Were it not my wish to avoid as much as possible speculation, I would trace some interest- ing analogies between the small circumscribed petechias of typhus petechialis and the diffused lividity of cholera, and explain what I conceive to be the cause of this difference. I could easily have been much more minute on the subject of post mortem appearances, and had I designed to give a complete account of them, I must have necessarily been so. Before describing the treatment of cholera, I shall make a few remarks on CHOLERINE. From the slightest perceptible epidemic influence to the severest forms of cholera, there is every shade of intensity. It is consequently very difficult if not impossible, to draw accurately a line of demarcation. In general, when one or more of the essential symptoms of a fully developed case of cholera, such as vomiting, purging or cramps are wanting, or exist only in a very slight degree, the disease is termed a cholerine. Even in the absence of one of these symp- toms, should the others be exquisitely marked, and espe- cially if accompanied with considerable prostration, the disease is a decided cholera. When the peculiar decom- position of the features, the discoloration of the extremities, great refrigeration, or suspension of the urinary secretion is present in a case, it may be confidently pronounced cholera. In a cholerine however mild, the experienced eye detects in a slight degree, the epidemic impress on the features. The stage of formation of cholera, such as has been 38 described, is properly a cholerine, ready indeed to be con- verted into cholera by any accidental exciting causes. Sometimes a cholerine is ushered in suddenly, or with a slight explosion, similarly to cholera ; at other times the symptoms develop themselves gradually and successively, augmenting in severity till they are checked by remediate means, or terminate in an explosion of cholera. A brisk watery diarrhoea without tenesmus, accompanied with coldness of the feet and numbness or cramps of the extremities ; a sudden sense of weakness with nausea succeeded perhaps by vomiting ; nausea or vomiting with pains in the calves of the legs ; coldness, colicky pains with cramps : any of the foregoing combinations of symptoms always attended with depression more or less considerable of the physical and mental forces, are prominent features in common forms of cholerine. To describe every form, would require the detail of almost every possible combination of the symptoms of cholera, taken several at a time, and of various degrees of intensity. After all, cholerine is either the predisposing state of cholera, or it is the same disease in a milder degree, pro- duced by the same epidemic influence, exhibiting the same general characters, liable to put on its most aggravated form, and requiring in general a very similar treatment. I have given it a brief separate consideration, partly in com- pliance with a very general custom, and partly because it is a useful distinction in reference to treatment, and in com- paring the statistical results of different methods of treat- ment. Instead of employing more time in describing it I will subjoin some cases. (See Appendix of Cases.) 39 TREATMENT OF CHOLERA. Surrounded with treatises whose authors vaunt their suc- cess in combating this terrible scourge of our race ; in fearful anticipation of encountering it, imbued with what has been written, and decided on the treatment which he will pursue, the practitioner hears that the cholera has appeared in his neighborhood. Perhaps he is anxious to grapple with it, an opportunity is soon forced on him. His patients die in despite of his remedies, it may seem to him, before they have time to produce any effect. He has recourse to other means, and in the circle of change and experiment, to some vaunted specific medicine or method. These, so far from being crowned with success, may seem to hasten the fatal termination. Nearly every individual dies, or if here and there a single one escape, his recovery cannot be attributed to any means which may be confidently employed in the generality of cases. The practitioner is in a state of most painful indecision, yet something must be done. Perhaps he concludes that the first blow is mortal, and that nothing of much use can be done. At least, he is learning one truth, which is confessed by all practitioners in cholera of good faith, on whom experience is not thrown away, viz. that at the commencement of the epidemic, very few of those in whom the disease is fully developed, recover by any means yet known. Though I bring forward no specific, and profess to know no means which will not leave many to perish, in whom there is a complete development of cholera, yet I hope I have so improved my great and painful opportunities for observation, as to be useful to my countrymen, should this disease unfortunately appear among us,* by insisting on * See preface. 