In the apepsia of infants, characterized by the presence of undigested aliment in the discharges, this combination is an excellent remedy. If a marked degree of acidity exists, the acid should be omitted, or given before the milk, when it may prevent the excessive production of acid. In irritative dyspepsia, when the pain and suffering are due to slow and imperfect digestion, lactic acid will often give great relief, either alone or combined with pepsin. Cases of acidity and heartburn are often quickly relieved by lactic acid given before meals. When the presence of an excess of the phosphates, uric acid, and the urates, and of oxalate of lime, in the urine, is due to imperfect digestion and faulty assimilation, as is frequently the case, lactic acid is serviceable. Dr. Deecke advocates the use of lactic acid in chronic cystitis, as a means of arresting the ammoniacal decomposition of the urine, a con- dition in which he holds it to be very effective. Lactic acid has been used with varying success in the treatment of diabetes. The object to be gained is the prevention of sugar formation from the starchy and other elements of the food. Dr. Foster reports some cases apparently decidedly benefited, and Dr. Ogle gives an ac- count of two cases in which no good results were attained. Cases have been lately reported in which the patients were improved by the use of lactic acid, but on the whole the utility of this agent in diabetes must be held to be as yet subjudice. Disappointment in the use of lactic acid is frequently experienced from the poor quality of the drug. 94 RESTORATIVE AGENTS. Authorities referred to above : Bricheteau, Dr. Felix.

Antagonists and Incompatibles. — Alkalies and their carbon- ates, salts of lime and lead. Synergists. — Bitters and tonics in general. Physiological Actions. — By assisting digestion and by correcting an abnormal condition of the alimentary mucous membrane, acids directly contribute to the blood-forming process, and indirectly, through the blood, to the construction of tissue, and the bettering, in general, of the bodily condition. The mineral acids grouped above agree in the general qualities of their actions, but differ in some particulars. They attack the living tissues with great energy, abstract the water, and combine with the potash, soda, and lime bases. In virtue of this affinity for water and this power of combination with bases, they cause destruc- tion of tissue and are called escharotics. Some of them are more powerful than others : thus, sulphuric and phosphoric acids pen- etrate more deeply than the others. Nitric acid stains the skin yel- low ; sulphuric acid carbonizes or blackens. Hence in cases of acci- dent, or when these acids are used with criminal intent, it is very ob- vious at a glance which has been taken or given : nitric acid making a yellow stain of the face, lips, and mouth, and sulphuric carbonizing or blackening those parts. In the stomach they produce the same ef- fects. When concentrated, they destroy the mucous membrane of the mouth, epiglottis, oesophagus, and stomach. The systemic effects are 96 RESTORATIVE AGENTS. those of the irritant and corrosive poisons. The appropriate rem- edies are chemical and mechanical : alkalies, magnesia, soda, lime, soap, to neutralize the acid ; and eggs, milk, oil, etc., to protect me- chanically the tissues. The depression of the powers of life which immediately follows the ingestion of a mineral acid should be treated by opium, nutrient and stimulating enemata, and the intra-venous in- jection of ammonia. The mineral acids, when administered in medicinal doses, must on reaching the stomach act in accordance with their chemical position. They will combine with the bases and form salts. Hydrochloric, and to a less degree phosphoric, aid digestion, acting as synergists to pep- sin, and contribute to the formation of peptones. Sulphuric unites with bases to form insoluble sulphates, and precipitates the albuminous sub- stances from their solution in the gastric juices ; hence this acid, although for a brief period it improves, soon disorders digestion. It is true of all the mineral acids that their long-continued use diminishes the production of acid gastric juice, and in this way after a time they cause the very troubles for the relief of which they were originally administered. An acid solution on one side of an animal membrane, and an alkaline solution on the other, is the condition most favorable to osmosis. Hence the introduction of an acid into the stomach with sufficient frequency and in sufficient quantity must impair the produc- tion of acid gastric juice. In practice this is found to be the case. The mineral acids are among the most diffusible substances known, and of these hydrochloric stands at the head. So much of these acids as does not enter into combination in the stomach diffuses quickly into the blood, and the salts which they form by combination with bases follow the laws of diffusion according to their class. The acids, es- pecially the hydrochloric, and next nitric, diminish the alkalinity of the blood, and in this way accomplish all that they are capable of doing as systemic remedies. Therapy. — Not much need be said of the use of the mineral acids in affections of the mouth and throat. Formerly they were much em- ployed in the treatment of mercurial and other forms of stomatitis, diphtheria, aphtha?, gangrene, etc. In using mineral acids in affections of the mouth, it should not be forgotten that they attack the enamel of the teeth. First, the animal matter adherent to the teeth is dissolved off, when the teeth are said to be " set on edge." The acid should be applied to the affected surface only, and the mouth should afterward be washed out with an alkaline lotion. Pure hydrochloric acid may be applied with a camel's-hair brush or on a bit of soft pine-wood to the gums in cases of sloughing from mercurial stomatitis, and to the ulcers of stomatitis materna, to syphi- litic mucous patches, and to those painful ulcers of the mouth which occur periodically in some subjects affected with a peculiar form of in- MINERAL ACIDS. 97 digestion. In the case of ulcers having their origin in stomach-dis- order, the internal use of hydrochloric, nitric, or nitro-muriatic acid, is often extremely beneficial. The local use of hydrochloric acid in diphtheria, so strongly urged by Bretonneau, is now rarely employed, for it is well known that the diphtheritic exudation will rapidly extend over an inflamed surface pro- duced by the application of the acid, and the destruction of the exu- dation at one part does not prevent its extension and renewed forma- tion. Any of the mineral acids administered by the stomach should be well diluted, and to prevent injury to the teeth should be taken through a glass tube or a straw. The mouth should also be rinsed out after swallowing the acid. The mineral acids are highly useful in certain stomach-diseases. In atonic dyspepsia hydrochloric acid should be given after meals, or better, lactic acid. It is highly probable that hydrochloric acid is produced during digestion by the reaction between chloride of sodium and lactic acid. A combination of the acid with pepsin, as already suggested, is preferable in these cases of atonic dyspepsia. When, in consequence of faulty digestion, acetic, lactic, and butyric acids are produced in the stomach from the starchy, saccharine, and fatty constituents of the food, the acids given after meals add to the distress of the patient. To prevent the excessive formation of acid, whether due to the ac- tion of the gastric glands, or to abnormal fermentation of the starchy, saccharine, and fatty elements of the food, mineral acids are used with decided advantage, but they must be administered before meals. For this purpose, hydrochloric or phosphoric acid is to be preferred. The excessive production of acid is manifested by acid eructations, pyrosis, heartburn, and idcerative stomatitis. There is a form of indigestion characterized by eructations of offen- sive gas, painful digestion, a sallow complexion, and by the appearance of oxalate-of-lime crystals in the urine, and is accompanied by mental despondency. This state of things is relieved by the nitro-muriatic acid ; sometimes better by nitric. The experience of English physicians practicing in India has been favorable to the use of nitro-muriatic acid in chronic hepatic affections, and in dysentery and dropsy of hepatic origin. Acute diseases of the liver, and such chronic affections as cirrhosis and waxy degeneration, are not as a rule benefited by the mineral acids. Mucous duodenitis and catarrh of the gall-ducts accompanied by jaundice, and jaundice of malarial origin, are forms of hepatic disease in which nitro-muri- atic acid is serviceable. With the internal use of the acid should be conjoined the local use to the right hypochondrium of the acid bath. Three ounces of nitro-muriatic acid to a gallon of water is a suitable strength for the topical use in this way. The feet may be placed in the 1 98 RESTORATIVE AGENTS. bath, and the legs, arms, and abdomen may be alternately sponged, when the skin is torpid and its secretion defective. The temperature of the bath should be about 96° Fahr. (Martin). Another mode of making topical application of the acid bath is as follows : " Let a flan- nel roller of ten or twelve inches wide, and sufficient to encircle the body twice, be soaked in the fluid and then wrung so as to remain only damp. Apply this instantly to the body, covering it with a piece of oiled-silk to avoid damping the dress. It should be worn constantly, but should be changed, soaked, and wrung, morning and evening" (Squire). This is a very effective local application in the hepatic dis- orders mentioned above as amenable to treatment by the mineral acids, and is serviceable in the first stage of cirrhosis. Dr. Scott, of Bom- bay, ascribes to the acid bath the power to relieve the pain of hepatic colic, by causing the expulsion of the impacted calculus. The mineral acids are very effective remedies in the treatment of summer and colliquative diarrhoea. Crapulous diarrhoea and dysen- tery are not benefited by them. The indications for their use are these: painless, watery evacuations, of a light color, alkaline in reaction. Hope's mixture, which contains nitrous acid, has long been used with success in such cases. The formula is as follows : $ Acidi nitrosi, 3 j ; tincturae opii, gtt. xl ; aquae camphorae, 1 viij. S. : One fourth to be taken every three or four hours. A mixture of this kind may readily be extemporized, in which the relative proportion of the acid and opium may be arranged according to the indications of the case. Sulphuric acid is more decidedly astringent than nitric and muriatic, and is, therefore, as a rule, to be preferred in diarrhoea. Bence Jones places them as regards their actions thus: Hydrochloric more promotes diges- tion; nitric acid, secretion; and sulphuric, astringency. Nitric and nitro- hydrochloric are, according to this view, better suited to stomach and hepatic disorders characterized by deficient secretion, and sulphuric is more appropriate for the relief of a relaxed state of the mucous mem- brane. A combination of aromatic sulphuric acid with opium is one of the most effective remedies we possess in the treatment of summer diar- rhoea and cholera. Sulphuric acid may also be used with advantage in the treatment of dysentery, in combination with sulphate of magnesia. 5 Magnesii sulphat., 1 j; acidi sulphur, dil., 3 ij; morphinae sulph., gr. j; aquae, 1 iv. M. S. : A tablespoonf ul every three or four hours. After the action of a saline laxative, Hope's mixture, or an extemporized prescrip- tion of a similar kind, may be used. When the mineral acids do not quickly improve the discharges and lessen their frequency, and when they increase the tormina and tenesmus, they should be suspended. In the treatment of cholera, dilute or aromatic sulphuric acid may be given frequently, well diluted, in full doses. Opium can be added at such intervals as may be indicated. MacCormac has found the acid to be a most valuable prophylactic against cholera attacks. It should be ad- MINERAL ACIDS. 99 ministered with promptness when the preliminary diarrhoea is threat- ened. Mineral acids, especially the muriatic, are very serviceable in fevers. They were formerly classed as refrigerants, or cooling medicines, and were supposed to allay thirst and to diminish fever. Although these notions are no longer entertained, the acids are known to render an im- portant service in fevers. They increase secretion of the mucous mem- brane, and thus relieve the dryness of the tongue and fauces. As in fevers the gastric juice is deficient in acids, digestion is materially aided by their administration. In typhoid fever, the acids restrain somewhat the exhausting diarrhoea, increase the digestive power, and remove or diminish the dryness of the tongue. It is probable that they exert an influence on the composition of the blood, beyond the increased activity which they impart to the primary assimilation. Hydrochloric acid is preferable in the treatment of fevers. It may often be advantageously administered in beef -juice. In scarlet fever, hydrochloric acid is frequently combined with chlorate of potassa (producing euchlorine), but it is better adminis- tered alone in this disease. Besides the internal administration of the acid, it is often mixed with water and used as a gargle, or mixed with honey and applied with a brush to the throat. One part of acid to five parts of honey or ten of water is a strong enough solution for this purpose. In the other eruptive fevers, hydrochloric acid is serv- iceable to allay thirst, to increase digestion, and to obviate the tend- ency to adynamia in these diseases/*To children, the dilute hydro- chloric acid may be readily administered in lemonade or in sirup of lemons. There is no doubt of the value of the acids, especially the nitro- muriatic, in the treatment of constitutional syphilis. This remedy is not to be compared in efficiency with mercury and iodide of po- tassium, but in chronic cases saturated, so to speak, with these ap- proved remedies, in which syphilitic patches persistently reappear in the mouth, nitro- muriatic acid often renders important service. It is undoubtedly true that constitutional syphilis has been treated successfully by the acids alone, but a very rigidly abstemious dietary has been enforced in these cases. It has already been shown that the denutrition method is of itself sufficient in some cases to relieve the organism of constitutional infection. How much of the result is to be ascribed to the remedy, and how much to denutrition, is not clear. Nitric acid has been used with success in the treatment of inter- mittent fever by Hammond, Bailey, and others. In order to obtain a curative effect, it is necessary to give the acid in full doses every four or six hours. This acid is of great service, also, after an arrest of the paroxysms of intermittent by quinine, to remove the hepatic congestion 100 RESTORATIVE AGENTS. and the changes in the glandular apparatus of the intestines induced by the fever-movement. It may be advantageously combined with the bitters, or used instead of the aromatic sulphuric acid in the prep- aration of the official infusum cinchonce flavce. The mineral acids have long been used with more or less advan- tage in the treatment of phthisis. Their utility obviously depends on the fact that they supply to the digestive fluids a material in which they are deficient in this disease. As Fenwick has shown, both pepsin and acid occur in quantity much less than normal in the gastric juice of phthisical subjects. The acid best suited for the treatment of the indigestion of phthisis is the official acidum mu- riaticum dilutum. Nitric acid is one of the numerous remedies used in whooping-cough. It is frequently successful in shortening the duration of the disease and moderating its violence ; but it acts much more beneficially after the subsidence of the catarrhal stage. It should be given well diluted in sweetened water. Chronic bronchitis and hoarseness produced by singing and by simple acute catarrh are relieved by ten-minim doses of dilute nitric acid. The mineral acids, especially the hydrochloric, have lately been proposed as remedies for acute rheumatism. The unquestionable util* ity of the tincture of the chloride of iron in rheumatism lends support to this practice. It is highly probable that the mineral acids check the formation of lactic acid inUhe blood. Whatever may be the na- ture of the action, good results irom the treatment have been reported (Dr. J. James Ridge). Some of the accidents due to lead are prevented, and relieved when they occur, by sulphuric acid. Sulphuric-acid lemonade is used by workmen in lead-factories to prevent lead-poisoning. This is supposed to act by forming the insoluble sulphate of lead. Dilute sulphuric acid is also effective in the treatment of lead-colic. The constipation due to lead is relieved by a combination of sulphuric acid and sulphate of magnesia, and the lead-cachexia is much benefited by a prescrip- tion of sulphate of quinine, sulphate of iron, and dilute sulphuric acid. The effects of lead on the nervous system are not removed by sul- phuric acid. Sulphuric acid is sometimes very effective in uterine hemorrhage. It has seemed to the author to be more useful in the case of haemor- rhage due to fibroid or polypus than the flow arising from other causes. Although sometimes prescribed for pulmonary hemorrhage, it is not equal to other remedies. In intestinal hemorrhage sulphuric acid acts directly in part, and is therefore serviceable. In purpura it sometimes acts happily. The aromatic sulphuric acid has long been used to check profuse sweating, especially the sweating of phthisis. It is certainly service- MINERAL ACIDS. 101 able in this condition, but objectionable because of the ill effects of the acid on the function of digestion. If used at all, it should not in any case be long continued. Nitric and nitro-hydrochloric acids have also been used with ad- vantage in such diseases of the skin as lepra, impetigo, acne, erythema nodosum, and others, in which the skin-affection is symptomatic of imperfect digestion and assimilation. In certain morbid states of the urine, as the phosphatic diathesis, oxaluria, alkalinity of the urine from disease of the urinary mucous membrane, and. phosphatic calculus, the mineral acids render important service. In chronic cystitis and phosphatic deposits, a very weak solu- tion of nitric acid (gtt. j — 1 j) may be injected with advantage. In using such injections it is to be remembered that the bladder is ex- tremely intolerant, and hence they should be permitted to escape im- mediately. When uric acid is in excess in the urine from faulty diges- tion and assimilation, hydrochloric acid is often of great service : the excess of uric acid disappears because the foods are more perfectly prepared for admission into the blood. Local or Topical Uses of the Mineral Acids. — Some allusions have been made to the local application of muriatic acid in diseases of the throat and of the acid bath in hepatic affections. It will not be necesary to recapitulate on these points. Nitric acid is one of the most efficient escharotics for the destruc- tion of specific or unhealthy ulcers. It is the most frequently used caustic for the destruction of chancroid, sloughing or phagedenic chancre. A glass rod or bit of pine is dipped into the acid and ap- plied, care being taken to penetrate to all the sinuosities of the sore. The surrounding healthy tissue may be protected from injury by the previous application of oil, and, when the acid has sufficiently pene- trated, its further action may be arrested by some alkaline wash. A water-dressing, or spirit and water, or dilute tincture of benzoin, or some similar application, may be afterward applied to the sore. Ordi- nary indurated chancre does not require escharotic applications. Hos- pital gangrene, or a gangrenous condition of wounds, injuries, or ulcers, is similarly treated with advantage, and probably no form of caustic is more desirable than nitric acid for these purposes. Ordinary torpid and ill-conditioned ulcers are improved and put in the way of healing by frequent washing with a weak lotion of nitric acid ( J j — Oj). The same solution will remove mucous patches and condylomata, and will often check the bleeding from haemorrhoids. Nitric acid is one of the means employed for the removal of hem- orrhoids. It is not effective, however, against all forms. Large haemorrhoids are much better treated by the ligature, galvano-caustic loop, or other radical measures. The so-called "strawberry-pile," a small hemorrhoid of red color, which consists of a congeries of arte- 102 RESTORATIVE AGENTS. rial twigs and which bleeds freely, can be effectually destroyed by nitric acid. The pile should be exposed, usually through a speculum, and the strong nitric acid be applied on a pine stick freely, followed by an abundant application of olive-oil to prevent the extension of the escharotic action to the surrounding parts. Small, superficial ncevi are treated successfully in the same way. Sulphuric acid penetrates more deeply than nitric, and its escha- rotic action is not so easily limited ; hence, it is not so frequently em- ployed for the destruction of sloughing and ill-conditioned ulcers. It is sometimes used in the form of Ricord's paste to chancres, sloughing or phagedenic. The paste is made by the addition of sufficient char- coal to strong sulphuric acid to give it the proper consistence. This is spread on a piece of muslin of a size equal to the sore, and is allowed to remain on until an eschar is produced, when an ordinary poultice may be applied. A favorite liniment of Sir Benjamin Brodie for counter-irritation of diseased joints is made by the addition of sulphuric acid to olive-oil ( 3 j of the acid, § iv of olive-oil). A general bath in, or sponging the body with, a solution of nitro- muriatic acid — one ounce to a gallon — is very serviceable in the case of cachectic children who present these symptoms : a dry and wrinkled skin, sallow complexion, capricious appetite with a taste for dirt-eat- ing, and whitish, pasty motions. Applying to the surface of the body an acid solution must affect the constitution of the blood, for an acid solution on one side of an animal membrane and an alkaline fluid on the other are the conditions most favorable to osmosis. Lately, Dr. Lombe Atthill, of Dublin, has called attention to the "use of nitric acid in the treatment of uterine disease." He applies the fuming nitric acid to the interior of the uterine cavity after pre- vious dilatation with sponge or laminaria tents. In order to protect the cervix and cervical canal he introduces an intra-uterine speculum with expansive blades. The cavity is first mopped out and dried with cot- ton ; then a probe, wrapped with cotton, is dipped in fuming nitric acid and applied thoroughly to the mucous membrane. This practice is very effective in the treatment of intra-mural fibroids and fungous granulations, to restrain hemorrhage, and after the removal of polypi. He almost invariably employs nitric acid in the treatment of granular cervicitis and endo- cervicitis, "with the best results." When decided tenderness of the uterus exists, he advises that this be first removed by suitable measures. Authorities referred to above : Atthill, Dr. Lombe.

Composition. — The above-mentioned oils and fats differ in the quantity of olein, stearin, and margarin which they respectively con- tain, and hence differ in physical qualities. Lard is composed of 38 per cent of stearin and margarin and 62 per cent of olein, and olive- oil of 72 per cent of olein and 28 per cent of margarin. The more solid fats, as suet, contain much stearin. These neutral fats are, chemically, combinations of an acid (stearic, palmitic, margaric, oleic) with a base, glycerin. The olein of linseed-oil appears to differ from ordinary olein by furnishing a different acid — linoleic — when saponi- fied. Oleum morrhuai. — Cod-liver oil. Huile de morue, Fr. ; JLeberthran, Ger. The fixed oil obtained from the fresh livers of Gadus morrhua and other species of Gadus. Composition. — Cod-liver oil contains a peculiar principle, gaduin, and yields, by distillation with ammonia, propylamin. It also differs from the fats and oils above described in containing various biliary 104 RESTORATIVE AGENTS. principles and traces of iodine, bromine, phosphorus, sulphuric and phosphoric acids, lime, magnesia, soda, and iron. It agrees with the other oils in being composed for the most part of olein and margarin. It is the latter constituent which gives the white cloudiness of cod-liver oil in cold weather, and which is, by the " British Pharmacopoeia," di- rected to be separated by artificial cooling. According to Winkler, cod-liver oil does not yield glycerin, but oxide of propyl, when sa- ponified. There are three varieties of oil, due, not to differences in composi- tion, but to modes of preparation : the pale, the light-brown, and the dark oil. The pale oil is freest from the products of decomposition and empyreuma, and is the best for internal administration. In order to obtain more positive therapeutical results, certain me- dicinal substances are frequently added artificially to the cod-liver oils of commerce. Iodine, bromine, phosphorus, and iron, are thus added. Not only are such compounds bad, chemically considered, but the addi- tion of such ingredients gives great opportunities for sophistication, and impure brown and other fish-oils may be substituted for the pure cod-liver oil. It has been supposed that any oil or fat, even glycerin, may be used in place of cod-liver oil, and cream has been prescribed in this belief. Linseed-oil has been considered to have some special efficacy in wasting diseases, more particularly in phthisis, because of the large amount of vegetable albumen which it contains. These notions are erroneous. Cod-liver oil has special therapeutical virtues because it contains gaduin, propylamin, the constituents of bile, iodine, phos- phorus, bromine, etc., in addition to the ordinary ingredients of an animal fat. Physiological Actions. — An oil or fat applied by friction to the epidermis will disappear, and, as a positive gain may thus accrue, it is reasonable to suppose that not only absorption, but assimilation, also, has taken place. Pat plays an important part in the metamorphosis of animal fluids. As was long since shown by Lehmann, a small quantity of fat is essen- tial to the digestion of nitrogenous articles of food. Cod-liver oil, as well as other oils, when taken in the proper quantity, has the power to facilitate gastric digestion, and therefore promotes the appetite. Oil is a very important material in intestinal digestion — constitutes the molecular basis of the chyle, which consists chiefly of finely-divided fatty matter, each globule of fat being surrounded by a thin layer of albumen. The fat taken in with the food undergoes the emulsionizing process, chiefly in the small intestine, and by the aid of the pancreatic and biliary secretions. Cod-liver oil is, above all other fats, adapted to form the molecular basis of the chyle. All fats do not penetrate into the veins and lacteals with the same facility, and the presence of OILS AND FATS. 105 certain substances is necessary to the process. Fats are not crystal- loidal but colloidal substances, and have, therefore, but a feeble power of osmosis ; but, notwithstanding this fact, the blood of the portal vein is much richer in fat than the blood of the arteries and systemic veins. The diffusion of fats is accomplished by the action of the bile. It was long since shown, by Wistinghausen, that in capillary tubes moistened by bile, oil will rise much higher than in tubes not so moist- ened, or when moistened with water or a saline solution. He also showed that oil will pass through membrane saturated with bile much more readily than through similar membrane saturated with water. It has been ascertained that, in dogs with biliary fistulse, the amount of fat in the chyle is much below the normal, and in the faeces much greater than normal (Day). Hence it must be concluded that the presence of bile is necessary to the absorption of fats, and that cod- liver oil must be peculiarly adapted to form the molecular basis of the chyle. It is for these reasons that, during a course of cod-liver oil, the body-weight is increased, the red blood-globules become more nu- merous, and a greater amount of fat is deposited in the tissues. It promotes the constructive metamorphosis. The important role per- formed by the oils and fats in the organism is shown by a variety of considerations. Wherever tissue-changes, physiological or pathologi- cal, are taking place, fat accumulates and enters largely into the for- mation of the resulting products. Newly-formed plasma contains much free fat, and all plastic exudations more than the non-plastic (Lehmann). Fat is the most abundant constituent of pus. Food is intended ultimately for two objects : first, to build up the tissues in the growing state and to reconstruct the tissues wasted by use ; second, to supply force, nervous, muscular, and digestive, to the different parts of the organism requiring it. The part performed by the fats is important as regards both objects. As already stated, they are essential to the construction of tissue ; modern researches have shown that they have a necessary office in the evolution of force. The well-known experiment of Fick and Wislicenus demonstrated that, on a diet of hydrocarbons, great muscular effort can be undergone with but little destruction of muscular tissue, and without increased urea- discharge. Turkish porters, who are remarkable for their great mus- cular strength and endurance, live on a diet composed of fat and rice. The acrobats of Japan, who live on a similar diet, grow to an enormous size, and accomplish feats of strength and agility to which the athletes of Western nations are hardly equal. If a muscle is made to contract under a bell-jar, an extraordinary evolution of carbonic-acid gas takes place, just as in violent muscular exercise the amount of carbonic-acid gas exhaled from the lungs is increased. Therapy. — Oils and fats are used by inunction in the treatment of 106 RESTORATIVE AGENTS. the scaly skin-diseases. In this case, the normal amount of oil in the skin being deficient, it is supplied artificially. Inunctions of oil or fat promote constructive metamorphosis in such chronic wasting diseases as phthisis, scrofula, chronic dysentery, etc. The best oil for this purpose is cod-liver oil, but, as it stains the skin yellow and has a disagreeable odor, it is often strongly objected to. Sevum or suet may be used, and may be perfumed to the taste of the patient. The best time for practicing the inunctions is just before re- tiring. A warm bath should first be taken, and then from one to two ounces may be rubbed into the skin. A thick night-garment should be put on to prevent injury to the bedding. Badly -nourished infants, rickety, or scrofulous, or suffering from chronic intestinal disorders, who have a dry and scaly skin, are often materially benefited by the tepid or warm bath, followed by inunctions of lard, suet, or almond-oil. Chlorotic girls, with or without disor- ders of menstruation, are improved in condition by the same means. Spare women, who wish to gain flesh and roundness of form, may have their wish gratified by warm baths and inunctions of oil. The im- provement which results from this practice is partly due to the general gain in bodily nutrition. Rubeola, scarlatina, roseola, erysipelas, and other febrile diseases, are benefited by oil inunctions. These applications are grateful to the patient ; they allay the burning heat of the skin, and in this way di- minish restlessness and excitement. It is said that inunctions of oil reduce the temperature, but the decline in fever-heat is probably the result of the calmative influence which these applications have over one of the chief sources of distress. Inunctions of oil have a special utility in the desquamative stage of scarlet fever. It is the author's observation that inunctions of oil are serviceable in fevers generally, when there is much heat of skin and high temperature, with restless- ness. Cocoa-butter is the most elegant of these preparations for ex- ternal use. In the infectious diseases, a little carbolic acid may be added to the inunction oil or fat, with the view of destroying disease- germs. Those who experience frequent catarrhal attacks, and take cold on slight exposure, may have their susceptibility diminished by a daily application of oil to the whole surface of the body. In many maladies, the patients experience a notable distaste for fatty food in any form. This is especially the case with scrofulous and phthisical subjects, and, as fat in some form is necessary to di- gestion, assimilation, and heat-producing, it is obvious that by the use of cod-liver oil an essential element of nutrition may be supplied in the best form. In cases in which there exists a condition of faulty as- similation of fats, cod-liver oil, by reason of the fact that it contains in intimate association the bile elements, is especially adapted to form OILS AND FATS. 107 the molecular basis of the chyle. In scrofula, rickets, and other dis- orders of the nutritive functions belonging to this group, cod-liver oil is the best agent for promoting constructive metamorphosis. After scarlet fever in many children, especially in those with stru- mous diathesis, there occur discharges from the nose and ears, feeble digestion, and general emaciation. These sequelce of scarlet fever are best removed by the internal use of cod-liver oil. As a remedy in phthisis, cod-liver oil holds the first place, but it is not adapted to all forms and all stages of that disease. It is especially a remedy for the chronic forms of phthisis— -fibroid lung and chronic tuberculosis — and is not serviceable in caseous pneumonia and acute phthisis. It is more useful in the chronic forms of phthisis because these afford the time and opportunity to reconstruct the tissues of the body — to build up the tissues from the molecular basis of the chyle. Cod-liver oil is not well borne when there is much fever, and can not be well assimilated when the stomach has undergone the alterations which belong to acute inflammatory affections. This remedy is too often prescribed without any reference to the condition of the pa- tient's digestive functions. The power of the stomach and intestines to digest fat is limited, and, if the quantity which can be disposed of is exceeded, the patient is incommoded. Rarely is it proper to pre- scribe more than a teaspoonful three times a day, and few patients can digest a tablespoonful. As the secretion of gastric juice, bile, and pancreatic juice, takes place most abundantly during the digestion of food, the time for the administration of oil in phthisical cases is after eating. When it is not well borne, the digestion and assimilation of the oil may be aided by combining it with liquor potassae, lime-water, the compound tincture of gentian, tincture of nux vomica, or strychnine, or other correctives according to the indications in individual cases. When the oil is not well digested — although stomach disorder may not have occurred — and it is seen to float on the stools, it may be com- bined with ether, since Bernard has demonstrated that ether increases the production of pancreatic fluid. If continued for a sufficient length of time, cod-liver oil is of the greatest service in chronic bronchitis and emphysema. It should be given in the same way and under the same conditions as in phthisis. Chronic rheumatism and rheumatic arthritis, maladies for the re- lief of which cod-liver oil was first prescribed, when occurring under bad hygienic influences in cachectic subjects, may be much relieved by this agent. In addition to the internal use of the oil, it may be applied with advantage locally to the affected joints. This combined use of the oil, systemically and by local inunction, is to be commended in the so-called rheumatic gout with deposits about the joints. On the same principle, cod-liver oil is beneficial in cases of strumous syno- vitis, caries, and necrosis of bone dependent on a constitutional state. 108 RESTORATIVE AGENTS. It does not have, it must be admitted, any direct influence over these morbid processes ; but it enters most usefully into constructive tissue- metamorphosis. As a reconstituent, cod-liver oil is a very useful remedy in certain chronic affections of the brain and nervous system. One of the most common conditions with which we have to deal in middle and ad- vanced life, and also one of the most important as regards the integ- rity of the brain, is atheroma of the arteries. This condition is rep- resented by increased hardness of the radial pulse, the arcus senilis, irregular action of the heart, giddiness, vertigo, partial loss of vision, and failure of the memory and other intellectual faculties. Used to obviate these degenerative changes, and to prevent failure in the nu- trition of the brain, we have in cod-liver oil a remedy of real value. It should be given in small quantity, and continued for a long time. As a phosphorized fat plays an important part in the structure and functions of the cerebral tissues, we may imitate the processes of Na- ture and administer the phosphates, the hypophosphites, or the lacto- phosphate of lime, in combination with cod-liver oil. The author has seen excellent results from such a combined use of these agents. Dr. Anstie much insists on the use of fats, especially cod-liver oil, as a part of the diet of those suffering from neuralgia, paralysis agitans, epilepsy, mercurial tremor, and chorea. Dr. Radcliffe had previously pointed out the utility of fats and oils in the same affections, and all practical physicians familiar with the subject are now pretty well agreed as to the value of this practice. The special indications for cod-liver oil in these affections are faulty assimilation and a low con- dition of the nutritive functions. Fats and oils are, of course, contra- indicated in these nervous disorders when they occur in plethoric and overfed subjects, but such a state of things is exceptional. In diseases of the skin of strumous origin, cod-liver oil is, as Dr. Tilbury Fox remarks, " our sheet-anchor." Among these diseases are lupus, ecthyma, psoriasis, scleroderma, etc. The constitutional state requiring cod-liver oil is a lowered condition of the assimilative func- tions dependent on the strumous cachexia. The local use of the oil is certainly advantageous in these cases. Dr. Hughes Bennett strongly recommends the free application of the oil to favus and eczema im- petiginodes. The condition of debility and faulty assimilation which results from the prolonged treatment of syphilis with mercury and iodine is frequently remarkably improved by cod-liver oil. The syphilodermata, when occurring in cachectic subjects, are benefited by a persistent use of the same remedy. "With the internal use of the oil may be con- joined inunctions. These are especially beneficial in the squamoe of syphilitic origin. Mode of Administration of Cod-Liver Oil. — As cod-liver oil is OILS AND FATS. 109 extremely repugnant to many patients, it is desirable to prescribe it in as agreeable a form as possible. Washing out the mouth with raw whisky or brandy so far blunts the sensibility of the nerves as to per- mit the oil to be swallowed without difficulty as regards its taste. Quickly stirred up in a hot whisky-punch, it may be swallowed with- out appreciation of the taste of the oil. It may be taken on beer, the oil covered with the foam, and carefully prevented touching the glass. A wine-glass may be thoroughly moistened with ale or beer, and the dose of oil just enveloped in the beer, when it may be tossed into the throat without perceiving the taste of the oil ; or the oil may be taken in sufficient lemon-juice in the same way. It may also be taken in black coffee. A very good disguise is that of Carlo Paresi, by which it is made to have the odor and taste of coffee. To 400 parts of cod- liver oil are added 10 parts of animal charcoal and 20 parts of ground roasted coffee. The mixture is digested in a water-bath at a tempera- ture of 50° to 60° C, and after standing three days is filtered and put in well-stoppered bottles. It is said that 10 drops of chloroform to 100 grammes of the oil will render it palatable. One part of essential oil of eucalyptus to 100 parts of pale oil makes a mixture in which the odor and taste of the oil are entirely extinguished. Two drachms of cod-liver oil may be mixed with a drachm each of compound spirits of lavender and brandy. Emulsions of cod-liver oil are now prepared with glycerin and yolks of eggs, and suitably flavored. The various emulsions with lime are also much prescribed. Cod-liver oil saponified by lime has been brought forward by Prof. Yan den Court, of Brus- sels, as a remedy of especial efficacy in phthisis. Lastly, cod-liver oil has been used instead of lard or butter in the preparation of rolls, which are readily eaten by children. The addition of ether to cod- liver oil promotes its digestion. Bernard long ago made the observa- tion that ether stimulates the pancreas and increases its secretion, thus contributing to the emulsionizing of the fats. The combination of ether and cod-liver oil has been especially urged by Dr. B. Foster. The committee of the New York Therapeutical Society report that the ad- dition of fifteen minims of ether to each half-ounce of oil enables the patient to take it, if it had previously disagreed.

Phosphorus. — Phosphore, Fr. ; Phosphor, Ger. A translucent, nearly colorless solid, resembling wax, without taste, but having a pe- culiar smell. Its specific gravity is 1*8. Oleum Phosphoratum. — Phosphorated oil. Prepared by dissolv- ing phosphorus in ether and almond-oil. One part of phosphorus to 100 parts of the menstruum. Dose, Hii — tt^v. Pilulce Phosphori. — Phosphorus pills. Each pill contains about yi-g- grain. Phosphorus is dissolved in chloroform, and then mixed with powdered althea and acacia, glycerin, and water. The pills are coated with balsam of tolu. Tinctura Phozphori (not official). — Phosphorus, one grain ; absolute alcohol, five drachms ; glycerin, one ounce and a half ; spirit of wine, two drachms ; spirit of peppermint, two scruples. "Dissolve the phosphorus in the alcohol with a little heat ; at the same time warm the spirit and glycerin together. Mix the two solutions while hot, and add the spirit of peppermint on cooling. Dose, one half to one drachm." Tinctura Phosphori JEtherealis (not official). — Solution of phos- phorus in ether. Dose, five to ten drops in sirup. A solution of phos- phorus in chloroform, or bisulphide of carbon, may also be prepared for internal administration. Pills of phosphorus may be extempo- raneously made by mixing the bisulphide of carbon solution with some inert powder. The evaporation of the bisulphide leaves the phosphorus in a finely-divided state intimately incorporated with the powder. Zinci Phosphidum. — Phosphide of zinc. Dose, one twentieth to one tenth of a grain. It is best administered in pill-form made with conserve of roses. Synergists. — Oils and fats favor the absorption of phosphorus, and should never, therefore, be employed in cases of poisoning by this agent. Arsenic, and in a feeble degree sulphur, are synergistic. Antagonists. — The chief chemical antidotes to phosphorus are hydrated magnesia, lime-water, powdered charcoal, and sulphate of copper. To this list must be added turpentine of a certain kind. Phosphorus is now frequently taken in the form of matches, the par- ticles of which do not readily dissolve in the stomach and intestinal juices. When pure phosphorus, in the sticks or cylinders in which it PHOSPHORUS. HI occurs in commerce, is swallowed, large masses may remain imbedded in the folds of mucous membrane, or, escaping solution, descend with the other contents of the canal. Considerable time may thus elapse from the ingestion of the poison until its action begins. Emetics, therefore, assume a high degree of importance, and the most service- able emetic is sulphate of copper, which is at the same time a chemical antidote (Eulenburg and Guttmann). Bamberger has shown that phosphorus reduces sulphate of copper to the metallic state, the first step in the process being the formation of phosphide of copper, and that the masses of phosphorus are surrounded by a layer of copper, preventing its evaporation. He therefore advises that an emetic dose of sulphate of copper be first administered. Emesis may be facilitated by giving hydrated magnesia, diffused in a quantity of tepid water. As catharsis is next in importance, the bowels should be thoroughly evacuated. After the emetic dose of sulphate of copper has acted efficiently, this antidote should be given in small doses as frequently as possible — about one twelfth of a grain every twenty minutes. As the irritability of the stomach may prevent sufficient retention of the sulphate, the carbonate of copper has been proposed as a substitute, although Eulenburg and Landois, in their experiments on animals, have been unable, by the exhibition of the latter, to prevent death in cases of phosphorus-poisoning. Unquestionably the most important chemical antidote is turpentine, the French acid turpentine, especially. Letheby was the first to note that the vapor of turpentine prevented the toxic action of the vapor of phosphorus, and that workmen employed in the match-factory at Stafford, who were protected by vials of turpentine worn about the neck, escaped necrosis of the maxillary bones and other deleterious effects. Dr. P. C. Andant next published cases indicating the anti- dotal power of turpentine, and M. Personne submitted the subject to experimental demonstration and confirmed the observations of Andant. As turpentine destroys the luminosity in the dark and arrests the es- cape of the vapor of phosphorus, M. Personne infers that it acts simi- larly as an antidote, that is, prevents the combustion of phosphorus in the blood and the consequent consumption of the oxygen. The author has collected forty-six cases of poisoning by phosphorus, in which tur- pentine was employed as the antidote, and of this number but four were unsuccessful (Kohler, Sorbets, Laboulbene, Schimpff, Lichten- stein, Rommeleare, Berthold, etc.). Rectified oil of turpentine is not antidotal. The acid French oil is the preparation which has been used with success. The experiments of Yetter on animals fully con- firm the results of clinical experience, for he found that, while the rectified oil of turpentine had no effect, the crude, acid, French tur- pentine was very efficient as an antidote. The action of the crude turpentine is a process of oxidation and combination by which phos- 112 RESTORATIVE AGENTS. phorus is converted into phosphoro-terebinthinic acid — a spermaceti- like substance, without poisonous or irritating qualities, which is elim- inated by the kidneys, the urine having a camphoraceous instead of the violet odor due to turpentine itself. Although the crude French oil is to be preferred, it is probable that our common oil of turpentine, exposed to the air, will develop antidotal power, by absorbing and ozonizing oxygen. The vapor of turpentine acts in the same manner on the vapor of phosphorus. The change in the effects of phosphorus acted on by turpentine has been thoroughly worked out. Adminis- tered to dogs, from one to fifteen grains, this substance excited no nausea, did not impair the appetite, caused no change in the tissues, and was eliminated harmlessly by the kidneys. To sum up : In the treatment of poisoning by phosphorus, in any of the forms in which it is introduced into the stomach, an emetic of sulphate of copper should be promptly employed, and the bowels should be moved by hydrated magnesia. When the stomach is emp- tied, small doses of sulphate of copper may be administered, but pref- erably turpentine, which should be given as rapidly as possible in an emulsion of gum, carefully avoiding oil. To counteract the cardiac and general systemic depression, opium will become necessary. If phosphorus has entered the blood despite the use of the appropriate antidotes, and much injury to its corpuscular elements has resulted, transfusion can be employed with considerable confidence, since Jur- gensen has succeeded in several instances in saving life by this ex- pedient. Direct transfusion of human blood, with or without previous withdrawal of some portion of the damaged blood, is the proper pro- cedure. Physiological Actions. — The vapor of phosphorus is highly irri- tating to the conjunctiva and to the broncho-pulmonary mucous mem- brane. If caries of the teeth exist, necrosis of the maxillary bones may be induced by the vapor ; but it is doubtful whether, as has been aflirrned, such necrosis may occur when the teeth are perfectly sound. There is an obvious distinction between the local effects of the vapor of phosphorus and the disease of the osseous system, the result of the constitutional impression of this agent. In ordinary medicinal doses, phosphorus gives rise to a sense of warmth at the epigastrium, but, if the dose be large, decided heat and even burning are experienced, and tenderness of the epigastrium re- mains. Prolonged administration of full doses will excite considerable gastric disturbance, and a catarrhal state of the mucous membrane. In the process of the oxidation of phosphorus, hydrogen is evolved, which in its nascent state readily combines with a portion of phosphorus, forming phosphide of hydrogen, eructations of which constitute one of the disagreeable features in the administration of this remedy. The action of the heart becomes more frequent, and the cutaneous circu- PHOSPHORUS. 113 lation, especially, more rapid ; the body temperature rises somewhat ; the mental activity and the muscular power increase ; the menstrual flow grows more abundant, and in males aphrodisiac effects are experi- enced, and the urine and sweat are more abundantly excreted. Phos- phorus promotes the constructive metamorphosis ; it increases the activity of the organs of vegetative life, and is a natural excitant of the functions of animal life ; it enters largely into the formation of tissues, and is a necessary element in the phosphorized fat which holds an important position in the composition of the cerebral matter. The administration of phosphorus increases the excretion of urinary phos- phates. The effects of phosphorus in toxic doses have been elaborately stud- ied, both in fatal cases of poisoning, occurring in man, and by experi- ments on animals. The form in which it is swallowed affects the rate at which the action occurs. If taken in solution in oil, in ether, or in the paste used as a vermin-destroyer, the toxic symptoms appear more promptly than if match-heads or ordinary phosphorus has been swal- lowed. An interval of varying duration elapses from the ingestion of the poison until disturbance of the stomach ensues. This interval — one to three hours — is occupied by the solution and oxidation of the phosphorus. Then epigastric uneasiness, nausea, and vomiting, come on ; first, the contents of the stomach, and then mucus and bilious mat- ters being ejected. The vomiting, accompanied by considerable epi- gastric pain and tenderness, persists usually for several days, when it assumes a special character, owing to the presence of the so-called "coffee-grounds," or " black- vomit." At first the vomited matters have a distinct odor of phosphorus, and appear phosphorescent in the dark. After several days of vomiting these symptoms disappear, and there may then be more or less hsematemesis, as well as coffee-grounds, due to erosions of the mucous membrane (Wolfe). The condition of the intestines varies with the presence or absence of phosphorus in their contents. The stools may be simply pasty and grayish from the absence of bile, or they may contain mucus and blood, and appear phosphorescent in the dark. Accordingly, as they may or may not be irritated, will the symptoms be those of constipation, diarrhoea, or dys- entery. The very characteristic but not invariable symptom — jaundice — appears on the second to the fifth day after the reception of the poison. It is absent in one fourth of the cases, and may be absent, also, when there is considerable fatty degeneration of the liver (Wolfe, Alter). It presents the usual appearance of jaundice as it occurs in acute yellow atrophy. It does not attain the maximum at once, but it appears first as some yellowness of the conjunctiva, the urine also becoming dark and loaded with urates, at the same time. The chemical changes which phosphorus undergoes in the stomach, and the combinations by which it enters the blood, are as yet not fully 114 RESTORATIVE AGENTS. explicable. That some phosphoric acid and phosphide of hydrogen are formed is certain. That the oil or fat in the stomach will dissolve some portion of the phosphorus, and thus facilitate its diffusion as phosphorus into the blood, is highly probable (Husemann and Marme). Phosphorus is also slightly soluble in water at about 100° Fahr., and in organic fluids, as the bile, to a greater extent (Hartmann). As in the oxidation of phosphorus, phosphorous and phosphoric acids, and phosphide of hydrogen, are products, it is certain that these exert a poisonous influence to a greater or less extent in the stomach (Lecor- che). A portion of the agent taken undoubtedly enters the blood as phosphorus, and the subsequent changes in tissue-metamorphosis are due to its presence in the blood, where it has been detected by Bam- berger and others. With the entrance of the poison into the blood the action of the heart increases, and the temperature rises, the fever having a remittent type (Mannkopff). Toward the end, however, the function of haematosis and of tissue-metamorphosis are so depressed that the body -heat declines below normal. In other cases there is no fever at all, or it appears near the end. Very great weakness of the heart's action has usually been observed, and the pulse has been much accelerated, although in some instances it became very slow, descend- ing as low as 40. The damage done to the blood is shown in the haemorrhages which take place from the various mucous surfaces — from the nose, stomach, intestines, kidneys, uterus (menorrhagia and me- trorrhagia) — and into the areolar tissue, in the form of petechiae and ecchymoses. A haemorrhagic diathesis develops, so that the bleeding from a simple wound, a leech-bite, etc., may become uncontrollable. The intellect may remain unimpaired, but usually there are restless- ness, with coma, sometimes noisy delirium, anaesthesia of the extremi- ties, paresis of the members, and, near the end, convulsions (Hermann). The poison entering the blood is eliminated chiefly by the kidneys. The changes occurring in the urine are of especial interest. No depart- ure from the normal occurs until the alterations in the composition of the blood, and the general steatosis, prepare the way. The urine is diminished in amount, contains albumen, blood, and sometimes fibrin- ous casts. When jaundice comes on, its appearance is first announced by the presence of bile-pigments and acids. Urea almost entirely dis- appears toward the fatal termination ; leucin and tyrosin are occa- sionally present, and a peptone-like substance ; but the peculiarity most distinctive is the large quantity of paralactic acid, especially in the fatal cases (Schultzen and Biess). The duration of the cases of phosphorus-poisoning is by no means uniform. Although the rule is that symptoms do not follow immedi- ately on the entrance of the poison into the stomach, there are cases in which pain, nausea, and vomiting do occur almost immediately, and ,the most formidable symptoms come on promptly. One case is re- PHOSPHORUS. 115 ported in which death occurred within nine hours, and numerous cases have terminated in death at the expiration of forty-eight to seventy- two hours. But usually the cases are less acute, and death does not occur before the end of the first, second, or third week. It is impor- tant to bear in mind that death may take place unexpectedly, before the most severe symptoms manifest themselves (Naunyn) ; and that the absence of decided gastric disturbance does not necessarily in- dicate a mild case. When recovery takes place, the improvement is slow, and the duration more or less protracted. In cases observed by Schultzen, the swelling of the liver could be distinguished at the ex- piration of four weeks, although the jaundice and the haemorrhages had disappeared. The changes induced by phosphorus are eminently characteristic. In the stomach are found erosions of variable extent, often absent ; fatty degeneration of the epithelium ; and a gastro-adenitis, first de- scribed by Virchow, and confirmed by subsequent observers, notably by Bernhardt, whence the membrane has a swollen, grayish, or yellow- ish color. The same state of the mucous membrane may exist in the intestine as well. The liver is much enlarged as a rule, but may be atrophied. In five of the sixteen cases studied by Wolfe the liver was atrophied, but this is probably a more advanced change, and is, there- fore, encountered in the most protracted cases. The color of the liver is usually a pale yellow, or it may present a deep yellow, the acini ap- pearing enlarged and distinct. The increased size of the organ, and the change in its appearance, are due to fatty degeneration of the he- patic cells and epithelium (Mannkopff) ; but, according to some other authorities, an interstitial hepatitis is also set up, which is especially well marked in chronic phosphorus-poisoning. The jaundice, it is agreed generally, is due to resorption of the bile, swelling of the bile- ducts and of the orifice of the ductus communis preventing the en- trance of the bile into the intestine. The presence of bile-pigments and acids in the urine supports this view, but it has also been main- tained that the jaundice is hematogenic from dissolution of the blood. The changes in the composition of the blood are numerous and im- portant : it is fluid, non-coagulable, its corpuscles altered in form, and it contains much fat (Mehu). There are numerous ecchymoses, es- pecially under the peri- and endo-cardium (noted in thirteen out of six- teen cases by Wolfe), under the capsule of the liver, and in other situations. Besides the alterations in the blood, the occurrence of ecchymoses is favored by fatty degeneration of the small blood-vessels and capillaries (Klebs). The heart is also the seat of an acute fatty degeneration, and its tissue is soft and easily torn. The spleen is en- larged, and the kidneys are also enlarged and fatty, the renal epithe- lium being crowded with oil-drops. 116 RESTORATIVE AGENTS. Not every case exhibits the wide- spread changes above described. If death occur in a short time, within nine hours, as has been noted, not sufficient time will have elapsed to allow of universal steatosis. There may, indeed, be no characteristic morbid appearances under such circumstances. In other cases, the changes may be limited to the liver. Chronic poisoning by phosphorus presents some interesting features. It occurs in those who are exposed to the vapor, in workmen engaged in phosphorus-factories, and especially in the workers in match-facto- ries. Irritation of the bronchial mucous membrane, and to a less ex- tent of the gastro-intestinal, takes place, with the attendant symptoms of cough, loss of appetite, indigestion, constipation, failure of nutri- tion, etc. The most important change is that occurring in the maxilla, more especially in the inferior maxilla, which is both more severely and more frequently diseased. The lower jaw has been repeatedly re- moved for this phosphorus necrosis, which begins in carious teeth, develops into a periostitis, and ends in death of the bone. The alve- olar process only, or a part or the whole of the bone, may be cast off. Phosphorus increases the production of osseous tissue ; the spongy tissue is thickened, and the compact is rendered more dense. Exten- sive osteophytic formations take place in animals fed on it, and the marrow cavity of long bones may be much encroached on, even closed, by the deposit of new osseous material (Wegner). Therapy. — The author enjoins on his readers the necessity for caution in the use of phosphorus. As this agent so readily induces an acute fatty degeneration, when taken in poisonous quantity, the pro- priety of its administration in large doses for long periods may well be questioned. Phosphorus, occupying an important position as an agent utilized in the constructive metamorphosis, may properly be prescribed when the nutritive functions are deficient in activity. It is especially in nutritive failure of the osseous and nervous tissue that phosphorus is required. The original suggestion by Wegner of its probable utility in osteomalacia, or softening of bones, has been acted on by Friese, who found it remarkably beneficial in some obstinate cases. It will prove useful, also, when this condition exists in rickets. That hitherto incurable malady — progressive pernicious anamiia — has in some in- stances been apparently arrested by the administration of phosphorus ; but it has failed in others. Further investigations are needed. The physiological action of phosphorus in small doses in increasing mental activity finds a therapeutical expression in the use of its prep- arations in cerebral disorders. It is indicated in pathological states dependent on anaemia, and contraindicated in vascular congestion and excitement. Cases of wakefulness, dependent on cerebral anaemia and exhaustion, are often remarkably benefited by phosphorus in the form of the pill or tincture. It does not procure sleep in the way that PHOSPHORUS. 117 chloral and bromide of potassium do. By the use of it in suitable states we supply to the cerebral substance a material which it requires for the healthy performance of its functions. It acts most beneficially in the cases of wakefulness in which the nutritive functions of the body are wanting in activity. The wakefulness of the aged, accom- panied with muscular cramps, feebleness of memory, giddiness, and trembling of the voluntary muscles on exertion, is improved by the preparations of phosphorus. Early decay of the mental powers, asso- ciated with atheromatous changes of the cerebral vessels, and conse- quent impaired nutrition of the brain, is benefited by minute doses of this agent. In these states, occurring in the aged, it is better to com- bine with the phosphorus, or to administer simultaneously, cod-liver oil. The author has seen good results from such a combination in paralysis agitans. Large doses of the medicine in these disorders of advanced life are improper and unsafe. The best results are obtained from the persistent use of minute doses. M. Delpech has obtained excellent results from the use of phosphorus in paralysis. It is ob- viously adapted to cases of chronic character in which all acute symp- toms have subsided. The paralytic symptoms which accompany white softening of the brain (local and circumscribed anaemia) have appeared to the author to be improved by the use of the phosphates, hypophos- phites, and lacto-phosphate of lime. The preparations of phosphorus are very serviceable in neuralgia. It is true Dr. Anstie, in his recent able work on neuralgia, expresses the opinion that " its utility is not very extensive or reliable." Rad- cliffe, Bradley, Broadbent, Mr. J. Ashburton Thompson, on the other hand, report cures in some obstinate cases. Mr. Thompson's experi- ence indicates that large doses are necessary to effect a cure. In his own words : " I now invariably begin by giving ^ of a grain every four hours, and this I conclude to be an average dose." The formula given under the title " Tinctura Phosphori " is Mr. Thompson's ; each drachm of it contains ^ of a grain of phosphorus. With this solution he has treated successfully thirteen cases of neuralgia. Dr. Broadbent has given phosphorus with advantage in " epileptiform vertigo," neu- ralgia, and "nervous breakdown from overwork." We have no remedy at present more efficient in the treatment of impotence than phosphorus. In the physiological state, priapism is one of the results of its toxic action. It is, of course, adapted only to cases functional in character, and not to impotence from organic de- fect. According to Dujardin-Beaumetz, phosphorus is useful in that very protracted and troublesome disease, progressive locomotor ataxia, or posterior spinal sclerosis. Although the author has not observed any instances of cure of this affection by phosphorus, he has witnessed in a few instances decided amelioration. 118 RESTORATIVE AGENTS. Phosphorus has lately been employed as a substitute for arsenic in the skin-diseases for which the latter is used — notably acne, psoriasis, lupus. The author has seen excellent results from the use of the com- pound sirup of the hypophosphites in acne indurata. Authorities referred to in this article : Alter, "W".

Physiological Actions. — In the first edition of this work the phosphates were included in the same section with phosphorus. There is a strong argument in favor of this arrangement, based on the chem- ical reactions which ensue when phosphorus is introduced into the stomach. Phosphorus has a strong affinity for oxygen, and compounds are quickly formed in the stomach. It is probable, however, that some phosphorus enters the blood uncombined. It is certain that the effects 120 RESTORATIVE AGENTS. of phosphorus differ in character from the effects of any of its com- pounds. They agree in the property of aiding constructive metamor- phosis, but differ widely in other respects. Physiological Actions of Phosphate of Lime. — There is no part of the body which does not contain, or does not yield on incinera- tion, phosphate of lime. It gives solidity to the osseous framework of the body, and, when too little is furnished during the growing period, rickets and mollities ossium are the result. The demand made on the system of the mother for the supply of this essential material for the growth of the osseous structure of the foetus is so great that her frac- tured bones unite with difficulty. The bones of animals, fed on food deficient in phosphate of lime, soften. All the animal fluids contain this substance in solution : thus it is found in the blood, the saliva, the gastric juice, milk, urine, and in the intercellular fluid throughout the body. It accumulates wherever tissue-changes are rapidly taking place (Dusart). It is obviously very important to the nutritive j^rocesses of the body. As phosphate of lime is to a limited extent soluble in lactic and hydrochloric acids, it is evident that, administered by the stomach, diffusion into the blood must occur. Large amounts can not, however, be disposed of in this way ; hence small doses must be as effective, in the treatment of the maladies for which it is prescribed, as large ones — for all in excess of the quantity soluble in the free acids of the stomach must pass off with the faeces or form intestinal concretions. Physiological Actions of Phosphate of Sodium. — This salt is soluble in water in the proportion of four per cent. Hence it may be given in solution, and will readily diffuse through into the blood. In the dose of one ounce it acts as a laxative. As it has a saline taste similar to common salt, it may be given in soup or other food. It in- creases the alkalinity of the blood, according to Bocker, by causing a retention of the chloride of sodium. Phosphate of soda diminishes the excretion of urea, in part, it is supposed, by hindering the retrograde metamorphosis of tissue, in part by its interference with the process of digestion. It is a constituent of the blood in the normal state, and as it possesses the remarkable property of increasing the quantity of car- bonic acid which can be held in solution by any liquid, obviously we have in these facts an explanation of its influence over the excretion of urea. That it impairs digestion in large doses when administered in health may be admitted, but by removing morbid states of the mu- cous membrane the digestive function, in suitable cases, is directly promoted by its use, and the nutrition of the body generally, and the tone of the nervous system, improved. Therapy. — In cases of the so-called bilious sick-headache, phosphate of soda is a most useful laxative. A permanent cure of this very troublesome malady may be wrought by regulation of the diet, and by PHOSPHITES AND PHOSPHATES. 121 the long-continued use of this remedy. It is not pretended that cases of migraine, due to an affection of the nucleus of the fifth, may be thus cured. A large proportion of these cases are produced by a catarrhal state of the gastro-intestinal mucous membrane, which the phosphate of soda has the power to remove. For the same reason, it is a remedy of the highest utility in cases of jaundice dependent on catarrh of the bile-ducts, this disease being secondary to the same process in the in- testinal mucous membrane. In these affections the phosphate of soda should be administered in a drachm dose (about one teaspoonf ul) three times a day, or more frequently. Children, who are frequently sub- jects of this disorder, do not require larger doses than ten grains to a scruple. In preventing inspissation of the bile and crystallization of cholesterin, and attacks of hepatic colic, the persistent use of the phos- phate of soda is rarely unsuccessful. It is not pretended that this agent can relieve the attacks of hepatic colic, and, indeed, it is useless at these times. Many cases of this disease, if not most of them, origi- nate in a catarrh of the duodenum, the transference of the catarrhal state by continuity of tissue to the gall-bladder, and the formation of a nucleus of mucus and bile, about which the cholesterin crystallizes. Phosphate of soda has the property to prevent the occurrence of these changes, and consequently to prevent attacks of hepatic colic. The author has found one scruple to drachm doses, administered for several months before each meal, extremely efficacious in a number of cases of this kind. The value of Yichy in this and kindred affections probably depends on the phosphate of soda contained in this mineral water. Many ill-conditioned children are found to pass pasty and white stools, showing the absence of bile, and are pale and ill-nourished not- withstanding an abundant supply of milk and a vigorous appetite. Ten grains of phosphate of soda, dissolved in the milk and given them several times each day, will often improve the intestinal di- gestion, change the appearance of the stools, and increase the nu- trition of the body. The phosphates are especially useful in diseases characterized by mal-nutrition. In rickets, mollities ossium, delayed union of fractures, early decay of the teeth in children, caries and necrosis of bone, in which the phosphate is needed to the repair and growth of the osseous structures, it may be supplied artificially. The phosphate of lime may be administered alone in these states, but is to be preferred in the form of the sirup of the lacto-phosphate, or of Parrish's phosphates. As a large consumption of the phosphate of lime takes place during suckling, the anaimia of the nursing mother may be most advan- tageously treated with the lacto-phosphate of lime or phosphates. The waste caused by suppuration, carbuncles, mammary abscesses or boils, may be best repaired by the same means. The constitutional 122 RESTORATIVE AGENTS. cachexia produced by chronic bronchitis with profuse expectoration, leucorrhcea, and similar exhausting discharges, may be much improved by the phosphates, and with the general improvement of the bodily state there usually takes place an arrest of the local morbid process. The explanation of the therapeutical action of the phosphates in the diseases just mentioned is equally true of their use in phthisis. The utility of the hypophosphites in this disease is not any greater, for it is probably true that these preparations undergo oxidation in the stomach and pass to phosphates. The compound sirup of the hypophosphites is an agreeable preparation and is readily taken, and certainly proves serviceable in the more chronic forms of the disease. The lacto-phos- phate, the phosphates, and the hypophosphites, are undoubtedly useful in chronic phthisis, fibroid lung, chronic tuberculosis, emphysema, and dilated bronchi, but no advantage can be expected from them in acute tuberculosis and caseous pneumonia. The utility of these preparations in these groups of maladies depends on their power to promote con- structive metamorphosis. If they improve the appetite, promote diges- tion, and increase the body- weight, they do good ; if they disagree with the stomach, they do harm (Bennett). Not unfrequently the sirup of the hypophosphites gives rise to distressing tormina. This may be obviated by combining with it dilute phosphoric acid — a combination very effective, therapeutically : $ Syrp. hypophos. comp., 1 iijss ; acid, phosphor, dil., § ss. M. S. : A teaspoonf ul three times a day. Such a combination may be advantageously given with cod-liver oil, after meals, in chronic phthisis. The addition of arsenic contributes very materially to the therapeutical effects of the lacto-phosphate ; for example : I£ Syrp. calcii lacto-phos., 3 iv ; liq. potassii arsen., 3 j. M. S. : A dessert- spoonful ter die. Late favorable reports regarding the curative effects of phosphorus and its compounds in pernicious anaemia have not been confirmed by the most recent experience. Percy, who has distinguished himself by researches on phosphorus, prepares hypophosphorous acid by passing through a solution of phos- phorus in oil, perfectly pure and dry oxygen. He maintains that hy- pophosphorous acid is the only preparation of phosphorus which should be employed in medicine. Further experience with the phosphate of soda justifies the author in the expression of his belief that it has the power to retard the growth of the changes known as sclerosis of the liver, and possibly, under favorable circumstances, to arrest them and to restore a com- paratively normal functional state. When, in obese subjects, a succes- sion of boils portends the development of diabetes, this remedy is highly useful. It has seemed very beneficial in the hepatic form of diabetes. No remedy is more effective in removing that condition of the system which produces furuncles, or boils. IRON. 123 IRON AND ITS PREPARATIONS. Ferrum. — Fer, Fr. ; Eisen, Ger.

It is odorless, without the styptic taste of the ferruginous preparations, does not blacken the tongue and teeth, is free from irritant action, and does not constipate. It is precipitated by sulphuric acid, by acids, and by various salts, but neither by alcohol nor sugar. It is doubtful whether it be a good form in which to administer iron. Dose, tti, v — 3 i. If 126 RESTORATIVE AGENTS. any given preparation has a styptic taste, and acts on the tongue and teeth, it is not genuine. Reduced iron is one of the most useful ferruginous preparations for internal administration, comparatively tasteless, and therefore easy of administration, and readily soluble in the juices of the stomach. The objection to its use is the occurrence of eructations, sulphureted or phosphureted, owing to the oxidation of the iron, the evolution of hydrogen, and the combination of the nascent hydrogen with sulphur or phosphorus. The so-called subcarbonate of iron is really little more than the red oxide. In the official pilulae ferri carbonatis, the oxidation of the iron and the loss of carbonic acid are prevented by the sugar. This prepa- ration is very soluble in the stomach-juice, and is readily assimilated. The troches of carbonate of iron are convenient for administration to children, who take them readily. The hydrated oxide of iron is solely used as the antidote to arsenic in solution. For remarks on its admin- istration I have to refer the reader to the article on Arsenic. Corre- sponding to these carbonates are the pilulse ferri compositse, which contain iron in the form of the carbonate, sulphate of soda, and myrrh. The mistura ferri composita is also a solution of the carbonate, con- tains myrrh and sulphate of potash, with a sufficient quantity of the latter to form an emulsion w^hich suspends the iron. Of the phosphates the better preparation is the pyrophosphate, which is readily soluble, unirritating, and easily assimilable. The sul- phate is an active astringent, and is an efficient remedy. When pre- scribed in pillular form the dried sulphate should be used, as the sul- phate in efflorescing destroys the cohesion of the mass. Of the several solutions intended for topical use, the liquor ferri subsulphatis, or Monsel's solution, is the best, as it is powerfully styptic without being corrosive. The tincture of the chloride of iron is most agreeably taken in the form of Creuse's tasteless preparation, which appears to be an efficient chalybeate without possessing the causticity of the pharma- ceutical preparation. In the sirup of the iodide of iron and the sirup of the iodides of iron and manganese, sugar is used to prevent oxida- tion of the iron and the setting free of the iodine. In the iodide-of- iron pill the same result is obtained by sugar or gelatin coating. Less irritating to the stomach, but probably less efficient as chalyb- eates, are the combinations of iron with vegetable acids. These may be administered dissolved in Rhine, Catawba, or sherry wine. An elegant mode of prescribing them is in effervescence — the citrates or tartrates dissolved in a solution of citric or tartaric acid, and poured into a solution of sodium or potassium bicarbonate — to be drunk in effervescence. Antagonists and Incompatibles. — The carbonates are incompati- ble with acids and acidulous salts and vegetable astringents ; the IRON. 127 citrates and tartrates with mineral acids, alkalies and their carbonates, tannic acid ; the iodides with acids, acidulous salts, alkalies and their carbonates, lime-water, vegetable astringents ; the tincture of the chloride, with alkalies and their carbonates, lime-water, carbonate of lime, magnesia and its carbonate, and astringent vegetables turn it black. Synergists. — All agents promoting constructive metamorphosis are synergistic to iron, especially animal aliment, the simple, aromatic, and astringent bitters, cinchona, manganese, bismuth, etc. Physiological Actions. — Although metallic iron is inert, yet in the stomach it enters into combination dissolved in the acids, and then acquires molecular activity. As a result of its oxidation in the stomach, hydrogen is liberated, which in its nascent state combines with sulphur, forming sulphureted hydrogen. In part, iron is ab- sorbed by the stomach, probably as an albuminate ; in part, in the intestinal canal. The stools under a course of iron become brownish and even black, a result which indicates that a part of the metal taken fails to be absorbed ; but, since it has been shown that, whether taken by the stomach or injected into the blood, elimination takes place by the intestinal canal, it remains uncertain how much is excreted or is merely discharged unaltered in the faeces. Iron is not a substance foreign to the organism. Chemical analysis has demonstrated its constant presence in the blood, in the gastric juice, chyle, lymph, bile, in the pigment of the eye, and in traces in the milk and urine. According to Gorup-Basanez (analysis of C. Schmidt), the blood of man contains one part of iron to 230 of red globules, and that of beef one part of iron to 194 of red globules. Iron exists in com- bination in haematin ; according to some in the state of oxide, accord- ing to others as metallic iron. That it performs a very important office is shown in the rapid construction of red blood-globules when iron is administered in anaemia. Without it haematin is not formed, and the red globules diminish in number. By its medicinal use we furnish to the blood a material which it needs. In health a mixed diet contains sufficient iron for all the purposes of the economy. The blood being improved in quality by the administration of iron, the tissues- are better nourished, and all the functions are performed with more vigor. The physiological action of iron is not limited merely to the con- struction of red blood. When there is no intolerance to its presence in the stomach, it promotes the appetite and invigorates the digestion. By increasing the disposition for food and the ability to dispose of it, iron acts as a stomachic tonic. Hence, when given in the healthy state, or when administered for too long a period in disease, the gas- tric glands become exhausted by over-stimulation, and then it is said the iron disagrees. Being a restorative, its use is contrainclicated in a condition of plethora, especially when there exists a tendency to haem- 128 RESTORATIVE AGENTS. orrhage, or when there is reason to suspect an atheromatous state of the cerebral vessels. In large doses the soluble preparations of iron give rise to nausea and vomiting. Some of them possess more or less toxic activity ; the per-salts are more active than the proto-salts. The iodide and chloride, the nitrate and sulphate, are the most active, death having ensued from the tincture of the chloride in one case (Christison), and alarm- ing symptoms having occurred in others (Taylor). Certain of the salts of iron, the sulphates, the nitrates, the chlo- rides, possess a high degree of astringency. Hence they produce con- stipation when taken internally. Brought into contact with blood, they coagulate it, forming a tough, brownish magma ; and, as the al- buminous elements of the tissues are also solidified, they are powerful haemostatics. Iron is eliminated by several channels. Its passage down the in- testinal canal and exit by this route have already been alluded to. As the experiments of Lussana have shown, a large part of the iron which enters the portal circulation is eliminated by the liver in the bile. On the other hand, the chief part of the iron which is made to enter the systemic circulation is eliminated by the kidneys. Much of that which is absorbed from the intestinal canal enters the capillary system of the liver, diffuses through into the bile, and but a small part finally enters the systemic circulation. The acid and astringent preparations of iron act on the teeth with considerable energy, as the experiments of Dr. Smith (of Edinburgh) prove. The tincture of the chloride and the sulphate are more corrosive than the wine, and of course are more injurious than the compounds of iron with the vegetable acids. Therapy. — Iron-spray — a weak solution of the liquor ferri subsul- phatis ( 3 j — § viij) — is very serviceable as an astringent in obstinate cases of epistaxis. The nozzle of the delivery-tube of the spray-douche should be inserted just within the anterior nares, and the spray be driven with considerable force. The same application is beneficial in chronic coryza, but the objection to its use is the danger of coloring the teeth. In pulmonary haemorrhage, the same application made to enter the throat with the inspired air will often arrest the flow of blood ; and this, notwithstanding so little iron can pass the chink of the glottis. The subsulphate and pernitrate solutions are the most efficient remedies for arresting hcematemesis. They should be given in small doses — one or two drops, well diluted with ice-water, and frequently. In the absence of these, the tincture of the chloride may be used in the same way. In intestinal hemorrhage the astringent preparations of iron are much less beneficial, if, indeed, they serve any useful purpose — for they are converted into inert sulphides as they descend the canal. IRON. 129 The author has seen the intestinal haemorrhage of typhoid fever much increased by the rectal injection of a solution of Monsel's salt. The bleeding from hemorrhoids may be much diminished and even arrested by washing the tumors, when they protrude, with the solution of the subsulphate. After the application of the iron, the tumors should be well oiled before returning them into the rectum. The solution of the pernitrate of iron has been very efficacious as an astringent in chronic diarrhcea and dysentery, in that known as the army diarrhoea. These diseases, as they occur in civil practice, may sometimes be arrested by this agent, but not usually, in the author's experience. A solution of the tincture of iron is one of the numerous remedies used to destroy the ascarides vermiculares — the thread- worms which infest the rectum. As the development of these parasites is favored by the anaemic state, it is good practice to conjoin with any local treatment the internal use of iron, notably the sirup of the iodide. Iron is frequently given with advantage to promote appetite and digestion merely. Indeed, it is the opinion of some eminent authori- ties that the chief use of iron as a remedy, even in anaemia, is to pro- mote the digestive function. For the purpose of increasing appetite and energizing digestion, the sulphate is the best chalybeate, unless, indeed, the mucous membrane prove intolerant. When digestion is feeble, and the intestinal movements sluggish, it is often advantageous to combine aloes with iron, as in the official aloes-and-iron pill, or with sulphate of magnesia, as in the mistura ferri laxans, the formula for which has been given. The condition most usually requiring iron is anosmia, a deficiency not only of the haematin but of the red corpuscles. Iron is given in this state with the view of supplying to the organism a material in which it is deficient, and in this way promoting the construction of the red globules. As, however, food, especially beef, is rich in iron, and as but a small amount of that administered is really assimilated, there is much reason for holding that at least an important function of iron in anaemia consists in its power to promote appetite and digestion. Practical physicians are familiar with the fact that iron improves but little, if at all, the condition of the anaemic, when it does not increase the desire for food and the ability to digest it. In anaemia, iron is given with two objects : to furnish a needed material to the blood ; to increase the energy of the primary assimilation. To accomplish the first object, small doses — one or two grains — of reduced iron or of the carbonates, or some one of the combinations with vegetable acids, are most suitable. The second object is best attained by the more active astringent preparations, especially the sulphate and the chloride. Large doses of these are frequently well borne. When they disagree, other salts may be tried, but preference should be given to the most astrin- gent preparation which the patient's stomach will tolerate. 130 RESTORATIVE AGENTS. In chlorosis, the good effects of iron are not so conspicuous as in anaemia, although they are allied states. During a course of iron in chlorosis, purgatives are now and then necessary. Better results are obtained from a combination of iron and arsenic, and iron and strychnine, than from iron alone. The arseniate of iron is an excellent remedy in chlorosis, but it must be given in larger doses than the posological tables authorize, for it is by no means so actively toxic as is commonly supposed. A good formula is the following : 3 Ferri arseniat., gr. ij ; ext. cinchonae, gr. xij. M. Ft. pil. no. xij. Sig. : One three times a day after meals. In anaemia and chlorosis, the iron should be taken after meals to be mixed with the food. The preparations of iron should not be continued too long ; occasional intermissions in their use are necessary, otherwise the digestive organs become deranged, and the good effects are lost. Occasional purgation is useful, and acts in a way to favor the absorp- tion and assimilation of the iron. Air and exercise should always, if practicable, be prescribed in a ferruginous course, for the assimilation of iron is directly favored by these hygienic influences. The anaemia of chronic malarial poisoning is especially improved by iron. If enlargement of the spleen and engorgement of the portal circulation co-exist, the use of the compound jalap-powder should pre- cede the iron ; or the latter may be combined advantageously with resin of podophyllin, as follows : ^ Quininae, 3 j ; resinae podophylli, gr. iv ; ferri sulphatis exsic, 3j.

Although the preparations of iron are of little service in leucocy- thaimia, they are certainly in a high degree useful in pseudo-leucocy- thmmia, or cachexia of the spleen. In the latter disease the relative number of blood-corpuscles may be greatly reduced, but they can be increased in number and raised to the normal by the use of those materials needed by the blood-making organs, especially by the use of iron. In syphilitic cachexia, the preparations of the iodide of iron possess a high degree of utility. In sloughing phagedena, or simple chancroid, the iodide is frequently prescribed when these accidents occur in debili- tated constitutions. Some authorities prefer the tartrate of iron under these circumstances, but the iodide acts with more promptness and IRON. 131 vigor. In the treatment of constitutional syphilis, the ferruginous prep- arations are only useful in so far as they may be applied to promote constructive metamorphosis. More commonly than is supposed by the advocates of special plans of treatment, tonic remedies, especially cha- lybeates, exercise a most favorable influence over the course and dura- tion of syphilis. $ Iodoformi, 3 j ; hydrargyri chloridi corrosiv., gr. j ; ferri redacti, 3j.

Iron is one of the remedies most useful in the treatment of acute rheumatism. As was originally suggested by Reynolds, the tincture of the chloride is most serviceable. It is more especially adapted to the treatment of pale, delicate, and cachectic subjects, and is much less beneficial, if not positively harmful, in the plethoric and overfed. Given in suitable cases, the tincture of iron, in doses of Tq, xx — xxx every four hours, diminishes the pain, fever, and sweats, lessens the chances of cardiac mischief, and hastens convalescence. By retarding waste and favoring excretion of uric acid through the kidneys, the duration of the disease is shortened and a tedious convalescence is pre- vented. We owe to Dr. Anstie the important suggestion that tinc- ture of chloride of iron may be used successfully as a prophylactic against acute rheumatism. Here, again, the author must state, as a result of his personal observation, that such prophylactic treatment is very useful in weak and cachectic subjects and not applicable to the robust and full-blooded. The tincture of iron should be administered without delay in such weak subjects with a rheumatic history, when they complain of lassitude, muscular pains, sore joints, furred tongue, although they are yet free from fever and joint-swellings. The treatment of erysipelas by large doses (in, x — 3 j every four hours) of tincture of chloride of iron is now very generally adopted. It is questionable whether this practice is directly beneficial. Its utility depends chiefly on the support which it affords to the organism while laboring under a debilitating disease, and, as an abundant supply of aliment is prescribed with the iron, it is impossible to estimate in any given case how far the result may be attributable to the remedy. Influenced by the same considerations, the tincture of iron is fre- quently prescribed in diphtheria, alone or in combination with chlorate of potassa. Although it possesses no special utility in this disease, it may serve as one of the means for maintaining the forces of the body, and in this way indirectly contribute to a favorable result. There is no advantage in applying the tincture of iron to the fauces in diph- theria ; it is not a solvent of the false membrane, and can not prevent the spread of the exudation ; it is, however, now freely used, and it is said with good results. In the treatment of scrofula, strumous enlargement of the cervical, 132 RESTORATIVE AGENTS. inguinal, and mesenteric glands, and in rickets, the preparations of iron occupy a most important place. In these affections the sirup of the iodide of iron is generally preferred, and excellent results are obtained from a combination of phosphate of iron and phosphate of lime, espe- cially in rickets. In these cases, also, the sirup of the iodides of iron and manganese is indicated. Iron is one of the remedies most fre- quently prescribed in chronic tuberculosis, but it has no special influ- ence over the deposition of tubercle. It helps to a better state of the blood-making process, and, by promoting the constructive metamor- phosis, hinders the progress of the malady. As neuralgia so often depends on anaemia, it happens that iron is one of the most frequently prescribed remedies for this disease. Anstie prefers large doses (th, xxx — xl ter die) of the tincture of the chloride, and twenty-grain doses of the saccharated carbonate twice or three times a day. In disorders of the mind, either dependent on or increased by an anaemic state, iron is often useful. In chronic mania and melancholia, when debility is present, iron is employed as a restorative agent. The ferruginous preparations are especially useful in the anaemic forms of puerperal mania, and in the insanity of lactation. Bucknill and Tuke prefer the tincture of the chloride in these affections. Whenever epilepsy occurs in weak and anaemic subjects, iron is indi- cated. Cases of this disease, essential in character and dependent on cerebral anaemia, are sometimes cured by iron alone. The author has seen excellent results from a combination of bromide of iron and bromide of potassium in such cases : fy Potassii. bromidi, § j ; ferri bromidi, gr. iv ; aquae, f ij ; syrup, simplicis, § vj. M. Sig. : A table- spoonful bis die. Large doses of subcarbonate of iron have long been used with ad- vantage in chorea. When the subject of this disease is distinctly anaemic, iron, in some of its forms, is unquestionably serviceable, and its utility is often increased by combination with purgatives. When anaemia is not present, arsenic is preferable to iron. Chorea arising from moral causes (anger, fright, etc.), and from pregnancy, is not benefited by iron. This remedy is especially adapted to the chorea of anaemic girls about the age of puberty. The preparations of iron are of course inadmissible in acute affec- tions of the respiratory organs, but, in certain of the chronic forms and stages of these diseases, some of the chalybeates are very useful. In chronic bronchitis, with free expectoration, the mistura ferri com- posita has long been used with advantage. At the present time the phosphate of iron, quinine, and strychnine, is generally preferred in chronic bronchitis, in the chronic forms of phthisis, in emphysema, and in humid asthma. Iron is contraindicated when pulmonary haem- orrhage exists or is threatened. A combination of tincture of digitalis IRON. 133 and tincture of chloride of iron abates the temperature and diminishes the sweats of hectic fever. 3 Tinct. digitalis, 3 iij ; tinct. f erri chlo- ridi, 3 v. M. Sig. : Fifteen drops three or four times a day. In fatty degeneration of the heart, the preparations of iron render important service, by improving the nutrition of the organ. The pal- pitations, the murmur, and precordial anxiety which accompany cases of anaemia and chlorosis, are relieved by chalybeate medicines. In dilatation of the cavities of the heart, especially the right, accompanied by cough, difficult breathing, and general dropsy, greater relief is some- times experienced from the preparations of iron than by the so-called cardiac sedatives and diuretics. In these cases, as also in mitral regurgi- tation, the distress of the patient increases with increasing thinness of the blood, and is diminished by those remedies, such as iron, which improve the quality of the blood. A combination of iron, digitalis, and squill, is sometimes extremely serviceable in these cases — for example : 1} Ferri redacti, quininae sulphat., pulv. digitalis (English), aa 3 j ; pulv. scillae, gr. x. M. Ft. pil. no. xx. Sig. : One pill three or four times a day. Iron may be used with advantage to assist in the process of compensation in valvular lesions, when the condition is one of anaemia. Iron is contraindicated in all cases of cardiac disease occurring in those who are full-blooded. In the passive forms of hemorrhage — in purpura, the hemorrhagic diathesis, epistaxis, gastric, intestinal, and renal hemorrhage, when they are due to anaemia or favored by it — iron is unquestionably use- ful, and the preparation most generally applicable is the tincture of the chloride. Derangements of the menstrual function, when associated with anaemia, more especially when produced by anaemia, are often removed by the use of chalybeate medicines. Amenorrhea is, more frequently than to any other cause, due to anaemia of the ovaries, consecutive to chlorosis or general anaemia, and dysmenorrhea may depend, in one of its forms at least, upon the same condition of the blood. Menorrhagia may also be one of the results of an impoverished state of the blood. Iron is the most appropriate medicament in these disorders. It is the judgment of Graily Hewitt and Barnes that " small doses of iron are generally the best " in amenorrhea. Barnes prefers the solution of the acetate, and speaks favorably of the citrate of iron and ammonia, given in an effervescent state, and of the combination of iron and strychnine. The use of ferruginous preparations in menstrual disorders should be determined by the results of a careful differentiation of the causes. The absence of the uterus and ovaries, occlusion of the cervix, and various other conditions besides anaemia, should be eliminated, and the use of iron restricted to those cases in which an impoverished state of the blood is either the only factor or an influential one. The iDJection of the various styptic solutions of iron into the 134 RESTORATIVE AGENTS. uterine cavity, to arrest post-partum haemorrhage, is now common practice. Notwithstanding the alleged innocuousness of this treat- ment, it is probable, as Snow Beck has shown, that fatal results have ensued from the incautious use of these injections. The official solu- tions of the perchloride and subsulphate have been thrown into the uterine cavity, with the effect to cause uterine thrombosis, followed by systemic infection. These solutions are much too strong ; one part of Monsel's solution to three of water is sufficiently styptic, and is probably perfectly safe. The uterine cavity should be cleared of clots, and the nozzle of the syringe carried well up to the fundus, when the injection should be slowly delivered. The reader need hardly be re- minded that this expedient is only proper after the usual means for securing uterine contractions have failed. The same plan of styptic injections has been used to arrest the haemorrhage from abortion, but caution is necessary in these cases, for it is essential to safety that there be an open and patulous condition of the os, to permit escape of coagula. Similarly these injections are used to restrain bleeding in cases of uterine fibroids, uterine cancer, and in the uterine haemorrhage dependent on spongy granulation of the mucous membrane. In every case of such use of styptic iron injections, it is essential, first, that air be not pumped into the uterine cavity, and second, that sufficient dila- tation of the cervical canal exist to permit ready exit to the surplus fluid and coagula. In albuminuria, connected with chronic changes of the kidney, iron is often very serviceable to improve the digestion, and to correct the anaemia, which is such an obvious feature of these maladies. The tincture of the chloride and the tincture of the acetate — especially the latter — are preferred, partly on account of their value as haematinic remedies, and partly because of their supposed diuretic action. When spermatorrhoea is dependent upon an impoverished condition of the blood, with relaxation of the vesiculae seminales, the tincture of iron is useful, but it is rarely of itself sufficient to effect a cure. The chalyb- eates are only harmful in those cases of nocturnal seminal losses which in the robust are merely significant of plethora. In gleet occurring in anaemic subjects, and in the prostorrhoea and catarrh of the urethra which arise from relaxation, the preparations of iron are useful adjuncts to other measures.

