chyle from the inner surface of the intestines and con- veyed into the general circulation without producing violent symptoms. Thus the effect of a corrosive poison is entirely changed by merely re- ducing the dose. We will hereafter see, that when the dose is reduced to a quantity sufficiently small and finely attenuated, the agent would produce no perceptible effect on a person in health ; but that the same dose, charged with the dynamic force, which is developed by the process of attenuation, is capable of exerting a curative influence in a patient affected by a disease which is similar to that which Arsenic is capable of causing. Of this dynamic force, which is developed by trituration, and succus- sion in the preparation of homoeopathic attenuations, Hahnemann says: The discovery by which this development of the medicinal powers of drugs is effected “ is of inexpressible value, and so undeniable, that those who, from a want of knowledge of the resources of nature, con- sider homoeopathic attenuations as mere mechanical divisions of the original drug, must be struck dumb when they consult experience.” II. There are other substances whose particles in their ordinary state adhere so firmly together that in their unchanged condition they mani- fest no action upon the human organism except in their chemical rela- tions. Metallic gold, silver, tin, vegetable coal, silicea, &c., are en- tirely inert, even if taken in large quantities. But these apparently * Dr. H. Goullon. 86 GENERAL PRINCIPLES OF MEDICAL SCIENCE. powerless substances are, nevertheless, charged with a latent force, and by trituration with an inert substance, as sugar of milk, become changed into active medicinal agents. And the more perfectly their surface is atomized by trituration, i. e., their atoms are liberated, “ the more their latent peculiar electricity is developed, and at the same time transmitted to another vehicle, as is done by every electric-machine.” They7 have then become potentized, dynamized, having “ their latent force ren dered active through the solution of cohesion.” In order that this con- cealed or latent power might be effectually developed, Hahnemann directed that in preparing the first triturations, two Avhole hours should be consumed. III. Substances, chiefly Vegetable, which are active in their na- tural state.—Of these the number is very large, and it is remarkable that the chemical composition of such as are feeble in their action, is almost the same as that of others which are virulent poisons. They are all active in their natural state; but, as remedies, they require to be used in small quantities, and they become highly useful in remov- ing diseases and symptoms, such as they are capable of producing. ALLOPATHY. It would be very difficult to give a correct definition of the above term. The axiom, which is adopted by a portion of the disciples of the allopathic school, and upon which their hypothetical doctrines ar founded, is “ contraria contrariis opponenda.” Although distinctions are recognized between the antipathic or palliative, the allopathic or heteropathic, and the chemical methods of practice, yet in point of fact, they may all with propriety be resolved into one and the smue school. All employ venesection, emetics, purgatives, diaphoretics, and alteratives, to reduce inflammations; opium to allay pain and suppress unnatural discharges ; bark, iron, and brandy, &c., as tonics ; blisters, setons, moxas, issues and escharotics to produce counter irritation; re- vulsives, derivatives, and indeed all of those means, which are termed allopathic. Allopathists do not, however, uniformly adhere to any of the above doctrines, but often unconsciously encroach upon homoeopathic ground, and, by practicing according to the law of “ similia similibus,” effect their speediest and safest cures. Thus Rhubarb and Calomel, when administered in large, doses during health, cause irritation or inflammation of the membranous tissue of the bowels, as is indicated by the griping pains, and discharges of watery or mucous fluids ; yet these are favorite allopathic remedies for diar- rhoea and dysentery; Copaiba, Cubebs, Turpentine, and Cantharides, when given in large doses in health, induce inflammation of the mucous membranes of the urino-genital apparatus; yet these specific medicine* ALLOPATHY. 87 are almost invariably prescribed in tbe acute and chronic affections of these parts ; Ipecacuanha, in doses of twenty to thirty grains, is the most common emetic of the old school; yet this same school are constantly in the habit of administering this drug in doses of one-twelfth or one- sixteenth of a grain, in cases of obstinate nausea and vomiting, with the most happy results; inhalations also of the particles in Ipecacuanha cause asthma, cough, dyspnoea, &c.; yet it is a common remedy in small quantities for the cure of these complaints; excessive use of alco- holic liquors or opiates, often induces delirium tremen-s; yet Opium and Brandy, which exercise the same specific effect upon the brain, are the principal allopathic resources in curing this dangerous malady ; the preparations of Mercury, when given in considerable quantities, cause ulceration and sometimes gangrene and sloughing of the mouth and throat, pains in the muscles and bones, eruptions upon the skin, and inflammation of the bowels, attended with tenesmus, and mucous and bloody stools; yet for syphilitic and other ulcerations of the throat, pains in the limbs, eruptions, and bowel affections, the use of small doses of this mineral, in some form is deemed indispensable by the al- lopath. Sir Astley Cooper, in his Lectures observes : “ Children often contract syphilis in utero, and within twenty-four hours after their en- trance into the world, have the palms of their hands, the soles of their feet, and the nates covered with copper-colored eruptions ; and the nails begin to peel off, and if care be not taken, the little patient will sink under the effects of disease. In these cases you give the mother a quantity of Mercury, the influence of which is communicated to the child, through the medium of the milk, and it becomes cured of the sy- philitic disease.”—Cooper's Manual of Surgery by Castle.) This is excellent homoeopathic treatment; the Mercury in this in- stance is attenuated in the mother’s milk to a very great extent—pro- bably to such a degree that no analysis can detect it, or any scales weigh it, and yet Sir Astley Cooper assures us, that the infinitesimal quantity of Mercury, which finds its way to the milk of the mother, is sufficient to effect a speedy cure upon the child. In this instance nature, instead of art, attenuates the drug. Tartarized Antimony exer- cises a specific effect upon the lungs, stomach, and secretory organs, causing, according to Magendie, an inflammation or engorgement of the two first named organs, whether taken into the stomach or injected into the veins; yet this is the sheet-anchor of allopathy in pneumonia, pleurisy, and in the first stages of gastric or bilious fevers. Arsenic, when taken in large doses, in health, has a specific influence upon the nervous system, heart, skin, and alimentary canal; and this is an im portant old-school remedy in neuralgia, epilepsy, chorea, angina-pec- toris, cutaneous affections, and intermittent fevers. When nitrate of silver is absorbed in health, it makes a specific impression upon the nervous 88 GENERAL PRINCIPLES OF MEDICAL SCIENCE. system the brain, &c.; allopathists employ it in epilepsy, chorea, and morbid sensibility of the gastric and intestinal nerves. Large and re- peated doses of Nux-vomica or Strychnia, taken in health, produce “ri- gidity and convulsive contractions ” of the muscles ; yet in cases of trau- matic tetanus, Strychnia has effected cures in the hands of allopathic physicians, in doses of one-fourteenth to one-twentieth of a grain.— (See Report of a case by Dr. Fell,—N.- York Med. and Surg. Re- porter, No. 8.) The specific action of Nux-vomica under all circumstances is upon the cerebro-spinal system, and thence its efficacy when properly exhibited in tetanus, epilepsy, chorea, and hysteria. Belladonna, taken in health, gives rise to inflammation of the throat and a scarlet eruption upon the skin; and yet this remedy is highly extolled and extensively used as a prophylactic against scarlatina by many leading men opposed to homoeo- pathy. An eruption resembling psora is often produced by an exces- sive use of Sulphur and Iodine ; still these are the grand remedies in cu- taneous affections of this kind. Pereira prescribed Prussic-acid to a lady who had been suffering for months from gastrodynia; in a few hours, to the astonishment of every one, she was quite wrell. “ It can hardly be imagined,” says Pereira, “ that irritation of the stomach can be rapidly removed by a substance which is itself an irritant.” The direct application of blisters to surfaces affected with rheumatic, erysi- pelatous, and other natural cutaneous inflammations, is constantly recom- mended at the present time by the followers of Hippocrates. “ Ery- sipelas and other cutaneous inflammations may be removed by the direct action of Cantharides upon the part inflamed. The remedial agent in these cases varies the mode of inflammation, and thus intro- duces a modification in which the properties of life are brought into recuperative action(Fame’s Institutes of Medicine) ; yet they affect a superlative contempt for the law of “similia similibus curantur !” It is from experience alone, that the old-school physicians have learned, that Ipecac., in doses of one-twelfth to one-sixteenth of a grain, arrests, nausea and vomiting, and imparts tone and vigor to the stomach; that Calomel, in doses of one-twentieth of a grain, is invalua- ble for the cure of inflammation of the mucous membranes of the bowels: “ in cases of inflammation of the mucous tissue of the intestines, attended with frequent watery discharges, there is nothing comparable with Calomel, in doses varying from the twentieth to the eighth of a grain once in four to twelve hours.” (Paine’s Institutes of Medicine.) That Quinia, in doses of one-sixteenth or one-twentieth of a grain is more efficient in removing remittent and intermittent fevers, and as a general tonic in diseased states of the system, than when exhibited in quantities of from one to ten grains at a dose, is admitted by the best authors. “Quinia, in the dose of five to ten grains,” says Dr. Payne? ALLOPATHY. 89 “may speedily arrest an intermittent fever by its febrifuge virtue; but this is bad practice, since, by its associate tonic virtue, it is likely to increase or to induce local congestions; thus leaving the patient im- perfectly cured, and subject to relapses: I have seen, in my own family, the most formidable grade of remittent fever, of long duration, and at- tended with the foregoing complications, ardent heat, thread-like pulse, loss of mind, &c., and where hope of recovery had been abandoned, yield to less than a grain of Quinine, divided into sixteen doses.” (Institutes of Medicine). By experience also they have learned, that Strychnia in very minute quantities, will cure tetanus ; and that the class of remedies denominated alteratives, are capable of producing powerful effects upon the organism, and that too in a manner altogether unknown and imperceptible. But how do these physicians know that the virtues of these medi- cines cease at these points? Have they ever made honest trials of them in a pure form, and in doses of one-fiftieth, one-hundredth, or a still smaller proportion of a grain, and learned from actual observation, that they have then lost their power of impressing diseased structures? We venture to affirm, never, or they would long since have deserted the standard of allopathy. This leaning towards the modern theory is not altogether confined to the few practical cases, which we have cited, but some of their most eminent writers have approached so near to the views of Hahnemann, that we are at a loss whether to rank their theoretical doctrines as ho- moeopathic or allopathic. Pereira in his Materia Medica, writes as follows: “Unguents and lotions are used in cutaneous diseases, ulcers, &c.; gargles in affections of the mouth and throat; Collyria in ophthalmic diseases, and injec- tions into the vagina and uterus in affections of the urino-genital or- gans. In all such cases, we can explain the therapeutical effect in no other way, than by assuming, that the medicine sets up a new hind of action in the part affected, and that the new action subsides when the use of the medicine is suspended or desisted from.” This explanation is the true one. The medicines in these cases, as well as in all other instances where appropriate specific remedies are used, do “ set up a new hind of action in the part affected, creating a medicinal disease, which supersedes the natural one.” The only fault we have to urge against the allopathists in the treat- ment of these and analogous cases, is, that they give much too large doses, and thus create a far more violent medicinal disease, than is necessary to bring about their cures. Notwithstanding, however, their errors in exhibiting medicines in a crude and impure form, and in un- necessarily large doses, we must give them the credit, (fiat justicia 90 GENERAL PRINCIPLES OF MEDICAL SCIENCE. mat caelum), of occasionally curing disease (although unwittingly) in a “rational and consistent manner.” “When the intestinal mucous tissue” says Dr. Paine, “is affected with that condition of disease which results in a preternatural watery secretion and consequent evacuations, which is called diarrhoea, and Rhubarb is administered in a certain dose, this substance first impresses the membrane in such a way as to determine an increase of the peristaltic movement, but it simultaneously alters the morbid state of the intestinal mucous tissue in such a way, that the natural secre- tion is arrested. Whether, therefore, the Rhubarb purge, or prove astringent or tonic, a common principle and common laws are concerned throughout; an d all the sensible results depend upon certain alterar tions, which the agent effects in the vital properties and actions of the vessels or tissues which are the seat of the morbid conditions, or in which the variousphenomenawnay take place.” {Institutes of Medicine.) The same principle directs the practitioners of the old school in the treatment of many other diseases, and yet they sneer at homoeo- pathy, and hold up their own inconsistent and uncertain doctrines as philosophical and correct! They thus constantly administer medicines after the manner of the homoeopathist, abandoning their owTn theories, they practice upon the principles of our modern heresy. Gentlemen of the old school, where is your pride, where your consistency? You have the boast of antiquity; you have received your “bundle of ideas” from Hippocrates and Galen, to whom you pay reverence and alle- giance; you disdain innovations, and despise discoveries and improve- ments ; you have withstood the changes of more than two-thousand years, and by your powerful dicta have continually discouraged all original induction, and endeavored to crush in the bud every advance- ment in medical knowledge. Where is now your former pride, that you so often practically abandon your time-sacred axiom, “ contraria con- trariis,” and adopt the new heresy, “similia similibus'P Perhaps the light of modern science and discovery breaks, against your will, through the crevices of your unjointed and heterogeneous theories, or you are startled from your propriety by the overwhelming accumula- tions of fact Avhich Hahnemann and his disciples have displayed before the world; or, possibly, the disrespect and abuse of some of the most eminent and able of your caste, has impaired all confidence in, and respect for, your own dogmas and their applications, and you are at sea in search of a system. Are we wrong! If so, we have excuse in the following from the late distinguished editor of the “British and Foreign Med. Chirur. Review,” Dr. Forbes, who asserts: “1. That in a large proportion of the cases treated by allopathic physicians, the disease is cured by nature, and not by them.” ALLOPATHY. 91 “2. That in a less, blit still not in a small proportion, the disease is cured by nature in spite of them; in other words, their interference opposing instead of assisting the cure.” “3. That, consequently, in a considerable proportion of diseases, i would fare as wrell or better with patients, in the actual condition of the medical art, as more generally practiced, if all remedies, at least all active remedies, especially drugs, wTere abandoned. We repeat our readiness to admit these inferences as just, and to abide the conse- quences of their adoption.” We have thus far made allusion to that part only of the allopathic practice, which bears some approximation to the correct method. In most of the instances enumerated, specific medicines are employed,— medicines that produce a similar state when given in health, to that which they, are to cure. Although large quantities of crude and im- pure drugs are used in these instances, and the medicinal diseases are thus rendered violent and complicated, still it must be admitted that occasional cures are accomplished. But wre come now to a more interesting and momentous part of our subject. It becomes our duty to lay before our readers the doctrines and practice of allopathy, as they actually exist; to note their many in- consistencies, and to point out some of the innumerable evils which they entail upon mankind. We have seen that in the treatment of disease, the old-school phy- sicians make an indiscriminate use of thq palliative, heteropatliic, and, in a few instances, to the homoeopathic methods of practice. A general idea prevails that all diseases consist in “local determi- nations of blood,” and that no two affections of any consequence can exist in different parts of the same organism, at once. On this account it is that new diseases are created in healthy parts for the purpose of removing the primary natural one. Physicians have been led to adopt this mode of reasoning from ob- serving that the spontaneous appearance of cutaneous eruptions, dis- charges of blood, profuse perspirations, &c., occasionally afford relief to morbidly affected internal organs. Without reflecting that these re- sults are merely symptoms of the internal disorders, and that the causes upon which these signs depend are located in the blood, they at- tempt to annihilate diseases by imitating artificially these symptoms. In regard to the first position, we affirm that their premises are un- true. There are no facts, which warrant the statement, that “ no excessive determinations of blood can exist in the same individual at the same time.” Neither is it true, that the appearance of cutaneous eruptions, spontaneous sweats, diarrhoea, and discharges of blood are invariably, or even generally, indications that the affected organ is in process of restoration, or that the system at large is recovering its lost 92 GENERAL PRINCIPLES OF MEDICAL SCIENCE. energy and vigor ; since it often occurs that the symptoms of the com- plaint are all aggravated upon the supervention of either of the above occurrences. Dr. Wilson observes, that “ there is often a remarkable tendency to the worst species of haemorrhages from the bowels, towards the termina- tion of fatal cases of phrenitis.” Dr. Eberle says, “ on the day pre- ceding the fatal termination of a case of phrenitis, which came under my own observation, an exceedingly copious discharge of dissolved blood took place from the bowels, and on the following morning the hemor- rhage occurred also from the mouth and gums.”—(Practice of Physic.) Let us suppose a case of phrenitis. We have here an inflamma- tion, or a congested state of the capillaries of the brain. To relieve this inflammation and withdraw a portion of the fluid which is con- cerned in the congestion, bloodletting, both general and local, is resorted to as a primary and indispensable means of cure. By this means the general strength is reduced, the pulse increased or diminished in fre- quency, and the temperature of the skin is altered, but the congestion still continues, and the morbid and debilitated state of the extreme vessels (in which the disorder alone resides) remains the same as before. A resort is then made to revulsives and counter-irritants, in order that new inflammations may be created in healthy structures, which shall supersede that already existing in the brain. To effect this object purgatives of the drastic kind are exhibited, and blisters applied to the head, neck, and lower extremities, in order that the intestinal canal and portions of the skin, shall be placed in a state of artificial inflam- mation. Let us understand the case clearly. We have a disease consisting solely in a loss of tone and irritability of the serous vessels of the brain, which prevents them from excluding the red blood, and of per- forming properly their functions. To obviate this condition, a quan- tity of blood is abstracted, and artificial or medicinal inflammations are caused in the intestinal canal, and upon different parts of the surface of the body. We now inquire in what manner these violent means can, by any possibility, reach the seat of the malady, and impart tone and vigor to the weakened capillaries, so as to enable them to exclude from their structure the red globules, and resume their healthy function ? All will concede that inflammation consists in loss of tone and irrita- bility in these vessels, and that no cure can take place, until this im- paired irritability is restored. In inflammation, according to Philip, Hastings, Eberle, Wilson, and Allan, the capillaries of the part are in a state of debility and passive relaxation. The immediate exciting cause of the inflammation may be either stimulant or sedative. In both instances the impression is made upon the nervous filaments of the ALLOPATHY. 93 capillaries, and if the cause acts as a stimulant, the reaction which must follow this augmented action will leave these delicate nerves in a state of debility proportionate to the amount of the previous excitement. If the primary cause is directly sedative, no reaction will occur but a similar state of relaxation will obtain as in the former instance. How then, we repeat, can venesection, catharsis, and blisters effect the necessary object? They do not certainly prevent the red blood from still entering the relaxed capillary tubes, for the whole remaining mass must continue to circulate through the brain, as well as other parts of the organism, every few minutes. By lessening the quantity of blood, we also abstract a portion of that natural stimulus of the organism, which is one of the essential condi- tions of irritability. “ Every part of the organism depends for the per- formance of its proper functions, on the receipt of arterial blood and of nervous influence ; no alterations in the supply of either of these essentials may modify or even suspend the functions of a party (Pereira,—Materia Medica.) How absurd and pernicious then, in inflammations, the very essence of which is debility and loss of tone, to detract from one of those con- ditions upon which this very tone and vigor depends! As well might you remedy the breach through which the waters of a raging torrent are madly rushing, by turning off from its course some small tributary rivulet. As well attempt to suppress the leak of a storm-tossed vessel, by diverting from its proper channel a portion of the stream on which it floats. It is not the blood which is at fault; but a portion of the organism; correct therefore the cause of the disturbance by direct and appro- priate specifics, and you may then, and not till then, effect cures, safely and philosophically. Seek not to deprive the system of that fluid, which is so essential to the organism, and on whose integrity its func- tions depend; for by so doing, the cause of the malady will remain untouched. It is very true, that when a large quantity of blood is abstracted, during inflammation, there will seem to be in some instances an appa- rent amelioration of all the symptoms, but this effect is only temporary; for as soon as the reaction comes on, the enfeebled capillaries again admit the destructive “carriers of oxygen” as before; the state of con- gestion and inflammation remains, while the system at large has lost a portion of that stimulus, which conduces so materially, not only to sustain the normal integrity of the functions in health, but to aid in the restoration of enfeebled and diseased parts. The remedies, which stand next in importance in the old-school method of treating inflammation of the brain, are revulsives and cou lter 94 GENERAL PRINCIPLES OF MEDICAL SCIENCE. irritants. It is supposed, that by exciting the intestinal exhalents, in flaming the membrane of the bowels, and portions of the skin, the cir- culation is diverted from the brain and directed especially to these parts. But by this means is the brain in reality relieved ? Is the whole mass of blood thus prevented from circulating as usual through this oigan once in three or four minutes, or the character of its red globules changed ? By exhausting the energies and resisting force of distant healthy structures, and creating sympathetic symptoms throughout the body—thus complicating the already existing disease, and impairing the entire nervous and muscular energies—are the inflamed capillaries of the brain placed in a more favorable condition to recover their im- paired tone and irritability ? Every man who has a correct idea of the laws which govern the organism in health and disease, and who is willing to banish prejudice and he guided by common-sense and true philosophy, must answer in the negative. We object to these remedies, however, not only because they are in- competent to produce salutary impressions upon inflamed parts, but because of the evils of a positive character to which they give rise. The chief remedies of the old school are the preparations of Mer- cury, Opium, Antimony, and Bark. In a vast majority of all the cases treated by the practitioners of this school, one or more of these articles is made use of. Indeed scarcely a single malady of any moment can be named, in which one of these medicines is not considered in- dispensable. Let us then examine some of their effects, in allopathic doses, upon the healthy and diseased organism. 1. Mercury.—This mineral is more uncertain in its action in all states of the system, than any other article in use. It possesses the power in different constitutions and under certain circumstances of af- fecting nearly every organ and tissue of the body; and it is not in the power of the most judicious physician to say beforehand, where, or in what manner, it will exert its force. Some of the more common deleterious effects of Mercury are: ex- cessive salivation and sloughing of the gums, mouth and throat, gastro-enteritis, mercurial erethism, dysentery, cutaneous eruptions, inflammation of the periosteum and bones, nodes, excessive de- rangement of the nervous system, paralysis, tremors, necroses of the maxillary and other bones, rheumatism and ophthalmia. When Mercury is administered, even in a moderate quantity, no human being can be at all certain that one or another of these evil consequences will not result. Indeed it is the direct object oftentimes, to produce some of them to operate as counter-irritants. Whether it is employed in large or small quantities, solid, or in the ALLOPATHY. 