40 a recourse to medical aid in the stage of formation when this stage exists, by pointing out the means which I have found useless or prejudicial ; and by describing the remedies and treatment, which, though they leave much to be desired, are nevertheless followed by more favorable results than any other which I have known and seen employed. In the treatment of this disease, many medicines have been extolled as specifics, and by men apparently of good faith and respectable capacity. Yet one of the first facts which we learn by observation, is that the same remedies are not adapted to all cases, and that remediate agents of an opposite nature are required in the different stages of the same case. The best treatment of cholera, I adven- ture to say after extensive observation, is to fulfil the obvious indications by common medicinal means. I may go farther and add, that looking at symptoms in connection with their causes, as far as we are acquainted with the latter, the soundest treatment consists in obviating these symptoms as they rise. A large proportion of the cases in which the disease exists in its severe form, are necessarily fatal, whatever treatment be pursued. And many such cases occurred during the first period of its epidemic existence, since then especially, there were explosions without a previous stage of formation. But when the stage of formation exists, as it does in almost all cases since the first few days, I know no severe disease more certainly curable. During the prevalence of cholera, no diarrhoea or other considerable derangement of digestion should be neglected, as it may prove a precursor of the cholera in form. I believe the principal reason, why the poorer classes have furnished so disproportionate a number of victims, is to be found in their neglect of premonitory symptoms. When the stage of formation exists, it is of the last importance to have immediate recourse to medical aid, to strangle the disease in its birth. If taken at this period, 41 the cholera is certainly curable, or its explosion is prevented by timeous remedies. In this stage, which frequently con- tinues for days, an hour or half hour is sometimes of the utmost consequence. M. L. professor of chemistry at the garden of plants, had a slight cholerine of some days dura- tion ; while preparing to take some remedy, he was seized with an explosion of cholera, which was shortly fatal. Upon the occurrence of any of those symptoms which I have described as constituting the precursory stage, or ren- dering a person very liable to an attack, the patient should confine himself to the house, at least he should avoid con- siderable atmospheric vicissitudes, especially the night air — if they are at all severe, he should resort to the equable tem- perature of a bed; and in all cases, he should be restricted to a moderate regimen, avoiding the least excess in eating or drinking, and any considerable fatigue of mind or body. Slight irregularities of diet, which in common times would be harmless, may produce an explosion of the cholera. In a very great majority of cases, diarrhoea is the precursory symptom, and to this the most careful attention should be given. There is a neglect of this diarrhoea amounting al- most to a delusion, explicable partly by the fact that it is very rarely painful. It should be obviated by remaining in an atmosphere of uniform temperature, by moderate diet and opiate injections. I have not known any ill conse- quences succeed the sudden checking of the diarrhoea, by opium thus administered, as a moderate diet has been en- forced at the same time. To remove digestive derangement accompanied with vitiated secretions of the mouth, anorexia, headache, dry skin, (fee. a few grains of ipecacuanha should be administered. If a diar- rhoea accompany the preceding symptoms, it will generally disappear after the operation of the ipecacuanha. There is no danger of the vomiting producing an explosion of cholera. The state of the stomach in vomiting produced by ipecac, 42 seems to be different from that pathological state which exists in cholera. Colics, borborygmies, and nausea, with inconsiderable de- rangement of the secretions, are best relieved by mint water and paregoric with quiet and abstinence. While the epi- demic was at its height, a sensation of numbness in the calves of the legs, more or less severe at times, and occa- sionally amounting to a slight spasm, occurred almost as a solitary symptom in my own person, and in several of my acquaintances. For this, I found in my own case, relief from frictions, but chiefly from walking briskly half an hour. When the patient complains of coldness, depression of the moral and physical forces, and of the other symptoms which I mentioned in describing this stage, he should go to bed and take some warm tea, containing a few drops of paregoric ; and make use, in short, of those means with which every person is acquainted. In very many cases, simple repose and a mild diet for twenty-four or forty-eight hours, are sufficient to cause the disappearance of those indispositions and symptoms which are so often the prodromes of the disease — and which there- fore, though slight in themselves and easily removed, are not unimportant in their consequences. To arrest the diarrhoeas, which are of so frequent occur- rence during the existence of epidemic cholera, recourse is sometimes had to purgatives. These I am convinced are much less safe and efficacious than opiate injections. If a vitiated state of the secretions demands their use. we should give rhubarb and magnesia in some mint water. Saline cathartics are attended by the danger of exciting the disease they were intended to prevent. 