The sirup of iodide of iron is one of the most successful remedies in the nocturnal incontinence of urine in children. The precise indi- cations for its use are not evident.

Local Uses. — The styptic preparations of iron are frequently used to restrain haemorrhage. Leech-bites that bleed too profusely, haemor- rhage after extraction of teeth or in minor surgical operations, oozing from a large wounded surface, may often be checked by the use of Monsel's solution. As a topical application in gonorrhoea after the acute symptoms have subsided, in mucous cervicitis, in leucorrhoea, the styptic prepa- rations of iron are certainly useful, but a strong objection to their use arises from the staining of the clothing. Monsel's solution is an effective application to fissured nipples : 3 Liquor f erri subsulphatis, 3 ij ; glycerini, 3 vj. M. Sig. : Apply with a camel's-hair brush to affected parts.

Syrupus Mangani Iodidi. — A sirup which corresponds in strength to the official sirup of the iodide of iron, and may be given in corre- sponding doses. Besides the above, a carbonate, phosphate, tartrate, malate, and lac- tate have been proposed for use, but hitherto they have not attracted attention and are rarely employed. The official and unofficial prepa- rations named above are all that, according to the present state of pro- fessional experience on the subject, will ever be required. It will be most convenient, however, to include with the manganic preparations the following : Potassii Permanganas. — Permanganate of potassa. In needle- shaped crystals of a deep purple color. It is soluble in sixteen parts of cold water, and the solution has a deep purple to a rose-color, ac- cording to the state of dilution of the salt. Dose, gr. ss — gr. ij. In prescribing the permanganate, distilled water free from organic matter should be directed. Physiological Actions. — The sulphate has an extremely disagree- able styptic and metallic taste ; the black oxide less so, and the saccha- rated carbonate is free from any taste except that of the sugar. The preparations of manganese are somewhat irritant to the gastrointesti- nal mucous membrane, and the sulphate is emeto-cathartic in full doses. There seems to be no doubt that the sulphate has a decided cholagogue effect, for very large discharge of bile is a result of its cathartic action. In small doses the manganic salts promote the appetite and digestive function. They probably enter the blood as albuminates. The inti- mate association of manganese with iron throughout the economy of Nature is exemplified in the human body. They are found together in the blood, hair, bile, biliary concretions, and renal calculi. The pro- portion of manganese to iron in the red blood-corpuscles is as one to twenty. As an essential constituent of the blood, it undoubtedly has to do with the constructive metamorphosis of the body. Used in large doses and for a considerable period of time it produces effects analogous to those of zinc — progressive wasting and feebleness, a staggering gait MANGANTTM. 137 and paralysis (paraplegia). In toxic doses, according to the researches of Laschkewitsch, it causes in animals death by convulsions. In smaller doses it diminishes the pulse-rate, lowers the action of the heart, and lessens the blood-pressure. Like phosphorus, manganese induces acute fatty degeneration of the liver. When it is injected into the veins of animals, it causes tetanic cramp, dilatation of the pupil, exophthalmus, and death ; and after death the heart-muscle does not respond to elec- trical stimulation (Laschkewitsch). Antagonists. — The preparations of manganese are not incompat- ible with the vegetable astringents. The salts of lead, silver, and mercury, and the caustic alkalies, are chemically incompatible with manganese. Syneegists. — Iron is synergistic as regards hsematinic effects, and the salts of copper, silver, and zinc, as regards the effects on the nervous system. Theeapy. — Although manganese has not of itself been very useful in the treatment of anaemia and chlorosis, yet there is no doubt that its combination with iron much increases the efficacy of the latter. Some of the preparations named at the head of this article, especially the saccharated carbonate of manganese and iron, may be usefully pre- scribed in these diseases. Cachectic states arising from syphilis, can- cer, struma, gout, prolonged suppuration, chronic malarial infection, etc., are successfully treated by the sirup of the iodide of iron and manganese. Gastrodynia and pyrosis, according to Dr. Leared, are relieved by ten to fifteen grain doses of the black oxide — not the commercial article, but the oxide purified by washing with hydrochloric acid. In these disorders the effects of manganese are similar to those of bismuth (nitrate and carbonate), of zinc, and silver (oxide). Small doses of manganese (sulphate) may be usefully combined with iron and quinine when prescribed to promote constructive metamorphosis. 3 Quininse sulph., ferri sulph. exsic, mangani sulph. exsic, aa 3 j.

In the disordered digestion of gouty sub- jects, and to restore the activity of the assimilative functions after attacks of gout, manganese is most serviceable.

M. Oint- ment for porrigo. Actions and Uses of the Permanganate of Potassa. — This salt is a very powerful oxidizing agent, and yields up its oxygen readily in the form of ozone. Its use as an internal and external remedy is based on this chemical fact. That it parts with its oxygen so readily is held by some to demonstrate its entire inutility when administered by the stomach. Although it must instantly be decomposed on reaching the stomach, there are satisfactory reasons for believing that it exerts a favorable influence on certain diseases in which, theoretically consid- ered, it may be indicated. The author has seen marked advantage from its use in the dyspepsia and flatulence so constantly attendant on obesity. It has also ajmeared to be very serviceable as a remedy for an abnormal and excessive deposition of fat. In the so-called uric-acid diathesis it favors the conversion of uric acid into urea, and thus pre- vents the formation of uric-acid calculi. Pain in the lumbar region, frequent micturition, acid urine, much brick-dust sediment, and intes- tinal indigestion, are associated symptoms relieved by the perman- ganate. Under the same conditions, it is probable acute rheumatism is developed, and to the action of the permanganate as an oxidizing agent is attributable the benefit which is sometimes obtained from its use in this disease. In scarlatina and diphtheria the permanganate is used with undoubted benefit, applied to the throat and taken by the stomach. In erysipelas, puerperal fever, septicaemia, it has been given with advantage. Lately it has been used with success as a remedy for the bites of venomous snakes and other animal poisons, applied locally and given internally. Drs. Ringer and Murrell have found it an effective remedy in the treatment of amenorrhoea, one or two grains being given in pill form three times a day. It is difficult to prepare the pills, and they are said to be liable to spontaneous com- bustion. For internal use the permanganate is best administered in pure distilled water, and the bottle containing the solution should be glass-stoppered. The dose for internal use is gr. £ — gr. ij ter die. Among the important uses of permanganate of potassa are its ex- ternal applications as a disinfectant. It is a deodorizer as well as a disinfectant. It is very frequently used ( 3 j — Oj) to correct the fetor of cancer, ulcers, caries, abscesses, etc. It is used as an injection, or in the form of spray, to destroy the odor of the discharges and to alter the morbid action, in cases of ozcena, otorrhoea, etc. It is an elegant toilet preparation (gr. j — 1 j) for destroying the odor of a foul breath, the smell of the axilla, and the fetor of the sweat of the feet. Its action is not lasting, and the effects must be maintained by frequent appli- cations. The permanganate of potassa iu solution (gr. ij — 1 j) is one of the CHALYBEATE SPRINGS. 139 numerous remedies prescribed in gonorrhoea and leucorrhoea, but it has no special advantages in these maladies. When the permanganate is deoxidized it loses its rich purple color, becomes a dull red, and is reduced to the state of binoxide of manganese. Authorities referred to : Hermann, Dr. L.

These springs contain carbonates of potassa, soda, magnesia, car- bonic-acid gas, oxide of iron, etc. Rawley Springs, Rockingham County, Virginia. Carbonate of iron (0*203 grain) is the most important ingredient in these waters. They contain, also, carbonates of manganese, magnesia, lime, and lithia, and sulphates, etc. Sweet Chalybeate Springs, Alleghany County, Virginia. The name of this water is derived from its sweetish taste. It is highly charged with carbonic-acid gas, and contains sesquioxide of iron, with sulphate of lime (4*110 grains), sulphates of magnesia and soda, and chlorides of lime, sodium, magnesium, etc. Rockbridge Alum Springs, Rockbridge County, Virginia. Bath Alum, Bath County, Virginia. These waters are remarkable for containing free sulphuric acid. They contain also sulphates of magnesia and lime, protoxide of iron, and carbonic- acid gas. The Bath Alum waters contain twice as much iron as the Rockbridge Alum. Bedford Alum Springs, Bedford County, Virginia. Similar in composition to the above, but contain a larger proportion of iron, and of the salts of potassa, magnesia, and lime. Bedford Springs, Bedford County, Pennsylvania. This water contains carbonate of iron (0*625 grain) associated with a large proportion of sulphate of magnesia (10 grains), and is, there- fore, a laxative chalybeate. 2. ElJEOPEAN. Bascombe, Bournemouth, Hampshire, England. Chalybeate springs containing carbonic acid in combination. 140 RESTORATIVE AGENTS. Dorton, Buckinghamshire, England. Contains sulphate of iron and is charged with carbonic acid. Re- quires dilution for drinking. Hastings, Sussex, England. Contains sulphates of iron, magnesia, lime, and soda. Sandrock, Isle of Wight. Is a strong aluminous chalybeate — 41^ grains of sulphate of iron, and 31^ grains of sulphate of alumina in twenty ounces — and therefore requires dilution for drinking. Tunbridge, Kent, England. Altitude, 289' ; temperature, 50° Fahr. This water contains one eighth of a grain of iron with carbonic acid, in twenty ounces. Spa, Belgium. Altitude, 1,030'. Season, August and September. Temperature of water, 52° Fahr. These waters contain carbonates of iron, manganese, soda, lime, and magnesia, etc., and are highly charged with carbonic acid. Pyrmoilt, Waldeck. Altitude, 404' ; mean annual temperature, 48-5° Fahr. The quantity of carbonic-acid gas is unusually great in these waters. They contain sulphates of lime, soda, magnesia, and carbonates of iron, soda, magnesia, and lime. Alexisbad, near Harzgerode, Germany. Alexisbrunnen. Same. Both contain iron and manganese in large quantity, and also car- bonic-acid gas. The first named, being highly impregnated with chloride and sulphate of iron, is used for bathing, and the other for drinking. Schwalbach, Nassau. Altitude, 909'. Season, June to September. Temperature, 64° Fahr. According to the analysis of Fresenius, this valuable water contains bicarbonates of iron, manganese, soda, magnesia, and lime, sulphates of soda and potash, and chloride of sodium. It is very highly charged with carbonic acid. St. Muritz, Upper Engadin, Switzerland. Altitude, 5,464'. Mean temperature of summer months, 51° Fahr. These springs contain from ten to fourteen grains of solids in a pint, consisting of carbonates of lime, magnesia, manganese, iron, and soda, etc., and as much as 39'5 cubic inches of carbonic acid. Therapy of Chalybeate Waters. — The uses of these waters are the same as the purely medicinal preparations of iron. They are in- dicated in chlorosis and anaemia, to supply to the blood the material in which it is deficient. For this purpose the milder waters, contain- ing carbonate of iron and abundant carbonic acid, are most suitable ; for example, in this country, Rawley Springs, Sweet Chalybeate, Bed- ford (Pennsylvania) ; in England, Bascombe and Tunbridge ; on the Continent, Pyrmont, Spa, Schwalbach, St. Moritz. When passive hmm- BISMUTH. 141 orrhages — the hemorrhagic diathesis — require ferruginous waters, the alum and iron waters are more effective. Amenorrhea, hysteria, and other pelvic disorders, when dependent on anaemia, the paludal cachexia, leucocythemic-exophthalmic goitre, are either cured or de- cidedly ameliorated by chalybeate waters. The purgative iron waters are useful in engorgement of the liver, haemorrhoids, and dyspepsia of ancemic subjects, in albuminuria and dropsy ; the alum springs in chronic diarrhoea and strumous diseases. Neuralgia, chorea, cerebral anaemia, and other nervous disorders due to an impoverished condition of the blood, are much improved by the use of the milder chalybeate waters. In making selection of a chalybeate water, the psychical influences of mountain scenery, or other pleasant surroundings, should not be dis- regarded. For the anaemic pulmonary invalid, elevation of the spring and the absence of humidity are important considerations to determine a selection. Hence, the present popularity of St. Moritz. In this coun- try a great variety is afforded — mountain scenery like Bedford, Penn- sylvania, and the Virginia springs, or rolling upland like Bailey's and Sharon. As respects composition, the ferruginous springs of the United States are equal to any in the world. For authorities referred to, see articles on Alkaline and Saline Springs. None of the remedies heretofore considered, contained in the group of agents promoting constructive metamorphosis, are foreign to the organism. They are all necessary to and directly promote the forma- tion of the blood and tissues. In the same group, however, are remedies which, while they are tonic and reconstituent, do not enter into the composition of the body. They promote, in an indirect way, the constructive metamor- phosis. Among these are bismuth, arsenic, the simple bitters, cinchona and its alkaloids. These agents having performed their office, are, after a variable period, eliminated from the organism. Their thera- peutical effects can not be entirely comprehended in the process of constructive metamorphosis, and in the ultimate results of their physi- ological actions the destructive metamorphosis may be included.

Besides these official preparations, various compounds of bismuth are prescribed. None of these present any advantages over the official forms, and most of them are objectionable from various considerations. The solutions of bismuth do not produce the effects of the insoluble subcarbonate and subnitrate, and the various trade preparations con- taining bismuth and pepsin, bismuth and strychnine, bismuth and cali- saya, etc., are, to the last degree, unscientific and unreliable. Physiological Actions. — The insoluble preparations have a very slightly metallic taste. They coat the tongue black by the formation of a sulphide. Given in suitable cases, they promote the appetite and increase the digestive power, and a gain in body-weight is one result of their administration. They are somewhat astringent, and retard the intestinal movements. As they are nearly insoluble, they pass dcwn the intestinal tract and are converted into sulphides ; hence the faeces under their use become a dark slate color. They are not entirely in- soluble, for bismuth can be detected in the blood, urine, and other secretions, after a course of these medicines. Sufficient is absorbed under some circumstances, it is said, especially after prolonged admin- istration, to cause toxic symptoms ; but such a result must be due to accidental combinations, or to the presence of arsenic, which is a very constant impurity in the ordinary commercial preparations of subni- trate and subcarbonate of bismuth. Trousseaux and Pidoux remark, with regard to its presumed toxic effect, as follows : " When the sub- nitrate of bismuth has been prepared from the perfectly pure metal, precipitated and well washed, it may be given in single doses from one to four grammes (fifteen grains to a drachm) without producing the least malaise" According to the same authority, Dr. Monneret has often given as much as ten to sixty grammes a day, without any recog- nized ill effects. It may, therefore, be concluded that the action of bismuth is chiefly local. Therapy. — In the aphthm of children, nursing sore-mouth, the milder cases of mercurial salivation, and in those painful ulcers of the mucous membrane of the mouth due to disorders of digestion, bis- muth applied freely to the affected parts is often very serviceable, by diminishing the pain and promoting the healing process. Bismuth allays the irritability of the mucous membrane in cases of acute indi- gestion, if given after the contents of the stomach are fully evacuated. It is especially indicated when there is not only painful digestion, but BISMUTH. 143 a tendency to diarrhoea, the inclination for stool coming on soon after the food has been taken. It is given with great advantage in subacute and chronic gastritis, and in gastralgia arising from a state of irrita- tion of the gastric mucous membrane. It is contraindicated, and is not beneficial, in the gastralgia produced by habitual constipation and in the gastralgia of chlorosis and hypochondria. The pain and vomit- ing attendant on gastric ulcer and scirrhus of the stomach are relieved by bismuth, and in the case of the former disease this remedy con- tributes to the cure. In these painful affections, the good effects of the bismuth are enhanced by combination with morphine. P> Bismuthi subnitrat., 3 ij ; morphines sulphat., gr. j. M. Ft. pulv. no. vj.

Although arsenic as an impurity is so objectionable that special pains are taken in the pharmaceutical process to separate it in the preparation of subnitrate, yet the author has witnessed excellent re- sults from a combination of arsenic and bismuth in the more chronic stomach-disorders for which the latter is prescribed. When bismuth is not well borne by the stomach, it may be com- bined with aromatic powder, or, when alkalies are indicated, it may be given with chalk or magnesia. When constipation is produced by it, bismuth can be administered with rhubarb or magnesia. Bismuth is one of the remedies most frequently employed in the treatment of the vomiting of teething children, cholera infantum, and summer diarrhoea. Numerous combinations are employed : with pep- sin, when these disorders appear to depend on the condition known as apepsia, the discharges containing masses of undigested casein ; with rhubarb, when the symptoms are produced by undigested aliment, or when the stools are white and pasty ; with soda and chalk, when the stools are acid and excoriate the buttocks. In cases of vomiting of pregnancy, the vomiting of teething children, acidity, and pyrosis, ex- cellent results are sometimes obtained from bismuth and carbolic acid. r> Bismuthi subnitrat., 3 ii ; acid, carbol., gr. ij — gr. iv ; mucil. acacias, 3 j ; aquas menthas pip., § iij. M. Sig. : A tablespoonful for adults and a proportionate quantity for children three or four times a day. The diarrhoea of typhoid fever is restrained by bismuth in scruple to half-drachm doses. In chronic diarrhoea large doses of bismuth are beneficial and often curative, but thirty to sixty grains must be given every three or four hours. Equally large doses check the diar- rhoea of phthisis. In these doses, bismuth not only restrains the in- testinal discharges, but improves the appetite and the digestion. Bismuth is employed for a variety of purposes in the treatment of external maladies. It is a good application to the reddened surface of 144 RESTORATIVE AGENTS. the skin in cases of acne rosacea, and may be used as a cosmetic in this mortifying disease. The author has seen excellent results from the free application of bismuth in cases of eczema when there was much serous exudation. Under the crusts thus formed healing pro- ceeded satisfactorily. In intertrigo and in the erythema which occurs about the genitals of infants, dusting the affected surface with bis- muth soothes the j)ain and promotes healing. Bismuth is one of the numerous applications to the eye in cases of chronic conjunctivitis and granular lids. It is also used as an injection, mixed with mucilage, or with cocoa-butter in the form of a suppository, in chronic gonorrhoea and in gleet, and in leucorrhoea. fy Bismuthi subnitrat., gr. vj ; hy- drarg. chlor. cor., gr. ss ; tinct. camphorae, ttl jss ; aquae ad § j« M.

Arsenic in solution is better for internal administration than the solid arsenious acid, and, of the three solutions (official) mentioned above,, Fowler's is the best. Arsenious acid, when administered in ARSENIC. 145 the solid form and at short intervals, may act with unexpected vio- lence. When a course of arsenic is begun, large doses should be pre- scribed, and the quantity administered should be regularly reduced. In this way chronic arsenical poisoning is avoided. When continually increasing doses are given, the arsenic accumulates, and toxic symp- toms are quickly induced. As a rule, unless very small doses are pre- scribed, arsenic should be taken after meals. Some subjects are soon seriously affected by even small doses of arsenic. For this reason, when the idiosyncrasies of the patient are unknown, it were better to make tentative experiments with a few small doses before beginning with large ones. A few drops of laudanum given with arsenic will enable it to be better borne by some susceptible subjects. Antagonists and Incompatibles. — The salts of iron, magnesia, and lime, and astringents, are chemically incompatible. The arseniate of iron, although not actively so, does cause toxic symptoms if con- tinued in full medicinal doses. The hydrated sesquioxide of iron, freshly precipitated) and in a soft magma, is the antidote to arsenic in solution. About eight grains of the antidote are required for each grain of the poison swallowed. As the hydrated sesquioxide of iron is harmless, it should be given in teaspoonful to tablespoonful doses, every few minutes. In every case of poisoning by arsenic, prompt efforts to secure evacuation of the contents of the stomach are neces- sary. Large doses of the antidote may be given with the emetic em- ployed. In the absence of the hydrated sesquioxide of iron, magnesia, chalk, and lime-water may be given freely. These agents act in part, and probably chiefly, mechanically, by enveloping the particles of ar- senic, and so hindering absorption. It is held by some that freshly precipitated hydrate of magnesia is more effective as an antidote than the hydrated sesquioxide of iron. Large draughts of oil, milk, and substances containing mucilage, by protecting the mucous membrane, render important service in cases of arsenical poisoning. Dialyzed iron, later experiences show, is quite as efficient as the hydrated sesqui- oxide, and is always ready. It is an important point to favor rapid elimination of the poison when the patient survives the acute symp- toms. This is accomplished by the use of diluent drinks, skimmed milk, slightly alkaline mineral waters, etc. Synergists. — All those agents which promote constructive meta- morphosis are synergistic to arsenic. Physiological Actions. — Applied to the tissues, arsenic excites violent inflammation and causes destruction of the part ; it is, there- fore, an escharotic. Great pain attends its action. In consequence of the high degree of inflammation which it excites, when applied in suf- ficient strength, absorption does not follow its local use, but weak ap- plications may excite dangerous symptoms by diffusion into the blood. 10 146 RESTORATIVE AGENTS. Symptoms of poisoning follow the inhalation of arsenical fumes. Numerous instances have occurred in which wall-papers colored with arsenical pigments have poisoned the occupants of an apartment. Gar- ments covered with aniline dyes, fixed by arsenical mordants, have induced local ulcerations and systemic symptoms from absorption of arsenic. Applications to a large portion of even the unbroken integu- ment, and to ulcerated surfaces, have, in numerous instances, excited dangerous symptoms, and have produced fatal results. That arsenic, wherever applied, manifests a selective action on the mucous mem- brane of the respiratory and digestive tracts, is a curious fact. Arsenic, in small medicinal doses, promotes the appetite and diges- tive functions, and improves the body nutrition. It increases secretion of the gastro-intestinal mucous membrane, and hastens the peristaltic movements. Arsenic diffuses into the blood with facility. It probably enters into combination with the red blood-globules. It certainly lessens the excretion of carbonic acid, probably also of urea ; in other words, it checks the retrograde metamorphosis. It stimulates the cerebral functions and induces a feeling of well-being, and in some subjects decided mental exhilaration. In larger doses, yet not in quantity to produce acute poisoning, and when full medicinal doses have been administered for a lengthened period, arsenic causes more characteristic physiological actions than are described above. As regards the digestive organs, the following phenomena occur : A metallic taste ; increased flow of saliva ; nausea, vomiting of glairy mucus, epigastric pain, and soreness ; diarrhoea, tenesmus, and sometimes dysenteric stools. As regards the circulatory and respiratory organs : the action of the heart becomes irritable and feeble, palpitations, cough, oppressed breathing, oeclema of the eyelids, general oedema, and albuminuria occur. As regards the skin : itching of the eyelids, urticaria, eczema, pityriasis, psoriasis, and falling out of the nails and hair. As regards the nervous system : disorders of motility — trembling, stiffness, and contraction of the joints, disorders of sensibility, herpes zoster. Notwithstanding the effects above described are so frequently ob- served to follow the use of arsenic, it is undoubtedly true that a cer- tain degree of tolerance may be established when doses in themselves toxic can be taken with impunity. This state has been produced in a course of the legitimate administration of arsenic, and has been wit- nessed on a considerable scale among the arsenic-eaters of Styria and Southern Austria. The arsenicophagi begin the habit of arsenic-eat- ing at an early age, and become habituated to the use of enormous doses. They find that this practice is serviceable in several respects : they improve in bodily condition, gain in breathing-power, and be- come stronger and more pugnacious, and also more salacious. Wben arsenic is swallowed in sufficient quantity to cause the symp- ARSENIC. 147 torns of acute poisoning, the phenomena produced are of two kinds — gastro-intestinal irritation and cerebral effects. The former is much the more common. The following are the symptoms of the gastro-in- testinal form of acute arsenical poisoning : Burning at the epigastrium and radiating thence over the abdomen ; violent and uncontrollable vomiting ; great dryness of the mouth and fauces ; intense thirst ; intestinal irritation, bloody and offensive stools, retracted abdomen ; strangury, priapism, suppression of urine or bloody urine, and in fe- males menorrhagia ; rapid and feeble action of the heart, oppressed breathing ; great agitation and restlessness ; shrunken features, cold breath ; involuntary evacuations ; collapse — consciousness being re- tained to the last. In the cerebral form of acute poisoning, without any symptoms of gastro-intestinal irritation, the patient is suddenly put into a condition of profound insensibility and coma, not unlike extreme opium narcosis. Recovery from the effects of acute arsenical poisoning is rarely complete. For a long time afterward a considerable degree of gastro- enteric irritability will persist, and life may at last be lost from the continued operation of this pathological state on the function of nu- trition. An irritable state of the skin and stiffness of the joints may also continue for some time, and paralysis may supervene, accompa- nied with neuralgic pains, numbness, formication, etc. The changes found after death in the gastro-intestinal mucous membrane are those due to an irritant : deep redness, erosions, ecchy- moses, and softening. These alterations are also produced when toxic effects are caused by the external application of arsenic. More or less redness of the tracheal and bronchial mucous membrane and conges- tion of the lungs have been observed. It must not be forgotten that arsenic has caused a fatal result without producing any gastro-intesti- nal lesions except some uncharacteristic redness. Fatty degeneration of the liver, kidneys, spleen, and other organs, has been observed in cases of acute poisoning, even when the symptoms have existed for a few hours. The icterode hue of the skin and the albuminuria which occur in the course of chronic arsenical poisoning are probably due to fatty degeneration of the liver-cells and of the renal epithelium. Arsenic, although like other mineral poisons it tends to accumulate in the system, is nevertheless eliminated with considerable rapidity. If the patient survive a week after the ingestion of a toxic dose, it is difficult to detect it in the body after death. If the poison is retained and death ensues before elimination can take place, it undoubtedly re- tards putrefaction. Arsenic is eliminated by various organs — by the liver, intestinal canal, kidneys, and bronchial tubes — and some of the symptoms produced by it probably have their origin in the local effect of the poison on the channels of excretion. The quantity of arsenic required to produce a fatal effect varies ac- 148 RESTORATIVE AGENTS. cording to the state of the stomach and the susceptibilities of the pa- tient. Ounces have been swallowed without producing even serious symptoms, because promptly rejected by vomiting. When the stom- ach is full of food, absorption is slow and vomiting is easily induced, and hence a toxic dose may not under these circumstances produce any of the phenomena of poisoning. A half -grain of arsenious acid has caused symptoms of poisoning (Taylor), and, according to the same authority, from two to four grains may prove fatal to an adult. Much depends on the idiosyncrasies of the individual, which, as has been stated above, differ greatly in different persons. These facts should not be forgotten in prescribing strictly medicinal doses of ar- senical preparations. From this general survey of the effects of arsenic, we may properly proceed to study the results of more minute investigations. Yirchow has pointed out the similarity in the post-mortem appearances of arsenic and of cholera. The cholera-fungus of Klebs and the characteristic rice-water contents of the intestinal canal were not wanting to com- plete the resemblance. Hoffman has since fully confirmed these ob- servations. Croupous exudations are sometimes encountered in the stomach and intestines, and crystals of arsenic have been found im- bedded in the false membrane. This result is due to the action of arsenic when swallowed in powder, and is not produced w T hen the poison is taken in solution (Filehne, Lesser). The gastro-intestinal in- flammation, present in a large proportion of cases, is due in part to the local action of the arsenic, in part to its selective action, but this fact does not justify the statements of Bohm and Unterberger that a larger dose of the poison is required to destroy life by the intravenous injec- tion than by the stomachal administration. Lesser holds with the authorities in general that arsenic, in common with other poisons, is more fatal by intravenous injection. In a small proportion of cases, as has been stated, gastro-intestinal inflammation does not occur, but the effects of the poison are expended on the nervous centers ; several hours after the ingestion of a large dose, delirium, followed by coma, and convulsions come on, and with these albuminuria, occasionally urinary suppression. The relation of the attacks of eclampsia to the albuminuria has not been settled. In still other cases the gastro-intes- tinal disturbance, the rice-water discharges, the collapse, simulate the algid stage of cholera. The remarkable fall in the blood-pressure of the abdominal vessels produced by arsenic certainly throws light on these phenomena (Bohm and Unterberger). The experiments of Sklarek have demonstrated that arsenic decid- edly impairs sensibility, leaving the motor functions untouched. In the human subject, however, as the result of acute poisoning, and sometimes after the acute symptoms have subsided, certain paralyses develop. They may be preceded by numbness and tingling, and may ARSENIC. 149 be accompanied by contractures which disappear in curable cases, and remain permanently in incurable cases. The paralysis may be limited to a single member, and when several are thus affected the usual form of paralysis is paraplegia ; but all four members may be thus disabled. The rectum and bladder are not affected (Christison). These clinical observations by Christison are confirmed by the researches of Ringer and Murrell, who have shown that Sklarek's statements were incorrect, and that motor paralysis precedes sensory paralysis in the frog poi- soned by arsenic. (See Ponteland Poisoning Cases, " Lancet," Sep- tember, 1866.) The effects of arsenic on the circulation are not the same in cold and warm blooded animals, for, according to Sklarek, in the former the action of the heart is slowed, then arrested, while in the latter the action of the heart persists after the cessation of respiration (Bohm and Unterberger, Lesser). This fundamental difference in the action of arsenic on the two classes of animals requires us to accept with caution the observations made on the vaso-motor system of the cold- blooded. It has been pretty definitely ascertained that arsenic causes a fall in the blood-pressure, which is especially strong in the abdomi- nal blood-vessels (Bohm and Unterberger). A fact of great importance, first ascertained by Saikowsky, is the fatty degeneration of the liver, kidneys, heart, and other organs. The case of Grohl and Mosler, reported in the same volume of Virchow's " Archiv " containing Saikowsky's paper, is confirmatory more or less completely of the observations in the latter. They found, as their figures well exhibit, fatty degeneration to a greater or less extent in the glandular epithelium of the intestinal canal, and less conspicuous evidences of the same change in the kidneys, the liver, and the muscu- lar tissue of the heart. As the extent of the change is determined largely by the duration of the case, when death occurs in a few hours, or in a day or two, little alteration is discernible. The effect of arsenic on the function of nutrition is as yet involved in doubt. It is a recognized fact that arsenic promotes constructive metamorphosis when administered in medicinal doses. It has been ascertained by Saikowsky that it arrests the formation of glycogen by the liver, and C. Schmidt has shown that it lessens the excretion of carbonic acid and urea. Although doubt has been thrown on these statements, they seem to be supported by the observations of Lesser on the temperature, which has been constantly and considerably de- pressed under the action of lethal doses. The effect of arsenic in lowering the functional activity of the respiratory center is a fact which supports the same view, for a diminution in the quantity of oxy- gen admitted to the blood must necessarily lessen the rate of oxidation. On the other hand are the adverse experiments of Kassel, a medical student under Prof. Gathgens, and Gathgens himself, which appar- 150 RESTORATIVE AGENTS. ently demonstrate an actual increase in the amount of urea excreted. Arsenic has an anti-fermentative action ; but it is not universally destructive of the minute organisms on th& presence of which the various fermentations are dependent. Thus it is poisonous to Torula cerevisice and to some micrococci, but not to all, and it does not impair the activity of certain animal ferments, as pepsin, pancreatin, etc. (Johannsohn, Schafer, and Bohm). On the trophic system it acts as a depressant when taken in considerable quantity. The dust from arsenical wall-papers has induced a cachectic state, accompanied by headache, vertigo, and tinnitus (Donkin). Aniline dyes fixed by a mordant of arsenic have excited ulceration of the nails, phlegmon of the hands, and anaesthesia and paresis of the extremities (Clemans). Therapy. — The preparations of arsenic are applicable to the treat- ment of the diseases of those tissues upon which it has a selective ac- tion. "No remedy is more useful than arsenic in the so-called irritative dyspepsia, manifested by these symptoms : a red and pointed tongue, poor appetite, distress after meals, the presence of the food causing intestinal pain, colic, and the desire to go to stool. Drop-doses of Fowler's solution, given before meals, quickly relieve this state of things. The effects of the arsenic are frequently favored by the con- joint administration of a little laudanum. In some cases of the vomiting of pregnancy, a drop of Fowler's solution given before each meal will afford astonishing relief. The particular indications for its use are these : vomiting of food, followed by retching and straining, the vomited matters being streaked with blood, or blood alone being thrown up ; these symptoms accompanied by gastralgia and pain between the scapulae. The vomiting of chronic gastric catarrh, especially the alcoholic form, is relieved by one or two drops of Fowler's solution taken before meals. It effects a cure in these cases by relieving the morbid state of the mucous membrane on which the vomiting depends. Arsenic is also very beneficial in these small doses in chronic ulcer of the stomach. It checks the vomiting, relieves the pain, and improves the appetite for food. It is not equally effective in the acute ulcer. Although ar- senic exercises but little influence over the progress of these cases, it is very serviceable in cancer of the stomach, by diminishing the pain and checking the vomiting. Gastralgia and enteralgia, when idio- pathic, are sometimes made to disappear in a very surprising manner by the same remedy, but there are no certain indications of the kind of case to which it is best adapted. In the treatment of stomach-disorders, only small doses of arsenic are admissible. Large doses, by creating an irritation of the gastric mucous membrane, will only defeat the end in view. That form of diarrhoea which consists merely in an intolerance of ARSENIC. 151 the presence of food, an evacuation of the undigested aliment taking place soon after it is swallowed, is cured by arsenic. Chronic diar- rhoea and dysentery (entero-colitis), especially when dependent on the changes induced by chronic malarial infection, are often greatly benefited by the same remedy. In these cases, two drops of Fowler's solution with five drops of laudanum should be given before meals. Attention to the diet is, of course, imperative. Constipation, when due to deficient secretion and dryness of the faeces, is sometimes over- come by small doses of Fowler's solution. Arsenic is one of the numerous remedies proposed for the treat- ment of epidemic cholera. It is a curious circumstance, first demon- strated by Virchow, that some cases of acute arsenical poisoning are not distinguishable by their symptomatology or morbid anatomy from cases of epidemic cholera. Arsenic has been used with success in the treatment of the jaun- dice due to catarrh of the bile-ducts succeeding to catarrh of the duodenum. It seems to the author to be better adapted to cases of jaundice of malarial origin. Excellent results are obtained by the persevering use in small doses of arsenic in cirrhosis. As arsenic tends to accumulate in the liver, and as it produces fatty degeneration of this organ, the curative effect in the above-named disorders may depend on this selective action. There is no doubt that arsenic promotes in a very decided manner the constructive metamorphosis. It is one of the most valuable agents which we possess in the treatment of chlorosis and anaemia. It is es- pecially adapted to those cases in which iron does not agree or fails of effect. The efficiency of iron in these disorders is much increased by combination with arsenic. Cases of acute coryza and hay-asthma are often decidedly relieved by this remedy. Chronic catarrh of the broncho-pulmonary mucous membrane, emphysema, sclerosis of the lungs, are maladies in which arsenic, long used in ordinary medicinal doses, is capable of effecting considerable amelioration. We have no single drug of equal utility in the chronic forms of fihthisis, but it is not serviceable in caseous pneumonia. It is said, and this statement corresponds to the author's observation, that, when there are much hectic and rapid disintegration of the pulmonary tissues, arsenic is not beneficial. Besides the stom- ach administration of arsenic in the above-mentioned maladies of the respiratory organs, it is used with advantage by the process of fumi- gation. The following is the formula of Trousseau for arsenical cigar- ettes : Arsenite of potassa 15 grains. Distilled water 1 ounce. Unsized white paper is thoroughly moistened with this solution, dried and cut into twenty equal parts, and each part rolled into a 152 RESTORATIVE AGENTS. cigarette. Two or three of these are smoked daily for the relief of chronic bronchitis, emphysema, spasmodic asthma, phthisis, hay-asth- ma, etc. The arseniate of soda may be used in the same way, and under the same conditions ; for example, take a half -drachm to one drachm of arseniate of soda, one ounce of distilled water, and moisten a bit of unsized paper with the solution, so that every piece of a given size shall contain a determined quantity of the arsenic, ordinarily from one fourth to one grain. When the cigarette is lighted, the pa- tient inhales the smoke by a single inspiration, and this inhalation is practiced three or four times a day. In cases of acute and chronic coryza, great advantage is obtained by snuffing into the nares the fumes of arsenical cigarettes. The arsenite of antimony, according to Dr. Lucien Papillaud, is especially serviceable in pulmonary affections. When, in consequence of feebleness of the heart, there are present short breathing on making slight exertion, and oedema of the feet and ankles, especially as these symptoms occur in old people, arsenic is in- dicated. Attacks of angina pectoris may be lessened or prevented by the persistent use of arsenic in the interval. Certain disorders of the nervous system are greatly benefited by the use of arsenical preparations. The author has seen it extremely useful in cerebrcd congestion, for the treatment of which it was origi- nally recommended by Dr. Lemare-Picquot. It is indicated when there are commencing atheroma of the cerebral vessels, sluggish venous cir- culation, puffiness of the eyes, tendency to drowsiness, and intellectual torpor. In the melancholy and hypochondria of the aged, it gives great comfort, and frequently entirely dispels the gloomy fancies which take possession of the mind under these circumstances. The arsenic acts most favorably when combined with minute doses of opium ; viz., two drops of Fowler's solution, with three to five drops of tincture of opium, given three times a day. Arsenic is one of the remedies successful in the treatment of neuralgia. Generally its curative influence is indirect, and exerted through the improvement in the bodily nutrition which fol- lows its administration. It is directly curative, however, in the cases of hemicrania, and other neuralgim of malarial origin, but it holds a place strictly secondary to quinine in these affections. It is certainly one of the most effective remedies which we possess in the treatment of chorea. In this disease, large doses — five minims ter in die — must be given. Young subjects, it should be remembered, bear large doses of arsenic, relatively, better than adults. Cases of epilepsy have been reported cured by arsenic, but these were probably instances of epilepti- form vertigo caused by stomach-disorder, in which this remedy is un- doubtedly of great utility. Charcot has found the subcutaneous injec- tion of Fowler's solution of real value in paralysis agitans. The same expedient has succeeded in local chorea and histrionic spasm. The in- jection should be made into the affected muscles, whenever practicable. ARSENIC. 153 Arsenic produces, in the course of its medicinal administration, affec- tions of the skin, and notably those dependent on an unknown state of the trophic nerves. In the treatment of various skin-affections we avail ourselves of this physiological fact, and set up by means of arsenical preparations a substitutive action in the skin. It follows, that arsenic will not be serviceable in acute affections of the skin, and experience demonstrates that, whenever active cell-proliferation is taking place, arsenic is contraindicated. It is most serviceable when the affection of the skin is superficial in its seat — in the epidermis and the superfi- cial layers of the derma. In cases of psoriasis much good may be ex- pected from it, but, the more chronic the disease, the more beneficial is it. When the arsenic begins to exert an influence on psoriasis, the skin appears more inflamed, but this is an evidence that the curative action is taking place, and the remedy should then be persisted in. Acute eczema is rather exasperated by arsenic, but chronic eczema, especially eczema squamosum, is often greatly benefited by it. When eczema infests the vulva, anal region, and scrotum, arsenic is said to be useful, but its efficacy in these cases is largely determined by the chro- nicity of the attacks. Pemphigus is an affection of the skin which, as was more particularly shown by Mr. Hutchison, is curable by arsenic, bat the more chronic the disease the more certainly beneficial the remedy. In old cases of acne, especially acne rosacea, arsenic is some- times serviceable, but it is often very disappointing. The author has not observed much good to follow the use of arsenic in the acne which occurs at puberty and for some years subsequently. In all cases of acne the strictest attention to diet and a proper hygiene is very im- portant. Arsenic given with bromide of potassium lessens or prevents the very disfiguring acne which appears in the course of the adminis- tration of that agent. Furuncle (boils) is successfully treated by the long-continued use of arsenic. This practice is strongly urged by Dr. Delioux de Savignac. A succession of boils is the indication for the use of this remedy. In the treatment of skin-affections, Fowler's solution is the arsenical preparation most frequently employed. The commencing dose need not be larger than five drops three times a day, given after meals. It is better to commence with the maximum dose, and to diminish the amount gradually. As arsenic needs to be administered for a long time in skin-diseases, such toxic symptoms as irritation of the eye- lids, puffiness of the eyes, and epigastric pain and soreness, are apt to arise. These symptoms are indications for the use of laxatives, and for a reduction in the dose of the remedy, but not for its entire sus- pension. In order to prevent relapses, the use of arsenic should be continued, in diminishing doses, for some time after the entire disap- pearance of the eruption. Arsenic is not serviceable in skin-diseases of syphilitic origin. In 154 RESTORATIVE AGENTS. very chronic cases of this kind the compound solution of arsenic, iodine, and mercury — Donovan's solution — is sometimes very effective, but the curative effect is here due to the iodine and mercury, rather than to the arsenic. Arsenic is very useful in a certain form of chronic arthritis. The cases to which it is adapted are those in which the joints become tumid and stiff and painful in consequence of a peculiar state of the nervous system ; indeed, the condition is one allied to neuralgia, the trophic nerves being involved. This is a malady very different from that kind of chronic rheumatism or rheumatic gout which is accompanied by nodosities of the joints, in which arsenic has been recommended, but over which, according to the experience of the author, it exerts no control. Arsenic has seemed to the author remarkably beneficial in diabetes of hepatic origin. It has also been found useful by Johannsohn. Brunton reports good results from its administration in albuminuria, apparently due to defective digestion of albumen. Amenorrhoea, when due to functional inactivity of the ovaries, and menorrhagia, when produced by anaemia, are equally benefited by the preparations of arsenic, especially when combined with iron. /Sper- matorrhoea, if dependent on a weak and relaxed state of the seminal vesicles, and functional impotence, are sometimes greatly improved by full doses of the arseniate of iron. It is often advantageous to com- bine the arseniate of iron and ergotine, as follows : IjL Ferri arseniat., gr. v ; ext. ergotae, 3 ss. M. Ft. pil. no. xxx. Sig. : One night and morning. Next to quinine, arsenic has the most important position in the treatment of malarial fevers. It may be used to prevent the recur- rence of attacks of ague when quinine for any reason is not admissible. As regards acute malarial toxaemia, arsenic is more useful as an ad- junct to quinine than as the sole remedy. The treatment of acute cases may be formulated as follows : large doses of quinine to interrupt the paroxysms, and at the septenary periods ; arsenic given daily to pre- vent relapses. It plays a more important role in chronic malarial dis- eases. As has been shown by Boudin, arsenic diminishes the engorge- ment of the spleen. The author has witnessed the rapid disappearance of malarial jaundice, and the cure of the alterations in the glandular appendages of the intestinal mucous membrane, under its use. It is most useful generally to combine iron with arsenic in the chronic form of malarial disease. $ Mas. ferri carbon., 3 j ; acidi arseniosi, gr. j. M. Ft. pil. no. xx. Sig. : One three times a day. $ Quininse sulph., 3ij ; ferri sulph. exsic, 3 j ; acidi arseniosi, gr. j. M. Ft. pil. no. xx. Sig. : One three times a day. Boudin justly insists upon abundant ali- mentation during a course of arsenical treatment of intermittents, and, with a view of preparing the digestive organs, administers a prelimi- ARSENIC. 155 nary emetic to relieve the stomach of the embarras gastrique. Arsenic has also been used as & prophylactic against malarial infection, and as a remedy for various intermittent diseases due to malarial influence. The author has seen excellent results from the use of small doses of Fowler's solution three times a day in typho-malarial fever. When there is much diarrhoea, a few drops of tincture of opium should be added to each dose of arsenic. In doses of half a drop to one drop of Fowler's solution, the tongue cleans, the skin becomes moist, and the delirium lessens in a most remarkable manner, sometimes. When arsenic is used alone in the treatment of intermittents, large doses are necessary. Ten drops of Fowler's solution may be given after meals to adults, but in a few days — three, four, or five, according to the sus- ceptibility of the patient — the dose must be reduced two drops each day until four drops are reached. If the stomach does not become disordered, slight irritation of the conjunctivae and puffiness of the eyelids may be disregarded. There can be no doubt that the long-continued use of small doses of arsenic exercises a favorable influence over the course and progress of epithelioma. It has appeared, indeed, to be useful in scirrhus, es- pecially as this morbid process manifests itself in the stomach. Ro- dent ulcer, which is closely allied in its nature to epithelioma, is also improved by it. With the internal use of the arsenical preparations may be conjoined the local applications of arsenious acid. Many phy- sicians, notably Dr. Atlee, of Philadelphia, entertain the belief that the long-continued use of arsenic retards the growth of uterine cancer. It appears to the author to be certain that arsenic is useful in epithe- lioma, but he regards it as improbable that it exerts a curative influ- ence over the other forms of cancer, although it alleviates some of the distress experienced by the subjects of cancer of the stomach. Bill- roth reports a case of multiple lymphoma cured by the use of arsenic. External Uses of Arsenic. — An arsenical paste having the follow- ing composition is used to destroy the sensibility of a carious tooth : arsenious acid, ij ; sulphate of morphia, j ; sufficient creosote to make a paste. A small quantity of this is applied by a bit of cotton- wool to the carious portion of the tooth. Arsenious acid is sometimes employed to destroy cancerous growths. But, as it is extremely painful, and as the danger of ab- sorption is great, other escharotics, as, for example, the chloride of zinc, are generally preferred. When it is used, the operator should be careful to employ an arsenical paste of sufficient strength to set up a limiting inflammation, and thus prevent absorption. From one sixth to one fifth of arsenious acid is the proper proportion, and it may be mixed with calomel, starch, or other impalpable powder. If the sur- face to be destroyed is large, a portion of it should be submitted at a time to the action of the escharotic. Poultices should then be ap- 156 RESTORATIVE AGENTS. plied until the slough separates, when a healthy granulating surface is obtained. The excessive pain caused by the escharotic may be much alleviated by combining morphine and carbolic acid in the ar- senical paste, or by the use of morphine hypodermatically until the escharotic action ceases. An arsenical paste prepared as follows is sometimes used as a de- pilatory : quicklime, § ss ; yellow sulphide of arsenic, grs. xx ; starch, 3 ij. Sulphide of barium and oxide of zinc is a more efficient combi- nation. Esmarch's caustic is composed of : Arsenious acid, one part ; morphia sulph., one part ; calomel, eight parts ; and pulv. acaciae, forty-eight parts. Mix. Sprinkle thickly every day on a surface either raw or denuded of cuticle by a blister. In addition to the above local uses of arsenic, the results achieved by its hypodermatic injection should be mentioned. Dr. Radcliffe was the first to employ this practice in cases of local chorea of the head and neck, and in histrionic spasm. In these affections Fowler's solu- tion or Pearson's, in doses of two to ten minims, diluted with an equal measure of water, is thrown into the affected muscles daily, sometimes curing after some weeks of treatment. In obstinate cases of general chorea the subcutaneous injection of arsenic is now practiced, with good effects, a cure resulting more speedily than by the stomachal method of administration. Arsenic used by this method has proved to be the most effective remedy for lympadenoma. Authorities referred to : Gathgens, C. Zur Kenntniss der Arsenivirkungen. Centralblatt f. d. med.

The sulphate of iron, and the sil- ver and lead salts, are incompatible with gentian. The infusion of coptis is not affected by the salts of iron, but is precipitated by the nitrate of silver and acetate of lead. Therapeutically, all those agents which promote waste or destructive metamorphosis are opposed to the action of the simple bitters. Stneegists. — Iron, the mineral acids, pepsin, bismuth, etc., are synergistic to the bitters, and under some circumstances the alkalies promote their therapeutic action. Physiological Actions. — The simple bitters increase secretion from the mucous membrane. In the mouth they promote the flow of saliva, and in the stomach they appear to stimulate the production of gastric juice, and also of gastric mucus. It follows that an increase of digestive capacity is one result of their administration. The in- creased appetite which is observed from the use of the bitters is prob- ably due to two factors : the sense of bitterness which increases the THE SIMPLE BITTERS. 159 desire for food, and the improved digestive power which, enabling more food to be disposed of, postpones the sense of satiety. Further- more, the bitters, by removing morbid states of the intestinal mucous membrane, favor assimilation. More food being taken and more thoroughly digested, it is obvious that the bitters promote construc- tive metamorphosis. The blood is indirectly enriched by them, and the tissues are consequently improved in their nutrition. The simple bitters are accordingly usually classed with tonics. To these effects of the simple bitters as a group, it is necessary to add that the active constituents of some of them have been studied in detail. Berberine, which enters into the constitution of several, is possessed of some antiseptic and antiperiodic power, but is not active from the physiological point of view. Quassin has recently been studied by Dr. Campardou, and his observations published in a special memoir. There are, however, no new facts produced. Quassin, as might be supposed from its origin, acts after the manner of the bitter tonics ; it increases the appetite, and promotes the digestive functions by stimulating the secretions of the gastro-intestinal mucous mem- brane, and the contractility of the muscular fiber of the intestine. In an overdose quassine causes the local and systemic symptoms of an irritant poison. Although these remedies, used judiciously and for a short period, undoubtedly promote the constructive metamorphosis, yet their long- continued use will produce gastric catarrh, decrease the flow of healthy gastric juice, and impair digestion. Thekapy. — An infusion of coptis has much reputation in Xew England as a remedy in aphthae, psoriasis of the mucous membrane, ulcers, and epithelioma. Used as a gargle, it is serviceable in ulcera- tion of the tonsils. A few drops of the tincture of calumba, or a teaspoonful of the in- fusion, will sometimes greatly relieve the vomiting of pregnancy, and is also occasionally efficacious in sea-sickness. The simple bitters are especially indicated in atonic dyspepsia, and in chronic gastric catarrh. They are useful in this state of things : pain after food, slow diges- tion, constipation alternating with diarrhoea. Calumba is the mildest, and may be borne when quassia and gentian disagree. According to Wilson Fox, " calumba holds the chief place in point of therapeutic value as a remedy which can be safely employed when others of the class would be too irritating." When there are much relaxation and torpor, quassia is very useful as a stomachic tonic. Sometimes an ex- temporaneous cold infusion of quassia is used, made by filling over- night with cold water a quassia-cup — a goblet turned out of quassia- wood. When constipation exists in cases of atonic dyspepsia, good results are obtained by a combination of gentian with senna, as in the formula already given. The compound tincture of gentian is an ex- 160 RESTORATIVE AGENTS. cellent vehicle for the administration of cod-liver oil, and contributes to its digestion and assimilation. The infusions of gentian, calumba, and quassia are usefully em- ployed as vehicles for the administration of acids and alkalies in cases of acidity and deficient supply of gastric juice, under the rules given in the articles on acids and alkalies. In convalescence from acute diseases, the simple bitters, especially gentian and calumba, are employed to promote the appetite and diges- tion, and thus to aid in the process of constructive metamorphosis. In the diarrhoea which is due to relaxation of the mucous mem- brane, and is not dependent on inflammation, the tincture of calumba is often useful. The author has obtained good results from the use of tincture of calumba combined with opium in the treatment of an irritable state of the intestinal mucous membrane, indicated by these symptoms : Soon after taking food, the occurrence of pain referable to the small intestines, nausea, loose evacuations containing undigest- ed aliments, and followed by weakness and depression. ^ Tinct. ca- lumbae, 3 xv ; tinct. opii deodor., 3 j. M. Sig.: A teaspoonful in a wineglassful of water before meals. Calumba is also serviceable in the relaxation of the bowels succeeding to acute affections of the in- testinal mucous membrane. The infusion of quassia is one of the most effective injections for the destruction of the ascarides vermiculares which infest the rectum. The stomach administration of simple bitters undoubtedly hinders the development of intestinal worms, probably by correcting a morbid state of the mucous membrane. In the treatment of intestinal para- sites much good, therefore, is derived from the use of bitters, admin- istered with the view of restoring normal digestion. According to Wood, the remedy most effective to remove and " permanently cure a disposition to the accumulation of flatus in the bowels is an infusion made with half an ounce of calumba, half an ounce of ginger, a drachm of senna, and a pint of boiling water, and given in the dose of a wineglassful three times a day." The bitters are used as remedies in malarial fever. Although they exercise but little influence over the course of intermittent and remit- tent fever, they are useful in the form of infusion as vehicles for the administration of more active drugs. In the convalescence from mala- rial fever, and in chronic malarial poisoning, they are more actively beneficial as agents promoting constructive metamorphosis. The dog- wood, of all the bitters given in the above list, possesses the most positive antiperiodic qualities, and is considered by the physicians of Southern United States as next to quinine in efficiency. An excellent tonic combination of decided utility in chronic malarial disease is the following : Dogwood-bark, calumba, poplar (liriodendron), wild-cherry, of each six ounces ; boneset (eupatorium) and cayenne pepper, of each AROMATIC BITTERS. 161 four ounces. Mixed and sifted. Of the mixture a teaspoonful in cold or warm water, three or four times a day. A useful tincture to serve the purpose of a tonic, and as a remedy in malarial affections, may be prepared from the above combination of bitter tonics. AROMATIC BITTERS.

Composition. — A crystallizable principle, cascarillin, tannic acid, a volatile oil, etc. Actions and Uses. — These remedies possess the quality called tonic ; they invigorate digestion, and promote constructive metamorphosis. They differ from the simple bitters in containing aromatic constituents, and in being astringent to a greater or less degree, owing to the pres- ence of tannic and gallic acids. They are indicated in the same kind of cases as, and under similar conditions to, the simple bitters ; but they are supposed to have, in addition, some specific properties derived from their volatile and odorous constituents. Serpentaria is occasionally used as a stimulating tonic in typhoid and typho-malarial fevers. It is more frequently prescribed as a stimulant expectorant in capillary bronchitis, and in pneumonia of low grade, when carbonate of ammonia is combined with it. For- merly it was used locally to the throat, as a gargle in diphtheria, and 11 162 RESTORATIVE AGENTS. given internally as a stimulant, but it is now very rarely employed in such cases. Wild-cherry is an excellent stomachic tonic, and may well be used as a substitute for calumba in the class of cases to which the latter is considered specially applicable. It has long been held in great esteem in domestic practice, as a remedy in catarrhal states of the bronchial mucous membrane, and in phthisis. Owing to the prussic acid which its cold infusion contains — produced by the reaction between the amyg- dalin and emulsin — it exercises some influence over cough. That it has any special virtues in the treatment of phthisis is hardly to be credited. The sirup is much used as an ingredient in cough-mixtures. Authorities referred to : Porcher, Dr. Francis Peyre.

Extractum Eucalypti Fluidum. — Fluid extract of eucalyptus. Dose, in, x — 3 j. Eucalyptol. — Dose, in v — 3 ss. Usually prescribed in capsules, but may be given in the form of emulsion. Composition. — Eucalyptus contains a peculiar resin composed of three different resinous bodies, a volatile oil consisting of eucalyptol, turpene, and cymol, tannic acid, and a crystallizable fatty acid. Euca- lyptol is the most important of the constituents. Antagonists and Incompatibles. — Alkalies, the mineral acids, the salts of iron, mercury, lead, zinc, etc., are chemically incompatible. All agents promoting waste, or the retrograde metamorphosis of tissue, are therapeutically incompatible. Synergists. — The simple and aromatic bitters, hydrastis, cinchona, etc., camphor, turpentine, cubebs, copaiba, the essential oils and sub- stances containing them, are synergistic to or promote the therapeuti- cal actions of eucalyptus. Any of these remedies may, therefore, be prescribed in the same formula with eucalyptus. Physiological Actions. — Eucalyptus has a warm, aromatic, bitter, and camphoraceous taste, resembling somewhat the taste of cubebs. In the mouth it excites the flow of saliva, and leaves a hot, pungent, and rather disagreeable flavor. In the stomach it causes a sensation of warmth, and doubtless promotes the flow of gastric juice. The appetite and digestive power are increased under its use. Increased intestinal secretion, also, is one result of its administration, and hence EUCALYPTUS. 163 the alvine evacuations are rendered somewhat more copious and easy. In very large doses it causes a sense of weight and uneasiness at the epigastrium, odorous eructations and indigestion, followed by diarrhoea, the stools having the characteristic odor of eucalyptol. The essential oil is readily diffusible and enters the blood with facility, but what changes, if any, it induces in the blood are unknown. It increases the action of the heart, lowers the arterial tension, and induces a feverish state. The respiratory movements are accelerated. Wakefulness is caused by it in those of full health, and sleep in the weak and anaemic. The eucalyptol is eliminated by the skin, mucous membrane of the bronchial tubes, and by the kidneys, the secretions of these organs being increased by it, and they are impregnated with its odor. This is especially the case with the urine, which, after some days' adminis- tration, becomes most strongly odorous by the presence of eucalyptol. The vapor of eucalyptus, inhaled in large quantity, produces analo- gous effects to the internal administration, besides the more decided effects on the bronchial mucous membrane. Eucalyptus is a powerful diaphoretic. Therapy. — The decoction of the leaves is an efficient local appli- cation in the various forms of stomatitis, angina subacute and chronic, and tonsillitis after the subsidence of the acute stage. Eucalyptus is one of the most useful of the so-called stomachics in atonic dyspepsia, chronic gastric catarrh, and chronic intestinal ca- tarrh, but its use is contraindicated in inflammatory states. The form of vomiting and indigestion dependent on the presence of sarcina is relieved by this agent, which acts by destroying the vitality of this minute organism. That condition of the mucous membrane which favors the production of intestinal parasites is removed by eucalyptus. In the case of ascarides vermicular 'es, the remedy should be used by injection. Like the bitters, eucalyptus may be used to promote constructive metamorphosis, but it possesses more decided stimulant effects than these agents, by virtue of the eucalyptol. In convalescence from acute disease, in debility arising from defective assimilation, and in cachectic states generally, it is a serviceable tonic and stimulant. When the ac- tion of the heart is weak, it may be strengthened by eucalyptus. To women at the change of life who suffer from flatulence, palpitation of the heart, and sudden flushings of the face, it affords great relief, and often permanently removes these symptoms. Hysteria, chorea, asthma, and allied nervous states, when occurring in debilitated subjects, and cerebral ancemia, are benefited by eucalyp- tus. In asthma eucalyptus may be smoked in cigarettes with stramo- nium, belladonna, tobacco, etc. Its efficacy in the form of fumes is strongly stated by Maclean. The most important uses of this agent occur in the treatment of 164 RESTORATIVE AGENTS. catarrhal affections of the broncho-pulmonary mucous membrane. It is not adapted to acute affections or to recent inflammation, but to chronic cases accompanied by free muco-purulent expectoration. The author is able to confirm the observations of Gubler in reference to the great utility of eucalyptus in bronchorrhcea. It is an interesting fact, and probably explanatory of its therapeutical action, that eucalyptol is in part eliminated by the bronchial mucous membranes. In the same way eucalyptus is effective in the treatment of catarrhal states of the genito-urinary organs. Chronic desquamative nephritis, granular de- generation of the kidneys, pyelonephritis, and hydronephrosis, are im- proved by its cautious administration, but it should not be forgotten that, used too freely, or for too great a length of time, it will cause irritation and congestion of the kidneys, in the same way that turpen- tine, copaiba, and cubebs do. No remedy which the author has hitherto used has seemed to him so effective in chronic catarrh of the bladder as eucalyptus. The urine during its administration acquires a strong odor of eucalyptol, and to its local action on the mucous membrane is to be attributed the thera- peutical effect. Eucalyptus has been much praised as a remedy for intermittent fever. The evidence as to its utility is contradictory. As the result of his own observations, and after careful examination of the facts reported by others, the author concludes that eucalyptus is far inferior to quinine. It is certainly very serviceable in the convalescence from intermittent and remittent fevers, and in chronic malarial poisoning it has a high degree of utility. It can not take the place of quinine for the arrest of the paroxysms, or to prevent relapses at the septenary periods, but it is more useful than quinine to reconstruct the damages in the organs of assimilation caused by malarial infection. Externally, the tincture and the distilled water of eucalyptus are used as disinfectant applications to foul-smelling and ill-conditioned ulcers and wounds (Gimbert). The water of eucalyptus is recom- mended by Gubler as a vehicle for agents used by the hypodermatic method. The toxic influence of eucalyptus on the lower forms of life — cryptogamic and infusorial organisms — is the ground of its applica- tion for these purposes. As respects solutions of alkaloids for hypo- dermatic use, the water of eucalyptus prevents the development of the penicillium, which grows rapidly and at the expense of the alkaloid in solutions prepared with simple distilled water.

Fluid extract of Hydrastis. Dose, v\ v — f ss. Tinctura Hydrastis. — Tincture of Hydrastis. Dose, tti x — 3 j. Composition. — Hydrastis contains a peculiar principle, hydrastine or hydrastina, which crystallizes in four-sided prisms, white or color- less when pure, and having but little taste. Hydrastine, the alkaloid, should not be confounded with the eclectic preparation, hydrastin, which is composed chiefly of berberine. Much of the peculiar virtues of hydrastis is probably due to the alkaloid berberine, which is con- tained in it in the proportion of about four per centum. Both of these alkaloids unite with acids to form salts. Antagonists and Incompatibles. — The alkalies, tannic and muri- atic acids, are chemically incompatible with the preparations of hy- drastis. Muriatic acid precipitates berberine, and the so-called hy- drastine of the eclectic practitioners is nothing more than berberine muriate. In prescribing the tincture and fluid extract of hydrastis with other bitters, only those free from tannin should be combined in the same prescription. Synergists. — The vegetable tonics in general are synergistic to hydrastis, especially berberis vulgaris and calumba, both of which con- tain berberine. Physiological Actions. — The preparations of hydrastis have a decidedly bitter taste, and, like other bitters, promote the flow of saliva, and probably, also, of gastric juice. Increased appetite and digestive power result from its administration. It is, therefore, a stomachic tonic. It also increases secretion of the intestinal mucous membrane — its glandular appendages — and, there are good reasons for believing, promotes the flow of bile. As a result of this increase of secretion, the stools become softer and more frequent under its use, and it has hence been styled a laxative. The bodily condition, or constructive metamorphosis, is promoted by its administration. On the nervous system, hydrastis, especially the alkaloid hydrastine, has effects some- what like, but less than, those of quinine ; but it appears to be devoid of toxic power. Therapy. — Stomatitis, both mercurial and aphthous, is much im- proved by local application of the fluid extract of hydrastis. When 166 RESTORATIVE AGENTS. this preparation causes much smarting, it may be diluted with water. Follicular pharyngitis, chronic coryza, and even syphilitic affections of the mouth, throat, and nares, may be much benefited or even cured by the same application. It is said that five to ten drops of the fluid extract, taken by the stomach, will act favorably in the removal of the very troublesome affections named above, but the author is un- able to verify these observations. Hydrastis is very useful as a stomachic tonic, and may take the place of calumba in the treatment of atonic dyspepsia. A few drops of the tincture or fluid extract (five to fifteen) taken before meals, daily, for some time, will often cure chronic gastric catarrh, and remove the distressing headache which frequently accompanies this disease. It is one of the best remedies for the stomach catarrh of chronic alco- holism, and is probably the best substitute, if given in sufficient doses, for the alcoholic stimulant when its habitual use is to be abandoned. Catarrh of the duodenum is in a similar manner relieved by hydras- tis, but this agent has special utility in duodenal catarrh when accom- panied by catarrh of the gall-ducts and jaundice. Its use should, in these affections, be continued for some time. When a catarrhal state of the cystic duct — often resulting from or aggravated by catarrh of the duodenum — leads to inspissation of the bile and crystallization of the cholesterin, decided benefit accrues from the use of the prepara- tions of hydrastis. When constipation is dependent on deficient secretion, and the stools are dry and hard, it may be overcome by this remedy, but tor- por of the muscular layer of the intestine is not affected by it. Chronic catarrh of the intestine, even when it has proceeded to ulceration, is sometimes remarkably benefited by hydrastis. When the stools are very frequent and there is much pain, it is advantageous to combine a little opium with it. In fissure of the anus, haemorrhage from the rectum, and ulceration of the rectal mucous membrane, appli- cations of fluid extract of hydrastis to the affected parts promote heal- ing. The alkaloid hydrastine may be used as a substitute for quinine in many of the conditions for which the latter is now so frequently pre- scribed, viz., to promote appetite and digestion, and to improve assimi- lation in cases of debility, in convalescence from acute diseases, in the various cachexia?, especially the paludal. As a remedy for inter mittents, hydrastine ranks below quinine considerably. It should be given under the same regulations as those which govern the administration of quinine, to the physiological and therapeutical action of which it is closely allied. The hydrastine of the eclectics, which is really muriate of berberine, is also a remedy of value in intermittents. The fluid extract of hydrastis contains, of course, both alkaloids. In chronic malarial poisoning (paludal ca- CINCHONA. 167 chexia), hydrastine and berberine may be given with ferruginous prep- arations, as quinine is so frequently employed. It exerts the same power, though less in degree, which quinine has over enlarged spleen of malarial origin. The preparations of hydrastis are used with advantage in certain affections of the genito-urinary organs. In chronic JBrighfs disease, it appears to lessen the excretion of albumen. It diminishes the mu- cus in catarrh of the bladder. It is often the most efficacious remedy which we can employ in gonorrhoea after the acute stage has subsided, and in gleet. Especially in the latter has the author witnessed ex- cellent results from its employment. The local use of hydrastine, or of the fluid extract of hydrastis, should be conjoined with the internal administration. The author has seen no injection so frequently suc- cessful in gonorrhoea as hydrastine. $ Hydrastinse, 3 j ; mucil. aca- ciae, § iv. M. A half-ounce as an injection. Better, probably, the fluid extract, diluted properly or in combination, may be used for the same purpose. It is also a useful medicine in the treatment of sper- matorrhoea, prostorrhoea, or urethral leucorrhoea, when locally applied. Uterine and vaginal leucorrhoea, ulcerations, and erosions of the cervix uteri, are quickly improved by the topical application of the fluid extract of hydrastis, which may be used in an undiluted state. Unhealthy and sloughing sores, chancroid, old ulcers of the leg, are improved in character by the local use of this remedy. To pre- vent septic decompositions in wounds or cavities communicating with the external air, it may be freely used by local application and injec- tion. It has also been used, apparently with benefit, to the surface of cancerous growths ; but the only influence it can have in this disease is to relieve fetor by preventing decomposition.