95 form of vapor, it is of little importance, so far as its power of affecting the system is concerned. The following, from the editor of the Med. and Surg. Journillustrates the baneful influence of the vapor when inhaled: “ In 1810 the Triumph, man-of-war, and Phipps, schooner, received on hoard several tons of quicksilver, saved from the wreck of a vessel near Cadiz. In consequence of the rotting of the hags, the Mercury escaped, and the whole of the erew became more or less affected. In the space of three weeks 200 men were salivated, two died, and all the animals, cats, dogs, sheep, fowls, a canary-hird,—nay, even the rats, mice, and cockroaches were destroyed.” The following cases, resulting from the employment of Calomel, have come under our own observation, viz., three cases of necrosis of the in- ferior maxillary bones, requiring the removal of portions of the jaw; several cases of gangrene and sloughing of the mouth and throat, which have terminated fatally; a number of cases of mercurial palsy; numerous instances of ulceration of the nose, throat, &c., skin diseases, affections of the bones, nodes, rheumatic affections, &c., &c. Professor Chapman of Philadelphia, after descanting upon the woful effects, which have been so often produced by Calomel, and referring to many disgusting cases of mercurial disease, which had come under his own observation, thus concludes : “ Who is it, that can stop the career of Mercury at will, after it has taken the reins in its own destructive and ungovernable hands! He, who, for an ordinary cause, resigns the fate of his patient to Mercury, is a vile enemy to the sick; and if he is tolerably popular, will in one successful season have paved the way for the business of life; for he has enough to do ever afterwards to stop the mercurial breach of the constitutions of his dilapidated patients. He has thrown himself in fearful proximity to death, and has now to fight him at arm’s length as long as the patient maintains a miserable existence.” And this dreadful poison is the most common,—yes, the daily remedy of allopathy, for almost every disorder, whether mild or severe, acute or chronic. This is the agent with which artificial diseases are created in healthy parts, to cure primary or natural ones! This is the substance with which unfortunate mortals are drugged, from the time they come into the world until their wretched and too ofen premature departure, with its well-known and generally-admitted evils and dangers,—from the contemplation of which the well-instructed and experienced allopath shrinks with instinctive dread,—and from its questionable value in most instances of its prescription, it may justly detain our attention. Calomel and Opium are the common remedies in traditional practice for a large number of diseases. We will see to what extent they may be used in a practice that is philosophical. By glancing at the standard works on the practice of medicine, it 96 GENERAL PRINCIPLES OF MEDICAL SCIENCE. will be observed, that there is scarcely a single malady, either acute or chronic, in which one or both of these articles is not recommended as an important, if not indispensible means of cure. The allopath is taught to believe, that Mercury excites the functions of all the organs,—acts specifically upon the liver, salivary glands, heart, lungs and nervous system,—and therefore that it may be ad- ministered almost universally. Regardless of the secondary sym pathetic affections to which it usually gives rise, he attributes all of these symptoms to the natural disorder, and if the patient succumbs before the combined attacks of the primary disease and the medicinal one, he consoles himself with the reflection that he has followed his authorities and prescribed as his predecessors have done for centuries before him. Ask him, what are his views concerning inflammation, and he answers, that it consists in a debilitated and congested state of the capillaries of the part affected. Ask him, what is the methodus me- dendi of Mercury in cure of inflammation,—how any of its effects can reach the seat of the malady, the congested capillaries, and restore to them their impaired tone and healthy functions,—and he either avows his ignorance, or offers an unsatisfactory explanation. 2. Opium.—If we except Calomel, this drug, and its preparations are more frequently used by the medical men of the old school, than any other article in the materia medica. Possessing the power, as i does in an eminent degree, when exhibited in large doses, of covering (not curing) symptoms, and of shutting the mouths of clamorous and inquiring patients, it is used constantly and indiscriminately in nearly all protracted maladies. Let us then briefly examine the effects of opium in health and dis- ease, and see if it possesses the wonderful property of reaching every structure, and of counteracting so many diverse and contradictory symptoms. Its effects upon the human system, in medium doses, are in the first instance stimulating, but in a short time this is followed by a condi- tion of diminished sensibility and desire to sleep. This state “ continues from eight to twelve hours, and is followed by nausea, headache, tremors, and other symptoms of diminished and ii'regular nervous energy. All of the secretions, with the exception of that from the skin, are either suspended or diminished.” (Wood and Bache, U. S. Dispensatory.) These effects, with a very few exceptions, are uniform under all circumstances, so far as we can judge. How, then, is this substance applicable to the treatment of so many diseases? We have remarked, that in a large proportion of all known mala- dies, there exists an inflammation of an acute or sub-acute character in ALLOPATHY. 97 some part of the organism, and it is the presence of this inflammation which maintains and perpetuates the disease. We have also observed that all inflammations consist in a congested state of the capillaries of the part affected, caused and kept up by a loss of tone, resisting power, or irritability, which disables them from resisting the intromission of red blood. It is apparent, then, that in order to prove efficient, such remedies should be exhibited as are capable of acting upon the seat of the com- plaint, and of restoring the delicate capillary nerves to their normal state of integrity. Opium cannot accomplish this, for its operation tends to impair the nervous energy, instead of adding vigor, to dry up most of the secretions, instead of aiding nature to give vent to the poisonous, and pent-up fluid; it induces nausea, headache, tremors, and many other medicinal symptoms of sufficient severity to make a healthy man sick, or to complicate to a serious extent any existing na- tural affection. If we have urged, that opiates have the power of allaying pain, while other more efficient measures are pursued to effect the cures, we reply, that by covering up the pain, the real state of the case is con- cealed; other new symptoms set in, which will be unnoticed by the benumbed patient, while secondary sympathetic affections will be pro- pagated to every part of the body, aggravating and complicating the original disorder. Opium is highly extolled in low forms of fever and other complaints, where the powers of the system are in an exhausted condition. But let it be remembered, that the stimulating effect of this drug is of short duration, and that the corresponding reaction or depression will bear an exact ratio to the previous exaltation. This law is fundamen- tal ; for the system possesses but a definite and limited amount of vital power, and is capable of resisting only a limited degree of unnatural action or disease, so that we can readily perceive how opiates and1 stimulants must ultimately prove deleterious. It is true, that perspiration is promoted by the use of this narcotic, but this does not cure. Sweating is merely a symptom, and it may be favorable or otherwise. When excited artificially by medicine it is not productive of benefit, because this adds nothing towards invigorat- ing the weakened capillaries. “Perspiration,” says Dr. Paine, “induced by medicine is of little mo- ment, unless the remedy simultaneously impresses, direct y or indi- rectly, the parts diseased/ and then the salutary result, so far as the surface is concerned, depends upon special vital influences exerted by the remedy upon the skin and reacting sympathies. This is exempli- fied by the profound effects of tartarized Antimony, and Ipecacuanha, the uselessness of hot water, and the f equent perniciotis results of Voi» i.—7. 98 GENERAL PRINCIPLES OF MEDICAL SCIENCE. the compound powder of Ipecacuanha, when free perspiration may follow the administration of either. The effect, therefore, depends hut very little upon the evacuation from the skin, as produced by what are called sudorifics.” {Institutes of Medicine.) It is proper to observe, that Opium may, and sometimes does effect cures in the hands of allopathists, when given as a specific. Its cura- tive virtues in delirium tremens and intoxication, even in large doses, are well known. In these instances, the remedy impresses directly the part diseased, and cures homoeopathically. It is quite true, that an infinitesimal quantity of the drug, properly prepared, will always prove more efficient, speedy and safe in accomplishing the object, and will not give rise to the unpleasant medicinal symptoms which ne- cessarily attend the employment of large doses; yet the fact must be conceded, that clumsy and unscientific cures are occasionally effected by the course alluded to. An interesting case is related by Pereira, illustrative of this: “Opium,” says he, “is sometimes employed by drunkards to relieve in- toxication. I knew a medical man, addicted to drinking, and who for many years was accustomed to take a large dose of laudanum, whenever he wras intoxicated and was called to see a patient.” The specific effects of the alcoholic stimulants and opium given during health, are exerted as remarked elsewhere, upon the same organ; and we should therefore expect that a malady caused by the excessive use of the one, might be cured by the specific action of the other. Tartarized Antimony.—This salt has been several times formally banished from the materia medica on account of its dangerous qualities, and as often restored after some accidental benefits wrere observed from its use. The faculty of medicine, at Paris, in 1566, and 1615, passed solemn decrees against it, as a virulent poison, and these decrees w ere even sanctioned by parliament, though afterwards formally reversed. ( Vale) Since this period, some have loudly extolled its virtues in the treat- ment of a great variety of diseases, while others have as earnestly con- demned its use, as deleterious in all cases. The distinguished professor Nathan Smith, in his essay on typhus fever, remarks: “I have seen many cases, in wrhich persons in the early stages of this disease were moping about, not very sick, but far from being well, and who upon taking a dose of tartrate of Antimony, wTith the intention of breaking up the disease, have been immediately confined to their beds? He arrives at the conclusion after much experience, that “ Tartar-emetic should not be used in this affection, even,at its commencement, and in the latter stages of the disease, that it is sometimes followed by fatal consequences.” In emetic doses, tartarized Antimony irritates the stomach, causes ALLOPATHY. 99 congestion, and sometimes inflammation of the lungs, attended with more or less constitutional disturbance. When it fails to produce emesis speedily, it often acts violently upon the bowels, giving rise to severe griping pains and watery evacuations. The tenderness of the stomach and intestines, and the constitutional disturbance which succeeds its emetic and cathartic operation, indicates the injury which these delicate structures have sustained. The primary impression of Antimony is not the only objection against its employment; for, like Calomel and Opium, it gives rise to numerous secondary symptoms in remote parts, which tend to aggravate in a serious manner any natural affection which may be present; one of the most important of these secondary evils is dilatation of the ventricles of the heart. Having witnessed this result in several instances, one of which occurred in my own family, my attention has been particularly directed to the subject, and I am fully of opinion that cases of this description, from the use of Antimony, are by no means unfrequent. Cinchona.—In intermittent fevers, general debility, and in certain stages of most other affections, Peruvian-bark and its preparations are usually employed by the old school. For the cure of the former, es- pecially, Quinine is the remedy upon which universal reliance is placed ; possessing the property, when used in large and repeated doses, of speedily arresting the chills and fever, it is constantly prescribed for this malady, without the slightest knowledge of its specific powers, and without any regard to the dangerous medicinal disorders, which it superinduces. All allopathists who have had much experience in the treatment of fever and ague, are aware that the mere suppression of the paroxysms by no means restores the patient to health; for in a great majority of instances, he lingers for months or even years in a diseased and mise- rable condition. In these cases it is probable that a medicinal affec- tion is induced by the remedy, so serious in its character, as to super- sede temporarily the primary one. This is evident, from the fact that after the effects of the medicine have somewhat subsided, the original disorder again generally makes its appearance. In some instances, however, the medicinal affection is so severe as to constitute a perma- nent disease, and thus entirely usurp the place of the fever. “ Experience,” says Dr. Paine, “ shows that, though bark and its al- kaloids, in large doses, will often arrest intermittent fever suddenly, such doses are liable either to induce some congestion, especially of the liver or of the mucous tissue of the stomach, or will aggravate and es- tablish some co-existing congestion ; and thus while the patient is for the present relieved of the fever, he is dismissed with an insidious local complaint that not only renders him a permanent invalid, (re- sulting often from indurated enlargements,) but which local malady 100 GENERAL PRINCIPLES OF MEDICAL SCIENCE. may, and often does become, in process of time, the exciting cause of another attack of fever. In respect to relapses, it is not unfrequent that, when intermittents are suddenly stopped by a large dose of Qui- nine, the paroxysms return as soon as the patient begins to exercise much, or to take his ordinary food.”—(Institutes of Medicine.) We should naturally suppose that these untowrard results wrould deter practitioners from using so frequently these dangerous remedies; or at all events, as rarely and in as small quantities as possible. On the contrary it seems to be peculiar to allopathy, that her ad- vocates take credit to themselves, when they succeed in administering this, as well as other medicines, in larger doses than any of their con- temporaries, without destroying their patients. Indeed, so far has this destructive system been carried, of experimenting upon disease, that the enormous quantity of a scruple, and even half a drachm of Qui- nine has been exhibited at a dose, and repeated several times a day. These monstrous quantities create (say Wood and Bache) “ gastro- enteritic irritation, nausea, griping, purging, head-ache, giddiness, fever, somnolency, in some cases delirium, in others stupor, &c.” Paine as- serts that he has witnessed many of these effects “ from five grains only ; ” yet, as patients sometimes live in spite of this treatment, many persist in adhering to these desperate innovations. There are many other medicines employed by allopathy in the treat- ment of disease, besides those to which we have alluded, but in general they serve only as auxiliaries. In this list may be ranked diaphore- tics, diuretics, expectorants, refrigerants, emmenagogues, emollients, errhines, &c., but the articles belonging to each of these classes, in a crude state and in large doses are liable to important objections. The fault of those medicines which operate specifically, like diruetics, emmenagogues, &c., in the hands ofallopathists, is the aggravation which they must necessarily cause, if the part acted upon be irritated or in- flamed. This objection will be clearly appreciated, when it is remem- bered how extremely sensitive to specific remedial impressions organs and tissues become during inflammation. The evils resulting from the use of those medicines which are not specifics, are, first, their inability to reach the seat of the disease, and secondly, the sympathetic derangement to which they give rise in various parts of the body, the direct tendency of which is to retard and counteract the recuperative efforts of nature. As an example of the first class, let us take the diuretic Copaibse as a remedy for gonorrhoea. In this example, the remedy doubtless im- presses directly the inflamed membrane of the urethra, but the impression is so violent, that either a decided increase of the inflammation ensues, or the discharge is suddenly suppressed, and some other org&n, as the bladder, kidneys, testicles, or lungs, takes on diseased action. Indeed, ALLOPATHY. 101 we are decidedly of opinion, that not one genuine case of virulent go- norrhoea can be adduced, where a safe and permanent cure has been effected by large doses of this balsam. A not unfrequent effect of Copaibse in moderate quantities, is to ex- cite serious disorder of the lungs. This consequence I have often witnessed, and I have a patient at this time, who assures me, that he is unable to take a single dose of it, without being afflicted with a pain in his chest and cough. Gastric and intestinal disturbance, also usually result from its use. In some instances, a troublesome eruption makes its appearance, ren- dering it necessary to discontinue its employment for a time. And yet, with all of these artificial consequences, the disease is very rarely, if ever, cured by this nauseous substance. Diaphoretics were introduced into practice by the advocates of the humoral pathology, under the supposition that their sweating qualities would aid nature in throwing off the morbid humors. When the hypo- thesis universally obtained, that fevers were caused by an excess of one of the four humors, blood, phlegm, and black and yellow bile, and that this superabundance must be expelled through the pores of the skin, kidneys, &c., it was a rational deduction that the employment of dia- phoretics and diuretics should conduce essentially to aid nature in the cure. But when more correct ideas in regard to the nature and seat of diseases were introduced, and medical men had learned that spontaneous sweating diuresis, discharges of blood, diarrhoea, &c., in the latter stages of diseases occurred in consequence of a natural amendment or a sud- den prostration in the powers of the affected parts, and not as an effect of the medicines, it is a matter of surprize that these uncertain reme- dies should have been retained. The late Prof. JV. /Smith says: “As there is more or less sweating in the decline of most febrile diseases, and, as a general perspiration is often accompanied wdth other symptoms of amendment, it has been looked upon as the natural cure of the disease. Under this impression, it has been a pretty universal practice to encourage sweating; but with respect to the grounds upon which this practice is founded, it is a ques- tion whether the effect has not, in this case, been mistaken for the cause; that is, whether the sweating is not the effect of the amend- ment, rather than the cause of it; and, if so, it is still more question- able whether sweating, produced by art in the beginning of the disease, wrould be attended with good effects. In all cases, where I have seen this sweating regimen adopted, the practice has been obviously im jurious.” Many other eminent professors, as may be readily proved, entertain similar views in regard to this subject. 102 GENERAL PRINCIPLES OF MEDICAL SCIENCE. Physiology teaches us, that no unusual disturbance, no inflammation and no functional derangement can accrue to any part of the body, whether by a moral, physical, morbific or medicinal agent, without be- ing followed by secondary sympathetic symptoms in remote parts, more or less severe according to the violence of the exciting cause. The stomach and bowels more especially, being the grand centre of junction of the ganglionic system of nerves, are so intimately connected with all parts of the economy, that disturbances at either of these points are reflected through the sympathetic nerves upon remote healthy struc- tures, thus complicating to a serious and often fatal extent, any dis- order which may already be present. There is scarcely any part of the machine, which is not called into morbid sympathetic action by derangements of the stomach and in- testines. Even the presence of bile or acid, in unusual quantities, causes pains in the head and limbs, nausea, and other affections of a distressing nature, until the offending substances are removed. All of the organs and tissues are so closely connected by the nervous system, that it may be laid down as a general rule, that no disorder can happen to one part without implicating more or less other parts, whether diseased or healthy. {Muller’s Physiology.) “A particular state of one organ, such as inflammation, or a secreting action in it, often causes the production of a similar state in other parts. The principle of the balance of sympathy teaches us, how we must avoid aggravating the morbid condition of one organ by the means we apply to another.” How reasonable, then, to expect that artificial medicinal inflammations of the sensitive structures of the economy should give rise to secondary affections of a grave and permanent character. In conclusion, the theoretical and practical doctrines of allopathy may be briefly summed up as follows : 1. In the rude ages of the world, when the arts and sciences were in their infancy,—when vague, indefinite and absurd notions were enter- tained respecting diseases,—when anatomy, chemistry, physiology, pathology, botany, and even correct methods of induction wTere entirely unknown,—when the imaginatians of men, instead of ascertained facts, were appealed to in establishing theories,—and when systems of prac- tice were founded upon merely fanciful conjectures,—then it was that blood-letting, cathartics, diaphoretics, diuretics, refrigerants, revulsives, derivatives, counter-irritants, and most of the other remedies of allopathy made their first appearance. As the pathological doctrines of this period were all entirely erroneous, it is but fair to conclude, that their therapeutical inferences must have been equally incorrect. 2. Whatever may have been the changes in respect to the theory of disease, from age to age, long established customs, the force of habit, ALLOPATHY. 103 education, prejudice, &c., have served to retain until our own period, most of the violent, unnatural and pernicious methods of treatment, in- vented and adopted by the founders of medicine. 3. At the present time, every thing pertaining to the theory and practice of the old school is indefinite, obscure and uncertain. Scarcely two different allopathists entertain the same views in regard to patho logy, and no one can determine beforehand with any kind of certainty precisely what effects his medicine will produce’; yet in the treatment of nearly all cases, Venesection, Calomel, Opium, and Antimony are empirically, and we might almost say, universally employed, in quantities too great to he beneficial or safe. In those cases, where refrigerants, diuretics, expectorants, &c., are used, they can only he looked upon as auxiliaries, and are usually ad- ministered without any accurate knowledge as to whether they promote or retard the designs of nature. 4. Owing to the absence of any generally received or consistent theory of disease, allopathists are obliged to prescribe at random. They strike at the name, and not at the seat of the maladies, where alone re- medies can prove efficient. Thus it is, that patients are so often reduced to the lowest point by medicines, while the disease continues its pro- gress unchecked. 5. Lastly, there is every reason to believe, that the production of violent artificial diseases in healthy structures, for the suppression of natural maladies, is, upon the whole, far more productive of deleterious than of beneficial consequences. The effort, to discover specific remedies for individual diseases, is not yet abandoned; but it is restricted to the making of experiments upon the sick, and results only in infrequent cures, which are never satisfactory and which can not he repeated or imitated in subsequent cases. Hahnemann, in his essay, entitled: Examination of the Sources of the Common Materia Medicaf (Lesser Writings, p. 748), with a masterly and irresistible logic, that has never been surpassed, shows that such experimentation is nothing but crude empiricism, and that, though it has been in vogue for some thousands of years, it has never yet given us a single reliable specific. A great part of the medicine, given with the pretence of curing dis- ease, is not expected to cure, but to palliate, to cover up the loud complaints that the organism is everywhere uttering for help. Dr Parrish, Lecturer on Pharmacy, (Philadelphia) said recently: “ The prevailing doctrines among medical men at this time, direct, that a large per-centage of all the prescriptions now made contain Opium, Morphia, or Hyoscyamus.” Five years ago,he ascertained, that his own prescrip- tions averaged thus : Opiates 24 per cent; Mercurials 23 per cent; 104 GENERAL PRINCIPLES OF MEDICAL SCIENCE. Iodine and Iodide of Potassium 6 per cent; Cinchona and its al- kaloids 9 per cent. These were the proportions in the written prescriptions. Of the unwritten prescriptions the proportion of Opium was larger, as Opium in some form was in every house. Second in importance is Ilyoscyamus, Then, Conium, Belladonna, Stramonium, Cannabis-indica. Allopathy is a mere collective title of all the various modes of treat- ment not homoeopathic, and has no pretensions to a place among the definite curative modes by specifics. {Muller.) The more recent theory of specific or substitutive action teaches, that diseases even widely dissimilar may supersede each other, or that one may supersede another: we have examples of such supersessions, and of a new and not similar disease complicating an old one, but not of removing it. “ In fact, when the latter event takes place at all, it is only when the new disease approaches to the required degree of homoeopathi- city. In fine, the real fact of the matter we apprehend is simply this, that the degree of homoeopathicity that suffices for cure is not accurately fixed; and, as we recede from complete homoeopathicity, a certain margin is left within which specifics given in more massive doses may still have curative effects.” Within this margin may room enough be found for the spe- cificers, Rademacherians and Trousseauist substitutivists. But beyond that we protest against allowing any such method as an allopathic alterative one any positive existence at all. The great discovery of Hahnemann, viz., the positive homoeopathic law of specifics must not be let down and diluted and refined away, by giving it only a place as one of a sliding scale of specific actions, all on pretty much the same footing. No ! if we are compelled to admit as matter of fact that there are other actions of medicine, which we must on exceptional oc- casions make use of, such as the antipathic or revulsive, let us say so plainly, and not attempt to shade them off into the homoeopathic. {Muller.) In view, therefore, of the present condition of the medical art, we most earnestly request the allopath to pause or reflect deeply and seriously, before he rejects finally the most important discoveries in the art of curing disease, that have been made in ancient or modern times. Let him remember that a high responsibility attaches to his po- sition,—that the welfare, happiness and lives of his patients hang upon his judgment and decision,—and that an improper exhibition of re- medies may so complicate and aggravate the natural disease, as to con- sign his patient to a premature grave. Let him look about, candidly and impartially, and see if there are really no improvements in the healing art since the times of Hippocrates and Galen. Let him submit new discoveries and new doctrines to a rigid practical test, and decide from the results,—from the cures effected,—wThat system is most correct HOMOEOPATHY. 