In the third Edition, which, for the accommodation of stu- dents, is printed in a small and portable form, a considerable number of new facts and observations have been added from various sources. The more important of the new matter, of an original kind, will be found in cases 7, 26, 80, 85, 96, 121, and 132. In preparing this Edition, the Author has also availed himself of many important observations, which have been added, in the form of notes, to the French translation of this volume, by M. Gendrin. Whenever the name of that eminent individual occurs, the reader will understand that this translation is referred to. Edinburgh, August, 1834. PREFACE. It is a matter of the utmost delicacy for a physician to ob- trude upon the profession his general statements, in regard either to the phenomena of disease, or the action of remedies. The value of such statements does not depend upon his vera- city only, but must likewise rest, in a very great degree, upon the character which he bears as a philosophical observer, and the extent of the observations on which his conclusions are founded. Hence arises the hesitation with which we receive all general statements, when made by persons with whose opportunities of observation and habits of induction we are not acquainted; and the importance which we attach to a simple record of facts, in a concise and accessible form, apart both from hypothesis and system. The author of such a re- cord contributes that which has a fixed and certain value, de- pendent only upon his correctness in distinctly describing what he has seen ; and thus is furnished a series of facts which every practitioner may study for himself, and from which he may acquire a knowledge of phenomena, and of their relations to each other, nearly in the same manner as he does from his own observation. In the revolutions of medical science, there has been, for some years, a progressive and remarkable change of opinion, VI PREFACE. in regard to the mode of conducting medical investigations. There appears to have been a tacit but very general admission of the fallacy of medical hypotheses, and the precarious nature of general principles in medicine; and there seems to be an increasing conviction of the indispensable necessity, of found- ing all our conclusions in medical science, upon an extensive and accurate acquaintance with the pathology of disease. The facts which are required for this purpose can be derived only from the contributions of practical men ; and it is of the utmost consequence that such persons should extensively re- cord their observations, as these must form the only basis on which can be founded any legitimate principles in medical science. General principles in physical science are nothing more than general facts, or facts which are common to all the in- dividuals of a particular class ; and it is only when they are deduced from a correct examination of all these individuals, that they can produce either truth or utility. When they have been framed from a limited observation, they are, in general science, useless, and in medicine, dangerous; and in regard to medical science we may perhaps venture to assert, that the purposes of practical utility are promoted in almost an equal degree, when a principle, which has been proposed is confirmed by the progress of observation, and when one, which has been received upon inadequate grounds, is shown to be fallacious. Influenced by these considerations, the author of the fol- lowing treatise has, from time to time, submitted to the pro- fession a series of researches, on various important subjects of a pathological and practical nature; and he now intrudes upon their attention with farther observations, in a more con- PREFACE. Vll nected and more extended form. In doing so he has no sys- tem to support, and no new doctrines to propose. He may indulge in conjectures, but these he will keep entirely distinct from the facts upon which they are founded. He assumes no higher character than that of a faithful relater of facts, which a practice of considerable extent has brought under his view ; and he aspires to no higher merit, than to contribute some- thing towards enlarging our acquaintance with the phenomena of disease. This volume is divided into four parts. The three first of these refer to diseases of the Brain, arranged under three classes, the Inflammatory, the Apoplectic, and the Or- ganic. This arrangement will probably answer every prac- tical purpose ; for, though the affections of the inflammatory class generally terminate by an apoplectic state, or a state of coma, and the organic affections are often distinguished by apoplectic paroxysms, yet, in a pathological point of view, the classes appear to be sufficiently distinct, for the purpose of an arbitrary division of the subject. The fourth part refers to the diseases of the Spinal Cord, and its membranes; and in an appendix to this part, a slight outline is given of the present state of our knowledge in regard to the pathology of Nerves.

He found her rambling from one subject to an- other with extreme rapidity and considerable incoherence • and on the 5th, she was in a state of the highest excitement with incessant talking, alternating with screaming and singing; MENINGITIS. 51 pulse from 80 to 90. In the evening she became suddenly calm and quite sensible after an opiate ; continued so for an hour or more, then fell asleep, and after sleeping two hours, awoke in the same state of excitement as before. The same symp- toms continued on the 6th; the pulse in the morning was lit- tle affected, but after this time it became small and very rapid. On the 7th, after a night of great and constant excitement, she had another lucid interval, but her pulse was now 150. The excitement soon returned, and continued till four in the after- noon, when she fell asleep. She awoke about eight, calm and collected, but with an evident tendency to coma; pulse 150, and small. She now took food and wine, and passed the night partly in a state of similar excitement, and partly comatose; and died about mid-day of the 8th, having con- tinued to talk incoherently, but knowing those about her, and in general understanding what was said to her. Inspection.—The only morbid appearance that could be dis- covered was a highly vascular state of the pia mater, with nu- merous red points in the substance of the brain. Case XVJII.—A gentleman, aged 44, of a stout make, and very temperate habits, became suddenly affected, without any known cause, with extreme depression of spirits, accom- panied by a good deal of talking and want of sleep. After this condition had continued for two days, it went off sudden- ly, and he recovered excellent spirits and talked cheerfully. This, however, was soon succeeded by a state of excitement, with rapid incoherent talking, and obstinate watchfulness; and the pulse rose rapidly to 160. This state continued with- out abatement for about four days, when he suddenly sunk in- to a state of collapse and died. Inspection.—The only morbid appearance was a highly vas- cular state of the pia mater and arachnoid, with slight serous effusions betwixt them. This obscure and dangerous affection is sometimes met with in connexion with other diseases, especially acute rheumatism and other inflammatory affections, and sometimes attacks fe- males in the puerperal state. It is unnecessary to give a length- ened detail of cases, which do not tend to throw any addition- al light upon the nature of it. A young lady, whom I saw with Mr. Turner, had acute rheumatism in a very slight form for three days, her pulse from 90 to 96 ; on the fourth day, 52 MENINGITIS. the pains ceased, and in the evening, she began to talk a great deal and rather incoherently, but made no complaint. On the fifth day, she was more tranquil, but at night the incoherent talking returned. I then saw her for the first time; she was talking a great deal wildly and incoherently, but, when her at- tention was arrested, she answered questions distinctly; the pulse was 120; the tongue rather loaded, but moist; and she did not complain of any uneasiness. On the sixth day, these symptoms continued; in the evening she became comatose, and died in the night. Bloodletting was employed, and va- rious other remedies, without benefit. A soldier, aged 34, for whose case I am indebted to the late Dr. Hennen, had acute rheumatism in a severe form, combined with pneumonic symp- toms. He was relieved by bloodletting, but his pulse conti- nued frequent, and be had some palpitation of the heart, but not severe. On the fifteenth day of the disease, he became suddenly comatose, and died in a few hours. In both these cases the appearances on dissection were altogether unsatis- factory. The above remarks on this highly dangerous and interest- ing affection, I leave as they stood in the first edition of this work. Since that time I have seen several examples of it, and have been induced to adopt a different mode of treatment, which seems to promise some interesting results. Without at present venturing upon any general conclusions, I shall merely submit the following case. Case XIX.—A lady aged about 38, was recovering from her eleventh accouchment, when, at the end of a fortnight, she became affected with a deep-seated hard swelling in the right side of the pelvis, which was tender to the touch, and was accompanied by a considerable degree of fever. After, repeated topical bleeding and other remedies, the febrile state subsided', the swelling lost its tenderness, and seemed to be gradually diminishing in size; but its progress was very slow, and, af- ter three or four weeks, she was still confined to bed, and suf- fering a good deal of uneasiness; her pulse was now calm, but she was considerably reduced in strength. At this time she became, one day, alarmed and agitated by some family occurrence, and immediately began to talk wildly and inco- herently, and after a restless night was found next day in a state of the highest excitement, talking incessantly, screaming MENINGITIS. 53 and struggling, with a wild expression of countenance, and a small rapid pulse. She was treated by topical bleeding, lax- atives, cold applications to the head, &c, but with little or no benefit; and on visiting her on the following day, I found her sitting up in bed, with a look of extreme wildness, both her hands in constant motion, talking incessantly and wildly; and I learnt that she had not ceased talking for one instant for the last twelve hours. Her pulse was now rapid and feeble, and her countenance expressive of exhaustion. In consultation with a highly intelligent friend who had charge of the case, I mentioned my experience of the fatal nature of the affection, and proposed to make trial of treatment by stimulants. A glass of wine was accordingly given, with evident abatement of the symptoms; and it was ordered to be repeated every hour. At the end of the fourth hour, she was perfectly com- posed and rational, her pulse about 90 and of good strength ; and from this time there was no return of the symptoms. The tumour in the right side increased in size, suppurated, was opened and healed favourably. From this time she continued in perfect health, and has since passed through another ac- couchment in the most favourable manner. This case I have given as another example of this interest- ing affection. I have employed the same mode of treatment, with similar benefit in several other cases, both of males and females. The chief difficulty is in deciding upon the parti- cular cases to which the stimulating treatment is applicable. They appear to be those in which the excitement is accom- panied by a small and rapid pulse, and an expression of paleness and exhaustion. When these characters are present, however violent the excitement may be, I have not been de- terred from the practice, and in a considerable number of in- stances I have found much reason to be satisfied with it. I have tried it, but without the same benefit, in some of the common cases of insanity, accompanied by paleness and bo- dily weakness, but with a natural pulse. When there is frequent and strong pulse, with flushing and other marks of increased vascular action, it would of course be injurious. •An affection analogous to this occurs in habitual drunkards. The symptoms, in such cases, may either follow a particular instance of excess, or they may appear in connexion with some incidental febrile disturbance produced by cold, or any other ordinary cause; and sometimes they follow slight inju- 54 MENINGITIS. ries. There is generally great irritability and restlessness, with sleeplessness or disturbed sleep, sometimes delirium, al- most amounting to mania: and generally a small rapid pulse. This state of excitement may either be followed by sudden sinking and death,—£r it may pass into coma and be fatal more gradually. In other cases there is not the high deli- rium, but a febrile state of restlessness, passing into coma. On dissection there is often little seen, except increased vas- cularity of the membranes, and some serous effusion under the arachnoid, and sometimes a little in the ventricles. In other cases a deposition of puriform matter is found under the arach- noid. An affection occurs in children which presents the same obscurity in the morbid appearances as in these remarkable cases, though with different symptoms. The child is gene- rally attacked with a succession of convulsions, and is cut off within various periods, from one to three or four days. It is apt to occur in connexion with other diseases, especially hoop- ing cough. Case XX.—A child aged two and a half years, affected with hooping cough in a very mild form, was attacked, in the end of May 1822, with a convulsive twisting of the hands, to which she had been formerly liable at an early period of life; this excited no alarm, till the 4th of June, when she was seized with general convulsion, accompanied with fever, headach, and an obstinate state of the bowels. All the usual remedies were employed with activity, but the convulsions continued to recur several times in the day, and she died on the 8th. The cough had gone on, but in a mild and favourable form. Inspection.—There was slight increase of vascularity of the pia mater, with numerous red points throughout the medullary substance of the brain. No other disease could be discovered on the most careful examination, and all the other organs were healthy. Case XXI.—A child aged 5, affected with hooping cough, on the 5th June 1822, was seized with headach and fever; had afterwards irregular motion of the eyes with occasional squinting, then violent convulsions, which recurred frequently and alternated with coma; and he died in three days. After death, nothing could be discovered, on the most careful ex- MENINGITIS. 55 animation, except increased vascularity of the pia mater in several places. Case XXII.—A child, aged three years and a half, had been for several days slightly feverish,^ith some cough, but the complaint was considered as trifliirg, and she was sitting at table on the evening of the third of April, when she sud- denly lost her speech, and soon afterwards was seized with gene- ral convulsion. She continued in a state of constant and violent convulsion, with complete insensibility, for several hours; in the course of the night the convulsion abated—she 'recovered the power of swallowing, which had been lost, and took pur- gative medicine, which operated powerfully. On the 4th, the convulsion returned with great violence; she had a constant succession of paroxysms during the day, and in the intervals was in a state of coma. She died early on the 5th. On in- spection, no disease could be discovered, except increased vascularity of the membranes of the brain, and turgidity of the veins upon the surface. I have notes of several cases resembling this in the symp- toms, and presenting the same obscurity in the morbid appear- ances. They occurred in strong healthy children from two to four years of age, and were fatal generally about the third day, and under various modes of treatment. It is unnecessary to multiply examples of this kind, which only serve to shew us the imperfection of our knowledge on the pathology of the brain. In the following singular case, the affection here referred to seemed to have taken place in the course of another disease of the" brain, and to have been the immediate cause of death, before the primary affection had been so far advanced as to have the nature of it distinctly characterized. Case XXIII.—A child, aged 4 years, of a family who had lost many children from various forms of disease, had been affected for about ten or twelve days, with a feverish disorder, which had not shown any alarming symptom. The complaint appeared to be subsiding, and, on the day on which he died, he had been considered as convalescent by two medical men of the first eminence. In the afternoon of that day, his mother observed that his eyes became suddenly fixed and vacant. 56 MENINGITIS. Soon after, he was seized with most violent general convul- sion, which continued, without intermission, for about five hours, when he died. Inspection.—There was considerable effusion in the ventri- cles, and a good deal of ramollissement of the septum and for- nix. The only other morbid appearance was a most extensive and high degree of vascularity of the pia mater. Inflammation of the arachnoid and pia mater appears to occur in a more chronic form, in which it may go on for a considerable time, spreading from one part of the brain to another, and producing a succession of symptoms, as the parts become successively affected. A lady, mentioned by Mr. Howship,* had severe headach, impatience of light, and para- lysis of the left arm and leg. After a short time the paralysis was removed, but the arm continued so painful as to be nearly useless. The pain of the head continued, and, after two months, extended downwards upon the neck and back. She had then retention of urine, severe throbbing pain of the back and loins, convulsive contraction of the shoulders, and pain shooting through from the back to the breast. She had at last intense pain in the head, neck, back, and whole body, so as to be unable to move a single limb, and died gradually ex- hausted, four months after the commencement of the disease. On inspection, serous effusion was found under the arachnoid, with extensive deposition of coagulable lymph on the upper, lateral, and inferior parts of the brain, and the anterior part of the medulla oblongata: and the same disease was found to have extended along the membranes of the spinal cord. Chronic disease of the pia mater and arachnoid is met with in various forms; in some cases, consisting of thickening of the membranes themselves; in others, with old depositions of false membrane; and in some, the affection is complicated with tubercular disease of the pia mater. A gentleman mentioned by Dr. Powel,f after having been affected for a fortnight with slight headach, became incohe- rent, with a considerable degree of stupor, dilated pupils, and indistinct articulation: and he died in another fortnight. The pupil of the right eye was more dilated than that of the left, and, a short time before his death, the nght side became pa- ralytic. On inspection, effusion was found in the ventricles * Howship's Practical Observations in Surgery and Morbid Anatomy. t Transactions of the College of Physicians of London, vol v. MENINGITIS. 57 and deposition of coagulable lymph about the pons Varolii. At the anterior part of the middle lobe of the brain—he does not say in which hemisphere—the pia mater was much thick- ened, and its inner surface was studded with small tubercles, like large pin heads. Similar tubercles were observed in other parts of it, especially where it lies betwixt the convolutions. This tubercular disease of the pia mater does not appear to be a common affection, but a very remarkable case of it is men- tioned by Dr. Clark.* A man aged 35, addicted to intoxi- cation, was seized with fever and cough, followed by vomit- ing, bloody stools, drowsiness, and muttering; but he was not entirely confined for the first fourteen days ; after this he became worse, with severe headach, much cough, subsultus, drowsiness and deafness, pulse 116, tongue dry and brown. He had then delirium, impatience of light, and a degree cf coma; but he was relieved by bleeding, and the pulse fell to 96. He died'suddenly on the 24th day, having'been out of bed and eating heartily the day before. On inspection, the dura mater was found perforated by small orifices, which trans- mitted flesh-coloured tubercles. These appeared to arise from the pia mater, and had no connexion with the brain ; some of them were of the size of small peas, and were received into depressions of the cranium, some of which were one-sixth of an inch in depth. The arachnoid was thickened, and in some places adhered to the pia mater; in other places, coagulable lymph was deposited betwixt them; there was some fluid in the ventricles. Thickening of the membranes, and adhesions to each other, are met with in many cases, probably the result of inflamma- tory action of old date. Such cases are mentioned by Wep- fer, Willis, and others, in some of which the patients had been long liable to headach. Similar appearances have been ob- served in old maniacal cases. A man is mentioned by Dr. Powel, who had been two years insane, and died fatuous; he had been liable at uncertain intervals, to convulsive attacks, in which the left side of the body suffered more than the right. An adventitious membrane of the thickness of three sheets of writing paper, was found covering the whole right hemisphere of the brain; it became thinner on the lower parts of it, and was gradually lost at the base ; the left hemisphere was entire- ly healthy. * Edinburgh Medical Journal, vol. v. p. 261. 8 58 INFLAMMATION OF THE HEMISPHERES. SECTION V. INFLAMMATION OF THE SUBSTANCE OF THE HEMISPHERES. In the symptoms accompanying inflammation of the sub- stance of the brain, there are considerable varieties, depending probably on the extent of the disease, and the particular part of the brain which is the seat of it. We find in some cases, headach, followed by high delirium, and this by coma; in others, a sudden attack of convulsion. A frequent and very important form of the disease is characterized by headach, followed by convulsion of one or more limbs, the affected limbs afterwards becoming paralytic. Other cases again as- sume a close resemblance to the ordinary attack of hemiplegia, so as scarcely to be distinguished from it; and a very interest- ing feature of the affection in these cases is, that the disease in the brain may not have extended beyond the state of simple inflammation, though the symptoms have passed through their usual course, and have terminated in fatal coma. In the progress of the disease, considerable modifications occur, arising from the various ways in which the inflamma- tion terminates; in these we are chiefly to attend to the fol- lowing varieties. I. It may be fatal in the inflammatory stage;—A certain de- fined portion of the cerebral substance presenting the appear- ance of deep redness without any change of structure. II. The simple ramollissement; which consists in a part of the brain being broken down into a soft pulpy mass, retaining the natural colour of the part, without any appearance of sup- puration, and without fetor. This condition we often find as the only morbid appearance, but we frequently find it combined with the former, one portion of the diseased mass presenting the deep red colour, while another is in a state of ramollisse- ment. III. The preceding appearance mixed with a proportion of purulent matter. IV. The undefined suppuration. This might perhaps be considered as a modification of the former, but with the puru- lent matter predominating in quantity. It, presents a large, ragged, undefined cavity, filled partly with fetid purulent mat- FATAL IN THE INFLAMMATORY STATE. 59 ter, and partly with broken down cerebral substance, the sur- rounding substance being soft and disorganized. V. The defined or encysted abscess. This consists of a well- defined, regular cavity, filled with purulent matter, generally lined by a soft cyst, and surrounded by cerebial matter in a healthy state. VI. Ulceration of the surface of the brain. Important modifications also occur in connection with the character of the disease in regard to activity. In particular, there appear to be some very interesting phenomena, connect- ed with a chronic form of it, in which it may continue for a considerable time without advancing to a fatal termination, or in which the symptoms may remit so as to assume a peri- odical character. These various modifications will be illus- trated by the following selection of cases. § I.--THE INFLAMMATION OF THE CEREBRAL SUBSTANCE FATAL IN THE INFLAMMATORY STAGE. Case XXIV.—A woman aged 26, had laboured under bad health in a variety of forms for 18 months before her death. Her complaints began with severe headach, and frequent at- tacks of convulsion. After some time, these symptoms sub- sided, and she was seized with cough, hemoptysis, quick and laborious breathing, and scarcity of urine. The affection of her breathing came on in paroxysms, during which her respi- ration was 80 or 90 in a minute, and sometimes continued in this state for several days together, her pulse being constant- ly frequent. After she had suffered for many months from these complaints, they subsided entirely without any obvious cause. She then became affected with violent paroxysms of pain in the abdomen, dysuria, and vomiting. The pain was principally in the right side of the abdomen, which was swell- ed, tense, and painful upon pressure ; the paroxysms were succeeded by copious discharges of puriform fluid from the vagina ; and there was a temporary alleviation of the pain af- ter every discharge of this fluid. The last time I saw her, which was a few weeks before her death, there was a general swelling and hardness occupying the whole right side of the abdomen, extremely tender to the touch, and conveying the impression of extensive organic disease. I did not see her in the fatal attack, which was in the head ; it began with se- 60 INFLAMMATION OF THE HEMISPHERES. vere headach, impatience of light, and fever ; these were suc- ceeded by convulsion, and this by coma; and she died co- matose about a week after the commencement of this attack. Inspection.—I was present at the examination of the body, and found the surface of the brain in many places of a dark red colour. This appearance extended in same places to the depth of an inch into the substance of the brain, and was principally observed in the upper and anterior parts of both hemispheres, and on the posterior part of the left hemisphere. The parts so affected were rather softer than the other parts of the brain, and appeared to be more vascular, for drops of blood exuded from them when they were cut. The internal parts of the brain were healthy, and there was no serous effusion. The longitudinal sinus near its posterior part was thickened in its coats, so as considerably to diminish its area. The hard- ness of the abdomen, which was so remarkable a short time before death, had disappeared ; and not a vestige of disease could be detected in any of the viscera of the thorax, abdo- men, or pelvis. Ca se XXV.—A lady aged 40, had been for some time af- fected with irregularity of the menstrual discharge, such as she supposed to be a prelude to its cessation. But, for some days previous to the attack to be now described, the discharge had been present, and very copious, so that she felt weaken- ed by it. This continued on the 26th October, 1825; and, in the evening of that day, on rising suddenly from her chair, she fell down on the floor in a state of syncope, but soon re- covered, and felt no farther inconvenience. She passed ra- ther a restless night, but without any particular symptom, ex- cept that early in the morning she complained of slight unea- siness in the back of her head. Soon after this, she was sit- ting up in bed taking her breakfast with appetite, when, with- out any warning, she fell backward in a state of the most vio- lent general convulsion, with every character of perfect epi- lepsy. The convulsion soon subsided, leaving her in a state of coma ; after a short time, the fit returned, and, from 9 in the morning to 4 in the afternoon, she had about fifteen at- tacks of most severe and general convulsion, without ever re- covering her senses in any degree between the attacks. Dur- ing all this time, she was incapable of swallowing; the eye was insensible, and the pupil rather contracted; the face pale and sallow. The pulse varied exceedingly, being sometimes FATAL IN THE INFLAMMATORY STATE. 61 of good strength, and little increased in frequency ; at other times, especially after the convulsion, it was frequent and fee- ble. General and topical bloodletting were employed with cold applications to the head, &c.; and at 4 p. m. the convul- sions ceased, leaving her in a state of coma, the pulse rather weak. The coma continued during the night, but in the morning of the 28th, she revived a little, began to swallow li- quids, and seemed to take some notice of those about her.— During the day, she generally lay with her eyes open, and at times appeared to follow objects with them, but showed little appearance of sensibility, except that once or twice she named her sister; pulse nearly of the natural standard, and rather weak. She took laxative medicine, by the operation of which she seemed to be relieved, but recovered no farther intelligence. In the night, the convulsions returned in a slighter degree than formerly, but were very frequent, sometimes occuring every 15 minutes. (29th) She was in a state of coma, with appearance of ex- haustion, incapable of swallowing, eye insensible, pupil na- tural, pulse feeble and of natural frequency; after mid-day, she recovered the power of swallowing, but soon lost it again. In the evening, the convulsions returned, with rapid failure of strength, and she died in the night. No paralytic symptom had been observed, and the convulsions seemed to affect equal- ly the whole body. Inspection.—iA small quantity of fluid escaped in opening the dura mater. On the upper surface of the brain, there was a slight appearance of ecchymosis, forming three small patches. On cutting into the left hemisphere, there was found in the upper part of it a round defined portion of. the cerebral sub- stance of a dark red colour; it was about the size of a walnut, distinctly circumscribed, and surrounded by healthy cerebral substance. In its structure, it did not differ in firmness from the other parts of the brain; when cut across, it presented in- ternally the appearance of innumerable small red points, inter- spersed with yellow points, but the red the most abundant. It was situated above the level of the ventricle, about the cen- tre of the hemisphere; and, in the very same situation in the right hemisphere, there was another diseased part exactly simi- lar, except that it was a little softened in the centre. The brain in other respects was healthy, and there was ho effusion in the ventricles. The arachnoid of the base was remarkably vascular on the right side; the cerebellum was healthy. In 62 INFLAMMATION OF THE HEMISPHERES. the centre of the medula oblongata, there was a small dark portion, as if produced by a drop or two of extravasated blood. This remarkable case I saw along with the late Dr. George Wood. The following case seems to be referable to this class; showing the disease in a stage somewhat more advanced, with the first approach towards softening. Case XXVI.—A gentleman aged 36, of very intemperate habits, had suffered repeated attacks of a nature allied to de- lirium tremens, but occasionally accompanied with symptoms of an apoplectic character. In October 1829, he had recently recovered from one of these attacks, and was in excellent health ; went to the country, and was amusing himself with coursing, when, on the 6th November, he was affected with a slight epileptic fit. He had a second attack on the 7th, af- ter which he became considerably incoherent in his conversa- tion, and he had a third and more severe paroxysm on the 8th, in his carriage, on his way to Edinburgh. After the usu- al treatment, he was much better on the 9th, 10th, and 11th. On the 12th, he was excited and restless, walking frequently up and down stairs without any object; and in the evening he had a slight return of convulsion. On the 13th he was confined to bed, and was slightly incoherent. He was again attacked with convulsion at night. On the 14th he was more incoherent; and in the night had a very severe attack, in which he continued in a state of constant convulsion for several hours. Pulse frequent and weak. On his recovery from this pa- roxysm, he remained speechless and with a degree of paraly- sis of the right side ; but he seemed to recognise those about him, and made attempts to express himself.—15th and 16th, continued in the same condition.—17th, there was an increase of the paralysis and the pulse became more feeble. He now sunk into perfect coma and died on the 19th. Inspection.—On raising the brain a very peculiar appearance was presented by the middle lobe of the left hemisphere, which was over its whole surface of a very deep dark-red colour nearly purple. On cutting into it, the same colour was found to extend through its substance, and in a slighter degree into the contiguous portions of the anterior and middle lobes where it was gradually lost in the healthy texture. The part thus CHRONIC FORM. 63 affected was sensibly softer than the sound cerebral substance, but not disorganized or broken down. There was some fluid found in the base of the skull, but the brain in other respects was entirely healthy. § II.--THE AFFECTION IN A CHRONIC FORM. Case XXVII.—A young lady aged 22, was taken ill on the 20th of February, 1817. For the first week, her complaint had the appearance of continued fever ; in the second week, the pulse came down, and the tongue became clean and moist, while the headach continued severe, with a sense of weight, much throbbing in the head, a look of great oppression, and occasional vomiting. Bloodletting, purgatives, blistering, and the application of cold, afforded partial relief; but, on the 5th of March, the pain returned with great severity, accompanied by violent throbbing, and a degree of squinting. The same remedies again procured an interval of partial relief; the pain was not removed, but it was less severe than in the violent paroxysms ; there was constant throbbing in the head, and a look of much oppression; the pulse varying from 84 to 90. On the 11th, there was a violent paroxysm of headach, fol- lowed by convulsion ; she was again relieved by bleeding, but on the 15th, she had loss of recollection, much confusion of thought, difficulty of articulation, and numbness of the right arm and right side of the face,—most remarkable in the latter, which had no feeling when it was touched. These symptoms disappeared on the following day, but the pain continued to recur in paroxysms ; and, about the 24th, had assumed so much of a periodical character, that, by the advice of an emi- nent physician, she was treated with arsenic, which remedy, having occasioned nausea, was given up after a week. She then continued for a fortnight or more, in nearly the same state, constantly confined to bed, and affected with frequent returns of the pain, but without any violent attack, until the 20th of April, when it returned with great violence, accompanied by vomiting, pain in the abdomen, and double vision during the paroxysm; the pulse was at this time natural. From the be- ginning of May, the complaint began to diminish in violence ; on the 20th, she was first able to be out of bed, and from that time recovered gradually. Soon after her recovery, a large glandular swelling appeared upon her neck, which continued 64 INFLAMMATION OF THE HEMISPHERES. stationary for many months. During the summer and the fol- lowing winter, she enjoyed tolerable health, but continued li- able to headach, and throbbing in the head, and required the most cautious regimen. In spring, 1818, she had severe pec- toral complaints, on recovering from which, she began again to complain of headach, with sense of weight in the head, and occasional giddiness. In the beginning of June, she had se- veral attacks which resembled syncope, except that the pulse continued in good strength ; and, soon after this, she began to be occasionally forgetful, and slightly incoherent. These symptoms were followed by a tendency to stupor, which was relieved for a time by purgatives, and repeated blistering; at this time, her pulse was generally from 96 to 100, and her countenance was pale and exhausted. As these symptoms advanced, her pectoral complaints disappeared, and, after va- rious turns of the symptoms in the head, she was found speech- less in the morning of the 3d of July. She lay with her eyes open, appeared to take notice of objects : pulse from 90 to 100 and weak, face pale. She continued in the same state on the 4th ; on the 5th, there was increase of coma, with loss of the power of swallowing, and paralysis of the right side. (6th) Recovered the power of swallowing: pulse 130; ex- pression of the countenance intelligent; eye natural; but she made no attempt to speak. (7th) In the same state; took flowers in her left hand, and appeared to be amused by them; right side paralytic ; great obstinacy of the bowels. (9th) More oppressed. (10) Perfect coma; pulse 130. She died in the evening. Inspection.—The dura mater adhered intimately to the left hemisphere of the brain, at a spot the size of a half-crown piece, about the middle of the hemisphere, near the falx. At this place a portion of the brain, the size of a large walnut, was externally of a deep red colour, and this redness appear- ed both on the upper surface, where the membranes adhered to it, and on the inner surface, where it was in contact with the falx. When cut into, this portion appeared rather firmer than the healthy cerebral substance, except towards the cen- tre, where it was soft, as if approaching to suppuration. The external circumference of the portion retained the deep red colour, to the depth of about half an inch ; the central parts were of an ash colour, with interspersed portions of a dark * reddish-brown. On the upper surface^ where the membranes CHRONIC FORM. 65 adhered to it) there was a deposion of false membrane to the extent of the adhesion, and the dura mater, at the place of the adhesion, was thickened and spongy ; the coats of the longi- tudinal sinus also appeared to be thickened, at the place where it came in contact with the diseased portion of the brain. There was no effusion in the ventricles, and no other disease in any part of the brain. The lungs were extensively tuber- cular, and the pleura lining the diaphragm, on the left side, was rough and irregular, trom numerous small firm excrescences on its surface, resembling warts. Case XXVIII.—A lady aged 60, for whose case I am in- debted to Dr. Hay, in the end of September, 1824, suffered an apoplectic attack with partial paralysis of the right side. She was relieved by bleeding, and appeared to be recovering favourably, until the 8th of October, when she had another at- tack. She did not then become insensible, but complained of a strong pulsation over the body, particularly on the right side, the arm and leg of which were again considerably paralysed. From this time) she gradually lost the power of these parts, first of the leg and then of the arm ; she had occasional returns of the feeling of pulsation, and frequently applied her hand to the right side of her head, in which she said she felt uneasiness, and to which it was observed, that, during sleep, her hand was frequently carried ; the bowels were extremely torpid. The usual treatment was employed by Dr. Hay, in the most judicious manner, without relief; her strength gradually de- clined, and she died on the 26th of December, having fallen into a comatose state, with loss of the power of swallowing, about a week before her death. Inspection.—The dura mater was found to adhere very firm- ly to the brain, at a spot about the centre of the left hemis- phere, on the upper part. The substance of the brain beneath this portion seemed firmer than natural, and) when cut into, was of a bright red colour. This portion was about an inch and a half in extent downwards, and of nearly the same breadth; and the cerebral substance surrounding it appeared more vas- cular than the other parts of the brain. Deeper in the sub- stance of the brain, a similar portion was met with, the size of a hazel nut, which was of a deeper red colour than the for- mer. The corpus striatum of the same size was of a red co- lour, inclining to purple, soft in its texture, and presenting, when cut across, numerous points of vessels. The right hemi- 66 INFLAMMATION OF THF HEMISPHERES. sphere was healthy ; there was a small quantity of fluid in the laterial ventricles ; and, in both ventricles, the chorid plexus was turgid with blood, and contained in its substance nume- rous small cysts of a bluish colour. The vessels on the surface of tba left hemisphere, and betwixt the convolutions, were very turgid with blood; and, in some of the deeper convolu- tions, there was a slight appearance of ecchymosis. § III.—The inflamed mass passing into ramollisse- ment. Case XXIX.—A girl aged 7, had been falling off for about two months before her death, having some cough, with con- siderable emaciation; but her appetite was good. On the 22d of July, 1826, she had pain in the bowels, with diarrhoea, and some vomiting. These symptoms were relieved by the usual remedies, but she still complained of pain in her bowels, and had some cough. Three or four days after this, she com- plained of headach, and her speech was sensibly impaired; about this time, also, she complained of pain in the right ear. Some peculiarity of speech had been observed before on one or two occasions, when she was able to go about. On the 27th, she was first seen by Dr. Beilby, who found her affected with headach and pain of the ear; with considerable embar- rassment of speech, and a small frequent pulse. On the two following days, she was considerably relieved in regard to pain, and the symptoms assumed more the character of con- tinued fever. I saw her on the 30th, when there was consi- derable coma, so that she could scarcely be made to answer a question; pulse 90; the pupil much dilated, and there had been considerable return of headach. On the 31st, she was speechless, with nearly perfect coma; pulse 80. She con- tinued in the same state on the 1 st of August, with the pulse becoming frequent. On the 2d, she began to be affected with paroxysms of convulsions, which attacked only the right side of the body. The limbs of the left side appeared to be para- lytic, or at least were never observed to move, even during the convulsions of the right side. These paroxysms continu- ed to recur for four or five days ; she then sunk into a state of perfect coma, and died on the 10th. She had retained the power of swallowing liquids when they were put into her PASSING into ramollissement. 67 mouth, and seemed to recover a slight degree of motion of the left arm. Inspection.—On removing the dura mater, several patches of false membrane were found on the outer side of the right hemisphere, chiefly at the openings of the convolutions,and dip- ping down considerably betwixt them. On cutting through this hemisphere, a defined portion was met with in a state of re- cent inflammation, presenting a uniform red colour, and a na- tural consistence. It was about 2i inches in length, extend- ing from before backwards, about an inch in breadth, and as much in thickness. At its interior part, it was connected with another portion, about an inch in extent in all its dimensions, in a state of perfect ramollissement, and of a yellowish white or ash colour; and the two structures evidently passed into each other, the inflamed portion becoming gradually softer as it approached the softened part. Along the whole of that part of the hemisphere, through which the inflamed mass extended, all the convolutions were firmly glued together through their whole extent, by a deposition of very firm adventitious mem- brane ; and there was a similar adhesion of the anterior to the middle lobe. There was slight effusion in the ventricles, but the central parts were healthy. In various parts of the brain very minute tubercles were observed ; and, on the base of the brain, at the junction of the left crus cerebri with the tuber an- nulare, there was an irregular tubercular mass of considerable extent, mixed with adventitious membrane. In the lungs there were numerous minute tubercles, all in a solid state. In the mucous membrane of the intestines, especially at the lower extremity of the ileum, there were observed numerous minute black spots, each of which, when viewed by a lens, appeared to be surrounded by a minute circle of inflammation. Case XXX.—A lady aged 24, had long been liable to se- vere attacks of headach, which occurred at irregular intervals, and were excited by various causes, such as warm rooms, and bodily exertions, and for which she had used a variety of treat- ment with little benefit. They had not, however, affected her general health, and she was recoveringfavourably from her se- cond accouchment, under the care of Dr. Mackintosh, when, about the beginning of the second week, she was seized with severe headach, and considerable oppression. She was bled with relief, and continued- tolerably well for several days, though with occasional complaint of headach. On Sunday, 68 inflammation of the hemispheres. 14th January, 1827, after a disturbed night,with some delirium, she complained in the course of the day of slight uneasiness in her head, and a peculiar feeling of numbness in the back of the head and neck ; but she was otherwise well and in good spirits, till about ten o'clock at night, when she suddenly com- plained of numbness and loss of power of the right hand. These feelings spread rapidly along the arm, which very soon became entirely paralytic, and this was speedily followed by loss of speech, and twisting of the mouth. She was immedi- ately bled, and when I saw her soon after the bleeding, I found her with a look of intelligence, but without any attempt at speech; the pulse quick and feeble, the right arm entirely powerless, and with a degree of spasmodic rigidity. A few hours after, the right leg became also paralytic. She continu- ed without any further change till about three o'clock in the morning, when she was seized with severe and general con- vulsion, affecting both sides of the body, but strongest on the left side. The convulsion returned three times betwixt this and mid-day of the 15th, after which the attacks became much more frequent; and from this time she showed no appearance of sensibility. She had from the first swallowed with difficul- ty, but every attempt to make her swallow now excited gene- ral convulsion. During the attacks, the face was much dis- torted, and equally so on both sides ; the limbs of the left side were violently convulsed, while the right arm was affected chiefly with a rigid spasmodic contraction, and a tremulous motion. The convulsions now returned with great violence and frequency, sometimes every half hour, and each attack continued for ten or fifteen minutes. The pulse was generally rapid ; sometimes extremely feeble, and sometimes of tolera- ble strength. • The breathing was sometimes frequent and convulsive, and sometimes slow and oppressed, as if she were moribund ; and on many occasions she was considered as be- ing within a few minutes of death; but she continued to live in this state till the evening of the 16th, being forty-eight hours from the attack. On the second day, the rigid contrac- tion of the right arm had disappeared, and it continued en tirely paralytic, except when it was affected by the convul - sion. Inspection.—On the upper surface of the left hemisphere, and between the convulsions, there was a considerable ecchy- mosis, produced by a very thin layer of extravasated blood betwixt the arachnoid and pia mater. The veins on the upper passing into ramollissement. 69 part of this hemisphere were remarkably turgid, and were found to be distended with dark blood in a perfectly firm fleshy state, mixed with some firm white matter; and their coats appeared to be thickened. Where these veins entered the longitudinal sinus, there was a remarkable diminution of its area, arising partly from the thickening of its coats, and partly from depo- sition of firm white matter on its inner surface. In the sub- stance of the left hemisphere, about the centre of its long di- ameter, towards the outer side, and rather above the level of the ventricle, there was a distinctly defined portion about the size of a small walnut in a state of complete ramollissement, but retaining entirely the natural white colour; and immedi- ately bordering upon this part, there was a considerable por- tion in a state of the deep redness described in the former cases ; the brain in other respects was healthy, except a small soften- ed spot in the right hemisphere. This important case was also seen by the late Dr. Kellie, and Dr. Scott. § IV.—Extensive ramollissement of the corpus striatum. Case XXXI.—A man aged 25, about four years before his death, was first affected with difficult breathing, strong ac- tion of the heart, dropsical symptoms, and irregular pulse ; af- ter some time he was considerably relieved, but about a year and a half after this he again became dropsical, and about this time was suddenly seized with palsy of the left side of the body, delirium and coma. The coma subsided in a few days, and he recovered the use of his limbs in a few weeks, so that he was able to return to his work as a joiner. The symptoms in his chest, however, soon obliged him to give it up, the strong action of the heart continuing, with small irregular pulse, and much dyspnoea. In May 1821, he was again attacked with palsy of the left side, accompanied by coma and delirium, and recovered in a few weeks. In these two attacks of palsy, there never had been any complaint of headach ; but in March 1823, he was attacked with severe headach, followed by loss of memory, palsy of the left side, and coma. He again reco- vered in a few weeks, so as to be able to walk about; the symptoms in the thorax continued as before. 20th October 1823, he was a fourth time attacked with palsy of the left side, 70 inflammation of the hemispheres. accompanied by violent pain referred to a particular spot on the coronal suture, a little to the right side. This was follow- ed by maniacal delirium, the pulse feeble and irregular, the mouth twisted, and the left eye distorted. After some time he recovered considerably, so as to be able to walk with a lit- tle assistance, dragging his leg, but continued to be occasion- ally delirious till a few days before his death, when the palsy again became complete, with much delirium, and some con- vulsive affections, but no coma. He died on the 17th De- cember. Inspection.—There was nothing unusual on the surface of the brain, and no effusion in the ventricles. The right corpus striatum was externally of a peculiar dull yellow colour, and when cut into was found to be throughout its whole substance in the extreme state of ramollissement, extending to a great depth; this was mixed with a slight appearance of pus, and the soft undulating mass was separated from the ventricle by a delicate membrane. There was also ramollissement, but of small extent in the left corpus striatum. The heart was ge- nerally and considerably enlarged ; the right ventricle thick- ened ; the left ventricle enlarged without thickening; the left auricle much enlarged, and containing a large organized po- lypus firmly attached to its sides, and deposited in successive layers like the deposition in the sac of an aneurism. § V.—The affection in a chronic form, with ramol- lissement OF SMALL EXTENT, AND REMARKABLE SYMP- TOMS. Case XXXII.—A gentleman aged 26, of a plethoric habit, had suffered occasionally for two or three years from headach and vertigo, which were always relieved by depletion. On 12th April, 1827, while walking out, he was seized with con- fusion and giddiness, embarrassed speech, and a considera- ble degree of paralysis of the right leg. He was rather pale; his pulse was 70 and soft; and he did not complain of any headach. The usual treatment was adopted with activity by Dr. Combe of Leith, without much relief. On the contrary, after several days he began to complain of acute headach ac- companied by vomiting and hiccup ; and the other symptoms continued nearly as before,—his speech being laboured and slow, and his memory very defective* After some weeks CHRONIC, WITH RAMOLLISSEMENT, ETC. 71 these symptoms subsided, so that he was able to walk out; but the headach continued with frequent vomiting. The pain was chiefly referred to the left side of the head, sometimes to the occiput, and there was occasional numbness of the right arm. When I saw him, along with Dr. Combe and Dr. Kel- ly in July, his chief complaint was of frequent and irregular attacks of vomiting, occurring daily, or repeatedly during the day. It came on very suddenly, without previous nausea, and he was often awaked in the night by the sudden attack of vo- miting. He had now a pale sickly look; there was no para- lytic affection, and little complaint of headach ; though he still had occasional uneasiness in the head, sometimes referred to one part of it and sometimes to another. When he did refer it to a particular part as the principal seat of the pain, it was either the left temple or the occiput. But the headach at this time was slight and transient, and the symptoms in the sto- mach were so much the more prominent, that it was a matter of much doubt whether there was now any fixed disease in the head. The vomiting was much relieved by the subnitrate of bismuth, so that he was free from it for several days. But it soon returned and went on as before, with increasing debili- ty, great listlessness, and bad appetite; pulse little affected. He had now a peculiar unsteadiness of his limbs, so that on first getting up into a standing posture, he staggered very much and required some time and attention to steady himself. When he had accomplished this he walked with tolerable firmness. The symptoms went on in this manner till the 27th of October, when he was suddenly seized with violent 'and continued con- vulsion, and died in nine hours. Inspection.—In the substance of the middle lobe of the left hemisphere of the brain, about the level of the lateral ventri- cle, there was a portion in a state of complete ramollisement, about an inch and a half in length, and an inch in its other di- mensions, and the neighbouring parts appeared unusually vas- cular. The tuber annulare and pons Varolii were softer than usual, but otherwise healthy. No other morbid appearance could be discovered in the head, and all the other viscera were healthy. It is unnecessary to point out the very remarkable features of this case. The sudden attack so closely resembling the ordina- ry paralytic attack, must have been connected with the com- mencement of the inflammatory stage. The remarkable symp- toms in the stomach in the farther progress of the disease, and 72 INFLAMMATION OF THE HEMISPHERES. the mode of its termination, make it altogether a case of great value in the pathology of this remarkable affection. The fol- lowing case shows the same morbid appearance, with a train of symptoms considerably different, but with a remarkable si- milarity in the mode of its termination. Case XXXIII.—A gentleman aged 38, during two years before his death had suffered several epileptic attacks, from which, however, he had always speedily recovered. On the morning of the 27th December, 1827, he was found in bed speechless and paralytic on the right side. He recovered his speech in the course of the day ; the palsy continued in the usual manner, and after some time he began to recover a de- gree of motion of the parts. When he came to Edinburgh about a month after the attack, he had recovered the use of his leg so far as to be able to walk once or twice across his room with much exertion ; his arm was improved in a much less degree; his speech was distinct, but his mouth was con- siderably distorted, and his mind was somewhat impaired. He now consulted Dr. Thomson, and under the usual treatment he was progressively improving, so that at the end of another month he could walk along the streets to a considerable dis- tance, though with a dragging motion of his leg, and could nearly raise his arm to his head. In the evening of 22d Fe- bruary he went to a supper party, and seemed remarkably well; but departed considerably from the abstemious regimen to which he had been previously restricted. About 8 o clock in the morning of the 23d he was found in bed in a state of complete insensibility, accompanied by severe and general convulsion, which was strongest in the limbs of the right side. The face was much convulsed, the eyes rolling and insensible, the respiration laborious and convulsive. Bloodletting and the other usual means were actively employed without any re- lief. The convulsion continued unabated in the state now described, when I saw him at eleven, and he died at two. Inspection.—The brain externally was healthy, except some old adhesion of the membranes near the posterior part of the falx, and very trifling effusion under the arachnoid. The ven- tricles contained the usual very small quantity of fluid. On the outer side of the left ventricle, and separated from it by a thin partition of healthy cerebral substance, there was a defin- ed portion in a state of complete and diffluent ramollissement. The portion thus affected was about an inch in depth ; about CHRONIC, WITH RAMOLLISSEMENT, ETC. 73 half or 3-4ths of an inch in diameter at the upper part, and became gradually narrower as it descended by the side of the ventricle, until it terminated almost in a point. There was considerable softening of part of the medulla oblongata, and the upper part of the spinal chord. 'No other vestige of dis- ease could be discovered on the most careful examination. I do not attempt to offer any explanation of the symptoms in these two most remarkable cases, or to reconcile them with the old notions in regard to diseases of the brain. I give them as facts carefully ascertained, and faithfully related, to be illustrated by farther observations on this very remarkable disease. § VI.—The affection in a chronic form, with ex- tensive ramollissement, AND, REMARKABLE DISEASE OF THE BASILAR ARTERY. Case XXXIV.—A young man aged 18, had been for six or eight weeks affected with cough and pain of the chest, and was supposed to be phthisical; but for several days he had been much better, when on the 15th December 1819, he sud- denly fell down deprived of sense and motion, and paralytic on the left side, with twisting of the mouth. When partially recovered, he complained of severe pain in the right temple; his speech was very indistinct; countenance expressive of great stupor. The usual treatment was actively employed, but without much benefit, and he continued for about ten days with little or no improvement; the left side perfectly paralytic ; a great degree of coma ; the speech very indistinct; but he still pointed to the right temple as the seat of fixed uneasiness. During this time his pectoral complaints had disappeared. In January 1820, he began to improve, so as to have less unea- siness in his head, and considerable motion of the leg, but the arm continued entirely paralytic. His cough now returned, with considerable pain in the right side of the chest. He con- tinued without farther change till the 15th of February, when he complained of pain in the back of his head, and was seized with loss of speech, and of the power of swallowing. He soon recovered his speeeh, but the power of swallowing was permanently lost, so that from this time he was constantly fed by liquids introduced into the stomach through an elastic gum tube. He was now quite distinct, and did not Gomplain of 10 74 INFLAMMATION OF THE HEMISPHERES. any pain ; the cough again abated; pulse of natural frequency, but feeble. In the beginning of March he seemed to improve a little in strength, so that he was several times taken out in a carriage ; there was considerable motion of the left leg, but the arm continued perfectly paralytic ; no return of the power of swallowing; speech and intellect entire. He died rather suddenly on the 20th of March, having the day before become extremely weak and pale without any obvious cause. Inspection.—On removing the dura mater, there appeared on the middle of the right hemisphere a remarkable depression, which, when cut into, was found to arise from an extensive mass of pure ramollissement; the part being in the state of a soft white pulp, without any appearance of pus, and without fetor; it extended the whole depth of the hemisphere. In the cerebral matter adjoining to this disease, there was a small abscess, no larger than a bean, lined with a firm soft cyst of coagulable lymph. There was very little effusion in the ven- tricles, and no other disease in the substance of the brain. On raising the brain, a remarkable appearance was found in the basilar artery; through the extent of about an inch it was very much enlarged and hard, and this portion was found to be completely filled up by a firm white matter without any ap- pearance of blood. Anterior to this portion, there was a small coagulum of blood in the artery. The lungs were tolerably healthy, but there was a considerable deposition of coagula- ble lymph, forming a thick firm mass betwixt the right lung and the pleura costalis at the lower part immediately above the diaphragm. § VII.—Ramollissement combined with suppuration. Case XXXV.—A man aged 24, had been liable for two years to headach, which was always referred to the right side of the head. In February 1818, he contracted syphilis, which, being neglected, became inveterate, and continued fourteen months. During this time the headach became more severe, and was always referred to the right temple. In June 1819, he was affected with numbness of the left thumb, which gra- dually extended over the arm, and he had afterwards complete paralysis of the left arm and leg, with severe pain in the right temple. This was followed by maniacal delirium, which con- tinued for three days. He was relieved by copious bleeding, with ramollissement and suppuration. 75 &c, and was completely recovered within a month. In Au- gust, he was affected in the same manner, and again entirely recovered. He continued well till 27th November, when he complained of violent pain over the whole head, and in the night was observed to have lost his speech and the power of his left side; the jaws were locked; he appeared sensible, and expressed his feelings by signs; pulse 98, small and ir- regular. There was no change on the 28th; on the 29th, the body was rigid as if tetanic; he then became comatose, and died in the evening. Inspection.—The anterior and lower part of the right hemis- phere was extensively diseased, forming a mass in which soft- ened cerebral matter was mixed with pus of intolerable fetor. There was very little fluid in the ventricles, and no other dis- ease could be detected in any part of the brain. § VIII.—Undefined suppuration. Case XXXVI.—A gentleman aged 18, had been for many years affected with a considerable degree of deafness, and had been liable to suppuration of the ears. In 1810 he was affect- ed with a chronic abscess behind the left ear, by which a probe could be passed to a great depth into the cells of the mastoid process. This sore discharged more than a year and then healed, leaving a deep cicatrix. From this time he was lia- ble to headach, which became more severe in the beginning of the year 1813. May 14, 1813, after having been for some days languid, and complaining a little of his head, he was seized with severe headach and frequent vomiting. He was much oppressed, and lay in a dozing state, impatient of being disturbed; pulse 60. He was treated in the usual manner, by free, general, and topical bleeding, purgatives, blistering, &c. On the 15th the headach was still violent, but the vomiting had abated; pulse 60; had several severe attacks of shivering, was op- pressed and disposed to sleep, but sensible; eyes natural. (16th) Headach relieved ; increasing oppression. From this time he lay in a state of partial stupor, with much talking, which was generally coherent; pulse varying from 80 to 120. He died on the 22d, rather unexpectedly, and without perfect coma. He had continued to know the persons about him till about twelve hours before his death. His sight continued na- 76 inflammation of the hemispheres. tural except on the day of his death, when he appeared to be blind : no paralytic affection, and no convulsive symptom had been observed. Inspection.—The right hemisphere of the brain, to about half its depth, was entirely reduced to a mass of fetid pus; in the centre it was fluid, and towards the external parts it was more of a pulpy consistence. In this mass, there were found some small coagula of blood, and the ventricles contained a considerable quantity of bloody fluid. Case XXXVII.—A gentleman aged 18, (10th July, 1815,) was affected with violent headach, extending along the upper and back parts of the head, and accompanied by severe pain in the neck, where it was much increased by the motion of the head. There was much oppression ; pulse natural; face rather pale; tongue clean ; eyes natural. He had been ill three days, and the complaint had commenced with shivering; he had been many years affected with deafness, and liable to suppuration of the ears. The usual practice was employed; general and topical bloodletting, purgatives, blistering, &c. The bleeding gave great relief at each repetition of it, and the blood was sizy; but the relief was transient. On the 13th, he had squinting and double vision, which continued on the 14th, but then went off and did not return. The headach continued with many variations in degree; sometimes he made little complaint, and at other times, was in violent pain; there was sometimes a degree of delirium, but it was slight and transient; there was much oppression but no coma, and no paralysis. He died on the 17th rather suddenly. At my last visit, he had raised himself in bed with little assistance, answered ques- tions distinctly, and knew every person about him ; pulse 60; sight natural. His death occurred a few minutes after I had left the house. Inspection.—The whole of the posterior part of the left he- misphere of the brain was one mass of undefined suppuration. There was considerable deposition of coagulable lymph on the surface of the brain in several places, especially under the an- terior lobes. There was a very small quantity of fluid in the ventricles, and considerable ramollissement of the fornix. In the substance of the brain, near the base, there was a small tumor of an ash-colour, which contained a cheesy matter ap- proaching to suppuration. A portion of the dura mater co- vering the temporal bone behind the auditory portion was with undefined suppuration, etc 77 thickened and spongy, and there was slight appearance of ca- ries in the portion of the bone with which the diseased mem- brane was connected. Dr. Bright has described a remarkable case, in which a mass of this kind of undefined suppuration occupied nearly the whole of the right hemisphere. The case began with puer- peral convulsions, after which the patient lay for seven days, with very obscure symptoms, and sensible, till she died sud- denly after violent convulsion. § IX.—Extensive undefined suppuration with extra- VASATED BLOOD. Case XXXVIII.—A man aged 40, had complained for two months of frequent pain and throbbing in the left side of his head. In March 1814, he began to be affected with convul- sive motions in the right arm and leg, which attacked him in paroxysms, and usually continued about a minute, leaving him in the intervals able for his usual empfoyment as a blacksmith. After bloodletting and purging, these paroxysms became less frequent, and after eight or ten days ceased. He was then affected with giddiness and confusion of thought, and consi- derable torpor of the right side. After some time, this was at- tended with motions, in the right arm and leg, exactly resem- bling those of chorea. The muscular power of these parts was at the same time diminished, and, at the end of two months from the first appearance of the spasmodic affections, the arm and leg became entirely paralytic. His speech was then affected, being first inarticulate, and afterwards gradually lost, so that after the middle of June he never was able to ar- ticulate a word. His pulse, which till this time had continu- ed quite natural, now became a little frequent; he passed his urine and feces involuntarily, but his mental faculties seemed to be entire. He took food when it was offered him, and put out his tongue when desired; his eye was natural, and the expression of his countenance intelligent. His sight and hear- ing appeared to be perfect, but he never attempted to speak. He often screamed as if from pain, at the same time laying his hand on his forehead, and frequently shed tears. He con- tinued in this state till the end of July, when he became coma- tose, and died in three days. Inspection.—On removing the dura mater, the1 left hemis- 78 inflammation of the hemispheres. phere of the brain felt soft and fluctuating through its whole extent like a bag of fluid; on cutting into it, there was about half an inch in thickness of sound cerebral substance, the re- mainder of the hemisphere was found nearly reduced to a fluid mass, partly consistent of purulent matter, and partly of cere- bral substance, in a soft pulpy state ; but the greater part was purulent. From this mass of disease, the ventricle was sepa- rated merely by the membrane which lines it, and contained a small quantity of serous fluid. In the substance of the left thalmus, there was a coagulum of blood, of the size of a wal- nut. § X.—The encysted abscess. Case XXXIX.—A girl aged 11, thin and delicate, after having complained for some days of headach, was seized on the 11th of January, 1817, with convulsion, which continued about half an hour. I saw her on the 12th, and found her af- fected with severe heSdach, and paralysis of the right arm, which had taken place immediately after the convulsion. The pulse was 100; the tongue foul; the face rather pale, and the eyes languid. Being bled from the arm and purged, and cold being applied to the head, she was much relieved. On the 13th, the pulse was natural, the headach was much abated, and she had recovered considerable motion of the arm. On the 15th, the headach being increased, and the arm more pa- ralytic, she was bled again; and on the 16th and 17th, she was much relieved, the pulse natural, and the motion of the arm much improved. On the 18th, after being, affected with increase of headach, and some vomiting, she became convuls- ed, the convulsion being confined entirely to the head and right arm. The head was drawn towards the right side with a rolling motion of the eyes, the arm was in constant and vio- lent motion ; she was sensible, and complained of headach; pulse 100. Being bled to 8 ounces the convulsion ceased in- stantly, and the headach was relieved, but the right arm con- tinued in a state of complete paralysis. (19th and 20th) The arm had recovered a little motion \ some headach con- tinued, with occasional vomiting; pulse 60. On the three following days, the convulsive attacks returned several times; they did not now affect the head or face, but were entirely confined to the right arm, which, after the 23d, was left in a WITH ENCYSTED ABSCESS. 79 state of permanent paralysis. Hitherto no other part of the body had been affected by the convulsion; but on the 24th, it attacked the right thigh and leg, and left them in a state of paralysis; pulse 60. The former remedies were again em- ployed with activity, without any effect in arresting the pro- gress of the disease. The thigh and leg now went through a course precisely similar to that described in regard to the arm, and on the 29th, remained in a state of permanent paralysis. When the convulsion first began to affect the leg, the arm was affected at the same time ; but afterwards it was confined to the thigh and leg, the arm remaining motionless. February 4th. Complete paralysis of the whole right side; no return of convulsion; she continued quite sensible, and made little complaint; pulse from 50 to 60. She now con- tinued for several days without any change, and except the palsy of the right side, every function was natural. She was quite sensible, appetite good, pulse and vision natural, and she made little complaint of any uneasiness. She was, how- ever, inclined to lie without being disturbed, and gradually became more oppressed. On the 11th, this had increased to perfect coma, in which she continued for three days, and died on the 14th. Inspection.—In the upper part of the left hemisphere of the brain, there were two distinctly defined abscesses, containing together from six to eight ounces of very fetid pus. They were lined by a firm white membrane, and a thin septum of firm white matter separated them from each other; the one was in the anterior part of the hemisphere, very near the sur- face, and the other immediately behind it; they had no com- munication with each other, or with the ventricle. In the posterior part of the right hemisphere, there was a small ab- scess containing about half an ounce of pus. There was no serous effusion in any part of the brain, and no other morbid appearance. Case XL.—A gentleman aged 21, had been for many years affected with cough and puriform expectoration, which was often in considerable quantity; he had also had repeated attacks of haemoptysis, some of tiem copious. He was stint- ed in his growth, and of a feeblenabit, but in other respects enjoyed tolerably good health, and was able to attend to his business as clerk to a solicitor, till the beginning of July 1822, when he began to complain of headach. For some time be- 80 INFLAMMATION OF THE HEMISPHERES. fore this he had observed occasionally, while sitting at his desk, a deficiency of sight, but had taken little notice of it. This illness began with headach, loaded tongue, and quick pulse, and so continued for eight or ten days without exciting any alarm. He was treated in the most judicious manner by Mr. Johnston, and seemed to be recovering gradually, the pulse coming down, and the headach being considerably re- lieved, though not quite gone.. I saw him about the 15th. The pulse had then fallen to 50, he was feeble and languid, with some headach, and a look of oppression. The pupil was rather dilated; there was an evident imperfection of vision, and about this time there was first observed a weakness of the left arm and leg. The headach had been at first referred chiefly to the left side of the head, but now it was principally on the right side, though he often described it as extending across the forehead. The cough continued, with considerable expectoration of a tenacious puriform fluid. There was no pain in the chest, and no uneasiness in breathing, but the pulsation of the heart was felt entirely in the right side of the thorax. This peculiarity had been observed for several years, but it could not be ascertained at what period it had com- ' menced. His pulse, was now feeble and languid, and his general ap- pearance pale and exhausted. For several days there was little change, the pulse continuing about 50, sometimes 48. After three or four days there was a slight convulsive attack, and a second about two days after; these, however, made no change in the symptoms. About the 24th there was some incoherence, but it was slight, and soon went off. The pupil was still considerably dilated, though sensible to the light; a degree of headach continued, but it was not much complained of. He was now disposed to lie without being disturbed, but when spoken to was quite intelligent. About the 26th, there was a remarkable improvement in his appearance, and much less headach, the pulse beginning to rise. (27th) Pulse 108; more comatose, but sensible when roused. (28th) Pulse 120; had copious purulent expectoration in the morning, and seemed much exhausted. He lay much oppressed, but when roused answered questions ^stinctly. He could still move the left arm, but slowly and With difficulty, and with an awk- ward motion, somewhat resembling that of chorea, or as if he threw the whole arm forward by a strong effort of the muscles of the shoulder; he had seldom attempted to move the leg for WITH ENCYSTED ABSCESS. 81 several days. In the course of this day there was observed a slight degree of squinting; and he died in the night without any other change. Inspection.—The brain was externally healthy. In the up- per and anterior part of the right hemisphere, very near the surface, there was an abscess containing about an ounce of very fetid pus. In the posterior part of the same hemisphere, there was another abscess rather smaller. These abscesses were distinctly defined, but not very distinctly lined by a mem- brane, and the cerebral matter surrounding them was slightly softened. In the anterior part of the left hemisphere, imme- diately under the surface, and at the very angle of it, which lies over the orbit, there was a small abscess containing from one to two drachms of pus, and another rather larger in the pos- terior part of the hemisphere. These abscesses were all above the level of the ventricles, except the one in the posterior part of the right hemisphere, which went down a little behind the ventricle. The ventricles were empty, and there was no other disease in the brain. The right lung was reduced to a small dark-coloured mass, resembling the spleen, and inter- nally presented a series of abscesses, communicating with each other, and with the trachea. The heart lay in contact with it on the right side of the thorax; and the left lung was so en- larged as to fill all the remainder of the cavity. It was quite healthy, except a small tubercular mass in a firm state, in the upper part of it. The following case shows the encysted abscess with symp- toms remarkably different from those mentioned in the preced- ing cases. Case XLI.—A man aged 43, had complained of headach for ten days, but had not been prevented from following his usual employment. At one o'clock in the morning of the 9th May, 1827, he was seized with palsy of the left side of his face, and became incoherent and unmanageable. When he was seen some hours afterwards by Dr. Huie, these symp- toms continued; the pupils were contracted, and the eyes were in perpetual motion ; the skin hot; the pulse 90, full and strong. There was no palsy of any of the limbs, but, on the contrary, he made the most powerful resistance when Dr. Huie attempted to bleed him, which, however, he accomplished to the extent of thirty ounces. In the afternoon there was 11 82 INFLAMMATION OF THE HEMISPHERES. considerable coma with stertorous breathing, but both these symptoms disappeared after another bleeding. On the 10th, the palsy of the face was gone, but he was still incoherent and restless; pulse 100. Topical bleeding was employed, and purging with croton oil, &c. On the 11th, he was co- herent and quiet, pulse 108; but he became incoherent in the afternoon. On the 12th, he was sometimes drowsy and some- times restless; pulse 120 and small. He died in the night. Inspection.—Three abscesses were found in the brain, all completely encysted, and filled with well formed pus. The first was in the anterior lobe of the left hemisphere, and con- tained about three drachms of pus. The second was in the pos- terior lobe of the same hemisphere; it was considerably larger, and had burst into the ventricle, which was filled with the matter. The third was in the posterior part of the right hemi- sphere, and appeared to be making its way towards the sur- face. A still greater obscurity of symptoms occurred in the fol- lowing remarkable case, for which I am indebted to Dr. Al- lison. It occurred under his care in the Clinical Ward, in June, 1827. Case XLII.—A man aged 26, was seized with shivering, headach, sickness, and sudden loss of strength, with fits of delirium in the night. Two days after the occurrence of these symptoms, he was admitted into the Clinical Ward. At this time, he was able to walk when supported on one side, but with feebleness and difficulty, his legs, particularly the right, being at each step dragged along, rather than raised from the ground; his expression was dull and listless, but he said he was free from pain. A few hours after, he complained of vio- lent pain in the occiput, with frequent vomiting. The pain was relieved by a bleeding. In the evening he was oppress- ed, and answered questions slowly and with difficulty; there was still some headach, with nausea; the skin hot and dry; the pulse varying from 80 to 100, sharp, and moderately full; tongue dry; pupils natural; respiration somewhat short and hurried. About half an hour after this report was taken, he sunk into perfect coma, with dilated pupils, for which another bleeding was employed without relief, and in less than an hour he died. Inspection.—The brain was externally of a reddish-brown ABSCESS OF THE CORPUS STRIATUM. 83 colour. On the right side of the vertex, there was a spot the size of a half-crown of a greenish yellow colour. On remov- ing a very thin portion from this spot, an irregular abscess was opened, which contained well formed pus, and which seemed to be entirely limited to the cineritious substance. In the posterior part of the left hemisphere, on a level with the corpus callosum, there was another abscess, which seemed to be seated in the medullary matter, and was surrounded by softened cerebral substance of a livid yellow colour. In the posterior part of the right hemisphere, there were two other abscesses, one in the cortical substance, and the other in the medullary. Here also a fifth abscess was found, of a very small size, being about the size of a pea, but surrounded by a more defined cyst than any of the others; there was exten- sive ramollissement of the formix, septum lucidum, and the lower part of the corpus callosum. The left corpus striatum was softened, and had a greenish-yellow colour; the surface of the left thalamus was ragged and almost fluid, but retained its natural colour. § XI.—Abscess of the corpus striatum of very small EXTENT. Case XLIIL—A gentleman aged 33, in January,|1817, had a severe attack of pneumonia with symptoms of carditis, from which he recovered perfectly, after having been4bled to the extent of 160 ounces in five days. For sometime after he felt his breathing a little uneasy, but this gradually subsid- ed ; and he enjoyed very good health till the middle of Feb- ruary, 1819, when, on awaking one morning, he found his whole left side numb and insensible, but without any remark- able diminution of motion. The loss of feeling extended along the half of his face, the line being drawn with much precision along the centre of the nose ; he had no other complaint; had no headach, and the pulse was natural. He was freely bled and purged; the symptoms then gradually subsided, and in four or five days were gone. From this time, however, his friends remarked that he was less acute in business than for- merly, and that his memory was somewhat impaired. In the month of May, this deficiency rather increased; and, about this time, he complained of slight uneasiness in his head, for which he was again bled. He continued, however, to attend 84 ABSCESS OF THE MEDULLA OBLONGATA. to his business as a solicitor, till the 16th, when he appeared considerably confused, and complained of his head ; his pulse was now feeble, so as not to indicate farther general bleeding. After a purgative and topical bleeding, he was much relieved, and in the evening was quite distinct and made no complaint. About two in.the morning of the 17th, he was heard to make a remarkable noise in his sleep, which was found to be owing to a kind of convulsive breathing. This was speedily follow- ed by perfect coma, with loss of the power of swallowing. He lay in this state till nine o'clock at night, and then died. All the usual remedies had been employed without the slight- est effect. Inspection.—Every part of the brain was found in the most healthy state, till we came to the left corpus striatum; in the lower part of this there was a small irregular abscess, not ex- ceeding the size of a small bean, containing purulent matter of remarkable fetor. In the centre of the right corpus striatum, there was also discovered a minute abscess regularly and nice- ly defined, but no larger than a small pea. No other disease could be detected in any part of the body. § XII.—Abscess of the medulla oblongata. Case XLIV.