Unofficial Salts of Quinine, — Kinate, tannate, citrate, acetate, tar- trate, phosphate, nitrate, hydrochlorate, arseniate, f errocyanate, picrate, etc. Salicylate of cinchonidine is a really useful addition to these salts. It has therapeutic property only second to the salts of quinine, and may be substituted for the latter in the treatment of malarial affections. Composition. — Cinchona is remarkable for the number and variety of the principles obtained from it, viz., five alkaloids, two simple acids, two tannic acids, and a resinoid substance. The most important alka- loid is quinine, which exists in all varieties of bark, but is most abun- dant in the yellow or calisaya bark. It occurs in combination with kinic and kino-tannic acids. Quinidine is an alkaloid isomeric with quinine, and may be used as a substitute for the latter in the same dose. It is less bitter than quinine, and its sulphate is more soluble in water. Cinchonine is found in greatest quantity in the pale barks. It unites with acids to form salts, of which the sulphate is most fre- quently used. Therapeutically considered, cinchonine has about half the strength of quinine. Cinchonidine is an alkaloid isomeric with CINCHONA. 169 cinchonine as quinidine is with quinine. Aricine, which has close anal- ogies with cinchonine, has been found in the aricia or Cusco bark. The alkaloids are combined in bark with the acids kinic and Jcino- vic, chiefly with the former. There are also two kinds of tannic acid, kino-tannic and Jcinovi-tannic, and a resinoid substance, kinovin. None of these have thus far been applied to therapeutical purposes, except kinic acid, which has been utilized to form a kinate of quinine, under the belief that a combination of quinine in its natural state would be more efficient as a remedy than as combined with a mineral acid. When the mother-liquor, left after the crystallization of the alka- loids, is evaporated, a black residue is obtained, which is called chinoi- dine. This contains amorphous quinine and cinchonine, and probably also quinidine and cinchonidine. It is a very efficient anti-periodic, and may be used with advantage as a substitute for quinine, in doses about twice as large. With regard to the quantity of the alkaloids contained in the barks, respectively, it may be stated that the three varieties — pale, yellow, and red — differ only in the relative proportions of their constituents. The pale bark contains most cinchonine, the yellow most quinine, and the red an equal proportion of each. Administration. — The alkaloids of bark are intensely bitter. Quinine being insoluble in the saliva, is less objectionable than its salts. The sweet principle of liquorice covers the taste of the cin- chona alkaloids. A sufficient dose of quinine may easily be inclosed in a chocolate caramel. The sugar-coated pill, when freshly prepared and by a reputable maker, is a convenient and suitable form for ad- ministration ; but by keeping it becomes hard and insoluble. The most active form is a solution, the quinine being dissolved by the aid of sufficient dilute acid. For hypodermatic use, the following formula may be followed : $ Quininae sulphat., 3 j ; morphinae sulph., gr. ss ; acid, sulphur, dil., n\, xl ; aquae destil., § j. M. Fil- ter. Sig. : Sixty minims contain seven and a half grains. Lente's solution is the following : 3 Quininae bisulph., grs. 1 ; acid, sulph. dil., TTJ, c ; aquae font., § j ; acid, carbol. liq., m, v. Solve. The qui- nine is dissolved by the aid of heat, and after filtration the carbolic acid is added. Antagonists and Incompatibles. — Substances containing tannic acid in a free state should not be administered with the infusum or decoctum cinchonas. The preparations of iodine (tincture and com- pound solution) are also incompatible, for they form insoluble com- pounds with the cinchona alkaloids. The alkalies, alkaline carbonates, and alkaline earths, should not be administered with the solutions of the alkaloids, because the latter will be precipitated. As an agent promoting constructive metamorphosis, cinchona and 170 RESTORATIVE AGENTS. its alkaloids are therapeutically antagonized by mercury, the iodides, the salts of copper, zinc, and lead. As Gubler has shown, morphine and quinine are antagonists in re- spect to their effects on the brain. As regards their action on the sympathetic system, on the heart, and on the temperature, quinine, and belladonna and its alkaloid, are antagonistic. Synergists. — All those agents which promote constructive meta- morphosis, as the bitters, the ferruginous preparations, arsenic, and the acids, are synergistic to cinchona. Physiological Actions. — The preparations of cinchona are known as " astringent bitters " : they contain, in addition to bitter principles, two tannic acids. As bitters they act as stomachic tonics ; that is, promote appetite, the flow of gastric juice, and the digestive power. Long continued, as is the case with all the other bitters, they set up a gastric catarrh, and digestion becomes painful and labored. They differ from the simple bitters in exercising an astringent action on the intestinal mucous membrane, and cause constipation. The red bark is more decidedly astringent than the yellow or pale bark. Since the time of Sir John Pringle, who made the first experiments on this point, cinchona has been known to possess antiseptic properties. The powdered bark, applied to unhealthy wounds, arrests putrefactive decomposition, and promotes healing. The alkaloids are destructive of the minute organisms, on the presence of which fermentative changes depend, and hence, when added to milk, urine, and other ani- mal fluids, will prevent decomposition (Binz, Herbst, Baxter, etc.). Quinine, the most active of the alkaloids, is not equally destructive of all minute organisms : some, it merely inhibits ; others, it kills. The bacteria of septic fluids resist its toxic action to a great extent, and are only inhibited by the largest quantity. When the crude bark is introduced into the stomach, the alkaloids are dissolved out by the acid gastric juice, in which they are freely soluble. Any portion of the bark, or of the alkaloids, escaping solu- tion in the gastric juice, probably, passes out with the other unabsorbed contents of the intestine. The alkaline reaction of the intestinal juices will cause precipitation of the alkaloids, which, forming insol- uble combinations with the bile-acids, will not be absorbed. From the stomach the alkaloids diffuse into the blood with facility. In the alkaline blood, it is probable that the alkaloids are held in solution by the carbonic acid (Kerner). No changes visible by the unassisted eye are discernible in the blood, for, notwithstanding the observations of the older writers, who affirm that the blood was dark and unco- agulable, the moderns deny the existence of such alterations (Briquet, Schwalbe). Quinine acts in a definite manner on certain constituents of the blood — on the haemoglobin, impairing its power to transport active oxygen or ozone, into which the ordinary oxygen of the air is CINCHONA. 171 converted. This is demonstrated in the following manner : Mix with old turpentine, that is, turpentine long exposed to the air, and there- fore holding ozone, some tincture of guaiacum ; if, now, some haemo- globin or a drop of blood be added to the mixture, the tincture of guaiacum assumes a blue color, the change of color being due to the oxidation of the guaiacum by the active oxygen or ozone contained in the haemoglobin (Hermann). The addition of certain substances, no- tably of quinine, prevents the reaction ; in other words, destroys the ozonizing action of the blood. Binz has shown that so small a quan- tity of quinine as one part to twenty thousand exerts this action to a considerable extent. As soon as the blood is withdrawn from the peculiar influence exerted by the walls of the blood-vessels, as was some time ago shown by Pfluger and Zuntz, its alkalinity begins to decline, and presently it exhibits an acid reaction. Correspondingly with the progress of this acidification, A. Schmidt has shown that the quantity of contained oxygen diminishes and the carbonic acid in- creases. These changes, leading finally to the death of the blood, are greatly retarded by the addition of quinine (Schulte, Binz, Ransone, Kerner). From these observations we draw the conclusion that qui- nine lessens the oxidizing or ozonizing function of the blood. Binz and his pupils have shown that quinine inhibits or lessens the activity of the white blood-corpuscles, and indeed destroys them, or arrests their production ; for, in cats poisoned by this agent, the num- ber of white corpuscles was found to be considerably less than in un- poisoned animals (Scharrenbroich, Martin, Jerusalimsky, Geltowsky). By all the observers just named, by Baxter, who made a series of very carefully conducted experiments, and by Cutter, it has been estab- lished that quinine inhibits the amoeboid movements of the white cor- puscles. These bodies, as other masses of protoplasm, are in con- stant motion, changing their form and appropriating the materials of their nutrition. Such movements are called amoeboid, and they are arrested by quinine, even in so small a quantity as one part to four thousand ; hence it is called a protoplasmic poison. Quinine has also the power to prevent or arrest the migration of the white corpuscles from the vessels. This Binz was the first to demonstrate, using the method employed by Cohnheim for exhibiting the phenomena. This is now generally conceded, although denied by Schwalbe ; but, as the observations of Geltowsky show, the quantity of quinine necessary to produce the result varies with the animal experimented on, and ranges from one part in four thousand to one part in eight hundred, outside of the body (Appert). No amount, short of a fatal dose, can affect the movements of the white corpuscles in the living warm-blooded animal, according to Geltowsky, who, therefore, holds to the same view as Schwalbe on this point. In opposition to the views of Binz must also be placed Schtschepotjaw, who has studied the effects of small quantities. 172 RESTORATIVE AGENTS. Quinine also affects the rate of movement of the heart. An impor- tant distinction exists between the action of small and large doses. It is a matter of daily observation that ordinary medicinal doses of qui- nine (from two to five grains) increase the action of the heart, while experiments with large doses have demonstrated that this agent de- presses the circulation. Observations on the intra-cranial circulation, as seen through the retina and drum membrane, have demonstrated that an artificial hyperemia results from the administration of medi- cinal doses. On the other hand, as Favier was the first to observe, quinine in large doses depresses the heart, arrests it in the diastole without impairing its contractility, and lowers the arterial tension (Chirone, Briquet). Quinine acts on the cardiac motor ganglia, and hence occur the feebleness of the heart's movements and in part the gen- eral lowering of the vascular tension (Lewizky). Besides these effects, it unquestionably depresses the vaso-motor system, after a short pre- liminary stimulation, probably (Jerusalimsky, Lewizky, Briquet). This depression of the heart from large doses occurs after the vagi are divided (Briquet, Schlockow, Kohler, Lewizky), and is more conspicu- ous when the agent is introduced into the jugular vein, indicating that the impression made on the heart is not through an increase of inhibi- tion, but on the cardiac ganglia. Immersion of the heart in a quinine solution quickly arrests its movements. In the normal condition of the human subject, quinine does not appreciably affect the temperature. In the course of some carefully conducted experiments a few years ago, I found that the maximum doses caused not more than a half-degree decline in a healthy adult. In fever, however, the influence of antipyretic doses is prompt and decided. This result may be attributed to several factors : to the de- pression of the heart and arterial tension, to the suspension of the oxidizing power of the blood, and to the inhibition of the white cor- puscles. Jiirgensen was the first to observe that quinine prevented the rise of temperature produced by certain physiological acts, as, for example, active exercise, but Kerner has more particularly developed the experimental evidence proving this fact. By active gymnastics, the temperature was found to be elevated two to three degrees Centi- grade ; but the previous exhibition of a full dose of quinine prevented this rise of the body-heat. Kerner also ascertained that the increased cutaneous secretion, the result of active exercise, was prevented by the administration of sufficient quinine. From all of these facts, it seems evident that the lowering of the temperature by this agent de- pends on diminished production of heat rather than increased radia- tion and loss by cooling of the skin. This statement seems confirmed by the experiment of Lewizky, made in Hering's laboratory, by wrap- ping a rabbit in protective envelopes to prevent loss of heat by cool- ing, and then practicing the intra-venous injection of quinine ; the re- CINCHONA. 173 suit was a depression of temperature as in animals not so enveloped. To such experiments, the author opposes the insuperable objection that the temperature in rabbits kept at rest declines, and to a remark- able extent, without the administration of any medicament. Never- theless, the fact of the reduction of temperature by quinine is un- doubted. By Popow, who admits the diminution of temperature, the influence of quinine over the body-heat is referred to some unknown biological process. In small doses quinine exerts a distinct stimulant effect on the cerebrum, increases the mental activity, and even exhilarates in some mobile constitutions. As some hyperemia is caused by it, the result- ing cerebral stimulation is probably secondary to this change in the vascular condition. In full medicinal doses, as the quinine accumu- lates in the brain, a sense of fullness in the head, constriction of the forehead, tinnitus aurium, more or less giddiness, even decided ver- tigo, may be produced. Dullness of hearing results from considerable doses, and deafness has in rare cases been permanent. In a long ex- perience of its use and extended observation, no case has come under my notice of permanently impaired hearing, although the temporary condition is usual. According to Knapp, Moos, and others, amaurosis is produced by very large doses. White atrophy of the optic disks occurs, and most of the vessels disappear from the field. This must be due to strong contraction of the vessels, since this condition is quite curable, the ordinary appearance of the retina being restored in most of the cases. Permanent atrophy of the optic nerve is, however, an occasional result. Amblyopia is frequently produced by the use of considerable doses kept up for some time. It is recovered from readily by suspending the administration of the remedy and taking the neces- sary steps to improve the intraocular circulation. In actually toxic doses all of the above symptoms have been intensified. There are in- tense headache with constriction of the forehead, dimness of vision or complete blindness, deafness, delirium or coma, dilated pupils, weak, fluttering pulse, irregular and shallow respiration, convulsions, and finally collapse and death. It is excessively rare to encounter such severe cerebral symptoms. The influence of quinine over the functions of the spinal cord is yet subjudice. Chaperon some time ago demonstrated that quinine lessened and ultimately abolished the reflex function of the spinal cord. This result he decided was due not to immediate action on the spinal cord, but to stimulation of Setschenow's center of inhibition of reflex movements. Brunton, who has repeated Chaperon's experi- ments, has found them to be correct. The observation of Schlockow, that the first effect of quinine is to increase the sensibility of the re- flex function of the spinal cord, has much probability in its favor. Heubach has also, after moderate doses, observed some evidences of 174 KESTOKATIYE AGENTS. the existence of reflex irritability, but the experiments of Brunton show that these reflex effects decline with the increasing stimulation of the inhibiting center. Brunton's experiments were also directed to ascertain whether the sulphuric acid in combination with the qui- nine was responsible for the effects observed, but the result proved that quinine is the active agent in stimulating Setschenow's inhibiting center. As quinine depresses the functions of the sympathetic system, its action is opposed to that of agents which have the power to promote uterine contractions, hence, a priori, it would not seem to be aborti- facient. Very numerous and conflicting statements have been put forth, because there are no exact data. The few cases in which uter- ine action followed the administration of quinine were, doubtless, due to malarial intoxication or to other causes, and hence the association of uterine action with the effects of quinine was accidental. The in- numerable instances in which quinine has been given during the exist- ence of pregnancy, without initiating contractions of the womb, are certainly conclusive against the view of its abortifacient power. While it is not a special uterine stimulant, it may exert such an ac- tion indirectly. When uterine inertia is due to depression of the vital forces, quinine, in moderate doses, then becomes a valuable stimulant, and is utilized for this purpose in obstetric practice. The diffusibility of quinine and its rate and mode of elimination have been studied by Bence Jones, Ciotti and Albertoni, and Kerner. Jones in his researches availed himself of the fluorescent property of animal tissues, possessed also in a high degree by the alkaloids of cin- chona, especially quinine. To this substance, as it appears in animal tissues, Jones gave the name " animal chinoidin," but he was not aware that fluorescence is a property possessed by large numbers of animal and vegetable bodies. Nevertheless, he recognized the fact that the diffusibility of quinine could be estimated by the increase in the fluo- rescence of animal textures, and he thus ascertained that in a half- hour after the administration of quinine a positive gain in fluorescence of the crystalline lens is observed. It is probable that under some circumstances — a catarrhal state of the mucous membrane, for exam- ple — a portion of the quinine taken fails to be absorbed, and is conse- quently excreted by the intestines (Byasson). The effect of this agent on the secondary assimilation is involved in more or less doubt. Opposing opinions have arisen from the different points of view taken. In the normal condition quinine, in small quantity, stimulates the nu- trition, and increases the excretion of waste products — urea, uric acid, creatinin, extractives, etc. ; but, in considerable doses, the opposite condition obtains — the decrease in the quantity of uric acid is espe- cially well marked (Ranke, Kerner) — and when administered in mala- rial fevers all the products of waste are greatly increased. The con- CINCHONA. 175 ditions attending the use of the remedy, therefore, influence the re- sult. Considerable doses in the normal state diminish the excretion of urea, uric acid, creatinin, and phosphoric and sulphuric acids (Kerner). Strassburg, however, failed to find any change in the car- bonic acid. According to the observations of Cutler and Bradford, quinine has an obvious effect on the globular richness of the blood, increasing the relative proportion of the white, and diminishing the red globules. The action of quinine on the spleen is still sub judice. Piorry was the first to note a reduction in the size of the organ pro- duced by quinine, but he had an exaggerated notion of the nicety by which a difference in the size of an organ could be made out by the ples- simeter and hammer. Kuchenmeister examined the subject experi- mentally in 1851, with negative results, but afterward, operating with larger doses, obtained confirmation of Piorry's view. Mosler, after dividing all the nerves of the spleen, ascertained that quinine in large doses still acted on the contractile elements, and reduced the size of the organ. Jerusalimsky, in an elaborate research, has established the same fact. That the enlarged spleen of malarial infection is re- duced by quinine is an undoubted clinical fact. From these positive observations it must be concluded that quinine does act on the spleen, notwithstanding there are numerous negative statements. It follows, hence, that the diminution in the red and increase of the white cor- puscles may be due to this action. Quinine diffuses out of the blood into the urine, chiefly, but also into the sweat, saliva, milk, and pathological exudations '(Kerner, Briquet, Binz). Jtirgensen found quinine in the urine in ten minutes after the hypodermatic injection. Thau had evidence of its presence in the urine in a half-hour after the ingestion of a half -drachm dose each by two persons, and he holds that the maximum elimination takes place in about eight hours, but the excretion is not completed until two days after the administration. According to De Renzi, quinine remains in the organism a variable number of days, and may indeed be discovered in the urine on the third day ; in a special case, as late as seven days. Binz also finds that the elimination of quinine is vari- able and rather slow, the maximum being excreted within forty-eight hours. From the time the agent appears in the urine, the systemic action is manifest, and the maximum effect of any given dose must be experienced in advance of the period of maximum elimination, which Thau places at eight hours. According to Kerner, quinine ap- pears in the urine in a somewhat modified form. The action of quinine has occasionally been attended by the ap- pearance of an eruption on the skin. Sometimes the exanthem has been in the form of an erythema, sometimes it has assumed the ap- pearance of urticaria ; again, it has seemed to be herpetic. There is, in fact, no constant and invariable eruption, and many of the reported 176 RESTORATIVE AGENTS. cases are open to the suspicion that the appearances on the skin are merely accidental, and not causative. Therapy. — A solution of quinine will sometimes, when applied to the nares, arrest an attack of summer catarrh, a malady which appears to be produced by the pollen of plants. The preparation most suitable for this purpose is an aqueous solution of the hydrochlorate (gr. iv — gr. viij — § j). This should be applied by a large camel's-hair brush, or spray-producer, to the nares and fauces. The utility of quinine in this peculiar disease will be determined by the extent to which the local trouble has proceeded ; it can be useful only when the irritation is confined to the nares and fauces. The aphthous ulceration (muguet) which succeeds to an exhausting entero-colitis, or which occurs in cachectic infants, is much improved by quinine — a grain or two every three hours. An attack of acute tonsillitis may sometimes be aborted by a full dose of quinine (ten to fifteen grains). This practice is especially indicated in those cases which proceed to suppuration, but the quinine must be administered before pus forms. The preparations of cinchona are much used as stomachic tonics. In atonic dyspepsia they are employed, like the simple bitters, to pro- mote the flow of gastric juice. In gastric catarrh they relieve that morbid state of the mucous membrane on which the increased produc- tion of mucus depends. For these purposes they may be combined with the mineral acids. The best preparation is the infusion ; the de- coction, although official, is inelegant and faulty. The alkaloid quinine is frequently used for the same purposes, and notably in the gastric catarrh of drunkards, combined with acids. When vomiting of yeast- like material is due to the presence of sarcina, quinine may be used in virtue of its power as a poison to these minute organisms, and as an anti-ferment. In these stomach-disorders other and less expensive drugs may be used with equal advantage. (See Hydrastis.) When there is a relaxed state of the gastro-intestinal mucous membrane, manifested by catarrh, diarrhoea, etc., but without inflammation, the preparations of red bark are more particularly indicated in virtue of the tannins which they contain. The reader need hardly be reminded that the preparations of cinchona are contraindicated in all inflam- matory states of the intestinal mucous membrane. Furthermore, if too long continued, they will set up an irritation, and perpetuate the troubles which they were prescribed to remove. Sometimes it happens that the entero-colitis of children (cholera infantum), which resists every possible combination of astringent and laxative, will yield readily to quinine. The author has seen quinine give prompt relief in the following : A child suffers with tenesmus, and after much straining voids a transparent mucus streaked with blood, but there is no fever nor other disturbance of the bowels, and the stools when passed are natural. CINCHONA. 177 The preparations of cinchona and quinine are very serviceable in that state of the mucous membrane which favors the development of ascarides. After the expulsion of the parasites, these remedies remove the saburral state of the mucous membrane. A combination of purga- tives and bitters will correct the following condition of things as they occur in children : A foul breath, coated tongue, capricious appetite, tumid belly, and constipation alternating with diarrhoea. The use of quinine as a restorative tonic in cases of debility is al- most universal. Given in moderate doses — six to twelve grains a day — it promotes constructive metamorphosis. Its utility is due not to any direct action on the blood, but to its stimulant effect on the digestive function, and the retardation of the combustion process. When cinchona or quinine proves irritant to the intestinal mucous membrane, this beneficial restorative action ceases. Iron and arsenic increase the power of quinine to promote construction of tissue and to retard waste. There can be no doubt in regard to the power of quinine to arrest the inflammatory process in its formative stages. Its utility, given with this view, ceases when the migration of the white corpuscles and the proliferation of the cellular elements of the inflamed parts have taken place, for it possesses no power to cause disintegration and ab- sorption of inflammation products. Administered at the critical mo- ment, a commencing fibrinous pneumonia, a pleuritis, an endocarditis, may be suppressed by a full dose (twenty to forty grains). Its power in this respect is much increased by combination with morphine. If the time have passed for the use of quinine in this way, it is employed with advantage as a restorative tonic in the various inflammatory affec- tions of low type, small doses (two to four grains) being given fre- quently. In septic diseases quinine has very important uses. Although the observations of Binz, showing the influence of quinine over septic pro- cesses, may not be applicable to the full extent for which, he proposes them, there can be no doubt of the good effects in practice of quinine in septicemia, pyemia, erysipelas, and puerperal fever. In these dis- eases, only large doses — five to twenty grains — every four hours, are useful. The author's experience in the treatment of acute rheumatism does not justify the use of large doses of quinine, as now employed by Bri- quet and his followers in France. In the hyperpyrexia of acute rheu- matism, it is true, large doses of quinine will depress the temperature, but we have less distressing and more effective means for accomplish- ing this object in the wet-pack and the cold bath. When the acuter symptoms have subsided, and the skin is cool and perspiring, and the pulse weak, quinine in moderate doses — two to five grains — is very ser- viceable. 12 178 RESTORATIVE AGENTS. A careful examination of the large number of facts which have now been accumulated, and considerable personal experience and ob- servation, have satisfied the writer of the inutility of quinine as a means of aborting or shortening the duration of typhus and typhoid fevers. Not only has this remedy little or no influence over the course and duration of these affections, but its irritant effects upon the gastro-intestinal mucous membrane, and its inhibitive influence, exerted through the organic nervous system, upon the heart and lungs, may, in some cases, render it positively injurious in large doses. As a rule, the dryness of the tongue, the diarrhoea, the subsultus, and the delirium of typhoid fever, are increased by it. In certain parts of the United States, the prevalence of a mixed type — typho-malarial — re- quires, under certain conditions, the use of quinine in continued fevers. But it becomes less and less effective as the typh-element predominates. When there are evidently true remissions — and not merely the rhyth- mical morning remission and evening exacerbation characteristic of typhoid — quinine is indicated, and it is most effective when adminis- tered in an occasional large dose during the remission. When there is a condition of hyperpyrexia, or of continuously elevated tempera- ture, which endangers life by parenchymatous degeneration and car- diac or cerebral paralysis, quinine in antipyretic doses renders an incontestable service. This opinion of the author is fully confirmed by the committee of the Clinical Society of London, who find that large doses of quinine have a marked effect in reducing the temperature in pyrexia, and that, although, with the exception, perhaps, of certain cases of rheumatic fever in which the temperature is high, no decided evidence has been obtained to show that quinine has any influence in shortening the attack of a specific disease such as typhus or scarlet fever, yet from the marked effect on the temperature and pulse there is reason to believe that at the critical stage of acute disease, when pulse and temperature are high, a large dose of quinine may be em- ployed with benefit. Jiirgensen, Ringer, Liebermeister, and other authorities, and a vast clinical experience in all civilized countries, are now agreed in respect to the fever-reducing power of quinine and to the absence of ill results from large doses (especially Liebermeister). Liebermeister, indeed, says, if he were restricted in his choice to one antipyretic, he would select quinine. The quantity necessary to effect a decided reduction of the body-heat in fevers is determined by the age, the amount of disturbance, and the individual susceptibility to its action. In general, it may be stated that from twenty to sixty grains will be required. The antipyretic effect is more decided if it is given toward the close of the exacerbation or during the remission in typhoid or other fevers. The duration of the effect is " from one to forty-eight hours " ; consequently, a repetition of the dose will be necessary, if it is desired to maintain the reduction of the temperature. CINCHONA. 179 A few large doses at short intervals until the necessary quantity is reached, or a single maximum dose if the stomach is tolerant, should be prescribed, rather than a succession of smaller doses. The rapidity with which elimination takes place is a sufficient reason for adopting the former mode of administration. The effect of quinine is not less happy in the fevers of childhood, and comparatively large doses are well borne at this period, as Jacobi, especially, has shown us. The same rule should be followed as in the case of adults : to give the amount required in several doses within a brief period — an hour, ac- cording to Liebermeister — or at one time. The antipyretic use of quinine should not be confounded with its tonic or supporting quali- ties. In the treatment of fevers, the typhoid state, or the condition of adynamia supervening during the course of fever, small doses (two, three, or four grains), at short intervals, are employed for the stimu- lating effects which they have on the organs of circulation, respira- tion, and digestion. Large doses, as has been set forth, depress these functions. In cerebrospinal meningitis, doubtless a continued fever with cere- brospinal lesions, quinine is indicated under the conditions already de- fined for the treatment of other inflammations, viz., in the beginning of the disease, when the alterations of cutaneous sensibility first occur, and before the febrile movement has developed. If a few large doses — twenty to thirty grains — do not produce a good result, it is useless to repeat them, or to pursue a tentative plan with small doses. In the treatment of the eruptive fevers, variola, scarlatina, rubeola, quinine has an important place. It is used in small doses, frequently repeated in adynamic states, and in large doses at longer intervals to reduce hyperpyrexia. In scarlet fever, Dr. Hood especially urges the use systematically of quinine from the earliest stage of the disease, preceded by an emetic and purgative, and he states as the result of this practice that since he has adopted it he has not lost a single case of this disease treated by him from the beginning. In measles, large doses of quinine have an unquestionable utility in relieving the catarrhal pneumonia, and in preventing those changes in the exudation products which end in caseation. The most important uses of quinine are those which, in the present state of our knowledge, can not be deduced from a study of its physi- ological actions, viz., the cure of malarial diseases. It is true, the toxic action of quinine on minute organisms is supposed by Binz and his followers to be the true explanation of its methodus medendi, but the exact influence of these organisms in the causation of malarial diseases has not hitherto been defined. The recent discovery of the bacillus malarim by Klebs and Tommasi-Crudeli, if confirmed, will afford the needed explanation. The power of quinine to render in- active the minute organisms of disease must also be exerted against 180 RESTORATIVE AGENTS. the malaria-germ. Other agents possess this power, it is true, but they are, unlike quinine, destructive of the tissues as well as of the disease-germs. The alkaloids of cinchona are employed as prophylactics against malarial infection. The experience of the English naval service, of crews engaged on the coast of Africa in the suppression of the slave- trade, of the expeditionary force into Ashantee under Lord Napier, and of our late civil war, has abundantly shown that quinine is in a high degree prophylactic. The first public reference to this property seems to be that of Dr. Bryon in 1854, who called attention to the success which attended its use among the crews of the British vessels serving on the coast of Africa. Since that time, for several years the statistical reports of the British naval medical service have contained conclusive evidence on this point. Dr. Joseph Jones has published since the close of the civil war some valuable statistical data, showing the efficiency of quinine as a prophylactic. The troops who were the subjects of ex- periment were stationed in a highly malarious locality. Of the num- ber, 230, who took no quinine, 134 had fever. Of those who took qui- nine irregularly, 246 in number, 96 had fever. Of the 506 who took quinine regularly, 98 had fever. The proportion of cases of fever was, therefore, 1 to 5*66 men. On the coast of Africa, the proportion has varied from 1 in 8 to 1 in 20. Of the unprotected, more than one half — on the coast of Africa, three fourths — were attacked by malarial disease in some form. As the quantity of quinine daily taken has been usually three to five grains, it is probable that the results would be even more favorable if a larger quantity of the prophylactic were given. When the poison is not intense, this amount may be sufficient, but if concentrated and active, and the conditions are otherwise un- favorable, twice as much should be administered daily. An enor- mous experience has now shown that quinine is entirely free from in- jurious effects when taken as a prophylactic. It is probable that the influence slowly decreases, and that some addition to the daily quantity may be necessary after a time. The prophylactic dose should be ad- ministered on rising in the morning, and may be usefully prescribed in a cup of black coffee, or in pill-form. The practice adopted in the civil war, of giving whisky as the vehicle, is not to be commended. If the quinine administered fail to prevent the disease, those attacked will suffer far less severely than the unprotected. Experience has shown that, to be entirely efficient, the quinine must be administered for some time, at least ten days, after exposure to the causes of fever (Jones). The mode of using quinine for the cure of intermittents may be formulated as follows : The antipyretic is nearly equally effective whether administered in the interval or during the seizure. CINCHONA. 181 If time is an element of importance, no delay is necessary in order to give the remedy in the stage of apyrexia. To save the suffering and exhaustion of the febrile movement, the attack should be anticipated, and, if possible, prevented. As the maximum effect of the quinine is attained in about five hours after being taken, it should be administered this period of time, at least, before the expected paroxysm. As the elimination of quinine takes place with considerable rapid- ity, the maximum curative effect is obtained by the administration of the whole amount required in a single dose, rather than by a succes- sion of small doses (Prize Essay). An intermittent may be successfully treated by giving, during the interval, a number of small doses frequently repeated. The author is convinced by extended observation that a full dose of quinine (ten grains) in the sweating stage, and the same quantity five hours before the time of the next paroxysm, is the more effective method. The anti-periodic property of quinine is increased, and the cerebral effects of large doses diminished, by combination with morphine. It is well known that intermittents, arrested by quinine or other anti-periodics, manifest a tendency to recur about the septenary periods ; therefore, ten to fifteen grains of quinine should be administered in anticipation of these recurrent paroxysms, until the third septenary period has passed. Meanwhile, the organs damaged by the malarial infection — intestinal canal, liver, spleen, kidneys, etc. — require appropriate treatment. The action of quinine is much assisted by the continuous administration of arsenic during the intermissions, and until the third septenary period has passed. The unpleasant cerebral effects of quinine are lessened or prevented by the simultaneous administration of diluted hydrobromic acid : I£ Quininse sulph., 3 j ; acid, hydrobromic. dil., 3 ij ; aquae, 3 xiv. M. Sig. : One or two teaspoonf uls at a dose. In the treatment of remittent fever two modes of using quinine are employed : first, by emetics, purgatives, baths, diaphoretics, etc., to secure a distinct remission when the remedy is administered ; second, to give it in sufficient dose immediately, relying on its apyretic effect. The author is convinced that the latter plan is preferable: from twenty to thirty grains in a single dose once or twice each day until the tem- perature is reduced to normal. This use of the remedy need not inter- fere with other appropriate medication. In the so-called pernicious fever, it is agreed on all hands that the safety of the patient is secured only by the prompt use of large doses (twenty to sixty grains), and administration by the stomach, rectum, and skin may be in turn or simultaneously resorted to. In chronic malarial infection, important changes have been pro- duced in the intestinal canal, liver, spleen, kidneys, cerebro-spinal axis; the paroxysms of fever occur irregularly ; various abnormal manifes- 182 RESTORATIVE AGENTS. tations of the infection take place (dumb ague, enlarged spleen, etc.). Under these circumstances, quinine is less curative than when the infec- tion is recent, and the paroxysms will recur from time to time notwith- standing its use, unless these structural alterations are corrected. In chronic malarial disease, salicylate of quinine and salicylate of cincho- nidine are especially effective, fy Cinchonidinae salicylat., 3 ij ; acidi arseniosi, gr. j ; ferri sulph. exsic, 3 j. M.

In periodical affections of malarial origin, quinine is equally as ef- fective as in the periodical febrile diseases, but somewhat larger doses are necessary. A difficulty of diagnosis often arises in these diseases, for the reason that the neuroses are irregularly periodical in their manifestations, when not malarial in origin. The existence of a ma- larial cachexia, and the more uniform periodicity in the recurrence of the paroxysms, will enable the practitioner to distinguish the neuroses of malarial origin from the other functional disorders of the nervous system. The following group contains the disorders of the sensory nervous system caused by malaria : tic-douloureux, cephalalgia, cer- vico-brachial neuralgia, cervico-occipital neuralgia, dorso-intercostal neuralgia, lumbo-abdominal neuralgia, mammary neuralgia, crural neu- ralgia, gastralgia, enteralgia, hepatalgia, nephralgia, hysteralgia, ova- ralgia, sciatica, angina pectoris. The following motor disorders, also, are produced by malarial influences : epilepsy, chorea, stricture of urethra, hiccough, laryngismus stridulus, asthma, summer catarrh. These neuroses may occur as an expression of malarial infection, being substituted for the ordinary chill, fever, and sweat, or they may assume the orderly periodical character in consequence of having occurred in an organism already under the influence of the malarial cachexia. If they are of malarial origin, the specific action of quinine will speedily prevail against them. These malarial neuroses require large doses of quinine, and the same fact is true of all irregular mani- festations of malarial infection. Ten to twenty grains, according to the severity of the attacks and the obstinacy with which they recur, are necessary, and the paroxysms should be anticipated by the exhi- bition of the remedy from three to five hours before the expected time. In cases of malarial neuralgia, the curative effect of quinine is enhanced by combination with morphine, either in the same prescription or by simultaneous administration of the latter subcutaneously. Diarrhoea, dysentery, jaundice, and hypertrophy of the spleen oc- casionally occur in the periodical form, or are due to the immediate influence of paludal miasm. Under these circumstances quinine af- CINCHONA. 183 fords relief without the use of any other remedy. Very frequently the diarrhoea, dysentery, and jaundice are results of structural alterations in the liver and the glandular apparatus of the intestine, and are not merely functional disorders which quinine may remove. In malarial enlargement of the spleen, quinine is supposed to be especially effec- tive ; but quinine exhibits a curative power only in cases of simple enlargement, and does not affect that condition known as " fleshy spleen," or chronic splenitis, of inflammatory origin. Hematuria, when distinctly intermittent and arising from malarial infection, is cured by quinine, but large doses are necessary. Accord- ing to Karamitsas, sometimes hematuria is caused by this agent. Cases of cerebral disease, occurring in weak and anaemic subjects, are sometimes much improved by small doses of quinine. The author has observed great relief by the use of this remedy in the following group of symptoms, occurring in men advanced in life : Headache, vertigo, failure of memory, and despondency, associated with a slow pulse, an atheromatous degeneration of the vessels, puffiness of the eyelids, and dilatation of the superficial veins of the head. From three to ten grains daily may be given with advantage, the effect being to remove that sluggishness of the intra-cranial circulation on which these symptoms depend. In insanity, especially the puerperal form, when there is much weakness, and the skin is cold and sweating, qui- nine is very useful. When there is a condition of adynamia — the usual state — in delirium tremens, small doses of quinine assist materially in tranquillizing the patient. In that preliminary stage known as " hor- rors," characterized by restlessness, tremor, nausea, and anorexia, qui- nine, with a mineral acid, renders important service by restoring the digestive function, and by giving steadiness to the cerebral motor centers. Although headache (hemicrania) and neuralgia of malarial origin are cured by quinine, by no means equally successful results follow the use of this remedy in ordinary headache and neuralgia. Quinine is largely employed, it is true, in these affections when not caused by malaria, but it is useful only when anaBmia is present and is causative. The same remark is true of epilepsy and chorea. An attack of acute catarrh may often be entirely aborted by a full dose (ten grains) of quinine and morphine (one half a grain), if given at the incipiency of the attack. After the acute symptoms have subsided, quinine is very serviceable in hay-asthma. Diphtheria being an adynamic disease, quinine is used by the stomach with a view to its restorative action, and in the form of spray to arrest the spread of the exudation in the fauces. The power of quinine to kill bacteria and micrococci renders its local use a rational measure in a disease characterized by an enormous multiplication and diffusion of micro- cocci. 184 RESTORATIVE AGENTS. Laryngismus stridulus, a reflex spasm of the muscles of the larynx occurring in rickety, ill-fed, and anaemic children, may be prevented recurring by the use of quinine in the intervals between the attacks. Quinine is one of the remedies which is used in membranous croup, but the reported successes were probably cases of spasmodic croup. There can be no doubt regarding the good effects of quinine in asth- ma, after the severity of the paroxysms has somewhat abated, as an apyretic in the fever which succeeds, and as a restorative tonic. It is also the most useful tonic which can be employed in chronic bron- chitis, with profuse expectoration (bronchiectasis). The hectic fever and sweats of phthisis are prevented by large doses (fifteen to twenty grains) of quinine, but this remedy really has no influence over the course and progress of the disease. In shin-diseases, when there is present a lowered condition of the vital forces, quinine is indicated. It is the most valuable remedy in erysipelas and erythema nodosum. It is a curious fact that in many subjects a full dose of quinine will cause an erythema, with dilated pupils, phenomena closely analogous to those produced by belladonna. Ecthyma and impetigo, usually arising in a feeble state of the assimi- lative functions, are cured by quinine. Quinine is largely employed in surgical affections, to sustain the powers of life during protracted suppuration, and to check the forma- tion of pus. It is the most generally prescribed remedy for surgical fever. A full dose of quinine, given before the operation, may pre- vent the chill and fever which succeed in some subjects to the opera- tion of catheterization. Subcutaneous and Local Uses of Quinine. — The increasing use of quinine hypodermatically requires further consideration of this sub- ject. In pernicious intermittens and remittents, when life is put in imminent danger, the most speedy and effectual way of introducing the remedy must be employed. Besides the hazards due to the inten- sity of the poison, an irritable stomach and rectum prevent the intro- duction of the remedy by either of those channels. The subcutaneous method then becomes most important. Again, in obstinate and re- peatedly relapsing intermittents, the introduction of the remedy by the skin imparts to it greater curative power. In enlarged spleen (ague-cake), malarial jaundice, with great irritability of the stomach, and a catarrhal state of the gastro-intestinal mucous membrane, the subcutaneous method becomes necessary, or, if not essential, is much more effective. Quinine and the sulphate simply suspended are not adapted to subcutaneous use. Several cases of tetanus have been reported from New Orleans (Sale), and two cases occurred in one regiment of the British Indian Army from their use in this way. The salt employed for hypodermatic use should be sufficiently solu- ble that no undissolved particles be thrown under the skin. Various CINCHONA. 185 solutions have been proposed. The muriate is more soluble than the sulphate — dissolves in twenty-four parts of cold water, and about three parts of alcohol. One grain will dissolve in about fifteen min- ims of hot water, and in a much less quantity of alcohol-and-water, but alcohol is irritating. Lente's solution, which is much employed in New York, is prepared as follows : I£ Quininae disulph., grs. 1 ; acid, sulphuric, dil., in, c ; aquas font., | j ; acid, carbolic, liq., tti v. Solve. This contains six grains to the drachm. Dr. Lente directs that the quinine and water be heated to the boiling-point when the acid is added. The solution is then filtered into a bottle and the carbolic acid added. Below 50° Fahr. it must be warmed before using. A solution of kinate of quinine is much used at Guy's Hospital at the strength of one to four. The kinate is obtained by decomposing sulphate of quinine with the kinate of barium. The mode of preparing the solu- tion is as follows : Put into a beaker 3 vj of distilled water and 3 ij of kinate of quinine, and heat until the salt dissolves, which it does al- most immediately, and then add enough distilled water to make up to 5 j. The disadvantage of so concentrated a solution is the incrusta- tion, by evaporation, of the bottle and syringe with the solid kinate. The sulpho-vinate of quinine is very soluble — one part in three of water at 60° Fahr. — and is readily prepared by double decomposition between the alcoholic solutions of sulpho-vinate of sodium and sul- phate of quinine. Gubler advocates the hydrobromate, as follows : I£ Quininaa hydrobromat., grs. xlviij ; aquae destil., 3 iv. M. Dis- solve by heat if necessary. Five minims contain one grain. Recently a new compound salt of urea and quinine has been pro- posed, and it seems to possess distinct advantages over every other preparation : it is designated quinia bimuriatica carbamidata, and is formed by Drygin from a combination of twenty parts of muriate of quinine, twelve parts of muriatic acid, and three parts of urea. The resulting salt is soluble in equal parts of water. The utility of this compound is not entirely theoretical. Practical trials made at Ham- burg have demonstrated its fitness for hypodermatic use. A fifty-per- cent solution has usually been employed, and a half to three syringefuls (ill xv to 3 jss) injected. The local irritation is represented as slight. Very favorable reports have been published in respect to the utility of the hydrobromate brought forward by Gubler. In the hands of Ray- mond, Soulez, and others, intermittents are said to have ceased after two injections of three grains each of this salt. The usual method pursued was to inject one and a half grain of the hydrobromate twice morning and evening, and, although six to twelve grains were usually successful, in one case thirty grains were required. It has also been employed in the treatment of acute rheumatism. Quinine in solution is applied in various affections of the fauces by atomization. In diphtheria especially have good results been produced. 186 RESTORATIVE AGENTS. A saturated solution of the muriate or of the bromide may be thus employed. There can be no doubt that a solution of quinine applied to the nares may be very beneficial at the onset of hay-asthma, as first shown by Helmholtz. The author has seen several cases benefited greatly ; but to achieve success the applications must be thorough and timely. The secret of any good effects it has, is afforded by its toxic action on germs, and possibly on the pollen of certain grasses, to the presence of which the irritation of the air-passages is ascribed. As soon as the first symptoms are experienced, the mucous membrane should be cleared of mucus by means of a nasal syringe, throwing a solution of common salt, muriate of ammonia, or chlorate of potassa, and then the quinine solution should be applied by a camel's-hair brush to the anterior nares, or by the post-nasal syringe to the whole canal.

Antagonists and Incompatibles. — The alkalies and their carbon- ates are incompatible with the acids and with metallic salts. The caustic alkalies decompose the alkaloids of belladonna, stramonium, hyoscyamus, duboisia, etc. In case of poisoning, the antidotes to be employed are — acetic, citric, or tartaric acids, in the form of vinegar, cider, lemon- juice, etc. Demulcents and the fixed oils limit the cor- rosive action of the caustic alkalies, and should therefore be given freely. Synergists. — The alkalies assist each other's action. All agents promoting waste — for example, mercury, the iodides, etc. — increase the therapeutical activity of the alkalies. Physiological Actions of the Potash Salts. — The most recent experiments having shown that potash has quite distinct properties from the other alkalies of the group, each member of the group is con- sidered separately. As an alkali, potash combines with acids to form salts, and with fats to form soaps. As it has a great affinity for moist- ALKALIES. 189 lire, and dissolves albumen, and is a very diffusible substance, it exerts a destructive action on the animal tissues. These chemical facts ex- plain the active caustic properties of potassa f usa. In the stomach the salts of potash obey chemical laws, neutralize the free acid, and sapon- ify oily or fatty matters. Given when the stomach is empty, potash, as do the alkalies in general, promotes the acidity of the gastric juice, by increasing the diffusion of those constituents of the blood from which the acid of the stomach is elaborated ; but, as a large amount of alkali will neutralize a corresponding proportion of acid, it is obvi- ous that, to obtain an increased quantity of acid gastric juice, the amount of alkali administered must be small and rightly timed. When a toxic dose of potassa, of the carbonate, nitrate, or chlorate, is taken, violent local inflammation results. The action and the ap- pearances are somewhat different as regards potassa and its salts. The former liquefies the tissues, and extends its escharotic action widely and deeply, the sloughs being surrounded by a zone of inflam- mation. The salts, according to their activity and the quantity taken, set up a high degree of inflammation, cause intense burning pain about the epigastrium, nausea, vomiting, sometimes of bloody mucus, purg- ing, the stools being watery and profuse, or they may be dysenteric. In the case of caustic potash, marks of corrosive action, sloughs of the mucous membrane, bloody oozing, may be seen about the lips, mouth, and fauces, and shreds of bloody and sloughing tissues vomited. In case of toxic action of potassa and its salts, the local destruction, pain, and inflammation are accompanied by the usu^l systemic symptoms — great depression of the powers of life, a weak, rapid pulse, shrunken countenance, cold surface, followed by coma and insensibility. In a small proportion of cases the local mischief is not great, but the effects of the poison are expended on the nervous system, and assume the form of muscular weakness, paralysis of the inferior extremities, weak action of the heart, and coma, and a very large dose may cause death suddenly by paralysis of the heart before the local inflammation has time to develop. The nitrate and chlorate are the most active of the salts, but all potash bases have more or less power in the same direc- tion. The well-known case of Dr. Fountain, of Iowa, illustrates some points in the action of chlorate of potassa. Entertaining some theo- retical notion of the curative power of this remedy when administered in considerable doses, he took an ounce to demonstrate its innocuous- ness. Violent gastro-enteritis was produced ; at first there was free diuresis, but urinary suppression followed, and death ensued in seven days after the ingestion of the poison. When recovery takes place after poisoning by caustic potash, deformity of the mouth, stenoses of the oesophagus, cardia and pylorus, may remain, and then, after a par- tial improvement, the mechanical interference with the functions of these organs causes a more or less rapid marasmus. 190 AGENTS INCREASING WASTE. When the alkaline bicarbonates are taken on an empty stomach they diffuse quickly into the blood, where, meeting the neutral phos- phate of sodium, they are decomposed, acid phosphate of sodium being formed, and this compound, diffusing out of the blood into the urine, increases the acidity of that excretion (Rolfe). The result is different when bicarbonate of potassium is taken during digestion, for then, the reaction of the gastric juice being strongly acid, this salt is decomposed, carbonic acid is given off, and the alkaline base lessens the acidity of the stomach, increases the alkalinity of the blood, and diminishes the acidity of the urine. The salts of potash formed with vegetable acids undergo conversion into alkaline carbonates in their passage through the organism, and are eliminated in this form, thus causing an alkaline condition of the urine. The period of administration unquestionably influences the result to a large degree, as has just been stated. The increased alkalinity of the blood, produced by the administration of the potash salts, promotes its oxidizing function (Buchheim, Basham, Kohler, and others). The relative quantity of uric acid is diminished, and of urea increased. Basham, instructed by the observations of Schunck, that oxal urate of ammonia is a product of the oxidation of uric acid, and that the former is readily converted into urea and oxalic acid, holds that the same process takes place in the organism when uric acid is subjected to the action of the potash salts. The urine of patients suffering from uric-acid deposits was carefully examined after a course of the citrate or carbonate of potassium, and it was found, after an interval, of about three days, that the urea was in one case trebled in amount, and in others more than doubled, while the uric acid was reduced to a fractional part of what had existed (Basham). The facts, then, are conclusive in regard to the increase in the oxida- tion processes, caused by the administration of potash, and its salts formed by combination with carbonic and the vegetable acids. The changes in the fatty constituents of the blood consist, probably, in a process of saponification and excretion. Nitrate and chlorate of po- tassium produce very different effects on the blood. Not parting with their oxygen in the system, and excreted undecomposed, the effects noted in the blood must be due to their action as a whole. The changes made by the chlorate in the composition of the blood have been studied recently by Marchand, in cases of poisoning in man and by experiments on animals. The blood assumes a dark, brownish, or chocolate color, and can no longer take up oxygen ; the haemoglobin is decomposed, and the injured blood-corpuscles accumulate in the spleen ; the kidneys are brownish in color, and the tubules are choked with the broken-down materials of the red globules. The peculiar brownish color of the blood is found, by spectroscopic analysis, to be due to a substance identical with Hoppe-Seyler's methsemoglobin. These effects separate the chlorate, nitrate, and other compounds of ALKALIES. 191 potassa very distinctly from the compounds with vegetable acids, while the latter also differ distinctly from the former in the power to alkalinize the blood and urine. Avery considerable reduction of temperature is produced by large doses of the potash salts (Podcopaew, Guttmann, Traube). This effect, due especially to chlorate and nitrate of potassium, may be readily ex- plained by the changes in the haemoglobin, which impair its function as a carrier of oxygen. Ordinary doses do not affect temperature de- cidedly, probably because they do not have the power to change the properties of haemoglobin. The alterations produced in the composi- tion of the blood by the salts of potash necessarily affect the nutritive functions. The increased elimination of urea, the waste of the fatty constituents of the blood and of the tissues, the more rapid process of oxidation, results of the action of the potash salts, necessarily place these remedies among the list of those promoting destructive meta- morphosis. Drs. Ringer and Murrell find chloride of potassium to be a proto- plasmic poison, and to this effect they refer its action on the brain and nervous system and on the heart. That potash is a poison to the heart has long been known. The experiments of Podcopaew, repeated sub- sequently by Guttmann, confirm this. Whether introduced directly into the circulation, by injection into the jugular vein or subcutane- ously, the paralysis of the heart follows — more speedily, when the poison reaches the heart more directly. The arrest of the heart takes place in the diastole, and occurs after division of the pneumogastric, whence it must be concluded that the effect on the heart is not exerted through increase of the inhibition. As, when a large dose is suddenly precipitated on the heart, its movements are speedily arrested, and the muscle of the beart does not then respond to electrical excitation, the effects of the poison must be expended chiefly on the muscular tissue (Traube), but not wholly so, since, before the electro-contractility is entirely abolished, all motion may be arrested. The cardiac ganglia must therefore participate in the changes wrought by the poison. The effect of potash on the tension of the vessels — on the blood-pressure — is much influenced by the quantity and mode of administration. A large quantity by intra-venous injection quickly poisons the heart and lowers the pressure in the arterial system. On the other hand, small doses increase the tension (Hummel, Traube). As elimination takes place very rapidly, it is not surprising to find that the normal pressure is quickly restored. This difference in the result, due to the size of the dose, is largely responsible for the conflicting statements which have been put forward. It has been ascertained by Ringer and Murrell, and by Guttmann, that the contractility of the muscles and the irritability of the motor nerves persist after complete paralysis induced by the potash salts. 192 AGENTS INCREASING WASTE. The paralyzing action must, therefore, be exerted on the spinal cord. In fact, as Ringer and Murrell have shown; potash, being a protoplas- mic poison, affects most injuriously the most highly specialized struc- tures ; hence the brain and spinal cord suffer earlier and more severely than do other tissues. Valentin has made some very interesting com- parative observations on the effects of the chlorides of the alkalies, when frogs are immersed in solutions of these salts. In a ten-per-cent solution of chloride of ammonium, the frogs died in two or three min- utes ; in the chloride of potassium and lithium solution of the same strength, death occurred in ten minutes ; in chloride of sodium solu- tion, in ten to twenty-five minutes ; and in chlorides of calcium and barium solutions, also of the same strength, death ensued in the course of thirty minutes. Besides the cutaneous irritation, the effects were similar to those already mentioned, except the changes in nerve and muscle reactions, the result, doubtless, of imbibition. The early sus- pension of the reflexes, the fibrillary trembling of the muscles, and the loss of electro-contractility almost at once, indicate the local action of the poison. The elimination of the potash salts takes place by various channels, chiefly by the kidneys, but they also appear in the saliva, sweat, milk, and other secretions. The effect of these salts on the reaction of the urine and the differences in result due to the period of administration have been pointed out. The state of acidity of the stomach greatly affects the reactions of the urine produced by the carbonates of po- tassa (Ralfe). The salts of vegetable acids undergo decomposition in their passage through the system ; they render the urine alkaline, and greatly increase the excretion of free carbonic acid (Parkes). The after-condition of the urine is that of increased acidity (Ralfe). The nitrate and chlorate of potassa are eliminated unchanged, and do not affect the reaction of the urine (Laborde). The notion entertained in some quarters that chlorate of potassa parts with its oxygen, is en- tirely erroneous. These salts increase the amount of urinary water, and, in common with the other members of the family, promote oxi- dation and the excretion of urea. While the acetate increases the discharge of urinary water, it actually lessens the quantity of solids excreted (Parkes). The production of saliva is much increased by the chlorate, which is freely eliminated by the salivary glands (Laborde). It is a very important fact, which we owe to Dr. Jacobi, of New York, that chlorate of potassa irritates the kidneys, and if continued a suffi- cient time sets up a chronic nephritis. Others have made similar ob- servations, so that the popular use of this supposed harmless agent should be discouraged by the -medical profession. Therapy of the Potash Salts. — Chlorate of potash is in almost universal use as a remedy for catarrhal inflammation of the mouth and fauces, for acute tonsillitis, aphthous ulcerations of the mouth, ALKALIES. 193 stomatitis mate-ma, or nursing sore mouth, and mercurial stomatitis. As above stated, the domestic use of this remedy for sore mouth and sore throat has become an evil which should be discouraged. For or- dinary purposes this remedy should not be employed. The utility of the chlorate is, however, so decided in the case of stomatitis materna, that all other considerations are merely secondary. In this malady large doses (fifteen grains to 3 j three or four times a day) are neces- sary, and a less amount will fail to effect a cure. In mercurial stoma- titis, ulcerative tonsillitis, diphtheritic angina, etc., the following for- mula may be applied locally : I£ Potassii chlorat., 3 j ; acid, carbolic, 3 ss ; glycerini, § j ; aquae, § iij. M. Sig. : Lotion. The potash salts are used with great advantage in many stomach- disorders. It is an undoubted chemical fact that an excess of acid is relieved by an alkali, but the result is not permanent, and the cause of the acidity is not removed. Small doses of an alkali, given with a bitter before meals, promote the flow of gastric juice, and are a ser- viceable combination in atonic dyspepsia. ~fy Inf. calumbse, § iv ; liq. potassae, 3 ss. M. Sig. : A dessert to a tablespoonf ul three times a day before meals. Administered after meals, the alkalies will relieve the acidity due to an excessive production of acid, or to the acid fer- mentation of the starch, sugar, and fat, in the food. An acid given before meals is the proper remedy for the excessive formation of the acid of the gastric juice. Alkalies render an important service in case of indigestion of fats. Not only do they prevent the formation of butyric acid, but they assist in the process of emulsionizing the fats and help their absorption. In diseases of the liver, and when from any cause the flow of bile into the intestine is prevented, alkalies assist in the digestion and absorption of fats. The indigestion of obese sub- jects, and of the gouty and rheumatic, is usually cured or alleviated by alkalies. The lithia salts are generally to be preferred in gouty and rheumatic subjects ; but, generally speaking, the bicarbonate of potassium is the most useful of the alkali remedies in the above-men- tioned maladies. The salts of the alkalies, especially the citrates, tartrates, and car- bonates of potassium, are useful in inflammatory diseases to lessen heat, and to promote excretion of the products of inflammation. When oxidation is deficient, as represented in an excess of uric acid in the urine, a coated tongue, hebetude of mind — the so-called " bilious state " — relief is afforded by the use of the alkalies and their laxative salts. The alkaline treatment of acute rheumatism is based on these prin- ciples. Although this plan of treatment may not be adapted to all cases, there can be no doubt of its utility in respect to a considerable proportion. It must be borne in mind, as Dr. Fuller, the most influ- ential advocate of the method, informs us, that the alkaline treatment consists in a plan, made up in part of the use of bicarbonate of potas- 13 194 AGENTS INCREASING WASTE. sium, and in part of certain adjuvants, notably quinine. The main point in the treatment consists in the administration of remedies to induce an alkalinization of the system as quickly as possible, for when this is accomplished further joint and heart complications are not like- ly to occur. Fuller gives not less than an ounce and a half of bicarbon- ate of potassium, largely diluted with water, in the first twenty-four hours of the treatment. Sometimes this salt is given in effervescence with lemon-juice — in the proportion of two drachms to an ounce of lemon-juice — every three or four hours, or with citric-acid solution. If the bowels are torpid, one or more compound cathartic pills are pre- scribed in addition. As soon as the urine ceases to exhibit an acid reaction — usually at the expiration of twenty-four hours — the quantity of potassic carbonate is reduced one half. If the urine continues alka- line at the expiration of another period of twenty-four hours, the alkali is further reduced one half, and, on the fourth day, the same conditions continuing, the treatment ceases to be exclusively alkaline. Then the alkali is reduced to the amount necessary merely to keep the urine neutral — about a half -drachm of the bicarbonate three times a day, and quinine is given. In Dr. Fuller's words, three grains of quinine, dis- solved in lemon-juice, is given three times a day in effervescence with half a drachm of bicarbonate of potash. In ninety-four cases of acute rheumatism thus treated, the average duration, from the beginning of treatment, was eleven days. This method is adapted to the treat- ment of the plethoric, obese, and muscular subjects, and in the experi- ence of the author is not well suited to the pale, delicate, and anaemic rheumatic. In irritation of the urinary organs due to an excess of acid, the combinations of potash with the vegetable acids possess a high degree of utility. The liquor potassae is much prescribed under these circum- stances, but, as it is very irritating to the stomach, the salts are prefer- able, and they are equally effective. The liquor potassii citratis is an excellent form for this purpose. There is no doubt that the long-con- tinued use of alkalies (citrate, acetate, and carbonate of potassa) will effect the solution of renal calculi, which are usually composed of uric acid. As the urate of soda is often the nucleus of these formations, the soda alkalies should not be used. Small doses taken daily for length- ened periods are necessary. Such alkaline waters as the Vichy may be used if more agreeable to the patient, but the best results are ob- tained by the administration of the citrates and tartrates in a large quantity of distilled water. When the urine is acid in any of the forms of cystic irritation — from stone, cystitis, stricture, enlarged prostate, etc. — great relief is experienced from the use of alkalies, notably the liquor potassae, the citrates, acetates, and carbonates of potassium. When the urine is alkaline in reaction, no benefit can be derived from the use of .these remedies. ALKALIES. 195 The bitartrate and the acetate of potassium are very certain diu- retics, especially the first named. They are most effective when given largely diluted with water. A pleasant form in which to administer cream of tartar is the familiar " cream-of -tartar lemonade," made as follows : A sufficient quantity of the remedy is dissolved in hot water ; when cold the clear solution is poured off ; some lemons are cut up and put in it, and it is sweetened to the taste. This solution may be drunk ad libitum, Considerable stomach and intestinal distress often follows the free use of dilute solutions of these potash salts, in consequence of the abundant production of carbonic-acid gas. The potash salts are indicated as diuretics in desquamative nephritis, and in general dropsy from valvular disease of the heart. By determining a free urinary discharge in the one case, they assist in washing out the obstructing epithelium in the tubules ; in the other, they relieve the tension of the venous system. Very little is accomplished by the use of alkaline diuretics in dropsical accumulations in the various cavities. Sodium. — Soda. — Soda ; Natrium, Ger. ; sonde, Fr. Occurs in ir- regular flat masses.

Physiological Actions of the Salts of Sodium. — In respect to the merely alkaline properties, there is a close correspondence be- tween potassium and sodium, but as regards other properties there is a wide divergence. The salts of soda are alkaline, and hence neutral- ize the acid of the gastric juice. They are readily diffusible. Like the potash salts, they increase the alkalinity of the blood, and under suitable conditions determine a change in the urine from acid to alka- line. The same results follow the administration during or between the intervals of digestion, as in the case of the potash salts. The alka- linity of the urine induced by soda salts ceases on the day following their administration, and the acidity is then increased. Soda has but little toxic action besides the local caustic effects. Caustic soda, like caustic potash, dissolves albumen, forms soaps with fats, and destroys the tissues widely and deeply. It is, however, less active than caustic potash. The composition of the blood does not appear to be altered by the salts of soda in any reasonable quantity. Laborde, in some comparative experiments between chlorate of potassa and chlorate of soda, finds that the latter, in treble the quantity of the former, has but a transient effect, depressing the temperature half a degree, and caus- ing a slight salivation, but producing none of the paralytic symptoms which follow the administration of the potash salts. Guttmann had previously demonstrated the same facts, and Schonlein, in some stud- ies with the carbonate, finds that even in large doses in frogs it rarely arrests the heart's movements, only slowing and lengthening the con- tractions. Chloride of sodium has, unquestionably, an important office in the economy. It forms the principal part of the soluble constitu- ents of the ash of all animal substances. Albumen owes its solubil- ity in part to the chloride of sodium ; it dissolves pure casein, and impedes the coagulation of the fibrin of the blood. In one thousand parts of blood there are about four parts of this salt. It is very abun- dant in various normal secretions and pathological products. The gastric juice is very rich in chloride of sodium, and it probably is the source of the hydrochloric acid of the stomach (Lehmann). In the course of an inflammation, notably of pneumonia, the chloride of so- dium of the system accumulates in the inflamed area, and disappears from the urine. Its return to the urine is in the nature of a critical phenomenon, and marks the subsidence of the inflammation. The im- portance of this salt in the animal economy is doubtless the cause of ALKALIES. 197 the universal taste ; all in excess of the needs of the body is excreted, chiefly by the kidneys, and with such facility that no accumulation takes place. While a necessary amount is of high importance and excess is readily disposed of, it is probable that long and habitual in- dulgence in a considerable excess increases waste and lowers the vital forces. Therapy of Sodium Salts. — One of the important salts of soda — the phosphate — has been considered under the head of phosphates. The soda salts are to be preferred in the alkaline treatment of stomach- diseases, but the potash salts when it is desired to promote oxidation in the system, or to alkalinize the urine. The urate of soda is insol- uble. In case of excess of acid or acid indigestion, the use of soda after meals is very effective ; but, while the immediate result is good, the after-effect is to increase the production of acid. Those who habitually take sodium bicarbonate for acid indigestion suffer severely from acidity. Taken before meals, or on an empty stomach, soda bicarbonate is useful in atonic dyspepsia, to increase the acid of the gastric juice. Acute indigestion, with vomiting, especially if the vom- ited matters are very acid, and there is burning at the epigastrium, may be quickly relieved by the effervescing powder. The acid diarrhoea of children is relieved by the bicarbonate of sodium. This salt may be utilized as an emetic in narcotic stupor when other emetics fail to act. The author has known this method to succeed in opium narcosis. A half to a drachm of bicarbonate in solution in water is swallowed or thrown into the stomach by the pump, and this is followed imme- diately by a similar quantity of tartaric acid. Brisk effervescence ensues, and the contents of the stomach are evacuated. In intussus- ception, the same expedient has been practiced with success. The solution of bicarbonate of sodium is thrown into the rectum, and is followed by the acid. Strong pressure must be made on the anus ; the gas forces the bowel back through the ileo-csecal valve and thus re- lieves. A stomach or bowel much softened by inflammation, or weak- ened by ulceration, is a contraindication of such an expedient. In the treatment of the febrile state, and to lessen the acidity of the urine, the soda salts have been proposed as substitutes for the pot- ash salts. The researches of Laborde, Guttmann, Podcopaew, and others, have shown that the former do not have the same powers as the latter, and that therefore the substitution can not be made suc- cessfully.

(Other salts of calcium are included under phosphates, hypophosphites, sul- phides, and bromides.) Antagonists and Incompatibles, and Synergists, the same as for potassium. Physiological Effects of Calcium Salts. — The important po- sition of phosphate of lime in the organism has been already set forth under the appropriate head. It is only necessary to state in this con- nection that the lime salts are antacid, or alkaline, and as such they neutralize the acid of the gastric juice. They act locally as sedatives to the mucous membrane. Some of them have a local action merely, but the chloride is very diffusible, and the carbonate feebly so. En- tering the blood in small quantity, they promote constructive meta- morphosis ; but the habitual use of large quantities hastens waste, or the retrograde metamorphosis of the tissues. Administered in the ordinary way, however, the lime salts furnish materials needed by the organism in its growth. The carbonate of lime is taken up in limited quantity by the stomach-juices and re-en- forces the same constituent in the blood. The chloride of calcium has a different office in the economy. It acts in a similar manner to the other chlorides, and has close relationship to the iodides. Clinical experience has shown that it possesses the ill-defined property known as alterative, removes certain toxic or morbific materials, and secures their excretion by the organs of elimination. The recent studies of the therapeutical actions of chloride of calcium have shown it to pos- sess the remarkable property of an antagonist or antidote to the stru- mous constitution. No mere physiological investigation could have demonstrated this power ; it is an empirical fact which we can not explain as yet by physiological methods. It has been shown, how- ever, that under its use enlarged and cheesy lymphatics gradually resume their normal condition, tubercular deposits undergo a process of calcification, and ulcerating cavities discharge their contents and cicatrize. It can not, of course, be asserted that such surprising changes frequently occur, but, that they do sometimes take place, clinical experience has proved. From this point of view, then, chlo- ride of calcium assumes a high degree of importance. ALKALIES. 199 Therapy of the Calcium Salts. — No remedy is more frequently prescribed for vomiting than lime-water. It is given very often with milk, one half, one fourth, as may be, and the combination is effective in arresting vomiting due to acute troubles of the abdominal organs, and also useful in vomiting of cerebral and reflex origin. When the milk-cure is prescribed, lime-water is frequently added to enhance the digestibility of the milk. Carbonate of lime is a useful restorative and antacid in the acid indigestion, and in the diarrhoea of strumous children. By Dr. Warburton Begbie and by Dr. Coghill the chloride of calcium is strongly urged, as the most efficient remedy in the feeble digestion and disordered secretions of strumous children. The latter especially commends the use of the chloride in " children when the sleep becomes restless and troubled, the breath fetid, the tongue foul and coated, the tonsils enlarged, the evacuations irregular and offen- sive, with deficient secretion of bile." In the colliquative diarrhoea of the strumous, it is said to be curative, even when accompanied by enlargement of the mesenteric glands. According to the published observations of Begbie, Coghill, and Bell, we possess no agent so val- uable in the wasting diseases of children of strumous origin, in glan- dular enlargements, etc. The testimony which has been lately pub- lished in respect to the curative power of chloride of calcium in consumption is certainly very striking, and especially in those cases succeeding to glandular enlargements heretofore so little amenable to treatment. According to Rodolfe, chloride of calcium cures chorea speedily. Lithium. — Lithium. Lithii Carbonas. — Carbonate of lithium. A white powder, spar- ingly soluble in water (1 in 100), and having a feeble alkaline reaction. Dose, grs. ij — grs. x. IAthii Citras. — Citrate of lithium. A white powder, deliquescent and soluble in twenty-five parts of water. Lithii Salicylas. — Salicylate of lithium. A white powder, deli- quescent on exposure to air, having a sweetish taste and a faintly acid reaction. It is freely soluble in water and in alcohol. Dose, gr. v — 3 j. Lithii Benzoas. — Benzoate of lithium. A white powder, or small shining scales, permanent in the air, having a cooling, sweetish taste and a faintly acid reaction. Soluble in four parts of water and twelve parts of alcohol at 60° Fahr. Dose, gr. ij — gr. xv. Antagonists and Incompatlbles, and Synergists, are the same as for the other alkalies. Physiological Actions of the Lithium Salts. — These remedies have strong alkaline and basic properties, and act on the organism of man in the same manner as the other members of the group. The compound of uric acid and lithium is readily soluble, differing in this 200 AGENTS INCREASING WASTE. respect from the urate of soda. It is said that the lithium salts alka- linize the urine more decidedly than even the potash salts. Therapy of the Lithium Salts. — Garrod first introduced these remedies into medical practice for the treatment of rheumatism, and in his recent Lumleian lectures has demonstrated anew their excep- tional value. Recently the compound of lithium and salicylic acid has been brought forward as a more effective remedy in the rheumatic diseases. The subacute and chronic cases, and the so-called rheitmatic gout, are the forms of the disease in which the lithium salts are most serviceable. In the so-called uric-acid diathesis, in renal calculi com- posed of uric acid, and in irritable bladder from an excess of acid in the urine, the salts of lithium are useful. In the case of a renal cal- culus a very protracted use of a well-diluted solution is necessary. External Applications of the Alkalies. — A solution of com- mon soda (impure bicarbonate) freely applied will often remove the fetid sweat of the feet, and the odorous emanations ichich in some subjects escape from, the axillary glands. Acne occurring in persons with a greasy skin, and prominent and black sebaceous follicles, may sometimes be cured by alkaline lotions. J> Liq. potassae, 3 j ; aquae rosae, § iv. M. Sig. : Apply with a soft sponge twice a day. For acute eczema where there is much serous discharge, no applications are more efficient than solutions of the alkalies. I£ Sodii carbonat., 3 ss ; aquae, Oj. M. Sig. : The eruption to be covered with lint soaked in this solution. Stronger solutions can be used in old cases where the skin is much thickened. As alkalies, by absorbing the moisture and combining with the fat of the sebaceous matter, make the skin dry and harsh, it is useful to apply some form of oil after these alkaline applications, certainly after the stronger solutions. Mutton-suet is one of the best fats for this purpose. In prurigo great relief is often obtained by an alkaline warm bath at bedtime. A solution of carbonate of potassium ( 3 iij — § iv) is recommended by Trousseau as a remedy for that obstinate affection — pruritus vidva. In freckles, sunburn, and tan, the following lotion is useful: fy Potassii carbonat., 3 iij ; sodii chloridi, 3 ij ; aquae rosae, 5 viij ; aquae aurantii nor., § ij. M. Sig. : Lotion. To cleanse the scalp from dandruff {pityriasis), there is no more suitable application than a saturated solution of borate of soda. Pow- dered borax, mixed with sugar, is a domestic remedy for aphthw of children ; it is simply placed on the tongue. A saturated solution of borax in rose-water is a useful application to remove freckles, and to allay pruritus vaginm. A solution of permanganate of potassa (gr. j — 3 j) is an elegant toilet remedy for correcting fetor of the breath. In ulcerous diseases of the buccal cavity it is used to destroy foul odors, and to improve the condition of the sloughing surface. In ill-conditioned wounds gener- ALKALIES. 201 ally solutions of this salt, in various strengths, are employed with a view to change the action, but little more is accomplished than tem- porary destruction of odors. There are many other agents, much less expensive and more powerful, which can be used for these pur- poses. The so-called ingrowing toe-nail may be cured by the application to the irritable granulation, at the margin of the nail, of a solution of liquor potassse ( 3 ij — 1 j). This solution is to be applied on cotton- wool, to the margin of the nail and to the ulcerated surface of the toe, until the nail is so far softened that it can be cut away without pain. Unhealthy and sloughing ulcers may be destroyed by potassa fusa, and a healthy granulating surface be left. No more efficient escharotic can be used in hospital gangrene. As it penetrates deeply and widely, great care must be used to limit its application to the affected parts, and, as soon as the destruction is sufficient, to check the further exten- sion of the caustic by washing with a dilute acid. Vienna paste-— which is a mixture of equal parts of potassa and lime made into a paste with alcohol — is milder in operation, and therefore usually preferred. Caus- tic potash was formerly much employed to make issues, to open ab- scesses and carbuncles, but these applications are now quite obsolete. Induration of the cervix uteri and chronic metritis (hyperplasia of the connective tissue) are, it is said (Dr. Bennet), very effectively treated by application of caustic potassa and potassa cumcalce; but such pow- erful means must be used with great caution, if at all. In carcinoma, when the disease is limited to the neck of the uterus and not too far advanced, caustic potassa may be used with advantage to destroy the diseased surface. This caustic is quite as efficient as any, probably, for the escharotic treatment of cancer when this method of treatment is employed. A solution of the bichromate of potassium (gr. j — grs. x — § iv) is an excellent local application in the treatment of the catarrhal state of the nasal, buccal, or vaginal mucous membrane. A saturated solution of this salt may be used as a caustic in place of chromic acid. Carbonate of soda in saturated solution has been used lately with signal success in the treatment of burns: it allays the pain, checks suppuration, and favors healing (McClellan, Pring, etc.). Cloths dipped in a saturated solution, and covered with oiled silk, are kept on the part, the solution being renewed as rapidly as may be neces- sary. Dr. Duckworth reports that toothache may be quickly allayed by holding a solution of carbonate of soda in the mouth. Recently chlorate of potash has been used with success in the treatment of epi- thelioma. This practice was first suggested by Vidal in the treatment of chancroid, and has since been successfully employed in the treat- ment of obstinate ulcers, epithelioma and cancer (Fereol, Leveque). In 202 AGENTS INCREASING WASTE. the simpler cases a saturated solution may be applied, but in epithe- lioma and cancer the powdered chlorate is thickly placed over the sore. It is said to allay pain, remove fetor, and promote cicatrization when so applied. The internal use of the salt is recommended in conjunction with the topical application in cancer, epithelioma, and lupus. Authorities referred to : Basham, Dr. W. R.

North America. Bladon Springs, Choctaw County, Alabama. A rolling, pine-woods region. They contain carbonate of soda, carbonate of magnesia, carbonate of iron, carbonate of lime, sulphate of lime, carbonic-acid gas, sul- phureted hydrogen (traces), and chlorine. Congress Springs, Santa Clara County, California. In the Coast Range of mountains. They contain carbonate of soda (15*418 grains to the pint?), car- bonate of iron, carbonate of lime, chloride of sodium (14*894 grains to the pint), sulphate of soda, etc. They are highly charged with car- bonic-acid gas. California Seltzer Springs, Mendocino County, California. They Contain carbonate of soda, carbonate of magnesia, carbonate of lime, carbonate of iron (a trace), and chloride of sodium. They are also highly charged with carbonic-acid gas. Perry Springs, Pike County, Illinois. They contain carbonate of potassa, carbonate of magnesia, carbo- nate of iron, carbonate of lime, sulphate of soda, silicates of soda and potassa. Temperature of the water is from 48° to 50° Fahr. St. Louis Spring, Gratiot County, Michigan. This water contains carbonate of soda (7*684 grains to the pint), carbonate of magnesia, carbonate of iron, carbonate of lime (5*019 grains to a pint), sulphate of lime (6'925 grains to a pint), silicate of lime, and silica. This is one of the so-called " magnetic springs " — the magnetic property being due not to the water, but produced by the magnetization with terrestrial currents of the vertical iron tube through which the water flows. It is unfortunate that this part of the peninsula of Michigan, in which the numerous alkaline and saline springs abound, is very decidedly malarious. Buffalo Lithia Spring, of Virginia. Contains well-defined traces of lithia, and is alkaline. This has been used with great advantage in gouty, rheumatic, and renal affections. The Hot Springs, Bath County, Virginia, contain carbonates of lime and magnesia, sulphates of lime, magnesia, and soda, and chlorides of sodium, calcium, and magnesium. The temperature of the water ranges from 100° to 106° Fahr. The Warm Springs, Bath County, Virginia, have a composition similar to the hot springs, but the temperature of the water is some- what less. At these springs, extensive bathing-pools have been con- structed. The best results have been obtained from the bathing, con- joined with the internal use of the water. Berkeley Springs are also situated in Bath County. The waters 204 AGENTS INCREASING WASTE. are alkaline, of a constant temperature of 72° to 74° Fahr., and are employed by bath and internally. Rockbridge Baths, Rockbridge County, Virginia. A mountainous region. They contain magnesia and iron, with a small quantity of iodine. Temperature, 74° Fahr. Used chiefly in the form of baths. Capon Springs, Hampshire County, West Virginia. This water contains carbonate of soda, carbonate of magnesia, and traces of iodine and bromine. The temperature of the water is 66° Fahr. These springs are situated in a romantic mountain-region. Besides the above, there are numerous weakly-alkaline waters, such as Bethesda and others of the Waukesha region of Wisconsin, in South- ern Michigan, and in many parts of the United States. It is impos- sible to mention all of them, and especially to set forth the rather pre- tentious claims, or recognize the apocryphal cures, so persistently and profusely published by their owners. Unquestionably good results have been wrought by these waters. Besides the positive there are negative virtues in these numerous mineral springs : they take the place of the indiscriminate drug administration which is one of the evils of the time. 2. European. Vichy, Central France. There are several springs — Grande Grille, Puits Carre, Hopital, Celestins, De Mesdames, and others. The waters contain carbonates of soda, of potassa, magnesia, and lime, sulphate of soda and chloride of sodium, phosphate of soda, arseniate of soda (a trace), carbon- ates of strontia and iron. The gas, which is abundant, is carbonic acid. In the Vichy region there are numerous alkaline springs having similar properties. The temperature of the waters varies from 58° Fahr. ( Celestins) to 178° Fahr. ( Chaudes Aigues). Mont Dor6, valley of the Dordogne, France. The waters are weak alkaline, and have a temperature from 90° to 104° Fahr. Their principal constituent is carbonate of soda. These springs lie among the volcanic mountains of Auvergne, at an eleva- tion of 3,300 feet. Vals, Ardeche, France. The waters of these cold springs are remarkable for the quantity of carbonate of soda which they contain. They are abundantly charged with carbonic-acid gas. Ems, on the Lahn, Germany. These waters contain, according to the analysis of Fresenius, 14 to 15 parts of bicarbonate of soda, 7 parts of chloride of sodium, and 1*7 part each of bicarbonate of lime and bicarbonate of magnesia, with sulphates of soda and potash, and bicarbonates of iron, manganese, ALKALINE SPRINGS. 205 baryta, strontia, and alumina in small quantity, to the pint. The gas is carbonic acid, from 6 to 8 cubic inches to the pint. Neuenahr, valley of the Ahr, between Bonn and Coblentz, Ger- many. The waters of these springs have a composition similar to those of Ems, but have about half as much soda and very little salt. Salzbrunn, upper Silesia, near Freiburg, Germany. These waters are very rich in carbonate of soda. Gleicheilberg, near Gratz, Styria, Austria. These springs are much more alkaline than Ems. The waters con- tain from 20 to 27 parts of carbonate of sodium, 19 '5 of chloride of sodium, and 7*8 of carbonate of magnesium. The water is highly charged with carbonic-acid gas. Therapeutical Uses of the Alkaline Mineral Waters.— As we have seen that alkalies taken before meals increase the production of acid gastric juice, the alkaline mineral waters are serviceable in atonic dys- pepsia. They are especially useful in catarrh of the duodenum and of the bile-ducts, and in the jaundice dependent on this state of the mucous membrane. In incipient cirrhosis, in congestion of the portal circulation, and in haemorrhoids due to the hepatic obstruction, they render important service. Obesity, which is frequently diminished by a course of alkalies, is better treated by alkaline waters, for at the springs these patients can be induced, more easily, to conform to the plan of exercise and diet necessary in these cases. The alkaline springs have long had a deserved reputation for the cure of gout and rheumatism. With the internal use of the waters should be conjoined baths, douches, etc. Gout and rheu- matic affections of interned organs are equally amenable to the same treatment. These alkaline waters, long used, are especially serviceable in the so-called lithic-acid diathesis. There is little doubt that the continuous use of alkaline waters for a long period will cause the solution of uric- acid renal calculi. For this purpose those alkaline waters rich in potassa are preferable. When diabetes is hepatic in origin, and occurring in obese subjects, the alkaline mineral waters are extremely useful. A suitable diet should be enjoined. The following domestic mineral waters may be advised in the above states : Bladon Springs ; the California Seltzer ; Perry Springs ; St. Louis Springs ; but especially Capon and the alkaline springs of Wis- consin. Of the foreign, the most important are Yichy, which is imported at a moderate price, Mont Dore, Yals, Ems, Salzbrunn, and Gleichen- berg. The psychical influences of change of scene, associations, and cli- 206 AGENTS INCREASING WASTE. mate, are largely concerned in the results of treatment with the waters of mineral springs. SALINE MINERAL WATERS. 1. North American. St. Catharine's Wells, St. Catharine's, Ontario, Canada. These contain chloride of sodium (217 to 375 grains to the pint), chlorides of potassium, magnesium, calcium (108 to 127 grains to the pint), sulphate of lime, and iodide and bromide of magnesium. A concentrated water prepared by evaporation is used, properly diluted by patients at a distance for internal diseases, and at the wells, ex- ternally. These waters are diluted with ordinary water to three fourths or seven eighths, before they are drunk. They are chiefly used as warm baths. The diseases in which they have been found most beneficial are chronic gout, rheumatic gout, chronic rheumatism, and gouty and rheumatic diseases, strumous diseases, engorgement of the pelvic viscera, chronic metritis, uterine fibroids, haemor- rhoids, etc. Spring Lake Well, Ottawa County, Michigan. The water of this spring contains chloride of sodium (50*691 grains to the pint), chloride of calcium (14*177 grains to the pint), chloride of magnesium, carbonates of soda, manganese, and iron, in small quan, tity, sulphate of soda (5*837 grains to the pint), bromide of magnesium - and a trace of lithia. These waters are applicable to the treatment of gout, rheumatism, strumous diseases, etc. The waters are drunk and used as warm baths. Saratoga Springs, Saratoga, New York. In general terms, these waters contain chloride of sodium, the alka- line carbonates, and are highly charged with carbonic-acid gas. The springs are numerous, and differ somewhat in composition. I subjoin a tabular statement (see page 207) of the analyses of the different waters, from the excellent work of Dr. Walton. These waters are useful in plethora of the abdominal viscera, in obesity, in habitual constipation due to deficient secretion, in plethora of the pelvic viscera, haemorrhoids, etc. The waters of the Pavilion and Geyser Springs, owing to the quantity of lithia which they contain, are especially serviceable in chronic gout, chronic rheumatism, rheu- matic gout, and affections dependent on these diatheses. The Colum- bian, Pavilion, Eureka, and Excelsior, containing a considerable pro- portion of iron, are more especially adapted to cases of the above- mentioned disorders, in which anaemia exists, but they must be drunk with caution by the plethoric.

RaspaiVs Eau S'edatif. — Liquor ammonia?, two ounces ; chloride of sodium, two ounces ; camphorated spirits of wine, three drachms ; water, thirty-two ounces. (Not official.) Antagonists and Incompatibles. — The vegetable and mineral acids, acidulous salts, earthy salts, and lime-water, are incompatible with the carbonate. In addition to the acids, potash, soda and their carbonates, salts of lead, silver, and metallic sulphates, are incompati- ble with the solution of the acetate. The persalts of iron, acids, and liquor potassae, are incompatible with the benzoate. Alkalies, alkaline earths and their carbonates, and lead and silver salts, are in- compatible with the muriate. In the treatment of poisoning by am- monia or its carbonate, the vegetable acids should be used to neu- tralize the poison, and its irritant action on the mucous membrane should be limited as much as possible by the administration of oil and demulcents. Therapeutically, ammonia is antagonized by veratrum viricle, aco- nite, digitalis, cold, and other cardiac sedatives. Synergists. — The action of ammonia is favored by heat, opium, iodine, by the antispasmodics, as valerian, asafcetida, etc., by the diffu- sible and aromatic stimulants, as alcohol, ether, etc. The therapeutical activity of the iodides and bromides is promoted by combination with carbonate of ammonia. Physiological Action. — Ammoniacal gas, brought in contact with 212 AGENTS INCREASING WASTE. a mucous surface, irritates it ; applied to the eye, it reddens the con- junctiva, and causes lachrymation ; applied to the nares, it reddens the mucous membrane, produces a sense of heat and burning, and increases the secretion of mucus. Inhaled, an overpowering sense of suffocation is experienced, and the glottis spasmodically closes. Prolonged contact with the air-passages excites violent inflammation. When solution of ammonia is swallowed, an active and destructive inflammation of the mucous membrane is set up ; the lips, tongue, soft palate, and tonsils are swollen, red, and glazed ; the epiglottis, and especially the arytseno- epiglottidean folds, become cedematous, and sudden death may ensue from oedema of the glottis. Inflammation of the oesophagus, and of a limited portion of the stomach, will also follow the introduction of any portion of the irritant. Narrowing (stenosis) of the pyloric orifice has been noted, in one case, as an after-result of the inflammation set up in this part. In the stomach, ammonia and its carbonate must quickly combine with the acid, and probably enter the blood in such combina- tion. Increased action of the heart is produced by its administration by the stomach, but much more decidedly when it is thrown directly into a vein. After the intra-venous injection of ammonia, the blood-pressure at first rises, then falls below the normal. Resulting, doubtless, from the increased action of the heart, and the more rapid circulation of the blood, a subjective sensation of warmth throughout the body is expe- rienced, the face becomes flushed, the eyes are more brilliant, and the mental operations increase in activity. Little is known of the behavior of ammonia in the blood, which in the normal state contains this gas. Although it is now known that the coagulation of the blood is not caused by the escape of ammonia, as supposed at one time by Richard- son, yet ammonia helps to maintain the fluidity of the blood, as its presence, in sufficient quantity, certainly serves to hold the fibrin in solution. The long-continued use of ammonia impairs digestion, by neutraliz- ing the gastric juice. Increased waste of tissue is also one result of its administration, manifested by pallor, emaciation, and feebleness. When introduced into the blood in sufficient quantity, it damages the structure of the red blood-globules, and in this way also it affects the nutrition of the body, besides the action which it has, in common with the other alkalies, of increasing the rate of waste or retrograde metamorphosis. The summary of the physiological actions of ammonia, above given, pretty fairly represents the movement of these agents as a group ; but individual differences undoubtedly exist, which will be pointed out when the therapy is considered. Therapy. — Ammonia and its carbonate are sometimes used to diminish acidity of the stomach -juices. Obstinate vomiting, after irri- tating substances are removed, and when the vomited matters are acid, may be relieved by the use of the carbonate, or better, by an excess of AMMONIUM. 213 carbonate in solution of the acetate. The acidity, gaseous eructations, and abdominal distention, which accompany attacks of hysteria in some females, may be quickly removed by the aromatic spirit of ammonia. Nervous headache, especially when it is present with the last-mentioned group of symptoms, is speedily relieved by the aromatic spirits and the carbonate ; but true migraine, although these preparations of ammonia may palliate it, is generally more certainly relieved by the bromides. RaspaiPs eau sedatif often gives great comfort in headache, when locally applied. In gastric and intestinal catarrh, chloride of ammonium is held in high repute by our German confreres. It is certainly highly serviceable in some hepatic disorders — for example, in catarrh of the bile-ducts and in the jaundice arising from this cause. In the first stage of cirrhosis, before contraction and induration have occurred, it is also useful. The nauseous saline taste of the sal-ammoniac is best covered by fluid ex- tract of taraxacum or extract of liquorice. The fluid extract of tarax- acum is to be preferred as the vehicle in hepatic disorders, because this drug has reputed virtues in these cases. When there is deficiency of secretion of the intestinal juices, constipation, and a coated tongue, with scanty and high-colored urine (so-called bilious state), sal-ammo- niac is one of the remedies which may be used with success. That this drug has a selective action on the liver seems probable from the fact that it increases the excretion of urea by the kidneys. To stimulate the action of the heart when it flags, the ammonia prep- arations have an undoubted effect ; hence in adynamic states they are frequently used. When employed for this purpose, small doses fre- quently repeated (every half -hour or hour) are necessary, owing to the fact that ammonia is quickly eliminated. It is a most common practice to inhale ammonia to prevent that depression of the heart's action called fainting. It should not be forgotten that ammonia, in- cautiously inhaled, may give rise to inflammation of the fauces and glottis. The preparations of ammonia (spirits, carbonate, water of) possess a high degree of utility when thrombosis is actually existent, but especially when threatened, as in the puerperal state, after free hemorrhage, when the circulation is languid from weak heart, a state of hyperinosis being present. It is perfectly safe and legitimate under these circumstances to practice the intra-venous injection of aqua am- moniae, 3 j — 3 ij, diluted with an equal measure of water. This practice seems more particularly advisable when sudden thrombosis of a large venous trunk ensues — as, for example, in the pulmonary artery, after uterine haemorrhage. In sudden paralysis of the heart from chloro- form narcosis, the bite of venomous snakes, etc. , this practice has been resorted to, but hitherto without any recognized success. As regards the intra-venous injection of ammonia as a remedy for the bite of venomous snakes, Brunton and Fayrer have shown that this practice / 214 AGENTS INCREASING WASTE. is without value. Ammonia is a physiological antagonist to hydro- cyanic acid, and is used in poisoning by this agent ; it counterbalances the depression, and maintains the heart's action, until the effects of the poison are spent. Carbonate of ammonia is one of the remedies occasionally success- ful in the treatment of delirium tremens. It is indicated, and proves most serviceable, when there is present anemia of the brain, and the heart's action is feeble. Half -ounce doses of solution of ammonia ace- tate are said to remove the effects of alcoholic intoxication. The vale- rianate of ammonia and the aromatic spirits of ammonia abort or prevent paroxysms of hysteria. Nervous headache and also migraine may sometimes be cured by the various preparations of ammonia ; but of these the muriate is exceptionally serviceable. Indeed, Dr. Anstie affirms that this agent, if given early enough, seldom fails to cut short an attack of migraine. It should be administered in doses of from ten to twenty grains. In myalgia, or muscular neuralgia, it is equally effective, according to the same authority : $ Ammonii choridi, | ss; ext. cimicifugse fluidi, f j ; glycerini, % ij ; syrupi tolu, aquae lauro- cerasi, aa § j. M. Sig. : A teaspoonful three or four times a day. In other neuralgiae the muriate of ammonia is occasionally useful, but by no means so curative as in migraine and myalgia. The preparations of ammonia are classed with the stimulant expec- torants. It is an interesting fact, in this connection, that they are elimi- nated largely by the lungs ; and it is probable, indeed, that in thus escaping they stimulate secretion and liquefy the products of inflamma- tion. In bronchorrhoea and chronic bronchitis, muriate of ammonia renders important service. It is given in extemporaneous prescriptions with extract of liquorice, and may be combined with other stimulating expectorants when no incompatibility exists : r> Ext. eucalypt., fl 1 j; ammonii chloridi, 3 ij ; ext. glycyrrhizse, 3 ij ; glycerini, § iij. M. Sig.: A teaspoonful four or six times a day. When great depression exists in pneumonia, carbonate of ammonia is given with advantage. It should be remembered that to stimulate the heart merely, when an obstacle exists in the pulmonary circulation, is of doubtful utility ; but ammonia liquefies the exudation, and thus removes obstruction of the air-sacs ; hence it becomes a remedy of great value during this stage up to the period of crisis. When there is much adynamia in these various pulmonary inflammations, the carbonate of ammonia is frequently prescribed in infusion of senega, a stimulating expectorant. Extraordinary success has been claimed for carbonate of ammonia in variola, scarlatina, rubeola, and erysipelas. A convenient mode of administration is to dissolve the carbonate in the solution of the ace- tate. The indications for the use of the carbonate are, feeble circula- tion, cyanosis, delirium. As these are self-limited diseases, the mild cases do quite as well without drugs. BARIUM. 215 Carbonate and acetate of ammonia are much prescribed in continued fevers — the latter as a so-called febrifuge ; the former when decided adynamia ensues. In typhoid the diarrhoea may be increased by the solution of the acetate. As in typhus and typhoid the ammonia in the blood is increased above the normal, it has seemed to the author im- proper practice to administer ammonia as a remedy in these diseases, and his observations have convinced him that it has no good effects which can not be better procured by other means. The chloride of ammonium is said to be an excellent emmenagogue in from ten to twenty grains. Local Uses of Ammonia. — Ammoniacal gas, cautiously inhaled, sometimes gives relief to acute catarrh, and in hay-asthma. Its good effects are limited, however, to that stadium of these maladies in which the morbid action is confined to the nasal passages, and the discharge is yet serous rather than purulent. The pain and smarting which attend the sti?igs of insects are alleviated by the application of diluted aqua ammonia?. The strong aqua ammonia? should be at once applied to the Mte of venomous serpents, and of rabid animals. Ammonia is frequently employed as a counter-irritant in the form of the well-known volatile liniment. As a vesicant it is also used when a prompt action is desired, but it is rather uncertain. A solution of sal-ammoniac in alcohol and water is an excellent dis- cutient application in inflammatory swellings : ^ \ Ammonii chloridi, 3 ij ; spts. vini rectif., aqua?, aa § ij. M. Sig. : Lotion. Cloths moist- ened with the solution can be frequently applied, and the cases in which it is applicable are the following : Orchitis, inflamed joints, sprains, and loccd and external inflammations generally.