105 and best calculated to promote the welfare of the human race. Let him no longer reverence ancient doctrines and ancient names, simply on account of their antiquity, but seek after truth alone, whether of ancient or modern discovery, and found his practice only upon this certain basis. HOMCEOPATHY. The Discovery of the Homoeopathic Mode of treating disease is thus announced by Hahnemann: * “ By observation, reflection, and experiment, I discovered, that, in opposition to the old allopathic method, the true maxim; To effect a mild, rapid, certain, and perm anent cure, choose in every case of disease, a medicine which can itself produce an affection similar (oyoLov iraOog) to that sought to be cured. “ Hitherto no one has ever taught this homoeopathic mode of cure, no one has practiced it. But if the truth is only to be found in this method, as I can prove it to be, we might expect that, even though it remained unperceived for thousands of years, distinct traces of it would yet be discovered in every age? “And such is the fact. In all ages, the patients who have been really, rapidly, permanently, and evidently cured by medicines, and who did not merely recover by some fortuitous circumstance, or by the acute disease having run its allotted course, or by the powers of the system having in the course of time gradually attained the preponderance, under allopathic and antagonistic treatment, for being cured in a direct manner differs vastly from recovering in an indirect manner.—Such patients have been cured solely, (although without the knowledge of the physician), by means of a (homoeopathic) medicine, which possessed the power of producing a similar morbid state.” When Hahnemann first promulgated to the world his pathological and therapeutical views, their novelty, their entire variance from all preconceived opinions, and their alleged superiority over all other systems, when applied to the practice of the healing art, induced physicians to suppose the man mad, and his ideas the offspring of a disordered imagination. It was difficult to conceive that acute maladies could be cured without venesection, emetics, cathartics, sudorifics, refrigerants, altera- tives, and counter-irritants and on this account the great discoveries of the father of homoeopathy were for many years coldly received, and his arguments answered only by impudent sneers or senseless ridicule Like the illustrious Fulton, who—when he announced to his country- men the powers of steam, and first applied this agent to the propulsion * Organon.—Introduction. 106 GENERAL PRINCIPLES OF MEDICAL SCIENCE. of a vessel—was declared, even by his nearest friends insane, and liig projects visionary: like Harvey, the discoverer of the circulation of the blood, who was bitterly assailed “by the bigotted abettors of old- established systems, with whispers, innuendoes, and controversial writ- ings, and himself pronounced a reckless innovator, and unworthy of public confidence as a practitioner; like Galileo, who, after demonstrat ing the truth of the Copernican system was persecuted by his rivals and twice compelled by the inquisition to abjure a system which he knew to be correct; like Columbus, Newton, Locke, Jenner, and many other benefactors of the human race, Hahnemann has been aspersed, and his doctrines, like theirs, have been ridiculed, misrepresented, and contemned: but time has cast all the columniators of Columbus, of Galileo, of Newton, of Locke, of Harvey, of Jenner, of Fulton, into a deserved oblivion, while the names of these eminent persons stand high on the roll of fame, and their discoveries remain to benefit the world. Brief Exposition of the Homoeopathic Method of Treatin g Dis- ease.—The following truths are established by reason and experience : 1. There is nothing for the physician to cure in disease but the suffer- ings of the patient. The changes in his state which are perceptible to the senses comprise what is known by “the totality of the symptoms by which the disease points out the remedy it stands in need of.” These changes are internal as well as external, and the physician takes into his enumeration of symptoms, not only all that appear upon the sur- face, but all the pathological changes which he knows to be going on internally. 2. Disease can not be converted into health but by the aid of medi- cines and agencies which are capable of producing similar disease- symptoms. The powers of a given remedy to produce similar symptoms are best learned through experiments on healthy individuals, so far as experimenting may safely go in such researches: where these neces- sarily terminate, we may learn their further powers from the accidental uses and abuses of the same agents in allopathic practice and cases of poisoning. 3. “According to every known fact,” says Hahnemann, “it is impos- sible to cure a natural disease by the aid of medicines which have the faculty of producing a dissimilar artificial state or symptom in healthy persons. Therefore the allopathic method can never effect a real cure. Even nature never performs a cure or annihilates one disease by adding to it another that is dissimilar, be the intensity of the latter evtr so great.” c 4. “Every fact serves to prove that a medicine capable of exciting in healthy persons a morbid symptom opposite to the disease to be cured, never affects any other than momentary relief in disease of long standing, without curing it, and suffers it to reappear after a cei'tain HOMOEOPATHY. 107 interval more aggravated than ever. The antipathic and purely pallia- tive method is, therefore, wholly opposed to the object that is to he attained, where the disease is an important one, and of long standing.” 5. The homoeopathic method which employs against the totality of the symptoms of a natural disease a medicine that is capable of exciting ii< healthy persons symptoms that closely resemble those of the disease itself, is the only salutary method. It always annihiliates disease, or the purely dynamic aberrations of the vital powers, in an easy, prompt, and perfect manner. In this respect nature herself furnishes the example, when by adding to an existing disease a new one, that resem- bles it, she cures it promptly and effectually. “ A new and more intense disease suspends a prior and dissimilar one already existing in the body, only so long as the former continues, but it never cures it. If the new disease, which is dissimilar to the old be more powerful than the latter, it will then cause its suspension until the new disease has either performed its own course or is cured; but then the old disease reappea/rs. We are informed by Tulpius (Obs. Lib. 1. Obs. 8.) that two children having contracted tinea, ceased to experience any further attacks of epilepsy to which they had till then been subject: but as soon as the eruption of the head was removed, they were again attacked as before. Schopf saw the itch disappear when scurvy manifested itself, and return again after the cure of the latter disease. (Hufel. Journ. XV. 2.) A violent typhus has suspended the progress of ulcerous phthisis, which resumed its march immediately after the cessation of the typhoid disease (Chevalier). When madness manifests itself during the pulmonary disease, it effaces the phthisis with all its symptoms; but then the pulmonary disease again rears its head and kills the patient. (Reil. Memorabilia). When measles and small-pox exist together, and have both attacked the same child, it is usual for the measles which have already declared them- selves, to be arrested by the small-pox which bursts forth, and not to resume their course until after the cure of the latter; on the other hand, Manget has also seen the small-pox, which had fully developed itself after inoculation, suspended during four days by the measles which intervened, and, after the desquamation of which, it revived again to run its course. The eruption of measles on the sixth day after inocula- tion has been known to arrest the inflammatory operation of the latter, and the small-pox did not break out until the other exanthemata had accomplished its seven days “course.” (J. Hunter on the Venereal Disease) In like manner vaccine disease and scarlatina have been seen to suspend each other, the stronger of the two expelling for the time the other. “ It is the sam e in all diseases that are dissimilar: the stronger one suspends the weaker (except in cases where they blend together, 108 GENERAL PRINCIPLES OF MEDICAL SCIENCE. which rarely occurs in acute diseases:) but they never cure each othd reciprocally.” “In the same manner, violent treatment with allopathic remedies never cures a chronic disease, but merely suspends it during the continuance of the powerful action of a medicine incapable of exciting symptoms similar to those of the disease: but afterwards the latter re- appears, even more intense than before.” “Or the new disease, after having acted for a considerable time on the system, joins itself finally to the old one, which is dissimilar, and thence results a complication of twro different maladies, either of which is incapable of annihilating or curing the other.” In this case each occupies the particular region of the economy, installing itself in those organs writh which it sympathizes, and abandoning the others to the diseases that are dissimilar. Thus venereal and psoric diseases, being dissimilar, “ are incapable of annihilating or curing each other. The condition of the patient is worse under the two diseases than he would have been under either of them alone.” (Organon § 40, p. 112.) When a medicinal disease is excited which is similar to the existing one, and is stronger than it, the new disease supersedes the old one. Two diseases, says Hahnemann, “ that differ greatly in their species, but which bear a strong resemblance in their development and effects, —that is to say, in the symptoms which thgy produce, always mutually destroy each other when they meet together in the system. The stronger annihilates the weaker. Two dissimilar diseases may co-exist in the body, because their dissimilitude wrould allow of their occupying two distinct regions.” But when the diseases are similar, the stronger disease exercises an influence upon the same parts as the old one, and even throws itself, in preference, upon those which have till now been attacked by the latter; so that the old disease, finding no other organ to act upon is necessarily extinguished. Or, to express it in other terms, as soon as the vital powers which have till then been deranged by a morbific cause, are attacked with greater energy by a new power, very analogous to the former, but more intense, they no longer re- ceive any impression but from the latter, while the preceding one, re- duced to a state of mere dynamic power without matter, must cease to exist.”—(§ 45.) “ Of any two diseases wdiich occur in the ordinary course of nature, it is only that one whose symptoms are similar to the other which can cure or destroy it. This faculty never belongs to a dissimilar disease. Hence the physician may learn what are the remedies with which he can effect a certain cure, that is to say, with none but such as are homoeopathic.” A remedy that is perfectly homoeopathic cures the disease with- out any accompanying ill effects; and a disease that is of no very HOMOEOPATHY. 109 lon<; standing ordinarily yields, without any great degree of suffering, to a first dose of a well-selected remedy. When a perfectly homoeo- pathic remedy acts upon the body we see nothing more than symptoms analogous to those of the disease laboring to surmount and annihilate these latter symptoms by usurping their place. The remaining symp- toms, caused by the medicinal substance, which are often numerous, and correspond in no respect with the existing malady, scarcely ever show themselves, and the patient improves from hour to hour. The remedy having expended its force in those portions of the organism that were already a prey to existing disease, and in these parts exerted that specific action by which it extinguished the original disease. But there are a few exceptions to this general truth. “There is no homoeopathic remedy, however suitably chosen, that does not (espe- cially in a dose not small enough,) produce at least during its action, some slight inconveniences or fresh symptoms in very sensitive and ir- ritable patients. In fact it is scarcely possible for the symptoms of the medicine to cover those of the malady with as much precision as two triangles writh equal sides and angles. But these differences, which are of little importance in a case that terminates in a short time, are easily effaced by the energy of the vital principle, and the patient does not perceive it himself, unless he is excessively delicate. The re- establishment of health goes forward, notwithstanding, unless impeded by the influence of heterogenous medicinal agents upon the patient, errors of regimen, or excitement of the passions.—(Hahnemann, § 156.) When a true homoeopathic remedy in small dose has been given, it quietly annihilates the acute disease wdiich is analogous to it, without exciting new and non-homoeopathic symptoms; but it often happens that it produces at the end of one or two hours (according to the dose), a state something less favorable, which resembles the original disease so closely, that the patient supposes the primitive affection aggravated. But in reality it is nothing more than a medicinal disease, extremely similiar to the primitive one, and rather more intense in its nature. This trifling homoeopathic aggravation of the malady during the first few hours may be accepted as a happy omen that the disease will soon be cured, perhaps even with the first dose. The medicinal disease is similar to the other, but more intense than the one it is intended to cure. The smaller the dose of the homoeopathic remedy, the slighter the apparent aggravation of the disease will be, and proportionably of shorter duration. In a discussion in the Societe Med. Homoeop. de France, Feb. 20, 1860, M. Cretin thus stated what he called the double principle enun- ciated by Hahnemann. 1. The curative effect is so much the more uncertain and rare in 110 GENERAL PRINCIPLES OF MEDICAL SCIENCE. proporticn as the dose induces more marked and more numerous patho- genetic symptoms. (Superior limit.) 2. The curative effect is so much the more sure and constant in pro- portion as the dose approaches that which would excite the slightest aggravation of existing symptoms. (Inferior limit.) The real nature of homoeopathic cures is thus explained by Fletcher on the Brunonian theory: The primary action of stimuli, and therefore of all specifics, as well as of all other positive agents, is in reality two- fold ; and in all organic diseases, such as inflammation and its conge- ners, fevers, increased secretion, &c.,—consists in, first, a stage of ex- citement, with constriction of the capillary vessels, followed by indirect debility with dilatation of the capillaries, and increased secretion ac- cording to its kind. When the homoeopathic cure takes place, the disease is in the stage of indirect debility, and the medicine exerts upon it its action, viz., that of a stimulus, and thus the cure takes place by antipathic action. But this must not be confounded at all with that action in the sense of the allopathists, for it does not refer with them to this view of the ultimate nature of the action of medicine, but to its broad meaning as primary and secondary on the healthy body.

TV DERIVATIVES; REVULSIVES; COUNTER-IRRITANTS The curative powers of drugs, says Hahnemann, are in no wise dis- coverable in themselves; and the pure experiments which have been made, even by the most skillful observers, exhibit nothing to our view which could be capable of rendering them medicines or curative re- medies, except the faculty they possess of producing manifest changes in the general state of the human economy, particularly with persons in health, in whom they excite morbid symptoms of a very decided character. We ought to conclude from this, that when medicines act as remedies they can not exercise their curative virtue by the faculty which they possess of modifying the general state of the economy and giving birth to peculiar symptoms. Consequently we ought to rely solely upon the morbid appearances which medicines excite in healthy persons,—the only possible manifestations of the curative virtues which they possess, in order to learn what malady each of them pro- duces individually, and at the same time what diseases they are capable of curing.” (Organon, p. 21.) “Medicinal substances manifest the nature of their pathogenetic power, and their absolute, true action on the healthy human body, in 112 GENERAL PRINCIPLES OF MEDICAL SCIENCE. the purest manner, when each is given singly and uncombined to healthy individuals. And thus we obtain the pure result of the form of disease that each of these medicinal substances is capable of producing ab- solutely, and in itself on the human body.” {Hahnemann’s Lesser Writings, Mar Gy’s Edition, p. 452.) “It is impossible that the alterations in man’s health, which medicines are capable of producing, can be known and observed more purely, cer- tainly and completely by any other method in the world than by the action of medicines upon healthy individuals; indeed there is no other way conceivable, in Avhich it were possible to obtain experience that shall be at all of an accurate character. Even when given in human diseases, in order to ascertain their effects, the peculiar symptoms which were solely due to a medicine can never be distinctly recognized, never accurately distinguished amid the tumult of morbid symptoms already present, so as to admit of our ascertaining which of the changes effected were owing to the medicines, and which to the disease.” # PRIMARY AND SECONDARY ACTION OF DRUGS. Homoeopathy teaches that the impressions which drugs produce upon the organism, in health and in disease, are analogous in their character. But there is this important difference between healthy and diseased structures, that large quantities of the drug are required to produce appreciable impressions upon the former, while the susceptibility of the latter is so morbidly augmented that the most minute atoms of the medicine are instantly effective. Not only so, but even the natural material stimuli of the structures can not be tolerated, but become im- mediate and additional causes of disease, and, if persisted in, of fatal disorganization. If then, wTe desire to know the precise effects of drugs in disease, it is necessary to prove them by taking when in health doses sufficiently large or so often repeated as to affect the structures sen- sibly and decidedly. Even if contraria contrariis opponenda be adopted as the law of practice, this is an important discovery, for we may then administer the remedies with a full knowledge of the parts they impress and of the exact symptoms they induce, and thus remove allopathy a single step from empiricism. Some eminent writers of the old school have distinctly shown the importance of this subject. Thus, Dr. Paris, in his Materia Medica, remarks, “that observation and ex- periment upon the effects of medicine are liable to a thousand fallacies, unless they are carefully repeated under the various circumstances of health and disease, in different climates, and on different constitutions.” Professor Dunglison {On New Remedies, page 7) says: “to treat disease methodically and effectively, the nature of the actions of the * Hahnemann’s Lesser Writings, 721-722 pp. PRIMARY AND SECONDARY ACTION OF DRUGS. 113 living tissues, in both the healthy and morbid conditions must he cor- rectly appreciated; the effects which the articles of the Materia Me- dica are capable of exerting under both those conditions must he known from accurate observation, and not until then can the practitioner pre- scribe with any well-founded prospect of success.” Pereira assures us, “ that in order to ascertain the action of remedial agents on the living body, it is necessary that we examine their influence both in healthy and diseased conditions. For by the first we learn the positive or actual power of a medicine over the body; while, by the second we see how that power is modified by the presence of disease.” (Materia Medica and Therapy Vol. I., p. 126.) Other equally distinguished allopathic writers now entertain the same views upon this point, but without taking into consideration some very important circumstances connected with the provings. We have reference to the great fact inculcated by Hahnemann, that all drugs ex- ercise upon tbe organism two effects, a primary and a secondary, and that these secondary effects are always the reverse of the primary. A knowledge of this truth will enable us to classify both the primary and the curative results of medicines, and thus more clearly to ap- preciate the phenomena which should guide us in their application. The primary symptoms make their appearance soon after the medicine has been taken into the stomach, and continue for a longer or shorted period, according to the magnitude of the dose and the condition of the general health; after which they disappear, and the secondary or op posite series of phenomena manifest themselves and remain until the organism recovers its equilibrium. But in a few instanc-es the power of drugs is displayed in such a manner that these primary or secondary effects appear in alternation for a considerable time, when the primary symptoms yield to the secondary, or serious organic derangements ensue. The mode of operation in these instances is probably analogous to that of the miasm of intermittent fever, in producing alternate chills and heat. Medicines of this description are termed poly crests. No one who has candidly tested the operation of drugs, with reference to this law, can for an instant deny its truth and importance; and the law applies not only to large doses of drugs, but to every other cause which unduly impresses the structures : that is in such a manner as to disturb that healthy balance in the operations of the organs whiclkcon- stitutes health. Let us examine the ordinary effects of cathartics in health: First, the mucous membrane of the intestinal canal is irritated or inflamed, and the natural consequence of inflammation follows in the form of increased mucous and serous secretion, increased peristaltic action, and a painful and loose state of the bowels : this is th% primary effect. After several thin discharges from the bowels, a debility and a depression of the parts occur, the degree of which is proportioned tc VOL. i.—8. 114 GENERAL PRINCIPLES OF MEDICAL SCIENCE. that of primary irritation; the peristaltic action becomes impaired oi suspended, and constipation results as the secondary effect of the drug There is no exception to this rule, unless the cathartic operates so violently as to produce a permanent inflammation and disorganization of the mucous membrane, in which case the primary symptoms may be continuous and constitute a permanent affection. Even in cases of this kind, however, partial reactions sometimes occur during the course of the malady, and secondary symptoms are manifested, in the form of constipation alternating with diarrhoea. These violent primary symp- toms rarely continue beyond a few days without resulting in serious structural lesion, or a healthy and permanent reaction. The primary effects of Opium, in large doses, are to induce sleep, lessen nervous and muscular sensibility, cause agreeable dreams, and diminish or suspend all of the secretions, with the exception of per- spiration, which is augmented. If the quantity taken has been mode- rately large, a pleasurable excitement for a short time precedes the soporific influence as a primary symptom. These first results continue from twelve to forty-eight hours, according to the magnitude of the dose, when the organism reacts: the exhilaration is succeeded by de- pression, the sopor by constant and prolonged wakefulness, morbid irri- tation of the whole system, a return in preternatural quantities of all the secretions, which had been suspended, and a suppression of the cutaneous secretion, which had been morbidly augmented; and the secondary effects of the drug are thus manifested. So long as diuretics continue to irritate the kidneys, they are for- cibly stimulated to pour out an unusual quantity of urine; but as soon as the specific is omitted, the organism reacts against the temporary irritation set up by the medicine, and a corresponding diminution of the urinary secretion follows, until the organ recruits from the pre- vious overaction, and the disturbed equilibrium is restored. The primary operation of stimulants gives rise to an exaltation of the mental and physical powers, while a corresponding depression and abasement invariably result as secondary consequences. The primary operation of Digitalis in large doses, is to retard the action of the heart and arteries. The reaction of the system against the drug, or the secondary effect, is an augmentation of this action. The primary symptoms caused by Aconite are intenser action of the circulatory vessels: the secondary consequence consists of a in- duction of the pulsations, in some instances as low as thirty-five in the minute. The primary effect of intense cold is to stimulate and invigorate the whole system; and the secondary results are loss of muscular and mental energy, stupor and death. All drugs, whatever may be the special nature of their action, give PRIMARY AND SECONDARY ACTION OF DRUGS. 