—A child aged 16 months, whom I saw only a week before his death, had been in a declining state of health for ten months. The beginning~of his bad health was ascribed to a fall, in which he was supposed to have sustain- ed an injury of the back part of the head or neck. From this time he was often much oppressed, and had been gradually wasting. Three months before the time when I saw him, he had squinting, and appeared to lose the power of the right arm and leg. The squinting went off after some time, but af- terwards recurred occasionally. The use of the arm and leg was never entirely recovered. These always appeared weak- er than the limbs of the other side, and he seldom attempted to raise the arm at all. He had also suffered occasionally slight convulsive affections. When I saw him there was no very marked symptom, except considerable emaciation: the pulse was frequent, and the bowels very confined. Much dark coloured matter having been evacuated from his bowels he seemed to be relieved. After some days, there was a remark- able slowness of the pulse, and in the course of the same day abscess of the cerebellum. 85 he was attacked with violent convulsion. This recurred seve- ral times during two days, and then proved fatal. There was no coma; the eyes continued sensible during the intervals; and he took notice of objects a very short time before death. Inspection.—There were several ounces of fluid in the ven- tricles of the brain. In the substance of the medulla oblon- gata, where it is crossed by the Pons Varolii, there was an abscess which appeared to occupy its whole diameter. It had the appearance of a scrofulous abscess, and was contained in a cyst, the inner surface of which was of a yellow colour, and had an appearance of ulceration. There was considerable disease in the glands of the mesentery. § XIII.—Abscess of the cerebellum. Case XLV.—A young lady aged 18, was seized on 4th March, 1813, with inflammation of the bowels. The inflam- matory symptoms were subdued by two full bleedings, but the bowels continued very obstinate, and were not moved in a satisfactory manner till the 12th. During this time, a varie- ty of purgatives had been given, with repeated tobacco injec- tions ; and by calomel, given as a purgative, her mouth had been affected as early as the 7th. From the beginning of the attack, she had been affected with pain in the left ear, and about the 7th began to com- plain of headach. This was at first slight, and, amid the urgency of her other symptoms, excited little attention. It in- creased, however, and on the 11th had become violent, so that she lay pressing her temples with her hands, and screaming from pain. The pulse was at this time natural, and she was free from vomiting and uneasiness in the bowels. On the 11th, there was a considerable discharge of matter from the left ear. On the 13th, the pulse rose suddenly to 160, and there was such a degree of sinking as required the use of wine. The pulse soon subsided, so that on the evening of the 14th it was at 80, and on the 15th at 60. The headach continued una- bated. On the 14th, there was a tendency to coma, which was increased on the 15th, with dilation of the pupil. There was now little room for active treatment; and topical bleed- ing, blistering, &c, were employed without relief. On the 16th, the pulse began to rise again, but was very variable, in the course of a few minutes varying from 80 to 120. She lay in 86 ulceration of surface of the brain. a state of great oppression, but when roused talked Sensibly ; headach still severe. (18th) Had lost the power of swallow- ing, but often asked for drink, though she was nearly suffo- cated in the attempt to swallow it; the pulse varying from 90 to 150. (19th) Squinting and dilated pupil; pulse varying from 96 to 160. (20th) Squinting increased; swallowed a little once or twice with effort; at other times was nearly suf- focated in attempting it; was still quite sensible when roused, and complained of violent headach. She now sunk gradual- ly, and died on the 22d; she had continued sensible when roused, arid knew those about her till an hour before her death. She had also retained the sense of sight, though the pupils were much dilated. Inspection.—The surface of the brain was natural; the sub- stance showed marks of increased vascularity, and the ven- tricles were distended with colourless fluid. The left lobe of the cerebellum was entirely converted into a bag of purulent matter, of a greenish colour and intolerable fetor. It was contained in a soft and organized sac, which appeared to be of recent formation. A portion of the dura mater on the outer side of the abscess was thickened and spungy ; the bone was sound ; the caput coli, and about eighteen inches of the extre- mity of the ileum, were of a dark livid colour, but sound in their structure. Another case of abscess of the cerebellum has been describ- ed under a former article.—See Case III. § XIV.—Ulceration of the surface of the brain. This appearance is uncommon, but it is distinctly describ- ed by several writers. A man, mentioned by Dr. Scoutetten, had violent headach, followed by great disturbance of the stomach and prostration of strength. He was relieved by topical bleedings, &c. ; but, after a week, the symptoms increased, with fever, and the pain was so violent as to produce scream- ing. In this manner he went on without relief, and died on the twenty-sixth day,—no other symptoms being mentioned, excepting that he lay with his eyelids closed, and his fore arms bent. On the lower part of the anterior lobe of the right hemisphere of the brain, there was a superficial ulcer measur- ing 13 lines by 7. It was of a yellowish appearance, and its review of the subject. 87 edges were unequal and ragged. The dura mater and the pia mater covering the spot were destroyed by erosion, and the pia mater was in some other places inflamed ; the brain in other re- spects was healthy. A similar appearance on the posterior part of the brain was observed in a man who died of protract- ed intestinal disease ; he had been affected for three days be- fore his death with oedema of the forehead and left eyelid, headach, delirium, and convulsive motions of the upper extre- mities.* The same appearance in the cerebellum is mention- ed by Mr. Howship.f A soldier at Gibraltar lay down and fell asleep in the sun in a very hot day; he soon awoke in great pain, and was confined to bed for six weeks, with con- stant and violent pain in the forehead. He then returned to his duty, and was not heard of for six months, when he went into the hospital again, affected with pain in the forehead. It now became remittent, generally returning every morning, but sometimes missing a day, or varying in the hour of attack; there was no fever. Two months after his admission he be- came suddenly delirious in the night, and soon after expired. On dissection, there appeared a general increased vascularity of the brain, without any decided disease, until the tentorium was raised, when there appeared upon the upper surface of the cerebellum an ulcerated superficial excavation, the size of a shilling, containing a thin ichorous matter. The pia mater at this place was destroyed, and the dura mater was discoloured. Dr. Bright has also given two examples of defined ulceration of the surface of the brain, with loss of substance. In one of them the symptoms were very obscure. In the other, the af- fection followed an injury of the pericranium, and was fatal af- ter several weeks. The cases described under Section V. appear to illustrate the principal phenomena connected with inflammation of the substance of the hemispheres. In Case XXIII. we see it in its recent state on the surface of the brain, and in Case XXIV. we find it in the substance forming a distinctly defined por- tion in a state of active inflammation. In Case XXVII. we * Arch Gen. de Med. January, 1825. t Med. and Phys. Journal, March, 1810. 88 inflammation of the hemispheres. see an inflamed portion of this kind passing gradually into ramollissement; and in Case XXVIII. we see the ramollisse- ment in a more advanced state. In the subsequent cases, we see more complete ramollisement, both uncombined and mixed with purulent matter. We then find the inflammation passing into a distinct and encysted abscess; and finally we observe it terminating by ulceration of the surface of the brain. Of the cause of these varieties of termination we at present know very little. I have thrown out a conjecture that the ramol- lisement occurs chiefly in the white matter, and suppuration in the gray; but it is mere conjecture. That the ramollisse- ment, however, is a result of inflammation, I think the appear- ances described in some of these cases place beyond a doubt. I have already stated my belief that it also arises from another cause, namely, disease of the arterial system, being thus ana- logous to gangrene in other parts of the body, which we see arising from these two very opposite causes. In this manner I have proposed to reconcile the diversities of opinion which at present exist among pathologists in regard to this appear- ance. In the symptoms which accompany inflammation of the substance of the hemispheres, there appears to be such a di- versity as must prevent us at present from attempting any ge- neral statement of them. The most common appear to be headach followed by convulsion, either of one limb, or of a more general kind ; or a sudden attack of convulsion, without previous complaint of pain, the convulsed parts afterwards be- coming paralytic. But in Case XXIV. no paralysis was observ- ed after three days of the most frightful convulsion ; while in Case XXVIII. paralysis was the first symptom, and convul- sion took place at a subsequent period. In other cases, again, we find paralysis of one side of the body and convulsion of the other. On this interesting subject, however, we have not at pre- sent a sufficient collection of facts to enable us to advance to any general statement in regard to the symptoms, or to refer particular symptoms to the particular seats or terminations of the disease. But there are numerous .facts of very great in- terest which deserve to be recorded, without attempting any thing farther than a simple statement of them in connexion with the principal morbid appearances. They refer chiefly to the affection in the various conditions of simple inflammation ramollisement, suppuration, and ulceration ; and to some inte- REVIEW OF THE SUBJECT. 89 resting phenomena connected with the disease in a chronic form. I. In the state of Simple Inflammation, the affection seems in general to be characterized by headach and convul- sion ; but in a more chronic form of it, as in Cases XXV. and XXVI., we see it productive of paralysis, without convulsion, and fatal in a state of simple inflammation, with all the symp- toms of perfect apoplexy. On the other hand, in Case XXVIII. the palsy preceded the convulsion. In some of the cases which terminated by the encysted abscess, there is reason to believe that the inflammatory stage was characterized by con- vulsion of one or more limbs, followed by temporary para- lysis, and that the permanent paralysis, took place when the disease passed into suppuration. In some of the other cases, again, it seems probable that the inflammatory state was productive of an attack of palsy, exactly resembling the ordi- nary hemiplegia from other causes. This probably took place in the very interesting case, (No. XXXII.) Of the disease in its more chronic form, an important example is related by Dr. Treutler.* A woman aged 30, had been ill for two months with dropsy, which had followed intermittent fever, and was connected with disease in the spleen. In the third month of her illness, she complained of a feeling of weight in the occiput towards the right side, with dimness of sight, and a great propensity to sleep. Her hearing became obtuse, her speech was very indistinct, and her memory was lost. She at last seemed to lose the power of every voluntary muscle, so that she could neither move her legs nor arms, nor raise her head. Finally, she had convulsions and apoplectic attacks, and died suddenly about the end of the third month of her ill- ness, that is, less than a month from the commencement of the symptoms in the head. In the posterior lobe of the right he- misphere of the brain, behind the lateral ventricle, a portion, the size of a large walnut, (fructus regise juglandis,) was in a state of high inflammation; the membranes adhered to the surface of the brain in several places ; where this did not oc- cur, there was serous effusion under the arachnoid. There was no fluid in the ventricles ; there were hydatids in the choroid plexus, which were most numerous on the right side. The spleen was much enlarged; and extravasated blood, to the amount of several pounds, was found in the abdomen ; it ' Treutlen Auctariuin ad Helminthologiam Humani Corporai, p. I 12 90 INFLAMMATION OF THE HEMISPHERES. was contained partly in the cavity of the omentum, partly be- tween the laminae of the mesocolon, and partly under the pe- ritonseal coat of the descending colon. II. The Ramollissement of the cerebral substance does not appear to be characterized by any uniformity of symp- toms. In particular, there does not appear to be any founda- tion for a statement made by some of the French writers, that it is distinguished by tonic contraction of one or more limbs. This symptom occurred in Case XXX. at an early period, and afterwards disappeared. It is also met with in connexion with affections of the membranes, without any disease of the cerebral substance ; and with the encysted abscess ; and it is frequently observed in cases of typhus, where there is much cerebral disturbance, but which terminate favourably. Lalle- mand* remarks, that he had taken up the idea of the rigid con- traction of the limbs being diagnostic of ramollissement, and was very much perplexed when he met with a case in which all the limbs were in a state of the most remarkable relaxation. The cases which terminate by ramollissement seem in ge- neral to be characterized by convulsion, more or less extensive, followed by paralysis and coma, the convulsion ceasing for some time before death, and being succeeded by the coma; but in Case XXX. the convulsion continued with the utmost violence till the very time of death. In Case XXXIV., on the other hand, there was no convulsion, but a sudden attack of palsy, exactly resembling the ordinary attack of hemiplegia from other causes. In the very remarkable Cases, XXXII. and XXXIII., we find ramollissement of very limited extent, as the only morbid appearance, in connexion with symptoms of long standing; both cases being at last rapidly fatal by a sudden attack of convulsion. In some of the subsequent cases, again, we find most extensive destruction of the cerebral sub- stance, without either paralysis or convulsion, and even with- out coma. In one remarkable case to be afterwards describ- ed, namely, the last case under tubercular disease, we shall find destruction of the cerebral substance, to as great an extent perhaps as is upon record; while the patient went to bed in the state of health in which she had been for many months be- fore her death, and was found dead on the morning. We find the same difficulty in attempting to ascertain the * Lallemand, Recherches sur l'Encephale. review of the subject. 91 effect of ramollissement of particular parts of the brain, in pro- ducing symptoms in particular organs. Convulsion on the same side with the disease, and paralysis on the opposite side, appear to be frequent symptoms, but, as we have seen, by no means uniform. In several of the cases, the speech was re- markably affected, but they present no uniformity in the seat of the disease. The recovery of speech in Case XXXIII., was a remarkable occurrence. In a case by Lallemand, in which the upper part of both hemispheres was affected, there was resolution of all the limbs ; and in one in which the ra- mollissement was seated in the tuber annulare, there was squinting, with resolution of all the limbs, and distortion of the head backwards. The same writer describes two cases in which the disease was in the cerebellum. In the one, there were headach, phrensy, convulsive motions, and sudden death; in the other, in which it was in the left lobe, there was loss of speech, with palsy of the right side, and stupor ; it was fa- tal in eight days. III. In the cases which terminate by Suppuration, we find the same diversity of symptoms as in the cases now re- ferred to. The suppuration, we have seen, varies, by being in some cases confined in a distinct encysted abscess, and in others forming an undefined mass of disease, in which puru- lent matter is more or less mixed with cerebral substance in a state of ramollissement. In the latter form of the disease, the symptoms are often exceedingly obscure and undefined, as we see in Cases XXXVI. and XXXVII. In the encysted abscess, they appear to be in general more marked and severe. The course of symptoms in Case XXXIX. was very remarkable. The sudden attack of convulsion, followed by paralysis of one arm, probably occurred in the inflammatory stage, for when the symptoms were relieved by the bloodletting and other remedies, the arm recovered its motion. The convulsion re- turned, and the paralysis along with it, and again subsided; and after several attacks of the same kind, the paralysis be- came permanent. The thigh and leg then went through the same course. In such a case, it appears highly probable, that the convulsion occurs while the inflammatory state is going on, and that the period of suppuration is indicated by the per- manent paralysis. In this case, three abscesses were met with ; but, whether the successive formation of these had any relation to the successive attacks of the disease in the arm and 92 inflammation of the hemispheres. leg, must be matter of conjecture. In a similar ease, related by Bartholinus, the leg was first affected, and afterwards the arm. One abscess only is mentioned, of which it is merely stated that it was on the opposite side. In a case by Schen- kius, there occurred paralysis of the left side, and convulsion of the right; there was a superficial abscess on the right side of the brain. Something similar to this occurred in a case to be afterwards mentioned, (Diseases of Bones,) in which there was paralysis of the left side, with convulsive agitation of the right arm. In a girl aged 5, whose case is described by Dr. Bateman,* an abscess was found in the posterior part of the right hemisphere, inclosed in a fine vascular sac, and contain- ing four ounces of pus. She was first affected with convul- sion of the whole body, which continued for nearly two days; i luring this time, the left side was in a state of rigid extension, and the right was in constant motion ; and when the attack subsided, the left side remained paralytic. She then had headach, squinting, blindness, and repeated convulsion; and died after an illness of fifteen weeks, having been comatose for only one day before death. In some cases of this kind, paralysis has occurred without convulsion, and in others, con- vulsion without paralysis ; but one or other of these affections appears to be a common attendant on the encysted abscess. In a case described by Morgagni, the prominent symptoms were, pain of the left side of the head, delirium, loss of speech, and weakness of the muscles of the left side of the neck; the man died in 14 days, gradually exhausted ; and an abscess was found in the right corpus striatum, which had burst into the ventricle. In a case by Valsalva, in which the disease was in the corpus striatum, the speech was much affected, and one side was paralytic. In another, there were indistinct- ness of speech, and paralysis of the right side, connected with an ulcerated cavity at the base of the brain on the left side. In a third case by the same writer, there were paralysis of the right side, and convulsion of the left, with an ulcerated cavity in the substance of the brain under the choroid plexus of the left side. Many other varieties occur in the symptoms, in re- gard to which it is unnecessary to enter into any lengthened de- tail. In a case by Lallemand there were cramps of the limbs followed by a sudden attack of palsy of the right side. After- three days the affected limbs were seized with convulsions * Edir*. Med. Journal, vol. i. p. 150. review of the subject. 93 which occurred for several days, and ended in fatal coma. Ano- ther case, by the same writer, began with pain in the right side of the head and tremor of the left arm. This was follow- ed by a continued convulsive flexion and extension of the left arm, which after some days passed into palsy. There were then some convulsive motions of the limbs of the right side ; the abscess was in the right side of the brain. In a man, men- tioned by Broussais, an extensive abscess was found in the centre of each hemisphere, without any other symptom than a puculiar dulness of manner, with taciturnity, and at last coma after 37 days. In cases of a more chronic kind, the abscess is often found inclosed in a mass of tubercular matter or indu- rated cerebral substance. These have probably supervened upon chronic disease of the brain, which, after continuing long in an indolent state, has at length passed into suppuration. In a few cases, abscess has been found in the brain without any symptoms which indicated its existence. Morgagni found one in the posterior part of the brain in a man who died of gangrene of the nates, without any symptom in the head. A man, mentioned by Dr. Powel, was received into St. Bartholo- mew's hospital on acount of cough, dyspnoea and bloody ex- pectoration. He died after he had been a month in the hos- pital, having been for some time before his death in a dozing state, with occasional delirium, but without coma, and he had never complained of his head. His lungs Were much diseas- ed, and an abscess the size of a large walnut was found in the substance of the brain, under the anterior part of the corpus callosum.* In the encysted abscess of the cerebellum, the symptoms seem to be less violent than when the disease is in the brain. A very slight convulsion occurred once in Case III. In CAse XLV. the most remarkable symptom was the loss of the power of swallowing. In a case by Plancus, there was pa- ralysis of one side, and it is stated to have been on the same side with the disease.f In Case III., though the disease was in the cerebellum, the principal seat of pain was in the fore- head, and this has been observed in other cases of the same kind. IV. The superficial ulceration of the brain ap- pears to be a rare occurrence, and some of the cases of it pre- sent phenomena of rather an interesting character. A man, * Med. Trans.Coll. of Phys. London, vol. y. t Storia Med. d'una Postema del lobo destro del cervelletto. 94 INFLAMMATION OF THE HEMISPHERES. mentioned by Dr. Powel,* was affected with a convulsive mo- tion of the left side of his body, which very much resembled chorea ; he was free from it during sleep, and had no other complaint. This affection continued five weeks, and then suddenly terminated in palsy of the affected side. Soon af- ter this, his right hand and arm became convulsed, but in a slighter degree ; he then became gradually comatose, and died two months after the commencement of the complaint. On the anterior part of the right hemisphere of the brain, there was a superficial loss of substance from ulceration, two inches in length and as much in breadth ; it presented an irregular excavated appearance, and a thin layer of curdled matter was deposited in it. There was a similar disease, but much less extensive, on the anterior part of the left hemisphere, and there was much fluid in the ventricles. A lady, mentionedby Dr. Thomas Anderson! of Leith, had been for several years liable to headach, Which was most violent at the crown of the head. After she had suffered for a considerable time from this pain, she was seized with a convulsive affection of the left arm and leg. It occurred in paroxysms, attacked her several times every day, and generally continued about half an hour at each time. This complaint became gradually more and more se- vere ; the right side became slightly affected in the same man- ner, and she was afterwards liable to attacks of coma, in which she often lay for 24 hours at a time. She died at last of gra- dual exhaustion. On the upper part of the right hemisphere of the brain, there was a superficial loss of substance from ul- ceration, two and a half inches long, one and a half broad, and nearly an inch in depth. In the bottom of it there were found some thin laminae of a firm brownish matter, with stony con- cretions, some of which broke into sand on the slightest touch. The effect of superficial inflammation of the brain, or its membranes, is well illustrated by another case related by Dr. Anderson, in which the disease took place under his eye. A boy suffered, from an injury of the head, the depression of a considerable portion of the right parietal bone, the depressed portion being forced through the dura mater, and driven in- wards upon the brain. He had paralysis of the left side and the left eye was insensible. The depressed portion being re- moved, the paralysis was greatly diminished, and the eye re- covered a considerable degree of vLion. On the third day * Trans. Coll. Phys. London, vol. v. \ Trans. Roy. REVIEW OF THE SUBJECT. 95 after the operation, the wound in the dura mater was inflamed, with considerable tumefaction; and immediately the left leg and arm became paralysed, the paralysis being accompanied by convulsion; and the left eye also became again insensible. He had frequent convulsion of these parts for several days, the right side not being in the least affected, when, suppura- tion having taken place, all the symptoms subsided. Had the disease occurred without such an outlet as was in this case afforded to the matter, the suppuration, instead of relieving the symptoms, would probably have induced permanent para- lysis and fatal coma. A man, mentioned by Mr. John Bell, suffered, from an injury of the head, extensive extravasation of blood on the surface of the brain, which was removed by repeated applications of the trephine. During the cure, which occupied three months, the left side of the brain suppurated five or six times. The attack of inflammation was always ac- companied by fever, stupor, and difficult deglutition ; but these symptoms were removed by the suppuration. These attacks occurred at various parts of the brain. When they were to- wards the anterior part, he had double vision, which also was removed by the suppuration; when they were towards the posterior part, there was not double vision, but a state of vi- sion in which a candle was seen with a halo around it. Ulceration of the surface of the brain I have seen only in one instance, in a preparation which was shown me by Dr. Macintosh. There were on various parts of the surface of the left hemisphere, spaces of superficial ulceration of various ex- tent, with ragged edges, and sensible loss of substance. The affection occurred in a child of 18 months, and was complicat- ed with effusion in the ventricles, and ramollissement. The pia mater and the arachnoid were destroyed at the ulcerated spots; and the pia mater in other places was studded with minute tubercles. The symptoms were not to be distinguish- ed from those of hydrocephalus in its ordinary form. There were also numerous granular tubercles in the lungs, V. THE INFLAMMATION OF THE -CEREBRAL SUBSTANCE occurs in a chronic form, in which the symptoms may continue for months, and the disease then prove fatal by sup- puration, or without having suppurated. In Cases XXVII. and XXVIII. we have remarkable examples of this form of the dis- ease proving fatal without suppuration. In Case XXVII. we can have little doubt that the disease had existed in the first 96 INFLAMMATION OF THE HEMISPHERES. attack, and, after a protracted illness, had been removed or in a great measure subdued. It then took place again, and was fatal with loss of speech, palsy, and coma; yet after all, it had not advanced beyond the state of simple inflammation. The progress of this more chronic form of the disease seems to dif- fer considerably from the other modifications of it. We have seen that it may continue for a considerable time in a state of simple inflammation, and in that state may be fatal with all the symptoms of perfect apoplexy. It may also, after conti- nuing for some time in this state, pass into ramollissement or suppuration ; but it appeares, that in some cases it terminates by induration of the part of the brain which has been the seat of it. A degree of this occurred in Dr. Hay's case, and it appears probable that, as the induration advances, the in- flammatory appearance subsides; the part is then left in a state of simple induration, and at a more advanced period may pass into unhealthy suppuration. This state of disease may either affect a considerable portion of the brain, from the sur- face downwards, or may be confined to a small circumscribed portion in the substance of the hemisphere. In this case, the affected portion appears, in some instances, to be afterwards sur- rounded by a cyst, and this appearance has been called a tumour in the brain. It is probable that it is merely a part of the cere- bral substance in a state of low scrofulous inflammation; that in its early stage, it is a disease which may be cured; and that the formation around it of a cyst of coagulable lymph, or its termination by induration of the part, are the points in its progress which give it the character of organic or hopeless disease. In either of these states it may be fatal after pro- tracted symptoms, or it may terminate by suppuration. This affection, in its first stage, was observed by Burserius in the anterior part of the right hemisphere, in a man who died after an illness of four months; he had been affected with constant pain of the head near the vertex, fever, paralysis of the left side, and convulsive affections which occurred at intervals. Fantonus found a similar disease in the corpus callosum, in a man who had been long affected with epileptic paroxysms, and at last died comatose and convulsed. In the state of suppuration, Burserius found one the size of a pigeon's egg in the outer part of the right hemisphere under the squamous suture, in a man who had been affected for several months with intense headach, and convulsive tremors of the whole body, which were most severe on the left side. He found Review 6f fliE subject. 97 artdther in the posterior part of trie brdiff near the tefitoriurh, in a wdnfialfi who h'ald been ill for several months #ith severe headach without fever: the" pain was so hrterise as almost en- tirely td deprive her 6f sleep, and she seems to have been gradually worn out by the severity of it without any other fe- markaMfe symptom1. This form of chronic ir/ffarrirrfatiori of a small part of the brain1 is? a! disease of much interest. The symptoms may go on for several months, so as to assume the Character of organic disease; they maty remit,' so as to resemble periodical head- ach; the disease may be fatal with symptoms resembling apoplexy; 6r it may pass into permanent induration of the part afFected; of, after it has appeared to resist all our reme- dies, it may gradually subside. This1 agrees exactly with the course o'f chrbnie or scrofulous inflammation, as we observe it in external parts. We see it in the eye, iri the lymphatic glands, in th£ testicle-, in the mamma, and in the cellular tex- ture. It .takes place rapidly, producing enlargement of the parts,1 and derangement of the functions; it may continue sta- tionary for a Considerable time ; it may trieri terminate by un- healthy suppuration or" ulceratioriy or by permanent induration of the part; or, after resisting for a long time all our remedies, it may gradually subside,with'oiit leaving any permanent chiange in the organization of the part. I think there is little doubt that something of this kind takes place in the'brain, and if thte doctrine be admitted', the practical application 6f it will be, that we shall be less disposed than we usually are, to con- sider such cases as depending upon organic disease, and con- sequently not the objects of active treatment. The' progress of this interesting affection' is well illustrated by Case XXVH., and there are others on record which show it under some varieties in the symptoms. A gentleiriari, men- tioned by Dr. Powell, was affected with severe headach, which occurred in paroxysms': during the paroxysms,' which often cbrttiriued for several hburs', he had double vision, mental de- pression,' and at one time muscular tWitehes arid riiimbness of the l?ft sid& The rjiilse was variable', being sometimes & little frequent, and' sometimes rather below' the natural stand- ard. By large and repeat&d bloodletting, &c., he was'much relieved, but, after a short interval of relief, the complaint re- turned with £reat violence, arid his vision remained perma- nently dotible. After several aggravatioriS arid remissions or this kitidt Hi* had, at the' erid of three weeks, an interval of 13 98 INFLAMMATION OF THE HEMISPHERES. ease for more than a fortnight. The pain then returned with violence, and was accompanied with spasmodic affections of the muscles of the neck. He then derived temporary relief from narcotics, and, soon after this, the complaint assumed so much of a periodical character that it was treated by bark; the pulse at this time was natural. Under this treatment the paroxysms became rather less severe, but not less frequent; and they were attended occasionally by convulsive motions, which chiefly affected the right side. The paroxysms occur- red at very uncertain intervals. They sometimes consisted of pain only, and sometimes of pain accompanied by the convul- sive motions. He died suddenly in a convulsive attack, two months after the commencement of the complaint; for some time he had been considered as better, and had sat up for two hours on the day preceding the night on which he died. The anterior part of the right hemisphere was found much changed in its structure and indurated, so that it is described as a tu- mour. When the dura mater was first removed, the part thus affected appeared to rise higher than the neighbouring parts, and the cerebral substance surrounding it was very soft. The morbid condition here described is probably a different stage of the disease which-occurred in Cases XXVII. and XXVIII.; and there was a considerable similarity in the symptoms to the first attack in Case XXVII. The affection may likewise pass into a still more chronic state of induration, in which it may be protracted for a greater length of time, but producing urgent symptoms; and may at last be fatal by suppuration, or without having suppurated; or, if it be seated in the superficial parts of the brain, it may terminate by the ulceration of the surface formerly referred to. A man, mentioned by Dr. Anderson, received a violent blow on the back of his head, from the boom of a ship, which fell upon him as he was stooping under it. After sometime he had pain in the part, which became gradually more severe, and, after 18 months, brought on convulsive paroxysms of both upper and lower extremities, the violence of which put an end to his life, after he had suffered from them for several months. Both hemispheres of the brain at the posterior part were found inflamed and much hardened. The diseased parts adhered closely to the dura mater, and to the falx ; and the dura ma- ter at that part was thickened and indurated. A man aged 45, mentioned by the same writer, had been liable for several years to convulsive paroxysms resembling epilepsy, but with REVIEW OF THE SUBJECT. 99 this peculiarity, that the convulsion was confined to the right arm and leg. The attacks occurred at irregular intervals, generally once in three or four weeks, and were succeeded by stupor which continued about half an hour. Without any change in the complaint he Was killed by an injury of the head. A portion of the left hemisphere of the brain was found indu- rated, and closely adhering to the dura mater, which at that place was much thickened and hardened. Extravasated blood was found in another part of the head, which appeared to have been the effect of the injury, and the immediate cause of death. In a man aged 35, who had suffered for several months from violent pain in the forehead with epileptic paroxysms, Mor- gagni found the anterior part of the right hemisphere of the brain indurated, and adhering to the dura mater. Baader re- lates the case of a man aged 40, who became suddenly epi- leptic, with pain at a particular part of the left side of the head. There was extensive sensibility of the surface of the left hand and arm, so that the slightest breath of cold air upon them brought on convulsive twitches. After an illness of five years he died rather suddenly. At the part which had been the seat of pain, there was superficial induration of a portion of the brain, and under the indurated part there was an abscess the size of an egg. From the imperfect view now given of this subject, I think it will appear, that the inflammation of the cerebral substance is an affection deserving accurate investigation. There is every reason to believe, that it exists in various degrees of activity; that in the most active form it advances speedily to ramollisse- ment or suppuration; but that it also exists in a chronic form, in which its progress is very slow, so that it may produce ur- gent symptoms for a considerable length of time, without having advanced beyond that stage in which there is a chance of recovery. This latter form we have seen reason to believe may afterwards pass into suppuration, or may terminate by in- duration of the cerebral substance, and may thus assume the characters of organic disease. The disease may affect any part of the brain, and often appears to commence in a very small portion of it, and to extend gradually over a larger por- tion. It appears to be in cases of this kind that we chiefly meet with some singular examples of gradual paralysis, be- ginning perhaps in a very slight degree, or in a single muscle, and advancing very gradually to more perfect and more ex- tensive palsy. A small part of the brain in such cases is pro- 100 INFLAMMATION OF THE HEMISPHERES. bably undergoing this low state of inflammation, gradually gaining ground, and at length^ terminating either by fatal coma or permanent paralysis. In the'palsy conneqted with these inflammatory aflections, there is sometimes, especially in the early stages, violent pain in the affected limbs. In some cases, again, the loss of power is accompanied by total loss, of feeling ; in others, the feeljng remains entire ; and some remarkable examples, are met wifli, in which, the feeling is morbidly increased,. A) case of thi,s kind has been already referred to ; another is menti,p4?ed ty Lallemand. In this case there had been,' after a blow on the head, headach, impaired intellect, and weakness of the limbs. Six weeks after, there was a sudden attack of, loss, of speech, with palsy of the right sjde, and increased sensibility of the parts, so that a touch was painful. Ten days after this, there was an attack of palsy of the left side, with fatal coma. There was an appearance of inflammation and extensive ramollisse- ment of* the cerebral substance of the left side, and on the right side, extravasation of blood, which had' obviously been the origin of the, fatal attack. The disease occurs in the cerebellum in tb^e same chro- nic form which has now been referred, to in regard to the brain ; it in some cases exhibits nearly the same symptoms, and in others the symptoms are extremely obscure. A man, mentioned by Mr. Douglas, had been for three months affect- ed with pain in the forehead, which generally obliged, him to sit with his head leaning forward ;. he had bad appetite and disturbed sleep, but no other symptom. He died suddenly in an attack resembling syncope, haying been for a day much better, with good appetite and quiet sleep. An encysted ab- scess was found in the middle of the cerebellum, and a rup- ture of the left lateral sinus, which probably was the immedi- ate cause of death'* A man, mentioned by Serres,t after a blow on the back and lateral part of the head, which stunned him at the time, had certain unsteadiness in walking, which made him always anxious to take the arm of a friend ; and he had a delicacy of his head, which made him much affected by a small quantity of wine. This continued about eighteen months, when he became sad and irritable, with trembling of the limbs. Soon after, the left leg became paralytic, and the arm * Edjn. Med.

After the inser- tion of a seton in the neck, the arm recovered, and, three months after this, t^e patient died with fever, delirium, and an affection of the bowels. There was disease in the right lobe of the cerebellum, with an abscess and extensive softening,— In another man, mentioned, by the same writer, who died in fprty days, there was palsy of the right leg with wasting of the limb, but without loss of sensi^jlity, the arm being little if at all affected. There was ramollisement of the left lobe of the cerebellum, occupying chiefly the centre of the left pe- duncle. SECTION VI. INFLAMMATION 0# THE CENTRAL PARTJS OF THE B.RA.IN,-- THE CORPUS CALLOSUM, SEPTUM LUCIDUM, FORNIX, AND THE MEMBRANE LININ^ THE VENTRICLES. The morbid conditions which, I mean to consider under this head, embrace the various forms of disease which have usually been included under the term acute hydrocephalus. Jn venturing to refer; them, to, a place in the general arrangement of the inflammatory affections of the brain, I may perhaps be considered as advancing too rapidly to a conclusion in regard to the pathology of this important class of diseases. But from all that I have observed of the affections themselves, andftpm the analogy of the corresponding diseases in other parte of the brain, I have now very little hesitation in arranging them in this manlier. I shall state the grounds which have induced me to take this view of the subject, and, confining myself in a great measure to a faithful relation of facts, shall merely pro- pose the inquiry as one of much interest for farther observa- tion. The disease seems to present itself under two different forms. In the one, the inflammation, appears to be seated in the membrane lining the ventricles ; in the other, in the white matter forming the fornix, septum lucidnm, and corpus callo- sum. In the former case, we find, the ventricles filled with a turbid or milky fluid, sometimes containing shreds of coagula- 102 INFLAMMATION OF THE CENTRAL PARTS. ble lymph, and sometimes having entirely the characters of purulent matter. These appearances are often combined with a deposition of flocculent matter or false membrane on the surface of the choroid plexus, or on the inner surface of the membrane lining the ventricles, and sometimes with ramollis- sement of the cerebral matter immediately surrounding them. In the latter case, the affection presents itself in the form of ramollissement or white pulpy degeneration of the parts af- fected. The septum lucidum is found perforated by a ragged, irregular opening, from the softened portion having fallen out. The fornix has lost its consistence in the same manner ; and either has lost its figure, by having fallen down into a soft, ir- regular, pulpy mass, or, retaining in some degree its figure, while it is not disturbed, falls asunder when the most gentle attempt is made to raise it. The lower part of the corpus cal- losum is often affected, though, I think, more rarely than the other parts ; and there is frequently a similar degeneration of the cerebral matter immediately surrounding the ventricles.— It is generally, but not always accompanied by effusion in the ventricles of limpid fluid. The substance which is the pro- duct of the disease, is of a pure white colour, without fetor, and without the slightest resemblance to purulent matter. It sometimes shows a slightly fibrous texture, but in general is entirely of a soft pulpy consistence without any cohesion of parts. From all that I have observed of this affection, I have no hesitation in considering it as the termination of inflammation in these particular parts. It is an appearance of very frequent occurrence, and seems to hold an important place in the pa- thology of the brain, and particularly in the pathology of acute hydrocephalus. A most interesting point in the history of it is, that it may be fatal without effusion, and without any other morbid appearance, though with all the symptoms which are usually considered as indicating acute hydrocephalus.— The first case of it which I shall present seems to establish the inflammatory origin of the affection, by showing the per- foration of the septum lucidum, surrounded by a ring of in- flammation ; I shall then show it as the only morbid appear- ance in cases which were fatal with the usual symptoms of acute disease in the brain ; and finally, shall submit a selec- rion of cases, showing its connection with serous effusion in the various forms of acute hydrocephalus. In regard to the pathology of this affection, I may also refer to the facts for- INFLAMMATION OF THE CENTRAL PARTS. 103 naerly adduced with respect to the ramollissement in other parts of the brain. Some of them seem to furnish the most sa- tisfactory evidence of the inflammatory origin of this appear- ance, by enabling us to trace, in the same mass, one part in a state of inflammation, and another in a state of ramollisement, and the one distinctly passing into the other. I shall begin this part of the subject by an example of an affection, which seems to be rare,—inflammation confined to the membrane lining the ventricles. § I.—Inflammation of the membrane lining the ven- tricles. Case XLVI.—A child aged 10 months, (January, 1819,) had fever, starting and vomiting; tongue white ; bowels ob- stinate. After a week, the symptoms abated ; his sleep be- came calm, and he was at times playful; but the vomiting continued, with frequent pulse. In this manner, he continu- ed without any remarkable change in the symptoms for nine or ten days; he then became affected with squinting and blindness, and very rapid pulse, and the vomiting continued; he died three days after the occurrence of these symptoms, and death was preceded by a slight convulsion. Inspection.—The ventricles were distended with six ounces of fluid, which was turbid, and contained in itflakes of yellow coagulable lymph. The lining membrane of the ventricles was thickened, and was easily separated by dissection: its inner surface was covered by a thick coating of soft, yellow, adventitious membrane. The septum lucidum appeared to be thickened, and the pineal gland was distended with a greenish fluid. On the posterior part of the cerebellum, the arachnoid, to the extent of a crown piece, was thickened and covered by adventitious membrane ; betwixt it and the pia mater at this place, there,was some deposition of puriform matter. A ease considerably similar to this in the morbid appear- ances, is related by Golis,* though the progress was much more rapid, and the symptoms were more violent. A child aged 14 months, after a restless night, was seized with violent fever and general convulsion, which subsided after topical bleeding, but sood returned with great violence, accompanied * Golis on Hydrocephalus Acutus, Case II. 104 INFLAMMATION OF THE CENTRAL PARTS. by spinal cramps, hemiplegia^ blindness, dilated pupil, and distortion of the face ; he died the same night, about thirteen hours after the attack. The ventricles contained three bunces of turbid fluid ; the inner surface of the ventricles and the sur- face of the choroid plexus were cbvered by adventitious mem- brane ; and a similar deposition was found on the corpus cal- losum, and on the convolutions' of the brain. The same ap- pearance is mentioned by this author in several other cases.— Inflammation must have existed in the same part in a case formerly described (Case XV.,) in which, along with exten- sive meningitis, there was purulent matter filling the ventricles. Morgagni describes a case in an adultj in which the left ven- tricle was found full of purulent matter without any disease of the cerebral substance. The characters of this case were fe- ver, apoplectic symptoms, delirium, convulsions, and palsy of the right side. An interesting case is also mentioned by M. Gendrin, in which both lateral ventricles, and the third ven- tricle, were distended with turbid fluid; their" lining mem- brane thickened', and covered with a thick greenish-yellow matter; and! the fourth ventricle Was full of pus. The patient was a man 41 years of age, who, after complaining for five days of headach, lassitude, and impaired digestion, was seized with fever, with increase of headach and vomiting, followed by drowsiness, delirium, rigidity of the neck and dilated pu- pils, and he died eornatose in' six days'. § II.--THE INFLAMMATORY ORIGIN OF THE RAMOLLISSE- MENT OF THE SEPTUM LUCIDUM. Case XLVII.—A girl aged 6, about two months before her death, had a violent and obstinate diarrhoea, by which she was much emaciated; after three or four weeks it abated considerably, arid for a fortnight she was better. She was then seized with severe pain of the belly, vomiting and head- ach, the bowels being rather obstinate. The pain of the head was violent, and bhiefly referred tb the forehead. The pulse was from 30 to 40 in a minute, and there was a constant con- vulsive motion of the right arm and leg.- Without any re- markable change in the symptoms, she sunk gradually into stupor, and* died after two days of perfect coma, about a fort- night from the commencement of the headach. The convul- sive motion of the right arm and leg continued through the RAMOLLISSEMENT OF THE CENTRAL PARTS. 105 whole course of the disease, and almost to the moment of death. The pulse continued from 30 to 40 in a minute until a very few days before her death, when it rose to 70, and oc- casionally to 80. Inspection.—The ventricles of the brain were distended with colourless fluid. In the septum lucidum, there was a rag- ged, irregular opening, from loss of substance, and the open- ing was surrounded by a ring of inflammation. The inner surface of the ventricles was in a state of high vascularity, and the cerebral substance immediately bounding them, was in some places considerably softened and broken down. In the anterior part of the left hemisphere, a portion of the brain was dark-coloured and firmer than natural, and some small, hard tubercles were imbedded in it. The inner surface of the caput coli and of the ascending colon was of a dark-red co- lour, and large patches were elevated into a dark-red fungus. § III.—Ramollissement of the central parts fatal WITHOUT EFFUSION. Case XLVIII.—A woman aged 30, (18th June, 1816,) was affected with violent pain in the head, which extended across from temple to temple. She was extremely restless, tossing from one side of the bed to the other, owing to the intensity of the pain; eyes slightly suffused, and impatient of light; pupils contracted ; the pulse 60, soft and rather weak; tongue white. She was bled repeatedly, both generally and topically, and used purgatives, «old applications to the head, blistering, &c. For three days she appeared much relieved ; the violent pain was removed, and she complained of pain only when she moved her head ; pulse from 80 to 90. She was quite sensible, but considerably oppressed and inclined to lie without being disturbed. On the 22d, her speech was affected ; she was sensible of it herself, and said that " she felt a difficulty in getting out her words ;" pulse 112. (23d and 24th) Increasing stupor, and at times incoherence, but, when roused, she answered questions distinctly; double vision; made no complaint, but said her head was better. Pulse from 112 to 120. (25th) Increasing stupor. (26th) Complete coma and dilated pupil; pulse 108 and of good strength; died in the night. Inspection.—The fornix and septum lucidum were broken 14 106 RAMOLLISSEMENT OF THE CENTRAL PARTS, down into a soft white pulpy mass. There was no effusion in the ventricles, and no other disease in any part of the brain. Case XLIX.—A man aged 36, a blacksmith, had been for some months affepted with pectoral complaints, which were considered as phthisical. On the 10th of November, 1818, being suddenly told of the death of his daughter, who died of phthisis, he instantly complained of headach ; and, after another day or two, a remarkable change wa* observed in his temper, which became uncommonly fretful and irasci- ble. He still complained of constant headach, which was much increased by motion ; his pulse varied from 70 to 110. In this state he continued for a week, without any alleviation of the headach. In the second week he began to be slightly delirious, with a tendency to stupor, the headach continuing very severe. He became gradually more and more oppressed, and at last comatose ; and, after perfect coma of four days continuance, died on the 27th. His pectoral symptoms had entirely subsided after the commencement of the complaints in his head. I did not see this patient during his life, but was present at the examination of the body. Inspection.—The membranes of the brain were very vas- cular. There was no effusion in the ventricles, beyond the usual quantity. The septum lucidum was much broken down, and a large opening was formed through the centre of it. The fornix was reduced to a soft white mass, which could not be raised. There was no other morbid appearance in any part of the brain. The lungs were extensively tubercular, and in some places suppurated. The two cases now described are the only examples which have occurred to me, of the ramollissement of the septum and fornix being fatal, without any other morbid appearance. The only cases in which I find it taken notice of by other writers are, one by Senn and one by Lallemand. In the case by M. Senn,* the patient was eleven years of age. After some days of fever, with pain of the belly and vomiting, she complained of violent pain in the forehead, which was constant and se- vere for several days ; and, after a day or two, was accom- panied by dilated pupil, and distortion of the eyes upwards. This was followed by delirium and a spasmodic retraction of * Senn, Recherches sur la Meningile Aigue des Enfans, Case VIII. WITH EFFUSION OR ACUTE HYDROCEPHALUS. 107 the head; she died on the eighteenth day of the disease, without perfect coma. The ventricles of the brain contained but a few drops of fluid. There was extensive ramollisse- ment of the corpus callosum, septum lucidum, and fornix, without any change of colour in the parts. The vessels of the membranes were distended with blood ; there was no other morbid appearance in any part of the brain. The patient of M. Lallemand* was a woman of 40 years of age, who died after an ilbaess of about fourteen days ; the principal symp- toms were^ fever with violent delirium, and convulsive move- ments. There was extreme loquacity for some days, after- wards somnolence and contraction of the limbs, with extreme sinking. The brain was found entirely sound, with the ex- ception of the corpus callosum and fornix, which were trans- formed into a species of white pulp. § IV.—Ramollissement of the central parts com BINED WITH SEROUS EFFUSION, CONSTITUTING THE MOST COMMON FORM OF ACUTE HYDROCEPHALUS. Case L.—A boy aged 12, (August, 1818,) had been for several weeks observed to be languid and declining in strength, with some cough and pain in his breast. A fortnight before death, he began to complain of his head, and was then first confined to bed. After a week, when he was first seen by a medical man, he still complained much of his head, was op- pressed, and answered questions slowly and heavily; had some diarrhoea and frequent pulse. The oppression increased, and four days before his death he lost his speech and the power of the right side. This was followed by blindness and perfect coma, and he died about the fourteenth day from the commencement of the affection of the head, the pulse having continued uniformly frequent through the whole course of the disease. Inspection.—All the ventricles were distended with fluid ; the septum and fornix were so completely broken down, that the two lateral ventricles and the third ventricle seemed to form one cavity; there was also an extensive ramollissement of the cerebral substance on the anterior part, so that the ca- * M. Lallemand, Recherches sur l'Encephale, lorne i. p. 184. 108 RAMOLLISSEMENT OF THE CENTRAL PARTS. vity thus formed by the ventricles extended within half an inch of the anterior part of the brain. Case LI.—A boy aged 7, (October, 1818,) had fever, and headach, which was referred chiefly to the back part of the head; and the bowels were obstinate. After six or seven days, the pulse came down to the natural standard. The headach continued without any remarkable symptom till a few hours before his death, when he fell into a general state of tonic spasm of the whole body. He died after continuing in this state two or three hours about the 14th day of the dis- ease. There had been in this case no coma, but he had con- tinued quite sensible till the attack of the convulsive affection. Inspection.—The ventricles were distended with fluid, and there was extensive ramollissement of the septum and fornix, and of the cerebral matter immediately surrounding the ven- tricles. Case LII.—A strong young man, aged 20, (18th Septem- ber, 1814,) was affected with violent headach, extreme rest- lessness and some delirum ; face flushed ; pulse 60. He had been unwell so as to keep the house for a week, but had been only occasionally in bed; the symptoms had been much in- creased for two days ; pulse, on the former days, from 80 to 90. Large and repeated bloodletting, and the other usual reme- dies, were employed with activity. (19th and 20th) No improvement; violent headach, and a good deal of delirium ; pulse from 75 to 80. (21st and 22d) Less delirium; pulse 80. (23d-and 24th) Continued better; pulse from 80 to 84. (25th) A tendency to stupor; began not to know those about him. (27th) Perfect coma, in which he lay for four days, and then died. His pulse had continued from 75 to 84. Inspection.—Much fluid in the ventricles, and a good deal found in the base of the skull. The fornix was broken down into a shapeless mass of white pulpy matter. From similar destruction a large opening had been formed in the septum lucidum, and there was also considerable softening of the ce- rebral matter immediately surrounding the lateral ventricles. There was a deposition of false membrane on the upper sur- face of the cerebellum. ACUTE HYDROCEPHALUS. 109 Case LIII.—A man aged 21, (3d Sept., 1816,) was af- fected with violent headach, impatience of light, and frequent vomiting; had an oppressed look, with a fixed expression of his eyes; pulse 70 and strong ; had been ill six days; and for three days had vomited almost every thing he had taken. After bloodletting and the other usual remedies, his headach was very much relieved, and he was free from vomiting for two days. On the 7th he was free from headach, and his look was natural; but his pulse had fallen to 48, and he had occasionally double vision. On the 9th he was sitting up and dressed ; his pulse 60. He was free from headach ; tongue clean, and he had some appetite, but the double vision was constant. (10th) Vision natural, in other respects as before. (11th) Pulse 96 ; made no complaint, but his look was vacant, and the pupils were dilated; there had been some delirium in the night. (12th) Pulse 96 ; considerable delirium, vision natural. (13th) Increasing stupor. (14th) Perfect coma, pulse 120. Died on the 15th. Inspection.—All the ventricles were distended with fluid. The fornix was broken down to a soft pulpy mass which could not be raised. The other parts of the brain were healthy. Case LIV.—A gentleman aged 21, had been for some time affected with cough and occasional haemoptysis. In the beginning of December, 1823, he began to complain of head- ach ; he was not confined, but, on the contrary, walked in one day a distance of eight or nine miles after the headach began. The headach increased gradually, but he was not confined till about the 7th day. From the 7th to the 14th day, he was confined chiefly to bed, complaining principally of sickness and giddiness, and occasional vomiting. On some days there was headach ; on others, little or none. On Monday the 15th, he was up and dressed for some hours, but had double vision. On the 16th, he was oppressed and much disposed to sleep ; the double vision continued. I saw him for the first time on the 17th ; he was then almost entirely comatose, with squint- ing, the pulse below 60. On the 18th, after free purging, he revived considerably, and answered questions distinctly; squinting and double vision continued, with dilated pupil; he made no complaint of his head. On the 19th, the pulse be- gan to rise ; and there was a good deal of incoherent talking. 110 ACUTE HYDROCEPHALUS. On the 20th, there was constant incoherent talking, with a small rapid pulse, and he died in the night. From the com- mencement of the head symptoms, his pectoral complaints had entirely disappeared. Inspection.—There was partial ramollissement of the septum lucidum and of both the thalami; the ventricles were distend- ed with fluid; the lungs were extensively tubercular, and there were several small cavities containing a bloody fluid. Before leaving this subject, it may be right to add a few cases illustrative of some of the most important varieties in the symptoms, and showing the disease at various ages and under various circumstances. Case LV.—Sudden attacks of coma without previous head- ach—the pupils dilating on the admission of light.—A stout boy aged 6, had been for several days feverish, and complain- ed of pain in his belly. After the operation of laxative medi- cine, his pulse came down to the natural standard; he con- tinued languid and listless, but made no complaint of any un- easiness, and had never been heard to complain of headach. About the 5th or 6th day of his illness, 10th July, 1816, with- out any farther warning, he was found in the morning in a state of perfect coma, speechless, and his pupils much dilated; pulse 120. He continued in this state of perfect coma, with frequent convulsive motions of the left arm and leg, for six days, and then died, his pulse having continued steadily at 120 and upwards. On the 12th and 13th, being the 9th and 10th days of the disease, the pupils, which were partially di- lated, were distinctly observed to dilate farther upon the ad- mission of light. Inspection.—The ventricles contained about four ounees of fluid. There was extensive ramollissement of the septum and fornix, and of the cerebral substance immediately surround- ing the ventricles ; this was most remarkable on the left side. ■Case LVI.— Two distinct periods of coma.—A boy aged 13, (13th June, 1822,) had slight headach, with some vomit- ing and fever. After four days, the headach increased and the pulse fell to 60.—5th day, Coma. He came out of the coma on the following day, and the only prominent symptom was remarkable obstinacy of his bowels, which was only got the better of after two days by repeated doses of croton oil ; ACUTE HYDROCEPHALUS. Ill he then seemed much relieved, made very little complaint of his head, was quite free from stupor, and the pulse was natu- ral. On the following day, he complained rather more of his head, then relapsed into coma, and died on the 12th day after some convulsion. Inspection.—The ventricles were distended with fluid, and there was extensive ramollissement of the fornix and septum, and of the lower part of the corpus callosum. Case LVII.—Hydrocephalus, with Hemiplegia.—A girl aged 3, after being three days languid and complaining of some headach and pain in the bowels, was first confined to bed on the-4th June, 1822. She was oppressed, the pulse 100; there was some vomiting, and she complained of head- ach, which seemed to be referred chiefly to the right side of the head. For a week the usual remedies were employed, and there was little change in the symptoms. On the 13th, complete palsy took place in the left arm and leg, which con- tinued from this time entirely motionless, except at one time when they were moved by convulsion. After this, she fell into a dozing state, with dilated pupil and slow pulse; but complete coma took place only two days before death, which happened on the 22d. Inspection.—The ventricles were distended with fluid. In the substance of the right hemisphere, very near the ventricle, there was a considerable portion in a state of complete ramol- lissement ; and, contiguous to this, anteriorly, there was a long and narrow portion of the cerebral substance in a state of re- markable induration. Case LVIII.—In an adult, with very obscure symptoms, and fatal after the coma had disappeared. A lady aged 30, about the 5th June, 1824, was exposed to cold and fatigue during the flow of the menses, which ceased prematurely. After this, she was for some days observed to be remarkably languid, dull, and depressed. The pulse was natural; she complain- ed of slight headach, but her appearance had excited an ap- prehension rather of aberration of mind than of any bodily complaint; and in this manner the affection went on for 9 or 10 days. I saw her on the 15th ; she was then odd in her manner, abrupt and absent, but quite sensible when spoken to; complained of slight headach ; pulse a little frequent. On the 16th, she was much oppressed, and on the 17th, in a state of 112 ACUTE HYDROCEPHALUS. nearly perfect coma, which continued on the 18th. On the 19th, after free purging with croton oil, she came out of the coma entirely, was quite sensible to every thing, and no alarm- ing symptom remained, except that she sometimes saw objects remarkably distorted, and sometimes double. At other times, her vision was quite natural; the pulse was frequent, and the tongue loaded. In this state she continued for several days ; she then complained again of headach ; there was occasional incoherence; the sight was more indistinct, and the pupil di- lated ; and the pulse was increasing in frequency. The pulse continued to rise, with much incoherent talking, and sinking of strength ; and she died on the 25th without coma. Inspection.—The ventricles were distented with fluid, and there was extensive ramollissement of the septum and fornix. There was no other morbid appearance. Case LIX.—Remarkable remissions and apparent convales- cence. A boy aged 7, (20th October, 1824,) complained of pain in the back of his head, with fever and some vomiting. Topical bleeding, purgatives, &c, were employed, and, after being an object of some anxiety for several days, (a brother having a short time before died of an affection of the brain,) he gradually improved, and, on the 27th and 28th, he was free from complaint, and going about the house apparently in his usual health. On the evening of the 28th, he was suddenly seized with violent convulsion, which returned through the night every two hours, leaving him in the intervals in a state of coma; the pupils dilated, and insensible. On the 29th, he was nearly comatose the whole day, the pulse weak, and va- rying in frequency from 60 to 120. General and topical bleed- ing, purgatives, &c, had been employed. (30th) Became quite sensible ; the eye natural; pulse still frequent. He com- plained slightly of the back of his head, for which more topi- cal bleeding was employed, with purgatives. He then im- proved progressively; the pulse was from 80 to 90; and he was free from complaint, except that the bowels were torpid and the stools unhealthy, and that the pupil was large, and contracted slowly on the admission of light. In this state he continued several days, when the convulsion returned with greater severity five or six times, leaving him as before in a state of coma. From this he recovered partially, but sunk gradually, and died in a few days. For two or three days be- ACUTE HYDROCEPHALUS. 113 fore his death, there appeared to be considerable palsy of the left arm and leg. Inspection.—There was extensive effusion in the yentricles, and extensive ramollissement of the fornix. The right lamina of the septum lucidum was in a state of ramollissement at the anterior part, occupying about the half of it; and the left la- mina was in the same condition in its posterior half; there was no perforation. An interesting modification of this affection is that which supervenes upon other diseases, chiefly of a chronic nature, especially affections of the lungs ; and the remarkable circum- stance in these cases is, that the pectoral symptoms generally cease after the commencement of the symptoms in the head. The three following cases will illustrate the principal forms of this affection. Case LX.—An ingenious artist, aged 30, had been affect- ed for some years with cough and expectoration, which was decidedly purulent; but, though much confined to the house, he was able to attend to his business as an engraver. In the beginning of June, 1819, being one day considerably agitated in the discussion of some business in which he, thought him- self ill used, he felt uneasiness in his head, and soon after his speech became very indistinct. The headach increased, and was chiefly felt in the left side and back of the head, and the pain extended to the upper part of the neck ; his speech con- tinued much impaired ; the pulse from 90 to 96. The usual remedies were employed, with partial and temporary benefit. The case was drawn out to nearly three weeks, without any remarkable change in the symptoms. He sunk gradually into coma, and died ; the pectoral complaints having subsided as those in the head advanced. Inspection.—There was extensive effusion in the ventricles of the brain, and complete destruction by ramollissement of the septum lucidum, fornix, part of the corpus callosum, and the cerebral matter bounding the ventricles. In the upper part of each lobe of the lungs, there was a portion of the size of a small orange in a state of great induration, and internal- ly presenting an irregular mass of ulceration; the lungs in other respects were' healthy. Case LXI.—A gentleman aged 24, had been affected for 15 114 RAMOLLISSEMENT of the central parts, about eight months with cough and expectoration. In Au- gust, 1824, he was seized with copious haemoptysis, and had frequent attacks of it during August and September. In Oc- tober this ceased, but the cough continued severe, with copi- ous purulent expectoration and great loss of flesh and strength. In the end of November, he began to complain of headach, which continued from this time to affect him considerably, ac- companied by occasional vomiting; the cough and expecto- ration continuing. From this time he became much less able for exertion than formerly, but no remarkable change was ob- served in the symptoms till the first week of January, when one evening he suddenly lost his speech. He recovered it again next day, but complained of headach, and was listless and languid. On the third day he lost his speech again, and recovered it on the 4th. He lost it again on the 5th, and on the 6th recovered it. From this time his speech continued tolerably distinct, but he gradually sunk into a kind of fatuous state, with occasional paroxyms of high delirium, and repeat- ed convulsive affections of the face and upper extremities. The pulse continued nearly natural; the expression of the countenance was remarkably vacant, and he still frequently complained of his head. He thus gradually sunk into coma, and died in about three weeks from the time when he first lost his speech. From the commencement of this attack his cough ceased entirely, until a few days before his death, when it re- turned in a very slight degree. Inspection.—There was considerable effusion in the ven- tricles, and extensive ramollissement of the septum, fornix, and adjoining parts. Along the base of the brain, there was an extensive deposition of yellow adventitious membrane of considerable thickness. There was extensive tubercular dis- ease in both lobes of the lungs, with numerous large vomicae. Case LXII.—A lady aged 28, had been for some months in winter 1823-24 affected with cough, considerable expecto- ration, some uneasiness in the chest, great loss of flesh and strength, and quick pulse. She came to Edinburgh about the 20th of May, 1824; the cough then subsided remarkably, which was ascribed by her friends to the change of air, and in a few days it entirely ceased. She then continued pretty well till about the 27th,when she began to complain of headach, and for the next three days she was dull and silent, seemed absent and low-spirited, and complained that her sight was dim. She was partly in bed, but her pulse was natural. On 4 OCCURRING IN PHTHISICAL CASES. 115 the 31st, the pulse began to rise, and there was considerable incoherent talking. I saw her for the first time on the fol- lowing day, the 1st of June ; her look was then absent, va- cant, and anxious, and she talked a little incoherently, but understood what was said to her; there was double vision and slight squinting, the pulse very frequent. (2d) Sight seemed much impaired, pupil dilated, much wild talking at times, but she knew those about her, and answered distinctly when spoken to; pulse rapid and feeble, died in the night without coma. Inspection.—The ventricles of the brain were distended with a large quantity of fluid, and there was extensive ramo- lissement of the septum, and all the central parts. About and above the optic nerves, there was a considerable deposition of coagulable lymph in a firm, dense, opaque state. The lungs were tolerably healthy in their structure, but there were marks of extensive chronic inflammation of the pleura on the right side, with considerable deposition of coagulable lymph. It is unnecessary to multiply cases which present no parti- cular variety in the phenomena; those which have been de- scribed will probably seem sufficient to illustrate the principal forms of this affection, and at the same time to exemplify some of the most remarkable varieties in the symptoms. From a fair and candid review of the whole subject, I think we can have little hesitation in concluding, that this is the ordinary form of the disease, which is commonly called acute hydrocephalus; that it is originally an inflammatory affection, chiefly seated in the substance of the central parts of the brain ; that it generally terminates by ramollissement of these parts, combined with serous effusion in the ventricles ; and that it may be fatal by the ramollissement alone, even of small extent, but with all the symptoms which are commonly con- sidered as characteristic of acute hydrocephalus. The cases likewise exemplify various important varieties in the symp- toms. We have seen in some of them, perfect coma of long continuance without any effusion ; and in others extensive effusion without any degree of coma. We have seen again the coma entirely removed, and yet the disease go on to its fatal termination. We have seen every variety in the state of the pulse, of the vision, and of the intellectual functions ; and we have seen the disease run its course without any com- plaint of pain or any symptom indicative of danger, until the 116 CASES OF SIMPLE EFFUSION. patient was unexpectedly found in a state of profound coma. These and many other varieties, presented by the cases which have been described, shew us the danger of being guided by system in our diagnosis of affections of the brain, and the ne- cessity that there still is for extensive and careful observation of facts in regard to this class of diseases. The form of the disease which has now been described, I conceive to be the more common modification of acute hy- drocephalus ; but it is to be kept in mind that serous effusion takes place in the brain under other forms. In some of these it is connected with inflammatory affections of other parts of the brain or of the membranes; but it may take place with- out exhibiting any other appearance, excepting the simple offusion. As a contrast to the cases now described, I shall add two examples of hydrocephalus which presented simply serous effusion in the ventricles, without any other morbid appearance in the brain ; and with regard to these two cases, I think it right to add, that they are the only examples of this kind which I find among my notes of cases of idiopathic hydrocephalus. It will be seen that they exhibit the disease in its most insidious and chronic form, and present a remark- able contrast to the active symptoms in some of the former cases. § V.—Cases of simple effusion. Case LXIII.—A boy aged 9, was affected with slight headach, foul tongue, bad appetite, and disturbed sleep ; pulse from 96 to 100. The first week of his illness was passed with these slight symptoms; he was one day better and an- other rather worse; his headach was sometimes gone for a great part of the day, and never severe. Towards the end of the second week there appeared to be a want of correspond- ence in the symptoms, the headach being greater and more permanent than accorded with the degree of fever; but even on the 13th and 14th days, the complaint had still much the appearance of the mildest form of continued fever, and was considered in that light by a physician of the first eminence. During the second week, however, the headach had become more severe, while the other febrile symptoms had been di- minishing. On the 15th day the pulse sunk rather suddenly to 70; and the headach was increased. On the 17th there CASES OF SIMPLE EFFUSION. 117 was coma, with some squinting; the pulse below the natural standard. On the 18th the pulse began to rise, and the coma was diminished. On the 19th and 20th he was distinct and intelligent, tongue clean, some appetite, pulse 96. On the fol- lowing day his appearance was less favourable; he then sunk gradually into coma, with squinting, and died about the 30th day of the disease. The pulse had risen to 120, and in the last week there had been some slight return of convulsion. Inspection.—All the ventricles of the brain were found dis- tended with clear serous fluid ; there was no other morbid appearance, except considerable turgidity of vessels on the surface of the brain. Case LXIV.—A gentleman aged 24, was affected with slight headach, and unusual listlessness and inactivity. He ascribed the complaint to cold, and for the first week conti- nued to attend to his business. In the second week he had considerable headach, shivering, debility, bad appetite, foul tongue, and disturbed sleep, pulse about 112. Towards the end of this week, his friends observed once or twice a slight and peculiar forgetfulness. In the third week his pulse came down rapidly to 72 ; his tongue became clean; he made little or no complaint of his head, but there was occasionally a de- gree of incoherence, which was slight and transient, and a singular forgetfulness on particular subjects, which was ob- served by his friends, but did not appear in his intercourse with his medical attendants. The pulse continued slow for two days, and then rose rapidly to 130, with increase of de- lirium. After a few days more, the delirium again subsided, and great hopes were entertained of his recovery; but the delirium soon returned, and was rapidly followed by blindness, coma, and death. He died about the middle of the fourth week of his illness. I did not see this patient daring his life, but was present at the examination of the body. Inspection.—All the ventricles of the brain were found dis- tended with clear serous fluid, without any other morbid ap- pearance. The pathology of cases of this kind is perhaps more obscure, than that of the cases formerly referred to ; but that, in these cases likewise, the effusion arises from a low degree of inflammatory action in the brain, is probable from the fact, that similar appearances are occasionally met with in those in- 118 GENERAL REVIEW OF THE SUBJECT. stances in which the disease supervenes upon injuries of the head, as in the following cases. Case LXV.—A man aged 40, of a scrofulous habit, was standing on a cart at Leith races, when the horse moving for- ward, he lost his balance and fell out of the cart, striking his head upon the sand. He felt at the time no inconvenience, and for a week attended to his business, but complained fre- quently of headach. He was then confined to the house from increase of headach, with vomiting, and slight fever; after a few days, he became oppressed, then comatose, and died at the end of the second week. Inspection.—All the ventricles of the brain were found dis- tended with serous fluid, without any other morbid appear- ance. Case LXVI.—A girl aged 13, fell from a swing, and struck her head with some violence on the ground. From that time she complained of headach, but was not confined, nor was her health otherwise affected, until six weeks after the accident, when her headach increased, and was accompa- nied by vomiting and frequent pulse. The vomiting soon subsided, but was followed by slight delirium, and this by coma. She lay in a state of coma for five or six days, and then died, two months after the fall. Inspection.—All the ventricles of the brain were found dis- tended with serous fluid, without any other morbid appear- ance. A general review of this important subject seems to lead to some results of much practical importance in the pathology of affections of the brain, particularly in regard to that class of them which terminate by effusion. There are many facts on record, which shew us the presence of fluid in the brain in large quantity, without any alarming symptom having resulted from it. Morgagni found eight ounces in a man who died suddenly of suffocation in an advanced stage of pneumonia ; and Dr. Heberden found the same quantity in a man who died suddenly, after being weakened by a febrile attack, without any symptom of an affection of the brain. It is therefore not the mere presence of a certain quantity of fluid in the brain, that gives rise to the symptoms of hydrocephalus, and on the other hand, we have seen a disease go through all the usual symp- toms of hydrocephalus, and terminate fatally without any effu- GENERAL REVIEW OF THE SUBJECT. 119 sion. The fair conclusion from these facts appears to be, that the prominent symptoms in these cases are not the re- sult of the effusion, but of that disease of the brain of which the effusion is one of the terminations. From a variety of facts which have been adduced, there seems little reason to doubt that this disease is of an inflammatory nature. If these conclusions shall be considered as well founded, it will follow, that our practice ought to be directed principally to subduing the inflammation at its earliest period, and pre- venting it from passing into effusion, and particularly from passing into ramollissement, which we have seen to be a fatal termination of the disease even though of small extent and without any effusion. This termination, I think, we have every reason to consider as the result most to be dreaded in this class of the inflammatory diseases of the brain; for in regard to the mere effusion, were the parts otherwise in a healthy state, there does not seem to be any very satisfactory reason for considering it as a hopeless affection. In other words, I mean to submit, that-we have no good reason for doubting the possibility of serous fluid being absorbed from the ventricles of the brain. We are warranted in this sup- position, both by the analogy of other serous cavities, and by what we actually see take place in the brain itself. In the other serous cavities, We have every reason to believe, that there is constantly going on an obsorption of the old fluid, and a deposition of new fluid in its place; and we see them in a state of disease, relieve themselves by an increased ab- sorption from an excess of fluid which has been deposited. The ventricles of the brain are unquestionably to be consider- ed as serous cavities ; and there seems to be no good reason for considering them as differing in their functions from the other cavities of the same kind, whatever the particular appa- ratus may be by which the function is carried on. In regard to the actual existence of absorption in the brain, we have the most satisfactory proof, in the gradual disappearance of co- agula of blood, both from the surface and from the ventricles, and from the cavities in the substance of the brain. Upon the whole, I think we have sufficient ground for receiving the following conclusions in regard to this class of affections of the head. 1st, That in the ordinary cases of hydrocephalus, the coma and other symptoms attending it are not to be considered as the direct effect of the effusion, but of that morbid condition of the brain of which tlie effusion is the consequence. 120 GENERAL REVIEW OF THE SUBJECT. 2d, That we have no certain mark which we can rely upon as indicating the presence of effusion in the brain. Slowness of the pulse followed by frequency, squinting, double vision, dilated pupil, paralytic symptoms, and perfect coma, we have * seen may exist without any effusion. 