It is soluble in diluted alcohol, and freely and en- tirely soluble in water. Dose, gr. ss — gr. v. It may be administered 216 AGENTS INCREASING WASTE. in pill form, or in solution, when it should be given well diluted with water. Antagonists and Incompatibles. — Sulphates, phosphates, and carbonates, and most of the salts of organic acids, are incompatible with it. Nitrate of silver decomposes it. When it is prescribed, it were better to avoid combinations, owing to the numerous incompati- bilities to which it is subject. The sulphates are ready antidotes, as sulphates of magnesium or sodium. Synergists. — The alkalies, and metallic salts from the therapeu- tical stand-point, increase its action on the retrograde metamorpho- sis. Ergot and digitalis favor its influence over the sympathetic system. Physiological Actions. — The soluble salts of barium have a disa- greeable, bitter, and astringent taste. In a full medicinal dose irrita- tion of the stomach is caused, and a sense of heat and burning is developed at the epigastrium. In one case (Ferguson) symptoms of poisoning came on in a week, produced by one twelfth of a grain of chloride of barium, administered three times a day, the whole amount taken being two and a half grains. The symptoms were extreme ex- haustion and nervousness. An idiosyncrasy must have existed here, as so small an amount would not, under ordinary circumstances, have produced such decided effects. The usual symptoms in cases of poi- soning are intense anguish, free salivation, great thirst, loss of voice, violent vomiting and purging, dilated pupils, frequent micturition, respiration slow and labored, pulse slow, increasing weakness, and finally complete paralysis of the extremities. The intelligence is pre- served until near the end, when convulsions and coma come on. The post-mortem rigidity is very decided. There are present very con- siderable bronchial effusion and hyperemia of the lungs, the heart is distended with black blood, and the brain is engorged. The stomach presents the usual appearances ; there is intense hyperaemia, and sometimes perforation of this organ. The quantity necessary to cause death varies greatly — two and a half grains have brought on serious symptoms, and half a teacupful of the carbonate has been recovered from. One drachm of the chloride has caused death in seventeen hours, and one ounce of the same salt in one hour (Woodman and Tidy). The effects on animals have been studied by Onsum, Cyon, Bohm, and myself (unpublished). Onsum held that the symptoms produced by the soluble salts of barium, when injected into the blood, were due to the formation of the insoluble sulphate. Cyon criticises this view, and shows that it is incorrect. The most elaborate, as it is the most recent, account of the physiological effects of the barium salts is that of Bohm. The statement to follow is based on this paper chiefly, and on the author's personal researches. In frogs, after injection of the BARIUM. 217 chloride into the lymph-sac, extension and rigidity of the voluntary muscles ensued, followed by relaxation and paresis. The belly becomes distended and the intestines are thrown into active movements ; the mouth is held wide open and a watery fluid continually escapes, while from the skin a mucus-like secretion exudes. When given to warm- blooded animals by the stomach, profuse secretion takes place, active peristalsis of the bowels and copious alvine discharges, and free urina- tion follow, but not until about a half -hour after the ingestion of the poison. If thrown into the veins the same symptoms arise immedi- ately : in either case the tonic and clonic convulsions followed by paralysis occur ; the pupils dilate ; the heart is slowed, but its contrac- tion is more energetic ; the tension increases enormously in the arte- rial system after a preliminary fall, and finally insensibility and coma terminate the action. Very large doses, suddenly precipitated on the heart by injection into the jugular vein, will induce paralysis both of the heart and lungs. With the peripheral paralysis labored breathing ensues, due to paresis of the respiratory muscles, and death is caused rather by this than by cessation of the heart's action, when the poison is introduced subcutaneously. The paralysis in animals begins in the hind extremities. This paralysis is preceded by fibrillary trembling and clonic spasms mixed with tonic rigidity. The muscular contrac- tility is entirely abolished when the paralysis is complete. On the nervous system of organic life barium chloride acts as a stimulant. The strong cardiac contractions, the dilated pupil, the energetic peris- talsis of the bowels, the closure of the lumen of the intestines and also of the bladder, and the almost complete approximation of the periph- eral vessel-walls, are the proofs of this excitation. Therapy. — Having actions in some respects like digitalis and ergot, barium salts are indicated in diseases to the treatment of which these remedies have been applied. Influenced by the observations of Bohm, probably, Dr. Flint, of Leeds, England, has employed the chloride of barium successfully in the treatment of aneurism. The case was one of abdominal aneurism, in a woman of sixty-five. Tuf- nell's treatment had been carried out faithfully for five months with- out success, and iodide of potassium, for some unexplained reason, could not be taken. Chloride of barium was, after careful considera- tion, selected, and one fifth of a grain three times a day was adminis- tered three or four weeks, when it was increased to two fifths. The curative effect was very manifest, for after nearly five months of con- tinued use of the same remedy the tumor was so reduced that it could be scarcely felt. Chloride of barium will probably prove use- ful in hemorrhage, in acute congestion of organs, in atony of the in- testines with deficient secretions, in atony of the bladder, in weakness of the heart with low arterial tension, etc. 218 AGENTS INCREASING WASTE. VEGETABLE ACIDS. Acidum Aceticum. — Acetic acid. Liquid; specific gravity 1*048. Colorless, having a pungent and characteristic odor. Of this acid one hundred grains neutralize sixty grains of bicarbonate of potassium. Acidum Aceticum Dilutum. — Diluted acetic acid. Seventeen parts of the acid to eighty-three parts of water. Acidum Citricum. — Citric acid. In colorless crystals, freely solu- ble in water and soluble in alcohol. One hundred grains of citric acid neutralize one hundred and fifty grains of carbonate of potassium. Acidum Tartaricum. — Tartaric acid. In colorless crystals, wholly or almost wholly dissipated by heat, and readily soluble in water. One hundred grains of tartaric acid saturate one hundred and thirty- three and a half grains of bicarbonate of potassium. Antagonists and Incompatibles. — The alkalies are the chemical antagonists ; yet, from the physiological point of view, the ultimate results of their action place them in the same division of remedial agents. Therapeutically, the acids are antagonized by those agents which promote constructive metamorphosis. Synergists. — The alkalies and agents promoting waste favor the therapeutical actions of the vegetable acids. Physiological Actions. — The vegetable acids, undiluted, have a sharp, pungent, and rather acrid taste ; but, when considerably diluted, they are rather agreeable and refreshing. They have the property to diminish the sense of thirst, to abate heat and the restlessness of fever. In large quantity, they possess considerable caustic power, j>roducing gastro-enteritis and the systemic symptoms belonging thereto. These systemic symptoms, especially the slowing of the heart, have been incorrectly, the author thinks, attributed to a special power of these agents to affect the action of the heart. There can be no doubt that these acids obey the chemical laws of combination, and unite with alkalies to form salts, in which form they enter the blood. The most important question connected with the physiological action of these agents is, the disposition of them in the blood. The most recent and elaborate examination of this point is the " Memoir " of Friedrich Walter. This research appears to have deter- mined that these acids do not have the power to neutralize the alka- linity of the blood, as has heretofore been supposed. That they are in part destroyed in the organism by the ozonizing action of the blood, seems undoubted. Carbonic acid is one of the products, and the pres- ence of this, we may assume, accounts for the increased acidity of the blood and of the urine, which follows the administration of these agents. They are eliminated by the intestinal canal, and chiefly by the kid- neys. They increase secretion from the intestinal mucous membrane, VEGETABLE ACIDS. 219 and are apt to produce tormina, flatulence, and diarrhoea. It is proba- ble that these intestinal effects are in part due to the fact that the salts, formed by combination of the acids in the canal, escape absorption and act locally as they descend. These acids, or the salts formed by their combination, have a de- cided power to promote diuresis. In this result all of the urinary con- stituents are included ; but it is chiefly the water which is increased. To these general statements some exceptions must be made. Thus, citric and acetic acids are entirely destroyed in their passage through the organism ; benzoic acid is converted into hippuric ; and tartaric, citric, and malic are converted into carbonic after combination with alkali only. Furthermore, benzoic acid does not increase any of the urinary constituents. Ultimately, wasting and emaciation, a watery condition of the blood, a scorbutic state, indeed (Bence Jones), are the results of the action of these agents. Therapy. — Acetic acid applied to the skin has some superficial caustic property. This is made use of to cure small warts and vegeta- tions of the skin. It is applied with a pine stick. Parasitic affec- tions of the skin are similarly treated, as, for example, pityriasis. Internally the acids, chiefly citric, in the form of lemonade, are used as a refreshing drink in fevers. They allay restlessness by relieving thirst, and they also act upon the skin and kidneys. Lime-juice is the most important antiscorbutic, and constitutes part of the equip- ment of every vessel on long voyages. It should not be forgotten that the use of lemon-juice may cause precipitation of uric acid, and thus favor the formation of calculi, as has been pointed out by Bence Jones. Lemon-juice was at one time the fashion in the treatment of acute rheumatism ; but more efficient remedies have taken its place. Acids are serviceable in various disorders of the digestive tract ; given before meals, they check the formation of acid, and thus re- lieve acidity. An acid and dry wine — as, for example, a Rhenish wine — may sometimes serve a useful purpose. The juice of a lemon may be taken before meals with the same object. But it is true that the mineral acids are to be preferred for this purpose. Very injurious effects are produced by the long-continued use of lemon-juice in such cases. It is sometimes taken by young ladies to keep down the for- mation of fat ; but it accomplishes this object by impairing digestion. Authorities referred to : Jones, Dr. II. Bence.

Acidum Sulphur sum. — Sulphurous acid. A colorless liquid, hav- ing the odor of burning sulphur, and a sulphurous, sour, and somewhat astringent taste. Dose, vi v — 3 j. Sodii Hyposulphis. — Hyposulphite of sodium. In large, colorless, transparent crystals, having a bitter, slightly alkaline, and sulphurous taste. It is soluble in one and a half part of water at 60°, and insolu- ble in alcohol. Dose, grs. v — 3j. Sodii Sulphis. — Sulphite of sodium. In white, efflorescent, pris- matic crystals, soluble in four parts of cold and in less than one part of boiling water. It has a sulphurous taste, and a feeble alkaline reac- tion. Dose, grs. v — 3j. Sodii BisulpMs. — Bisulphite of sodium. Opaque, prismatic crys- tals, or a crystalline or granular powder, slowly oxidized and losing sulphurous acid on exposure to air, having a faint sulphurous odor and taste, and an acid reaction ; soluble in four parts of water at 60° Fahr., and in two parts of boiling water. Dose, grs. iij — grs. x. Potassii Sulphis. — Sulphite of potassium. In white, opaque frag- ments or powder, very soluble in water. It has a saline and sulphurous taste. Dose, grs. iij — grs. x. Magnesii Sulphis. — Sulphite of magnesium. " A white, crystalline powder, gradually becoming oxidized on exposure to air, odorless, having a slightly bitter, somewhat sulphurous taste, and a neutral or slightly alkaline reaction." It is insoluble in alcohol but is soluble in twenty parts of water at 60° Fahr. Dose, grs. v — 3j. Antagonists and Incompatibles. — The mineral acids — including sulphuric — decompose the sulphites and hyposulphites. All oxidizing substances are incompatible. These preparations have a great affinity for oxygen, and the sulphites readily become sulphates. Synergists. — All remedial agents which arrest fermentative pro- cesses promote the therapeutical activity of sulphurous acid and the sulphites. Physiological Actions. — Sulphurous acid is a disinfectant and de- odorizer. It attacks organic matter with energy, by virtue of its affinity for oxygen. It is very destructive to the lower forms of life, bacteria, fungi, etc. Sulphurous-acid gas inspired produces great irritation of the glottis, and an intensely suffocative feeling. In sufficient quantity it produces violent inflammation of the air-passages. As by combina- tion with oxygen sulphuric acid is formed, the destructive effect as- cribed to sulphurous acid is in reality chiefly due to sulphuric. The sulphites exposed to the air rapidly absorb oxygen, and pass to the state of sulphates. The hyposulphites are more constant than the sulphites. In the stomach, by the acid of the gastric juice, these salts are in part decomposed and sulphurous acid is given off ; in part they SULPHUROUS ACID. 221 are converted into sulphates. They are undoubtedly absorbed as sul- phates, and are eliminated partly by the intestinal canal, but chiefly by the kidneys, as sulphates. The author demonstrated these facts soon after the publications of Dr. Polli led to an enthusiastic administration of these remedies in the zymotic diseases. Therapy. — Dilute sulphurous acid is one of the numerous local ap- plications considered efficacious in mercurial stomatitis, aphthae, mucous patches, ulcers of the tonsils, and in diphtheria. In all of these affec- tions the diluted acid may be applied directly to the diseased surface by a mop, a sponge-probang, or in the form of spray. A more easily- managed application is a solution of the sulphite of soda ( 3 j — 1 j in water). Sulphurous-acid spray is a good local application in syphilitic and tuberculous laryngitis. Cases of chronic bronchitis, with profuse expectoration of a fetid character (bronchorrhcea), are sometimes im- proved by inhalations of sulphurous-acid gas, or of the acid in the form of spray. Notwithstanding the confident assertions of Dewar, there is no reason to suppose that sulphurous-acid-gas inhalations can actually cure or even arrest the progress of phthisis. In certain kinds of vomiting of a yeast-like material, especially when sarcina are present in the vomited matters, the sulphites are often curative. Vomiting of acid matters, pyrosis, and indigestion, due to acid fermentation of the starchy and saccharine elements of the food, are relieved by sulphurous acid (tti v — 3 j, well diluted), or, but less efficiently, by sulphite of soda (3j — 3 j). The result in these cases is, no doubt, due to the power which sulphurous acid has of arresting the fermentation processes. After the publications of Dr. Polli, of Milan, extravagant expecta- tions were entertained of the curative power of the sulphites in the zymotic diseases generally, and in all the various forms of septic dis- eases. Unfortunately, these expectations have not been realized, and the sulphites are no longer employed with this view in any of these disorders ; and, as Braun and Bernatzik have shown, they are not only nauseous in taste but they produce more or less irritation of the intes- tinal canal, and do not in any case modify the course of the disease. Externally applied, sulphurous acid and the hyposulphites and sul- phites are in some maladies extremely serviceable. As a disinfectant and deodorizer sulphurous acid is at the same time efficient, easily managed, and economical. Sulphurous acid is the prod- uct of the combustion of sulphur in the open air ; hence, to disinfect rooms, it is necessary only to close all egress and fill them with the fumes of burning sulphur. It is to be remembered that sulphurous acid is injurious to many fabrics : the sulphites are colorless and soluble. Sulphurous acid is an efficient application to chilblains : I£ Acid, sulphurosi, 3 iij ; glycerini, 3 j ; aquae, f jss. M. In parasitic skiii-dis- eases, the sulphites, hyposulphites, and sulphurous acid, are used to 222 AGENTS INCREASING WASTE. destroy the parasites. The following formula is employed by Startin in these affections : ^ Sodii hyposulphitis, § iij ; acid, sulphurosi dil., | ss ; aquae q. s. ad J xvi. Fox recommends the following formula in tinea versicolor and in pruritus vulvas : t> Sodii hyposulphitis, 3 iv ; glycerini, 3 ij ; aquae destil. ad § vi. Sulphurous acid is an excellent application to ill-conditioned, slough- ing, or gangrenous wounds. It was found to be very successful in these cases, at the English hospital at Metz, during the Franco- German War. Authorities referred to : Bartholow, Dr. Roberts.

Sul- phurated potassa has a brownish-yellow color when freshly broken. It dissolves in water, with the exception of a slight residue, and forms an orange-yellow solution, which exhales the odor of hydrosulphuric acid. Dose, gr. j — gr. v. Calx Sulphureta. — Sulphurated lime. A greenish-gray powder, having a strong odor of sulphureted hydrogen. Dose, gr. j — gr. v. Antagonists and Incompatibles. — Solutions of the sulphides are decomposed by the mineral acids, sulphureted hydrogen being liber- ated and sulphur precipitated. Solutions of the metals, generally, are also incompatible with the sulphides of potassium and calcium, for, in the decomposition which ensues, the metals are precipitated in the form of insoluble sulphides. Hence it is that these preparations have been proposed as antidotes to the metallic poisons. Chlorine-water, chlo- rides of sodium and potassium, sulphate of iron, etc., are chemical antidotes. Synergists. — All agents promoting waste are, therapeutically con- sidered, synergistic. Alkalies favor their action, both chemically and physiologically. Physiological Actions. — These preparations have a decidedly nau- seous taste and smell, and are somewhat irritant. In the stomach they excite a sense of heat, and in sufficient quantity cause gastro-enteritis, with all the attendant symptoms belonging to irritant poisons. Dis- SULPHURETS. 223 agreeable eructations of sulphureted hydrogen take place when they are administered medicinally, owing to the reactions in the presence of an acid alluded to above. They increase secretion from the gastro- intestinal canal, and are laxative. The fetor of the stools is increased by their use, a result not altogether due to the evolved sulphureted hydro- gen, but to the increased action of those intestinal glands concerned in elimination. As the sulphides pass easily to the state of sulphates by the action of oxygen, it may be assumed that a part of their physio- logical effects is produced by the latter salts. They, however, un- doubtedly exercise a toxic action on the blood, impairing the red blood-globules, and increasing the amount of effete material. Ema- ciation, muscular weakness, and trembling, and a feeble circulation, are results of their use in large amount, or for lengthened periods. It is true that some acceleration of the pulse-rate and increase of secre- tion of the mucous surfaces follow their medicinal administration for a short period and in moderate doses ; but the prolonged inhalation of sulphureted hydrogen, or the prolonged internal use of the sulphides, causes great anaemia, wasting, and debility. Therapy. — Although the sulphides are indicated as remedies when the secretions of the intestinal glandular appendages are deficient, they are too disagreeable to be prescribed under ordinary circumstances. The water of the well-known Blue Lick Spring, of Kentucky, which is almost identical in composition with the famous Harrogate, of Eng- land, may be substituted for the sulphides in many of the cases in which the latter are useful. The Blue Lick water, like the Harrogate, is useful in abdominal plethora. A pint taken before breakfast is an efficient laxative, which is indicated in cases of habitual constipation from deficient secretion of the intestinal juices. Four ounces taken before each meal is an excel- lent remedy for obesity. Engorgement of the pelvic viscera in women, haemorrhoids in both sexes, when due to torpor of the portal circula- tion, are relieved by the same agent. For these purposes the Blue Lick water may be taken for several weeks or even months, but its use should be discontinued when anaemia is threatened. In anaemic sub- jects, chalybeates and a generous diet should be conjointly adminis- tered. The author has observed excellent results from the prolonged use of this water in glandidar affections, hepatic, splenic, uterine, and of the prostate. A succession of common boils, scrofulous and other abscesses, are, it is said, made to mature, and the expulsion of the pus is favored by the use of the sulphides. When abscesses are threatened, and before matter is formed, the sulphides, it is claimed, may cause them to abort. Small doses (gr. ss — gr. j) frequently repeated (every hour or two) are said to be most effective under these circumstances. External Uses of the Sulphides. — A solution of the sulphide of 224 AGENTS INCREASING WASTE. potassium ( 3 ss — § j) is an efficient application in scabies. An extem- poraneous sulphide may be made by boiling one part of quicklime and two parts of sublimed sulphur in ten parts of water. With this solu- tion the parts affected by scabies may be painted over, after preliminary cleansing with a warm bath. Sulphur-baths (solution of sulphide of potassium in water, as above mentioned) are very excellent applications in the chronic forms of psoriasis and eczema. The following formula is recommended by Fox in scabies and prurigo : $ Potassii sulphureti, 5 vi ; sapon. alb., ft>ij ; ol. olivae, Oij ; ol. thymi, 3 ij. M. A milder preparation is the following : $ Potassii sulphureti, 3 iij ; sapon. moll., 3 j ; aquae calcis, § viij ; alcohol, § ij. M. Or the following : ^ Potassii sulphureti, § ss ; aquae calcis, § xvj. M. For the relief of pityriasis antiparasitic skin-diseases. The sulphide of sodium (unofficial) being more stable, is better suited for the preparation of sulphurous baths. An artificial sulphur- ous water, in imitation of the Bareges, is made as follows : $ Sul- phidi sodii, sodae, sodii chloridi, aa § ij. M. Sig. : A sufficient quan- tity for one bath. The Pommade de Bareges of the French is consti- tuted as follows : $ Sodii sulphureti, sodii carbonat., aa 3 ij ; axungiae, I ijss. M. Sulphur-baths are frequently employed to favor the elimination of lead, in cases of saturnine disease. For this purpose, from three to five drachms of sulphide of potassium may be dissolved in sufficient water for a bath. A sulphide of lead is formed on the skin ; but that the sulphur-bath promotes the elimination of lead by the sweat-glands more than a simple warm bath, seems hardly credible. The disagreeable odor of the sulphides, in ointment or solution, may, it is said, be much modified by the addition of a little oil of anise-seed. Authorities referred to : Fox, Dr. Tilbury.

Therapy of the Sulphur- Waters. — These waters, as a rule, are useful in liver-disorders ; they diminish abdominal plethora, and con- gestion of the portal circulation. They are indicated in malarial affections of the liver and spleen. Rheumatism and gout, tuber miosis in its incipiency, chronic poisoning by the metals, etc., are certainly benefited by the internal use, and by baths of sulphurous waters. Affections of the skin, syphilitic diseases, chronic rheumatic affec- tions, etc., are especially forms of disease remediable by these waters, used internally and in the form of baths.

In white or transparent crystals, wholly soluble in water (4 in 3), and in alcohol (1 in 6). Dose, grs. v — 3 j. Antagonists and Incompatibles. — Iodine is incompatible with the mineral acids, the metallic salts, the vegetable alkaloids, etc. The chemical antidote is starch, or substances containing it, as flour. These should be given freely diffused in water. It should be remembered that starch is the antidote to free iodine. As, however, the iodide of starch is not devoid of activity, in cases of poisoning by iodine, the contents of the stomach should be evacuated. It is obvious that the preparations of iodine, taken after a meal consisting of amylaceous materials, will have their activity impaired by the formation of the iodide of starch, the acid of the stomach freeing the iodine from its chemical association. Therapeutically, iodine and the iodides are antagonized by all those remedies which promote constructive metamorphosis, and by the vaso- motor tonics, quinine, digitalis, cold, etc. Synergists. — Alkalies, and other remedies which increase waste, favor the action of iodine and the iodides. Under some circumstances, mercurials are especially synergistic. Physiological Actions. — Iodine. — When brought into contact with albuminous substances, iodine combines with it and prevents putrefactive change. The vapor of iodine, like chlorine, but in a fee- bler degree, decomposes sulphureted and phosphureted compounds. It is, therefore, justly ranked among the disinfectants. Applied to the skin or mucous membrane, iodine, according to the extent of the application, is irritant or caustic. It stains the skin yel- low, causes a sensation of warmth in small quantity, or of burning in larger quantity, and excites a superficial inflammation followed by des- quamation. In some subjects the application of iodine-paint causes vesication. Pure iodine, kept in contact with the tissues, produces a brown and dry eschar. The vapor of iodine is very irritant to the broncho-pulmonary mucous membrane, causing cough, spasm of the glottis, and increased flow of mucus. Iodine has a hot, pungent flavor, and excites a sensation of heat or burning in the stomach. In sufficient quantity, it acts as an irritant poison, inflames the raucous membrane of the stomach, and causes su- perficial eschars. The amount of iodine necessary to produce toxic symptoms varies greatly, and the variation depends in part on consti- tutional peculiarities, but chiefly on the amount and quality of the IODINE AND IODIDES. 229 food in the stomach. Whether applied to the surface of the skin or taken into the stomach, it quickly diffuses into the blood, and enters into combination with sodium or potassium, or with both. Iodides. — The iodides are among the most diffusible substances. They have a bitter, saline, and very disagreeable taste. In a few min- utes after being swallowed, the taste of iodide of potassium returns in the mouth, and, during a course of this salt, the saliva is constantly charged with it. In the stomach, in considerable doses, they produce first a cooling sensation, followed by warmth, and even burning. They pass into the blood with great rapidity. It is said that the base is changed in the blood, and the iodides of ammonium and potassium become iodide of sodium. In the blood they probably undergo no fur- ther changes, and do not, so far as is known, modify the composition of that fluid. At the points of elimination from the free mucous sur- faces (nasal, faucial, and bronchial mucous membrane), the chemical changes which ensue set free ozone, and the irritation there experi- enced is probably in part due to the iodine, separated from its combi- nations by the action of that agent (Buchheim). Elimination doubt- less takes place by the broncho-pulmonary, faucial, and salivary glands, but chiefly by the kidneys. The diffusion of the iodides into and out of the blood takes place with such rapidity that in fifteen minutes they may be detected in the saliva and in the urine. Diverse opinions have been expressed in regard to the influence of the iodides over the assimilative functions. By the syphilographers it is held that the iodides promote constructive metamorphosis, and that a gain in body -weight is a result of their use. This opinion is devel- oped in this way : The subjects of syphilis in its constitutional form emaciate, and their forces are depressed ; but, when the iodides are given them, the virus is eliminated, and the organism at once reacts. In the physiological state the iodides increase waste and the elimination of the products of waste, and emaciation with a general depression of the vital functions ensues, when they are administered for lengthened periods. Iodism. — Iodine and the iodides, when given in large quantity, produce a state termed iodism. The quantity which will set up this state of irritation in one subject will affect another but slightly, if at all ; in other words, the susceptibility to the iodine impression varies greatly in different individuals. Iodism is manifested by general malaise and rise of temperature, frontal headache, coryza, lachryma- tion, and sometimes inflammatory swelling of the eyelids, a bitter sa- line taste in the mouth, soreness of the throat, hoarseness, and difficulty of swallowing — phenomena strikingly similar to summer catarrh. In- deed, patients who experience these sensations for the first time, sup- pose them to be an acute catarrh. Usually the symptoms of iodism subside, notwithstanding the dose which caused them may still be 230 AGENTS INCREASING WASTE. taken, or, as it may be expressed, a " tolerance " is established. The quantity which at one time may have caused violent iodism will not necessarily again do so, although a considerable interval may have elapsed. Indeed, it is sometimes difficult to induce iodism in those who have become habituated to the use of the iodides in considerable medicinal doses. An eruption of acne, especially on the face, shoulders, and thighs, is a very common result of the internal use of the iodides ; hydroa on the face and forehead is an occasional consequence, but eczema is more frequent, yet less so than acne, which is usual. Wasting of the mammae and of the testes has never been observed by the author, although he has used the largest doses of the iodides, for long periods. There is no doubt about their antaphrodisiac ef- fects, and it has seemed to the author that permanent loss of sexual power has resulted from their long-continued use. When it is desirable to avoid iodism, large draughts of water should be taken during a course of the iodides. As Rosenthal has shown, large dilution of the salt hastens elimination, and thus prevents the more severe effects of iodism. Benedict has experimentally studied the effects of iodine and of iodide of potassium on the nervous system. His observations, made on frogs, demonstrated that these agents caused paralysis of the heart and of the respiration, but there are no facts indicating that on man they possess this power. It is true Schule had a case in which such symptoms were induced by injecting the sac of a spina bifida with tincture of iodine, but the direct and reflex effects of the injection on the spinal cord may have had much to do with the result. The nerv- ous symptoms which accompany iodism are apparently due solely to the increase in the pulse-rate, the elevation of temperature, and the irritation of the broncho-pulmonary mucous membrane. Therapy. — A weak solution of the iodide of potassium (grs. j — grs. v — § j) is a useful application to the mouth in aphthae, mercurial sto- matitis, simple sore-throat, tonsillitis, etc. Hypertrophy of the tonsils can usually be cured by the injection of the tincture of iodine into their substance. To execute this little operation, an hypodermic syr- inge, with a sufficiently long needle, is necessary. The vomiting of pregnancy can sometimes be greatly relieved by drop-doses, every hour or two, of the tincture of iodine. This, like all other remedies for this disorder, is very uncertain, and precise indica- tions for its use have not hitherto been ascertained. Catarrh of the duodenum, catarrh of the biliary ducts, and the jaundice dependent thereon, are, after the acuter symptoms have subsided, cured by small and frequently-repeated doses of the iodide of ammonium (grs. j — iij in water every two, three, or four hours). This is one of the best remedies for the first stage of cirrhosis. The efficacy of the iodide is IODINE AND IODIDES. 231 increased by combination with arsenic : ^ Ammonii iodid., 3 j ; liq. potassii arsenitis, 3 ss ; tinct. colombae, § ss ; aquae, § jss. M. Sig. : A teaspoonful three times a day, before meals. The preparations of iodine and the iodides are, generally speaking, contraindicated in all inflammatory states of the intestinal canal ; but in passive haemorrhage, and diarrhoea from atony of the mucous mem- brane, the tincture or compound solution of iodine in small doses — one or two drops — frequently repeated, renders important service (Schmidt). Large doses (grs. xv — 3 ss) of the iodide of potassium, three or four times a day, often afford remarkable relief in aneurism, and sometimes effect a cure. This mode of treatment is adapted to in- ternal aneurisms so situated as to be beyond the reach of surgical means. The author has seen several instances in which great relief was experienced, and one case certainly in which a cure apparently re- sulted. He is, therefore, able to confirm the observations of Chucker- butty, Roberts, Balfour, and others. The iodides are unquestionably serviceable in acute catarrh. The action is local and substitutive. A grain of the iodide of ammonium every two hours has seemed to the author the best mode of applying the remedy. In summer catarrh or hay-asthma, the best results are obtained by the use of larger doses, and the efficacy of the iodides is increased by combination with arsenic. fy Potassii iodidi, § j ; liq. potassii arsenitis, 3 j ; aquae, § iv. M. Sig. : A teaspoonful every four or six hours.

Sig. : Apply with a post-nasal syringe. Local applications will be effective, when the morbid action is confined to the nares and fauces. The iodide of potassium is one of the most effective remedies which we possess for spasmodic asthma. But it is not adapted to all cases arising under various conditions — a fact which explains the difference of opinion on the subject between Williams, Salter, and others. It is most beneficial when the asthmatic seizures are induced by an acute bronchial catarrh, the nervous symptoms being reflex ; and when there occurs during an asthmatic attack profuse bronchial secretion. Salter, however, holds that we possess no exact indications for its use, and that cases the most diverse are sometimes benefited in a remarkable manner. As regards dosage, from fifteen to thirty grains every two, three, or four hours, according to the severity of the seizure, is usually the necessary quantity. Chronic bronchitis, with profuse secretions (bronchorrhcea), is fre. quently improved by the iodides, more especially the iodide of am- monium. The efficacy of this remedy is increased by the conjoined administration of arsenic. In capillary bronchitis, the author has witnessed most astonishing relief by the rapid administration of iodide 232 AGENTS INCREASING WASTE. of ammonium in small doses. It may be combined with the carbon- ate, or with the stimulant expectorants. To prevent caseation of the inflammatory exudations of catarrhal and fibrinous pneumonia, no remedy is more efficient than the iodide of ammonium. To lessen the effect of this remedy on the tissue-changes, arsenic should be combined with it, and every means used to support the body nutrition. The iodide of potassium is one of the remedies resorted to in chronic pleu- risy, to promote absorption of effusions. In these cases the chest is painted with the tincture, and the iodides are administered steadily for a considerable period. Affections of the broncho-pulmonary mucous membrane, alluded to above, in which there is profuse exudation, all inflammatory symp- toms having subsided, are advantageously treated by iodine inhala- tions. The method which the author has found most convenient is the following : A small, wide-mouthed bottle, containing a moistened sponge, is placed in a vessel of hot water. The tincture of iodine (gtts. v — gtts. x) is dropped upon the sponge, and as the vapor of iodine rises, is inhaled with the vapor of water. This inhalation is serviceable in acute catarrh, hay -asthma, and chronic bronchitis. The carbolate of iodine (tinct. iodinii, 3 ij ; acid, carbol., 3 j) may be used instead of the simple tincture of iodine. Ten to twenty drops for in- halation. But few affections of the brain, non-specific in origin, are benefited by the iodides. According to Niemeyer, the iodide of potassium given to iodism has in few instances cured basilar meningitis. The author, who has used it faithfully in various cases, has not been so successful. Trousseau et Pidoux express their disbelief in the reported cures of tubercular meningitis by this agent. Seguin maintains, on the other hand, that remarkably good results sometimes follow the use of large doses of the iodides in other than specific diseases — in the various sub- acute and chronic inflammatory affections of the meninges and brain. No remedy is more efficient in the treatment of certain glandular enlargements of the thyroid, spleen, and lymphatic glands. Goitre is curable by the internal and external application of iodine, when it con- sists of simple hypertrophy of the gland-elements. Cystic and calca- reous degeneration of the thyroid are unaffected by the use of iodine preparations never so vigorously used. One of the best remedies for true goitre, as will be seen hereafter, is the unguentum hydrarg. iodidi rubri. Enlarged spleen, when it consists merely of an hypertrophy of the organ (chronic splenitis), is cured by the internal use of the iodides conjoined with the local use of iodine-paint, or ointment of the red iodide of mercury. The enlargements of the spleen and liver, with functional derangement of these organs, which are caused by malarial disease, are most effectually removed by moderate doses, frequently repeated, of the iodide of ammonium. The author's experience jus- IODINE AND IODIDES. 233 tifies him in strongly urging the combined use of iodide of ammonium and arsenic in chronic malaricd poisoning . The prolonged administration of iodide of potassium has appeared in some instances to have retarded the changes which ensue in chronic Bright s disease (fibroid degeneration), and to have improved the con- dition of the patients. The utility of the iodides is most conspicuous in certain constitu- tional states. The expectations which were at first entertained of the cure of scrofula by iodine and its preparations have not been realized. The iodides are unquestionably useful in the scrofulous (so called) enlargements of the lymphatic glands, but cod-liver oil and suitable hygienic means are more influential in improving the strumous di- athesis. The preparations of iodine are effective only when simple hypertrophy of the lymphatic glands has taken place ; if they have undergone caseation, or have proceeded to suppuration, no medicine has any influence over them. The most important therapeutical applications of the preparations of iodine are in the treatment of constitutional syphilis. For the pri- mary and secondary stage, mercury is generally admitted to be best ; but for tertiary symptoms no remedy at all approaches the iodide of potassium. In the secondary affections of the skin, mercury, especially if it have not been given for the primary troubles, is to be preferred in the papular, tubercular, squamous, and pustular syphilides ; iodide of potassium in the ulcerating, especially if the patient is cachectic. It may be stated in general that the preparations of iodine are indi- cated when the patient is under the mercurial cachexia. On the other hand, it is well known that sometimes, even when the tertiary symp- toms have not been relieved by a thorough course of iodides, mercury will quickly remove them. But this fact does not invalidate the rule that the iodides are specially serviceable for the tertiary period. No therapeutical fact is more conspicuous than the cure of syphi- loma of the nervous system by iodides. Mental disorders, epileptiform seizures, paralytic states, etc., dependent on gummata, nodes, etc., are usually removed in a manner little short of magical. Neuralgia of the fifth (tic-doidoureux), the pain being nocturnal chiefly, or nocturnal pain in the head, is similarly promptly cured. In syphilitic affections of the brain, more imperatively than in the same affections of other organs, are large doses of the iodide of potassium required. The limi- tation of the dose depends entirely on the physiological susceptibility of the patient, and the influence exerted over the progress of the case. Hence the dose may vary from ten grains to a drachm every four hours, or three or four times a day. The symptoms of iodism — the use of the agent to saturation — should be induced ; for this effect is the only measure of the therapeutical power of the remedy. The more promptly iodism can be induced, the better, for the soft nervous tissue may 234 AGENTS INCREASING WASTE. be quickly and irreparably damaged by syphilitic deposits and new growths. Syphilitic paraplegia is equally amenable to the same means ; but, as above remarked, much depends on the promptness with which the iodide is used. Recent experience has conclusively shown the curative power of iodine in malarial fevers. Thus three hundred consecutive cases were, with few exceptions, promptly arrested (Anderson). In some cases no paroxysm occurred after the medicine was administered ; sometimes the attacks persisted for two or three days, but then the relief was complete. The official compound tincture of iodine may be prescribed — for adults, ten to fifteen minims, three times a day, well diluted, and before meals. Carbolic acid, itself having considerable anti-periodic power, may be combined with the compound tincture of iodine. $ Tinct. iodinii comp., § ij ; acid, carbolic, 3 j. M. Sig. : Ten to fifteen minims three or four times a day. The official tincture of iodine is given by many practitioners. If quinine be necessary to break up the paroxysms, iodine is highly useful in the interim, as has been indi- cated. Some recent experiences by Dr. Atkinson, of Baltimore, throw doubts on the previous statements. He found that iodine failed in two thirds of the cases of intermittent fever. The use of the compound solution of iodine during the course of the first and second week of typhoid fever is known in Germany as the " specific treatment.'' A very considerable reduction in mortality appears to have followed this method. The solution of iodine or the tincture is administered regularly three times a day, well diluted with water. When it does good, the temperature falls, the nausea lessens, and the diarrhoea is restrained within safe limits. Chronic rheumatism, when there are present thickening of the fibrous tissues, and inflammatory depositions about joints, tendons, peri- osteum, and nerve-trunks, is often very signally benefited by the iodides. The cases in which these remedies prove so serviceable are most prob- ably due to syphilitic, mercurial, saturnine, or other constitutional causes. There are, in our modern life, many ways in which these mineral poisons enter the organism, and it is probable that they are often undiscovered and even unsuspected causes of rheumatic symp- toms. Jjambago, sciatica, and paraplegia, apparently of rheumatic origin, and curable by the iodides, may not unfrequently be caused by syphilis, mercury, copper, tin, or lead. The various accidents caused by the metals above named, especially the mercurial and saturnine, are removed by the use of the iodides, notably by the iodide of potassium. With regard to the dose neces- sary, what is true of syphilis is equally true of the mineral poisons : in order to remove them, the organism must be saturated by the remedy. From fifteen grains to a drachm, three or four times a day, should be given ; but the measure of the quantity required is the effect pro- IODINE AND IODIDES. 235 duced. The iodides penetrate into every tissue, convert the deposited metal into soluble combinations, and cause them to be discharged by the various organs of excretion, chiefly by the kidneys. It has been repeatedly asserted that salivation may be induced, and existing sali- vation increased, by the use of the iodides for the removal of mercu- rial salts from the organism ; but the author has not witnessed any facts which support this statement. In skin-diseases of syphilitic origin there can be no question as to the utility of the iodides. But these remedies are more especially cura- tive in the tertiary affections, especially in destructive syphilitic ulcera- tions. Hebra insists, and with justice, that the preparations of iodine are only useful in lupus, whether syphilitic or scrofulous, and do not permanently improve other cutaneous diseases. Mr. Hutchison calls attention to the fact that the various skin-diseases classed as hydroa may be produced by the iodide of potassium. The author lias cer- tainly had one case illustrating this action of the iodide. Local Uses of the Preparations of Iodine. — The tincture of iodine is in universal use as a counter-irritant. It is applied by means of a camel's-hair brush to goitre, to enlarged glands, and to superficial inflammatory swellings before the formation of pus. Painted over the neck, it is a useful counter-irritant in acute affections of the pharynx and larynx, and to the chest to relieve the chest-pains which occur in phthisis. It is the most serviceable counter-irritant to promote absorp- tion of inflammatory products in catarrhal and fibrinous pneumonia after the acuter symptoms have subsided. The same application ap- pears to possess the power to promote the absorption of pleuritic effu- sion. It is a good plan in these affections to paint, on successive days, the tincture over the front, the lateral, and the posterior wall of the chest, so that one surface has time to recover from the irritation before it is again attacked. As the susceptibility to the action of the iodine varies in different subjects, it is always prudent to make a slight appli- cation in the beginning. If extreme burning follow the applications, the iodine may be dissolved off by a solution of iodide of potassium, by alcohol, or ether. The tincture and the ointments of iodine are also used to remove the induration of the breasts which results from attacks of inflamma- tion. It must be remembered that the integument in this situation is extremely sensitive to irritating applications. Splenic and hepatic dis- orders of a chronic kind are frequently treated locally by the a])plica- tion of tincture and ointment of iodine. Enlarged spleen of malarial origin is more speedily cured by the application of the official red iodide-of-mercury ointment, and, as regards hepatic disorders, the only affection which has seemed to the author to be benefited by iodine ap- plications is the engorgement due to malarial attacks. After the acute symptoms have subsided, tincture of iodine will re- 236 AGENTS INCREASING WASTE. move the swelling of orchitis. The scrotum, like the female breast, is very sensitive to the irritation of iodine tincture and ointments. Bubo, like the enlarged lymphatic glands in other situations, may be treated by the application of iodine-tincture, but it is not very effective. Although Hebra does not approve of the internal use of iodine in cutaneous diseases, he advises the local application. He employs the tincture or glycerine solution in chloasma, lentigo, and lupus. The tincture of iodine is used to prevent the pitting of smallpox. Accord- ing to Piringer, it should be applied as follows : If on the first day of the eruption, the whole face, including the eyelids, is brushed over with the tincture of iodine ten times, there being an interval of a half -hour between each application ; if on the second day, twelve applications ; if on the third day, twelve to sixteen applications. The tincture of iodine is sometimes painted over the affected surface in erysipelas, and over the surrounding healthy integument, to prevent the spread of the disease, but, according to the author's experience, it is bad practice. Iodoform may be substituted for iodine in the form of the official ointment. This may be used locally, rubbed in, as the iodine-oint- ments are, for the relief of local inflammatory swellings, enlarged lym- phatic glands, goitre, etc. The strong, diffusive, and peculiar odor of iodoform is an objection to its use in this way. Iodoform powdered and dusted over the diseased surface is an excellent application to sloughing and ill-continued wounds, irritable ulcers, rodent ulcer, chan- croid, sloughing phagedena, and serpiginous syphilitic idcers. It allays pain, changes the morbid action, and is antiseptic. Syphilitic idcers of the tonsils, pharynx, and tongue, are most effectually treated by local and direct application of powdered iodoform. In these cases the pow- der may be blown on to the surface of the ulcer by an insufflator or insufflation-tube. Fissures of the anus, haemorrhoids and idcers of the rectum, are improved in condition, and the pain which attends them relieved by application of the ointment of iodoform and by iodoform suppositories. The latter are also of undoubted service in chronic metritis and hypertrophy of the prostate when introduced into the rectum ; the iodoform diffuses into the neighboring organs, and acts directly upon them. The pain of cancer may be somewhat relieved, and the fetid odor which attends the discharges may be removed, by the application of iodoform to the diseased surface. This treatment may be applied to cancer in any situation, but is especially applicable to cancer of the uterus and rectum. The parenchymatous injection of tincture of iodine is a remedial means of great importance. The method of employing it is exceeding- ly simple. An ordinary hypodermatic syringe (glass or hard rubber) is charged with five to fifteen minims or more of the tincture, and the needle is thrust deeply into the affected tissue, and the iodine is slowly discharged. For injection into parts very deeply situated, long needles, IODINE AND IODIDES. 237 such as are made for aspiration, can be used. This method of treat- ment is very effective in hypertrophied tonsils, goitre, glandular tumors, and the compound cystic and glandular growths so frequently found in the neck. The author has witnessed the cure of many cases of this kind by the parenchymatous injection of tincture of iodine. Some precautions must be attended to in practicing these injections. When the point of the needle is inserted as deeply as desired, it should be moved about to disengage it from any vessels into which it may have penetrated. The injection should be practiced slowly, to give time for the tincture to diffuse into the substance of the tumor. It need hardly be remarked that the superficial vessels of the neck should be avoided in inserting the needle. When hydrothorax returns after evacuation of the cavity by the trocar, the compound solution of iodine or the tincture may be injected into the pleural sac. In empyema, the undiluted tincture of iodine may be thrown in without risk, and with great benefit. Ordinarily, a solution of the following strength may be used to wash out the cav- ity in cases of empyema : I> Liq. iodinii comp., § j ; aquae, § xv. M. Hydatids of the liver may easily be destroyed by injecting into them a few drops of tincture of iodine. It has, however, been shown that in some instances simple capillary puncture and withdrawal of the fluid suffice to arrest the growth and to abort these parasites. Injec- tion of tincture of iodine is one of the means resorted to to cure hy- drocele. It is said that hypertropliied prostate may be diminished and fur- ther enlargement prevented by parenchymatous injection of iodine. In the performance of this operation a Sims or bivalve rectal speculum is inserted, and the needle of the syringe is passed through the walls of the rectum into the gland. Careful palpation previous to the inser- tion of the needle, will enable the operator to avoid important vessels. Unilocidar ovarian cysts may sometimes be cured by injecting into them, after the withdrawal of the fluid, ten to sixteen ounces of tinc- ture of iodine. No other form of ovarian cyst will, however, be affected favorably by this expedient. Large abscesses may be made to close much more speedily than they would otherwise, and septic infection be prevented, by the injection of iodine-tincture after the evacuation of the matter. Numerous cases of spina bifida have been cured by the injection into the sac of tincture of iodine ( 3 ss) or a solution of iodine (gr. ss) and iodide of potassium (gr. v) in water ( 3 j). Io do- Tannin.- — This is an excellent application for local diseases.

The author has found a saturated solution of tannin in tincture of 238 AGENTS INCREASING WASTE. iodine a most efficient application in all those cases of uterine disease in which the tincture of iodine and iodized cotton and iodized glycerin are now so much used. It is serviceable in chronic cervicitis, chronic endo-rnetritis, sub-involution and hypertrophy of the uterus. The au- thor has also found that the following combination is a capital applica- tion in leucorrhoea and the above-named uterine affections : IJ Iodo- formi, 3 ]* ; acid, tannici, § j. M. A sufficient quantity to be packed in the dry state around the cervix. The iodide of starch is used by Mr. Marshall as a dressing for syphi- litic ulcers, and he speaks highly of its efficacy. A decolorized tincture of iodine for external use may be prepared as follows : iodine, hyposulphite of sodium, distilled water, of each ten parts. Dissolve with a moderate heat, and add sixteen parts of spirits ammonia, and, after a few minutes' agitation, add seventy-five parts of alcohol. The solution must stand in a cool place for three days, and then be filtered (Waldenburg und Simon). Decolorized iodine is of doubtful utility. An extemporaneous iodo-tannin may be prepared according to the formula of Sigmund : ^ Tinct. iodinii, tinct. gallae, aa § ss. M. The strength of this may be increased by the addition of iodine 3ij. Ethee Hydeiodicus. — Iodide of ethyl. Ethyl-iodide. This is a colorless, non-inflammable liquid. The odor is peculiar, very powerful and diffusible, and the taste pungent. It is not solu- ble in water, but dissolves to some extent in alcohol. Its specific grav- ity is 1*92, and its boiling-point 160° Fahr. Exposed to light and air it assumes a dirty, brownish-yellow color, from the setting free of iodine ; hence it should be kept in closely-stoppered bottles in the dark. The dose is fifteen to twenty drops inhaled from a handker- chief, three or four times a day. Physiological Actions. — Although ethyl-iodide might be classi- fied with the other anaesthetic agents, its physiological and therapeuti- cal effects ally it more nearly to the iodides. As an anaesthetic, the action is slow and imperfect. Dr. Lawrence, of Boston, testing the action in his own person, found that a half -hour of inhalation failed to produce even drowsiness. It is said, however, that it induces the anaes- thetic state in animals, but further information is needed on this point. Hydriodic ether offers a ready and effective means for introduc- ing iodine in the system. M. Huette first employed it for this pur- pose, and his observations were afterward confirmed by Mr. Turnbull, of Liverpool. Then Dr. Fisher, of New York, also used it with the same object. Probably, the most satisfactory observations which have been made are those of Dr. Lawrence, of Boston, who not only studied the physiological action of this ether, but indicated the mala- dies in which it is useful. IODINE AND IODIDES. 239 Therapy. — Ethyl iodide is administered by the broncho-pulmonary mucous membrane. Fifteen to twenty drops are put on a handkerchief and inhaled as may be necessary — every two, three, or four hours, or more or less frequently. As a means of introducing iodine into the blood, it offers many advantages. When, therefore, it is necessary to induce iodism speedily, as in syphiloma of the brain or spinal cord, it is an appropriate remedy. In the spasmodic affections — the neu- roses of the respiratory organs — as asthma, emphysema, whooping- cough, etc., when accompanied by catarrh of the mucous membrane especially, excellent results may be expected from the inhalations. Dr. Lawrence has found it of exceptional utility in asthma. Good effects maybe had from it in capillary bronchitis, in chronic bronchitis, in fibroid phthisis, and in caseous phthisis. Iodoformum. — Iodoform. — Iodide of formyl. Small, lemon-yellow, lustrous crystals of the hexagonal system, having a saffron-like and almost insuppressible odor, and an unpleasant, slightly sweetish iodine- like taste. Not perceptibly soluble in water, to which it imparts a slight odor and taste ; soluble in 80 parts of alcohol at 15° C. (59° Fahr.) and in 12 parts of boiling alcohol, in 5*2 parts of ether, and in chloroform, benzol, benzin, disulphide of carbon, fixed or volatile oils. It sublimes slightly at ordinary temperatures. (U. S. P.) Unguentum lodoformi. — Iodoform ointment. Iodoform, 10 parts, benzoinated lard, 90 parts. Actions and Uses. Notwithstanding iodoform contains 97 per cent of iodine, it possesses properties in some respects different from that agent. Discovered by Serullas in 1822, it was not prescribed until 1836, when Bouchardat used it because of the large quantity of iodine contained in it. In 1853 D'Olleggio brought it forward as a disinfectant and deodorizer ; and in 1856 MM. Moretin et Humbert showed it might be substituted for the iodides, because easily absorbed and free from any irritant properties. They also demonstrated that iodoform has anodyne effects, that it induces analgesia of the rectum when applied to it, and that it can be used in the same classes of dis- ease as iodine, and in some neuralgias and painful affections of the bladder and prostate. In 1866 Dr. Eastlake, in the course of a paper on uterine therapeutics, referred to iodoform as a valuable sedative in uterine cases. Dr. Greenhalgh soon after confirmed these observa- tions. The following year, Yoelker added some new facts of the same kind. In 1868 Fereol, in a paper read before the Therapeutical Society, gave full details regarding the effects of iodoform on wounds, fully anticipating many of the observations since made on its antiseptic and healing^properties. Little attention had been given to iodoform in Germany, before the investigation made by Binz. Moleschott followed these researches 240 AGENTS INCREASING WASTE. by some important chemical observations, and afterward Mosetig and Mikulicz, of Vienna, and Gussenbauer, of Prague, set forth the remark- able virtues of this substance as an antiseptic dressing. Since these communications appeared, the use of iodoform has received enormous extension, and its popularity has attained to such extravagant propor- tions, that the wide-spread enthusiasm may be entitled iodoform-mania. There can be no question, however, as to its utility. There are, never- theless, limitations to its employment, imposed by' the nature of the substance. It seems desirable, hence, to set forth in a special article its actions and uses, according to the modern conceptions of its powers. As iodoform contains 97 per cent of iodine, it may be supposed to have analogous properties, but, as the iodine is combined with the radi- cal formyl, another influence enters into the action. Applied in the form of crystals or as a powder, the immediate effect is that of the compound — iodide of formyl — and not that of iodine merely, or of formyl merely ; but the latter distinctly modifies the former ; hence there is more or less of an anodyne effect. Binz holds that when iodo- form is applied to a wound it is dissolved in the fatty bodies of the organism, and that iodine is disengaged to form iodides and iodates. Hogyes, on the contrary, maintains that the iodine when set free unites with albumen', and afterward forms salts. Moleschott explains the more energetic action of iodoform by the assumption that it is readily decomposed in the blood, and that the free iodine in its nascent form has more energetic affinities (Rohmer). In what manner soever its mode of action may be explained, the main point, in regard to which all are agreed, is, that the action of iodoform is chiefly due to the io- dine. The effects of iodine have already been set forth, and hence no further statements are necessary ; but the antiseptic action of iodoform, to which its present applications are chiefly due, requires further ex- position. Mikulicz has especially studied the effect of iodoform on decomposing animal substances, and he finds that it prevents change and arrests decomposition when begun. For the purpose of determin- ing its power to prevent putrefaction, he employed Pasteur's liquid, composed of extracts of foods, of malt, of peptones, of alkaline urine, and of bouillon, and blood, and covered this mixed solution with pow- der and crystals of iodoform. The experiment was varied by adding iodoform in different quantity to solutions having the same composi- tion, and a " control experiment " was employed, to verify the results. It was shown that, in those solutions treated with sufficient iodoform, there was absolutely no development of minute organisms, while in the " control " fluid the germs were abundant and the putrefactive process active. In contact with wounds it has a very prompt and thorough antiseptic action. It promotes union and cicatrization, and at no time are there any heat, redness, swelling, or pain produced by it at the point of application. There is very little secretion from the IODINE AND IODIDES. 241 wound treated by the application of iodoform, and the little observed has rather a serous than a purulent character. When a considerable loss of substance is to be closed by granulations, iodoform does not act so well, it is said, and hence, when the granulations have filled the wound up to the level of the skin, it is better to substitute solutions of nitrate of silver, of acetate of lead, etc. Notwithstanding iodoform acts in many respects like iodine, there are differences. When the iodides or iodine tincture are given in suf- ficient doses, among the phenomena of iodism caused are coryza, pharyngeal and laryngeal catarrh, etc., and there ensues very consid- erable wasting of the tissues in general. On the other hand, when iodoform is given, wasting does not occur, but the body-weight in- creases, the complexion grows better, and the general condition im- proves in every way (Rohmer). It can not be affirmed, the author believes, that these beneficial results are constant for all doses of the remedy administered by the stomach, or for all quantity when applied topically. In fact, the first enthusiasm awakened by the discovery of the antiseptic powers of iodoform has been chilled by the untoward results of too lavish application. Not only dusted over the wounded surface, but applied in thick layers, it was soon found that, notwith- standing the slow absorption of iodoform, sufficient entered the blood to produce alarming, serious, even fatal symptoms. Poisoning by Iodoform. — It is very important to have a clear con- ception of the mischief which may be thus caused. As iodoform will probably continue to have an important place in the antiseptic method of surgical dressings, and as it is also much employed in medical prac- tice, the practitioner should learn to recognize the untoward symptoms. "Eseter, of Trieste," says Louguet, "had a case of death from the iodoform-mania." But many deaths have since followed from the too lavish use of this agent. An idiosyncrasy is observed in some subjects — a special susceptibility to the action of the iodides in general, and to iodoform in especial. It sometimes happens that this idiosyncrasy develops suddenly and without warning, and the toxic symptoms oc- cur at once, death quickly ensuing, although the remedy is suspended (Schede). When the action of iodoform is unfavorable, the symptoms observed have been as follows : 1. Rise of temperature to 104° Fahr., or even higher. 2. In addition to fever, there will be headache, loss of appetite, a rapid pulse, low tension of the vessels, etc., but the symptoms in both classes will quickly disappear if the remedy is dis- continued. 3. In this form of iodoform-poisoning, the pulse is quick, reaching even 180, and is feeble; there is much depression of the forces in general, and the condition of the mind is anxious, restless, and melancholic. These symptoms may be caused in some subjects by the first application of iodoform, or may come on after an apparent toler- ance has been established. 4. In this group of toxic cases, the same 16 242 AGENTS INCREASING WASTE. symptoms occur as in the third, viz., high fever, melancholia, etc., but the termination is quickly fatal, although the application of the rem- edy is stopped. 5. In this group, the symptoms of a profound depres- sion come on, and death speedily occurs in a condition of collapse. In many examples of this kind, it may well be a question whether this accident is not due to the injury of operative procedures. 6. In the more formidable results of iodoform applications, very decided cere- bral symptoms have been observed. These have been described by Schede and Kiister more especially, and are mentioned by them in connection with the several classes of iodoform-poisoning above re- ferred to. There is, however, a condition of the cerebrum caused by iodoform-poisoning characterized by disordered stomach, high fever, dilated pupils, melancholic depression, stupidity of mind, involuntary evacuations, hallucinations, etc. Notwithstanding the above-described forms of poisoning have a real existence, it is held by Mundy, Czerny, Kiister, and others, that now and then, probably frequently, a septicaemic state, and undiscov- ered complications, are responsible for the symptoms attributed to iodoform. Making due allowance for such an error, there are still examples of the toxic effects of iodoform ; hence the need of proper caution in using it topically. Treatment of Iodoform Intoxication. — The first step consists in the withdrawal of the application, and every adherent particle should be at once removed. The powers of life should be supported by a judicious use of stimulants, and especially by small doses of the tinc- ture of opium, frequently repeated. Elimination should be promoted by diluents freely administered. The most important point as regards prophylaxis is to avoid too lavish use of the agent. Schede says that large flesh-wounds should not be filled with iodoform, for then it can be removed only with the scab. Granulating surfaces absorb less, but here the danger of in- toxication also exists. Mundy advises that a small quantity only of the powder be dusted over the wound, that the dressings be allowed to remain, and that close sutures and tight bandages be avoided. It appears that caution is needed in the application to the amputated breast, and in all operations involving the peritonaeum. As to quantity used, we are guided by the results following lavish use. Three hun- dred grammes in one case (Beger), 100 to 200 grammes (Henri) in another, have induced poisoning. Death followed the use of 35 to 40 grammes (542 to 620 grains) in a case of operation involving the peri- tonaeum (Kiister). Von Mosetig-Moorhof has employed iodoform in several thousands of surgical cases without a single instance of poisoning, and he attrib- utes this favorable result to the fact that he has not used large quanti- ties of the remedy, thai the wound was not subjected to pressure, that IODINE AND IODIDES. 243 the dressings were frequently changed, and that carbolic acid was not used at the same time. Mode of applying Iodoform. — The simplest mode consists in merely dusting the powder over the surface, wound, or sore, to be acted on. A common tin pepper-box or an insufflator may be utilized for this purpose. Gauze or absorbent cotton may be saturated with an ethereal saturated solution of iodoform and applied according to the methods of Lister. Iodoform and tannin may be applied in any de- sired proportion after they have been thoroughly triturated together. Iodoform may also be suspended in a mixture with gum — with glycer- in and gum-tragacanth. As the odor of this substance is so diffusive and persistent, various means have been resorted to for its removal or modification. The essential oils, the balsams of Peru and tolu, es- sences of all kinds, menthol, eucalyptol, and thymol, have been employed with varying success ; of these, thymol appears to be the best, for, while it modifies the odor, it less impairs the antiseptic qualities. The mixture of iodoform and thymol may be in any desired proportion. Lindemann advises the following mixture : Iodoform, 1 part ; balsam of Peru, 3 parts ; and vaseline, 8 parts : or iodoform, 1 part ; balsam of Peru, 3 parts ; alcohol, glycerin, or collodion, 12 parts. So numerous, indeed, are the modes of applying the remedy, that it would be quite impracticable to name them all. Applications. — In' general it may be stated that iodoform is now used in all the wounds, injuries, diseases, requiring the action of an antiseptic. Chancres, ulcers, sloughing and phagedenic ulcers, surgical operations, etc., are especially benefited by its application. It is, above all topical remedies, the most appropriate for gunshot wounds and in- juries (Mundy). As an antiseptic remedy, applied according to the principles of Lasterism, it is no doubt the best remedy thus far pro- posed to prevent decomposition, and to destroy the germs of disease and of putrefaction. The first enthusiasm awakened by it degenerated into an " iodoform-mania," and doubtless much mischief was caused by it ; but, now that the enormous experience in its use can be properly analyzed, more exact rules for its application can be formulated, and its real place in the antiseptic method can be clearly ascertained.

Antagonists and Incompatibles. — Corrosive sublimate is incom- patible with alkalies and their carbonates, lime-water, tartar emetic, nitrate of silver, acetate of lead, albumen, iodide of potassium, soaps, various vegetable infusions, including cinchona. Calomel is incom- patible with the alkalies and alkaline earths and alkaline carbonates? with iron, lead, and copper. It should not be given in the same pre- scription with iodine (forms red iodide), and nitro-muriatic acid should not be prescribed in conjunction with it, lest corrosive sublimate be formed. There is little doubt, also, that calomel is converted into corrosive sublimate by the chlorides of sodium, potassium, and ammo- nium. The acids and acidulous salts are incompatible with hydrargy- rum cum creta. In cases of poisoning by mercurial salts, especially corrosive subli- mate, albumen, white of egg, wheaten flour, milk, etc., may be admin- istered. The white of one egg is considered sufficient for four grains of corrosive sublimate. An excess of albumen may redissolve the com- pound. Emesis should be promptly induced. Synergists. — Depressing medicines, antimony, alkalies, especially alkaline chlorides, etc., promote the physiological activity of mercurials. Physiological Actions. — Metallic mercury in direct contact with the skin or mucous membrane is without action. Swallowed, it is pur- gative by virtue of its weight. If retained in the intestinal canal, it will form soluble combinations, enter the blood, and produce charac- teristic systemic effects. Similarly prolonged contact with the skin will be followed by the constitutional action of the drug. Injected into the veins, it will be arrested in the capillaries, producing the usual phenomena of capillary embolism. Mercury gives off vapors at the ordinary temperatures, which have, in notable instances, caused serious constitutional symptoms. As used in the mechanical arts, by gilders and others, the fumes of mercury cause wasting, ptyalism, necrosis of bones, trembling, impaired intellect, and in women, abortion. With- out producing such obvious effects as ptyalism, mercurial cachexia, eczema, and disease of the bones, obscure nervous phenomena may re- sult. Among these may be enumerated headache, loss of memory, trembling, defects of co-ordination, disorders of sensation, convulsions, and dementia. Mercury is readily absorbed — as a vapor by the pulmonary mucous membrane, when applied to the integument, or when taken into the alimentary canal. It probably exists in the blood as an albuminate. 248 AGENTS INCREASING WASTE. Recent experiments (Wilbouchewitch, Keyes) have shown that mer- cury, as iron, manganese, and other metals, has the power to increase the number of red corpuscles, and to improve the quality of the blood, provided it is exhibited in small quantities, not often repeated. It has long been known (Liegeois) that this result followed the use of cor- rosive chloride in syphilis. Schlesinger has recently gone over the question anew with the same result, but he doubts whether the effects are really tonic. It remains true, however, that any considerable quantity of mercury, administered a sufficient time, will affect the quality and composition of the blood ; the red globules are diminished in number ; the fibrin loses its plasticity ; the proportion of water is increased, and various effete materials, whose nature is unknown, ac- cumulate. Mercury is deposited in all the textures, interferes with the normal nutritive processes, and is found in all the secretions and excretions. A marked degree of anaemia, loss of flesh, muscular weak- ness, intractable ulcerations of the skin, loss of hair, eczema, a foul breath, diarrhoea, the stools being very fetid, are the characteristic symptoms of the action of mercury on the solids and fluids of the body. This metal has a selective action on the lymphatic glandular sys- tem, and notably on the salivary glands and pancreas. Among the earlier symptoms of the action of mercury are an increase of the sali- vary secretion, an alteration of its quality, fetor of the breath, swol- len tongue, soreness of the teeth, a blue or dark slate-colored line along the margin of the teeth, sponginess of the gums, swelling of the parotid, sublingual, and submaxillary glands, aching of the jaws and teeth, with general muscular soreness and aching of the limbs, and some elevation of temperature. To this state are applied the terms acute mercurialismus, ptyalism, in common language, salivation. Mercury certainly stimulates the pancreas ; this gland, like the sali- vary glands, becomes swollen, congested, and pours out an abundant secretion which, however, is not a normal but a pathological secretion. There is little doubt also that mercury increases the action of the in- testinal glandular appendages, and thus acts as a purgative. It not only increases the activity of these glands, but is itself in part ex- creted by them. The products of the increased waste of the tissues caused by mercury are also largely eliminated by the intestinal glands. These actions of mercury should not be regarded as a physiological stimulation of the intestinal glands, in the sense that the foods are stimulant to these organs. The action is pathological, and the prod- ucts of the action are pathological. Mercury, like the metals in general, is excreted by the liver, and manifests a tendency to accumulate in this organ. Like the metals in general (iron, manganese, arsenic, copper, etc.), mercury doubtless acts as a stimulant to the hepatic cells, and increases their products. Just as an altered salivary or pancreatic fluid is produced by the action MERCURY. 249 of mercury, so an altered or pathological bile is the result of the stim- ulation of the hepatic cells by this metal. That its use increases the physiological and normal products of the liver seems an assump- tion hardly warranted by the facts which have now been accumulated. That mercury (pil. hydrarg., calomel, hydrarg. cum creta), in purgative doses, increases the flow of bile into the intestine — is a cholagogue — can not be successfully disputed ; but it is a cholagogue in the sense that croton-oil and the resinous purgatives are : by irritation of the mucous membrane of the duodenum, it causes a reflex contraction of the gall-bladder and hepatic ducts, and an outflow of bile is the result. The presence of alimentary matters in the duodenum suffices to in- crease the production and discharge of bile ; purgatives, for the time being, somewhat more energetically produce the same result. A pur- gative dose of blue-pill, or calomel, may therefore cause bilious evacu- ations, but other purgatives may accomplish the same. Repeated stimulation of the liver by mercurials can only result in the production of an altered bile, and may, indeed, cause the organ to strike work, if too long persisted in. If we add to the cholagogue properties of mer- cury, which it possesses in common with resinous purgatives, the ac- tion on the pancreas and the increased elimination of the products of waste by the intestinal glands, we obtain a satisfactory explana- tion of those powers which have, under the term alterative, been here- tofore ascribed to mercury. Mercury is eliminated by the salivary and the intestinal glands, by the liver, but chiefly by the kidneys. A small portion of the metal escapes by the skin also. The excretion of mercury is hastened and completed by the iodide of potassium. As a result of the changes in the composition of the blood, and of the direct action of the metal on the renal epithelium, albuminuria is one of the symptoms present in cases of mercurialism. Without the use of special means to render it soluble, and despite the use of such means, sometimes mercury remains permanently in the organism. When extremely severe cases of salivation were not uncommon, permanent damage to the osseous structures often occurred, and globules of mercury could be shaken out of the dried bones of such subjects. Happily, nowadays, such cases do not occur. The moderate use of mercury, short of ptyalism, does not appear to affect the human system injuriously. Effects of the Different Preparations. — Hydrargyrum cum creta, calomel, and blue-pill are very similar in action. Calomel, being insoluble, probably escapes solution and combination in the stomach, and is decomposed by the alkaline contents of the small intestine, the oxide of mercury being precipitated. It follows, from this re- action, that the effects of blue-pill and calomel must be similar, and in practice it is found that they correspond closely therapeutically. Salivation more frequently results from the use of blue-pill than the 250 AGENTS INCREASING WASTE. other mercurials ; and calomel is next in point of activity in this respect. The corrosive chloride, the red iodide, and the cyanide, are pow- erful irritant and corrosive poisons. When a poisonous dose of cor- rosive sublimate has been swallowed, the mucous membrane of the mouth has usually, but not invariably, a whitish, glazed appearance, as if it had been washed over with a strong solution of the nitrate of silver. A sense of constriction of the throat and a strong styptic and metallic taste are experienced. The toxic symptoms follow in a few minutes the ingestion of the poison. Usually, violent pain is felt in the abdomen, but this is not invariable. Vomiting follows, and the vomited matters consist at first of the contents of the stomach, and afterward of mucus streaked with blood. There are usually purg- ing, tenesmus, intestinal cramp, and not unfrequently dysenteric dis- charges. These evidences of violent gastro-intestinal irritation are ac- companied by small, weak pulse, coldness of the surface — but some- times by a swollen and flushed face — sighing respiration, syncope, insensibility, or convulsions. If the patient survive a few days, pty- alism may occur. The following are the symptoms of chronic poisoning : abdominal pains ; nausea ; vomiting ; dysenteric diarrhoea ; general weakness, trembling, or paralysis ; ptyalism ; fever ; emaciation, etc. There sometimes occurs a blue line along the margin of the teeth, not unlike that produced by lead. Suppression of urine is a not infrequent symptom in acute poison- ing, and albuminuria is very often present in cases of chronic mer- curialismus. Therapy. — The acute glandular affections of throat and neck — tonsillitis, parotitis, inflammation of the submaxillary and sublingual glands — are often speedily removed by mercurial preparations. The one twentieth of a grain of calomel, the one fifth of mercury with chalk, may be given every two hours, or one minim of the follow- ing solution may be administered at the same interval : $ Hydrarg. chlor. corrosiv., gr. j ; aquae, 3 j. M. Sig. : Dose, Tq, j. Chronic af- fections of these organs are not benefited by these remedies, and the so-called scrofulous diseases of the cervical glands are made worse by them. Corrosive sublimate is an effective remedy in gastric ulcer. The thirtieth to the sixtieth of a grain, three times a day before meals, is a proper quantity and occasion for this purpose. Certain kinds of vom- iting are quickly cured by small doses of calomel. The vomiting of children, caused by indigestible food or by constipation, or by these causes combined, is often speedily relieved by one-twelfth-of-a-grain doses of calomel every half -hour or hour, dropped on the tongue. This remedy is the more efficacious when such vomiting is accompanied by MERCURY. 251 great heat of head, restlessness, and fever. The vomiting of cholera infantum is often stopped by the same means. It has long been held that mercurials are specially indicated in that catarrhal state of the intestinal mucous membrane and of the hepatic duct, manifested by nausea, anorexia, tympanites, whitish or clay-col- ored stools, and jaundice. The use of mercury in these cases is predi r cated on its supposed power to promote the flow of bile. It is true, no doubt, that calomel and blue-pill will remove these symptoms, but such mild salines as phosphate of soda, sulphate of magnesia, tartrate of soda and potassa, etc., will usually succeed quite as well and with- out detriment to the patient. The diarrhoea and dysentery of infants (ileo-colitis) is frequently treated by minute doses of calomel or hy- drargyrum cum creta. When there are much straining and bloody mucus, it is said that small doses of corrosive chloride prove very effective, but the author is convinced that mercurials are much abused in these affections. Children are quickly poisoned by mercurials, al- though they are not easily salivated. The spinach-colored stools which so frequently occur in the summer complaint of children, and which are, by ignorant practitioners, supposed to be produced by the mercury administered, really belong to cases of ileo-colitis, and may, by their persistence and profuseness, signify an increased irritation of the intestinal mucous membrane due to the remedies given. While the author believes that other medicines are more useful than mercury in the ileo-colitis of children, he is convinced of the utility of minute doses of calomel (one twentieth to one twelfth of a grain every half- hour) when there is much irritability of the stomach. Mercurials are contraindicated in the diarrhoea and dysentery of adults, as a rule. It was formerly an article of faith to hold that mercury was a sov- ereign remedy in hepatic disorders. The state known as biliousness, characterized by a yellowish-coated tongue, yellow conjunctivae, muddy skin, nausea, constipation, may be removed by a mercurial purge when these symptoms are due to catarrh of the duodenum, excesses of the table, sudden checking of the perspiration, etc. The blue-pill, or mercury with chalk, or calomel, succeeds in these cases by removing offending substances from the intestinal canal, by relieving a catarrh- al state of the mucous membrane, or by causing elimination of waste products by the intestinal glandular apparatus. Less objectionable agents may be employed with equal success. The experience of the India medical officers has shown conclusively that mercurials are harmful in acute hepatitis, hepatic abscess, jaundice from gall-stones, acute yelloio atrophy, etc. As these affections are very rife in India, an experience which has led to such conclusions should be heeded. There is no evidence to show that mercurials ren- der the least service in cirrhosis. Calomel is a very efficient purgative. It will be retained when 252 AGENTS INCREASING WASTE. other purgatives are rejected by the stomach ; it is free from taste, and may therefore be given easily to children. When it operates, nausea and tormina may be experienced. One grain of calomel at night will act in the morning, and not unfrequently a half-grain will give satisfactory results. A full purgative dose of calomel (five grains) is an excellent vermifuge for the lumbricoid worms. It may be given with santonine. At the onset of acute febrile diseases, calomel is a useful purgative ; it hastens waste, and causes the elimination of the products by the intestine. Mercurials were formerly much esteemed in the treatment of acute inflammation, especially of serous membranes. As calomel — the mer- curial preparation usually employed — was combined with opium, it was not known to which remedy the good results were due, but the mer- curial was considered to have the larger share of merit. It is now admitted that opium was the effective agent. An apparent exception to this statement exists in the case of iritis, a disease in which the good effects of mercury are most conspicuous ; but iritis, probably, is always of syphilitic origin, and, in syphilitic inflammation of serous membranes, it is not disputed that mercurials are extremely efficacious. In these days, however, although opium is considered indispensable in peritonitis, pleuritis, pericarditis, etc., mercury is no longer combined with it. No longer is it considered necessary to " touch the gums " in order to cure a serous inflammation, and only the most prejudiced and benighted practitioners insist in the use of mercurials in these in- flammatory affections. Large doses of calomel — five grains every four hours — are said to be very efficacious in true croup or membranous laryngitis. It is claimed that it allays spasm and checks the formation of the false membrane. The author is skeptical in regard to the utility of calomel in this affection. There is, however, no doubt as to the value of the yellow subsulphate (turpeth mineral) as an emetic in this disease. If given early, it is the doubtful statement of Dr. Fordyce Barker, of New York, that a fatal result will most certainly be averted. From two to four grains of the subsulphate may be given as an emetic for a child with croup. Serious results might be produced by this dose if emesis did not so promptly follow. The powder comes up with the contents of the stomach, in from five to fifteen minutes after being swallowed. But little depression follows the emesis produced by turpeth mineral, in which respect it has a decided advantage over sulphate of cop- per, tartar - emetic, and even ipecacuanha. As it is insoluble, this remedy should be rubbed up with sugar and placed on the base of the tongue. Corrosive sublimate has lately been used with very distinct advan- tage in the treatment of diphtheria. Its remarkable germicide prop- erty is the motive for its employment, and clinical experience strongly MERCURY. 253 supports the results of experiment. The dose administered in the treatment of diphtheria will range, according to the age of the sub- ject, from y^o grain to -^ grain every four or six hours. Liebermeister, following the lead of Traube, Wunderlich, and others, has obtained surprising results from the use of calomel in typhoid fever. By our German confreres this treatment is called the specific treatment of abdominal typhus. It consists in the administration of ten grains of calomel in a single dose the first day, and eight grains a day for three or four days thereafter. It is a curious fact that these large doses of calomel have an antipyretic effect. According to the statis- tics of Liebermeister, the " specific " calomel treatment shortens the duration and lessens the mortality from typhoid fever, as compared with the non-specific, expectant, or other plans of medication. Calomel is one of the numerous remedies used in the treatment of cholera Asiatica. Two methods are pursued : large doses at consider- able intervals ; small doses frequently repeated. The latter method is nowadays much more usually practiced. In consists in giving every fifteen minutes, half -hour, or hour, the one sixth, one half, or one grain of calomel, combined with opium, chalk, piperine, etc. The author, who has had considerable experience in the treatment of cholera, can not express any degree of confidence in the efficacy of this treatment. Large doses (a scruple to a drachm) sometimes appear to arrest vomit- ing when other means fail, but there is danger of excessive ptyalism when reaction sets in. The most important application of mercury therapeutically is in the treatment of syphilis. It may be regarded as a specific in this dis- ease. The reaction which set in against its use a few years ago has certainly led to important modifications in the mode and quantity in which mercury should be given ; but the fact has been conclusively established that mercury in a certain sense is antidotal to syphilis. As mercury arrests the proliferation of the syphilitic virus in the blood, this agent should be used with the earliest manifestations of the specific character of the infecting sore. Mercury is not indicated in chancroid, or non-infecting chancre, and should not be used. If the chancre have the characteristic quality of the infecting sore, small doses of one of the mercurial preparations should be begun and continued steadily until all induration has disappeared. The important point is, not to induce ptyalism. It is now conceded that the danger of a relapse will be very much lessened by continuing the mercurial treatment for some time — for several months — after local manifestations have ceased. The ill effects of a mercurial course may be prevented by the use of small doses, by careful attention to hygiene, and by lessening the dose, or discontinuing the remedy entirely, whenever soreness of the jaws can be developed by smartly closing the teeth. By the adoption of these precautions, a mercurial course may be continued without im- 254 AGENTS INCREASING WASTE. portant interruptions until the period of incubation has entirely passed, and through the so-called secondary or constitutional stage. Various methods are resorted to for the introduction of mercury into the organism : 1. Inunction. — Before practicing inunction, the patient should take a warm bath, or, at least, wash the part to be operated on with soap and water. From fifteen to thirty grains of mercurial ointment is the quantity required for each inunction. The oleate of mercury in pro- portion of fifteen to thirty per cent in the solution may be substituted for the ointment, but the oleate is to be applied with a brush, and not be rubbed in. Sigmund, the great advocate for the inunction method, has prescribed certain rules, which should be followed. The ointment should be rubbed in with moderate friction by the palm of the hand : on the first day on the legs ; on the second day on the thighs ; on the third day on the abdomen and sides of the chest ; on the fourth day on the back ; on the fifth day on the arms. Mercurial inunctions are not borne equally well by all patients. Some are easily salivated, and others suffer from eczema or erythema. Moreover, the inunction treat- ment is filthy and troublesome, and it should, therefore, be restricted to those cases in which mercurials are badly borne by the stomach. 2. Fumigation. — Various mercurial preparations may be used — the sulphuret, the iodide — but calomel is the best. The apparatus consists of a spirit-lamp, a plate to hold the calomel, surrounded by a shallow vessel containing water, a blanket large enough to cover the patient and the apparatus. The calomel is volatilized by the heat of the lamp, and is deposited, together with the vapor of water, on the skin of the patient. About fifteen minutes is the time required for the bath, and the quantity of calomel used ranges from eight to fifteen grains. The method of fumigation is especially adapted to cases of the con- stitutional, or secondary, and to the tertiary, with ulcerations, when the state of the patient is such as to forbid the internal administration of mercurials. 3. Hypodermatic Method. — This consists in the introduction under the skin of corrosive chloride, or albuminate of mercury. 3 Hydrarg. chlor. cor., gr. j ; glycerini, 3 j ; aquse destil., 3 ]*• M. Sig. : Ten min- ims a dose once a day. This method is cleanly, quick in results, and more successful than any other in preventing relapses. The peptonate of mercury, as advocated by Bamberger, has been much employed lately for the treatment of syphilis by the subcutane- ous method ; but the albuminate alone, without pepsin, is both more effective and less likely to set up local inflammation. The following formula for the preparation of albuminate of mercury, recommended by Gourgues, is probably the best now available for this purpose : Bichloride of mercury, gr. xv ; distilled water, 3 v. To this solution is added five drachms of white of egg, and, after thorough shaking, MERCURY. 255 the mixture is incorporated with the following : Chloride of sodium (common salt), gr. xxx ; distilled water, f 3 ij. This mixture is then well agitated, and afterward filtered, after which sufficient distilled water is added to make the solution up to four fluid ounces. The dose of this solution for hypodermatic injection is from ttt, xv — 3 ss. When finished, the solution is not clear, but rather semi-transparent ; but it remains longer and better in solution than most of these preparations. The peptonate of mercury is not only variable in composition, but easily undergoes change, and is liable to produce violent local irrita- tion. The albuminate prepared as above suggested is readily admin- istered, is not painful, and is rarely followed by unpleasant accidents at the site of the injection. As regards the results of the administra- tion on the progress of the disease, they are remarkable (Gourgues). According to Martineau, the hypodermatic mercurial treatment exer- cises on syphilis in its various manifestations an action much more effective, more energetic, and more rapid, than any other method hith- erto proposed. The subcutaneous areolar tissue of the back is the best place for the injections. The number of them and the quantity of fluid used will depend on the stage of the disease, the severity of the manifestations, and the condition of the patient. Besides the preparations above mentioned, other solutions of corro- sive chloride have been proposed. Matthes recommends the follow- ing : Bichloride of mercury, gr. xv ; chloride of sodium, gr. xxx ; dis- tilled water, f f iij. Make a solution. Matthes had observed the action of this during two years at Auspitz's polyclinic. The usual dose was a Pravaz syringeful — fifteen to twenty minims — every two days. No irritation is produced beyond some tumefaction, and, in general, twenty to thirty injections sufficed to effect a cure. Recently, Liebreich has brought forward the formamide of mer- cury as the most suitable preparation for the hypodermatic method. It is neutral in reaction, readily soluble in water, and does not coagu- late albumen. 4. Internal. — This method, in the nature of things, must be most frequently resorted to. Various mercurial preparations are used by different syphilographers. The Ricord school prefer the green iodide ; Sigmund, mercurial-ointment inunctions ; Foerster, the yellow iodide ; Berkeley Hill, the red iodide ; Tilbury Fox, the cyanide ; Bumstead advises mercurial pill, the green iodide, the bichloride, according to circumstances, but his preference is for the use of calomel by fumi- gation. That preparation of mercury is to be preferred which best agrees with the patient, is the rule. The indications for the use of iodine preparations have already been stated, but it may be useful, now, to place in juxtaposition the com- parative utility of mercury and iodine : mercury for the primary in- fecting sore ; mercury for the affections of the skin, especially macular 256 AGENTS INCREASING WASTE. and papular exanthemata ; iodine for the tertiary symptoms : gummata ; tubercular syphilides ; serpiginous ulcers ; affections of the bones and periosteum, and nervous diseases. Hydrargyrum cum creta is usually preferred for the treatment of congenital syphilis. Mr. Marshall recommends the twenty-per-cent ointment (the size of a pea) of the oleate of mercury, to be placed in the axilla night and morning for five or six days. Local Uses of Mercurials. — Recent experimental investigations on the action and comparative germicide properties of the various anti- septics have shown the superiority of corrosive sublimate over all others ; hence it has come to be largely used in the dressing of wounds, and as a local application to specific ulcerations, etc. The acid nitrate of mercury is one of the best caustics for the destruction of chancroid. It should be applied with a glass rod after the surface of the sore has been well cleansed. It is now conceded that destruction of an infecting chancre does not prevent systemic infection. Syphilitic warts and vegetations on the genitals are amenable to the same treat- ment. Erosions and ulcerated indurations are best treated by " black - wash " (calomel, eight grains — lime-water, one ounce), or " yellow-wash " (one grain of corrosive sublimate to an ounce or two of lime-water). The surface of the sore may be kept wet with these lotions. Ricord's treatment of condylomata consists in washing them with a solution of chlorinated soda, and then dusting them with calomel. Mercurial applications are of very great service in cutaneous affections of syphilitic origin. A drachm of calomel to an ounce of lard makes an ointment which is very serviceable in herpes, psoriasis, and pruritus of the vulva and anus. Ringer speaks of calomel-ointment in terms of great praise in various itching affections, especially of the anus and perinseum. In acne, lotions containing corrosive sublimate, and oint- ments of green and red iodide, are much employed : $ Hydrarg. chlor. cor., 3] ; glycerini, 1 ss ; spts. vini rect., f vij ; spts. rosmar., 3 iv. M. For acne and pityriasis of the scalp : fy Hydrarg. iod. virid., gr. x ; adipis, § j. M. $ Hydrarg. iod. rubri, gr. v ; adipis, § j. M. For acne indurata. The following is Startin's lotion of corrosive sublimate for syphilitic eruptions : J£ Hydrarg. chlor. cor., gr. iv ; acid, nitric, dil., 3 j ; acid, hydrocyan. dil., 3 j ; glycerini, 3 ij ; aquae, § viij. M. F 'or pityriasis, chloasma, etc. Lotions of corrosive sublimate are much employed in the treatment of parasitic skin-affections. The stronger ones must be used with cau- tion. It is rarely necessary to use a lotion stronger than two grains to the ounce. The following is an excellent formula of Tilbury Fox : I£ Hydrarg. chlor. cor., grs. iv ; alcohol, 3 vj ; ammonias muriat., 3 ss ; aquae rosae, q. s. ad | vj. M. For scabies, ptheiriasis, and tinea versi- color. A scruple of corrosive sublimate to the ounce of simple oint- MERCURY. 257 ment is an effective application in favus and tinea tonsurans, when used in the early stages of these affections. Calomel finely levigated and dusted over the membrane by means of a camel's-hair brush is an excellent local application in phlyctenidar ophthalmia. Eczema of the margin of the eyelids is quickly cured by rubbing in every night, after detaching the scales, a small quantity of the brown citrine-ointment. Chronic inflammation of the external auditory meatus is cured by the same application, viz ., by allowing a small quantity of the brown citrine-ointment to remain in contact with the integument. Mr. Marshall strongly recommends the oleates in parasitic skin-dis- eases. He employs a five-per-cent solution of oleate of mercury in oleic acid, adding an eighth part of ether. This is applied by means of a camel's-hair brush. It is used in sycosis, tinea, and chloasma, porrigo, pruritus ani, and pruritus pudendi. The oleates are extremely serviceable remedies for the local treatment of syphilitic induration, but they are not advisable when ulceration exists. The oleate of mercury and morphia (obtained by the addition of the alkaloid morphia) is an elegant and efficient application in super- ficial inflammations, especially of joints of the rheumatic and arthritic varieties. Inflammatory indurations, left after the subsidence of acute trouble, are removed by the same combination. For application to these purposes Mr. Marshall employs a five-per-cent, ten-per-cent, and twenty-per-cent solution of oleate of mercury in oleic acid. To every drachm of such solution he adds one grain of morphia. Mr. C. Bader, the eminent ophthalmologist of London, advises the following ointment in conjunctivitis: P> Hydrargyri oxidi rubri, gr. x ; atropiae sulph., gr. j ; vaselin., 3]*. M. Dr. Seely, of Cincin- nati, strongly urges the use of an ointment of the yellow oxide, eight or ten grains to the ounce of vaseline. He directs that the yellow oxide be triturated to the utmost degree of fineness, and then thor- oughly incorporated with the vaseline, the result being a bright-yellow ointment. A portion of this is taken on a probe, the lid lifted up, and the whole is wiped off on the mucous membrane. For pruritus of the vidva, the following lotion is recommended : Hydrarg. chlor. cor., one part ; alum, 20 parts ; starch, 100 parts ; and water, 2,500 parts. The official ointment of the red iodide of mercury is an effective application in simple hypertrophy of the thyroid gland, and an enlarged spleen, or ague-cake. A bit of ointment, the size of a large pea, is thoroughly rubbed in over the affected organ, the sun's rays falling on the part if practicable, or the friction may be carried on before a bright fire, or without. As soon as the skin becomes sore the applications are suspended until it recovers, when they may be re- sumed. The applications should be made daily. For that parasitic affection of the skin, pityriasis, there is no lotion 17 258 AGENTS INCREASING WASTE. so effective as a strong solution of corrosive sublimate— 3 j — 3 j — § iv of rose-water. It need hardly be observed that these strong solutions require very careful handling. Less than necessary will fail, and application to an abraded surface will induce toxic symp- toms. Aurum. — Gold. Or, Fr. ; Gold, Ger. Auri Chloridum. — Chloride of gold. (Not official.) Needle- shaped prisms of a beautiful yellow color, deliquescent, freely soluble in water. Dose, gr. ■&— gr. T \. Auri et Sodii Chloridum. — Chloride of gold and sodium. An or- ange-colored salt, crystallizing in four-sided prisms, soluble in water. Dose, gr. -g^— gr. tV Antagonists and Incompatibles. — Eggs, albumen, milk, flour, are chemical antidotes. The contents of the stomach should, of course, be evacuated. The principles of treatment are the same as for poison- ing by corrosive sublimate. Synergists. — The salts of mercury, especially the corrosive chloride, are very similar in action to the chlorides of gold, and are therefore synergistic. Physiological Action. — The chloride of gold is a caustic in its local action. In toxic dose it excites violent gastro-enteritis, accom- panied by such nervous phenomena as cramps, convulsive trembling, insomnia, priapism, insensibility, etc. In small medicinal doses these auric preparations promote the appetite and the digestive capacity. If long continued, especially if the dose be a full medicinal one, epigastric pain and distress are excited, nausea is induced, and loss of appetite follows. Constipation is usually produced by the preparations of gold, and this, notwithstanding an increased secretion of the intestinal glandular apparatus is one of the results of their administration. These preparations do not probably entirely enter the blood from the stomach, but part passes to the intestinal canal, is there decomposed, and is absorbed as oxide in combination with albumen. This is, how- ever, conjectural. They are readily soluble and are very diffusible substances. What particular influence they exert on the composition and function of the blood is at present quite unknown. A form of fever, known as . auric fever, is caused by their prolonged adminis- tration. This fever is accompanied by profuse sweats, a very abundant flow of urine, and increased salivary secretion. The salivation caused by the preparations of gold differs from the mercurial in that there is no tenderness nor ulceration of the gums. Peculiar effects on the mental state are produced by the adminis- tration of the auric preparations. The functions of the mind become more active, and even excited, and a state of cheerfulness is induced. In men, marked aphrodisiac effects are produced, and the erections are GOLD. 259 often painful ; in women, increased venereal desires and augmentation of the menstrual flow are observed. The elimination of the auric preparations takes place by the liver, the intestinal canal, but chiefly by the kidneys. The urine assumes a bright-yellow color. Prolonged administration of medicinal doses induces epigastric heat and oppression, headache, dryness of the throat and mouth, gastro- intestinal irritation, fever. Therapy. — The chloride of gold and sodium in small doses (fa grain), three times a day, will relieve nervous dyspepsia. A red and glazed tongue, epigastric pain, increased by talcing food, and a tend- ency to relaxation of the bowels after eating, are indications for the use of this salt. Catarrh of the duodenum, catarrh of the bile-ducts, and jaundice dependent thereon, are symptoms which may usually be removed by the salts of gold. These preparations are employed chiefly in the treatment of syphilis, secondary and tertiary. They are indicated in the same cases in which corrosive sublimate is found effective. According to the author's ex- perience, they are especially adapted to old cases in which a protracted mercurial course and the large use of the iodide of potassium have failed to remove long-standing tertiary symptoms. He has found them very serviceable in recurring syphilitic tdcerations of the throat, syphi- litic ozwna, syphiloma of bones, syphilitic phthisis, etc. Amenorrhcea, dependent on torpor of the ovaries, may be removed by the persistent use of auric preparations. Chronic metritis, with scanty menstruation, is often remarkably benefited by them. Sterility, dependent on these states, or due to coldness, is more certainly cured by these agents than by any other merely medicinal means. It is said by Martini that the tendency to habitual abortion may be averted by the use of chloride of gold. This authority has also found that dropsy of the ovary may be sometimes cured by the same agent. Decline of the sexual power in man may be prevented by the use of gold salts, and the following are symptoms which may be removed sometimes by them : diurnal seminal losses, loeak and inefficient erec- tions, inability for the sexual congress, due to irritability of the sexual organs. They increase the frequency of the nocturnal losses in those who are suffering from plethora of these organs. Cases that are bene- fited by the bromide of potassium are increased by the chloride of gold, and vice versa. The author calls especial attention to the use of the salts of gold in chronic BrigMs disease, granular and fibroid kidney, and the so-called depurative disease. He has observed remarkable improvement to fol- low the persistent use of the chlorides of gold in these affections. They are best given in pill-form, and in small doses, fa — fa of a grain three times a day. It need hardly be mentioned that these preparations are 260 AGENTS INCREASING WASTE. not adapted to the acute forms of Bright's disease. Further experi- ence confirms me in the view above expressed in regard to the value of chloride of gold and sodium in the treatment of chronic albuminu- ria. Not only, in my own hands, but in cases thus treated by others, this remedy has proved to be a very valuable addition to our resources in this hitherto intractable malady. Excellent results are obtained from the use of these auric prepara- tions in certain forms of mental disorder : e. g., melancholia, hypo- chondria, and allied mental states, accompanied by depression. Ver- tigo and vertiginous sensations, when due to stomach-disorders, are often removed by minute doses of the chlorides of gold, but plethora and increased intracranial blood-pressure contraindicate their use ; on the other hand, they have a high degree of utility when there is pres- ent the condition of cerebral anaemia. The author has been favored with a private communication from Dr. Bauduy of St. Louis, in which this experienced and able physician expresses his confidence in the value of this remedy in the treatment of hypochondriasis and melancholia, based on much personal experience. The modern expe- rience is therefore in harmony with the observations of the refined and learned author of the "Anatomy of Melancholy." Authorities referred to : Gubler, Dr. Adolph.