115 rise in every part of the organism where this action manifests itself, to two orders of symptoms, which are generally, if not always, opposed to each other. Hahnemann attributed no other symptoms to the drugs directly, except those which he had seen develop themselves under their influence, and which he therefore called “primary symptoms.” Whereas he considered as simple reactions of the organism all those symptoms that succeeded the former, and which he therefore designated as “secondary.” Teste considers it not yet perfectly settled that the secondary symptom is always the contrary of the primary. (Materia Med., p. 48.) Hahnemann says: Every agent produces, more or less, “some notable change in the existing state of the vital powers, or creates a certain modification in the health, of longer or shorter duration: this change is called th% primitive effect. But our vital powers tend always to oppose their energy to this influence or impression. The effect that results from this, and which belongs to our conservative vital powers and their automatic force, bears the name of secondary effect or re- action.” Examples, The Primary Effect of dipping the hand in cold water is to make it hotter than in the common state. Violent exercise causes ex- treme heat. Wine stimulates and heats the body. An arm held for some time in freezing water becomes cold and pale. Strong coffee stimulates the phy- sical and mental powers. Opium excites somnolence or deep stupor. Opium causes first constipation. Purgatives increase the action of the bowels. Secondary Effect. After drying it becomes colder than before. Shivering and cold follow over- heat. Next day the slightest current of air produces chill. Being withdrawn and dried it becomes hotter than the other. It leaves behind it heaviness and drowsiness which lasts long. More difficult to fall asleep when its action is entirely expended. Diarrhoea follows the constipa- tion. Constipation follows the purg- ing. This law of primary and secondary action applies not only to ww- dicinal, but to a large proportion of morbific agents. On this suppo- sition we may readily account for the remissions and exacerbations which are observed in most fevers. It is only when the morbific in- fluence has been very active and the resulting inflammation violent, that no reactions or remissions occur. It may nevertheless be set down as general law, that no structure of the human body can be called into 116 GENERAL PRINCIPLES OF MEDICAL SCIENCE. preternatural action, or stimulated beyond a given point, without a speedy tendency to reaction on the part of the organism. In severe forms of disease, this reaction may not be apparent for weeks, and per- haps until organic lesion occurs ; yet, sooner or later, some reaction, with secondary symptoms, manifests itself. There is a healthy point in the functional actions of the organs—an equilibrium, if we may be allowed the expression, of the respiratory, circulatory, digestive, absor- bent, assimilative, secretory and excretory functions—which can not be disturbed with impunity. Stimulate one of these beyond its natural point, and a corresponding depression must necessarily ensue before the normal balance is restored. E ach tissue possesses only a definite amount of resisting power, and therefore every undue expenditure of this power entails future debility. Nature is constantly striving to maintain the functions in their natural condition, and this she accom- plishes by inducing in the different parts a reaction the reverse of the disturbing cause, and bearing an inverse ratio to this cause. The amount of strength and resisting force which is acquired from the food, &c., is fixed and definite; and this force is expended in limited and definite quantities throughout the economy, and thus secures the healthy per- formance of the functions. The practical deductions which legitimately arise from these views of this subject, are of the most interesting character, as regards the application of remedies ; for if the ideas which have here been adduced are correct, it is plain that the antipathic doctrine of cure is erroneous, while the truth of the homoeopathic becomes equally apparent. SUSCEPTIBILITIES OF ORGANS AND TISSUES TO THE INFLUENCE OF REMEDIAL AGENTS, VASTLY GREATER IN DISEASE THAN IN HEALTH. One of the principal arguments which has been adduced against Hahnemann’s system of Therapeutics is the supposed fallacy of judg- ing of the effects of medicines in disease, from their operation in health. It is considered that the modifications which occur in what are termed the “ vital properties” of parts, in a state of disease, also alter the action of remedical agents in a corresponding manner. The fact is incontrovertible, that tissues in a state of inflammation, do acquire properties very different from what they possess in the nor- mal state, but respecting the nature of these acquired properties, numerous facts go to prove, firstly, that the parts actually inflamed, be- come extremely sensitive to the impressions of specific remedies ; and, secondly, that the facility of absorption is promoted throughout the whole system. The recent experiments of Miiller and Matteucci have de- monstrated the fact, that in proportion as the tone of the nervous and INFLUENCE OF REMEDIAL AGENTS ON ORGANS AND TISSUES.' 117 muscular systems becomes impaired, or inflammation obtains, up to a certain point, just in the same ratio will absorption be promoted, and foreign agents exercise their influence. We have seen that inflammation consists in a “ congestion of the capillaries” induced by debility and the want of resisting power in these structures to exclude the arterial blood, and that the effects of inflammation of a particular organ upon the general system, are las- situde, pains, and other symptoms which indicate diminished nervous and muscular energy. That condition, therefore, which is termed erethism, is not, as is sometimes supposed, indicative of increased nervous energy, but results directly from loss of strength. In health the capillary vessels possess the power of excluding all of those constituents of the blood except the colorless fluid which is their natural stimulant. Although the capacity of these minute tubes is sufficiently large to admit the red globules with ease, yet they are en- dowed with a peculiar property which enables them to resist their entrance. Any cause, therefore, capable of impairing this natural irritability, becomes a source of debility and inflammation. It has been proved that, in health, most medicinal snbstanccs may become absorbed into the blood ; but unless they possess some pecu- liarly noxious qualities, they will act upon those parts for which they have a specific affinity, and be throwm off" in the form of excretions, causing in their passage through the structure on which they act, only a slight and perhaps unappreciable irritation. When taken in disease, these same substances are absorbed with far greater facility, and exercise the same specific affinity for parti- cular parts as in health ; but with the difference, that they make im- pressions upon the inflamed tissues, far more energetic and strongly pro- nounced, than when taken in a healthy state of the organism. Nor is is this augmented susceptibility to the influence of remedies, confined to the tissues primarily affected, but the whole system becomes far more impressible than during health. It is a well established law, that no one structure can be inflamed without giving rise secondarily to sympathetic symptoms in other parts of the economy. It matters not whether the paxt affected, be the lungs, stomach, skin, or any other structure, the whole system may be ultimately disordered, through remote contiguous or continuous sympathy. The connection between the different parts of the human body, through the media of the sympathetic nerves, is so close and direct, that no organ can be acted on by a morbific agent, without developing secondarily sympa- thetic symptoms more or less violent, according to the nature of the agent, the severity of the primary impression, and the constitution of the individual. 118 GENERAL PRINCIPLES OF MEDICAL SCIENCE. All of the organs are so designed and constructed by the Supreme Architect, that, in health, a certain harmony of action prevails through- out every part of the machine, causing every function to be executed with uniformity, so that no disturbance can accrue to any single part without impairing this healthy equilibrium. Dr. Paine, in speaking of this subject, presents the following views which will be found to coincide very nearly with the doctrines of Hahnemann; we only wonder that the practical deductions of these two distinguished authors should differ so materially: “ It appears, therefore, to be a most important law, that morbid states call into operation that function of sympathy among organs, which in their natural state manifest but feeble, and perhaps no direct relations whatever ; and that in consequence of morbid changes, remedial agents will operate sympathetically through the stomach, &c., upon remote parts, when they would have no such effect in the healthy state of the organs. New vital relations being developed by disease, our remedies continue to operate through those acquired relations so long as they exist.” Again, “ In proportion, therefore, as the susceptibility of the system at large is increased by morbid changes, or predisposed by morbific in- fluences, so, in a general sense, will the alterative action of remedial agents be felt in a corresponding manner.” Again, “ It is one of the most important law's in medicine, that the susceptibility of tissues and organs to the action of remedial agents, is more or less affected by disease. Many agents which operate powerfully in certain morbid states, and in certain doses, both locally and sympathe- tically, may be perfectly inert in the natural states of the same organs.” Finally, “It is worthy of repetition, that such is the analogy between morbific and remedial impressions, that the organs which sustain the former are rendered susceptible of the latter, when they might other- wise be insensible to the same remedial agents, in their appropriate doses. Take many of the most powerful agents, Arsenic, tartarized Antimony, Iodine, &c., and when administered in certain small and repeated alterative doses, they bring about the cure of the most obsti- nate and formidable conditions of disease ; while the same doses may not manifest any action upon the system, or on any part of it, under circumstancss of health. This manifestly depends upon an increased susceptibility of the organic properties in their diseased conditions, to the action of foreign agents, and upon an increased disposition to under- go changes. This law, w'hich unfolds a principle latent in health, and by which morbid organic properties acquire susceptibilities to salutary influences from agents which in health would either produce no effects, or lead to untoward results, and its ally, the great recuperative prin* INFLUENCE OF KEMEDIAL AGENTS ON ORGANS AND TISSUES. 119 ciple, impose the highest obligation upon physicians to become medical philosophers.”—(Paine's Institutes of Medicine.) Most of the positions laid down by Dr. Paine in the above quotations are doubtless correct; but. in all his inductions, he is laboring undei an important error in supposing that morbific and remedial agents exercise their influence only upon certain immaterial principles 01 vital properties. • Can it be supposed, that when Tartarized Antimony or Ipecacu- anha are taken into the stomach, in emetic or diaphoretic doses, they act upon an immaterial property of this viscus, in causing emesis or diaphoresis! Can it be believed, that the diuretics, Copaibce, Cubebs, Turpentine, &c., operate upon the vital properties of the urinary apparatus in producing diuresis, or that Belladonna, Stramonium, Strychnia, Conia, Alcohol, and the vapors of Ether, or Chloroform, expend their force upon the spiritual properties of the brain and nerv- ous system; or that the preparations of Mercury, Iodine, &c., exercise their powerful influence upon the organism, by impressing immaterial, imponderable or vital properties? We think it is more consistent with known facts and sound logic, to suppose that all such agents exert their influence primarily upon the sentient extremities of the nerves, modifying the functions of those parts which they supply, increasing their susceptibility to the influence of foreign agents, and thus establishing inflammation or a new action. It has been remarked by Dr. Paine, as well as by other authors, that Arsenic, Antimony, Iodine, Mercury, &c., given in certain small and repeated doses in disease, are productive of decisive effects, while the same doses in health, would exert no appreciable influence. For this reason, they assert and would have us believe, that the conditions and properties of diseased parts are so modified and altered in all respects, as to be incapable of responding to the action of those medi- cines which operate specifically in health. It is quite certain that most medicinal substances may be taken in very small doses during health, without any apparent effect, on account of the power which the system then possesses of resisting the aggres- sions of slight foreign agents: but if the same substances be taken in large doses, most decided, powerful, and specific results will follow in all states of the system. If taken in still smaller quantities, the effects are yet perceptible, but less strongly marked. These results will be unequal in point of intensity in normal and abnormal states of the organism, according to the amount of disease present; but in all instances, their specific operations will be uniform. Tartarized Antimony and Ipecacuanha, in large doses, both in health and disease, exercise a specific influence upon the stomach, lungs, and skin, as is indicated by vomiting and augmented secretions 120 GENERAL PRINCIPLES OF MEDICAL SCIENCE. from the respiratory organs and skin. In doses of one-sixth or one eighth of a grain, no effect is produced upon the respiratory muscles or stomach, but the influence is yet visible upon the skin. If the quantity be diminished still farther, even to an attenuation according to the rules given by Hahnemann, the impression may not be perceptible, either upon the stomach, lungs, or skin, yet we find them capable of influencing the extreme nerves in a decided manner. It does not follow, because a patient does not vomit, purge, or sweat, that a medicine has no effect. On the contrary, we know that morbific agents give rise to the most virulent diseases without creating the slightest sensation in the system at the period when the noxious impression is made. The direct and sympathetic effects of such agents are, however, severe and dangerous. Experience on the most extensive scale has proved in the most conclusive manner, that minute quantities of medicinal agents may pro- duce salutary influences in the same manner; and the law obtains with regard to specific medicines. The effects in these instances may not indeed be sufficient to induce emesis, catharsis, or other violent effects in any part of the body; yet from the great sensibility of the minute nervous ramifications, they must receive impressions and be modified in their action, when the trunks or larger branches of nerves, would remain unaffected. Who shall decide when the quantity has become too small to produce an effect upon the most sensitive parts of the body? Shall the allopath, because he does not witness vomiting, purg- ing, or sweating; or the homoeopath, who from accurate observation in numerous instances, notes from infinitesimal doses, prompt and decisive curative effects? To illustrate our meaning more fully, we will suppose a certain medi- cine possessing the power, when given in large doses, during health, of affecting a particular tissue. The same substance, administered in very small doses under the same circumstances, has no apparent influence. If now, the tissue for which it has a specific affinity, becomes inflamed, its susceptibility is so acute, that an extremely minute quantity of the specific agent is capable of making potent and salutary impressions. The other parts of the organism which become disordered through the media of the sympathetic nerves, also acquire an exalted sensibility which renders them highly impressible, and capable of being acted upon by infinitesimal quantities of specific medicinal agents. Homoeo- pathic remedies, as Paine has Avell observed of medicines generally, act only through these “ acquired relations,” and their power ceases as soon as these acquired relations have been removed and health re- established. We shall appreciate, then, the importance of selecting a remedy which shall cover, not only the symptoms resulting directly from the INFLUENCE OF REMEDIAL AGENTS ON ORGANS AND TISSUES. 121 tissue primarily affected, but which shall embrace all of the remote sympathetic effects. In other words, we must prescribe for the “totality of the symptoms.” “It will now be apparent from what has been said in the preceding section, how it is that remedial agents will call into salutary reaction sympathies in various parts of the body not affected by disease, but wThose susceptibilities are increased by morbific sympathies reflected from the seat of absolute disease, and upon which parts the remedial agents might otherwise be inoperative. Whatever, too, may be the complexities of disease, the right remedy will be at least compatible with the whole condition.” (Paine’s Institutes of Medicine.) “A particular state of one organ, such as inflammation, or a secreting action in it, often causes the production of a similar state of other parts.” And “the principle of the balance of sympathy teaches us how we must avoid aggravating the morbid condition of one organ by the means which we apply to another.” (Muller’s Physiology.) An adherence in all cases to Hahnemann’s axiom : “similia simili- bus” in our remedial measures, is the only means by which this last objection can be obviated with any certainty of success. It is proper here to remark that there are a few apparent, though not real exceptions to the principles which we have advanced. A most remarkable one is observed in the case of tetanus, wdiere enormous quantities of Opium, both in a crude form and in tincture, may be administered by the stomach or rectum, without producing any marked effect. This fact, however, by no means proves that the susceptibility of the parts for which Opium is a specific, is diminished; but it proves only that absorption is prevented. If Opium is injected into the veins, under these circumstances, it has been found by Magendie, Orfila, and Muller, that it exerts its influence in the same manner and degree as when taken during health. We suppose, therefore, that in tetanus the lacteals and other absorb- ents, are in a state of spasm, and thus mechanically exclude the entrance of all substances from their structure. In this manner, opiates and other drugs are shut out of the circulation, and conse- quently, cannot be brought into contact with those parts of the nervous system upon which they exert their specific force, and where alone they possess the power of producing their legitimate effects. All cases of this description, are simply apparent exceptions to the general rule, and do not in the slightest degree invalidate the general principles which wTe have advanced. The public of Europe and America are fast rendering the same justice to Hahnemann and his doctrines, and the time will ere long arrive, when the united wrnrld will rank him by the side of those great men to whom we have just alluded. It is even now conceded by many 122 GENERAL PRINCIPLES OF MEDICAL SCIENCE. * ininent allopathic writers, that the hypothetical doctrines of homoeo pathy are correct. But when we come to the therapeutical inferences deduced from these opinions, we find a wide and essential difference. The allopath, in summing up his method of treatment, has retained all of the violent and barbarous remedies of antiquity, with very little knowledge of their mode of operation upon the human system, and with as little certainty as to whether they will ameliorate or aggravate the disease. The homoeopathist has pursued a different course. In consideration of the facts that the action of no two medicines upon the economy is the same, that almost every agent exercises a peculiar and specific in- fluence upon certain structures only, and that this specific effect obtains both in health and disease, he institutes a series of accurate experiments during health, in order to arrive at the pure effects of different medi- cinal substances. The illustrious founder of homoeopathy not only tested the operation of medicines upon his own person, but he induced others—men of science and undoubted integrity in different parts of Europe—to make trials of the same substances, without informing them of the results of his own experiments; and when their observations were completed, he instituted comparisons, and found that the effects of the medicines upon the different individuals were almost uniformly the same. Having by extensive experiment ascertained with certainty the pure effects of a number of articles during health, he commenced exhibiting them for the cure of diseases, in accordance with the prin- ciple which he had previously conceived to be philosophical and true; and we need not repeat that the results of these experiments were in the highest degree satisfactory. In the early part of his career, Hahnemann made use of the pure mother-tinctures in ordinary doses, but he observed that the primary effects were too active,—there usually occurring a temporary augmen- tation of symptoms. This induced him to reduce his doses until he came to make use of attenuations and dilutions: and he found that, when the medicines were properly prepared, they still had their speci- fication, and that disease was more speedily removed than when cruder preparations were employed. In the preparation of Dilutions and Attenuations, Hahnemann mixed one drop of some powerful extract with 99 drops of Alcohol by vigorous shaking. This was thz first dilution. One drop of this was again mixed with 99 drops of Alcohol. This was the second, and so of other successive dilutions. In preparing the triturations, he triturated one grain of a metal or mineral with 99 grains of Sugar of Milk, of which one grain was tri- turated with 99 of Sugar of Milk for the second trituration. INFLUENCE OF REMEDIAL AGENTS ON ORGANS AND TISSUES. 123 The third trituration was dissolved and then treated as a fluid sub- stance. He carried this process to the 30th degree. But the principal objection ever raised against the system of homoeo- pathy is the supposed inefficiency of infinitesimal quantities of medicines when administered as curative agents. Nor is this at all surprising, for it has been customary for three thousand years, when disturbance prevails in the human citadel, to storm it with agents of destruction. Blood is made to flow, the delicate membranes of the stomach and in- testines are raked with broadsides of emetics and drastics, the nervous system is shattered by narcotics and stimulants, and the functions of every organ deranged by showers of destructive allopathic missiles with which the enfeebled body is constantly assailed. By these sum- mary means the disturbance is smothered, but the citadel is in decay its resources exhausted, its foundations impaired, and its strength for- ever diminished. Homoeopathy resorts to a different mode of procedure. In her re- medial measures she uses no unnatural violence, nor seriously disturbs the function of any organ: but her remedies are exhibited with a de- finite object; the affected organ or tissue is acted upon with almost mathematical certainty, and that too without creating disease in healthy parts, or in any way complicating the natural affection. But she usually administers her medicaments in infinitesimal, or at least at- tenuated doses, and we now come to the question, whether such minute quantities of matter are capable of producing salutary impressions upon the organism when laboring under disease. No one will deny, that the human body during health is constantly being acted upon and disturbed by influences or agents so subtle that neither the chemist nor physiologist can analyze or even detect them. The simple application of substances to the surface of the body is suf- ficient to produce decided and permanent effects. Turnbull says, that “ so small a portion as the one-hundreth part of a grain of Aconite made into an ointment and rubbed upon the skin, has produced a sen- sation of heat, pricking and numbness, that has continued a whole day.” A leaf of tobacco applied to the wrist or sole of the foot, will excite the action of the respiratory muscles, blood-vessels, glands and skin, causing nausea, vomiting, &c. If the leaves of Hyoscyamus or Belladonna be applied to the eye, an effect will be produced, which will remain for several weeks. It is asserted by Pereira and Sigmond, that a “ dilatation of the pupils may be produced by only approximating the leaves of Hyosyamus or Belladonna to the eyes.” It is also well-known, says Paine, that “violent erysipelatous inflam-, mation over the whole surface of the body is often induced from ap- proaching within a few yards of several species of Rhus.” 124 GENERAL PRINCIPLES OF MEDICAL SCIENCE. The wild buffalo scents the hunter for a distance of more than a mile, and hastens from the vicinity of danger. The carniverous bird recognizes the odoriferous particles arising from a dead carcass miles distant in the air, and with hasty wing pounces upon the prey. The medicinal quality of cod-liver oil (01. Jec. Aselli) consists of Iodine distributed in infinitesimal quantities throughout the oil. Ac- cording to an analysis made by Falker, the Iodine forms only the one- forty-thousandth part of the oil, being about equal to a third or fourth homoeopathic attenuation of Iodine, The value of this naturally at- tenuated medicine in the treatment of scrofula and consumption is at the present time generally conceded. The analysis of Stein, De Jongh and Balard fully confirm that of Falker. The very minutest quantity of the natural poison of certain animals, the virus of hydrophobia, small-pox, kine-pox, syphilis, and gonorrhoea, is sufficient, when placed in contact with an abraded or delicate sur- face, or otherwise introduced into the system, to give rise to all of their corresponding maladies. Other diseases, like scabies, leprosy, &c., may be communicated by the mere touch, or from inhaling the breath of an infected person. Miasmata, animal exhalations, electricity, magnetism, heat, light, and even mental emotions, are all, under certain circumstances, capable of disturbing the organism and causing dangerous maladies, and yet, as Liebig, in his Animal Chemistry, truly observes, “ with all our discoveries, we shall never know what light, electricity, and magnetism are in their essence. We can ascertain, however, the laws which regulate their motion and rest, because these are manifested in phenomena. In like manner the laws of vitality, and of all that disturbs, promotes, or alters it, may cer- tainly be discovered, although we shall never learn what life is.” Let it be ever borne in mind, that most substances, both in the or- ganic and inorganic kingdoms, possess certain active principles which are latent and unappreciahle in the natural state, and are only called forth and developed by some agent or process, which effects a transformation or metamorphosis of the crude material. Heat, electricity, and magnetism, become apparent when certain phy- sical substances operate upon each other in such a manner as to dis- turb or change the original state of cohesion of particles. Caloric is a property common to all material substances. In the natural state of these substances, this active principle is latent, and can not be appreciated by the senses; but if friction be used, this agent is set free, and its power becomes manifest. Electricity also pervades all material bodies, and only becomes sen- sible when the natural state of these bodies is disturbed by friction. It is probable, likewise, that iron and other substances contain mag INFLUENCE OF REMEDIAL AGENTS ON ORGANS AND TISSUES. 