3d, That all these symptoms may exist in connexion with a state of the brain, which is active, or simply inflammatory, while the disease is the subject of active treatment, and while by such treatment, adopted with decision at an early period, we have the prospect of arresting its progress in a considera- ble proportion of cases. The ground of prognosis in particu- lar cases depends perhaps in a great measure upon the activity of the symptoms. The more they approach to the character of active inflammation, our prospect of cutting them short will be greater; and the more they partake of the low scrofulous inflammation, it will be the less. In all of them, the period for active practice is short, the irremediable mischief being probably done at an early period of the disease. These principles bear immediately upon the question, Has hydrocephalus been cured? There is no doubt that many cases have recovered, which exhibited all the usual symptoms of it, several examples of which will be mentioned in the se- quel. Such cases have by some been confidently brought forward as examples of hydrocephalus cured, while others have only considered them as remarkable from their singular resemblance to that disease. If the principles now referred to be admitted, we shall see reason to believe, that we have no certain rule by which we can decide upon the presence of effusion in the brain; but that all the symptoms usually attend- ing it exist in connexion with an inflammatory condition of the brain, which, if allowed to go on, would probably lead to effusion, but which, if treated with decision in its early stage, may, in a certain proportion of cases, be treated with success. Whether the fluid can be absorbed, or the disease cured, after effusion has taken place, must remain matter of conjecture; but, from the facts which have been adduced, we have every reason to believe, that in the ordinary cases of hydrocephalus, the removal of the fluid, if it did take place, would in no re- spect improve the situation of the patient,—because there would still remain that deep-seated disease of the central parts of the brain, which accompanies the effusion in so large a proportion of cases, and which we have seen may be fatal without any effusion, yet with all the -usual symptoms of hy- drocephalus. INFLAMMATORY AFFECTIONS OF THE BRAIN. 121 SECTION VII. OF TH*E CAUSES OF THE INFLAMMATORY AFFECTIONS OF THE BRAIN. In a great proportion of the cases of the inflammatory af- fections of the brain, the causes elude our observation; the circumstances under which they most frequently occur, are chiefly the following: I, They often appear in the course of other febrile diseases, as continued fever, scarlatina, measles, &c. One of the most frequent and most severe examples of the disease arising from this source, is an affection which supervenes upon scar- latina, A child recovering from scarlatina, which may have been in a mild form, is seized, perhaps after some exposure to cold, with headach, which after a short time is followed by convulsion, and this by blindness and coma. These symp- toms may have been preceded by the anasarca which frequent- ly supervenes upon scarlatina, and on that account, are apt to be ascribed to sudden effusion in the brain; but the disease is entirely inflammatory, and the patient can be saved only by the most vigorous treatment,—by bloodletting, purgatives, and other similar remedies. Upon this plan, many such cases re- cover; others die and present the usual appearances of the inflammatory affections of the brain; and some of those who have recovered from the affection, have been afterwards liable to epileptic paroxysms. A similar disease occurs in continu- ed fever, especially in the more advanced stages of it. If it has come on gradually and insidiously, it is generally hope- less ; if it be in a more acute form, the patient may frequently be saved by active treatment. In connexion with low and protracted fever, however, a condition frequently occurs, which puts on many characters of the most dangerous affections of the brain, but these pass off when the fever subsi les. A boy between 4 and 5, whom I saw with Dr. Begbie, with much of the character of low fever, had stupor followed by dilated pupil and blindness with some squinting; he then had loss of speech; and after lying completely speechless for,nearly a month gradually recovered. The blindness continued only 16 122 INFLAMMATORY AFFECTIONS OF THE BRAIN. six days : the recovery of his speech was preceded by copious discharge of matter from both his ears. About three months after, he died in the country of a head affection, and tubercu- lar disease was found in the brain, with effusion. In another case, in an adult, which terminated favourably, there was for several days nearly perfect coma, with that spasmodic rigidity of some of the limbs, which the French have considered as characteristic of ramollissement of the brain. II. They may follow injuries, and this perhaps is a more frequent cause of the affections than we are generally aware of, especially in children; the injury being often slight, and the interval very considerable betwixt it and the appearance of any alarming symptoms. I have given two remarkable ex- amples which seem to be referable to this head in cases LXV. and LXVI. III. Suppressed evacuations. One of the most common examples of this is suppression of the menses, which in young women of unsound constitution is very often followed by dan- gerous affections of the brain. Headach, or any symptom in the head occurring under such circumstances, is always to be considered as requiring most minute attention. Case LVIII. affords an interesting example of the disease coming on in this manner, and running its course with a very remarkable train of symptoms. Another affection which seems to be re- ferable to this head, is that effusion in the brain which is apt to supervene upon urinary disorders, particularly on that re- markable affection, the Ischuria Renalis. In this obscure dis- ease, the prominent symptom is a very sudden diminution of the secretion of urine, amounting frequently almost to a com- plete suspension of it. Generally about the third day from the occurrence of this symptom, the patient is found passing into a state of coma, in which after a few days more he dies. The ventricles of the brain are found distended with fluid. In the following singular case, the same symptoms supervened upon another and rather uncommon modification of the dis- ease, namely, Ischuria Ureteralis. Case LXVII.—A gentleman aged 70, (in February, 1816,) complained to me that he could pass no urine ; he made no other complaint, and on introducing a catheter, the bladder was found to be empty. For six days he continued in this CAUSES. 123 state, keeping the house, but complaining of nothing, except once or twice, when closely questioned, of slight uneasiness in his back. On the seventh day, he had slight confusion of thought, and indistinctness of speech. On the 9th, he became comatose, and died on the 13th. On dissection, extensive effusion was found in the ventricles of the brain; the bladder was empty. Both kidneys were distended with urine. Both ureters were completely obstructed by large calculi, the one immediately at its upper extremity, the other about three inches below the kidney. IV. The affections often occur in connexion with disease of a chronic or scrofulous character in other parts of the body. The most frequent example of this is, the brain becoming af- fected in the advanced stages of phthisis. Of this I have giv- en several examples, and I have seen many more, assuming various characters. In one of them, the head symptoms be- gan a month before death, with attacks of loss of speech, which continued only a few minutes at a time, and were ac- companied by a sensation of prickling and numbness of the right side of the face. After the patient had been liable to these attacks for a fortnight, he had headach and slight deli- rium, followed by stupor, which was fatal in another fortnight. In another man, aged 32, who had been ill five weeks with severe pulmonary complaints, the first symptom was double vision, without headach. He complained of dysuria, and his pulse was irregular. In such cases the first disease is not properly to be con- sidered as the cause of the head affection. It merely marks the tendency to inflammation of a chronic or scrofulous cha- racter ; and, in habits so disposed, the affection of the brain may be excited by causes which elude our observation. On the same principle, disease in the brain may appear in con- nexion with disease of any other organ, especially in un- healthy children. In such cases the liver has often been found diseased; and, founded upon this observation, diseased liver has been improperly stated as one of the causes of hydroce- phalus. The same observation perhaps applies to worms and various other affections of the bowels, which in unhealthy children are often found to accompany hydrocephalus, and have sometimes been considered in the relation of a cause. Some of the more acute affections of the bowels, however, seem to be entitled to more attention, though the connexion 124 INFLAMMATORY AFFECTIONS OF THE BRAIN. betwixt them and the affections of the brain is very obscure. In some of them, it perhaps merely arises out of the general fe- brile excitement of the system ; but, in others, there seems to be a connexion distinct from this. One of the most remarka- ble examples is in the inflammation of the mucous membrane of the bowels, which occurs in young children of the age of from eight to twelve months. This affection frequently ter- minates by coma, and the coma appears to be frequently pre- ceded by a remarkable diminution of the secretion of urine. I have elsewhere thrown out a conjecture that this disease, in its relation to the affection of the brain, bears an analogy to ischuria renalis, but perhaps the connexion in both cases is equally obscure. In the dissection of cases of hydrocephalus in young chil- dren, we very often meet with inttis-susceptio in the bowels, and it generally exists in several places. I have repeatedly seen six or seven of them, and in one case fourteen. They appear in general to be quite recent, being free from inflam- mation or thickening of the parts ; and in the cases which oc- curred to me, there did not exist any unusual obstinacy of the bowels. The affection, therefore, is probably to be consider- ed as recent and incidental; or perhaps, as arising out of an inversion or derangement of the peristaltic motion of the bow- els. This may be produced by the affection of the brain in the same manner as, we see urgent vomiting connected with it. In some cases, however, the intus-susceptio appears to have been of longer standing, and to have preceded the affec- tion of the brain. A,girl aged 6 years, mentioned by Dr. Coindet,* had sfvere pain in the belly, vomiting, and con- stipation ; on the fifth day, head symptoms appeared, and she died on the 12th. Much effusion was found in the brain, and there was an extensive intus-susceptio in the ileum, where a portion of intestine, six or seven inches long, was inflamed and thickened. V. Various other causes might be mentioned, such as pas- sions of the mind, stimulating liquors, &c.; but I shall not enter upon these, and shall only add one which is of frequent occurrence, and presents some singular phenomena, namely, exposure to the intense heat of the sun. It appears that in some cases of this kind, the membranes are chiefly affected, and in others the substance of the brain. Sometimes an apo- * Coindet, Memoire sur l'Hydrencephale. TREATMENT OF INFLAMMATORY AFFECTIONS, ETC 125 plectic state is produced, which is fatal in a few hours; but, more frequently, an affection of an inflammatory nature, occa- sionally assuming the character of mania ; and in others, pa- ralytic symptoms occur at an early period followed by coma. The affection of course is chiefly a disease of warm climates, but also occurs in this country, as in the following case, for which I am indebted to Mr. Clarkson, surgeon in Selkirk. Case LXVIII.—A young man aged 15, on the 5th of June, 1818, bathed twice in the river Tweed. After coming out the second time, he lay down on the bank and fell asleep without his hat, exposed to the intense heat of the sun. On awaking, he was speechless, but walked home, and seemed to be otherwise in good health. He was bled and purged, and next day recovered his speech, but lost it again at intervals several times during the three or four following days. *He was for- getful, and his look was dull and heavy; he made little com- plaint, but, when closely questioned, said he had a dull unea- siness in the back part of his head. After a few days more, he had squinting and double vision, with a very obstinate state of bowels, and his pulse was 60. After farther bleeding, &c, the pulse rose to 86, but he sunk gradually into coma, and died on the 30th. Inspection.—The substance of the brain in general seemed highly vascular, and a very considerable extent of it was in a state of ramollisement mixed with suppuration. The ventri- cles were distended with fluid, and the membranes in many places were much thickened. The inner surface of the crani- um was very unequalxt the upper part, frnd one spot, the size of a sixpence, was as thin as writing paper, and transpa- rent. SECTION VIII. OF THE TREATMENT OF THE INFLAMMATORY AFFECTIONS OF THE BRAIN. In the treatment of this important class of diseases the re- medies are few and simple ; but every thing depends upon the 126 INFLAMMATORY AFFECTIONS OF THE BRAIN. use of them being adopted at an early period, and in the most decided manner. Those on which we chiefly rely are blood- letting, general and topical—active purgatives, and cold appli- cations to the head. Benefit is also derived from antimonials, and, in some states of the disease, from the digitalis. The ef- fect of blistering in the early stages is rather ambiguous.— When it is employed, it should perhaps be on the back part of the head and neck; in these situations it is probably more likely to be useful than on the upper part of the head, while it does not interfere with a more powerful remedy, the appli- cation of cold. After the first activity of the disease has been subdued, blisters applied in succession to various parts of the head, and the upper part of the spine, appear to be in many cases extremely useful. Mercury has been strongly recom- mended in that class of cases which terminate by hydrocepha- lus, but its reputation seems to stand upon very doubtful grounds. In many cases, especially during the first or more active stage, the indiscriminate employment of merc#y must be injurious. In the adaptation of the particular remedies to individual cases, we must of course be regulated by the age and habit of the patient, and particularly by the character of the disease in regard to activity. In those cases which as- sume the more acute or active forms, general bloodletting must be used in the most decided manner ; while in the cases which assume a more chronic character, as many of the com- mon cases of hydrocephalus, it has less control over the dis- ease, and is not borne to the same extent. In all the forms of the disease, active purging appears to be the remedy from which we find the most satisfactory results; and although bloodletting is never to be neglected in the earlier stages of the disease, my own experience is, that more recoveries from head affections of the most alarming aspect take place under the use of very strong purging, than under any other mode of treatment. In most of these cases indeed full and repeated bleeding had been previously employed, but without any ap- parent effect in arresting the symptoms. The most convenient medicine for this purpose is the croton oil. In regard to local re- medies, by far the most powerful is the application of cold.— It may be applied in a continued manner by means of a blad- der containing pounded ice mixed with a small quantity of water; but a still more effectual mode of applying it in the more acute cases, is by a stream of cold water directed against the crown of the head, and continued for a considerable time, TREATMENT. 127 until the full effect be produced from it. Applied in this man- ner, it is a remedy of such power, that it requires to be used with much discretion. Under the operation of it, I have seen a strong man thrown, in a very few minutes, into a state ap- proaching to asphyxia, who immediately before had been in the highest state of maniacal excitement, with morbid increase of strength, defeating every attempt of four or five men to re- strain him. The following case shows the immediate effect of it in another modification of the disease. A strong plethoric child, aged five years, after being one day feverish, oppressed and restless, fell rather suddenly into a state of perfect coma. She had been in this state about an hour when I saw her; she lay stretched on her back, motionless and completely in- sensible ; her face flushed and turgid. She was raised into a sitting posture, and, a basin being held under the chin, a stream of cold water was directed against the crown of the head. In a few minutes, or rather seconds, she was com- pletely recovered, and next day was in her usual health. The same remedy I am in the habit of using with the best effect in the convulsive diseases of children ; and it appears to be much more useful in such cases than the warm bath, the in- discriminate employment of which is often decidedly inju- rious. In the preceding observations, I shall perhaps be consider- ed as having attached too little importance to mercury in the treatment of this class of diseases, particularly in the treatment of hydrocephalus ; but in doing so, I have stated simply what is the result of an extensive observation. When mercury was first employed as a remedy for hydrocephalus, it was given with a view to promote the absorption of the effused fluid, which was supposed to constitute the essence of the disease; it is now given to correct the biliary secretion, and the func- tions of the digestive organs, which, according to certain mo- dern doctrines, hold so prominent a place in almost every class of diseases. In affections of the brain, as in all other diseases, it is highly proper that these secretions should be at- tended to, but it is not thus that we are to expect to cure hy- drocephalus ; and I confess the result of my own observation is, that when mercury is useful in affections of the brain, it is chiefly as a purgative. Under the treatment which I have now mentioned, I have seen many cases recover which exhibited all the usual symp- toms of the most dangerous affections of the brain, and even 128 INFLAMMATORY AFFECTIONS OF THE BRAIN. the most advanced stages of them. The cases which thus ter< minate favourably, form, it must be confessed, but a small pro- portion of those which come under the view of a physician of considerable practice ; but they hold out every encouragement to persevere in the treatment of a class of diseases, which, af- ter a certain period of their progress, we are too apt to consi- der as hopeless. I shall conclude this part of the subject by a selection of cases illustrating the favourable termination of the disease in various forms, and under the most unpromising circumstances. Some of these will show the affection arrest- ed in the early or acute stage, while others will illustrate the favourable termination of it with the symptoms which have usually been considered as characteristic of the more ad- vanced period, in which the affection is generally considered as hopeless. When these cases are compared with the fatal cases which have already been described, there will, I think, appear to be every reason for considering them as fair exam- ples of this dangerous affection of the brain. # Case LXIX.—A girl aged 11, had violent headach and vomiting, with great obstinacy of the bowels, and these symp- toms were followed by dilated pupil, and a degree of stupor bordering upon perfect coma ; pulse 130. She had been ill five or six days; purgatives, blistering, and mercury to sali- vation had been employed without benefit. One bleeding from the arm gave an immediate turn to this case ; the headach was relieved, the pulse came down, the vomiting ceased; the bowels were freely acted upon by the medicines which they had formerly resisted; and in a few days she was quite well. Case LXX.—A slender and delicate girl, aged 11, had scarlatina in a favourable form in the beginning of April, 1820. About the 16th, she was so much recovered as to be allowed to go about the house. A few days after this, she was affect- ed with anasarca, for which she took some medicine with par- tial benefit. About the 26th, however, the anasarca had again increased considerably, especially in the face, which was very much swelled. In the following night she had vomiting.— On the 27th, she complained of headach, which increased ra- pidly in violence ; towards the afternoon, she became delirious, the pulse very frequent, about 160. Soon after this she was seized with violent and general convulsion, which recurred TREATMENT. 129 very frequently through the night, leaving her in a state of profound coma. The treatment adopted during the course of these symptoms was repeated general bleeding, to the amount of 28 ounces, followed by topical bleeding, purgatives, anti- monial solution, &c. Towards midnight the convulsions ceas- ed, and some time afterwards she gradually recovered from the coma. On the 28th, she was free from any alarming symp- tom during the early part of the day ; pulse about 108. In the evening she was seized with severe symptoms of pneu- monia, on account of which she was bled during the next 24 hours to the amount of upwards of 30 ounces, besides bleed- ing with leeches and the other usual remedies. In a few days more she was restored to perfect health. • Case LXXI.—A young man aged 16, in the beginning of October, 1823, had cough with severe dyspnoea, for which he was freely bled from the arm with much relief, and on the morning of the 10th, he was considered as convalescent. In the evening of that day he had headach ""and some vomiting. About midnight, having got out of bed to go to stool, he fell down in a state of violent and general convulsion. The con- vulsion returned during the night six or seven times with such violence that one of the attacks continued without intermis- sion for about an hour. The pulse during the night varied from 60 to 120. At first it was found impossible to bleed him on account of the violence of the convulsions, but about 7 in the morning a full bleeding was obtained, though with some difficulty, after which the convulsions ceased, except some slighter attacks during the day, which appeared to be arrest- ed by pouring cold water over his head. During the 11th, he was oppressed, with occasional tremors of the limbs and some vomiting, and he had one or two threatenings of convul- sion ; pulse about 80 and soft: he took repeated doses of ac • tive purgatives with little effect, and on the morning of the 12th he appeared to be sinking into a state of perfect coma; pulse 50. Croton oil was now given, which operated power- fully seven or eight times. He passed a good night, and on the 13th was free from complaint. This very important case was under the care of Dr. Huie. I saw the patient along with him from mid-day of the 11th. Case LXXII.—A gentleman aged 21, was first affected with confusion of thought and very considerable loss of recol- 17 130 INFLAMMATORY AFFECTIONS OF THE BRAIN. lection. He then complained of headach, and after a day or two had double vision, the two objects being placed the one above the other. At this time he was out of bed the greater part of the day, but was restless and confused, and at times incoherent. He was then confined to bed, and had constant headach, much incoherence and oppression, the double vision continuing. The pulse was at first frequent, but fell gradual- ly, and sunk below the natural standard; and the symptoms went through a course exactly similar to that which has been described in many of the fatal cases. As the pulse fell in fre- quency, he became more and more oppressed, until he sunk into a state of stupor, from which he could scarcely be roused so as to answer a question of the most simple kind. The case went on in this manner for eight or ten days, during which time he was treated by repeated general and topical bleeding, cold applications, blistering, &c, without the smallest effect in arresting the progress of the symptoms. The bowels were very obstinate, and large doses of the most active purgatives were given with little effect. He seemed to be on the brink of perfect coma, and the case was considered as desperate, when he began to take the croton oil, in full doses, repeated every two or three hours. In a few hours, he was purged very actively nine or ten times ; the same evening he was re- lieved from every alarming symptom, and in a few days was free from the complaint. Case LXXIII.—A girl aged 2 years and 3 months, previ- ously very strong and healthy, had recently recovered from measles, when about the 7th July, 1821, she suddenly lost the power of both her lower extremities. She continued without any improvement, but without any further symptom, till the beginning of August, when she became affected with squint- ing and drowsiness, and her countenance was expressive of fatuity. On the 7th, she was seized with smart fever, urgent vomiting, and frequent slight convulsions; the face flushed, the pulse strong and frequent. She was treated by Dr. Begbie by bleeding and purgatives ; and on the 8th, she was consi- derably relieved. On the 9th, however, the symptoms return- ed, with stupor bordering upon coma, oppressed breathing, and dilated pupil. The squinting continued, with complete palsy of the lower extremities. Farther bleeding with leech- es was now employed, and active purgatives, followed by blistering on the neck, and under this treatment the more ur- TREATMENT. 131 gent symptoms speedily disappeared. The palsy of the lower extremities then subsided gradually, and was entirely removed in about three weeks. Case LXXIV.—A lady aged 45, after the menses had ceased for four months, was seized with headach, sense of weight in the head, much oppression and double vision : the pulse was at first 72, but soon rose to 100. On the first day, she was bled to twenty-eight ounces, with little relief. On the 2d, topical bleeding, blistering, and smart purging were used, but the symptoms continued unabated. On the 3d day, another bleeding of twenty ounces gave a turn to the com- plaint, and in a few days more, with brisk purging and spare diet, it terminated favourably. The last symptom that yielded was the double vision. It subsided slowly, the two images gradually approaching nearer to each other, but it was not entirely gone for nearly a fortnight. Case LXXV.—A girl aged 7, had severe headach, impa- tience of light, fever and slight delirium, followed by stupor, squinting, and great obstinacy of the bowels. The tongue was at first foul, but became clean after a day or two. Topi- cal bleeding and blistering were employed, with various active purgatives, which produced little effect; and the symptoms continued unabated for a week, during which she was con- sidered as being in a hopeless state of hydrocephalus. At the end of the week, strong purging being produced, she reco- vered rapidly, and in-a few days was free from the complaint. Case LXXVI.—A young lady aged 11, of a family in which several had died of hydrocephalus, on September 21, 1817, had severe headach, giddiness, and much vomiting; the pulse natural. After topical bleeding and purgatives, she was relieved on the 22d. On the 23d, she still complained of headach, and the pulse fell to 60. On the 24th, the pulse fell to 50; there was much headach, with great oppression approaching to coma, and dilatation of the pupil. Two bleed- ings from the arm were now employed with much relief; the second produced syncope. On the 25th, the pulse was from 80 to 90, and all the symptoms were relieved. The com- plaint then subsided under the use of purgatives and cold ap- plications ; and in five or six days more she was in her usual health. 132 INFLAMMATORY AFFECTIONS OF THE BRAIN. Case LXXVII.—A lady aged 15, had violent headach for several days, with impatience of light, followed by transient fits of delirium; and this by squinting, double vision, and stupor hording upon coma; the bowels very obstinate, with occasional vomiting. The pulse was very variable, being sometimes extremely frequent, and at other times little above the natural standard. There occurred paroxysms of violent aggravation of the pain, which produced screaming and agi- tation of the whole body, and at times there was a threatening of convulsion. This very violent case was treated by repeat- ed general and topical bleeding, blistering, purgatives, and mercury given so as to affect the mouth. Under this treat- ment the complaint subsided; but after she appeared to be well, it suddenly returned with the same violence as before, and was again treated by the same remedies. In this manner she relapsed five or six times, and at last got well after the case had been drawn out to many weeks. Case LXXVIIL—A lady aged 21, in July, 1815, had symptom^ of continued fever, which went on for three weeks. The pulse then came down to 84, and the tongue became clean, but she had much headach, transient fits of delirium, and stupor bordering upon coma, and the pulse rose again to 120. In this state she continued a fortnight, with every ap- pearance of an affection.of the brain of the most formidable character, and without being at all relieved by the remedies which were employed, namely, repeated topical bleeding, blis- tering, and large doses of calomel. The calomel did not af- fect the mouth, and had very little effect upon the bowels. At the end of the fortnight she was suddenly seized with co- pious discharge of blood from the bowels. This continued three days, and left her extremely pale and exhausted, but she was free from stupor, and the headach was much relieved. In five or six days more she was well. Case LXXIX.—A gentleman aged 17, 1st February, 1810, had symptoms of continued fever for a week; the skin then became cool and the tongue clean; but he had severe head- ach with considerable stupor; pulse 100. Genera] bleeding was then employed, followed by purging and mercurial fric- tions ; and after a few days the symptoms were alleviated; but there was still much headach, with oppression, and a re- markable slowness of speech. On the 14th, there was increase treatment. 133 of stupor; pulse 86; the tongue clean; the skin cool. On the 16th, there was much incoherent talking and unmanage- able delirium; after which the stupor again increased, the pulse continuing about 84. On the 19th, there was partial relief after smart purging; but on the 20th, the stupor had re- turned as before, and by the 22d, had increased to perfect coma; the pulse about 100. He now lay in a state of perfect coma for four days, during which time various medicines were given with difficulty, and with little effect upon his bowels. On the 27th, purging was at last produced to the extent of fourteen evacuations in the course of the day, with complete relief of all his symptoms. On the 28th, there was some de- lirium, which subsided in another day. For a week he con- tinued to complain of some headach, and a feeling of weight in his head; but by the 10th of March, he was free from complaint. To these cases, as they stood in the former edition, I shall only add the following, which presents some features of much interest. * Case LXXX.—A boy aged 12, the son of a medical friend, had scarlatina mildly in the spring of 1833. Nearly a month after, he was affected with slight anasarca of the face, and af- ter this had continued several days, he had some vomiting, and appeared languid. About a week after the appearance of the anasarca, he complained one morning of headach, and had some vomiting; pulse slow and rather languid. About eleven o'clock in the forenoon, he suddenly lost his sight; and to- wards the afternoon, he passed into a state bordering on coma. He still complained of headach, but the pulse was not above the natural standard, soft and languid. Topical bleeding having been employed without relief, I saw him at night, and advised general bleeding to 12 ounces to be followed by ac- tive purging, and cold applications to the head. During the bleeding the pulse rose both in strength and frequency. Next morning I found him quite sensible, but entirely blind ; there was still some headach, but less than formerly, and the pulse was stronger, and not frequent. He was again bled to 12 ounces, and the purgatives repeated. After five or six evacu- ations from the bowels, his sight began to return, and in the evening was entirely restored. Next day he was free from complaint, and has ever since enjoyed good health. APPENDIX TO PART FIRST. The preceding observations conclude the present imper- fect outline of the first part of our subject, The inflam- matory affections of the brain. Before proceeding to the second part, I shall introduce in this place a few ob- servations upon certain affections, which are most allied to the first class, and in a practical point of view are often ob- jects of wery great interest; they are referable to the following heads: I. Tubercular Disease of the Brain. II. Certain Affections of the Bones of the Cranium, III. Certain Affections of the Pericranium. SECTION I. OF TUBERCULAR DISEASE OF THE BRAIN. When we have an opportunity of observing tubercles in the brain in their early stages, in consequence of the patient having died of some other disease, we find them presenting the same characters as in other parts of the body. They are generally solid bodies, of firm consistence, and whitish colour, varying from the size of a pin head, or a small pea, to that of a walnut or a small egg. We find them in every part of the brain, either embedded in its substance, lying on the surface or attached to the membranes. When they have attained a considerable size, they present when cut into, the usual whitish- coloured or cheesy matter generally enclosed in a cyst; and TUBERCULAR DISEASE OF THE BRAIN. 135 in the fatal cases, we find them more or less approaching to a softened state, or partial unhealthy suppuration. They occur in persons and in families, in whom a tendency to tubercular disease has otherwise manifested itself; and they are very of- ten combined with tubercular disease in other organs. This is remarkably exemplified in the first of the following cases, in which all the three great cavities were at once extensively affected. The symptoms accompanying tubercular disease of the brain, in its early stages, are often exceedingly obscure and variable ; perhaps little more than a tendency to headach, which assumes no formidable character, or sometimes assumes the appearance of what has been called the periodical headach, or the sick head- ach. The symptoms may go on for a long time in this man- ner without exciting any alarm, until the disease suddenly as- sumes a more active character and is speedily fatal. This termination seems in general to be connected with inflamma- tory action of the cerebral substance ; and we find upon dis- section, either extensive effusion or extensive ramollissement of that part of the brain in which the principal tubercular masses are situated. In other cases, we have every proof that masses of a very large size had existed without producing any symptoms, until an attack took place which went through the usual course of hydrocephalus. Examples of tubercular dis- ease in the brain have already occurred in connexion with some of the diseases formerly referred to. I add the follow- ing cases as illustrating the affection in its more pure and sim- ple form. Case LXXXI.—A young lady aged 15, fell into bad health in the beginning of the year 1822, complaining at that time chiefly of pain in the bowels, with bad appetite; and she be- came languid and sallow. She went through the usual course of treatment for such affections, under the care of Mr. William Wood, with apparent benefit; but after some time she began to have cough, with uneasiness in the chest, and these symptoms then became the object of attention. Some time after this she began to complain of headach, for which she was treated with topical bleeding and blistering, and again experienced relief. In this manner she went on for several weeks more, com- plaining sometimes of her belly, sometimes of her breast, and sometimes of her head. The pain was never severe in any of these situations, but she was seldom without uneasiness in 136 TUBERCULAR DISEASE one or other of them. Her bowels at first had been rather loose, but afterwards were natural, or easily kept open by mild medicines. When I saw her along with Mr. Wood, in the beginning of March, she was considerably reduced in flesh and strength; she was confined to the house, but able to be up and dressed during the day. She had a small frequent pulse, little appetite, some cough, and occasional uneasiness in the chest; there was frequent pain in the head, and febrile flushings took place in the evening. She now made little complaint of her bowels, which were easily kept open, and the stools were natural. It was evident that there was disease in all the three cavities, though it was doubtful in which of them it was to assume the fatal character, until the 15th March, when the headach became more severe, so as to confine her to bed. It then went on in the usual manner with dilated pupil, squinting and^coma ; and she died on the 20th. Inspection.—The ventricles of the brain were distended with fluid. In the substance of the right hemisphere, there was a tubercular mass of considerable size, partly softened; and there were several smaller masses of the same kind in the sub- stance of the cerebellum. The lungs were studded throughout with innumerable small tubercles, all in the solid state. The abdomen presented a most extensive mass of disease, the whole of the intestines being agglutinated together by adhe- sion ; and the mass thus formed likewise adhered extensively to the parietes of the abdomen and to the omentum. Case LXXXII.—A young lady aged 18, had enjoyed good health, except from a scrofulous sore on the left arm, till about the middle of February, 1822, when she began to complain of headach. There was fever, with oppression and loaded tongue; and the headach became so severe, that Sir George Ballingall was induced to treat her in the most active manner by general and topical bloodletting, &c. When I saw her along with him, about the end of the first week of her illness, she had still much headach, with a look of great oppression, but was quite sensible. The pain was chiefly referred to the back of the head and neck, and was much aggravated by mo- tion, even by being raised up in bed in the most gentle man- ner. The tongue was covered with a dense white crust, and the pulse was frequent and rather weak. After farther topical bleeding, purgatives, &c, there was a gradual improvement; and, at the end of the second week, the tongue was clean, and OF THE BRAIN. 137 the look of oppression and stupor was gone. But though her general aspect was now greatly improved, she was not free from uneasiness in the head, and she did not recover strength. After an interval of partial relief, the headach again increased, with a look of much languor and oppression. After continu- ing a few days in this state, she died rather suddenly. At the morning visit of the day in which she died, she appeared sensible to every impression, and answered questions distinct- ly when roused. Her death took place about five weeks after the original attack. Inspection.—There was considerable effusion in the ventri- cles of the brain. In the substance of the right hemisphere, there was a soft tubercular mass of large size ; and there was considerable ramollissement of the cerebral substance surround- ing it. There were two smaller tumors of the same kind in the cerebellum. There were numerous tubercles in the lungs not suppurated. There was much disease of the uterus and ovaria, which were considerably enlarged; and the Fallopian tubes, in particular, were very much enlarged, and distended with a soft cheesy matter of a yellow colour. In this case it seems probable that the attack of the middle of February was continued fever, and that the disease in the brain was thereby excited into action and hurried on to a fa- tal termination. Case LXXXIII.—A boy aged 9, in January, 1821, began to complain of headach. It was usually accompanied with pain about the umbilicus, and attacked him daily, the attack commonly continuing from half an hour to two or three hours. The headach at first came on about two o'clock in the morn- ing, and generally continued about one hour, but the period of its duration was gradually extended to three or four hours. The period of attack also gradually became later, until it ad- vanced progressively to five in the afternoon; it did not be- come later than this. The attack usually occurred every day, and generally went off with vomiting. During the attack, the pain was most violent, so as to incapacitate him from any ex- ertion ; but during the rest of the day, he was lively and play- ful, and made no complaint. He went on in this manner for six months. In the beginning of July, he was seized with fever and pain in the bowels, and was confined to bed. The headach now became constant, and there was frequent vomit- 18 138 TUBERCULAR DISEASE ing. After some days the vomiting ceased, but he continued to have fever, with considerable permanent headach ; and at the end of a fortnight from the commencement of the febrile attack, he died rather suddenly without coma or any affection of the senses. Inspection.—The brain was quite healthy, and there was no effusion in the ventricles. In the left lobe of the cerebellum, there were two tubercular masses, the size of large hazel nuts ; and there was another similar tumor betwixt the two lobes; they were round and firm, and internally presented a yellowish cheesy consistence. In the thorax, there was extensive adhe- sion, but the substance of the lungs was tolerably healthy. In the abdomen there were slight adhesions of the viscera. Case LXXXIV.—A child aged 3 years, of a family who had suffered much from various forms of chronic disease, had been for some months affected with a moveable swelling on the arm, of a strumous character, and was liable to discharge of matter from the left ear. He was otherwise in good health until the beginning of April, 1827, when he was observed to have a peculiar unsteadiness in his limbs in walking, and a pe- culiar want of control over his arms in attempting to lay hold of any object. From this time he showed a disinclination to walk, but no other symptom was taken notice of till the mid- dle of May, when he complained of pain in the back of his head, especially in the left side behind the ear. He was now confined to bed, and was fretful and feverish. On the third day from the commencement of these symptoms, he began to squint, and about the same time to be affected with convul- sive attacks, which generally occurred three or four times in a day; they affected at first the whole body, but afterwards were confined to the right side, and were generally accompa- nied by distortion of the eyes, and a degree of stupor, which however was of short continuance; his pulse was generally about 120. He lived in this state for twelve days, and no particular change of symptoms took place, except that a few days before death the pupils* became dilated and insensible. He appeared to be comatose only on the last day of his life, having continued till that time to be sensible to every thing, and to take his food readily. I saw him along with Mr. Mac- farlane, and all the usual remedies were employed without re- lief. Inspection.—There was considerable effusion in the ven- OF THE BRAIN. 139 tricles; the brain was in other respects healthy. In the pos- terior part of the cerebellum there were two tubercles the size of large walnuts. They were situated one in each lobe, and completely imbedded in the substance of the cerebellum. Ex- ternally they were firm and of a yellow colour; internally they showed the usual appearance of unhealthy suppuration; there was extensive ramollissement in the substance of the cerebel- lum ; and there was extensive effusion in the spinal canal, both betwixt the bones and the dura mater of the cord, and betwixt that membrane and the pia mater. The substance of the cord seemed much softer than natural, especially at the upper part, where, in consequence of its softness, it had given way in opening the spine. On the subject of tubercular disease in the cerebellum, I shall only add the following remarkable case, showing in a very striking manner, the remissions which take place in the symptoms in diseases of this class, and the periodical charac- ter which they sometimes assume. Case LXXXV.—A gentleman aged 34, in the year 1825, first began to be affected with occasional attacks of headach, which were usually accompanied by vertigo and dimness of sight. In 1827, the pain became more severe, and was dis- tinctly referred to the occiput and superior part of the neck. He had generally remission of it through the day, and aggra- vations in the evening. In the spring of 1828, the symptoms increased in severity, but he received considerable relief from blistering. In the summer he went to the country, where his general health was much improved, and his headach greatly mitigated. He continued in this improved state till May, 1829, when the attacks of headach were again aggravated, accom- panied by giddiness, and on one occasion he fell from his chair. In October of the same year, he began to be affected by a most distressing sensation of throbbing referred to the back part of the head; and he was also affected with vomit- ing, which Continued without intermission for three weeks. The paroxysms of headach were now aggravated to an intense degree of severity. They occurred chiefly in the evening, from six" o'clock till midnight,—but also at other times of the day. During the more severe attacks, his face was flushed,—the vessels on the temples were remarkably distended, and he lay in a state nearly of unconsciousness, unable to speak, and with his hands and arms spasmodically contracted. He still 140 TUBERCULAR DISEASE had occasional vomiting and intense acidity of the stomach, and several times complained of double vision. The pulse was generally natural. His situation was now considered as nearly hopeless ; and no relief was obtained from any reme- dies ; but after five or six weeks of intense suffering, the symp- toms gradually remitted, and during several weeks in Decem- ber and January, he continued almost free from headach; he was able to walk out, and his general health was greatly im- proved. In February, 1830, the symptoms again increased, but the pain was now chiefly complained of above the eyes; the remissions also were more complete, and, upon the whole, his sufferings were less severe than during the attack in Novem- ber. In March, his complaints again subsided, and he was able to take a good deal of exercise in the open air, and to attend a good deal to his business. He had still occasional attacks of headach, but they were not severe, and his condition was considered as much more favourable than it had been for a long time. In the middle of April, the paroxyms of headach became more severe, but by no means in the degree in which they had occurred on former occasions. He was not confined; and no degree of apprehension was excited until the 24th, when, in one of those paroxysms, he suddenly expired. Inspection.—The ventricles of the brain contained from three to four ounces of limpid fluid ; but the surrounding parts were entirely healthy. Imbedded in the substance of the left lobe of the cerebellum there was a tubercular mass, the shape ^ and size of a very small walnut. Externally it was firm, and presented the usual appearance of the scrofulous tubercle ; in- ternally it was softened, with the common appearance of un- healthy scrofulous suppuration. The substance of the cere- bellum around it was entirely healthy. No other appearance of disease was discovered in the head ; and the other viscera were sound. The following case, for which I am indebted to Dr. Combe, of Leith, while it affords a good example of tubercular disease of the brain, is interesting from the singular coincidence of the two forms of paralysis, on the opposite sides of the face ; the one connected with the division of the portio dura, the other with the disease in the brain. Case LXXXVI.—A man aged 36, about a year before his death, had a tumor extirpated from behind the angle of the OF THE BRAIN. 141 jaw, on the left side, and immediately after the operation, pa- ralysis took place in the left side of the face, in consequence of which his mouth was distorted to the opposite side in a most extraordinary degree. About six months after this, he began to complain of headach, and giddiness, which often gave him the appearance of intoxication, and after some time these symptoms were followed by impaired vision, occasional strabismus, and a considerable degree of deafness ; and at last by drowsiness, coma, convulsions, and death. As these symptoms advanced, he became affected with numbness, and loss of power of the right side of the face, which increased very gradually. During the increase of this, the distortion of his mouth gradually diminished, and for some time before his death his countenance had become entirely symmetrical.— Both sides of his face were now entirely paralytic, but with this difference, that on the right side the feeling was also lost, while on the left the feeling was entire. Inspection.—In the centre of the middle lobe of the right hemisphere of the brain, there was a tubercle about an inch long, and three-fourths of an inch in breadth. At its lower part it was attached to the cerebral substance, but the rest of it was detached, being surrounded with dark-coloured pus. In the vicinity, there was increased vascularity with softening of the cerebral substance. I shall only add on this subject one remarkable case of a tubercular mass of very great size attached to the falx, which must have existed for a long time without producing any symptoms. Case LXXXVII.—A boy aged 7, had been for more than a year affected by scrofulous sores, and during that time had been in a declining state of health, without any local internal symptom, till six weeks before his death, when he began to complain of pain in the forehead, and considerable uneasiness in the abdomen. His pulse was natural, but his appetite was bad, his tongue foul, and his sleep disturbed. After the usual treatment, the pain in the belly was removed, and the head- ach was much relieved, so that for a fortnight he made little complaint. The headach then returned with much severity, and, without any other change in the symptoms, he became gradually comatose, and died after three days of profound coma. 142 tubercular disease Inspection.—There was much effusion in the ventricles of the brain, and considerable ramollissement of the cerebral sub- stance in several places. A large firm tumor adhered to the middle of the falx on the right side. It was nearly five inches in circumference at the broadest part, and about an Inch and a half in thickness. Internally, it was of a yellowish-white or ash-colour, and of a consistence resembling that of coagulated albumen. It was imbedded in the substance of the right he- misphere, where it had formed a depression. for itself, but without any adhesion to the arachnoid of the part. There were two smaller tumors the size of large nuts, and of the same appearance, also attached to the falx,—the one at its posterior, and the other at its anterior extremity, both on the right side. Another tumor of the same kind was imbedded in the anterior lobe of the left; hemisphere, and was attached by a slender filiament to the pia mater. There is reason to believe that the deposition of tubercular matter in the brain, as in other parts of the body, is often the result of inflammatory action of a low scrofulous character; that it may at first be excited by injuries or other causes of inflammation; and that it may then advance gradually in a slow, insidious manner. Case LXXXVIIL—A boy aged 8, in June, 1821, fell from a height and received an injury on the head, wThich was fol- lowed by considerable stupor. He was relieved for a time by the usual remedies ; and though he was never altogether well, no remarkable symptom occurred till the middle of October, when he complained of a sense of weight in the head, follow- ed by some stupor, with slight paralysis of the right arm and leg. He continued in this state without any farther change, till the 2d March, 1822, when he was seized with severe headach, fever, restlessness, and dilated pupil. After partial relief, by the usual remedies, he sunk gradually into coma, and died on the 17th. Inspection.—The ventricles of the brain contained about eight ounces of fluid. In the lower part of the posterior lobe of the right hemisphere, there was a firm tumor the size of an almond. The right lobe of the cerebellum was reduced to nearly a purulent consistence. Below it, and immediately be- hind the petrous portion of the temporal bone, there was a tu- mor the size of a hen's egg, externally of a firm consistence, OF THE BRAIN. 143 but internally approaching to suppuration. It adhered firmly to the dura mater, which was much thickened at the place of the adhesion. Case LXXXIX.—A boy aged 7, (for whose case I am in- debted to the late Dr. Gregory,) in the beginning of the year 1811, received a severe injury of the forehead and nose by a fall, his nose being nearly flattened by it. From this time, he complained of headach, and, after two or three months, be- came near-sighted. Soon after, his sight became indistinct, and after four or five months more, this was followed by blind- ness. About this time he began to be epileptic, and to be af- fected with weakness of the lower extremities, which gradual- ly increased to perfect paraplegia. He died in April, 1812, after coma of three days, his intellect having continued entire till that time. Inspection.—A firm white flat tumor, the size of a large bean, lay over the junction of the optic nerves. The ventri- cles contained twelve ounces of clear fluid. The left lobe of the cerebellum was much indurated ; and the right lobe was reduced to a mass of unhealthy scrofulous suppuration. Nearly analogous to tubercular disease in-the brain, appear to be those cases in which albuminous matter in a pure state is deposited in cysts in various parts of the brain, or under the membranes. The symptoms connected with some of these are very remarkable. Case XC.—A woman aged about 50, had been ill for a year or more before her death, during the greater part of which time she had been confined to bed, or able to be out of it only a part of the day. She was affected with violent paroxysms of headach, which usually attacked her in the night or about four o'clock in the morning, and generally continued for two or three hours, when it subsided, and left her tolerably easy till the same time the following night. Sometimes the attack was of shorter duration, going off in a quarter or half an hour. During the paroxysm the pain was most intense, and was sometimes accompanied or succeeded by delirium, and some- times by coma of short duration ; on several occasions squint- ing was observed. Her death was rather sudden ; she went to bed at night in her ordinary health, and was seized with her usual paroxysm, which went off about the common time ; 144 TUBERCULAR DISEASE but it returned a second and a third time, and she died early in the forenoon., Inspection.—There was considerable effusion in the ventri- cles of the brain, without any disease of the substance. Be- tween the lobes of the cerebellum, at the upper part, there was a firm white cyst containing upwards of an ounce of transpa- rent albuminous matter of a pretty firm consistence, and in the lower part of the cyst there was some coagulated blood mixed with it. Case XCI.—A man aged 50, had been for some time af- fected with cough and bloody expectoration. In June, 1818, he was seized with headach, and some confusion of thought, which appeared chiefly in a tendency to misapply words. The pain, which was referred chiefly to the forehead, increased in severity, and attacked him in violent paroxysms. The sight of his right eye was impaired, and soon after lost; and his speech became indistinct, and after some time inarticulate.— Six weeks after the commencement of these complaints, all the symptoms were increased. Violent paroxysms of pain were excited by the least motion, and even by change of pos- ture in bed. He seldom attempted to speak} but he often pressed his hand on his forehead, and seemed to have unea- siness in his right arm. He had some squinting, with gene- ral weakness and paleness, and his intellect was evidently im- paired. He died in August in a state of coma. The pulse had been usually natural, sometimes slow. Inspection.—In the substance of the left hemisphere of the brain, towards the posterior part, there was a soft and vascu- lar cyst, containing about two ounces of a thick colourless al- buminous fluid, coagulable by heat, and exactly resembling the albumen of an egg. The cerebral substance round the cyst was softened ; the brain in other respects was healthy.— The ventricles contained a small quantity of serous fluid, and had no communication with the cyst. Case XCII.—A child, aged at the time of his death 3 1-2 years, died in May, 1823, after having been for nearly three years affected with almost constant convulsion. The disease began at the age of eight months, and at first assumed the form of a singular convulsive starting of the left arm and leg, compared by an intelligent surgeon who saw him at the time, to the motion which is produced by the electric shock. By OF THE BRAIN. 145 degrees this passed into more regular convulsion, which after- wards affected the whole body. It occurred generally five or six times every day; occasionally there were intervals of a day or two, and at one time of two weeks ; but, after such in- tervals^ the disease generally recurred with double severity. For a year or more before death, the child had been in a state of general palsy, except an occasional motion of the left hand. He was in a state of perfect idiotism, and never attempted to speak; he swallowed food when it was put into his mouth ; and occasionally expressed his wants by peculiar cries, which his mother came to understand. Notwithstanding the com- plete want of voluntary power, the convulsive movements con- tinued with great severity, and all the long bones of the ex- tremities were twisted by them in a most singular manner. Inspection.—The bones were all very soft, and the long bones of the extremities singularly twisted ; the head was of a natural size, and the anterior fontanelle was open. The left hemisphere of the brain, over rather more than its anterior half, was remarkably depressed by a mass of pellucid albumi- nous matter, which was lodged under the arachnoid; it re- sembled in appearance the albumen of an egg, but was much firmer, so that pieces of it could be separated from the mass and lifted up. Parts of the mass being thrown into boiling water became immediately opaque and coagulated. The brain in other respects was healthy. In these cases the fluid contained in the cysts was of an air buminous character. But it may also be found serous even in cases of very long standing. A very remarkable case is men- tioned by Andral. The patient was affected, at the age of 8 years, with palsy of the left side, which continued till puberty, and then gradually disappeared, leaving the limbs which had been affected, however, weaker than those of the other side, and much smaller in size. He lived in this state to the age of 72, and then died exhausted, without any symptoms in the head, or palsy. About the middle of the right hemisphere, there was found a cyst, formed in the sub-arachnoid cellular texture, full of a serous fluid, and the size of a small apple,— (" pomme d'api.") I conclude this part of the subject with the following re- markable case, showing the most extensive destruction of the substance of the brain that has ever occurred to me. It seems 19 146 TUBERCULAR DISEASE to have been originally a tubercular mass mixed with some masses of an albuminous character, and at last terminating by most extensive ramollissement. When we consider the extent of the disease, and the state of health of the patient a few hours before death, it is probably almost unique in the history of diseases of the brain, and shows us in a very striking man-1 ner the imperfectibn of our knowledge in regard to the symp- toms arising from cerebral disease. Case XCI1I.—A young lady who, between her 14th and 17th years, had suffered considerably from chronic ophthal- mia, was attacked in her 18th year with paralysis of the face. The mouth was twisted to the right side ; the orbicularis of the left eye was affected, so that the eye could not be shut without a great effort; the sight of that eye Was much impair- ed, and there was numbness of the whole left side of the face; the pulse was natural; The affection had begun with pain re- ferred to the left ear. She was bled generally and topically, and freely purged, and the affection disappeared in six or eight days. Some time after, she had a second attack of the same kind, which also subsided in the same manner. After this she became liable to attacks df giddiness, accompanied by in- distinct vision, and followed by vomiting. These attacks were of frequent occurrence, but did not in general continue above a day or two, and in the intervals she was in perfect health. These symptoms went on for about a year. In her 19th year, while she was one day sitting at dinner, she sud- denly fell from her chair in a state of complete insensibility, with general muscular contraction or rather rigidity, but with- out convulsion; and in this state she remained for nearly two hours; This occurred in the month of June 1822, and there was no recurrence of the attack till December following, when she had one exactly similar. A third took place in February 1823 ; and a fourth in June of the same year. From the first occurrence of these paroxysms, the attacks of giddiness became more distressing, and were then for the first time accompanied by headach, which was chiefly referred to the left temple and the left ear; and the attacks were often followed by thin wa- tery discharges from the ear. After the fourth paroxysm of the comatose affection, she began to have indistinctness of vi- sion. At this period she Used sea-bathing, by which the headach was increased, and the indistinctness of vision pass- ed into a considerable degree of amaurosis. For the latter af- OF THE BRAIN. 147 fection, an emetic was now recommended to her, the opera- tion of which was immediately followed by a violent attack of the paroxysm of insensibility, and these continued to recur at .short intervals to the time of her death. In regard to the pe- riod of their occurrence, the account of her friends was, that for a fortnight they attacked her generally every day, and for the next fortnight she was entirely free from them. They .continued to exhibit nearly the same characters as formerly described, namely, insensibility, with muscular rigidity; and there never was any appearance of convulsion, except in one instance, during the whole course of the disease. The attack generally continued from half an hour to an hour; and, except the imperfection of vision, her general health was so good, that she was married in February 1824, which was about two months before her .death. At -this time she first came under -the care of my friend, Dr. Ross, to whom I am indebted for the preceding history; and the leading symptoms then were, frequent recurrence of the paroxysms of insensibility, with vi- olent headach, accompanied by giddiness and sickness. 1 here was a great degree of amaurosis, but the pulse was .natural, and her health in other respects good. Under the use of ex- tract of stramonium, the paroxysms were now suspended, the vision was very much improved, and her general health and spirits were such, that the evening before her death was spent cheerfully with a party in the house of a friend. She return- ed home about eleven o'clock at night, and went to bed ap- parently in her usual health. About eight o'clock in the fol- lowing morning, she was found in a state of insensibility with rigidity of the body; she was supposed by her friendsto be in°one of her usual attacks, but when she was seen by Dr. Ross, a short time after, he found that she was dead. I was present at the examination of the body. Inspection.— The brain externally appeared healthy, but when a thin section was cut from the upper part of the left hemisphere, a cavity was exposed, through which a probe passed in every direction without any resistance, through near- ly the whole extent of the hemisphere. This, upon farther examination, was found to arise from the whole hemisphere being in such a remarkable state of decomposition or softening, that it formed one great cyst, full of soft pultaceous matter, inclosed in a very thin covering, formed by the healthy cere- bral matter on the surface. The healthy portion forming this covering, in many places did not exceed a quarter of an inch 148 DISEASES OF THE BONES OF THE CRANIUM. in thickness ; and at the thickest parts, which were on the upper surface of the brain, did not exceed one-half or three- fourths of an inch. The contained matter was a thin soft pulp, mixed with portions of a pellucid albuminous substance, which coagulated when thrown into boiling water. This mat- ter was chiefly in irregular masses, but there were some firmer portions of it which could be separated in the form of distinct round nodules, resembling hydatids. On examination, how- ever, they were found not to be hydatids, but uniform masses of the albuminous matter in a more concrete state. On the external part of the hemisphere, lying over the petrous por- tion of the temporal bone, there was a tumor the size of a pi- geon's egg, adhering firmly to the inner surface of the dura mater. Externally, it was irregular as if formed of a conge- ries of smaller tumors; internally, it was composed partly of a reddish soft fleshed-coloured matter, and partly of a semipel- lucid albuminous substance, in nodules of various degrees of firmness. When thrown into boiling water, the whole mass assumed a uniform opaque white colour, and a hard cheesy consistence. The left ventricle was entire; it contained a small quantity of serous fluid, and was separated from the dis- eased mass by a very thin septum. The right hemisphere was healthy, except on the inner part of the anterior lobe, which was considerably softened. It appeared to every one who witnessed the dissection, that the left hemisphere had been considerably enlarged, and the right diminished in the same proportion, the falx being sensibly pressed towards the right side. The optic nerves seemed softer than natural; the cerebellum was healthy. SECTION IT. OF CERTAIN AFFECTIONS OF THE BONES OF THE CRANIUM. I was led to make some researches on this subject by the following case.— CasE XCIV.—A woman aged 48, about a year before her death, fell down a stair, and received various injuries, espe- DISEASES OF THE BONES OF THE CRANIUM. 149 cially one on the head, which confined her to bed for some days. From this time her health was bad; she generally complained of fixed pain of the head, and had a very disor- dered state of the stomach and bowels. She was able, howT- ever, to attend to the ordinary duties of her family, till about three weeks before her death, when she was seized with fever and outrageous delirium. These symptoms subsided after a bleeding; and next day, she had erysipelas of the face, which went off in a few days. She was then able to be out of bed, but complained of a fixed and deep-seated pain in the right side of the head, a little above the ear, and there was discharge of matter from the right ear. She continued in this state, sit- ting up part of every day, till three days before her death, when she became comatose, with partial paralysis of the left side, and frequent convulsive motions of the right arm. She died on the third day after the occurrence of these symptoms. Inspection.—The cranium was very easily opened, the bones being remarkably soft. On raising the skull cap, the inner surface of the whole upper part of the cranium exhibited a singular state of disease. The inner table seemed to be want- ing through its whole extent, and there appeared the rough, irregular, and cancellated structure of the central part of the bone. Betwixt this surface and the dura mater, there was a deposition of soft adventitous membrane of a yellowish colour, varying from one-twelfth to one-eighth of an inch in thickness. In raising the skullcap, this membrane, in some places, adher- ed to the dura mater, leaving exposed the irregular cancellated structure of the bone ; and in other places, it adhered to the bone, depriving the dura mater of its natural appearance. The parts affected by this singular state of disease were, the fron- tal bone above the orbitar plates, the whole of both parietal bones, the squamous portion of both temporal bones, and ra- ther more than the upper half of the occipital bone. The greatest erosion was on the parietal bones, where several por- tions were very thin and transparent, and a few points were perforated. The external surface of the cranium was of a na- tural appearance, except at the few points where the erosion had perforated the bone by very small apertures. In the low- er part of the right hemisphere of the brain, towards the pos- terior part, there was an extensive abscess. The brain in other respects was healthy. On the petrous portion of the right temporal bone, the dura mater was of a dark colour, and detached from the bone; but the bone was healthy. 150 DISEASES OF THE BONES OF THE CRANIUM. I find no case described by any writer exactly resembling this remarkable affection of the bone. There was a complete destruction of nearly the whole inner table of the cranium; and in its place, a deposition of a soft adventitious membrane, by wThich the dura mater was everywhere agglutinated to the diseased bony surface. This disease must have been going on for a considerable time; the abscess of the brain was pro- bably recent, and the immediate cause of death. The patient was a respectable married woman, and there seemed no ground for suspecting a syphilitic taint. Such a disease therefore is probably to be considered as the result of a slow inflammatory action affecting the bone, and gradually destroying it by caries. Such a disease may originate in an injury, or may commence without any obvious cause. It affects most commonly the ex- ternal table of the skull, though it may likewise affect the in- ternal ; but I have seen no case described by any writer in which it was entirely confined to the internal table. A lady, mentioned by Mr. Howship,* at the age of 15, received a slight blow on the right side of the head, and for 30 years after, was liable to severe headach, which was constantly referred to that spot. She then became drowsy, and her vision was im- paired, and at the age of 50 she died comatose. At the seat of the original injury, the bone, to the extent of a crown piece, was so thin from absorption as to be almost transparent. The dura mater at this part was altogether removed, and the brain beneath was of a dark livid colour, and much indurated; and this disease extended through the whole middle lobe. In a case mentioned by Desault, death followed a blow on the head after a month:; the bone was externally sound, and its cover- ings were healthy; but the internal table was blackened through the whole extent of one of the parietal bones ; the dura mater adhered to the bone as firmly as to the other parts of the cra- nium ; and there was suppuration on the surface of the brain. This was probably an earlier stage of that disease which oc- curred in Case XCIV.., and in a more limited form in Mr. Howship's case. A man aged 28, whose case is related by Mr. Wathen, was affected with a swelling the size of a pigeon's egg on the left parietal bone. It gave him no pain, and continued nearly stationary for a year and a half, when a similar tumor appear- ed on the side of the osfrontis. These swellings increased,, *'Praeli«al Observations in Surgery and Mopbid Anatomy. DISEASES OF THE BONES OF THE CRANIUM. 151 and after* several weeks were united, so that they nearly co- vered the left side of his head. The swelling was colourless and without pain, and about this time he suffered some con- vulsive attacks. Caustic was applied to the posterior part of the tumor, and, when the eschar separated, the integuments were found to be two inches in thickness; and the bone be- neath was extremely irregular, sending up sharp bony Spicu- le into the tumor, some of which were an inch in length. A similar eschar being taken out from the anterior part showed the same appearances. Much thin ichorous matter was dis- charged from the openings with some pus. He had now fre- quent pain and fever, with occasional convulsion and delirium; but continued to go about, and could walk many miles. He died gradually exhausted, but retaining his faculties to the last, two years and a half after the commencement of the com- plaint. On dissection, the whole left side of the cranium was found perforated by numerous openings, between which there were bony ridges, filaments, and processes of a variety of shapes; the sharper spiculae piercing the substance of the dis- eased integuments. t The two largest perforations correspond- ed to the seats of the two original tumors, and corresponding to these there were two small abscesses in the brain. The inner surface of the bone was diseased in the same manner as the outer, and the dura mater was connected to it by a soft fungus, which arose from every part of the diseased bone.* Morgagni mentions extensive caries of the back part of the cranium, with remarkable thickening of the dura mater, which originated in a blow, and proved fatal after six years ; and in a young man who died epileptic, after having suffered long from intense headach, Zacchias found the inner table of the occipital bone carious to a small extent, the other table-being sound. A man, mentioned by Dr. Clossy, became epileptic after a blow on the head, and the fits returned several tjmes a day for three years. A fulness was perceived at the seat of the injury, which, being exposed by an incision, was found to be an elevation of the bone, namely, a part of the left parietal. At this place the trephine was applied, and the bone on per- forating it was found " cellulous and spungy, with pus in the midst." The man died comatose a few days after the opera- tion, and on inspection, there was found a circular asperity on the inner surface of the bone about the size of a crown piece, * Medical Observations and Enquiries, vol. v. 152 DISEASES OF THE BONES OF THE CRANIUM. with several small abscesses in the membrane the size of peas.* The cases now referred to may be considered as examples of an uncommon modification of the disease of the bones of the head, in which it is principally confined to the inner table. The more common modification of it is that which occurs in the outer table, or which affects the whole depth of the bone; and some remarkable phenomena are connected with the his- tory of the disease. It appears to be the result of a peculiar low inflammatory action, which may arise from injuries often very slight; or may commence without any obvious cause. Its progress is often extremely slow; but when it has been excited, it is impossible to conjecture how far it may extend. It may terminate by exfoliation of the front of the outer table, or may affect the whole depth of the bone; and it may extend to the dura mater and brain, and then be speedily fatal. A man, mentioned by Mr. O'Halloran, was seized, without any injury, with a pain in the upper part of the os frontis, which increased in violence with throbbing, so as to unfit him for his employment. After nearly four months, an abscess was formed on the part, which burst; the bone was found carious, and perforated by an opening, through which the dura mater could be seen covered with pus, and by this opening matter was discharged at each dressing to the amount of a table spoonful. The piece of bone became loose, and separated in ten days; another piece, which was also carious, was separat- ed in another week, and in a fortnight from this time the wound was healed.f This may be considered as an example of the idiopathic form of the disease. The inflammatory ac- tion probably began in the pericranium, and afterwards af- fected the bone. The disease arises more commonly from in- juries, and is often remarkably slow in its progress. A man, mentioned by the writer now referred to, received a blow on the head with a cudgel, which left some heaviness and head- ach, but without any urgent symptom, until many months af- ter, when a tumor formed on the part, and attained the size of an apple. It was opened, and under it there was found a circular aperture in the cranium the size of a half crown, ex- posing the dura mater, which was covered with pus. After some time, a fungus arose from it; and after this had been ■*Clossy's Observations on some of the Diseases of the Human Hody, p. 17. t O'Halloran on Injuries of the Head, p. 58. DISEASES OF THE BONES OF THE CRANIUM. 153 destroyed by alum, the sore healed. A boy aged 7, mentioned by Sir T. Cullum, fell with his head in the fire, it was sup- posed from a fit, and was much burned before he was observ- ed. The consequence was an extensive eschar, which did not separate for a very long time. It then left the bone quite bare, and after three months more a separation of bon,e took place in one piece, consisting of the whole of one parietal bone, part of the other parietal, and part of the occipital. Granula- tions springing from the dura mater then presented themselves, and in six months the sore was healed, except a part about the size of the mouth of a small tea-cup ; the boy being other- wise in perfect health. Between five and six years after, there was still a sore the size of a crown-piece, which discharged considerably; and at that time, "very little ossification had been produced towards the reparation of the injury." A remarkable circumstance in the history of disease of the' bone is, that when it has once been excited, it is not always confined to the part which was the seat of the injury, but may spread gradually and extensively over other parts of the crani- um. A lady, mentioned by Mr. Norris, after a fall which pro- duced at the time no alarming symptoms, was affected with pain in the head. It generally fixed with greatest severity in the os frontis, which had been the seat of the injury; and, on that place, a tumor formed, which was opened more than three months after the fall, when the bone was found carious. The trephine was then applied, under the belief that matter might be lodged within, but none was found; the disease was confined to the bone, the dura mater being healthy. A simi- lar tumor soon after formed on the occiput, under which also the bone was found carious; after some time it exfoliated, a piece being thrown off the size of a sixpence, and the wound healed. In this manner tumor after tumor formed on various parts of the head, and went through the same course. For several months pieces of the outer table only were thrown off; afterwards the whole depth of the bone was separated, at each time exposing the dura mater; and from this period the sores in the integuments did not heal. She died nine months after the commencement of the exfoliations ; and on dissection por- tions of the skull were entirely wanting, consisting, as far as can be judged from the engraving, of the upper half of the oc- cipital bone, more than one-third of both parietal bones, and a considerable portion of both temporal bones. There was 20 154 DISEASES OF THE BONES OF THE CRANIUM. not in this case the slightest suspicion of syphilis.* A woman, mentioned by Saviard, who was received into the Hotel Dieu, in consequence of an injury of the head from a fall, suffered successive exfoliations of both tables of the cranium, to such an extent, that the pieces, when put together, resembled the skullcap as it is sawn off in dissection. This process occupi- ed two years, at the end of which she was dismissed in good health, but with the upper part of the brain covered only by integuments. Hildanus relates the case of a man, on whose cranium a number of tumors formed, from which pieces of bones were discharged, at each time exposing the dura mater. The sores had healed, and the man was alive at the time when the account was written ; but affected with paraplegia. Simi- lar cases are related by Portal; in two that were under his own care, and in which he had no reason to suspect any sy- philitic taint, the disease was arrested by mercury and anti- scorbutics. Another peculiarity in the history of these affections is the slowness with which the bone falls into disease, and the length of time during which a disease, of small extent, may exist, producing urgent symptoms, but making very little progress. A lady, mentioned by M. Marechal, after a slight blow on the head, suffered constant pain in the part, often aggravated into violent paroxysms, which the most active treatment had failed to remove. After severe suffering for several years, an inci- sion was made, when a small portion of the bone was found carious. This portion was removed by the trephine, and the patient got well. The disease in this case was probably su- perficial, and it is likely that simply exposing the bone, and promoting its exfoliation, might have answered as well as this formidable operation. In other cases of this kind, the disease is at first confined to the inner table, from which it may, after a long interval, extend inwards, terminating by fatal disease in the brain : some examples of this have already been refer- red to. In other cases, again, it appears that the disease may be first external, arid afterwards, leaving its original seat, ex- tend to the internal parts. A boy, mentioned by Mr. Howship, received at school a blow on the head with a ruler. It was followed by a small sore which continued to discharge matter for six years. It then healed, and soon after his sight was impaired, and he became epileptic. The trephine was ap- * Transactions of the Medical Society of London, vol. i. DISEASES OF THE BONES OF THE CRANIUM. 155 plied at the seat of the injury without relief; he died on the third day after the operation. The bone and dura mater were sound, but the pia mater under the seat of the injury had evi- dently suffered from chronic inflammation, and the brain was much indurated through the whole extent of the middle lobe. Many surgical writers teach us that in cases in which the bone becomes diseased after wounds and injuries of the head, it is the separation of the pericranium or dura mater that kills the bone. But every practical surgeon must have seen nu- merous cases in which the pericranium was separated without any such consequence ; and others, in which the bone became carious, though the pericranium had not been separated. In a case already quoted from Desault, in which death followed a blow on the head after a month, the bone was externally sound and its covering healthy ; the internal table was black- ened through the whole extent of one of the parietal bones, yet the dura mater adhered to this portion as firmly as to the sound bone. It appears to be the inflammatory action that kills the bone, and this action, we have seen, may leave the seat of the injury, and spread from one part to another, until its progress is arrested by the powers of the constitution, act- ing in a manner which eludes our observation, and which is very little under our control. On this principle it appears, that there is in general very little encouragement for meddling with such cases by the trephine. If symptoms indicate the formation of matter beneath the bone, this must be evacuat- ed ; but perforations will remove only the danger from the lodgment of matter, and their other effects on parts thus liable to inflammatory action are extremely ambiguous. It is cer- tain, that many cases of this kind have proved fatal soon after the application of the trephine, which had been going on for a considerable time without exhibiting any unfavourable symp- tom. In a remarkable case which has been reported to me by an intelligent friend, and which had this termination, the inner table of the skull was found on inspection to be perfect- ly sound. The disease was confined to the external table, which was found to a considerable extent completely separat- ed from the internal, being confined only by the integuments. The case had originated in a slight wound which had fallen into an ill-conditioned state, and the caries had been going on for a considerable time. Free incision of the integuments is the only practice that can be required in such a case, and then 156 DISEASES OF THE BONES OF THE CRANIUM. promoting the separation of the diseased portion of bone by the usual means. Even in the ordinary cases, so familiar to practical surgeons, in which the formation of matter takes place within the cra- nium in consequence of external injuries, it is probable that the main object of attention ought to be the inflammatory ac- tion which has been excited, rather than the mere changes which are going on in the bone; and that the formation of matter is to be considered not as an effect of the disease of the bone, but as a result of the inflammation of parts from which the bone itself has also suffered. Cases are related by Mor- gagni and others, in which, after such injuries, matter was formed between the cranium and the brain, without the least appearance of disease in the bone. The communication of in- flammatory action from the bone itself to the brain and its mem- branes, is strikingly illustrated by two cases related by De Haen, in his remarks on the application of the actual cautery to the cranium. This remedy seems to have been at that time very much employed in various affections of the head ; and it was performed by first turning back a portion of the integu- ments, and then applying the cauterizing iron to the surface of the bone. In the two cases referred to, namely, a boy of 12, and a young woman of 20, this practice was employed on account of amaurosis. They both died with symptoms of ce- rebral inflammation; the former on the fourth day, and the latter on the fifth, after the operation. On dissection, exten- sive inflammation of the membranes was found, with form- ation of matter; and in one of the cases, the disease had affect- ed the substance of the brain. The cases are interesting, as showing the direct communication of inflammatory action from the bone to the parts beneath, without contusion or any inju- ry which could directly produce the death of the bone, for no caries or destruction of the bone itself was observed in either case. In the affections of the bone, which have been the subject of the preceding observations, the piece of bone, which was the seat of the disease, is in general eroded by caries through its whole extent; but a very remarkable variety of the affec- tion has been described by Professor Russel, in which the ul- cerative or carious process advances in a narrow line in a cir- cuitous manner, so as to insulate a piece of bone of some ex- tent, which is afterwards thrown out. The part thus separat- ed is in some cases perfectly healthy, and in others is more DISEASES OF THE BONES OF THE CRANIUM. 