COMPOUND PANCREATIC TABLETS. (FAIRCHILD.) Especially useful in Intestinal Indigestion. W.e have been led to offer this combination, which has been for some time employed with good results in extempora- neous prescriptions, because it seems to be a well-advised asso- ciation of remedies. The pure Extractum Pancreatis is here combined with Bismuth—highly valued as a,sedative in allaying the irritabil- ity of the alimentary tract frequently associated with dyspep- sia, and with Ipecac, which, in small doses, is the mo.-t admir- able stimulant of the digestive functions. Each tablet contains : Extractum Pancreatis, - - - gr. 2. Bismuth Subnitrate, Squibb’s, - gr. 2. Powd. Ipecac, gr. 1-10. One or two tablets for a dose, an hour or so after eating.

THE MODERN TREATMENT OF Diseases of the Liver, PROF. DUJARDIN-BEAUMETZ, -BY- Member of the Academy of Medicine and of the Council of Hygiene and Salubrity of the Seine: Editor of the Bulletin General de Therafieutique, Paris, France. translated from the fifth french edition by E. P. HURD, M. D., Newhuryport, Mass. 1888. GEORGE S. DAVIS. DETROIT, MICH. Copyrighted by GEORGE S. DAVIS, 1888 AUTHOR’S PREFACE. Dr. Hurd, who in making known my works in the United States, has displayed a zeal and activity which I cannot too much praise, in this volume presents to the medical profession of the American Republic that part of the second volume of my Lecons de Clinique Therapeutique which pertains to the treat- ment of diseases of the liver. The hepatic diseases constitute an important chapter of internal pathology, and one which I have here endeavored succinctly to treat, epitomizing to my best ability the existing knowledge respecdng this subject. I am aware that I have not given to this chapter all the extension and development which it deserves, and this is my reason: Utility being my main object, I have taken up only those diseases of the hepatic gland which we observe in our country, leaving one side all that important group of liver diseases which are so prevalent in tropical countries, and which the reader will find described at great length in leading text-books devoted to this subject. I may venture to hope that physicians in the United States will accord to this volume the same welcome and the same indulgence which have been extended to my previous publications. In concluding, I have to thank Mr. George S. Davis for the pains which he has taken in the typographical execution of these little volumes (for with the present I include the two volumes of last year’s series on Diseases of the Heart), and I have especially to acknowledge my obligations to my friend and correspondent, Dr. Hurd, for the fidelity with which he has reproduced my lectures, preserving their original form, and making no more changes than the English idiom demands.

Clinical Therapeutics (1885) (from the press of G. S. Davis, Detroit). An octavo of about 500 pages, compre- hending the treatment of Nervous Diseases, General Diseases and Fevers. This is Vol. 11l of the Lesons de Clinique Ther- apeutique. 2. On Bacteria (1885). This treatise, of about 100 pages, was published as an appendix to “ Diseases of the Lungs of a Specific Character,” by Germain See, and issued by Wm. Wood & Co., as the November number of the Library Series for 1885. 3. Diseases of the Stomach and Intestines. This work, which is the second part of Vol. I, of the the Lemons de Clinique The'rapeutique, is an octavo of about 400 pages, and constitutes the May number of Wood’s Library Series for 1886. 4. New Medications. This is a volume of 320 pages, and is a part of Davis’ Leisure Library Series for 1886. 5. Alimentary Hygiene. A treatise on the Dietetic Treatment of Disease. The various chapters of this work may be found in files of the Boston Medical and Surgical Journal, Medical News and Therapeutic Gazette (the latter principally) for the years 1886-1887. 6. The Modern Treatment of Diseases of the Heart. 7. The Modern Treatment of Diseases of the Aorta. These two volumes comprise the remainder of Vol. I of the Lemons de Clinique Therapeutique, and constitute Nos. 2 and 4 of the Leisure Library Series for 1887. 8. Hygienic Therapeutics. This work, which treats of Massage, Exercise, Hydrotherapy, Aerotherapy and Climato- therapy, has been published in its entirety in the columns of the Therapeutic Gazette, 1887-1888. VIII From the above statement, it will be seen that all of the Lemons de Clinique Therapeutique, a work which has had no little popularity and success in France, has now been rendered into English, except Vol. 11, which is devoted to the treatment of Diseases of the Liver Kidneys and Lungs. The present volume comprises Diseases of the Liver, and the succeeding volume on Diseases of the Kidneys, will leave only about half of Vol. II of the Leqons untranslated. I hardly need to apologize for the omission of many pages of the bibliographical indications. Some abridgement was deemed necessary, and it seemed that these references, pertaining, for the most part, to works in foreign languages, might better be spared than any other part It is unnecessary that I should call attention to the practical character of this work, and the wealth of research which it em- bodies, or allude to the prominent position which Dujardin- Beaumetz now occupies in the estimation of his colleagues in the medical profession everywhere, as a leader in therapeutics.

Gentlemen:—I intend to devote the present course of lectures to the therapeutics of diseases of the liver and kidneys, diseases which are frequent and often demand active treatment. I will begin with the study of affections of the liver, but before entering upon the main part of my subject, I desire to set forth in this lecture certain general considera- tions on the liver from a therapeutic point of view. You know the importance which I place on an exact knowledge of the anatomy and physiology of the organ whose diseased condition claims your in- tervention; such knowledge is the indispensable basis of a rational and scientific treatment; I will therefore sum up briefly what we know respecting this organ. I shall be brief on the anatomy of the liver, as you are already familiar with this subject through the works of Kiernan, Hering, and especially of Prof. Charcot. You know the ordinary description of the hepatic lobule, which Kiernan has compared to an oak-leaf, whose petiole and mid rib represent the interlobular vein, while the lateral branches, formed by vessels and cellular tissue, constitute a frame work in which are lodged the hepatic cells discovered by Purkinje and Henle.* You also know the regular, almost geometric, disposition of the hepatic cells, and the con- stitution of these cells, which contain pigmentary granulations, and nuclei with roundish nucleoli. * The hepatic lobule is constituted by a group of cells around which are blood vessels, bile ducts, lymphatic lacunae, and connective tissue fibrillse. Grouped together, these cells form little five or six faced prismatic masses, whose base rests on branches of the hepatic vein (sub-lobular vein). In the centre of the lobule is seen a small vein (intra-lobular vein); each lobule is enveloped by a sheath from the capsule of Glis- son which supports the ramifications of the vena portae (inter- lobular veins), which, according to Hering’s comparison, unite in the interlobular spaces after the manner of a tree which plunges its roots into the interstices of a rocky soil; these veins are accompanied by arterioles from the hepatic artery, bile ducts and lymphatics. The hepatic cell has an average diameter of from i - 19 /J. (Kolliker), (Henle and Kolliker); it has one or more nuclei of 9[l in diameter, which are provided with a nucleolus. Some of the cells have even as many as from three to five nuclei (Henle). The contents of the cells consist, Ist, of pigmentary 3 The web which contains the cells is constituted by a connective tissue framework, which, when affected by hyperplasia, gives rise to true cirrhosis; then by blood vessels, lymphatics and bile ducts, forming a multiple capillary net-work surrounding each of the cells. I must call your attention to the interlobular spaces, upon which Kiernan has rightly placed so much stress, and which Sabourin, in his researches on the constitution of the hepatic gland, has consid- ered as the biliary lobule.* These spaces are, in fact, the seat and starting point of abscesses, of tubercles, of syphilomata and of lymphomata of the liver. Alcoholic cirrhosis, a dis- ease which you see so frequently in our wards, and to granulations; 2d, of granules with pale borders, which have not the reaction of fat and which mostly fill the cell; 3d, gran- ules with dark borders, shiny, giving with ether and osmic acid the reaction of fat. Charcot, to whom we are indebted for these notions respecting the cell, remarks that these fat gran- ules are to a certain extent found in the animal and in man in a multitude of physicial conditions, such as lactation and di- gestion. * The interlobular spaces are formed by the polygonal space which several lobules leave between them; they contain branches of the portal vein and hepatic artery, bile ducts, and lymphatics; all send ramifications between the neighboring lobules, and all the elements are surrounded by Glisson’s cap- sule. This is according to Kiernan’s description. Sabourin has since modified slightly the anatomical and. which 1 shall return when the subject of its treatment comes up, has for origin these same spaces, being due to a perivascular inflammation affecting the ramifica- tions of the vena portse, as has been well shown by the researches of Solowief and Charcot. 4 If the anatomy of the liver has made manifest progress the past few years, and seems to-day almost complete, it is necessary to bear in mind that the knowledge of the physiology of this organ has not kept pace with that of the anatomy, and there are still certain functions of the liver concerning which physi- ologists are not completely agreed. Nothing, perhaps, in the history of medicine is more interesting than a general survey of the en- deavors which have been made to find out the func- tions of the liver. For centuries the world accepted with unques- tioning faith the doctrine of Galen, who taught that the hepatic gland was the centre of animal heat and the organ which presided over sanguification. Then came the discovery of the bile in the 17th century, and so to speak, classical conception of the liver. He considers the hepatic gland as constituted by tubular elements. He takes, as the centre of the biliary lobule, the portal interspace, into which abut the pyramidal segments formed by the hepatic lobules just as they have been heretofore described. This ag- gregate constitutes a glandular territory, perfectly limited, to which he gives the name of biliary lobule. (Sabourin, Soc. de Biol., 17 December, 1881). 5 all the old doctrines were lost sight of, and the liver was reduced to the simple office of an emunctory, designed to separate from the economy an excrementitious liquid, the bile. But modern experimental physiology was destined to restore to the organ the high functions which were assigned to it by Galen and his school. In fact, it is, as you know, in the liver, in the hepatic cell itself, that Claude Bernard places the glycogenic function. The same organ also, according to Mur- chison, Brouardel, and Charcot, is the seat of that physiological process which is the most manifest expression of the combustions of the economy, namely, the production of urea. Lastly, a great num- ber of physiologists are of accord in affirming the haematopoietic functions of this gland. As you see, the liver has regained in our day its former high importance. From a therapeutic point of view, the study of the functions of the liver is, it must be admitted, much more limited ; we have really observed only the action of certain substances on the biliary secretion, and are ignorant of the action of medicaments on the liver as a glycogenic organ. As for the liver considered as a producer of urea, physiologists are far from being fully agreed. To the labors of Murchison and of Brouardel have been op- posed other experiments and other researches, and in particular those of De Sinety and Martin, which go to show that perhaps too much has been affirmed as to the relation of the liver to urea-formation, and that this excrementitious principle has not for its exclusive seat of production the hepatic gland, but that it is formed in all the glands and all the tissues of the economy. 6 De Sinety has observed that in frogs, which survive for some time the total ablation of the liver, the urine continues to contain urea. This doctrine of the formation of urea in the liver is one of the most contested in physiology; two orders of proofs have been alleged in substantiation, physiological and pathological. (a),' Meissner, Kuhn, Lehmann, have shown that while the muscles contain no urea, the liver contains notable quanti- ties. Cyon has shown, moreover, that in too cubic centimeters of blood which has not yet passed through the liver, there exists 0.09 of urea, while there is present 0.14 of urea in the same blood after haviug traversed that organ. Gathgens and Hensius have maintained that albumin- ous matters in the liver break up into glycogen and urea. (b). From a pathological point of view, Murchison, Charcot, Brouardel have seen that in diseases of the liver, which destroy more or less completely this organ, the quantity of urea notably diminishes. Hence Brouardel has concluded that the quantity of urea formed and eliminated in the 24 hours is dependent on two principal influences: 1. The state of integrity or alteration of the hepatic cells; 2. The greater or less activity of the hepatic circulation. Murchison has gone even farther, and maintained that the liver even fabricates uric acid. But to these facts have been objected other experiments and other analyses, and in particular those of De Sinety and Martin before alluded to, which tend to invalidate this teaching. Physiologists have 7 laid stress upon the preponderant role of alimentation, as the quantity of urea varies according to the food ingested; and the more probable view would seem to be that urea is not formed exclusively in the liver, but throughout the entire organism. But there is one point in this study which ought to detain us longer: I allude to the passage of medi- cinal substances through the liver after having been introduced by the digestive tube, and their more or less prolonged sojourn in this gland. This is one of the most interesting subjects connected with the physiology of the liver, and you will see that by virtue of the experiments of Lussana, Heger, Schiff and Jacques, we may derive therefrom fruitful therapeutic results. You are aware that for a long time physiologists have known the possibility of the accumulation of cer- tain toxic substances in the liver, and it is a rule in legal medicine in cases of poisoning to analyze the liver, in order to find there traces of arsenic, copper, lead and other substances which have been suspected of determining symptoms of poisoning. Paganuzzi, of Padua, was the first to show the difference which exists in the mode of elimination when certain salts of iron are introduced by the veins of the general circulation, and when they are intro- duced by the mesenteric veins; in the first case the salt is eliminated by the kidneys, in the second by the bile.* * Annuschat has made some interesting experiments on the elimination of lead by the bile in lead poisoning. He has 8 Lussana, basing himself on some previous experi- ments of Schiff, since verified by Rosenkranz, re- searches which have shown that the bile secreted in the intestine returns to the liver to be eliminated anew, verified the experiment of Paganuzzi, and affirmed as the result thereof that the reconstituent and haemato- poietic effects of ferruginous preparations are due to the intimate action on the hepatic cells of the salts of iron, which, when introduced by the digestive tube into the liver, are then eliminated by the bile and pass back again into the liver by the entero-hepatic circulation described by Schiff. In 1873, Hegar, of Brussels, applying to the elu- cidation of this question Ludwig’s ingenious method of artificial circulations effected in isolated organs, discovered that when blood containing a large dose of nicotine is made to pass through the hepatic gland, this alkaloid disappears completely in the liver, so that you no longer find any trace of it in the hepatic veins. In 1877, Schiff discovered that not only does nicotine in passing through the liver lose its toxic pro- perties, but that other alkaloids are almost as com- pletely destroyed by this gland, and he mentions among the latter hyoscyamin. Lastly, in 1880, Victor Jacques, a Belgian physi- cian, completed these researches by showing that a shown that in animals the greater the ingestion of lead the more abundant its elimination by the bile, and that the lead in he intestine comes in large part from the biliary secretion. 