125 netism in a latent state, and only require the operation of certain in- fluences, to develop in them the phenomena of magnetism. This is evident from the fact, that u the same magnet may successively mag- netize any number of steel-bars, without losing any portion of its origi- nal virtue ; from which it follows, that the magnet communicates nothing to the bars, but only develops, by its influence, some hidden principle.” (Beale’s Chemistry) These forces are all now known to be only modes of motion. Large quantities of vegetable, animal, or mineral substances, may be taken into the stomach in a crude state, with impunity; but if their elementary particles become separated by decomposition, or otherwise, and then introduced into the system, they give rise to the most baneful results. It is a matter of little consequence, whether this minute sub- division of particles is effected by the action of solar heat and mois- ture, by trituration, or succussion ; the ultimate effects are the same. The elements of the substance are separated, the essence or medicinal part is set free from the crude, material, and non-medicinal portions, and reduced to such a state of attenuation as to become readily ab- sorbed, and yet retain all the specific qualities pertaining to the ori- ginal agent. Indeed, so minute and subtle are the miasms from vegetable and animal decomposition, the exhalations arising from contagious disorders, &c., that no one has yet been able to appreciate their physical or che- mical properties, by the most accurate tests of chemistry or optics. Who, howrever, for this reason will presume to deny or doubt their tre- mendous, although mysterious power upon the human system ? When Ether or Chloroform evaporates, the cohesion between the par- ticles of the liquid is destroyed; its elements float in the air, and are capable of impressing the organism in a much more powerful, and in a totally different manner from any impression which could be pro- duced by these constituents in a less attenuated state ; as, for example, that of the original liquid. If a large quantity of Ether be swallowed, but slight effects will result; but if an imponderable quantity be intro- duced into the blood through the lungs, in the form of vapor, it is im- mediately brought into contact wTith the brain and nervous system, and the most astonishing effects speedily ensue. “ If the -nrh-oth part of a grain of tartrate of Mercury be diffused through the substance of a mere hard sweet-pea, the beautiful germ of a graceful flowering herb which lies folded up in its horny pericarp, shall never come out and be expanded, though you imbed it in the softest mould, and solicit it by every art.”—(Leuchs.) Professor Doppler of the Royal Institute of Prague, in speaking of the modus operandi of infinitesimal particles, writes thus: “From the moment in which the substance of the atoms succumbs to the influence of 126 GENERAL PRINCIPLES OF MEDICAL SCIENCE. their surfaces, and apparently independent of the law of gravitation, they move with the greatest facility in every direction, and, as it were, become alive ; from that moment only, in my opinion, drugs acquire the capa- city of penetrating the organism, and of exciting there a curative effect For if drugs, prepared in this manner, be brought in contact with the invisible extremities of nerves, their hyper-microscopical atoms will enter the organism at the same time with their superficial electricity, and will, if the nerves be in a perfectly natural state, be thrown out of the system without impediment, after having penetrated it in every direction. But, if a body in state of health be accompanied by an ac- tivity of the nervous system perfectly unimpeded and equally free in every direction, we cannot on the other side, but presume, that in a state of imperfect health the power of conduction proper to the ner- vous substance will be materially diminished, partially and in indivi- dual organs, either in consequence of a chemical change, or for some other reasons. But to use rather a material, but nevertheless by no means unfit comparison, as streams deposit the sand and pebbles they carry along, on those spots only where their currents meet with an im- pediment, and their rapidity seems broken by obstructions, so in a similiar manner, in the diseased organism, may the electric currents, however feeble, leave the atoms at the diseased spots, where they, ac- cording to their individual properties, exert a curative or detrimental influence.” If, then, imponderable substances possess powers so unequivocal and potent upon the healthy subject, when the organs are in high state of vigor, and consequently in a good condition to resist the influence of foreign impressions, why may we not infer, with perfect propriety, that medicinal substances, equally imponderable, are capable of impressing the organism during disease, when the affected structures are unusually susceptible to extraneous influences? Homoeopathists suppose that the mode in which their attenuations operate is analogous to that of infection by miasms ; that the inert matter of the substance is destroyed, and the active principle set free ; and that the smallest quantity of this active principle, triturated with sugar of milk, or diffused in water or alcohol, is capable of communicating to the vehicles its properties, and thus to the organism its peculiar action. The essential principles of all vegetable substances constitute but a very small proportion of the original crude article, and the more per- fectly we separate these active from the inactive portions, the more pure and powerful will the remedy become. Like caloric, electricity xnd magnetism, the strength remains latent in their crude state of the substance, and can only be developed by the important agency of heat, friction, or trituration. Peach-blossoms, the bark of mountain-ash, the kernels of peaches, INFLUENCE OF REMEDIAL AGENTS ON ORGANS AND TISSUES. 127 cherries and plums, bitter almonds, &c., contain, in a latent condition the active poison known as Prussic-acid, which may readily be obtained from either of these articles by a chemical process. Ipecacuanha is indebted for its virtues to a principle called emetine. Pelletier found, upon analysis, that the brown Ipecacuanha-bark con- tains only sixteen per cent of impure emetine; and the red bark four- teen per cent. According to Berzelius, the impure emetine possesses only one-third the strength of the pure. We therefore find, that of one-hundred parts of crude Ipecacuanha, only five parts possess the medicinal virtues of the drug. Nor is it all improbable, that farther researches will enable the chemist to free this principle from other impurities, and thus deve- lop a still more potent medicine. Opium contains but a very small per centage of its narcotic principle, Morphia. The crude substance contains in addition to Morphia, at least fourteen other ingredients, all of which are destitute of any particular virtues. Only about eight or nine per cent of Morphia is obtained from Turkey Opium, and this is quite impure and unfit for use, containing Narcotin, Ac. Cinchonia is composed of ten or twelve ingredients, of which, all but Quinia and Cinchona, are inert. Even these last, as usually obtained, are highly adulterated, and do not by any means re- present the active principle of Bark in its purity. The same rule obtains in relation to most other substances. The essential properties are distributed but sparingly throughout ligneous, resinous, and other matters, and it is only by the utmost care and nicety, that we can separate and develop these properties. Indeed, there are many instances where the skill of the chemist is unable, not only to develop artificially certain principles of vegetable and animal substances, but even to analyze them when they become spontaneously disclosed by the action of heat and moisture. Miasmata and other noxious exhalations are examples of this kind. It is a fundamental law of therapeutics, that the active properties of all medicinal substances can only be manifested from their surfaces; and it follo-ws as a consequence, if we would develop the full powers of drugs, that they must be made to occupy as great a surface as possible. If a compact piece of wood be ignited, but a small blaze can be pro- duced; while, if the same wood be cut into small portions, so as to expose a large surface, and then ignited, a large and powerful flame will appear. Only a limited amount of electricity can be drawn from a given sur- face of glass; but if the same glass be made to occupy double the space, an additional amount of the fluid may be set free. If a hole be rapidly made through an ordinary piece of iron, the surface 128 GENERAL PRINCIPLES OF MEDICAL SCIENCE. of each chip so detached will be found to possess magnetic properties and a singular circumstance connected with this, is the fact, that when the boring is accomplished in a perpendicular direction, the chips are more highly magnetized than when it is effected horizontally. Here, again, is an instance Avhere friction has developed properties entirely unappreciable in the natural state. A single grain of matter may be made by trituration to pervade every part of one hundred grains of sugar of milk, and each molecule thus separated, may be still farther subdivided into corpuscles, which in their turn may be diffused intimately through additional quantities of the medium. In this manner only, can we call forth all the latent pro- perties of drugs, and reduce them to that state of attenuation which is compatible with absorption, and which enables them to exert those salutary specific influences which the homoeopathic practitioner so uni- formly observes. Each atom thus minutely separated, retains the power of exercising its specific influence upon the organism. Quantity is of but little consequence, provided, that the substance is properly prepared; for an imponderable quantity in its highest state of development is quite as capable of producing its peculiar effects in certain conditions of the body, as a much larger amount. It is undoubtedly true, that an atom, either morbific or medicinal which possesses an affinity for a particular structure, is capable of com municating to such structure its peculiar action, the influence being propagated from one molecule to another, and each acquiring the properties of the original atom, until the influence is expended. Ex- amples of this kind of action are constantly presented to the physician in the form of continuous sympathy. One inhalation of a noxious miasm, under favorable circumstances, is as capable of causing its specific contagion, as a thousand, or more. One thousandth part of a grain of a natural or morbid virus, is as capable of imparting the peculiar action of the poison to all parts of the organism susceptible to its influence, as a larger quantity. So also, when an atom of a medicine is absorbed into the system and comes in contact with an organ or tissue already diseased, upon which it exercises a specific influence, it communicates to the surrounding atoms its peculiar action until the w'hole tissue is involved, and thus, if the remedy be homoeopathic to the malady, it will supersede the primary affection. La Place and Berthollet have advanced the opinion, that “a mole- cule, being put in motion, can communicate its motion to others, if in contact Avith them.” This law is applicable to both animate and inanimate matter, under certain circumstances. Thus, the smallest point of decayed vegetable INFLUENCE OF REMEDIAL AGENTS ON ORGANS AND TISSUES. 129 or animal matter, if placed in contact with healthy vegetable or animal substances for which it has an affinity, will communicate to the latter its own morbid condition. The smallest point of decay in a tooth, continually propagates its peculiar action to the surrounding parts, until the wrhole tooth is destroyed, or the diseased portion is removed. The slightest spark of fire, put in contact with a combustible material, communicates its action to all parts susceptible of combustion. A minute nucleus being once formed in the mineral kingdom, possesses the power of attracting to itself in a regular and uniform arrangement, all of these particles near it, for wdiich it has an affinity, and the different varieties of minerals communicate to these particles their own peculiar action and arrangement. It is asserted by the supporters of the chemical hypothesis, “that substances in a state of putrefaction, by entering the blood, impart their peculiar action to the constituents of that fluid, and all the sub- stances of the body are induced to undergo a modified putrefaction.” (Paris' Pharmacologia.) Liebig affirms that “ a body, the atoms of which are in a state of transformation, may impart its peculiar condition to compounds with which it may happen to communicate.” These assertions, however, are not sustained by facts. There is no proof that the blood becomes contaminated by the atoms which enter it in a state of transformation; nor is there any proof that such atoms are capable of “imparting their peculiar conditions,” indifferently to other “compounds with which they may happen to communicate.” Every substance in nature, whether morbific or medicinal, possesses its own characteristic and distinct mode of action, and is only able to exercise or communicate this action, m a specific manner to particular structures. Thus, the contagion of scarlatina imparts its peculiar action to the throat and skin. The contagion of scabies acts exclusively upon the skin. The miasms which occasion many kinds of fever, appear to expend their effects upon the nervous system. The virus of gonorrhoea is specific and uniform in its results upon the mucous mem- brane of the urethra. The virus of syphilis, although more general in its operation, affects only a certain class of structures. All of these poisonous matters are incapable of imparting their peculiar influence, unless they are brought into contact with those tissues for which they possess a “ kind of elective affinity.” There is no reason to suppose, that in any instance we have named, the blood itself is contaminated, but it serves merely as the vehicle which conveys the morbid particles to the different parts of the body. What we have advanced in regard to the modus operandi of morbific, is equally true of medicinal agents. We have before shown, VOL. I—9. 130 GENERAL PRINCIPLES OF MEDICAL SCIENCE. that most drugs possess well-defined specific actions, which can only be manifested after having been conveyed by the blood to their destined structures. It will be perceived that the views here advanced, in regard to the mode of operation of morbific and medicinal agents, differ essentially not only from those of the chemical school, but also from those of most writers who have hitherto appeared as advocates of homoeopathy. From quotations made at page 106, it will be observed, that Hahnemann him- self is a firm advocate of the “ vital theory.” In common with many distinguished writers of the old school, he supposes all diseases to con- sist of certain alterations of the “vital properties” of parts, and that medicines cure these diseases by acting upon these (supposed) im- material properties in such a manner as to restore them to a normal state. In advocating these doctrines, Hahnemann has virtually rejected the theory of absorption, the truth of which has been so ably maintained by Muller, Pereira, Blake, and others, and thus has raised opposition to a portion of his beautiful system. It may seem impossible, at a first view, that attenuated drugs can be absorbed into the system, and exert their influence topically on the different structures ; but in support of this opinion we beg leave to submit the following ideas:— Medicines, as we have already remarked, are often detected in those structures on which they have exerted their effects. Mercury, Iodine, Sulphur, Nitrate of Silver, the Salts of Lead, Iron, Bismuth, Copper, &c., have all been found in different tissues of the economy; and even Liebig himself advises us, that many of these substances often form “per- manent compounds with the different tissues.” The same author also remarks, “if by the introduction of a substance certain abnormal con- ditions are rendered normal, it will be impossible to reject the opinion, that this phenomenon depends on a change in the composition of the constituents of the diseased organism, a change in which the elements of the remedy take a sharer The elements of the remedy do most certainly take a share in this change, but only so far as the disordered organ or tissue is concerned. It matters not, whether the specific agent be imponderable in quantity, administered through the lungs, stomach, or skin, or injected into the veins; it seeks that part for which it has an affinity, and there mani- fests its force. I have known persons to become salivated by the use of less than one half of a grain of the first trituration of Corrosive Sublimate given in divided doses. This can be explained in no other way than by sup- posing that the remedy is rendered innoxious to the absorbed vessels by the peculiar mode of preparation; for so small a quantity of the crude article has never, to our knowledge, been known to produce this INFLUENCE OF REMEDIAL AGENTS ON ORGANS AND TISSUES. 131 result. By trituration, the crude particles of the mineral are so minutely separated and diffused through the vehicle, that the delicate absorbents admit them into the circulation with facility, while in an unprepared state the remedy would be recognized as an irritaruand consequently excluded. When salivation is produced by large doses of Calomel or Blue-mass, it is highly probable, that evaporation occurs from the heat of the stomach and intestines, and that this vapor, impregnating the chyle, is absorbed. It has been said by the opponents of absorption,'that the preparations of Mercury cannot be absorbed on account of their in- soluble nature, and therefore that salivation is caused by an im- pression which is made upon the “ vital properties” of the stomach, and that this impression is reflected to the salivary glands through the sym- pathetic nerves. But, if the advocates of this doctrine will reflect, that Mercury evaporates at a common temperature, and that this vapor, when inhaled, exerts all the specific effects of the mineral, they must admit, that when submitted to the higher temperature of the stomach and bowels, this evaporation and absorption will be augmented. “ I be- lieve,” says Pereira, “with Buchan, Orfila, and others, that metallic Mercury in the finely divided state in which it must exist as vapor, is itself poisonous.” An argument which we deem conclusive upon this point is from the fact, that traces of Mercury itself have often been detected in the se- cretions, excretions, and solids of the body: and if any “ vital properties” have reflected the influence, they must have conveyed the solid sub- stance along bodily to the affected glands. &c. In considering the subject of absorption and the topical action of attenuated drugs, it must be remembered, that the absorbing structures are very delicate and sensitive, so that they are enabled to exclude all crude and irritating substances ; and also that the extreme terminations of the nerves in all parts of the body are exquisitely susceptible to the influence of specific foreign agents : and a cause, capable of affecting powerfully these minute filaments, would be entirely without energy and unappreciated, if brought to bear upon the trunk or larger branches of the same nerve. Another fact, illustrative of the truth of absorption and topical action, is, that substances always exercise their specific effects more promptly and potently when introduced directly into the mass of the blood, than when taken by the stomach. “ Medicinal or poisonous agents injected into the blood-vessels exert the same kind of specific influence over the functions of certain organs, as when they are administered in the usual way, but their influence is more potent.” (Pereira.) Liebig also assures us, that “we can by remedial agents exercise an influence on every part of an organ by substances possessing a well-defined chemical action.” 132 GENERAL PRINCIPLES OF MEDICAL SCIENCE. There is a distinct recognition of the principle of the topical or spe- cific action of remedial agents, although the character of this action is supposed to be chemical. Without entering into any discussion iipon this point, or attempting to explain, how morbific or remedial agents produce their peculiar effects, we shall remain satisfied with the po- sitions we have before laid dowTn, and simply refer our readers to the numerous instances within their own knowledge, of the topical action of substances, both ponderable and imponderable, with the addition of a few examples of the latter, which can be understood and appreciated by all. 1. Odors. When odoriferous particles are brought into contact -with a certain nasal structure, (the Schneiderian membrane,) the minute and sensitive nerves of the part, take cognizance of the stimulus, a decided impression is made upon the whole membrane, and an odor, agreeable or otherwise, according to the nature of the exciting cause, is the result. In this instance, physical, but imponderable particles operate upon the nasal tissue by absolute contact, and impart that peculiar action which enables us to appreciate odors. 2. Light. According to Sir Isaac Newton, light is a physical, but imponderable compound, and can only manifest its power -when its atoms are in contact -with the organ of sight. These particles of light are the natural stimulus of the eye,—material, imponderable, specific. When this compound is separated into different primary rays, each particular ray, when brought into contact with the eye, exercises a special and distinct influence, giving rise to the perfect appreciation ot the different colors of the prism. Here again we are presented with an example of the specific influences of imponderable atoms upon a certain part of the system. On the dynamic theory the illustration is more forcible. 3. Heat. Newton also maintained, that caloric is “ a distinct material substance, the particles of which repel one another, and are attracted by all their substances.” When caloric is given off by a heated body, its atoms impart to all other atoms with -which it comes in contact, its own peculiar action, and the sensation of heat, with its attendant phenomena, expansion, &c., is the consequence. Here we are furnished with a still more striking in- stance of the power of an imponderable substance in altering and modi- fying the character and properties of all substances upon which it exercises its action. This active principle, present in all bodies, hidden and except when set free by friction, percussion, mix- ture, electricity, or combustion, possesses properties when thus libe- rated, surpassing in power and influence every other substance in nature; yet it is more subtle and imponderable than the most attenuated medi- cines of homoeopathy. 4. Electricity, galvanism, magnetism, and the various gases, are INFLUENCE OF REMEDIAL AGENTS ON ORGANS AND TISSUES. 133 all material substances and manifest their influence physically by contact with the body. It must not be supposed, that light, heat, electricity, magnetism, &c., are merely imaginary properties of matter,—because they can not be weighed, handled and made subservient to all of those con- ditions which govern more crude substances. Nor must it be sup- posed of drugs, that they possess no qualities except those which are apparent in the crude state, and can be fully appreciated by their nauseousness of taste, offensiveness of smell, or power of raking the stomach and intestines. Modern science has demonstrated, that by f riction, percussion, mix- ture, &c., some of the most powerful principles known may be liberated from substances which in a crude state are entirely harmless. It has shown, that the more perfectly we can disencumber these principles from their inactive envelops, the more potent they become. It has been shown that the mass of ligneous, resinous, starchy, fatty extractive, and coloring matters, which surround and enclose the active portions of vegetable substances, instead of possessing medicinal properties, serve only to nauseate and oppress the stomach and bowels, and thus complicate any existing malady. Pereira, and other authors opposed to our system, have endeavored to cover it with ridicule by entering into a computation respecting the weight and strength of the different attenuations. They have displayed before us tabular views showing the strength of each attenuation, and then assured us, without the trouble of testing the question practically, that such exceedingly small doses of medicines can produce no effect upon the system, but “that the supposed homoeopathic cures are refer- able to a natural and spontaneous cure, aided, in many cases, by a strict attention to diet and regimen.”—Mater. Med. & Therapeutics.) This is the principal argument urged against the therapeutical doc- trines of Hahnemann. We beg leave, however, to request those gentlemen who judge of the potency of substances by their weight and dimensions, to enter into a still further calculation, and inform us which possesses the great- est weight, the medicinal particles pertaining to a drop of a thirtieth attenuation of a homoeopathic remedy, or the charge of electricity, which lays prostrate and senseless the strongest man,—or the quantity of sulphuretted hydrogen, or carbonic acid-gas, requisite to cause im- mediate death when inhaled ? Which can be most readily detected and appreciated by analysis, the atoms of a high attenuation of Hahne- mann, or the deleterious miasms which arise from vegetable or animal decomposition? Which present the greatest difficulties in examination and descrip- tion, the physical structure of the particles of a homoeopathic medica- 134 GENERAL PRINCIPLES OF MEI’ICAL SCIENCE. merit, or that of small-pox virus ? Will the respectable Hippocratic, who can not recognize power in any material substance, unless it can be weighed or handled, enter into a computation, and inform us how much a poisonous dose of the vapor of Hydrocyanic-acid, Mercury or Lead, weighs? Let it be remembered, that not one atom of matter in the whole uni verse can be annihilated j transformations may be effected—the cohesion of particles may be changed—atoms in their ultimate state of chemical combination may bz physically divided into molecules, and again sub- divided into lesser atoms to such an extent as to baffle detection from the most perfect tests of chemistry or optics—new powers may be deve- loped in these atoms, the exact operation of which we may not at pre- sent be able to understand, but in no instance can we destroy one single particle of matter. We may effect an entire metamorphosis of almost any solid substance, and diffuse its elements in such a manner as to occupy and effect a very large amount of space. The elements of a few grains of gun-powder may be made with the aid of the imponder- able influence of caloric, to change their form, and impregnate every por- tion of the atmosphere of a large room. In like manner, a single grain of a vegetable or mineral substance may be transformed, and its atoms diffused throughout large quantities of inert materials, in such a manner as to impregnate them in every part with medicinal properties, but in no instance can a single atom be annihilated. Until we arrive at more accurate knowledge in relation to the laws which govern the chemical and physical action of the minute atoms of substances than we at present possess, let us not deny that they may be endowed with properties and powders (although their modus medendi is a mystery to us), capable of exercising an important influence upon the human organism. But it may not be possible in the present state of human science to follow the operations of nature through each particular step. It may be that we are not yet in possession all the materials necessary for the erection of a perfect theory of cure • and that none of the hypo- theses yet advanced are entirely true. On this point we may accept the conclusion reached by a faithful laborer in the field of medical reforms. Dr. Joslin says : “ Many physiological and pathological problems are of such a cha- racter as to present to those wrho may now attempt their solution, elements of uncertainty similar to those encountered by previous medi- cal theorists; so that considered in relation to some of those collateral or auxiliary topics, Reformed Medicine is not destined to be exempt from slow development. Here lie the same rocks on which have been wrecked so many navigators of other times, compelled by their position simultaneously to encounter invisible undercurrents, and unforeseen INFLUENCE OF REMEDIAL AGENTS ON ORGANS AND TISSUES. 