157 dense than in the healthy state, being smooth and white like a piece of ivory, and without diploe. In some of these cases, the disease took place after injuries, and in others without any apparent cause.* Another singular variety of the affection occurs, in wThich after an injury of the head, a portion of the bone disappears by absorption without ulceration of the integuments. A child aged nine months, mentioned by Mr. Howship, received an injury of the right parietal bone from a fall. There was no wound, and no urgent symptom at the time; but several weeks after the accident, the pulsation of the brain was dis- tinctly perceived at the seat of the injury, and the child be- came paralytic on the left side. At the age of four years, when the account was written, she had recovered the use of the left side, which had been improving gradually, and she was otherwise in good health ; but there was still a conside- rable deficiency of bone on the right side of the head, and when she cried or coughed, this part became tense and evi- dently swelled. A boy aged 14, mentioned by Mr. Wilmar, received a blow on the head, which was immediately follow- ed by a soft tumor about two inches in diameter at the base. After this tumor had continued stationary for two months, it was opened by a free incision, but discharged only blood in a fluid state. Under it the bone was found to be completely wanting to an extent exactly corresponding to the base of the tumor. The wound healed favourably, f Many cases have occurred in which tumors of the dura mater have occasioned absorbtion of a portion of the bone, and have appeared under the integuments. A remarkable case of this kind, which I saw along with Mr. Wishart, „ has been described by him in the Edinburgh Medical and Surgical Journal, (vol. xviii. p. 393.) Many others are on record, some of which present interesting phenomena from complications of disease. A girl aged 19, mentioned by Mr. Hill, was first seized with numbness of the left hand, which gradually extended upwards along the arm, and was accom- panied by vomiting and violent headach. After two months, the whole left side became paralytic. After another month, a small tumor like a pea appeared by the side of the bregna, which being repeatedly opened with a lancet, discharged matter with * Transactions of the Medico-Chirurgical Society of Edinburgh, vwl. L, t Wilmar's Cases on Surgery. 158 DISEASES OF THE BONES OF THE CRANIUM. some relief. After seven months more, Mr. Hill found a small opening in the left parietal bone about a quarter of an inch in diameter, but which was plugged up by a hard substance from within. The trephine being applied at this place, discovered an abscess, which discharged four ounces of matter, and a small excrescence like a wart, which had completely plugged up the opening in the bone, and had prevented the escape of the matter. There was much relief after the discharge, but protrusion of the brain took place, and she sunk gradually and died in about two months, retaining her faculties till the last two days. Much effusion was found in the ventricles of the brain, and destruction of the brain by suppuration about two inches around the opening of the skull.* It seems probable that in this singular case, the small warty excrescence on the dura mater had produced absorption of the bone, and thus af- forded a partial exit to the matter. But many instances are on record, in which, without any cause of this kind, matter formed within the cranium has found for itself an exit through the bone ; some examples of this have been already referred to; I shall only add another. A man, mentioned by Dr. M'Turk, in the Medical and Physical Journal for April, 1819, was affected with great derangement of the stomach and pain in the back of his head, which was much increased by mo- tion. His sight and hearing were impaired, especially during the more severe paroxysms of pain, when his sight was near- ly lost. He had continued in this state nearly a year, when a tumor formed on the sagittal suture, which being opened, dis- charged matter freely ; and, on examining the wound, it ap- peared that there was an opening in the suture, and that the matter came from within the cranium. The wound healed gradually in a few weeks, and from that time he was free from complaint. SECTION III. OF CERTAIN AFFECTIONS OF THE PERICRANIUM. Some obscure affections of the head, accompanied by very urgent symptoms, have been found to be connected with a * Hill's Cases in Surgery, p. 130. DISEASES OF THE PERICRANIUM. 159 disease of the pericranium, the history of which presents some very singular phenomena. In the cases related by Sir Eve- rard Home,* the symptoms in general were headach, with va- rious uneasy feelings in the head, and a painful tenderness of the scalp at a particular spot, with some degree of swelling or thickening of the integuments at the place. In one, the sight and hearing were considerably impaired, and in several of the cases there were fits resemblingepilepsy. They were treat- ed by dividing the integuments and pericranium freely down to the bone, and then dressing the wounds with lint, so as to allow them to heal slowly with suppuration.. In making the incision, the pericranium was found morbidly sensible, an I considerably thickened; and in some of the cases, indurated, approaching to the structure of cartilage. This treatment was in some of them followed by immediate and permanent relief; in others, the patient continued liable to fits or head-symp- toms upon any excess. In some of them, the incisions heal- ed without any affection of the bone being discovered ; in others, a portion of the bone appeared white and porous, or honey-combed, and a limpid fluid appeared to percolate through it, which returned immediately as often as it was wiped off.— In one of these cases, the porous piece of bone exfoliated af- ter the wound had been dressed with dry lint for six weeks ; the wound then healed, and the cure was permanent. In an- other, after waiting eight weeks for the exfoliation, he touch- ed it repeatedly with diluted nitric acid, after which it exfo- liated, and the cure was permanent. In one fatal case, he found the pericranium thickened into a mass of a fibrous bony texture, and, corresponding to this part internally, there was a similar thickening and induration of the dura mater.— Most of these cases had been treated by long courses of mer- cury without benefit, in some of them with aggravation of the symptoms. This affection seems to correspond with the disease which has been described by Mr. Crampton under the name of Pe- riostitis.! Among his cases, affecting various parts of the body, there are two remarkable examples of it in the head; the one acute, the other chronic. In the former, a boy of 14, the complaint began with a small angry tumor on the right side of the nose, from which, after some days, a swelling ex- * Transactions of a Society for the Improvement of Medical and Surgical Know- ledge, vol. iii. t Dublin Hospital Reports, vol. i. 160 DISEASES OF THE PERICRANIUM. tended along the right eyelids and forehead, with considerable erysipelatous inflammation and fever. On the ninth day, he became suddenly comatose, then convulsed, and died on the 12th. On dissection, the pericranium covering the frontal bone was found red, thickened, and detached from the bone, much purulent matter lying between them. Internally the dura mater was detached to an extent corresponding to the ex- ternal disease, and a greenish puriform fluid was effused be- tween it and the bone. The inner surface of the dura mater was also covered with pus; the pia mater was red, very vas- cular, and covered with pus to the extent of two inches on the part corresponding to the principal disease of the pericranium. The other case is that of a woman, aged 32, who was affect- ed with a tumor the size of a walnut over the left parietal bone. It was soft, and elastic, and its origin was ascribed to a blow six months before ; there was an opening in the tumor, by which a probe could be passed down to the bone. She had intense pain in the left side of the head; the right arm was wasted and paralytic, and the fingers were contracted ; both lower extremities were feeble ; her speech was indis- tinct ; she had vomiting, and frequent epileptic fits. The tumor was divided freely down to the bone, and in doing so the pericranium was found thickened, firm, fibrous, and mor- bidly sensible. It formed the principal part of the tumor. The bone under the tumor was found rough and superficially carious. A portion of it was removed by the trephine, and the dura mater under it appeared very vascular, and rather thickened. For six days after the operation she had fever, extensive erysipelas of the head, delirium, and convulsions. Suppuration was then established, and all these symptoms were relieved. In the course of the cure a slough was detached from the dura mater. A fortnight after the operation she recovered the use of her arm, and was free from complaint. Tissot* seems to have met with'this disease, and to have treated it upon the same plan, though he gives a different ex- planation of the effect of his treatment. He describes a case in which an intense pain was confined to a very small spot, at the posterior angle of the right parietal bone. It had resisted for a long time all the most powerful remedies, venesection, arteriotomy, issues, cupping, &c. He cured it immediately and permanently, by dividing the part down to the bone, and * Tissot Epist. Med. Var. DISEASES OF THE PERICRANIUM. 161 encouraging suppuration from the wound. He ascribes the cure to the division of the subcutaneous nerves. A woman, mentioned by Pouteau, received a blow behind the left ear, from the immediate effects of which she soon recovered, but she continued to be affected with pain in the spot for four years. She then had convulsions, paralytic affections, inarti- culate speech, and a long train of the most urgent symptoms, which sometimes resembled mania, and sometimes tetanus. She had still pain at the place of the injury, where a small portion of the integument was red, and very gentle pressure upon the spot produced convulsion. By a free incision down to the bone, and allowing the wound to suppurate, all these complaints were removed. A boy, mentioned by the same writer, received an injury on the crown of the head by a fall, at the age of 8 years. A painful feeling continued in the scalp at the place of the injury, and for 10 years he was liable to intense headach, which afterwards became so violent as often to occasion insensibility. At the age of 24, there was, at the upper part of the right parietal bone, the original seat of the injury and of the subsequent uneasiness, a spot slightly red and a little swelled; the hair upon it was coarse, and stood out like bristles, and pressure upon the spot produced intense pain. The pain extended to the right eye, the vision of which was obscured when the pain was violent. By a free division of the parts every symptom was removed. A similar case is related by M. Gervais, in which the pain returned pe- riodically, and the patient suffered epileptic fits daily. A slight touch on the affected part produced syncope. On divi- ding the integuments and pericranium, the surface of the bone was found carious ; this soon exfoliated, and the patient re- covered perfectly. Valsalva has taken notice of a remarkable thickening of the pericranium, in a case of long-continued headach with occasional delirium, and at last convulsion. There was serous effusion in the brain ; but he says nothing of the state of the dura mater or the bone. This singular affection Sir E. Home considers as beginning in the dura mater. Mr. Crampton thinks it commences in the pericranium. The latter opinion seems to be the more proba- ble ; for, in some of Sir E. Home's own cases, it was cured by simply dividing the pericranium. It appears, however, that in the progress of the disease, both the bone and the dura mater are apt to be affected. 21 162 DISEASES OF THE PERICRANIUM. The following is the best example that has occurred to me of this remarkable affection. Case XCV.—A servant girl aged about 20, fell backwards with a child in her arms, and received the full force of the fall upon the most prominent part of the occipital bone. She soon recovered from the immediate effects of the injury, but continued to have pain in the part; and after several months, was seized with paraplegia and retention of urine. She was now confined to bed for three or four months, after which she recovered the use of her limbs in a tolerable degree, but the retention of urine continued, and she came to Edinburgh in the beginning of 1828, which was more than a year after the accident. The paraplegia was now nearly removed, but she had still retention of urine, requiring the constant use of the catheter. On the seat of the injury on the occipital bone, a round portion, the size of a crown piece was acutely tender, and very moderate pressure upon it produced complete insen- sibility, which continued a minute or two, and returned as often as the pressure was repeated. It had the appearance of syncope, but the pulse was not affected. In this state I saw her along with Mr. Lizars, and it was agreed to make a free crucial incision through the part, and to keep the wound open by dressings so as to promote suppuration. In doing so, the pericranium was found tender and somewhat thickened, but the bone was sound. On the following day she passed her urine freely, and she continued free from complaint as long as the wound continued to discharge. It healed at the end of a fortnight, and the retention of urine returned immediately. The incision was now repeated with the same result as before, her urine being freely passed almost immediately. Various means were then employed to promote a more complete sup- puration from the wound, but it healed after two or three weeks, and the retention of urine returned as before, with con- siderable tenderness in the affected spot. A third incision was then made with the same effect as before, and various applications were made with the view of promoting exfoliation of bone, as in Sir Edward Home's cases, but without success, and the wound again healed after three or four weeks. The fits of insensibility on pressure now returned, which had not returned after the former incisions, and along with them the retention of urine. After that time repeated incisions were made with similar DISEASES OF THE PERICRANIUM. 163 results. The principal change in her situation then was, that she got free of the fits of insensibility upon the spot being pressed ; and the effect of the incisions continued longer, as on several occasions she remained free from the retention of urine for several weeks after the incisions were healed, and at one time enjoyed good health for three months. She was thus gradually restored to perfect health. Since the publication of the former edition of this volume, I have seen several cases of this very interesting affection, presenting characters similar to those which I have mentioned in the general description of it, and yielding to a free incision of the part, after the symptoms had been of long continuance, and had resisted much active treatment. One of them, in which the symptoms were very severe, and of eighteen months standing, has been described by Mr. Blacklock in the Edin- burgh Medical Journal for July, 1831. In another of the pa- tients, a clergyman, the affection seemed to have been produced by a small piece of plaster which fell on his head from the ceiling of a church. The injury at the time was of the most trifling description, but this affection gradually supervened, accompanied by a train of anomalous nervous symptoms, which greatly impaired his general health, and rendered him entirely unable for his duty for many months. He was quite cured by the incision, which had to be repeated twice. In these cases, the seat of the disease was distinctly indi- cated by the tenderness on pressure of a defined spot of the pericranium. But the following case presents some features of great interest, from the complete relief which was afforded by the same operation, though there had been no tenderness at the part, and nothing that led distinctly to the belief that disease of the membrane existed. It has led me to suppose that there are cases of untractable affections of the head in which this treatment might be beneficial, though not distin- guished by the symptoms indicating the disease which has led to these observations. Case XCVI.—A man aged 39, upwards of eight years ago, received an injury on his head from the wheel of a wagon. It produced a sore which healed in about ten days. Abou eight months after this he began to be affected with attacks of headach, which had continued to recur from that time, though sometimes at long intervals. When I saw him, along 164 DISEASES OF THE PERICRANIUM. with Mr. Kennedy, in autumn 1833, he had been suffering from intense pain in the head for two months. During the whole of this time he had been confined to bed, and unable for any kind of exertion ; every kind of active treatment had been employed without any relief; and the case now exhibit- ed every character of a fixed and formidable disease of the brain. As the principal seat of the pain, he referred to a spot on the vertex, and from this the acute pain seemed to dart in- to the centre of the brain, and particularly towards the left ear. The spot to which he pointed on the vertex, corresponded with that which he represented as the seat of the original wound; but no cicatrix could be discovered, and there was no tenderness of the integuments, nor any other appearance of superficial disease. All the usual remedies, however, having been employed without benefit, I suggested a crucial incision at this part, which was done with complete relief. The wound healed in nine days ; he soon after returned to his usual employment as a baker, and, through the winter, enjoyed good health. During the present summer, (1834,) he has had a return of headach, after exposure to great heat. After it had resisted various remedies, a repetition of the incision was con- templated, but, at present, the affection seems to be subsiding. PART II. OP THE APOPLECTIC AFFECTIONS. The remarkable condition which we call coma, or oppres- sion of the brain, appears from the preceding observations to be connected with various and very different conditions of that organ. We have seen it existing with extensive effusion, and without any effusion; and we have seen extensive effusion and extensive destruction of the cerebral substance taking place without producing it. We have seen the same want of uniformity in regard to the various other morbid conditions which have been the subjects of the preceding observations ; and, upon the whole, if we are asked, what is that condition of the brain which produces coma, I think our answer must be, that we cannot tell. We are not, however, to sit down con- tented with this profession of our ignorance, but ought, on the contrary, to consider this conclusion as a position of much importance, from which we are to commence a new course of investigation. In this course, putting away from us the theo- ries which have been so often received as established princi- ples, we must restrict our inquiries to a patient investigation of the phenomena of disease. In the investigation of the cases which are more properly referable to the head of apoplexy, we find the same difficul- ties which have met us in the inflammatory affections. A per- son previously in perfect health falls down suddenly, deprived of sense and motion, and dies, after lying for some time in a state of coma. We find on examination a large coagulum of blood compressing the surface of the brain, or filling its ven- tricles, and the phenomena of the disease appear to be distinct- ly accounted for. Another person is cut off with the same symptoms, and we expect to find the same appearances, but 166 APOPLECTIC AFFECTIONS. nothing is met with except serous effusion, in no great quan- tity, in the ventricles, or only on the surface of the brain. A third is seized in the same manner, and dies, after lying for a considerable time in a state of coma, from which nothing can rouse him for an instant; and on the most careful examination, we cannot detect in his brain the smallest deviation from the healthy structure. These facts have not escaped the observation of patholo- gists at various periods, and much difficulty was experienced in accounting for them upon the old doctrine of compression of the brain. Hence arose many speculations in regard to those cases in which no morbid appearance was met with on dissection, or none that was considered adequate to account for the disease. In a remarkable case of this kind, which occurred to Willis,* he supposes that the animal spirits were suddenly extinguish- ed or suffocated by certain malignant or narcotic particles.— Seelmatter ascribes the affection to a sudden relaxation of the nerves : Nicolai, to a spasm of the meninges ; and Lecat and Weikard to a spasm of the nerves and vessels of the brain.— Kortum endeavours to reconcile the discordant opinions of his predecessors, by referring all these cases to a new species of apoplectic affections, which he styles Apoplexia Nevosa. Up- on the same principle, other modifications of apoplexy have been contended for, which have been supposed to include these obscure and inexplicable cases, as the Apoplexia Con- vulsiva, and Apoplexia Hysterica of Burserius, Tissot, and other writers. Tissot mentions a woman, who, after com- plaining for sometime of headach, was attacked with a great and sudden increase of pain, accompanied by loss of sleep, and died in a short time. On dissection no morbid appear- ance could be detected. A young woman, mentioned by the same writer, having, during the flow of the menses, suffered from a fright, the discharge stopped, and she became liable to frequent leipothymia. After suffering from this and various other symptoms for several months, she fell into . a profound sleep, from which nothing could rouse her; this continued four days; she then came out of it and appeared to be reco- vering, when, after several days, she was seized with severe headach, anxiety, and convulsions, and died. No morbid ap- pearance could be detected in any of the viscera. Lecat at- * Willis De Anima Brutorum, part ii,.275. APOPLECTIC AFFECTIONS. 167 taches much importance to a case which occurred to him, in which, after fatal apoplexy, he found no morbid appearance except a small quantity of extravasated blood, not exceeding a tea-spoonful. This, he contends, could not account for the disease upon the principle of pressure, but was to be consi- dered as an effect, rather than a cause, of that spasm of the vessels, which he conceived to be the proximate cause of apo- plexy. This explanation did not satisfy his contemporaries, and various doctrines were brought forward to account for this form of the disease. Some maintained that the me- dullary substance of the brain is much more susceptible of compression than the cineritious; but the prevailing opinion was, that there are certain parts of the brain, where, by re- tarding the course of the animal spirits, slight causes of com- pression are capable of producing the most urgent symptoms. Hence arose a new and extensive controversy respecting the origin and progress of these animal spirits, and the course by which they make their exit from the brain. This important function was by one assigned to the acqueduct of Silvius ; by another, to the fourth ventricle; by a third, to the infundibu- lum; by a fourth, to the choroid plexus and straight sinus ; and fatal apoplexy was supposed to be produced by very slight causes, existing at these particular parts, and even by causes so minute as altogether to elude observation. From the number and variety of these speculations, we perceive the difficulties which attend the pathology of apoplexy, and learn the important fact, that apoplexy has, by extensive observa- tion, been ascertained to be fatal without any morbid appear ance, or with appearances so slight as to be altogether inade- quate to account for the disease. The most simple illustration of the apoplectic state, is de- rived from those cases in which it is distinctly traced to an external cause, and ceases when that cause is removed. A boy, mentioned by Zitzilius, had drawn his neckcloth remark- ably tight, and was whipping his top, stooping and rising al- ternately, when, after a short time, he fell down apoplectic.— The neckcloth being unloosed, and blood being drawn from the jugular vein, he speedily recovered. Strangulation, when the neck is not dislocated, appears to be simply apoplexy.— A man brought after execution to Sauvages, was recovered by three bleedings, and sat up and talked, his breathing and de- glutition being natural. After a short time the part of his neck where the cord had been applied began to swell, so as evi- 168 VARIOUS FORMS OF THE APOPLECTIC ATTACK. dently to impede the circulation in the veins of the neck: he then became drowsy, his pulse and respiration slow, without dyspncea, and in a few hours he died apoplectic. A woman, mentioned by Wepfer, recovered after execution under the same treatment. After her recovery she was for some time affected with vertigo, which subsided gradually. To cases such as these, we may add the numerous examples, in which persons fall down suddenly in a state of perfect apoplexy, and very speedily recover under the appropriate treatment, without re- taining any trace of so formidable a malady. The apoplectic attack, as it occurs in such examples as these, must be supposed to depend upon a cause which acts simply upon the circulating system of the brain, producing there a derangement which takes place speedily, and is often almost as speedily removed. What the precise nature of that derangement may be, is a point of the utmost difficulty to de- termine, and perhaps we have not data upon which it can be determined by legitimate induction. The subject leads to speculations of a very interesting kind, but it must be confess- ed that they are in themselves in a great measure hypotheti- cal, and that their application to the phenomena of apoplexy is also conjectural in a very great degree. They may be wor- thy of some attention, but must be kept entirely distinct from our present course of inquiry, in prosecuting which, I shall now take a general view of the principal varieties of symp- toms which occur in the attack of apoplexy. The apoplectic attack is generally preceded by symptoms in- dicating some derangement of the circulation in the brain.— The most remarkable of these are the following; headach, gid- diness, sense of weight and fulness in the head, violent pulsa- tion of the arteries, and confused noises in the ears. These symptoms are often accompanied by epistaxis, which may give a partial and temporary relief; by loss of recollection, and incoherent talking, resembling slight intoxication ; by af- fections of the sight, double vision, and temporary blindness ; by drowsiness and lethargic tendency. We also frequently observe indistinct articulation, and other partial paralytic af- fections. These are sometimes confined to one limb, or part of a limb ; sometimes affect the eyelids, producing inability either to shut the eye or to open it; and frequently impair the muscles of the face, producing a slight distortion of the mouth. These symptoms, and others of a similar Jand, mark VARIOUS FORMS OF THE APOPLECTIC ATTACK. 169 the tendency to the apoplectic state, and often appear for a considerable time before the attack actually takes place. The attack itself occurs chiefly under three distinct forms, which it is of importance to distinguish from each other. I. In the first form of the attack, the patient falls down sud- denly, deprived of sense and motion, and lies like a person in a deep sleep ; his face generally flushed, his breathing ster- torous, his pulse full, and not frequent, and sometimes below the natural standard. In some cases convulsion occurs, in others, rigid contraction of the muscles of the extremities ; and sometimes contraction of the muscles of the one side, with re- laxation of the other. In this state of profound stupor, the patient may die after various intervals, from a few minutes to several days; or he may recover perfectly, without any bad consequence of the attack remaining; or he may recover from the coma, with paralysis of one side. This paralysis may dis- appear in a few days, or it may subside gradually, or it may be permanent. Other functions, as the speeeh, may be affect- ed in the same manner, being speedily or gradually recovered, or permanently lost; and recovery from the apoplectic attack is sometimes accompanied by loss of sight. II. The second form of the disease begins with a sudden attack of pain in the head; the patient becomes pale, sick, and faint; generally vomits, and frequently, though not al- ways, falls down in a state resembling syncope ; the face pale, the body cold, and the pulse very feeble. This is sometimes accompanied by slight convulsion. In other cases, he does not fall down, the sudden attack of pain being only accompanied by slight and transient loss of recollection. In both cases he generally recovers in a few minutes from the first effects of the attack, is quite sensible and able to walk, but continues to complain of headach ; after a certain interval, which may vary from a few minutes to several hours, he becomes oppressed, forgetful, and incoherent, and then sinks into coma, from which he never recovers. In some cases paralysis of one side occurs ; but in others, and I think the greater proportion of this class, no paralysis is observed. III. In the third form, the patient is suddenly deprived of the power of one side of the body, and of speech, without stu- por ; or if the first attack be accompanied by a degree of stu- 22 170 CASES PRIMARILY APOPLECTIC. por, this soon disappears; he seems sensible of his situation, and endeavours to express his feelings by signs. In the far- ther progress of this form of the disease great variety occurs. In some cases, it passes gradually into apoplexy, perhaps af- ter a few hours ; in others, under the proper treatment, the pa- tient speedily and entirely recovers. In many cases the reco- very is gradual, and it is only at the end of several weeks or months that the complaint is removed. In another variety, the patient recovers so far as to be able to speak indistinct- ly, and to walk, dragging his leg by a painful effort, and after this makes no farther improvement. He may continue in this state for years, and be cut off by a fresh attack, or may die of some other disease without any recurrence of the symptoms in his head. In n fifth variety, the patient neither recovers, nor becomes apoplectic ; he is confined to bed, speechless and pa- ralytic, but in possession of his other faculties, and dies gra- dually exhausted, without apoplexy, several weeks or months after the attack. These three forms of disease frequently pass into one ano- ther ; but they are very often met with, as they are here de- scribed, forming affections which differ remarkably from each other; and they appear very naturally to arrange themselves into the three classes which have been here referred to ;—first, those which are immediately and primarily apoplectic; se- condly, those which begin with a sudden attack of headach, and pass gradually into apoplexy ; thirdly, those which are distinguished by palsy, and loss of speech, without coma. SECTION I. OF THE CASES PRIMARILY APOPLECTIC. The apoplectic attack is a sudden deprivation of sense and motion, the patient falling down as in a profound sleep, the face being generally flushed, and the breathing stertorous. In tracing the farther history of such an attack, the following circumstances deserve our particular attention. I. In many cases the patient speedily and perfectly re- covers. SIMPLE APOPLEXY. 171 II. In many cases the disease is speedily fatal, and we find on inspection extensive extravasation of blood. III. In other cases which are fatal, generally after a longer interval, we find only a serous effusion, often in no great quantity. IV. In many fatal cases, no morbid appearance whatever can be detected after the most careful examination. Thus the disease, in a pathological point of view, again resolves itself into three very important divisions ;—apoplexy with extravasation of blood;—apoplexy with serous effusion ;— and apoplexy without any morbid appearance, or what I propose to call simple apoplexy. The latter affection leads to specu- lations of very great interest; for, the phenomena of the dis- ease appear fully to establish the important fact, that there is a modification of apoplexy depending upon a cause of tempo- rary nature, without any real injury done to the substance of the brain; that the condition upon which this attack depends may be removed almost as speedily as it was induced ; and that it may be fatal without leaving any morbid appearance in the brain. As one of the terminations of the apoplectic attack, I have mentioned extensive extravasation of blood; but, in point of fact, it will be found that this is not a common termination of those examples which are immediately and primarily apoplec- tic. The cases which terminate in this manner, in general belong to another class already referred to, and to be afterwards particularly described, which begin with a sudden attack of violent headach, and pass into coma more gradually. The remarks to be offered under this section, therefore, will be confined to the two other forms of the disease, which seem to be nearly allied to each other, namely, apoplexy with- out any morbid appearance, and apoplexy with serous ef- fusion. R I.__Apoplexy without any morbid appearance, or SIMPLE APOPLEXY. When a person previously in perfect health falls down suddenly deprived of sense and motion, and dies after lying for a certain time in a state of apoplexy; and when, on the inspection of such a case, we cannot discover in the brain any 172 SIMPLE APOPLEXY. satisfactory deviation from the healthy structure, this is the affection which I propose to call simple apoplexy. I abstain at present from any speculations in regard to the nature of this remarkable affection, and shall confine myself to a state- ment of facts calculated to establish its existence as a disease of the brain, which may in this state be fatal. Case XCVII.—A woman aged about 30, of a full habit, some years before her death had been affected with symptoms in the head, accompanied by impaired speech, and partial loss of recollection. Some effects of this attack had continued for a considerable time, especially in her speech, but by degrees she had perfectly recovered, and enjoyed excellent health for a long period preceding the attack now to be described. She was stooping over a washing tub, when she was seized with a violent fit of sneezing; she almost immediately became in- sensible, and would have fallen down had she not been ob- served and supported by some persons standing by her, who carried her to bed in a state of perfect apoplexy. All the usual remedies were employed in the most active manner without the least effect in alleviating any of the symptoms— she lay with all the symptoms of the most perfect apoplexy, and died on the following day. On inspection, no vestige of disease could be discovered in the brain, or in any other organ. Case XCVIII.—A gentleman aged 24, had been observed for some days to be dull and drowsy, and he frequently com- plained of his head. Not having appeared at his usual time one morning, his friends went into his room, and found him lying across his bed, half dressed, in a state of perfect apo- plexy. The attack was evidently recent; and it was sup- posed that he had been seized while he had stooped over his basin in washing. His face was rather livid, his breathing stertorous, his pulse slow, and of good strength. All the usual remedies were employed with assiduity, but through the day there was no change in the symptoms. In the course of the night he recovered considerably, so as to know those about him; but in a short time after he relapsed into coma, and died early on the following day, little more than twenty-four hours after the attack. Inspection.—There was a slight turgescence of the vessels on the surface of the brain; no other appearance of disease SIMPLE APOPLEXY. 173 could be detected after the most careful examination. All the other viscera were in a healthy state. The following very important case I received from my friend, the late Dr. Duncan ; it occurred under his care in the Clini- cal Ward, in May, 1829. Case XCIX.—A man aged 54, of a plethoric habit and short necked, was admitted into the Clinical Ward on 30th May. He was in a state of nearly perfect coma, speechless, and with palsy of the right side, to such an extent that even the intercostal muscle of that side did not act. The leg and arm of the left side were occasionally affected with convul- sive motions. Breathing stertorous—deglutition much im- paired. Pulse 74. The affection was of three days' standing, and had come on with vertigo—loss of vision—violent head- ach and vomiting. All the usual remedies were employed in the most judicious and active manner without benefit. On the first of June, there seemed to be a slight return of intelligence, but he soon relapsed into coma, and died on the 3d, without any change in the other symptoms. Inspection.—A most minute and careful examination was made of the brain, without discovering any appearance of dis- ease, except that the choroid plexus seemed rather darker than u$ual, and the basiler artery was diseased at one spot. By the side of the artery, there was a spot of the cerebral substance, no larger than a barley-corn, which appeared some- what softened, but even this Dr. Duncan considered as ex- tremely doubtful. These, I think may be considered as fair examples of sim- ple apoplexy in its idiopathic form; I add the following ex- amples of the affection supervening upon other diseases. Case C.—A lady aged 50, had been liable for many years to attacks of cough and dyspnoea, which were generally re- lieved by opiates and blistering. On the 20th of December, 1816, she was seized with one of these attacks in the ordina- ry form. On the 22d she was better, though her breathing was still considerably oppressed. On the morning of the 23d she complained of headach, and wished not to be disturbed. Soon after this she appeared to her family to fall into a sound 174 SIMPLE APOPLEXY. sleep; but some time after, it was found to be perfect apo- plexy, from which nothing could rouse her,-and she died about five o'clock in the afternoon. I saw her only an hour befoie her death; she was then in perfect coma, her lips livid, her breathing quick and oppressed, and her pulse frequent and feeble. Inspection.—On the surface of the brain the veins were turgid, and the substance when cut into, exhibited a remark- able degree of vascularity; there was no other appearance of disease. The lungs were distended, and much loaded with thin mucus, but their structure was tolerably healthy. The other viscera were sound. Case CI.—A lady aged 45, had for three months before her death been affected with the following symptoms,—nau- sea and a peculiar uneasy feeling about the stomach, particu- larly after meals ; a feeling of distention of the abdomen, cos- tiveness of the bowels, and anasarca of the feet and legs. The appetite was tolerable, and the pulse natural, but from being remarkably strong and active, she became feeble, sal- low, inactive, and listless. A variety of practice was employ- ed for three months with little benefit; the anasarca gradually extended ; effusion took place in the abdomen, and there was much reason to suspect that it had also taken place in the thorax; the pulse, however, continued of natural frequency and good strength. On the evening of the 18th of May, 1816, she was observed to talk hurriedly and incoherently. On the morning of the 19th, she was in a state of stupor, from which at first she could be partially roused; but soon after mid-day it increased to perfect coma. She then lay in a state of perfect apoplexy, with stertorous breathing and much moaning, the face rather pale, the pulse 72, and of good strength, and she died on the morning of the 20th. The catamenia had been regular, except at the last period, which should have happen- ed about the 12th of May. Inspection.—No disease could be detected in the head after the most careful examination. There was considerable effu- sion both in the thorax and the abdomen. In the heart there was considerable hardness about the root of the tricuspid valves. No morbid appearance could be discovered in the other viscera. I have already referred to various cases mentioned by the APOPLEXY WITH SEROUS EFFUSION. 175 older writers, in which apoplexy was fatal, without leaving any morbid appearance ; and others are related by later authors of undoubted authority. A man, mentioned by Dr. Stark,* after complaining of headach and giddiness, fell down in a state of insensibility, with some convulsion. He then lay in a state of profound apoplexy for forty-five hours, when he died. No morbid appearance could be discovered in the brain on the most careful examination. A young lady, mentioned by Dr. Powel, after appearing for one day very heavy and disposed to sleep, fell into a state of perfect coma, which was interrupted only by occasional attacks of general convulsion. Without any change in the symptoms, she died on the third day. After the most minute examination, no morbid appear- ance could be discovered in the brain. Andral has described several cases of complete and sudden attacks of apoplexy, in which nothing could be discovered but slight appearances of increased vascularity on parts of the brain. One of them, which was fatal in two days, was accompanied by hemiple- gia. Dr. Bright has also described several cases, chiefly com- plicated with diseases of the lungs, in which there were strong- ly marked symptoms of oppressed brain, while nothing was to be discovered on dissection but some appearances of in- creased vascularity. Similar cases are related by other wri- ters, and, upon the whole, I think we have sufficient ground for stating it as a fact, that there is a modification of apoplexy which is fatal, without leaving any morbid appearance that can be considered as accounting for the symptoms. § II.—Apoplexy with serous effusion. Case CII.—A gentleman aged 80, but vigorous and active, and of rather a spare habit, about the 9th of June, 1813, be- gan to be affected with loss of recollection, indistinctness of speech, and flushing of the face. He appeared to have at times a weakness of the right arm, being observed occasion- ally to drop things from the right hand, but he did not admit that he felt any weakness of it. He complained neither of headach nor giddiness, but said he was weak, and did not feel himself right; the pulse was natural, and of good strength. After a bleeding from the arm, followed by purgatives and a * Works of Dr. VVm. Stark, page 73. 176 APOPLEXY WITH SEROUS EFFUSION. regulated diet, he seemed to be much improved; he had in a great measure recovered his recollection, and had lost the flushing of his face; and his speech was much more distinct. He walked out regularly, and his step was firm and vigorous. Soon after, however, he began to have a recurrence of confu- sion of thought, particularly on the 27th, when, in endeavour- ing to write a letter, he was obliged to relinquish the attempt. He complained that he could not make sense of it, nor spell the words; the writing was scarcely legible, and the lines were very crooked. On the 28th he seemed much better. On the following night he slept ill; got up about four o'clock in the morning, and said he felt restless and uneasy; he walked about his room for sometime, and then returned to bed. Hav- ing soon after this become quiet, his family did not disturb him till between eight and nine o'clock, when he was found in a state of perfect apoplexy, his pulse 80 and full, the ap- pearance of the countenance natural; he was incapable of swallowing, and in a state of complete insensibility, except that he occasionally moved his right hand. He was largely bled, after which he became exceedingly pale, and the pulse continued for a considerable time very weak, but without the smallest abatement of the coma. The other usual remedies were then employed without any benefit. In this state of per- fect apoplexy he lay for seven days, during which time there was very little change in the symptoms. He frequently moved his right arm and leg, but not the left; he occasionally scratch- ed a herpetic eruption which was on the thigh, and several times moved his night-cap. Once or twice he was observed to open his eyes slightly for a few seconds ; the pupil was na- tural, and contracted when a candle was brought near it. He passed his urine in bed. He never swallowed a drop of any thing. His pulse at first varied from 80 to 100, but afterwards rose to 120. In this state of perfect apoplexy he died on the 5th of February. A few days before his death, a gland- ular swelling appeared on his neck, from which he evident- ly felt pain, as he drew away his head when it was touched. Inspection.—A good deal of fluid escaped when the cra- nium was opened; there was considerable effusion under the arachnoid, and in the ventricles; the quantity collected was probably from three to four ounces. No other morbid appear- ance could be detected in any part of the brain. Case CHI.—A gentleman aged 70, of a florid complexion, APOPLEXY WITH SEROUS EFFUSION. 177 but rather infirm in his limbs, had suffered repeated attacks of Joss of recollection, which were said by his family to resemble fainting fits. At the commencement of the illness of which he died, he fell down suddenly deprived of sense and motion. After some time he recovered from this state of perfect insen- sibility, but his speech was now inarticulate; he had lost the power of his limbs, and his right eye was distorted outward. He was then confined to bed; at times incoherent, at other times more distinct, but always much oppressed, bordering upon coma; his speech continued very inarticulate, and his pulse was generally about 100. His strength sunk gradually, without any particular change in the symptoms ; and he died at the end of five weeks. Inspection,—The ventricles of the brain were found distend- ed with colourless fluid, and there was a considerable quanti- ty under the arachnoid. There was no other morbid appear- ance. Case CIV.—A man aged 41, of a very full habit, had been for some time affected with cough, dyspnoea, and anasarca of the legs, when he became one day suddenly incoherent, and soon after fell into coma. His breathing was much oppressed ; his face livid and turgid ; the pulse somewhat frequent. The coma was of that kind out of which he could be roused with difficulty so as to answer questions slowly, and heavily, and often incoherently. He died on the 3d day. Inspection.—Much fluid was found in the ventricles of the brain. The lungs were much loaded with blood, and there was considerable effusion in the cavity.of the pleura. In the heart the foramen ovale was open, of the size of a goose- quill. In concluding this part of the subject, I shall only add the following remarkable case, for which I am indebted to Profes- sor Turner, of extensive effusion in the cranium without any apopletic symptom. Case CV.—A gentleman aged about 70, a man of talent and of genius, had been valetudinary and hypochondriacal for upwards of 30 years, having been affected with a variety of uneasy sensations in the stomach, as indigestion, a sense of tightness across the lower part of the abdomen, and occasion- ally attacks 6i dysuria. In the beginning of 1817, he became 178 APOPLEXY WITH SEROUS EFFUSION. feeble, listless, and unable for any exertion either of body or mind: during the day he was drowsy, but his nights were restless and feverish. His countenance was pale and sallow; his pulse from 76 to 84; his tongue slightly loaded; his bowels generally costive, but easily moved by medicine, the operation of which was sometimes followed by diarrhoea. A variety of remedies were employed without benefit. He pass- ed the summer without improvement, and in the winter his complaints were aggravated. They consisted as formerly of heaviness, feebleness, and want of sleep, to which were now added a troublesome cough, and constant pain in the lower part of the abdomen, with strangury. His appetite failed ; his pulse increased in frequency ; and he became daily more and more feeble and emaciated. In the beginning of March, 1818, he was confined to bed; his strength then sunk gradu- ally, and he died on the 14th, having retained his memory and all his faculties entire till within a few hours of his death. He had never complained of headach or giddiness, and never had any paralytic or convulsive affection. Inspection.—A copious effusion of transparent fluid was found over the whole surface of the brain under the arachnoid membrane, which, in various places, particularly at the poste- rior part, elevated that membrane in the form of small blad- ders, and separated some of the convolutions from each other, so as to form depressions on the surface of the brain. The ventricles were also distended with fluid, but not much en- larged. The brain was in other respects sound ; the viscera of the abdomen were healthy. The bladder was contracted and thickened, but there appeared to be no disease of the pros- tate gland or the urethra. In the former part of this work, I have referred to several cases in which extensive effusion was found in the brain, without any apoplectic symptoms. The fluid in one of them amounted to eight ounces, and several other cases of the same kind are on record. Dr. Marshall mentions a maniac, who died of mortification of his feet; a few hours before death, he became perfectly rational, yet effusion was found both on the surface of the brain and in the ventricles, amounting to more than a pound. The apoplectic cases in which we find only serous effusion, constitute that modification of the disease which has been called serous apoplexy. In regard to this affection, or rather OF THE TERM SEROUS APOPLEXY. 179 to this mode of expression, I submit the following observa- tions. I. The distinction which has been proposed betwixt san- guineous and serous apoplexy, is not supported by observation. The former is said to be distinguished by flushing of the coun- tenance and strong pulse, and by occurring in persons in the vigor of life; the latter by paleness of the countenance and weakness of the pulse, and by affecting the aged and infirm; and much importance has been attached to this distinction, upon the ground, that the practice, which is proper and ne- cessary in the one case, would be improper or injurious in the other. I submit that this distinction is not founded upon ob- servation ; for, in point of fact, it will be found, that many of the cases which terminate by serous effusion, exhibit, in their early stages, all the symptoms which have been assigned to the sanguineous apoplexy ; while many of the cases, which are accompanied by paleness of the countenance and feeble- ness of the pulse, will be found to be purely sanguineous ; and one modification of the disease in particular will be described, in which these symptoms are very strikingly exhibited, while the disease is found to be sanguineous apoplexy in its most hopeless form. Portal has described a series of cases which afford the same result; of three, which presented all the symp- toms of serous apoplexy, one was saved by repeated bleeding, and in the other two which were fatal, there was found ex- tensive extravasasion of blood. Case CI., lately described, forms a remarkable addition to these observations. If any case would be confidently considered as serous apoplexy, this was such. Dropsical effusion had existed in the body for months; and in defiance of every remedy, it had been pro- gressively gaining ground. There were symptoms indicating its existence both in the thorax and in the abdomen ; the patient then became comatose, with pale countenance, and died ; but though dropsy was found in the othei* cavities, none could be detected in the brain. II. In other parts of the body, serous effusion is very sel- dom a primary disease ; it arises as a result either of inflam- matory action, or of impeded circulation, and takes place slowly, not accumulating at once in such quantity as to induce urgent symptoms. It is, therefore, in the highest degree im- probable, that it should occur in the brain as a primary disease, land accumulate with such rapidity as to produce the symp- toms of an apoplectic attack. 180 GENF.RAL CONCLUSIONS- III. The quantity of fluid effused bears no proportion to the degree of the apoplectic symptoms. We find it in small quantity though the apoplectic symptoms had been strongly marked and long continued ; we find it in large quantity when the symptoms have been slight; and, finally, we find most extensive effusion in the brain where there have been no apo- plectic symptoms at all. The direct inference from these facts is, that in the cases of apoplexy with effusion, the pre- sence of the fluid cannot be considered as the cause of the apoplectic symptoms. The facts which have been related in this section appear to warrant the following conclusions. 1. There is a modification of apoplexy, which is fatal with- out leaving any morbid appearance that can be discovered in the brain. 2. There is another modification, in which we find serous effusion, often in small quantity. 3. The cases which are referable to these two classes, are not distinguished from each other by any such diversity of symptoms as can be supposed to indicate any essential differ- ence in their nature. 4. Without any apoplectic symptoms, we find serous effu- sion in the brain in an equal or in a greater quantity than in the cases of the second modification. 5. It is therefore probable, that in these cases the effusion was not the cause of the apoplectic symptoms. 6. It is probable, that the cases of the first modification depend upon a cause which is entirely referable to a de- rangement of the circulation in the brain distinct from inflam- mation. 7. It is probable, that the cases of the second modification are, at their commencement, of the same nature with those of the first; and that the serous effusion is to be considered as the result of that peculiar derangement of the circulation, which constitutes the state of simple apoplexy. In other words, it is probable, that the affection which has been called serous apoplexy is to be considered as simple apoplexy termi* nating by effusion. APOPLEXY WITH EXTRAVASATION. 181 SECTION II. OF THE CASES OF THE SECOND CLASS NOT PRIMARY APO- PLECTIC. The cases to be described under this section differ remark- ably from those which are properly styled apoplexy. They are not at first apoplectic ; or, if there be at the very first at- tack loss of sense and motion, this state is recovered from in a few minutes, or perhaps seconds, without any remedy. The prominent symptom, at the commencement of the disease, is a sudden attack of violent headach, the patient often starting up and screaming from the violence of it. Sometimes he falls down pale, faint and exhausted, often with slight convulsion, but recovers from this state in a very short time. In other cases he does not fall down, but feels a sudden and great uneasi- ness in his head, generally with paleness, sickness, and often vomiting. The first attack being so far recovered from that the patient is often able to walk home, the symptoms go on under various modifications. The fixed pain in the head ge- nerally continues, often referred to one side of the head; and generally there is vomiting. The patient continues for some time, perhaps an hour or two, cold and feeble, with cadave- rous paleness of the countenance; his pulse weak and gene- rally frequent. He is quite sensible, but oppressed. By de- grees he recovers heat and the natural appearance of the coun- tenance, and the pulse improves in strength. The face then becomes flushed; he is more oppressed ; he answers questions slowly and heavily; and at last sinks into coma, from which he never recovers. The period occupied by these changes varies exceedingly in different cases. In one case to be de- scribed, there intervened, from the first attack to the com- mencement of coma, 5 hours; in a second, 12 hours; in a third, 3 days; and, in a fourth, not more than 15 or 20 minutes. Death followed the appearance of coma in the first of these cases in 7 hours, in the second in 32 hours, and in the third in two days. Other varieties occur which will be exemplified by the cases. Sometimes the coma follows so speedily, that the case closely borders upon the attack of simple apoplexy. 182 APOPLEXY WITH EXTRAVASATION, But I think there is almost always a certain interval of sense, generally with violent complaint of pain, and not that imme- diate and complete loss of sensibility which occurs in what may be strictly called the apoplectic attack. In Case CXL again, after the first attack there was an interval of a fortnight, without any urgent symptom; the complaint then returned, and was speedily fatal. In Case CXII., which seems to be- long to this class, after the coma had continued for three days, there was a complete recovery from it, succeeded by maniacal delirium. This, after seven days, was again followed by coma, which in three days more was fatal. In Case CIX. there was also, after evacuations, a temporary recovery from the coma, about 12 hours after its appearance, and 20 hours be- fore death. As far as my observation ^extends, the cases which belong to this class are generally fatal. They form a modification of the disease, remarkably different from the simple apoplectic state ? and, on inspection, we find none of those varieties and ambi- guities which occur in the apoplectic cases, but uniform and extensive extravasation of blood. From the whole history of them, I think there is every reason to believe, that they de- pend upon the immediate rupture of a considerable vessel, without any previous derangement of the circulation, the rup- ture probably arising from disease of the artery at the part which gives way. At the moment when the rupture occurs, there seems to be a temporary derangement of the functions of the brain, but this is soon recovered from. The circu- lation then goes on without interruption, until such a quan- tity of blood has been extravasated as is sufficient to produce coma. In their whole progress, these cases are strictly ana- logous to those of extravasation on the surface of the brain, from external injuries. The patient recovers from the imme- diate effects of the injury, walks home, and after some time, perhaps an hour or two, becomes oppressed and at last coma- tose^ The extravasated blood being in this case removed by the operation of the trephine, the coma disappears. The va- rieties of the symptoms which occur in this form of the dis- ease, are such as we might expect upon this view of the na- ture of the affection. In some cases it is probable that the extravasation goes on progressively, until such a quantity has been accumulated as is sufficient to produce the fatal coma. In others there is reason to believe that soon after the rupture has taken place, the haemorrhage is stopped by the formation. APOPLEXY WITH EXTRAVASATION. 183 of a coagulum, and after a considerable interval bursts out afresh and is fatal. This probably occurred in Cases CX. and CXI.; and in such cases, the two extravasations can sometimes on inspection be distinguished from each other by their appearance. In other cases, again, the second extrava- sation takes place in another part of the brain; and this pro- bably occurred in Case CXII. In this case the temporary re- covery from the coma was remarkable—the apoplectic state having taken place two hours after the attack, and having continued for three days. At that time, it is probable, the evacuations employed had the effect of restoring the circula- tion, which then went on in a very imperfect manner, until it was again interrupted by the fresh extravasation. The rapidi- ty with which the disease advances, in cases of this class, will of course depend in a great measure upon the size of the ves- sel from which the haemorrhage has taken place. In some cases, it will be seen to be very slow in its progress, and, in others, extremely rapid,—a very short interval taking place betwixt the first attack and the occurrence of perfect coma. Even in some of these cases, however, the patient survives a considerable time ; but in others the fatal event likewise takes place with very great rapidity. In some cases, again, the slowness with which the symptoms advance is very remarka- ble. A man, mentioned by Dr. Bright, first lost the power of the thumb and two next fingers of the left hand, but continued his work for four days, when he lost the use of the whole arm. A few days after this his leg became weak, and gradually completely paralytic. The case was fatal in a month, with- out perfect coma, and a coagulum was found in a cyst in the right hemisphere. The following selection of cases will illustrate the prin- cipal varieties of this very interesting modification of the disease. § I.—The coma rapidly supervening on the first ATTACK. Case CVI.—A clergyman aged 55, while delivering his sermon during the morning service of Sunday, 13th May, 1827, was observed to stop and put his hand to his head ; he then attempted to go on, but talked indistinctly, and had evi- dently lost his recollection ; he supported himself by grasping 184 APOPLEXY WITH EXTRAVASATION. the side of the pulpit. Assistance being immediately given him, he was taken out, and at this time was speechless and paralytic of the right side, but appeared to be sensible. He became rapidly more and more oppressed, and, in about twenty minutes from the commencement of the attack, had become en- tirely comatose. From the time when he was taken down from the pulpit, he was pale and cold, and his pulse extremely fee- ble ; and this state continued when I saw him, about an hour after the attack ; so that, though a vein was opened, very lit- tle blood could be obtained. Gradually the circulation rallied, and, in another hour, a full bleeding was obtained without any relief. All the other usual remedies were employed with- out benefit. From the time when the coma took place, there never was the slightest abatement of it; he lay with his eyes shut, his countenance pale and sallow, but placid and without distortion,—his pulse weak, the power of swallowing lost, the breathing at first stertorous, afterwards slow and oppressed. He lived in this state till Monday at mid-day, about twenty- four hours after the attack. Inspection.—There was extensive extravasation of blood in the left ventricle, which had passed partly into the right by laceration of the septum. It seemed to have made its way into the ventricle from the substance of the brain on the outer and anterior part, where there was a large, irregular, lacerated cavity, full of coagulated blood, and communicating with the ventricle; all the arteries of the brain were extensively os- sified. Case CVII.—A man aged 32, of a very full habit, while sitting by the fire on the evening of the 3d September, 1804, was suddenly seized with violent headach, followed by vomit- ing. After a few minutes he began to talk incoherently, and soon after fell down in a state of insensibility, accompanied by a slight convulsion. His face was extremely pale, his body cold, and his pulse scarcely to be felt. From this state, which resembled syncope, he passed gradually into the ap- pearance of apoplexy; and, three hours after the attack, his breathing was stertorous, the body of natural heat, the pulse 72 and of good strength. The face was still pale, he had frequent vomiting, and was incapable of swallowing, and there had been no diminution of the coma. He now lay in a state of profound coma, and died 29 hours after the attack, without any change in the symptoms, except that, during the last 12 APOPLEXY WITH EXTRAVASATION. 185 hours, the pulse varied from 100 to 112. Large bloodletting and the other usual remedies had been employed without the least benefit. Inspection.—All the ventricles of the brain were found.dis- tended with coagulated blood, which appeared to have burst into them from an irregular, lacerated opening in the substance of the brain. § II.--An INTERVAL OF PERFECT RECOLLECTION FOR SEVE- RAL HOURS BETWEEN THE ATTACK AND THE OCCRRENCE OF COMA. Case CVIII.—A gentleman aged 46, of short stature, full, flabby habit, and sallow complexion, a literary man, and very sedentary, while speaking in a public meeting on the 28th April, 1807, was seized with an uneasy sensation in his head, " as if his head would have burst," or " as if the brain had been too big for the skull." This feeling soon went off, and he continued his speech; but when he had finished it he left the room, and felt himself extremely unwell. He had cold shivering, nausea, and repeated vomiting; complained of headach and faintness ; his face was pale, and his pulse fee- ble. After some time he was able to walk home, where I saw him at nine, P. M., an hour or more after the attack. He then complained of violent pain in the right side of his head, which came on in paroxysms, and, in the intervals, he was much easier; he had nausea and repeated vomiting; he felt himself cold and faint; his face was pale and sallow; his pulse weak and rather frequent; he was quite sensible, but much oppressed, and answered questions very slowly. He was immediately bled from the arm, and, the pulse improving under the bleeding, it was continued to about 30 ounces, but without relief. He became gradually more and more oppress- ed, and. by 11, P. M., had sunk into coma, with stertorous breathing, and complete insensibility. In this state he con- tinued till six o'clock on the following morning, when he died. More blood had been taken from the temporal artery, and the other usual remedies employed without the smallest benefit. During the last six hours of his life, the pulse varied exceedingly, being sometimes slow and oppressed, sometimes frequent and full, and the transitions from the one state to the other were very sudden; a short time before death it was 24 186 APOPLEXY WITH EXTRAVASATION. strong and frequent. The pupil of the eye had retained its natural appearance, and no paralytic symptom was observed in any period of the attack. Inspection.—A large quantity of coagulated blood was found spread over the surface of the brain, under the dura mater, in all directions, chiefly on the right side. The origin of it was evidently from the substance of the right hemisphere, from which it had burst outwards by a large ragged opening. This opening communicated with a cavity in the substance of the hemisphere, which also was full of coagulated blood. Large coagula were likewise found under the base of the brain, around the cerebellum, and about the upper part of the spinal cord. In the ventricles there was about an ounce of serous fluid. Case CIX.—A lady aged 70, healthy and active for her years, had complained for a day or two of headach, but without being confined, or her health otherwise affected, till the even- ing of the 7th August, 1816, when she suddenly screamed out from violent headach, vomited, and then fell down in a state resembling syncope ; her face was extremely pale, and her pulse scarcely to be felt; and there was some slight appear- ance of convulsion. She recovered in a few minutes and went to bed. Through the night she was restless, vomited repeat- edly, and three or four times fell into a kind of fainting fit, of a few minutes duration. In some of these she was reported to have made a gurgling noise in her throat, and to have shown some convulsive motions of the arms; in the intervals she was quite sensible, and complained of headach. About eight o'clock in the morning of the 8th she sunk into coma. I saw her for the first time about ten; she was then completely co- matose ; breathing stertorous ; face rather pale ; pupil con- tracted ; pulse of good strength and a little frequent. The usual remedies were employed, and in the evening she had so far recovered, that, when raised up in bed, she took into her hand a glass containing some purgative medicine, and drank it. She seemed to attempt to speak, but could not; and soon after relapsed into perfect coma ; pulse at night 112; there seemed to be no paralysis. (9th) Continued in perfect coma, and died at four in the afternoon. Inspection.—In the anterior lobe of the right hemisphere of the brain, there was a cavity containing a mass of coagulated blood the size of a small hen's egg. From this cavity the APOPLEXY WITH EXTRAVASATION. 187 blood had forced a passage through the substance of the brain downwards, and had spread in all directions under the base of the brain, and upwards on both sides, betwixt the dura mater and the arachnoid, to such an extent, that portions of it were found on the upper surface of the brain on both sides of the falx. The substance of the brain surrounding the cavity, was soft and much broken down. There was nothing in the ventricles, and all the blood-vessels appeared remarkably empty. § III.—An interval of three days between the at- tack AND THE OCCURRENCE OF COMA. Case CX.—A gentleman aged 18, previously in good health, after using rather violent exercise in the forenoon, had returned home before dinner, and was sitting near the fire, when, without any warning, he started up, pushed his chair backwards with violence, exclaimed, " Oh my head !" and instantly fell on the floor insensible, and slightly convulsed.— I saw him within 10 or 15 minutes after the attack. By that time he had recovered his recollection, was sitting on a chair, and was quite distinct. His face was extremely pale, and his whole body cold and shivering : he complained of severe headach, and his pulse was weak and rather frequent. Blood- letting was immediately employed, and his pulse improved under it. It was repeated after a few hours, with the addi- tion of purgatives, and the other usual remedies. The cold- ness and paleness went off after some time, and he then com- plained only of severe headach, with a feeling of stiffness of his neck, and pain extending downwards along the cervical vertebrae ; his pulse was rather frequent and of good strength. He continued in this state for two days, the headach varying very much in degree, and frequently complained, chiefly of his neck ; his pulse was frequent, 120 or more, and of good strength ; the other functions were natural; he was quite dis- tinct ; had the use of all his limbs, and could get out of bed with little assistance, and sit up a considerable time. On the third day he began to be more oppressed, and a little confus- ed and forgetful; the other symptoms as before. On the fourth he sunk very gradually into coma, and died on the 5th. His pulse had continued from 120 to 140 ; there had been no paralytic symptom; but, on the fifth day, there was repeated 188 apoplexy with extravasation. convulsion. Bloodletting and all the other usual remedies had been emplyed without benefit. Inspection.—All the ventricles of the brain were complete- ly filled with coagulated blood. In the substance of the left hemisphere there was a cavity formed by laceration of the ce- rebral substance, filled also by the coagulum, and communi- cating with the ventricle. There was no other morbid ap- pearance. § IV.—The fatal coma occurring a fortnight after THE FIRST ATTACK. Case CXI.—A lady aged 56, enjoying good health, ex- cept occasional disorders in the stomach, on Tuesday, the 30th July, 1816, walked out in perfect health ; had gone but a very short distance, when she was seized with violent pain in the head and giddiness; soon after, she lost her recollec- tion and fell down. She very soon recovered her recollection, and was carried home, being unable to stand. She was then seen by Mr. White, who found her pale and faint; the pulse 70 and weak. She was a little incoherent, complained of se- vere headach, and had repeated vomiting. The vomiting re- curred frequently for two days, and then subsided ; the severe headach continued a week. During this period, she was ge- nerally confined to bed, but was sometimes able to sit up for a short time ; her face was pale ; her pulse from 70 to 76 and rather weak; she had some appetite, but bad sleep. She had no paralytic symptom, and made no complaint except of the constant pain of her head, which was always referred to the back part. At the end of the week, this pain became much less severe ; she then complained chiefly of pain in the back and limbs, and some dysuria ; her pulse was as formerly, and her mind entire. In this manner she passed another week, still confined to bed, but, towards the end of the week, she appeared to be much better. On Tuesday, 13th August, ex- actly a fortnight from the first attack, she was suddenly seized with violent pain in the head, chiefly referred to the back part of it; in less than an hour she became comatose ; and in three hours more was dead. The face had continued pale, and the pulse natural. I did not see this patient during her life, but was present at the examination of the body. Inspection.—In the substance of the. anterior lobe of the apoplexy with extravasation. 189 right hemisphere of the brain,t there was a cavity filled by a coagulum of blood, the size of a hen's egg. From this cavi- ty a lacerated opening led into the right ventricle, and all the ventricles were completely filled by coagulated blood. A thin stratum of blood was also found under the base of the brain, which seemed to have escaped from the ventricles, by forcing a passage under the posterior pillars of the fornix. Around the cavity in the right hemisphere, the substance of the brain was much softened and broken down. Both the kidneys were unusually vascular; about the right, there was a remarkable turgescence of veins, and an appearance of extravasated blood in the cellular membrane behind it. § V.—Two distinct extravasations. Case CXII.—A lady aged 40, of a spare habit, on the 15th May, 1811, at two o'clock, p. m., was suddenly seized with headach, accompanied by vomiting and diarrhoea: and at the same time began to talk incoherently. She continued to talk incoherently for two hours, and then sunk into coma, v I saw her at five ; she was then in a state of perfect coma; face pale ; the skin rather cold ; the breathing soft and natu- ral ; the pulse 65, soft and rather weak. During the after- noon, she had frequent vomiting and repeated diarrhoea ; no other change took place in the symptoms. Full bleeding was employed and a blister on the head; but she was incapable of swallowing. (16th, 17th, and 18th) She continued in a state of perfect coma; never opened her eyes nor showed the least sensibility, except that she drew away her arm with vi- olence when she was bled. She frequently moved all her limbs, and occasionally turned in bed. The pupil contracted a little when a candle was brought near it; the face was some- times a little flushed, but generally pale. The pulse was from 70 to 80, and of good strength. There had been no re- turn of the vomiting or diarrhoea after the 15th. Bleedings, both general and topical, were employed, with purgatives, &c. On the evening of the 18th, she came out of the coma rather suddenly, like a person awaking from sleep; looked around her, put out her tongue when desired, and took what was offered to her; she also talked a little, but incoherently. (19th and 20th) Much incoherent talking; appeared at times to understand what was said to her, but could give no account 190 APOPLEXY WITH EXTRAVASATION. of her feelings, only said, she was " very bad;" pulse from 70 to 80. (21st, 22d) Incessant talking and delirium; at times unmanageable and attempting to get out of bed ; at these times the face was flushed; at other times it was pale ; pulse varying from 90 to 120, weak and irregular; appeared to be blind, but had the use of all her limbs. (23d) Highly delirious and maniacal. (24th, 25th) Became calm and ma- nageable, and at times very weak. Pulse small and feeble, skin cold with a clammy sweat; appeared at times to see and to know those about her. (26th) Relapsed into coma; lay with her eyelids half shut, and the eyes distorted outwards; pulse from 80 to 100, and rather weak; face pale; was in- capable of swallowing. Continued in a state of perfect coma, on the 27th and 28th, and died in the afternoon of the 29th; —the pulse had continued about 90. Inspection.—All the ventricles of the brain were full of a dark-coloured fluid like coffee. In the substance of the right hemisphere, there was a cavity containing a coagulum of blood the size of a hen's egg. This cavity communicated with the ventricle, and the substance of the brain immediately surround- ing the cavity was very soft and much broken down. In the left hemisphere, at its upper and posterior part, there was a cavity the size of a large walnut. It contained a dark-colour- ed matter which appeared to be coagulated blood, but considera- bly changed in its appearance, being firmer in its texture than recent blood, and of a brownish colour mixed with portions of a lighter colour, which appeared to be diseased cerebral sub- stance. The substance of the brain surrounding this cavity was much softened and broken down. » Some part within the substance of the hemispheres, as in these examples, seems to be the most common origin of the haemorrhage in cases of this class. It is, however, sometimes found in the ventricles only, though more rarely. In the fol- lowing Case it was confined to the third and fourth ventricles. § VI.--THE EXTRAVASATION CONFINED TO THE THIRD AND FOURTH VENTRICLES, WITH REMARKABLE DISEASE OF THE ARTERIES OF THE BRAIN. Case CXIII.—A gentleman aged 55, of a thin spare habit, had, about six months before his death, an attack of hemiple- APOPLEXY WITH EXTRAVASATION. 191 gia, which, after the usual treatment, subsided gradually. On the 10th October, 1819, he complained suddenly after dinner of giddiness and sickness ; he went into another room, where he was found a few minutes after, supporting himself by a bed- post ; he was then confused and pale. Being put to bed, he soon became partially comatose, with muttering and frequent attempts to speak. I saw him more than an hour after the attack. He was then pale and sallow, pulse soft, languid, and rather slow. His eyes were open, but he did not seem to comprehend what was said to him. A vein was opened, which bled very little, the circulation appearing extremely languid. Some time after, he was bled again by Dr. Aitkin, when the blood flowed more freely, but without relief. He became completely comatose, and died about three o'clock in the morning. Inspection.—In the lateral ventricles there was a considera- ble quantity of bloody serum ; the third and fourth ventricles were full of coagulated blood. The arteries of the brain were in a great many places in a remarkably diseased state, being extensively ossified ; and there was in many places a singu- larly diseased state of the inner coat of the artery. It was much thickened, and of a soft pulpy consistence; and large portions of it could be squeezed out when a piece of the arte- ry was compressed between the fingers. In the cases now described, the haemorrhage appears to have taken place from the deep-seated arteries of the brain. In the two following cases, for which I am indebted to Dr. Barlow of Bath, and Dr. Hunter of this place, it appears to have been from the superficial vessels. § VII.—Extravasation on the surface of the brain. Case CXIV.—A gentleman about 63 years of age, tall and slender, and of temperate habits, was seized with apoplexy on the morning of the 2d of May, 1822. He was promptly re- lieved by bleeding, continued well through the day, and, on the morning of the 3d, appealed free from complaint. About two o'clock, however, there was a return of the attack, when he was again bled copiously, but without the effect of restor- ing consciousness. He was now seen by Dr. Barlow, and all the usual remedies were employed in the most active man- ner without relief. On the 4th, he was still comatose, and 192 APOPLEXY WITH EXTRAVASATION. continued so till ten o'clock at night, when consciousness re- turned, but continued only for a very short time. On the 5th, he had an interval of recollection which lasted three hours; and he was again sensible for about a quarter of an hour in the evening. He had a similar interval for about an hour and a half on the 6th, but on the 7th was comatose nearly the whole day. On the 8th, there was a slight return of con- sciousness in the morning ; and towards the evening, he was sensible for several hours. During these changes, the bowels had been fully opened, the pulse had continued about 72 and soft, and no paralysis of any limb had been observed. On the 9th, he was still lethargic, with some stertor; but, after topi- cal bleeding and the operation of a purgative, he was much relieved ; passed a quiet night, and on the morning of the 10th, he was quite sensible. It was now first observed that he had lost the sight of the right eye, which was distorted outwards. On the 11th, he lay with his eyes shut, but took food, and answered questions intelligibly when he was spoken to. On the 12th he was lethargic, but capable of answering questions when he was roused; and this state continued on the 13th. On the afternoon of that day, there was an increase of stupor, with difficulty of swallowing. He was again partially relieved by leeches, a purgative, and a blister to the neck, but the re- lief was only temporary. He became gradually more coma- tose, and died early on the 16th. Inspection.—A copious extravasation of. blood was found extended over the surface of the brain; it was closely adhe- rent to the dura mater, and could be peeled off like a mem- brane. The substance of the brain was healthy. There was no effusion in the ventricles. In the communication with which Dr. Barlow has favoured me in regard to this-singular case, he remarks, "the frequent returns of consciousness seemed to warrant a hope that no ir- remediable extravasation had taken place ; yet the event proved that extensive sanguineous effusionhad existed through- out. Was the lethargy owing to the extravasation ?—and, if so, why, under a permanently existing cause, was the effect so variable ?" These interesting queries I do not at present attempt to answer. Case CXV.—A man aged about 35, keeper of a tavern, and addicted to the constant use of ardent spirits, had been drinking to intoxication during the night betwixt the 12th and APOPLEXY WITH EXTRAVASATION. 