9 certain number of alkaloids introduced by the diges- tive passage sojourn a while in the liver, and that some are in part destroyed in the hepatic gland, and that others may be eliminated after a limited time, whether by the bile or lymphatics. What is the intimate action of these substances on the hepatic cell ? Are more or less stable com- binations formed with these alkaloids, which either destroy the properties of the latter, or which, being slowly dissociated by an excess of albumen, are thereupon eliminated anew? We do not know, but it is none the less certain that these researches enable us to explain facts heretofore very obscure. Among these facts is the marked difference which exists between the effects of medicaments, and in par- ticular of alkaloids, when introduced by the mouth and when administered by the hypodermic method. The prompt and energetic action of subcutaneous in- jections finds an easy explanation. The medicine passes immediately into the general circulation, and brings its therapeutic or toxic action to bear upon different parts of the economy. When introduced by the mouth, however, the alkaloid passes into the liver, and there it is in part destroyed or tardily eliminated by the hepatic gland, hence we see the superior ad- vantage of hypodermic injections, which render every day such marked service; and we can never be too grateful to Wood, of England, and to my very regretted Master, Behier, for having introduced and popularized this method. This complete destruction or tardy elimination of alkaloids by the hepatic gland gives ns a physiologi- cal explanation of two other orders of facts: (i) the innocuousness of certain poisons introduced by the mouth, such as curare, of which Claude Bernard has shown the absolute inefficacy when absorbed by the alimentary canal, and (2) phenomenon so frequent- ly observed when certain alkaloids are given by the mouth, and in particular the alkaloids of the solanacege—l refer to the tardy effect of these alka- loids, and what Gubler has described under the name of “accumulation of doses.” You are acquainted with all these facts; you know that when we give atropine or duboisin in very minute doses, and for several days in succession, we are in danger of seeing symptoms of poisoning set in, although the daily dose remains the same. To-day, by virtue of the experiments which I have just men- tioned, we have a clear and scientific explanation of these facts. The alkaloid is absorbed by the digestive tube and fixes itself in the liver. Then, at a variable time, it is eliminated into the intestine with the bile, or passes into the circulation with the lymphatics, and its presence goes to augment the portion which is absorbed into the general circulation of the daily doses which you have administered. Permit me to add a word: I have just told you that medicaments introduced under the skin and pass- ing directly into the general circulation are eliminated by the kidneys. I shall show you, as we go on, that if this elimination is wanting, the therapeutic effects of the alkaloid cease, and give place to toxic symp- toms. It would be important to study, as opportunity may occur, the influence of diseases of the liver, and in particular of those which completely destroy the hepatic cell such as cirrhosis, on the action of alka- loids introduced by the mouth. Here there is an im- portant series of researches to be made, to which I invite your attention. But this action of the hepatic gland does not per- tain exclusively to the vegetable alkaloids, but also, and equally, to the toxic alkaloids which we have seen to be incessantly produced in the economy. In my work on Diseases of the Stomach and In- testines, I showed you the important part which these ptomaines or leucomaines play in the economy, and I dwelt on their, elimination by the different emunc- tories. The liver has an important function in the elim- ination and destruction of these toxic products. Hence, when its parenchyma is altered, you can under- stand how these toxic substances may accumulate in the blood and produce their deleterious effects, effects which play a preponderant role in the symptoms which accompany destruction of the hepatic gland. This discovery of the morbid poisons which the economy produces during life, and the important part 12 which the liver plays in such cases, justifies somewhat the view set forth by Lautenbach* several years ago. The liver is the organ that secretes the bile, and from this point of view it possesses for us a great therapeutic interest, for there are numerous substances which modify the biliary secretion; these are called cholagogues. But before setting forth the physio- logical experiments which demonstrate this action, I shall make a few remarks concerning the bile and its secretion in the normal state. Considered in the most general manner, bile is constituted of three elements, cholesterine, bile pig- ment, biliary acids and salts, f Cholesterine, which the researches of Berthelot * Lautenbach basing himself on the experiments of Schiff, maintained that the liver not only destroys poisons intro- duced into the economy but that the organism in the physio- logical stage produces a poison which is destroyed by the liver as fast as it is generated. (Phil’a Med. Times, May 20, 1887.) f According to Charles Robin the composition of the bile is as follows: Water, 915.90—819.90 Chloride of Sodium, 2.77 to 3.50 Phosphate of Lime, i.ooto 2.50 “ “ Potassium, 0.75 to 1.50 “ Lime, 0.50 to 1.35 “ “ Magnesia, 0.45 to 0.80 Salts of Iron, 0.15 to 0.30 “ Magnesia, traces to 0.12 Silica, 0.30 to 0.66 Taurocholate of Sodium, 56.50 to 106.60 Glycocholate or Chplate of Sodium, traces. Leucin, Tyrosin, Urea, traces. Cholesterine, 1.60 to 2.66 Lecithin, 1 Margarin, Olein and 3,20 to 31.00 traces of Fat, Biliverdin, 14.00 to 30.00 Mucosin, traces. have caused to be classed among the monatomic al- cohols, is a fatty substance which presents itself to the microscope under the form of rhomboidal tablets. You know also that these crystals have a characteristic reaction which consists in the red coloration which they assume in contact with sulphuric acid. To-day everyone is agreed in adopting the theory of Flint as to the origin of this substance, and Vulpian in his re- markable “ Lessons on the Bile ” has accepted this view which regards cholesterine as a product of dis- assimilation of the nervous substance. Feltz and Ritter have shown, on the other hand, that this sub- stance when it accumulates in the blood does not pro- duce any grave toxic symptoms.* Trefanowski has attained similar results, finding in a thousand parts of bile from the gall bladder of a human sub- ject, 908.70 of water, 91.22 of fixed matters, of which 28.56 were glycocholates and taurocholates. * Cholesterine (C26H44 G-|-H2 O)discovered by Poullet and De la Salle in biliary calculi then by Fourcroy in a desiccated liver, was studied by Chevreul in 1824, who gave it the name which it bears to-day. It is a non-saponifiable fat, white, crystallizable, insoluble in water, soluble in soap and water, ether, wood spirit, boiling alcohol, glacial acetic acid, and in solutions of taurocholic acid and taurocholates; it con- tains almost eighty-four per cent, of carbon and twelve per cent, of hydrogen; the crystals present themselves under the form of rhomboidal plates, which are thin and brilliant and fuse at 140° C. Cholesterine is met in divers regions of the organism. As for the bile pigment, bilirubin, it is an azotized non-albuminous principle derived from the decompo- sition of the coloring matters of the globules, whose properties Tarchanoff and Vossius have thoroughly studied; in fact, from a chemical point of view, there is a great similarity between haematin and bilirubin, and you will see when we come to take up the subject of jaundice that the possible transformation of the former into the latter has given a name to a special form of jaundice, hsematogenous jaundice (icterus sanguinis). We shall see, also, that bilirubin has a characteristic reaction, and that the most important and best known is that determined by nitrous nitric acid, which in contact with bilirubin gives a play of colors; red, green, blue, yellow and brown.* and in the blood; it is very abundant in the nervous centres, existing in greatest quantity in the white substance. Since the researches of Austin Flint, 1868 (“ Experimental Researches on a New Function of the Liver ”), the majority of physiologists have regarded cholesterine as a product of dis- assimiiation eliminated by the liver and passing into the intestine with the bile. Beneke stands alone in regarding it as a product of the hepatic secretion contributing to the resorp- tion of the fats in the intestine. *Bilirubin, an azotized non-albuminous principle, pre- sents itself under the form of a red amorphous powder, or of needle-shaped crystals; it is held in solution by the biliary acids. There are two tests in common use: Gmelin’s and Schwanda’s. Gmelin’s test, which is also the common test for But the truly essential part of the bile consists in the biliary salts, glycocholates and taurocholates of sodium. You know that these two acids easily break up, the one into cholic and cholalic acids, the other into taurin and glycocol. Pettenkoffer has given a means of readily detecting these acids. If you sub- ject them to contact with a mixture of sulphuric acid and sugar, you see them take on a beautiful violet purple color. These acids give their principal character to the hzematoidin, is the nitrous nitric acid, which, instilled drop by drop into a solution containing bilirubin, gives a play of colors; green, blue, violet, red and brown. When hsematoidin pre- dominates, the violet color is the most pronounced, while the green color is the most marked when bilirubin predominates. Schwanda’s test is acetic acid, which when heated with biliru- bin, gives a green color. Bilirubin and hsematoidin are very much alike; they differ principally in this respect, that in hsematoidin an atom of iron replaces the two atoms of hydrogen which exist in the mole- cule of bilirubin. There are other biliary pigments which seem to be derivatives of bilirubin, such as biliverdin, bilifulvin, bili- fuscin, biliprasin and bilihomin. Studeler has given to bili- rubin the formula; Cl 6 HlB N03. He regards biliverdin as bilirubin plus water and oxygen. Vossius has made some recent experiments on the biliary secretion, and on the quantity of coloring matters secreted in 24 hours. He has shown that in a dog weighing 25 kilo- grammes, the quantity of bile varies from 60 to 150 cubic cent- imetres in 12 hours, and that the coloring matter of the bile varies between 0.0487 and 0.056; the average furnished by biliary secretion, and in fact, while we have seen that cholesterine originates in processes of disassimilation of the cerebro-spinal axis, and the coloring matter of the bile has for its origin the hsematin of the blood globules, the biliary salts are formed solely in the liver, and are a product of the secretion of this gland. This is, you must remember, a fact of capital import- ance, which clearly differentiates the kidney from the liver, and while the one does nothing but separate from the economy substances which have accumulated in the blood, the other produces from elements in the blood special substances which are characteristic of eight experiments’was 0.056. This richness in coloring mat- ters is little modified by food; it nevertheless augments when the animal is subjected to a regimen exclusively hydro-carbon- aceous. When considerable quantities of haemoglobin are in- jected into the blood, the coloring matter of the bile is not aug- mented. On the other hand, when you inject distilled water into the veins, or a 5 per cent, solution of sodium chloride, you augment in a notable manner the coloring matter, and the same thing takes place when you introduce coloring matter into the blood. This shows, as Tarchanoff has pointed out, that the liver has the property of separating from the blood the col- oring matter of the bile, to incorporate it with its proper secretion. To test the coloring matter in the urine, Rosenbach pro- poses the following process; The urine is passed through white filtering paper, and when the filter is dry, a drop of nitric acid is let fall upon it, and then several concentric zones show themselves; green, blue, violet and yellow. The glycocholates and taurocholates of soda are obtained its secretion. The experiments of Muller, Lehmann, Kund, and especially the beautiful experiment of Molesschott, who performed ablation of the liver in frogs, and did not find the biliary acids to accumulate in the blood, are absolutely demonstrative on this point. Where is the bile elaborated? Must we admit, as Charles Robin suggests, that it is in the glands of under a crystalline form. They form from 55 to 61 per cent, of the solid residue of the bile. Their acids are glycocholic or cholic acid discovered in 1825 by Tiedmann and Gmelin, and taurocholic or cholalic acid. Glychocolic acid (Cl 6 His NOg) is but little soluble in water and ether, more soluble in alcohol. It is obtained under the form of fine needles. Under the influence of hydrochloric acid it breaks up into cholalic acid and gly cocol (sugar of gelatin). Cholalic acid, obtained for the first time by Demarquay, presents itself in the amorphous state or in four-sided prisms with bevelled edges. By the action of prolonged heat it is converted into dyslysin. Moreover, dilute sulphuric or hydro- chloric acid transform it at first into choloidic acid, then into dyslysin. Taurocholic acid (C 36 H45 N04 S.) has not yet been ob tained in a crystalline stale. Under the influence of heat and of caustic alkalies, it breaks up into cholalic acid and into taurin. Taurin, discovered by Gmelin, crystallizes in 4 or 6 sided prisms, terminated by pyramids with four facets. It contains sulphur in considerable proportions. Like glycocholic acid, taurocholic acid exercises a right handed polarization. the bile ducts that the secretion of the biliary acids takes place, while to the hepatic cell is reserved the glycogenic function? Must we locate in the hepatic cell itself this secretion? This is a question which the researches of Kolliker seem to have solved, for he found the biliary acids in the hepatic cells. It is, then, in the cell that the secretion of bile takes place, and it remains for us to study what are the influences which cause this secretion to vary. In the physiological state, the bile, as Colin has shown, flows continuously into the intestine, but this flow is subject to intermittences; for example, during the period of digestion, and under the influences of certain emotions, the secretion is much augmented. We shall study more at length the various modifica- tions in the biliary secretion in a future lecture devoted to biliary lithiasis. The quantity of bile secreted in twenty-four hours in a dog weighing ten kilogrammes is 150 grammes (Nasse and Plater). In the cat, according to Stackman, the quantity secreted per kilogramme of the weight of the animal is sixteen grammes in the twenty-four hours. This proportion is the same as that found by Scott & Ritter; thus a man of average weight, say 150 pounds, will secrete one kilogramme, or about two pounds of bile in twenty- four hours. This figure is, however, higher than that furnished by direct experiments on patients with biliary fistulae. De Witch and Westphalen, in two cases of the kind, the one a man, the other a woman, noted that the quantity of bile secreted in twenty-four hours was about 500 grammes. You know that when we tie the hepatic artery, we do not cause the secretion of bile to cease. It is the same when the ligature embraces the portal vein, leaving the artery intact. What do such experiments show ? They prove this, that owing to the numerous anastomoses, it suffices that the hepatic shall be sup- plied with blood, it matters not from what source, in order to accomplish its function of secretion. This is so true, that when you bleed animals, you see the secretion of bile notably diminish; on the other hand, if you make an intra-venous injection of water, the biliary secretion is augmented. But there is a physiological process which notably augments this secretion, viz.; digestion, or, more strictly speaking, the irritation produced by food or chyme on the intestinal mucosa. There is in these cases a double action: first, an augmentation in the production of bile, then augmentation of the excretion caused by increase of the contractile movements, of which the gall bladder and its ducts are the seat. In this regard, there is a fact noticed by Rohrig and Vulpian which presents a great interest, viz.: that when you inject water into the intestine of animals under experimentation, you see the secretion of the bile augment.* * Numerous experimenters have investigated the mode of secretion of bile. Malpighi, Schiff, and others, found that after ligature of the hepatic artery, the biliary secretion still went on. Ore, of Bordeaux, by numerous experiments on As for the influence of the nervous system on this secretion, it is not at all doubtful; at the same time, experiments in this direction are not very decisive. Certainly, the vaso-motor nerves—vaso-constrictors and vaso-dilators—undergo there, as everywhere else, modifications from reflex influence, but, as I have said before, we need more light on this subject. 20 Such, gentlemen, are the brief considerations which I wished to present respecting the liver and its cats and dogs, also noticed that the secretion continued after obliteration of the vena portae, on condition, however, that the obliteration was not made suddenly. Schiff undertook several series of researches. In a first series he tied the branches of the coeliac axis and the inferior diaphragmatic artery. In a second series of experiments, he tied the portal vein and the small branches going to the liver; he separated the hepatic artery and tied in one mass the hepatico-duodenal ligament and the common bile duct; the animals died in convulsions an hour and a half after the operation. Finally, in his third series of experiments Schiff gradually interrupted the circulation of the portal vein, and observed that the biliary secretion per- sisted. To explain this fact, Schiff says that the secretion con- tinues by reason of persistence of the portal circulation, due to the accessory para-umbilical portal veins. With regard to the influence of the nervous system on the biliary secretion, numerous experiments have been made by Heidenhain, Rohrig, Munk and others. Heidenhain in operating on dogs, has shown that electrization of the spinal cord produces, first, an augmenta- tion then retardation, in the secretion of bile. He thinks that the retardation of the flow of bile is a consequence of the con- functions. Now that we know the general particulars of its anatomy and physiology, and the conditions which preside over the secretion of the bile, we can study the action of certain substances on this secre- tion, and pass in review that important group of medicaments which have so important a part in the treatment of diseases of the liver; I refer to chola- gogues, which will be the subiect of my next lecture. 21 striction of the vessels and diminution of the blood pressure in the interior of the liver. The acceleration of the flow of bile, on the contrary, is to be attributed to contraction of the bile ducts. Munk has arrived at the same conclusions as Heiden- hain. As for Rohrig, he has also observed the augmentation of the biliary secretion under electrization of the cord. But electrization of the central end of the sciatic nerve does not, he says, produce this augmentation of the secretion, as Heiden- hain and Monk have affirmed. Vulpian, moreover, remarked that section of the pneumo- gastrics and experimental lesions of the floor of the fourth ventricle produce a congestion of the liver with increased ac- tivity of the biliary secretion. These facts have, he thinks, a high importance. They explain the mechanism of the jaundice resulting from strong mental emotions, such as fear, anger, etc. CHAPTER 11.