An insoluble chloride of silver is the result of the decomposition. The following mineral acids and their salts are chemically incompatible : Sulphuric, muriatic, tartaric, and sul- phurous. Alkalies and their carbonates, astringent infusions, and lime-water are incompatible. In cases of poisoning by nitrate of silver, common salt is the appropriate antidote. This should be given in solution very freely, to act as an emetic as well as chemical antidote. Therapeutically the salts of silver are antagonized by all those agents which promote constructive metamorphosis. Synergists. — All agents promoting waste, as mercury, iodides, etc., favor the action, therapeutically, of nitrate of silver. Physiological Actions. — Nitrate of silver acts chemically on the tissue to which it is applied. It combines with the albumen, and ex- cites a superficial inflammation, producing in some subjects vesication, in all a whitish eschar. It is, therefore, an escharotic, but of very limited activity. The white eschar produced by it, subsequently — under the influence of light — becomes brownish-black. Nitrate of silver has a strong metallic, styptic taste. A strong solu- tion, brushed over the mucous membrane, whitens it. In the stomach, the salts of silver produce a sense of warmth at the epigastrium, and, in large (toxic) doses, excite a violent gastro-enteritis. Meeting in the stomach soluble chlorides, undoubtedly the insoluble chloride of silver is formed, but a portion of the salt, probably, at once enters into com- bination with albumen and peptones. That the action of nitrate of silver, when swallowed, is not that of the chloride, has been experi- mentally shown ; hence the conversion of the nitrate salt into chloride does not suflice to explain the effects which ensue. Increased secre- tion from the intestinal glandular apparatus is produced by the silver salts, and the alvine dejections are softer and more frequent. Long- continued use of these agents will cause gastro-intestinal catarrh. The salts of silver most probably enter the blood as albuminates and peptonates. They effect very important changes in the blood, which becomes darker and more fluid, the red corpuscles paler and altered in outline, the haemoglobin converted into hsematin. A slight lowering of the temperature is a result of these changes in the com- position of the blood. Various tissues of the body undergo patho- logical alterations. The epithelium of the intestinal mucous membrane, of the kidneys and liver, becomes swollen and cloudy, and sometimes fatty. The amount of bile is increased, and albumen frequently ap- pears in the urine. The nutrition of the body is impaired and a pro- gressive diminution in weight and strength takes place. The venous system is found in a state of stasis ; transudations take place, the 262 AGENTS INCREASING WASTE. action of the heart is rapid and irregular, and the respiration is embar- rassed. The nervous system participates in the general impairment of structure ; tetanic convulsions, paralysis, and insensibility, ensue. The paralysis is not due to alterations in the muscular system — for the muscles preserve their irritability — but is centric in origin. It is true the muscles, in poisoning by silver, become granular and their striae obliterated, but their contractility is not destroyed. Only a minute part of the silver administered is eliminated by the kidneys ; most of it escapes by the liver and the intestinal glands ; but a portion remains permanently deposited in the tissues if its adminis- tration has been protracted. Rarely is it safe to continue the use of the preparations of silver longer than six weeks, and occasional purga- tives should be given to promote elimination. An olive, slate-colored, or grayish-brown discoloration of the various tissues of the body results from a deposition of silver. This is usually first seen at the margin of the teeth or on the inside of the lips and cheeks, and is an indica- tion that the system is becoming saturated. I find in Sieveking, " On Epilepsy," the following instructive instance of argyria : " The pa- tient, a man aged sixty, became epileptic in March, 1856, and was treated with nitrate of silver almost from the commencement ; for nine months he took a daily pill containing six grains, so that, during that time, he swallowed nearly three and a half ounces. Toward the end of July the skin began to be discolored, but, in spite of gastric symptoms, the remedy was persevered in. In 1857 hsematemesis and other symptoms of gastric ulceration supervened, while the severity of the epilepsy had abated, and, having in the mean time come to England, he was admitted to the German Hospital, where he soon died. The special interest attaching to the autopsy is connected with the extent to which the silver had been deposited in the tissues. The parts in the face which had exhibited the greatest intensity of dis- coloration, owing to their containing more blood, now presented a tint uniform with the rest. In the brain the choroid plexuses presented a uniform grayish-blue tint. The lungs were tuberculous and pneu- monic, the heart hypertrophic. The stomach contained a large quan- tity of acid, brown liquid streaked with blood, and at the upper part of the posterior wall was a large ulcer, at the base of which was an orifice blocked up by the adherent pancreas. The mucous membrane of the duodenum and jejunum was dotted over with many small black granules, most closely aggregated along the folds. In the ileum these spots became more and more scanty. . . . The spleen was small, its veins had an ashen hue, which was due to a finely-granular precipitate upon their coats. The liver was small, congested, and fatty ; the small branches of the vena portse and of the hepatic veins presented the same precipitate of silver throughout, but the capillaries were free from SILVER. 263 it. Fine sections of the hepatic tissue showed numerous black dots, each of which occupied the center of an acinus, corresponding to the point of exit of a central vein, and the color was produced by a black margin surrounding the caliber of the artery. The largest argentine deposit was in the kidneys. . . . The pyramids all exhibited a dark- gray color, which was deepest, and all but black, near the papillae. The tubules in these parts were entirely invested with a dense precipi- tate. . . . Parts of the skin taken from the temporal, axillary, and digital regions, were examined. Transverse sections showed a pale, purplish streak immediately underneath the rete Malpighii, following the undulations of the cutis. . . . The glandular epithelium uniformly presented fatty degeneration." A persistent and long-continued use of the iodide of potassium and of the hyposulphite of soda has, in a few fortunate instances, caused the absorption and excretion of the silver deposits. The action of these systemic remedies for the discoloration may be aided by baths of the hyposulphites and by the cautious use of lotions containing the cyanide of potassium, which possess a decided solvent power over the silver deposits. Theeapt. — The oxide and the nitrate of silver are extremely ser- viceable remedies in the so-called nervous dyspepsia, and in chronic gastric catarrh. They are indicated in the following state of things : Pain after taking food, lasting for an hour or more (gastralgia), the digestion, although slow, being good ; burning pain, with pyrosis, com- ing on after the completion of the stage of stomach digestion ; eructa- tions of food, with sour and acrid matters — the first being a gastralgia, and the other states being caused by gastric catarrh, and consequent fermentation of the starch, sugar, and fats. $ Argenti oxidi, grs. v ; ext. hyoscyami, grs. v. M. Ft. pil. no. x. Sig. : One three times a day before meals. In chronic gastric catarrh, Frerichs recommends the following formula : $ Argenti nitrat., grs. xv ; aq. destil., q. s. ; ext. belladonnse, grs. x ; ol. caryophylli, gtt. x ; rad. gentian pulv., ext. gentianae, aa q. s. ut ft. pil. no. lx. Sig. : One pill three times a day. When there is much pain present, Wilson Fox highly commends the combination of nitrate of silver and opium in chronic gastric catarrh, but, as constipation so frequently attends this state, belladonna or hyoscyamus is usually to be preferred. Notwithstanding the strong opinion which Brinton has given adversely to the use of the salts of silver in nicer of the stomach, the author agrees with Fox that these agents are, in this affection, next in value to bismuth. The oxide, or the nitrate, may be given in pill-form, as above, or the nitrate in solu- tion. In these stomach-affections, as a rule, the oxide of silver — being free from the causticity of the nitrate — is preferable. In jaundice dependent on catarrh of the biliary ducts, especially when there are present considerable pain and stomach-disorder, the 264 AGENTS INCREASING WASTE. salts of silver not only give relief to some of the more distressing symptoms, but assist materially in restoring the functional activity of the liver. As respects these hepatic disorders, silver has an action simi- lar to arsenic, manganese, mercury, and some other mineral remedies. Frequently nitrate of silver is remarkably beneficial in cholera in- fantum, after the acuter symptoms have subsided. The following is an excellent formula for a child a year old : t> Argenti nitrat., gr. j ; acid, nitric, dil., ttl viij ; tinct. opii deod., Til viij ; mucil. acacise, § ss ; syrup, simplicis, 3 ss ; aquae cinnamomi, ^ j. M. Sig. : A teaspoonful every three, four, or six hours. The nitrate of silver is also an efficient remedy in that form of diarrhoea in children in which the stools are white, pasty, and offensive, and the urine is high-colored and acrid. In dysentery, both of children and adults, after the acute symptoms have ceased, and in chronic dysentery, the nitrate of silver is a most efficient remedy. In some epidemics of acute dysentery, when the constitutional condition is one of depression, it is equally effective. In these mala- dies it is better to prescribe the nitrate in pill-form (gr. \ — gr. j) com- bined with opium. With the stomach administration of the nitrate may be conjoined its local application to the rectal mucous membrane, and even in favorable instances to the descending colon. In using nitrate of silver by enema, the application, to be effective, should be made through a flexible tube passed cautiously to the sigmoid flexure or beyond. The bowel, previous to the introduction of the silver solu- tion, should be as thoroughly washed out as possible by tepid water. From ten to twenty grains of the nitrate of silver, to a pint of water, is a suitable proportion for an enema. Obstinate dysenteric discharges, either alone or mixed with healthy- formed faeces, are not unfrequently caused by an ulcer of the rectum. The most effective treatment for such an ulcer consists in the applica- tion to it, through a suitable speculum, of the solid stick of nitrate of silver. The author's experience justifies him in asserting that the most effective remedy for the diarrhoea of phthisis is nitrate of silver com- bined with opium. When the diarrhoea of typhoid fever resists bis- muth, Hope's mixture, and laudanum enemata, a satisfactory result may often be obtained by nitrate of silver, as follows : 3 Argenti nitrat., grs. iij; pulv. opii, pulv. ipecac, aa grs. vj. M. Ft. pil. no. xij. Sig. : One every four or six hours. The nitrate of silver is one of the numerous remedies which have been used in the treatment of cholera. Formerly nitrate of silver was much employed in the treatment of epilepsy, but it has justly fallen into disuse, for, besides the danger of tinting the skin, it is not as effective as much less objectionable reme- dies. Iodide of silver has proved very useful in the treatment of whooping-cough, in the hands of Dr. Bell, of Glasgow. He gives one eighth of a grain. Since proposed by Wunderlich, this agent has been SILVER. 265 fairly tested in the treatment of posterior spinal sclerosis (progressive locomotor ataxia), and seems to have some influence in retarding the progress of the disease. Local Uses. — Nitrate of silver is largely used as an external appli- cation. A case has recently been reported in which argyriasis was produced by the free application of this salt to the fauces, hence some care should be exercised in applying it to the mucous membranes. For external use, the cylinder and solutions of various strengths are em- ployed. The " mitigated " stick is used chiefly by ophthalmologists. The most satisfactory solution for local application to the skin is ob- tained by dissolving the salt in nitrous ether (gr. v — 3 j — § j of ether). This solution acts more energetically than the aqueous solution, and will readily vesicate. Solutions of nitrate of silver are much less frequently applied than formerly to inflamed tonsils, diphtheritic affections of fauces, acute laryngeal troubles, oedema of the glottis, etc. In the incipiency of tonsillitis, a strong solution (3j — 3 j — | j) may sometimes avert the attack, but if the inflammation be well established the irritant action of the caustic increases the morbid process. The most enlightened modern authorities (Oertel) condemn the use of caustics in diphtheria ; forcible detachment of the exudation only increases the chances of systemic infection, and injury done to the surrounding healthy mu- cous membrane invites the extension of the false membrane. A suffi- cient quantity of silver solution, to be effective, can not be applied to the larynx, nor even to the aryteno-epiglottidean folds, without the aid of the mirror, and this manipulation is hardly available when a state of acute inflammation exists. Follicular pharyngitis is one of the affections which can be successfully treated by systematic local applications of silver solution. Catarrh and idceration of the poste- rior nares may be cured by persistent use of the same remedy, the application being made by a suitable sponge probang, or brush, passed behind the veil of the palate. The appropriate strength for these pur- poses will depend, in part, on habit (grs. v — 3j — J j). Very weak solution of nitrate of silver (gr. j — \ j) is sometimes used by the spray-douche (glass tube) in chronic inflammation of the pharynx, larynx, and trachea. Besides the ineffectiveness of this method, it is objectionable because the silver spray stains the face and clothing of the patient, unless a shield is very carefully used. To ulcers of the tonsils, tongue, syphilitic and otherwise, the solid nitrate is often used. It is a very painful application, and possesses but slight, if any, advan- tages over carbolic acid, which is anesthetic after the first contact. A strong solution of nitrate of silver, especially in nitrous ether, is a most efficient application to check inflammation in superficial parts, e. g., boils, felon (paronychia), thecal abscess, orchitis, synovitis, etc. It is essential to the success of this treatment that the application be 266 AGENTS INCREASING WASTE. made early. According to the method of Mr. Furneaux Jordan, it is better to make these applications to the adjacent "vascular territory," than to the inflamed part directly. To illustrate : In the case of orchitis, instead of painting the silver solution over the testicle, it is better to apply it along the groin and inner face of the thigh, over the course of the great vessels. Mr. Higginbottom, who is the author of this method of treatment, says that " we have no therapeutic agent so safe, powerful, or effica- cious, as the nitrate of silver in subduing external inflammation when properly applied. It has been invariably successful in my hands for nearly the last forty years." Such unstinted praise from so eminent an authority deserves our most respectful consideration. As the proper application of the remedy is so important, it were better to follow literally the method of Mr. Higginbottom : " The affected part should be well washed with soap and water, then with water alone, to remove every particle of soap, as the soap would decompose the nitrate of silver ; then to be wiped dry with a soft towel. The con- centrated solution of four scruples of the nitrate of silver to four drachms of distilled water is then to be applied two or three times on the inflamed surface and beyond it, on the healthy skin, to the extent of two or three inches. The solution may be applied with a small piece of clean linen, attached to the end of a short stick ; the linen to be renewed at each subsequent application. ... In about twelve hours it will be seen whether the solution has been well applied. If any inflamed part be unaffected, the solution must be immediately re- applied." The method of Mr. Higginbottom is extremely effective in trau- matic erysipelas. The common facial erysipelas rarely requires any- thing but the simplest application. The concentrated solution of ni- trate of silver should be thoroughly applied to malignant carbuncle of the lip, and to the adjacent healthy skin for a short distance. The pit- ting of small-pox may be prevented by rupturing each pustule and in- serting into it a sharply-pointed pencil of the nitrate of silver. Ac- cording to Mr. Higginbottom, the. same result may be accomplished, and with greatly less labor, by applying his solution in the manner above indicated. The solution of nitrate of silver in nitric ether (3ij — § j) is recom- mended by Fox in the chronic forms of erythema, eczema, psoriasis, and ringworms. Indolent idcers, discharging sores with flabby granula- tions, are improved in character and made to heal by application of Higginbottom's concentrated solution, or of solid caustic. Ulceration of the cervix uteri, endo-cervicitis, granular cervicitis, endo-metritis, are effectively treated by nitrate of silver applications. The solid caustic may be quickly brushed over the mucous membrane, or a concentrated solution may be applied with a suitable " applicator." SILVER. 267 There is no doubt that solid caustic may be applied with safety in chronic cases to the interior of the uterine cavity, after preliminary dilatation of the cervical canal. This is a most effective treatment, but injury is often done by over-stimulation and too prolonged con- tact of the caustic. Induration of the cervix and narrowing of the cervical canal are sometimes produced by injudicious use of the solid caustic. That troublesome affection, pruritus of the vulva, may often be removed, even when due to pregnancy, by washing the neck, and the cervical canal so far as it is accessible, with a strong solution of the nitrate of silver (3 j — 3 j). When the pruritus is due to a vesic- ular eruption on the genitals, the application should be made to the affected part. Gonorrhoea (vaginal) of the female is most quickly removed by applying through the speculum, and to every part of the canal, a concentrated solution of silver nitrate (3 j — 3 j). In the male, gonorrhoea, at its first appearance, may sometimes be aborted by a strong injection ( 3 j — 3 j), but unfortunately the period is usually past when this violent practice may be advised. Weak solutions (gr. j — grs. v — 3 j) are, as a rule, more efficient, as they are unquestionably safer. Cauterization of the prostatic part of the urethra was at one time vulgarized in the treatment of spermatorrhoea by the influence of Lallemand, but this dangerous practice is rarely necessary. The au- thor coincides with Mr. Furneaux Jordan in the expression of the be- lief that a vesicating solution of nitrate of silver applied to the peri- naeum is as generally useful and, of course, entirely without danger. Solutions of nitrate of silver are much used in ophthalmic and au- ral surgery. To granular lids, a strong solution (3j — 1 j) is ap- plied ; to acute conjunctivitis, a weak solution (gr. j — grs. iv — | j ); but generally ophthalmologists prefer the zinc and copper salts in the treatment of these affections. The incautious use of silver salts, when there are corneal ulcers, may result in unsightly deposits and opaci- ties. Otorrhoea, eczema of the external auditory meatus, and chronic inflammation of the external ear, may be cured by silver solutions properly applied. A commencing furuncle of the external canal may sometimes be aborted by application of Mr. Higginbottom's solution.. The stains made by nitrate of silver on fabrics or on the hands may be removed as follows : Moisten the spots and drop upon them a few drops of tincture of iodine, and wash with a solution of hyposul- phite of soda ( 3 ss — 3 j). These stains may also be removed by washing them with the following solution : Cyanide of potassium, 3 ijss ; iodine, grs. xv ; water, \ iij. Besides the above-mentioned external applications of nitrate of sil- ver, this salt is also used according to the method of Luton, entitled "parenchymatous substitution." This consists in injecting, with a hypodermatic syringe, a few drops of a concentrated solution into the parenchyma of organs — an irritant injection. Cystic tumors (wens), 268 AGENTS INCREASING WASTE. small fatty tumors, abscesses, and hydrocele, may be cured by inject- ing five to ten drops of a strong solution (3j — 3 ij). In the case of cysts and hydrocele, the contents may be allowed to escape through the needle, and then the irritant solution be injected. More or less active inflammation follows, and the sac, after a variable stage of sup- puration, becomes entirely obliterated. Old and intractable cases of sciatica that resist other means, includ- ing hypodermatic injection of anodynes, are sometimes permanently relieved by injecting deeply into the neighborhood of the affected nerve ten to twenty drops of a solution of nitrate of silver. Suppura- tion usually follows j and the local inflammatory process terminates the previously-existing nerve-lesion (parenchymatous substitution). Authorities referred to : Bartholow, Dr. Roberts.

Antagonists and Incompatibles. — Alkalies and their carbonates, lime-water, mineral salts (except the sulphates), iodides, and most astringent vegetables, are chemically incompatible with the salts of copper. In cases of poisoning, white of eggs and milk should be given freely, but evacuation of the contents of the stomach is necessary, for the albuminate of copper is not devoid of toxic power. The most COPPER. 269 effective chemical antidote is said to be the ferrocyanide of potassium, forming the insoluble ferrocyanide of copper. Magnesia has also been proposed, but it should not be relied on to the exclusion of albumen and ferrocyanide of potassium, nor should any antidote be used with- out evacuating the stomach contents by emetics or the stomach-pump. Synergists. — The salts of lead, tin, zinc, mercury, silver, gold, favor the therapeutic action of the copper-salts. All of these agents agree in this : they promote waste, and affect the functions of the nerv- ous system secondarily. All unfavorable hygienic conditions, which depress the functions of the body, increase the activity of the copper- salts. Physiological Actions. — The salts of copper have a styptic, me- tallic taste. When a poisonous dose of a copper-salt has been taken the following symptoms, referable to the digestive organs, appear : A strong metallic taste, burning and constriction of the throat, increased flow of saliva, burning pain at the epigastrium, with griping and colic- pain of the intestines, nausea and vomiting. The vomited matters have usually a bluish or greenish color, and the intestinal evacuations, which begin in a few minutes after the poison has been swallowed, are dark-greenish and frequently bloody. These are the symptoms pro- duced by the irritant poisons, and have no special characters, except, it may be, the color of the evacuations. The salts of copper, being diffusible substances, quickly enter the blood, and the systemic symp- toms which follow are referable to the nervous system and the organs of excretion. In the blood, as is the case with the other metallic poi- sons, copper probably exists in the form of an albuminate in close re- lation to the red blood-globules. The breathing becomes short, hur- ried, and labored ; the pulse small, quick, and weak ; the skin cold and perspiring, and restlessness, headache, trembling, cramps, vertigo, and stupor, are followed by convulsions (clonic or tetanic), paralysis, and insensibility. Inhalation of cupreous fumes, as in certain occupations in the arts, the slow introduction of small quantities, as occurs sometimes from cooking acid fruits in copper vessels, or the prolonged medicinal ad- ministration of moderate doses of a copper-salt, will produce the symp- toms of chronic or slow poisoning. When inhaled, the symptoms first observed are those of bronchial irritation and bronchial catarrh (Hirt). Internally administered, a gastro-intestinal catarrh is produced, epigas- tric pain is experienced, nausea, vomiting, colic, tenesmus, and dysen- teric discharges, and complete anorexia occur. The loss of appetite, and the interference with digestion, as well as the injury done to the red blood-globules, impair the strength and increase the waste of the tissues. A purplish line along the margin of the gum has been ob- served, salivation and ulceration of the gums not unfrequently occur, and occasionally jaundice is present as one of the symptoms. As re- 270 AGENTS INCREASING WASTE. gards the nervous system, headache, muscular trembling, paresis of the limbs, and sometimes paralysis, altered sensations, defects of co-ordi- nation, impaired mind, result. These nervous symptoms, with bron- chial and gastro-intestinal catarrh, are usually grouped together in the case of chronic cupreous poisoning in artisans. Copper is eliminated by the liver, intestinal canal, salivary glands, and kidneys. As is the case with the other metallic poisons, copper tends to accumulate in the liver. Therapy. — The sulphate of copper is one of the remedies some- times effective in the vomiting of pregnancy. For this purpose not more than one twentieth of a grain, three times a day, is admissible. B Cupri sulphat., grs. ij ; aquae destil., | ss. M. Sig.: Six drops a dose. As sulphate of copper is a very prompt and effective emetic, it is frequently resorted to in cases of narcotic poisoning. r> Cupri sul- phat., grs. vj ; aquae destil., § ij. M. Sig. : A tablespoonful every fif- teen minutes until vomiting ensue. It may be used under the same circumstances, but is by no means so desirable an emetic, in croup, as subsulphate of mercury. Minute doses of sulphate of copper render excellent service in gastro-intestinal catarrh, especially when the bow- els are relaxed. $ Cupri sulphat., gr. j ; ext. nucis vom., grs. iv. M.

When the food taken gives rise to colic, which is quickly followed by the incli- nation to stool, there should be combined with the above prescription one grain of morphine sulphate. When the constipation coexists with intestinal catarrh, the following prescription is useful : 3 Cupri sulphat., gr. j ; ext. physostigmae, ext. belladonna?, ext. nucis vom., aa grs. iv. M.

After the acuter symptoms have subsided, the sulphate of copper may be given with morphine and opium. Of all the metallic astringents employed for this purpose, sulphate of copper is the most effective in chronic diarrhoea and chronic dysentery. 3 Cupri sulphat., grs. j ; morphinae sulph., gr. j; quininse sulph., grs. xxiv. M. Ft. pil. no. xij. Sig.: One pill three times a day. Sulphate of copper is indicated when there are present colic-pains, tenesmus, and the stools, partly feculent, contain mucus streaked with blood. When tolerance is established, the quan- tity of copper in the above formulae may be increased slowly to one fourth of a grain. Rarely can more than one twelfth of a grain be given to an adult unaccustomed to its use, without causing very un- pleasant nausea and depression. The dysentery and cholera infantum of children, and the chronic COPPER. 271 enter •o-colitis which sometimes succeeds to measles, are often remark- ably benefited by minute doses of sulphate of copper. I£ Cupri sul- phat., gr. j ; tinct. opii deodor., gtt. viij ; aquae destil., 3 iv. M. Sig. : A teaspoonful every two, three, or four hours, for a child from one to two years of age. The sulphate of copper is a useful palliative astringent in the diar- rhoea of phthisis. It should be combined with opium. Kissel regards the salts of copper as curative in pneumonia, and the preparation which he prefers is the tincture of the acetate (Phar. Ger.). The mortality under this treatment was only 43 per cent. Am- moniated copper has been used recently with remarkable success in the treatment of facial neuralgia. It must be pushed (Fereol). The salts of copper, especially the cuprum ammoniatum, are among the numerous remedies employed in the treatment of epilepsy, chorea, and hysteria. Successful results have, it is true, been obtained by the use of these remedies, but at the present time they are rarely employed. External Uses. — The salts of copper do not act very energeti- cally on the unbroken integument. Applied to wounds they are as- tringent — that is, they combine with albumen, contract the tissues, and coagulate the blood. A crystal of sulphate of copper may be used to arrest bleeding from small wounds, e. g., from leech-bites. Indolent ulcers with flabby granidations can be stimulated to a renewed and more healthy activity by touching the affected surface with a crystal of sulphate of copper, or by frequent application of a solution (grs. ij — grs. x — I j). The following is an excellent injection in gonorrhoea after the acute stage : t> Cupri sulph., grs. iv ; morphinae sulph., grs. viij ; liq. plumbi subacetat., 3 j ; aquae rosae, 1 iv. M.

The application gives great pain, and is immediately followed by intense hyperaemia, which, however, subsides in a few hours, leav- ing the conjunctiva in much better condition than before. In scabies, a solution of sulphate of copper ( § j — Oj) has been used with great success, the lotion being applied after the crusts have been thoroughly removed with soap and water. An ointment of acetate of copper (grs. x — § 3) is a, very effective application in herpes circinatus (ringworm). The following formula has been recommended in menta- gra : I> Cupri sulph., 3 j ; zinci sulph., § ss ; aquae laur. -cerasi, § jss ; aquae destil. ad § xvj. M. Sig. : Lotion.

(Iodide of lead, 10 parts ; benzoinated lard, 90 parts.) Antagonists and Incompatibles. — Natural waters containing lime, sulphates, carbonates, carbonic acid, mineral acids and mineral salts, vegetable acids, alkalies, iodide of potassium, the vegetable astringents in general, albuminous solutions, and the preparations of opium, are incompatible. In cases of poisoning by acetate of lead, the proper antidotes are the sulphates of soda or magnesia, phosphate of soda, milk, and albuminous solutions. Emetics and the stomach- pump should be used. Synergists. — Cold, digitalis, ergot, veratrum viride, and agents acting similarly, favor the influence of acetate of lead over the circu- latory system. Copper, mercury, antimony, and remedies promoting waste, increase the depressing effects of lead on the nutrition of the body. Physiological Actions. — The acetate is astringent ; that is, it combines with albumen to form compounds, for the most part insolu- ble in water and in acids. All the salts of lead are more or less toxic. As the acetate, which is most frequently the preparation taken, has a sweetish taste, mistakes not unfrequently happen ; but the after-taste is decidedly astringent and slightly metallic. As the combination of the salts of lead with albumen takes place on contact, this action en- sues in the mouth in part, and is completed in the stomach. Any part of the lead reaching the intestinal canal must be converted into the insoluble sulphide. A very large quantity of the acetate of lead is required to produce a fatal effect ; not less than an ounce. When swallowed in this quantity and retained, it produces intense gastric irritation, sometimes choleriform symptoms, numbness, paralysis, coma, collapse. Owing to the fact that so large a quantity of acetate of lead will be rejected by vomiting, cases of acute poisoning rarely terminate fatally, and are infrequent. On the other hand, chronic poi- soning by lead is very common, owing to the use of cosmetics and hair-dyes containing lead, the use of food preserved in tin cans sol- dered with lead, and to the contamination of drinking-water. Yery rarely is the acetate of lead so persistently used in medical practice as to produce toxic symptoms. When lead is slowly introduced into the organism in small doses, the first symptoms usually observed are loss of appetite, failure of strength, more or less wasting, paleness of the face and of the integu- ment generally, and constipation. The joints become the seat of rheumatoid pain ; there is dry colic, the pain of which is assuaged by pressure ; and the muscles of the abdominal parietes are also seized with neuralgia. At the same time the liver diminishes in size, the abdominal fat disappears, the intestines are contracted, the belly is drawn in toward the spinal column. Coincidently with the contrac- 18 274 AGENTS INCREASING WASTE. tion of the liver, the skin assumes an icteroid hue, the conjunctivae be- come yellow, and the urine is tinged with the biliary coloring matters. At this time may be observed the so-called " blue line " along the margin of the incisor teeth — a slate-colored line, probably due to a deposition of the sulphide of lead, and found only, according to the author's experience, in those not accustomed to the use of a tooth- brush. The mucous membrane of the lips and mouth has often a blu- ish or slate-colored tint, and sometimes brownish pigment-deposits are seen on the lips near the teeth, and on the gums. Albuminuria may exist at this time, but it is commonly present further on in the history of these cases. Lead may cause that condition of hyperalbuminosis which eventuates in albuminous urine, but probably it in most cases hastens the development of changes in the kidneys already impending. As Garrod has conclusively shown, the use of lead, or its slow intro- duction through unknown channels, hinders the conversion of uric acid into urea, and favors the deposition of urate of soda about the joints : hence the arthritic pains which accompany the other symp- toms of chronic lead-poisoning, and the intimate relation of the pres- ence of lead in the organism and gouty attacks. The symptoms thus far sketched are chiefly those due to the influ- ence of the agent over the oxidation processes of the body in general. It is necessary now to consider the action of lead on the nervous sys- tem. Lead gastralgia is an early symptom, in part due to the fact that the metal acts directly on the nerves of the stomach, but it is also a symptom of the action of the poison on the central nervous system. Lead arthralgia, already referred to, is frequently an affection of the intra-muscular nerves, and has its seat more especially in the flexor muscles. The swelling of the joints and the joint-pains are doubtless due, as already explained, to the deposition of the urates in the joints themselves, but the term arthralgia is used to describe that form of pain about the joints produced by lead. Impaired sensibility to touch is also one of the phenomena of lead-poisoning. This lead-ancesthesia is found about the neck, chest, the forearms (their palmar face), hands, and fingers, and is symmetrically distributed on the two sides. An- aesthesia of the optic {amaurosis) is also a result of the direct action of lead, but dimness of vision and a sluggish pupil may also be due to the albuminuria which is so frequently present. Paralysis of the com- mon extensors of the fingers and of the supinators, while the power of the flexors and pronators is much less diminished, constitutes that very striking symptom of lead-poisoning, " the drop-wrist." When the arms are raised the hands drop forward and to the palmar face of the forearm, from an inability of the extensors to hold them up. Paralysis may invade the laryngeal muscles, producing aphonia. Sometimes the paralysis has the hemiplegic form, and, still more rarely, the paraplegic. At the beginning of the paralysis, the mus- LEAD. 275 calar irritability is preserved, but it soon lessens, and is lost finally, so that the muscles cease to respond to the faradic current. For some time after the induction current fails to excite contraction, muscu- lar movements may be obtained by a slowly- interrupted galvanic current. Death may result from the saturnine cachexia, by the gradual fail- ure of nutrition, and by the extension, finally, of the muscular paraly- sis to the muscles of respiration. Death may occur much earlier, by the development of those symptoms to which has been applied the term lead-encephalopathy — a form of disease characterized by delirium and convulsions, ending in fatal coma. Lead is very fatal to the life of the foetus, and women the subjects of the saturnine cachexia abort early, or produce stillborn children. After death, lead is found in various organs of the body, and rela- tively in large amount in the brain. It is also largely deposited in the substance of the affected muscles and nerves, and the destruction of the Hallerian irritability, the disappearance of the striation and the granular condition of the nerves, are probably due to the direct action of the metal. Lead, also, like the other minerals, tends to accumulate in the liver ; much of it is probably eliminated by the intestinal glands and skin, and some passes out by the kidneys. The treatment of lead-poisoning is prophylactic and curative. Among the former are, personal cleanliness, frequent bathing, the use of sulphuric-acid lemonade, the habitual employment of milk in large quantity as a food, and the avoidance of all sources of contamination. Among the curative measures must be placed first, large doses of the iodide of potassium, purgative doses of Epsom salts, and sulphur-baths. The affected muscles should be early faradized to prevent atrophic changes. When they fail to respond to a faradic current, a slowly- interrupted galvanic current should be used, and after a time the fara- dic irritability may be recovered. Therapy. — Acetate of lead is one of the astringent remedies em- ployed to arrest hmmatemesis. It is more especially adapted to the vomiting of blood which accompanies gastric ulcer. This salt exercises a favorable influence over the course and progress of gastric ulcer ; it allays pain and local inflammation, and modifies the ulcerated surface. In chronic gastric catarrh with gastralgia and pyrosis, it has given great relief. Notwithstanding the chemical incompatibility, it may be advantageously combined with morphine in painful stomach-affections. The most frequent use of the acetate of lead in gastro-intestinal dis- orders is in the treatment of the various forms of diarrhoea. It is an excellent remedy in the summer diarrhoea of children. 1^ Plumbi acetat., grs. viij ; acid, acetic, gtts. vj ; tinct. opii deodor., gtts. iv ; aquae destil., f j. M.

Ft. pulv. no. xii. Sig. : One powder every hour or two. It is sometimes preferable to administer the acetate of lead in solution, when the for- mula above given for children may be used in corresponding dose for adults. Probably, the most generally successful remedy for the diar- rhoea of phthisis is a pill containing equal parts of acetate of lead and opium. The diarrhoea of typhoid may also be restrained by acetate of lead and opium ; but generally bismuth is more suitable than acetate of lead. In acute and chronic dysentery lead is often a useful astrin- gent. Enemata of lead and morphine (5 Plumbi acetat., grs. iv ; morphinae acetat., gr. ss; aquae fervid., | j) allay the tenesmus of acute dysentery. Enemata of corresponding strength to age, of the same composition, are very useful in the cholera infantum of children. Although the salts of lead undergo important chemical changes in the intestinal canal, and are probably very much modified in composi- tion before they enter the blood, yet there is no doubt about their power to affect remote parts. The value of acetate of lead in various forms of haemorrhage has been attested by an immense clinical expe- rience. Thus, in haemoptysis, it is a most useful haemostatic. Careful observations on a case of severe and protracted pulmonary haemorrhage demonstrated that five grains of the acetate, every three hours, exer- cised a remarkable influence over the arterial tension and the action of the heart. Its effects are similar to those of digitalis : it slows the action but increases the power of the heart, while at the same time it elevates the tension of the arterioles. The astringent is, however, a dynamical and not a chemical action, doubtless. There is, therefore, a fitness in the prescription of Oppolzer for caseous pneumonia : Tji Inf. digitalis, 3 iv ; plumbi acetat., 3 j ; tinct. opii, 3 j. M. Sig. : A table- spoonful twice a day. A similar combination is serviceable in haemop- tysis: fy Plumbi acetat., 3i] ; pulv. digitalis, 3] ; pulv. opii, grs. x. M. Ft. pil. no. xx. Sig. : One every four hours. By virtue of its astringent action acetate of lead restrains secretion, and hence its utility in bronchorrhoea. It is also serviceable in humid asthma and whooping-cough. Formerly acetate of lead was used to quiet the action of the heart in hypertrophy -, and to favor coagulation of the blood in the case of internal aneurism. It might often be usefully employed in these af- fections now. In prescribing the preparations of lead for internal use, the danger of producing plumbism should not be overlooked. When it is used for any considerable period, the gums should be frequently inspected, and on the slightest appearance of a blue line, or on the occurrence of constipation and abdominal pain, the remedy should be at once discon- tinued. LEAD. 277 External Application of Lead Preparations. — The uses of lead preparations for external diseases are numerous and important. An excellent application to burns is white-lead paint — carbonate of lead and linseed-oil. This may be objectionable when the surface is very large, lest a dangerous amount of absorption take place, but for burns of small extent it is safe and gives great relief. The surface of the burn is thickly coated with the paint. Lead-lotion (liquor plumbi subacetatis dilutus) is a good application to eczema when there is much weeping. The following ointment has been recommended in this af- fection : $ Plumbi acetat., 3 ss ; camphor, pulv., grs. xv ; ol. amyg- dal., § ij ; cerre flavse, § j. M. Ft. cerat. An excellent formula for eczema, when there are great heat and redness, and profuse discharge, consists of liquor plumbi subacetatis, § j ; glycerine, § ss ; and cherry- laurel water, 3 iijss. The following formula is recommended by Fox in eczema and lichen: 3 Acid, nitrici dil., 3 ss ; plumbi acetat., grs. v ; aqua3, | vj. M. In erythema the carbonate of lead is used with advan- tage : I£ Plumbi carb., grs. iv ; glycerinse, 3 j ; cerat. simplicis, § j. M. In impetigo the following : fy Plumbi acetat., grs. xv ; acid, hydro- cyan, dil., ttl xx ; alcoholis, 3 ss ; aquae, 3 vss. M. Lead lotions are much used to cure muco-purulent and purulent discharges from the ear, the vagina, and the urethra. They may be employed at any stage, and the existence of inflammation does not contraindicate their use. The following is a useful formula for gonor- rhoea: fy Liq. plumbi subacetat. dil., 3 iv ; zinci sulphat., grs. viij. M. Sig. : As an injection. A chemical change, of course, takes place, but clinical experience is in favor of the combination. The ointment of the iodide of lead is often a useful application to enlarged lymphatic glands and to enlarged spleen. It is also employed with benefit in cases of chronic eczema, porrigo, and psoriasis. A solution of the nitrate of lead in pure glycerin (grs. x — 3 j) is an effective application to fissured nipples. It need hardly be re- marked that the nipple should be well w r ashed before the child is per- mitted to suck. Nitrate of lead in form of powder, dusted over the unhealthy granulations, gives great relief, and hastens the healing of onychia. Authorities referred to : Garrod, Dr. A. B.

Antagonists and Incompatibles. — Lime-water, the alkalies and their carbonates, nitrate of silver, and the vegetable astringents, are incompatible with zinc-salts. The acetate of lead is also incompati- ble, but a solution containing sulphate of zinc and acetate of lead, not- withstanding the double decomposition which ensues, is an effective ZINC. 279 injection in gonorrhoea. With valerianate of zinc, acids, many of the metallic salts, soluble carbonates, and vegetable astringents, are incom- patible. The antidotes to be used in cases of poisoning by the zinc- salts are lime-water, mucilaginous drinks, milk, tannic acid, the carbon- ated alkalies, common soap, etc. Synergists. — The mercurial, silver, antimonial, and copper prepa- rations favor the action of the zinc-salts. Physiological Actions. — The preparations of zinc are active in proportion to their solubility and power of diffusion. The chloride, the sulphate, and the acetate, are the most active, and in the order in which they are placed ; the carbonate and the oxide being insoluble, have very feeble diffusive power, and possess consequently very slight activity. The chloride is a very active escharotic. Applied to the denuded integument, it sets up decided inflammation, and produces an intense burning pain, followed by sloughing. Owing to its great affin- ity for water and power of combination with albumen, it penetrates deeply and widely, and the eschar which it produces is thick, hard, and white. The dried sulphate of zinc (deprived of its water of crys- tallization by heat) is also feebly escharotic when applied to an open wound. Solutions of the sulphate and acetate act locally as astringents by combining with albumen. The soluble salts of zinc have a styptic metallic taste, which is very disagreeable. The sulphate of zinc is a very prompt and efficient emetic, acting without much preliminary nausea, and without much constitutional depression. It is a specific emetic ; it acts to produce emesis when injected into the veins. Long-continued use of the sul- phate, even in small medicinal doses, may excite ulceration of the mu- cous membrane. The oxide and carbonate, although insoluble and in- active, slowly produce systemic effects. The chloride is a powerful irritant poison, causing heat and a sense of constriction of the throat, a strong metallic taste, burning at the stomach, nausea, vomiting, great depression of the pulse, coldness of the surface, cold sweat, cramps of the legs, etc. The mind is unaffected. In a few instances nervous symptoms have followed, besides the cramps, and in one no- table case there was loss of the senses of taste and smell. All of the salts of zinc, when long continued, may produce a train of symptoms not unlike those caused by lead, viz., emaciation, pallor, loss of strength, constipation and colic, muscular weakness and trem- bling, paralysis, etc. The oxide in large doses, and used for a long period, has produced wasting, a fetid breath, gastro-intestinal catarrh, weakness, and feeble mind. The zinc-salts most probably exist in the blood in the form of al- buminate, and in close relation to the red blood-globules. They mani- fest much less tendency to accumulate, and are excreted much more rapidly than mercury, lead, and copper. They diffuse out of the blood 280 AGENTS INCREASING WASTE. chiefly by the liver and intestinal glandular apparatus, and are found in great quantity in the faeces. To a slight extent they are also ex- creted by the kidneys. Therapy. — The sulphate of zinc is much employed as an emetic in cases such as narcotic poisoning, where prompt and efficient action is necessary. Six grains will generally prove sufficient. It may be re- peated every fifteen minutes, well diluted with water, until emesis oc- curs. It was formerly much employed as an emetic in croup, but now tartar-emetic, but especially the subsulphate of mercury, is preferred. The oxide of zinc is an excellent remedy for gastralgia. It is indi- cated also in the following state of things : pain after taking food, nausea, intestinal pain, succeeded by prompt alvine discharges, the faeces being made up largely of undigested food. From five to ten grains mixed with aromatic powder and combined with morphine, if need be, may be given before each meal. In the summer diarrhoea of children, it is a very efficient remedy. It may be administered with bismuth and pepsin. $ Bismuthi subnitrat., 3 j — 3 ij ; pepsinae sacch. (Sheffer's), 3 ss; zinci oxidi, grs. vj — grs. xij. M. Ft. pulv.no. xii. Sig. : One poivder every four to six hours. In the chronic diar- rhoea both of children and adults the oxide of zinc (from two to ten grains) is serviceable under the same circumstances in which bismuth is presumed to be indicated, but it is a less pleasant remedy in action than the latter. The sulphate (gr. ss — grs. ij) often gives great relief in that form of dyspepsia which is the cause of oxaluria. In small doses, the sulphate, like most of the mineral remedies of this group, increases for a time the appetite and digestive capacity, but this effect is soon succeeded by gastro-intestinal catarrh, nausea, and loss of appe- tite. The sulphate, as well as the oxide, is an astringent ; it arrests the peristaltic movements and causes constipation, and is therefore an appropriate remedy in chronic diarrhoea and chronic dysentery. In its action and results it is similar to but less efficient than sulphate of copper. It may be combined with opium and ipecacuanha : 1^ Zinci sulphat., pulv. opii, pulv. ipecac, aa grs. xij. M. Ft. pil. no. xij. Sig. : One pill three or four times a day. The zinc preparations possess undoubted efficacy in certain disorders of the thoracic organs. The night-siceats of phthisis are often pre- vented by a pill of oxide of zinc and extract of belladonna (three grains of the former and half a grain of the latter) given at bedtime. The zinc is serviceable without the belladonna, but the combined action is more efficient. The sulphate of zinc, by virtue of its astringency, has been prescribed in bronchorrhcea, but other agents are now pre- ferred. The oxide of zinc is a serviceable prophylactic against the recurrence of the attacks of spasmodic asthma. It is also one of the numerous remedies which has been used with a varying degree of suc- cess in whooping-cough : ^ Zinci oxidi, 3 j ; ext. belladonnae, grs. v. ZINC. 281 M. Ft. pil. no. xx. Sig. : One pill three times a day as a prophylactic for asthma, and as a remedy for whooping-cough. The sulphate of zinc (gr. \ — gr. j) and extract of belladonna (gr. \ — gr. ss) may be used in combination for the relief of the same cases. It is highly probable that the sulphate of zinc, being more soluble, is much more efficient in the treatment of these neuroses of the digestive organs than the oxide. The preparations of zinc exert an influence upon the nervous system which has been and is called antispasmodic. In certain disorders of the nervous system, of which the chief manifestations are spasm and convulsion (clonic), they are sometimes very serviceable. Much has been said for and against the oxide of zinc as a remedy for epilepsy. A few cases are improved by it ; in the great majority it fails utterly. The author expresses with diffidence his conviction that this remedy is most useful in those cases in which the peripheric irritation has its origin in the stomach ; it acts by allaying irritability of the terminal filaments of the pneumogastric, and probably also by removing a dis- eased state of the gastric mucous membrane. Epileptiform vertigo and epileptiform angina pectoris, when they arise (as they not unfre- quently do) from gastric disorder of some kind, are sometimes cured by the oxide of zinc. The so-called nervous headache of hysterical women, nervous cough, and aphonia, due to uterine and ovarian irri- tation, are often relieved by the valerianate of zinc. Sulphate of zinc is one of the numerous remedies for chorea, acting in a manner similar to arsenic, but inferior to this agent in curative power. In neuralgia due to reflex irritation from the female pelvic organs, the preparations of zinc, notably the valerianate, are often extremely beneficial. r> Zinci valerianat., 3 j ; ext. gentianse, 3 j ; ext. nucis vom., grs. v.

M. Ft. pil. no. xx. Sig. : One pill three or four times a day. External Uses. — The author has personal knowledge of several cases of caries cured by the injection of Villate^s solution. The fol- lowing is the composition of this fluid : Sulphate of copper, sulphate of zinc, of each 15 parts ; solution of subacetate of lead, 30 parts ; vinegar, 200 parts. The sinus or sinuses leading to the carious bone should be thoroughly injected with the solution. It need hardly be remarked that this treatment would not remove a sequestrum. An excellent caustic for the destruction of lupus, epithelioma, and unhealthy ulcers, is the dried sulphate of zinc, which may be freely dusted over the affected surface. A superficial slough forms, the sepa- ration of which may be aided by a poultice. The most efficient escha- rotic consistent with safety is the chloride. No danger is to be ap- 282 AGENTS INCREASING WASTE. prehended from its absorption, and the strength of the application may be easily regulated. For the destruction of malignant growths, chloride of zinc is applied of varying strength, by the admixture of different proportions of flour, or better, of powdered althea-root, so as to form a paste, sufficient water being added. One part of the chloride to two, three, four, or five parts of flour are the proportions advised by Dr. Can quoin. Instead of flour, the chloride may be mixed with anhydrous sulphate of lime. A very convenient and useful mode of applying chloride of zinc is, to mix it, while in a finely-powdered state, with its weight of gutta-percha melted with as little heat as possible. The mixture may be molded into any desired shape. The so-called " caustic arrows " are nothing more than chloride-of-zinc paste, dried and cut into arrow-like slips. These are inserted into the malignant growth, usually at its base, in order to separate it from the healthy tissues. The salts of zinc are useful applications to certain forms and stages of skin-diseases. In eczema, during the secretory stage, the following may be used : 3 Zinci oxidi, 3 ij ; glycerinae, 3 ij ; liq. plumbi sub- acetat., 3 jss ; aquae calcis ad § vj. M. Sig. : Lotion (Fox). This formula is serviceable also in impetigo and herpes. An excellent ab- sorbent powder for excoriated surfaces is the following : I£ Corn-meal, finely sifted, f iv ; oxide of zinc, J j ; iris powder, § ss ; oil of almonds, gtts. x. M. The following is recommended by Neumann in sebor- rhea, when there is inflammation : 1^ Zinci oxidi, 3 j ; plumbi car- bonat., 3 j ; cetacei, § j ; ol. olivae q. s. ft. ung. Sig. : Ointment.

For erythema and herpes, the following may also be used : ^ Zinci acetat., grs. ij ; aquae rosae, 3 j ; ung. aquae rosae, § j. M. Sig. : Ointment. The ointments of the oxide of zinc and the cerate of the carbonate are excellent applications in many of the cutaneous affections above named.

None of the other preparations are employed by modern physicians. Antagonists and Incompatibles. — Tannic and gallic acids, and vegetable infusions containing them, form an insoluble tannate, and are therefore incompatible. Alkalies and the salts of lead decompose tartar-emetic. It follows that the proper antidotes to poisoning by tartar-emetic are tannic acid and substances containing it. Opium, alcohol, ether, etc., and the antispasmodics generally, are physiologi- cally antagonistic. Synergists. — The mineral substances of this group promote the ac- tion of the antimonials ; also the emetics and cathartics, and depress- ing remedies generally, as veratrum viride, etc. Physiological Actions. — Tartar-emetic has a sweetish, styptic, and metallic taste. In small medicinal doses, it excites a sensation of warmth in the stomach, followed by nausea, increased flow of saliva and buccal mucus, an abundant secretion of the gastric and intestinal glandular apparatus, and also of the liver and pancreas. In somewhat larger doses — a half-grain to one or two grains — it excites vomiting, first of the contents of the stomach, then of gastric mucus, and after- ward of mucus and biliary matters. The alvine dejections are more fluid and increased in number, and consist at first of fluidified faeces ; afterward they are made up of a colored liquid, in which there are present biliary matters and some faeces ; and, finally, there appears only a colorless or whitish liquid, having flocculi of epithelium floating in it, and bearing a striking resemblance to the " rice-water discharges " of cholera. The gastro-intestinal symptoms are accompanied by systemic dis- turbance — paleness of the face, coldness of the surface (sometimes pre- ceded by a very temporary rise of temperature), irregularity and fee- bleness of the pulse, and great nervous and muscular prostration. When the quantity is sufficient to cause lethal symptoms, they are as follows : epigastric pain, vomiting and purging, shrunken features, cold breath, cyanosis, arrest of the urinary secretion, aphonia, cramps — the assemblage of symptoms belonging to the collapse of cholera. Tartar-emetic, w T hen used in considerable medicinal doses, sets up an irritation of the fauces followed by aphthous ulcerations, which con- tinue along the oesophagus to the stomach, and are accompanied by salivation and painful deglutition. Applied to the skin by friction, tartar-emetic excites a follicular inflammation, succeeded by a papule, a vesico-pustule, a surrounding inflammation with indurated base, a central umbilication, and finally desiccation, terminating in a brownish scab. These antimony-pustules are very similar to those of vaccine or variola. When applied to the skin or injected into the veins, tartar-emetic is absorbed, and manifests a selective action on the gastro-intestinal ANTIMONY. 285 mucous membrane, causing the same irritant effects as are produced by its stomach administration. It is, therefore, a specific, and not a merely irritant emetic. Tartar-emetic readily diffuses into the blood. In what form, unless as an albuminate, it exists in the blood, is not understood. It dimin- ishes the number and force of the arterial pulsations, and rapidly low- ers the blood-pressure. The pulse may fall from 72 to 40, but, accord- ing to Hirtz, rarely is the number reduced more than 6 to 10 per min- ute. In the healthy subject, the normal temperature, even when a full medicinal dose has been administered, remains unaffected as to the trunk, but it may be reduced in the extremities. In fevers and inflammations, a considerable reduction of temperature may take place, and the same result has been noted in the physiological state when the quantity of tartar-emetic has been sufficient to produce choleriform symptoms. In man delirium, and in animals paralysis, motor and sensory, but without impairment of muscular contractility, have been observed from lethal doses of tartar-emetic. Tartar-emetic promotes waste and hastens the elimination of the products of waste — the excretion both of carbonic acid and of urea being greatly increased by it. The antimonial salts are found in the blood, in the liver, and other viscera, and are excreted by the bile, the milk, the perspiration, and the urine. It is, doubtless, also largely excreted by the intestinal glandular apparatus, as is the case with the metals generally. If tartar-emetic is administered in small doses, and the quantity be gradually increased, the nauseating effects of the drug may be en- tirely prevented. When emetic doses even are continued in some subjects, this effect finally ceases, and the drug is borne without pro- ducing any gastric symptoms. To this state has been applied the term tolerance, by the contra-stimulant school of practitioners. It must not be lost sight of, that this tolerance, on the part of the stom- ach, of large doses does not mean an indifference to the action of the remedy, but very serious and profound anatomical alterations may result. Therapy. — Tartar-emetic was, formerly, much more frequently prescribed than at present as an emetic in cases of indigestion charac- terized by a coated tongue, loaded stomach, and anorexia {Vembarras gastrioue). It is sometimes used as an emetic in cases of narcotic poi- soning, but sulphate of zinc is preferable. It was formerly used as an emetic in the first stage of typhoid and other fevers, but, notwith- standing this practice is frequently followed by good results, it is now rarely pursued. If emesis is desirable in these cases, a less irritating and depressing emetic should be used. In croup tartar-emetic is an efficient emetic, but it must be used 286 AGENTS INCREASING WASTE. with caution, owing to the great depression which it produces, and the fatal result which has occurred in many instances. It is not a suitable remedy for infants and very young children. The compound sirup of squills is a domestic remedy for croup, but the incautious use of this has proved fatal. Tartar-emetic is used in laryngismus stridulus to produce emesis and consequent relaxation of the muscles of the larynx, and in true croup to cause the expulsion of the false membrane. The yellow subsulphate of mercury is safer and quite as effective. Tartar-emetic is an excellent remedy in the first stage of acute ca- tarrh, nasal, pharyngeal, and bronchial. It is most efficient in the first stage, when the mucous membrane is dry and swollen. It pro- motes secretion, diminishes fever, induces diaphoresis, and hastens the elimination of inflammatory products. In these cases, from one twentieth to one twelfth of a grain is usually a sufficient quantity, for it is not necessary that nausea be excited. When cough is violent, a little opium may be added to the prescription. $ Antimonii et po- tassii tart., gr. ss ; morphinae acetat., gr. ss ; aquae, § ij. M. Sig. : A teaspoonful every hour or two. In acute bronchitis, when the cough is dry and hoarse, this agent is useful, and small doses (one sixteenth of a grain), frequently repeated, are more serviceable than large doses at longer intervals. Formerly, under the influence of the contra-stimulant school, tartar- emetic was given in large doses in pneumonia. It was sought to es- tablish tolerance at an early period, and to administer the largest doses which could be borne. The comparative results of this method of treatment and of the expectant and restorative plans demonstrate the impropriety of the tartar-emetic treatment, and it is now abandoned. It is true that small doses of tartar-emetic, by increasing the action of the skin, kidneys, and intestinal canal, may exert a favorable influence over the temperature and diminish the plasticity of the exudation ; but even small doses must be employed with care, lest a depression should be induced which may interfere seriously in the natural course of a disease which is self -limited and has its period of crisis. Tartar-emetic gives great relief in spasmodic asthma when the bron- chial secretion is deficient, and in those cases brought on by an over- loaded stomach. In the former case small doses frequently repeated until very slight nausea is produced, and in the latter emetic doses, are necessary.

M. Sig. : A teaspoonful every two, three, or four hours. The ointment of tartar-emetic was formerly much employed to pro- duce pustulation of the chest in the more chronic pulmoriary diseases. This painful and disfiguring form of counter-irritation has passed out CADMIUM. 287 of use. To produce a crop of variolus-like pustules on the skin does not cause a morbid process like caseous pneumonia or tuberculosis to cease its ravages ; on the contrary, such extensive suppuration in the skin rather favors the development of these diseases. A combination of tartar-emetic and opium is a serviceable hypnotic in some cerebral disorders. These remedies appear to be most useful when wakefulness and delirium are due to cerebral congestion, and in those subjects who become excited and wakeful from the use of opium alone. In the active delirium and wakefulness of typhoid fever, tartar-emetic and opium are prescribed : 1^ Antimonii et potassii tart., gr. j — grs. ij ; morphinse sulph., gr. jss ; aquae lauro-cerasi, J j. M. Sig. : A teaspoonful every two, three, or four hours. In delirium tre- mens, when the same conditions exist, the same combination may be prescribed. Since the introduction of chloral and bromide of potas- sium, however, the use of these drugs for the purposes just indicated has been much restricted. In acute inflammatory and febrile diseases, minute doses of tar- tar-emetic (gr. -^q), frequently repeated, render an incontestable ser- vice. Typhoid, typho-malarial, and remittent fevers, acute rheumatism, erysipelas, etc., are maladies thus benefited. This remedy is, of course, contraindicated when there is much irritability of the stomach and intestinal canal. At the outset of fevers it was formerly the custom to prescribe an active emetic, and good results certainly followed this practice. The author believes that he has frequently seen impending attacks of malarial fever aborted by emetic doses of antimony and ipecac. Free emeto-catharsis moderates the severity of remittent fever in robust subjects when produced in the incipiency of this disease, and also puts the mucous membrane in a better state for the disposition of medicines and food. Before the days of anaesthesia tartar-emetic was much used to relax the muscidar system for the reduction of dislocations, to facilitate the taxis in strangulated hernia, to relax rigid os and perineum in labor, etc., but it is now no longer employed for these purposes.

Action and Uses. — There is a strong resemblance— an identity of action, indeed — between zinc and cadmium, except that the latter is the stronger. Cadmium has a decidedly caustic and astringent taste ; it is powerfully nauseant and emetic, producing great depres- sion of the powers of life. Locally the effects are those of an irritant poison, and the systemic effects correspond ; although there are pro- duced such cerebro-spinal symptoms as coma and convulsions. This agent is not administered internally, the preparations of zinc being preferred for all purposes to which cadmium might be applied as a remedy. In ophthalmic practice, cadmium seems to be much esteemed as a colly Hum. It is held to possess special powers in causing absorption of opacities of the cornea : $ Cadmii sulph., grs. ij ; aquae rosoe, § j. M. Sig. : Colly Hum. A solution of the same strength is said to be an excellent local application in otorrhcea. There is no doubt that cadmium is an efficient injection in gonorrhoea ; but it is important in the application of this, as of so many other astringent remedies, that it be not too strong — one grain of cadmium sulphate to four ounces of water being sufficient in most cases. An ointment of cadmium is used somewhat by French physicians, in the treatment of external affections. For this purpose we may di- rect ten grains of the sulphate to be intimately incorporated with an ounce of simple ointment. Cerium. — Cerii Oxalas. — Oxalate of cerium. A white powder, in- soluble in water, alcohol, and ether. Dose, two to five grains in pill- form, as it is insoluble in the ordinary menstrua. It may be suspended in mucilage. Sir James Simpson was the first to propose the use of oxalate of cerium to restrain vomiting arising from various causes, especially from pregnancy ; and he brought forward many cases illustrative of its value. As he pointed out, it sometimes succeeds immediately, but usually the best effects are experienced after several days' use. The oxalate of cerium sometimes succeeds remarkably in vomiting due to serious organic lesions, as in cancer (Peters). It has been narrated in one case, that four grains were administered every two hours until about 600 grains were taken. The good result which followed this large administration of the drug indicates that, in vomiting from simi- lar causes, larger doses may be sometimes necessary to secure the best curative effects. In chronic diarrhoea, cerium may take the place of bismuth. In cases of cough associated with vomiting, excellent results have been obtained from the oxalate of cerium. It is probable that the cough is reflex in origin, the point of irritation existing in the terminal filaments of the pneumogastric in the gastric mucous membrane. METALLOTHERAPY. 289 Met allot her apy. — Definition and Historical Development. — By the term metallotherapy is meant a curative method in which metals are applied to the affected area. The alchemists entertained extravagant notions of the therapeu- tical results to be achieved by the application of metals to the surface of the body. The influence of the noble metals over the bodily func- tions has been believed in from the remotest times within the histori- cal period, and this belief has been acted on by many influential per- sons down to nearly our own era. The action of magnetic iron contributed to this mystical notion. Then came the wonder-work- ing Mesmer. To the action of magnets was added that mysterious force evoked by the agencies employed by the Mesmerists. From such elements a pretended system of cure was elaborated, and a great many charlatans throve on the profits of this " system " of practice. Probably the most sustained success in this department of popular fallacies was effected by Dr. Perkins, of Connecticut, who invented a combination of metals arranged in the form of a cylinder, about six inches in length and two inches in circumference, which he called a tractor. Provided with a suitable handle, the tractor was slowly passed over the affected area, and the morbid process was drawn out or dis- persed. Perkins's tractors excited great interest in this country, and in England an immense enthusiasm. An institution — known as the Perkinian Institute — was established in London, and many of the no- bility and gentry resorted to it to be cured by the application of the tractors. In a book published by the son, there may be found many certificates of cures thus effected. These results are the less surprising when interpreted by the aid of subsequent developments from metal- lotherapy. Mesmer, Perkins, Hahnemann, appeared nearly simultane- ously, and each had an influence on the thought of the time. Metallotherapy, as now understood, had its origin in the experi- ments of Dr. Burq, which were first announced in a note addressed to the Academy of Sciences, and subsequently embodied in his thesis for the medical doctorate in 1851. He stated that a plate of metal — a sil- ver coin, for example — applied to the skin, may remove the paralyses of motility or of sensibility occurring in hysteria ; that the same metal was not equally successful in all cases, and that idiosyncrasies exist, so that in respect to each individual there is a special metal, active and cu- rative. In one subject it may be gold, in another silver, and in a third copper, which has the power to restore the lost motility or sensibility. Burq also maintained that the same metal taken internally, whether in the form of a natural mineral water or in a pharmaceutical preparation, produced the same result. In other words, when a piece of metal, a coin, selected according to the special sensibility of the subject, is ap- plied to an hysterical patient having permanent hemianesthesia, the return of the normal sensibility is effected in from ten to twenty minutes 19 290 AGENTS INCREASING WASTE. through a space of some extent, above and below the point of appli- cation. Numbness, tingling, and other disorders of sensation, dyses- thesia, etc., precede the return of sensibility to the anaesthetic area. The restoration of the sensibility proceeds from the point of applica- tion of the metal, and enlarges in all directions until the whole side returns to the normal. At the same time, an elevation of the temper- ature recognizable by the thermometer, and an increase of motor power as shown by the dynamometer, take place. These changes in the state of the sensory nerves are coincident with dilatation of the capillaries. The special senses undergo the same modifications. Sight, hearing, taste, and smell, are also in the condition of anaesthesia, and as the general sensibility is restored, these special organs return to their nor- mal state. Such, in brief, were the facts announced by M. Burq. A commis- sion, with M. Charcot at its head, was appointed to investigate the phenomena of metallotherapy. Hitherto the statements in regard to the effects of metals had been received with positive incredulity ; but the commission not only confirmed the accuracy of Burq's observations, but added some new facts. The first discovery made by them was the phenomenon of " transfer." By this term is meant a transference of functional powers. When the sensibility, the temperature, and the muscular power are restored to the side which had been anaesthetic, the other or normal side loses a part of its general and special sensibility. The commission also ascertained that when metals are applied for the relief of hemianaesthesia due to old organic lesions of the nervous cen- ters (such, for example, as cerebral hemiplegia), sensibility is restored also, but in a more durable manner. Thus, in a case of anaesthesia of ten years' duration, produced by a cerebral lesion, this symptom yielded to the application of gold. Other instances of the same character, and equally significant, were reported by the commission. These facts led Charcot to entertain the supposition that the effects produced by the application of the metals are really due to electrical action. It was ascertained, indeed, that electrical currents measurable by the galva- nometer are caused by the contact of the metals, and, conversely, that electrical currents of corresponding strength induced the same results as the metals, including the phenomena of transfer. The intensity of the current varies with the metal. In the case of a patient impression- able to gold, a current of two to twelve degrees suffices to restore the sensibility and the muscular force, while in one sensitive to copper, a current of forty to fifty degrees is required to effect the same result (Petit). As was above stated, when the metal to which the subject is found to be sensitive when applied locally, is given by the stomach, the same result is reached — that is, the anaesthesia is replaced by normal sensi- bility, the temperature rises to the natural level, and the muscular METALLOTHERAPY. 291 power is restored. The commission discovered the remarkable fact that if, after the normal is thus resumed, the metal is again applied, the original anaesthesia comes on. To this return anaesthesia Charcot has applied the term metallic ancesthesia. A feeble electric current applied under the same conditions produces, also, a return anaesthesia, which is called postelectric. When the metallic plates applied to the skin are composed of metals superimposed, the same results as those obtained by a single metal are not produced. Thus, if in a patient sensible to gold a piece of silver is laid on the gold, the effects proper to the latter do not follow. The results due to the application of gold may be ren- dered durable in some cases by superimposing a piece of silver. If, after the effects produced by the application of a metal to which the patient is sensitive, another metal is placed above the first, the results due to the former may be fixed or rendered permanent. Notwithstanding the incredulity with which these observations on the action of metals were at first received, they have come to be gen- erally accepted. Prof. "Westphal, after a study of metallotherapy at Paris, made some investigations at Berlin, which, on the whole, were confirmatory. Charcot's observations were also sustained by the ex- periences of Thompson, Horrocks, and Wilks. An important contri- bution to the subject was made by Dr. Hughes Bennett, when he found that other substances besides metals caused the same results. In this experience we have an illustration of the old and well-known fact that discoveries are being constantly reproduced. When the Perkins ex^ citement was at its acme, Dr. Haygarth, of Bath, announced that wooden cylinders made in imitation of the genuine tractors had the same curative effects. It is clear, however, as M. Yigouroux has well said, that not all substances have the same action. This fact has also been demonstrated by Dr. Hack Tuke, who, having caused the anaes- thesia to disappear by the action of a metal, substituted a piece of car- bon of similar size and appearance, but the effect did not follow. Actions and Applications. — Charcot, as has been stated, supposed that the effects produced by the application of metals were due to elec- trical action. This theory does not suffice to explain all of the effects. By Dr. Tuke, " expectant attention " was invoked to explain the phe- nomena, but this theory is not tenable. Yigouroux holds that the dif- ference in electrical tension of some point of the organism is the real explanation of the phenomena resulting from the application of metals to the surface. According to Burq, the order of susceptibility to the impression of metals is as follows, each individual, as a rule, being susceptible to one metal only : iron, copper, gold, silver, tin, platinum (only rarely). These metals are applied in the form of disks, or large coins, and some- times disks of wood coated with the metals. Some other substances, as mentioned above, have exhibited the same phenomena, but the met- 292 AGENTS INCREASING WASTE. als are unquestionably the most important. The metallic disks or coins are placed as a bracelet around the limb to be acted on, or individual disks are held in position by a bandage. The effects fol- low in a few minutes. The skin, previously pallid, cold, and without sensibility, becomes flushed, warm, and acutely sensitive, and in a short time the special senses are restored to their normal functional activity. As has been described, corresponding losses occur on the other side. Metallotherapy has been employed chiefly for the restoration of sensibility in cases of the hemianesthesia of hysteria, of paralysis of sensibility, in some instances of hemiplegia, and of certain functional paralyses of motility. It is not possible to formulate a set of rules for distinguishing the cases which will be benefited by these applications. Sometimes remarkable results are reached in a few applications ; then, again, unaccountable failures occur. Cases of writer's cramp, and of chorea, among the spasmodic af- fections, and neuralgia, have been suddenly cured by the use of the esthesiogenic metal ; but failures are greatly more frequent than the successes. When the metal to which the patient is sensitive has been ascertained, the further treatment may be conducted by the internal use of the same.