193 13th July, 1816; and, about seven o'clock in the morning, was found lying in a state of violent convulsion. No account could be obtained of his previous state, except that, during the evening he had drunk a very large quantity of whisky, and that, when he was last seen about three o'clock in the morning, he was walking about his house, but unable to speak. He was seen by Dr. Hunter, at a quarter before eight. He was then lying on his left side, in a state of perfect insensi- bility, with laborious breathing; saliva was flowing from his mouth; his eyes were much suffused, and greatly distorted,— the cornea of both being completely concealed below the up- per eyelid; pulse 120, full and soft. While Dr. Hunter stood by him, he was again seized with convulsion ; it began in the muscles of the jaw^ which were drawn from side to side with great violence, producing a loud jarring sound from the grind- ing of the teeth. The spasms then extended to the body and extremities, which were first thrown into a state of violent ex- tension and then convulsed for one or two minutes ; they then subsided, and left him as before in a state of perfect insensi- bility. Similar attacks took place four times while Dr. Hun- ter remained in the house, which jtoas^ about half an hour; and he expired in another attack of the same kind about ten mi- nutes after. Bloodletting, and every other remedy that the time admitted of, were employed in the most judicious manner. Inspection.—On removing the skull cap an appearance was observed on the surface of the dura mater, of coagulated blood in small detached portions. These appeared to have been discharged from small glandular-looking elevations on the outer surface of the dura mater, which were very vascular, and highly gorged with blood. There were depressions on the inner surface of the bone,which corresponded with these bodies. On raising the dura mater, th£re came into view a coagulum of blood, covering and completely concealing the right hemi- sphere of the brain; it was about two lines in thickness over the middle lobe, and became gradually thinner as it spread over the anterior and posterior lobes, and dipped down below the base of the brain. The coagulum being removed, was found to amount to about 3, ounces. On the surface of the left hemisphere, the veins were turgid with blood ; on the sur- face of the right, they were entirely empty ; but the source of the haemorrhage could not be discovered. There was no fluid in the ventricles, and no other disease was discovered. The 25 194 APOPLEXY WITH EXTRAVASATION. stomach being carefully examined, was found to contain no- thing but air and some healthy mucus. The following case, for which I am indebted to Dr. Macau- lay, is altogether a remarkable one. It is the most rapidly fatal case of cerebral disease that has occurred to me. Case CXVI.—A woman aged 54, who had been for seve- ral years liable to headach, attended a crowded meeting on the evening of 25th June, 1829, and seemed in perfect health. Towards the conclusion of the meeting she uttered a loud and convulsive scream, and instantly fell down in a state of insen- sibility. She was immediately carried out and was seen by Dr. Macaulay, who happened to be present: he found her pale and totally insensible, and the pulse feeble : and within five minutes from the first seizure she was dead. Inspection.—The integuments of the head were much load- ed with blood. On removing the dura mater, there was a thin but very extensive appearance of extravasated blood, or rather ecchymosis, which covered nearly the whole surface of the brain. In the substance of the anterior lobe of the right he- misphere there was a coagulum of blood the size of a large bean. All the other viscera were examined in the most accu- rate manner, but nothing was discovered, except a tubercle on the liver, and a small spot of ossification on the abdominal aorta. When the disease takes place in the cerebellum, or below it, the symptoms appear to be more rapid in their progress than when it is in the substance of the brain : the two following cases will illustrate this modification of the disease; for the second of them I am indebted to the late Dr. Hennen. § VIII.—Extravasation in the cerebellum. Case CXVII.—A woman aged about 70, a midwife, of a1 full habit and short stature, while sitting by the bed of a lady whom she was attending, suddenly exclaimed, "I am gone!" and almost immediately fell down in a state of coma, with some vomiting. She lay in a comatose state, without any change in the symptoms for 40 hours, and then died. Inspection.—A coagulum of blood, the size of a pigeon's ■ APOPLEXY WITH EXTRAVASATION. 195 egg, was found in the right lobe of the cerebellum. There was no other morbid appearance. Case CXVIII.—A private in the 10th Hussars, of a spare habit, about a month before his death was attacked with a pain in the back of his head, for which a blister was applied, and the pain soon went off. On the 22d July, 1819, he was seized with giddiness and fell down; on being raised he vo- mited, and complained of violent headach and faintness, but was quite sensible ; he was very pale, and his pulse was slow and languid. Being carried to the hospital, he continued in the same state; asked for cold water, which he swallowed, and seemed relieved of the faintness, but continued very pale. In a few minutes his eyes became fixed; he drew deep inspi- rations, and in two minutes more was dead. From the mo- ment of seizure, he did not move either the upper or lower ex- tremities. Inspection.—Nothing unusual was discovered in the brain. On raising the tentorium, the vessels of the cerebellum ap- peared very turgid. On removing the cerebellum, a coagu- lum of blood of about two ounces was found under it, and surrounding the foramen magnum. § IX.—Extravasation in the substance of the tuber ANNULARE. Case CXIX.—A gentleman aged 37, had been for several months in bad health, being affected with occasional tightness of the chest and difficulty of breathing. He had also severe dyspeptic complaints, with occasional vomiting, a yellow tinge of his skin, and considerable uneasiness in the region of the liver. For these complaints he had been advised by his medical attendants in the north, to go to Cheltenham, and arrived in Edinburgh with that intention on 22d March, 1828. I saw him on the following day along with Mr. Wishart. We found his pulse frequent, his countenance sallow, and his ex- pression febrile and anxious. He complained chiefly of tight- ness across his chest, with some pain in the region of the liver. Respiration was very imperfect along the right side of the thorax, and there was some oedema of the legs. By topi- cal bleeding, purging, &c, he was considerably relieved; and on the 24th he expressed himself as feeling much better, but 196 APOPLEXY WITH EXTRAVASATION. his pulse continued frequent. On the morning of the 25th he was suddenly seized with giddiness, noise and confusion in his head, and numbness of the whole right side. He was op- pressed, but not comatose ; answered questions distinctly, but in a loud voice, and with a peculiar manner. He complained chiefly of noise in his head, of a tight and cramped feeling of his right arm and leg, with much prickling and loss of com- mand of the parts, but when desired to grasp another person's hand with his^ the muscular power did not seem to be dimi- nished. The expression of his countenance was vacant and fatuous : the eye was natural. The face was slightly distort- ed, and the speech was in some degree embarrassed. The pulse was 120. After large bloodletting and the other usual remedies, the symptoms gradually assumed a more favourable aspect, and, after four or five days, he was considered as being out of any immediate danger, though the effects of the attack were by no means removed. His pulse was now natural, his speech was distinct, and his mind entire; his sight was good, and the appearance of the eye natural, except a slight degree of paralysis of the upper eyelid of the right side. His breathing was easy, and he made no complaint, except of the tight and cramped feeling with numbness of the right arm and leg. His look, however, continued vacant and peculiar. His appetite and digestion were good, and his bowels easily regulated. He was improving in strength, and was able to be out of bed part of the day. This favourable state continued till the 14th of April, on which day he was found with a very frequent pulse, without any other change in the symptoms. This fe- brile state continued on the two following days with rapid failure of strength, and he died on the evening of the 16th. He continued sensible to the last, and during this febrile at- tack, he seemed to have acquired an increased command over the limbs of the affected side. About the commencement of his illness of 25th March, he complained of considerable uneasiness in passing his urine; for a day or two it was bloody, and there was a good deal of tenderness in the region of the bladder! After a few days this subsided, and he began to pass considerable quantities of puriform fluid of remarkable fetor, which subsided to the bottom of the chamberpot, after the urine had stood for a short time. This continued during the remainder of his life, though it had greatly diminished in quantity for several days preced- APOPLEXY WITH EXTRAVASATION. 197 ing the last febrile attack. The urine was in sufficient quan- tity and passed without difficulty. Inspection.—The brain and cerebellum were found in every respect in the most healthy state, and no vestige of disease was discovered until the cerebellum was separated from the tuber anulare. In doing so a cavity was exposed about the size of a large hazel nut, lined by a soft cyst, and full of dark, grumous blood of a firm consistence. This remarkable cavi- ty was formed partly in the substance of the tuber, and partly betwixt it and the base of the cerebellum. It was decidedly more to the left side than the right, and the surrounding sub- stance was softened, and tinged with dark red points, as if from injection of dark blood. There was effusion in the tho- rax to the amount of at least lb. ii. The right lung was con- tracted, and extensively hepatised ; the left was much loaded with sero-purulent fluid. The liver was very considerably enlarged and of a pale-ash colour and granular texture. The left kidney was pale, indurated, and tubercular. The inner surface of the bladder was deeply injected, and in several pla- ces showed distinct round ulcers about a quarter of an inch in diameter. § X.—Extravasation in all the ventricles and along THE WHOLE COURSE OF THE SPINAL CORD. The following case shows the most extensive extravasation of blood that has ever occurred to me. It is also remarkable from the period of life at which the affection took place, and its similarity in the symptoms to one of the common inflam- matory affections terminating by effusion. Case CXX.—A boy aged 9, previously in perfect health, awoke in the night of the 18th May, 1829, complaining of headach ; had vomiting and slight convulsion. On the 19th, he was seen by Mr. W. Brown, who found him still complain- ing of headach with occasional vomiting, but without any ur- gent symptom. Under the usual treatment the complaint seemed gradually to subside, and on the 25th he appeared to be entirely recovered. But on the afternoon of that day, he had a return of convulsion, and in the evening complained much of headach. Pulse 64. (26th and 27th) Said he was better, but seemed drowsy. Pulse slow. Bowels obstinate. 198 APOPLEXY with extravasation. —28th, had two attacks of convulsion, the second of which was very severe and continued for several hours, affecting chiefly the left side of the body. Pulse 130. On the 29th he was again better; but from this time he became gradually more and more drowsy, and at last comatose with squinting, and occasional convulsive motions of the limbs, and he died on the 3d of June. His death was preceded by severe con- vulsion of several hours duration. I saw him along with Mr. Brown from the 29th. Inspection.—The surface of the brain was healthy. The lateral ventricles were distended with dark bloody fluid, and each of them contained a mass of coagulated blood; that in the right was the size of a large walnut, the other smaller. The 3d and 4th ventricles were quite filled with coagulated blood in a very firm state, and from the bottom of the fourth ventricle, the coagulum was traced outwards and spread along the base of the brain and cerebellum, and around the medulla oblongata. The spinal canal being now laid open, the dura mater of the cord appeared remarkably distended, and the cord was found through its whole extent entirely enveloped by a very firm and uniform stratum of coagulated blood. The brain and cord were in their substance healthy, and the source of the haemorrhage could not be discovered. § XI.—Extravasation in a cyst, formed by separa- tion OF THE LAMINA OF THE DURA MATER, FROM RUP- TURE OF THE MIDDLE MENINGEAL ARTERY. The following remarkable case was lately communicated by Dr. John Gairdner, to the Medico-Chirurgical Society of Edinburgh, and will appear, in a more detailed form, in the next volume of their transactions. Case CXXI.—A man aged 48, about the 12th of Novem- ber, 1814, was assisting a neighbour to carry a heavy load to the top of a high stair, when he felt a sudden attack of head- ach. He was, from that time, troubled with headach and oc- casional giddiness, increased by stooping;—and, after these symptoms had continued rather more than a fortnight, he be- came sensible of some imperfection of vision. When seen by Dr. Gairdner on the 2d of December, he complained of vio- lent headach. Pulse 40, and feeble.—The pupils were at apoplexy with extravasation. 199 this time sensible to the light, but after a few days became insensible. He sunk very gradually into coma, without any other remarkable symptom, and died on the 13th. Inspection.—On the left side of the head, a cyst was found in the course of the middle meningeal artery, occupying the region of the lower part of the parietal and upper part of the temporal bone. It was formed by a separation of the laminae of the dura mater, and contained about four ounces of coagu- lated blood. The portion of the dura mater forming the cyst was considerably thickened and very vascular. There was a depression on the surface of the brain, corresponding to the cyst,—and the ventricles contained a considerable quantity of serous fluid. There was no other morbid appearance. The source of theghaemorrhage in cases of extravasation in the head appears t^te exceedingly various. I. The most common is probably the rupture of a vessel of moderate size in the substance of the brain, from which the blood bursts by laceration either into the ventricles, or to the surface, or in both these directions at once, as in a case de- scribed by Morgagni. It is in vain in general to attempt tra- cing it to particular vessels ; Dr. Cheyne was able to do so in some instances; but, in general, numerous vessels must be laid open by the extensive laceration, and hence, probably, the appearance which has been observed, as if the extravasation had taken place from various points at once. A case is de- scribed by Serres in which the rupture took place in the sub- stance of the pons Varolii; and from this the blood had burst forth into the occipital fossa.* II. The superficial vessels. This probably took place in the remarkable cases communicated by Dr. Hunter and Dr. Barlow. This appears to be the meningeal apoplexy of Ser- res. The blood seems in general to be accumulated betwixt the dura mater and the arachnoid ; and two cases of this kirrd have been described by Andral; but cases have been describ- ed by Fernelius and Tulpius, in which the blood appeared to be confined beneath the pia mater, and to have been discharg- ed from the retiform plexus of vessels at the base of the brain. In Case CXXXI., again, the cyst, which seemed to have con- * Annuaire Med. Chirurg. 200 apoplexy with extravasation. tained the extravasation, appeared to have been formed in the cellular tissue of the arachnoid itself. III. From ulceration and rupture of one of the principal arterial trunks. Dr. Mills has described a case in which the haemorrhage was distinctly traced to ulceration and rupture of the basilar artery; and a similar affection of the internal caro- tid is described by Morgagni and by Serres. IV. From the vessels of the choroid plexus, as in a case described by De Haen. This may probably be the source of haemorrhage in those cases in which it is confined to the ven- tricle, without any laceration of the substance of the brain. In Case CX1IL, it was confined to the third and fourth ven- tricles. Dr. Bright, also, has described a case which was fa- tal in twenty minutes, in which the extravasation, amounting to about three ounces, was confined to the ventricles, without any rupture of the cerebral substance. H^.supposes it to have proceeded from the vessels of the velum interpositum. V. Rupture of one of the sinuses, as in a case described by Dr. Douglas,* in which the left latteral sinus was ruptured. VI. From the rupture of small aneurisms in various parts of the cerebral vessels. In a case by Serres, such an apeu- rism occurred in the basilar artery, which, when it was dis- tended, was as large as a small hen's egg. A pound of blood had been discharged by the rupture of it. This man had been long subject to a feeling of weight in the head, and, according to his own statement, to an indescribable stupidity, which was much increased by bodily exertion, and by strong liquors. In the Archives Generales de Medecine, a case is described, in which apoplexy followed the bursting of a small aneurism in the circle of Willis; and Dr. Bright describes a case, which occurred in a lad of 19, from the rupture of a small aneurism of one of the smaller branches of the middle cerebral artery. VII. In the Medical and Surgical Register of the Hospital of New York, a very uncommon case is described by Dr. Watts, in which the haemorrhage took place betwixt the dura mater and the bone, from erosion of a vessel in connexion with caries of the inner surface of the parietal bone of the left side. The man was suddenly seized with hemiplegia of the right side, and died in five days. The carious spot on the inner surface of the bone was not so large as a sixpence. In Case CXXL, I have described a form of the disease, equally * Edin. Med. Essays and Observ. vol. vi. APOPLEXY WITH EXTRAVASATION. 201 uncommon, in which the extravasation took place, from rup- ture of the middle meningeal artery, in a cyst formed by sepa- ration Of the laminae of the dura mater. In the mbst common form of this affection, in which the haemorrhage proceeds from a vessel in the substance of the brain, I have supposed the rupture to take place from disease of the artery itself, without any relation to that congestive or haemorrhagic condition which seems to constitute the state of simple apoplexy. Such disease, accordingly, will be very generally found to exist in cases of this class. It consists in some instances of ossification of the arteries in various places, and in others, of that peculiar earthy brittleness, which Scarpa has described as leading to aneurism; and the canal of the artery will be found in many places to be considerably nar- rowed or contracted at the hardened parts, and sometimes en tirely obliterated. In other cases again, numerous branches of the principal arteries of the brain will be found to present a succession of small opaque osseous rings, separated from one another by small portions of the artery in a healthy state. This is a very common appearance in the brains of elderly people, and the rings are generally from half a line to a line in breadth, and are separated from each other by healthy por- tions of about the same extent. In some cases again the in- ner coat of the artery is much thickened, of a soft pulpy con- sistence, and very easily separated; so that, when a portion of the artery is compressed between the fingers, a considerable quantity of this pulpy matter is forced out. This was very remarkable in Case CXIII. In a case of apoplexy very ra- pidly fatal, which occurred to the late Dr. Duncan, and Mr. Wishart, they took particular notice of the remarkably dis- eased state of the arteries of the brain, which they describe as exhibiting every where the " earthy brittleness of Scar- pa." There is much reason to believe, that this diseased condi- tion of the arteries of the brain may give rise to a variety of complaints in the head; and that, after going on for a con- siderable time in this manner, it may at length be fatal by rupture. This appears to be probable from the history of many cases. I shall only give the following as an example. Case CXXII.—A gentleman aged about 50, was for seve- ral years affected with complaints in his head, which assumed a great variety of characters. He had at first attacks of gidr 26 202 apoplexy with extravasation. diness and headach, with loss of recollection and impaired speech. These occurred from time to time, and went off without leaving any bad consequences. After a year or two, the symptoms became more permanent, and he had violent paroxysms of pain, which at one time were much relieved by arsenic. He then had attacks bordering upon mania, with loss of recollection for several days. Afterwards he had epi- leptic attacks, alternating with these maniacal paroxysms. He next was affected with attacks of stupor of various dura- tion. The disease went on in this way for several years ; and he died at last in May, 1820, after an apoplectic attack which continued eight or nine days. Inspection.—Connected with the fatal attack, there was a coagulum of blood, the size of an egg, in the substance of the right hemisphere. The only other morbid appearance was a remarkably diseased state of the whole arterial system of the brain. It was most extensively ossified, with a thickened and very diseased state of the inner coat of the arteries, and partial separation of it from the other coats in many places. Scarcely any branch could be traced through the whole brain entirely free from disease. The vertebral arteries were also much affected, especially the left, which was much enlarged, and its coats thickened, ossified in spots, and brittle. The state of the arteries in such a case as this, with the par- tial separation of the inner coat, could not fail to be produc- tive of much disturbance of the circulation, and much derange- ment of the functions of the brain. Another case will be af- terwards mentioned, in which a similar disease appeared to have led to frequent paralytic attacks ; the patient died at last of gangrene of the toes. (Case CXXV.) See also the dis- ease in the basilar artery described in case XXXV., in which it was entirely obstructed and distended by a firm white mat- ter, without any appearance of blood. It appears that a disease somewhat similar occurs in the veins of the brain, as in the following remarkable case with which I have been favoured by Dr. Cheyne, of Dublin. Case CXXIII.—A lady aged 42, was of a melancholy temperament, and had been subject to headachs from early life. About ten years before her death, she lost her husband under circumstances of peculiar distress, and from that time confined herself to the house, and laboured under the greatest dejection of mind. She was liable to frequent attacks of bi- APOPLEXY WITH EXTRAVASATION. 203 lious diarrhoea, and her old headachs became more constant and more severe. In one of these attacks she became apoplectic, and died. Inspection.-^There was a turbid effusion betwixt the arach- noid and pia mater, and the whole surface of the brain was bloodshot. The venous system of the brain was diseased af- ter an unusual manner. There was a deposition of a firm yellowish-white substance between the lining and outer coat of the veins ; it was universal all over the brain, giving to the veins a mottled or rather ribbed appearance. The appearance of the whole of the arterial system was precisely the same as the venous, and both the arteries and veins were thicker but more fragile than usual. The medullary portion of the brain was more than usually vascular; on the inner side of the pos- terior horn of the left lateral ventricle, there was an irregular cavity about an inch in length and half an inch in breadth. The portion of the brain which formed the walls of the cavity was much diseased, soft and yellow; its structure was de- stroyed, and it was penetrated by a number of enlarged and unsupported vessels. The left choroid plexus contained an hydatid the size of a large pea. This important subject has been little investigated, but there seems every reason to believe that disease of the venous system of the brain may have a most extensive influence in the affections of that organ. Various examples of this class will be found in the preceding observations, particularly the complete obstruction of the lateral sinus which occurred in Cases IV. and V., and the remarkable disease of the veins on the upper surface of the brain in Case XXX. The subject is worthy of careful investigation, and promises important results. A lady, mentioned by M. Gendrin, having been exposed to mental agitation on the seventh day after accouchment, be- came insensible, and continued so for three quarters of an hour. On her recovery, she complained of acute pain in the left side of the head, which continued with little change for ten days, notwithstanding topical bleedings, and various other remedies. There was then a great and sudden increase of it, accompani- ed by pain in the left ear, and this was soon followed by pal- sy, first of the right arm, and soon after of the right leg. Three days after this, there was loss of speech with partial stupor, then convulsive attacks, and strabismus; and she died on the 17th day of the disease. On inspection, the middle cerebral 204 PARALYTIC CASES. vein on the right hemisphere, where it approached the longi- tudinal sinus, was f«ind very large and containing a puriform substance which entirely filled it: and the corresponding vein on the left side was in the same state. There was also ex- tensive disease of the longitudinal sinus, its cavity, for several inches, being entirely degenerated into an irregular cellular mass, infiltrated with purulent matter mixed with blood. In the posterior part of the left hemisphere, there was exten- sive ramollissement, mixed with purulent matter. The ven- tricles were empty. This affection is also described by Dr. Bright. In a child, aged 20 months, who died after an ill- ness of three weeks, with headach, squinting, and frequent convusion, he found all the larger veins running into the lon- gitudinal sinus, quite round and hard, being filled with a yel- low-coloured coagulum, as if they had been injected with wax. This appearance extended through one or two subdivisions in some parts, and the longitudinal sinus itself was found full of a coagulum, taking the exact form of the sinus, which seemed to be almost entirely composed of fibrin, with a little of the red blood in parts and cavities. There was effusion in the ventricles, and ramollissement in various parts of the brain. SECTION IIT. OF THE CASES OF THE THIRD CLASS, OR THE PARALYTIC CASES. Under this class I have included a description of cases which resemble each other in their symptoms only, but are found to differ most remarkably in the morbid conditions of the brain with which they are connected. We are not possessed of sufficient information to enable us accurately to discrimi- nate them from each other; and all that-we can attempt, at present, is to give a statement of the facts relating to them, under a simple arrangement. The leading phenomenon of this class is the paralytic at- tack without coma, or at least without that complete and per- manent coma which occurs in the former classes. Some of those cases, indeed, which begin as a paralytic attack, after a VARIOUS FORMS OF THE PARALYTIC ATTACK. 205 certain time pass into apoplexy, the paralytic attack being only the prelude to, or the first stage of the apoplectic; these of course belong to another class, particularly the second. The cases which I mean to include under this third class are those in which, either there has been no apoplexy, or the apoplectic state has soon passed off, leaving the paralysis as the more prominent and permanent character of the disease. The attack appears under various forms ; the most common of which is hemiplegia with loss of speech ; but in some cases the speech is not affected; while in others, the loss of speech is at first the only symptom. L~i some cases, again, one limb only is affected, which is most commonly the arm, though sometimes the leg. Numerous other modifications occur, as, palsy of one eyelid; or of the orbicularis of the eye; distor- tion of the eyes; double vision; twisting of the mouth, &c. Loss of the power of swallowing also occurs occasionally, though more rarely in the cases which do not pass into apo- plexy. The patient frequently appears quite sensible of his situation, and makes anxious attempts to express himself; generally understanding in a great measure what is said to him, and answering by signs. Sometimes, however, when he retains a partial power of speech, his answers are incohe- rent and unintelligible. In the farther progress of cases of this class, we observe remarkable varieties, which may be chiefly referred to the fol- lowing heads. I. Such an attack may be merely the prelude to the apoplec- tic, and may pass into it after a short interval. These cases belong chiefly to the second class. II. The attack may, under the proper treatment, pass off speedily and entirely, leaving, after a very short time, no trace of its existence. III. The recovery may be very gradual, the use of the affected limbs being restored after several weeks or months. IV. The palsy may be permanent; that is, the patient, af- ter a certain time, may recover so far as to be able to walk about, dragging his leg with a painful effort, and to speak very imperfectly ; and after this, makes no farther improve- ment to the end of his life, which may be protracted for many years. V. In a fifth variety the patient makes no recovery ; he is confined to bed, speechless and paralytic, but possessed of his other faculties in a considerable degree, and dies gradually 206 PARALYSIS WITH SEROUS EFFUSION exhausted, after several weeks or months; in some cases with- out coma, in others with coma for a few days before death. In endeavouring to investigate the morbid conditions of the brain which are connected with these varieties, we find consi- derable diversities, which, in a pathological point of view, may be referred to the following heads. I. Many of the cases appear to have a close analogy to sim- ple apoplexy ; and when they are fatal, present either no sa- tisfactory appearance, or only serous effusion, often in small quantity. II. Extravasation of blood of small extent, contained in de- fined cysts in the substance of the brain or under the mem- branes. III. Ramollissement of the cerebral substance. IV. Inflammation and its consequences. § I.—Paralytic cases, with serous effusion, or with SLIGHT MORBID APPEARANCES. When a paralytic attack of the most formidable appear- ance passes off speedily and entirely, without leaving any trace of disease, we may suppose that no very serious injury has been done to the substance of the brain ; and that the disease bears a close analogy to the affection which I have termed Simple Apoplexy ; or, in other words, that the cause had con- sisted of a state of the circulation of the brain, which is capa- ble of being speedily and entirely removed. Many cases again are fatal, and present, on dissection, only serous effusion, often in small quantity. A man, mentioned by Morgagni, had palsy of the right arm, and died apoplectic in two days. On dissection, no morbid appearance was discovered, except se- rous effusion, both in the ventricles and on the surface of the brain. Another had loss of speech, and palsy of the left side, and died comatose at the end of a month. Considerable ef- fusion was found on the surface of the brain, but very little in the ventricles. A third had loss of speech and palsy of the right side, then became comatose, and died in five days. The ventricles contained about two ounces of fluid ; there was also a good deal on the surface of the brain, which appeared to be most abundant on the right side. I have formerly given my reasons for believing, that serous effusion in apoplectic cases is not a primary disease but a ter- PARALYSIS WITH SEROUS EFFUSION. 207 mination of simple apoplexy; and I have described cases in which it existed to a considerable extent without paralysis.— In the cases, again, in which it has been accompanied by pa- ralysis, the quantity of fluid has borne no proportion to the symptoms, and has been equally distributed over the brain ; except in the case now quoted from Morgagni, in which too, it is worthy of remark, it appeared to be most abundant on the same side with the disease. From these considerations, I think we may conclude, that, in the cases now referred to, the effusion was not the cause of the paralysis, but the effect or the termination of a certain state of the circulation in a part of the brain, with which the paralysis had been connected from the first invasion of the disease. The whole phenome- na of palsy, do indeed bear evidence, that certain cases of it depend upon a cause, which is of a temporary nature, and ca- pable of being very speedily and entirely removed. We see hemiplegia take place in the highest degree, and yet very ra- pidly disappear; but the most singular circumstance, con- nected with certain cases of palsy, is, that we occasionally see it continue without any improvement for many weeks or months; and then, from some change which entirely eludes our observation, take a turn for the better, and very suddenly disappear. - I do not know to what class I ought to refer the following- case, but I shall introduce it here as the most remarkable ex- ample that has occurred to me, of long-continued palsy, with- out any satisfactory morbid appearance. Case CXXIV.—A gentleman aged 35, while standing in the street, conversing with a friend, suddenly lost his speech ; he recovered it after a few minutes, walked home, and made no particular complaint. In the evening of the same day, he suddenly fell from his chair, speechless, and paralytic on the right side, but without coma ; being sensible of what was said to him, and answering by signs. He was then confined to bed for several weeks without any change in the symptoms.— At the end of three months, he had recovered so far the mo- tion of his leg, as to be able tq walk a little, dragging forward the leg by a motion of the whole right side of his body. He afterwards improved considerably in bodily strength, so that he could walk for several miles ; but his thigh and leg con tinued to be dragged forward by the same kind of effort, with- out any farther improvement. He never recovered any de 208 paralysis with serous effusion. gree of motion of the arm or hand ; he could not even move the fingers ; his speech was very inarticulate, and his counte- nance was expressive of great imbecility of mind. In this state he continued without relapse, and without any farther improvement, for fifteen years, when he died at the age of 50. For a month before his death, he had been declining in strength. I saw him about four days before he died, and found him in a state resembling typhus ; his pulse frequent and weak; his tongue very foul, and dry in the middle; he made no complaint. He was not then in bed, but was con- fined to it next day, and died in three days more, of rapid sinking without coma. Inspection.—The membranes adhered firmly to each other, and to the brain, at a spot the size of a* shilling, on the upper part of the right hemisphere. There was a large quantity of fluid under the arachnoid membrane, and a considerable quan- tity in the ventricles. Near the posterior part of the longitu- dinal sinus, a small part of the sinus appeared to be thicken- ed in its coats, and the inner surface of this part was dark- coloured and slightly fungous. The cauda equina was of a remarkably dark colour, as if it had been soaked in venous blood, but without any change in its structure. No other morbid appearance could he detected, on the most careful ex- amination, in any part of the brain or spinal cord. The remarkably diseased state of the arteries of the brain, which has been already referred to, as a very common appear- ance in elderly people, may probably be the cause of tempo- rary interruptions of the circulation, and slight paralytic at- tacks, which after some time may pass off from changes which elude our observation. Perhaps something of this kind occur- red in the following case, for which I am indebted to Dr. Simson. Case CXXV.—A gentleman aged 58, in 1805, was attack- ed with hemiplegia of the right side, without coma. After the usual treatment, he improved gradually ; and at the end of five months, he had quite recovered, except that his right leg continued rather weaker than the other. In 1812, he had another attack, preceded by violent headach. From this like- wise he gradually recovered, though his recovery was much less perfect than after the former attack. He had four other attacks betwixt 1812 and 1817, which were carried off by the1 ABSORPTION OF THE COAGULUM. 209 usual remedies, bloodletting and purging. In 1817, he had another and severe attack, likewise in the right side ; his speech was unintelligible, and his mouth much drawn to the left side. He was relieved by bloodletting, &c, but from the effects of this attack he did not recover. He remained para- lytic in the right side, his mouth twisted, and his speech very indistinct. In November, 1818, he began to be affected with gangrene of the toes, which advanced slowly, and terminated fa- tally in April, 1819. From the time of his first attack, in 1805, to the second, in 1812, he always became confused and felt head- ach, when he. attempted to read or write, so that he was obliged immediately to desist; but after the attack in 1812, he was able to read and write without any confusion or unea- siness, and even without the use of spectacles, which he had formerly employed. Inspection.—The dura mater seemed considerably thicken- ed ; the pia mater also seemed thickened, and was very vas- cular. There was extensive disease in the arteries of the brain, their coats being thickened, and in many places ossi- fied. This was very remarkable in the principal trunks of the carotids and vertebrals, and was likewise traced into the smaller branches. The internal carotids seemed considerably larger than usual, and their coats were much thickened ; and the vertebrals and their brandies were affected in the same manner in a still greater degree, particularly about the tuber annulare, where the basilar artery was quite brittle, and gave off its branches in the same condition. M. Gendrin has described a case of several months stand- ing, in which nothing could be discovered but a diseased state of one of the posterior arteries of the brain, and a very slight softening of part of the cerebellum. There seems every rea- son to believe that such cases often depend upon disease of the arteries of a portion of the brain. § H.__Paralytic cases accompanied by extravasation OF BLOOD OF SMALL EXTENT. The symptoms which appear in connexion with extravasa- tion of blood in the brain, seem to depend in a great measure upon the quantity that has been extravasated. In the cases which go on to apoplexy, the blood seems in general to burst bY laceration of the cerebral substance, either to the surface, 27 210 paralysis with extravasation. or into the ventricles'. In the paralytic cases, it seems to be confined to a certain defined cavity in which the haemorrhage at first took place. This may be in any part of the substance of the hemispheres ; the corpus striatum is a very common seat of it; and it may be found in the substance of the pons Varolii, or of the medulla oblongata. It may likewise take place on the surface of the brain, as in Case CXXXI., in which the cyst which had contained it was distinctly seen in the cel- lular structure of the arachnoid. Extravasation of a certain extent, either in the substance or on the surface, seems, in ge- neral, to produce palsy of the opposite side; and as the quantity increases, the case seems to pass into apoplexy ; but it appears that extravasation may take place and produce fatal apoplexy, without having induced paralysis. Several cases have been already described in which this took place, though in all of them there was a considerable interval betwixt the attack and the occurrence of coma. When the extravasation is of more limited extent, so as to be confined to a cavity of moderate size in the substance of the brain, the patient is in general affected with palsy and loss of speech, without perfect coma ; or, if there be coma for a time immediately after the attack, it passes* off after a certain interval, and the prominent character of the disease comes to be the state of paralysis. In the farther progress of the cases of this class, we find remarkable varieties. Some of them pass, after a certain time, into fatal coma, even when the ex- travasation of blood is of no great extent; while, on the other hand, we shall find that the patient may recover entirely from the effects of extravasation of a certain extent, and may even re- cover from the immediate effects of very extensive extravasation, and survive in a paralytic state for many years. The causes of this difference seems to depend, in a great measure, upon the state of the surrounding cerebral substance. When extravasa- tion of small amount is fatal, it seems in general to be connected with ramollissement of the cerebral substance to some extent around the cavity which contains the coagulum. There is also some reason to believe, that extravasation of very small extent, in fatal cases, may sometimes be considered as the effect of the state of simple apoplexy; and that, in those instances, the fatal event is not to be ascribed to the extravasation, but to the state of simple apoplexy, which we have seen may be fatal without either extravasation or effusion. This may be considered as in some measure conjectural, but the other is more a matter of fact; namely the effect of ramollissement of absorption of the coagulum. 211 the cerebral substance surrounding the coagulum in producing a fatal disease, while we see in other cases, extravasation of greater extent entirely recovered from. The ramollissement in these cases seems to arise from a diseased state of the arte- rial system of the part, the same probably which generally gives rise to the extravasation. When the cerebral substance surrounding the extravasation continues in a healthy state, we find that coagula of very great1 size are gradually and completely absorbed. This re- markable change seems to commence at a very early period, but to advance very slowly. When we have an opportunity of seeing the coagulum, so early as fourteen or fifteen days from the attack, we find it already considerably changed in its character from the appearance of recent blood. The thinner parts have considerably disappeared, and the coagu- lum has become firmer in its texture, and of a dark brown- ish colour. In its farther progress, it assumes a firm and fibrous texture ; the dark red colour is gradually lost, and the last portion that remains is a small mass of fibrin of a slight reddish colour, which, after a certain time, also entirely dis- appears. The time required for this process must of course depend in a great measure upon the size of the coagulum, but seems likewise to be in part regulated by other circum- stances. In case CXXVIL, a coagulum, which must have been of very considerable size, had entirely disappeared in less than five months. In case CXXX., it was seen partly absorbed at the end of three months. On the other hand, Moulin found a small coagulum not quite gone at the end of a year ; and Riobe observed some of the blood still remain- ing in a cavity of small extent, after twenty months. In two cases, Serres found a hard coagulum of blood remaining, in the one at the end of two years, and in the other at the end of three years. While these changes are going on in the coagulum, the ca- vity in which it is contained becomes lined with a distinct firm membrane of a yellowish colour; and when the coagu- lum has entirely disappeared, we find the cyst remaining, and forming a distinct and well defined cavity, which is generally entirely empty. Bands of the same yellow matter which forms it are frequently seen crossing it in various directions, and producing a connexion betwixt its opposite sides at these points. The French writers believe that the cyst is at last $12 PARALYSIS WITH EXTRAVASATION. entirely obliterated; but I have never seen any thing to satisfy me that it is so. I have examined such cysts at various pe- riods of their progress, but have seen nothing like an approach to obliteration, except the bands which I have now mentioned, connecting their opposite sides, unless in case CXXXII., in which a part of the cavity did appear to be obliterated by the adhesion of its sides. The cyst appears to be distinctly or- ganized, and numerous bloodvessels have sometimes been observed ramifying upon it. It does not appear precisely at what period this remarkable membrane is deposited. Riobe describes it in one case, as existing three weeks after the at- tack ; and, in another, he thought he observed the formation of it begun in a very soft state, as early as thirteen days. M. Gendrin has given an interesting description of it in a case which was fatal in thirty-six days. The cavity was the size of a pullet's egg, and was situated between the thalamus and corpus striatum. The coagulum being carefully removed, the cavity was found to be lined by a delicate semipellucid mem- brane, which presented, when held up to the light, numerous vascular striae. The coagulum did not appear to have under- gone any change; and the opinion of M. Gendrin seems to be, that the absorption of the coagulum does not commence till this membrane is fully formed. In the cases which I have had an opportunity of observ- ing, after the disappearance of the coagulum, the cyst has in general been entirely empty. It appears, however, that it has been frequently observed by the French writers full of serous fluid. Their idea is, that serous fluid is deposited from the exhaling vessels of the membrane, and is again absorbed, after dissolving a part of the coagulum ; that in this manner the coagulum gradually disappears; and that the membrane then continues to deposit and reabsorb the serum, until the cavity is obliterated. I have already stated, that in my ob- servation, cavities even of large size are found entirely empty. Andral, however, has described several cases, in which the cysts were found containing serous fluid, many years after the symptoms had disappeared. Moulin has described a case of seventeen years standing, in which the patient had continued paralytic, with wasting of the affected limbs, and had never recovered his speech. He found a cyst containing four ounces of fluid which was tinged with blood. As the absorption of the coagulum goes on, the symptoms ABSORPTION OF THE CAOGULUM. 213 in some cases subside gradually, and entirely disappear; but in others the improvement is but partial, and we find that the coagulum had been entirely removed, while the patient con- tinued to be affected with a great degree of palsy to the end of his life. In other cases again, the symptoms appear to go off speedily, though there was every reason to believe that a coagulum was present, and could not yet be absorbed. This probably occurred in case CXXX. It appears that extrava- sated blood may be absorbed in the same manner from the ventricles, though in cases of this kind it more rarely occurs in that situation. A man, mentioned by Riobe, had an at- tack of apoplexy, which left him affected with palsy of the left side. He improved very gradually, and was entirely re- covered at the end of eighteen months, when he died of pe- ripneumony. In the right lateral ventricle, there was a small quantity of coagulated blood, and the membrane lining the ventricle was of a yellowish colour, and much thickened. In Case CXXXL, I have described an example of absorption from the surface of the brain, the cyst being formed in the cellular structure of the arachnoid, but having the same cha- racters as the cysts which are found in the substance of the brain. The following selection of cases arranged under several heads, will illustrate this modification of the disease. I shall describe the first case at some length, as it shows very re- markably the various stages of this interesting affection. A. The cyst empty—the patient dying of another disease. Case CXXVI.—A clergyman aged 29, had complained for several weeks of frequent headach, which affected him chiefly in the morning. On Tuesday, 30th November, 1819, he walked out in his usual health about 11 o'clock in the fore- noon, and about half an hour after went into a shop, when he was found to be speechless, and with his mouth twisted to one side. He was immediately taken home; he had then the use of all his limbs, and was able to walk about his room ;. he talked incoherently and inarticulately, his mouth was very much twisted to the left side, but he seemed to know his friends. Soon after, he became more incoherent and partially comatose, but resisted violently when he was bled. Pulse of 214 PARALYSIS WITH EXTRAVASATION. natural frequency. I saw him soon after the bleeding; he was then rather pale, and the pulse natural; he made eager attempts to speak, and when disturbed, sometimes became violent; but his speech 'was quite inarticulate, and he did not appear to comprehend what was said to him. After farther bleeding, purging, &c, he became more intelligent, and on the following day, 1st of December, he was much more sen- sible ; he knew those about him, and occasionally answered questions distinctly, when the answer that was necessary was very short; when he attempted more than this, he wandered into incoherence, and often appeared very anxious to describe something—but not a word could be understood. He had the use of all his limbs, and) occasionally got out of bed with great agility to obtain something which he wanted,' when he could not make the attendant comprehend what he meant. Farther bleeding and purging were employed, and there was a progressive improvement. On the 3d, he was able to speak correctly, though slowly and heavily, as if endeavouring to recollect a word which he meant to make use of. He now gave a distinct account of his seizure on the 30th ; he said " he felt a violent headach attack him suddenly while he was pulling on his boots immediately before going out, and that it continued after he went out; he remembered going into the shop of a person whom he named, and the person telling him that he was very ill and must be taken home." From this time he improved progressively, and by the 18th was in his usual health, except some slight remains of thickness of speech, and a slight degree of confusion for a few minutes after first awaking in the morning. These symptoms soon disappeared, and he enjoyed very good health till about 15th November, 1820, when he was suddenly seized in the after- noon with loss of speech and palsy of the right arm. I saw him in an hour after the attack ; little or no blood could be obtained from a vein, but the temporal artery being opened very low down, bled freely to 20 ounces, when he became faint. He then took purgatives ; next day he was much bet- ter, and in a few days the symptoms were entirely removed. He now continued well for about a month. On the 16th December, 1820, he went into the country on horseback; o about three miles from town he was observed by a person who passed him, running by the side of his horse nearly speechless, and with the appearance of a person intoxicated. In this state he went to the house of a person with whom he ABSORPTION OF THE COAGULUM. 215 was acquainted, but could not make himself understood, and soon after his arrival became completely comatose. The usual remedies were employed without any immediate effect. During the remainder of the 16th, and through the whole of the 17th, he continued in a state of perfect coma, notwith- standing repeated bleeding to faintness, and the other usual remedies. On the 18th, about five o'clock in the morning, he came out of the coma, and from this time recovered gra- dually. On the 21st, he was able to be out of bed and to walk steadily, and was soon after restored to his usual health, except that his speech continued considerably indistinct. Af- ter some time, he began to complain of headach, notwith- standing very abstemious diet; this was relieved by bleeding, and for a considerable time it was necessary to repeat small bleedings once in two or three weeks. In this manner he enjoyed tolerable health, but never entirely recovered from the effects of the last attack; his speech continued thick and somewhat indistinct; his mind was evidently weakened ; his countenance was vacant, and his temper was irritable. But he engaged in all the ordinary transactions of life, and in the lighter duties of his profession, such as baptism and marriage ; he never preached, though he was very anxious to attempt it; he had the use of all his limbs, and was able to take a great deal of exercise. He continued liable to headach, for which he was bled occasionally, and once had an attack of haemop- tysis, which went off in a few days. He continued in this state till the 20th May, 1822, when he began to be affected with cough, dyspnoea, and frequent pulse; and of this affec- tion in the chest he died, on the 7th of June, without any re- currence of the symptoms in the head. Inspection—In the substance of the left hemisphere of the brain, about the centre, and about equally distant from the ventricle and the surface, there was a cyst an inch and a half long, and one inch deep. It was quite empty, but was lined by a yellowish firm membrane of considerable thickness. This membrane could be easily separated from the surrounding ce- rebral substance, to which it adhered very slightly. In the substance of the right hemisphere, in a situation exactly corres- ponding to the former, there was another cyst of a similar character but smaller. It was a narrow sinus, and of a diame- ter which could have admitted a quill: it was like the other quite empty, but lined by the same kind of yellow membrane ; there was a small quantity of clear fluid in the ventricle; there 216 PARALYSIS WITH EXTRAVASATION. was no other morbid appearance. In the lungs, there was slight hepatisation and extensive disease of the bronchial membrane. Case CXXVII.—A gentleman aged 56, in one of the last days of June, 1826, while walking through the museum of the University of Edinburgh, was suddenly seized with loss of speech. He walked with difficulty and some assistance to the house of a friend in the neighbourhood, where it was first observed that he had lost the use of his right side. After a short time he became nearly comatose, and continued so for some days. After repeated bleeding, purging, &c, he be- came gradually more sensible; but it was now found that he had lost almost entirely the memory of words, though he ap- peared to comprehend what was said to him. He gradually recovered the use of his leg, so as to be able to walk a little. But his arm made very little improvement, and both his speech and his memory of words continued very imperfect; his recollec- tion of persons and events seemed to be tolerably good. He was improving very gradually in all respects, till about the end of October, when he began to be affected with a disease of the chest, of which he died in the end of November. The paralytic symptoms continued in a very considerable degree to the last, especially in the right arm, and in his speech, which continued very indistinct. I saw him a short time before his death, along with Dr. Alison, to whom I am indebted for the history of the previous attack. Inspection.—In the substance of the left hemisphere, on the outer side of the ventricle, we found a cyst about an inch and a half long and one inch deep ; it was quite empty, and lined by a yellowish membrane similar to that which has been de- scribed in the former case. Case CXXVIII.—A lady aged about 50, was attacked with hemiplegia in April, 1817, and, after stupor of several days continuance, came out of it gradually with palsy of the right side, and very indistinct speech. It was several months after the attack when I first saw her. She was then in pretty good general health, but with very little improvement of the limbs. She could drag the leg forward a very little, the arm she could not move at all, and the fingers of the affected hand were bent inwards, and could not be made straight but by some force. Her farther improvement was very slow. In ABSORPTION OF THE COAGULUM. 127 the course of 1818, she acquired more use of her leg, being able to support herself with a stick, and to walk a few steps: her speech also became more distinct, but the arm continued completely paralytic. She had made no farther improvement, when, in August 1819, she began to complain of breathless- ness, and died rather suddenly in a fit of dyspnoea. Inspection.—The ventricles of the brain contained several ounces of fluid, and it appeared quite evident to all who were present at the examination, that the left ventricle was much larger than the right. On the outer side of the left ventricle, and separated from it by sound cerebral substance of about a quarter of an inch in thickness, there was a cyst similar to those described in the former cases ; it extended longitudi- nally nearly three inches, and was as much or more in depth ; it terminated below in an angle, corresponding with the nar- row edge of the middle lobe of the brain, which lies in the an- gle of the sphenoid bone, behind the clinoid process; the ca- vity extended here to within a quarter of an inch of the base of the brain. This remarkable cavity was entirely empty; it was lined by a fine yellow membrane, and bands of the same substance with the membrane intersected it in several places, connecting the opposite surfaces, which in other places, though in contact, were quite unconnected. This membrane existed throughout the whole cavity, and was quite obvious even in the sharp angular termination already mentioned. The brain was in other respects healthy. There was considerable effu- sion in the pleura, and extensive accumulation of puriform mucus in the bronchial canals. B. The cyst empty—the patient dying of a fresh attack. Case CXXIX.—A lady aged 40, on the 10th of April, 1821, complained in the morning of violent headach, and had some vomiting; soon after she was seized with perfect palsy of the right side, with very inarticulate speech, and a considerable degree of coma. She was relieved by the usual treatment; the symptoms subsided gradually, and in eight or ten days she was quite well. She occasionally felt a slight degree of weakness of the side which had been affected, but she mere- ly expressed it by saying that it was different from the other, and she continued to enjoy good health until August, 1822, when she had another attack in which the right side was again 28 218 PARALYSIS WITH EXTRAVASATION. affected. She soon recovered from the immediate effects of this attack, but the leg and arm continued long very weak, and her speech was indistinct, with considerable confusion of thought, and, during the following winter, she was able for very little exertion. In the summer of 1823, she improved considerably, so that shecould walk a good deal, leaning upon the arm of another person ; her speech was more distinct, and her mind very considerably improved. It was, however, ob- vious that the effects of the attack were not entirely removed, as she still dragged her leg a little in walking, and had less command of the right hand than of the left. She was going on in this manner, and in other respects enjoying pretty good health, when, in December, 1824, she was suddenly seized, while sitting at breakfast, with palsy of the left side, and twisting of the mouth; and soon after became comatose, with total loss of the power of swallowing. She died in four days. Inspection.—In the right hemisphere of the brain, towards the anterior part, there was a coagulum of blood the size of a pigeon's egg; it lay on the outside of the ventricle, and close- ly bordering upon it, but without any communication. In the corresponding situation in the left hemisphere, there was a cyst, running obliquely backwards on the outside of the ven- tricle, and quite distinct from it. It was about an inch and a half long, and nearly an inch in depth; it was quite empty, and lined by a soft yellowish membrane. This lady was like- wise affected with extensive disease of the ovarium, on ac- count of which I had seen her at different times, both before and in the intervals of the paralytic attacks along with Dr. Beilby. C. Two cysts empty—the coagulum partly absorbed from a third—the patient dying of a fresh attack. Case CXXX.—A man aged 56, in the end of November, 1822, had an attack of hemiplegia of the right side, with loss of speech, from which he recovered after the usual treatment; and at the end of a fortnight was in his usual health, except that he felt a degree of stiffness of the affected limbs. He, however, made no complaint, but returned to his usual em- ployment, as keeper of a tap-room, and to his usual mode of living, which was eating and drinking without restraint. He ABSORPTION OF THE COAGULUM. 219 continued to go on in this manner till the end of February, 1823, when he was found one afternoon, in his cellar, lying in a state of perfect apoplexy. He died in thirty-six hours. Inspection.—In the left ventricle of the brain there was bloody serum, with some coagulated blood, which appeared to have burst from a cavity in the substance of the hemisphere on the outer side of the ventricle. This cavity contained a coagulum of the size of a pigeon's egg, and communicated with the ventricle by a small ragged opening. The surround- ing cerebral substance was in some places considerably soft- ened. Behind this cavity, but separated from it by sound cerebral substance, there was a smaller cavity, which was seated in the posterior part of the left thalamus. It contained a small quantity of grumous blood, of a very dark colour, but not sufficient to fill it, a great part of the cavity being in a collapsed state. Exactly opposite to this cavity, in the posterior part of the right thalamus, there was another ca- vity capable of containing a small bean. It was quite empty, but lined by a firm soft membrane, of a yellow co- lour. In prosecuting farther the dissection of the brain, a fourth cavity was met with in the substance of the medulla oblongata, or rather under the pons Varolii; it was capable of containing a very small bean, but empty like the other, and lined by a similar membrane. On inquiring farther into the history of this man, I afterwards found that he had had two attacks previously to the first of those above described; the one eighteen months before his death, and the other at a former period. Both were said to have been very slight, and to have produced only numbness of his arm for a few hours; I could not obtain a more particular account. D. The cyst on the surface. Case CXXXL—A gentleman aged 74, in April, 1823, had an apoplectic attack which seized him suddenly in the evening. He fell down deprived of sense and motion, and on partially recovering, was found to be without palsy, except in his speech, which was quite unintelligible. He had then con- siderable stupor,*bordering upon coma, and at times showed great restlessness and impatience in his ineffectual attempts to make himself understood. After large and repeated bleeding, and the other usual remedies, he gradually improved, so that 220 PARALYSIS WITH EXTRAVASATION. after six or seven weeks he was able to walk out, and was in good general health, but with very inarticulate speech, and considerable confusion of mind. In conversation he was evi- dently aware of what he meant to say, but could not make it intelligible to others ; he put one word for another, or the name of one article for another, often in a ludicrous manner; he could not name persons, though he evidently recognised them; and, on one occasion, while he was walking in the street with a friend, being very anxious to say something to him in regard to another gentleman whom he could not name, he hurried his friend along to the door of the gentleman's house and pointed to the name plate. In this manner he passed the summer, and the following winter, and great part of the fol- lowing summer, being in good bodily health, but restless and unhappy in his mind, and with the same confusion of thought and inarticulate speech. He was incapable of reading a word, or of expressing himself intelligibly on any subject, except to those who were constantly with him, who got into the way of understanding him on ordinary topics. In the end of sum- mer, 1824, he began to have complaints in his chest, of which he died on the 19th of December. On the day on which he died, he was more distinct in his mind than he had been at any time since the attack. Inspection.—There was an unusual quantity of fluid under the arachnoid, so that at least eight ounces were collected; and when it was all discharged the brain seemed remarkably collapsed. The arachnoid and the pia mater were considera- bly thickened. The only other morbid appearance was a de- position of a firm yellowish matter, on the outer side of the left hemisphere ; it extended about three inches from before back- wards, and in depth corresponded to about the lower half of the hemisphere. This substance when closely examined, was found to be a collapsed cyst; and it appeared to be formed betwixt the arachnoid and the dura mater, or partly involved in the arachnoid. It exactly resembled the substance which is found lining the cysts in the substance of the brain; and there seemed to be little doubt, that it had been the seat of an extravasation which had been absorbed. There was ex- tensive ossification of the arteries of the brain ; the substance of the brain was healthy. There was considerable effusion in the thorax, with enlargement of the heart, and disease of the valves. ABSORPTION OF THE COAGULUM. 22l Attempts have been made in cases of this class to establish a connexion between the seat of the disease and the particu- lar organs which are affected ; but these attempts do not seem to have been attended with much success. Serres has con- cluded that the arm is chiefly affected, when the extravasation is in the posterior part of the hemisphere, and the leg when it is in the anterior part, or in the corpus striatum. Boml- hrud has been at pains to prove that the speech is affected when the disease is in the anterior part of the brain. But this has been disputed in a memoir by Cruveilhier, where he de- scribes several cases in which loss of speech was a prominent symptom, while the disease was not in the anterior part of the brain, but in some other part, as the middle lobes, and even the cerebellum. In one of his cases, a man was seized, in a fit of passion, with palsy of the left side and impaired speech. He recovered after some months, but his speech continued a little embarrassed. After eight years, he was attacked with palsy of the right side, and difficulty of swallowing, and died in ten days. In the middle lobe of the left hemisphere, there was a coagulum of blood the size of a nut, surrounded by some ramollissement. In the left lobe of the cerebellum there was a cyst half an inch in diameter, lined by an organized membrane, and containing a small quantity of limpid serum. Another of his cases is sufficiently remarkable : A man aged 48, was first attacked with loss of speech and twisting of the mouth, which continued. After six months, he was seized with palsy of the right side. He recovered from this, but his speech continued much impaired. After two years more, he had a succession of attacks in which the right leg was first affected, and afterwards the left leg; the embarrassment of his speech was increased in each attack. Finally, at the end of another year, he had a fatal attack, with loss of speech, loss of the power of swallowing, and some vomiting. In the left hemisphere, there were three cysts near the surface. In the right hemisphere, there were two cysts in the corpus striatum, and two in the thalamus. In the substance of the tuber annulare, there was a, cavity containing recent blood not coagulated.— In one of Dr. Cheyne's cases, there were three distinct extra- vasations ; one in the substance of each corpus striatum, and one in the third and fourth ventricles. The symptoms were apoplectic with some convulsion, and after some time para- plegia. In another, the extravasation was in the substance of the pons Varolii, from which it had forced its way into the 222 PARALYSIS WITH EXTRAVASATION. fourth ventricle. The symptoms were severe headach, follow- ed by perfect apoplexy without paralysis. In a case which occurred to a friend of mine, there was a round coagulum, the size of a musket bullet, in the iter ad quartum ventriculum.— The attack consisted of paralysis of the left arm, in a few mi- nutes followed by apoplexy, which was fatal in a few hours. In a singular case described by Mr. Howship, the extravasa- tion wa*s distributed in the substance of the medulla oblon- gata, in such a manner as to form several thin strata, alter- nating with strata of the cerebral matter. The case was a sudden attack of perfect apoplexy, which was fatal in two days. A remarkable case of the same kind is mentioned by Dr. Duncan in his Clinical Reports. Paraplegia is an uncom- mon occurrence in cases of this class, insomuch that it has been doubted whether it ever arises from an affection of the brain.* Serres has described a case of paraplegia, with palsy of the left arm, connected with extravasation of blood under the right hemisphere of the cerebellum. It occurred also in a case just quoted from Dr. Cheyne, in connexion with extra- vasation in the third and fourth ventricles. Another is men- tioned by Boerhaave, in which it preceded apoplexy,! and was connected with extravasated blood under the cerebellum, and about the top of the spine. It does not appear, however, that in any of these cases there was an examination of the spinal canal, so that perhaps we are not entitled to found any conclusion upon them; the subject deserves careful exami- nation. I conclude this part of the subject with the following case, showing a remarkable feature in this form of the disease, namely, loss of the cerebral substance to a very considera- ble extent, at the place where the extravasation had been si- tuated. Case CXXXII.—A gentleman aged 64, was first seized with an attack of apoplexy in 1824, from which he recovered under the usual treatment, but retained some imperfection of speech, and a degree of weakness of the left .side. Some months after, he had a second attack, and in July, 1825, a third, accompanied by convulsion, in which he lay in a state of insensibility for 36 hours, and was not able to leave his * See an able and ingenious paper by my friend Dr. Burder, in the Medical and Physical Journal, for June, 1827. PARALYSIS WITH RAMOLLISSEMENT. 223 room for a fortnight. From this time to the period of his death in 1830, he had a succession of apoplectic attacks, amounting in all to twelve. After these attacks, he was ge- nerally able to leave his room in a few days, but each left him more and more embarrassed in his speech, and paralytic on the left side, with distortion of the mouth, and he died in the 12th attack in 1830, after an illness of eight or ten days ; during which, he lay in a state of nearly perfect coma, with total loss of speech and perfect palsy of the left side. Inspection.—On removing the dura mater, a remarkable de- pression was found on the surface of the right hemisphere, forming a deep and well-defined cavity, capable of containing from three to four ounces of fluid. It had been filled by a clear serous fluid, which escaped when the dura mater was wound- ed in opening the head. The surface of the cavity presented nothing different from the ordinary appearance of the cerebral surface, being covered by the pia mater and arachnoid ; but the dura mater had been separated by the fluid which had fill- ed the cavity. On cutting into the cerebral substance which formed the cavity, it was found more dense than natural, and a cavity was exposed in the substance of the hemisphere im- mediately beneath it, presenting the usual appearance of the collapsed cyst which had been the seat of extravasation. It was about an inch and a half in length,—lined by a yellow membrane of the usual appearance, and part of it was oblite- rated by the adhesion of its opposite surfaces. Several other very small cysts were observed in various parts of the hemis- phere, but they were all empty, and no appearance could be discovered capable of accounting for the fatal attack. § III.—Of the cases accompanied by ramollis- sement. In an early part of this work, I have submitted a conjecture that the ramollissement of the cerebral substance is analogous to gangrene in other parts of the body ; and that, like gan- grene, it may arise from two very different causes. These are inflammatory action, and failure of circulation depending upon disease of the arterial system. Ramollissement arising from the former cause I conceive to be an affection which holds a pro- minent place in the pathology of acute affections of the brain, occurring in early life, and being accompanied by symptoms 224 PARALYSIS WITH RAMOLLISSEMENT. of an acute character. I have given my reason for consider- ing this as an affection in many respects distinct from the ra- mollissement, investigated with such care by the French pa- thologists, and particularly M. Rostan. This appears to be a disease of the aged,—the cases described by M. Rostan, hav- ing chiefly occurred in persons from 70 to 80, and upwards. It is accompanied by symptoms of a paralytic and comatose character, and is frequently complicated with extravasation of blood. I have already alluded to the frequency and the extent of the disease of the arterial system of the brain in advanced life ; and there appears to be considerable probability in the conjecture, that this may be the source of the ramollisement in the cases of this class. The disease of the arteries consists of ossification, with thickening and contraction, frequently to a great extent, and sometimes with separation of the inner coat. It corresponds precisely with the state of the arteries, which we know to produce gangrene in other parts of the body, particularly in the toes and feet of old people; and, in another place, I have described a remarkable case, in which separation of the inner coat of the iliac artery produced gan- grene of the whole extremity, which was fatal in four days.* The symptoms accompanying the ramollissement, in this form, do not appear to differ remarkably from those which oc- cur in the other cases of palsy. The attack is frequently pre- ceded by some of the usual symptoms indicating a tendency to disease of the brain ; such as, headach, giddiness, partial loss of recollection, and numbness or prickling of some of the limbs. After some time, there occurs suddenly or more gra- dually a loss of power of one or more limbs, with embarrass- ment of speech, but without loss of intelligence. The patient is then confined to bed, helpless and oppressed, with more or less of palsy, but with a certain degree of intelligence ; and dies after various intervals, either with gradual sinking, or with coma for a few days before death, or sometimes with symptoms of low fever. The symptoms seem frequently to advance more slowly than in the cases from extravasation,— one organ, as the tongue, being first affected, and then one or more limbs after some interval. Pain in the affected limb is also a frequent occurrence ; and rigid contraction of them has been much insisted on, as a symptom characteristic of the ra- mollissement. It is, however, by no means a uniform symp- * Edin. Med. Journal, vol. xvUj>. 308. PARALYSIS WITH RAMOLLISSEMENT. 225 torn, for it is frequently wanting altogether ; when it is pre- sent in the early period of the disease, it frequently disap- pears in the course of it; and in some of Rostan's cases, it left the limbs of the paralytic side and affected those of the other. It is also frequently observed in cases entirely of an- other kind—as in certain states of fever which terminate fa- vourably. Convulsive affections of the limbs are also occa- sionally met with. The patient is frequently, in the early stages, quite intelli- gent, and observant of every thing, although unable to speak, or able to speak but imperfectly. As the disease advances, he frequently becomes more oppressed and somnolent; but he is intelligent when roused, not entirely comatose till the last period, and sometimes never entirely so. In other cases, there is at first a considerable degree of coma, which after the first day goes off, the patient becoming quite intelligent, and giving appearances of recovery, which are found to be falla- cious. The sensibility of the affected limbs is in some cases impaired, in others little affected ; and, in some cases, they are found acutely painful. The ramollissement is of various extent. It seems to be most commonly seated in the more external parts of the brain, near the surface, but sometimes is found in more deep-seated parts, particularly in the corpus striatum. A small coagulum of blood is sometimes found in- volved in the softened part; and sometimes the softening is found to have taken place around the cyst of an old extrava- sation. I have not seen much of this form of the ramollissement, in its uncombined state; but it seems to be of very frequent occurrence in the French hospitals. The two -following cases are the best examples of it I find among my notes. The se- cond of them perhaps may be considered as having some af- finity to the cases of the inflammatory character; and, indeed, some of M. Rostan's own cases afford traces of inflammation. Case CXXXIIL—A man aged 58, of a full habit and florid complexion, on the 7th of March, 1817, about nine o'clock in the morning, without any previous complaint, was found to* have lost his speech. I saw him about half-past ten, and found him walking about his room; he had the full use of all his limbs; understood what was said to him, and answered by signs; he could put out his tongue freely, but could not articulate a word. He did not admit that he felt any uneasi- 29 226 PARALYSIS WITH RAMOLLISSEMENT. ness in his head, his pulse was natural and of good strength, and his face flushed. The usual remedies were employed through the day, without producing any change in the symp- toms. In the morning of the 8th, he was found to be affect- ed with perfect hemiplegia of the right side ; and the tongue, when put out, was turned to the right side ; he was still quite intelligent, but made no attempt at speech. He now lay for a month without any change in the symp- toms ; he slept well in the night; in the day he was quite in- telligent, and answered by signs, but continued entirely speech- less. For some time his tongue, when put out, was turned to the right side, but afterwards ft became strait. He took his food, and appeared to suffer no pain; the pulse was natu- ral ; the right side continued completely paralytic. About the 10th of May, he began to have violent pain in the paraly- tic limbs, and could not bear to have them moved in the most gentle manner without screaming; nothing was to be seen about the limbs that accounted for the uneasiness. For about a fortnight he now suffered constant pain; his strength sunk, and he lost his appetite. He then had some vomiting, but not urgent; his pulse became feeble, and his features collaps- ed ; and he died in the end of May, of gradual sinking, with- out coma. There had been no recovery of speech, or of the motion of the right side. Inspection.—On opening the head, there appeared a remark- able depression on the upper part of the left hemisphere of the brain, about two inches in length and somewhat less in breadth, the dura mater sinking into it to the depth of about half an inch. On removing the dura mater, the substance of the brain at this place was to a great extent broken down, soft and pul- py ; and this appearance extended along nearly the whole up- per part of the left hemisphere. Tracing this mass backwards, it was found to be terminated by a coagulum of blood, not larger than a small bean. The coagulum was soft like recent blood, and was situated about two inches from the posterior surface of the hemisphere, nearly on a level with the horizon- tal part of the lateral ventricle. There was no effusion in the ventricle. Case CXXXIV.—A man aged 60, of rather a slender and feeble habit, had complained for nearly two months, of fre- quent pain in the right side of the head, and an occasional feeling of numbness in the left arm. In the end of Septem- PARALYSIS FROM INFLAMMATION. 227 ber, 1818, this pain rather increased; he had twisting of his mouth, dimness of vision of the left eye, and slight numbness of the left hand. After bleeding and the other usual remedies, he was much relieved, and returned to his usual employment. About a week after this, he was suddenly seized with palsy of the left side, and inarticulate speech ; his mind was distinct; he seemed to have some headach, but not severe ; his mouth was drawn to the left side. The usual remedies were employ- ed without relief. He continued in the most helpless state of paralysis, being unable to turn from off his back, but quite distinct, and able to express all his feelings : pulse natural. In this state he lived a month without any change of the symp- toms, except that about a week before his death he was able to move the paralytic leg a little ; this slight degree of motion continued three or four days, and then ceased. Two days before his death he was suddenly seized with perfect loss of speech; and this was followed in a few hours by coma, from which he did not recover. Inspection.—The pia mater on the upper part of both he- mispheres appeared thickened, and was remarkably vascular. Both lateral ventricles were distended with fluid. The sub- stance of the brain was healthy, except on the outer part of the right hemisphere, where there was a considerable portion in a state of complete ramollissement. There was considera- ble effusion under the arachnoid membrane. § IV.—Paralysis from inflammation, and its conse- quences. This part of the subject it is only necessary to refer to very briefly in this place, in connexion with the general arrange- ment of the sources of paralysis. It has been already consi- dered at some length in a former part of this essay, particularly in connexion with inflammation of the cerebral substance. We have there seen paralysis, which had come on with the same rapidity as in the cases considered under the present sec- tion, connected with simple inflammation of the substance of the brain,—with this inflammation passing into ramollisse- ment,—and with the encysted abscess. We have likewise seen it coming on in a more gradual manner, in connexion with a very low inflammatory action in the cerebral substance, which seems to terminate by induration of the affected part. 228 GENERAL PATHOLOGY OF PARALYSIS. I shall in this place only add the following example of this modification of the disease. Case CXXXV.—A gentleman aged about 60, whom I saw along with Mr. William Brown, had been for four years af- fected with paralysis of the right side, and indistinctness of speech. Without any increase of these symptoms he died gradually exhausted by dyspnoea and general dropsy, connect- ed with disease of the heart. Inspection.—In the anterior part of the left hemisphere, we found a portion of the cerebral substance the size of a large walnut, very much changed in its appearance, being of a brownish-yellow colour; this portion was likewise much firmer than the healthy cerebral substance, except at its lower part, where it was soft and approaching to suppuration. It is chiefly when the patient dies of some other disease, that we find this affection in the state of simple induration; when it becomes itself the fatal disease, it is generally by passing on to partial suppuration or ramollissement. Exam- ples of this kind have been formerly referred to. In regard to the paralytic state in general, there are several important circumstances which may be referred to very briefly. In some cases of palsy there is loss of motion without loss of feeling; in others, the feeling is lost also. But some singular cases are on record in which loss of feeling took place with- out loss of motion. Several examples of this are described in the Memoirs of the Royal Academy of Sciences. The most remarkable is the case of a soldier, a very strong man, and able for all his duties, who had so completely lost the feeling of his right arm and leg, that he allowed the parts to be cut, or red hot irons applied to them, without complaining of any pain. A gentleman, mentioned in the same paper, had a simi- lar peculiarity in his right arm.