Gentlemen:—When I was lecturing on purga- tives, I told you that there were certain of them which act by augmenting the secretion of bile. It is to this group that the name of cholagogues has been given. I told you, also, that I was intending to study more at length this class of purgatives when I came to dis- eases of the liver, and the subject properly comes up for consideration to day. But before enumerating the different substances which enter into this group, I will first examine upon what experimental bases the study of cholagogues rests. Formerly it was by examination of the stools that physicians were enabled to classify these medicaments, and according as the stools were more or less bilious, the medicine was considered as having a greater or less action on the liver and was reckoned cholagogue. This method, which was not a very scientific one, has given place to more precise researches, for which we are principally indebted to certain foreign physi- cians.* In 1863 Hanfield Jones was the first to enter on this experimental method. He gave certain medicinal substances to animals which he afterwards killed, and he then examined the state of the liver and intestines; according as he found the hepatic gland more or less congested, he concluded that the medicament had a more or less energetic action on the biliary secretion. This it must be admitted, was a somewhat rude and primitive process, which had been nevertheless put in usage by previous experimenters and in particular by Pecholierf in studying the action of calomel. In 1867 and ’6B, the British Association, which has done so much to elucidate important problems in therapeutics, and in particular, that of the action of alexipharmic medicines and of antagonism in thera- peutics, submitted the question of cholagogues for discussion, and appointed a commission consisting of Arthur Gamgee and Hughes Bennett to undertake a series of experiments to ascertain the action of the so- called cholagogues. This commission made an important report, based * Arthur Gamger, Rutherford, Hughes Bennett, Rohrig, etc. f Pechc lier (“ Indications for the Employment of Calomel in the Treatment of Dysentery”) noticed in 1865 that in hares to which he had administered calomel, the liver was very much congested. on numerous experiments performed upon dogs, which were all put on the same diet and subjected to the action of certain medicaments whose influence on the biliary secretion was then studied by careful anal- ysis. In 1873, Rohrig, in Germany, completed and per- fected this mode of research. He curarized dogs and subjected them to artificial respiration. Then, after taking care to empty the gall bladder and tie the cystic duct, he introduced into the extremity of the common bile duct a tube ending in a tapering point, like a dropping tube; then, by the aid of a metronome beating seconds, he counted the number of drops of bile flowing in a given time by the tube, and thus studied the action of different sub- stances introduced into the stomach or digestive tube of animals under experimentation. You see that quite an improvement was effected in the way of scientific definiteness, as indicated by the distance which separtes the method of Jones from that of Rohrig; but progress did not stop here. Rutherford and Yignal, in 1875, repeated and improved the processes of Rohrig; they proceeded at first as did the latter experimenter, that is to say, they curarized the animal, emptied the gall bladder, and applied a ligature to the cystic duct but instead of intro- ducing into the common bile duct a simple tapering tube, they employed a glass pipette adapted to a rubber tube, terminated at its distal extremity by another glass tube dipping into a graduated test measure; then they calculated the quantity of bile secreted in a given space of time. In some preliminary researches, these experi- ments proved first of all that curare has no action on the biliary secretion, and that during the entire dura- tion of the experiment the bile kept its composition almost unchanged; then they showed that in the nor- mal state in the dog the quantity of bile secreted is about 20 cu. c. m. per kilogramme of the weight of the body and per hour, and it is by relying on this latter figure that they established the coefficient of cholagogue medicaments. This word coefficient, then, indicates the quantity of bile secreted in an hour and corresponding to i kilogramme of the weight of the animal; the more that figure exceeds the sum of 20 cu. c. m., the greater the action of the medicament on the biliary secretion. Note in this connection that the substance under experimentation was not intro- duced by the mouth, but inserted into the duodenum; it is in this way that Rutherford and Vignal have arrived at the following table which I here place be- fore you: 26 COEFFICIENTS EXPRESSING THE ABSOLUTE QUANTITY OF BILE OBTAINED IN EACH EXPERIMENT DURING ONE HOUR PER KILOGRAMME OF THE WEIGHT OF THE ANIMAL.

This group has in great part well stood the test of experimentation; podo- phyllin still holds in the tables of some of the experi- menters the very first place among the cholagogues.* But the action of podophyllin is characterized by this curious fact, to which I shall again allude, viz., that its maximum effect, as far as the activity of the biliary secretion is concerned, does not take place with large, but with moderate doses. Aloes and rhubarb remain still good cholagogues, while the drastics properly so-called, colocynth, scammony and croton oil are very moderate cholagogues. Thus far, you see, experimentation has done com- plete justice to the medicaments called cholagogues, but this is not the case when we take up the study of calomel, and we have here, it must be confessed, one * The experiments of Rohrig, on the one hand, and of Rutherford and Vienal on the other, do not agree respecting the action of these cholagogues on the biliary secretion, as may be seen by the following classification: CHOLAGOGUES IN THEIR ORDER OF EXCELLENCE. According to Rohrig: Colocynth, Jalap, Aloes, Senna, Rhubarb. CHOLAGOGUES IN THEIR ORDER OF EXCELLENCE. According to Rutherford and Vignal: Podophyllin. Rhubarb, Aloes, Colchicum, Senna. of the most delicate and difficult points connected with the question, and one which shows how difficult it often is to bring into harmony physiological experi- menters and clinicians. From the time of Paracelsus and Von Helmont down to our days, physicians have vaunted the action of calomel on the liver; the green stools produced by this medicament were considered an undoubted sign of the elective action of calomel on the hepatic gland; and whatever Stille may have said to the contrary, who affirmed that the color of the stools produced by calomel were due to a subsulphuret of mercury, it is to-day demonstrated by the experiments of Golding Bird and Simon, and especially by the researches of Michea, that this coloration is due to a biliary pigment. If clinical experience is unanimous in affirming the cholagogue action of calomel, quite as decided agreement and unanimity exist among experimental physiologists in denying this action. Consult the ex- periments of Scott, Hosier, Kolliker, Midler, of Ben- net, of Rohrig and of Rutherford, and all will tell you that calomel does not augment the secretion of bile in the dog but that it diminishes it. How are we going to reconcile results so contra- dictory. Some authorities, and in particular Fraser, have attempted an explanation; the experimenters, they say, put themselves in special conditions which were different from what one observes in the man whether well or sick. Between the curarized dog living by artificial respiration and the man, there is a great difference. But this argument seems to me to miss the point, and for this reason: if it were sound we ought to reject in toto all the experiments on cholagogues. for the same objection applies to all the experiments, which would thereby be hopelessly viti- ated. But this none of the authorities are willing to grant, and there is general agreement that the re- sults of the experiments as far as most of the medica- ments are concerned are trustworthy, and valid. Murchison seems nearer the truth when he says that mercury augments the biliary excretion without augmenting the secretion; i. e. by exciting the contractions of the bile ducts, by diminishing the catarrhal congestion of these ducts, by modify- ing perhaps the bile itself, calomel causes a greater quantity of bile to flow into the intestine without, however, augmenting the secretion of this liquid. I am inclined to take the same view of the case as Murchison, and, while giving the precedence to clinical experience over physiological experimentation, I persist in regarding calomel as one of the best cholagogues; but I would associate with it another mercurial preparation, which some have supposed to be void of cholagogue properties, namely, corrosive sublimate. In fact, while the mild chloride of mer- cury, when administered experimentally, diminishes rather than augments the biliary secretion, the cor- rosive chloride, on the contrary, according to Ruther- ford, augments this secretion; therefore, I advise you, when you wish to obtain the full benefit of the salts of mercury in the treatment of hepatic affections, to com- bine calomel with corrosive sublimate, and to prescribe pills containing ten centigrams of calomel and two milligrams of the sublimate. These pills, in the dose of one or two at bedtime, have a marked cholagogue effect. As you see, the group of cholagogues, with the exception of calomel, passes, as it were, intact through the hands of the experimenters. To this group should be joined ipecac, whose particular action on the liver you have already learned theoretically. For you can- not have forgotten what I said while on the treatment of dysentery, when I endeavored to explain the heroic curative action of this medicament by the excitation which it produces on the biliary secretion. This view is confirmed by experimentation, and you see by the work of Rutherford that ipecac deserves a place among the best cholagogues. But the researches of the English experimenters have not had merely for result to confirm what tradi- tion had taught us concerning the cholagogues, but also to call attention to a new group of medicaments of whose action on the biliary secretion we were abso- lutely ignorant. These are certain new medicaments which I am going to pass in review, and which I shall classify under two heads; those derived from the vegetable kingdom and those from the mineral. The first of these groups, by far the most im- portant, is composed of a series of substances called by the English writers baptism, euonymin, hydrastin, iridin, juglandin, leptandrin, phytolaccin. These are aqueous or hydro-alcoholic extracts of uncertain chem- ical composition, and which, if they are to take a place in therapeutics, need to be studied anew. Their very name, even, cannot be accepted in France, at least where their very termination is suggestive of alkaloids or glucosides, and it will not do again to commit the mistake which Bonjean has perpetuated, to the con- fusion of therapeutic nomenclature, by giving to the hydro-alcoholic extract of ergot the name of ergotin. I propose, however, on this occasion to employ the terms in ordinary use, as, in fact, is done in the case of podophyllin, and to say baptisin, euonymin, etc. This terminology, moreover, is adhered to despite the fact that chemists have already described under the names of juglandin, euonymin, iridin, hydrastin, cer- tain substances which are veritable alkaloids. One of my pupils, Dr. Daret, has made a careful study of these new cholagogues, the first, in fact, that has been undertaken in France.* I here place before you samples of several com- paratively new pharmaceutical products which I have obtained in England, and of which I am enabled to *G. Daret on Certain New Cholagogues of Vegetable Origin (These de Paris, 1880). give you a summary description, owing to the kind- ness of my excellent interne in pharmacy, M. Jaillet, who has examined them. Here is a sample of euonymin. It is, as you see, a greenish powder, of strong, rank odor, insoluble in water, slightly soluble in alcohol and ether, and which is obtained from a species of wahoo, the euonymus atro-purpureus, much prized in our gardens by reason of the beautiful color of its leaves. It is an oleo-resin, which burns readily, and which must not be con- founded with the euonymirie, a species of mannite, studied by Kubel, Roedei'er, and Grunner. The latter is a crystalline substance, obtained from the enonymus Europseus. In France euonymin is often found under the form of a brown powder; the difference in color is owing to the part of the plant from which the resin has been extracted. In England the leaves and stalk are utilized; in France the root. This substance, which, according to experimenters is one of our best cholagogues, and which has received honorable mention in the U. S. Dispensatory, is given in the dose of ten to twenty centigrammes (two to four grains). You do not obtain from it a very decided purgative action, but its cholagogue effect is quite marked. I have myself prescribed it with success in cases of catarrhal icterus, and in dys- entery. Moreover, in France Henri Gueneau de Mussy, who was the first to introduce these medica- merits, has derived good effects from it, and Dr. Blondeau has reported a case of pseudo-membranous enteritis in which euonymin produced excellent results. The euonymus is chiefly known in the U. S. under the name of wahoo, a name given it by the Indians. The plant has also been named spindle tree and burning bush. It is a tall, erect shrub, with small dark-purple flowers, in cymes, in axillary peduncles. The wahoo is indigenous in the northern and western states. Euonymin in this country is obtained from the dried bark by reducing it to powder, agitating with chloroform a tincture made with dilute alcohol, separating the chloroformic solution, and allowing it to evap- orate, and by a further process of purification; the euonymin thus obtained is uncrystallizable, and intensely bitter. Dr. Geo. B. Wood speaks of it as tonic, hydragogue, cathartic, antiperiodic and cholagogue, although he regards its action as somewhat uncertain. A fluid extract is much used; dose, a dessert to a tablespoon- ful. The euonymus is a favorite with the eclectics.