135 shifting winds. The investigator is compelled to grapple with a problem of numerous and uncertain elements.” But in our efforts to master the complex problems that rise to meet us as we progress, “ our position is different from that of the physiological schools. With them, theories of the functions of the human organism are the foundation of therapeutics. They are working at one unfinished monument; we a another. Their alterations are in a considerable degree, fundamental and cause dilapidations in the superstructure, and necessitate its fre- quent demolition and reconstruction. We build on an immovable foundation, and every extensive alteration involves progression. “ In proportion to our faith in this, will cceteris paribus, be our happiness and activity; for one of the most agreeable and effectual incitements to labor, is the certainty of success.” In regard to the preparation of medicines, there are several points of difference worthy of particular notice, between the old and new schools. 1. Allopathy employs her drugs in a crude and consequently in- active form ; while homoeopathy makes use only of their pure essential principles, unencumbered by foreign matters. 2. Allopathy employs so great an amount of artificial heat in her pharmaceutical operations, that a large proportion of the active pro- perties of her drugs is expended in evaporation; while homoeopathy makes use only of expression, trituration, and succussion, and thus not only retains all of their virtues inherent in the drug, but actually develops powers which would have remained latent under other cir- cumstances. 3. On account of the peculiar mode of preparation, the remedies of allopathy are offensive to the taste, they nauseate the stomach ; and, by in their indigestible and irritating qualities, serve directly to induce gastric and intestinal derangement, and other serious medicinal symp- toms. The medicines of homoeopathy are liable to none of these objections. 4. For the reasons above enumerated, many of the remedies of the old school are excluded by the sensitive absorbents, on account of their irritating qualities, and are thrown off with the faecal matters as foreign substances; having failed in their passage through the intestinal canal of producing any other effect than an irritation of the gastro-intestinal membrane. The attenuated remedies of homoeopathy being innocuous to the lacteals and absorbents, are readily admitted into the circulation, and conveyed to those parts upon which they exert a specific action, thus impressing directly the organs or tissues actually diseased. “No substances,” says Martyn Paine, “ but such as exist in a fluid or very attenuated state, are taken up by the lacteals and absorbents.” So, also, in the therapeutical application of remedies, wre claim, a 136 GENERAL PRINCIPLES OF MEDICAL 3CIENCE. far as accurate scientific principles and sound philosophy are concerned, that homoeopathy is vastly superior to allopathy. We shall briefly re- iterate some of the more prominent points of difference in the practice of the two schools. The system of homoeopathy is founded upon rational and scientific principles, inasmuch as its remedies are exhibited with a definite object, and the results can in most cases be predicted with mathematical certainty. The practice of allopathy must always be indirect, uncertain, and empirical. The violence of the remedies employed, necessarily induces medicinal and sympathetic affections, which, mingling with the symp- toms of the natural disease, render it impossible to distinguish between the two classes of symptoms, or to judge whether the malady, or the medicine, or both combined, are killing the patient. The fact that so few allopathic practitioners coincide precisely in regard to the treat- ment of very many diseases, proves conclusively that their system is one of guessing, rather than one founded on scientific knowledge and ascertained facts. Homoeopathic remedies being specific and certain in their effects, operate only upon those parts, which are actually diseased. Without inflaming healthy structures, debilitating the 'system, or disturbing the function of any organ, they induce, when judiciously exhibited, anew or alterative action in the part affected, of just sufficient severity to banish the natural malady, while the new or medicinal action subsides speedily and spontaneously. According to the doctrines of homoeopathy, no two diseases or kinds of inflammation can exist in the same structure at the same time j for whenever two exciting causes act upon the same part, the one possess- ing the most powerful action, must necessarily banish and supersede the weaker. Therefore, in accordance with the rules of our system, remedial impressions are always made directly upon the organ or tissue affected, and a new kind of action set up, which abolishes the disease and usurps temporarily its place. According to the strict tenets of the old school, remedies should be exhibited in such a manner as to impress structures wThich are healthy and remote from the organ or tissue diseased, in order that revulsive, derivative, or counter-irritating effects may be produced, and thus serve to attract the fluids from the natural affection to the artificial one. This plan of treatment originated as wxe have seen, from the sup- position that no two maladies of consequence could exist in different parts of the same organism at the same time. As this idea is at present universally conceded to be erroneous, we assert that a mode of practice deduced from such false data, must of necessity be unscientific and empirical. INFLUENCE OF REMEDIAL AGENTS ON OKGANS AND TISSUES. 137 By operating on healthy structures, the allopath accomplishes little or nothing towards restoring the impaired capillaries of the affected their original condition of strength and resistance, and conse- quently his system must be entirely inadequate to effect cures. We are, for this reason, forced to the conclusion that the “Modern Celsus,” Dr. Forbes, is correct when he asserts that “in a large proportion of the cases treated by allopathic physicians, the disease is cured by nature, and not by them.” It is a fundamental law of medicine, that no inflammation can be created in any part of the body, without giving rise to secondary sym- pathetic affections in oth,er and distant parts. It is evident, therefore, that the greater the number of structures affected with inflammation, whether natural or artificial, the greater will be the number of sym- pathetic symptoms, and consequently the more serious and complicated the malady. Thus we perceive the force of Dr. Forbes’ remark, “that in not a small proportion of the cases treated by the physicians of the old school, the disease is cured by nature, in spite of them: in other words, their interference opposing instead of assisting the cure.” We have before shown that organs and tissues become morbidly susceptible to the impressions of specific remedial agents during in- flammation ’ therefore it is, that extremely minute quantities of specific medicaments are capable of exercising powerful influences during disease, -which, under circumstances of health, would be productive of no effects whatever. This is a truth of vast importance in the admi- nistration of medicines, and should be thoroughly appreciated by the practitioner who regards the welfare of his patients. Let him remember that these acquired susceptibilities are so great, that even the natural stimuli, food, gastric juice, bile, light, &c., can not be tolerated; and from this fact, take warning lest he inflicts injury and counteracts the efforts of nature by too active medicines. But as we have so frequently observed, it is not so much our prin- ciple of cure, at which the shafts of the old school are directed, as to the doctrine of small doses. It is not because the adherents of allo- pathy cannot make themselves acquainted with the powers of attenu- ated drugs, but it is because their inveterate prejudices will not allow them to investigate the facts which are involved. They prefer to die of vomiting, purging, and sweating, as their predecessors have done for two-thousand years, rather than to be cured quietly under a new system. These individuals are not satisfied unless they feel and see the poor body writhe and suffer for the sin of being sick. What care they for any interior or invisible action of a medicine, when they can be cut, racked, and tortured, by the lancet, emetics, cathartics, blisters and mixas, and that too, secundum artem! To be sure, they were not aware of any visible effects to hen the morbid agent operated upon 138 GENERAL PRINCIPLES OF MEDICAL SCIENCE. their systems to produce the disease, but the curative part is in their own hands, and they are determined to exercise their privilege of a full and continual appreciation of the whole modus operandi of the remedial process. This part, nature has no power to cheat them of, but Hippo crates now reigns, and they are resolved to exercise their anoien reserved rights, and bleed, vomit, purge, sweat, and blister, ad libitum But why have our opponents dwelt so much upon our doses! Does not every homoeopathist aim and intend to give a sufficient quantity of the medicine at a time to effect a speedy cure; and is not this quantity determined by experience of simple facts ? We have different strengths or attenuations of each medicine, from the strongest tincture up to the most minute attenuation, and every homoeopathist selects that strength or attenuation of the drug which most speedily and safely cures his patient. The great point with him is, to select such a medicine as shall be homoeopathic to the symptoms of the disease, and then to ad- minister just enough of it to effect his object in the most safe and speedy manner. He finds by experience—by a mass of facts,—that the tinctures and alkaloids, although often capable of subduing disease, are less prompt, less efficient and less safe than finer preparations of the drug. This easily demonstrated truth, was not the result of theory or hypothesis, but originated with Hahnemann, as we have already seen, through necessity, on discovering that the tinctures which were first employed by him, in accordance with his principle, often produced too violent impressions upon the affected structures. What cared Hahnemann—what care his disciples—whether they use one or twenty drops of a tincture, or one grain of a twentieth attenuation ? Were twenty drops of a tincture, or twenty grains of a crude substance more efficient in curing sickness than one drop or one grain of an attenuation, is there any man who supposes that Hahnemann or his followers would not have administered them in this form, in preference to any other? The chief glory of the founder of homoeopathy does not consist in the discovery of the efficacy of small doses, but in the demonstration aud practical introduction of the great doctrine of curing maladies by impressing diseased tissues with medicines which operate specifically upon these tissues themselves, rather than on distant parts. It matters not therefore, in regard to the homoeopathic law of cure, whether we use this or that strength, provided the remedy is homoeo- pathic to the disease, and exactly the requisite impression is produced upon the affected parts. The man who cures a Belladonna headache with ten drops of the tincture (if he be successful) adheres to similia sirnilibus as much as he who cures with the thirtieth attenuation of the medicine. The only question to be decided is, which strength cures most safely and quickly; and if facts prove, as all homoeopaths believe, that a preparation (apparently) weaker than the tincture is by INFLUENCE OF REMEDIAL AGENTS ON ORGANS AND TISSUES. 189 far the most safe and efficient, then it is our duty to give these pre- parations the pi-eference. It is found, for example, when repeated doses of tincture of Belladonna are given in acute inflammation of the brain, that the primary symptoms from the drug manifest themselves too violently—that it causes dangerous and protracted medicinal aggrava- tion, and a tardy reaction of the organism; while a dilution of the remedy impresses mildly the diseased structure, causing scarcely per- ceptible primary symptoms, and is speedily followed by its secondary or curative effects. We shall conclude this section with a few observations by a distinguished chemist (allopathic) respecting the divisibility of matter, and some of the phenomena witnessed when a high degree of attenu- ation has been arrived at. These observations may at least show to those whose minds are not already permanently made up, that, not only morbific and medicinal power may exist in infinitesimal atoms of matter, but even life itself. “It has been proved, that gold may be divided into particles of at least TrroVoTo of a square inch, and yet possess the color and all £ther characteristics of the largest mass. If a grain of copper be dissolved in Nitric-acid, and then in water of Ammonia, it will give a decided violet color to 892 cubic inches of water. Even supposing that each portion of the liquor of the size of a grain of sand, and of which there are a million in a cubic inch, contains only one particle of copper, the grain must have divided itself into 392 million parts. A single drop of a strong solution of indigo, wherein at least 500,000 distinctly visible portions can be shown, colors 1000 cubic inches of water; and as this mass of water contains certainly 500,000 times the bulk of the drop of the indigo solution, the particles of indigo must be smaller than -2-toXuVuTooT), the twenty-five hundred millionth of a cubic inch. A rather more distinct experiment is the following: if we dissolve a fragment of silver, of 0.01 of a cubic line in size, in Nitric-acid, it will render distinctly milky 500 cubic inches of a clear solution of common salt. Hence the magnitude of each particle of silver cannot exceed, but must rather fall short of a billionth of a cubic line. To render the idea of this degree of division more distinct than the mere mention of so imper- fectly conceivable a number as a billion could affect, it may be added, that a man, to reckon with a watch, counting day and night, a single billion of seconds would require 31,675 years.” According to Doppler, a cubic inch of brimstone, broken into one million equal pieces, a sand grain each in size, is magnified in sensible surface from six square inches to more than six square feet. It is calculated in this way, that, if each trituration of the homoeopathist diminishes his drug a hundred times, (an exceedingly moderate allowance) the 140 GENERAL PRINCIPLES OF MEDICAL SCIENCE. sensible surface of a single inch of sulphur, or any other drug, shall he two square miles at the third trituration. “In the organized kingdoms of nature, even this excessive tenuity of matter is far surpassed. An Irish girl has spun linen yarn, of which a pound was 1432 English miles in length, and of which, consequently, 17 lb 13 ounces would have girt the globe; a distinctly visible portion of such thread could not have weighed more than tsTToVriTtnru gr-> cotton has been spun so fine that a pound of the thread was 203,000 yards in length, and wool 168,000 yards. And yet these, so far from being ulti- mate particles of matter, must have contained more than one vegetable or animal fibre: that fibre being of itself of complex organization and built up of an indefinitely great number of more simple forms of matter. The microscope has, however revealed to us still greater wonders as to the degree of minuteness which even complex bodies are capable of possessing. Each new improvement in our instruments displays to us new races of animals, too minute to be observed before, and of which it would require the heaping together of millions upon millions to b$ visible to the naked eye. And yet these animals live and feed, and have their organs for locomotion and prehension, their appetites to gratify, their dangers to avoid. They possess circulating systems often highly complex, and blood with globules bearing to them by analogy, the same proportion in size, that our blood globules do to us: and yet these globules, themselves organized, possessed of definite structure, lead us merely to a point where all power of distinct conception ceases; where we discover that nothing is great or small but by comparison ; and that presented by nature on the one hand with magnitudes infinitely great, and on the other hand with as inconceivable minuteness, it only remains to bow down before the omnipotence of Nature’s Lord, and own our inability to understand Him. {Kane's Chemistry, by Draper, p. 19.) It is not by supplying deficient chemical materials to the blood that remedies are to cure disease. It is true, that in various diseases the blood is deficient in phosphates, carbonates, sulphates, lactates, acetates, &c., of soda, lime, or other ingredients of normal tissues; these salts are not, however, furnished to the blood by food, as phosphates and carbonates, &c., but are formed within the organism, and from material whence the chemist must often despair of extracting them. Whatever the absorbents receive, undergoes profound and radical transformations, provided it be not in such excess as to embarrass the functional activity of the organs which dispose of it. A controlling vital force then forms the different compounds as they are needed, instead of delegating cer- tain organs to select them ready made. Mr. Gundlach, of Cassel, shows experimentally that wax is forme 1 from honey in the body of the bee, although the honey contained ap parently no trace of wax. Liebig remarks the absence of fat in tb \ INFLUENCE OF REMEDIAL. AGENTS ON ORGANS AND TISSUES. 141 flesh of the carnivora, which of all animals eat most fat; while the cow extracts butter from herbs and roots, suet from hay and fodder, &c. The sugar of the maple is found not in the roots, but in the woody sub- stance of its trunk, increasing only up to a certain height. Sugar, starch, gum and humic acid, so nearly allied in their composition to plants, are not food for them. Sugar can only be absorbed and appro- priated in the tree like any other foreign matter. All the animal viruses and venoms, hydrophobine, and the serpent-poisons are rendered inert by the operation of digestion in the stomach, while the most innocent articles of food received into the stomach of the viper furnish its body with all the elements of its structure and secretions, and are trans- formed into the deadly venom in the glands which elaborate that fluid. Lehmann and others have proved that sugar, found in the blood, is not assimilated as sugar from those aliments which most abound in sugar, but from the fibrine and albumen, the proportions of which are reduced in the blood of the hepatic vein, as compared with that of the portal vein. The vital force executes disintegration and reconstruction upon every compound presented to it. Though potash and other salts of alkaline base, Copaiba, Turpentine and Garlic may be detected after absorption in the blood, sweat, chyle, gall or splenic veins, they are speedily excreted with the urine. The patient under treatment has received in general the same kind of food that he took in health, but he fails in assimilative power to ex- tract from the food and appropriate for the uses of the organism the elements essential to his support. Tuberculosis is not the result of a deficiency of phosphates in the food, but of loss of the assimilative power to extract them from it. The object of the scientific physician is not to furnish the system with some infinitesimal quantity of an ingredient which is deficient in the blood. If iron be deficient in the blood and that agent be found a remedy, it becomes such not by furnishing the wanting ingredient, for the quantity we prescribe is not in any degree sufficient for that, but by enabling the organism to appropriate that which is presented to it in the food. The disease does not arise from deficiency of iron in the aliment, but “ the power of digesting, assimilating and forming the food into blood is defective ; and it is this power which is to be restored by medicine. The physician who is ignorant of this, and in treating such a case, regards himself as a mere caterer for supplying materials, will naturally conclude that he must administer ferruginous medijcine, and that the medicine must be given at least in quantities appreciable by chemical tests. “Neither of these conclusions has the slightest foundation in reason. The substance which suitably regulates the vital force in this case, will not necessarily or even generally be iron, but some medicine indicated 142 GENERAL PRINCIPLES OF MEDICAL SCIENCE. by the generality of the symptoms present. Again, the immediate ob* ject not being chemical but vital, it is not necessary nor desirable to employ a dose appreciable to chemical tests, but to the vital test, which is inconceivably more delicate ; the living body can be strongly and durably effected by a dilution, which if concentrated a billion fold would not produce a visible change in any lifeless re-agent. (Dr. Joslin.*) The question is asked, how is it possible for a perceptible influence to be exerted by a minute dose of an attenuated medicine “ when the same substance, as salt or iron, already exists in the blood and in sufficient quantities without it.” This question will only be asked by persons who “ deny that special increase of power called potentization which the homoeopathic medicine receives by minute divisions in the different stages of its preparation, and which gives it an efficiency vastly superior to that of the same quantity in the ordinary state.” To those who admit nothing and deny everything, it may not be easy to present satisfactory answers to all questions prompted by mere curiosity ; and it may not be profitable for us or them to spend much time in abstract reasonings which weak minds do not easily comprehend. The only question in this case is one of fact for an impartial jury to inquire into. A fact well known to many ob- servers is thus stated by Dr. Joslin: The quantity of Natrum-muriati- cum, common table-salt, “taken by almost every man, varies by many grains at his different meals. If he receives a few grains more at one meal than at the preceding one, he has no Natrum-muriaticuin symptoms as the consequence; and common-sense would teach a physician that if he should administer a few grains of the crude substance, he could produce no effect by it The intentional increment must be as inoperative as the accidental. But experience teaches that the potentized form of this medicine in a quantity inconceivably small makes a decided im- pression both on the healthy man and the patient. We are compelled to conclude that it has a power of affecting the system not perceptible in what is chemically the same substance in its ordinary state, or in that state in which it exists in the blood, where it is crude as compared with the form in which it is given by homoeopathists. A thousand physicians daily witness the special power of potencies of other medi. cines, and are thus able to confirm by analogy the preceding conclusion.” ATTENUATIONS OF DRUGS AND REPETITIONS OF DOSES. In selecting our attenuations for the cure of disease, the following circumstances are to be taken into consideration: 1. the age, sex, temperament, constitution, and habits of life: 2. the condition of the disordered textures; 3. the character of the drug to be employed. * American Horn Review, Yol. II., p. 38. ATTENUATIONS OF DRUGS AND REPETITIONS OF DOSES. 143 a. Age.—Infants and children of tender years, whose organisms have not become blunted by exposure to the ordinary stimuli of life, by im- proper food and drinks, and by abuse of cathartics and opiates, are in the most eminent degree impressible and require the highest attenu- ations. It is at this period that the circulation is most active, the nervous system most delicate, and the tissues most sensitive to the in- fluence of external agencies. At the middle period of life, when the body has arrived at maturity and all of the organs have acquired their full strength and vigor, the resisting power against both medicinal and morbific agencies is at its maximum. The action of the circulatory vessels is now moderate and stable, the nerves are strong, the structures have become accustomed to all kinds of stimuli, and the mind, which exercises so powerful an influence over the body, acts calmly and judiciously. At this period our lower attenuations will often serve us more efficiently than the higher, especially in acute diseases. During the decline of life, many circumstances which have a ten- dency to modify the operation of medicines, are to be considered. In- dividuals who have passed their lives in intemperance, who have been afflicted with frequent attacks of disease, and whose systems are loaded with the cumulative poisons of drugs, usually acquire a remarkable obtuseness and inactivity of the whole organism, so that the very low- est attenuations are requisite to effect suitable impressions. On the other hand, many old people, upon the verge of the second childhood, become sensitive, irritable, and so intensely impressible, that the higher preparations respond promptly and effectively. b. Sex.—Females are more easily acted upon by medicines than males, for several reasons. Perhaps the most prominent one consists in their superior delicacy of organization; their circulation is more active, their nervous systems more irritable, and their mental powers more acute and quick, although less strong, logical and independent than those of men. J. J. Rousseau asserts that a woman will leap to a conclusion which would require a man hours of severe thought to ar- rive at. It is this susceptibility and delicacy of organization which renders the female more impressible than the male sex and which should always have no inconsiderable weight in the selection of attenuations. c. Temperament.—Temperament also has an important influence in the operation of medicines. As most morbific and remedial agents produce their effects upon the sentient extremities of the nerves, it follows that a highly susceptible condition of the nervous system is most favorable to the prompt operation of these causes. We therefore infer, that the higher attenuations are better adapted to the nervous than to either of the other temperaments. Next to the nervous temperament, in point of susceptibility, may ' e 144 GENERAL PRINCIPLES OF MEDICAL SCIENCE. ranked the sanguine. Individuals of this temperament are charac- terized by great activity and energy, and by prominent development and vigor of the vascular system. Temperaments which are the least susceptible to remedial impres- sions, are the bilious and the lymphatic. The former is characterized by large muscular developments, tendency to biliary derangements, frequent turns of melancholy, and great powers of endurance. The latter is distinguished by a predominant activity of the glandular sys- tem, by a flabby and relaxed condition of the muscles, and by a feeble and rather obtuse state of the nervous system. These temperaments sometimes require the lowest attenuations, especially in chronic dis- eases. Two or more of these temperaments often unite in the same person, when we have what is termed a mixed temperament. This variety may be considered, upon the whole, the most favorable to health and longe- vity, since no quality predominates, and the functions of the organism are more equalized. d. Constitution.