Ahtminis et Potassii Sulphas. — Potassa alum. A white, slightly- efflorescent salt, crystallizing in regular octahedrons, and possessing an acid, sweetish, astringent taste. It dissolves in from fourteen to fifteen times its weight of cold, and three fourths of its weight of boil- ing water, but is insoluble in alcohol. Alumen JExsiccatum. — Dried alum. Alum deprived of its water of crystallization by heat. A white, granular powder, odorless, but hav- ing a sweetish, astringent taste. Slowly but completely soluble in twenty parts of water at 60° Fahr. Aluminis Sulphas. — Sulphate of aluminum. Has a sour, somewhat ALUM. 293 sweetish, and astringent taste, and an acid reaction. It is soluble in twice its weight of water. Antagonists and Incompatibles. — Alkalies and their carbonates and acetate of lead are chemically inconrpatible. Synergists. — The mineral and vegetable astringents promote its therapeutical activity. Physiological Actions. — The sweetish taste of alum first experi- enced is quickly followed by a decided astringency. It provokes an abundant flow of saliva, and the albumen of the saliva and buccal mucus is coagulated in whitish, membrane-like flakes. Contraction of the capillaries, blanching of the mucous membrane, and subsequent diminution of secretion, take place ; hence the dryness of the throat, thirst, and constipation, which result from its use. In doses of a tea- spoonful, or more, alum is an efficient emetic. Under certain morbid states it also proves laxative. Notwithstanding its power to coagulate albumen, it is absorbed into the blood, as was shown by Orfila, and may be found in the liver and in the urine. Circulating in the blood, alum affects the capillaries, diminishing their caliber, lessens secretion, especially of the mucous membranes, and arrests haemorrhage. In very large doses alum produces decided irritant effects — nausea, vomiting, abdominal pain, diarrhoea, etc. Dried alum, in consequence of its strong affinity for water, and its power to coagulate albumen, is a mild escharotic. Theeapy. — Alum is one of the remedies which may be used in gastric catarrh. It is said to be most effective when there is vomiting of glairy mucus. Pjg Aluminis, 3 ij ; extract, gentian., 3 ss. M. Ft. pil. no. xxx. Sig. : Two pills three times a day. Alum is a service- able haemostatic in hcematemesis. It is, of course, adapted only to cases of passive haemorrhage, when there is a relaxed condition of the mucous membrane. Other astringents — as, for example, Monsel's salt — are more effective. When intestinal haemorrhage is dependent on mechanical causes (cirrhosis, for example), and the mucous mem- brane is free from acute inflammation, alum is a serviceable astringent. It was formerly much used in chronic diarrhoea and chronic dysentery, but more effective agents are now employed in these diseases. The following formulae are applicable to the above-mentioned diseases, in the absence of more suitable agents : I> Aluminis, 3 ij ; pulv. aromat., 3 j ; pulv. opii, grs. vj — grs. xij. M.

It is a singular fact that the most effective agent for the cure of colica pictonum is alum. It relieves the pain and nausea, and over- 294: AGENTS INCREASING WASTE. comes the constipation, more certainly than any other agent. The chemical theory of its action is entirely unequal to the explanation of its remarkable effects ; the conversion of any portion of the lead pres- ent in the intestinal canal into the insoluble sulphate would not suffice to quiet pain, relieve flatulence, and relax the obstinately constipated bowels. Its action is doubtless dynamical : it overcomes the relaxa- tion and paresis of the muscular layer, on which the phenomena of lead-colic depend. The following are convenient formulae for the ad- ministration of alum in this disease : I£ Aluminis, 3 ij ; acid, sulphuric, dil., 3 j ; syrup, liraonis, § j ; aquae, § iij. M. Sig. : A tablespoonful every hour or two. r^ Aluminis, 3 ij ; vini, § iv ; catechu, 3 j ; traga- canthse, 3 j ; aquae, § viij. M. Sig. : A tablespoonful every hour. Alum- whey, prepared as follows, may be used in lead-colic : To a pint of boiling milk, add ninety grains of alum-powder ; separate the curd, and sweeten the whey if desired with an ounce of white sugar. A wineglassf ul may be taken every hour or two. Alum not unfrequently affords relief in gastralgia, enteralgia, and catarrh of the intestines. It is a serviceable laxative in females of lax fiber, in whom constipation depends upon a paretic state of the muscu- lar layer of the bowel. It is true that we possess many other agents more agreeable for administration, and also more effective ; but alum is cheap, and always to be obtained. Alum, dissolved in infusion or solution of the extract of logwood, is a useful injection in haemorrhage from the rectum, or as an applica- tion to bleeding piles, or as an astringent wash in prolapsus of the rec- tum in children. A crystal of alum, cut into a globular shape, may be passed into the rectum in such cases. The following ointment may be applied to haemorrhoids when they protrude, bleed, and are painful : ^ Pulv. aluminis, 3 ij ; pulv. camphorae, pulv. opii, aa 3 j ; unguent., |j. M. Sig.: Ointment. Notwithstanding the theoretical objections which have been made as to its utility, the use of alum is sanctioned by high authority in haemorrhages from distant organs of the body.

Alum was formerly used in diabetes mellitus, but more effective methods of treatment have taken its place. Good results have cer- tainly been produced by the use of alum in diabetes insipidus. Colli- quative siceats are moderated by the internal use of alum, and by sponging the surface with a solution. Alum has been used with a certain measure of success in whoop- ing-cough, during the spasmodic stage, but the more certain and pal- ALUM. 295 atable remedies now in our possession have quite displaced it. As an emetic in croup, there is no doubt of the utility of alum. It is used to cause the dislodgment of the false membrane, and to prevent its re-formation. It acts without depressing the bodily functions, is prompt and thorough. A teaspoonful of the powder, mixed with honey or sirup, may be given, and repeated every half -hour until free emesis occurs. External Uses of Alum. — A solution of alum in nitric ether is said to be an effective application in toothache ( 3 ij — 3 vij). When the gums are spongy and ill-conditioned, and manifest a tendency to recede from the teeth, the following local application is very service- able : 5, Aluminis, 3 j ; vini, Oj ; tinct. cinchonae, J ss ; tinct. myrrhae, 3 ij ; mel. rosae, f ij. M. Sig. : As a mouth-wash. When there is much relaxation of the faucial mucous membrane, alum and sugar, in equal proportions, may be applied by an insufflation-tube. Pow- dered alum, dusted over the affected surface, is a useful application in chronic pharyngitis, chronic tonsillitis, chronic nasal catarrh. Ul- cers of the mouth, whether syphilitic, or due to nursing, or arising from gastric disorder, are improved in character by application of a crystal of alum. A useful gargle in various affections of the mouth and throat is the following : ^ Infus. lini, § xv j tinct. kino, § j ; aluminis, 3 ij. M. Sig. : As a gargle. In catarrhal ophthalmia, after the acute symptoms have subsided, an alum-lotion is useful : r> Aluminis, 3 j ; aquae rosae, 3 iv. M. Sig. : Lotion. Alum-curd is a domestic application which is often ser- viceable : 3 ss of alum to the white of an egg.

Burned alum is a mild escha- rotic, which is sometimes used to destroy exuberant granulations. Authorities referred to : Gubler, Dr. A. Commeniaires de Thh'apeutique, etc., p. 433.

The vegetable alkaloids and gelatin form insoluble precipitates. Synergists. — Tonics and bitters, as a rule, favor the action of tannic and gallic acids, and of the substances containing them. The agents comprehended in this group — or remedies whose chief result is to increase waste — are synergistic. Physiological Actions. — Tannin has a bitter astringent taste, and constringes the mucous membrane. In the stomach it enters into com- bination with albumen, and with the pepsin of the gastric juice, which it precipitates from its solution. Tannin, therefore, impairs digestive power by rendering the pepsin inoperative. It diminishes secretion of the mucous membrane by virtue of its power to contract the caliber of the vessels, and it restrains peristalsis by its action on the muscular layer ; hence the constipating effects which follow its use. If long continued in considerable quantity, tannin disorders digestion, sets up irritation of the mucous membrane, and gives rise to a febrile state and to wasting of the tissues. Having such affinity for and coagulating action on albumen, it is obvious that tannin must diffuse into the blood with difficulty. A part undergoes conversion into gallic and pyrogallic acids in the stomach, and in this form is absorbed. Injected into the veins, tannic acid coagulates albumen, and the results which follow are due to mul- tiple embolisms. Elimination of tannin takes place by the intesti- nal canal and by the kidneys, in the form of gallic and pyrogallic acids. Therapy. — Catarrh of the stomach, a relaxed state of the mucous membrane, acidity, and flatulence, are conditions in which tannic acid is useful. It may be given in pill-form with sufficient glycerin to make a mass of proper consistence — one drop to four grains. Harnia- temesis dependent on ulcer of the stomach, or obstructive disease of the liver, and not inflammatory in origin, is an indication for tannin. It should be given in solution and in a large dose — grs. x — 3j. Tan- nic acid is an efficacious remedy in diarrhoea, after acute symptoms have subsided, in chronic diarrhoea, colliquative diarrhoea, the diarrhoea 300 AGENTS INCREASING WASTE. of phthisis, etc. Notwithstanding the chemical incompatibility, com- bination with opium or morphine increases the efficacy of the tannin. As tannic acid, in large part, at least, escapes conversion into gallic, and passes unchanged into the intestine, its action is doubtless chiefly local. Oppolzer advises the following formula in profuse diarrhoea : fy Acidi tanuici, 3 ij ; pulv. opii, grs. vj ; sacchari, q. s. M. Ft. pulv. no. vj. Sig. : One every two hours. In cholera diarrhoea, A. von Graefe prescribed a solution of tannic acid in cinnamon-water and mucilage every half -hour. For the diarrhoea and intestinal haemorrhage of ty- phoid fever, tannin is one of the most serviceable remedies. Accord- ing to Stille, whose faith appears rather extravagant, there is no more effective remedy for chronic diarrhoea and chronic dysentery than tan- nic acid conjoined with a milk-diet. Various members of this group are used in the above-mentioned diseases. Kino has been a favorite remedy in pyrosis, and is also given in diarrhoea! diseases. Catechu, in the form of the tincture chiefly, is frequently added to prescriptions for diarrhoea, notably to chalk-mixture in the diarrhoea of children. Kino is a favorite remedy for the diarrhoea of phthisis, but it is not more efficacious, and is more disagreeable in administration, than tannic acid. Several of the in- digenous remedies mentioned above possess undoubted value in the treatment of diarrhceal diseases. A decoction of rubus or geranium, obtained by boiling the root in milk ( 3 j — Oj), is an excellent remedy in cholera infantum and the summer diarrhoea of children. When a nursing child passes rather frequent, greenish, and watery stools, and suffers with pain and colic at each motion, great relief will be afforded by the use of syrupus rubi, or better by the unofficial compound sirup of rubus. In the chronic diarrhoea of adults, and in acute diarrhoea after the subsidence of inflammatory symptoms, the fluid extracts of hamamelis, of heuchera, and of statice, may be used with advantage. In hcematemesis and intestinal haemorrhage the hamamelis is very ef- fective, owing, doubtless, to the very large percentage of tannin which it contains. The comparative merits of tannic and gallic acids may be f ormu- larized as follows : for local effects tannic acid, for systemic effects gallic acid is to be preferred. It is true that tannic acid affects re- mote parts, but in order to diffuse into the blood it must first be con- verted into gallic, and hence the systemic actions are really due to the latter. It follows that gallic acid should be prescribed when the as- tringent effects on the tissues elsewhere than the intestinal canal are to be produced. Gallic acid is an effective remedy for pulmonary and renal hemorrhage. For the former we possess other agents more ef- ficient, but for the latter it is more uniformly successful than any other remedy. The success of rhatany, which was formerly much used in hematuria, was doubtless due to its tannic and gallic acids. In the TANNIC ACID AND VEGETABLE ASTRINGENTS. 301 hemorrhagic diathesis, gallic acid is one of the remedies which may be used with advantage. Although it can not be combined with chalyb- eates, it may be given alternately with them. "Whenever haemorrhage occurs in relaxed and debilitated constitutions — is passive in character — gallic acid may be combined with ergotine and digitalis : r> Acid, gallici, 3 i ; ergotine (aq. ex.), digitalis, aa 3j. M. Ft. pil. no. xx. Sig. : One every four hours. As gallic acid has the power to restrain secretion of mucous sur- faces, it may be prescribed, experience has shown with good effect, in chronic bronchial catarrh. When bronchiectasis exists, the good effects of the remedy are by no means conspicuous, but it is very serviceable when the bronchial catarrh is the result of the irritation extending from disease of the parenchyma of the lungs, or is produced by mitral or tricuspid regurgitation, or is the sequel of acute catarrh. In pyelitis and pyelo-nephritis, gallic acid and the remedies containing it diminish the purulent discharge, and retard changes in the mucous membrane. It is also a serviceable remedy in catarrh of the bladder. In these states, to insure as far as possible its rapid and complete diffusion into the blood, it should be given frequently and well diluted. As it is soluble in eight parts of rectified spirit, and as this solution mixes in all proportions with water without precipitation, a spirituous solution should be prescribed : $ Acidi gallici, 3 j ; spirit, vini rectif., \ j. M. Sig.: A teaspoonful in sufficient icater every four hours. Gallic acid has the power to restrain the waste of albumen in cases of albuminuria. It is adapted to the acute forms — desquamative ne- phritis, the albuminuria following scarlatina, etc., and does not seem, according to the author's observation, to check in the least the loss of albumen in the chronic forms of albuminuria. Dr. Aitken recommends the following formula : ^ Acidi gallici, 3 j — 3 ij ; acid, sulphuric, dil., 3 ss ; tinct. lupuli, 3 j ; infus. lupuli, f vj. M. Sig.: A tablespoonful three times a day. The following mixture is very effective in menorrhagia, hematu- ria, purpura hemorrhagica, and the hemorrhagic diathesis : t^ Acidi gallici, 3 ss ; acid, sulphur, dil., 3 j ; tinct. opii deod., 3 j ; inf. rosae comp., 3 iv. M. Sig. : A tablespoonful every four hours or oftener. Hillier advises the following prescription for chronic diarrhea in a child of two years : r£ Acidi gallici, gr. xij ; tinct. cinnamomi comp., 3 jss ; tincturae opii, m, viij ; aquae carui ad § ij. M. Sig.: Two tea- spoonfuls a dose. For the sweating of phthisis the following formula is useful : fy Acid, gallici, 3 ss ; ext. belladonnas, gr. ij. M. Ft. pil. no. x. Sig.: Two pUls at bed-hour. In addition to the foregoing internal applications of the vegetable astringents, it may be mentioned that a decoction of chestnut-leaves (castanea) has been used with much success in whooping-cough. As 302 AGENTS INCREASING WASTE. both tannic and gallic acids have been employed with more or less service in this disorder, it is probable that the good effects of castanea are really due to the presence in it of these acids. The decoction of castanea may be drunk ad libitum, or the fluid extract may be admin- istered in drachm-doses. External Uses of Tannic Acid and Substances containing it. — Dr. B. W. Richardson has proposed a tannin solution, to which he has applied the term styptic colloid. It consists of a saturated solution of tannin in alcohol (one part to eight) mixed with collodion. This is an elegant application to restrain oozing of blood from a large surface, to unite incised wounds, to protect lacerated wounds, to remove fetor from decomposing animal matter, to change the character of foul idcers, etc. The following formula was proposed by Monsel as a haemostatic : ^ Acidi tannici, 3 j ; aluminis, 3 ij ; aquae rosa?, § iij. M. Sig. : For external use as a haemostatic. The glycerite of tannin is a neat formula for external application. Tannic acid is much employed as an application to the mouth and throat in various diseases of these parts. In mercurial salivation an excellent application is a solution of tannin, with honey of roses : IJ Acidi tannici, 3 j ; mel rosae, § ij ; aquae, § vj. M. Sig.: As a gargle. Elongated uvula, relaxed palate, and follicidar pharyngitis, are effec- tively treated by insufflation of tannin, i. e., some finely-powdered tan- nin blown over the affected surface with a hand-ball insufflator. Epis- taxis may often be promptly arrested by passing through the nares a strong solution of tannin ( 3 ij — 1 iv) by means of a post-nasal syringe or nasal douche, or powdered tannin may be blown on the bleeding surface by an insufflator. The following is an excellent gargle for the more chronic throat-affections : fy Acidi tannici, 3 ij ; spts. vini rect., 3 j ; mist, camphor, ad § x. M. Sig. : An astringent gargle. In chronic affections of the larynx mucous membrane, and of the vocal cords, no inhalation is more frequently serviceable than a solution of tannin (grs. x — 3] — ? iv) applied by means of the hand-ball or steam atomizer. This treatment is useful in chronic catarrh of the fauces, of the larynx, trachea, and bronchi, in ulcerations of the pharynx, larynx, and trachea, in bronchiectasis, in pulmonary haemor- rhage, gangrene of the lung, oedema of the glottis, croup, and diph- theria. The following is Druitt's prescription for toothache : 3 Acidi tan- nici, 3j ; mastich, grs. x ; etheris, § ss. M. Sig. : To be applied on cotton to a carious tooth. Tannin solutions of various strengths (gr. j — grs. x — 3 j) are used in inflammation of the conjunctiva. Hairion advises a strong solution ( 3 j — 3 iij) in acute and chronic conjunctivitis, gramdations, corneitis, chemosis, and pannus. Very remarkable results have been obtained by Dr. Hamilton, of Liverpool, in certain diseases of the eye by the TANNIC ACID AND VEGETABLE ASTRINGENTS. 303 application of powdered tannin to the conjunctiva. This method con- sists in dusting over the everted lid finely-powdered tannic acid, using for this purpose a small rubber-bag insufflator. He employs this method with signal success in " granular ophthalmia, pannus, phlyctenular or pustular ophthalmia, chronic granulations, herpes corneas, fascicular corneitis, and some ulcers of the cornea." This application produces very little pain at the moment, and is not followed by any inflamma- tory reaction. Tannic acid has limited uses in diseases of the skin. It is an excel- lent application, especially in the form of the glycerite, in eczema, im- petigo, and intertrigo. The powder dusted on the affected surface is serviceable in cases of ulceration of the skin, and promotes the healing process in cases of old ulcers. One of the best applications to irritable and fissured nipples is glycerite of tannin. Chronic otorrhoea and the vulvitis of children are successfully treated by application of the glycerite of tannin. The same remedy is one of the best injections in gonorrhoea. Solutions of tannic acid of various degrees are used in gonorrhoea. Ricord recommends, in obsti- nate cases, after the subsidence of acute symptoms, 3 ss of tannic acid in | viij of claret wine. This constitutes a serviceable injection in leu- corrhoea. Sigmund advises the following in gonorrhoea : fy Acidi tan- nici, grs. ij — grs. x ; tinct. iodinii, m v ; aquae, § j. M. Sig. : As an injection. An infusion or decoction of galls, of oak-bark, of witch- hazel (hamamelis), of geranium, of alum-root, or other remedies of the list at the head of this article, may be advantageously used in cervicitis, vaginitis, purulent discharges from the vagina. In these affections the glycerite of tannin, and, much better, the powdered tannin, may be freely applied to the vaginal canal. The author knows of no more effective application in these maladies than tannin and iodoform, or iodo- tannin, applied in the dry way, well packed around the cervix uteri. A serviceable ointment for haemorrhoids is the following prescrip- tion of Oesterlen : I£ Pulv. gallse, 3 j ; pulv. opii, grs. x ; ung. plumbi subacetat., 3ij ; ung. simplicis, 3 j. M. Sig. : Ointment for haemor- rhoids. F 'or prolapsus ani in children the glycerite of tannin, pow- dered tannin, or a decoction of the vegetable astringents considered in this article, may be used, the mucous membrane being first carefully cleansed and then brushed over with the medicament. Ulcers of the rectum and anus, fissures of the anus, are very effectively treated by the direct application of the powder of tannin, tannin and iodoform, or iodo-tannin. The ulcer must be exposed, if necessary, by the use of the speculum, and then the powder be thoroughly applied to the affected surface. Trousseau strongly recommends a mixture of the decoction and the tincture of rhatany as an injection for the cure of fissure of the anus, but the applications above advised are neater and more effective. 304 AGENTS INCREASING WASTE.

Fifteen parts of the seed to one hundred parts of stronger white wine. Dose, in, x -3j. Composition. — Tannic and gallic acids, starch, sugar, gum, a pe- culiar alkaloid, colchicine^ or colchicine. Colchicine is easily converted (by acids, in long-kept alcoholic preparations) into an isomeric, crys- tallizable body, colchicein. The amount of the alkaloid contained in the root and the seed is said to be not greater than the half of one per cent. Colchicine is not crystallizable, but combines with acids to form COLCHICUM. 305 crystallizable salts. The conversion, in any of the pharmaceutical preparations, of colchicine into colchicein, does not appear to impair the therapeutical activity. That colchicine is the active principle, is proved by the fact that the physiological effects of this alkaloid are the same as those of the crude drug (Husemann). Antagonists and Incompatibles. — Tannic acid, by forming an insoluble tannate with the alkaloid, retards but does not prevent its absorption. When a lethal quantity has been taken, emetics and pur- gatives are required, and demulcents may be freely administered. Opium and the alcoholic substances antagonize the depression of the heart's action. Synergists. — Such alkaloids as produce gastro-intestinal irritation and depress the action of the heart, e. g., veratrine, aconitine, etc., are synergistic. Therapeutically considered, emetics, purgatives, alkalies, promote the activity of colchicum. Physiological Actions. — Colchicum imparts its virtues to water, alcohol, and ether. It has a bitter taste, and excites the flow of saliva. In small doses it increases the mucous and glandular secretion of the stomach and intestines, and probably also of the liver, kidneys, and skin. If the dose be large but still medicinal, colchicum produces a feeling of epigastric heat, nausea, and vomiting, depression of the cir- culation, muscular feebleness, headache. It frequently purges, pro- ducing copious watery stools, and is generally held to increase the discharge of biliary matters. It increases the flow of urine, of the solid constituents (urea, uric acid, etc.), as well as of the water, and promotes the cutaneous transpiration. In toxic doses colchicum pro- duces all of the local as well as the systemic effects of an irritant poison, viz. : acute abdominal pain, profuse watery and choleriform dis- charges, suppression of urine, feeble pulse, cold sweat, coldness of the extremities. The intellect remains unaffected until carbonic-acid poi- soning supervenes. The muscular cramps which have been occasionally observed are probably due to the great loss of fluid from the system. When colchicine is injected subcutaneously, gastro-intestinal inflamma- tion is produced, showing that it has a selective action on this tissue. Therapy. — Colchicum is indicated when rapid wasting of tissue and prompt elimination of the products of waste are required. Its use at the present time is almost entirely restricted to the treatment of gout in its various manifestations. It relieves the pain, diminishes the swelling, and shortens the duration of an attack of acute gout. In order to accomplish these results, it is not necessary that the more harsh and violent physiological effects of the drug be produced. Suf- ficient quantity of colchicum should be given to increase secretion from the skin, the intestinal mucous membrane, and the kidneys, but nausea and vomiting should be avoided. Combination with an alkali increases the therapeutical effect of colchicum : I> Spts. ammonias aromat., 3 xiij ; 20 306 AGENTS INCREASING WASTE. vini seminis colchici, 3 iij. M. Sig. : A teaspoonful every three hours, until some physiological effect is produced. The following is a formula used at the London Hospital for gout : fy Tinct. colchici seminis, ttj, xx ; potassii bicarbonat., grs. x ; aquae pimentae, | j. M. Sig. : A draught.

I£ Colchicine, gr. j ; ext. colocynth. comp., 3 ss ; quininae sulph., 3 iij. M. Ft. pil. no. lx. Sig. : One every four hours. In the so-called rheumatic gout, colchicum with alkalies is extreme- ly serviceable. Attacks, without decided pain and inflammation, of soreness of joints, which have been the seat of gouty attacks, or about which nodosities have been deposited, are relieved by colchicum. Constipation, hepatic congestion, and headache, due to torpor of the portal circulation, occurring in gouty subjects, are quickly relieved by a combination of colchicum and saline purgatives. The plethoric and overfed without being gouty, suffering from the same group of symptoms, are relieved by the same means, Inflammations of internal organs occurring in gouty subjects, for example, gouty bronchitis and rheumatic pneumonia, are best treated with prescriptions containing a preparation of colchicum. The following prescription is recom- mended by Greenhow in gouty bronchitis : ^ Potassii iodidi, ammonii carbonat., aa 3j ; vin. colchici seminis, 3 j ; tinct. scillae, tinct. hyos- cyami, aa 3 ij ; aquae c amphorae q. s. ad § iij. M. Sig. : A table- spoonful three times a day. Although colchicum is still advocated by some authorities in acute rheumatism, the general professional experience is against its use. In chronic rheumatism, when the joint changes are allied in nature to those which take place in gout, it is unquestionably serviceable. Neu- ralgia occurring in gouty and rheumatic constitutions is often relieved by colchicum. The indications for its use are plethora, constipation, and deficient excretion of the liver, kidneys, and skin. Colchicum re- lieves in such cases, by setting up an eliminative process. In hepatic dropsy and cardiac dropsy, when the patient is vigorous, the gastro- intestinal tract free from inflammatory mischief, colchicum may be SARSAPARILLA. 307 used with advantage as a hydragogue : 3 Elaterii, gr. j ; spts. etheris nitre-si, § ij ; tinct. scillae, tinct. colchici, aa § ss ; syrup, simplicis, § j.

This prescription is well adapted to dropsy following scarlatina. Colchicum is a serviceable remedy in certain cerebral disorders. Thus, it may be used in acute cerebral congestion in plethoric subjects, in urmmic intoxication, in hypochondriasis, especially when due to deficient elimination (uric acid, oxalate of lime, etc.). The wine of colchicum-seed has frequently succeeded in curing gonorrhoea, and by Brodie a nightly dose of thirty minims was given for the relief of chordee. In the treatment of gonorrhoea, the follow- ing may be used : ££ Vini colchici seminis, § ss ; sol. potassii citratis, 1 vjss ; tinct. opii deod., 3 ij. M.

Antagonists and Incompatibles. — Alkalies favor the decomposi- tion of the decoction and fluid extracts. As there is much starch pres- ent in the drug, free iodine should not be prescribed with the official preparations. Synergists. — Iodine, mercury, and other so-called alteratives, in- crease the therapeutical activity of sarsaparilla. Warm clothing in- creases the action on the skin ; diluents favor increased urinary dis- charge. Physiological Actions. — Much discrepancy obtains in the opin- ions which have been emitted in respect to the physiological actions of sarsaparilla. Surgeons generally hold to its therapeutical powers ; physicians are skeptical. The physiological experiments which have been made, both with the preparations of the crude drug and with the alkaloid, have yielded negative results. Palotta's experiments, made with the alkaloid which he had discovered so long ago as 1825, indicate that eight grains of the alkaloid produce gastric disturbance, vomiting, slowing of the pulse, depression, faintness, and sweating. These re- sults have since been in part confirmed by Cullerier. Boecker, how- ever, making more systematic examination in accordance with modern methods, finds that sarsaparilla is devoid of physiological activity and of therapeutical power (Husemann). Therapy. — From the point of view of the physiological experi- ments it is not difficult to understand the modern incredulity in regard to the curative power of sarsaparilla. .The difficulty of distinguishing between the post hoc and the propter hoc serves to account for the belief still held in some quarters, that this drug is an alterative. Pop- ularly, sarsaparilla is supposed to have extraordinary powers as a " blood-purifier," and its large use at the present time arises from this belief. Almost the only use of sarsaparilla at the present time is in the treatment of syphilis. It is, of course, not adapted to the primary or to the secondary forms. The experience in its favor, even of those most confident of its powers, restricts its use to the tertiary form in debilitated subjects, who have been broken down by the combined in- fluence of syphilis, mercurialism, and iodism. It has been further dem- onstrated that the best effects have been obtained by the use of large doses of the compound decoction (Allbutt). As the compound decoc- tion contains guaiac and mezereon, it is difficult to assign the exact share of the sarsaparilla in the result. Furthermore, as a pint or more of the compound decoction must be taken in the twenty-four hours, these large draughts of a warm liquid are not without influence on the GUAIACUM. 309 functions of the skin and kidneys. It is extremely questionable whether sarsaparilla has any therapeutic power ; it is not at all equal us an alterative to some of the remedies indigenous in the United States, to be considered hereafter. The compound fluid extract, the compound decoction, and the compound sirup of sarsaparilla, are frequently used as vehicles for iodide of potassium and for the bichloride of mercury in secondary and tertiary syphilis. Scrofula, chronic abscesses, necrosis of bones, old ulcers, and stru- mous cutaneous affections, are diseases in which sarsaparilla is sup- posed to be efficacious. It is more used as an adjunct to more active remedies than depended on alone. Authorities referred to : Allbutt, Dr. Clifford. TJie Practitioner, 1870, vol. i. Gcbler, Dr. Adolphe.

Synergists. — Agents which promote cutaneous activity are syner- gistic. The action of guaiac is much aided by external warmth and warm diluent drinks. Physiological Effects. — Guaiac has a very acid and pungent taste. It excites an abundant flow of saliva. In the stomach it cre- ates a sensation of warmth and burning, increases the secretions of the gastro-intestinal canal, accelerates the action of the heart, promotes diaphoresis, and favors the production and excretion of bronchial mu- cus. In large doses it deranges digestion and causes gastric catarrh, and in excessive doses the series of symptoms produced by the irritant poisons, vomiting, purging, cramps, headache, giddiness, etc. 310 AGENTS INCREASING WASTE. Therapy. — Formerly guaiac was in great repute as a remedy for constitutional syphilis. The decoction was drunk in large quantity, a very spare diet was enjoined, and the diaphoretic action of the rem- edy was aided by external warmth. Doubtless many cases were bene- fited by this mode of treatment, but the result was probably less due to guaiac per se than to the regimen. Its present use as an anti-syphilitic remedy is confined to the prep- arations of sarsaparilla, in which it enters as a constituent. Recent clinical experience has shown that guaiac is a capital rem- edy in tonsillitis. Given in a half-drachm dose (tincture) every four hours, it appears to abate the inflammation and to cut short the dis- ease in a remarkable manner. It is a very acrid and disagreeable rem- edy, and should be given in emulsion, with mucilage or yolk of egg, Guaiac is a useful remedy in dysmenorrhea, when the pain is due to rheumatism or neuralgia, and is of course not adapted to those cases in which there is narrowing of the cervical canal. Lastly, guaiac is used with varying degrees of success in chronic gout, chronic rheumatism, lumbago, sciatica, gouty bronchitis, etc. As we have so many more efficient and pleasant remedies for these dis- eases, it will rarely be necessary to resort to guaiac.

A tincture may be made of two ounces of the bruised root to a pint of diluted alcohol, of which the dose is 3 ss — 3 ij. A decoction may be made as follows : one ounce of the bruised root to two pints of water, boiled down to one pint, of which the dose is § ss — § ij. All the preparations should be made of the fresh root, as the activity of the drug is diminished by drying.) Composition. — The plant yields on incision a milky juice, which appears to possess the medicinal properties of the drug. The so-called stillingin of the eclectics is not the active principle, but an extract. The active principle has not yet been isolated. Physiological Effects. — The juice of the plant has an acrid, pun- gent taste, leaving a persistent after-taste of great activity. It excites an abundant flow of saliva. In the stomach a feeling of warmth fol- lows its use, and the secretions of the organ are increased in amount. In full doses it excites nausea and vomiting, epigastric pain, and an STILLINGIA. 311 acrid, burning sensation in the fauces. It increases the secretions of the intestinal canal, notably of the liver, and, in full doses, purges, the fseces having the appearance of the so-called "bilious stools." In- creased action of the heart follows the introduction of the active prin- ciple into the circulation, and the skin becomes warm and moist. The bronchial mucous membrane exhales a larger quantity of mucus, and the kidneys become more active, excreting an increased quantity of wa- ter and solids. It may, therefore, with propriety be grouped with the so-called alteratives. Therapy. — Stillingia is certainly a very valuable remedy. It has long had a local reputation in the Southern Atlantic States as an al- terative. In habitual constipation, due to deficient secretion of the intestinal mucous membrane, it may be used with advantage. The torpidity of the liver and jaundice, which follow attacks of intermittent fever, are removed by stillingia. This agent also renders important service in the first stage of cirrhosis, and in ascites due to the hepatic changes. Hemorrhoids, when produced by obstructive difficulty in the liver, may be removed temporarily, and, if due to constipation, may be re- moved permanently, by stillingia. In habitual constipation the following formula is useful : Ijt Ext. stillingise fl., 3 v ; tinct. belladonna? ; tinct. nucis vom. ; tinct. physostig- matis, aa 3 j. M. Sig. : Twenty drops, in water, three times a day be- fore meals. When the biliary secretion is deficient, the following : I£ Ext. stillingia? fl., 3 v ; tinct. aloes, 3 ij ; tinct. nucis vom., 3 j. M. Sig. : Twenty drops, in water, three times a day. Stillingia has long been in popular repute as an alterative, and em- ployed in domestic practice as a remedy for scrofula in its various forms. The success which has attended its employment in some de- gree justifies the high encomiums which have been bestowed on it. It is very serviceable in children who present the following symptoms : enlarged cervical glands, mucopurulent discharge from the nose, with excoriations of the surrounding integument, a pasty complexion, ca- pricious and unnatural appetite, tumid abdomen, whitish and pasty stools j dull-red, soft, and tubercular eruption on the shin, ulcerating and furnishing a large quantity of unhealthy pus. The steady use of stillingia, combined with suitable hygienic means, will accomplish important relief in such cases*. The most satisfactory results have been obtained from the use of stillingia in syphilitic affections. It is applicable to the same condi- tions under which the preparations of sarsaparilla are now used, viz., in chronic cases of the secondary and tertiary form, the patients hav- ing been broken down by the long-continued use of mercurials and iodides. Repeated observation of cases in which it was used as the sole agent has satisfied me of its curative value. It differs from the 312 AGENTS INCREASING WASTE. compound decoction of sarsaparilla in this, that its effect is distinctive, and is not due to the use merely of a large quantity of fluid. The eminent Dr. Porcher, of South Carolina, thus expresses himself with regard to the use of stillingia in syphilitic affections : " I have em- ployed the decoction of the root of this plant as an alterative in syphi- litic sores, occurring in patients in the City Hospital, Charleston, the spread of which nothing else could arrest. It proved completely satis- factory. Phagedenic chancres were rapidly cured under its use. A strong decoction was given three times a day, with four drops of nitric acid to each dose." A strong infusion or decoction of stillingia is said to be effective in preventing the development of a paroxysm of ague, if taken before or just as the chill is beginning. It is reported that profuse diaphoresis is produced and the impending attack is averted. The fluid extract of stillingia may be given in combination with quinine or arsenic in intermittents. • Authorities referred to : Porcher, Dr. Francis Petre.

Dose, tti v — 3 ss. Extractum Sanguinariaz Fluidum. — Fluid extract of sanguinaria. Dose, t\[ ij — ill, xx. Composition. — Sanguinaria contains an alkaloid, sanguinarine, which appears to be identical with the ehelerythrine of Probst. San- guinarine is a white, pearly substance of an acrid taste, very sparingly soluble in water, soluble in ether, and very soluble in alcohol. With the acids it forms salts soluble in water, all of which have some shade of red, crimson, or scarlet, and form beautiful red solutions. Another alkaloid, named porp>hyroxine (sanguinaria-porphyroxin — Husemann), has been found by Riegel. Besides these alkaloids, sanguinaria con- tains a peculiar acid, chelidonic, and another has been announced, for which the name sanguinarinic acid has been proposed, but this latter acid has been shown to be a mixture of malic and citric acids. The alkaloids exist in the root in combination with these acids — the most important compound being the chelidonate of sanguinarine. Besides the foregoing, blood-root contains the following unimportant constitu- ents : resin, gum, extractive, albumen, sugar, etc. SANGUINARIA. 313 Antagonists and Incompatibles. — Alkalies, tannic and gallic acids, and most of the metallic salts, are chemically incompatible with the preparations of blood-root. The local irritant action of the drug and the depression of the circulation which it causes are antagonized by opium, by amyl nitrite, by atropine, etc. Synergists. — The mineral and vegetable emetics, the so-called alteratives of the vegetable kingdom, and the mineral salts, considered from the therapeutical point of view, promote the physiological and therapeutical effects of sanguinaria. Physiological Effects. — Sanguinaria has a bitter, acrid taste, which persists for a long time. When swallowed, it leaves a sense of constriction and acridity in the throat. It excites a feeling of heat in the stomach, and stimulates secretion of the mucous membrane. If the quantity taken is insufficient to produce nausea, the action of the heart is increased, and a subjective sensation of warmth is experienced throughout the system. In considerable doses sanguinaria is an active emetic, producing much nausea and depression, and slowing the action of the heart. It is very irritating to the mucous membrane. Snuffed up the nose, it produces violent sneezing. In large doses it inflames the stomach, producing intense burning, with thirst, great prostration, dimness of vision, vertigo, and collapse. The alkaloid, sanguinarine, manifests all the physiological capa- bilities of the drug. It has an intensely bitter, acrid taste. In small doses (one twelfth to one eighth of a grain) it simply increases secre- tion of the gastro-intestinal mucous membrane ; in doses of one sixth to one fourth of a grain it causes depressing nausea and sometimes vomiting. In large doses it produces, in addition to the gastric symp- toms mentioned above, slowing and irregularity of the pulse, cold sweats, cold extremities, vertigo, dilated pupils, anxiety, etc. Applied to fungous granulations, sanguinaria has considerable es- charotic power. The sketch above given of the physiological actions of sanguinaria, which embodies the results of the author's investigations and clinical studies, requires no special modification. The recent elaborate and most thorough research of Dr. Robert Meade Smith confirms the author's account. The reader who wishes to exhaust the subject will find that nothing has been omitted by Dr. Smith. Therapy. — In atonic dyspepsia from two to five drops of the tinc- ture, or the one twelfth of a grain of sanguinarine, may be used with advantage. It promotes secretion, and increases the appetite. There seems no doubt, according to the author's observation, that sanguinaria promotes the hepatic and intestinal secretions. It is, therefore, a ser- viceable remedy in duodenal catarrh, and secondary catarrh of the biliary ducts with jaundice. Its most important therapeutical effects are witnessed in diseases of 314 AGENTS INCREASING WASTE. the respiratory organs. Chronic nasal catarrh is successfully treated by the internal use of the tincture (ten drops ter die), or of the alkaloid (one fifteenth of a grain ter die), and the local application of the pow- der, in small quantity, applied by an insufflator to the Schneiderian mucous membrane. In acute bronchitis (catarrh), after the subsidence of the more acute symptoms, it is a serviceable expectorant. It may be combined with other expectorants and alterants : fy Tinct. sangui- naria?, 3 j ; tinct. lobelia, 3 j ; vini ipecac, 3 ij ; syrup, tolutan., § ss. M. Sig. : A teaspoonful every three hours as an expectorant. In humid asthma the following combination is extremely serviceable : Tfr Tinct. sanguinaria?, 3 j ; tinct. lobelia?, 3 j ; ammonii iodidi, 3 j ; syrup, tolutan., 3 vj. M. Sig. : A teaspoonful every two, three, or four hours. In spasmodic asthma the same prescription is occasionally very effect- ual, but the author is unable to indicate the precise condition under which it is most useful. Sanguinaria has been proposed as an emetic in croup. It is, how- ever, too uncertain in action, and too harsh, to justify its use when there are so much more eligible remedies at hand. The emmenagogue properties of sanguinaria seem well established. It is indicated when amenorrhcea is functional in character, when there is an absence of plethora, and when no malformation exists. It may be advantageously combined with aloes, provided there is no con- traindication to the use of the latter. $ Tinct. sanguinaria?, 3 ij ; tinct. aloes, § ss ; tinct. nucis vom., 3 ij. M.

Sig. : Fifteen to twenty drops, in water, three times a day. As an alterant in chronic syphilitic and strumous affections, san- guinarine may be used in the same class of cases as sarsaparilla, guaiac, and stillingia. It is an important addition to a decoction of woods in- digenous to our soil, used as a substitute for the more expensive and really less efficient foreign drugs of the same group. Local Applications. — Sanguinaria, having feeble escharotic prop- erty, is used as a local application to repress exuberant granulations, and to ill-conditioned ulcers to change their character. Several cases have been reported, indicating the power of sanguinaria to repress the growth and destroy nasal polypi.

Xanthoxylum. — Prickly ash. The bark of Xanthoxylum fraxi- neum Willdenow and of X. carolinianum Lambert (Nat. Ord. Ruta- cece, Xanthoxylem). Extr actum Xanthoxyll Fluidum. — Fluid extract of xanthoxylum. Dose, in x — 3 j. A decoction may be made by boiling an ounce of the bark in a quart of water down to one pint, and of this one to two ounces may be used every four hours. A tincture may also be prepared with two ounces of the root to a pint of diluted alcohol, of which the dose would be 3 ss — 3 ij. The official fluid extract is more frequently in use ; the dose of this is xn, xv — 3 ij. Composition. — Xanthoxylum contains a neutral crystallizable prin- ciple, which is known as xanthoxylin, and is said to be identical with xanthopicrite, and the latter has been shown to be berberine. Besides this important constituent, a volatile and a fixed oil, resin, gum, etc., are contained in it. Physiological Actions. — The taste of xanthoxylum is at first sweetish, and somewhat aromatic, but considerable bitterness is soon developed, followed by acridity, which remains long in the fauces. It has remarkable sialagogue property, and the increased flow of saliva occurs from the systemic effects, as well as from the local impression on the mucous membrane of the mouth. In the stomach it excites a sensation of warmth, and increases secretion from the stomach and in- testinal mucous membrane. It is in a high degree probable that just as its presence in the mouth causes salivation, so its presence in the intestinal canal determines the flow of gastric, duodenal, hepatic, and pancreatic secretion. The action of the heart is increased by xan- thoxylin, the arterial tension rises, the capillary circulation becomes more energetic, and the sweat-glands are made to pour forth a more abundant secretion. Corresponding effects are produced in the kid- neys, and increased flow of urine follows its administration. Therapy. — Xanthoxylum is a domestic remedy for toothache. The bark, chewed, has a popular reputation for paralysis of the tongue. A decoction of the bark is an efficient local application to the throat when, 316 AGENTS INCREASING WASTE. in cases of chronic pharyngitis, there is dryness of the mucous mem- brane. From ten to thirty minims of the fluid extract, or a half to one drachm of the tincture, ter in die, is a successful remedy for an ex- tremely obstinate affection, namely, chronic pharyngitis — the mucus adhering in large, thin, dry scales, and the mucous membrane being glossy, shining, glazed, and dry. The active principle (xanthoxylin) is a useful stomachic tonic in atonic dyspepsia. When, however, in stomach, intestinal, or hepatic disorders the object is to promote secretion, the preparations of xan- thoxylum must be used. Jaundice due to catarrh of the bile-ducts, and that form of jaundice produced by acute malarial poisoning, are con- ditions in which xanthoxylum is distinctly remedial. Constipation, due to deficient secretion, is also removed by this agent. Xanthoxylum has long had a deserved reputation in the treatment of chronic rheumatism. It is adapted to muscular rheumatism, myal- gia, and such local muscular disorders as torticollis (recent cases), lum- bago, etc. It may be used with advantage, locally, in these affec- tions. The curative power which it possesses in chronic rheumatism is doubtless due to its eliminant action on the mucous and cutaneous surfaces. Xanthoxylum is a remedy for constitutional syphilis of equal merit with guaiac, mezereon, stillingia, etc., and is greatly more effective than sarsaparilla. Decoction of xanthoxylum has been used with success in the treat- ment of dropsy. Fraxinus Americana. — The inner bark of the root. (Not official.) Preparation. — Vinum Fraxini. The inner bark of the root col- lected in November, eight ounces ; stronger white wine, or sherry, two pints. The root-bark should be macerated in the wine three or four days ; after percolation, to every 25 parts there should be added 2 parts of glycerin and 1 part of alcohol. The dose of the wine thus prepared is a teaspoonful or two, three times a day, before meals. Actions and Uses. — There has been no adequate study of the physiological actions of fraxinus. Its employment is, thus far, merely empirical. We owe to Dr. Charles P. Turner, of Philadelphia, the knowledge now in our possession regarding its therapeutical powers. It belongs to the group of alterative medicines, if we may still use this rather obsolete term. Administered in certain diseases, it modifies the local morbid process, or cures it without any recognizable disturbance of the functions. The chief use of it thus far has been in the treat- ment of certain uterine disorders. Dr. Turner has found it to have a curative action in chronic metritis, and in the disorders consequent on this condition of the uterus. In the various forms of dysmenorrhoea, especially the congestive variety, it has proved to be very effective. Lest disappointment may be experienced from its use, we assure our ANTISEPTICS. 317 readers that the administration of the wine must be kept up for several weeks or months. When administered for dysmenorrhoea, it should be taken diligently in the interval, and when given for metritis, it should be taken assiduously for several months.

AGENTS HAVING THE POWER TO ARREST SEPTIC PROCESSES, AND TO DESTROY THE FERMENTS OR THE MINUTE ORGANISMS (DISEASE-GERMS), ON THE PRESENCE OF WHICH THEIR ACTIVITY DEPENDS. ANTISEPTICS. Those remedies are entitled antiseptic which are employed to ar- rest fermentative processes. It is now generally admitted that every kind of fermentation is correlative of the growth and multiplication of a living organism. In various diseases, microzymes, vibrio, bac- teria, either stand in a causative relation to the morbid process, or are necessary to its evolution and development. As an exemplification of the influence exerted by these minute organisms in diseased states, I may mention the bacteria of Oertel, which are formed in such immense numbers, and attain to such wide diffusion in diphtheria ; the protomy- cetes of Obermeier, which play so important a role in relapsing fever ; the bacillus malarise of Klebs and Tomassi-Crudeli; the bacillus tubercu- losis of Koch, and the specific bacteria (cacobacteria) found by Burdon- Sanderson in the exudation of septic inflammation of the peritonseum. Disease-germs, which may not exist in definitely-organized forms, are, at least, constituted of living matter, having properties apparently similar to those ferments with which chemistry has made us acquainted. Increased importance is given to the subject of ferments, by the dis- covery of ptomaines — alkaloidal substances found in the body after death — and by those poisons generated in the course of the septic dis- eases which have, apparently, a similar genesis. Although for many specific and communicable diseases the pathogenetic germs remain un- known, sufficient facts have been collected to justify the theory of the existence of such organisms. The remedies of this group — antiseptica — have the power, when brought into contact with the minute organisms or disease-germs men- tioned above, to destroy their vitality, and to arrest the fermentation process, or zymosis, which they either initiate or promote. There is a distinct relation between the antiseptic and antipyretic properties of 318 ANTISEPTICS. various members of this group, and they have the power to depress temperature in the same ratio that they are active in destroying dis- ease ferments and germs. Some of these remedies, e. g., quinine, sul- phurous acid, the sulphites, etc., have already been discussed in Part II. Under this head there remain for consideration several important agents whose applications are distinctly antiseptic. Oxygenium.— Oxygen. Oxyglne, Fr.; Sauerstoff, Ger. (Not official.) Preparation.— The most convenient mode of preparing oxygen for medical purposes is to heat in a gun-barrel-shaped brass or iron re- tort a mixture composed of five parts of chlorate of potassium and one part of binoxide of manganese. When heated to dull red, the chlorate yields up its oxygen, being reduced to chloride. The gas may be most conveniently collected over water, which dissolves but little of the oxygen, but takes up all the chlorine that may be accidentally present. It is a permanent, elastic gas, inodorous, without taste, incombus- tible, but uniting with bodies in a state of combustion. It is very slightly soluble in water at the ordinary temperature and pressure. Dose. — The quantity of oxygen which may be inhaled, in the or- dinary medicinal applications of this gas, ranges from one to five gal- lons. The simplest apparatus will suffice, but an elastic bag, with a suitable mouth-piece, is usually employed for this purpose. Physiological Actions. — If the important role which oxygen plays in the economy of Nature furnished a measure of its powers when administered as a remedy, it would be a most important thera- peutic agent. When inhaled in the pure state (not as air), it produces singularly little constitutional disturbance. A sensation of warmth in the larynx, trachea, and bronchi, is first experienced ; the pulse, as a rule, somewhat increases, though it may be lessened in frequency ; a sense of mental exhilaration and a disposition to greater bodily activity are produced ; the appetite becomes keener ; but no constant influ- ence on the excretions has been noted (Demarquay). Experiments on animals have demonstrated that the inhalation of oxygen per se does not have an injurious effect on animal life (A. H. Smith). On the contrary, as Hayem has recently shown, the administration of oxygen in from forty to ninety litres per day, given in two doses and mixed with a determinate quantity of air, energizes to a considerable degree the nutritive functions ; it increases the appetite, slightly ele- vates the temperature, stimulates the cardiac movements, and aug- ments the body-weight. These results are due in the main to the ef- fect of oxygen on the blood ; it increases the number and stimulates the organic activity of the red blood-globules. Although this action is not constant, the effects may become so by the greater nutritional changes which are thus promoted. When the inhalations are sus- OXYGEX. 319 pended, these effects on the blood cease. Anne's results, obtained by a course of experiment on himself, entirely confirm those obtained by Hayem. Therapy. — Oxygen is indicated and has been used with success in diseases of the respiratory organs, characterized by dyspnoea, due to causes interfering with the oxygenation of the blood, in emphysema, asthma, croup, asphyxia, chloroform narcosis, asphyxia from toxic gases, etc. In these cases oxygen acts in a manner which is perfectly obvious : the labor of breathing and the damage to the respiratory center are lessened by the addition to the blood of oxygen in larger quan- tity than is supplied by the air. In these cases, pure oxygen, or a mix- ture of one part of the gas to two or three of air, may be employed. The more extreme the dyspnoea, the greater the necessity for undi- luted oxygen. Oxygen is also indicated, and has been successfully employed, in certain diseases characterized by insufficient oxidation : chlorosis, ance- mia, leucocythemia, diabetes, albuminuria, etc. In such cases the in- ternal administration of chalybeate medicines, or mineral waters, should accompany the inhalations of oxygen. Pure oxygen is not ne- cessary ; an admixture with three parts of air will suffice, and the inhalation should be made morning and evening. The evidence is satisfactory that oxygen-inhalations produce good results in some cases of phthisis. Those cases appear to be most bene- fited in which emaciation, dyspeptic symptoms, etc., have occurred, without marked change in the condition of the lungs. When hectic fever comes on, and excavations have occurred, the utility of oxygen has ended, except as a palliative of dyspnoea. Pinard reports a case of vomiting of pregnancy, uncontrollable by other means, promptly arrested by oxygen inhalations. Hayem gives similar facts, and also reports the good effects of this remedy in gastralgia, dyspepsia, and other functional disorders of the stomach. In cancer, chronic catarrh, and dilatation of the stomach, it affords relief without having a cura- tive action. Authorities referred to : Andrews, Dr. J. B.

Chlore, Fr. ; Chlor, Ger. (Not official.) Properties. — Chlorine is a greenish-colored gas, of a persistent, penetrating, suffocating, and characteristic odor. It is soluble in water in the proportion of two volumes (of gas) to one. Aqua Chlori. — Chlorine-water is a greenish-yellow liquid, possess- ing the suffocating odor of chlorine. Liquor Sodw Chloratce. — Solution of chlorinated soda. A trans- parent liquid, of a greenish-yellow color, having a slight odor of chlo- rine, a sharp, saline taste, and an alkaline reaction. Calx Chlorata. — Chlorinated lime. Chloride of lime. A grayish- white substance, in powder or friable lumps, dry or but slightly moist, and nearly entirely dissolved by dilute muriatic acid, with the escape of chlorine. It should contain at least 25 per cent of chlorine. Physiological Actions. — Chlorine as a gas, or in solution in wa- ter, is an active irritant. Applied to the skin for some minutes, it causes heat and burning, increased diaphoresis, and, if the contact be sufficiently prolonged, vesication. Inhaled in very small quantity, largely diluted with air, this gas induces a sensation of warmth in the chest, and increases the bronchial mucus. In considerable quantity it is a violent irritant, excites spasm of the glottis, and sets up active inflammation of the larynx, bronchi, and lungs. Chlorine is without action when moisture is not present. Water is decomposed by it, chlorhydric acid is formed, and oxygen set free as active oxygen or ozone. The antiseptic and antiferment properties of chlorine are, therefore, due to the oxidizing powers of the liberated ozone. The sulphur and phosphorus compounds with hydrogen are decomposed by chlorine. When this gas is brought into contact with sulphureted hydrogen, chlorhydric acid is formed and sulphur is pre- cipitated. On these chemical facts rest the deodorant and disinfectant powers of chlorine. Binz has lately made an elaborate study of the effects of chlorine, and he finds that in animals it has a distinct nar- cotic effect ; that it suspends the functions of the cerebrum, but does not impair the contractility of muscle, or the irritability of nerves. Therapy. — Chlorine gas will arrest putrefactive decomposition of animal matters, and may, therefore, be employed as a preservative of anatomical preparations. As a deodorant and disinfectant it may be used to destroy foul effluvia and disease- germs. It is irrespirable in sufficient quantity to affect disease-germs in the living subject, and it destroys the colors and even texture of fabrics, so that it is rarely used for disinfection of the person or of the clothing of patients. Chlorine- water, chlorinated soda, and solutions of chlorinated lime, are employed locally in scarlet fever, diphtheria, aphthae, and gangrene of the mouth and fauces. Their chief utility consists in removing fetor, but they probably, also, exert a toxic influence on disease-germs. 3 Aquae chlori, § ss ; aquse destil., 1 iijss ; syrupi simpl., § ss. M.

Chlorine-water was formerly much employed in scarlet fever, ty- phoid, typhus, etc. Its use in these affections was predicated on its presumed power to arrest the zymosis of the morbid ferments. It need hardly be stated that such notions are no longer entertained. These chlorine preparations are unquestionably serviceable as deter- gent, deodorant, and antiseptic applications to sloughing and gangre- nous wounds. A solution of chlorinated soda is employed to prevent infection by animal poisons, the bite of serpents and insects, and the syph Hit ic v irus. Formerly chlorine-water and chlorinated soda were used in chronic hepatic affections, but there is no evidence that they are serviceable. The toxic effects of chlorine gas may be prevented by ammoniacal gas, forming ammonium chloride. Albumen is the most suitable and convenient antidote to the chlorine preparations taken into the stom- ach. It should be given freely in the form of milk, eggs, flour, etc. Bromum. — Bromine. Brome, Fr.; Brom, Ger. A dark-red liquid, having a strong, disagreeable odor. It is sparingly soluble in water, more soluble in alcohol, and still more so in ether. Physiological Actions. — The actions of bromine, considered from the chemical point of view, are similar to those of chlorine ; it decom- poses hydrogen compounds, forming bromhydric acid, and precipitating or separating the element associated with hydrogen. It is therefore a deodorant and antiseptic. The vapor of bromine is intensely irritant to the air-passages. It combines with the water and sets free ozone, which energetically attacks the mucous membrane. In sufficient quan- tity, laryngitis, bronchitis, and pneumonia will be produced by the inhalation of its vapor. Applied in the liquid form, and undiluted, bromine acts as an energetic and very painful escharotic. A brownish slough is formed, which is afterward slowly detached. Internally, by the stomach, bromine acts as a corrosive poison, producing violent gas- tritis, and the phenomena of depression and collapse, which attend the action of corrosive poisons in general. Therapy. — The vapor of bromine is an efficient remedy in acute coryza and hay-asthma: $ Bromi, 3 ss ; alcoholis, 3 iv. M. Sig.: For^ inhalation. A small quantity of this solution may be placed in a wide-mouthed vial, and vaporized by the warmth of the hand. The vapor should be snuffed into the nose. It probably acts, as already explained, by setting free ozone. The activity of the pollen of plants, the presence of which gives rise to the symptoms of hay-asthma, is 21 322 ANTISEPTICS. destroyed. The offensiveness of an ozoena may be removed by the same expedient. Chronic nasal catarrh may not unfrequently be greatly benefited by the vapor of bromine. Hammond has proposed the internal use of a solution of bromine, as a substitute for the bro- mides in the treatment of epilepsy. Besides its disagreeable qualities, and its irritant action, it has no advantages over the bromides. The most important use of bromine is as an escharotic. For the destruction of chancre, it is probably the best caustic. Hospital gan- grene, the experience of the rebellion demonstrated, was more certainly arrested by bromine than by any other escharotic. For the destruction of carcinoma uteri, this agent is preferred by some eminent gynaecologists. When used for these purposes, pure bro- mine is applied, by means of a glass rod, thoroughly, to the diseased or sloughing or gangrenous surface. The objections to the use of bromine are its fetid odor, its vola- tility (boils at 117° Fahr.), and the pain which attends its escharotic action. Acidum Carbolicum. — Carbolic acid. Phenique acide, Fr. ; Carbol- sdure, Ger. A product of the distillation of coal-tar. Is either in acicular crystals or in crystalline masses ; white or colorless when perfectly pure, but, even when slightly impure, either reddish or be- coming so on exposure ; deliquescent and readily assuming the liquid state in the presence of a little water, yet not dissolving ; of a strong odor and taste, recalling those of creosote, but distinct ; fusible at from 93° to 106°, forming an oily liquid. It is soluble in from twenty to thirty-three parts of water, the purest being most soluble. Alcohol, ether, chloroform, glycerin, and the essential oils, dissolve it freely. It combines with alkalies and other salifiable bases, but its compounds have still an alkaline reaction and are decomposed by the feeblest acids, even by carbonic acid. Dose, gr. \ — gr. j. Acidum Carbolicum Crudum. — Impure carbolic acid. Is either colorless or has a brown shade. It consists of carbolic and cresylic acids, in variable proportion, with impurities derived from coal-tar, which vary from ten to thirty per cent. Glyceritum Acidi Carbolici. — Glycerite of carbolic acid (not of- ficial), ( | ij carbolic acid ; half a pint of glycerin). Aqua Acidi Carbolici. — Carbolic-acid water (not official), (glycer- ite of carbolic acid, 3 x ; water, one pint). Dose, a teaspoonful to a half-ounce. Unguentum Acidi Carbolici. — Ointment of carbolic acid. (Car- bolic acid, 10 parts ; ointment, 90 parts.) (IT. S. P.) Creosotum. — Creosote. A product of the distillation of wood-tar. A colorless, oily, neutral liquid, having a strong, characteristic odor, CARBOLIC ACID. 323 and an acrid, burning taste. Is sparingly soluble in water, but mixes in all proportions with alcohol and ether. It is distinguished from carbolic acid, which it in some respects closely resembles, by not coagulating collodion when mixed with it, and by not imparting a blue color to a slip of pine-wood dipped first into an alkaline solution of creosote, and then, after drying, into mu- riatic acid. Aqua Creosoti. — Creosote-water (creosote, 1 part ; distilled water, 99 parts). Dose, a teaspoonful to an ounce. Carbolic acid has largely superseded creosote as a remedy. Antagonists and Incompatibles. — Combination with alkalies di- minishes, but does not entirely check, the physiological activity of carbolic acid. Saccharate of lime, or lime, is probably the most effi- cient antagonist from the chemical point of view (Th. Husemann). In cases of poisoning, this substance should be given freely. The mucous membrane should be protected as far as possible by the ad- ministration of vegetable demulcents, but not by oils and glycerin, which favor absorption. I am indebted to Dr. A. C. Post, of New York, in a verbal communication, for the important fact that atropine is a physiological antagonist to the systemic symptoms induced by carbolic acid. He was induced to administer atropine in a case of poisoning by carbolic acid, on observing the minutely contracted pu- pils and the failing circulation. The result was successful. Similar success has attended the same practice in other cases. Experiments on animals have also demonstrated the existence of this antagonism, which may now be regarded as an established fact. The rules for guidance in the administration of atropine are the same as in other cases : a sufficient quantity of the antagonist is administered to main- tain dilatation of the pupil and to overcome the depression of the cir- culation and respiration. Elimination should also be promoted by the free use of diluents. Synergists. — All of the phenols, the antiseptics, the motor depres- sants, etc., increase the effects of carbolic acid. Physiological Actions. — Applied to the integument or to the mucous membrane, carbolic acid produces a burning sensation of short duration, and there is formed a whitish, superficial eschar, which subsequently becomes brownish. The taste of carbolic acid is sweet- ish, cooling, and then pungent and hot. When swallowed by accident or design, the mucous membrane appears as if brushed over with a strong solution of nitrate of silver, and becomes hard and dry like leather. This appearance is observable about the lips, fauces, the oesophagus, the cardiac and pyloric extremities of the stomach, and the summits of the folds of the mucous membrane in the organ gen- erally. This change in the condition of the membrane is due to the power of carbolic acid to coagulate the albumen of the tissues. Vom- 324 ANTISEPTICS. iting is not constant, even when toxic doses are swallowed, and the vomited matters smell of the poison. From medicinal doses, a cooling, rather grateful sedative effect is experienced in the stomach. It dif- fuses into the blood with great facility, from the stomach, from the external integument, and from wounded surfaces. Cases of poison- ing have resulted from application to a patch of psoriasis (Toel), to scabies (Hoppe-Seyler, Machin), to the uterine cavity, after the enu- cleation of a fibroid (Rheinstadter), to abscesses (Kohler, Wallace, White), to the rectum for the relief of ascarides (Pinkham, Mi- chaelis), and to the integument and wounds, in cases of antiseptic surgery. Diffusion takes place with such rapidity, from these various sources, that formidable symptoms arise in a few minutes. The amount necessary to produce distinct effects varies ; besides the dif- ference due to age, there are variations in susceptibility. A one-per-cent solution has caused serious symptoms when injected into an abscess and into the rectum. Six drops of the pure acid have caused danger- ous symptoms, and a teaspoonful has terminated fatally, but one case is reported in which this amount was recovered from when taken by a child two and a half years old (Dessau). A tablespoonful has caused death in several instances (Cowling, Packer, and others). In Hoppe- Seyler's cases, while the two apprentices were rubbing each other's backs, both were seized suddenly with giddiness, vertigo, and tension of the head, and quickly passed into unconsciousness. These effects are also experienced when the poison is taken into the stomach. The warnings of danger, which may be expected when the remedy is brought in contact with the tissues at any point, are, besides the local irritation, sudden vertigo, contracted pupils, pallor of the face, em- barrassed respiration, and feeble circulation. When the dose is a fatal one, unconsciousness quickly supervenes, the breathing becomes ster- torous, the surface grows cold, the action of the heart gets more and more feeble, and death finally occurs from failure of respiration. Con- vulsions occur in animals, but in man this symptom is wanting, or at most fibrillary trembling, and some trismus of the jaws, are present. The changes in the blood induced by carbolic acid have been much disputed. That it enters the blood as carbolic acid seems positively established, although, having acid properties, it may become a carbolate. The acid has been discovered in the blood by Hoppe-Seyler. That it appropriates oxygen and thus undergoes some change in the blood is highly probable. Husemann maintains that the blood in carbolic-acid poisoning is very much altered in character, becoming dark in color and coagulating with difficulty, but in the reports of various post-mor- tem examinations it is remarked that the blood was coagulated in the heart and great venous trunks. Outside of the body the blood is quickly changed on the addition of carbolic acid, but these changes do not correspond to those which occur within the body. The action of CARBOLIC ACID. 325 the heart is at first slowed, but toward the end it becomes rapid. The blood-pressure falls considerably below the normal, due, Hoppe-Seyler says, to vaso -motor paresis. The first slowing of the heart is caused by stimulation of the end-organs of the vagus, and is prevented by division of the trunk of the nerve. The subsequent rapid action is due to the removal of the inhibition from paralysis of the vagus. Res- piration is at first stimulated and the respiratory acts are more frequent, but they are also more shallow. Division of the pneumogastrics does not entirely prevent this stimulation, although it lessens the effect, whence it is concluded that carbolic acid also stimulates the respiratory center in the medulla (Salkowsky). This conclusion is strengthened by the fact that, if the vagi are previously divided, the administration of carbolic acid will still increase the respiratory acts for a time, show- ing that the stimulation of respiration must be effected by an action on the end-organs of the vagi in the lungs as well (Salkowsky). Low- ering of the temperature has been constantly observed in the experi- ments on animals, and in the cases of poisoning of man. The surface of the body is cool, and more or less livid. There are several factors concerned, doubtless, in the reduction of temperature. The diminu- tion in the blood-pressure and the arrested oxidation are the chief. The power of carbolic acid to reduce the temperature of fever is also clear, but in this respect it is inferior to salicylic acid (Eisenstein). In cases of poisoning the reduction of temperature reaches several de- grees, but in the normal condition in man ordinary medicinal doses have but little effect in this direction. A more or less minutely contracted pupil is a nearly constant phe- nomenon in carbolic-acid poisoning. It can hardly be doubtful that this effect is due to paralysis of the radiating fibers, leaving the cir- cular fibers unopposed. Carbolic acid unquestionably acts on the cerebral lobes — on the centers of conscious impressions — and suspends their functions. Vertigo and singing in the ears occur, and then con- sciousness is lost, the reflexes are suspended, and complete muscular resolution ensues. In warm-blooded animals clonic convulsions are produced, succeeded by paralysis. By direct application, as Bill was the first to demonstrate, carbolic acid suspends the irritability of the sensory nerves. If a tract of the integument be painted over with pure carbolic acid, an incision may be made into the part without the least pain being experienced. The peripheral nerves, sensory and mo- tor, are not affected by the systemic action. The muscles after poison- ing respond energetically to the usual forms of stimulation. It follows, then, that the action of the poison is centric and not peripheral (Sal- kowsky, Lemaire, Rothe). The elimination of carbolic acid takes place by various channels of excretion, chiefly by the urine. It may be detected by the odor in the breath of poisoned animals (Lemaire). It has been found in the 326 ANTISEPTICS. saliva by Hoppe-Seyler, but Bill could not detect it in the perspiration or in the f aeces. Hoffmann maintains that carbolic acid undergoes oxi- dation in the blood, but, as a part of it may be separated unchanged from the urine, this statement is not wholly true. That much of the carbolic acid taken is oxidized before being excreted is proved by the character of a secondary product which appears in the urine. One of the earliest indications of the toxic action of carbolic acid, especially when applied locally, is a dark-greenish, blackish, or smoky hue of the urine. Although this appearance does not actually prove that danger to life is imminent, it is a warning to be heeded. One of the results of the oxidation of carbolic acid is the formation of oxalic acid. The same process takes place in animals, in whom carbolic acid is excreted as oxalic. Doubt has been thrown on the methods by which carbolic acid is detected in the urine of those taking it, through the experiments of Stadeler, who has discovered that carbolic acid is present in normal urine. Hoppe-Seyler, however, has proved that, by Stadeler's process* carbolic acid is made from the indican of the urine (Hermann). The elimination of carbolic acid taking place through so many channels is readily effected, and probably the whole amount is thrown out in twenty-four hours. When death occurs very quickly in fatal cases of poisoning, the tissues and organs will smell distinctly of the poison (Ogston). Death has occurred in a few minutes — in a great majority of the fatal cases within two hours (Jeffreys), and is rarely postponed to two days. The amount of carbolic acid present will therefore vary. There are no characteristic post-mortem appearances, except the changes wrought at the points of contact with the acid. The mucous membrane of the mouth, fauces, oesophagus, and stomach, where acted on, appears corrugated, tough, and discolored — whitish changing to brownish discoloration, surrounded by a zone of hyperemia, or capil- lary haemorrhages here and there sloughing off. Congestion of the viscera generally, especially of the brain and the meninges, is a con- stant phenomenon. The lungs are cedematous as well as congested. The heart may be distended with loose clots, and relaxed, or empty and contracted. By some observers changes akin to those of phos- phorus-poisoning have been uniformly discovered (Neumann), i. e., acute fatty degeneration of liver, heart, kidneys, and other organs, notably the renal epithelium. Husemann, Salkowsky, and others, deny the reality of these observations, so that further examinations are necessary to determine this point. Therapy. — Nausea and vomiting due to an irritable state of the stomach-nerves are relieved by carbolic acid. Combination with bis- muth enhances the effect. 1} Acidi carbolici, grs. iv ; bismuthi sub- nitrat., 3 ij; mucil. acacia?, § j; aquae menth. pip., 3 iij. M.

Attacks of cholera mor- bus and cholera infantum are not unfrequently very promptly arrested CARBOLIC ACID. 327 by the exhibition of carbolic acid, or the combination of carbolic acid and bismuth. Eructations of gas, due to the fermentation of foods, and the vomiting of yeast-like matters, especially when due to the presence of sarcina, are often arrested by this remedy. Good results have been obtained by the use of carbolic acid in Asiatic cholera. Combination with iodine is said to be more effective (Choleratropfen). $ Acidi carbolici, grs. iv ; tinct. iodi, gtt. xvj ; aquae menth. pip., 3 iv. M. Sig. : A tablespoonful every hour, or oftener. The same formula has been used successfully in cholera nostras and cholera in- fantum (Rothe). Based on its power to arrest toe action of ferments, carbolic acid has been used, with certainly temporary good results, in diabetes of hepatic origin (Ebstein, Habershon). Inhalations of carbolic-acid spray possess a high degree of utility in chronic nasal catarrh, hay-asthma, chronic bronchitis, and whoop- ing-cough. A solution in water, to the proportion of one per cent, is a suitable solution for this purpose. It may be combined with the tincture of iodine. The efficacy of these inhalations in hay-asthma and in whooping-cough is probably due to the fact that carbolic acid destroys the minute organisms (cacobacteria, pollen), on the presence of which the morbid action in these maladies depends (Letzerich). The vapor of carbolate of iodine may be inhaled in these diseases. The warmth of the hand suffices to vaporize a mixture of carbolic acid and tincture of iodine. In pulmonary phthisis, when there is much teasing cough, or when expectoration is profuse and foul-smelling, these inhalations are ser- viceable. In gangrene of the lung, carbolic spray and the acid inter- nally are used to destroy the fetor. A one-per-cent solution of car- bolic acid and a mixture of carbolic acid and iodine have been injected with asserted advantage into phthisical cavities through the parietes of the thorax. Internally, also, creosote and carbolic acid, especially the former, have been used with conspicuously good results in the treatment of the several forms of consumption, except phthisis florida. Probably the most useful observations to illustrate this point are those of MM. Bouchard and Gimbert. They used pure creosote from wood, and in the following formula : Pure creosote, 13*5 parts ; tincture of gentian, 30 parts ; alcohol, 250 parts, and sufficient Malaga wine to make up a thousand parts. Of this solution from two to five tablespoonfuls are taken daily. In other cases the creosote was given in cod-liver oil, which is an excellent vehicle — 2 parts of pure creosote to 150 parts of cod-liver oil. The daily quantity varied from six to nine grains, and in rare cases from twelve to fifteen grains. Of ninety-three cases of phthisis treated with this remedy, twenty-five were apparently cured, twenty-nine were improved, eighteen remained no better, and twenty- 328 ANTISEPTICS. one died. Creosote thus had a good effect in fifty-four out of ninety- three cases. The evidences of improvement consisted in the diminution of the expectoration, cough, and fever, and increase in the appetite, strength, and weight of body. The diminution of the expectoration, and consequently of the cough, was the first evidence of improvement, although at the beginning of the treatment the cough is apt to be in- creased for a short time by creosote. If the cough and expectoration are constantly increased, the medicine must be stopped. The danger of haemoptysis is rather lessened than increased by the creosote treat- ment. Schnitzler, of Vienna, has employed, recently, the subcutane- ous injection of carbolic acid in more than one hundred cases of con- sumption. He practiced the injections daily, sometimes twice a day, administering each time from one eighth to one fourth of a grain. The result was, in most cases, the fever was reduced, the pulse became slower and stronger, and the night-sweats were diminished. He con- cludes that these injections are nearly if not quite as effective in re- lieving hectic as quinine. Influenced by the germ theory of disease, carbolic acid has been much prescribed in the treatment of typhoid fever, diphtheria, scarlet fever, erysipelas, etc. Whether the theory be true or false, there can be no doubt of the good effects of creosote and of carbolic acid in these diseases. Pecholier, of Montpellier, has given creosote in sixty cases of typhoid, set apart for study of the results of the action. Good effects were obtained ; the temperature kept down ; the delir- ium and insomnia were much less ; the intestinal disturbance declined, and thus the violence of the disease was distinctly lessened. M. Cha- pelle maintains that it cuts short an attack of typhoid. In the other maladies above named, the evidence of the good effects of carbolic acid is constantly accumulating. Besides the internal administration, local application to the fauces of spray, or suitable solutions, are use- ful in diphtheria and scarlet fever to remove fetor, and to destroy the germs of contagion which may be lodged there. Recently Rothe has treated a number of cases of typhoid fever, with great success, by a mixed antiseptic and antipyretic method, in which he employs carbolic acid and iodine administered in infusion of digitalis. The author has for several years treated the cases of typhoid and typho-malarial fever so called, which have been in his hands, with a drop each of tincture of iodine and liquefied carbolic acid every two or three hours, with results which were certainly most favorable. As Rothe has observed, this antiseptic treatment lowers the heat, lessens the diarrhoea, im- proves the mental state, and, indeed, diminishes the severity of the disease remarkably. The value of carbolic acid as a remedy in mala- rial fevers seems now conclusively established. The experiences of Eisenstein in the Vienna General Hospital are especially valuable. He obtained distinct curative effects in twenty-four cases of the tertian CARBOLIC ACID. 329 and in four cases of the quotidian type of intermittents. The author has found the combination of carbolic acid and iodine of great value in chronic malarial infection, and in the more acute cases after quinine has stopped the paroxysms. As an antipyretic, Eisenstein justly re- gards carbolic acid as inferior to salicylic. It is probable that resor- cin, hydroquinone, and other phenols, will prove more useful than either. Dr. Lecaille has found carbolic acid remarkably efficacious in yelloio fever, and even after the occurrence of the ominous " coffee-grounds " vomit. He administers it both subcutaneously and by the stomach. The dose of carbolic acid for internal use ranges from half a grain to two grains, or of the liquefied acid from half a minim to two min- ims. It may be given in mint-water, which covers the odor some- what. This quantity may be repeated every hour or two, if necessary, without producing ill effects, if not too long continued. As mentioned above, the quantity given by Bouchard and Gimbert sometimes reached as high as fifteen grains a day. The mixture of bismuth, mucilage, and glycerin, is an excellent vehicle. When iodine and carbolic acid are given together, a colorless carbolate is formed when they are dropped into water. Parenchymatous Injection of Carbolic Acid. — The deep-seated injection of carbolic acid has been proposed and successfully practiced for the relief of various morbid states. For this purpose a two-per- cent solution is most suitable. A solution stronger than this may excite inflammation in the part and coagulate the blood. It is di- rected by Htiter that the needle of the hypodermatic syringe be first inserted into the inflamed part, and, if no blood flows out through the needle, it will be known that a vein has not been penetrated. From twenty to thirty minims of the solution are then injected. The in- jections are made once or twice a day in acute diseases, and on alter- nate days, or less frequently, in chronic cases. Very remarkable results have been obtained from these injections in erysipelas (Htiter, Auf- recht) and in pleuro-pneumonia (Kunze). Dr. Tessier, of the Mauritius, reports that i?itermittents are rapidly cured by the injection of three quarters of a grain of carbolic acid dis- solved in twenty minims of water. The parenchymatous injection of carbolic acid is more especially adapted to the treatment of certain surgical maladies. Htiter has employed this method successfully in lupus, chancroid, secondary syphilitic abscesses, ulcerations, synovitis (injected into the affected joint), fistulm, enlarged bursal, hydrocele, etc. Levis, of Philadelphia, cures hydrocele h j injecting liquid carbolic acid into the sac after drawing off the fluid. He first inserts the needle of the syringe so that it may be certain the point rests in the cavity. Then the fluid is drawn off, and finally the acid, a drachm or two, is injected through the needle. 330 ANTISEPTICS.

Undiluted carbolic acid is used as a mild escharotic to the so-called mucous patches, to condylomata, vegetations, etc., lupus, scirrhus, cau- liflower-growths, etc. The author has witnessed results which appear to him to justify the statement that carbolic acid, applied undiluted to the cancerous sore and injected underneath, limits the extension and retards the growth of the disease. In several cases, the disease having recurred at the site of the operation for its removal, the author has apparently arrested the morbid process by injecting beneath and into the new formation daily a syringeful of a five-per-cent solution of carbolic acid. The action in these instances seemed to be local : there were none of the evidences of systemic impression of the poison, and no diffusion of the cancer-germs took place from the point of in- fection. If further experience confirms these observations, we have in this method a most important contribution to our resources. Undiluted carbolic acid is an efficient application to xdcers of the cervix uteri, chronic endo-cervicitis, and endo-metritis. It may be ap- plied undiluted without risk to the mucous membrane of the uterine cavity, on the cotton-wrapped probe, after preliminary dilatation of the canal. There is, probably, no better means of treating uterine catarrh. Solutions of carbolic acid, of average strength, have the power to check suppuration, and to correct the fetor of sloughing and ill-condi- tioned wounds. The methods of Mr. Lister's antiseptic treatment in- clude a much more extended application of carbolic acid. Embrac- ing the fermentation theory of M. Pasteur, Mr. Lister holds to the necessity of excluding germs from contact with wounded surfaces. Operations by the method of Mr. Lister must be performed under and in a spray of carbolic acid (one part to forty). The solution may be pulverized by the ordinary hand-ball atomizer, or better by a Siegle's steam atomizer. All knives, sponges, and ligatures must be " car- bolized " before coming into contact with the wounded surface. The antiseptic dressing is thus described by Mr. Lister : " It consists of CARBOLIC ACID. 331 two pieces of folded gauze and mackintosh (fine cotton cloth with a layer of caoutchouc), an anterior and a posterior one. The wound is covered with several thicknesses of gauze dipped in a solution of car- bolic acid (one to forty), and over this is placed the folded gauze and mackintosh, of sufficient size to extend beyond the margins of the wound in all directions." The dressing is confined by turns of a " gauze bandage," and is allowed to remain undisturbed for from two days to a week, " the general rule being that the dressing should be changed on any day on which the discharge is observed to have ex- tended beyond the edge of the folded gauze." Antiseptic gauze consists of cotton cloth charged with the follow- ing : " One part of crystallized carbolic acid, five parts of common res- in, and seven parts of solid paraffin " — the paraffin and resin are first melted together, and the acid is then incorporated by stirring. A very complicated process, too elaborate for insertion here, is described by Mr. Lister, for diffusing the above-described mixture equably through the cotton cloth. For lubricating instruments, especially catheters and bougies, he advises a solution of one part of carbolic acid in twenty parts of olive-oil. Carbolized silk sutures are "prepared by immersing a reel of the silk in melted beeswax, mixed with about a tenth part of carbolic acid, and drawing the thread through a dry cloth as it leaves the liquid, to remove superfluous wax." The following is the University College formula for the prepara- tion of carbolic-acid plaster : " Shellac, 75 ; carbolic acid, 25. Melt the shellac with 8 of the acid, and then add the remaining 17, and mix thoroughly. The mixture should be spread on linen, and should be coated with a solution of gutta-percha in bisulphide of carbon." The admirable results in the treatment of wounds obtained by Lis- ter have been fully confirmed by various competent observers (Nuss- baum, Thiersch, Yolkmann, Bardeleben), and, although objectors have risen to deny the superiority of the method, it has been shown that the ill-success complained of was due to inattention to the various de- tails necessary. Toxic Symptoms induced by Carbolic Acid when used ex- ternally. — The extraordinary extent to which carbolic acid is now applied in surgical practice renders it necessary to devote some atten- tion to the symptoms indicating a dangerous degree of absorption. This form of poisoning occurs under two forms : one, sudden, the patient sinking into collapse immediately after the dressings are ap- plied ; the other, occurring insidiously, after some weeks of treatment and applications of the antiseptic dressings. Kuster, of Berlin, relates five cases of the first form, in which the patients, after the dressings were applied, sank at once into a condition of collapse like the state of shock from a most formidable surgical operation. Only one of these cases recovered. The diagnosis of this toxic state from surgical shock 332 ANTISEPTICS. will be referred to presently. In the other form of poisoning the symptoms appear gradually, and are apt to be attributed to a com- mencing septicaemia. Loss of appetite, nausea, feverishness, head- ache, vertigo, and clonic spasms, are first experienced, prostration sets in, and a more or less profoundly comatose state develops. The onset of these symptoms, or the depression which initiates the morbid phe- nomena in the first form, occurs at a time when more favorable symp- toms are properly expected. But the diagnosis is arrived at readily by an examination of the urine. The change in the color and the peculiar odor of the urine observed in carbolic-acid poisoning have been referred to, but the chemical tests are more important. Accord- ing to Baumann, we have, in Sonnenberg's test, the best means of de- termining the presence of carbolic acid. This test depends on the fact that any carbolic acid in the urine unites with the sulphates to form the sulphocarbolates, and hence it consists in determining the amount of normal sulphates present. The urine is first acidulated with strong acetic acid, and baric chloride is then added in excess. A copious precipitate, consisting, for the most part, of baric sulphate, is formed, if the urine is healthy ; but if it contain carbolic acid, scarcely any pre- cipitate will be thrown down, because of the formation of soluble sul- phocarbolates. The researches of Baumann have furnished us with an antidote of a chemical kind, which may be applied if there is time. He has shown that sodic sulphide forms in the body, with carbolic acid, the innocuous sulphocarbolate, and hence a soluble sulphate, as Glauber's salts, will be a proper antidote. As, however, the toxic ac- tion of carbolic acid is very speedy, the chemical antidote may not have time. Under these circumstances it will be found, probably, that the physiological antagonist is more speedy and effective. Atro- pine is apparently a most certain antagonist. It has succeeded in some very unpromising cases, and in my experiments on animals the results have been most favorable to the existence of the antagonism. Carbolic acid enters into the composition of Morrell's antiseptic fluid, which is used as a disinfectant for general purposes, and for the preservation of bodies. The following is the formula : " Dissolve 13"5 parts of arsenious acid and 6 '9 parts of sodic hydrate in 15 to 20 parts of water ; add enough carbolic acid until the clear fluid, after stirring, appears turbid (that is, until the liquid is fully saturated with carbolic acid), and dilute with water to make 100 parts." Sulphocakbolates. — Soclii Sulphocarbolas. Sulphocarbolate of sodium. Potassii Sulphocarbolas ; Calcii Sulphocarbolas ; Magnesii Sul- phocarbolas. Of these salts, the first-named is the most important, and is the only one official. The first step in the formation of these salts consists in the production of sulphocarbolic acid, obtained by dissolving one CARBOLIC ACID. 333 part of crystallized carbolic acid in an equal weight of strong sulphu- ric acid. The next step consists in the formation of sulphocarbolate of barium, from which the other salts are obtained by double decom- position. Sulphocarbolate of sodium occurs in transparent rhombic prisms, which are permanent in the air, dissolve in about five parts of water, and are also soluble in glycerin and alcohol. Most of the sulphocar- bolates have a faint pinkish tint, and are, like the soda-salts, soluble in water, alcohol, and glycerin. The dose for internal administration ranges from ten to thirty grains. Saturated or weaker solutions may be employed topically. These preparations, devised by Dr. Sansom, were intended to secure the antiseptic and antipyretic action of carbolic acid without any of the caustic and depressing action of the latter. In such septic diseases as diphtheria, the eruptive fevers, puerperal fever, they may be used freely. There seems little ground for the assumption that the carbolic acid is freed from its associates in passing through the organism, for -the sulphocarbolates do not have the effects of carbolic acid, and the urine does not have the greenish, blackish, or smoky hue characteristic of the latter remedy. There can be little doubt that the sulphocar- bolates are excellent topical applications to the inflamed mucous mem- brane, wherever accessible. The author has had good results from their use in acute inflammation of the fauces, in tonsillitis, in catarrh of the nares, in otorrhoea, and also in gonorrhoea. These salts are useful as deodorant and antiseptic applications to unhealthy wounds and ulcerated surfaces, to aphthae in children, etc. Although the sulphocarbolate of sodium has been added to the new pharmacopoeia list, it must be admitted that the sulphocarbolates do not maintain the position to which they were first introduced.