—[Trans.] This blackish powder with shiny particles is iridin, an oleo-resin extracted from iris versicolor. Wood and Bache mention it, and Rutherford ranks it along with euonymin among the very best chola- gogues. It has given me the same results as euony- min, and from a therapeutic view I regard it as of about equal merit. Iris versicolor (blue flag) is found in all parts of the U. S. in low wet places and on the borders of swamps, which it adorns by its large and beautiful flowers. The root is the medicinal part. Blue flag possesses cathartic, emetic, diuretic and chola- gogue properties. It is, however, little used by the profession at large. The dose of the dried root is from ten to twelve grains. “ Under the unscientific name of iridin or irisin, which should be reserved for the active principle when discovered, the eclectics have obtained an oleoresin, got by precipitating the tincture of the root with water and mixing the result with some absorbent powder, such as licorice root. This may be given in the form of a pill in the dose of three or four grains. It is thought to unite cholagogue and diuretic with aperient proper- ties.”—[Wood and Bache.] This yellowish powder, which I now show you, with strong and rank odor resembling podophylihn, is baptism, which is extracted from the wild indigo, Bap- tisia tinctoria; it is a medicament similar to the pre- ceding, and the dose, according to Wood and Bache, is 2 grains at bed time. The Baptisia tinctoria is an indigenous plant found all over the United States, abounding in woods and uplands. The whole plant becomes black when dried, and has been used for dyeing purposes, known by the name of “dyers’ weed.” The root, which is the medicinal part most in use, has a nauseous, bitter and somewhat acrid taste. Baptisin, which is an impure extract, is emetic and cathartic in large doses, laxative in small doses. Rutherford has experimented with it in dogs in the dose of six or seven grains: it produces considerable congestion of the stomach and intestines. I here show you a specimen of hydrastin, the alcoholic extract of Hydrastis Canadensis, which you must not confound with the crystallized hydrastin, which is a real alkaloid, discovered by Durand, and studied by Perrins and Mahla. It is a decided cholagogue, and more of a purgative than the pre- ceding preparation. This, by the way, is one of the most curious facts connected with the experiment of Rutherford, i. e., the discovery of these non-purgative cholagogues which augment the biliary secretion with- out increasing the number of stools, and in the em- ployment of which it is necessary to add a true purga- tive, such as sulphate of soda, for instance. Hydrastin is a resinous alcoholic extract of the root of hydrastis Canadensis. It presents itself under the form of a brown powder, of bitter and astringent taste. It is soluble in alcohol and in ether, little soluble in water, soluble in chloroform. This gum-resin readily burns, and gives all the characters of a resin. It is probable that the alkaloid dis- covered in 1861 in the same plant by Durand is contained in this gum-resin. Durand’s hydrastin (hydrastia W. and B.) which has been studied by Perrin and Mahla, crystallizes in white spiny prisms and melts at 1350 C. (2750 F.) Heated on platinum foil, it burns with a sooty flame. It is insoluble in water, soluble in alcohol, ether, and dilute mineral acids. Hydrastin is associated with berberine in the roots of the hydrastis Canadensis. This specimen of juglandin which I here place before you under the form of a black powder has a special oily odor resembling that of decayed nuts; as its name indicates, it is an extract of the Juglans cinerea and belongs to the group above mentioned, being a cholagogue medicament without being a purgative. A propos of this substance, I must remind you that Tanret has found in the butternut an alka- loid which he has called juglandin, and that Luton has recommended in the treatment of tuberculous menin- gitis an alcoholic extract of the juglans under the name of extract of Granval.* [Podophyllum peltatum (described in “ Diseases of the Stomach and Intestines) is a perennial plant of the Berberidaceas family, growing in North America. The parts employed are the rhizomes and roots, from which a resin is extracted called podophyllin, which presents itself under the aspect of a brilliant powder of yellowish brown color, and acrid, bitter taste. According to Mayer, besides this resin, podophyl- lin contains berberine, a colorless alkaloid, a special acid, an odorous matter and saponine. The resin is soluble in alcohol, ether, the essential oils, bisulph- ide of carbon, and in part in the alkalies. In the dose of from }i to i grain, podophyllin provokes regular stools ten to twelve hours after its administration. Large doses (i to 2 grains) are likely to produce nausea and vomiting as well as colic.] This powder with shiny particles which I here place before you is leptandrin, an impure resinoid extract of the Leptandria veronica. Reeb, of Phals- bourg has recommended it along with podophyllin in *Tanret’s juglandin is in the form of long needles; this sub- stance exists in the leaves of the butternut combined with tan- nin. The juglandin of commerce is an alcoholic extract of the butternut, and comes in the form of little lumps of a brownish color; dose, 2 to 5 grains. the treatment of dysentery, and Lloyd has made a special study of this resin.* Here is a sample of sanguinarin, an impure ex- tract from the Sanguinaria Canadensis. We are al- ready acquainted with an alkaloid derived from this same plant, Sanguinarine. The product now before you is a cholagogue with but slight purgative proper- ties. According to Rutherford, it excites the secretion of the liver, giving rise to a flow of watery bile; the dose is from one-half grain to a grain. Lastly, this powder, of a dirty grey, earthy color and saltish taste, is phytolaccin, a resin which is ob- tained from a plant which grows in abundance in North America, the Phytolacca decandra. It will not do to confound this product with the phytolaccine studied by Claassen, which is a glucoside; the pre- * Lloyd, American Journal of Pharmacy, 1880. Leptandrin is of rank nauseous odor, bitter somewhat sweetish but nauseous taste. According to Lloyd, Mayne and Mayer, the resin precipitated from the alcoholic extract of the Leptandria, does not contain the active principle of this plant to this must be added the precipitate thrown down by sulphuric acid from the liquid which has furnished the resin; this precipitate contains an impure glucocide. Reeb, a pharmacist of Phalsbourg, made a study of leptandrin in 1875. According to him, this substance has feeble laxative properties, in large doses producing frequent evacuations. He has employed it in conjunction with pod- ophyllin in epidemic dysentery; it may also be given, he says, in this disease associated with camphor and quinine. paration before you, in large doses, is both purgative and emetic, while in smaller doses (one to three grains) it is both cholagogue and purgative. What is the true value of these substances with which Rutherford, according to the expression of Gueneau de Mussy, has enriched the armamentarium of the physician ? What is to be their future ? The first trials which I have made in Cochin hospital with these substances, obtained directly from Edinburgh, have shown that, with the exception of euonymin, hy- drastin, and perhaps iridin and phytolaccin, there is little to expect from these novelties, and that they are largely impure, ill-defined substances, demanding both from a chemical and pharmaceutical point of view, a more complete investigation. To these complex products, these oleo resins, I would join two well-defined medicinal agents which seem to possess great activity as cholagogues: Col- chicine, which, according to Garrod, has a marked action on the liver, and aconitine, which, also as Laborde and Gelle have shown, also acts powerfully on the biliary secretion. Colchicine is an extract of the colchicum autumnaie, it is crystalline, inodorous, with sharp bitter taste, soluble in water, alcohol and ether. There is also an amorphous colchicine, which is neutral and uncrystallizable, not forming definite salts, and breaking up, under the influence of acids, into colchiceine and a resin- ous substance. Tannate of colchicine has been extolled as remedial in gout. Garrod employs only the amorphous colchicine. The dose would be two to four milligrammes in water or in some aromatic infusion. As for the cholagogues of mineral origin, I shall rapidly pass in review the new facts brought to light by the experiments of Rutherford. These experi- ments have taught us that salicylate of sodium is a powerful excitant of the biliary secretion, and it occu- pies the third rank in the scale of cholagogues. According to Rutherford, the action of sodium salicylate on the intestine is very feeble, hence, when given with chola- gogue intent, the dose should be administered at bedtime, and, followed the next morning by a dose of Glauber’s salts. The phosphate and especially the sulphate of sodium are also excellent cholagogues, and thus is explained the favorable action of certain sodic sul- phate mineral waters, and especially of Carlsbad, on hepatic affections. The double tartrate of potassium and sodium, Rochelle salts (sal de Seignette), is also a good cholagogue. But while the salts of sodium augment the biliary secretion, those of magnesium on the contrary, and especially the sulphate of magnesia, diminish this secretion, according to the experiments of Rutherford. We ought then, if we accept this experimental datum, to substitute as a purgative in affections of the liver sulphate of sodium for sulphate of magnesium. We have already seen the contradictions which exist between clinical and physiological experimenta- tion in reference to the action of calomel; there is the same want of agreement relative to the action of the alkaline carbonates on the biliary secretion. Clinical experimentation in almost numberless in- stances says that the alkaline carbonates, and in particu- lar the sodic carbonate waters, such as Vichy, have a curative action in affections of the liver, and physio- logical experimentation replies that instead of increas- ing the secretion of bile, they diminish it. We admit the claims of the experimental physiologist without discarding the results of the clinic. Doubtless the secretion of bile is not augmented, but the alkalies, in modifying the functions of nutrition, in regulating the digestive functions, in calming all inflammatory states of the disordered mucosa, in acting on the circulation of the liver and modifying the bile, have certainly a manifest action on the excretion of the bile, and on the hepatic gland. Moreover, if experimentation shows us that the alkalies have no action on the liver as the organ of the biliary secretion, recent experimental researches con- ducted by Martin Damourette and Hyades* have put in clear light the undoubted action of alkalies on the augmentation of the figure of urea secreted in the twenty-four hours, and for this reason their beneficial effect on the liver considered as the principal organ of urea formation, f *Acad. des Sciences, March, 1880. “On the Nutritive Effects of Alkalies in Large Doses.” f Martin Damourette and Hyades have shown the As you see, from the point of view of the treat- ment of diseases of the liver, it is not sufficient that experimentation shall have pronounced more or less definitely on a medicament, to warrant the medical profession in at once adopting these conclusions as a datum of practice; it is necessary that clinical experi- ence shall confirm the results of experimentation, and I cannot point you to a more striking proof of this than the facts which I have just stated relative to cholagogues. How are we to explain the cholagogue action of the substances which we have just examined ? We may suppose it to be due to the irritation determined by these substances on the duodenum, and thus com- pare what takes place in the liver with what takes place in the salivary glands when you irritate the buc- cal cavity. At the same time this explanation does not seem sufficient, and for this reason: we have seen undoubted effects of alkalies, and in particular of the natural alkaline waters, on nutrition. According to them, these alka- lies are trophic agents in quantities equal to a bottle of Vichy water per day. They energize nutrition in helping the entire series of acts which constitute it, and they notably increase the figure of the blood globules and favor disas- similation, as is proved by the augmentation of urea and diminution of uric acid in the urine. Alkalies are then pro- moters of disassimilation (nutritifs dbperditeurs) after the manner of muscular exercise, hydrotherapy and inhalations of oxygen. that there are substances which are cholagogue with- out being purgative, and vice versa. Rutherford, on the other hand, has shown that the more a substance is purgative the less it is chola- gogue; thus it is that purgatives which are the highest in the scale, drastics for instance, are medicines which diminish rather than increase the biliary secretion. Can we affirm that it is by acting on the circula- tion of the liver that the special effect of these medi- caments is produced, and that every medicament which has for its property to congest this organ should be ranked in the group of cholagogues? This explana- tion hardly meets the requirement, for we have seen that certain cholagogues really lessen the circulation in the liver. We are, in fact, reduced to the supposi- tion that it is by acting directly on the hepatic cells, or on the secretory nerves which preside over the function of the organ, that the substances act which we have just passed in review. In order that you may better remember what I have just said, I here place before you a couple of tables which I have borrowed from Gueneau de Mussy, tables in which are grouped the different medicaments according to their cholagogue power. The figure which accompanies each substance is its biliary co- efficient, i. e., the quantity of bile obtained per hour and per kilogramme of the animal weight.