—Attenuations must also be selected with a due regard to the constitutional peculiarities of each particular case. We know of several persons who cannot take a blue pill, or a pill in which calomel is a constituent, without being violently salivated. There are others in whom Opium produces furious and protracted delirium ai d catharsis as primary effects; others cannot carry Ipecacuanha about their persons, or inhale the smallest quantity of it, without attacks of asthma; others cannot approach the rhus-plant without being poisoned; others cannot use shell-fish and certain other sorts of food, without being afflicted with urticaria; the smell of hay causes asthma in some, and the delicate fragrance of the rose, syncope in others. On the other hand, there are some organisms which can scarcely be impressed with even large and continued doses of medicines. Constitutions which have been impaired by abuse of stimulants, drugs, tobacco, and licentious- ness, and in which there is an abasement of the nervous and physical power, demand low attenuations. In a word, it will be found on rigid examination, that each individual possesses some peculiar trait which it will be necessary to take into consideration, when we decide respecting the strength of a remedy. e. Habits of Life.—We have read of persons who were “music mad” but we have often seen those who were “medicine mad” The world is full of this class of monomaniacs, who “pass away their time in descanting on their own diseases,” and in filling their bodies with all sorts of injurious and nauseous drugs. After pursuing this course a long time, the system, by habit, tolerates enormous quantities of the poisons swallowed, and the structures lose in a measure their susceptibility to medicinal impressions. It is for this reason that the homoeopathist ex- ATTENUATIONS OF DRUGS AND REPETITIONS OF DOSES. 145 periences so much difficulty in the management of cases of dyspepsia, hypochondria, and constipation, which have been induced by long-con- tinued abuse of cathartics; also in the affections of confirmed Opium- eaters, habitual drunkards, and gourmands. Individuals of these lasses, require low attenuations. In the same category may be ranked hose operatives who make a breathe-vapor of Mercury, the salts of Lead, itrong acids, and other poisonous substances which evaporate at he ordinary temperature. Robust persons, who pass much time in active exercise in the open tir, will require stronger doses than those of delicate organization and )f‘ studious, sedentary habits. 2. The condition of the disordered textures.—Those parts of the system which are most amply supplied with nerves, are, ail other things being equal, most susceptible to the operation of medicines. Thus the eye is more readily impressed than the arm; the lungs, stomach and intestines, than the limbs, joints, &c. Much also depends upon whether the specific employed, is positive and decided in its operation. But there is another circumstance of vast moment to be taken into consideration in the choice of our attenuations, and to which we have elsewhere called particular attention. We refer to the augmented susceptibility to medicinal impressions which inflamed structures acquire. We have shown that the condition of inflamed tissues becomes entirely changed, and that their acquired susceptibilities become so morbidly increased that even their natural stimuli can not be tolerated, but when allowed to operate, become additional and powerful sources of disease. The natural and healthy stimuli of the eye, the ear, the lungs, the stomach, the bladder, &c., are grateful during the normal state of these organs ; but let inflammation occur, and the smallest pencil of light becomes intensely painful to the eye, as noises to the ear, air to the lungs, food and drinks to the stomach, and urine to the bladder. Nor is this augmented susceptibility confined to the operation of the natural stimuli, but it applies with still greater force to the action of specific medicines, up to the termination of inflammatory action, when the sensitive extremities of the nerves succumb from intensity of excitement, and a condition bordering on paralysis or gangrene obtains. It is sometimes difficult to decide when this morbid erethism has arrived at its maximum, and the atonic state commences ; but the gradual sub- sidence of pain, appearances of effusion or ulceration, and diminished sensibility of the affected part, will afford us the best indications upon this point. This fundamental law of homoeopathy, not only serves to explain in the-clearest possible manner the astonishing effects of infini- testinal doses, but it teaches an important practical fact, at present unappreciated, but incontrovertible, and which stands at the foundation V0T» I.— 1 O' 146 GENERAL PRINCIPLES OF MEDICAL SCIENCE. of our therapeutical applications, viz., to ascend in our scale of attenudr dons in proportion to the violence of the inflammation, until we arrive at that point where the nerves of the diseased part have at- tained their maximum of erethism, after which we must again de- scend the scale in the same ratio. This same law applies Avith equal force to all irritations of the ner- rous system, even Avhen entirely unattended with the usual phenomena of inflammation, redness, SAvelling, heat, and pain. We have often seen this nervous erethism so strongly pronounced—and where there were no signs of vascular excitement—that a single grain of Ipecacuanha, or the twentieth part of a grain of tartarized Antimony, would produce copious vomiting and purging; or a drop of the first dilution of Nux- vomica, induce involuntary contractions of the muscles, especially of those parts which are usually irritable ; or a single grain of Jalap, Rheum, Calomel, or even a mental emotion, immediately cause diar- rhoea ; or a cup of tea or coffee taken in the evening, prevent sleep for a Avliole night; or the inhalation of a feAV imponderable particles of Ipecacuanha, give rise to both its primary and secondary specific effects upon the pulmonary organs. There may be a feAV apparent exceptions to this rule, as in the example already referred to respecting the inefficiency of large quan- tities of Opium and Laudanum in tetanus / but these exceptions are susceptible of ready explanation. In this disease there exists a pecu- liar preternatural excitement of the nerves which preside over the voluntary motions, and the contractility of the tissues, which induces a spasmodic exclusion of those textures of the digestive canal which, in the normal state, permit the absorption of opiates. This is evident from the fact, that if Laudanum be injected into the veins during tetanus, the usual effects are manifested. In this disease, therefore, the drug is not adsorbed, and of course can not exercise its specific effects upon the economy. It is evident, then, that in the selection of attenuations for chronic diseases, the precise condition of the nerves of the affected parts must always be taken into consideration, since some chronic maladies are characterized by a highly exalted ner\rous susceptibility, and call for the use of high attenuations; Avhile in other cases, this susceptibility or impressibility remains at a low grade, and consequently will only respond to Ioav attenuations. Dr. Lobethal, in alluding to this subject, makes use of the following anguage:—“God be praised, the times are passed when we adhered without examination to the prescriptions of Hahnemann, and Avhen Ave administered the thirtieth dilution in every case, without any regard either to the species of the medicine, or the individuality of the patient. The idea of the greatness or littleness is but relative; we cannot say ATTENUATIONS OF DRUGS AND REPETITIONS OF DOSES. 147 in a general manner, that some drops of the mother tincture of a certain medicine will be a strong dose; nor yet perhaps, that the twenty-fourth Dr thirtieth dynamization of every medicine shall be regarded as a feeble dose. The dose of each medicine should be strong enough to provoke the necessary reaction of the organism, and, provided we are careful not to administer a too heavy one, but agreeable to take, and without danger, we should always give a sufficient '.ne. “ I am decidedly convinced, that in order to apply the homoeopathic treatment with success, the physician should take cognizance of the whole scale at his disposal, from the actual dose of the old school up to the highest dilutions of which any medicine is susceptible. “We may establish it as a principle, that the appropriateness of large or small doses is in inverse proportion to the richness in nerves of the individual organism, and the species of diseased organ; that is to say, the more the sentient sphere of the organism, in a given case, shows itself predominant, the more attenuated the dose of the indicated specific medicine should be, and that the more the individual organism, or in a local affection the diseased organ, is poor in nerves, the more the doses should be large.” {Revue Critique et Retrospective de la Matiere Medicate Specif que. Yol. III., 1841.) Dr. G. H. Gross of Germany, also observes, that “homoeopathy, as now accepted, has determined the point, that the physician must exercise his judgment as to the dose, varying it from the highest DILUTION down to ONE OE MOKE DKOPS OF THE UNDILUTED TINCTUEE, as individual cases may demand.” * Dr. E. F. Ruckert, of Germany, also writes as follows: “I am satis- fied that the system (homoeopathy) is still progressive, and has by no means attained perfection. In respect to doses, most generally, I make use of the first dilutions, and never exceed the twelfth, giving them in increased volume and repeating them frequently. I have been more successful in this course of treatment than formerly in the use of the smaller doses.” Similar views have recently been promulgated upon this subject by G. Schmid, Trinks, Griesselich, Watzke, Madden, Bigel, Drysdale, Russell, and indeed by a majority of our school, both in Europe and America. We have not unfrequently been able to cure diseases with a high attenuation, after having failed with the first and second dilutions of the same remedy: but it has been no very uncommon occurrence with us to effect cures with the first attenuation after having been un- successful with the higher preparations. No definite rules, therefore, * Dr. Gross wrote this in 1840 ; but during several years preceding his death, he was a most decided advocate of the highest dilutions. 148 GENERAL PRINCIPLES OF MEDICAL SCIENCE. can be given which will apply in all cases, hut every circumstance con- nected with each particular case must be duly investigated, and the physician then exercise his own best judgment. The appropriateness of a particular remedy for a given set of symp- toms constitutes one problem, and the choice of the proper attenuation another, both of which are to be separately determined, according to the direction of Hahnemann,* by “pure experiments, careful observation, and correct experience.” For practical purposes the rule generally given is, “the more susceptible the organism, the higher the potency, and the finer the doses.” The theory upon which the action of high attenuations is to be explained is not yet settled byhomoeopathists. It has been proposed to apply for this purpose the law of nature mathe- matically demonstrated by Maupertuis, called the law of the least quantity of action, thus expressed by its discoverer: “The quantity of action necessary to effect any change in nature is the least possible.” “According to this general principle, says one of our own writers,! “the decisive moment is always a minimum, an infinitesimal. Apply this to our therapeutics, and it will be perceived that the least possible dose is the highest potency, and necessarily sufficient to turn the scale, that is to effect the cure—always provided the remedy be homoeo- pathically correct. “This law of the least action appears to be an essential and neces- sary complement of the law of homceopathicity, (similia similibus) and co-ordinate with it.” Experience teaches that the strictly homoeopathic remedy, selected according to the law similia similibus curantur, will produce aggra- vations when given in large doses. Dr. Verweg of the Hague opposes large doses: 1. as unnecessary, as the power of a remedy lies not merely only in its quantity; 2. because large doses obstruct the digestion and blood crasis, offices which ought to remain untouched in a sick state, in order to carry it to a happy crisis ; 8. large doses produce so many secondary effects, that the chief effect will appear modified or more or less obscured. 4. Large doses increase the effect to such a degree that exhaustion ensues after the too powerful irritation, stopping either the beginning amelioration or under less favorable circumstances causing death. 5. Large doses produce as many symptoms as the disease it- self, yea, the newly-appearing symptoms of the remedy are often more severe than the symptoms of the disease which we want to cure. 6. Large doses leave after-effects of long duration. 7. Large doses, according to the laws of polarity, have often a contrary effect. It is a common opinion that the lower potencies agree with acute * Organon, p. 278. t Dr. Fincke Amer. Horn. Rev., Apr, 1840 p. 336 ATTENUATIONS OF DRUGS AND REPETITIONS OF DOSES. 149 and the higher ones with chronic diseases, the effect of the lower ones being quicker; hut coarser and more evanescent, whereas, the higher and highest potencies have a slower effect, but more penetrating and longer enduring. Such general rules are only partially correct. Diseases which have a chronic character throughout their course, as cholera, croup, &c., are generally though not always treated by low dilu- tions. The precursory fever of pneumonia is generally broken by low dilutions, whilst the higher are employed to remove the exudations which result from the inflammation. Exanthematous diseases and typhus are treated with high potencies till they localize themselves; hut we return to the lower when new complications arise. In chronic diseases, appearing acute in paroxysms, as whooping cough, migraine, or intermittents, the high dilutions are considered by Mayer most effectual. High dilutions are considered best in chronic catarrhs of mucous membranes, leucorrhoea, nervous and mental diseases, and all blood dyscrasias, new formations, as warts. The difference between the powers of medium dilutions and those much higher, is not always perceptible. Many use only a few out of the great range afforded us, as 1, 2, 3, 6, 12, 24, 30, 60, 200, &c. Trinks divides remedies into 1. Those working on the organism with great energy and intensity, yet fleeting in the duration of their action, even when given in large doses; as, Aeon., Cham., Camph., Moschus, Igna., Ipec., Hyoscy., Coffea, Stram., Samb., Opium. 2. Those produ- cing effects less strong, but more intense, deeply penetrating the organism and their effects lasting for a long time, such as the mineral remedies • Arsen., Cuprum, Merc., Sulph., Graph., Aur., Argen., the mineral acids and some vegetable remedies. Medicinal Interference.—It is considered a practical impossibility to exclude all active medicinal and opposing influences from the pre- sence of our patients, and it is asked, how can wre expect infinitesimal doses to produce their proper effects when they must come in contact with so many antidoting substances ? “ The Camphor in a drawing- room cabinet,—the fumes of a smoking-room,—the oil of a mineral lamp, which in spite of washing perfumes the fingers,” are supposed to have power to counteract the remedies. In answer, it can at least be said, that homoeopathic doses are certainly effectual in curing disease, in spite of antidotes and external influences. The theory may not be satisfactory, but the fact is certain. The explanation is attempted by the Monthly Horn wop. Review : “ The curative power of a medicinal substance, homoeopathically selected, is necessarily higher than the mere antidotal force of an interfering body; and for the following reason: The medicine owes its curative force to the receptivity of the diseased organism to which it happens to be homoeopathic; no twro drugs have an equal pathogenesis throughout, and therefore the antidote 150 GENERAL PRINCIPLES OF MEDICAL SCIENCE. under no circumstances can exercise a power over the disease equal tc the true homoeopathic remedy. The medicine is aided in its operation by the vital force of a diseased and highly receptive organism, while the antidote either acts merely upon the inert medicinal substance to which it is antidotal, or on organs to whose state it has no relation. “That the force of a remedy may be influenced to some extent by its antidotes is no doubt true ; but we believe that a homoeopathically- chosen medicine will, in all cases, and even in the presence of crude drugs, exert a certain curative influence upon a diseased, sensitive and highly receptive organism. The question still remains: What becomes of the impurities which unavoidably exist in the attenuating fluid; and why do not these im- purities neutralize the effects of the minute quantity of the medicine employed in the treatment of disease ? This question has been well answered by Dr. Joslin, in an essay communicated to the American Institute of Homoeopathy, 1858.# He shows, that every time a dis- solved medicine is diluted a hundred-fold, it has its minute parts, called molecules, made smaller and more active, i. e. potentized. On the other hand, “ when a dissolved substance, made a little active by a little di- vision, is brought in contact with the same substance in a still less di- vided and less active state, it unites with the latter and thus becomes like it, comparatively crude and inert,—it loses its special power;” that is, it becomes de-potentized. “ I find that this union by cohesion and consequently this depotentization always takes place when one portion of the substance is only a hundreth part more diluted than the other. Thus, a substance that happens to adulterate the alcohol used for po- tentizing a medicine, is continually combining with and practically nul- lifying itself, and the high potency of the medicine remains practically pure. In this case, the little parts, molecules of the impurity, never differ much in size and never differ so much in the degree and nature of their activity as to prevent their re-union. “ This statement in regard to the conditions of re-union is not a mere hypothesis. It is not only a necessary inference from the fact of po- tentization, but is in accordance with observed facts in crystallization. I have witnessed the crystallization of Camphor, as exhibited by the solar microscope, and observed phenomena which have a bearing on this subject.” Though no microscope has power to exhibit to the eye the smallest crystals first actually formed, it was observed that “ those first visible were in a series of groups, the larger crystals not growing by the addition of invisible ones, but of those smaller ones already formed of others still smaller. The first visible molecules unite with others not too dissimilar -in magnitude, frequently after rotating like * Proceedings of the Fifteenth Annual Meeting. ATTENUATIONS OF DRUGS AND REPETITIONS OF DOSES. 151 little magnets; but they do not unite in the first instance with those whose difference of magnitude is very great.” * If then it be asked: Why does not the iron or culinary salt that exists in the blood, “ and which is identical in name with a medicine administered, unite with the latter, which would thus become depoten- tized and inert ? ” To this question we answer, that whether we are able to explain the philosophy of the phenomenon or not, th % fact is abundantly established in the experience of every man who is accustomed to give our remedies in the medium and higher dilutions, that these remedies are active, though administered dissolved in water, which also contains the same substance in name, though in a form more crude. The fact is thus explained: “ That the union of the two, and the consequent depotentization of the medicine does not occur, I attribute to the discrepancy between their degrees of attenuation. The substance in the natural water and the blood, which can be detected by chemical tests, must be crude, com- pared with the same in our medium and higher potencies, which can not be thus detected. The crystalline affinities of these two kinds of molecules differ so widely, that they may be regarded as on different planes of activity: those in the natural fluid comparatively gross and inert, those in the potency rendered inconceivably minute and active by regular and consecutive attenuations. This activity, so obvious to the physician by the use of the vital test, has not yet attracted the atten- tion of the natural philosopher or chemist, because their tests are not sufficiently delicate.” Adjuyantia.—They are generally permitted : 1. When the special nature of the disease calls for other than medical aid, as surgical cases, the removal of pathological products, toxical cases. 2. WTien we are not permitted by the friends to rely upon the simple homoeopathic re- medies, but know that if we abandon the case, it will go into dangerous hands. 3. Where the proper remedies are not at hand, and the cir- cumstances compel us to do something. The occasions that can justify bloodletting even in the minds of old-school men are not very few. Leeches are of use in but few cases and we have better means of managing them. Purgatives are homoeopathic agents in diarrhoea and dysenteries; in the removal of irritating substances from the bowels they can sometimes be employed. Derivatives, though not often proper or necessary, may in good hands be directed under the homoeopathic law to perform good service, as we shall show in treating of the different forms of disease in which they may be useful. Hahnemann sanctioned their use in proper cases * Am. Horn. Review, Yol. II, p. 40. 41. 152 GENERAL PRINCIPLES OF MEDICAL SCIENCE. (See Chronic Diseases, Vol. I., 238.) Poultices may properly be used to soften abscesses; and cold and warm water can be applied with good effects in many cases. Electricity and its allied powers are recom- mended by Hahnemann. (Chronic Diseases, I., *288.) Mild forms of it are the electric bath, the electric wind, and friction through flannel. Zoomagnetism was also employed by him, as acting according to the law of polarity. The water of mineral springs consists only of well- known medicines in dilution. They would be much more successful than they are if they contained still smaller quantities of the drugs to which their virtues are attributed. Selection of the Proper Remedy.—The rule given by Hahne- mann is to choose from the many remedies before us that which presents the principal symptoms found in the individual case of disease. Though it is often difficult to find a remedy which has the whole, of them, it should always be fairly sought for. The remedy that will certainly cure, will be one that exhibits “not only tbe symptoms of the disease as present, but also the symptoms of the patient’s constitutional state.” “ Many symptoms,” says Jahr, “ which our school considers as mani- festations of the general disease, are considered as independent diseases by beginners, simply because they find particular names for individual diseases in the books.” “The proper selection of a remedy in chronic, and generally in acute diseases depends upon the following three points: 1 The remedy must correspond to the pathognomonic symp- toms of the case;—2. To the accidental symptoms which do not seem to be a part of the essential phenomena of the disease;—3. To all other diseases and morbid phenomena which we may be able to dis- cover in the patient. If the patient be afflicted with pneumonia, Ave would not only record the essential symptoms of pneumonia, but also the symptoms of any other affection which might happen to exist with the inflammation of the lungs ; and, moreover, the general morbid phe- nomena of the organism, no matter AA-hether the books speak of them as symptoms, or as independent diseases.” The formula of Hahnemann, that like cures like, has suggested the question, asked by Ilering, “ What is the like which cures t ” and also his ansAver, that “it is that Avhieh is characteristic.” The meaning of both question and answer has been elucidated with sufficient clearness by Dr. Wells of Brooklyn: In the treatment of dysentery, ‘What is the like which cures,’ and how are we to find it? In other words, Avhat are the characteristics, i. e., of the drug and the disease ? It is obvious at the first glance, that there are tAvo classes of these. One, the generic, which determines the case you have to treat as belonging to the genus dysentery, belongs alike to all the members of the genus, and without which no case is dysentery. The other, the specific, that which ATTENUATIONS OF DRUGS AND REPETITIONS OF DOSES. 153 listinguishes individual members of the genus from all other mem O O bers. “ It is worthy of remark, that there is in the pathogenesis of all drugs a class of symptoms, which in their relation to the law of cure are very analogous to the generic symptoms of disease. The allusion is to that class of symptoms which rather indicate that the organism revolts against drug-assault, than point out the particular active agent in the assault. For the same reason that generic symptoms of disease can rarely be availed of as guides to the selection of a curative, these are of comparatively little value to the prescriber. The vomiting pro- duced by one irritant poison is so like that of every other, that from this alone it cannot be told what irritant it is. So of the diarrhoea, nausea, thirst, loss of appetite, headache, &c. These of themselves can never be guides to a prescription, though the elements associated with them may be. It is not then to the generic symptoms of either drug or disease that we are to direct our attention chiefly, in our search for the “ like which cures.” “Where then are we to look for this ? Evidently in the list of those symptoms which individualize both the disease and the drug. That which distinguishes the individual case of the disease to be treated, from other members of its class, is to find its resemblance among those effects of the drug which distinguish it from other drugs. This is what we mean when we talk of “characteristics” as the great reliance of intelligent practice, and assert that with these the law of cure has chiefly to do. It is precisely in this relationship that the law exists. When we say that ‘ like cures like,’ this is the like we mean.” * The student of homoeopathy is always perplexed by finding a dozen remedies enumerated as proper for a certain disease. He sometimes learns to discriminate between them, and finds that every diseased state is capable of being covered by a single remedy and none other. Ho- moeopathy is the science of specifics, not in the sense that old-school men call Mercury a specific for syphilis, Iodine for scrofula, but in the sense that there are no diseases, but only diseased states,■ and every specific remedy, which will alone cover that state and necessarily cure that state. Every prescription based on nosological genera and species is wrong; true therapeutics lies only in the individualism of the Ma- teria Medica. 3. The Character of the Medicine to he employed.—Certain sub- stances which are very feeble or even inert in their natural crude state appear to acquire new and potent qualities on trituration. Whether these new properties are communicated to the minutely-divided par- ticles by a chemical combination with the oxygen of the air, for which * Diarrhoea and Dysentery, P. P. Wells, M.D., New-York, 1862, p 27; ibid, p. 29. 