43 TREATMENT OF THE COLD STAGE. If the precursors have been neglected, or if the disease opens by the cold stage, a new set of symptoms is ushered in, infinitely more formidable, and far more difficult to be successfully combated. On approaching the bedside of a patient, cold as marble, and pulseless, with universal and extreme prostration, ago- nized with horrid cramps, the surface of his body shrunk, and deserted as it were by the fluids, to supply the great and incessant drain of vomiting and purging, several indications present themselves to be fulfilled. The most important, indeed the essential indication of this stage, is to restore warmth and action to the surface, in other words, to establish reaction. At the same time, we must obviate those symp- toms which torture and exhaust the patient. To accomplish these ends, the patient should be put in a warm bed ; there should be administered internally a portion consisting of laudanum, mint-water, and sulphuric ether, once every hour, or at longer or shorter intervals, pro re nata. Each dose should usually contain about twelve drops of laudanum. The action of the surface should be excited, and the return of warmth solicited, by frictions made with the hand fre quently, wet with French brandy, laudanum, camphorated spirits, or something similar ; and by the applications, dur- ing the intervals between the frictions, of external warmth, by means of bottles of warm water, small sacks of warm sand, &c. Frictions, repeated from time to time, whether made as just described, or in a manner hereafter to be men- tioned, have appeared to me by far the most efficacious means of restoring warmth and action to the surface. They answer another important indication, viz. the alleviation of the cramps. To the remedies just mentioned, we should 44 add the use of opiate injections, and repeat them according to the urgency of the case. I have often conveyed currents of warm dry air, and of steam, under the bedclothes, by means of a small portable cheminee. But some caution is necessary in its use. The temperature should not be raised above blood heat. When somewhat elevated above this point, it has appeared to smother and extinguish the small remnant of vitality of the surface, which it was intended to cherish and sustain. And the more complete the refrigeration, the greater this danger apparently becomes. In this case the patient is annoyed with a sense of suffocation, and endeavors to throw off the bedclothes ; soon he is covered with a viscid perspiration, sinks into a quiet stupor, and dies in a few hours.* In de- termining the degree of heat to be applied, I believe our best guide, in general, is the sensation of the patient. When the * At first, I supposed these sinister consequences to be produced by ex- cessive excitation from the heat. The sense of suffocation experienced by the patient when his body is surrounded by this hot irrespirable air, and the refreshment he feels on exposure to the surrounding atmosphere, at a moment, too, when perhaps he complains of cold, have led me to a dif- ferent opinion. It is a fact, confirmed by numerous experiments and abundant observation, that the skin performs a vicarious function of the lungs. Any one may convince himself of the fact, by recollecting the great refreshment and alleviation of his respiration which he experiences, independently of the coolness, on baring his arms and chest, or the whole of his body, when his respiration is affected, either in a fever, or after con- siderable exertion — or when the atmosphere is very rare, as in hot weather, or suffocating, as during the prevalence of certain winds. Indeed, when- ever the respiration is embarrassed, from any cause whatever, a person seeks relief in exposing the surface of his body to the atmosphere. The physiological experiments on this point are quite conclusive, but I have not time to touch on them. Whatever be the true theoretical explanation of this subject, the fact is, that experience soon led us to renounce the practice of surrounding the patient's body with hot dry air, as well as the use of general frictions with oily liniments. 45 prostration is so considerable that he is regardless on this point, we should use the greatest caution. Such cases, how- ever, are almost always fatal, whatever we do. Still, it is an error leading sometimes to fatal consequences, to suppose that we should apply a degree of heat elevated in proportion to the refrigeration of the patient. Nothing is gained by covering the patient with many bedclothes, for there being no disengagement of animal heat, the warmth must be produced and kept up by external means. To allay the thirst, which is always very urgent, some beverage is necessary. This may be some tea, slightly aro- matic, as an infusion of camomile, the flowers of the linden tree, orange leaf water, &c. according to the taste of the pa- tient. When the sensation of heat externally is very great, lemonade, ice-cold, or small pieces of ice to be dissolved in the mouth, are very grateful. I forbear to detail a list of teas, tisans, &c. as they are known to all, and may be em- ployed according to the judgment of the physician or taste of the patient, the general indications, however, being always kept in view. In some cases an infusion of serpentaria ; in others carbonated waters would, I should suppose, be va- luable auxiliaries. As the demand for drink is frequent and importunate, and as it tends, when taken in considerable quantities, to keep up the vomiting, it should be given but little at a time. It should be warm or cold, as preferred by the patient. When the desire for cold beverages is strong, warm ones aggravate the vomiting. From ice, melted in the mouth and swallowed, I have seen no very decided effects, except the gratification of the patient's appetite. It very frequently