* Some interesting examples of the same kind are described by Mr. Broughton in the Me- dical and Physical Journal for 1827. In a case which is re- lated in the Ephemer. Naturae Curios., there was loss of mo- tion on the one side, and loss of feeling without any diminu- tion of motion on the other.f A gentleman who was under the care of Dr. Hay of Edinburgh, had two paralytic attacks at * Mem. de 1'Acad. Royale des Sciences, anno 1748. t Eph. Naturae Curios. Cent. II. Obs. 196. GENERAL PATHOLOGY OF PARALYSIS. 229 the distance of eight months from each other. In the first there was perfect loss of feeling, with only partial loss of mo- tion ; in the second there was perfect loss of motion, with on- ly, partial loss of feeling. He recovered perfectly from the first attack after a short time; but, after the second, though he recovered partially, he continued to drag his leg, and after a year or more died of apoplexy. It is unnecessary to refer the scientific reader to the light which has been thrown on this curious subject by the discoveries of Sir Charles Bell. In cases in which there has been loss both of feeling and motion, we frequently observe recovery of feeling, without re- covery of motion. Berdotus, on the other hand, describes a case in which there was recovery of motion without recovery of feeling ;* a similar case is related by Burserius.f Increas- ed acuteness of feeling in paralytic limbs has also been observ- ed ; and I have referred to a case, in which, connected with disease in the brain, there was such an increased sensibility of the arm, that the least breath of cold air excited convulsion. Dr. Falconer, in the Mem. of the Med. Society of London, vol. ii., mentions a gentleman, who, after a paralytic attack, had such a morbid state of sensation, that cold bodies felt to him as if they were intensely hot. When he first put on his shoes, he felt them very hot, and as they gradually acquired the temperature of his feet, they appeared to him to cool. Paralytic limbs sometimes become intensely painful without any obvious cause; examples of this have been given, and a case has also been referred to, in which recovery from palsy was accompanied by such pain, that the limb remained use- less. When paralytic limbs are recovering, the recovery sometimes begins at the extreme parts of the limb, as the fin- gers and toes, and extends gradually upwards ; and sometimes it begins in the part next the body, and extends gradually to the extreme parts. The same variety occurs in the first at- tack of paralysis, when it takes place so slowly as to enable us to observe its progress. It seems in general to begin in the more extreme parts, but I have seen one patient who could write distinctly with his arm supported upon a table after the arm from the shoulder to the elbow was completely paralytic ; in a few hours after the hand was paralytic also. M. Velpeau has described the case of a soldier in the hospital of Tours, * Act. Helvet. torn. vi. p. 191. f Iustitut. Medicin. Pract. vol. iii. p. 76. 230 GENERAL PATHOLOGY OF PARALYSIS. who had complete palsy of the right arm from the shoulder to the middle of the fore-arm, while the hand was not in the least affected. He recovered in three months.* In regard to the temperature of paralytic limbs, I think it is generally supposed, that they are colder than the healthy limbs; but this does not appear to be the case. The truth seems to be, that they have lost in some degree that remarkable power, possessed by the living body in the healthy state, of preserving a medium temperature; and that, according to the tempera- ture to which they have been exposed, paralytic parts become hotter or colder than sound parts, which have been exposed to the same temperature.^ A case has been related to me by a friend, in which a medical man paying a visit to a paralytic patient, found the paralytic arm so intensely hot that it was painful to touch it. This, upon inquiry, was found to be owing to the application of very hot bran, which the patient had made to the arm by the advice of a neighbour, though he was himself insensible of the change of temperature. Some interesting phenomena are presented by the conditions of the mental faculties, connected with the paralytic affections, or which remain after recovery from the apoplectic. One of the most common is a loss of the memory of words, and this has sometimes been observed to be confined to words of a particu- lar class, as nouns, verbs, or adjectives. The patient is fre- quently observed to have a distinct idea of things and their relations, as well as of persons, while he is entirely unable to give them names, or to understand them when they are named to him. A singular modification of this condition has been related to me. The gentleman to whom it referred could not be made to understand the name of an object when it was spoken to him, but if the name was written he comprehended it immediately. Another frequent modification of the affection consists in putting one word, or one name of an object in the place of another; and a very singular circumstance in some cases of this kind is, that the patient always applies the names in the same manner, so that those who are constantly with him come to understand exactly what he means. In one case of this kind, a gentleman, who was in other respects pretty well recovered, when he wanted coals put upon his fire, al- ways called for paper, and when he wanted paper, he called for coals, and these names he always used in the same sense. * Archives Generales, January, 1825. GENERAL P rHOLOGY OF PARALYSIS. 231 In other cases the patiei seems to invent names, being words which to a stranger are quite unintelligible, but he always uses them in the same sense, and his regular attendants come to know what he means by them. In the general pathology of paralysis there is much obscuri- ty. We find it connected with a great variety of morbid con- ditions of the brain, and on the other hand we find all these existing without producing it. We cannot attempt to explain these difficulties, and must content ourselves with a simple view of the facts as they stand in the present state of our knowledge. We have found paralysis connected with the following variety of morbid appearances. I. Simple and recent inflammation of the cerebral sub- stance. II. This inflammation passing into ramollissement. III. The encysted abscess of the brain. IV. Induration of a portion of the cerebral substance. V. Extravasated blood in the ventricles; on the surface of the brain ; and in cavities or cysts in the substance of the brain. VI. The empty cysts from which extravasation has been absorbed. VII. Serous effusion on the surface of the brain. VIII. Extensive disease of the arteries of the brain. To this enumeration we have also to add the following points which have not arisen so directly out of the preceding observations. IX. Morbid changes in small portions of the cerebral sub- stance. Several years ago, I attended a gentleman who was affected with very slight palsy of the right side, which con- tinued for eight or ten months without becoming either better or worse; he was pale and of a very spare habit, and had made very little complaint of his head. He at last died co- matose, after a few days illness. The only morbid appear- ance was a portion of the left hemisphere, at the very lower part of the middle lobe, which was altered in its texture so as to have very much the appearance of fungus haematodes. The part so diseased was about the size of a large walnut. Several cases are described by Andral under the name of can- cer of the brain, in which small portions were found in a state of disease resembling this. The symptoms in general were 232 GENERAL PATHOLOGY OF PARALYSIS. long-continued pain, referred to one part of the head, with paralytic symptoms. X. Loss of a considerable portion of the cerebral substance. One of the most remarkable examples of this on record is a man mentioned by Mr. O'Halloran, who, after an injury of the head, lost a great part of the frontal bone on the right side. The bone had been completely broken to pieces ; some of the pieces were extracted immediately after the injury, and others were discharged after a day or two. A great opening was thus formed, and extensive suppuration having taken place, there were discharged through it at each dressing im- mense quantities of purulent matter, mixed with large pieces of the cerebral substance, making, after some time, " a fright- ful cavern" in the very substance of the brain. On the 8th day of this affection the left hand and arm became paralytic, and the left thigh and leg on the 10th day. The man lived to the 17th, retaining his faculties to the last, and having been through the whole course of the disease perfectly composed and intelligent, and his pulse quite natural. No account is given of the dissection, or of the actual loss of the cerebral matter; but the report shows that it must have been very great. "On the 8th day," Mr. O'Halloran remarks,—" the sore continued to discharge greatly, insomuch, that when I affirm that not less than three ounces of the brain, with a hor- rid smell, followed every dressing, I am certain that I am a good deal under the quantity;"—and, again, on the 13th day,—"the cavern was terrible, and I feared that the remains of the lobes of the right side of the brain would follow."—In the conclusion of this remarkable case, it is added, that the man "preserved his intellect to the very moment of dissolu- tion."* XI. Cold. A man mentioned by Dr. Clerk, became para- lytic in both legs, and partially in the arms, in consequence of being much benumbed with cold in travelling on the top of a coach; he derived benefit from mercury and warm bath, and was nearly recovered in eight or ten months.f I have seen a case of paraplegia which was referred to this cause, and which, when I saw it last, had continued for about four years with very little improvement. . Dr. Powel has described three cases of paralysis of one side of the face, producing great * O'Halloran on Injuries of the Head, p. 103. t Edinburgh Medical Journal; vol. iv. p. 266- GENERAL PATHOLOGY OF PARALYSIS. 233 twisting of the mouth, and in one of them, inability to shut the eyelids. The affection came on immediately after expo- sure to cold, by a cold wind blowing upon one side of the face; it was not accompanied by any other symptom ; two of them were well in eight or ten days; but a third, a child, was not free from the complaint for three months. They seemed to derive benefit from sudorifics and the application of steam. This was probably an affection of the portio dura.* XII. Local affections of nerves. For the facts connected with this curious subject, I refer to the beautiful investigations of Sir Charles Bell. One of the most common examples is paralysis of one side of the face from an affection of the portio dura. I have seen several examples of it; in some of them it has been a transient affection, and apparently connected with some inflammatory action about the external ear or the parotid gland ; and it has yielded readily to topical bleeding and blistering. In other cases it is connected with disease of the bone, and proves most untractable. The temporary para- lysis which arises from accidental pressure upon a nerve is fa- miliar to every one; but singular cases occasionally occur in which the effects are more permanent. An instance of this kind has been related to me in which the paralysis did not go off for several months, and another in which it was permanent. In the latter case, it took place in the fore-arms and hands of both sides, and was induced by pressure in consequence of leaning for a long time upon a bar of wood while the person was stooping forward in his anxiety to witness some public exhibition. Mr. Brodie has described a case of paralysis of one side of the face which followed a blow on the cheek, and recovered in three months. XIII. There is a modification of paralysis which seems to be connected with the state of the circulation in the affected part. A lady, mentioned by Dr. Storer,t was recovering from a pneumonic attack, when one morning, after a restless night, she was suddenly seized with an acute pain in the left shoul- der, extending to the arm, and at the same time the whole left side became paralytic. The leg retained an obscure de- gree of motion and feeling, but the hand and foot were insen- sible to the prick of a needle. The parts were cold, and all the arteries in them were without pulsation. On the right side * Transactions of the College of Physicians, London; vol. v. t Trans, of a Society for the Improvement of Medical and Surgical Knowledge, vol', iii. 30 234 GENERAL PATHOLOGY OF PARALYSIS. of the body, the pulse was of good strength, and a little fre- quent. After a few hours the pain shifted to the leg and foot; and she had also some obscure pain in the forehead, which was removed by bleeding with leeches. The pain of the leg and foot abated after twelve hours, and she had then no com- plaint except the paralysis. For several days she seemed to be improving a little in the motion of the parts, but they con- tinued cold and without pulse; on the fifth day, she had an uneasy feeling in the epigastrium, with sense of suffocation; her breathing became short and hurried, and she died in the night; the body was not examined. A gentleman, mentioned in the same paper, was seized with paralysis of the right arm as he sat at breakfast, having been previously in perfect health. He did not complain of any pain, but the arm was pale, and every part of it without pulse; in the left arm the pulse was natural. After four hours he became faint, with quick and laborious breathing, and frequent pulse; and, in two hours more, he died. The body was not examined. In the same journal, Dr. Wells has described the case of a gentleman, subject to cough and dyspnoea, who awoke one morning with a severe pain in the left arm; In the afternoon it became be- numbed and paralytic. The pain then ceased, and the arm was found to be without pulse. He continued in this state for two days, without any other complaint; and on the third day, he died suddenly, as he got up to go to stool. The pa- ralytic arm only was examined after death, and in it no mor- bid appearance could be detected. This singular affection was probably connected with ex- tensive disease of the arterial system. Some years ago I saw a woman, aged 73, who was suddenly seized with violent pain of the whole right arm, accompanied by palpitation of the heart, inclination to vomit, and pain extending across the tho- rax from the breast to the back; the pulse of the affected arm was extremely weak; in the other arm it was 120 and strong, but irregular. After a day or two the pain ceased, leaving the arm without pulse, and very weak, but not completely pa- ralytic. After ten days, the right thigh and leg were affected in the same manner; after five days more, the left arm, and ten days after this, the left thigh and leg went through the same course. She was then confined to bed in a state of ex- treme weakness, and no pulsation could be felt in any artery except the carotids, and a little in the right humeral; in the carotids it was strong and frequent. The radial artery felt GENERAL PATHOLOGY OF PARALYSIS. 235 under the finger like a firm cord, as if permanently distended with blood. She still had pain in the region of the heart, which at times was very severe, impeding respiration, and preventing her from lying on the left side. She lived a month in this state; the dyspnoea and palpitation became gradually more and more severe ; and she died, gradually exhausted, two months after the commencement of the disease. Some days before death, slight pulsation was perceived in the arte- ries of the left arm, and in the right it was more distinct than formerly. On inspection much fluid was found in the peri- cardium, and in the right cavity of the pleura. The heart was flaccid, and none of its cavities contained any blood; in the right sinus venosus, there were two firm fleshy tumors or poly- pi ; the one the size of a pigeon's egg, attached to the side of the sinus by a slender pedicle, the other smaller and attached more extensively. The whole arterial system was extensive- ly ossified ; in some places the diameter of the artery was considerably diminished by the ossification, and several of the great arteries were completely obstructed by firm coagula of blood in the contracted parts. This was most remarkable in the right common iliac, which was filled through nearly the whole extent of the common trunk, by a dark coloured coagu- lum, which was firm, elastic, and dry. The left subclavian was also much diseased and considerably contracted, and the aorta near the bifurcation was for about two inches almost en- tirely ossified. There are other singular facts which seem to indicate pe- culiarities in the circulation in particular parts of the body, probably originating in the obscure relation betwixt the vas- cular and nervous systems. An esteemed medical friend of mine, now no more, when heated by exercise, perspired very freely on one-half of his body and not on the other, the line being drawn with great precision from the forehead along the ridge of the nose, and so downwards. When he was very much heated, the other side perspired also, but this only oc- curred occasionally, from great exertions ; the singular per- spiration of the one side was a matter of almost daily observa- tion. I knew another gentleman who had the same peculiari- ty, after being affected with complaints in the head, which had threatened a paralytic attack. Sir Everard Home has mentioned a man who had palsy of the lower extremities from a wound of the spinal cord ; there was free perspiration of all the parts above the seat of the injury, but none below it. The 236 GENERAL PATHOLOGY OF PARALYSIS. same peculiarity occurred in a remarkable manner in a case of disease of the spinal cord to be afterwards described. A child, mentioned by Dr. Falconer, became pale and emaciated on the whole left side of the body, without any diminution of muscu- lar power, the right side remaining healthy; she recovered by the use of warm pumping.* The various forms of comatose affections which have been described by systematic writers, seem to be merely varieties in degree, or modifications of the disease, of little practical importance ; but some of these conditions are deserving of at- tention. The state of lethargy, for example, presents some interesting phenomena, in regard to the extent in which it may exist without passing into apoplexy, and without permanent- ly injuring the functions of the brain, though they are for a time completely overpowered and suspended. A man, men- tioned by Mr. John Bell, who had been accustomed to a life of much activity, was confined from his usual employment by an extensive fistula which he had concealed. Being of a full habit, and his appetite unimpaired, he soon sunk into a state of complete lethargy, nearly his whole time being spent in sleep. When roused, he attempted to answer questions, but his answers were incoherent, and his speech inarticulate ; he had been a long time in this condition when Mr. Bell saw him. His fistula being cured, he recovered gradually by eva- cuations, blistering on the head, and a proper regulation of his diet, so that in a few weeks he was well, returned to his former employments, and managed with correctness the af- fairs of a company.f Hippocrates mentions a priest, subject to annual fits of gout, in whom the paroxysm terminated re- gularly for several years in a state of lethargy, from which he could only be roused to take food or drink. It was accom- panied by tremors, stupor, and forgetfulness, immobility of the eyes, and a completely enervated state of the whole body ; it generally continued one or two weeks. A man, mentioned by Willis, at the crisis of a putrid fever, lay for four days in a state of profound sleep, from which nothing could rouse him. He then came out of it after blistering, but his faculties were gone, so that he knew nobody, remembered nothing, and un- derstood nothing, " vix supra brutum saperet." He continued in this state for two months, and then gradually recovered.— Some years ago I saw a young man, who, at the end of a te- * Mem. Med. Soc. of Lon. vol. ii. f Bell's Principles of Surgery, vol. ii. GENERAL PATHOLOGY OF PARALYSIS. 237 dious fever, fell into such a degree of stupor that I apprehend- ed effusion in the brain. He recovered, however, after a good many days, and his bodily health was soon restored, but his mind was in a state approaching to idiotism. In this con- dition he was taken to the country, and recovered gradually after several months. A most remarkable case of this kind is related by Dr. Pritchard, on the authority of the late Dr. Rush, of Philadelphia. The patient was an American student, and a person of considerable acquirements, who, on his recovery from fever, was found to have lost all his acquired knowledge. On recovering his health, he began to apply to the Latin grammar; had passed through the elementary parts, and was beginning to construe, when one day, in making a strong ef- fort to recollect a part of his lesson, the whole of his lost im- pressions suddenly returned to his mind, and he found himself at once in possession of all the acquirements that he possess- ed before his illness. A state of the mental faculties somewhat analagous occa- sionally occurs in diseases of simple exhaustion. Many years ago, I attended a lady, who, from a severe and neglected diarrhoea, was reduced to a state of great weakness, with re- markable failure of her memory. She had lost the recollec- tion of a particular period, of about ten or twelve years. She had formerly lived in another city, and the period of which she had lost the recollection was that during which she had lived in Edinburgh. Her ideas were consistent with each other, but they referred to things as they stood before her re- moval. She recovered her health after a considerable time, but remained in a state of imbecility resembling the dotage of old age. The state of the brain in such cases as these differs from apoplexy, but is nearly allied to it; for a similar condition of the mental faculties sometimes occurs as a prelude to apo- plexy, or it may be left as a consequence of it, after every other symptom has been removed. A gentleman, mentioned by Wepfer, was seized with hemiplegia of the right side and profound sleep; in the second day, the right side was con- vulsed, and after this the palsy disappeared. He then lay in a state of sleep for nine days, having during seven of these been incapable of taking any food. On the 8th day he began to take what was offered, to him, and, on the 9th, he came out of the state of stupor, but his faculties were gone; he knew 238 TREATMENT OF APOPLEXY. nobody, and neither remembered nor attended to any thing. After several weeks he began to know his more particular friends, then began to remember words, to repeat the Lord's prayer, and to read a few words of Latin, rather than German, which was his own language, but only a fev? words at a time. If he was urged to read more, he said that he formerly under- stood these things, but now did not. He could write, how- ever, and frequently wrote lines both of German and Latin words, in elegant characters, hut without meaning. After some time he began to pay more attention to what was pass- ing around him, and to look after his household affairs. He often lamented his want of understanding, and expressed his hope that he should recover it. While thus making slight and gradual progress, he was, after three or four months, cut off by an attack of apoplexy. SECTION IV. OUTLINE OF THE TREATMENT OF APOPLEXY. From the facts which have been related, we have seen rea- son to believe, that there is a modification of apoplexy which fatal is without leaving any morbid appearance, and which, probably, depends upon a deranged condition of the circu- lation in the brain ; we hive also seen grounds for believing, that the cases which terminate by effusion are probably, at their commencement, in this state of simple apoplexy. We have seen farther, that we have no certain mark by which we can ascertain the presence of effusion ; and finally we have found, that even extensive extravasation of blood in the brain may be entirely recovered from by the absorption of the co- agulum. These considerations give the strongest encourage- ment to treat the disease in the most active and persevering manner. They teach us, also, not to be influenced in our practice, by the hypothetical distinction of apoplexy into san- guineous and serous; and finally, not to be hasty in conclud- ing in any particular case, that the disease has passed into a state in which it is no longer the object of active treatment. In the treatment of apoplexy, our remedies are few and TREATMENT OF APOPLEXY. 239 simple. Those in which our chief reliance is to be placed are, large and repeated bloodletting, active purgatives, and cold applications to the head, aided by an elevated position of the body, cool air, and the absence of all stimuli. Antimonials may occasionally be useful as an auxiliary, from their known effect in restraining vascular action, provided in the early stages they do not occasion vomiting. Our first great object is to take off the impulse of blood from the arteries of the head by bleeding carried to such an extent as shall powerfully and decidedly effect the system, and by^repeating it at short intervals as soon as these effects begin to subside. The first bleeding should probably be from the arm, but, after this, there seems to be an evident advantage in ab- stracting blood locally, either from the temporal artery or by cupping. Much importance has been attached by some to bleeding from the jugular vein, as most likely to give imme- diate relief to the head; but we must remember, that the only jugular vein that can be opened is the external jugular, which has very little communication with the brain, and consequent- ly that bleeding from it is probably much inferior to bleeding from the temporal artery. As soon as possible after the bleed- ing, means are to be taken for inducing strong purging. The most efficient remedy by far for this purpose is the croton oil, and if the patient cannot swallow, it may be very convenient- ly introduced into the stomach, suspended in thick gruel or mucilage, through an elastic gum tube ; the operation should be expedited by strong purgative injections. This is always to be considered as a most important and leading point in the treatment of apoplexy ; and though, in arresting the progress of the disease, our first reliance is upon large and repeated bleeding, the first decided improvement of the patient is gene- rally under the influence of powerful purging. The effectual application of cold to the head is the third remedy on which we rely, and it is equally applicable to the different states of the disease, whether arising from simple apoplexy or from ex- travasation. It may be applied either by means of iced wa- ter, or pounded ice in a bladder; or by a full stream of cold water directed against the crown of the head, and received in a basin held under the chin, while the patient is supported in a sitting posture. I have formerly given an example of a pa- tient restored in a few minutes or rather seconds by this reme- dy from a state of perfect apoplexy. The active use of these remedies is sometimes followed by 240 TREATMENT OF APOPLEXY. a very speedy removal of the apoplectic state. In other cases, though little immediate effect may be produced, yet by a per- severing repetition of them, the coma begins to subside after some time, perhaps a good many hours, or even several days. In other cases again, they may be used in the most active manner without relieving the patient, and after all we may find upon dissection, that the disease was still in the state of simple apoplexy. This important fact cannot be too often re- peated or too carefully kept in mind ; and it should lead us to prosecute the treatment of every case of apoplexy with the utmost vigor and perseverance. In one case that occurred to me, the bleeding was repeated to the extent of upwards of one hundred ounces, assisted by purging from the croton oil, repeated to the extent of above twenty drops, and the case ter- minated favourably, after the symptoms had continued in a very doubtful state for three or four days. In the extent of our evacuations, indeed, a due regard is certainly to be had to the age and constitution of the patient, and the strength of the pulse ; but I think we have sufficient ground for saying, that there are no symptoms which charac- terize a distinct class of apoplectic affections, requiring any important distinction in the treatment; or in other words, a class, which in their nature do not admit of bloodletting. On this important point, we may refer with some confidence to the facts which have been related. Weakness of the pulse, and paleness of the countenance, we have seen to be frequent symptoms of the worst form of sanguineous apoplexy; and on the other hand we have seen cases terminate by serous ef- fusion, which were accompanied by strong pulse and flushing of the countenance. Finally, we have seen one remarkable case in which there existed every circumstance that could lead us to consider the disease as serous apoplexy, but which was fatal without any effusion; and another in which there was most extensive effusion without any apoplectic symptom.— It is likewise to be kept in mind, that in apoplectic affections the strength of the pulse is a very uncertain guide, for nothing is more common than to find it upon the first attack of apo- plexy, weak, languid, and compressible, and becoming strong and full after the brain has become in some degree relieved by large bloodletting. It would be quite superfluous to detail common apoplectic cases treated successfully upon these principles. But it may be of use, in connexion with this part of the subject, to select TREATMENT OF APOPLEXY. 241 a few cases, which, occurring in old and infirm people, might have been considered either examples of serous apoplexy, or modifications of the disease not admitting of active treatment, yet under such treatment terminating favourably. Case CXXXVI.—A woman aged 70, of a spare habit, and thin and withered aspect, having walked out in her usual health, fell down in the street, speechless and paralytic on the right side. I saw her four or five hours after the attack. She was then much oppressed, but not entirely comatose. She was completely speechless and paralytic ; her pulse about 96, and of tolerable strength. She was bled to 15 ounces ; purgative medicine was ordered, with cold applications to her head. On the following day she was considerably improved both in speech and in the motion of the right side ; but, having be- come rather worse towards night, she was again largely bled, and purgative medicine was continued. From this time she improved rapidly. At the end of a week she was able to walk with little assistance, and in a few days more was restored to perfect health. Case CXXXVII.—A gentleman aged 70, of a spare and feeble habit, and very infirm from frequent attacks of asthma, without any warning fell from his chair on the floor in a state of perfect apoplexy, accompanied by violent convulsion. When I saw him, an hour after the attack, he was still in a state of perfect coma; the convulsion had recurred at short intervals, and had affected chiefly his arms and his face. His face was pale; his pulse was of good strength and a little frequent. He was largely bled from the arm; and an active purgative was given, assisted by a purgative enema, and cold was ap- plied to his head. The convulsions continued for some time to recur with great violence ; they then became less severe, and at length ceased about three hours after the attack, leaving him in a state of coma. But the purgative having soon after operated freely, he recovered his recollection. Next day, he complained of headach, and took more purgative medicine; and after a few days more he was in his usual health. Case CXXXVIII.—A lady aged 82, on the morning of Sunday, 8th March, 1818, complained of headach, but "went to church. While in church she lost her recollection, talked incoherently, and was brought home with difficulty, being 242 TREATMENT OF APOPLEXY, una*ble to stand. She was still incoherent and partly coma- tose ; and when put to bed was seized with violent convul- sion, which affected chiefly her face and the left side of her body. The convulsions recurred frequently, leaving her in the intervals in a state of profound coma, and the left side ap- peared to be paralytic. The pulse was of good strength, and a little frequent. She was bled to 20 ounces ; cold was ap- plied to her head, and an active purgative was given as soon as she could swallow. On the following day there was little change ; more purgative medicine was given. On the 10th the coma was diminished, but it was succeeded by much un- manageable restlessness with incoherence and some convul- sion ; pulse 112. More purgative medicine was given; and small doses of the tartrate of antimony seemed to be very be- neficial. On the 11th there was little change, but on the 12th she was much improved—began to know her friends, and her pulse was coming down. In a few days more she was in her usual health, and lived for several years. This lady had also suffered an apoplectic attack in 1814. Case CXXXIX.—A man aged 70, tall and of a spare ha- bit, and rather infirm—10th April, 1815—lost his recollection ; walked unsteadily without knowing whither he was going, and could not be made to comprehend that he was ill. He was put to bed, but insisted upon getting up again, staggered a few steps, and then fell down on the floor in perfect apo- lexy. I saw him about an hour after the attack, when he was still in a state of profound coma; his pulse a little frequent and of good strength. Being bled to 25 ounces, he became sen- sible, and took purgative medicine ; and his head was shaved and blistered. After three hours he relapsed into coma. He was then'bled again to 15 ounces without any immediate re- lief, but, the purgative having soon after begun to opera'te briskly, he was gradually relieved ; and in a few days was free from complaint. By bloodletting and the other evacuations, we cannot per- haps properly be said to cure apoplexy; we only relieve the vessels of the brain from the impulse of the general circulation, and thus take off one principal impediment to the recovery, which consists in the vessels resuming their healthy relations after this impediment is removed. But we have every reason to believe, that these evacuations may be carried as far as they TREATMENT OF APOPLEXY. 243 can with propriety, and yet that the vessels may not recover their healthy action. Having therefore pushed these evacua- tions as far as we consider safe or expedient, without relieving the patient, our next object is to inquire, what other means we have in our power which may contribute to his relief un- der these circumstances. Blistering and other external stimu- lants may perhaps have some effect, and I think I have seen decided benefit from strong friction of the body, but these re- medies are perhaps not much to be relied on. There are how- ever two remedies, which have been at different times strongly contended for in the treatment of apoplexy, and which may come under consideration, at that period or in that condition of the disease which I have now referred to; these are, eme- tics and internal stimulants. The use of emetics in apoplexy is as old as the days of Aretaeus, and they have been employed at different times by physicians of the first eminence, among whom may be mentioned, Etmuller, Sydenham, Boerhaave, and Lieutaud; and the practice must therefore have some foundation in observation and experience. There can be lit- tle doubt that in the early stage of any apoplectic affection, the use of an emetic would be a very hazardous practice, and, at any period of apoplexy with extravasation of blood, it pro- bably would be injurious; but in simple apoplexy, after the system has been reduced by repeated evacuations as far as seems expedient, and yet the coma has not been removed, it seems very probable that the action of a mild emetic might be beneficial. The delicacy of the practice, however, consists in the difficulty of distinguishing simple apoplexy from apoplexy with extravasation of blood. Nearly the same observations apply to the use of internal stimulants. We must make an important distinction betwixt the action of stimulants in a vi- gorous and plethoric state of the system, and their action when the system has been reduced by large and repeated evacua- tions ; and I think there are conditions of apoplexy in which stimulants may be used with safety and advantage. The observations which have now been made, in regard to apoplexy, apply equally to the earlier stages of paralysis. In regard to the more advanced cases, after the immediate effects of the attack have been removed, there are some very inte- resting points of investigation. Perhaps we have been too much in the habit of believing that paralysis of any considera- ble standing depends upon a fixed and irremediable disease of the brain. Many cases are on record which tend to shake 244 TREATMENT OF APOPLEXY. this opinion. We see recent cases of it completely carried off in a few days; we see others recover more gradually, so that, in a few weeks or months, there is no trace of the dis- ease ; and in many cases, in which, after long-continued palsy, the patient has died of some other affection, we find no mor- bid appearance in the brain, or none adequate to account for the disease. We may add to these facts many singular ex- amples of very sudden recovery from palsy even in cases of long standing. A man, mentioned by Dr. Russel,* after an apoplectic attack with hemiplegia, recovered the use of his arm in six weeks, but the lower extremity remained perfectly paralytic. After twelve months, in which he made no im- provement, he was one day astonished to find that he had some degree of motion of the leg, but it continued only a few minutes. On the same evening he had headach, and in the night he was seized witha sort of fit in which the paralytic limb was strongly convulsed, and after this he had slight power of moving it. The fit returned next day, and again in the night, and then left him completely free from paralysis, and in perfect health; he had continued well for eight years at the time when the account was written. A case somewhat simi- lar, though of shorter standing, occurred to a friend of mine. A middle-aged man was suddenly attacked with hemiplegia and loss of speech, while he was using violent exercise in walking quick or running; all the usual practice was employ- ed without any improvement for a month ; the paralytic limbs then became one day suddenly convulsed, "and when this sub- sided the paralysis was gone. In a woman, mentioned by Dr. Home, hemiplegia of considerable standing was removed by an attack of fever, f A man whose case is mentioned by Mr. Squire,| had been liable to convulsions from his childhood till he was twenty- three years of age. The fits then left him, and he enjoyed good health for three years; when, without any previous com- plaint, except a cold, he suddenly lost his speech. He had no other paralytic symptom, and was otherwise in good health, but continued perfectly speechless for four years. He was in general a man of temperate habits, but having at this time been one evening much intoxicated, he fell from his horse three or four times on his return home, and was at last taken * London Med. Observ. and Enq. vol. i. J Home's Clinical Experiments. t Philosophical Transactions, vol. xlv. TREATMENT OF APOPLEXY. 245 into a house near the road and put to bed. He soon fell asleep, and had a frightful dream, during which, struggling with all his might to call out for help, he did call out, and from that time recovered his speech perfectly. A young wo- man, mentioned by Dr. Watson,* had been long liable to se- vere convulsions, the attacks of which were frequently follow- ed by temporary paralysis of those muscles which had been most severely affected. After one attack she lost her sight entirely for five days. At length, after one of the fits, she lost her speech, and recovered it after a short time; but the convulsion returning soon after, was again followed by loss of speech, and she continued entirely speechless for four- teen months. During this interval she had no return of the convulsion, and was otherwise in good health. Having one evening violently heated herself by dancing for four hours, she recovered her speech, and from that time continued free from complaint. Several cases still more remarkable are related by Diemerbroeck.f A woman, who had been paralytic from the age of six to forty-four, suddenly recovered the perfect use of her limbs, when she was very much terrified during a severe thunder-storm, and was making violent efforts to escape from a chamber in which she had been left alone. A man, who had been many years paralytic, recovered in the same manner when his housfe was on fire; and another, who had been ill for six years, recovered suddenly in a violent paroxysm of anger. A. remarkable case has been communicated to me of a gen- tleman, who, after an apoplectic attack lost his sight, and continued in a state of perfect blindness for about seven years. After that time, while he was one day out in his carriage, he suddenly recovered his sight; and it was found that he had entirely retained his skill in drawing, for which he had been distinguished before the attack. These examples point out a most important principle in re- gard to paralysis, namely, that cases of it, even of long stand- ing, sometimes depend upon a cause which is capable of being removed entirely, and removed almost in an instant; and they direct our attention to a most interesting subject of research in regard to a class of affections, which of all diseases are usually considered as the most hopeless. The restoration of paralytic limbs, after the first urgency of " Philosophical Transaction?, vol. i. t Observat. et Curationes Medicse. Obs. X. 246 TREATMENT OF APOPLEXY. the attack has been removed, is in many cases entirely a work of nature, and seems, in the most common description of cases, to depend upon the gradual absorption of the coagulum. In the treatment of cases of a more protracted kind, various remedies have been employed, chiefly of a stimulating nature, both external and internal. To the former class belong warm baths, friction, electricity, and galvanism; to the latter, mus- tard, ammonia, camphor, and nearly the whole class of stimu- lants. All the remedies of this class, however, must be used with a considerable degree of caution ; perhaps the use of them may be more safe, and may be carried on with a greater de- gree of activity, if the general system, at the same time be kept in a very low state by spare living and occasional eva- cuations. This, I imagine, is always to be considered as an essential part of the treatment, and I cannot agree with some most respectable writers, who hold that the diet in paralytic cases ought to be nourishing and restorative. With this pre- caution, I think it probable, that there are many cases of pa- ralysis in which stimulants may be employed with much bene- fit. I cannot say what remedies of this class are to be pre- ferred. Some have strongly recommended the tincture of Cantharides, others have employed the balsams, turpentine, mustard, arnica montana, guaiacum, seneka, and various others ; also several articles of a narcotic quality, as the Rhus toxicotendron, Aconitum napellus, &c. In Germany, phos- phorus is said to have been given internally with advantage; and the favorite remedy lately has been the strichnia. It is apt to occasion convulsion, and the first proposal of the use of it as a remedy, is said to have been founded on the obser- vation, that when paralytic limbs become convulsed, they fre- quently soon after recover their power. In the most favorable examples, however, that have been given of its efficacy, a long time was required for the recovery; and as we know that a considerable proportion of paralytic limbs recover spontane- ously, we must receive very cautiously the statements in re- gard to the efficacy of any particular remedy. M. Gendrin states, that he has had extensive experience in the use of the strichnia, in all its forms, and the result of his observation is qertainly not encouraging. In all his cases it exercised an immediate and powerful influence,—producing a sense of heat and formication in the limbs, and spasmodic contractions, which were, in some cases, general, in others confined to the paralytic limbs. These effects were continued for weeks, and, TREATMENT OF APOPLEXY. 247 in most of the cases, were repeated several times, but no di- minution of the palsy was observed in any of them. Emetics have been recommended; also iodine and mercury pushed to salivation. Mr. Wardrop has described a singular case of eighteen months standing, which seemed to derive benefit from tickling the parts with a feather; it recovered in two months. M. Gross mentions a cure by stinging with nettles ; and Celsus seems to have employed a similar practice. In the treatment of paralytic limbs, however, we can expect to do nothing, unless the cause be removed, and their recove- ry after the cause has been removed, is chiefly to be regard- ed as the work of nature. As auxiliaries, it is probable, that, in general, we can employ nothing better than much dry friction, and particularly persevering exercise of the limbs themselves, as soon as they have recovered the slightest de- gree of motion which shall make them capable of it.* * For a variety of important matter relating to the whole subject of apoplexy and palsy, see the learned work of Dr. Cooke, "on Nervous Diseases and on Palsy. APPENDIX TO PART SECOND. CONJECTURES IN REGARD TO THE CIRCULATION IN THE BRAIN. In our preceding investigations on the pathology of apo- plexy, every attention has been paid to confine the observa- tions that were offered, to a direct induction from the facts which were before us. Nearly connected with these investi- gations, however, there are certain views relating to the cir- culation in the brain, which perhaps may be regarded as le- gitimate conjectures. I place them in this manner distinct from the other parts of the inquiry, because they cannot be considered as entirely divested of hypothesis. When a person previously in good health falls down sud- denly in a state of perfect apoplexy, and when, the appro- priate treatment being promptly applied, this person is speedi- ly restored to perfect health, it is impossible not to feel the deep interest of the inquiry,—what the state of the brain was which produced symptoms of so formidable a kind, and yet was so speedily and so entirely removed. If the patient shall die after lying for a considerable time in a state of perfect coma, and we cannot discover in his brain the smallest deviation from the healthy structure, we feel in no small degree the in- creasing interest of the inquiry. It is probable that the source of these remarkable derangements in the brain, in as far as it is within our reach, is to be sought for in an interruption of ON THE CIRCULATION IN THE RRAIN. 249 the due relations which ought to exist betwixt the arterial and venous system of the brain. On this subject there are certain principles which appear to result from peculiarities in the structure of the head, and which do not apply to any other organ in the body. The facts, on which this investigation is primarily founded, are derived from the appearance of the brain in animals which have been bled to death. While in such eases all the other organs of the body have been found completely blanched or drained of blood, the brain has in general presented in this respect its usual appearance, and, in some cases, the superfi- cial cerebral veins have even been found in so distended a state, that one writer has proposed the paradox, that animals which have been bled to death, die of apoplexy. The most able and most satisfactory observations on this subject are those of the late Dr. Kellie of Lieth,* made upon animals bled to death under a variety of circumstances. The brain in most of these cases, presented its usual appearance, its blood-ves- sels being well filled; while in others, the appearances were still more remarkable. In one, the sinuses were loaded with dark blood, and the vessels of the pia mater were delicately filled with florid Mood. In another the sinuses were loaded with blood, the veins of the pia mater were well filled, and the choroid plexus was remarkably turgid. In a very few only of the examples it is remarked, that the vessels of the brain contained sensibly less red blood than in the other cases, and in all of these there was observed some serous effusion. On the other hand, when these experiments were repeated on other animals after a small opening had been made in the cranium by the trephine, the brain was found as much drained of blood as any other part of the body. Dr. Kellie adds to these experiments, an account of observations which he made along with Dr. Monro, on the brains of two men that had been hanged. On dividing the scalp, in these cases, the blood flowed in such quantities as to afford ample proof of the con- gestion in the vessels exterior to the cranium, but nothing un- usual was observed in the brain. " The sinuses contained blood, but in no extraordinary quantity; the larger vessels on the surface, and betwixt the convolutions, were but moderate- ly filled, and the pia mater was, upon the whole, paler and * Transactions -of the Medico-Chirurgical Society of Edinburgh, vol. i. Besides llie experiments alluded to, I refer to this valuable communication for a variety of most interesting facts and speculations in regard to the whole of this curious subject. 250 ON THE CIRCULATION IN THE BRAIN. less vascular than we often find it in ordinary cases."—To these important facts I have only to add another of a very in- teresting nature, mentioned by M. Gendrin. With the assis- tance of M. Beclard, he examined minutely the brains of two persons who had been put to death by decapitation ; and they were both greatly astonished at the turgid state of the cere- bral vessels, which they had expected to find empty. These remarkable facts lead our attention to certain pecu- liarities in the structure of the head, to which they may proba- bly be traced in a very satisfactory manner. The cranium is a complete sphere of the bone, which is exactly filled by its contents, the brain, and by which the brain is closely shut up from atmospheric pressure, and from all influence from with- out except what is communicated through the blood-vessels which enter it. In an organ so situated, it is probable, that the quantity of blood circulating in its vessels cannot be ma- terially increased, unless something give way to make room for the additional quantity, because the cavity is already com- pletely full; and it is probable, that the quantity cannot be materially diminished, unless something entered to supply the space which would become vacant. In this investigation it is unnecessary to introduce the question, whether the brain is compressible, because we may safely assert that it is not compressible by any such force as can be conveyed to it from the heart through the carotid and vertebral arteries. Upon the whole then I think we may assume the position as being in the highest degree probable, that, in the ordinary state of the parts, no material change can take place in the absolute quantity of blood circulating in the vessels of the brain. But the blood circulating in these vessels must be divided in a certain ratio betwixt the arteries and veins of the brain; and it is probable that the healthy state of this organ will de- pend upon the nice adjustment of the circulation in these two systems. If we could suppose a case in which more than the usual quantity of blood was accumulated in the one system, the necessary effect would be a corresponding diminution in the other, because the whole mass of blood in the brain must, by the supposition, remain the same. Hence would arise a derangement of the circulation, such as could not occur in any other part of the body, because there is no other organ so situ- ated as the brain. We must be cautious, however, of specu- lating, where it is difficult to avoid falling into error, and must satisfy ourselves with attempting to trace, in a very ge- ON THE CIRCULATION IN THE BRAIN. 251 neral manner, the various ways by which, in such an organ as the brain, derangements of circulation may be supposed to take place. I. Let us suppose a very plethoric state of the body, in which the general vascular system is loaded with more than the average or healthy quantity of blood. The arteries going to the head will partake of this general condition, and there will be an effort or impulse which tends to propel an undue quantity of blood into the arteries of the brain. Though no addition to the whole quantity of blood in the brain can actu- ally take place, because the vessels of the brain are already full, the constant impulse will be such as tends to introduce an additional quantity, and consequently tends to derange the healthy relation betwixt the arterial and venous sys- tem ; for any increase of quantity in the one system could not take place without any corresponding diminution of the quantity in the other. Let us say, for example, that the whole blood circulating in the brain is as ten, and that it is divided between the arteries and veins as five to five. In the loaded state of the system now referred to, we can suppose a case, in which, by some sudden impulse from the general circula- tion, the arteries of the brain are, at a particular moment, distended by a quantity as six. In any other part of the body this would be followed by a similar distension of the corres- ponding veins, and the healthy balance of the circulation would be speedily restored. But in the brain the very reverse would happen; for as the whole mass of blood must continue as ten, if the arteries were thus distended by a quantity as six, the quantity in the veins must be, by the same impulse, dimi- nished to four, because the increased capacity in the one system of vessels, can be gained only by an instant and correspond- ing diminution of capacity in the other. The result of the condition so produced would be the following. The arteries of the brain would contain a quantity of blood as six, while the veins would contain and could transmit a quantity only as four. The quantity transmitted by the veins would then be the measure of the quantity that could enter the arteries from , the general circulation, namely, a quantity as four. But the impulse from the general circulation would be such as tended to introduce a quantity as six, supposing the continuance of the undue impulse from which the disease originated, or a quantity as five, supposing the impulse to have subsided to 252 ON THE CTRCTULATTON IN THE BRAIN. the state of health. In either case the impulse would be such as tended to introduce a greater quantity than could enter, and consequently to keep up the deranged state of the cere- bral vessels which had taken place. The farther result of this would be, an increased flow of blood into the external vessels of the head, producing probably flushing, turgidity of features, and other marks of increased determination to the external parts. I am aware that this is hypothetical and con- jectural; but from the nature of the subject, our speculations respecting it must ever remain so. Various facts have been stated, and others remain to be mentioned, which give the conjecture a considerable degree of probability; and it appears to be the nearest approach we ean make towards a distinct conception of that condition to which we give the name of eonjestion in the brain. II. If there be any considerable interruption to the return of the blood from the veins of the brain, a derangement will take place very analogous to that supposed under the former head. If the quantity of blood which is actually returned by the veins be considerably diminished, there will be a corres- ponding diminution of the qualities which can enter the arte- ries. The healthy impulse from the general circulation will then become, in reference to the actual state of the circulation in the brain in this ease, what the undue impulse was in the other. But I forbear from urging the inquiry, whether such a derangement as we have now supposed might take place from causes retarding the return of blood from the head, such as tumors on the neck, and certain affections of the heart and lungs; and whether, if it did take place, it might give rise to symptoms analogous to simple apoplexy. Two points, however, may be briefly alluded to in regard to the parts of this speculation, referred to under the two pre- ceding heads. (1.) If such a derangement, as has been sup- posed, really took place in the vascular system of the brain, it would follow, that the impetus from the general circulation would be such as tended to introduce into the arteries of the brain a larger quantity of blood than could actually enter. One effect of this would be an increased flow of blood into the external vessels of the head, and there are various facts which tend to show that something of this kind does actually take place in the apoplectic attack,—as the flushing of the face, turgidity of the features, throbbing of the external vessels, and ON THE CIRCULATION IN THE BRAIN. 253 other appearances which have been referred to the doctrine of determination to the head. Numerous writers have remarked the unusual quantity of blood which is discharged from the integuments, in opening the heads of persons who have died of apoplexy. In some of Dr. Cheyne's dissections, upwards of a pound was collected in this manner; and Dr. Kellie made the same observation on the two men whom he examined after execution. Mr. John Bell remarks, that having injected the head of a person who died of an affection of the brain, he found the features so distorted by the injection, the lips so protruded, and all the superficial vessels so much enlarged, as to make the preparation useless. The remarkable turgidi- ty of the features and of the neck, which often occurs in a- poplectic cases, must indeed be familiar to every one; and it appears to be most remarkable when the disease has proved rapidly fatal, without any means having been employed. A gentleman whom I saw with Mr. WTiyte, after some symp- toms showing an apoplectic tendency, was one morning found dead in bed, his body being scarcely cold. His neck and features were of a deep purple colour, and turgid in a most uncommon degree, but no turgidity was observed in the ves- sels of the brain. (2.) Upon the grounds already referred to, there is reason to believe, that we cannot, by our evacuations, diminish in any material degree the quantity of blood in the head. But if these conjectures shall be considered worthy of any credit, it will appear probable, that the effect of our eva- cuations will be to take off from the cerebral vessels, the ex- cessive impulse from the general circulation, or even to reduce it below what would now be considered as a healthy impetus, and thus to leave the vessels of the brain in a state favourable for recovering their healthy relations. III. A similar derangement might be supposed to take place from causes which directly diminish the capacity of the venous system of the brain. If a depression has been pro- duced of a portion of bone, so as considerably to encroach upon the cavity of the cranium, or if a coagulum of blood has been deposited, so as to occupy a considerable space upon the surface of the brain, the diminution of space thus produced would probably affect chiefly or entirely the venous system of the brain, the veins being in general more superficial, and more immediately exposed to the pressure, than the arteries. It would not diminish the quantity of blood which tends to 254 ON THE CIRCULATION IN THE BRAIN. enter the arteries of the head, but it would diminish in pro- portion to its extent the capacity of the veins, and thus de- range the relations betwixt the two systems of vessels, in a different manner from that which has been supposed under the former heads, but analogous in its effects upon the circulation of the brain. When, in the former cases now supposed, the depressed portion of bone has been elevated, the two systems recover their healthy relations, and the symptoms disappear. It is probable that a cause of this kind may exist in a smaller degree, in which it shall not produce any permanent interruption of the circulation in the brain, but may give rise to derangement when there is any occasional increase of im- petus in the circulation. In the first part of these essays, I have described a remarkable case, in which a tumor, formed by deposition betwixt the laminae of the dura mater, occupied a considerable space on the surface of the brain. The patient had experienced little inconvenience from it when he was at rest, but, when in motion, he was liable to attacks of an apoplectic nature, from which he recovered in a few minutes. A gen- tleman, mentioned by Lancisi, who had long suffered from hemicrania, was seized about the age of 50 with intense pain in the temple, and soon after had an attack of apoplexy, from which he speedily recovered; but from this time he had an apoplectic attack once or twice every month. This went on through the following autum and winter, and he at last died suddenly in one of the attacks. Under the right side of the os frontis, the membranes were much thickened, and connect- ed with the thickened portion there was a kind of polypus on the surface of the brain. In cases such as these, it is proba- ble, that, when the circulation is in a very tranquil state, or when the general mass of blood has been reduced by evacua- tions, the circulation in the brain goes on in a healthy man- ner ; but that any increase of the quantity of blood, or any considerable increase of its impetus, leads to the derangement. It is probable that similar affections might be traced to causes diminishing the area of the sinuses, or of the principal veins of the brain ; and I have formerly mentioned some remarkable cases, in which frequent attacks of an apoplectic and paralytic nature appeared to be connected with extensive disease of the arteries of the brain. Facts are wanting on this interesting subject; but many cases are on record in which an individual has suffered in a few years fifteen or twenty apoplectic attacks, without experiencing in the intervals any bad effects from ON THE CIRCULATION IN THE BRAIN. 255 them. Minute attention to such cases may probably lea 1 to results calculated to throw much light upon the pathology of apoplexy. IV. There are many interesting facts which lead us to be- lieve, that the circulation in the brain may be deranged in a manner remarkably different from any of the preceding cases. Let us suppose that the general volume of blood in the body is very much diminished. The effect of this upon each in- dividual artery is, that its calibre is contracted, and that it acts upon the veins with which it is connected with diminished momentum. The arteries of the brain will partake of the ge- neral state of the system, so that the quantity of blood trans- mitted to the head will be diminished in the same ratio. But while this change is going on, a corresponding accumulation would probably be taking place in the veins, because the whole quantity in the head must continue nearly the same. Upon this increased mass of blood in the veins, the volume in the arteries would now act with a correspondingly diminished and inadequate impetus. It is probably in this manner that there arises the appearance of congestion in the superficial veins of the brain, which have been observed in animals that have bled to death ; and many curious facts occur to us in practice, which appear to be referable to a derangement of the circula- tion in the brain, which can only be accounted for in this manner. I shall relate some of these facts without indulging farther in speculation. A gentleman aged about forty, had been for some time losing considerable quantities of blood by arterial haemorrhage from the rectum. Considering it as merely haemorrhoidal, he paid little attention to it, until his friends became alarmed by his altered appearance. From being strong and rather ple- thoric, he had become weak, exhausted, pale and haggard. He had anasarca of his legs,—his pulse was frequent and feeble, and much excited by the least exertion. Along with these symptoms, he was liable to strong and irregular action of the heart, and complained of giddiness, tinnitus aurium, violent throbbing in the head, and frequently of throbbing headach. On examining his rectum, a fungous tumor was found within the sphincter, on the apex of which a small ar- tery was bleeding per saltum. This was tied, and there was no return of the heemorrhage; and under the use of nourish- ing diet, and a liberal allowance of wine, all his other com- 256 ON THE CIRCULATION IN THE BRAIN. plaints disappeared. He made up so rapidly in flesh and blood, that not long after, apprehensions were entertained that he was becoming too plethoric, and it became necessary to reduce his regimen, but under these circumstances he had no return of the symptoms in his head. A lady aged twenty-five, had been frequently bled on ac- count of symptoms in the head which had supervened upon an injury. Considerable relief had followed each bleeding; but the symptoms had soon returned so as to lead to a repeti- tion of the bleeding at short intervals, and this had been going on for several months. When I saw her, she was stretched upon a couch, her face of the most death-like pale- ness, or rather of the paleness of a stucco figure, her pulse very rapid and as small as a thread, her general weakness extreme. The mass of blood appeared to be reduced to the lowest point that was compatible with life, but she still com- plained of frequent headach, violent throbbing in the head, confusion and giddiness. It was evident that evacuations could be carried no farther, and, in consultation with a very intelligent medical man who had the charge of her, it was agreed as a last experiment to make trial of the opposite sys- tem, nourishing diet and tonics. In a fortnight she was re- stored to very tolerable health. Under similar circumstances a friend of mine was called to visit a lady who had suffered from long-continued uterine haemorrhage. Her general aspect was that of great exhaus- tion, but she complained so much of throbbing in the head, that her medical attendants were treating her by evacuations and very spare diet. She was restored by nourishment and wine ; and as she recovered strength, the feelings in her head entirely disappeared. I have been repeatedly consulted under the following cir- cumstances. A gentleman accustomed to very full living, is seized with an apoplectic attack, or with symptoms indicating the most urgent danger of apoplexy ; he is saved by bleeding and other free evacuations, and is kept for some time upon a very spare diet His complaints are relieved, and as long as he keeps quietly at home, he goes on without any uneasy feeling. But when he begins to go abroad, he becomes liable to attacks of giddiness and confusion, generally accompanied by palpitation of the heart and an uneasy feeling about the praecordia. His pulse is now soft and rather weak, and his general appearance indicates the very reverse of plethora ; ON THE CIRCULATION IN THE BRAIN. 257 and these symptoms are removed by a cautious improvement of his regimen. This curious fact I have repeatedly had oc- casion to attend to in the treatment of cases of this kind, and it has always appeared to me one of very great interest in re- ference to the pathology of the brain. Various other facts will present themselves to the practical physician, which bear upon this curious subject. In the last stage of diseases of exhaustion, patients frequently fall into a state resembling coma, a considerable time before death, and while the pulse can still be felt distinctly ; and I have many times seen children lie for a day or two in this kind of stupor, and recover under the use of wine and nourishment. It is often scarcely to be distinguished from the coma which accompanies diseases of the brain. It attacks them after some continuance of exhausting diseases, such as tedious and neglected diarrhoea ; and the patients lie in a state of insen- sibility, the pupils dilated, the eyes open and insensible, the face pale, and the pulse feeble. It may continue for a day or two, and terminate favourably, or it may be fatal. This af- fection appears to correspond with the apoplexia ex inanitione of the older writers. It differs from syncope in coming on gradually, and in continuing a considerable time, perhaps a day or two ; and it is not, like syncope, induced by sudden and temporary causes, but by causes of gradual exhaustion going on for a considerable time. It differs from mere ex- haustion, in the complete abolition of sense and motion, while the pulse can be felt distinctly, and is in some cases of tolerable strength. I have seen in adults the same affection, though it is perhaps more uncommon than in children. A man considerably advanced in life, in consequence of a ne- glected diarrhoea, fell into a state closely resembling coma ; his face pale and collapsed, but his pulse of tolerable strength. An elderly lady from the same cause, had loss of memory and squinting. Both these cases recovered by wine and opiates ; in the former blistering on the neck was also employed. Richter states that amaurosis has been produced by haemor- rhage, cholera, and tedious diarrhoea; and he mentions par- ticularly a dropsical woman, who became blind when the fluid was evacuated from her abdomen by tapping. On this interesting subject, I shall at present only add the following remarkable illustration from an affection of hearing. A gen- tleman, about thirty years of age, came to Edinburgh from a distance for advice in regard to an obscure affection, referred 33 258 ON THE CIRCULATION IN THE BRAIN. chiefly to the stomach, which had reduced him to a state of extreme weakness and emaciation. As the debility had ad- vanced, he had become considerably deaf, and when I saw him he was affected in the following manner. He was very deaf while sitting erect or standing, but, when he lay hori- zontally, with his head very low, he heard perfectly. If, when standing, he stooped forward so as to produce flushing of his face, his hearing was perfect, and, upon raising him- self again into the erect posture, he continued to hear dis- tinctly as long as the flushing continued ; as this went off the deafness returned. Upon the whole, it seems highly probable that a certain balance of the circulation of the brain is necessary for the healthy condition of its functions ; that they are equally im- peded by the interruption which takes place in apoplexy, and the diminished impulse which occurs in syncope and in many affections of extreme exhaustion ; and that there is a remark- able similarity in the symptoms which occur in these opposite conditions. What indeed is syncope, but an abolition of sense and motion? It is preceded by giddiness, tinitus aurium, and impaired vision, and is accompanied by blindness, dilated pupil, perfect insensibility, and not unfrequently passes into convulsion. It differs then from apoplexy, chiefly or entirely in the state of the general circulation, the symptoms accom- panying the two affections being remarkably similar, and the effect upon the sensorial functions almost entirely the same. Here however some questions occur: If the circulation in the brain be so nicely and peculiarly balanced, why is it not seriously deranged by the numerous changes which are con- stantly occurring amid the variety of circumstances to which the body is exposed ? Why is not apoplexy produced by every increase in the mass of the blood, or why is it not ex- cited by every instance of intemperance, violent exercise, or strong mental emotion ? Is there any provision by which the effects of these causes are averted in their daily occurrence, though in a certain condition of the system, each of them may be capable of producing perfect apoplexy ? It seems probable that there are several circumstances in the anatomy of the head, which contribute to this important end, but I shall merely allude to them without entering upon the speculations to which they might lead. One is, that all the arteries of the brain enter the head through continued canals of bone. These appear to have considerable influence in arresting any sudden ON THE CIRCULATION IN THE BRAIN. 259 impulse of blood, and in directing it off to the external branches. Hence the flushing of the face, turgidity of the features, and throbbing of the external vessels, which often occur in such cases, while no affection of the brain follows. Another circumstance, which seems to contribute to the same purpose, is the peculiar structure of the sinuses of the dura mater. These at all times must contain a considerable pro- portion of the venous blood of the brain, and from their pe- culiar structure it seems probable that they are not liable to have their area either increased or diminished in any consi- derable degree. This remarkable structure must operate very considerably in preventing those derangements of the circu- lation which have been referred to. in the preceding specula- tions, and which, in an organ situated as the brain is, must oth^rwisp Kavp toVpn nlace from very slight causes. PART III. OF THE ORGANIC DISEASES OF THE BRAIN. By organic diseases of the brain we understand, either per- manent changes of the cerebral substance itself, or new for- mations within the head. These may be either imbedded in the substance of the brain, or attached to its surface. The principal forms under which we meet with these affections may probably be referred to the following heads: I. Tumors formed by the thickening of the membranes of the brain, or by deposition of new matter betwixt their lami- nae. Of this I have already given a very remarkable exam- ple, (Case VI.) in which a tumor five inches long, three inches broad, and half an inch in thickness, was formed in this man- ner by a deposition of new matter betwixt the laminae of the dura mater. II. Deposition of a pellucid or semi-pellucid substance hav- ing the characters of albumen. This may either be formed in undefined masses under the membranes of the brain, par- ticularly under the arachnoid, as in Case XCIL, or contained in distinct cysts in various parts of the brain, as in the Cases XC. and XCI. The substance which is deposited in these cases coagulates into a firm mass in the heat of boiling water. It is met with in various degrees of consistency, and there is some reason to believe that it undergoes remarkable changes in density, assuming a firmer texture in certain stages of its progress. III. A very dense tumor, of a uniform whitish or ash co- lour, and exhibiting the appearance of the properties of coa- gulated albumen. This substance is found in distinct round- ed tumors of various sizes, which are generally attached to the ORGANIC DISEASES OF THE BRAIN. 261 dura mater, and do not appear to be covered by any cyst. I have described one which grew on the falx in Case LXXXVIL, nearly five inches in circumference, and uniformly white and firm in its consistence; it did not appear to be organized, and when analized exhibited the properties of coagulated albumen. The remarkable circumstance in this case was, that no urgent symptoms arose from the presence of this mass until a few weeks before death. Tumors of this kind sometimes arise from the external surface of the dura mater; in this case they have been frequently known to produce absorption of the bone, and to rise externally under the integuments of the head, so as to be mistaken for wens. Many cases of this kind are mentioned by the French writers. In some of them, the dis- ease seems to have been originally excited by injuries; and in others, an injury appears to have accelerated the process by which the tumor was making its way through the bone. When these tumors have been rashly meddled with by incision, death has generally been the consequence. Small tumors, which resemble those of this class, are sometimes met with attached to the choroid plexus. I have seen one in each lateral ven- tricle, the size of small hazel-nuts, in a man who died sudden- ly after having had repeated epileptic attacks at long intervals, and having been for some time affected with symptoms threat- ening apoplexy. IV. Tumors externally resembling those of the former class, but internally presenting an organized appearance, and a red- dish or flesh-colour, resembling the substance of the kidney. These are met with in various situations ; one will be describ- ed, the size of an egg, which grew from the tentorium. The two appearances, described under this and the former heads, seem to include the most common characters of what may be properly called tumors of the brain. Steatomatous and fatty tumors are likewise described, but they appear to be more un- common. V. Tubercular disease. Of this very frequent appearance several examples have already been given. It occurs in masses, varying in size from the smallest size to that of an egg; and . these may be either embedded in the substance of the brain, or attached to the membranes. In their earlier stages, they present to us a whitish-coloured cheesy matter, generally en- closed in a cyst; but, in their more advanced forms, we ge- nerally find them presenting a greater or less degree of un- healthy scrofulous suppuration. 262 ORGANIC DISEASES OF THE BRAIN. VI. Induration of the cerebral substance. Several examples of this important affection have been already referred to under the first part of these essays. I have there stated the grounds for believing, that it is the result of a slow inflammatory ac- tion ; that it may continue for a very considerable time in a state of simple chronic inflammation, and then pass gradually into a state of induration : and, it is probable, that there is in some cases formed around the diseased portion, a sac of coa- gulable lymph, giving it the appearance of a new formation embedded in the substance of the brain. In the state of sim- ple induration, this disease may continue for a long time, pro- ducing urgent symptoms, and may at length be fatal by pass- ing into suppuration, or without having suppurated. VII. Ossifications. Under this head are to be included both osseous projections from the inner surface of the cranium, and internal ossifications, which are commonly found in the dura mater, most commonly in the falx. They generally ap- pear to be formed of thin laminae of bone in the substance of the membrane, and many cases of them are on record which did not appear to have produced any symptoms in the brain. In other cases, however, they seem to produce urgent symp- toms, especially when they are in the form of sharp spiculae, or have acute angles which are so situated as to irritate the brain or its membranes. In a case of this kind by Saviard, there was in the broadest part of the falx a small triangular piece of bone with very sharp angles; and, where the dura mater came in contact with these angles, it was livid and dis- charged pus. In another by La Motte, which was connected with epilepsy, the bony spiculae were directed against the pia mater; and in one by Van Swieten, there was an irregular piece of bone an inch long, and half an inch broad, in the sub- stance of the cerebellum. VIII. Hydatids. This name has been applied to several affections of the brain, some of which do not appear to be really hydatids. Of this kind are the vesicles which are often met with in the choroid plexus; they seem to be merely the loose celular texture of that organ, elevated into vesicles by a watery effusion; and in a case by Dr. Baillie, they could be injected from the veins. Real hydatids, however, do occur in the brain, as in a case which will be quoted from Zeder, in which there were numerous hydatids, one of them the size of an egg, and containing three small hydatids within it. Cysts containing a watery fluid likewise occur in various parts of the ORGANIC DISEASES OF THE BRAIN. 263 brain ; but it is doubtful whether they are to be considered as hydatids. A woman, mentioned by Bonetus, after a blow on the back of the head, had headach for a year with constant vertigo, and then died apoplectic. In the substance of the left hemisphere, there was a cyst the size of an egg, which contained a clear fluid. In a girl mentioned by the same wri- ter, who died, on the 12th day, of a febrile disease, which end- ed in coma, there was found, on separating the two hemis- pheres, a cyst which burst on a slight touch, and discharged limpid fluid to eight or nine ounces. Bonetus mentions other cysts of a still larger size, one especially attached to the nates and the infundibulum, which burst on taking it out, and dis- charged fluid to the amount of two pounds. The patient had complained of fixed pain in the vertex for four months. I was long inclined to doubt the accuracy of these accounts, and to suppose that, in such cases, the fluid had really been contain- ed in .the ventricles, until I received, through my friend Dr. Frampton, the remarkable case by Mr. Headington, to be af- terwards described, in which a cyst was found in the left ven- tricle containing sixteen ounces of fluid. The affections now briefly described, seem to include the principal modifications of the organic diseases of the brain. Others, however, are met with which do not properly belong to any of these classes, such as the stony tumor in a case to be quoted from Schenkius, the bloody tumor of Rochoux, and the real fungus haematodes of the brain, of which there are some examples on record. Fungous protrusion of the cere- bral substance itself, such as occurs after the operation of the trephine, is occasionally met without any such cause. A man, mentioned by Dr. Donald Monro, had a pulsating tumor 'over the left eyebrow, pressure on which produced headach and giddiness. It increased in size, and after seven months he died lethargic. On inspection the tumor was found to arise from the anterior part of the left hemisphere of the brain,' and to have made its way through the frontal bone. It was the size of a China orange; in its structure it resembled the me- dullary substance of the brain; and it appeared to be covered by the dura mater.* When we endeavour to trace the leading symptoms connected with these various states of disease, we do not find any uni- * Trans. Col. Phy. vol. i. 264 ORGANIC DISEASES OF THE BRAIN. formity, by which particular symptoms can be distinctly refer- red to the various forms of the morbid affections; we can therefore attempt only a very general outline of the principal modifications of the symptoms, which are connected with or- ganic disease of the brain. They appear to be chiefly refera- ble to the following heads. I. The first class is distinguished by long-continued and severe headach, without any other remarkable symptom. The pain varies very much both in its seat and in its severity; and one very remarkable character of the affection is, that the pain sometimes occurs in regular paroxysms, leaving intervals of comparative or complete relief. Some remarkable examples have already been given of this in Cases LXXXIII. and XC, and others will be afterwards referred to. The pain is in some cases acute and lancinating, in others obtuse; and it is some- times referred to a particular spot, as the crown of the head, or the occiput. In many cases it is accompanied by a violent throbbing, and this also may be general, or it may be referred to a particular part of the head, as the occiput or one temple. In the more violent paroxysms the pain is intense, obliging the patient to remain for a considerable time in one position, the slightest motion aggravating it to perfect torture; but the remissions from this severe suffering are often so remarkable as to lead a superficial observer into the belief that it is merely periodical headach, or headach connected with dyspepsia. This latter supposition is also countenanced by the stomach being frequently much disordered, and by the more violent at- tacks being often accompanied by vomiting. The diagnosis, indeed, is sometimes difficult, but, by attention, it will be found that the duration and violence of the pain must lead to a suspicion that the complaint is something more than common headach, and that, though the stomach is at times disordered, yet that the headach is often most severe when no disorder exists in the stomach that can account for it. The patient generally cannot bear a warm room, the noise of company, or even the exertion of cheerful conversation, without being dis- tressed and his headach increased; and the same effects are produced by wine and bodily exertion. He seeks quietness, coolness, and darkness; and in these respects, the disease differs remarkably from dyspeptic headach, which is common- ly dissipated by exercise and cheerful company. Sometimes the paroxysms are accompanied by vomiting, and sometimes ORGANIC DISEASES OF THE BRAIN. 