154 GENERAL PRINCIPLES OF MEDICAL SCIENCE. several, like Carbon, Graphites, Sulphur, Lime, &c., possess a very strong affinity, or whether they arise from the simple subdivision of the atoms of the drug, we are unable to determine. But these are the me- dicines which have been found especially serviceable when employed in high attenuations. On the other hand, there is a class of medicines so volatile in their nature, that trituration and exposure to the air and moisture deprive them of their active principles. Amongst these articles may be ranked Camphor, Ammonia, Bromine, Argenti-nitr., the Ethers, the Volatile Salts, &c. Medicines of this kind should always be administered in the lower attenuations. We must also be governed somewhat by the positive or negative character of the specific employed. Some medicines are very marked and prompt in their specific operation, like tartarized Antimony, Phos- phorus, Ipecacuanha, Belladonna, Aconite, Hyoscyamus, Stramonium, Opium, &c., and may ordinarily be used at rather higher attenuations than those whose primary effects are less prompt and strongly pro- nounced. The advantages which we obtain from a minute subdivision of crude substances are as follows: 1. We develop every part of the active principle pertaining to the substance by breaking up all natural organization or arrangement be- tween its molecules, and thus exposing a large amount of active surface which would otherwise have remained latent. 2. By distributing these molecules intimately throughout an inert vehicle, (sugar or water,) they are far more readily absorbed by the delicate lacteals and absorbents, than coarse and irritating particles of matter. 3. When these minute atoms have been conveyed by the blood to those parts with which they have an affinity, they penetrate the smallest vessels, impress the minutest sentient nerves, and become productive of results entirely unattainable by drugs in a crude form. 4. During the act of subdivision, it is not improbable that the atoms of drugs sometimes become oxydized, and thus acquire new and in- creased powers. In regard to the repetition of doses, we are to be guided by the acute or chronic nature of the malady, the urgency and danger of the symptoms, and the effects produced by the medicine. In violent and dangerous acute diseases, like cholera, asphyxia, convulsions, phrenitis, pleuritis, gastritis, &c., the remedies should be repeated as often as every fifteen, twenty or thirty minutes—until an aggravation of the symptoms, (that is, some primary effect of the drug,) appears, or a perceptible amelioration of the symptoms is apparent when the medicine should be omitted, in the first case, until the seco7b ATTENUATIONS OF DRUGS AND REPETITIONS OF DOSES. 155 dary or curative symptoms have appeared, and then expended them- selves ; and in the latter, so long as amendment continues. If the case demands it, recourse may again he had to the same medicine ; or if new symptoms have made their appearance, another appropriate remedy may be selected. In less urgent cases of acute disease, it will he sufficient to repeat the remedy every four, six, or eight hours, until primary symptoms (aggravation) occur, or amelioration of the symptoms evincesthe secon- dary or curative effects, when we may rest tranquil until the amend- ment ceases, and the medicine has expended its curative effect. In chronic maladies the remedy may be repeated once in twelve or twenty-four until an impression is perceptible, either in the form of primary drug-symptoms, or of amelioration of the morbid condition. When this result obtains, we may with great propriety wait until the full effects of the medicine have subsided, before we repeat the dose In these cases it is far better to make use of doses sufficiently strong, and repeat them sufficiently often to induce decided primary medicinal symptoms—even if we are obliged now and then to give antidotes— rather than to remain for weeks in doubt as to whether a suitable im- pression has been produced by a single dose. It is very rare that mo- derate drug-symptoms are productive of unpleasant consequences in chronic diseases, while the reaction thus induced in the diseased tissue usually has the effect to bring about a much more speedy cure. Indeed we believe it may be set down as a general rule, that the sooner we can produce a moderate, but decided medicinal action in a structure suffer- ing from chronic inflammation, the sooner will a curative reaction fol- low, and health result. “It would, therefore, appear that experience has confirmed the opinion of Hahnemann, that a certain amount of aggravation is essential to the therapeutic process; in the vast majority of cases this does not make itself known in any perceptible degree, but it does occur in a cer- tain, though small amount of cases, sufficient to confirm its existence as an essential phenomenon. The cases in which it occurs with infini- tesimal doses are probably only those of excessive or even idiosyncratic susceptibility, and even with these it is a phenomenon of no danger, and only slight inconvenience.” Hence we may conclude, that a nor- mal dose of homoeopathic medicine, sufficiently small to avoid the liability to aggravation in a certain amount of cases, and yet sufficient to cure best and quickest in the majority of cases, is a mere chimera, and ought not to be sought for; but in seeking for doses the best for the majority of cases we must lay our account for meeting with a certain number of aggravations, but practically these latter are of no importa nce. Likewise in the case of collateral symptoms, it is affirmed by Hahne- mann. that “ we cannot arrange our doses so as to escape the liability 156 GENERAL PRINCIPLES OF MEDICAL SCIENCE. to them in a small and practically unimportant degree.”—(Dr. Drys- dale: British Jour, of Jlomceop. No. XIII. p. 22.) In all cases of urgent acute disease, in which we can find no single remedy which corresponds to the symptoms, it is necessary to select a second remedy which shall cover the remaining symptoms, and ad- minister it in alternation with the first. Pneumonia is often accom- panied by cerebral inflammation; typhus fever, with serious disorder of the intestinal canal, the lungs, the brain, and nervous system; inter- mittent fever, with enlargement of the liver, jaundice, cough, &c., and other maladies with affections in other parts of the body, which are not strictly connected with the original complaint. In examples of this kind, the alternation of remedies is both proper and necessary ; at the same time it must be remembered, that it is far more desirable that a single medicine should be chosen which covers all the symptoms of the disease. The same rule holds good with respect to giving medicines in suc- cession. Whenever the first remedy fails in producing the required impression, or whenever important new symptoms arise to which the original drug does not correspond, we may resort to another which corresponds to the totality of the symptoms. A large proportion of homoeopathic physicians, both of Europe and America, now advocate a frequent repetition of doses in acute diseases, and in many instances alternations of the remedies. Some of those who have expressed themselves decidedly upon this point, are, Drs. Gross, Schmid, Rau, Fleischmann, Reiss, Ruckert, Lobethal, Hart- mann, Russell, Hull, Neidhard, Gray, Currie, Trinks, Griesselich, Madden, Dudgeon, Quin, &c. The erroneous ideas which were formerly entertained respecting the alternate employment of remedies, are at present nearly abandoned. So long as the opinion prevailed that our medicines could only operate in a kind of spiritual manner upon certain mysterious appendages of the organism termed “ vital properties? it was deemed unsafe to administer two remedies in alternation, for fear of creating confusion among these dynamic influences; but since the laws of medicinal action have become better understood, there is no longer hesitation in alternating medicines whenever symptoms appear to require it. Some remedies continue their action for a very short time, others show a duration of action of thirty-five to forty days. Strong doses act more energetically* on both the healthy and diseased organism, and their action continues longer than that of weaker and smaller doses. In acute diseases all remedies act more energetically, but their effect is more evanescent. They are therefore treated by doses, if not larger, at least given at shorter intervals. In chronic diseases the process of disease is less conspicuously visible, making often great remissions and REPETITION OF REMEDIES. 157 .ntermissions; remedies act more slowly, with less apparent energy, but their effects last much longer. In robust irritable persons, rich in vital power, the curative effect appears and vanishes quickly, and the time of action is short; in tor- pid, phlegmatic constitutions, remedies act more slowly, but with more lasting effect. In childhood the primary effect of remedies is evanes- cent on account of the rapid process of life, and passes quickly to its curative effect. In old age there is a longer primary action, and a relatively short secondary action. The following rules are given by Koch: 1. The more perfectly similar the curative potency the less neces- sary is a repetition of it; but repetitions in very small doses may be safe, and sometimes necessary to complete the cure. 2. The less per- fect the similarity of the curative potency, the more necessary is the repetition. 8. The more intense the diseased action is, the more fre- quently the dose may be repeated. 4. The more acute the disease the more frequent the repetition. 5. The more completely similar the curative potency to the symptoms of the disease, the more injurious the repetition of large doses. When a proper remedy has been given and amelioration results, the rule is not to repeat so long as'amelioration continues. Repetition is proper : 1. When the amendment has ceased. 2. When the receptivity to the effect has died out, and larger doses are necessary to have effect. 3. When the disease is acute the repetitions may be frequent and thus time is saved, the secondary products of acute inflammation are prevented. 4. In putrid fevers and other adynamic diseases where collapse is threatened. 5. When disease manifests itself in paroxysms, exacerbations, or spasms. In diarrhoea, colic or vomiting, repeat as often as the attack recurs. On the practice of alternating remedies, Jahr says: It is very common for physicians to prescribe two medicines in alter- nation, and this at longer or shorter intervals, according to the nature or intensity of the disease. This, though in some cases proper is, per- haps, not generally so. “The custom,” says Jahr, “ has had its origin in a one-sided view of the nature of disease. If the symptoms of a disease were viewed as they ought to he, as the phenomenal manifesta- tion of an internal state, and if their pathological connection and depen- dence upon each other were properly known, it would most probably never be necessary to prescribe two remedies at the same time. It is only wdien symptoms are viewnd superficially, without reference to their internal unity, that it seems as though they were disconnected and re- quired more than one remedy at a time. Though it is proper always to cure the disease by a single remedy, it is certain that all prescribes are not capable of always selecting 158 GENERAL PRINCIPLES OF MEDICAL SCIENCE. the true remedy; such must be permitted to cover the given case by alternating the two articles which, in their view, come nearest to it. If either happen to be the true specific, it will cure in spite of many adverse influences. Another reason for alternating, given by Jahr is that different groups of symptoms are often connected through patho- logical relations. We take an example from some affection of the pneumogastric nerve. This is a nerve of sensation and also of motion. “It is a nerve of sensation simply because it supplies the lining membrane of the respi- ratory and digestive passages, and it becomes a nerve of motion when it supplies the muscles and muscular coats of the same canals. The pneumogastric nerve supplies branches, on the one hand, to the larynx, the lungs, and the heart ; and on the other to the pharynx, the oeso- phagus, the stomach, and the solar plexus. These different parts could not fulfil their organic functions without the assistance or vitality which they derive from that nerve. The branches of the nerve are essen- tially the same ; the functional differences reside in the structural organization of the parts over which the branches are distributed. These anatomical facts lead to important practical results in the treatment of disease. Let us suppose for example, a diseased condi- tion of the pneumo-gastric nerve, an acute irritation of this nerve, a neurosis, in which the various branches of the pneumo-gastric nerve are principally involved ; such a pathological state would necessarily be characterized by the most diversified symptoms, symptoms which would apparently be disconnected, and yet would constitute one iden- tical group ; for the irritation would be the same in every branch of the nerve, but the symptoms characterizing the irritation would differ ac- cording as the structural organization of the part affected would differ from that of another part. We might have dryness, soreness, and heat in the larynx, with constant tickling, disposition to cough and hawk; stricture across the chest; aching pain or weight in the region of the heart, or palpitation of the heart; loss of appetite, and coated tongue, nausea, oppression of the stomach, sensitiveness and fulness or bloated- ness in the region and pit of the stomach, or a hard aching pain in the pit of the stomach ; or sensation as of a cold stone in the pit of the stomach ; soreness of the bowels, looseness or constipation.” &c. In this apparently disconnected group of symptoms we perceive that each one constitutes one of a unitary group connected together by the various branches of the pneumo-gastric nerve, and if we can find a remedy capable of acting on the pneumo-gastric nerve specifically so as to produce only a portion of these symptoms, we shall by employing it be able to strike at once at the seat of the disease before us. By this single remedy we shall more effectually subdue it than we could hope to do by searching the Materia Medica for a remedy that shall present OF CHANGING THE REMEDY. 159 all the phenomenal symptoms of the case; and, failing to find them under a single remedy, employing two or three remedies which may between them cover the whole list of symptoms. OF CHANGING THE REMEDY. It is very common to change the remedies too often. If a medicine has produced a decided improvement in the symptoms, that is, if the symptoms remain the same, hut are less intense, or if only some of them have disappeared and others remain with the same degree of intensity, the original medicine which caused this modification of the primitive group should be continued by all means, for this reason: that such a modification of the original disease is not an evolution of a new group of symptoms, but simply a reduction of the former symptoms to a lesser degree of intensity. Suppose a case of inflammatory rheumatism, with a full and hound- ing pulse, high fever, pains in the joints and bones, swelling and inflam- mation of certain parts, or any of the other manifold symptoms which characterize this disease. We prescribe Aconite. After the first three or four doses the fever is abated, perhaps is entirely subdued ; the pains in the joints and bones are less, and the inflammation is consider- ably reduced. This change of the symptoms does not constitute a new group requiring a different remedy; on the'contrary, the same remedy is still indicated, and if continued, will speedily remove the existing symptoms. Sometimes we find that by repeating one remedy often, even in in- creasing doses, the organism becomes habituated to it, and ceases to be affected by it. If then another remedy be substituted as an in- termediate or intercurrent remedy, in small dose, we may return again to that originally selected. Griesselich advises: 1. Change when the remedy has lost its effect, or has failed to produce that which we had expected. 2. Alternation, when two remedies are seen to be appro- priate for different portions of the organism; then, one is given at one hour and the other at another. 3. Successory remedies'. When one remedy is only partially effectual, another may be selected which has a close relation to the first; as a case not satisfactory cured by Cal- carea may be finished by Sulphur. Belladonna is often necessary after Aconite. Antidotes.—An antidote in the homoeopathic sense, is not a sub- stance which is capable of neutralizing the curative action of a drug, or of opposing it, as cerebro-spinal sedatives ; as Coffee antidotes Opium, or Camphor, Cocculus-indicus;—but which is suited to the re- moval of symptoms arising from medicinal aggravation by the remedy previously administered. Thus a well selected-medicine may be con 160 GENERAL PRINCIPLES OF MEDICAL SCIENCE. tinued too long, and its own symptoms may be added to those of the natural disease; or an inappropriate remedy may have been selected, producing drug-symptoms, in addition to those previously existing; then the homoeopathic antidote is the medicine which best covers the totality of the symptoms belonging both to the natural and acquired disease. Its administration, therefore, interrupts the action of the firs medicipe, because it has, itself, become the most homoeopathic of the two. In this sense Hahnemann employed homoeopathic antidotes: “ If, however, among the symptoms of the remedy selected, there be none that accurately resemble the distinctive, (characteristic,) peculiar, un- common symptoms of the case of the disease, and if the remedy cor- respond to the disease only in general, vaguely described, indefinite states, (nausea, debility, headache, &c.,) and if there be among the known medicines none more homoeopathically appropriate, in that case, the physician cannot promise himself any immediate favorable result from the employment of this unhomoeopathic medicine. (§ CLXV.) “Such a case however is very rare, owing to the increased number of medicines known, now-a-days, with regard to their pure effects, and the bad effects resulting from it, when it does occur, are diminished whenever a subsequent medicine of more accurate resemblance can be selected. (§ CLXYI.) “Thus, if there occur, during the use of this imperfectly homoeo pathic remedy, first employed, accessory symptoms of some moment then, in the case of acute diseases, we do not allow this first dose to act completely out, nor leave the patient to the full duration of the effects of the remedy, but we investigate afresh the morbid state, in its present altered condition, and add the remainder of the original symptoms to those newly developed, in tracing a new picture of the disease. {Organon of Medicine, § CLXVII.) In his elaborate work on Syphilis, published in 1789, Hahnemann dwells at length on the necessity of antidoting the effects of Mercury, when it has been used in excess for the cure of syphilis, and recom- mends for this purpose the administration of Hepar-sulphuris, which he believed was the chemical antidote of Mercury, and of many other me- tallic poisons. It is curious that in later years he recommends the same Ilepar-sulphuris as one of the dynamic antidotes for the inconveniences produced by small doses of Mercury unhomoeopathically administered. In 1798 he wrote an essay on Antidotes to some powerful vegetable substances, in which he attempts a classification of antidotes. He says the hurtful substance may be antidoted in one of four different ways: A. Removed, 1. By evacuation, as vomiting purging, or by excising a poisonous bite; 2. by enveloping, as giving suet where pieces of glass have been swallowed. OF CHANGING Till? REMEDY. 161 B. It may be altered, 1. chemically, as Hepar-sulphuris for Corrosive Sublimate; 2. dynamically (i. e. their potential influence on the living fibre removed,) as Coffee for Opium. Dr. Dudgeon, in his “Lectures on Homoeopathy,” says, the occasions for the, employment of homoeopathic antidotes are very rare. “The rationale of the administration of Camphor, Sweet Spirits of Nitre Wine, &e. in the case of over-action of a drug seems to be that thereby a stronger but transient and different effect is produced upon the nerves, whereby the feebler impression of the medicine previously given is effaced, and the new action, being evanescent, the nervous system is speedily restored to its former equilibrium—or a dynamic neutralization is effected.” Hahnemann advised the employment of one remedy at a time, not from the fear that one will neutrate the other, but because the result cannot be predicted with the desirable degree of certainty. Thus, the vapor of Kreosotic-oil, in a mineral oil lamp,—or Camphor, floating in the atmosphere, or Musk, may have a homoeopathic relation to the dis- ease under treatment, and the practitioner may ascribe his results to the wrong agent. On this subject Hahnemann says: “In no case is it requisite to administer more than one single and simjple medicinal substance at one time.” (§ CCLXXII.) “It is not conceivable, how the slightest dubiety could exist as to whether it was more consistent with nature, and more rational, to prescribe a single, well-known medicine at one time, in a disease, or a mixture of several differently-acting drugs.” (§ 273.) “As the true physician finds in simple medicines administered simply and uncombined, all that he can possibly desire (artificial morbific agents which are able by homoeopathic power completely to overpower, extinguish, and permanently cure natural diseases,) he will, mindful of the wise maxim, that it is wrong to attempt to effect anything with compound means that may be effected by simple means, never think of giving any but a single simple medicinal substance.” (§ 274.) We know that the effects of every medicine on the animal organism are either partially or totally annulled by another medicine of which the positive effects are more or less similar to the first one in its symptoms, its local and general tendencies and character. “ The remedies per- fectly similar in their positive effects annul one another; whereas, those whose positive effects cover only solitary organs or tendencies, annihilate only those symptoms in which the correspondence of similarity holds out.” It is allowable to use antidotes: 1. When aggravations have been caused by over-doses of a proper remedy, as well as by one not correctly selected. 2. To relieve symptoms produced on the prover of a remedy. 3. For the cure of medicinal dyscrasias. 4. Related or successory remedies act as antidotes to each other; and the greater is Vol. L—11. 162 GENEKAL PKINCIPLES OF MEDICAL SCIENCE. their similarity in their positive symptoms the more decided are their effects in antidoting each other. When a medicine has been abused to the extent of developing a drug-disease, it may be, after long enough time, removed by a remedy which has some relations of similarity. When we are able to detect too few symptoms in a case to cdipe to a positive choice of a true remedy, we prescribe that which covers such as are visible; and then, when other symptoms appear as called out by the remedy tried, make a new selection, endeavoring to find one that is the similimum of the whole disease. Mode of Administering Remedies.—The practice of Hahnemann in later years of his life is given by Dr. Croserio, (N. Archiv.l.2.p.31,) who says he often witnessed its success. “Hahnemann always made use of the well-knowrn small globules, which were generally impregnated with the 30th dilution, both for acute and chronic diseases. Of these globules he directed one, or at most two, to be dissolved in a caraffe, containing from three to fifteen table- spoonfuls of water, and a half or a whole tablespoonful of French brandy. One tablespoonful only of this solution was put in a tumbler- ful of water, and this last the patient took by teaspoonfuls; on the first day one teaspoonful, on the second two, on the third three, and so on, a spoonful more daily until he felt some effect. He then diminished the dose, or discontinued the medicine entirely. In other cases he caused a spoonful of the first tumbler to be poured into a second tumbler of water, in others, from this last into a third, and so on to a sixth tumbler, and directed a teaspoonful to be taken from the last tumbler only wdien he had to do with very irritable subjects. The cases were rare in which he allowed a table- or a teaspoonful to be taken daily from the first solution made with from eight to fifteen tablespoonfuls of water. If he gave a powder, to be taken at once in a spoonful of water, that was always only milk-sugar. He never prescribed two different re- medies to be taken alternately, or one after the other; he would always first learn the effects of one remedy before he gave another, even in patients who were treated by him at twro-hundred leagues distance. Neither did he change the medicines. Even in acute diseases it was rare for him to give more than one spoonful once in the twenty-four hours. But on the other hand, in order to quiet the patient or his friends, he gave frequent doses of plain milk-sugar. Hahnemann appeared in the latter years of his practice to employ his whole dexterity in dimin- ishing the dose more and more. Hence he latterly employed olfaction very frequently. For this end he put one or two globules in a small medicine phial containing two drachms of Alcohol, mixed with an equal quantity of water, which he caused to be inhaled once or twice with each nostril, never oftener. My own wife was cured by him in this manner of a violent pleurisy in the course of five hours. In chronic OF CHANGING THE REMEDY. 163 diseases, happen what might, he never allowed this olfaction to be re- peated oftener than once a week, and he gave besides for internal use, nothing but plain milk-sugar; and in this manner he effected the most marvellous cures, even in cases in which the rest of us had been able to do nothing.” Homoeopathic Notation.—The entire system of potentizing drugs was invented by Hahnemann. He “created potencies out of crude matter, refining the drug into subtile doses, developed the medicinal properties of matter, making them assimilable, and thus specifically curative.” He thus taught, practically, how to cure with the least possible dose, unconsciously but surely applying the general law of the least quantity of action, which was discovered and mathematically established by Maupertuis. The different degrees of potentization have been designated by men each according to his own made of notation,* of which we will only notice those most likely to be generally used. Our own pharmaceutists have a claim to be understood, and we sup- pose their systems of notation are generally known. Of these “Smith numbers his preparations centesimally, but prepares them according to the decimal scale, i. e., with 10 grains of the crude sub- stance he triturates 90 grains of sugar of milk, which he signifies by the fraction -do-. Ten grains of this preparation is again incorporated with 90 grains of sugar of milk, which is designated I., making the first Hahnemannian trituration, centesimal. In this way he makes six tri- turations of an hour each, in preparing what is called the third tritu- ration, which is as high as he carries his triturations generally. They are marked respectively -,-V, 1, 1£, 2, 2£, 3. Expressed in fractions they would be do, iroir? ToVo'j iuh"ctj TiroVinnrj l,o