fails to arrest the vomiting. The same means that are employed to produce reaction, are also efficacious in checking the vomiting. A composition frequently given for this double purpose, and containing the 46 articles formerly mentioned, was made according to the fol- lowing formula : No. I. fy. Sir. Cort. Aurant. Vin. Malaga Opt. Aq. Menthee aa |i. Aq. Tiliffi Europ. ^i. Etheris Sulfurici. Tinct. Opii de Rousseau aa 3i. M. When a less stimulating one was indicated we used the following effervescing mixture : No. II. J£. Aq. distillatse |iv. Aq. flor. Aurant. |ss. Sir. Gummi Arab. ^iss. Sodse Carbonas 3iss. — 3H. M. To each table spoonful of this mixture, in a little water, add one teaspoonful of lemon juice. These are formulae that have been frequently employed in the wards of 3VL Bricheteau ; and, for the sake of brevity, I shall hereafter, when I have occasion to refer to them in the cases given in the appendix, distinguish them as mixture No. I, and No. II. The proportions of some of the articles were occasionally varied to adapt them to the circumstances of the individual case. I am clearly of opinion, that in some cases, there are advantages in selecting the most efficient articles and giving them in a less bulky form. To alleviate the cramps I know nothing equal to frictions. After a very extensive use of vesicatories and sinapisms, my opinion of them is not very favorable. They interrupt the employment of frictions, and are far less efficacious than the latter. In the severest cases they do not draw ; when they do, they are painful without controlling the cramps. It is true that frictions require frequently to be repeated, but the relief afforded by them is so great, that the patient often requests them, when his prostration renders him regardless 47 of almost every thing else. To them as a powerful means of establishing reaction I have adverted above. Frictions made with highly stimulating, oily matters I have not thought, on the whole, equal to those made in k the manner and with the substances above mentioned. I have not seen any greater, nor any narcotic or antispasmodic effects from extract of hyoscyamus employed in frictions. Several trials were made of careful bandaging of the limbs, to control the cramps, but without success. To arrest the purging, to complete and sustain the reaction, a task often very difficult and requiring assiduous attention, an injection of laudanum and starch repeated pro re nata, is highly serviceable. Injections with decoctions of vegeta- ble astringents as rathania, have been employed, but they are less efficacious than those of opium. A supposed analogy in the state of the cutaneous vessels to those of a person who has been exposed to extreme cold, has led to the employment of frictions with pieces of ice. These were made with great briskness over the whole body ; and operated doubtless in some measure as frictions made with the hand or any other substance. The results of this means appear to me more favorable in some respects, than those of any other I have seen employed, especially in cases where the refrigeration was very great. In these cases no treatment could boast of much success — nevertheless, ice frictions, though a forlorn hope, offer some chances of re- covery. Certain I am, that more than any means with which I am acquainted they seem to husband and augment the small remnant of cutaneous vitality, instead of extin- guishing it as does the injudicious application of heat. I have seen the pulse at the wrist which was previously im- perceptible, develope itself during the ice frictions and for a few minutes afterwards — then disappear, again become per- ceptible on the renewal of these frictions, and after several alternations, the patient ultimately recover. Under their 48 employment the skin loses its blue tint, and becomes red and warm ; the cramps are temporarily relieved, and there follows a sense of refreshment. There is also another very important fact connected with them, viz : the stage of reac- tion which follows their successful employment, is mild and short. Ice frictions are made by one or two persons on each side of the patient, with pieces of ice as large as the fist ; with great briskness over the whole surface, particularly of the extremities, and continued from five to ten minutes. The time should be determined by the fatigue of the patient and the effect on the general and cutaneous circulation. The patient should be immediately wiped dry and placed between woollen blankets. They should be repeated about once an hour, till reaction is established. In the intervals between their employment, bottles of warm water may be applied externally. The internal remedies before mentioned, should be administered at the same time. Cold affusions I have seen employed, but have not watched their effects with sufficient attention to describe them accu- rately. The results were not such as to induce the continued use of them. The great number of patients received daily into the hos- pital, rendered the general employment of warm baths impracticable. The effects of the introduction of steam under the bedclothes, and the results of a very few trials, did not lead us to anticipate any extraordinary success from them. I can readily believe however, that in some cases, they would be found very efficacious. By means of the arm bath, rubbing the arm, and agi- tating the body of the patient, we have succeeded in many cases in obtaining several ounces of blood in this