265 by violent throbbing in the head. If, along with these local symptoms, the face be pale and the pulse feeble, and if much active treatment has been employed without relief, we must suspect the presence of organic disease. The terminations of the cases of this first class are various ; they may be suddenly fatal by convulsion, or more gradually by coma, or by gradual exhaustion without either coma or convulsion. A very fre- quent termination is by the accession of chronic inflammation, terminating by effusion or otherwise. In Case LXXXVII.,I have given an example in which there was a remarkable mass of organic disease attached to the falx, while no symptoms had indicated its existence, until the occurrence of the symp- toms of chronic inflammation a few weeks before death. II. In the second form, after some continuance of fixed headach, the organs of sense became affected, as the sight, the hearing, the taste and smell, and occasionally the intellect. The loss of sight generally takes place gradually, being first obscured, and after some time lost; and very often one eye is thus affected before the other is at all impaired. Double vision also occurs, which either may be permanent or occur at intervals. One remarkable case will be referred to, in which the blindness took place rather suddenly, and, after it had con- tinued for some time, sight was restored under the action of an emetic. It remained distinct for an hour, and then was permanently lost. The intellect is frequently impaired in cases of this class, and sometimes the speech is lost. The morbid appearances present no uniformity ; in two of them there were tumors so situated, as directly to compress the optic nerves ; in another, a large tumor pressed upon the corpora quadrige- mina ; in a third, the disease was situated at the lower part of the anterior lobe; and in an other, in which the right eye only was affected, it was in the substance of the left hemisphere, near the posterior part. In a case by Drelincurtius, the dis- ease was an enlargement of the pineal gland ; and in another, in which there were both blindness and deafness, a large tu- mor was situated between the brain and the cerebellum. III. The third class corresponds with the second in the pain and affections of the senses, with the addition of parox- ysms of convulsion. These may occur with some degree of regularity like epilepsy, or may take place only at particular periods, when the disease seems to be aggravated, and to be * 34 266 ORGANIC DISEASES OF THE BRAIN. combined with some degree of inflammatory action. Some- times the paroxysms have a resemblance to tetanus, and at others to slight apoplectic attacks. A"case of this kind will be referred to, in which there was loss of sight, hearing, smell, and speech, and at last of the power of deglutition. The cases of this class present the same varieties of morbid appearance as the former, and no peculiar character can be traced in them, which enables us to explain the diversities of symptoms in the three classes, except in regard to those cases in which the disease was so situated, as directly to Compress the optic nerves. This seems invariably to produce blindness; but, in other cases it will appear,, that tumors, corresponding in their situation and nearly of similar size, were in some cases accompanied with blindness and convulsion; and in others by blindness without convulsion; and in others by pain alone, without either of these affections. One case which will be referred to was remarkable, from the circum- stance that the • convulsions ceased when the lungs be- came affected, and did not return, the affections of the lungs being fatal. IV. The fourth class is distinguished by convulsion, with- out any affection of the senses, often with very little complaint of pain, and in general without that fixed and constant pain which occurs in the other classes. The convulsion in some cases appears tinder the regular form of epilepsy; in others, in more irregular attacks, occurring repeatedly for a short time, and then ceasing for a considerable interval. Some- times violent paroxysms of headach precede or accompany the convulsions, and, generally, after some time, the memory is impaired. The cases of this class may be fatal in one of the attacks of Convulsion, or by coma of some days continu- ance. The morbid appearances are very various. The most remarkable in the cases to be referred to were, tubercules in the cerebellum, an hydatid in the right hemisphere of the brain, induration of the pons Varolii or of the substance of the brain, and tumors and bony spiculsea in various situations. An im- portant variety of the disease occurs, in which the convulsion is confined to one side of the body. In one case of this kind, there was a tumor on the surface of the opposite hemisphere, and in another a portion of the opposite hemisphere was indurated; the former case was also remarkable from the ORGANIC DISEASES OF THE BRAIN. 267 long continuation of the disease, and from the weakness and diminution of size of the lower extremity of the affected side. V. The fifth class leads our attention to a new set of symp- toms, namely, the paralytic. These may occur in the form of he- miplegia, paraplegia, or paralysis of all the parts below the neck, and in some cases one limb only is affected. The disease is distinguished from the ordinary paralytic cases, by coming on more gradually ; one limb, perhaps, or part of a limb, being first weak, and the weakness extending very gradually, until it amounts to paralysis. In some cases the paralysis is pre- ceded by violent pain in the limb. The speech is generally affected, and in many cases the memory; there may be fixed uneasiness in the head, or headach occurring in paroxysms. In one case, there was blindness of one eye; in another, of both. In one, there occurred convulsion, but not till an ad- vanced period; in another, epilepsy for more than a year. The inspections exhibit tumors or indurations, variously situ- ated ; in the cases of hemiplegia, on the opposite side of the brain; in those of paraplegia, in the cerebellum or tuber an- nulare. It must, however, be confessed, that the cases 6f this class, with paraplegia, are rather unsatisfactory from want of attention to the condition of the spinal cord. In several cases, to be afterwards described, it will be found that though there was disease in the brain, the real cause of the paraplegia appeared to be in the spinal cord ; and, perhaps, it may be considered as a point not yet ascertained, whether paraplegia ever arises from disease confined to the brain. • VI. The sixth class calls our attention to a subject of much interest; a train of symptoms which are referred to the sto- mach, but which really depend upon disease in the brain. In many of the cases of organic disease of the brain, the stomach is affected; but those to which I now allude, are remarkable from the affection in the stomach being the prominent symp- tom. In these there is often, through a considerable part of their progress, very little complaint of the head, or no com- plaint so fixed and urgent as to direct our attention to the brain as the seat of the disease. There is generally, however, some pain or weight in the head, sometimes occurring in pa- roxysms like periodical headach, or in paroxysms accompanied 268 ORGANIC DISEASES OF THE BRAIN. by vomiting, like what is commonly called sick headach. The pain is increased by exertions, external heat, passions of the mind, and stimulating liquors; there is generally variable ap- petite, bad sleep, oppression of the stomach, and frequent vo- miting. The vomiting sometimes occurs in the morning, on first awaking, and sometimes at uncertain intervals, and very suddenly without any previous sickness. There are, in ge- neral, uneasy sensations referred to various organs, by which the nature of the disease may be disguised in its earlier peri- ods ; but, after a certain time, symptoms referable to the head generally begin to appear, such as fits of loss of recollection, convulsive paroxysms, and affections of sight. After this stage of the disease, death may occur suddenly in an attack of convulsion, or it may be preceded by a train of severe suf- fering. In cases of this class we must beware of being mis- led in regard to the nature of the complaint, by observing that the symptoms in the stomach are alleviated by a strict regi- men, or by treatment directed to the stomach itself. If diges- tion be impeded, from whatever cause, the uneasy symptoms may in this manner be alleviated; but no inference can be drawn from this fact, in regard to the cause of the derange- ment. In the earlier periods of this affection, the diagnosis is indeed often very difficult. There is generally more perma- nent and fixed uneasiness in the head, than we should expect to find m a dyspeptic case, and the uneasiness is increased by causes which would probably be beneficial to a dyspeptic headach, such as activity and cheerful company. The promi- nent morbid appearances in cases of this class seem to be in the cerebellum. VII. The seventh class is distinguished chiefly by slight and transient affections of an apoplectic character, of which I have formerly given some remarkable examples. In some cases, it consists chiefly of an habitual giddiness, which makes the patient afraid to walk alone; in others, there are sudden attacks of loss of all muscular power without loss of recollec- tion, which are soon recovered from. Sometimes there are attacks of perfect coma, which may occur at regular or at ir- regular intervals; the patient having, in some cases, such warning of their approach that he goes to bed before the at- tack. There is usually more or less unsteadiness of the limbs, and generally, but not always, headach. In some cases there ORGANIC DISEASES OF THE BRAIN. 269 are affections of sight, and these may either be permanent or occur in paroxysms ; and in some cases, giddiness and loss of recollection are excited by bodily exertion, and go off on desisting from it. This imperfect outline of a most important class of dis- eases, I shall illustrate by a selection of cases in an Appen- ' dix, partly from my own observation, and partly from other authorities. From these will appear the extreme difficulty of fixing upon any general principles, or of referring the particu- lar character of the symptoms to any thing in the seat or na- ture of the disease. Tumors, for example, will be found under the first class, unaccompanied by any remarkable symp- toms ; while, under the other classes, tumors in the same situ- ation, and of no larger size, were accompanied by blindness, convulsions or paralysis. It does not appear that these di- versities depend either upon the size of the tumors, or, as far as we know at present, upon their particular structure. But these points remain to be investigated ; particularly what di- versity of symptoms is connected with the nature of the tumors, and especially with their characters, as being tumors distinct from the cerebral mass, or as being indurations of the sub- stance of the brain itself. In regard to the treatment of this class of diseases, there is little to be said. I am persuaded, however, that we ought not to consider them all as hopeless. Many of them have certainly their origin in inflammatory action, and, by the proper treat- ment, we have every reason to suppose that their progress may at least be impeded, and the life of the patient prolonged, as well as rendered more comfortable. The treatment will consist in keeping the system extremely low by evacua- tions and spare diet, cold applications to the head, issues or setons in the neck, and avoiding all causes of excite- ment. I conclude this part of the subject with the following important case, which I received from my friend the late Dr. Kellie of Leith. It illustrates, in a very striking man- ner, the nature of the symptoms which may exist with most extensive and remarkable organic disease of the brain. Case CXL.—A medical gentleman aged 56, of a culti- vated mind and temperate habits, had been for some time 270 ORGANIC DISEASES OF THE BRAIN. liable to various ailments, which his medical friends consi- dered as in a great measure hypochondriacal. The most de- fined complaints were occasional uneasiness in the site of the frontal sinus, and a very peculiar feeling of numbness in the point of the thumb. But his general health appeared good, and he was able to enter into all the usual enjoyments of life, having retired from practice, till he was one day seized, while walking, with sudden sickness and faintness. These were followed by some headach, and an obvious difficulty of articulation, or rather a difficulty in finding the expression which he wished to make use of. He was now treated by bleeding and the other usual means ; but this peculiar loss of the recollection of words continued and gradually increased, so that he had greater and greater difficulty in recollecting the words which he meant to employ, but he had no diffi- culty in pronouncing them. His understanding, at this time, was quite entire; his pulse varying from 80 to 112. He was nearly confined to the house, but out of bed during the day; and all the usual remedies were employed in the most assiduous manner. After he had gone on in this way for several weeks, he began to have slight distortion of the mouth, and complained of numbness of the right arm, and soon after of weakness of the right leg. These symptoms gradually in- creased to perfect hemiplegia; and about this time, also, he entirely lost his speech. He was now confined to bed, but without coma. He had the perfect use of his sight and hear- *»* ing, and, as far as could be judged, his understanding was entire. He died with symptoms of bronchitis in the ninth week from the first attack. Inspection.—The left hemisphere of the brain was found to be diseased throughout in a very singular manner. Some parts of the mass were indurated, others softened ; and it pre- sented a variety of colours, chiefly a rose colour, grey, and yel- low ; and the more diseased portions were highly vascular. In some places there were distinct insulated masses, enclosed in vascular cysts; these were generally indurated, but some were softened, and they were of a rose or flesh-colour passing into gray. The change from those parts which retained a natural appearance to these degenerated portions was abrupt, and marked by a rose-coloured line. These rose-coloured por- tions were chiefly in the parts nearest the surface; in the central parts this passed into the yellow or the grey, and ma- ny portions were in a state of ramollissement. The whole ORGANIC DISEASES OF THE BRAIN. 271 left hemisphere, in fact, presented little else than a mass of concentric indurations and softenings of the various colours which have been mentioned. On the upper part of the hemi- sphere, the disease did not extend entirely to the surface of the convolutions; but at the base of the anterior and mid- dle lobes it extended to the surface, and at one place there was a well-defined spot of superficial ulceration the size of a split pea. PART IV. OF THE DISEASES OF THE SPINAL CORD AND ITS MEMBRANES. In its structure, the spinal cord is very analagous to the brain, except that it is more dense in its consistence. The membranes of the cord are usually divided into three, the dura- mater, arachnoid, and pia mater ; but as that which has been termed the arachnoid seems rather to be a kind of loose cel- lular texture, scarcely deserving a distinct name, it will an- swer every practical purpose to consider the membranes as two. I. The dura mater of the cord does not differ in structure from that of the brain, except in varying considerably in thick- ness at different parts. The principal facts to be kept in mind in a practical point of view are, that it adheres very slightly to the canal of the vertebrae by a very loose cellular texture, and that it adheres very intimately to the margin of the fora- men magnum. In this manner a cavity is produced betwixt the membrane and the canal of the spine, which may be the seat of effusion, and which has no communication with the cavity of the cranium ; on the other hand, the space betwixt the dura mater and the pia-mater, or the immediate covering of the cord, communicates freely with the cavity of the cra- nium, so that a fluid may pass easily from the one to the other, according to the position of the body. II. The pia mater, or proper covering of the cord, is a mem- brane of a loose or cellular texture. It seems to be continu- ous from the pia mater of the brain, is closely attached to the DISEASES OF THE SPINAL CORD. 273 body of the cord, and furnishes a covering to the nerves which issue from it. III. The substance of the cord is firmer than that of the brain, but in other respects analogous to it; being distin- guished into cortical and medullary matter. It is divided into four columns, the two anterior of which take their ori- gin from the crura cerebri, and the two posterior from the" crura cerebelli. The spinal nerves arise by two distinct roots from one of the anterior, and one of the posterior of these columns ; and recent investigations have rendered it probable, that a diversity of function is concerned in the dou- ble origin, that is, that the posterior columns give origin to the nerves of sensation, and the anterior to the nerves of mo- tion. A canal has been described in the substance of the cord, which is said to be a seat of serous effusion, and to com- municate with the fourth ventricle. On the authority of Por- tal, Senac, Rachetti, and others, we cannot doubt that such a canal has been observed, but it seems very doubtful whether it exists in the healthy state of the parts. In Portal's case, it extended as far as the fourth dorsal vertebrae, and would have admitted a common quill. It was full of serous fluid, by which the ventricles of the brain were likewise distended. By the ancients, much importance was attached to the spi- nal cord in convulsive and paralytic affections, but their spe- culations seem to have been in a great measure conjectural. A correct pathology of the cord appears to be of very modern date, and perhaps may still be considered as being in a very imperfect condition. In attempting a general outline of it, I shall satisfy myself with a simple record of the best authen- ticated facts, which may be arranged under the following heads : I. Acute inflammation of the membranes, or meningitis of the cord. II. Inflammation of the body of the cord, terminating by ra- mollissement or suppuration. III. Serous effusion in the spinal canal. IV. Extravasation of blood in the spinal canal, or spinal apoplexy. V. Fungoid disease and thickening of the membranes. VI. Induration of the cord. VII. Compression of the cord by new formations within 35 274 MENINGITIS OF THE CORD. the canal, as tubercles, albuminous depositions, hydatids, and ossification of the membranes. VIII. Destruction of a portion of the cord. IX. Concussion of the spinal cord. X. Certain affections of the bones of the spine- SECTION I. MENINGITIS OF THE CORD. Of this remarkable affection, I am enabled'to give the two following examples, the second of which I received from the late Dr. Duncan.* The other I did not see during the life of the patient, but I was present at the examination of the body. I shall merely relate the cases, without founding upon them any general conclusions in regard to the characters of the dis- ease. Case CXLI.—A gentleman aged 26, had been for several years liable to suppuration of the left ear. It usually dis- charged at all times a little matter, but the attacks of pain were followed by more copious discharges ;—the pain on these occasions extending over the left side of his head, and often continuing for a week with much severity. In the first week of April, 1817, he was confined from his usual employments by headach, which affected both the forehead and the occi- put ; he lay in bed only part of the day; his appetite was bad, and his sleep disturbed ; but there was little or no fre- quency of pulse, and for a week the complaint excited little attention. About the end of the week, he complained of pain extending along the neck, and in the beginning of the second week the pain in the head nearly ceased, but the pain in the neck became more severe, and extended farther downwards along the spine. It continued for several days to extend far- ther and farther down, until at last it fixed with intense seve- rity at the lower part of the spine, and extended from thence round the body, towards the spinous processes of the ilia.— From this time he never complained of his head, and seldom of the upper parts of the spine ; but he became affected with MENINGITIS OF THE CORD. 275 great uneasiness over the whole abdomen, and great pain and difficulty in passing his urine. From the violence of these com- plaints, his sufferings about the 15th became extreme ; he could not lie in bed for five minutes at a time, but was generally walk- ing about the house in a state of extreme agitation, grasping the lower part of his back with both his hands, and knashing his teeth from the intensity of pain ; he had no interval of ease, and was sometimes incoherent and unmanageable.— On the 16th, he went to the warm bath, walking down three stairs, and into an adjoining street, with little assist- ance. After his return from the bath he thought himself somewhat relieved, but the pain soon returned with its former severity, accompanied by great pain in the belly, severe dy- suria, confusion of thought, and some difficulty of articulation. The pulse was about 100, and the bowels were easily kept open by the ordinary medicines. On the 17th, the symptoms were unabated ; his speech was considerably affected ; there were convulsive twitches of his face, and difficulty of swal- lowing ; some squinting also was observed, but it was not permanent; the pulse was from 120 to 130. At night he be- came easier after a bleeding from the arm, and lay in bed for some time. After a short time, however, he got up again, and continued till three o'clock in the morning, sitting up or walking about his house, delirious and unmanageable. About three o'clock, while sitting in a chair, he suddenly threw his head backwards with great violence, and immediately fell into a state of coma, in which he continued for two hours, and then died. No paralytic affection had been observed in any period of the disease, except the slight affection of his speech, no dif- ficulty of breathing, no vomiting, and no convulsion except the twitches of the face on the 17th. The pulse had varied from 90 to 130, and was reported to have been generally small and irregular. The bowels were easily kept open, but the pain in the back was much increased by going to stool. Two days before his death he had several attacks of shivering.— During his illness, much purulent matter had been discharg- ed from the left ear, and an inflamed tumor had formed be- hind it. Inspection.—After the most careful examination, every part of the brain was found to be in the most healthy state. On takino- out the brain, some gelatinous deposition was found underthe medulla oblongata, and purulent matter appeared in 276 MENINGITIS OF THE CORD. considerable quantity, flowing from the spinal canal. The spine being entirely laid open, the cord was found with a coat- ing of purulent matter, which lay betwixt it and its membranes. The matter was most abundant at three places; at the upper part near the foramen magnum, about the middle of the dor- sal region, and at the top of the sacrum ; but it was also dis- tributed over the other parts with much uniformity. The sub- stance of the cord was very soft, and in some places much divided into filaments. All the other viscera were healthy. Case CXLII.—A woman aged 22, had been for more than three weeks affected with pains of a rheumatic character, ex- tending over every part of the body, when, on the 11th of April, 1820, she was received into the clinical ward, under the care of Dr. Duncan. She then complained of pain in the back of the neck and loins, and at the top of the right scapu- la ; also of an acute »pain in the right hypogastric region, in- creased by pressure and by inspiration. The head was con- siderably retracted, and could not be bent forward; the spine was bent backwards, and the muscles of the back felt contract- ed and rigid. She had alternate rigors and flushes of heat, great restlessness; pulse 148 and full; respiration 44, with some cough ; tongue foul; bowels confined. She was treat- ed by large bleeding, purging, warm bath, &c. On the 12th there was little change. On the 13th, she had difficulty of swallowing, and great restlessness; the spine was curved backwards as before, and the bowels were obstinate, pulse 144. On the 14th, after free purging was produced, she seem- ed somewhat relieved, and could bring her head a little for- ward ; but she said the pain was unabated. It was now chiefly referred to the right shoulder, and the upper part of the chest, sometimes shooting into the right axilla. She had also pain in the lower part of the belly, and the abdomen felt dis- tended and tense. She had less difficulty of swallowing, and was inclined to sleep, but during sleep there was much sub- sultus ; pulse 148 and small. On the 15th, the head was less retracted, and there was more power of moving it. The pains were abated, except in the abdomen; there was much sub- sultus and tremor; pulse 140; bowels open; tongue foul. She was much inclined to sleep, but quite distinct when roused. At night she was put into the warm bath, and expired in the bath. Immediately after death the muscles of the neck be- came entirely relaxed. MENINGITIS OF THE CORD. 277 Inspection.—There was some fluid in the ventricles of the brain ; and, on the posterior edge of the right lobe of the cere- bellum, there was a thread of coagulable lymph. The cervi- cal portion of the spinal cord was healthy; the dorsal and lumbar portions were covered by a uniform thin coating of co- agulable lymph of a greenish-yellow colour, and soft consist- ence. It was chiefly on the posterior part, betwixt the cord and its membranes, and the membranes were remarkably vas- cular. Several cases have been described by Duchatelet and Mar- tinet, of inflammation of the membranes of the cord terminat- ing by puriform deposition, but they were in general compli- cated with a similar disease in the membranes of the brain. The prominent symptoms, referable to the spinal cord, were, pain extending along the spine, and tetanic contraction of the muscles of the back and neck, in some of them amounting to perfect opisthotonos. In one there was rigidity of the mus- cles of the left arm, with a convulsive twitching of the thumb and fingers of both hands ; in another, there was a remarkable slowness of breathing, which was not above five in a minute. Ollivier, in his second edition, has described several inter- esting cases, which present the same general characters. The prominent symptom was, pain referred to some part of the spine, increased by motion, and sometimes little complained of except upon motion; it in general extended along some of the limbs, and was accompanied by muscular rigidity or tetanic spasms. Paralysis occurred in one case, but this seemed to depend upon a degree of ramollissement of the body of the cord. One of his cases was remarkable from the remissions of the symptoms in the first stage. There was an acute pain referred to the neck, which came on with intense severity at ten o'clock at night, and ceased at three in the morning. Af- ter seventeen days this ceased, and was succeeded by pain in the loins, which afterwards extended along the back and into the inferior extremities ; and was then accompanied by mus- cular rigidity, and tetanic spasms of the legs, back, and neck. The patient at last died comatose ; and the case seems to have gone on about five weeks. There was extensive deposition of pus and false membrane between the membranes of the cord at various places, especially in the lumbar region, where the matter had found an outlet betwixt two of the vertebrae, and had spread under the muscles. In another case, the pymp- 278 MENINGITIS OF THE CORD. toms were, at first, more obscure. There was an expression of suffering with retention of urine, but no defined complaint, except that the patient screamed when his lower extremities were moved, and they became paralyzed without loss of feel- ing. There were afterwards rigidity and partial paralysis of the arms, rigidity of the trunk, and retraction of the head; and he died in ten days. Between the membranes of the cord there was an extensive deposition of false membrane and floc- culent matter, in some places four or five lines in thickness. It was most abundant on the posterior surface of the cord, and towards its lower extremity; and there was some soften- ing of the substance of the cord.* To these examples of this remarkable disease, I shall only add a case mentioned by Andral. A woman aged 28, after sudden cessation of the menstrual discharge, induced by men- tal agitation, had fever, hysterical symptoms and vomiting ; about the fifth day she had retraction of the head, with severe pain extending along the whole course of the spine; it was not affected by pressure, but was increased to extreme agony by the least motion. She had afterwards difficult breathing and tetanic symptoms, followed by delirium and insensibility, and she died on the tenth day. On inspection there was found extensive deposition of purulent and flocculent matter, along the whole course of the spinal cord, which seemed to be con- tained chiefly in the cellular texture of the arachnoid of the cord. The membranes of the brain were deeply injected ; there was membranous deposition on some parts, especially on the right side, also on the tentorium and below the cere- bellum,—and there was extensive effusion of milky fluid in the ventricles. Inflammation of the parts surrounding the spinal cord may also be excited by external injuries, without any affection of the bones of the spine. A wagoner, mentioned by Sir Charles Bell, sitting upon the shafts of his cart, was thrown off by a sudden jerk, and pitched upon the back of his neck and shoulders. He was carried to the Middlesex Hospital, where he lay for a week, without complaining of any thing except stiffness of the back part of the neck ; he could move all his limbs with freedom. On the 8th day after his admis- sion, he was seized with general convulsions and locked jaw. After a few hours, he was affected with a singular convulsive * Ollivier, Traitd de la Moelle Epiniere et ses Maladies. Tome ii. 16 edit. MENINGITIS OF THE CORD. 279 motion of the jaw, which continued in a state of violent and incessant motion for about five minutes. This was followed by maniacal delirium. He then sunk into a state resembling typhus fever, and, after four days, was found to be paralytic in his lower extremities. '• He lived a week after this, but continued sinking, and still retained about him much of the character of typhus. The day before his death, he was per- fectly sensible, and had recovered sensation in his legs." On dissection, a great quantity of purulent matter was found with- in the spinal canal, which had dropped down to the lower part of it. It appeared to have been formed about the last cervi- cal and first dorsal vertebrae, and at that place the interverte- bral cartilage was destroyed, so that the pus had escaped out- wards among the muscles. In another case related by Sir Charles Bell, in which the last dorsal vertebra was - fractured, purulent matter was found betwixt the spinal cord and its membranes. In this case there was no paralysis. The lead- ing symptoms were fever, restlessness, vomiting, and high de- lirium ; death took place from sudden sinking.* To this place, perhaps, should be referred some notice of the appearance of increased vascularity of the cord or its mem- branes, and turgidity of vessels about the origin of the nerves. It constitutes the plethora spinalis of continential writers ; and much importance has been attached to it as the cause of dis- ease in many of the principal functions of the body. By ex- citing irritation at the origin of the various spinal nerves, it has been considered as the source of many obscure affections of the thorax and abdomen ; of tremor, convulsions, paralytic affections, chorea, epilepsy, and tetanus. It has also been re- garded as the seat of many of those painful affections of the back and the loins, which take place in connexion with hae- morrhoids, menstruation, abortion, and continued fever. These writers have speculated much on the changes which take place in the thoracic and abdominal viscera, so as to throw the blood with undue impulse upon the vessels of the spinal cord. Such determinations they suppose to take place from violent colics, suppressed menstruation, diseases of the liver, and continued fever.f It must, however, be confessed, that * Quarterly Reports of Cases of Surgery, part 2. + See Frank, Oratio de Vertebralis Columnse in morbis dignitate, Brera deJla Ra- chialgite, and Ludwig de Dolore ad Spina* Dorsi. 4 280 MENINGITIS OF THE CORD. the morbid appearances, which are referable.to the head of spinal plethora, are extremely ambiguous ; and there is little doubt that they are very much influenced by the position of the body after death ; but it is due to the speculations of wri- ters of high eminence, to give an example of the affections which they refer to this class. (1.) A man who died of peripneumony, had been affected in the course of his illness with numbness and loss of feeling in the lower extremities. On dissection, the arteries of that part of the spinal cord, which is included in the dorsal verte- brae, were found turgid with blood, as if they had been highly injected.* Portal refers to several other cases, which he ex- plains upon the same principle, and in which convulsive and paralytic affections of the extremities occurred in various in- flammatory diseases. (2.) An infant was attacked during dentition with convul- sions, which degenerated into epileptic fits. When he was five years and a half old, he had four or five fits every day, and became paralytic ; he died at six years and a half. The spinal sheath appeared as if injected, and the mudullary sub- stance was softened and of yellowish colour about the 6th and 12th dorsal vertebrae.f (3.) A young man, aged twenty-one, was affected with fe- ver and high delirium. When the delirium subsided, he had convulsive motions of the superior extremities, and soon after died comatose. On dissection, the vessels of the pia mater of the spinal cord, at its upper and posterior part, were found distended with blood, as if they had been highly injected. This was especially remarkable about the origin of some of the spinal nerves. There was a similar appearance on the pia mater of the brain, and some effusion on its surface.^ SECTION II. INFLAMMATION OF THE SUBSTANCE OF THE SPINAL CORD. In referring to inflammation of the substance of the cord, the appearances to be described under this section, I am guided by the analogy of the corresponding affections of the brain. * Portal, Cours d'Anatomie Medicale, tom. iii. page 219. t Esquirol Bulletin de la Faculty de Medecin*. X Morgagni, Ep. %, INFLAMMATION OF THE SPINAL CORD. 281 I allude more particularly to the ramollissement, which seems to be one of the most common morbid appearances in the acute affections of the spinal cord, and which, in reference to the brain, I think has been distinctly traced to be a result of in- flammation. I again leave this doctrine, however, to the judg- ment of the reader, and shall make no farther use of it here, than as a ground of arrangement. This important subject has not yet been investigated with that attention which it merits; but there is reason to believe, that inflammation of the substance of the cord, like the corresponding affection of the brain, may terminate fatally in four different forms : I. In the inflammatory stage. II. By ramollissement. III. By undefined suppuration. IV. By abscess. §1.—Inflammation of the substance of the cord fa- tal IN THE INFLAMMATORY STAGE WITH INCIPIENT RA- MOLLISSEMENT. This part of the subject is obscure, and the termination of the disease in the inflammatory stage may perhaps be con- sidered as not ascertained. It may, therefore, be doubted whether the following case can properly be referred to this head;—it is the one most nearly allied to it, that I find on record. A woman had long been subject to a convulsive affection in the left lower extremity, immediately before the appearances of the menses ; this occurred at every period; when the dis- charge took place freely, it ceased. After the cessation of the menses, which happened at the age of 40, this extremity became paralytic. After some time she was affected with convulsions of the left arm, and soon after died comatose. On dissection, the membranes of the spinal cord were found in a state of inflammation at some of the last dorsal vertebrae. The cord itself was very red and softened on the right side; on the left it was sound through its whole extent.* Lieutaud refers to a case described by Laelius a Fonte, in which death happened on the 14th day of continued fever, after paraplegia and suppression of urine ; " in conspectum venit ren sinister, * Portal, Cours d'Anatomie Medical*, tome iv. page 116. 36 282 RAMOLLISSEMENT OF THE CORD. inflammatus et syderatus; laesa etiam erat medulla spinalis in eodem latere." § II.—Ramollissement of the cord. This remarkable affection will be illustrated by the follow- ing important cases. In the first it was complicated with ex- tensive inflammation of the membranes; the second shows the disease confined to the body of the cord; and the third is chiefly remarkable from its resemblance in the symptoms to an affection of the brain. The fourth shows the affection arising from an injury; and the fifth affords a very interesting example of the disease in a chronic form. Case CXLIII.—A gentleman aged 18, of an unhealthy constitution, had suffered for several years from ulcers in va- rious parts of his body, accompanied by exfoliation of bone, especially from the leg, thigh, and sacrum. For several months before the fatal attack, he had a sore on his head with caries of the bone beneath, to the extent of a shilling or up- wards. But he was in good general health, and was pursuing his studies at the University of Edinburgh, when, on the 24th September, 1823, he consulted my friend Dr. Hunter, on ac- count of sore throat with slight fever, which passed off in two days; and, on the three following days, he was going about in his usual health. On the 30th, he was again con- fined to the house, and complained of pain in his loins with- out fever. On the 2d of October, this pain had increased ; it was chiefly seated among the lower dorsal vertebrae, and ex- tended downwards in the course of the ureters, with frequent desire to pass urine. On the 3d, the urinary symptoms were gone, the pain was diminished in violence, and it was lower down, being now chiefly referred to the sacrum. On the 4th, he continued in the same state; he was entirely free from fe- ver ; the pain in the back was by no means severe, but as it was not removed, a blister was applied to it. (5th.) The pain of the back was removed, but he com- plained of pain of the belly, especially about the pubis ; there was some dysuria, and a feeling of numbness on the inner side of both thighs. At night there was retention of urine requiring the catheter. (6th.) The numbness of the thighs was increased, with RAMOLLISSEMENT OF THE CORD. 283 acute darting pains occasionally shooting along them, and complete retention of urine. (7th.) Perfect paraplegia of both thighs and legs without loss of feeling; retention of urine, and involuntary stools. The most judicious treatment had been employed without any benefit. (8th.) I saw him for the first time along with Dr. Hunter. There was now perfect paraplegia and complete retention of Urine ; pulse about 90 and soft. There was some pain, which was referred to the lower part of the dorsal region ; there was no other symptom. Cupping on the back was employed, followed by another large blister, &c. (9th, 10th, and 11th.) There was no change, except that the pulse was becoming a little frequent. His mind was en- tire. Some pain of the back was at times mentioned, but it was not severe, and he made no other complaint. Perfect f>alsy of the limbs continued, and the numbness was extend- ng upwards upon the abdomen. (12th.) The numbness was extending upon the thorax; there was very little complaint of the back, but acute darting pains were complained of extending along both arms. The sore on the head being examined, and the opening enlarged, the bone was found carious, and some matter was discharged from it by a very small opening. In consequence of this ap- pearance, a perforation was made by a small head of a tre- phine, but no disease was found beneath the bone. In the evening, his pulse having become more frequent, farther bleed- ing was employed with relief. (13th.) No change; his mind was quite entire, and he made no complaint of any thing; stools involuntary. (14th.) The urine came off without the catheter, on raising him up into an erect posture. Pulse frequent and feeble; strength sinking. He died in the night, having continued quite sensible until about six hours before his death. There never had been the least attempt at motion of the lower ex- tremities, but the sensibility remained. Inspection.—In the brain all was quite sound, except some old thickening of the dura mater in the neighborhood of the diseased bone. The bone was carious and very thin to the extent of a half-crown piece ; around this portion it was thick- ened, especially on one side, where it was fully double the natural thickness. There was no effusion in the head, and no appearance of any recent disease. 284 RAMOLLISSEMENT OF THE CORD. In opening the spinal canal some purulent mater flowed out during the sawing, from about the middle of the dorsal re- gion ; and one of the vertebrae at that place was found conside- rably carious. The canal being opened, there was found most extensive deposition of flocculent matter, of a purulent appearance, on the outside of the membranes of the cord; it was most abundant for some inches about the lower part of the dorsal region, but likewise extended upwards to the fourth cervical vertebrae. The dura mater of the cord being laid open, bloody sanious fluid was discharged from beneath it; and the pia mater was found highly vascular. The substance of the cord was found most extensively destroyed in its struc- ture along nearly the whole extent of the dorsal portion. The anterior columns of this part were completely disorganized and broken down into a soft diffluent pulp; on the posterior part, the cord was more entire. When the whole cord was taken out and suspended, it hung together by the posterior columns of the dorsal portion, while the anterior part of it fell off entirely in a soft diffluent state. The parts above and be- low the diseased portion were quite firm and healthy. Case CXLIV.—A man aged 56, in the last week of March, 1823, was much exposed to cold in travelling on the outside of a coach, after which he was seized with pain of the right arm and leg, most severe about the shoulder, but affecting the whole side; and there was also considerable headach. He soon perceived some loss of power of the affected limbs, which began at the upper part of the arm, and extended downwards so gradually, that he was able to write distinctly, after he had lost the power of raising the arm or bending the elbow. The leg then became affected in the same gradual manner, and after about ten or twelve days from the com- mencement of the disease, the whole leg and arm had become completely paralytic. Some pain continued in the parts, and was sometimes severe, especially in the leg. About this time he was first seen by Dr. Moncrieff, who found the pulse 96, and rather sharp. He was quite sensible and still complained of some headach, and of pain extending from the shoulder along the affected arm and leg. Repeated bloodletting, blis- tering, purgatives, &c, were employed, and the headach was removed. The other symptoms continued as before ; the right leg and arm were completely paralytic, and sometimes very painful; pulse 84, and rather weak; his mind quite entire. RAMOLLISSEMENT OF THE CORD. 285 He continued in this state till about the 26th of April, when the left arm became paralytic rather suddenly; it did not how- ever become so completely motionless as the limbs of the right side, and the left leg was not at all affected. The pulse was now feeble, and his general appearance expressive of exhaus- tion. I saw him first about this time. There was slight de- lirium, which however passed off again; and he continued quite sensible and even cheerful, without any pain, except occasionally in the right leg, till the 7th of May, when he became again delirious; the pulse 120, and weak. On the 8th, he lay in a state of stupor, muttering incoherently, but answering questions distinctly when he was roused. He died on the morning of the 9th, having lost his speech a few hours before death. For the last eight or ten days there had been extensive gangrene on the sacrum. Inspection.—Every part of the brain was found in the most healthy state. Much bloody fluid was discharged from the spinal canal into the cavity of the cranium before the spine was laid open. On laying open the spinal canal, the cord was found in a state of complete ramollissement, from the second to the last cervical vertebra; the parts above and below were quite healthy. The following case shows the disease running its course with much greater rapidity, and with a different train of symptoms. Case CXLV.—A boy aged 7, had been indisposed from the 18th to the 20th of May, 1823, but so as to attract little notice. There had been some headach and slight feverish- ness, for which he took purgative medicine, and on the morn- ing of the 22d he seemed almost well. About two o'clock in the afternoon of that day, he was seized with severe and ge- neral convulsions. I saw him soon after this, and found him confused, incoherent, and partially comatose; the pulse 60 and weak; face pale; the bowels were slow, and some worms had been passed. The usual remedies were employed with little effect. (23d.) In the morning he was partially comatose, the eye fixed and insensible. In the course of the day he be- came less comatose, but incoherent, with much talking and screaming; complained of headach, and was impatient of light. In the evening there was slight appearance of squint- 286 RAMOLLISSEMENT OF THE CORD. ing, and in the night some convulsions ; pulse very variable, being sometimes rapid and sometimes slow; the bowels were very obstinate, but yielded to repeated doses of croton oil. (24th.) Seemed much better,—eye natural, face pale, pulse 120, bowels kept open by the croton oil. He was quite sen- sible, and said there was still some headach, but did not ap- pear to suffer; he continued in this favourable state until ear- ly in the morning of the 25th, when the convulsions returned with much severity, after which he sunk into a low, oppressed state, and died early in the afternoon. Inspection.—There was no effusion, and no appearance of disease in the brain. On removing the brain, a considerable quantity of fluid flowed from the spinal canal; and on laying open the canal there was still a good deal found between the cord and the external membrane. The cord was healthy at the cervical portion, but in the upper part of the dorsal region it was remarkably softened and broken down. This appearance extended for several inches, but varied in degree. At one place a complete separation took place in attempting to raise the cord, the part falling down into a soft diffluent pulp through its whole diameter. From the middle of the dorsal portion it was quite firm and healthy. The inner membrane of the cord was dark-coloured, highly vascular, and showed evident marks of inflammation, at the part corresponding with the softened portion of the cord. The following case (for which I am indebted to Dr. Hun- ter) shows this affection arising from an external injury, with- out any affection of the bones of the spine. Case CXLVI.—A man aged 36, in August, 1827, was thrown from the top of a wagon, a height of about ten feet. he alighted upon a pile of small stones, in such a manner, that the shock, on first coming in contact with the top of the pile, was received on his back, between the shoulders. He attempted immediately to get up, but fell instantly from com- plete loss of power of the lower extremities ; and very soon after, he had involuntary discharge of urine and faeces. He was conveyed home in this state, but little appears to have been done for him except the application of sinapisms; and it was about a month after the accident, when he was received into the Infirmary of Edinburgh under the care of Dr. Hunter. He was then considerably emaciated, and there was complete RAMOLLISSEMENT OF THE CORD. 287 loss of motion of the lower extremities, without loss of feel- ing, and all the muscles of the affected parts were in a re- markable state of flaccidity. He complained of deep-seated pain on pressure of the region of the third, fourth, and fifth dorsal vertebrae. He had liquid stools, which were discharged involuntarily. His urine was at first discharged involuntarily, mixed with much viscid mucus; afterwards it became ob- structed, apparently from the viscidity of the mucus impeding the passage,and he then required the catheter. His breathing was very slow, being generally, when he was asleep, about nine in a minute ; and when awake about thirteen. His pulse and other functions were natural; his appetite was moderate, and his digestion good ; his mind was quite entire. On the third day after his admission, he began to complain of pain in the temporal and masseter muscles, with inability to open the jaw; and this rapidly increased to perfect trismus. He then had emprosthotonos, and the usual tetanic symptoms; the abdominal muscles being very tense and hard, and the body considerably bent forward. On the following day more ge- neral spasms took place, affecting the arms and face, and the muscles about the neck and throat, with great difficulty of swallowing. The spasms now assumed the form of opistho- tonos. He died in the night, about forty-eight hours after the first appearance of the trismus. All the usual remedies had been employed in the most active and judicious manner with- out benefit. Inspection.—No injury could be detected in any of the bones of the spine. There was a high degree of vascularity of the pia mater of the cord, especially at the upper part of the dorsal region. There was most extensive ramollissement of the body of the cord, which affected chiefly the anterior columns. These were most remarkably softened throughout almost the whole course of the cord, in many places entirely diffluent, and the softening was traced quite to the upper part of the cord, and affected the corpora pyramidalia. The pos- terior columns were also softened in many* places, though in a much smaller degree, not diffluent like the anterior, but break- ing down under very slight pressure. A remarkable modification of the disease occurs, in which, although it is seated in the upper part of the cord, the symp- toms appear only in the superior extremities and adjoining organs, without any affection of the lower parts of the body. 288 RAMOLLISSEMENT OF THE CORD. A gentleman, mentioned by Ollivier, who was liable to epi- lepsy, complained first of uneasiness in the throat, with diffi- culty of swallowing, accompanied by an acute pain in the nape of the neck, and lower part of the occiput, and speedily followed by fever, difficult breathing and vomiting. He then had numbness of the left hand, which rapidly extended along the arm ; the right was immediately after affected in the same manner, and on the following day they were both paralytic. His legs were not in the least affected, nor the functions of the bladder or the bowels. There was at last increase of dyspnoea with extreme difficulty of swallowing, while nothing could be seen in the throat, and he died on the eighth day, having preserved his intellects to the last. There was exten- sive ramollissement of the upper part of the cord, chiefly seated in the grey matter, which was of a rose-colour, with a highly vascular state of the membranes connected with the part; there was extensive effusion in the spinal canal, and some extravasated blood in the cellular tissue between the vertebrae and the dura mater of the cord. The lungs were dense and loaded with blood, and there was increased vascu- larity of the bronchial membrane. In another case, with ex- tensive ramollissement at the upper part of the cervical por- tion, there was palsy of all the extremities. The only differ- ence in the morbid appearances, betwixt the two cases, seems to have been, that the ramollissement in the former was chiefly seated in the grey matter, while in the latter it extended nearly through the whole thickness of the cord. Ollivier has also described several cases which followed a course similar to Case CXLV., being fatal in about three days, with violent convulsion without paralysis. The disease occurs in a more chronic form, in which it may go on for a considerable time, sometimes for years, before it is fatal. There is generally in these cases some uneasiness in the back, with paralytic symptoms, beginning in a part of a limb, and in a slight degree, and advancing very gradually to confirmed palsy. The lower extremities are most commonly affected, but in some cases the arms only, and in others all the limbs. There is sometimes permanent contraction of the af- fected limbs, and sometimes there are spasmodic affections of them ; and the disease may go on in this manner for years, and at last be fatal by ramollissement. RAMOLLISSEMENT OF THE CORD. 289 This form will be illustrated by the following case, which I saw along with Dr. Alison. Case CXLVIL—A gentleman aged 42, in October, 1827, began to be affected with pain in the lower part of the back, stretching round the abdomen, and frequently shooting into the groins. After a short time this was succeeded by cold- ness and numbness of his feet, which gradually extended up- wards with diminished power of motion, until, after several weeks, it termiqjited in perfect loss of motion of both lower extremities, with retention of urine. There was pain in some parts of the affected limbs, and in others a painful sensation of cold. This perfect loss of power continued five or six weeks, when after a great deal of treatment by cupping, blis- tering, &c, he recovered a slight degree of motion, but no power of the bladder. He then began to be affected with spasms of the muscles of the back and abdomen, with a very uneasy sensation of tightness across the abdomen, and at times across the lower part of the thorax. The spasms oc- casionally assumed the character of opisthotonos, and at one time he had almost incessant hiccup, which continued in a most violent degree for several days. After the employment of various antispasmodics, this subsided under the use of musk. During the course of these symptoms, he frequently com- plained of pain in various parts of the spine, at first in the lower part, and afterwards higher up ; and the feeling of numbness extended gradually upwards, till it reached nearly the upper part of the dorsal region, and was felt in a very considerable degree along the sides of the thorax. - After this he became liable to feverish attacks at night, ter- minating in the morning by very profuse perspiration, but this was strictly confined to the parts which were not palsied, and there never was the smallest moisture on the lower extremi- ties. He had also, in the upper extremities, a frequent feel- ing of intense heat, while the lower continued cold and be- numbed. During this time a considerable, but very imperfect, degree of motion continued in the lower extremities, but the bladder continued entirely paralytic. In April, 1828, he went to the country, and at this time he had such a degree of mo- tion as to walk a little on a smooth garden-walk, leaning on two persons, or supported by crutches. But soon after this he began to complain of pain in the head. It occurred in irregular paroxysms, and was often referred to a small defined 290 RAMOLLISSEMENT OF THE CORD. spot, on various parts, especially behind the ear, and some- times to the tip of the ear. This pain seemed to abate under the use of arsenic ; but soon returned, and became more fixed and permanent, and the palsy of the limbs again increased. After an absence of about two months, he returned to town in the beginning of July. At this time the headach was severe, and the power of the limbs so much impaired, that he was entirely confined to bed. In a few days after his return, the right arnt became paralytic, and his speech considerably impaired. After i a day or two, these symptoms rather subsided, but in the fol- lowing night he became comatose, and died in the afternoon. There never was complete loss of sensation of the affected limbs ; he had only complained of it occasionally at particular spots, and of a general feeling of numbness and coldness. Inspection.—There were some scales of bone attached loosely to the inner surface of the dura mater of the spinal cord. The whole cord was of a pale rose-colour, and in a state of complete ramollissement through its whole extent, being in every part entirely diffluent. The medulla oblongata was tolerably healthy, except a slight degree of softening on its anterior part; and there was also a degree of softening on the tuber annulare, which seemed to involve the origin of the fifth nerve. Beyond this, the ramollissement became again more decided, extending along the crura cerebri and cerebelli, and considerably into the substance of the brain, at the part adjoining the crura. The brain, in other respects, was healthy, and there was no effusion in the ventricles. . It is difficult to trace the precise nature and progress of the affection of the cord, when the disease advances in so gra- dual a manner as in this case, and terminates in disorganiza- tion so complete and extensive. In tracing the history of the analogous disease of the brain, we found reason to believe, that it is originally an inflammatory affection of a low chronic character, seated in a small part of the cerebral substance ; that it may con-tinue for a considerable time in the state of simple inflammation, and then subside; or that it may termi- nate by a permanent change in the structure of the part, ge- nerally with some degree of induration. In this state we find it when the patient dies of another disease, as in Case CXXXV. When it is itself the fatal disease, it seems to be so by passing either into ramollissement, or into partial and unhealthy suppuration. It is probable that the same charac- RAMOLLISSEMENT OF THE CORD. 291 ter of disease takes place in the spinal cord; and it is found, in the same manner, sometimes in -a state of ramollissement, sometimes in the state of induration, and sometimes one part is*found indurated and another softened. In a remarkable case communicated to Ollivier by Andral, the affection began with numbness of the forefinger of the left hand, which gra- dually extended over the hand and arm. After some time the other hand and arm became affected in the same manner, and, after a year, the lower extremities. All the limbs then be- came paralytic, with permanent contraction but without loss of feeling. The legs were bent upon the thighs, and the thighs upon the abdomen, and the arms rigidly fixed across the thorax, with the points of the fingers pressed against the palms of the hands. If attempts were made to move the limbs from these positions, they were thrown into spasmodic contractions with much pain. The patient died in this state at the end of eight years from the commencement of the dis- ease. Along nearly the whole length of the cord, there was a central cavity€ull of a soft grey mucus. It was considered as arising from ramollissement of the grey central matter of the cord, and the parietes of the cavity were formed by the white matter in a healthy state. In a case by Ollivier, in which palsy took place in the same gradual manner, but affected only the lower extremities, the patient was confined to bed for seven years. His legs were drawn up upon his body, and were entirely motionless, but preserved their feeling. There was extensive ramollissement of the anterior pillars of the cord: and a very remarkable circumstance was, that the soft- enino- was greatest in the upper parts of the cord, the corpora pyramidalia, and several parts of the brain, and became less towards the lumbar portion. The intellectual faculties had been almost entirely obliterated, but the motion of his arms continued entire to the last. Such are the difficulties and ob- scurities cf this interesting subject. A different course of symptoms occurs* in a remarkable case described by M. Rullier.* A gentleman aged 44, who had slight curvature of the spine at the upper part, was seized with pain in the curved portion, which, after several remissions, increased rapidly, and was followed by sudden and complete palsy of both his arms. They became rigid, contracted, and entirely motionless, and the points of the fingers were forced * Journal de Physiologie, 1823. 292 RAMOLLISSEMENT OF THE CORD. against the palms of the hands. The sensibility of the parts was not impaired, and the lower extremities were not in the least affected, for the patient could walk about without diffi- culty. He lived six years in this state, and died of pectoral complaints. A portion of the cord, six inches in length, oc- cupying two-thirds of the cervical portion, and part of the dorsal, was entirely diffluent, so that before the membranes were opened, it moved upwards and downwards like a fluid. The posterior roots of the nerves of this portion preserved their nervous matter, to their junction with the membranes of the cord, but in the anterior roots it was destroyed, and they were reduced to an empty neurilema. Several other cases are mentioned in the same journal, intended to show the separate origin of the nerves of sensation and motion from the different parts of the cord. In one case, there was loss of power of the whole body without loss of sensibility, and the disease was in the anterior part of the cord. In another, there was complete palsy of the legs, and partial palsy of the arms, while the sen- sibility was everywhere morbidly increased. The medullary matter of the cord was singularly contracted in volume. The anterior part of its upper half was of a reddish-brown colour, and as it were macerated; the roots of the nerves inserted there were so wasted as to be scarcely discernible, while the posterior roots were preternaturally large. A case mentioned by Ollivier seems to establish the inflam- matory origin of the ramollissement of the cord, and at the same time shows the insiduous and dangerous nature of inju- ries of the spine. A man having suffered an injury of the spine by a fall, ten months after the accident had prickling of the left lower extremity, which ceased after a month, leaving it paralytic. The right lower extremity became affected in the same manner; and some projection of the vertebrae at the af- feeted part was thenfirst observed. Hehad afterwards convulsive motions of the limbs, and died about a month after the appear- ance of the palsy. On dissection, there was found false mem- brane of an inch in extent, with purulent matter betwixt the bone and the membranes of the cord at the affected part; and the portion of the cord included in the diseased membrane was entirely diffluent like cream. Above and below this portion, the cord was of a natural consistence, but highly injected, and of a deep red colour, especially below the softened part, where the redness was intense. RAMOLLISSEMENT OF THE CORD. 293 I shall conclude this part of the subject with the following very remarkable case, for which I am indebted to Dr. Molison. I did not see the patient during his life, but was present at the latter part of the inspection of the body, when the spinal cord was examined. I shall simply relate the case, without enter- ing upon any of the very interesting reflections which might naturally arise from it. Case CXLVIII.—A street porter aged 37, since February, 1827, had frequently complained of pain in his back, and in both sides of the thorax, with difficulty of breathing when mak- ing any great exertion. For a month before his death the pain of his back had been more severe, and he had great dif- ficulty of swallowing. His general health, however, was very little impaired ; and on Monday, 15th July, he carried a bur- den to Newhaven, three miles from Edinburgh, and afterwards went into the sea to bathe. While he was in the sea, as he afterwards stated, he became very confused, and, on attempt- ing to come out, fell among stones. When he was taken up, he was bleeding profusely at the nose and mouth; and, after he was carried to an adjoining house, he vomited blood in large quantities. Through the following night he was rest- less and partially insensible, and talked incoherently; he had several attacks which were represented as convulsive, in which his eyes became fixed, and there was much tremulous motion in his legs, but without any motion in his arms, which appear to have become paralytic at an early period of the attack. On the 16th, he was first seen by Dr. Molison: immediately be- fore his visit, he had brought up a large quantity of blood, which ran from his mouth in a full stream, and then coagulat- ed. He was somewhat lethargic, but distinct when roused ; and complained of pain in his head, chest, and bowels. His head and his legs were in almost constant motion, but his arms were paralytic, being entirely deprived both of motion and feeling. His breathing was easy; his pulse -frequent and small; countenance pale and anxious ; and he had involun- tary discharge of urine. In the evening, he again vomited blood in considerable quantities. (17th) There was little change, except that he recovered the power of the bladder; perfect palsy of the arms continued, but his legs were in al- most constant motion. There was no return of the vomiting of blood through the day; at night he fell asleep, and slept quietly for some' hours, when he awoke quite sensible ; but, 294 UNDEFINED SUPPURATION OF THE CORD. soon after, was seized with vomiting of blood to a great ex- tent, and died almost immediately. Inspection.—The heart and lungs were healthy ; the sto- mach contained a very large and firm mass of coagulated blood, which entirely filled it, and extended into the duodenum. In the descending aorta, about the 4th and 5th dorsal vertebrae, there was an aneurism the size of an orange, which had burst into the oesophagus by a large opening. The 3d, 4th, and 5th dorsal vertebrae were extensively carious in their bodies, where the substance was destroyed to the depth of a quarter of an inch. On opening the spinal canal, some bloody albumi- nous-looking matter was found between the bone and the dura mater of the cord, and between the dura and pia mater of the cord, there was a considerable quantity of a tenacious, sanious, bloody matter, which covered the surface of the pia mater, from about the 2d or 3d to the last dorsal vertebra. The substance of the cord, from about the 3d to the last dorsal vertebra, was of a yellowish colour, and in a state of extensive ramollisse- ment, especially about the centre of this space, where it was entirely diffluent. On removing the cord, the anterior part of the spinal canal, viewed from behind, presented several places where the bones were denuded of their covering and carious. This was most remarkable about the 3d, 4th, and 5th dorsal vertebrae. § III.—Undefined suppuration of the cord. It may perhaps be doubted, whether some of the cases which I have referred to this head, ought not rather to be referable to the ramollissement. These two morbid conditions were not accurately discriminated till lately; but in the brain there seems every reason to believe that they are entirely distinct; and it is probable that they may likewise be so in the cord. 1. A womati aged 23, who had suffered considerably from syphilis, was seized with severe quotidian intermittent, which proved very tedious, and resisted all the usual remedies. Af- ter some time, it was accompanied by pain in the lumbar re- gion, diarrhoea, tormina, tenesmus, general debility, and ema- ciation. About three months after the commencement of the fever, she began to be affected with weakness and convulsive motions of the left lower extremity, resembling chorea. In walk- ing, the leg was dragged, and, if she attempted, by a strong undefined suppuration of the cord. 295 effort, a greater degree of motion, it was thrown into convul- sive distortions. Soon after, the left arm became affected in the same manner, and there were also convulsive motions of the face and eyes. The complaint in the bowels now ceased, but the other symptoms increased, and the affection of the limbs soon amounted to nearly complete paralysis. She was then affected with difficulty of articulation, and diminution of memory; and these soon terminated in loss of speech, coma, and death, which was preceded by general and terrible con- vulsions. Her death happened rather more than a month af- ter the commencement of the convulsive affection of the leg. On dissection, some serous effusion was found in the thorax, and in the ventricles of the brain. The spinal cord was soft and flaccid, and to a considerable extent suppurated. Its in- vesting membrane was in many places covered by a puriform fluid; and there was also serous effusion in the spinal canal.* 2. A young soldier, who had lately recovered from a pete- chial fever, was affected with pain in the dorsal vertebrae, dif- ficulty of moving the lower extremities, retention of urine, in- voluntary discharge of faeces, general debility and emaciation. A variety of treatment was employed for several months with- out relief. * The weakness of the lower extremities increased to perfect paralysis ; and, soon after, the superior extremities became affected in the same manner. He then lost his speech, , and, after lying a fortnight in this state, completely immovea- ble and speechless, but in possession of his intellectual facul- ties, he died suddenly. On inspection, there was found no trace of disease in the brain, the thorax, or the abdomen. The spinal canal was inundated by a large quantity of sanious fluid. The cord itself was suppurated, dissolved, and disorganized, at the lower part of the dorsal region; above this, it preserv- ed its figure, but was very soft. Its investing membranes, and the periosteum lining the canal of the vertebrae, were de- stroyed at the part where the cord was so much diseased ; but the vertebrae and their ligaments were sound.* 3. A man aged 40, was received into the hospital of Crema, in the spring of 1804, with no other complaint than general weakness and depression, for which no cause could be assign- ed. He lay constantly in bed, but did not complain of any pain; his appetite was good; and he was free from fever. From being lean and pale, he became so fat and ruddy that * Brera Delia Rachialgite, cenni patalogici. In Atti dell' Accad. Ital. torn. i. 296 ABSCESS OF THE CORD. suspicions were entertained that he was feigning; but as win- ter approached, he became lean and cachectic. In February, 1805, he became completely paralytic, both in his legs and arms; and he died suddenly in March. On inspection all was sound in the head, the thorax, and the abdomen. In the spinal canal there was much effusion of bloody, sanious fluid, with marks of inflammation and suppuration in the spinal cord, the substance of which was remarkably soft, and tending to dissolution.* § IV.—Abscess of the cord. A woman aged 56. was affected with sudden loss of power of the limbs of the left side, without loss of feeling. It soon amounted to perfect palsy ; her voice became feeble, and her speech embarrassed; pulse natural; respiration quick. The left arm became cedematous. After four days the speech could not be understood; pulse feeble; increasing debility; stertorous breathing; and she died in a week. Inspection.—The brain was sound, but the pia mater was injected. In the centre of the right column of thei6pinal cord, in the middle of the cervical portion, there was a cavity three r inches long, and two or three lines in diameter. It was full of a soft matter like pus, which became more consistent to- wards the parietes of the cavity. It seemed to be the grey substance of the cord converted into pus. The parietes of the cavity were firm, and about a line and a half in thickness, and were formed by the healthy white matter. In the left column of the same portion of the cord there was a similar disease, but less extensive, being about one inch long, and one line in diameter; and its contents were less purulent, rather resem- bling ramollissement of the substance of the cord. The mem- branes of the cord were hardened at the part, and also at a part in the dorsal region.f * Brera, ut stcpra. f Valpeau Revue Medicale, 1826. SEROUS EFFUSION IN THE SPINAL CANAL. 297 SECTION III. SEROUS EFFUSION IN THE SPINAL CANAL. I place this appearance by itself, aostaining from any hy- pothetical speculations in regard to the origin of it. I have already alluded to the ambiguity which attends serous effusion when it occurs between the dura mater and the inner mem- brane of the cord, on account of the free communication which this space has with the cavity of the cranium, or at least with the cellular texture of the arachnoid of the brain. When the effusion is contained in the cavity formed between the dura mater and the canal of the vertebrae, there can be no doubt of its connexion with disease of the spinal canal. The following is the most distinctly marked case of this af- fection that has occurred to me. Case CXLIX.—A strong healthy child, aged nearly two years, after having been oppressed and feverish for two days, was seized with violent convulsion. The first fit continued about an hour, and left her comatose with distortion of the eyes. She had not recovered out of this state when she had another attack of convulsion, about two hours after the first. During the fits, and for some time after them, there was vio- lent and irregular action of the heart, and a pecular spasmodic action of the diaphragm. The second fit left her in a state of coma from which she never recovered. She took food or medicine when they were put into her mouth, but showed no other appearance of sensibility. The eye was completely in- sensible, and the pulse very frequent. She had afterwards several slight attacks of convulsion, and one more severe a short time before death, which happened thirty-three hours after the > first attack. Inspection.—No disease could be detected in the brain, ex- cept some appearance of increased vascularity, and slight ef- fusion under the arachnoid. The brain and cerebellum being removed, there was a copious discharge of bloody fluid from the spinal canal. The canal being laid open, there was found 38 298 SEROUS EFFUSION IN THE SPINAL CANAL. a copious deposition of colourless fluid, of a gelatinous ap- pearance, betwixt the canal of the vertebrae and the dura mater of the cord. It was most abundant in the cervical and upper part of the dorsal regions. Between the membranes of the cord there remained a small quantity of the bloody fluid which had flowed into the cavity of the cranium. The substance of the cord, at the upper part, seemed softer than natural, and very easily torn. All the viscera of the thorax and abdomen were perfectly healthy. The foramen ovale was pervious by a small opening. The effusion on the outside of the dura mater, in this case, was fairly to be considered as a distinct disease of the spinal canal; but the other effusion between the membranes, though somewhat more ambiguous, is not to be overlooked, especial- ly if we should find that this fluid is bloody, while the effusion under the arachnoid of the brain is colourless. In a child, aged between 3 and 4 years, mentioned by Ol- livier, who died with symptoms of opisthotonos, difficult deglu- tition, and coma, he found deposition of a red and very con- sistent fluid, in the cellular texture between the dura mater of the cord and the canal of the vertebrae in the dorsal region, serosity within the membranes, and the arachnoid of the cord covered with an albuminous concretion for four inches. The following cases are given by the eminent writers whose names are annexed to them, as examples of diseases depend- ing upon serous effusion within the spinal canal. 1. Morgagni mentions a man aged 40, who was affected with acute pain and weight in the lower dorsal vertebrae, the pain occasionally extending upwards or downwards to the top and bottom of the spine. After eleven days he was seized with paralysis of the right lower extremity, and in three days more with retention of urine. The pain was now so acute as to prevent him from lying down, and was soon after accom- panied by dispnoea, vomiting, and tonic convulsions of the trunk and arms, which recurred at intervals, and continued for about fifteen minutes. The left inferior extremity then became paralytic, and he died suddenly; his intellectual faculties had continued entire, except during the paroxysms of convulsion. On inspection much fluid was found in the cavity of the spine, SPINAL APOPLEXV. 299 but the cord was sound ; there was also fluid on the surface of the brain, but none in the ventricles.* 2. A child aged twelve months, whose case is briefly re- lated by Mr. Chevalier, after appearing to be in much pain, lost the use of the inferior extremities, and died in three days. The spinal canal was found full of bloody serum.f 3. Bonetus mentions a young woman, who, after suffering severely from colic, fell into paralysis. It began at the up- per part of the arms, and extended gradually to the points of the fingers. Afterwards the legs became affected, and she died of gradual exhaustion a year after the first appearance of paralysis. Through the whole extent of the spinal cord, there was a space betwixt its dura and pia mater, full of serous fluid. There was also some effusion on the brain.:): 4. A man, mentioned by Portal, had numbness of the infe- rior extremities, followed by paralysis of them, and extensive oedema. After some time the arms became affected in the same manner, and the oedema extended over the whole body. He died comatose. On inspection much fluid was found both in the brain and in the spinal canal. In the centre of the spinal cord there was a canal into which a large writing quill could be introduced. It was full of serous fluid, and extend- ed as far as the third dorsal vertebra. SECTION IV. SPINAL APOPLEXY, OR EXTRAVASATION OF BLOOD IN THE SPINAL CANAL. Case CL.—A child aged 7 days, 1st September, 1818, was observed not to suck, and appeared as if he were pre- vented by something which impeded the motion of his tongue. Throuo-h the following day he cried frequently, and still did not suck; in the evening he was seen by Mr. White, who found the jaw clenched by spasm, but by very little force it could be opened. On the third day he was seized with con- *Mor"-a on the spinal cord, this crust was more intense than in any of the other parts. M. Gen- drine, however, states, that he has assisted at the examination of many cases of hydrophobia, and never could discover any disease either in the spinal cord or the nervous ganglia. 6. Many cases of Dyspnoea are supposed by Frank to pro- ceed from disease at the origin of the phrenic nerves; and difficulty of speaking and of swallowing frequently depends, according to Portal, on " engorgement " in the cervical por- tion of the spinal cord. I leave these conjectures for the investigation of the reader, and shall hasten to bring this essay to a close, by a brief allu- sion to some points which seem to be related to the subject, * Rachetti della Strulura, dclle funzoni e delle Malattie della Midolla-Spinali. CONCLUDING OBSERVATIONS. 329 while they show the difficulties and obscurities which at- tend it. Several very remarkable cases have occurred to me which presented all the characters of extensive disease of the spinal cord, while nothing could be found, either in the brain or the cord, that could in any degree account for the symptoms. Several of the same kind, in which the symptoms.were equally decided, are mentioned by Dr. Bright. Case CLIV.—A woman aged 35, was first affected with numbness in the thumb of the left hand, which gradually ex- tended over the whole hand and arm. The limb was then par-1 tially paralytic, and was likewise affected with involuntary mo- tions exactly resembling those of chorea. This continued se- veral weeks, and then gradually ceased, and the arm recovered its healthy state. Almost immediately after this, the right hand and arm were affected in the same manner, and after some time also got well. The legs then became affected with start- ing, involuntary twitches, and a feeling in walking, as if they would start from under her to one side. The complaint went on in this manner for some time, and then terminated in complete paraplegia, with retention of urine, requiring the constant use of the catheter. She was now confined to bed for nine months, and died of extensive gangrene of the sa- crum and tops of the thighs. For some time before her death, she had recovered the action of the bladder. Inspection.—No disease could be discovered in the brain or the spinal cord, except that the cauda equina was of a very dark colour, as if it had been soaked in venous blood, and there was some bloody fluid around it. The sacrum was re- markably soft, and in some places carious ; and it was covered externally by a deep and extensive sloughing sore. All the other viscera were healthy. Case CLV.—A medical gentleman aged 30, who had been for several years in the navy, returned home in perfect health, and was living in Edinburgh, when he was observed by his friends to drag his legs awkwardly in walking. He was not himself at first sensible of it, but soon perceived a weakness and want of command over both his legs, which gradually increased to nearly perfect paraplegia. Some time after the affection of the legs took place, he began to lose the power of his arms, and this also increased, till he retained in them 330 PATHOLOGY OF THE SPINAL CORD. only a very feeble and unsteady power of motion. They were also frequently seized with convulsive startings, so that any article which he attempted to hold was thrown from him with violence. The legs often started in the same manner, and were thrown about with considerable violence, especially when he attempted to move them while he was sitting up. No dis- ease could be discovered in the bones of the spine, and he was otherwise in good health, until about two years after the commencement of the complaint, when he was seized with phthisis, of which he died in September, 1822. I examined the body with the utmost care, and could not discover a ves- tige of disease either in the brain or the spinal cord. Case CLVI.—A woman aged about 20, a servant, sprained her back in lifting some heavy article of furniture. She felt at the time no great inconvenience, but some time after, weak- ness of the legs took place, which gradually increased to perfect paraplegia. After some time the affection extended to the arms, and she then had not a vestige of motion of any of the parts below the head, except a very slight motion of some of the fingers ; but the internal functions were rall en- tire, and her speech was distinct, except that, in speaking, she was sometimes seized with spasmodic twitches of the lips and lower jaw. She lived in this state without any change in the symptoms, her general health continuing good, for about twenty years. In the morning she was taken out of bed, and placed in a chair so contrived as to support her in a sitting posture. Her arms were supported on a cross board which passed before her; and if, by any accident, one of them slipped from this support, she had no resource but to call the assistance of another person to replace it. Having been on one occasion left alone for about two hours, after one of her arms had thus slipped down, the hand had become ex- tensively cedematous. In the same manner, if her head fell forward upon the thorax, it remained in that position until raised by an attendant. Her mind was entire. She died of four days' illness, with symptoms of low typhus fever. I ex- amined the body with the utmost care, along with Dr. Pit- cairn, who had been in the habit of seeing her for several years, and we could not discover any disease, either in the brain or the spinal cord. Case CLVIL—A lady aged 30, had been liable for seve- CONCLUDING OBSERVATIONS. 