Gentlemen:—Biliary lithiasis is a frequent affec- tion which gives rise, as you know, to certain acute symptoms known under the name of hepatic colic, for which a prompt and energetic treatment is demanded; therefore I shall make this subject a part of my present course, and dwell at some length upon it. But, in order that you may well understand the value and utility of the therapeutic agents recommended in such cases, I must enter somewhat into anatomical and physiological details concerning the bile ducts and the biliary calculi which pass through them. I shall be brief in my description of the bile ducts. You remember the course of the hepatic duct, which takes its origin in the liver by that network of biliary canaliculi, which, as we have seen in one of the pre- ceding lectures, surrounds the hepatic cells. After a short transit, this duct meets the cystic duct from the gall bladder, and both unite into one duct, the ductus choledochus, and empty into the duodenum by the ampulla of Vater. I shall say little concerning the bile duct, with whose anatomy you are sufficiently familiar; but there is one point to which I desire especially to call your attention, viz: the intimate structure of these bile ducts. As for the mucous membrane, there is general agreement among anatomists; it presents little valves or folds, especially in the neighborhood of the cystic duct, which are called valves of Heister; moreover, this mucosa has glands in greater or less abundauce. There is not the same agreement respecting the fibro- muscular structure of these ducts, and in some experi- ments undertaken about fifteen years ago, I was led to make an attentive study of this question.* I had been impressed by the disagreements of histologists on this point. In fact, while certain an- atomists, as Sappey, assign to these excretory bile ducts a muscular coating rich in unstriped fibres, and Fort even describes as pertaining to this coat three layers with variable directions, others, on the contrary, * Dujardin-Beaumetz, “A Study of Spasm of the Bile Ducts.”—(Bull de Therap., 1873.) as Kolliker, Leydig, Frey, and Virchow, affirm that there is not any muscular layer properly so-called in these ducts; they scarcely even admit that any exist even in the gall bladder. In order to decide this contention, I prevailed upon two histologists whom I have the honor to have had for pupils, Prof. Renaut, of Lyons, and Prof. Grancher, to study anew this question. The results of their labors were decisive; both show that there un- doubtedly exist smooth muscular fibres in the bile ducts, and that these muscular fibres are disseminated throughout the fasciculi of connective and elastic tissue constituting the fibrous coat of these ducts; moreover, they put in clear light this fact, already long known, that inflammation taking place in the duct augments this muscular layer; Bouisson, Herard, De- ville, and Broca, have, in fact, shown that in patholo- gical cases this stratum may become hypertrophied.* * Below the epithelium you find a very thin layer with a small number of oval nuclei scattered throughout its substance, a layer, essentially of connective tissue fibres, and very adher- ent to the subjacent tissue; this tissue,which forms the limiting membrane of the ductus choledochus, is remarkable for its rich- ness in fine elastic fibres thickly set in a connective tissue very poor in cells. In proportion as your dissection embraces the deeper tissues of the choledochus, the elastic connective tissue changes, and the reciprocal disposition of these elements is modified; we find bundles of true connective tissue and inter- laced undulating elastic fibres resembling the same elements existing in the subcutaneous connective tissue. It is probable that it is with one of these patho- logical cases that Martin had to do in his examination of the choledic duct, when he claims to have found two planes of muscular fibres, the one internal, longitudinal, the other external, of circular fibres. So then, it is well settled that the excretory bile ducts are fibro-muscular tubes which are the seat of more or less energetic contractions, as has been shown by the re- searches of Audige, of Laborde and myself. You will see later the capital importance of these facts. Laborde has shown that tinder the influence of induc- tion currents the gall-bladder and even the bile ducts, hepatic, cystic, and choledic, undergo a slow but very mani- fest contraction. Let us now examine the calculi which sometimes pass through these ducts. They offer a variable volume, and their number is variable also. In the vast majority of cases they are constituted by choles- terine or bile pigment, forming stratified layers of dif- It is by an insensible transition that this difference of appearance between the elastic fibres and simple connective- tissue fibres presents itself as you dissect away from the cavity of the duct. We may then divide the wall proper of the choledochus into three coats which are insensibly blended; an internal con- nective and sub-epithelial coat, a middle coat of very close elastic fibres, and an external coat of connective tissue bundles and undulating elastic fibres. It is in this last coat that we find here and there a few scattered elements of smooth muscular fibres. ferent colors, according as they are more or less tinted by bilirubin. The number of calculi is very variable. Ordinarily from five to twenty are found in the gall bladder. In other cases they are single; in other cases a considerable number are met with. In a woman, 61 years of age, Frerichs counted 1950. Morgagni has counted 3000, Hoffman 3606, and in the collec- tion of Osto there is a gall bladder containing 7802 calculi. All the calculi contained in the gall bladder, whatever the number, are of the same chemical composition, color and structure. Their size is variable, from a grain of millet seed to a hen’s egg. Fauconneau-Dufresne has divided gall stones into three classes: 1. Those of small size from a grain of sand to a small pea. 2. Middle size, from a small pea up to a filbert. 3. Large size, from a filbert up to a hen’s egg. The calculi may be olivary, pisiform, lenticular, poly- hedric, cylindric, cubic, finger shaped, have the form of dice, of coins, of pyramids, etc. They may be smooth, hollow and striated, etc. But the ordinary typical form is the olive- shaped. The solitary calculi are roundish or ovoid. Multiple calculi ordinarily present facets, which appear to be due to the massing together of the calculi, and not to the friction of one upon another, for you do not often find, on examining gall stones, any interruption in the lamellae which constitute them, which would be apt to take place if the facet was the re- sult of friction. Nevertheless, in 1851, Barth found in the gall bladder of a woman of 63 years, a dozen irregular calculi, with rough sur- faces; he remarked that certain of these calculi had been broken and a little worn by friction. Other observers have recorded similar facts. Some have found in the gall bladder, not stones properly so called, but a thick pasty whitish mass com- posed almost entirely of cholesterine (Besnier), or even a bili- ary sediment of the consistence of mud (Durand-Fardel). Ordinarily, however, the biliary concretions are quite con- sistent, although they are marked easily by the finger nail; the hardest calculi are those of cholesterine. The structure of the calculi is variable, and has been well studied by numerous authorities, who have differently divided these biliary concretions. Walter’s classification is; ist. The striated calculi, transparent or opaque, which may be either smooth or anfractuous; 2nd. The lamellated calculi, whose substance is disposed in layers around a nucleus; 3rd. Calculi enveloped by a cortex.—Hein’s classification is “ simple cal- culi;” 2, “ composite calculi.” Frerichs divides calculi into: 1. Simple homogenous calculi, whose structure is uniform, whose fracture presents an earthy, soapy, or crystalline surface, and which have neither nucleus nor cortex. 2. Composite calculi presenting a central nucleus surrounded by a zone more or less thick, and covered by a cortex. The nucleus, brown or black, is com- posed of colepyrrhine and lime, cholate of lime, or of choles- terine. The nucleus, ordinarily single and central, is sometimes excentric. There may even be in a calculus several nuclei. In a dry state these nuclei may undergo a sort of retraction, become split or even fragmented. The smaller the calculus, as a rule, the larger the nucleus. Cases have been mentioned in which the nucleus was constituted by a foreign body, such as a lumbricus or blood clot. The middle layer, immediately surrounding the nucleus, is generally striated, and constituted by crystals of cholesterine, pure or mingled with pigment. Concentric zones are also generally observed, indicating the growth of the calculus by successive strata. The cortex is generally more or less thick, sometimes smooth and sometimes mammillated, but it is clearly distin- guished from the middle layer by its color, its stratified appear- ance and its consistence. It is formed either of cholesterine, of bile pigment or of lime. Biliary calculi are formed at the expense of the elements of the bile; rarely they are composed of a single substance, they are ordinarily mixed. Cholesterine is generally the basis of these stones; next in the order of frequency come bile pig- ment and lime salts. Charles Robin divides calculi into calculi of cholesterine and calculi of coloring matter. Those of cholesterine pure are colorless or pearly white. Subjected on platinum foil to a lamp flame, they first melt, then burn like a fatty substance, giving off a sooty light. If the calculus is composed of pure choles- terine, there remains no residue on the platinum foil. Insolu- ble in caustic potash and soda, they are very soluble in boiling alcohol and in ether. A drop of this ethereal solution under the microscope gives colorless rhomboidal plates by evapora- tion. Concentrated H2 So4 colors these calculi yellow, and boiling nitric acid transforms them into cholesteric acid. The calculi of the coloring matter of the bile (biliverdine and cholepyrrhinc) are brown, black or dark, deep green or greenish, according to the quantity of coloring matter. They do not melt when heated, they burn without flame, and leave a sooty residue. They are insoluble in ether and alkaline liquids. Treated by nitric acid, they pass successively through different shades of colors; green, blue, violet, red and yellow. To ascertain the composition of the calculi, Luton, of Rheims, has proposed a very simple method of analysis, which consists in subjecting a portion of the calculus to the action of solvents, hot alcohol, for instance, then allowing it to become cold; crystallization takes place and the microscope enables you to recognize the principal constituent elements of the calculus; rhomboidal plates of cholesterine, needles and bacillary crystals of cholate of lime, etc., etc. The following is a recent analysis of a biliary calculus of a woman thirty-four years of age (Bettmann): Cholesterine 79.00 Fatty matters 0.80 Water 7.41 Mineral elements 3.23 Glycocholate and taurocholate of soda 5.28 Mucus and coloring matters 2.69 Loss o-73 Under the name of biliary gravel, Fauconneau-Dufresne classes only such concretions as are under the size of the smallest lentil, and which present no appearance of structure. He gives three varieties: cholesteric gravel, pigmentary gravel, and melanic or carbonaceous gravel. I have said that the size is variable; in fact from the calculus which is as large as a hen’s egg and fills the gall bladder, down to the little grains of sand constituting what Fauconneau-Dufresne calls hepatic gravel, you will find gall stones of all dimensions. You may also find calcareous concretions in the ducts; but this is a matter which it is not a part of our present plan to treat of, for this calcareous hthiasis never takes place except when, from some cause, the gall bladder becomes obliterated. These calculi, then, play no part in the production of hepatic colic, which is our present subject. What it is of import- ance for us to know is the pathology of these calculi, for if we understand the first cause of their produc- tion, we shall be able, from a therapeutic standpoint, to oppose their formation. I have said that the calculi are constituted by de- posits of cholesterine; what are the circumstances which lead to the precipitation of cholesterine ? We have to study the two following causes: either the cholesterine is precipitated because it is in excess in the bile, or the proportion of cholesterine remains normal, but the other elements of the bile undergo modification and lead to precipitation of the latter. Let us take up the cases where cholesterine is in excess, and here you must recall to mind what you know concerning its origin. Physiologists, as I have told you, are agreed in accepting Flint’s conclusions, deduced from his careful experiments, and in con- sidering this substance as a product of disassimilation of the nervous system. This experimental datum seems to be confirmed, in a certain measure, by clini- cal experience, for it is principally in women with highly developed nervous systems that you observe biliary lithiasis; and for my part, the more my atten- tion has been directed to this explanation, the more firm is my conviction as to its truth. It is chiefly young women, nervous and impres- sible, who are the subjects of hepatic colic. It is probable that in these cases the too active exercise of the cerebro-spinal axis explains the excessive pro- duction of cholesterine and its precipitation in conse- quence of over-production, and I am convinced that this circumstance has not been sufficiently taken ac- count of by the different authorities who have con- sidered this question. The second cause of the precipitation of choles- terine, i. e., the modifications of its vehicle, the quan- tity of this substance remaining the same, has been studied by Thenard, who has indicated, as a factor which may bring about this precipitation, the diminu- tion of the salts of sodium. Moreover, Bramson has shown that the appearance of lime in the bile may cause the precipitation of the coloring matter. Lastly, the bile which in the normal state is alkaline may be- come acid, and this is especially likely to take place under the influence of animal diet; and acid bile favors the precipitation of cholesterine. Moreover, as we frequently find a nucleus of mucus in these calculi, we must assign an important role to the inflammations of the bile ducts; these in- flammations cause a hyper-secretion of mucus which may give rise to a nucleus, around which the choles- terine deposits itself. Such are the physical and chemical causes which favor the production of calculi. Let us now inquire what are the individual causes. Women, as you know, are the most frequent sub- jects of biliary lithiasis, for statistics show that twice as many women as men suffer from this disease. (Durand-Fardel’s statistics (1868) show that out of 230 cases, 142 were women, and 88 were men. Senac’s statistics, out of a total of 311 individuals, give 227 women). With reference to individual causes, an im- portant part has been assigned to diet; it has been maintained that a too fatty regimen is one of the most prolific causes of biliary calculi. I believe this state- ment to be somewhat overdrawn. It has not, in fact, been proved, either by experimental or chemical ob- servations, that a diet exclusively of fatty food predis- poses more than any other to biliary lithiasis, and the observations which have been made among people living on oleaginous food, as the people of the far north, the Norwegians, the Esquimaux, etc., do not prove that they are more subject to hepatic colic than other nations which consume less of fatty substances. But if the influence of these fatty aliments is not demonstrated, there is another factor which in my opinion plays an important part in pathogeny, namely, allowing too long an interval to elapse between meals. Physiology in fact teaches that during digestion the bile flows in great abundance into the duodenum, and that the gall bladder nearly or quite empties itself at this time. We know also that one of the predominant causes of the precipitation of cholesterine in the bile is the prolonged sojourn of that liquid in the gall bladder. When the meals are too far apart, or when, as is the practice of some persons, only one meal a day is eaten, the gall bladder is placed in a favorable condition for the precipitation of cholesterine. There is another factor which also aids the flow of bile, viz., the respiratory movements, wTich by the pressure which they effect upon the gall bladder and the intestinal mass through the intermediation of the diaphragm tend to empty the gall bladder. Hence the influence of want of exercise on the production of these calculi is apparent, and it is in fact, sedentary persons whom we find to be the most subject to biliary lithiasis. Add that active respiratory movements favor the combustion of fatty matters, and you easily understand why we assign the first place to exercise in the hygiene of lithiasis.* The diatheses have a notable influence on the production of biliary lithiasis, and despite the opposi- tion of Durand-Fardel to the doctrine of Willemin who maintains that biliary lithiasis, like urinary lithiasis, depends on the uric diathesis, it is none the less true that we find more cases of biliary calculi among the arthritic than among any other class of people. Heredity seems also to play a prominent part in biliary lithiasis. Petit and Willemin cite examples, as also do Budd and Fauconneau-Dufresne. Senac, in studying the family health and constitution of patients who have consulted him, has so often met with differ- ent manifestations of the arthritic diathesis, that he believes this diathesis to be an important factor in biliary lithiasis. To the support of this view, he brings forward a certain * Consult the following authorities: Budd on Diseases of the Liver, London, 1857; Frerich's, on Diseases of the Liver, Wm. Wood & Co., 1879; Fauconneau-Dufresne, Treatise on Calculous Affections of the Liver; Willemin, on the Treatment of Hepatic Colic by Vichy Water, Beneke in Deutsch. Archiv. f. Klin. Med., 1876, etc., etc. number of observations which seem to place the matter beyond all doubt. According to Senac, individuals smitten with hepatic colic are not attacked in a state of health; the hepatic disease either succeeds existing pathological states or adds itself to states that have previously existed. Migraine, uric lithiasis, diathetic coryzas, hemorrhoids with or without hemorrhage, acute or chronic arthrites of rheumatic or gouty nature, urti- caria, eczema, acne rosacea, etc.; pregnancy, accouchement, menstruation, the menopause, suppression of a bloody flux or an habitual discharge, forced rest, the depressing moral emo- tions, affections of the liver, in fact all causes capable of modi- fying the hepatic circulation, may, it is said, determine the outbreak of hepatic colic. Beneke has also set forth the relation which exists between atheromatous degeneration of the arteries and biliary lithiasis. He has found that in three-fourths of his cases (350 autopsies made by him at Marbourg) there was atheromatous degeneration of the arteries along with biliary lithiasis.* To sum up, all the facts go to prove, as Bouchard has well shown, that the cause of biliary calculi resides essentially and primarily in a general disturbance of nutritionf. * Beneke, Gallensteintildung Atheromatose Arterienen- tartung und Fettsbildung (Arch. f. Klin. Med., 1876). f This is the way Bouchard expresses himself: “ Biliary lithiasis manifests itself only in individuals whose nutrition is retarded; in those affected with that nutritive vice of which one of the consequences is to prevent the destruction of acids, and to cause their accumulation in the organism, to diminish the alkalinity of the humors, to take lime from the anatomical elements, and with it impregnate the liquids of excretion.” (Maladies par Ralentissement de la Nutrition, p. 85), We know now the causes which are operative in the formation of calculi, and we have studied the an- atomy of the bile ducts. Let us now consider the mode of passage of gall stones in the different ducts, and the accidents which may result from their presence. In the immense majority of cases, calculi form in the gall bladder; this is where the major part of the bile accumulates and sojourns; nevertheless, in certain circumstances true biliary gravel has been known to be deposited in the hepatic bile ducts and to manifest its presence in the radicles of the hepatic duct and in the hepatic duct itself. But such facts are exceptional; ordinarily the calculus, when formed in the gall blad- der, may increase in size and remain there a long time without determining any symptom, and this is so true that at the autopsies of the aged women at the Sal- petriere, it may be said that it is the rule to find in the gall bladder calculi more or less voluminous, without any disturbance having been noted during life there- from. But at other times, calculi of little size pass with the bile into the cystic duct and thence into the ductus choledochus, and are voided by the intestine. These calculi may make their journey from the gall bladder to the intestine without causing any attack of colic, and in my own practice I observed several years ago, a very curious instance in one of my patients who had been passing by stool a considerable quantity of biliary gravel without ever feeling any colicky pains. At the same time, there generally ensues an aggregate of painful symptoms described under the name of hepatic colic. In 1873, I made with Dr. Audige (a) numerous experiments in order to obtain a clearer understand- ing of the way these gall stones pass through the biliary passages. We first of all discovered in animals that the bile ducts when irritated are the seat of a real spasm, which is, moreover, easily explained, if you re- call to mind the anatomical structure of these ducts. Then we artificially reproduced the attack of hepatic colic, for after having introduced into the common bile duct of dogs by the intestinal opening certain foreign bodies, we observed the extreme sensibility of these conduits in these animals and the mode of pass- age of the calculi, which by reason of the spasmodic movement of which the ducts are the seat, either travel towards the intestine or gall bladder.* This is a fact of capital importance, which even justifies the affirmation that when, in persons affected with biliary colic, you do not find the offending body (a) Dujardin-Reaumetz, Etude sur le spasme des voies biliaires, k propos du traitement de la colique hepatique (Bull, de therap., 1873, t. LXXXV, p. 305).—Audige, Researches ex- perimentales sur le spasme des voies biliaires, a propos du traitement de la colique hepatique. These de Paris, 1874. * These are the conclusions of the thesis of Audige: (1). The treatment of hepatic colic should consist in diminishing the contraction of the bile ducts and the pain therefrom resulting: (2). Anaesthetics and morphine em- ployed subcutaneously fulfill this end.” —the corps du delit—in the stools, you should not at once conclude that the calculus does not exist, and make the diagnosis of hepatalgia. It may happen, in fact, that the calculus, after having traversed the duc- tus choledochus a part of the way towards its intes- tinal opening, shall return to its starting point and fall back into the gall bladder. These experimental researches, which have since been confirmed by Laborde, demonstrate that in hep- atic colic there is a veritable painful spasm of the bile ducts.* I. The bile ducts are endowed with contractility, and may consequently enter into a state of spasm under the influ- ence of an excitation direct or indirect; this contractility is of the same kind as that pertaining to the smooth muscular flbresof organic life, and the existence of these fibres in the bile ducts is demonstrated both by histological examination and experimental physiology. * These are the conclusions of the work of M. Laborde: 2. The mucous membrane of these ducts is endowed with a very high sensibility, which shows itself, under the ac- tion of excitants more or less intense, by pain and its expres- sion, and by certain reflex symptoms whose immediate manifes- tation is spasm of the ducts. 3. These phenomena are especially determined by the presence and contact of foreign bodies (biliary calculi) whose spontaneous migration is, for that reason, rendered very diffi- cult, and is not effected till after a variable time; and there is this peculiarity attending this migration, that these bodies may re- turn to the gall bladder instead of passing downward to the intestine. 4. Anaesthetics and antispasmodics are best adapted to 62 Trousseau’s penetrating mind understood this spasmodic action of the bile ducts. In the very faith- ful description which he has given in his Clinical Medicine* of hepatic colic, he speaks of the ejacula- tion of bile into the intestine, and assigns a consider- able role to the muscular layer of these ducts. Senac, however, the author of a remarkable study on the treatment of hepatic colic published in 1870, has most clearly shown the importance of these spasms. Hence, from the point of view of general pathology, there is good warrant for placing the acute accidents determined by the passage of gall stones through the excretory ducts of the liver in the great group of colics, which, as the treatment of this morbid state, of which it is easy to realize experimentally the mechanical conditions. 5. These medicaments, notably morphine, chloroform, hydrate of chloral, act by exercising an immediate anaesthetic and paralyzing influence, whence result the cessation of the spasmodic state, distention of the ducts, and the accumulation of bile, which acts upon the foreign body after the manner of a vis h tergo and forces it towards the intestine. 6. The association of hydrochlorate of morphine with chloroform or hydrate of chloral (i. e., the simultaneous ad- ministration of these medicinal agents) constitutes the most powerful means for obtaining the results indicated, viz: anaes- thesia of the bile ducts and consequent cessation of pain, and a favorable influence on the migration and rapid expulsion of the foreign bodies.