stage. For though the blood will not flow from the circulatory powers, yet having lost in agreat degree its coagulability, it is pressed out mechanically without much difficulty. From a theo- 49 retical conjecture that the organs of life were obstructed in their play by the blood dammed up in the large vessels, and from the great fatality of the disease under other treatment, this experiment of venesection was continued longer than any apparent success would otherwise have justified. Of a great many patients who were bled while cold and pulseless or nearly so, I have not seen one, in whom this operation was followed by any advantage. Indeed I know not what advantage could be rationally anticipated from abstracting a few ounces of blood from a mass unfitted in a good degree for the purposes of life, and when drawn presenting appeal ances and possessing qualities, unlike or quite the reverse of those of the sizy blood drawn in inflammatory diseases. At the moment of explosion or very soon after, when the violent derangement of the circulation and flight of the blood from the surface are commencing, while radial pulsation is still pretty strong, and before refrigeration has taken place, vene- section as a perturbator of the perturbed action, if I may so speak, may be of considerable service, as I have seen in several cases. In these cases, the pulse was full, and in general neither hard nor frequent ; though each pulsation was made with a kind of hurried excitement. An attendant was attacked in the hospital with vomiting, purging, cramps in the calves of his legs, and a sensation of immense weight upon the praxordia, simultaneously. His pulse was full, not frequent, rather agitated. Coldness of the extremities commencing ; surface of the body other- wise warm. He was immediately bled twelve ounces ; fifteen leeches were applied to the epigastrium, which were followed by the alleviation of the weight on the prsecordia. The internal remedies already mentioned were given, frictions and warmth were applied externally. Refrigeration in this way was prevented ; the action of the heart and arteries sustained, and the particular symptoms obviated. 7 50 The patient was subsequently bled a second time twelve ounces, and recovered without any adverse symptom. When, however, the circulation is noticeably more feeble than in health, or refrigeration prevails to any great extent, as happens in all cases shortly after the attack, if they are neglected, venesection is prejudicial. Sinapisms and blisters, which have been considerably employed in this stage, I have found of but little efficacy in controlling the cramps. — As external excitants to prevent re- frigeration, and subsequently when the system is making fee- ble efforts at reaction, sinapisms applied so as not to interfere with the use of frictions, and only long enough to redden the skin, are of service. A sense of oppression and weight about the praxordia is mitigated by stimulating poultices, made of linseed and mustard, powdered and moistened with aq. ammonise. Excitation along the spine I have produced in various ways and in different degrees without any benefit. Galvanism I have seen employed at first with the appearance of some benefit, but its use was soon renounced. Ipecacuanha, while the coldness and prostration are great, the vomiting urgent, and before any attempt of the system is made at reaction, is rejected in the course of the vomiting without any perceptible effect. The precious moments immediately succeeding the explosion, I should be very unwilling to waste in the tardy operation of ipeca- cuanha. When reaction is imperfectly developed, and the patient is passing from one to the other, or struggling between the two stages, a dose of ipecacuanha opportunely administered arouses the powers of the system as it would seem by concussion, and enables the patient to clear the limits of the cold stage, and enter those of reaction. Punch so highly commended by M. Majendie, I have not seen employed, as all the advantages that could be expected 51 from this kind of remedy, we obtained with the mixture before mentioned and good Malaga wine. Charcoal was administered in several cases, but with effects so unimportant as not to lead us to persevere in its use. Individual recoveries are pompously announced of persons who have breathed some of the gases, as oxygen, and nitrous oxyde go,ses. But the success of their patrons has not yet been so great as to lead to their employment by practitioners, who, though extremely anxious to discover a method of curing the cholera, are not pledged to patronize any exclusive treatment. I have not yet seen saline injections into the veins employed. It appears from the result of some experiments made in Paris, as well as statements received from London, that the shout of victory has been prematurely raised. Nor do I perceive the necessity of this method of medication, since absorption, though less active in the cold stage than in health, is still performed. Camphor, cajeput oil, and the host of specifics, I will dispatch with remarking the fact, that they have not sustained a use of forty-eight hours, in the hands of those who profit by experience. In summing up the treatment of the cold stage, we find that the leading indication is to establish reaction, that, as this takes place, the vomiting, purging and cramps are gradually diminished or entirely subside ; that these ends are effected, not by any single medicine, or exclusive method of