331 ral years to a feeling of stiffness of her neck, with an uneasy feeling in the back part of it, which made her sometimes sit with her head bent very much forward, and at other times thrown backwards ; about two months before her death these feelings increased, and were accompanied by pain, extending along both the arms ; at first like rheumatic pains with stiff- ness, but soon amounting to paralysis. She had now only a very imperfect motion below the elbow, and could not raise either arm to her head ; there was very slight motion of the fingers, and they were sometimes spasmodically contracted. The speech became thick and partially inarticulate; she had considerable difficulty in swallowing, and she observed that there were certain positions of the neck, in which she could swallow with greater facility than in others. Her pulse was good, the other functions were natural, and the motion of the lower extremities was not at all affected. About a fortnight before her death, she became affected with dyspnoea, which occurred in paroxysms, sometimes very severe. An appear- ance of projection was now observed, with pain upon pressure in several of the lower cervical vertebrae. Issues were insert- ed in this place, and for a week she seemed better; she was free from dyspnoea, and the motion of the arms was consider- ably improved. On the evening of the 4th October, she be- came suddenly comatose with some convulsion, and had a pe- culiar convulsive motion of the lower jaw, which was for some time in a state of constant and rapid motion, opening and shutting with violence. The arms also became more paralytic. She seemed relieved after a bleeding, but, after two hours, sunk again into a comatose state, and died suddenly. Inspection.—In the upper part of the pharynx and larynx, there was a superficial redness like very recent inflammation ; but, on the most careful examination, no disease could be dis- covered in the brain, the spinal cord, or the bones of the spine ; and all the other viscera were in a healthy state. I shall add no comment on the simple relation of these re- markable affections, but merely illustrate them by an important case described by Bretanneau.* A lady, whose age is not mentioned, was affected with palsy in the little finger of the left hand, which gradually extended over the hand, and then over the arm. The left lower extremity then became affected * Revue. Medicale, May 1826. 332 PATHOLOGY OF THE SPINAL CORD. in the same gradual manner, and after this, the arm and leg of the right side, with the exception of the thumb and two fingers of the right hand, which preserved the power of motion. The motion of the tongue was then lost, and at last deglutition was much impeded. She preserved her intellect to the last, and expressed herself by moveable letters, which she arranged with the thumb and two fingers of the right hand, of which she preserved the power. The duration of the disease is not mentioned. There was a small quantity of fluid in the ven- tricles of the brain; but the brain itself, the cerebellum, and spinal cord, being examined with the utmost care, were found perfectly healthy, with the exception of a small spot upon the tuber annulare. On the right side of this, at the depth of four lines, there was a portion three lines in extent, of the colour of rust. Its centre was of the deepest colour, and its circum- ference irregular, gradually losing itself in the surrounding substance ; and it seemed rather harder than the other parts. The mobid appearance, in this singular case, has a remark- able resemblance to the morbid condition of a small part of the brain, formerly referred to, and exemplified in Case CXXXV. It is probably the result of a slow inflammatory action, limited to a very small portion of the cord, in the same manner as we have seen it in the brain. There is reason to expect, that a very minute examination of the whole cord, in such cases, may discover similar changes of structure, calculated to throw light upon affections which are at present involved in much obscurity. The following is one of the most remarkable that I find on record. A woman, mentioned by Ollivier, a servant, was suddenly seized while making a bed, with a very strong sense of prick- ing in the points of the fingers of the left hand, and the points of the toes of the left foot; and half an hour after, the same parts on the right side were affected in the same manner. She continued to go about for three hours, after which she was obliged to sit down from a feeling of fatigue ; and after sitting for some hours, she was carried to bed. Next day, there was paralysis of all the limbs, but in the greatest degree on the left side. The sensibility of the parts was not impaired. Re- spiration was performed with a kind of effort, and at night became very difficult. On the third day, respiration was ra- ther improved, but there was difficult deglutition. In the evening the difficulty of breathing increased, with frequent pulse and strong action of the heart, and she died at night. CONCLUDING OBSERVATIONS. 333 There was a slight appearance of infiltration of blood in the cellular tissue on the outside of the dura mater of the cord, es- pecially about the lower part. No other vestige of disease could be discovered either in the brain or the spinal cord; and all the other viscera were in the most healthy state. I conclude this subject with a brief allusion to certain ob- scure and anomalous affections, which, like those now men- tioned, present many of the characters of disease of the spinal cord, though their termination in general is more favourable. The affections assume a great variety of characters, and the nature of them is exceedingly obscure. The most common symptoms are various spasmodic affections of the limbs, or of the muscles of the back, sometimes resembling chorea, or even tetanus; and various degrees of weakness of the lower ex- tremities, sometimes amounting to complete paralysis, which is often accompanied by remarkable spasmodic affections of the paralytic limbs. There is generally a great feeling of weakness in the back, and frequently pain, which is sometimes confined to one part, but more commonly extends in a greater or less degree along the whole of the spine. Various affec- tions of the breathing likewise occur, sometimes with attacks of palpitation, and various uneasy feelings in the stomach and bowels. The affections occur almost entirely in females, chiefly those of the higher ranks, and are generally extremely tedious and untractable. It is indeed difficult to say what treatment has any decided control over them ; but the # remedies which appear to be most beneficial are, free and regular purging, or a combination of tonics and anti-spasmodics, with small doses of purgatives ; strong friction ; cold spunging or shower bath, and blistering on the spine. The affections commonly pass off, without leaving any bad consequences,—sometimes very suddenly, and without any cause to which their removal can be ascribed. One modification of these singular affections will be illustrat- ed by the two following cases, which lately occurred to me in the same family. A strong and healthy girl, aged 8, of a full habit and florid complexion, was observed to stumble fre- quently in walking, and occasionally to fall; and this, with- out any farther warning, was followed in a very few days, by perfect palsy of both lower extremities. I saw her about a fortnight after the attack, and found the limbs completely pa- ralytic, with frequent spasmodic contractions. Nothing was 334 PATHOLOGY OF THE SPINAL CORD. to be discovered about the spine, and she was in other respects in excellent health; the bowels were rather confined, but easily regulated. About a month after the commencement of this af- fection, her elder sister, aged 16, who had been rather deli- cate, and at times hysterical, was observed to walk awkward- ly, and, in a few days, she lost entirely the use of the lower extremities. She was now for some time in a great measure confined to bed, and the affected limbs were liable to strong spasmodic contraction ; her knees being drawn up to the abdo- men, and the heels to the buttocks. In this manner she lay du- ring the whole time while she was awake ; but as soon as she fell asleep, the limbs were stretched out into an easy, natural posture. She slept well in the night, but the moment she awoke, the limbs were drawn up into their contracted condition. If an attempt was made to extend them, great and continued force was required, until they were brought nearly to the ex- tended position, and then the complete extension took place with a sudden jerk. They now remained in this extended position for a few seconds, when they were by another sud- den and painful jerk thrown back into their contracted state. This young lady had also occasional spasmodic affections of the arms, and of the muscles of the neck; but these were transient, and there was no dimunition of muscular power in the arms. There was considerable uneasiness of the back, but nothing could be discovered by examination of the spine. Both cases continued in the state which I have described for nearly six months, and then got entirely well. The treatment consisted chiefly of free and continued purging with tonics, and antispasmodics, topical bleeding and repeated blistering on the spine. In the elder of the two, one of the blisters led to the formation of a large and troublesome carbuncle on the spine, and this seemed to accelerate the cure. I do not know whether the following case ought to be re- ferred to this class ; it excited my attention, as a very remark- able affection at the time when it occurred, and I have not seen another exactly resembling it. A gentleman aged 34, of a slender make and very active habits, was affected in the summer of 1815 with numbness and diminished sensibility of all the extremities. In the inferior extremities, it extended to the tops of the thighs, and sometimes affected the lower parts of the abdomen ; in the superior extremities, it never ex- tended above the wrists. There was along with it a diminu- tion of muscular power. He could walk a considerable dis- CONCLUDING OBSERVATIONS. 335 tance, though he did so with a feeling of insecurity and un- steadiness ; but he could not in the smallest degree perform swch motions as are required in running, leaping, or even very quick walking. He was in other respects in good health. Various remedies were employed, without benefit; evacuations and spare diet seemed rather to be hurtful. He had continu- ed in this state which I have described, for about two months, when he determined to try the effect of violent exercise. For this purpose, he walked as hard as he was able, five or six miles in a warm evening, and returned home much fatigued, and considerably heated. Next morning he had severe pains in the calves of his legs, but his other complaints were much diminished, and in a few days disappeared. He has ever since enjoyed very good health. These anomalous affections occur under other modifications considerably different from those which I have now described. I received from my friend, the late Dr. Monteith of Glasgow, a very interesting account of two cases which occurred to him under a very aggravated form. One of these, a lady, aged 22, was at first affected with violent headach, accompanied by a sense of tension in the head, and strong throbbing in the ca- rotids, temporal arteries, and throughout the head ; the pulse 120. Large and repeated bloodletting was employed for the first ten or twelve days, until she was "pale as paper," and exceedingly enfeebled, but without any relief. After four weeks, she became affected with violent pain in the lower ex- tremities, which were drawn up and could not be extended, the thighs being drawn up to the abdomen, and the legs bent back upon the thighs ; and every exacerbation of the headach was followed by an increase of irritation, pain and retraction of the limbs. The headach was chiefly referred to a spot upon the left parietal bone, where she had received an injury by a fall three months before. A variety of practice was employed with very little benefit: and her only relief Was from blood- letting, and large doses of laudanum, of which she sometimes took 500 drops in the course of a night. Mercury appeared at one time to be productive of some benefit; the effect, how- ever, was only temporary, though she went through repeated courses of it. She used prussic acid to a great extent, the warm bath, and a variety of other remedies with very little benefit. At the end of about three years, the limbs for the first time became so free from pain and irritation as to bear 336 PATHOLOGY OF THE SPINAL CORD. applications with the view of remedying the stiffness of the joints; and, at the end of about three years more, she was gradually restored to perfect health. This lady was not for an hour free from headach for three years, but besides this constant pain, she was liable to violent exacerbations of it, lasting from a few days to several weeks. During these at- tacks the pulse became very strong and jarring, and the face flushed and swelled ; and the only relief she obtained was from repeated bloodletting, so that in the course of her illness she was bled from the arm ninety-eight times, besides frequent topical bleeding by leeches and cupping. The other patient was a young lady of 17, whose complaints also began with violent headach, for which she underwent a great variety of treatment for upwards of twelve months, without any permanent benefit. On the contrary about the end of this period, the pain rather increased, and she was confined to bed in a state of extreme exhaustion, and suffering from constant and intense headach. Soon after, she first com- plained of pain in the spine, and this was speedily followed by a sudden attack of most excruciating pain in both lower extremities, extending over every part of them, and accompa- nied by such increased sensibility that she could not bear the weight of the bedclothes upon them, and the slightest touch with the finger made her scream. There was also tenderness and morbid irritability of the trunk and upper extremities, so that she could not allow the arm to remain fully extended during the short time of feeling her pulse. From the com- mencement of this affection of the limbs, they began to be powerfully retracted, and after a short time they were drawn up close to the body; and there was severe pain extending along the whole course of the spine, where, however, no dis- eass could be discovered on examination or by pressure. She now became much emaciated, pale and debilitated; the head- ach was rather relieved, but the limbs continued in the same state, and the slightest touch upon them, or the most gentle attempt to extend them, gave such violent pain, that, for eight months, Dr. Monteith said, she was not moved in bed six inches. At the erid of four years, this lady began to improve, and to get out of bed a little daily; but at this time her legs were so much bent upon the thighs, and the knees so rigid, that no force could bring them to a right angle. At the end of three years more, Dr. Monteith's report of her was, that she could walk a short way, and was progressively improving, CONCLUDING OBSERVATIONS. 337 so that he entertained sanguine hopes of a complete recovery. I visited this lady along with Dr. Monteith in the course of her illness, and I certainly never saw a case which gave me more the impression of deep-seated and hopeless disease. The history of these cases conveys a more distinct impres- sion of this extraordinary affection than could be given by any description. Other varieties of the symptoms were observed in some of the other cases which occurred to Dr. Monteith, particularly long-continued' and uncontrollable vomiting, fits resembling epilepsy and catalepsy, palpitations and various irregular actions of the heart, and a strong and painful pulsa- tion extending along the whole course of the spinal cord. There were also irregular attacks of fever, fits of colic, and severe spasms in the abdomen, which were relieved only by large opiates. There was in general a remarkable aversion to light, and one of his patients lay in a state of almost total darkness for more than a year. In another patient, a lady of 30, the arms were affected, but not so severely as the lower extremities. This lady was confined to bed for two years, and then recovered perfect health, which she had enjoyed for five years at the time when I received this account. In an- other there was such incessant vomiting that she retained no- thing in the form of food, drink, or medicine, for six weeks. In this case the vision was also very much impaired, and twice suspended for a very considerable time. Nothing was to be discovered about the spine in any of these cases, and the pain in the spine was not increased by pressure, but it was very much increased by motion, or by attempting a sitting posture. In the treatment, temporary benefit was experienced from bloodletting, very large opiates, and warm bath ; but, upon the whole, the disease seemed gradually to wear itself out, without any mode of treatment having a sensible effect in arresting its progress. Even after considerable improvement has taken place, the disease is apt to relapse from very slight causes. In one of Dr. Monteith's cases, a cure was so far accomplished in eighteen months, that a drive for a short way in a carriage was then recommended; but this produced a relapse, which lasted another year, and was fully as violent as the first. This affection has been described by Dr. Burns of Glasgow; and he mentions some other symptoms as occasionally attend- ing it in his observation, such as attacks of dyspnoea, resem- bling croup, temporary loss of speech, and of the power of swallowing, and temporary aberration of mind. He agrees 338 PATHOLOGY OF THE SPINAL CORD. with Dr. Monteith, in regard to the tedious and untractable character of the disease, and confesses, that, " in most cases, he has not seen decided advantage from any medicine, be- yond what was required for symptoms as they arise, time ap- pearing the chief remedy." I find an analogous affection described by Dr.' Guerin of Mamers, in a tract " Des Irrita- tions Encephaliques et Rachidiennes." One of his patients, a young man of 16, had first attacks of palpitation and difficult breathing, then violent pains in the upper part of the abdomen, and, after six months, attacks of loss of recollection, with convulsive motions of the arms, grinding of the teeth, and vi- olent palpitations of the heart. These attacks continued to recur at uncertain periods; and, during the intervals, he did not entirely recover, from the effects of them. He continued depressed and incapable of any mental exertion, unable to bear the least light or noise, and the attacks were excited by any exertion or mental emotion. The patient continued in this state for upwards of four years, and then gradually and completely recovered. The principal remedies employed were purgatives, topical bleeding, prussic acid, and vegetable diet. In another case, very similar, in a young man of 20, he found benefit from the use of cold effusion. I have frequently seen in young females a slighter affection, in which there was pain referred to various parts of the spine, sometimes chiefly to the lower part of it, and sometimes ex- tending upwards and downwards along the whole course of the spine. There was generally some degree of weakness of the limbs, with great disinclination to walking, sometimes with spasmodic twitching of the toes, especially in the night- time. I have treated such cases by topical bleeding and blis- tering, without benefit; and I have generally found the most effectual treatment to be regular but moderate purging and sea-bathing. Attempts have been made to explain these singular cases, by the doctrine of spinal irritation. But it may, perhaps, be doubted, whether this conveys any definite notion, or whether it is not to be considered as a gratuitious principle, assumed so as to answer to the phenomena, rather than deduced from observation. When we find, along with the complaints now mentioned, symptoms distinctly referable to the spine, as pain or tenderness on a particular spot, it is fair to consider this as directing our attention to an important seat of disease; but CONCLUDING OBSERVATIONS. 339 there is no doubt that these affections often appear, without any symptom that can be referred to the spine, and in many cases with sources of irritation, distinctly referable to other organs. A gentleman, about whom I was consulted some time ago, had a severe and long-continued attack of nephral- gia, which was at last relieved by the passage of a calculus; but such a degree of inflammatory action had been excited, that, for several weeks after the violence of the attack had subsided, he discharged purulent matter in his urine, in large quantity. In the course of the complaint, and about the time when the violent pain, which was in the region of the left kidney, was beginning to subside, he was affected with diffi- culty of swallowing, a sense of constriction in the oesophagus and the pit of the stomach, and spasmodic affections of both upper and lower extremities, and of the left side of the face, closely resembling tetanus. These continued in a greater or less degree for eight or ten days. But it is chiefly in females that these anomalous spasmodic affections are met with ; and in these, one of the most re- markable features of them, is the connexion which they have, even.in their most aggravated forms, with the state of men- struation. The following case will illustrate this in a striking manner, and at the same time exemplify some of the various forms which are assumed by these singular affections. Case CLVIIL—A lady, now aged 28, in the year 1823, was first affected with numbness and partial loss of power of the right arm and leg, and some time after had slight difficulty of articulation.- These symptoms subsided under the usual treatment, and returned after some months, when they affected the legs and arms of both sides, and had more of the charac- ters of chorea. After another interval of several months, she became'liable to attacks of blindness, which were occasioned by a falling down of the upper eye-lids, so that she could not raise them; and when they were raised by the hand, the eyes were found to be distorted upwards. These attacks generally continued for several weeks at a time, and were relieved by cupping on the temples. With these symptoms the two first years of her illness pass- ed. In the third year she was affected with convulsive ac- tion of the muscles of the back, and involuntary twitches of the legs and arms, producing convulsive motions of the whole body, which it is impossible to describe. These were much 340 PATHOLOGY OF THE SPINAL CORD. increased by touching her, especially on any part of her back ; also by laying her upon her back, or even by approaching her as if with the intention of touching her. At one time there wTas difficulty of deglutition, so that attempts to swallow pro- duced spasms resembling tetanus. At other times, after lying * for a considerable time quiet, she would in an instant throw her whole body into a kind of convulsive spring, by which she was thrown entirely out of bed; and in the same manner, while sitting or lying on the floor, she would throw herself into bed, or leap on the top of a wardrobe fully five feet high. During the whole of these symptoms, her mind continued en- tire, and the only account she could give of her extravagance, was, a secret impulse which she could not resist. After a considerable time these paroxysms ceased, and she was then affected with convulsive motions of the muscles of the upper part of the back and the neck, producing a constant rotatory motion of the head. This sometimes continued with- out interruption night and day for several weeks together, and if the head or neck were touched, the motion was increased to a most extraordinary degree of rapidity. During the attacks, she could not sleep, except in the sitting posture, the motion continuing during this imperfect sleep, though in a more mo- derate degree; but if she happened to slip down, so that her head touched the pillow, she instantly awoke with a severe convulsive start, and the motion was increased to the greatest degree of rapidity. These paroxysms were relieved by no- thing but cupping on the temples to the extent of 10 or 12 ounces, when the affection ceased in an instant, with a gene- ral convulsive start of the whole by. She was then immedi- ately well, got up, and was able to walk about in good health for several weeks,—when the same symptoms returned, and required a repetition of the same treatment. Sometimes from the violence of the motion of the head, it was impossible to cup her on the temple. In this case, the cupping was applied first on the back; and by this, the motion was so far moderat- ed, as to allow it to be applied on the temple, without which the paroxysm was never removed. Bleeding from the arm to the extent of faintness only moderated it for a time, but did not remove it. Another very singular feature of the affection was, that it subsided fully only when it went off in an instant, with a sudden convulsive start of the whole body: when it subsided gradually, as under the influence of large bleeding, CONCLUDING OBSERVATIONS. 341 it returned as soon as the faintness from the bleeding was removed. The affection went on in this manner, with intervals of tole- rable health of a few weeks' duration, for about four years, be- sides the two years formerly mentioned. The longest inter- val was one of about three months, but even during these * intervals various convulsive motions were excited by slight causes. Menstruation was all along extremely irregular and very scanty, and the bowels were torpid. She was of a pale and bloodless aspect from the frequent bleedings, but not re- duced in flesh. I saw her only at an advanced period of the disease, along with Mr. Gillespie, who had watched her through its whole progress, and by whom every variety of treatment had been employed with the utmost assiduity. At last, in the spring of 1829, we found her under a severe paroxysm of the rotatory motion of the head ; when it was de- termined to allow the attack to take its course, and to direct our attention entirely to the menstruation. With this view she began to take three grains of sulphate of iron three times a day, with two grains of Barbadoes aloes,—the aloes being af- terwards diminished according to the state of the bowels. She went on with this for nearly three weeks ; the convulsive mo- tion of the heacf continuing without intermission night and day. At length, in the middle of the night, the paroxysm ceased in an instant, with the same kind of convulsive start of the whole body with which it used to cease after cupping. At the same instant menstruation took place in a more full and healthy manner than it had done for many years. She has continued from that time free from any return of the affection. I conclude this subject with the following case, which shows another form of this affection. If we were required to give a name to this modification, we could probably call it no- thing but a very aggravated form of hysteria. Case CLIX.—A young lady aged 15, in October 1828, was thrown from a horse, but did not appear to sustain any injury except a contusion of the arm, and she did not com- plain of any thing else for a week after the accident. At the end of the week she fell asleep in her chair one evening, and awoke in a state of incoherence, talking in a wild, extravagant manner, and appearing totally unconscious of the presence of 342 PATHOLOGY OF THE SPINAL CORD. those who were about her, and entirely occupied with her own hallucinations. This condition continued in a greater or less degree for three weeks, notwithstanding much active treatment by bleeding, purgatives, &c. The bowels were throughout remarkably torpid. She then began to recover, ' and went on in a state of progressive improvement for about three weeks, when one evening she fainted, and on recovery was found to be in the same state of incoherence as before.— This paroxysm continued] a fortnight, and was succeeded by another fortnight of convalescence, when the affection was re- produced by the patient being told of the illness of a near re- lative. During the paroxysms she generally complained of intense headach, which was chiefly referred to the occiput; the pulse varied from 90 to 120 ; the tongue was white ; the bowels torpid and motions unhealthy; her nights were sleepless. Af- ter the third of the paroxysms now mentioned, her conva- lescence was less perfect than formerly, there being generally a good deal of excitement in the evening, and very restless nights. In the end of January 1829, after much previous ir- ritation, she fell into a state of coma, with flushing. This continued several days, and was succeeded by a state resem- bling catalepsy; the eyes being continually fixed in one di- rection but without perception ; total unconsciousness of any thing that was done about her ; and the jaws so firmly locked that she swallowed nothing for several days. The jaws then gradually relaxed, and she recovered the power of swallow- ing ; after several days more she began to speak, after having spoken none for 13 days, and then went on gradually improv- ing for some weeks. The comatose state then returned, and was succeeded as before by the cataleptic, the jaws being again rigidly contracted, and the under lip drawn between the teeth so as to be wounded; the face and neck were flushed and turgid. This attack subsided after bleeding, &c, and was succeeded by cataleptic paroxysms of a slighter kind, which were excited by various causes, such as the sight of a stranger or any degree of mental irritation. In these attacks she became suddenly silent and motionless, the eyes open, but fixed and insensible, with total unconsciousness of every thing; the hands clenched and the arms drawn towards the body. She continued in this state from a few minutes to half an hour, and generally came out of it with a scream and with- out any recollection of the attack, or of the circumstance CONCLUDING OBSERVATIONS. 343 which had excited it. In the middle of March she became again incoherent and unmanageable, and this alternated with the cataleptic attacks till the middle of April, when a new set of symptoms commenced. While lying in the cataleptic state, she would suddenly, and by a convulsive motion, raise her body into a sitting posture, the head projected forward, the tongue protruded, and the countenance much distorted; the hands clenched and firmly pressed on each side of the trachea. During these attacks respiration seemed nearly suspended for some minutes, and in her convulsive efforts to breathe, she sometimes raised herself into a standing posture, and required the care of several attendants to prevent her from throwing herself out of bed. These paroxysms returned frequently and at short intervals, and were relieved only by bleeding from the temporal artery. After some time they ceased, and were suc- ceeded by the slighter cataleptic attacks excited by va- rious slight causes. It was at this period of the complaint that I first saw her along with two eminent medical men who had the charge of her; from that time there was no return of the violent paroxysms ; and there was a gradual improvement in her general health, which could not be ascribed to any other cause than a change of scene, and sending her regularly out into the open air. The attempt to do this at first excited the cataleptic state, and she continued totally insensible the whole time she was in the carriage. But we persevered, and this gradually subsided, so that she was soon able to take a long drive without exciting it, but there was generally some recur- rence of it before she returned home. The slighter paroxysms Were still excited by the sight of a stranger, or by any cause of mental agitation. During these her body became motion- less, but without losing her balance, though she was sitting on a chair without leaning to the back of it, and even in some instances while she was standing. The eyes were open, fixed, and insensible; the arms generally rigid, but sometimes re- laxed, and the attack continued from a few minutes to half an hour. She was also seized occasionally, while walking, and continued to walk on steadily, leaning on the arm of another person, and even walking alone, and often came out of the fit without stopping. She was also repeatedly seized while playing on the piano, and continued to play with perfect cor- rectness, but repeating a certain part of a tune, and never go- ing on beyond a particular point. This she sometimes con- tinued to do for ten minutes at a time, during which period 344 PATHOLOGV OF THE SPINAL CORD. she was totally unconscious of any external impression. On one occasion she was playing from,the book a piece of music which was new to her, and had played a part of it when she was seized with the cataleptic attack. During the paroxysm she continued to play this part, and repeated iUive or six times in the most correct manner; but when she recovered from the attack, she could not play it without the book. The cata- • menia, in this case, were rather irregular, and at times scanty, but occurred in a very natural manner several times during her illness, which, at the time to which this account refers, had continued ten months. Soon after that time, she was re- moved to a distant part of the country, and I have heard of her only occasionally. But I understand she has never been entirely free from the affection, though the symptoms are now in a slighter degree. I make no apology to practical men for these long details, as the affections are of a very uncommon kind, and as it is impossible to convey any idea of them by a general descrip- tion. There are other modifications presenting very singular characters, but I must allude to them very briefly. A young lady, whom I saw with Mr. William Wood, along with some symptoms resembling chorea, was liable to paroxysms, in which she screamed out the sound, echum, echum, echum, with great rapidity, and in a tone of voice that was heard over every part of a large house. These paroxysms often continued for one, two, and even three hours at a time, and occurred re- peatedly during the day, and sometimes in the night. They were excited by any sudden noise, or the sight of a stranger; and in the night-time not unfrequently by the striking of a clock. Her mind was quite entire, but she had no control over the affection, except that during the paroxysm she could change the sound when she was requested to do so, and sub- stitute any other word that was suggested to her. The affec- tion went on for many months, and then gradually subsided. We could scarcely say that medical treatment was of any avail. It consisted chiefly of a long-continued course of pur- gatives. For a considerable time after her recovery, though she was not at all affected by her disorder being talked of, she showed the greatest dread of the sound echum being repeated in her hearing. Another lady, whom I saw with Dr. Poole, was liable to paroxysms of rapid and laborious breathing with a loud shrill sound, and the appearance of the utmost distress, as in the CONCLUDING OBSERVATIONS. 345 most aggravated form of croup. They came on without any warning, when she was in perfect health, and if not relieved, continued for days together. They were relieved by nothing but bloodletting, but in several instances, a bleeding of three or four ounces was sufficient; and on one occasion, the attack was removed by a puncture of the arm, when no blood was obtained, or only a few drops. The affection subsided gra- dually after continuing to recur in this manner for more than a year. A case of much interest has been related by Dr. Follet of Namur. A strong country woman being much terrified during the flow of the menses, the discharge was suddenly suppressed. After four months, she experienced creeping sensations', spasms, and involuntary motions of the lower extremities; and in the following month, the limbs became forcibly bent, so that the heels touched the buttocks, and every attempt to extend them produced the most acute suffering. These symp- toms continued five days, and then subsided ; but they were renewed at the same period in the succeeding month, and sub- sided after the same duration, but left a degree of paraplegia. The attacks were afterwards moderated by repeated topical bleeding, vapour bath, &c, but the affection continued in a greater or less degree for six or seven months. Menstruation having then taken place in a full and healthy manner, her complaints entirely disappeared.* * Medical Gazette, vol, i. 44 APPENDIX TO PART FOURTH. OUTLINE OF THE DISEASES OF NERVES. Nearly allied to the pathology of the spinal cord, is ano- ther subject of very great interest, the pathology of nerves.— This subject is entirely in its infancy, but the investigation seems to promise very interesting results. From what we al- ready know, there is every reason to believe, that nerves are liable to diseases analogous to the diseases of the brain and of the spinal cord, which may affect them either in their sub- stance or in their membranes, and are probably the source of several diseases which are at present involved in much] ob- scurity. In as far as this subject has hitherto been investigated, the following may be considered as the principal idiopathic dis- eases of nerves which have been observed. I. A uniform dark red colour of the nervous substance, oc- cupying a defined space, perhaps an inch or two in extent.— This was observed by Martinet,* in the median nerve, in a case in which there had been violent pain of the fore-arm, followed by palsy. Repeated blisters removed the paralytic affection, but, as soon as the blisters healed, pain returned, fol- * Revue Medicale, Juin, 1814. 348 OUTLINE OF THE DISEASES OF NERVES. lowed by palsy. In a similar affection of the right sciatic nerve, accompanied by palsy of the limb, he found a diseased portion of nerve enveloped in a quantity of gangrenous cellu- lar tissue. In another case he found a diseased portion of the crural nerve, which was an inch and a half in extent, en- larged to about double its natural size. This portion was of a violet red colour, and strewed throughout with small ecchymoses each about the size of a pin's head. II. Serous or bloody effusion within the sheath of the nerve, penetrating the substance of the nerve, and separating its fibres from each other. This appearance was found by Mar- tinet in the sciatic nerve of a man who died of pneumonia; he had been affected with violent pain in the posterior part of his thigh, aggravated by the least motion* so as to make him cry out. III. Pus effused in the same manner among the fibrils of the nerve. This was found in the sciatic nerve by Martinet, in a man who died of disease both in the head and in the ab- domen, and who had been affected during the latter part of his illness with violent pain in the course of the sciatic nerve. The cellular texture surrounding the diseased portion of the nerve was also penetrated by pus. He found the same appear- ance in a young man who died of consumption, and who had been affected for two months with lancinating pain, and a painful feeling of numbness extending from the ham to the top of the thigh. IV. Ramollissement of the nervous substance.—A man, mentioned by Descot,* died in the Hotel Dieu, after he had been for six months blind of one eye. The optic nerve was found reduced through half its extent to a liquid matter of a white colour. V. Ulceration of the substance of the nerve was observed by Mr. Swan in connexion with a fungous ulcer on the leg.— There had been such violent pain of the whole leg and thigh, as to render amputation necessary, and, in many parts of the limb, the nerves were found very much enlarged.f * Descot, sur les Affections Locales des Nerfs. t Swan on the Local Affections of the Nerves. OUTLINE OF THE DISEASES OF NERVES. 349 VI. Small tumors attached to nerves, and productive of violent symptoms, have been described by various writers. In a remarkable case by Portal, a woman was cured of epilepsy by the removal of one of these tumors from the thumb. The slightest pressure upon it gave great pain, and frequently brought on an epileptic attack. The removal of such a tumor however from one of the axillary nerves by Sir Everard Home, terminated fatally; and the safer mode of treating such affec- tions appears to be to remove the portion of nerve entirely to which the tumor is attached, when the nerve is so situated as to render such an operation advisable. Small tumors or tu- bercles have also been found on internal nerves. Sedillot found one in the optic nerve, in a case of amaurosis; and Berard has described a black tumor as hard as scirrhus developed in the substance of the diaphragmatic nerve. The man had been asthmatic, but he had also slight emphysema of the lungs. These tumors'are generally very small; but there is another species of tumor which grows to a considerable size. One, mentioned by Mr. Pring,* the size of a pigeon's egg, was cut out from the arm, by dividing the nerve above and below. On cutting into it, an expansion of the substance of the nerve seemed to form an imperfect cyst, which contained a medulla- ry and fatty matter, and the filaments of the nerve were con- tinued over it. There had been great numbness and loss of power of the arm, but it gradually improved after the opera- tion.! VII. Nerves have been found both very much enlarged and very much diminished in size; and they have been in a few instances found with the nervous substance destroyed, the membrane at the part forming an empty canal. But these points have not yet been sufficiently investigated. Few opportunities have as yet occurred of ascertaining the condition of the nerve in those interesting cases of local pa- ralysis, which have been so beautifully illustrated by Sir Charles Bell, and his lamented friend the late Mr. Shaw. It is probable that there is either an inflammatory action in the * Pring on the Nervous System. t Fob a very full and able account of these tumors, and other diseases of nerves, I refer to a paper by Mr. William Wood, in the Transactions of the Medico-Chirurgical Society ofEdinburgh, vol. ii. 350 OUTLINE OF THE DISEASES OF NERVES. nerve itself, or its coverings ; or that the nerve is affected by disease of some of the parts through which it passes. The only case in which I have had an opportunity of examining the parts, since I was acquainted with the discoveries of Sir Charles Bell, was in a woman about 40 years of age, who died of organic disease of the stomach. About a fortnight before her death, she was seized with twisting of the mouth and paralysis of the orbicularis of the left eye. She had after- wards considerable indistinctness of speech, and, before her death, there was inflammation of the left eye, with an evident tendency to sloughing of the cornea. A small hard tumor was felt under the ear, deeply seated betwixt the angle of the jaw and the mastoid process. On dissection no disease could be discovered in the brain. The tumor under the ear was found to be the size of a small bean, very firm, of an ash- colour ; and, when cut across, it discharged thin puriform sa- nious fluid from minute cells in its substance; it lay directly above the facial branch of the portio dura; and there was considerable appearance of inflammation in the cellular struc- ture surrounding the nerve ; but I could not discover any de- viation from the healthy structure in the nerve itself. I thought it was dimininished in size at the place where the tumor lay over it, but in this I might be mistaken. In a case by Descot, connected with extensive suppuration and caries of the audi- tory portion of the temporal bone, a part of the portio dura was entirely destroyed ; and in a case by Billard, connected with an unhealthy abscess of the parotid gland, the course of several of the nervous branches was interrupted by destruction of part of their substance. An epileptic patient, mentioned by Serres, had inflammation followed by opacity of the right eye, loss of feeling of the conjunctiva, and insensibility of the right nostril, and right side of the tongue. He died of an affection of the brain; and, on inspection, the fifth pair of nerves, at its origin, was found yellow, softened, and reduced to a state almost gelatinous. • The important practical application of the discoveries of Sir Charles Bell is, that there may be paralysis of the muscles of one side of the face, producing distortion of the mouth with inability to shut the eye-lids, without disease of the brain, and consequently without danger. This affection de- pends upon a disease limited to the portio dura of the seventh OUTLINE OF THE DISEASES OF NERVES. 351 nerve, and may be produced by inflammation of the ear or the parotid gland, or tumors compressing the nerve on any part of its course. The most common example of it seems to originate in a kind of rheumatic inflammation produced by cold, especially by exposure to a current of cold air, as when a person has sat long, or has slept, opposite to an open win- dow, or has sat in his carriage with a cold wind blowing on one side of his head. It is to be treated chiefly by local re- medies, as topical bleeding, blistering and the application of warm water or steam. In this manner it is often speedily removed, but in some cases proves tedious, and does not go off entirely for several months. The affection is of course still more untractable, or even permanent, when it depends upon a permanent cause, such as tumors compressing the nerve, or destruction of a portion of the nerve by wounds or extensive suppurations. There is also a very formidable mo- dification of it which depends upon disease of the temporal bone. • The character by which these cases are distinguished from paralysis depending upon disease of the brain, consists chiefly in the sensibility of the parts remaining unimpaired. The loss of motion also is confined to the muscles of the face and eye-lids, and does not affect those of the jaw. These pecu- liarities arise from the remarkable fact demonstrated by Sir Charles Bell, Mr. Shaw, Mr. Mayo, and others, that the por- tio dura of the 7th is a nerve of motion only, supplying the muscles of the face and the orbicularis of the eye, but not the muscles of the jaw ; and that the sensibility of all these parts, and the motion of the muscles of the jaw are derived from the 5th, which having a double origin, is a nerve both of sensation and motion. An important distinction, however, is to be kept in mind with regard to the paralysis of the eye- lids which occurs in these cases, namely, that it is the ina- bility to shut the eye that arises from the affection of the por- tio dura of the 7th. The dropping of the upper eye-lid and inability to raise it is a disease entirely of a different nature ; it depends upon an affection of the 3d nerve, and conse- quently gives more reason to suspect disease within the head. When, therefore, we find paralysis and distortion of the face, with loss, of sensation of the parts, we have reason to suspect disease within the head, the portio dura of the 7th and the 5th being both affected. But when we have the para- 352 OUTLINE OF THE DISEASES OF NERVES. lysis without diminution of sensation, the disease depends upon an affection of the portio dura alone, and may be en- tirely without danger. Such cases, however, are not to be treated lightly, but the cause of them ought to be carefully investigated; for if there be any reason to suspect that the affection depends upon disease of the temporal bone, it may come to be attended with danger by inflammatory action spreading inwards to the dura mater or brain. There is an- other modification also which requires to be watched with anxiety, namely, when the affection is accompanied with deafness ; as this gives reason to believe that both portions of the 7th nerve are affected, and consequently to suspect an in- ternal cause. A very interesting case of this kind occurred some years ago in the Infirmary of Edinburgh, under the care of my lamented friend the late Dr. James Gregory. Two years before his death, the man had received a blow on the right ear from a stone, after which he had a purulent discharge from the ear for six months. He then gipdually lost the hear- ing of that ear, and about the same time the right side of his face became paralytic without any diminution of sensibility, and the action of the masseter and temporal muscles was un- impaired. Without any farther change of these complaints he died of phthisis in April, 1829. The petrous portion of the temporal bone was found most extensively destroyed, leav- ing an excavation which contained foetid purulent matter and portions of dead bone. The 7th nerve was traced from within to the margin of this excavation, where it terminated, and the portio dura, in the same manner from without, the intermediate portion being destroyed. The parts of the nerve that remained seemed entirely healthy. The brain and dura mater were sound. For some time before his death the pa- tient suffered greatly from dyspnoea, during the severity of which the ake of his left nostril were in strong and constant action, while those of the right were perfectly still. If this man had^ not been cut off by the disease of his lungs, the affection of the temporal bone would probably have termi- nated fatally in no long time, by inflammation of the dura mater. I am indebted to Dr. Christison for a very important case which occurred to him in the Infirmary of Edinburgh in the beginning of the year 1829. The patient, a man of 30, was seized in the beginning of 1825 with acute pain, referred to a OUTLINE OF THE DISEASES OF NERVES. 353 circumscribed spot on the left temple. About a week after, he had loss of speech followed by coma. He came out of this with loss of the memory of persons, but gradually recovered, and was well in less than two months. In the end of 1827, he was again seized with pain in the temple, accompanied by deafness of the left ear and squinting of the left eye. The deafness was permanent; the pain and squinting subsided after three or four months, but returned after two or three months more, accompanied by inability to close the eye-lids of the left side, and considerable unsteadiness in his gait. He was next affected with pain and rigid contraction of the muscles of the back of the neck and right shoulder ; and these were followed by retention of urine and perfect paraplegia. He had now the usual paralytic state of all the parts supplied by the portio dura of the left side, with deafness of the left ear, distortion of the left eye ir^svards towards the nose, and frequent spas- modic twitches of the jaw, by which it was drawn to the right side; and he .died in a state of coma in February, 1829. On inspection there was found immediately behind the left tem- poral fossa, a thickening of the dura mater with adhesion to the arachnoid of the extent of a half-crown piece. There was a similar adhesion, with very great thickening of the dura mater above the pars petrosa of the temporal bone, and the left side of the tentorium was also very much thickened, and presented on its inferior surface several tubercular eleva- tions. The thickening of the dura mater was greatest at the part where it is perforated by the seventh nerve, and the sixth nerve was also involved in the disease. The portio mollis of the seventh was, for a few lines previous to its entrance into the meatus, of a reddish-grey colour, and nearly gelatinous consistence; the portio dura seemed smaller than usual. In the substance of the right hemisphere, nearly on a level with the ventricle, there was a tubercle the size of a French bean ; and there was a small cyst in the right corpus striatum. In the posterior cornu of the right ventricle, there was a peculiar appearance, as if a portion of it had been obliterated by adhe- sion, cutting off a very small cavity about the size of a lemon- seed, which communicated by a narrow opening with the ven- tricle, and presented at each extremity a yellowish line or raphe resembling a cicatrix. No appearance of disease could be detected in the contents of the spinal canal. This case is one of great interest, besides the point which 45 354 OUTLINE OF THE DISEASES OF NERVES. it is here introduced to illustrate. In particular, ii presents a most important example of chronic inflammation of the dura mater, affecting three distinct portions of it, and accompanied by three distinct classes of symptoms. The intense and long continued pain of the left temple, which was a prominent fea-- ture of the case at various periods, appears to have been con- nected with inflammation of a defined portion of the membrane in that situation. The remarkable affection of the functions of the seventh nerve, we may distinctly refer to the diseased condition of the same membrane where it is perforated by the nerve; and the distortion of the eye inwards, from paralysis of the abductor muscle, we trace to the sixth nerve being in- volved in the disease. No cause appears to which we can refer the paraplegia, except the disease of the tentorium, no morbid appearance having been discovered in the spinal cord or its membranes after the most careful examination. I have formerly referred to certain difficulties in the pathology of pa- raplegia, and the obscurity attending those cases in which it has been ascribed to disease within the head, from the spinal cord not having been in general examined.* Dr. Christison's Case, therefore, is one of much importance in this inquiry. The functions of the 5th nerve, as has been mentioned, ap- pear to be, to give sensation to all the parts about the face, and motion to the muscles of the jaw ; and a variety of sin- gular phenomena arise from affections of this nerve, or parti- cular branches of it. Thus, in the organs of sense, there may be loss of common sensation, without any affection of their proper senses depending upon their peculiar nerves. A young lady, mentioned by Sir Charles Bell, lost entirely sensation in the ball of the eye, without any diminution of vision; and there have been several instances Of the membrane of the nose becoming insensible to common stimuli, while the smell was little impaired. In the same manner, there may be loss of sensation in any limited part, from disease or injury of a par- ticular branch of the 5th, as in a striking case mentioned by Sir Charles Bell. A gentleman, after having a grinder very awkwardly extracted from the lower jaw, on putting a tumbler to his lips, to rinse his mouth, exclaimed, "You have given me a broken glass." He had lost entirely the sensation of * See page 222. OUTLINE OF THE DISEASES OF NERVES. 355 half the lip, from destruction of the branch of the 5th, which passes along the lower jaw, and the affection was permanent. The motion of the parts, depending on the portio dura of the 7th, of course was unimpaired.* A remarkable circumstance connected with the affections of the 5th nerve, is the tendency to inflammation and slough- ing in parts which have lost their sensibility,—particularly in the eye. A very instructive case of this kind occurred to my friend Dr. Alison. The patient had loss of common sensation on the left side of the face, the left nostril, and left side of the tongue, with insensibility of the ball of the eye, and occasion- al bloody discharge from the left nostril; and was liable to attacks of pain occasionally accompanied with fever, during which the pain was chiefly referred to the insensible parts. There were frequently attacks of inflammation of the left eye, with dimness of the cornea, which were relieved from time to time by the usual antiphlogistic means ; but at the end of two months, a line formed round the base of the cornea, which at length sloughed out, and the contents of the eye were entirely discharged. The muscles of the left side of the jaw were pa- ralytic, and felt quite flaccid when the patient chewed or clench- ed the jaws, but the motion of the muscles of the cheek was unimpaired. After the destruction of the eye, the paralytic symptoms remained stationary for a year or more; there was then a violent return of headach with fever, and death in a state of coma after an illness of a fortnight. On inspection, there was found considerable ramollissement of some of the central parts of the brain. The 5th nerve of the left side, on being traced backwards from the gangloin, was found, close to the gangloin, to be of a very dense texture, but beyond this it was much wasted, and at its junction with the tuber annulare^ nothing but the membrane seemed to remain. In another case of Dr. Alison's, there was loss of sensation of the left side of the face, followed by inflammation and sloughing of the eye-ball; after which the sensibility of the parts returned* The patient was, before the appearance of these symp- toms, and has since continued, liable to severe headach and epileptic fits. The loss of sensibility continued about six months. * Sir Charles Bell's Lectures, as reported in the Medical Gazette, vol. i. 356 OUTLINE OF THE DISEASES OF NERVES. A remarkable combination of symptoms occurred in a case related by Mr. Stanley.* There was hemiplegia of the left side, without loss of sensation in the arm and leg, but in the left side of the face both sensation and motion were entirely lost. In the left side of the tongue, sensation was lost, but motion remained. The mucous membrane of the left nostril was always of a deep red colour, and there were frequent discharges of blood from it. The conjunctiva of the left eye became deeply injected ; this was followed by opacity and ulceration of the cornea, and at last by total disorganization of the eye. There was total loss of hearing in the left ear. There were frequent attacks of erysipelas, which were entirely confined to the pa- ralytic parts of the face. The patient had been long affected with headach, and at last died two months after the commence- ment of the paralytic symptoms. A tumor was found in the left side of the tuber annulare, which compressed the origin of the 5th and 7th nerves against the base of the skull. The tumor was the size of a walnut, of a firm consistence, and brown colour, and extended into the left crus cerebelli. To affections of the nerves may probably be referred certain obscure and severe disorders of a nervous kind, some of which have supervened upon slight injuries, and others have come on without any obvious cause. A young lady, mentioned by M. Verpinet,f received a slight wound with the point of a sword on the inferior and outer part of the fore-arm. It very soon healed, but most violent pain continued in the fore-arm, wrist, and hand, accompanied by convulsive motions of the arm, and loss of the voluntary power of the wrist and fingers. The affec- tion resisted every mode of treatment for two years, and then got speedily well after the application of the actual cautery to the cicatrix of the original wound. In a lady, mentioned by Mr. Swan,! a slight wound on the thumb was followed by numb- ness, pain, convulsive motions of the arm, and spasms, which occasionally affected the opposite arm, and sometimes the whole body. In this case the affection seemed gradually to wear itself out, though she was not entirely free from uneasi- ness at the end of seven years. A very violent case of the same kind, described by Mr. Wardrop,§ was cured after twelve months by amputation of the finger. In a similar case by Larry, which followed a wound, a portion of the nerve was * Medical Gazette, vol' i. t Jour- de Med. vol. x. X Swan on Local Affections of Nerves. § Med. Chir. Trans, voi. viii. OUTLINE OF THE DISEASES OF NERVES. 357 removed, without complete success, though the disease was very much alleviated. In a singular case by Sir Everard Home,* a gentleman received a violent sprain of his thumb, by the weight of his body being thrown upon it, in saving him- self when nearly thrown off, by a sudden motion of his horse. He was afterwards liable to paroxysms, in which his thumb was first bent in towards the palm of his hand; a spasm then took place in the muscles of the arm, after which he became insensible, and continued so for about a quarter of an hour. The attacks returned frequently in the arm, but it was found that the pressure of a tourniquet prevented the insensibility. A nerve in this case was divided without success. The tour- niquet lost its effect in arresting the spasms, and he died sud- denly after three months, but there was no examination of the body. In the Medical and Physical Journal, Mr. Jeffries has de- scribed a remarkable case of a violent neuralgia of the face, which was cured by the extraction of a small fragment of china, which had been lodging, there for fourteen years ; and M. Des- cot mentions a case in which a severe affection of ten years standing was removed by the extraction of a carious tooth. A young lady, mentioned by Mr. Pearson, was seized without any obvious cause, with pain in the thumb, accompanied by a mor- bid sensibility of the part; the affection gradually spread over the arm, and was accompanied by loss of nearly the whole muscular power of the extremity, with morbid sensibility of the integuments, and a strong contraction of the fingers, so that the points of the nails were forcibly pressed against the palm of the hand. The fingers were not under the control of the will, and every attempt made to extend them was accom- panied by insupportable pain. The joint of the elbow was also contracted, and voluntary motion was nearly lost over the whole extremity. It was also very much diminished in size, while the morbid sensibility of it was inexpressibly distressing. After some time the other arm was slightly affected in the same manner, and she had likewise pain and great debility of both the lower extremities. After this affection had continued about a year, it got well under the use of a liniment com- posed of olive oil, turpentine, and sulphuric acid. This pro- duced most severe erysipelatous inflammation, which, begin- * Phil. Trans., 1801, 358 OUTLINE OF THE DISEASES OF NERVES. ning upon the affected arm, extended afterwards over the whole body.* Little has hitherto been done on this curious and interesting subject, but it certainly promises most important results, when it shall be more extensively cultivated. For we have every reason to believe, that both the nerves themselves, and the investing membrane, are liable to affections which may be the source of many obscure diseases. It is now upwards of twen- ty years since I first saw a girl, aged at that time about 18 months, and previously enjoying excellent health. She had been left for some time sitting upon damp grass, and was im- mediately seized with fever, accompanied by such a degree of oppression as led to an apprehension of an affection of the brain. These symptoms, however, passed off in a few days, and, upon her recovery from them, it was found that she was entirely paralytic in the right lower extremity. She has from that time enjoyed uninterrupted health, and is now a tall and strong young woman, but the right lower extremity has con- tinued entirely paralytic. It is also a great deal smaller than the opposite extremity, and several inches shorter. All the joints are remarkably relaxed, and the muscles flaccid; but there is no other appearance of disease in any part of it, or in the spine. Some time ago I was consulted about a young man, aged 14, who had nearly lost the muscular power of the upper part of both his arms, accompanied by a most remarka- ble diminution of substance of the principal muscles. The deltoid and biceps are reduced to the appearance of mere membranes, and the same affection extends, in rather a less degree, to the muscles upon the seapula ; the muscles upon the fore-arm, however, are full and vigorous. No disease can be discovered about the spine, and in other respects he is in perfect health. The affection has come on gradually, and cannot be traced to any cause. It is impossible, I think, to explain such cases as these, except upon the principle of local affections of nerves, which are at present involved in much obscurity. There are various other affections which ean only be referred to the same sub- ject, and which present some very singular phenomena, though the facts relating to them have not yet been brought together in any connected form. In the year 1828,1 was consulted about a * Med. Chirurg. Trans, vol. viii. OUTLINE OF THE DISEASES OF NERVES. 359 singular disease of this nature, which occurred in paroxysms, and affected in the same manner two individuals of one fa- mily, a young lady of 25, and a young man of 22. The lady described the attack in the following manner. She was first affected with blindness of the right eye, which came on gra- dually as if a cloud passed slowly over the eye; about a quarter of an hour after this, she felt a numbness of the little finger of the right hand, beginning at the point of it, and ex- tending very gradually over the whole hand and arm, produ- cing a complete loss of sensibility of the parts, but without any loss of the power of motion. The feeling of numbness then extended to the right side of the head, and from this it seemed to spread downwards towards the stomach. When it reached the side of the head, she became oppressed and partially confused, answered questions slowly and confusedly, and her speech was considerably affected; when it reached the stomach she sometimes vomited. The feeling of numb- ness then began to subside, and as it went off, she was seized with violent headach, which continued for several hours, and left her for a day or two feeble and languid. The progress of the feeling of numbness, from the little finger to the sto- mach, sometimes occupied several hours, and the common duration of the whole paroxysm was about twenty-four hours. The frequency of its occurrence varied from a few days to se- veral months ; she had been liable to it for several years, but in the intervals betwixt the attacks she enjoyed perfect health. Her brother, who was 22 years of age, was affected almost exactly in the same manner, and he had been liable to the paroxysms for many years. He was a banker's clerk, and in the intervals between the attacks, enjoyed perfect health. When he felt the commencement of the attack, he hastily brought to a conclusion any business in which he happened to be engaged,—gave distinct instructions to another of the clerks in regard to the state in which he left the affairs of his department; then walked home, went to bed, and soon after became insensible. Next day he was in his usual health, except a considerable degree of languor. These singular cases were under the care of the late Dr. Gibson of Montrose, and they seemed to derive benefit from a course of purgatives, followed by a course of sulphate of quinine, combined with small quantities of rhubarb. In a far- ther report received in 1829, Dr. Gibson informs me that the 360 OUTLINE OF THE DISEASES OF NERVES. affection had continued, but that the attacks had been less fre- quent and less severe; and that, on several occasions, they seemed to have been lessened in violence and shortened in duration by emetics. In 1834 I learnt that the young man had entirely recovered ; but that the lady had died of con- sumption in 1832, and had continued liable to occasional attacks of her peculiar headach almost to the time of her death. The affections of internal nerves present a subject of still greater difficulty, and the observations that have been made in regard to them are at- present far from being satisfactory.— Lobstein* thinks he has ascertained the existence of inflam- mation of the great sympathetic nerve ; and to this source he refers many obscure diseases, such as, violent hysterical affec- tions, sympathetic affections of the heart, spasmodic cough, colica pictonum, angina pectoris, and many obscure affections of the stomach and bowels. In the same manner, he explains the fatal effects which are produced by blows upon the sto- mach, and the severe symptoms, both in the head and in the general system, which often arise from worms, and from other disorders of the bowels. In a lady who died of urgent vomit- ing, with burning pain in the spine and in the right hypochon- drium, he found the semilunar ganglion in a state of intense inflammation, and the lower part of it livid. In a boy who died with great oppression of the chest, and distension of the epigastrium, supervening upon the retrogression of a miliary eruption, he found deep inflammation of a part of the trunk of the left intercostal nerve, and of the ninth and tenth thoracic ganglia. These speculations must be received with much caution, especially as nothing is more precarious than morbid appear- ances, consisting of mere change of colour of parts, without any of the actual results or terminations of inflammation. We must forbear to speculate where we have not facts before us, but it appears extremely probable that there are diseases of in- ternal nerves which may be the source of important morbid phenomena. Descot exposed the par vagum upon the neck of a dog, and bruised it on both sides slightly with a pair of pincers ; the wound healed favourably, but the animal was af- fected with general tremors, difficult and laborious breathing, * De Nervi Sympathetic! Fabrica, Usu, et Morbis. OUTLINE OF THE DISEASES OF NERVES. 361 vomiting, great debility and wasting. The vomiting subsided, and the other symptoms were diminished, but he had not re- covered a natural state of breathing, when he was killed at the end of three weeks. The internal organs were all healthy. The nerve on the left side, where the injury had been inflict- ed, appeared slightly increased in size, and was of a yellowish colour; and that on the right side appeared more decidedly enlarged, highly injected, and adhering to the neighbouring parts. 46 * I *• ARRANGED SELECTION OF CASES, Illustrative of the Principal Modifications of Organic Dis- eases of the Brain, intended to form a Supplement to Part III. of this Treatise.

In a case by Willis, there was a tumor three inches broad adhering to the mem- branes at the side of th^e third sinus; and in one by Saviard there was, under the junction of the lambdoidal and sagittal sutures at the broadest part of the falx, a small triangular piece of bone with very sharp angles. Where these angles came in contact with the dura mater, it was livid and dis- charged a little pus. In a lady, mentioned by Borellus, there was, near the torcular, a hard, rough, irregular mass of consist- ence, with many sharp processes and angles ; and in a case by Schenkius, there was a stony tumor like a mulberry in the brain of a man who had suffered from long-continued and in- tense headach, which left him no interval of ease day or night.

In the other cases of this class the symptoms are nearly si- milar,—fixed pain in the head and gradual loss of sight,—the intellect being frequently affected in the advanced stages, and frequently the speech impaired. A case has been already de- scribed, in which there was blindness of one eye and loss of speech, in connexion with a cyst containing albuminous mat- ter in the posterior part of the left hemisphere—(See Case XCL, page 144.) In a case by Platerus, fatal by gradual wasting, there was a tumor larger than an egg, compressing the origin of the optic nerves. In one by Drelincurtius, there was a steatomatous tumor the size of a fist between the brain and the cerebellum. In this case there were both blindness and deafness, and it was fatal suddenly by an apoplectic attack. In another, by the same writer, the pineal gland was enlarged to the size of an egg, and was of an earthy or stony structure.

Case XXVII.—A boy aged 16 months formerly healthy, was seized Vith an attack of convul- sion. It affected chiefly his right side, which was very strongly con- vulsed. He had a second attack on the evening of the same day, after which he had fever, blind- ness, and loss of the power of de- glutition. In this state he con- tinued ten days, when he had an- other fit, and after this he gradual- ly recovered his sight and degluti- tion. From this time there was a degree of paralysis of the right side, but in other respects he en- joyed good health for four years. He then had epileptic paroxysms, which at first occurred once in two months, but gradually increased in frequency. After a much longer interval than usual, a few weeks before his death, the fits returned after a fright, recurred with great frequency, and were fatal. He was then twelve years of age ; his right side had continued weak ; and at the time of his death, the On the surface of the brain, un- der the left parietal bone, there was a tumor the size of an egg, si- tuated between the pia mater and the arachnoid ; internally it was of a white and somewhat gelatinous appearance, but very firm, and when cut into, some serous fluid was discharged from it; no effu- sion.—Communicated by Dr. Beilby.

Case XXVIII.—A man aged 40, the guard of a coach, was thrown from his seat behind the coach, and received an injury of his head, by which he was confin- ed for several weeks. After his recovery he became epileptic. The fits generally occurred once in five or six weeks. After two years he fell from his seat behind the coach in one of the fits, and received va- rious injuries, of which he died in a few days. Case XXIX.—A child aged 20 months—No symptom remarked had a constant motion of the head from right to left—was pale but without fever, and did not seem to suffer. Died ematiated. Case XXX.—A woman aged 50—Epileptic for thirty years; but cough which excited acute pain under the upper part of the occipital bone. In one of the epi- leptic fits she received a violent blow on this spot, followed by con- stant pain, and after six weeks, a pulsatory tumor appeared on the spot, which could be pressed back into the cavity of the cranium, and this produced coma. After several months, she had palsy of the right arm, and both lower extremities, and soon after died. Case XXXI.—A woman of 43 —Headach ; spasmodic affections of the limbs.

Appearances. ly in one of them, six or seven weeks after she was confined to bed. It is unnecessary to detail particularly the cases of this class. They present the usual symptoms of the epileptic pa- roxysm, occurring at various intervals, and in various de- grees of severity ; sometimes accompanied by violent attacks of headach, and sometimes with little uneasiness in the head. They are sometimes fatal suddenly in one of the fits, some- times by coma. A variety of morbid appearances have been observed in such cases. Portal 'observed a remarkable indu- ration of the pons Varolii; and Sandifort found three tuber- cles in the dura mater near the sagittal suture, on the right side, and in the anterior part of the right hemisphere, a se- baceous tumor, the size of- a walnut. In a case by Lieutaud, there were seven sarcomatous tumors near the longitudinal si- nus ; and in another, a glandular tumor the size of a bean, in the substance of the right corpus striatum. In a young man, mentioned by M. Poupart, in whom the fits occurred once a week, there was a thick white substance, firmer than jelly, under the dura mater. In a man, mentioned by Lamotte, who • died of an abscess of the lungs, after having been many years epileptic, several sharp bony spiculae were found between the dura mater and the pia mater; their points being directed against the pia mater. Several cases of the same kind are referred to by Van Swieten, in one of which there was an ir- regular piece of bone in the substance of the cerebellum, an inch long and half an inch broad. In a case by Dr. Ander- son of Leith, in which epilepsy came on after a severe injury on the back of the head, the posterior part of the brain was found inflamed, and much hardened, with thickening of the membranes. A modification of epilepsy is met with, in which the convulsion is confined to one side of the body. In a case of this kind by Dr. Anderson, a portion of the brain on the opposite side was much indurated, with adhesion and thick- ening of the membranes. The same peculiarity in the symp- toms occurred in Dr. Beilby's case, mentioned in this section. In a man, mentioned by Lieutaud, the course of symptoms was somewhat different from those epileptic affections. He had violent headach for three months, then violent convul- sions, which were rapidly fatal. The longitudinal sinus, ex- ternally and internally, was covered with innumerable smaller CASES OF ORGANIC DISEASES OF THE BRAIN. 375 glandular grains, and similar bodies were found on the choroid plexus. In the fourth ventricle there appeared a tumor the size of an egg, formed by a congeries of innumerable glandu- lar bodies, verging to suppuration. Nearly the whole of the cerebellum had the same appearance. SECTION V. Fifth Class.—Symptoms in the head, with paralysis. § i.—hemiplegia. Symptoms.

The cases of this class present little variety in the symp- toms.

In a case by Bonetus, and in another exactly similar by Blancardus, there was a tumor three inches long attached to the side of the third sinus. A gentleman, mentioned by Mr. Gooch, along with a variety of nervous symptoms, had an excruciating pain of one arm, beginning at the finger ends, and gradually ascending as high as the insertion of the deltoid. The arm at last became paralytic, and soon after he died of convul- sion. Two small encysted tumors were found in the surface of the brain on the opposite side from the affected arm. In a case by Bouillaud, with partial hemiplegia of the right side of long standing, with much derangement of speech and weakness of mind, there was a tumor the size of an egg in the anterior lobe of the left hemisphere, and another smaller in the Siiddle lobe. They were internally cellular, and con- tained blood mixed with a filamentous substance, and a mat- ter resembling concrete pus. § II.—Paraplegia. Symptoms. Morbid Appearances.

I have already alluded to the uncertainty which attends cases of this class, from the circumstance of there having been in general no examination of the spinal cord; and per- haps it may still be considered as a point not absolutely as- certained, whether diseases in the brain produce paraplegia without any affection of the cord. If this does take place, it will probably be in those cases in which the disease is about the pons or medulla oblongata; though in these cases one should rather expect universal paralysis, such as occurred in Cases XXXIX. and XL., of this Supplement. From the observations recorded under the pathology of the spinal cord, it will appear that disease may frequently exist both in the brain and in the cord at the same time, and that this particu- larly is true of tubercles. In a case related by Dr. Hawkins, in the Medical and Physical Journal for 1826, there were numerous scrofulous tubercles, both in the brain and cerebel- lum of a man of 23; the symptoms had been fits resembling epilepsy, with dyeuria, partial paraplegia, and impaired speech and vision. He died after four months, having been coma- tose for three or four days before death. Had the spinal cord been examined in this case, it is very probable that tu- bercular disease would have been met with in it also. The CASES OF ORGANIC DISEASES OF THE BRAIN. 379 same observation applies to a case by Bouillaud, in which there was paraplegia with loss of speech and intellect, in connexion with a tubercular mass, the size of a turkey's egg, in the anterior part of the right hemisphere. A girl aged 14, mentioned by Lallemand, had hemiplegia of the right side, of which she recovered; four months after she had paraple- gia with loss of feeling, which extended over the abdomen and the thorax; she died in sixteen days. There was re- markable induration of a small part of the left lobe of the brain, on the outside of the ventricle, and in the vertebral canal there was extensive extravasation of blood with ramol- lissement of the cord at the seventh cervical vertebra. SECTION VI. Sixth Class.—Prominent symptoms in the digestive organs. Symptoms. Case XLI.—A medical man in the meridian of life, had been for a year liable to attacks of dyspep- sia, with headach. In October, 1815, he had severe headach with fever, relieved by bloodletting; then complete want of digestion, headach, general emaciation, and frequent vomiting, which occurred chiefly in the morning. He had various uneasy feelings, which he referred to his liver, and his com- plaints were ascribed to this source by the most eminent prac- titioners whom he consulted. In August, 1816, he had severe head- ach^ and nothing agreed with his stomach; almost every thing be- ing vomited. After some time the pam was relieved, but the. morn- ing sickness and vomiting conti- nued, with increasing emaciation, torpid bowels, frequent eructa- tions^and hiccup.

Many other cases are on record, in which the only morbid appearances were in the head, though some of the most pro- minent symptoms had been in the stomach. Some of these resemble what has been called sick headach, while others are chiefly distinguished by remarkable disturbance of the di- gestive functions. There is generally more or less headach, with various uneasy feelings in the head; but these symp- toms are sometimes not urgent, so that many of the cases have, through a great part of their progress, been referred to the digestive organs, the symptoms in the head being considered as symptomatic. A boy aged 14, mentioned by Mangetus, had loss of appetite, obfuse headach, debility and emaciation; then vomiting, with more acute headach, and he died after various intermissions. Three tumors were found in the brain, one in the situation of the corpora quadri- gemina, and two others the size of walnuts in the substance of the brain. A young man, mentioned in the Medical Ob- servations and Inquiries, vol. vi., had various complaints in the head and bowels, which were ascribed to worms. After some time he had attacks of stupor and forgetfulness, and died delirious. The only morbid appearance was ossification of no great extent in the dura mater, with appearances of in- flammation in the adjoining membranes. Similar ossification in the falx was found by Dr. Lettsom, as the only morbid ap- pearance in a gentleman who had been long affected with a train of obscure complaints, the most urgent of which were obtuse headach with frequent vomiting. (Mem. Med. Soc. CASES OF ORGANIC DISEASES OF THE BRAIN. 381 of London, vol. iii.) On the other hand, it is to be kept in mind that similar ossifications have been met with in cases in which there existed no symptoms that could be ascribed to them. This part of the subject, therefore, is involved in much obscurity. SECTION VII. Seventh Class.—Vertigo and apoplectic symptoms.—Slight and transient apoplectic attacks. Symptoms. Case XLIII.—A man aged 73 —headach with occasional attacks of giddiness, and loss of recollec- tion. He did not generally fall down, but sometimes continued walking, without knowing whither he was going; at other times the attack resembled intoxication ; his gait was feeble *nd tottering, and the attacks gradually increased in frequency and violence, though he generally recovered his recollec- tion in a very short time ; but at length, after six months, a more severe attack occurred, frftm which he did not recover; he was now confined to bed with severe head- ach, giddiness, loss of memory, and incoherence; and about the twelfth day had severe pain and partial palsy of the left leg and arm. He had then general con- vulsion, followed by perfectTiemi- plegia and coma, and died about the 23d day of his confinement.

In some we find constant uneasiness, with vertigo; in others, transient apoplectic attacks, while the patient in the intervals enjoys tolerable healthi In other cases again, there is a con- stant complaint of slight and habitual giddiness, commonly called weakness of the head, often accompanied by unsteadi- ness of the limbs. In a case of the first kind, by Zeder, he found numerous hydatids in the brain, one particularly, in the passage to the aqueduct of Silvius, and containing within it three smaller hydatids. The case which I have just referred to (Case VI.) affords a remarkable example of the other class of cases distinguished by transient apoplectic attacks; and I have quoted from Lancisi the case of a gentleman who had apoplectic attacks, connected with thickening of the mem- branes, and a polypus tumor under the frontal bone. A gentleman, mentioned by Gooch, had been for several years liable to attacks in which there was sometimes a shaking of the head, and a kind of emprosthotonos; at other times he became vertiginous, and fell down, deprived of sense for a short time. He was never entirely free from headach, and brisk exercise excited giddiness, which went off immediately upon resting. He died suddenly in convulsion, and there were found several osseous points arising from the right parietal and occipital bones, and irritating the dura mater, which was inflamed, and beginning to mortify.—(Gooch's Appendix, P\23H * To this class also Belong the cases in which, connected with organic disease of the brain, there has occurred a gra- dual loss of the mental faculties, with little complaint of pain, or any urgent symptom. In a case of this kind, which ter- minated in perfect stupidity or lethargy, Platerus found a firm, fleshy-looking tumor, the size of a moderate apple, above the corpus callosum. In a similar case, by Bouillaud, there was a steatomatous encysted tumor in the right hemisphere. FINIS. NLM032068034