Bull, de Therap., 1873-74. *Trousseau, Clirique Medicale de 1 Hotel Dieu de Paris. you know, are properly defined as the painful con- tractions of mucous tubes which have a muscular layer. Pardon me for dwelling so long upon these points, but you will see that from a therapeutic standpoint the recognition of the spasmodic element in hepatic colic is of the utmost importance. When a gall stone is formed, either it produces no marked symptoms, as I have before said, or it gives rise to two orders of phenomena, viz; the acute pain- ful symptoms of hepatic colic, or, as is sometimes the case, a train of obscure symptoms with slow evolution and often of difficult diagnosis. I can not here give you a lengthy description of hepatic colic, and must refer you therefor to your text books. I must however remind you that this af- fection, so rarely fatal, may be complicated with grave accompaniments. Sometimes there is an inflamma- tion of the bile ducts and gall bladder sufficiently in- tense to give rise to peritonitis of a more or less spreading character; in other cases less well known (and it is for this reason that I mention them), the pain is so sever as to produce lipothymia and fatal syncope.* * Hepatic colic may be preceded by prodromes: vague pains, cramps of the stomach, weight in the hepatic region; but often it begins suddenly by a pain which appears with or without appreciable cause, several hours after a meal. This pain rapidly attains its maximum. It is atrocious, paroxysmal; If hepatic colic in its ordinary form is quite easy of diagnosis, there are masked forms sufficiently common which often pass unperceived, and which at the same time by their symptoms indicate to the prac- ticed eye the presence of biliary lithiasis. We have it compels the patient to cry out. According to Durand-Fardel, the maximum of this pain is in the right hypochondriac region; according to Senac, on the contrary, it is in the epigastrium, and it is from this region that the pain radiates to the sides and posterior part of the body, to the vertebral column, to one or both shoulders, etc. The patients are taken with extreme restlessness, they do not find any comfortable position in bed. There is one posi- tion to which Durand-Fardel cells attention, which they seem to prefer, viz; the sitting posture with the body bent forwards, the head resting on the knees. At the beginning of the paroxysms, you sometimes ob- serve a severe chill, epigastric distress, with vertigo, nausea, and vomiting, first of food then of bile; sometimes, also the patients may have convulsions, hysterical attacks, etc. Coinci- dently with the first attack, jaundice may appear; it is how- ever sometimes wanting, especially in mild cases; it is variable both in intensity and extent, may remain limited to the sclero- tics, to the circumference of the nose, or mouth, or may in- vade the whole body. During the entire attack, you observe little or no change in the pulse and temperature. Pressure over the liver is painful, and it is with difficulty that by palpa- tion and percussion you can detect congestion of the organ. After the attack, the patients suffer from general lassitude, which is in ratio of the intensity of the attack; there is often, also, want of appetite, nausea and vomiting; the bowels are al- ways constipated; the urine is of a deep wine color, and con- tains the coloring matter of the bile. cases where gastric symptoms predominate, and Senac has also done well in insisting upon this point; in fact the majority of patients affected with gall stones (sixty-five per cent.) suffer from painful cramps in the stomach. This variety of dyspepsia called hepatic dyspepsia, which I mentioned while on the treatment of affections of the stomach, has been studied by Cor- nillon, who has called attention to its frequency.* * Fauconneau-Dufresne says also that we must refer to the accompaniments of lithiasis, many of the pains called cramps of the stomach, or regarded as spasmodic, neuralgic or rheumatic affections. Willemin also indicates a prodromic period, constituted by dyspepsia, or gastric troubles recurring more or less often. Senac has also noticed similar cases among persons sent to Vichy to be treated for “gastralgia” or “cramps of the stomach.” In some patients you have only these attacks of gastric cramp as a guide to diagnosis; in others, after the attack, you will notice that the urine is of a wine tint more or less marked;: sometimes there is a jaundiced hue of the skin, which suffices to clear up the diagnosis. Out of one hundred observations, Senac found sixty five in which the only symptoms were of a gastric order: Cramps of the stomach 26 ) , Gastralgias 20 \ Dyspepsia 19 Pain in the epigastric region and in the back, 3 Pain in the stomach and liver 3 Hepatic pains 7 Sudden onset of the affection by well marked hepatic tolic, 15 Cases where the existence or absence of prodromes was not mentioned 7 100 To these gastralgic phenomena we may add an- other symptom quite as characteristic, namely, the ap- pearance of remittent febrile attacks. Senac, who is so excellent authority on these subjects,* has shown that these intermittent attacks appear between four o’clock and six o’clock in the afternoon. They are accessions of little intensity, but in some cases, as Charcot has pointed out, they may take on the char- acter of real pernicious paroxysms like those seen in the worst forms of malaria. We have here something very similar to what takes place in connection with states of the urinary passages when you catheterize certain individuals. You well know that febrile at- tacks of an intermittent character are often thereby provoked. It is the same with the bile ducts, where the presence of foreign bodies is the occasion of simi- lar reflex symptoms. I can affirm the reality of these facts; so whenever you have a patient with the symptoms of painful dys- pepsia, in whom you observe a slight febrile move- ment coming on between four and five o’clock in the afternoon, especially if you notice a slight jaundiced hue which may be scarcely appreciable; moreover, if you find the region of the gall bladder sensitive and pain produced on pressure, you are warranted in affirming the presence of gall stones. As you see, I have dwelt at some length on the pathogeny and symptoms of biliary lithiasis. I have *Senac, Treatment of Hepatic Colic; 1870. deemed it necessary to do so, because, before under- taking the treatment, you should have mastered well the first causes of the lithiasis and its accompaniments, in order the more certainly and methodically to meet them. The treatment of biliary lithiasis should fulfil the three following indications; To meet and allay the symptoms determined by the presence of the calculus; to attempt the solution of the latter, if this be possible; lastly, to prevent their formation. Let us consider the first indication, viz.: to combat the pain. This, as before said, ordinarily takes the form of colic. I shall not concern myself with those rare cases which belong rather to the domain of surgery, and which are connected with ulceration of the gall bladder by the calculi and the passage of the latter through the abdominal walls, and shall restrict myself to the treatment of the colic itself. But before proceeding any farther, we must settle the question, Ought we to treat the colic at all ? I have told you, in fact, that the reflex and painful symptoms which characterize the colic are determined by the passage of calculi through the bile ducts; this passage is necessary; it is the only natural means of getting rid of the trouble. The attack of colic is then, as Durand-Fardel has said, a necessary evil, and we ought not, properly speaking, to treat the colic, if by the word treat we are to understand to oppose the passage of the calculus and its movements toward the intestine, which ought to be favored rather than hindered. But we ought to render this transit as easy and painless as possible; and our duty is to relieve the suf- fering of the patient. To attain this result, there are four great therapeutic agents which we may employ: morphine,* chloral, chloroform and antipyrine. Do not forget that one of the modes of introduc- tion of medicaments, namely by the primce vice, is often denied us by reason of the continual vomiting of the patient, and that we are obliged, in order that our medicines may be absorbed and do good, to in- troduce them by the skin, the rectum, or the respira- tory passages. Of these three channels the sub- cutaneous is the preferable one, and I recommend you to employ a combination of morphine and atropine, of which the following is a useful formula: IJ Morphinae hydrochloratis, 10 centigrams. Atropinse sulph., i centigram. Cherry laurel water, 20 grammes. M. Otie cubic c. m. of this solution, or a hypodermic syringeful, contains Yz c. g. of morphine and Y* m. g. of atropine. *A useful combination for hepatic colic is that known as chlorodyne or chloranodyne (P., D. & Co.), which contains chloroform and morphine. Dose, fifteen drops.—Tr. This treatment is to-day very generally adopted, but there are those who object to it. Senac has shown himself one of the most determined opponents of these injections, and from what follows you will understand the grounds of his opposition. In my experimental researches on spasm of the bile ducts, I had shown the reality of this spasm, and also explained the true mechanism of the colic; Laborde had confirmed these experiments, and our conclusion was a natural one, that morphine associated with atropine was the best remedial agent in our pos- session, as these alkaloids moderate the contraction of the smooth muscular fibres. But Senac, who had also taken up this idea of spasm, and was one of the first to put it in clear light, replied: “ The contraction is necessary to the transit of the gall stone, and by your morphine injections you hinder the passage of the cal- culus into the intestine and thus you retard the cure of your patient.” Who is to be judge in this dispute? Clinical ex- perience must decide. Never (and I emphasize the word never) in innumberable cases of hepatic colic have morphine injections appeared to pro- long colic, and always practitioners have obtained from these injections relief of pain. The explanation seems simple enough. We recognize the fact that morphine, like atropine, opposes to a certain extent spasm of the unstriped fibres, but who will say that when this spasm exceeds certain limits, instead of favoring the passage of the calculus, it does not arrest it in its course by excess of contraction ? However this may be, Senac has relaxed somewhat of his rigor, and to-day, like the greater number of physicians, he resorts to morphine injections in the most painful cases. Before having recourse to injections of morphine, which are to be reserved for cases of great severity, in hepatic colic of medium intensity you may employ- anodyne suppositories, of which the following is a good formula: 5 Ext. belladonnae, I centigramme. Ext. opii, 2 centigrammes. Olei theobrom., 3 grammes. Cerse albse, q. s. M.—For one Suppository. Chloral is also an excellent medicament when given in lavement according to the method which I advise, and which consists in dissolving two or three grammes in a cup of milk, in which the yolk of an egg has been beaten up, Unfortunately, chloral cannot render us great service, for, generally, patients under the tyranny of their colic cannot retain these injec- tions. Lastly, there is another means which I advise you to employ whenever, after injections of morphine, the pain still keeps its intensity. I cannot describe the agony of some typical cases of hepatic colic; you must be present yourself and witness this suffering, the incessant cries of the patient, the almost delirous agitation which nervous patients man- ifest. In these cases you may use chloroform by in- halation, following the method which obstetricians have popularized, and which has been called obstetrical ancesthesia. Administer the chloroform delicately, i.e., pour ten, twenty or thirty drops upon a handkerchief, and let the patient inhale the anaesthetic; these inhala- tions you can repeat till you have obtained abatement of the pain with conservation of the intelligence. This, as you are aware, is Simpson’s obstetric method; which has been also defended by Campbell. (*) I have not spoken of the internal administration of chloroform, which Corlieu, a long time ago, ex- because administration by the stomach is very difficult, and because it is proved that this method is less efficacious than by the respiratory passages. I may say the same of the chloroform ointments in which some seem to have faith, but which hardly seem to me to have the merit of placebos. However, as saturated chloroform water has been vaunted by some authorities, notably Lesegue and Regnauld, you may employ this chloroform water for the intense pains in the stomach which individuals often suffer from who are victims of biliary lithiasis. Chloroform water is made by agitating a little chloro- *Gaz. des Hop. 1856. tUnion Medicale, 1847. form in pure water and allowing it to settle. The supernatant liquid which is decanted off contains a minute quantity of chloroform. If you administer chloroform water, you can prescribe it in the follow- ing way: 1J Saturated chloroform water, 60 grams (2 f|) Orange flower water, 30 grams (1 f § ). Syrup of poppy, 30 grams (1 f § ). Sig.—A tablespoonful every quarter of an hour till the pains cease. The analgesic properties of antipyrine have been applied by Germain See to the treatment of biliary lithiasis, and the professor has shown us the benefits which may be derived from it. I have myself often had recourse to antipyrine in bilious colic, and in certain cases I have obtained real service therefrom. You can employ the hypodermic or the rectal method. The hypodermic injections may be thus formulated: Antipyrine, grams v. Water, grams xx. As these solutions are often painful, I prefer sup- positories of antipyrine, or small rectal injections con- taining a gram of the medicament. M. Sig. Inject a whole syringeful of this solution. To these principal means you may add iced drinks and especially iced milk, warm baths, cata- plasms over the hepatic region, and even the applica- tion of ice to the region of the liver. So much for the treatment of hepatic colic. The attack yields at the end of several hours or of several days, according to circumstances, then disappears al- most suddenly, and the patient finds the offending body in the stools. The diagnosis is settled; you know beyond doubt that the patient is affected with biliary lithiasis, and it is probable that he will again be afflicted in the same way. Do we possess any means of preventing these re- currences, i. e., is it possible to effect solution of those calculi which remain in the gall bladder ? In other words, is there a lithontriptic treatment of biliary calculus ? I believe we may reply categorically in the negative to this question, and at the same time, there is a certain number of remedies which are said to possess this property. The most noted certainly is Durande’s Solvent which consists of turpentine and sulphuric ether. Jean Francois Durande who died in 1704 was physician and professor of Botany in this city (Paris). His formula for the solution of gall stones was as follows: B Olei Terebinthinse, 3ij (8 grams), Sulph. ether, 3 iij (12 grams. M. Sig.