A neutral principle obtained from the bark of Salix helix Linne, and of other species of Salix. Colorless, white, silky, shining crystals, permanent in the air, odorless, having a very bitter taste and a neutral reaction. Soluble in 28 parts of water, and in 30 parts of alcohol at 59° Fahr. ; insoluble in ether or chloroform. (U. S. P.) Dose, 3] — 3 ij. So little soluble, it were better admin- istered in a wafer, powder, or emulsion. Actions and Uses. — Salicin promotes appetite and the digestion — properties which it possesses in common with other bitters. It is an antiferment, and has antiseptic powers similar to quinine and salicylic acid. The latter is a derivative of salicin. It is destructive to bac- teria and vibrio, and prevents the reaction of amygdalin and emulsin, and of ptyalin on starch. It does not produce very sensible effects even in large doses, and is without toxic activity. It has been used as a substitute for quinine in the cases of disease to the treatment of which the latter is applied, especially in the treatment of intermittents. It is, however, much inferior to quinine. Salicin is an excellent stomachic tonic in atonic dyspepsia, and is a serviceable remedy to prevent the fermentations which take place in the foods in cases of g astro-intestinal catarrh. In the chronic diar- rhoea of children, it has been employed successfully. The good results obtained from it in these cases are doubtless due to its antiferment properties and its lack of irritating qualities. The most important use of salicin thus far proposed, is in the treat- ment of acute rheumatism — information which we owe to Dr. Mac- lagan. He concludes, as the result of his experience, that the more acute the case the more beneficial the remedy ; that the good effects are always experienced within forty-eight hours ; that, sometimes, the disease is at once arrested ; that relief of pain and fall of temperature are the earliest effects produced. Maclagan gives from ten to thirty grains every two, three, or four hours, in powder mixed with water. " Fifteen grains every three hours is a medium dose." Much confirmatory evidence has been published ; but, on the whole, salicin is generally regarded as inferior to salicylic acid. There are conditions of the system, however, in which salicin should be pre- ferred to any of its congeners. In those cases characterized by weak heart, whether from adherent pericardium, myocarditis, fatty degen- eration, or other causes, salicylic acid may be dangerous. Again, SALICYLIC ACID. 335 when the vaso-motor system is depressed, salicin is far safer. As the curative results obtained from salicin are but little inferior to those from salicylic acid, whenever the latter is contraindicated, the former may be confidently relied on, if efficiently administered.

Acidum Salicylicum. — Salicylic acid. Acide salicylique, Fr. ; Sali- cylsdure, Ger. Properties. — Salicylic acid crystallizes in needle-shaped crystals, which are soluble in alcohol and ether, and in hot but not in cold water. It is without smell, and its taste is slight and not disagree- able. The solubility of salicylic acid in cold water is increased by the presence of neutral salts. Three parts of phosphate of sodium will render one part of the acid easily soluble in fifty parts of water. Bo- rate of sodium is still more efficient in promoting the solubility of the acid, and, as boracic acid has properties corresponding to salicylic, the borate should be preferred for this purpose. It has been shown that ten parts of salicylic acid can be dissolved in one hundred parts of water, by the addition of eight parts of borax (Bose). The borax should be first dissolved by the aid of heat, and the salicylic acid should be added gradually to the hot solution of borax. On cooling, filtration is necessary to separate a small quantity of undissolved residue. The dose of salicylic acid for internal administration ranges from ten grains to one drachm. Sodii Salicylas. — Salicylate of sodium. Dose, grs. xv — 3 j. The best mode of administration is in the form of wafer, containing five to ten grains. These may be given rapidly until the requisite quan- tity has been swallowed. Salicylate of soda may be prepared extem- poraneously by the addition of salicylic acid to a solution of bicarbonate of sodium. If the alkali is in excess, the resulting solution is brown- ish or purplish in color, and has a strong odor of wintergreen. This is not repulsive to most patients. The following is a suitable formula : ~fy Acidi salicylici, 3 ij ; sodii bicarb., 3 j ; aquae, § ij. M. Sig. : A teaspoonful every two, three, or four hours. Antagonists and Incompatibles. — The mineral acids, the me- tallic salts, and the preparations of iron in general, are chemically in- compatible. From the physiological standpoint, salicylic acid and the salicylate of soda are antagonized by the arterial and cerebral stimulants. Synergists. — The effects of salicylic acid are increased in all di- 336 ANTISEPTICS. rections by the members of the phenol group, by the arterial depres- sants, and by the anaesthetics and cerebral sedatives. Physiological Actions. — In small doses, salicylic acid may stimu- late digestion, but in considerable quantity, especially if frequently repeated, it causes uneasiness at the epigastrium, nausea, and vomit- ing. This inability of the stomach to dispose of the large doses of salicin, salicylic acid, and salicylate of soda, required in the treatment of certain diseases, is an obstacle to their use. They are diffusible and readily enter the blood. It is in a high degree probable that salicylic acid combines with an alkaline base and enters the blood as a salicyl- ate — as a salicylate of sodium, according to Salkowsky. Binz holds that the free carbonic acid present in the blood must effect the separa- tion of salicylic acid from its combinations, and hence that salicylate of soda must act as salicylic acid. It is well known, of course, that salicylate of soda does not possess the antiseptic property of salicylic acid, and, as both act similarly after their medicinal administration, it seems highly probable that the decomposition just mentioned does actually take place. An observation of Kohler seems to support the theory of Binz. Kohler found that, while ordinary blood containing salicylic acid did not yield it up to ether, the blood of asphyxia, which contains an exceptional quantity of carbonic acid, did yield up its contained salicylic acid to ether. The blood in the vessels unques- tionably contains more carbonic acid than that which has been exposed to the air. Salicin, as Senator first demonstrated, under the action of ferments, splits up into saligerine and glucose, and saligerine is readily oxidized into salicylic acid. This process is supposed to occur in the body, and hence the comparative slowness of action of salicin and similarity in its effects to salicylic acid. Spencer, examining the blood of a person taking salicin, only got evidence of the presence of the glucoside but not of the salicylic acid, and in the urine of the same subject found but a small part of the acid which ought to have ap- peared, whence he concludes that the conversion of salicin into sali- cylic and salicyluric acids, according to Senator, is but partially accom- plished in the organism. These observations adequately explain the superior activity of salicylic acid as compared with salicin. In health, ordinary doses of salicylic acid and salicylate of sodium have but little effect on the circulation. In the carefully conducted experiments of Ringer and Morshead, made on normal subjects, con- siderable doses of the acid increased the pulse-rate from ten to twenty beats, but more or less feverishness was produced by the irritant ac- tion on the gastro-intestinal mucous membrane. The manometric studies of Kohler demonstrated that this agent lowers the blood-press- ure, and this result occurred after division of the vagi, the depressors, and the spinal cord, whence it must be concluded that it accomplishes this result by a direct action on the heart and vaso-motor ganglia. SALICYLIC ACID. 337 More recent observations by Oltramare show that when salicylic acid is thrown into the veins the first effect is to increase the energy of the systolic contractions, the number of pulsations, and the blood-pressure. These effects, he finds, are due to a direct stimulation of the heart and of the motor centers. Under the influence of increasing doses, the vessels dilate, the blood-pressure falls, and finally the heart is arrested. There is, therefore, a general agreement as to the increase of the ac- tion, lowering of the blood-pressure, etc., as studied in animals, and observed on man by Ringer and Morshead. Professor See, however, fails to discover any effect by salicylic acid on the heart or blood- pressure, but, as he administered the remedy by the stomach, it is probable that he did not secure admission to the blood of a sufficient amount. The numerous observations made on the effect of salicylic acid and salicylates on the heat-function are in close accord. In health it is found that, unless toxic doses are taken, the tenrperature is but slightly or not at all affected. Riess, one of the first to make observations on this point, noted a constant reduction of the normal temperature ; but See, Ringer, Fiirbringer, and others, agree that in health this agent does not affect the temperature. Riess's conclusions were based on more than four hundred observations of the internal use of salicylic acid, and in twenty-three cases he ascertained a reduction of 1'6° Fahr., produced by five grammes (nearly eighty grains). If fever is present, whether produced artificially by the injection of septic ma- terials, or arising spontaneously, salicylic acid very uniformly effects a considerable redaction. The result, however, is not always the same. That salicylic acid has a decided antipyretic action is denied by Zim- mermann, Wolff berg, and some others ; but the weight of testimony is overwhelmingly the other way. It is certain that the degree of antipyretic effect varies in different forms of fever (Bartels, Senator, Nathan, and others), and also according to the individual susceptibility to its action. The phenomena attending the reduction of temperature are worthy of consideration. At the onset of the action, in ten to fifteen minutes after the dose is swallowed, some increase in the heart's action, a feeling of warmth through the system, and flushing of the face with suffusion of the eyes are experienced, then the perspiration begins, appearing first on the face, then on the chest, abdomen, and extremities, and presently becomes profuse. Coincidently with the sweat, the decline in temperature begins, but it continues after the sweating. There is no ratio between the amount of sweating and the reduction of fever-heat, for with much sweating there may be but slight diminution in the temperature, and with little sweating a marked decline. In febrile cases the decline of temperature varies from 1° to 6° Fahr. (Riess, Nathan, Bartels, Ewald, and others). The quantity of salicylic acid necessary to effect any considerable reduction of tem- 22 338 ANTISEPTICS. perature ranges from one to two drachms. The effect is maintained from five to twenty hours, when a repetition of the dose usually be- comes necessary. With the first effect of the agent on the heart, the pulse rises, but, as the sweating progresses, more or less slowing of the heart-beat occurs. There are differences of opinion, however, on this point. Thus, Ewald, Riess, Goltdammer, and a few others, hold that the pulse is little if at all affected ; but the usual expression is that, after a preliminary rise, there ensues with the perspiration and lower- ing of the temperature a marked decline in the pulse-rate (Buss, Star- gard, Nathan, Moeli, etc.). With the first impression of this agent on the respiratory center, the number of respirations is increased, but, with the decline of tem- perature and of the pulse, they are lessened. The excretion of car- bonic acid, Livon shows, is the greater, the larger the dose of salicylic acid, estimated during the period of increased action of the lungs. Under the influence of large doses, accumulation of the acid takes place in the cerebro-spinal fluid, causing an excitation of the roots of the pneumogastric nerve, but the excitation is succeeded by the de- pression which terminates in arrest of the respiratory function. As the effects of salicylic acid or salicylate of sodium develop, more or less headache, with a feeling of distention and frontal oppression, is experienced. Buzzing in the ears, dullness of hearing, and even deaf- ness, are usual symptoms when the doses are large. Vision is also affected, the sight becoming dim, or strabismus or ptosis occurs. In one case sudden and complete amaurosis came on (Gatti) after the ad- ministration of one hundred and twenty-five grains of salicylate of soda ; the pupils were widely dilated, the sclerotic and cornea acquired extreme sensibility, but the retina was unchanged, and the vision for- tunately was restored after ten hours without impairment. In other cases, subacute delirium, or delirium with refusal of food, and various delusions (Daly) have occurred while patients were taking consider- able doses. Ordinarily, however, the cerebral effects of salicylic acid are not unlike those of quinine. The state of the intracranial circula- tion which it induces has not been studied. According to Blanchier and Rochefontaine, salicylate of soda depresses the functions of the central nervous system, but the irritability of both sensory and motor nerves and the contractility of muscle remain unimpaired. Animals to whom salicylate of sodium is administered daily for some time, emaciate rapidly (Chirone and Petrucci). The toxic dose for the dog, ass, and horse, according to Oltramare, is one gramme per kilogramme of the body- weight. Death is due to paralysis of the heart, and not from asphyxia, as has been heretofore supposed (Oltra- mare). After death the abdominal viscera are intensely congested, unless the medulla be divided, when a marked degree of anaemia suc- ceeds to the hyperemia. It is this fact chiefly which induces Oltra- SALICYLIC ACID. 339 mare to maintain that salicylate of sodium acts on the vaso-motor center in the medulla. On man as well as on animals sometimes salicylic acid produces se- rious symptoms. The intoxication, with delirium and delusions which it causes in certain subjects, especially those suffering from acute rheu- matism, has been referred to. In drunkards it is especially apt to act unfavorably, bringing on in them violent delirium. In rare instances salicylic acid and the salicylates have induced a condition of collapse, with restlessness, delirium, great dyspnoea, feeble pulse, and involun- tary evacuations. The vaso-motor paresis, which is a result of large doses in feeble subjects, may be accompanied by great relaxation of the skin, the rapid formation of bed-sores, etc. Dr. Tuckwell, of the Radcliffe Infirmary, Oxford, gives the following symptoms as occur- ring in two cases under his observation : " Loud, deep, and sighing res- piration ; a strange restlessness, gradually increasing to delirium, and not unlike that of delirium tremens, with involuntary evacuation of urine and faeces in the worst of the two cases ; a slow and laboring pulse ; an olive-green color of the urine." No fatal case, distinctly due to these preparations, has been reported, but many have occurred in which very dangerous symptoms arose ; but, fortunately, all dis- appeared on stopping the administration of the remedy. The existence of albuminuria is an important factor in the causation of bad results (Huber). The rate of diffusion of salicylic acid has been closely studied by Blanchier and Rochefontaine, with the following results : When in- jected into the veins of a dog, salicylate of soda appeared in the saliva in four to five minutes ; in the urine, eight to ten minutes ; and in the bile and pancreatic secretion, in fifteen to twenty minutes. When taken into the stomach, it appeared in the saliva in twenty minutes, and in the urine in forty-five minutes. In man salicylic acid is ex- creted chiefly, almost wholly, by the kidneys, and appears in the urine in twenty minutes after it is taken into the stomach. It is excreted as salicyluric acid, which may be seen as a deposit at the bottom of the vessel, "of a white, feathery consistence." The urine presents a more or less deep greenish tint. The presence of the acid is readily ascertained by the solution of chloride-of-iron test. To the urine sus- pected to contain salicylic acid, add slowly, drop by drop, the chloride- of-iron solution ; phosphate of iron is first formed, which is whitish in color, but presently, if salicylic acid be present in a free state, a violet color is developed. The urine, during a course of the acid or of the salicylates, frequently contains albumen, due, doubtless, to the irrita- tion of the kidneys as elimination is going on. The facts do not yet warrant any conclusion in regard to the damage which may be perma- nently inflicted on the kidneys by the prolonged administration of this agent. The influence over the urinary excretion has been examined 340 ANTISEPTICS. by Bouchard. There is reason for believing that the urinary water is not augmented, the extractives are somewhat increased, and the phosphates and coloring-matter are unchanged. Prof. See finds that the excretion of uric acid in gouty cases is promoted. It is main- tained by others that the amount of urea present in the urine is greater than normal. Livon and J. Bernard have ascertained that salicylic acid, after being thrown into the stomach or into a vein, appears with- in an hour or two in the saliva, milk, pancreatic secretion, bile, as well as urine, and it was always found in the cerebrospinal fluid. They conclude that it acts locally at these points of contact with the struc- ture of organs. Hence, it appears highly probable that the local stimu- lation increases the product of those glands through which the acid or its salt passes, but not in the urine, if Bouchard's observations can be relied upon. Albuminuria, according to Gubler, is produced by it in some cases, and temporary impotence has been observed in others. Therapy. — The applications of salicylic acid in the treatment of disease are based on the results of the physiological examination. In the diseases of the stomach characterized by fermentative changes in the food, as in catarrh, dilatation of the organ, etc., salicylic acid is an effective remedy. The author has seen admirable results from its use in gastralgia, even when distinctly periodical. In the vomiting of a pasty, fermenting mass of ingesta, whether or not accompanied by the organism, sarcina, or other germs of fermentation, good results are derived from this remedy. In these stomachal disorders, the best effects are had from ordinary doses (five to ten grains), given in a wafer, either in anticipation of the attack — as of gastralgia appearing at a fixed hour — or during the process of fermentation in the stomach contents. As a portion of the remedy taken passes into the faeces, it is probable that salicylic acid is just as effective in the corresponding troubles in the intestines. Ilgin reports the removal of tmnia solium in six cases by the administration of salicylic acid, in eight-grain doses every hour until five doses were taken — preceding and following the acid with a dose of castor-oil. It has been employed successfully in the removal of ascarides, by local application and by internal adminis- tration. An enema of water should precede the salicylic-acid solution, which may be composed of borax and salicylic acid with some gly- cerin. I> Acid, salicylic, 3 ss ; sodii biborat., 3 ss ; aquse, Oj. M. Sig. : Warm, and administer the whole amount at one time. For a young child, this quantity should be reduced one half, or more. When the heart is weakened from any cause, salicylic acid and salicylate of soda must be exhibited with caution. The experience thus far accumulated warrants the assertion that the dose of fifteen grains of the former and twenty of the latter should rarely be ex- ceeded, if frequent repetition of the dose is practiced. From Riess, who regards salicylate of soda as a specific in typhoid fever, to Filatow, SALICYLIC ACID. 341 who holds that it is worse than useless, there are various shades of opinion, with the weight of authority decidedly in favor of the view that it is a remedy of real value. Since Riess, no one has claimed in this remedy a specific for typhoid, but it is generally admitted that it renders the course of the disease milder by keeping the temperature within safe limits (Tomkins, Hallopeau, Butt, Immermann, Senator, etc.). Weiss concludes, after an experience of ninety-six cases of ty- phoid in children, treated with salicylate of soda, that it is a powerful antipyretic in the typhoid of children, and that, while it does not shorten the course of the disease, it renders it much milder. He finds that the results are better, when the typhoid of children is treated by salicylate of soda, than have hitherto been obtained from quinine and cold baths. A still more recent English experience is to the same pur- port as the German. Dr. Tomkins finds that in the salicylates we have the means of reducing fever-heat, more certain and more agree- able than by the cold bath. In the eruptive fevers, the same prin- ciples obtain as in typhoid. Salicylate of soda is preferable to sali- cylic acid, because it is less irritating, safer, and equally effective as an antipyretic. The object of its administration is to reduce the heat, which is the most important source of danger. The amount required to accomplish this object is now definitely known. Twenty grains of the soda salt may be given every two hours, until the temperature is reduced to the proper point, at which it may be held by ten-grain doses at the same interval, unless the occurrence of an exacerbation requires the exhibition of a larger quantity. In the case of children, the daily quantity ranges from half a drachm to a drachm. Probably the best mode of administering the salt is in the form of wafer, but when these can not be obtained, a solution may be readily prepared, or the salt may be constructed extemporaneously by adding the acid to a solution of sodic carbonate as follows : Ijt Acid, salicylic, 3iv ; sodii bicarbonat., 3 j ; aquae, 1 jss ; syrup, simpl., 1 ss. M. A table- spoonful contains about twenty grains salicylate of soda. It should be borne in mind that this remedy is not safe if the heart is very weak, or if albuminuria is present. In relapsing fever, according to Riess, salicylic acid accomplishes something more than the mere reduction of temperature. Although it does not prevent the usual relapse, even when administered in large doses during the interval, it lessens the severity and duration of the relapse. It does not destroy the spirilla in the blood, nor indeed lessen their activity (Riess), and hence can not be a curative agent in this disease. In pyemia, septicemia, puerperal fever, diphtheria, etc., salicylate of sodium is used under the same rules as in typhoid. The indication for its use is high fever, and the good accomplished by it is determined by the degree in which the temperature is reduced. The antiseptic action is quite secondary to the antipyretic. In mala- 342 ANTISEPTICS. rial fevers it was supposed by Senator and others, in the enthusiasm attending the introduction of the remedy, that salicylic acid would prove equal to quinine. If administered in a full dose just before the advent of a paroxysm, it will prevent it, but it does not possess the curative powers of quinine over the effects of the malarial poison, and hence will not prevent relapses. By using salicylate of sodium to abort an impending paroxysm, and quinine to prevent relapses, the curative result will be attained with the least pecuniary expenditure. In the mildest cases of intermittents, salicylate of sodium may be de- pended on alone, but, to succeed, it must be administered before the expected paroxysm. Out of the enormous mass of published experience in regard to the value of salicylic acid in acute rheumatism, it is difficult to select. From the first trials of Buss, followed by Strieker and Traube, there has been an almost unanimous expression of opinion by the German physicians in regard to the value of this agent in rheumatism. At first it was supposed that the disease could be invariably cut short in forty-eight hours to three days, but larger observation has qualified these opinions. By way of illustration of the measure of success now attained in Germany with salicylic acid in rheumatism, we may take the recently published statistics of Diesterweg. Of oue hundred cases treated with this remedy, the disease was cut short in thirty-six or twenty-four hours ; in eighty-five, within the period of forty-eight hours ; in ninety-eight, within seventy-two hours ; in one the disease was prolonged to eighty -four hours ; and in one the remedy had no effect on the disease. It is not intended to convey the impression that the cases got well in so short a time, only that the fever and joint- swelling and pain subsided, and convalescence was established. Re- lapses occurred in eleven cases, and cardiac complications in five. In France the treatment of acute rheumatism by salicylic acid was taken up by Jaccoud, Lepine, Gueneau de Mussy, and others, but es- pecially by Prof. See, who has devoted to it several important lectures. As a result of See's observation, he concludes that salicylic acid has a marked and peculiar benefit in acute rheumatism ; that the pains in- variably cease in from twelve to eighteen hours ; that the articular swelling disappears at the end of three days, and that the fever sub- sides with the pains. If the fever persists, other joints will become affected. Out of fifty-two cases treated by Prof. See, fifty-one recov- ered in from two to three days. These results are quite equal to the German. See makes an important observation in regard to the ra- pidity with which salicylic acid and salicylate of sodium are eliminated, and the necessity, therefore, of continuing the remedy for some time after all the joint- troubles have ceased, to prevent relapses. Prof. Gubler does not share the general enthusiasm as to the value of this agent in rheumatism. He emphasizes the uncertainty and the SALICYLIC ACID. 343 dangers attending its use, and maintains that it has no antipyretic effects. In England salicylic acid and salicylate of sodium have been used with a large measure of success, but the rheumatism of England, as of this country, does not yield with the promptness characteristic of the Continental disease. The general results of the treatment, as con- ducted in England by Broadbent, Carafy, Spencer, Boggs, Greenhow, and many others, is very much as expressed by the last-named in his important communication to the Clinical Society. The temperature speedily falls, sometimes within a few hours and almost always in two or three days, the pulse declines at the same time, the pains subside correspondingly, and the joint-swelling diminishes and disappears within thre? or four days. Greenhow points out that such a result is not a cure even in the most favorable cases ; that the remedy acts very injuriously on the heart and causes a deep anaemia, and that, therefore, the duration of the disease, from beginning to the termina- tion, is not actually shortened. Dr. Maclagan (also Charteris) strongly urges the substitution of salicin, on the ground that it is equally effec- tive with salicylic acid and much less dangerous ; but it is difficult to appreciate this argument, since salicin is converted into salicylic acid in its passage through the system. In this country, the experience of the Maine physicians, and of the medical staff of the Massachusetts General Hospital, has been pub- lished. It is conceded that it has good effects. As regards the ex- perience at the Massachusetts General Hospital, the facts are as follows : In eight cases out of seventeen treated with salicylic acid, the duration of the longest case was twenty-six days, and the shortest five days, the improvement being very marked from the beginning of treatment. Of three patients who took salicylate of soda only, the duration of the disease was less than twelve days in each case, the shortest being two days. In the remaining nine cases the duration was six weeks or more. In summing up the testimony, it is clear that salicylate of soda is a most valuable remedy in acute rheumatism, but various unpleasant, even dangerous symptoms arise in some cases. Violent headache, ver- tigo, and tinnitus aurium, are common ; wild delirium is an occasional symptom ; weakness of the heart, obscuration of the first sound, and profound anaemia, are especially noted by Greenhow ; very great gas- trointestinal disturbance is now and then produced. Empis narrates a fatal case of acute rheumatism which was treated by salicylic acid. Great depression of the powers of life, in rare instances approaching collapse, has been observed. Sufficient is now known of the danger attending the salicylic medication of acute rheumatism, to justify the author in urging circumspection on the attention of his readers. The robust and vigorous rheumatics are proper subjects for this treatment, whereas, in the pale, feeble, and cachectic, especially those with weak 344 EXCITO-MOTORS. hearts, this treatment must be pursued cautiously, or not undertaken at all. Relapses are frequent, probably because of the very rapid elimination of the remedy, as suggested by Prof. See, and hence its administration must be continued for some time after all of the local and systemic symptoms have subsided. In gout, chronic rheumatism, myalgia, and lumbago, salicylate of sodium often acts most serviceably. It is more effective the more acute the malady, as a rule, but it sometimes does great good in the most chronic cases. Abbott reports the cure of sciatica, and Brun of rheumatismal irido-choroiditis, by its use. The author has succeeded in some instances very promptly in the cure of sciatica by the salicy- late of soda — the formula used being that for the extemporaneous so- lution. The cases in which this remedy has proved most efficacious, were those of functional disturbance in the nerve, the muscles being in their normal condition, and the pain having nocturnal exacerbations. It is a very interesting fact, first distinctly stated by Dr. Pye Smith, of Guy's Hospital, London, that, during the administration of salicylic acid and the salicylates, the urine exhibits the reaction for sugar on the application of Trommer's test. This has been observed in rheumatism and in other diseases treated with this agent. The urine is a little increased in amount, but its specific gravity is not changed. The reduction of the copper is effected by the acid or by the glycogen, which is one of the products of the decomposition of salicylic acid. Mtiller, the assistant of Eckstein in the clinic at Kiel, has published some important observations on the use of salicylate of soda in the treatment of diabetes. It appears that full doses of the salt cause the sugar to disappear entirely, but this is not a permanent result, for, after a time, the sugar returns. A very great tolerance to the remedy exists in this disease, and large doses may be taken with impunity. Bouchardat, in commenting on these observations, states that he has not had good results from this treatment. Since, however, the remedy is well tolerated, and during its exhibition in considerable doses the sugar disappears, it may be used with advantage at critical times to stop the waste. Salicylate of sodium has feeble antiseptic properties, and hence salicylic acid, which is even superior to carbolic acid in its power to destroy minute organisms and to prevent change in putrescible mate- rials, should be preferred for all topical applications. Being free from odor, and more active than carbolic acid, it should be used instead of carbolic acid for most purposes. For all toilet purposes, it is decid- edly preferable. It is an excellent addition to the ordinary powder dentifrices, and its solution with borax is an efficient deodorant in fetid perspiration. This disagreeable affection, as it attacks the feet, may be relieved by dusting the feet thoroughly with powdered salicylic acid before putting on the stockings. It is useful, also, to fill the in- SALICYLIC ACID. 345 terstices of the stockings with the powder. Extraordinary success has been achieved by the local apjolication of this remedy in eczema of the head and face. Those cases characterized by much weeping seem to be best adapted to the cure by salicylic acid, but eczema rubrum and eczema impetiginodes, that resisted other approved means, have yield- ed to the application of this agent (Wagner, Will). It is generally conceded that, as a local application to syphilitic idcers, salicylic acid is inferior to carbolic acid. The most important therapeutical uses of salicylic acid are in the antiseptic treatment of wounds and injuries. When it was shown that this agent had a power to destroy the activity of ferment and dis- ease-germs equal to that of carbolic acid, while it is free from the irri- tating quality and disagreeable odor of the latter, Thiersch, who is a strong advocate for Lister's antiseptic method, resorted to the use of salicylic-acid solutions. Further experience has, however, rather proved the superiority of carbolic acid in respect to the germicide and antiseptic properties for which these remedies are now so largely em- ployed. To cancer, gangrenous and sloughing wounds, pure salicylic acid may be applied in powder. To prevent the contact and multiplication of atmospheric germs, operative procedures may be conducted in sali- cylic spray, the sponges and dressings may be saturated with salicylic solutions, and the wound may be irrigated by the same. In order to carry out all the details of the antiseptic method, salicylic acid is sub- stituted for carbolic in the forms and combinations of dressings em- ployed by Lister. Wounds are covered with cotton-wool, impregnated with an alcoholic solution of the acid, in the proportion of three and ten per cent. As cold water takes up only one part to three hundred, which, however, is strong enough to destroy bacteria, etc., the addition of borax is generally, necessary to obtain a solution of sufficient strength for the antiseptic applications. A salicylic-acid plaster may be prepared as follows : Salicylic acid, 3 ss — 3 j ; white wax, 3 j ; paraffin, 3 ij ; almond-oil, 3 ij. The ingredients are melted, and rubbed up together in a heated mortar (Will), and spread on muslin. An ointment more readily melted by the heat of the body is the following : Sperm-oil, 3 jss ; cacao-butter, 3 vss ; salicylic acid, 3 ss — 3 j. This should be melted together, thoroughly incorporated, and spread on lint (Will). An ointment for the same purposes may be prepared in a simpler way by the addition of salicylic acid to simple cerate. A solution of sali- cylic acid in olive-oil, in the proportion of one drachm to eight ounces, is an efficient local application for burns. Authorities referred to : Bose, Dr. H.

History. — Resorcin is a chemical compound, discovered by Hlasi- wetz and Barth, and was obtained from certain resins by the action of fusing alkalies. They assigned to the new compound the name resorcin, partly because it is derived from a resin, and partly because it has some similarity to orcin, a peculiar substance obtained from archil. Subsequently resorcin was constructed synthetically by Korner, and at the present time it is obtained in various ways, the product being both pure and cheap (An deer). Properties. — Resorcin is a member of the phenol group. It oc- curs in tabular prismatic crystals, rather shining and lustrous, some- what sweetish to the taste, with a little after-pungency. When struck or rubbed in the dark, it appears phosphorescent. In odor it is some- what like phenol, but not nearly so pronounced. It is freely soluble in water, in the proportion of 86'4 parts of resorcin to 100 parts of water at 0° C. It is dissolved by all liquids except chloroform and carbon sulphide. Aqueous solutions exposed to the air and light, as- sume a more or less brownish tint, but without any apparent change in quality. Albuminous liquids treated with a concentrated solution of resorcin, become turbid by the formation of an albuminate of resor- cin. Various secondary products are obtained from it by the action of chlorine, iodine, bromine, nitric and nitrous acids, etc. In the pro- cess by which resorcin is produced, are also hydroqainone and pyrocate- chin. The best vehicles, according to Andeer, are alcohol, glycerin, and sirup of orange. The dose for usual purposes ranges from five to fifteen grains. For a decided antipyretic effect a drachm may be given, but this amount could not be frequently repeated. Five grains may be given every two hours, in an ordinary case. Antagonists. — From the physiological standpoint, resorcin is an- tagonized by the cerebral excitants, by the agents which raise the arterial tension, and by the cardiac and respiratory stimulants — by atropine especially. RESORCIN. 347 Synergists. — Its effects are promoted by quinine, salicylic acid, carbolic acid, etc. Physiological Actions. — Resorcin does not irritate, nor is it ab- sorbed by the unbroken integument. The solution injected into the subcutaneous tissues produces but little irritation, and never inflam- mation and abscess. Applied to the moistened mucous membrane, it causes vesication, and a white blister forms, like that from carbolic acid. It has decided anti-ferment properties, arrests decomposition in animal tissues, deodorizes, and is destructive of the minute organisms on the presence of which putrefactive decomposition is dependent. A one-per-cent solution will prevent the decomposition of urine when exposed to the air for months ( Andeer). Applied to unhealthy wounds, it arrests the decomposition, destroys the fetor, and promotes healthy cicatrization (Dujardin-Beaumetz). The action of lethal doses is necessarily to be studied on animals. Murrell has, it is true, given a good account of the symptoms produced by an overdose, but the details can be obtained only by experiments on animals. Soon after the administration of a full dose — thirty cen- tigrammes (about five grains) of resorcin per kilogramme (about thirty- five ounces) weight of the animal experimented on — trembling begins, due to fibrillary contractions of the muscles, and this passes into gen- eral clonic convulsions of an epileptiform type. These convulsions regularly increase in severity, and, reaching their maximum in a few minutes, as regularly decline, the whole duration of this phase of the action being about two hours, sometimes longer. The spinal cord is doubtless the seat of the action, since the irritability of the peripheral nerves and muscles is diminished only, and not entirely destroyed. The general sensibility is preserved, whence it must be concluded that the action of resorcin is on the motor elements (Callias). The blood seems not to be altered in respect to its composition or properties ; it presents a normal appearance, coagulates in the usual manner, and the venous blood, exposed to the air, assumes the proper red hue. The lethal dose, according to weight, is ninety centigrammes per one kilogramme. The phenomena observed when such a dose is ad- ministered are the same as those above sketched, except that sensibility is impaired as well as motility. Resorcin, through the action on the nervous system, affects the respiration and circulation when the dose is large. At first the respi- ration is greatly increased in frequency, becomes convulsive and jerk- ing, and afterward shallow and weak but rapid. The action of the heart also becomes rapid, the pulse weak and somewhat irregular, but the respiration ceases before the action of the heart. The temperature rises, and just before death attains to 103° to 105° Fahr. This increase of the body-heat is doubtless correctly attributed to the extreme mus- cular action (Dujardin-Beaumetz), and not to irritation of a hypo- 348 ANTISEPTICS. thetical heat-center. Resorcin, which acts in many respects so like quinine, however, differs from this agent remarkably in respect to the lethal effects. When a considerable dose of resorcin (thirty to sixty grains) is administered to a person in a fever, in a few minutes a sense of heat is felt about the epigastrium, and spreads thence over the system ; the face flushes and grows hot, the eyes glisten, the breathing and pulse are accelerated, and dizziness, with ringing in the ears, and frontal headache, are experienced. A good deal of discomfort, oppression of the chest, and a sense of distention of the head, are usually produced, but these sensations subside in from ten to fifteen minutes, the skin then grows moist, and in a few minutes more a profuse perspiration is pouring out on the surface of the body. The pulse then falls, cool- ness succeeds to heat, languor to tension, and the temperature of the body declines several degrees. If the feverish state has no special features, the lessening of the pulse and reduction of temperature to the normal occurs in about an hour. The pulse may be slowed one third, and the reduction of temperature be as much as three or more degrees of Centigrade or five degrees Fahr. (Lichtheim). The reduc- tion of temperature in fever is of comparatively brief duration, lasting from two to four hours. When the rise of temperature begins again, a sense of chilliness is experienced, which may even take the form of a distinct rigor. Lichtheim observed great differences in the power of resorcin in different fevers. The less the tendency to spontaneous remissions, the less the antipyretic effect. The fever accompanying pneumonia and erysipelas was less amenable to the action of resorcin than was typhoid fever, but no form of fever entirely resists its action. In the normal, the action on animals and on man corresponds closely. The correspondence also exists in respect to the action in pathological states, as above stated. To the information thus obtained may be added the experiences on healthy men, as furnished us by Andeer, by Baumann and Preusse, Fauber, and others. In small doses, the circu- lation, respiration, and temperature are but little affected. Andeer, from a dose of ten grammes (one hundred and fifty-five grains), suf- fered from dizziness, confused vision, deafness, considerable salivation ; presently extreme vertigo and loss of consciousness occurred, and then general clonic convulsions and tetanic rigidity of the muscles of the neck came on. There was no decline of temperature. All of the effects subsided in five hours. The preliminary stage of excitement produced by resorcin is often accompanied with excitement and de- lirium. In one case a deep stupor ; in others, muscular trembling and incoherence of speech were observed. The elimination of resorcin takes place almost entirely by the urine, and it is effected quite rapidly, for the greater part absorbed is excreted in an hour. The state of the kidneys, therefore, must influ- RESORCIN. 349 ence the rate of elimination, and correspondingly the duration of the physiological or therapeutical actions. The tests for ascertaining the presence of resorcin are not sensitive for small quantities. The most easily applied is the solution of perchloride of iron, which causes, when resorcin is present, a deep violet, almost black, color. Therapy. — A close correspondence exists in the therapeutical ap- plications of the members of the phenol group, and Lichtheim traces a distinct parallelism between their anti-fermentative and antipyretic action. Resorcin, having much less irritating property, is generally preferable to carbolic acid for internal and for subcutaneous use. In catarrh of the stomach, gastralgia, ulceration, and fermentative indi- gestion, Andeer reports on a series of three hundred cases in which it acted most favorably. He prescribed chiefly a three-per-cent solution. In fevers it has been given with a view both to its antiseptic and anti- pyretic actions. It is not a specific, and is only serviceable in the ratio in which it reduces heat. In erysipelas, puerperal fever, septicemia, and diphtheria, resorcin may exert an antiseptic effect. For the same reason it may be applied to the treatment of ulcerative endocarditis. In intermittent fever remarkable results have been lately obtained, which, if confirmed, will put resorcin in the front rank of remedies for malarial diseases. Indeed, it is highly probable that in one of the members of this group we will presently have a real rival and an equal to quinine. Resorcin has been used by Dujardin-Beaumetz, Andeer, and others, with great success locally in syphilitic and other sores of an unhealthy or sloughing character. Its solution may be applied as spray in affec- tions of the nose and throat, catarrhal, ulcerating, or specific. Andeer affirms that, applied in crystals or in powder, it is the most efficient remedy in diphtheritic affections, and he has employed it with equal success in anthrax. Phenoresorcill. — By the term phenoresorcin is meant, by River- din, a mixture of carbolic acid and resorcin : sixty-seven parts of the former and thirty-three parts of the latter. This mixture crystallizes by cooling, and on the addition of ten per cent of water becomes a liquid which mixes with water in all proportions. Combining thus the virtues of both remedies, phenoresorcin offers many advantages, and may well repay more elaborate investigations. Hydro quinone and Pyrocatechin ; Kairine and Kairoline ; Chino- line. — In the search for an artificial quinine, produced by a syntheti- cal process, various substances, more or less closely related, have been formed. Of these, hydroquinone and pyrocatechine are very similar in all respects to resorcin. They correspond in physiological actions, and have the same power to depress febrile temperature. They are also closely allied to quinine chemically, and possess distinct antiperi- odic power. When first produced, they were proposed as substitutes 350 ANTISEPTICS. for quinine ; the close chemical relationship was supposed to imply an equally close physiological affinity. Further studies have shown that while these agents are very useful, they are inferior in all respects to quinine. Hydroquinone and pyrocatechine are very closely allied to resorcin ; they may be substituted for this agent in corresponding doses, and they have the same range of applications. Katrine and Jcairoline are new contributions to the phenol group. Kairine is a powder having a pale buff color, is slightly soluble in water, and has a bitter, somewhat aromatic, and, to most persons, a very disagreeable taste. If inclosed in a wafer, which is the most agreeable mode of administering it, a quantity of water should be taken after it, to prevent the caustic action on the mucous membrane. Kairoline is, chemically, methyl-hydride of chinoline. It is very much less active than kairine, but the effects when produced are more lasting. The dose of kairine, as an antipyretic, is from fifteen to thirty grains, given in anticipation of the febrile rise, or it may be admin- istered in smaller doses at intervals — for example, five grains every hour, until the desired impression is effected. Kairoline, being less active by half, must be given in corresponding quantity. Chinoline. — So long ago as 1834 this substance was separated from coal-tar by Runge, and given the name Leukoline. Subsequently it was obtained by Gerhardt from the cinchona alkaloids, and by him the name chinoline or quinoline was assigned to it. Lately, chinoline has been produced synthetically by Skraup, by acting on aniline or nitro- benzol with glycerin in the presence of some dehydrating agent. Thus prepared, chinoline is an oily, highly refracting liquid and basic substance, which combines with acids to form salts. All of the salts, except the tartrate, are very deliquescent, crystallizing with difficulty, and soon losing their form ; but the tartrate is in lustrous crystals, stable even in a damp atmosphere, and yet sufficiently soluble in water. According to Donath, chinoline is not more closely allied to quinine in physiological and therapeutical actions than it is chemically. Al- though "these confident expectations, that in chinoline we have an adequate substitute for quinine, have not been realized, this remedy is still entitled to be regarded as a valuable antiseptic and antipyretic. Donath has shown that a two-per-cent solution will prevent the de- velopment of bacteria in decomposing solutions. Its power to reduce febrile heat is the same as that of the other agents of the group, except that it is greater. Indeed, chinoline is supposed to be nearly as active as quinine as an antipyretic. All of these phenol derivatives and con- geners — resorcin, hydroquinone, pyrocatechin, chinoline, etc. — possess the power to reduce fever-heat, while they are powerless to affect the normal temperature. The fall of temperature is preceded by a short period of excitement — of increased rate of cardiac movement, warmth of the surface, flushing of the face, etc. ; then perspiration begins, the BORACIC ACID. 351 temperature declines, the pulse slows and becomes weaker, and the respirations lessen in number. The degree of antipyretic effect, and its duration, vary with the different members of the group. The be- havior of the several agents is set forth with sufficient particularity above. Therapy. — These antiseptic and antipyretic remedies have been employed with considerable success in fevers, in malarial and septic disorders. Topically, they are used to arrest the multiplication of minute organisms, and to prevent the septic decompositions dependent thereon. Thus, chinoline has been applied locally in diphtheria by Seiffert with great advantage. He used a five-per-cent solution of the tartrate, which was freely painted over the affected surface ; but, subsequently, he resorted to a five-per-cent solution of pure chinoline in equal parts of alcohol and water, as more effective and less disa- greeable. In intermittent and remittent malarial fevers, resorcin, but espe- cially hydroquinone, kairine, and chinoline, have been used with marked success. A true substitute for quinine has not yet been produced, but these remedies, especially the last mentioned, have approximated closely. Further exact observations are necessary to fix the true po- sition of these antipyretics and antiseptics. Authorities referred to : Andeer, Dr. Julius. Pamphlet, Ueber Resorcin.

ANTISEPTIC OILS. 357 Composition. — The most important constituent of the oil of caje- put is cajuputol, or the bihydrate of cajuputene. To this list might be added eucalyptol, the camphor obtained from Eucalyptus globulus, and the various balsams, and cymene and terpene volatile oils ; but these remedies have already been considered else- where, so far as they possess any practical importance. Physiological Actions. — The composition of this group of oils indicates the close correspondence between them and carbolic, salicylic, and benzoic acids. So intimate are the chemical relations of salicylic acid, benzoic and cinnamic acids, that the balsams might with pro- priety be grouped with the antiseptics, for in their physiological ac- tions and therapeutical applications they are equally as closely related as in their elementary composition. Of the members of this group, thymol or thymic acid has been most elaborately studied. Lewin has shown that thymol, as respects its influence on fermentation and putrefaction, has a positive antiseptic property. Its actions are similar to those acids of the same class to which it is so closely allied chemically, viz., carbolic, salicylic, and benzoic. Locally applied, thymol, just as carbolic acid, produces pa- ralysis of the end-organs of the sensory nerves (Lewin). The effects of thymol have also been studied by Baltz. He has ascertained that from twenty to thirty grains a day are necessary to produce distinct effects. Placed in contact with the fauces, it causes an acrid sensation, which persists. It rarely excites vomiting, but a large dose induces a sensation of heat about the epigastrium, and sometimes diarrhoea. In the majority of cases thymol causes, in about half an hour to an hour, sweating more or less profuse, but distinctly less than that produced by salicylic acid and jaborandi. The urinary secretion is sometimes increased. The urine presents a dark, greenish hue, as if it contained blood. Singing in the ears, deafness, and a sen- sation of constriction of the forehead, are among the nervous phe- nomena. The researches of Lewin and Baltz place thymol in the same category with eucalyptol, salicin, salicylic acid, resorcin, and carbolic acid. Myrtol. — This new antiseptic has the same relative origin as thy- mol ; it is derived from the myrtle and is an oil, isomeric with the oil of turpentine (?). It is a very active antiseptic (Gubler). It prevents the decomposition of urine and other putrescible animal substances, and has been used to destroy the fetor of decomposing pus. As an active parasiticide it has been used successfully against the round worm, and the ascarides infesting the rectum. By Laboulbene it has been prescribed for the expulsion of taenia, with only partial success. The parasitic affections of the skin, favus, herpes, and pityriasis, are cured by myrtol. In moderate doses this agent is rather grateful to the stomach, and 358 AGENTS ACTING ON THE NERVOUS SYSTEM. is a stomachic tonic or stimulant. The most important application made of it is in the treatment of bronchorrhoea, fetid bronchitis, gan- grene of the lung, etc. Eliminated by the lungs largely, it stimulates the tissues through which it passes, and thus a local action is added to the systemic effect. Chronic bronchitis, capillary bronchitis, whoop- ing-cough, humid asthma, etc., are maladies in which it may be ex- pected to afford a large measure of relief. In hematuria not due to acute congestion, and in passive hemorrhages in general, it has been used with success. It has long been known that oil of cloves, and indeed the essential oils generally, have the power to relieve a painful state of a sensory nerve. Inserted into the cavity of an aching tooth, they suspend the pain. A solution of oil of cloves in rhigolene is a nostrum for the cure of superficial neuralgim. 3 01. caryophylli, ol. gaultherise, ol. thymii, aa 3 j ; tinct. benzoini, tinct. cinnamomi, aa f iv. M.