treatment, but by common remediate means, selected and employed according to the intensity of the symptoms, and adapted to the circumstances of each case individually considered. The leading points of treatment, I will adventure to repeat, in order to present them under a single coup oVceil. The patient on being taken should be immediately put to bed, warm applications made externally, frictions frequently 52 and briskly made, twelve or fifteen drops of laudanum, with some oil or water of mint, administered in some warm brandy or generous wine, and repeated pro re nata ; injections containing from twenty to sixty drops of laudanum should also be administered and repeated if necessary ; as a beverage, some mild aromatic tea, in small quantities, and warm or cold to suit the taste of the patients. If unfortunately the patient has become quite cold, caution is required in the application of heat, or this may be replaced by ice frictions. If the patient is seen immediately after the invasion, and the pulse be full, pretty strong, and somewhat excited, as I have seen it in a small number of cases, he should be bled. When by these means varied according to circumstances, the pulse becomes perceptible or fuller, the surface gradually warm and losing its discoloration, and the other symptoms are diminishing or disappearing ; our reme- dies should be modified, gradually diminished or withdrawn. The difficult point in the treatment of cholera is the pro- ducing of a complete and free reaction. When this is fully developed, though the state of the patient is attended with danger of life, and requires a very careful and timeous ad- ministration of remedies, we may in general pronounce him recoverable. When the treatment which I have detailed is put vigor- ously into execution, at the commencement of this stage, before the patient becomes cold and the circulation greatly enfeebled, we may anticipate a favorable issue of a large proportion of cases. But when the refrigeration is complete, and that assemblage of symptoms exists, which I have at- tempted faintly but faithfully to describe, I am most fully persuaded, that human means are inadequate to the restora- tion of many of the patients. Many hours even, before they are moribund, there does not remain sufficient vitality to produce reaction ; or, if this is forced for a few minutes, the common play of the functions soon exhausts the small share of excitability that is left. 53 I have insisted from time to time in the course of my remarks on the great, and to a considerable extent, unavoid- able mortality of cholera, because it is a. fact, and my object is to relate facts ; because authors in vaunting remedies and methods of treatment, lead us to anticipate results, which it is certain they themselves never obtained ; and, because I wish as much as in me lies to urge the necessity of employ- ing remedies, the moment any choleric symptom shall pre- sent itself, during the prevalence of this epidemic. TREATMENT OF THE STAGE OF REACTION. In the treatment to be pursued during reaction, it is ne- cessary to bear in mind the different forms or degrees of reaction into which I divided this stage when speaking of its symptomatology. As it is being developed, we should diminish or discontinue the remedies employed in the second stage, carefully watching its progress, doing nothing while it appears to proceed and be sustained by the powers of the system, cautiously aiding these powers if they are insuffi- cient, and ready to interpose if it becomes excessive. In this manner by judiciously refraining from injurious inter- ference, or by delicately directing nature in her operations, the skilful practitioner conducts his patient to a favorable termination of the disease ; while the meddlesome charlatan hurries on his to a catastrophe, under the delusion that severe diseases require at all times heroic remedies. Not unfrequently when judiciously managed, the reaction continues to augment to the balance of health and then to cease ; leaving the patient feeble but with no adverse symp- tom, in the manner heretofore described. In this case, he should remain a few days in bed, very slowly and gradually 54 returning to his usual diet. For three or four days he should take in moderate quantities, light animal broths. He should carefully avoid any exposure, or any fatigue of mind or body. The great liability to a relapse renders these precautions very necessary. Even slight irregularity or excess in diet endangers a relapse. In some cases, as I have before mentioned, the powers of the system are so prostrated or oppressed, that reaction is imperfectly developed ; the surface is not completely warmed, especially the feet ; the vomitings, though much abated in frequency and severity, occur from time to time, and generally consist of a bright green, or of bilious matter ; the cramps have not entirely disappeared ; there is more or less mental torpor ; the system seems struggling under a load too great for its energies. This state of imperfect reac- tion is, in short, a continuation, in many of its symptoms, of the preceding cold stage, and it requires the same treatment, modified according to the urgency of the existing symptoms. In this state, particularly where there is much precordial oppression, ipecacuanha is highly serviceable ; it produces a general salutary shock and excitation, frees the large ves- sels of the blood dammed up in them, and increases capillary and cutaneous action. After its