—Half a teaspoonful to a teaspoonful in the morning, or night and morning. This remedy is to be given in the morning along with glycerine or syrup, and washed down with a little whey or broth. The same dose may be repeated in the evening. Durande recommended to continue the usage of his specific till the patient had taken 500 grams (or about a pint); the medicine to be suspended, if irritation of the stomach should follow. At the same time that he gave this preparation, Durandc subjected his patient to a severe regimen with emollients and sometimes even practised blood letting. Various modifications of Durande’s formula have been proposed, thus, the proportion of turpentine has been aug- mented (2 parts turpentine to one of ether) or the proportion of ether has been augmented (2 parts ether to one of turpen- tine). Turpentine is a very disagreeable remedy to take, and it is for this reason that its administration in cap- sules as Trousseau recommends, is preferable to the administration in emulsion: Trousseau’s method was to give one capsule of turpentine and two of ether several times during the day. Some have explained the action of the turpentine and ether mixture on the principle that gall stones in a capsule dissolve in such a menstruum. This chem- ical solution, however, is not as complete as you would suppose, but even admitting the chemical fact as true, it can not explain the results of the remedy when given internally. It is not to be supposed that these two substances when taken by mouth pass without transformation through the stomach and duodenum to reach the gall bladder by traversing the bile ducts, and there produce their solvent action. The explana- tion is then erroneous, and yet it must be admitted that this remedy has possessed and still possesses a great reputation based upon its clinical results, for there exist very many observations in which the employ- ment of this means has attenuated and distanced the attacks of colic. I do not believe that these favorable results imply the possibility of solution of the calculi, but they are doubtless due to the antispasmodic and calmative action of the ether and turpentine mixture, and not to any lithontriptic action. But however this may be, as the remedy easily fatigues the stomach, and as its antispasmodic properties are inferior to those of the other medicaments of which I have spoken, I think it is better to discard it altogether. What I have said of Durande’s “specific,” I would apply also to the terebinthinate soap proposed by Franck (a mixture of sweet almond oil, turpentine, and caustic soda), to chloroform, counselled as a solv- ent by Corlieu, Rouchut and Gobley, and I say the same of the choleate of sodium recommended by Schiff, of the succinate of iron, the effects of which Buckler has vaunted, and, in general, of all those sub- stances which have been considered as solvents of biliary calculi.* * Corlieu was the first to counsel the employment of chloroform as a solvent of calculi. His formula is as follows: 9 Chloroform, grams ij. Alcohol, grams xvj. Water, grams ccc. M. Gobley has shown that cholesterine dissolves more rapid- ly in chloroform than in ether. Cholagogues have also a considerable part in the treatment of biliary lithiasis; by favoring the flow of bile they oppose one of the frequent causes of the de- position of cholesterine, and as podophyllin is one of the most powerful cholagogues known, you will not be surprised that it has been recommended in these cases, As for myself, I much prefer euonymin, and to all my patients affected with biliary lithiasis, I order- two of the following pills on going to bed: Schiff considers that the precipitation of cholesterine is due to want of cholate of soda and potash in the bile. He therefore counsels the administration of two or three grains of choleate of soda thrice a day; the medicine to be continued until the economy is thoroughly under its influence, as is shown by irregularity of the pulse, which becomes very slow by rest, and markedly accelerated by the movements of the patient. Buckler, of Baltimore, has advised chloroform, five drops every four hours, and the succinate of iron in the dose of a tea- spoonful after each meal. He affirms that the succinate of iron has the power to dissolve cholesterine even in the blood, by setting free a considerable quantity of nascent oxygen. Buck- ler has affirmed that by this process he has rapidly obtained the solution of all the calculi that he has been called upon to treat. Lothromp declares that for eighteen years he has treated with success more than twenty cases of biliary lithiasis with the succinate of iron alone. Dabney (Am. Jour. Med. Sc., 1876,) also vaunts the em- ployment of choleate of soda as a preventive of the formation of gall stones. He gives five grains twice a day. Enonymin, Castile soap, aa 3 grammes (gr. xlv). F. S. A. pil, No. xxx. The really curative treatment of biliary lithiasis is the thermal treatment, i. e., by the natural alkaline waters, and there are two spas especially whose waters are efficacious in these cases; I refer to Vichy and Carlsbad. You remember that while speaking of chola- gogues, I mentioned the want of agreement which exists on this point between clinicians and physio- logists, and I have shown you how we must explain the undoubted curative action of these waters. Surely, it is not by dissolving the calculus that these waters act, but by ameliorating the digestive functions, by regulating nutrition, by diminishing the hepatic con- gestion which almost always accompanies the presence of calculi, lastly, by modifying the bile itself. What differences exist between the waters of Carlsbad and Vichy, these two rival stations which possess an equal reputation acquired by innumer- able cures ? It is chiefly owing to their richness in sodium bicarbonate that the waters of Vichy are efficacious. And it is chiefly to sodium sulphate that we are to look for the curative element in Carlsbad.* *The Vichy Springs belong to Allier, a province in Central France. They are strongly alkaline; their temperature varies between 44° and 14° C.; their richness in sodium bicar- bonate is aoout 5 grammes per litre. There are 11 of these Of the various Vichy waters, the Hopital spring is the best for biliary lithiasis; the patient may drink a tumbler full four times a day. Of the Carlsbad waters, Sprudel is to be preferred. Add, that at this latter station the alimentary regimen is very severe, and at all the hotels patients are subjected to a uniform diet, which plays a considerable role in the treatment at these stations.* springs, of which 4 are cold springs, the waters of which are fit for transportation. We have no alkaline springs in this country comparable with these Vichy waters unless we except the Congress Springs, of California, which contain 2 grammes per litre of sodic bicarbonate; the Soda Springs of Wilhorts, Oregon, are also strongly alkaline. The Hathorn, Congress, High Rock, Vichy and other of the chloride of sodium waters of Saratoga, the St. Leon (Canada) are often prescribed for biliary lithiasis, and have proved useful in very many cases. The Carlsbad waters (Carlsbad, Bohemia), are the type of sodic sulphate waters. There are 10 principal springs, of which the most important is Sprudel. There are in every litre over 2 grammes sulphate of sodium, and 3 of carbonates of sodium, magnesium and potassium. The taste of the Sprudel water is salty, brackish and strongly alkaline. From two to three glasses are usually drank per day. These Carlsbad waters are alterative and laxative, and have a great reputation in Europe for biliary lithiasis.—Trans. *The Sprudel water gives a sensation of comfort and even of hilarity after drinking it. When taken in quantities not ex- ceeding half a tumblerful, it has little effect, but it becomes purgative after drinking from three to six glasses. This water also produces nervous disturbances of a very curious nature, Whether they act by the bicarbonate or sulphate of sodium which they contain, the waters of Vichy and Carlsbad produce essentially the same effect; i. e., patients experience almost always during the employ of these waters, or, as is most frequently the case, one or two months afterward, new attacks of colic, due to the passing of the calculi. But this is a necessary evil, as I have before shown you, and it is essential that for a period of years the patient shall periodically resort to these waters in order to get completely rid of the biliary lithiasis which causes the calculi. Other thermal stations have also been recom- mended, but they occupy a second rank in the treat- ment of biliary lithiasis. I refer to Vittel, Contrexi- ville, Niederbronn, and Capvern. The sodium sul- phate waters ought all to enter into this group of lithontriptic waters, and we must place at the head of these waters, not the Hunyadi Janos, which contains sulphate of magnesia, a salt which is but slightly cholagogue, but the Rubinat water, which contains sulphate of sodium in larger proportion than almost any other mineral water. After the employment of mineral waters, we must which may be compared to drunkenness; vertigo, dazzling sensations, loss of memory, etc. By evaporating Sprudei water, a salt is obtained very much in use in Germany as a purgative, and known as Carls- bad salt; the composition is almost exclusively sodium sulphate. Sprudei water contains 2.27 grammes of this salt per litre. assign the first importance to hygiene in the means at our disposal for the cure of lithiasis. The hygienic regimen should be absolutely based on the different physiological circumstances which, as I showed you at the beginning of this lecture, modify the excretion of bile. Cholesterine, as I have told you, is a product of the disassimilation of the nervous system; urge your patients then to avoid too intense mental emotions and everything that can cause undue exercise of the cerebro-spinal axis. We must, as I have before said, guard against stasis of the bile in the gall bladder. Recommend then exercise, active respiratory movements, which have for their effect both to oxidize fatty matters and hydrocarbons, and to exert pressure on the gall blad- der. Catarrh of the bile ducts, through the mucus which it engenders, may be the commencement of biliary calculi; counsel, then, avoidance of all the pro- ducing causes of catarrh and, and for this end forbid too highly seasoned foods, too generous wines, and too abundant meals. Lastly, from the point of view of diet, without absolutely forbidding fatty foods, I would advise a very moderate use of fats, and urge you above all to insist upon a vegetable rather than an animal diet, for it seems to be demonstrated that it is the acidity of the bile which most favors the precipitation of choles- terine. and this acidity may be produced by a diet largely nitrogenous; but you should be very chary in the permission of starches and sugars, and ever keep before you the excellent precepts given by that master in dietetics, Prof. Bouchardat, as well as the therapeu- tic indications which have so recently been formulated by Prof. Bouchard. Bouchardat’s alimentary regimen for biliary lithiasis is as follows: Eat moderately, abstain from soups containing sorrel, tomatoes, etc., and from strong liquors; regulate the employ- ment of tea and coffee according to their effects. One egg and never more during the day, or entire abstinence from eggs. Meats of all kinds (butcher’s meat, fowl, game) may be per- mitted, but must be used with moderation. It is necessary to be still more reserved in respect to fish, lobsters, cray fishes and crabs, shrimps, and other shell fishes, as well as old cheese. Milk and fresh cheese are unobjection- able. The vegetables and legumes of the season are almost all indicated, and should be a part of every day’s fare. I would particularize spinach, lettuce, chiccory, artichokes, cucumbers, carrots, parsnips, sweet potatoes, asparagus, green beans and peas in moderate quantity. Potatoes are useful and should in part replace bread at meals; bread, in fact, ought to be eaten moderately, and the crust is preferable to the rest of the loaf. Common radishes and black radishes may be eaten freely, also cabbages, cauli- flowers, Brussels cabbage, mushrooms, truffles, chestnuts and other nuts; beans and lentils in moderate quantity are per- mitted. The daily use of water cresses or of salads, lettuce, en- dives, chiccory, Indian cresses, dandelion, corn-salad, viper’s grass, etc., is allowable. All the fruits may be freely eaten (raspberries, peaches, bananas, strawberries, prunes, figs, etc.) The “grape cure” is often beneficial. Olives, almonds, pistachio nuts, etc., in moderate quantity. Little or no beer; the only alcoholic beverage, red or white wine with twice or three times as much water. The sparkling wines are contra-indicated, as well as the effervescing waters. For constipation, Bouchardat recommends to be taken in the morning in sweetened lemonade, a tablespoonful of a mixture of equal parts of Rochelle salts and Glauber salts. The healthy function of the skin should be promoted by a sponge bath in the morning, followed by a brisk rub-down with a dry towel or flesh brush, or the naked hand, oiled with a little sweet oil. Once or twice a week, a hygienic alkaline bath (three ounces carbonated potash, half a drachm of essence of lavender, a drachm and a half of compound tincture of benzoin to the water of the bath). These baths to be followed by prolonged rubbing and massage. Lastly, to prevent the formation of calculi, take for the first ten days of the month, morning and evening before meals, a pill containing a grain and a half of tartrate of potassa and lithia; each pill to be washed down with a tumbler of water. For the ten following days, morning and evening, a table- spoonful of a mixture containing the syrup of five roots with a little acetate of potassium. [May be replaced in American practice by the syrup of buckthorn, or the cascara cordial to which acetate of potassium may be added.] For the ten suc- ceeding days of the month, a quart of water every day con- taining in solution a couple drachms of Rochelle salts. In the spring, the patient may take to advantage every morning on rising, four ounces of the juice of herbs (lettuce, ehiccory, dandelion), with 75 grains of acetate of potash. This to be followed up for a month. According to Bouchard, the pathogenetic conditions of tfie production of gall stones are as follows: 1, Excess of cholesterine; 2, Lack of fatty acids; 3, Lack of biliary acids; 4, Lack of alkaline bases; 5, Excess of acids in the organism; 6, Lime in solution in the organism. These unfavorable conditions may depend on the diet, on digestion, on the hepatic function, on general nutrition, and on respiration. In respect to diet, we should exclude brains, blood pud- dings, and the yolk of egg. The ternary aliments should be used with extreme moderation, and fats should be preferred to sweets and starches; farinaceous substances should enter as a very small part into the diet, as well as leguminous substances, being too rich in starch and in lime. Green vegetables and fruits may be sparingly indulged in, notwithstanding the lime and vegetable acids which they contain, sweet effervescent drinks, and especially the sparkling wines, beer, cider, etc., are to be interdicted, but red wine and coffee may be permitted. Hard drinking waters are to be avoided; in fact, the purer the drinking water the better. To favor the biliary secretion, the sodic chloride or sodic sulphate or magnesia sulphate waters are to be recommended (Blue Lick, Lansing, St. Leon, Saratoga and Ballston waters, Freidrichshall, Hombourg, Kissingen, Marienbad, Brides, Pullna, etc.). It is a good plan to send patients to the warm springs of Vichy, or, better still, to Carlsbad. To promote the general nutrition, you should have re- course to all the great stimulants of the nervous system which energize the metamorphoses of the economy. Recommend frictions of the skin, cold affusions, warm salt baths, cold sea baths, exercise in the open air, sea air, mountain air, corporal exercise to be taken fasting and several hours after meals. (Bouchardat on the Hygienic Treatment of Biliary Lithiasis, (Bull, de Th6rap., t. xcix, p. 145). Bouchard, Maladies par ralentissement de la nutrition, Paris, 1882, p. 102). Along with the purely medical treatment I must allude to the surgical treatment of biliary lithiasis. Emboldened by the success attained by antiseptic methods in operations practiced upon the peritoneum, certain physicians have proposed to open the gall bladder for biliary obstruction. When the gall blad- der is distended by large calculi, and the outflow of bile is thereby hindered, these surgeons, following the lead of Godefroy Muller who performed cholecysto- tomy about the middle of the last century, have ad- vised to cut into the gall bladder, and remove stones contained in this sac. Cholecystotomy has been performed by Lawson Tait, of England, by Bernays, of St. Louis, by Parkes, of Chicago, by Langenbrich, of Berlin, by Musser and Keen, of Philadelphia, etc. Some have gone even farther in this direction, and have proposed completely to extirpate the gall bladder and to substitute cholecystectomy for chol- ecystotomy. The future must decide as to the practicability and safety of such surgical interference. It must however be admitted that a great number of surg- eons of our country are becoming every day more strenuous advocates of cholecystotomy. Cholecystotomy was practiced about the middle of the last century by Godefroy Muller, who opened up a biliary fistula, and following it to the gall bladder, broke up a cal- culus and removed it by piecemeal. Afterwards the opera- tion went into oblivion. Since the progress of the antiseptic method, there has been a revival of interest in cholecysto- tomy, and recently Drs. Musser and W. W. Keen, of Phila- delphia, have compiled thirty-five cases in which this opera- tion has been performed, in twenty-five of which it was suc- cessful. In cases of biliary lithiasis with perceptible swelling of the gall bladder, two kinds of operations have been proposed; the incision of the gall bladder and removal of the calculus, or complete extirpation of the gall bladder. Before proceeding to either of these operations, it is necessary to confirm the diagnosis by suitable exploratory methods. Aspiration is often innocuous, but it may give rise to accidents such as haemorrhages or local peritonitis. Through the aspirating needle it is possible to pass a fine probe by which to percuss the calculi. But, according to Keen, the most certain result is furnished by acupunctures. With small steel needles, you may perforate the gall bladder with safety, and determine the presence or absence of calculi. Lastly, the exploratory incision, ordinarily harmless when it is practised with antiseptic precautions, is the best means of detecting calculi in the gall bladder, while enabling you to complete the operation at the same sitting, if the gall bladder be found to contain stones. The different stages of the operation have been carefully mapped out. The incision is made over the centre of the tumor hori- zontally with the lower border of the ribs. It must be large enough to enable the operator to explore the deep parts. The knife should be carried to either side as far as may be neces- sary. All oozing of blood must be stopped before opening the peritoneum. The latter having been penetrated by an opening large enough to admit the finger and even the hand if neces- sary, the exploration of the gall bladder, of the cystic duct, and of the neighboring parts is made with care. If impacted gall stones are found, the gall bladder is opened, emptied of its calculi, and a biliary fistula is established by attaching the opening in the bladder to the lips of the abdominal wound. The fistula gets well in a few days. The gall bladder has also been removed, but the dissec- tion is difficult, gives rise to haemorrhage, and is much the more dangerous operation.* Pardon me, gentlemen, for having so long dwelt on the treatment of biliary lithiasis, but this is a disease of the liver very common in our climate and one which you will often be called upon to treat, and I trust I have givep you hints which will be of use to you in your practice. ’Articles by Drs.

Gentlemen;—ln the previous lecture I alluded to a symptom which almost always accompanies biliary lithiasis, viz.: jaundice. I have reserved the consid- eration of this symptom, so common in affections of the liver, for the present lecture, and shall now study the subject at some length, with the therapeutic indica- tions pertaining thereto. You know that jaundice is characterized by the passage of bilirubin in the blood and in the different humors of the economy; you know also that besides the yellowish color of the integument and conjunctivse, which is the result of the impregnation of the blood by this principle, you find in the urine a sure and pre- cise means of diagnosis by detecting there the pres- ence of bilirubin. One of the most certain tests is the action of nitrous nitric acid, and the multiplicity of colors which it causes; another is the emerald green tint obtained by tincture of iodine, or the azotite (nitrite) of potash.* When you take a general survey of the pathogeny of icterus considered as a symptom of hepatic affec- tions, you find that this symptom sometimes accom- panies obstacles to the excretion of the bile; some- times, on the contrary, these obstacles do not exist, and the bile flows freely into the intestine, but jaundice none the less ensues; lastly, sometimes the jaundice is * Jaundiced urine is of a more or less deep greenish- yellow color, and stains linen. As a test for bilirubin, the nitrous nitric acid test is the best. Filter a little of the urine, and from a pipette, let fall a few drops of this acid (nitric, with a little nitrous) on a small quantity of the filtered urine in a test-tube. You observe a play of colors: green, blue, violet, red and yellow. In doubtful cases, you can employ the following means; Agitate a little of the urine with hot chloroform, which dis- solves bilirubin, then pour off the chloroform, filter and drop in a little nitric acid which floats upon the chloroform; the play of colors is produced if there be bilirubin present. The tincture of iodine test is applied in this manner: Filter a little of the urine and add a few drops of tincture of iodine. A beautiful emerald green color is produced. Heller proposes this test for doubtful cases; He adds a little albumen to the urine, then drops in the HNOs which gives to the albumen the play of colors previously described. Pettenkofer’s test for the bile acids is the addition of a little strong H2 S04, drop by drop to a small quantity of the urine to which sugar has been added (one part sugar to four parts urine). The mixture is stirred with a glass rod, and first takes on a violet then a purple-red color. attended with severe and speedily fatal symptoms and constitutes, both by its own violence and the compli- cations which it determines, a disease of the utmost gravity. Hence we have three great divisions of jaundice, each of which demands different treatment; icterus without obstruction, icterus with obstruction, and grave icterus. But, do you ask me now, from a clinical point of view, how can we recognize these three varieties of jaundice? Nothing is more simple. In patients affected with jaundice, the faecal matters either contain bile and are colored, or they contain no bile and are colorless. In the latter case you have to do with icterus with obstruction, and in the former with icterus without obstruction. Does a case of jaundice present itself with a train of symptoms bespeaking a state of general constitutional infection ? i. e., with nervous, febrile or grave adynamic disturbances? You have before you, either a case of grave primary icterus, or a case of “ aggravated ” icterus, a variety of grave icterus be- longing properly to the terminal period of several attacks of hepatitis. Hence, as you see, nothing is easier than this diagnosis when once you have detected the passage of bilirubin into the blood and urine. It suffices to examine the stools and general symptoms to determine the kind of jaundice. Let us then examine the first of these groups, i. e., icterus by obstruction: the causes are subdivided into three groups. In the first group, the cause resides within the bile ducts themselves, as in biliary lithiasis, where the calculi obstruct more or less completely the excretory conduits, and determine an icterus which may be temporary or persistent. Besides biliary calculi, authors have also admitted an icterus caused by obstruction of the ducts, due to thickened bile (Murchison and Frerichs); to foreign bodies (Saunders); to lumbrici, to hydatids, to distomata. Jaundice may also be caused by a congenital absence or obliteration of the duct (fatal icterus of new born children); by a swelling of the bile ducts, due to perihepatitis; by an oblitera- tion of the orifice of the choledochus by reason ol an ulcer of the duodenum (Murchison); by cicatrices resulting from ulcers caused by presence of calculi, etc. Tumors within the bile duct may also cause obstruction, but ordinarily the compres- sion comes from tumors in the vicinity—tumors of the liver, cancers, hydatids, hypertrophied lymphatic glands, tumors of the stomach, of the pancreas, of the kidneys, etc., aneurisms, (Frerichs), the gravid uterus compressing the common bile duct, and ovarian or uterine tumors. In the second group, the cause of the icterus is in the walls of the bile ducts, as in catarrhal icterus, where the jaundice is determined by inflammation of the ductus choledochus, which produces swelling of the mucosa and the formation of mucus plugs which op- pose the passage of the bile. It is in the same group that authorities would place the so-called spasmodic icterus, i. e., icterus determined by contraction of the muscular tunic of the bile ducts, said to be at times sufficiently intense to prevent the excretion of the bile. But I utterly deny the existence of this spasmodic icterus, and al- though I fully believe in the possibility of spasm of the choledochus duct, my experiments have shown that this spasmodic action is never intense enough or persistent enough to be the cause of anything like prolonged arrest of the passage of the bile. Lastly, in the third group of jaundice by obstruc- tion the cause of the jaundice resides outside of the bile ducts. We have, in fact, to do with all kinds of tumors compressing these ducts and thus opposing the outflow of bile. I have just stated that whenever, from any cause, the bile does not flow into the intestine, jaundice ap- pears. There are several explanations of this fact. Some believe that the biliary secretion is suppressed by virtue of the obstruction. The liver, they say, simply separates the bile from the blood, and when this sep- aration does not take place, the bile accumulates in the blood and causes symptoms of jaundice. This theory, which is called the functional theory, is similar to that which is invoked in explanation of the uraemia which supervenes when the ureters are tied in an animal. But this interpretation which is quite ap- plicable to the kidney, is not applicable to the liver, because, as I have already told you in the previous lecture, the hepatic gland does not simply separate the materials of the bile from the blood, but forms de novo from that fluid the principal elements of this secretion. The second explanation is more physiological. It affirms that the bile when it accumulates in the ex- cretory ducts is absorbed and passes back into the blood. The experiments of Heidenhain, and especially of Picard, of Lyons, have in fact shown that very ac- tive absorption goes on in the mucous membrane of the bile ducts. I believe, then, that this latter theory, called theory of resorption, is the only one which ex- plains the facts now before us. But with what rapidity does this absorption of bile take place. The experiments which Audige and myself have undertaken have convinced us that the passage of bilirubin into the circulation is more rapid than is generally supposed. We have, in fact, shown that when you tie the common bile duct in a dog, and examine the urine, it is four hours after the ligature before the first traces of bilirubin appear in that excretion. This was the view which Saunders defended in 1795, but which has been in our time combated by Frerichs, who affirms that the passage of bile into the urine does not take place until at the end of from 18 to 30 hours.* * Frerichs, Treatise on Diseases of the Liver; Saunders, Treatise on the Liver; Dujardin-Beaumetz and Audige, loc. cit. Wickham Legg has made some experiments on cats in which he practised ligature of the bile ducts. He affirms What are the therapeutic indications in icterus by obstruction ? First, remove the obstacle if it be possible, and favor the flow of bile, then combat the symptoms which are due to this obstruction. To fulfil the first indication, we have already seen what must be done when the obstacle is a gall stone. What now should be the treatment when the obstacle is a mucous plug. In other words, what is the treatment of that most common form of jaundice, catarrhal jaundice ? This jaundice, bear in mind, is the result of an inflammation of the bile ducts, an in- flammation which is generally secondary, and the con- sequence of an irritation of the upper part of the in- testine (the duodenum). This mucous plug which obliterates the biliary conduits and thus explains the catarrhal jaundice, is not a matter of theory, a mere assumption, and Vulpian has demonstrated its un- doubted existence in animals. How will you treat that in this animal the icteric hue of the conjunctiva ap- pears but tardily. Most of the animals died in from two to twenty-nine days after ligature of the ducts. Two of the sur- viving animals were killed from twenty-seven to twenty-nine days after the operation, but in these cases the ducts were found not to be absolutely impervious, some bile still filter- ing through into the duodenum despite the ligature. In all these observations there was a notable augmentation of the connective tissue of the liver, although the hepatic cells seemed to be intact.* *Wickham Legg, on “ The Changes in the Liver which follow Ligature of the Bile Ducts,” St. Bartholomew’s Hospital Reports, 1873, page 161. this cholecystitis ? By hygienic means, on the one hand, and therapeutic means on the other. The hygienic means pertain principally to the dietary, and especially to milk diet. In fact, this gastro-duodenitis, which has brought about by con- tiguity and continuity of morbid action the chole- cystitis, is generally the result of a too excitant or too abundant diet. Our duty in these cases is to let the organ rest, but as this means if fully carried out is incompatible with life, you should advise the kind of food which is the least irritating. Recommend, then, to your patients to employ a milk diet exclusively. You may add alkalies and alkaline waters, which regulate the func- tions of nutrition, calm irritation of the primse viae, and favorably modify the hepatic circulation. Then, again, you should stimulate the biliary secretion, in order to endeavor to overcome the ob- stacle causing the jaundice. You may give podophyl- lin, euonymin, or calomel, drawing largely from the group of cholagogues of which. I gave you a descrip- tion in a former lecture. You will especially employ those which have a manifest purgative action, and for this reason, that the intestinal acholia, which is the result of the obliteration of the bile ducts, always en- tails more or less obstinate constipation. Make use, then, of the saline purgatives with a sodium sulphate basis, or the mineral waters, such as Carlsbad and Rubinat, which owe their activity prin- cipally to this salt. Employ also an excellent method prescribed by Krull, i.