operation the vomiting is diminished or entirely ceases. To sustain the good effects of the ipecacuanha, and to allay the vomiting where it still persists, we should employ something similar to the mixture ture No. II. page 46. When a more stimulating one is thought necessary, we may substitute in its place No. I. of the same page. For tenderness of the epigastrium, which is a pretty frequent symptom in this state, we may ap- ply leeches or blisters. This tenderness of the epigastrium should not prevent us from employing the mild stimulating treatment demanded by the condition of the patient in other respects. As excitants, or as derivatives, when there is much 55 mental torpor, or tenderness of the epigastrium, blisters are very serviceable. They should be applied to the insides of the legs, and when intended for excitants, removed before vesication has taken place. After what I have said on the treatment of particular symptoms in the preceding stage, I do not conceive it necessary to dwell on this point at the present time. As the patient approaches convalescence,, or the development of a more perfect reaction, he should be treated in the careful manner before described. When the reaction is full and complete, we have often only to moderate its force by diluent drinks, and leave the patients, for the most part, to the efforts of nature. In other cases, grave local affections, or general states of the system, are to be obviated. The danger most to be feared is the supervention of a cerebral affection, one, two, three, or four days after the development of free though moderate reac- tion, manifested at first by drowsiness, redness of the face, and injection of the conjunctiva. The pulse is generally pretty full, though neither hard nor frequent. It is often accompanied by several severe typhoid symptoms. What constituted the most difficult feature in the treatment of this cerebral affection, was its obstinate recurrence, after having been several times obviated. Patients could not sustain the repeated loss of blood necessary when venesection was relied on to remove it. Consequently it was usually fatal in the early period of the epidemic. We afterwards used a remedy, the results of which have been more flattering than any other I have known employed against any symptom what- ever of cholera. This was a bladder of ice applied to the head. It was refreshing to the patient, admitted of fre- quent reapplication without exhausting his strength, and was effectual to the removing of the affection. The fre- quent and obstinate return of this affection, in whatever way it might have been combated, rendered the ice an 56 invaluable remedy. Six or eight leeches were generally applied behind each ear, and appeared to be valuable coadju- tors-. We have frequently practised general bleeding against affections of the head and stomach, in this state, with appa- rent temporary advantage, certainly without marked injury ; nevertheless, my observation has not led me to be very pro- digal of blood in cholera. In some few cases, there is a frank and decided inflammatory state of the system, with a full, strong pulse, rendering venesection necessary. Derivative blisters to the calves of the legs seemed also beneficial. They were accompanied with few inconveniences, for I saw no tendency to gangrene in any stage of the disease. But it was the ice to which the patient attributed his relief. Under its influence the stupor declined, and, at the same time, the dryness of the mouth, the heat of the surface, and the sordes on the teeth autd lips, when it existed, disappeared also. The ice, contained in a bladder, was applied to the fore and upper part of the head. When its use for a longer period than two hours of the twenty-four was judged neces- sary, an interval of two hours was permitted to elapse be- tween the successive applications. The tenderness of the epigastrium, which was of frequent occurrence, easily yielded to the application of a few leeches, and the quiet and abstinence which the patient observed. In some few cases, however, venesection was judged neces- sary. Towards the favorable termination of this stage, there occasionally appeared a slight cough, rarely so severe as to require more than the usual mild regimen, with some diluent and mucilaginous drinks. As a beverage in this stage we may give gum water, lemonade or carbonated water — or something that shall fulfil at the same time some indication that may exist. If the heat of the patient is great, the lemonade, &c. may be ice cold. A return of the purging which was not unfrequent, I some- 5? times suspected to be occasioned by considerable quantities of cold lemonade taken into the stomach ; but of this I am not sure. The purging when it recurs, should be immedi- ately arrested by laudanum injections ; for it does not relieve the local congestions or inflammations if any happen to exist, but endangers a return of the state of collapse. The suppression of urine, which often continues for some days after the full development of reaction, not giving the patient any uneasiness, nor being in any way an urgent symptom ; and its return though of very favorable au- gury, rarely producing any marked crisis, was seldom attempted to be obviated by any means specially directed to this object. In one case, where the urine had been sup- pressed many days, it speedily reappeared on the use of nitric ether. In several other cases I have thought that this remedy hastened its reappearance.