AGENTS USED TO MODIFY THE FUNCTIONS OF THE NERVOUS SYSTEM. In this division, remedies are employed with a view to their influ- ence over the functions of the nervous system. They do not, immedi- ately or necessarily, affect the function of nutrition; they do not enter into the formation of tissues ; and, having modified the functions of the nervous system, they are excreted from the organism in the form in which they entered it. It is probable that the selective action on this system is due to the fact that the nervous tissue is the most highly specialized in function, and therefore most susceptible to such impressions. The different parts of the nervous system are so closely united in function that a disturbance at any point is differentiated to other and often widely-separated points, and the complexus of effects is made up of many minor disturbances. For this reason it is quite impos- ELECTRICITY. 359 sible, in the present state of our knowledge, to make a classification which will sharply define the limits of activity of any particular rem- edy. Nevertheless, physiological experiment and clinical experience have furnished us sufficiently accurate information with regard to the most important actions of the remedies of this division, to justify an arrangement based on their most conspicuous qualities. AGENTS WHOSE MOST IMPORTANT QUALITY CONSISTS IN EXCITING FUNCTIONAL ACTIVITY. A.— OF THE SPINAL CORD AND SYMPATHETIC. Electricity. — Electricity Fr. ; Electricitat, Ger. Forms of Electrical Force employed in Medical Practice. — Mag- netism, static or frictional electricity (franklinism), galvanism, fara- dism (electro-magnetic, magneto-electric). Static or Frictional Electricity. This is obtained by friction from glass, as in the cylinder or plate, and by induction from the Holtz electrical machine. The last-named instrument is best adapted for medical use. The prime conductor of the electrical machine furnishes positive or vitreous electricity, and the rubber, negative or resinous. Various modes of electrization by static electricity are resorted to : 1. By sparks. In this mode the part to be acted on is made to re- ceive sparks from the machine in action. 2. The electric bath. The patient is placed on an insulated stool, and is charged with positive or negative electricity from the prime conductor, or rubber, according as he is in connection with either. Sparks maybe drawn from the affected part by presenting the knuckles or a metallic conductor. A sharp, tingling sensation, followed by red- ness and wheals, is produced by sparks, whether received from the machine or drawn from the body. 3. By the Leyden-jar. In this method, the electricity is condensed in the Leyden-jar, and the charge is transmitted through the part to be acted on. Owing chiefly to the physicians of Guy's Hospital, London, and Dr. Charcot and his pupils, Dr. Arthius and Dr. Vigouroux, of Paris, the use of static electricity as a therapeutical agent has been revived and rendered entirely practicable. Dr. Morton, of New York, and the author, simultaneously arrived at a method of using the Holtz electri- cal machine as a means of stimulating muscular contractions, and as a substitute for the faradic current in cases requiring such treatment. Before describing these manipulations it is necessary to say something regarding the structure of the Holtz machine. Various modifications of the original pattern have been introduced ; but the most successful is 360 EXCITO-MOTORS. that of Toepler. There are, however, several excellent machines adapted from the Holtz model to suit the views of mechanical theo- rists or practical electricians, which may be employed with entire confi- dence. The author has used with satisfaction a machine the revolv- ing plate of which has a diameter of fourteen inches and the fixed plate of sixteen inches. The power may be furnished by an electric motor, by a water motor or more conveniently by an assistant. In the an- nexed figure, the arrangement of the Toepler-Holtz is shown. This is Fig. 1.— The Toepler-Holtz Electrical Machine. the model which the author uses, and is found to be sufficiently powerful for medical purposes. During the winter, when the consultation-room is kept at or about 70° Fahr. by artificial heat, this instrument works with entire satisfaction. In the late spring and summer, for the most part, the atmospherical conditions are such that some means are neces- sary to preserve the instrument from moisture. This is accomplished by inclosing the machine in a suitable glass case and keeping within it some chloride of calcium to absorb the moisture. An arrangement of this kind is preferred by Dr. Morton, of New York, who uses the origi- nal Holtz machine. The Holtz machine may also be employed to procure the muscular effects, hitherto obtained only from faradic appliances. The current passing between the discharging-rods can be tapped by means of a flex- ible wire attached to the outer coating of one condenser, and another flexible wire connected with the brass knob or bar which is in communi- cation with the interior of the other condenser. The strength of the current and the rapidity of the interruptions are regulated by the dis- tance between the knobs of the discharging-rods. At every passage of ELECTRICITY. 361 a spark a muscular action takes place. If the knobs are placed very- near each other, so rapidly do the sparks pass, that the effect produced is very like that obtained from a mild faradic current. Thus, by an arrangement of the machine which can be done on the instant, the actions, heretofore only obtainable from the faradic machines, are readily procured from the statical electrical instrument. Besides the effectiveness of this method, it has the advantage that it is almost pain- less. In no other way can strong muscular contractions be induced with so little pain, at least. Magnetism. Magnets are natural or artificial. The former consist of a native iron-ore possessed of the magnetic property ; the latter are pieces of steel in which the magnetic property has been induced. This magnetic property consists in the power to attract pieces of iron and steel, in maintaining a certain fixed position when suspended to move freely, and in attracting or repelling the extremities of other similar magnets. A magnet suspended, free to move, always points in a certain direction, north and south. That end pointing north is the "marked" extremity, because it has a mark, notch, or groove, or the letter JV, to indicate it. Because of this property, the mag- net is said to have "poles," or polarity. The poles behave toward each other in a certain definite way : Unlike poles attract ; like poles repel, is the law. When a bar-magnet is made to approach a mag- netic needle moving on a pivot or suspended, there ensues attrac- tion or repulsion, according to the polarity of the extremities approximated. When a certain prox- imity is attained, yet some distance short of actual contact, the magnetic influence is exerted, and at- traction or repulsion, according to the pole, takes place. If a bar of soft iron, not magnetized, is sus- pended, on the approach of a permanent magnet, the former is seen to move toward the latter when they are approximated. The magnetic force is thus ex- erted through an intervening space : inversely as the square of the distance, is the law, which expresses this action in mathematical form. To this property is applied the term magnetic induction. When the soft iron is acted on by a sufficiently powerful mag- net, it ceases to be in a neutral or unexcited state, the magnetic property is induced in it, and for the time being it assumes the polar condition ; but not possessing the coercitive property — i. e., the prop- erty to retain the magnetism induced in it — soon returns to its former neutral condition. Steel, having the coercitive property, is the ma- terial out of which permanent magnets are made. The magnetic prop- Fig. 2.— Compound Magnet. 362 EXCITO-MOTORS. erty is induced in such pieces of steel by the contact of other permanent magnets. When once induced, the magnetic property may be readily destroyed by a powerful blow, by repeated scratching, and by heating. When a magnet is broken into several fragments, each piece has the same polarity. The forms of magnets are the bar and horseshoe, chiefly — the latter being more convenient, and also better retaining its power, because an armature can be kept in position. A compound horseshoe magnet is usually preferred for medical use, because of the proximity of the poles, but the straight form (Fig. 2) is also used. Galvanism. All chemical action is accompanied by electrical phenomena. The electricity furnished by the galvanic combinations in use is derived Fig. 3.— Galvanic Battekt. from a chemical action which takes place in the elements. These are of various forms. Reduced to its simplest condition, a galvanic combination consists of two substances, one of which can be acted on chemically, while the other has merely the conducting property ; and also of a material — a fluid, usually — which can excite the chemical action. There is, then, a generating plate or element, usually of zinc, a conducting plate or element of copper or car- bon, usually, and a fluid or semi-solid which acts on the zinc, setting up the chemical action. When such ele- ments with the exciting fluid are placed in a glass or earthen vessel, the whole combination is called a galvanic cell or couplet, and when several of these are united they form a battery (Fig. 3). Galvanic cells may have a single or two fluids : the single fluid is not constant ; in the two-fluid, there are arrangements, partly mechan- ical, chiefly chemical, for securing constancy in the current. In Fig. 4 Fig. 4.— A Cell. ELECTRICITY. 363 we have two metals — zinc, z, and copper, c — united by the wire, M, placed in a glass vessel containing dilute sulphuric acid. The chem- ical action in such a cell consists in the formation of the sulphate of zinc, the water being decomposed, and hydrogen appearing at the surface of the copper. Such an arrangement may be denned to be a means of making a difference in potential between two points. Elec- tricity flows from the higher to the lower potential. The point where the chemical action is taking place — the surface of the zinc — is the higher potential, and hence "the current" passes from this through the liquid to the lower potential, the copper, which is the conducting plate. Now, as the current always flows from the higher to the lower potential, it follows that, outside of the element, the copper becomes positive and the zinc negative, for the current passes through the " conjunctive wire " from the former element to the latter. It follows that such an " element," or " cup," can not furnish a constant current. The chemical action soon rises to the maximum, the sulphuric acid combines with the zinc, and hence the exciting fluid is soon nothing more than a saturated solution of zinc sulphate, while the hydrogen accumulates on the copper plate. The chemical action, therefore, quickly subsides, and the hydrogen-bubbles hinder the passage of the current by the conducting plate. Elements of this kind are usually employed to run faradic machines, but they are not suited for gal- Fig. 5.— Daniell's Element. vanic batteries, since the tension of the current varies so much in a short time, and the action soou ceases. The two-fluid cells, in which the chemical action is less violent, and mechanical devices prevent the polarization of the hydrogen, are 364 EXCITO-HOTORS. alone suited to medical uses. Only those ascertained by experience to be adapted to medical purposes can be referred to. One of the ear- liest two-fluid cell batteries constructed was that of Daniell (Fig. 5). The arrangement of the parts in this cell will illustrate the principles concerned in such galvanic combinations. The zinc and copper ele- ments and the two liquids are separated by a porous cup of unglazed earthenware. The zinc, z, is outside, and is a cylinder having a cleft ; about it is diluted sulphuric acid (1 part to 16 of water). The copper, c, is contained in the porous cup, and is surrounded by a saturated so- lution of copper sulphate, which is kept at the point of saturation by a quantity of the crystals packed around the copper element. The polarization of the hydrogen is prevented by chemical means, for in the decomposition of copper sulphate the hydrogen combines with oxygen to form water, while metallic copper is deposited on the copper element. The Daniell, as modified by the celebrated Dr. Remak, of Berlin, has been more widely used for medical purposes than any other cell, and still maintains its superiority. In this arrangement made by Siemens and Halske, of Berlin, and known under their name, besides the porous cup, a quantity of papier-mache, or paper-pulp, is packed tfTfctTtfyj* . — Bunsen Cell. in between the elements, and, while the copper is surrounded by cop- per sulphate in solution, only water is used with the zinc. In the de- composition, copper is deposited on the copper element and sulphuric acid diffuses through into the zinc compartment. This cup is remark- able for the uniform tension of the current, for constancy, and for economy. A " gravity battery," composed of zinc and copper elements, ELECTRICITY. 365 zinc sulphate solution about the zinc, and copper sulphate solution about the copper, and separated merely by the specific gravity of the respective solutions, is now much employed in telegraphy, and to a considerable extent in medical practice. Zinc and carbon are now utilized in two-fluid as in one-fluid cells. The Bunsen combination is a most efficient one (Figs. 6 and 7). The outer zinc plate has a Fig. 7.— Btjnsen Battery. cleft, and is immersed in dilute sulphuric acid, while the carbon, of the variety known as gas-carbon, is contained in a porous cup with strong nitric acid. Here the hydrogen is intercepted by the nitric acid, ni- trous-acid fumes are given off, and sulphate of zinc is formed. It is a very powerful combination, but the fumes of nitrous acid make it very objectionable. Although it is not suited for medical use in gen- eral, it is well adapted for galvano-caustic purposes. Mr. De la Rue's chloride-of-silver battery is admirably well arranged for forming a portable or permanent combination for the medical electrician. It may be made of test-tubes, closed with a rubber stopper containing two orifices for the elements, which consist of a zinc rod and flat- tened silver wire. At the bottom of the tube is placed some chlo- ride of silver, and above this a solution of common salt. The silver element dips down into the chloride of silver, and above this is in- sulated by sheet gutta-percha. This cell has an electro-motive force a little more than the Daniell, and it is remarkably constant, portable, and unchangeable. A very efficient and at the same time economical cell can be constructed of a tin can, iron filings, a porous cup, and a rod of zinc. In the porous cup, about the rod of zinc, is put some common potash, and the iron fillings which form the positive element are packed around the porous cup. Besides the above, mention should be made of the two-fluid bichro- mate of potash cell. A solution of the bichromate in dilute sulphuric acid is now chiefly used as the exciting fluid in single-fluid cells ; but, in the two-fluid arrangement, the carbon element is placed in a porous cell containing a saturated solution of bichromate of potash in water 366 EXCITO-MOTORS. only, and the zinc element is acted on by very dilute sulphuric acid (1 to 20). The performance of this cell is in a high degree satisfactory. The carbon in this, as in the other galvanic cells, is gas-carbon, which is remarkable for its density and for conducting power. The zinc is ordinary commercial zinc, amalgamated. The process of amalgama- tion consists in first immersing the zinc plate or rod in dilute sulphuric acid to make a clean surface, and then rubbing it with a little mercury until it presents a silvery whiteness. A homogeneous surface is thus made, and the loss of power due to the formation of innumerable couplets of zinc with the impurities contained in it is thereby pre- vented. The force generated in the cup by the chemical action is termed electro-motive force, and it is the difference in potential between the two elements. The power of any combination of cups is the sum of the electro-motive force of each one less the difference caused by re- sistance in the circuit. The current from a battery has strength, ten- sion, and quantity. The strength is the amount transmitted in the unit of time, along a given conductor ; tension is the power to over- come resistance ; and volume is the net quantity available. There are various objects which offer resistance to the passage of the current. The circuit of a galvanic battery consists of the space between the elements in the cup, the conducting element, and the wire which unites the poles — the conjunctive wire. The current passing over this circuit has to overcome the resistance opposed by these several parts. The conjunctive wire offers a degree of resistance determined by its length and section. A single large cup, having zinc and carbon elements of corresponding size, excited by bichromate solution, will heat to red- ness, even volatilize a platinum wire, while twenty small medical-bat- tery cups connected in series will scarcely warm such a wire. Inten- sity, resistance, and quantity, are now given a mathematical mode of expression. The unit of electro-motive force is the volt, in honor of Volta, and is very nearly the power of a Daniell cell, which is, hence^ convenient as a standard of comparison. The unit of resistance is the ohm, so named from the discoverer of the celebrated law. The unit of intensity is the ampere, formerly the weber, both the names of physicists, distinguished in electrical science. An ampere represents the quantity of electricity produced by the unit of electro-motive force — the volt — circulating in a conductor having the unit of resistance — the ohm — during the unit of time — the second. It has been practically ascertained that this is the quantity of electricity furnished by a Daniel! cell, and made to pass through a hundred metres of telegraph-wire. The unit of capacity is the farad, from Faraday ; but, as this amount is much too large for medical purposes, it is the usual practice to em- ploy the term microfarad, which is equal to one millionth part of a farad. ELECTRICITY. 367 There are several modes of ascertaining the current strength. The voltameter (Fig. 8) is an instrument for collecting the oxygen and hydrogen produced by the decomposition of water. The quantity of gas per minute evolved by the gal- vanic action is an absolute measure of the strength of the current dur- ing that time. This instrument, although not so much used as the galvanometer for determining cur- rent strength, is not without prac- tical utility, and it is employed by Ciniselli and others to ascertain the power of any given combination be- fore proceeding in the operation of electrolysis in the treatment of aneu- rism. Galvanometers are more frequently used. A galvanic current made to traverse a wire, in the vicinity of a magnetic needle, deflection takes place according to the strength and direction of the current. This constitutes the simplest form of the galvanometer. It is really a galvanoscope, indicating the existence of a current and its direction, but not affording an exact measure of its strength. The astatic com- bination is much more sensitive : it consists of two needles of about the same strength, but placed in opposite positions as to polarity, so that the directive force of the earth's magnetism is neutralized (Fig. 9). The arrangement of an astatic galvanometer is shown in Fig. 10. To Fig. 8.— Voltameter. 6 i Fig. 9.— Galvanometer. Fig. 10.— Galvanometer. render such a galvanometer of use as a means of exactly representing the strength of the current, the scale must be graduated in mille-am- peres of absolute measurement, or millewebers. Such instruments, as now made, enable the operator to express in exact terms the current 368 EXCITO-MOTORS. strength ; instead of the number of cups, which affords so inexact a measure, the absolute galvanometer interpolated in the circuit, indi- cates in mille-amperes, or millewebers, the actual strength. In the present condition of this subject, it has become necessary to express in an exact way the current strength, just as medicines are carefully weighed. * The mode of combining the cells of a galvanic battery is determined by the purpose to which it is to be applied. The circuit may be " sim- ple " or " compound." In the former, the elements are united zinc to zinc and copper to copper, so that in a battery of twenty cells so united there is one large zinc and one large copper element, and the resistance is at the minimum, the chemical action yielding a very considerable quantity of electricity, the most of which is available. In the compound circuit the battery elements are arranged in series, the zinc of one connected with the copper or carbon of the next, and so on throughout the whole number. As every conductor opposes some resistance to the passage of the current — in other words, there is no perfect conductor — there must be considerable loss of electricity. It is sometimes said that the quantity of electricity is determined by the size of the zinc plates acted on, and that intensity is the result of combining numbers of elements. It must be understood that intensity is the power to overcome resist- ance, and as the resistance offered by the human body is enormous, it follows that a battery for the medical application of galvanism must have numbers rather than size. Those battery-cells furnish the smooth- est current in which the internal resistance is about equal to the resist- ance of the human body. The zinc-carbon elements of Stohrer cause considerable irritation and burning, while those of Siemens and Halske are smooth and bland. The most experienced electricians use the latter for this reason. It follows, therefore, that all those devices in- tended to diminish internal resistance are not to be commended in gal- vanic batteries for medical use, how desirable soever they may be in batteries for economic purposes. In galvanic batteries intended for transportation, every consideration, except efficiency, must be sacrificed to portability, and various mechanical arrangements have been made to combine these qualities. In the Stohrer, Gaiffe, and chloride-of- silver batteries, the safe transportation of the cells is insured, but the current of such combinations is wanting in the uniformity and smooth- ness which are such important qualities in the permanent batteries. The performance of any galvanic combination may be readily as- certained by the law of Ohm. The intensity is directly proportional to the electro-motive force, and inversely proportional to the resist- ance encountered within the cell and on the circuit. This law is rep- resented in the following formula : R + r ELECTRICITY. 369 I is the symbol for intensity, E for electro-motive force, R for internal resistance (in the cup), and r for external resistance (on the circuit). E Or it may be stated that R = -~ ; that is to say, the resistance equals the electro-motive force divided by the current. The term electro- motive force merely means the difference in potential between the two poles. A battery, whether portable or permanent, requires a "pole-board" for its working. An ordinary battery of a few elements may be manip- ulated by a simple sliding selector and polarity changer, such as that now attached to the Stohrer portable arrangement ; but the permanent batteries of large size, such as are now employed for the office and con- sultation rooms of medical electricians, require more efficient arrange- ments. The battery of 60 to 100 elements placed in the cellar or some distant closet, is connected, in groups of cells, with the pole-board. By means of the selector, any desired number of cells can be put in the circuit. The pole-board should also be supplied with a current- changer, a rheostat, an interrupter, and resistance-coils. A water rhe- ostat suffices for ordinary purposes. As water is an indifferent con- ductor, it follows that the galvanic current has a degree of difficulty in passing through it ; hence, any amount of resistance can be interpo- lated in the circuit. The most accurate mode of introducing a meas- urable resistance is the resistance-coil. This is made of German-silver wire of a certain length and cross-section. The resistance offered by such a wire to the passage of the current is directly as its length, and inversely as its sectional area ; that is, the longer the wire, and the less its size, the more the resistance to the transmission of the current. The unit of resistance, the ohm, is the resistance made to one volt by a wire two hundred metres in length. It is obvious that any number of ohms in resistance can be interpolated in the circuit. Resistance- coils of definite measures of resistance are now added to each properly equipped pole-board. They are especially necessary in applications of galvanism by the polar method. Faradism, or Electro-Magnetism and Magneto-Electricity. Faradism, so named in honor of Faraday, is induced electricity. When the galvanic current passes through the conjunctive wire of the elements of a cup, especially of a battery, it acquires new properties — acts on a magnetic needle, and exhibits the other properties of a mag- net. When the conjunctive wire is extended into a coil, coated with insulating material, it will act on another coil in its neighborhood, as it does on a magnet. The former is called the primary or inducing coil, and the latter the secondary or induction coil. If the latter is con- nected with a galvanometer, it will be found that when a current trav- erses the primary coil, the needle of the galvanometer is at once 24 370 EXCITO-MOTORS. deflected ; but if the current continue to pass without any variations in the tension, the needle presently conies to rest. When the current is broken or interrupted, the needle is again deflected, but this time in the opposite direction. It follows, therefore, that the induced cur- rent only occurs at the opening and closing of the primary circuit : at the making or closing the circuit, in the opposite direction ; and at the opening or breaking of the circuit, in the same direction. The induced or faradic current is therefore a to-and-fro current, instantaneous in duration. It is obvious from these considerations that in the construc- tion of a faradic battery there must be a mechanical arrangement for interrupting the current in the primary circuit. The usual automatic interrupter is Neef's hammer, a vibratile steel spring worked by the magnetism of the soft-iron core. The best instruments are now pro- vided with a simple mechanism to give slow interruptions, an impor- tant matter when muscles are to be exercised. In the purchase of a faradic instrument for medical purposes the device to effect the slow interruptions should not be overlooked. The galvanic couplet for the primary coil is now almost always the zinc-carbon combination excited by bichromate solution.* The pri- mary or inducing coil is made of thick wire and is much shorter than the secondary coil. In the interior of the primary coil is placed a bundle of wires, each one insulated and becoming a magnet when the current passes. This temporary magnet attracts the hammer of the Fig. 11.— Ruhmkorff Coil,. vibrator, and on the instant the current is closed and opened again. The so-called primary current of the faradic battery is therefore some- * The bichromate solution is prepared as follows : Dissolve one ounce of bichro- mate of potassium in eighteen ounces of hot water in an earthenware vessel. Let it cool, and when cold add two fluid ounces of sulphuric acid, and two drachms of nitric acid. It should not be used until cold, and it is, therefore, preferable to keep it on hand. ELECTRICITY. 371 thing more than that coming from the galvanic couplet ; it is re- enforced by the induction between the turns of the coil and by the magnetism of the soft-iron core. The coil of induction, or the secondary coil, is made of long and fine wire ; the longer and finer, the more intense the current. The Ruhmkorff coil, which is composed of miles of very fine wire, fur- nishes a brilliant spark sometimes several inches in length (Fig. 11). Electro-magnetism is the title of that mode of the force induced Fig. 12. by the action of a galvanic current on a bundle of wires within an insulated coil ; in other words, it is the ordinary faradic battery, ex- cited by a galvanic couplet (Fig. 12). Magneto-electricity ', on the other hand, is that mode of the force induced by the action of a per- manent magnet. If we substitute for the cell a strong permanent magnet, we learn that, on the approach or withdrawal of . the magnet from a coil of insulated wire, a current of elec- tricity is induced in the coil : on the approach of the magnet, in one direction ; on its with- drawal, in the opposite direction (Fig. 13). Thus an instantaneous to -and -fro current may be caused by the action of a magnet, just as by the action of a galvanic current. Out of this principle has developed the magneto-electric machine, which consists of the permanent mag- nets, insulated coils made to revolve about the poles, and a mechanical arrangement for ob- taining regular revolutions, and making and breaking the circuit. Thus, by mechanical power, the same results are produced as by chemical action (Fig. 14). The discovery of a simple commutator, by which the currents can Fia. 13. 372 EXCITO-MOTORS. be collected and sent in one direction, has quite revolutionized the utility of this form of battery. It is now applicable to electric decom- position (electrolysis), to electric heating (galvano-causty), and electric Fig. 14.— Magneto-Electric Machine. lighting. Indeed, with the general use of electricity furnished by the " dynamo-machines " as a motive power, it is probable that the force in this form will be successfully applied to medical purposes. Electro-Physiology. — Much of the supposed knowledge of this sub- ject is in a transition state, and will ultimately require very different statement. Into this doubtful region the author will not enter ; but there are facts of great value which should not be overlooked. Action of Galvanism on Motor Nerves and Muscles. — Whether a muscle be acted on directly by a galvanic current, or indirectly through a motor nerve which supplies it, the muscle is thrown into action ; but the action is limited to the opening and closing of the circuit if the tension of the current continues the same throughout. If the "de- scending " or " direct " current has the minimum strength to cause a muscular contraction, this will take place at the closing of the circuit only, and there will be no action at the "opening," or "interruption," or " breaking " of the circuit. A descending, closing-current muscu- lar contraction is always greater than the opening. The rule is differ- ELECTRICITY. 373 ent in the case of the " ascending " or " indirect " current. The feeblest strength of current, passing in the inverse direction, which will cause a muscular contraction, induces it only at the opening of the circuit, but, if a strong current is used, both at the opening and closing. Di- rect excitation of a muscle by galvanism causes more powerful mus- cular contractions than indirect. Such are the results of galvanic stimulation when the motor nerves are uncovered by tissues, and are directly acted on by the electrodes. If, however, motor nerves and the muscles are acted on through the tissues covering them, the most energetic contractions are induced by inverse or ascending currents, and at the closing of the circuit. When a motor nerve supplies by separate filaments two muscles, stimulation of one filament causes con- traction of the muscle to which it goes, but contraction of the other muscles also takes place. To the latter is applied the term induced contraction. If a motor nerve is stimulated again and again by a direct current, finally its excitability — that is, its power to contract on irritation — is exhausted ; then the excitability may be restored by the action of an inverse current. By thus alternating in the direction of the current, the muscular irritability may be alternately destroyed and restored for a long time, if not indefinitely. To these phenomena has been applied the term voltaic alternatives. Action of Faradism on Jfotor Nerves and Muscles. — A faradic current, whatever its direction, stimulating a motor nerve, causes con- traction of the muscles innervated by this nerve. If the interruptions in the primary circuit are slow, the muscles have time to contract and relax ; but when the interruptions are rapid, the muscles are kept in a condition of tonic contraction, or are tetanized. Long-continued, powerful faradic stimulation of a motor nerve exhausts its irritability. Muscles directly acted on by a faradic current contract energetically, but repeated over-stimulation will fatigue and ultimately destroy their contractility. When, however, muscles are in this condition of fatigue and exhaustion, from faradic stimulation, their proper functional state may be restored by passing a continuous galvanic current through them. If not too long applied or too powerful in action, faradic ap- plications improve the nutrition of muscles, and through this increased activity of the circulation there occurs a rise of temperature, generally. TJie Polar Method as applied to the Beactions of Motor Nerves and Muscles. — This important method of examining the condition of motor nerves and muscles must be understood, to rightly appreciate the modern mode of electro-diagnosis. As certain terms, having technical meanings, are much used in this connection, it is necessary to define them before proceeding to describe the phenomena. Anode is the term applied to the positive pole, cathode to the negative pole, and the adjectives, anodal, relating to the anode, and cathodal, relating to the cathode. As the polar method had its origin in Germany, the 374 EXCITO-MOTORS. symbols now used to indicate electrical reactions are taken from Ger- man words. Charcot in France, Buzzard in England, and the Ameri- can writers in general, have adopted the German formulae, so now their use is universal. The polar method consists in exciting nerve or muscle with one pole, while the other rests on some indifferent spot, as the sternum, as advised by Erb. We are here concerned with the normal or physio- logical state ; hereafter, the pathological conditions will be given. The normal formulae consist in the reactions which ensue on polar stimulation, nerves and muscles being healthy. When the current is closed by applying the cathode to the nerve or muscle to be excited, the symbols are Ka S (Ka, Kathode ; S, Schliessung, closing). When the current is opened or broken by removing or disconnecting the cathode, the symbols are Ka O (Oeff?iung y opening). Corresponding symbols are used in respect to the anode. Thus, the words anodal closing are An S, and anodal opening, An O. To express muscular contraction the symbol is Z (Zuckung) ; a strong contraction is Z' ; for a weak contraction, z, and for a tetanic contraction, Te. In the physiological state, the muscular contractions as induced by the polar method are characteristic, and can be expressed in the symbolic language now employed for the purpose. It is to be observed, in the first place, that the cathode or negative pole has more power to induce muscular action than the anode or positive pole. The cathode has more effect on closing the circuit ; whereas the anode acts more powerfully on opening or breaking the circuit. The normal formulae of muscular contractions induced by the polar method may be arranged in three grades : In the first grade, the weakest current having power to induce any contraction causes it on cathodal closing — whence the formula Ka S Z ; and no action takes place from the anode. In the second or intermediate grade, the strength of current is sufficient to cause strong cathodal closing contraction (Ka S Z ; ), but no opening contraction ; whereas, on anodal opening and closing there are feeble contractions — whence An S z, and An O z. In the third grade, which is the highest, the current causes on cathodal closing a tetanic contraction, Ka S Te, and a feeble contrac- tion on cathodal opening Ka O z ; whereas, there occur decided con- tractions on anodal opening, An O Z, and on anodal closing, An S Z. Such are the normal formulae — such is the normal behavior of muscles ; but in disease, as we shall subsequently learn, these formulae may be much changed, may be even entirely reversed. Action of Galvanism on No7i-striated Muscles. — The physiologi- cal differences in the action of voluntary and organic muscular fibers are well exhibited in the results of galvanic stimulation. Instead of a prompt, almost instantaneous muscular contraction, characteristic of ELECTRICITY. 375 the voluntary fiber, a slow vermicular motion is set up in the involun- tary, and this movement is propagated from the point of stimulation by a rhythmical action. Action of the Galvanic Current on the Brain and Spinal Cord. — Until the experiments of Fritsche and Hitzig, Ferrier, Nothnagel, and others, within a few years past, the electric excitability of the brain had not been admitted. It seems now to be established that certain areas of the cortex cerebri are anatomically associated with certain muscular groups. These facts have been ascertained by direct stimulation of these areas of the cortex by galvanic (Fritsche and Hitzig) and faradic (Ferrier) applications. Can the intra-cranial or- gans be reached through their investing tissues ? This is the most im- portant question, and to this, fortunately, we are able to reply in the affirmative. Erb was the first to prove the transmission of a galvanic current through the brain, and now the fact is universally admitted. On electric stimulation of the cord, results are produced accord- ing to the functional powers of the part — pain when the sensory tract is irritated, and muscular movements when the motor is acted on. Hence, the statement of Erb, that these effects may be due to stimula- tion of the nerve-roots, has a high degree of probability. In the spi- nal cord, as in the nerves, the inverse or ascending current causes more decided effects. Electric excitation of that part of the cord between the fifth cervi- cal and tenth dorsal vertebrae causes dilatation of the pupil, whence this region is known as the cilio-spinal region. The explanation of this fact is, that in this part of the cord originate filaments of the sympathetic, connected with the cervical ganglia. In the lumbar part of the cord is a similar center, related to the genital apparatus, and hence called the genito-spinal region. Action of the Galvanic and Faradic Currents on the Pneumogas- tric. — A weak galvanic current sent through the pneumogastric, in- creases the force and rapidity of the heart's movements ; but a strong current arrests the heart in the diastole. After division of the nerve, stimulation of its upper or central portion arrests respiration in the movement of inspiration, but does not influence the heart ; but a strong current acting on the lower or distal portion of the nerve stops the heart in diastole. A descending galvanic current, passed through the pneumogastric nerve, suspends the contractions of the stomach. A faradic current directly applied to the pneumogastric, before and after division of the nerve, produces the same results, but more decid- edly ; applied through the tissues, it has no apparent effect. Action of Galvanism and Faradism on the Sympathetic System. — Covered by the tissues, the ganglia and fibers of the cervical sympa- thetic are not acted on by faradic and static electricity, but even a weak galvanic current does affect them. Applied directly to the sym- 376 EXCITO-MOTORS. pathetic nerves, the effect is tetanizing, and the vessels receiving their innervation from this source contract very strongly. Applied through the tissues, the faradic current has little or no effect. The kind of action set up by galvanism, and the differences due to the direction in which the current is passing, have been much disputed. The author believes that the experiments and the deductions of Oni- mus and Legros correctly represent the actual condition. They hold that the direct or descending current, by increasing the normal wave- like or vermicular motion of the muscular layer of the vessels, increases the amount of blood passing through them, and that the inverse or ascending current, by diminishing the vermicular movement, lessens the quantity of blood. Electro-Diagnosis. — For diagnostic purposes both galvanic and faradic currents are necessary. The polar method has been applied with great success for determining the condition of nerve and muscle. As has been stated, the pole intended for excitation must be placed over the nerve or muscle to be acted on, while the other rests on some in- different point — for the upper extremity and trunk, the sternum is convenient. If the operator has no assistant, an interrupting handle of the electrode is useful, or an automatic interrupter may be attached to the pole-board, or the interruptions may be effected by simply ap- plying or removing the electrode. The normal formulae of nerve and muscle actions have been set forth ; in disease these formulae are altered — may be, even entirely reversed. It suffices now to state that when a faradic — an induced — current is applied to a muscle, or to the motor nerve supplying it, con- traction of the muscle takes place. This is called faradic excitation, and it is direct when the contraction is caused by application of the electrodes to the muscle itself, and indirect when the motor nerve is acted on. When galvanism is used to produce these effects, the term applied is galvanic excitation, and this is direct or indirect. The Diagnosis of Paralysis. — When the paralysis is limited to a group of muscles, to one member, or to one side, the behavior of the paralyzed muscles is compared with the normal. If, however, as is comparatively infrequent, symmetrical muscles are paralyzed, their condition must be contrasted with that of another healthy subject. The paralysis of muscles may be complete, and yet they react in a normal manner. In other cases, there may be merely quantitative changes ; that is, there is a mere increase or diminution of electric excitability, the polar reactions conforming to the normal, in order. In the third group, the paralyzed muscles are found to be changed, not only quantitatively but qualitatively, in respect to their responses to the electrical excitation. If the muscles respond in a normal man- ner to both forms of current, it may be concluded that the spinal cord connected by nerve-fibers to the paralyzed part is free from disease. ELECTKICITY. 377 The changes in respect to the electric excitability, in some cases of paralysis, consist merely in a quantitative increase to both currents : the muscles react to a less strength of current, or more energetically to the same strength. In the latter, while the normal formula is de- veloped by acting on the healthy muscles, on the paralyzed side the reaction is more decided, as indicated by a cathodal closing contrac- tion (Ka S Z) occurring with a very weak current, or Ka S Z becoming, on the application of the same current, a tetanus (Ka S Te) ; also indi- cated by the early appearance of an anodal opening contraction (An O Z) and the prompt appearance of a cathodal opening contraction (Ka O Z). A hemiplegia of recent occurrence, some cases of spinal paralysis at a very early stage, and very rarely the earliest manifestations of pa- ralysis from nerve-lesions, are illustrative of this state. The usual condition for which the electrical currents are employed in diagnosis is diminution or loss of electric excitability. Spinal, motor-nerve, and muscular lesions are the most important. " Reac- tions of degeneration " is the happy term employed by Erb to signify the changes in the electrical reactions. Owing to disease of the cord, or of the motor-nerve trunks, degenerations of tissue ensue, and hence the term. For a very brief period, in some cases, there is an increase of electrical excitability, but a decline then quickly ensues. As re- gards faradism, the strength of current necessary to cause a contrac- tion of the affected muscles must be constantly increased, and in a short time no strength of current will cause the least movement. The normal formula for the galvanic current is changed, pari passu, with the decline of faradic excitability. First, the cathodal closing tetanus ceases (Ka S Te), then anodal closing contraction (An S Z), and finally cathodal closing (Ka S Z) can be excited only by the strongest cur- rent. These changes represent a gradually increasing atrophy of the muscles, and the final cessation of the cathodal closing contraction signifies an extreme degree of atrophy, and the disappearance of the muscular elements. In the condition known as the reactions of degeneration, it is im- portant to distinguish between the reactions of the motor nerve and of the muscles. It has been already pointed out that, whether the mo- tor nerve supplying it, or the muscle itself is acted on, muscular con- tractions take place. In the changes which ensue in cases of paralysis, the state of the nerve is separable from that of muscle. If the paral- ysis is due to a lesion of the nerve-trunk — to an inflammation of the nerve, for example — there may be a brief period when, as above stated, the electric excitability is heightened ; but, as the nerve undergoes de- generative atrophy, there ensues a quantitative decline in the response to electrical excitation, to both faradic and galvanic, and by the twelfth day, sometimes earlier, it has usually entirely disappeared, if the le- sions have proved destructive and irremediable. On the other hand, 378 EXCITO-MOTORS. \ if the injury done is less, and is remediable, the electric excitability is modified only, and not lost. When recovery from the injury, or in- flammation of the affected motor nerves takes place, the muscles inner- vated will respond to the impulses of the will, long before they react to faradic or galvanic stimulation. When the spinal cord is the seat of disease, as in infantile paralysis, glossolabiolaryngeal paralysis, progressive muscular atrophy, etc., the paralyzed nerves and muscles exhibit most characteristic electrical re- actions. As regards the motor nerves, in two or three days, usually, after the paralysis has manifested itself, a regular and steady quanti- tative decline in excitability to both forms of current takes place, and by the end of the second week, usually, and sometimes by the end of the first week, no strength of current applied to the nerve will cause muscular contractions. At first, cathodal closing ceases, then anodal closing, and finally anodal opening. The muscular reactions are much changed from the normal. The muscles, in about a week after the paralysis appears, begin to decline in their excitability to the faradic current, and, at the end of two weeks, it is totally lost, and they cease to respond to any strength of application. If regeneration of the diseased nerve-tissue can be effected, restoration of the faradic excitability may be accomplished, but to a less extent than before. The phenomena connected with the galvanic excitability are very different. For the first week of the paralysis the response of the mus- cles to the galvanic current declines, as it does to the faradic ; but, after the second week, a remarkable change ensues : then the galvanic excitability begins to increase, and with this there occur qualitative changes in the order and mode of muscular contractions. These con- sist in a gradual increase of the anodal closing contraction, which soon equals if it does not surpass the cathodal closing, and the cathodal opening contraction declines in the same measure. In other words, an actual reversal takes place of the normal formulae. If the degenera- tions continue, and the muscular elements are finally destroyed, the reactions ultimately cease, the last to disappear being a very feeble anodal closing contraction. Such are the reactions of degeneration. They occur in cases of spinal paralysis, when the disease in the cord is in direct anatomical association with the paralyzed parts, and in cases of peripheral paralysis when due to injury or disease of nerve- trunks. The so-called infantile paralysis is an illustration of the for- mer, and facial paralysis of the latter. When the disease is situated in the cord above the point from which nerves are given off to the paralyzed members, there is no change in the law of muscular contrac- tion. When, for example, a transverse myelitis exists entirely above the dorso-lumbar enlargement of the cord, the muscles of the lower extremities, although paralyzed, react normally to the faradic and ELECTRICITY. 379 galvanic currents. Again, in disseminated myelitis there are groups of muscles that react in accordance with the law of normal contrac- tion, and other groups that manifest the reactions of degeneration — the former being in anatomical connection with a healthy part of the cord ; the latter with a diseased area. It follows, therefore, that a proper electrical examination should be made as a means of diagnosis in the diseases of the nerve-centers. Diagnosis of Sensibility. — By means of the faradic brush, and pointed electrodes closely approximated, the state of sensibility of the skin may be readily marked out. The skin must be carefully dried to prevent diffusion of the current, and then the brush or electrodes conveying the induced current must be carefully passed over the sup- posed anaesthetic and analgesic area, and the outlines of the affected surface thus ascertained. The galvanic current by the polar method has been very success- fully applied to determine the state of the auditory nerve. The pole intended for excitation is introduced through a suitable non-conduct- ing speculum into the ear, previously filled with warm water, and the other pole is placed on the mastoid process, nape of the neck, or any indifferent point. Brenner, of St. Petersburg, who has contributed the most of the exact knowledge now in our possession regarding these auditory reactions, has invented resistance-coils to be utilized in these researches. A strong current, reduced to the necessary point for act- ing on the auditory nerve by the introduction of sufficient resistances, is passed through the organ, and the resulting sounds, subjective, and audible, of course, only to the patient, indicate the condition of the nerve. These sounds, whistling, singing, roaring, etc., have been re- duced to formulated expressions. Although there are differences of opinion in regard to the real value of these auditory reactions, it seems to be now well established that Brenner's method and formulae are correct in the essential details. The state of gustatory sensibility is most correctly ascertained by galvanic stimulation of the end-organs of the nerve. For this purpose a pointed electrode, the positive and negative as closely approximated as possible, is carefully passed over the area of distribution of the sense of taste, and its condition noted. Feigned paralysis may sometimes be detected by faradic stimula- tion of the muscles, and feigned insensibility by a strong current. Hysterical paralysis is remarkable for the absence of electro-sensibility and the presence of electro-contractility. Therapy. — Manipulation. — Electrodes for the application of gal- vanism or faradism are of various shapes and materials. The best, probably, is a disk of carbon covered with wash-leather. A metal disk covered with soft sponge is also much used. The size depends on the purpose to which applied. When large volume and high in- 380 EXCITO-MOTORS. tensity are the qualities of the current, the electrode should be of large size, of soft sponge, well moistened. For application to small muscles, Duchenne's olive-shaped, curved electrodes are most suitable ; and to individual nerves, metal buttons of various shapes covered with wash- leather. The instrument-makers are now supplied with all forms and kinds of electrodes, so that the operator can always obtain what form of electrode soever he may desire. When it is intended to act on parts beneath the skin, the electrodes and skin should be well moistened, for the conductivity of the tissues is in direct ratio with the amount of water they contain. On the other hand, if the skin alone is to be acted on, it should be well dried to pre- vent diffusion of the current. When weak galvanic applications are made, but little tingling is felt by the patient, and hence he may sup- pose that no curative effect is produced. Under such circumstances, it were better to add a little salt to the water with which the electrodes are moistened. Electrical applications should always be made to the affected part, and also to those parts in which decided symptoms are felt. The principle of localized electrization, as established by Duchenne, was a most important advance. Next, the polar method did much to give exactness to methodical applications. When the poles have a fixed position, and are not moved, the application is said to be stabile, and, when moved over the part operated on, labile. If the direction the galvanic current is taking is parallel to the nerve-current, or from the center toward the periphery, the application is said to be direct, or descending ; if in the opposite direction, indirect, or ascending. General electrization is a term used to indicate the application of either current to the whole surface of the body — one pole placed on the nape of the neck, or to the feet, and the other passed over the whole surface of the body. Centred galvanization is a term invented by Beard and Rockwell to signify applications to the cervical sym- pathetic, to the pneumogastric, to the cervical and dorsal parts of the spinal cord, and to the solar plexus. If one pole be placed on the seventh cervical vertebra, and the other in the fossa behind the angle of the jaw ; if the former be kept in this position, and the latter put on the epigastrium ; and, lastly, if the first be moved down the spine to a point opposite the second — there will be brought into the circuit, successively, the ganglia of the cervical sympathetic and their cardiac branches, the pneumogastric, spinal accessory, phrenic, the semilunar ganglion and solar plexus, and the spinal cord. In what mode soever applied, and at what point, more or less dif- fusion of the current takes place. Although the current flows from the higher to the lower potential by the most direct route, a greater or less deflection is caused (diffusion) by the resistance encountered on the circuit. ELECTRICITY. 381 Magneto-Therapy. — The force furnished by the magnet — mag- netic polarity — produces distinct effects when applied to plants and to animals, and it has been utilized in the treatment of diseases. It has been shown by Dr. Vansant that the south pole of the magnet ap- plied to a sensitive surface causes pain, while the north pole is free from this action, and indeed relieves the pain caused by the former. Small animals are similarly affected, the south pole causing excite- ment, and the north pole sedation. Sometimes remarkable curative results are obtained by the application of magnets in neuralgia and in chorea ; but they often fail utterly. In hysterical affections, hemi- anesthesia^ contractures, etc., the results are more constant, and, in- deed, are often very striking. It is quite impossible to separate the influences due to the imagination from the direct action of the magnet. The form of magnet used in medical practice is chiefly the horse- shoe, and, to obtain sufficient power, several permanent magnets are clamped together. The magnetic pole with which the effect is in- tended to be produced may be gently stroked along the course of the nerve in cases of neuralgia, or the magnet may be fastened on the part by suitable straps. The duration of the application will be determined by the effects. In some cases the result is little short of magical ; in others, apparently of the same character, no effect follows. Galvano - Therapy. — The most important curative results are wrought by galvanism. As a rule, the large, two-fluid elements of the permanent battery are much more effective therapeutically than the small portable combinations. In the Siemens and Halske modifica- tion of the Daniell cup, which is so much employed by German electro- therapeutists, and which the author also uses, the resistance within the battery is very great, nearly equal, indeed, to the resistance of the body. Hence, the current is smooth and uniform, and hence, also, the good results obtained from it. Allbutt made a number of experimental observations at the West Riding Lunatic Asylum on the therapeutical effects of electricity (gal- vanism) in psychical disorders, and he sums up his results as follows : Marked improvement in acute primary dementia ; distinct improve- ment in mania, atonic melancholia, and perhaps recent secondary de- mentia ; no change observed in chronic dementia and some cases of melancholia, and an unfavorable effect in hypochondriacal melancholia, and perhaps brain-wasting. In the cases reported by Allbutt, the cur- rent was sent through the head and through the cervical sympathetics. Benedict (page 222) reports three cases of mental disorder improved by galvanism. I have observed excellent results in the mental and other symp- toms — confusion of mind, impaired memory, hypochondriasis, vertigo, etc. — which result from imperfect nutrition of the brain, caused by atheromatous degeneration of the cerebral vessels. My method of 382 EXCITO-MOTORS. application has consisted in transverse transmission of galvanism through the brain, using a current of sufficient intensity merely to cause slight giddiness, a faint metallic taste, and barely perceptible flashes of light. Galvanization of the brain and of the cervical sympathetics is one of the measures to be resorted to in acute active or passive congestion of the brain. Wakefulness, when not reflex in origin, and when de- pendent simply on the state of the vascular supply, is often relieved by galvanization of the brain. Insomnia may be dependent on either active or passive congestion. In the first case a continuous current of moderate intensity should be passed through the superior ganglion of the sympathetic — the positive pole being placed in the auriculo-max- illary fossa, the negative on the seventh cervical vertebra ; in the second case a mild current should be transmitted transversely through the brain, and be slowly interrupted. To promote absorption of the clot in cases of cerebral hemorrhage, and to relieve the collateral oedema in embolism of the cerebral arte- ries, very mild galvanic currents may be employed. Caution is neces- sary, however, in employing galvanism in such cases. Strong currents and lengthened applications may do serious mischief ; but the author believes, with Remak, that judicious application of galvanism will be useful. The immediate effects of the embolism, or of the haemorrhage, should be allowed to subside before commencing the use of electricity, and, if there be much headache and vertigo, the greatest circumspec- tion will be necessary. In hemiplegia the constant current may be applied to the brain, for the purpose of improving its nutrition, and the faradic or induced current to the muscles, to prevent wasting and loss of function from disuse. If the temperature of the paralyzed parts is lowered, the skin discolored and roughened, the muscles weak and flabby, much im- provement in all these particulars will follow faradization. Large elec- trodes, well moistened, should be used, and all the muscles should in turn be made to contract — one pole being placed over the motor nerve, the other over the bellies of the affected muscles. In cases of hemiplegia, when the nutrition of the skin and muscles has been im- proved to the extent which faradization can accomplish, no advantage can accrue from further persistence in the applications. In faradizing the muscles in a case of hemiplegia, a current of just sufficient inten- sity to cause contractions should be used. Tetanic cramps fatigue the muscles, and are harmful. The so-called " late rigidity " — the muscu- lar contractions which ensue after a time in hemiplegia, and which occur chiefly in the forearm and hands — is best treated by a contin- uous current to the contracted flexors, and an interrupted or faradic current to the relatively weaker extensors. In recent affections of the spinal cord, as a rule, electricity is not ELECTRICITY. 383 indicated. In chronic myelitis, syphilitic diseases of the meninges, after a course of suitable speciiic treatment, and in some of the sequelae of acute meningitis, much good may be accomplished by the galvani- zation of the spine and the paralyzed muscles. The wasting of the af- fected muscles may be arrested and their nutrition raised to the nor- mal, and the paralysis of the sphincters may, in many cases, be relieved. When the electro-contractility of the muscles is not impaired, and when they have not wasted, no good is to be accomplished by stimu- lating them with the electrical current. That very troublesome disorder, spinal irritation, with its extensive irradiations of nerve-pain, is much benefited by an inverse galvanic cur- rent, according to Hammond, and this observation I have been enabled to confirm by my own experience. Hysterical paralysis of the extremi- ties, accompanied or not with anaesthesia or hyperaesthesia, should be treated by galvanization of the spine and faradization of the muscles. In paralysis from lead (dropped wrist), the muscles may be so far atrophied as not to respond to faradization, but may react when stimu- lated by a slowly-interrupted galvanic current. When this condition exists, the interrupted galvanic current must be first employed, and the cure be completed by the faradic current when the muscles are so far improved as to react to the latter. The best example of & peripheral paralysis is that of the muscles of the face, from disease or injury of the facial nerve. From exposure to cold, or disease of the ear, or traumatic injury, the nerve is damaged, and the muscles to which it is distributed are paralyzed. In accordance with the law already given, such muscles do not respond to the faradic current, but do react to galvanism. The positive pole is placed over the pes anserinus, or on the mastoid process, and the negative is made to pass over the peripheral expansion of the nerve, so that all the mus- cles innervated by the nerve are brought into action. A current of sufficient intensity to induce muscular contraction must be employed. As in the case of other peripheral paralyses, after a time the af- fected muscles recover their power of response to faradism, when this form of current may be used to complete the cure. If the nerve has not been irremediably damaged, and if the paralysis has not existed so long that the electro-contractility is lost in consequence of atrophic degeneration of the muscles, a cure of facial paralysis may be effected by a persistent use of electricity. Certain of the ocular paralyses, as of the third, fourth, and sixth nerves, are often cured by electricity (interrupted galvanic current). It is necessary, in order to obtain a successful result, that the remedy be employed in suitable cases. When these paralyses are dependent on cerebral tumors, syphilitic gummata, exostoses, etc., electricity can not be expected to cure ; but the paretic state of the muscles, left after the removal of the gummata, may be promptly relieved by galvaniza- 384 EXCITO-MOTORS. tion. The functional states of the above-mentioned nerves, of which paralysis may be a symptom, will certainly be cured by electricity. Faradism may sometimes succeed when galvanism fails in these cases (Althaus). Cases of aphonia, when dependent on paralysis of the vocal cords, are sometimes cured by a single application, and few, indeed, resist the proper use of galvanism. The larynx may be faradized externally ; the recurrent laryngeal may be galvanized by placing one rheophore over its trunk and the other over the larynx, or, what is better, an in- tra-laryngeal electrode (Mackenzie's) may be used. Paralysis of the bladder and of the sphincter ani, even w r hen symptomatic of spinal affections, may be greatly benefited, and the condition of the patient rendered much more comfortable, by an inter- rupted galvanic or faradic current applied by suitable insulated elec- trodes. Idiopathic cases of these affections may be cured in this way. Constipation, due to atony of the muscular layer of the large intestine, can be overcome by the same means. An insulated electrode is intro- duced into the rectum, and a large sponge-covered rheophore, well moistened, is passed over the abdomen so as to bring every part of the large intestine within the circuit. The failure of respiration in opium narcosis can be most success- fully obviated by faradization of the muscles of respiration. A strong faradic current is one of the most effective means of causing uterine contractions in cases of post-partum haemorrhage. In certain of the " myopathies of spinal origin" but not in all of them, electricity gives excellent results. The most decidedly curative results are obtained in infantile paralysis. The electrical treatment should be begun early, but after the subsidence of all inflammatory symptoms. Good results may be looked for if the electro-contractility of the muscles is not lost, and if important changes have not occurred in the joints. In many cases the affected muscles, although not atro- phied, do not respond to the faradic current, but will to the interrupted galvanic. The latter should therefore be used until the muscles are put into a condition to respond to the former. Besides galvanization and faradization of the paralyzed muscles, the electrical treatment should include galvanic spinal-nerve and plexus-nerve currents. Thus far but little benefit has accrued from the electrical treatment of pro- gressive muscular atrophy. If the initial change in this malady were myopathic (as asserted by Friedreich), good results from localized faradization might be obtained. The author's most recent experience as to the curability of this disease by electricity is not in accord with Onimus and Legros's, who declare that it is without avail in this dis- order, for it does appear to have the power, in some instances, of arresting its progress. Posterior spinal sclerosis is sometimes retarded in its course and progress by electricity, and galvanization of the spine ELECTRICITY. 385 lessens somewhat the severity of the neuralgic pains which belong to this malady. Recently it has been shown that persistent use of the faradic brush to the spine, body, and extremities, is in suitable cases remarkably effective. Of all the remedial means now employed, this is the most promising, for Strumpf, of Dusseldorf, who has revived this treatment, reports not only amelioration but apparent cures of this before intractable disease. Nothing is more certain in therapeutics than the relief to pain by galvanization of the affected nerve or nerves. In tic-douloureux de- cided relief to the pain is obtained by electrical applications to the fifth, and a permanent cure not unfrequently results in those cases belonging to the category of the essential neuralgias, so called. The best method of application is that advised by Onimus and Legros, which consists in placing the positive pole on the point of emergence of the affected nerve, and the negative over the superior ganglion of the cervical sympathetic. About ten elements of Siemens and Hal- ske is the proper strength, and five to eight minutes the proper time, for these applications. This method of treatment is, according to Frommhold, the most effective remedy for migraine or hemicrania. In cervico-brachial neuralgia, and in sciatica, excellent results are obtained by galvanization of the affected nerves. The positive pole should be placed over the point of emergence of the nerves from the cord, and the negative over the main divisions of the peripheral expan- sion. Both labile and stabile currents may be employed. A current from thirty elements will usually be required. The electrodes should be large sponges well moistened. In old cases of neuralgia, a needle such as is used for acupuncture, but insulated to near its point, may be introduced down to the neighborhood of the nerve-trunk and attached to the positive pole, while the negative sponge-electrode may be passed over the course of the nerve. This mode of galvanization is especially to be recommended in old cases of sciatica. A daily seance of from five to fifteen minutes is required usually in cases of neuralgia. The cure is much more difficult, and the applications must be continued over a much longer period of time, in those cases of neuralgia depend- ent on neuritis. Decided amelioration and even cure may be hoped for by sufficiently prolonged applications, when the nerves are so far altered that induced currents do not cause any muscular contractions. Some of the most satisfactory results have been obtained from galvan- ization of the uterus in uterine and ovarian nerve-pain. In certain kinds of muscular spasm the galvanic current has un- questioned utility. Cases of spasmodic wry-neclc (torticollis) of recent origin, due to " rheumatism," are quickly relieved by galvanization by stabile currents of the affected muscles, and faradization of the opposed muscles. Old cases of wry-neck and convulsive tic of the face, and writer's cramp, are not benefited by this treatment. Cases of chorea 25 386 EXCITO-MOTORS. have been cured by static electricity, but little benefit has been derived, according to the author's observation, from galvanism or faradism. Galvanism is sometimes of great service in epilepsy ', but no exact indications for its use can be laid down. Obviously it can only be ser- viceable in idiopathic epilepsy. The applications should include the brain (transverse current from mastoid process), the cervical sympa- thetic, and those nerve-trunks along which an aura is transmitted. The author has witnessed some remarkable results from the galvan- ization of the pneumogastric nerves, and as conspicuous failures from the same practice, in spasmodic asthma. Even in those cases not per- manently improved, great relief to the difficult breathing is experienced when the current is passing. The positive pole is placed over the pneu- mogastric, beneath the mastoid process, and the negative pole is applied to the epigastrium. Faradism is not serviceable in this disease. ^Exophthalmic goitre, a disease of the sympathetic system and manifested objectively by proptosis, goitre, and palpitation of the heart, is cured by galvanization of the cervical sympathetic and of the pneu- mogastric, and by applications to the eyes and thyroid gland, when it is merely functional in character. There can be no reasonable doubt of the influence of electricity over the nutritive functions. Beard and Rockwell employ the method termed by them " general electrization," which consists in faradic ap- plications to the surface of the body, "one pole, usually the negative, being placed at the feet or the coccyx, while the other is applied all over the surface of the body." They formulate their principles in these applications as follows : " Constitutional diseases are better treated by general, and local diseases by localized electrization." Ac- cording to Benedikt — and in this view electricians are generally in accord — the true method of using electricity consists in making appli- cations to the affected part or organs, and, to this rule may be added, to those parts or organs also in which symptoms are felt. General electrization is useful " in those diseases that are dependent on, or associated with, impairment of nutrition and general debility of the vital functions, such as nervous dyspepsia, neurasthenia, anwmia, chlorosis, hysteria, hypochondriasis, paralysis, and neuralgia of a con- stitutional origin, rheumatism and other toxic diseases, some forms of chorea, and oftentimes in functional disorders of the genital, digestive, and other special organs." In anrnmia and chlorosis the usual remedies for these states may be much assisted by central galvanization, and localized applications to the vegetative organs. Regurgitation of food, gastralgia, and feeble- ness of digestion, are often signally benefited by galvanization of the pneumogastrics, and by localized applications to the abdominal organs. Strong currents are needed when internal organs are to be affected by electrodes applied to the integument of the abdomen. A more effec- ELECTRICITY. 387 tive application in these cases consists in the use of an insulated rectal electrode, while a sponge electrode of large size, and well moistened, is passed over the various organs of the abdomen. The relief of con- stipation by this means has already been alluded to. Various diseases of the pelvic organs, both in the male and female, are successfully treated by electricity. Amenorrhea, when dependent on atony of the ovaries and uterus, is cured by static electricity, by faradism, or by an interrupted galvanic current. A shock from a Ley den- jar may be transmitted through the pelvis, or a strong faradic or galvanic current may be applied by means of one pole on the spine, the other on the hypogastric region. In the case of married women an insulated vaginal electrode may be introduced and placed in con- tact with the os uteri. This is a more effective way of making the applications than by the electrodes placed externally. In neuralgic dysmenorrhoea the galvanic current will afford relief in a large propor- tion of cases ; and, in congestive dysmenorrhoea, an inverse current will diminish the blood-supply, and thus lessen suffering. The treat- ment of these affections should be conducted during the interval. The chronic congestive enlargement of the uterus is sometimes remarkably benefited by a galvanic current of moderate intensity slowly inter- rupted, but it is doubtful if any case of chronic interstitial metritis is ever cured, or even ameliorated, by this means. Although the changes in the joints, induced by gout and rheu- matism, may not be cured by galvanization of the central nervous system, as claimed by Meyer, yet there is no doubt that myalgia, lum- bago, and other so-called rheumatic diseases of the muscular system, may be promptly relieved and cured by the constant current. The stiff- ness of the joints and the muscular soreness which remain after an at- tack of acute rheumatism are best relieved by passing a mild galvanic current through the affected parts. t Herpes, especially herpes zoster, and prurigo, when they are refer- able to an alteration of the cutaneous nerves, are curable by electricity. The author has seen excellent results in cases of shingles, from gal- vanization of the affected intercostal nerves — the positive pole being placed over the point of emergence of the nerves, and the negative brushed over the terminal filaments in the skin. Beard reports the cure of obstinate cases of chronic eczema by central galvanization, and his results have been confirmed by others. The author has seen a number of cases of acne get well under the influence of galvanization of the cervical sympathetic, and local galvanization of the skin of the face — the positive pole on the neck, the negative passed over the af- fected parts. It need hardly be stated that strong currents are not to be used when the poles are applied in these situations. Among the other skin-affections treated by galvanism with success are prurigo, psoriasis, and even scleroderma ; but, as Dr. Piffard, of New York, 388 EXCITO-MOTORS. has remarked, this method is " by no means uniformly successful." It is applicable to the treatment of the neuroses of the skin. Electrolysis. — When the electrical current is made to traverse insulated needles introduced into the tissues of the body, electrolytic effects are produced, decomposition of the tissues ensues, hydrogen and the alkalies appear at the negative pole, and acids and chlorine at the positive. Remak, in his various publications, much insisted on the catalytic action of the constant current. Effusions into and about inflamed parts, and into the substance of tumors, may be made to dis- appear by the external application of galvanism, through moistened sponge-electrodes. It is doubtful, however, whether neoplastic forma- tions can be thus made to undergo absorption. The disappearance of effusions induces such an appearance of shrinking of tumors and in- flammatory products, that actual absorption of the neoplastic material may be supposed to have occurred. Galvano-puncture is used to remove malignant and other new for- mations. The sanguine expectations once entertained that cancer can be thus removed, although justified by the results in a few apparently successful cases, have not been realized. Beard proposed and has executed a new method, entitled " working up the base," which con- sists in electrolytic decomposition of the subjacent parts of a can- cer. A number of needles, insulated to near their points, are intro- duced into the healthy tissues beneath the morbid growth, and a cur- rent from twenty to sixty elements is passed through them. Decom- position ensues, and there takes place a separation of the morbid mass. As the pain of this method is great, etherization should be resorted to. Aneurisms, so situated as to be beyond the reach of surgical inter- ference, have been treated by galvano-puncture, but the success, al- though brilliant in a few instances, has not been such as to justify very sanguine expectations of its future utility. Erectile tumors are curable by electrolysis. Goitre is sometimes made to disappear by the same means. The cysts connected with glandular tumors in the neck may be permanently occluded by galvano-puncture. The most useful applications of this method have been in hydrocele, which may be often cured in my experience by introducing two needle-electrodes, insulated to near their points, and passing a current from twenty to forty elements. Not less effective is the same method in the treat- ment of hydatid disease of the liver. One needle connected with the negative pole is introduced, and the sponge-electrode is placed at some indifferent point on the abdomen. Spasmodic and permanent stricture of the urethra are treated by electrolysis, an insulated sound with a metallic tip, connected with the negative pole, being passed into the stricture, and the positive pole placed at some indifferent point. The most successful results have ELECTRICITY. 389 been obtained by Mallez and Tripier, and Dr. Robert Newman, of New York ; but it is the author's observation, as also the expe- rience of Dr. Keyes, of New York, that this method has little real utility. Wounds and ulcers of an indolent character, and bed-sores, may be made to heal by attaching to them a galvanic couplet (zinc and silver), one of the elements remaining in contact with the sore, and the other on the skin in the neighborhood. They should be connected by a copper wire, and be confined to the parts by strips of adhesive plas- ter. This method has been especially serviceable in the treatment of bed-sores. Galvaxo-Cautery. — This method consists in cauterization by a platinum wire heated by the galvanic current. The battery used for this purpose furnishes a large quantity of electricity of low tension ; hence the elements are few in number but have extensive surface. When a quantity of electricity is made to traverse a platinum wire which offers great resistance, the wire is heated and may be melted. The platinum in the form of w T ire-loop, or dome cautery, or knife, heated by the electrical current, is the cauterizing agent. If the wire be not so highly heated as to cut through the tissues too rapidly, but little bleeding results, and a clean surface is left which promptly gran- ulates and heals. The instruments now employed for galvano-caustic work are chiefly the batteries of Piffard and Byrne, and the storage system of Trouve. Byrne's is said to be the most efficient of the original caustic batteries. The elements of this consist of zinc and platinum, and are so arranged as to offer the least resistance. The exciting fluid is bichromate solu- tion, and this is kept active by a bellows, or some other arrangement for agitating the fluid. The storage system is supplanting all other arrangements for the purposes of galvano-cautery. This consists of an element or combina- tion of elements which may be charged by another battery. The form of " storage-cell " or " accumulator " now chiefly used consists of plates of lead, immersed in dilute sulphuric acid. These are charged by some Daniell or Bunsen cells, communicating with them, and in action for several hours. Bubbles of hydrogen gas form on one lead plate, and of oxygen on the other ; whence they are said to be "polar- ized," and the current produced by the recombination of the gases is called a "current of polarization." By such an arrangement the quan- tity of electricity furnished by some Bunsen or other cells, acting for many hours or days, can be given out in a short time and in immense quantity. The accumulators of Faure, charged in Paris, have been transported across the ocean to give out their force in New York. Trouve has utilized this principle in constructing his " polyscope." A storage-cell of Plante is charged by the action of two Bunsen elements, 390 EXCITO-MOTORS. and subsequently the stored-up electricity can be employed in heating a platinum wire or knife for cautery purposes, or for illumination. When this system is fully developed, storage-cells, or accumulators, will be provided from some station and transported to any point de- sired, and the force given out as required. Furnished with suitable platinum loops, knives, and cautery, the operator can employ the ma- chines anywhere. Obviously, this method will be utilized on a large scale for various operative procedures — for the removal of the tongue, of polypi, of hemorrhoids, for opening the trachea, deep-seated ab- scesses, etc. A beautiful application of the galvano-cautery was made by Thomas, when he opened the sac of a tubal pregnancy by a gal- vanic knife. The evident advantages of this system are the little pain which attends the operation, and the absence of haemorrhage. It is necessary to accurately adjust the strength of current, so that the wire or knife will have the requisite temperature to cut the tissues sufficiently and yet not so rapidly as to prevent adequate closure of the vessels.

Static Electricity. — The modified Holtz or Toepler-Holtz elec- trical machine is now used to procure all of the nerve and muscular effects hitherto obtained by faradic electricity, and also therapeutical results of a very striking kind. It has long been known that chorea and other nervous affections may be readily cured by static electricity, but a remarkable extension has been given to the subject by late dis- coveries. Chorea is now treated by the " electric bath," sparks being drawn from the spine. If the Holtz machine is used, sparks can readily be drawn through the clothing, by presenting the brass knob along the spine. The results, which have been so long obtained at Guy's Hospital by this mode of electrical applications, are now generally conceded. It seems to be the most successful method of treating this disease. Neuralgia is now promptly relieved in most instances by in- sulating the patient and drawing sparks from along the trajectory of the nerve affected. The pains of progressive locomotor ataxia are much benefited in the same way, and it is said the disease itself is arrested. Amenorrhea, other conditions favorable, is quickly cured by sparks, or a shock sent through the pelvis. The general nutrition is greatly promoted by electrization by sparks. The Toepler-Holtz machine may, by connecting the interior of one condenser with the exterior of the other, be utilized to procure the muscle and nerve reactions of the faradic current. Trouve's Polyscope, referred to above, will probably be largely employed in the future, for the purposes of illumination. Suitable throat and other mirrors, platinum knives, and loops, are furnished with the instrument for illumination of the cavities, and for the va- rious caustic operations. It is very powerful, occupies but little space, NUX VOMICA. 391 and promises, when certain mechanical defects are overcome, to fulfill more perfectly than any other apparatus the requirements of a surgi- cal galvano-caustic and a medical illuminating apparatus.

Composition. — Nux-vomica contains two alkaloids and a peculiar acid. The alkaloids are strychnine and brucine, and the acid strychnic or igasuric acid. The proportion of strychnine ranges from one fourth to one half of one per cent, and of brucine from one eighth to one per cent. These wide differences are in great part due to the varying skill of the chemists who have made analyses. Besides these, another crys- 392 EXCITO-MOTORS. tallizable base has been discovered in the mother-liquor from which strychnine and brucine have been precipitated. This has been named igasurine. The alkaloids exist in nux-vomica in combination with igasuric acid. Strychnine is a white or grayish- white powder, of an intensely bitter taste, nearly insoluble in water, slightly soluble in cold alcohol, and readily soluble in boiling alcohol. When heated it melts, and by strong heat is wholly dissipated. It is but slightly or not at all red- dened by nitric acid. A small portion dissolved in official sulphuric acid yields, on the addition of a minute quantity of bichromate of potassium, a splendid violet color. Strychnince Sulphas. — Sulphate of strychnine. A white salt, in colorless, prismatic crystals, which are without odor, exceedingly bit- ter, soluble in ten parts of water, sparingly soluble in alcohol, and in- soluble in ether. They effloresce on exposure to the air, and melt when heated, losing nearly fourteen per cent of their weight of water of crystallization. By a strong heat they are wholly volatilized. Dose, gr. A-gr- if (U.S. P.) Antagonists and Incompatibles. — The paralyzers, such as woo- rara, conium, tobacco, opium, belladonna, and physostigma, antagonize the actions of strychnine in a part of the sphere of its influence. They do not antagonize its toxic action. Chloral, tobacco, bromide of potassium, ether, and chloroform (inhaled), are its true physiological antagonists. In cases of poisoning, tannin and the vegetables containing it should be freely administered, for the tannate of strychnine is very insoluble. Emetics, or the stomach-pump, must be used promptly. The tetanic spasms are best controlled by chloral and the inhalation of ether, or by tobacco, or by the bromide of potassium in very large doses ( 3 ij — | ss). The maintenance of artificial respiration has a decided effect in postponing in animals as in man the lethal action of strychnine. Strychnine should not be combined with bromides, chlorides, and iodides, in the same solution. Accidents have happened by taking the last portion, which will contain all of the strychnine, precipitated as hydrobromate, hydriodate, etc. Synergists. — Brucine, picrotoxine, thebaine, ergot, and, according to my own experimental investigations, belladonna, electricity, cold, etc., promote the activity of nux-vomica and its alkaloids. Physiological Effects. — The preparations of nux-vomica are ex- tremely and persistently bitter. Like all bitters, they promote the flow of the stomach and intestinal juices, increase the digestive power, and thus favorably affect the appetite. They also hasten the intestinal movements, and the stools voided are somewhat relaxed. The alkaloids of nux-vomica are very diffusible substances, and NUX VOMICA. 393 enter the blood very quickly. They lessen somewhat the oxidizing power of the blood, but this effect is quite insufficient to account for the physiological reactions produced in the nervous system. Small medicinal doses of nux-vomica and its alkaloid accomplish no more than other bitters, as respects the circulation. More or less plethora, slightly increased action of the heart, and, as a consequence of this condition of the vascular system, a greater energy in the performance of the various functions, result from their administration. When a lethal dose of nux-vomica, or of its alkaloid, has been taken, characteristic symptoms follow in a few minutes. The state of the stomach as to food, the presence of tannic acid in the food, and of fat, probably ; also the condition of the blood-vessels, influence the rate of absorption, and symptoms may begin in a few minutes or be delayed an hour or even longer. When a full medicinal dose has been taken, some slight shuddering, a sense of constriction of the fauces and jaws, sudden pains like electric shocks passing through the limbs, startings of some of the voluntary muscles, dilated pupils, " a meaningless smile," paleness of the face, followed by flushing and increased warmth of the surface and perspiration, are symptoms which may be produced without further development of a toxic action. If the dose be large enough to cause death, the above-described symptoms are quickly followed by tetanic convulsions, in which nearly all the voluntary muscles are engaged. When the paroxysm occurs, a shud- der passes through the whole frame ; the head and extremities jerk and twitch, and then suddenly a general tonic convulsion takes place — the limbs are extended, the hands clinched, the toes and feet incur- vated, the head bent backward, the body arched and rigid, the abdominal muscles hard and tense, the respiratory muscles fixed so that the body, curved in the form of a bow, rests on the occiput and heels. The countenance assumes a ghastly grin — the risus sardonicus ; the arrest of the respiratory movements suspends oxidation of the blood, and the skin becomes cyanosed ; strong erections of the penis occur, and frequently involuntary evacuations of semen, urine, and faeces take place. Rarely does death ensue in the first paroxysm ; the spasm relaxes, and nothing remains of the attack but the muscular soreness and fatigue, and the sense of impending dissolution. Ab- solute quiet retards the paroxysms. At first the senses are preternat- urally acute, and, as the reflex function is abnormally excitable, the slightest peripheral irritation suffices to bring on the spasms. Gener- ally patients experience comfort when the limbs are strongly held, or even rubbed, during the paroxysms ; but, in the interval, absolute quiet is most grateful. The mind remains unaffected until the close, or, at least, until carbonic-acid poisoning sets in. The paroxysms rapidly succeed each other, and increase in duration and severity, death occurring usually by fixation of the muscles of respiration, or 394 EXCITO-MOTORS. by exhaustion, and within two hours, as a rule, from the beginning of symptoms. The remarkable similarity in the symptomatology of traumatic tetanus and strychnine tetanus requires that the points of difference between them be clearly set forth. In strychnine tetanus the jaw- muscles are not first thrown into spasm, and are not always rigid dur- ing the paroxysm ; in traumatic tetanus, trismus is one of the first symptoms. In strychnine tetanus, after the convulsion, lasting from a half to one or two minutes, there is usually complete relaxation ; in traumatic tetanus rigidity of the affected muscles continues. A case of strychnine tetanus goes on rapidly increasing in severity, and lasts from a few minutes to two hours ; a case of traumatic tetanus proceeds more slowly, and lasts always a number of hours, and may extend over days and even weeks. And, lastly, in traumatic tetanus, the capital symptom of a wound or injury exists. No very characteristic post-mortem appearances result from strych- nine-poisoning. The muscles, at first relaxed, become rigid, the feet turned in, the fingers clinched, or the body may maintain the position of opisthotonos, in which it was at the moment of death. Conges- tion of the cerebral and spinal meninges is usually observed, and Schroeder Van der Kolk first ascertained that dilatation of the vessels and sanguineous extravasations are found in the gray matter of the cord (medulla oblongata), and this observation has since been repeat- edly confirmed. The smallest quantity of strychnine which has produced a fatal re- sult in an adult was a half -grain. Rarely can one twelfth of a grain be given without causing muscular twitchings, and one sixteenth of a grain has caused death in a child of between two and three years. The effects of strychnine are exerted on the spinal cord, on the seat of the motor functions. It does not affect the functions of the motor nerves directly — the irritability of the motor nerves is not de- stroyed by strychnine, it is exhausted by over-stimulation. The sen- sory nerves are either unaffected, or their irritability is exhausted. The reflex functions of the spinal cord are exalted. The afferent nerves, while preserving their irritability, communicate impressions to the reflex centers, motor impulses are quickly originated, and the mus- cles through the motor nerves are fixed in a state of tonic contraction. The over-stimulation of the cord and the motor nerves exhausts the irritability of the latter. The muscles preserve their contractility. The effects of strychnine are not limited to the nervous system of animal life : the organic nervous system participates in the perturba- tion. The dilatation of the pupil, the erection of the hair-follicles, the tinnitus, the increased heat in the limbs, and the perspiration which are produced when strychnine is injected subcutaneously, indicate an influence on the sympathetic system similar in kind to that exerted NUX VOMICA. 395 «. on the voluntary. Experimental investigations have confirmed these clinical observations. A very considerable rise in the arterial pressure, contraction of the vessels in the frog's web, and increased action of the heart, have been experimentally demonstrated to be caused by strychnine (Sigmund Mayer). Magendie, who made the first study of the actions of strychnine, found that, by previously destroying the spinal cord, no convulsions followed the administration of a poisonous dose. The precise agency of the cord is disputed, but it is in a high degree probable that the condition is one of exaggerated reflex excitability, so that the smallest possible peripheric irritation induces a response in the reflex motor center. When Setschenow's inhibiting center of reflex movements is withdrawn as in the decapitated frog, the spasms are induced as before. The passage over the face of the faintest current of air, even the men- tal conception of such an impression, will excite the spasms. Abso- lute repose, as by placing the poisoned frog under a bell-glass, the table firm so that no jar can reach the animal, and light excluded, has a decided effect in preventing attacks. If a poisoned human subject is similarly protected, the convulsions are diminished in violence. Again, if, when the convulsions are impending, the limbs are firmly grasped and held, the force of the spasm is lessened thereby. The medicines most effective in affording relief are those which lower the activity of the reflex function— notably chloral, bromide of potassium, etc. These facts indicate that an exaltation of the reflex function of the spinal cord is caused by strychnine. But this is probably not alone sufficient : irritation of the motor cells is also a factor (Spitzka). In opposition to the commonly accepted view, Falck maintains that strychnine acts primarily on the brain, or rather on the vaso-motor center of the brain, then on the inhibitory center for the heart, and the respiratory center, and lastly on the reflex apparatus of the cord. The spasms are the combined results of these actions. Bernard held that the sensibility of the sensory nerves is destroyed by strychnine, but after the motor functions have ceased. Martin- Magron, and subsequently Yulpian, ascertained that the sensibility persists after motility has ceased. This contradiction of supposed facts has been examined more recently by Busch, whose observations, if entitled to belief, support the statement of Bernard. Busch has found that the toe of the poisoned frog may be crushed, and the cen- tral portion of the divided sciatic may be burned, without inducing spasms or reflex movements, when the slightest jar of the animal will cause strong convulsions. Kolliker and Vulpian, with many others, hold that the excitability of the motor nerves is so far impaired by strychnine that irritation of the nerve-trunk produces very feeble or no muscular contractions. The American observers Klapp and Spitzka both maintain that the peripheral nerves are unaffected in strychnine- 396 EXCITO-MOTORS. poisoning. Martin -Magron et Buisson and Vulpian find that the action of strychnine is local on the nerves, and is therefore greatly influenced by the quantity of the poison reaching them. If the dose of strych- nine is small, the motor and sensory nerves remain unimpaired ; but if the dose be large, their irritability is destroyed. The influence of the quantity administered is consequently very great, and is exhibited in other respects. Thus, while a merely lethal dose causes strong con- vulsions, a very large toxic dose will kill at once without any reflex disturbances. It is impossible, then, to make the distinction between motor and sensory nerves as respects the action of strychnine: it either destroys or spares the excitability of both. While strychnine exalts the irritability of the reflex motor center, it stimulates the vaso-motor center or centers in the cord, with the re- sult of greatly increasing the blood-pressure. This rise in blood-press- ure is prevented by dividing the cord, according' to Mayer, Klapp, and others, but, according to Schlesinger, not. Now, as it has been found by Richter, who has studied the circulation in transparent parts, by Mayer, and by Spitzka, that the arterioles strongly contract under the influence of strychnine, the blood-pressure must rise from this cause ; hence, the observation of Schlesinger is probably correct, that the blood-pressure rises in strychnine-poisoning, notwithstanding di- vision of the cord. As has been tersely expressed by Spitzka, " its vaso-motor effect is to increase the blood-pressure and the rapidity of the blood-current by contracting the arterioles. This effect is inde- pendent of the central nervous system." The effects of strychnine on the heart differ in cold- and warm-blooded animals, according to most authorities, and decidedly, also, according to the size of the dose. On frogs, the diastolic pause is prolonged, and the force of the systole augmented, so that arrest of the heart's action may take place in te- tanic rigidity. These results, Spitzka holds, are due to an action on the cardiac ganglia and on the pneumogastric. The previous obser- vations of Heinemann, however, do not correspond, for he finds that these phenomena are produced after the vagi are divided. In warm- blooded animals the heart's action is accelerated, while the tension is raised. Klapp, however, finds that strychnine slows the pulse in the cat and rabbit, and that the retardation is due to an impression on the cardiac motor ganglia, and not to stimulation of the inhibition. He finds that the action is the same on both classes of animals. These contradictions are probably due to the difference in the dose employed. A large toxic dose of strychnine will paralyze, instead of stimulate, the vaso-motor center in the medulla, and thus prevent any rise of blood-pressure. A small, merely lethal dose will stimulate the cardiac ganglia, the pneumogastric, and the vaso-motor ganglia ; but a large toxic dose will slow the heart, paralyze the vagi and the accelerator apparatus, and depress the vaso-motor functions generally. In the NUX VOMICA. 397 course of annual experiments for class instruction, the author has con- stantly observed the difference in results due to the quantity adminis- tered. From clinical observation, in the absence of any experimental evi- dence, strychnine has been ascertained to have a stimulating effect on the respiration. If the dose is less than sufficient to tetanize, the func- tion of respiration is increased in energy and in depth. Hence, this agent antagonizes the respiratory poisons, as well as those morbid states which depress the respiratory function. On the blood, the experiments of Harley show, strychnine has some action. Agitation of blood with the air, in the presence of strychnine, is followed by a less production of carbonic acid than if strychnine be not present, but such experiments are entitled to small consideration. Strychnine, as Hippel and Cohn have shown, stimulates the retina and increases the sharpness of definition and the area of the visual field. These facts explain the curative effects of strychnine in certain dis- eases of the retina. Very peculiar phenomena have been observed by Spitzka as a re- sult of chronic poisoning — an entirely new subject. It appears to be exceedingly difficult to keep animals alive, but Spitzka succeeded in maintaining five frogs in tetanus for over forty days. Symptoms oc- cur under these circumstances quite distinct from those produced in acute poisoning by strychnine. Disease in the cord is set up, " partly as an insular sclerosis, partly as an hemorrhagic or non-haemorrhagic myelitis." These experiments demonstrate that, to maintain a con- stant effect by strychnine in the beginning, the dose must be increased, but later the quantity given may be decreased and administered at longer intervals. The importance of these observations from the ther- apeutical point of view is, indeed, great. The symptoms occurring from chronic poisoning are, as respects the spasms, a diminution of their energy, the development of an ataxic state, with tremors and pupillary myosis. These phenomena approach those produced by pi- crotoxin, and are intermediate between the effects of strychnine proper and of curara or methyl strychnium. Therapy. — The tincture of nux-vomica is one of the numerous remedies proposed for the vomiting of pregnancy. It is best adapted, according to the author's observation, to those women who have a sea- sick feeling and who do not vomit much. Half a drop to a drop, in cherry-laurel water, or in simple water, every hour or two, is a suitable dose. Like all other remedies, nux-vomica often fails in this malady. Owing partly to its intense bitterness, and partly to its in- fluence on the nervous system, the tincture of nux-vomica is an excel- lent stomachic tonic, adapted more especially to the treatment of those cases in which there is a neurotic element, as, for example, atonic dys- pepsia and gastralgia. From five to ten drops three times a day be- 398 EXCITO-MOTORS. fore meals is a suitable dose in these cases. In chronic gastric catarrh, whether occurring as an independent affection, or as an accompani- ment of other maladies, the tincture of nux-vomica is one of the most effective bitters. In the gastric catarrh and morning vomiting of drunkards, this remedy is next in value to arsenic. It may be given, advantageously, with mineral acids. The poor appetite, the feeble digestion, and the nervousness and trembling, which follow the sudden withdrawal of alcoholic stimulants, may be removed by frequent small doses of the tincture. To diminish the craving for stimulants when they are withdrawn, and to sustain the nervous system, the following combination is exceedingly effective : ^ Tinct. capsici, 3 vj ; tinct. nucis vom., 3 ij. M. Sig.: Twenty drops in water every four hours. Intestinal indigestion and flatulence are also removed by tincture of nux-vomica. In atonic diarrhoea, nux-vomica is a serviceable addition to other remedies, when a paretic condition of the muscular layer of the bowel may be presumed to exist. It is, however, more especially in consti- pation that nux-vomica is useful. It is indicated in those cases in which there are inaction of the muscular layer and, consequently, great fecal accumulations. It may be most advantageously given with pur- gatives in such cases : fy Tinct. aloes et niyrrhae, 3 vj ; tinct. nucis vomicae, 3 ij. M. Sig.: Fifteen to thirty drops two or three times a day. Nux-vomica has been signally useful in some forms of epidemic dysentery. It is indicated when there is depression of the vital forces, the intestines distended with gas, the stools like prune-juice. In some epidemics of cholera, strychnine, combined with mineral acids and opium, has appeared to be effective when the patient was about to pass into the state of collapse ; and it has also been used as a prophylactic during the preliminary diarrhoea : IJ Strychninae sulphat., gr. J ; acid, sulphuric, dil., § ss ; morphinae sulphat., gr. ij ; aquae camphorae, § iijss. M. Sig. : A teaspoon ful every hour or two, well diluted. This combi- nation is also effective in summer diarrhoea, when the evacuations are very watery, and in colliquative diarrhoea. When there is much pain, the quantity of morphine may be increased, or the first dose may be doubled. When the character of the case is such as to require con- tinued use of the prescription, of course, the quantum of strychnine must be lessened. Nux-vomica and its alkaloid strychnine are much used in combi- nation with restorative remedies, in cases of impoverished blood — in ancemia, chlorosis, hmmorrhagic diathesis, purpura, etc. In anaemia and chlorosis strychnine is used with reference to its power to stimu- late the blood-making organs, which functionate under some special influence proceeding from the nervous system. I£ Ferri sulph. exsic, 3ij ; quininae sulph., 3j ; strychninae sulph., gr. ss. M. Ft. pil. no. NUX VOMICA. 399 xx. Sig. : One pill three times a day. No prescription is more gen- erally useful in these states than the sirup or elixir of iron, quinine, and strychnine, a formula originally proposed by Aitken. In the treatment of amenorrhcea, the preparations of nux-vomica and strychnine frequently enter into the composition of prescriptions. In post-partum hcemorrhage, Fordyce Barker prescribes the tincture of nux-vomica (twenty drops), and fluid extract of ergot (thirty drops), " every half-hour until well assured that the uterus is well contracted." It is obvious that not more " than two or three doses " of such strength will be safe. The neuralgic form of dysmenorrhoea may be permanently removed by nux-vomica given during the interval. When impotence is due to mere relaxation and atony of the erectile apparatus, and is not dependent on organic defects, the preparations of nux-vomica are indicated and are useful. Incontinence of urine, when due to a paralytic state of the sphincter, may sometimes be cured by strychnine. Nocturnal incontinence, which is most successfully treated by belladonna, ergot, and iodide of iron, is sometimes not relieved by these agents, when strychnine may be tried. The author can not state with precision the cases in which it succeeds, but it has appeared to him most successful in those cases dependent on simple atony of the bladder, associated with general laxity of fiber. The most important uses of nux-vomica and its alkaloid are in the treatment of nervous affections, chiefly in paralysis. It may be used with advantage in hemiplegia, when sufficient time has elapsed to per- mit repair of the damage done by the extravasation. It is improper to use strychnine during the period of " early rigidity," and it is without avail in cases of " late rigidity " of the paralyzed members. It is most useful when the paralyzed members are completely relaxed. It is use- less when the paralysis has existed so long that the muscles have under- gone fatty degeneration, so that they no longer respond to a f aradic or slowly-interrupted galvanic current. Even if the necessary conditions as respects the state of the muscles are present, strychnine is inadmis- sible in cases of paralysis of cerebral origin when there are vertigo, headache, and tinnitus. In paraplegia of reflex origin, in rheumatismal paraplegia, in syphi- loma of the spinal meninges, paraplegia continuing after the removal of the deposits, strychnine is a most serviceable remedy. The best results are obtained from the use of strychnine in local paralysis, in lead-colic and constipation, and in drop-iorist, in mercu- rial and paludal palsies, in rheumatismal paralyses — for example, fa- cial paralysis, from exposure of the face to cold — torticollis, spinal curvature, from paresis of the muscles on one side, etc. In certain forms of spasms strychnine sometimes achieves most im- portant results. The evidence which has been accumulated as to the curative power of strychnine in tetanus would be very conclusive if 400 EXCITO-MOTORS. it were worthy of credence, which seems to the author doubtful. In this disease it should be given so as to substitute the strychnic for the traumatic tetanus, but the symptoms induced should not exceed those due to a full medicinal dose. Strychnine is most successful — as indeed are all the appropriate remedies — in the more chronic cases of tetanus, and in those of spontaneous rather than traumatic origin. Trousseau's experience is strongly in favor of the use of strychnine in the treatment of chorea. The method which he has pursued does not commend itself — it is heroic, and indeed unsafe. It consists in the use of such doses, beginning with one dose a day and increasing them, until stiffness of the muscles of the neck, spasmodic jerkings, and a " meaningless smile," indicate the beginning of strychnic poisoning. Strychnine is a very serviceable remedy in idiopathic or essential epilepsy. It is adapted to pale, anaemic young subjects who have the petit mal, as well as the grand mat, and whose attacks are nocturnal. It exerts no influence but an injurious one over symptomatic epilepsy — that dependent on " coarse organic lesions of the brain." It is said that the state of the retinal circulation furnishes an indication for strychnine or bromide of potassium, fullness of the retinal vessels be- ing an indication for the latter agent, and pallor and anaemia for the former. In that functional irritability of the nervous system manifested by restlessness and wandering neuralgic pains , strychnine affords relief. Spasmodic asthma of nervous subjects, when the paroxysms are due to an irritable state of the nervous system, are associated with vague neuralgic pains, and are determined by psychical influences, may be so far influenced by the persistent use of strychnine as to occur much less frequently. Amaurosis of a functional kind, from lead, tobacco, and alcohol, may be cured by strychnine. Paralysis of the ocular muscles (proso- palgia), of the muscle of accommodation, and paralysis of a single muscle, when these affections are due to an arrest of function of the nerve or nerves, and do not involve changes of structure, are curable by strychnine. Nagel, however, reports a cure of amaurosis in which there existed white atrophy of the optic disks ! Holtenhof points out the kind of amblyopia most benefited by this treatment. The cases without serious lesion, those dependent on anae- mia, on a reflex effect from some part of the trigeminus or sympa- thetic, or due to the abuse of tobacco and alcohol, are especially amenable to the strychnic treatment. " In central amblyopia," says Holtenhof, " without lesion of the macula and with decoloration of the temporal portion of the optic disk, I have obtained remarkable im- provement by the use of strychnine." Again, when there are lesions resulting from the deep-seated inflammation of the membranes, im- provement may be hoped for when the primary inflammation has NUX VOMICA. 401 ceased and the consecutive atrophy is stationary. In retinitis pigmen- tosa the results produced by strichnine are very striking. In five cases the diurnal dimness of vision and the nocturnal blindness were relieved considerably, in four cases there ensued an augmentation in the acuity of vision, and in two the visual field for white light was enlarged. Holtenhof finds strychnine inferior to electricity in the treatment of pa- ralysis of the ocular muscles. Strychnine has remarkable powers as a respiratory stimulant. Since the introduction of Aitken's formula for the phosphate of iron, qui- nine, and strychnine, the fact of its utility in chronic bronchitis, in- cipient phthisis, dilated bronchi, etc., has been distinctly recognized. The good effects of this combination are due chiefly to the strychnine. ATe possess no remedy more generally effective in the vomiting of phthisis than strychnine. This vomiting is reflex mainly, and occurs at the termination of a paroxysm of coughing, but there is also more or less stomachal indigestion. As the stomach is emptied, the vomiting interferes with nutrition. Strychnine has also, as Murrell has shown, some power to lessen the sweating of phthisis. This agent may, there- fore, be regarded as an important remedy in consumption. There are several modes of administration, but the best is by solution, the alka- loid dissolved in water with a mineral acid : I£ Strychninae, gr. j ; acid, muriatic, dil., § j. M. Sig. : Five to ten drops in water three times a day. Strychnine is one of the antidotes to chloral, as was first shown by Liebreich, but it is not the chief. It may be utilized cautiously as one of the means of counteracting the respiratory and cardiac depression, but it should not be depended on wholly. Nux-vomica has been used with success in the treatment of inter- mittents. At present it is rather employed as an adjuvant to quinine, than relied on as the sole curative agent. Hypodermatic Injection of Strychnine. — This important thera- peutical measure needs to be separately discussed. The solution which the author advises is as follows : I£ Strychninae sulphat., gr. j ; aquae destil. vel aquae lauro-cerasi, 3 j. M. Sig. : Ten minims contain one- forty-eighth of a grain. Some heat is usually necessary to procure a perfect solution. " The effects of strychnine," as has been well remarked (Echeverria), " are widely different when administered hypodermically or by the mouth. By the latter method the quantity may be repeated and in- creased, unsuccessfully, . . . and yet a smaller dose of the substance, exhibited hypodermically, be capable of regenerating at once the lost muscular power." The indications for the subcutaneous use of strychnine are precisely as those given above for its stomach administration : it is contraindi- cated in cases of hemiplegia when the injury to the brain has been 26 402 EXCITO-MOTORS. recent. It generally does no good, but harm, when the paralyzed muscles are rigid. It is most useful in old cases of hemiplegia, the subjects not being advanced in life, the paralysis incomplete, the muscles flaccid but not wasted, and having preserved their electro- contractility. Yery remarkable improvement not unfrequently fol- lows from this mode of treatment in suitable cases. The hypodermatic injection of strychnine sometimes is entirely successful in curing paraplegia, but the limits of its utility are well defined. It is not proper, and is in every way injurious, in acute cases involving structural alterations of the spinal cord. In doubtful cases, a strychnine injection may be used as a means of diagnosis be- tween structural and functional diseases of the cord : in the former, the symptoms are increased in definition ; in the latter, they are ame- liorated by the injection. This mode of using strychnine is curative in reflex paraplegia, in paraplegia due to anmmia of the cord, in hys- terical paraplegia, and in those cases of paresis of the muscles of the inferior extremities due to concussion of the cord, to rheumatism of the meninges, and to syphiloma, after the local morbid process has ceased. In infantile paralysis, the hypodermatic injection of strychnine is an important addition to other means of treatment. If the electro- contractility of the affected muscles is not lost, very beneficial results may be expected : the injection promotes the capillary circulation, and increases the growth and power of the muscles. £ In no form of paralysis is the use of strychnine more conspicuous for good than in diphtheritic paralysis. Few cases are not promptly benefited and most are quickly cured. The utility of the subcutaneous injection of strychnine has been most signally exhibited in the local paralyses ; e. g., facial paralysis, aphonia from paralysis of the vo- cal cords ; paralysis of the extensors by lead ; paralysis of the sphinc- ter vesical, of the sphincter ani, etc. The mode of practicing the injection is of considerable importance. The solution should be thrown into the substance of the paralyzed muscles. For example, in hemiplegia, the muscles in turn, of the paralyzed side, should be pierced by the needle, and the solution dis- charged into them. In drop-wrist the extensors should be grasped, made tense, and the needle of the syringe be thrust well into them. In paralysis of the sphincter ani and prolapse of the bowel, the muscle affected should be penetrated by the needle. When the affected mus- cles are beyond reach, the injection may be practiced at any indifferent point. Next to the treatment of paralyses, the most frequent application of strychnine by the hypodermatic method is in certain ocular mala- dies. In the normal condition, strychnine affects the visual functions. Hippel first studied these effects, afterward Sandi and Cohn, and sub- NUX VOMICA. 403 sequently, in France, Coumetou and Rouire. According to Counietou, strychnine augments the excitability of the retinal elements, increas- ing the sharpness of vision, central and peripheral, and also enlarging the visual field. He advises its use in amblyopia without lesions, de- pendent on functional disorder of the retina, and says it may also, if the lesions are not too far advanced, effect favorable changes in chronic diseases of the optic nerve and retina. Rouire also agrees with previous observers in stating that strychnine affects the optic nerve-fibers, increasing the normal acuity of vision and enlarging the visual field. He advocates its use in tabetic atrophy, and calls atten- tion to the fact that in certain atrophies good results are obtained only by a progressive increase in the amount administered. In these ocular maladies the solution may be injected in the temple, or in the nape of the neck, taking the usual precautions against accident. In infra- orbital neuralgia, good results have been obtained from the subcutaneous injection of strychnine. This practice may be very useful in neuralgia characterized by anaemia and depression. It may also be highly serviceable in epilepsy, the cases selected according to the rules already defined. Authorities referred to : Bernard, Cl.

J — gr. j. Tinctura Ignatice. — Tincture of ignatia (10 parts of ignatia to 100 parts of menstruum). Dose, tti, ij — nj, x. Composition. — Ignatia has the same composition as nux-vomica, but yields relatively larger proportions of the alkaloids strychnine and brucine. These principles exist in the bean in combination with iga- suric acid. Formerly, the bean of St. Ignatius was the principal source of commercial strychnine, but the abundance and low price of nux-vomica now compensate for the difference in strength. The preparations of ignatia are stronger than the corresponding ones of nux-vomica. Antagonists, Incompatibles, and Synergists are the same as for nux-vomica. Actions and Uses. — Ignatia, containing the same principles as nux-vomica, must have the same physiological actions and correspond- ing therapeutical properties. The tincture of ignatia, the most useful preparation, has a power- ful and persistent bitter taste, and, in common with bitters, has the effect known as stomachic tonic. It is a very effective stimulant of the gastric mucous membrane, promotes the flow of gastric juice, and hence increases the activity of the stomach digestion, and may there- fore be used with advantage in atonic dyspepsia, and in the nausea and vomiting of gastric and cerebral ansemia. It is also often highly serviceable in the gastralgia of nervous women having impoverished blood. The migraine or sick-headache of such subjects, also, may be relieved by ignatia. It may be very useful in the various disturbances belonging to chronic gastric catarrh, but it is contraindicated in all acute inflammatory affections. It is in these stomachal affections more especially that ignatia is preferred to nux-vomica by many prac- titioners. Ignatia affects the nervous system of animal life in the same way, but more energetically in the same dose, that nux-vomica does. It exalts in the same way the reflex function of the spinal cord, and simi- larly arrests respiration by a tetanic fixation of the respiratory mus- cles. It is, however, not used in affections of the nervous system, the alkaloid strychnine being now universally employed. Cocculus. — The fruit of Anamirta cocculus, or Cocculus Indicus. (Not official.) COCCULUS. 405 There are no official preparations except picrotoxin, the active prin- ciple. A saturated tincture may be used. Dose, % ij — tti xv. A fluid extract can be made, and is a useful form for administration. Dose, tti ij to Tii x, gradually increased. Composition. — The effects of cocculus are due chiefly to the presence in it of a peculiar neutral principle known as picrotoxin. This has been admitted to the Pharmacopoeia of 1880, and is therefore official. Picrotoxinum. — Picrotoxin. Is not an alkaloid, although allied to this group of substances. It does not combine with acids to form salts. It is neutral, crystallizable, forming needle-shaped, stellar, or foliaceous crystals. It is soluble in 150 parts of cold and 25 parts of warm water, and in alcohol, and dissolves freely in alkaline solutions. It is unaffected in solution by the metallic salts, tannin, etc., and is not precipitated by the tests for the alkaloids. It may be administered in pill-form, and can be combined with any of the usual so-called nervine tonics. Pi- crotoxin may be administered subcutaneously, in solution in water — one grain to f ss — the dose ranging from ■£$ of a grain to -fe of a grain. By the stomach it may be given in from -^ of a grain to -fa. Antagonists. — The carefully - conducted researches of Browne show that chloral is its physiological antagonist in rabbits and Guinea- pigs, and probably will prove to be of value in cases of poisoning in man. The anaesthetics, and the motor depressants in general, are an- tagonistic in respect to its power to produce spasm. Synergists. — All the remedies of this group, notably strychnine, brucine, and ergot, increase the effects of picrotoxin. Physiological Actions. — The taste of picrotoxin is bitter. It increases the flow of saliva. In what form soever administered, more or less nausea is produced, when the quantity given is sufficient to cause cerebral effects. It is not an irritant to the gastro-intestinal mucous membrane ; it increases secretion, and promotes peristalsis, but no hyperemia of the mucous membrane has been observed after death from a toxic dose. The secretions of the glandular appendages of the mucous membrane, probably also of the pancreas and liver, are decidedly increased, the stools becoming soft and more copious. Ad- ministered at any point, picrotoxin diffuses readily into the blood, but nothing is known at present of the changes which it induces, if any, in the composition of the blood. After death the right side of the heart is distended, and the left side incompletely emptied and flaccid. The action of the heart varies with the stage of the effects, and doubtless also more or less according to the size of the dose. At first the cardiac movements are slowed, the arterial tension somewhat elevated ; during the convulsions the action grows rapid, but, succeeding the convulsions, and during the stage of coma, the pulse becomes slow again. According to Planat, by small doses, the cardiac pulsations are slowed before the convulsions come on : then the muscular excitement 406 EXCITO-MOTORS. induces rapid action, to be succeeded again by the retarding effects of the remedy, increased by the coma. Roeber also finds that the cardiac contractions are retarded, and the walls of the heart dilated and flac- cid. The respiration is also accelerated, and there occurs strong in- spiratory dilatation, because of spasm of the glottis — effects which are due to stimulation of the pulmonary portion of the vagus, and which cease on division of this nerve (Roeber). When the convulsions cease, the respiration becomes slower and more shallow. No engorgement of the lungs is found after death (Browne). The pupils are not specifically affected. During the convulsions they dilate somewhat, when the tonic spasms come on, and contract again during the clonic spasms. The fundus of the eye, examined by the ophthalmoscope, exhibits considerable hyperemia. The cerebral effects of picrotoxin are variously interpreted. Drow- siness, stupor, some muscular trembling, are observed in cold- and warm-blooded animals, and have also been experienced in man. A heavy, stupid intoxication, with vertigo, inco-ordination, and dimin- ished sensibility, followed by after-headache, depression, and nausea, are symptoms ascribed to the action of cocculus Indicus in beer so- phisticated by this drug. Restlessness, unsteady gait, and weakness of the hind extremities, also precede the convulsions in animals. Twitch- ing of the ears, shaking of the head, and spasms in the eyelids, eye- brows, lips, and fore-paws, now come on. Then follows a distinct tonic convulsive stage, with opisthotonos, or emprosthotonos, tetanic fixation of the muscles of respiration, cyanosis, and stertor. This tetanic stage is succeeded by the general clonic convulsions, and the seizure is terminated by a temporary paralysis and coma. In the order and succession and character of phenomena, a remarkable similarity in the actions of picrotoxin to the epileptic paroxysm must be discerned. By Roeber the convulsions are referred to the effects of the poison on the medulla. He finds that, after destruction of the brain, the symp- toms are the same as before ; after destruction of the optic lobes, the convulsions are less violent ; but when the medulla is removed the con- vulsions do not occur, and a large dose causes coma only. These facts indicate that picrotoxin acts on the spasm and vagus centers in the medulla, and on Setschenow's inhibitory center. Planat, Chirone, and Testa, also hold that this agent acts on the cerebellum, medulla, and spinal cord, and leaves the brain exempt. Against these opinions we have the carefully-considered but still hypothetical view of Browne, who finds in Ferrier's cortical centers the real seat of the action of picrotoxin. That the center, and not the periphery, is the place where the action of the poison is expended, seems proved by the studies of Roeber, who finds that the electrical reactions of nerve and muscle remain unaltered. The action of the heart is arrested in the diastole, and, while the COCCULUS. 407 cavities are full, the capillaries at the periphery are empty. The vas- cular lesions, post mortem, are similar to those of epilepsy. That some of the poison is yet in the blood, is proved by the fact that flies eating it are poisoned. Elimination probably takes place by the various chan- nels of excretion, but chiefly by the kidneys. The skin is powerfully acted on, and hence picrotoxin ranks among the most active diapho- retics. The urinary excretion is also increased, but more exact obser- vations are needed on these points. Therapy. — Picrotoxin will, probably, be found very useful in cases of torpor of the intestines, dependent on deficient secretion and paresis of the muscular layer. In the night-sweats of consumption it has been used with great success by Murrell, who had but one failure in twenty cases. He finds that it is best to give the necessary dose at night — from y-^ grain to g^. The effect lasts about ten days, when the sweating begins again, and the remedy must be repeated. Picro- toxin has been used with success in the treatment of epilepsy by Pla- nat, Dujardin-Beaumetz, Hurd, and by Hammond. It is more espe- cially adapted to the weak and anaemic type. It has been also used with success in chorea, and with promising results in paralysis agitans. In a case of glosso-labio-laryngeal paralysis Gubler obtained a notable amelioration. Further experiences with these diseases are much need- ed. It is probable that this remedy may be applied with advantage to the treatment of other paralyses. According to Tschudi, it has been given in paralysis of the sphincters with good results. The tremors of chronic alcoholism have, it is said, been removed by it. One of the forms of sick-headache — that occurring at or about the menstrual period — is sometimes greatly relieved by its timely exhibi- tion. An ointment of picrotoxin — ten grains to an ounce of simple ointment — has been applied with success to the treatment of para- sitic skin-affections. Care is necessary, and abraded surfaces must be avoided. A saturated tincture of cocculus Indicus might be employed in place of picrotoxin. Planat recommends a tincture composed of one part of the berries to four parts of alcohol, and of this one drop is the ini- tial dose, morning and evening, increased daily by the addition of two drops, up to sixty or seventy drops for an adult, daily. In the diseases for which it is prescribed, it is necessary, to secure curative effects, that the physiological action be produced. Planat has used this tincture successfully in chorea, epilepsy, eclampsia (infantile), and in painful contractures of the extremities. Gubler advises the dose of a mille- gramme of picrotoxin for subcutaneous use. He has observed that indurated spots result from the injections, but they slowly disappear.

Ergotin. — This preparation must not be confounded with a con- stituent of ergot, supposed to be an active principle. The ergotin of the shops gets its name from "Bonjean's ergotin." It varies very- much in strength, owing to faulty modes of preparing it, and is not unfrequently inert. As prepared by Squibb it is entirely soluble in water, and represents the powers of the drug. Ergotin (the aque- ous extract) is the most eligible preparation for hypodermatic injec- tion. From one to five grains may be injected at one time. In pre- paring it for this purpose, the quantity to be injected should be rubbed up with fresh distilled or rain water, and then passed through the filter. It is always better to prepare it whenever required. If it is necessary to preserve the solution, the addition of a little carbolic acid — one grain to four ounces — will usually suffice. The addition of glycerin is not necessary, unless added as a preservative fluid ; and is objectionable, because it greatly increases the pain which attends the subcutaneous injection. Composition. — Some confusion yet exists in regard to the con- stituents of ergot, notwithstanding recent advances in our knowledge. An unfortunate nomenclature is in part responsible for the confusion ; but the complexity of the subject and the conflicting views of chemists are the chief causes of the present condition of the pharmaceutical knowledge of ergot. Ergot contains about thirty per cent of a saponifiable, non-drying oil, with which is associated a small quantity of resin and cholesterin. When extract of ergot is treated with an alkali, a peculiar fishy odor is developed, due to methylamine, according to some authorities, and trimethylamine according to others. Ergot also contains lactic and phosphoric acids and phosphates. The two principles, ecbolina and ergotina, separated by Wenzell in 1864, are not true alkaloids of ergot, and are said by Dragendorff to be identical. In 1830 a supposed al- ERGOT. 409 kaloid was obtained by Wiggers, which he named ergotin, but this is not the true active principle. Unfortunately, an aqueous extract, pre- pared by Bon jean, was also named ergotin. Kohler has examined the ergotin of Wiggers and that of Bonjean, and finds that they are mixtures : the former containing the ingredients of ergot not soluble in water ; the latter, those that are soluble in water. According to Kohler, neither of these so-called ergotins represents the properties of ergot. More recently Dragendorff and Podwissotzky have gone over the chemistry of ergot anew, with different results. They have in- troduced new terms also, which add to the complications. The most important principles obtained by them are sclerotic or sclerotinic acid, and scleromucin, the former existing in good ergot in tbe proportion of about four per cent, and the latter, two to three per cent. They have also separated other principles and secondary products, named re- spectively sclererythin, scleroidin, scleroxanthin, and sclerocrystallin. Another alkaloid has lately been discovered by Tanret, to which he has given the name ergotinine. This substance seems to be the nearest approximation to a genuine alkaloid of any hitherto proposed. It is a white, crystallizable solid, insoluble in water, and soluble in ether and chloroform. It is alkaline in reaction and has strong basic proper- ties, and combines with acids to form salts. It is an unstable sub- stance, and in the air soon decomposes. Antagonists and Incompatibles. — The caustic alkalies and the metallic salts are chemically incompatible. Aconite, veratrum viride, tobacco, lobelia, and amyl nitrite (Shafer), antagonize the action of er- got on the circulation. Synergists. — Electricity, cold, digitalis, belladonna, are synergistic as regards the vascular system. Savin, gossypium, rue, borax, increase its parturient action. Physiological Effects. — In small medicinal doses ergot does not produce sensible physiological effects. In large doses it causes symp- toms referable to the gastro-intestinal canal, and to the cerebro-spinal axis. It is bitter to the taste, and excites more or less heat and dry- ness of the throat, followed by thirst, stomach-pain, vomiting, intesti- nal pain, and occasionally purging. These gastro-intestinal symptoms are unquestionably due to the local irritant action of the drug ; for, after death, in a few fatal cases which have resulted from its adminis- tration, there have been found patches of inflammatory redness in the stomach and intestines. The active constituents of ergot diffuse into the blood. What changes, if any, are caused in the composition of the blood, are at present quite unknown. Very characteristic effects are, however, pro- duced in the circulatory system : the action of the heart becomes slower, and an enormous rise takes place in the blood-pressure. This influence on the circulatory system modern research has shown to be 410 EXCITO-MOTORS. due to the action of ergot on the vaso-motor nervous system ; it increases the action of this system, and causes a contraction of the arterioles. The dilatation of the pupil which follows is another evidence of this action. Pain in the head (usually frontal), dimness of vision, giddiness, and stupor, are also produced by it. The action of ergot on unstriped muscular fiber is further shown in the contractions of the parturient womb, the arrest of haemorrhage, and the difficulty of mic- turition, which follows its medicinal administration. The power of ergot to contract the arterioles has been repeatedly demonstrated in the web of the frog's foot. The phenomena above described, due to the administration of large medicinal or toxic doses, are known as acute ergotism. The peculiar morbid effects of ergot, when used for a long period of time as food (diseased grain), are known as chronic ergotism, which exists in two forms, the convulsive and gangrenous. Generally the convulsive form begins by vertigo, disorders of vision, tinnitus aurium, numbness of the fingers and toes, and afterward of the integuments of the body. These symptoms are followed by tetanoid contractions of the fingers, of the forearms on the arms, and of the arms against the chest ; of the toes on the palmar surface of the foot, of the leg on the thigh. The thoracic, abdominal, and diaphragm muscles are also tetanically contracted, and respiration becomes painful and difficult, and attacks occur similar to asthma. The intestinal muscles become affected by cramp, doubtless tetanoid in character, colics ensue, and diarrhoea ; the uterus in pregnant females takes on action, and abortion may result. The pulse is small, action of heart slow, and the surface cold. The appetite is generally ravenous. The tetanic spasms, at first separated by distinct intervals, become continuous, and opisthotonos or emprosthotonos is produced. Anaes- thesia (complete) of the surface succeeds to the tetanoid attacks, and gangrene of limited spots may occur. The organs of sense lose their sensibility and taste, hearing and smell are abolished. The pupils are dilated, sometimes unequal, and various disturbances of vision ensue. Epileptiform convulsions may occur in addition to the tetanoid spasms, delirium sets in, and complete insensibility at last supervenes. As has been shown by Lasegue and Tardieu, the gangrenous and convulsive forms of chronic ergotism are not separated by any well- marked pathological differences. The gangrenous form begins by tingling, numbness, formication, an insupportable sense of fatigue in the members, an earthy hue of the skin, coldness of the surface ; nausea, vomiting, and diarrhoea, with intestinal cramps, then occur ; muscular contractions take place ; an eruption of vesicles filled with a dark ichorous fluid appears on one or more extremities, and gan- grene, dry or moist, quickly destroys the toes, the legs, the nose, or other parts. ERGOT. 41 X The phenomena of chronic ergotism are evidently due to two causes — to the dyscrasia which exists in the subjects of this malady, owing to insufficient food and bad hygienic surroundings, and to the action of the ergot of the diseased grain, in diminishing the blood-supply to the cerebro-spinal axis, to the vegetative organs, and to the skin and muscular system. To this general sketch of the actions of ergot, it may be well to add some particulars of its most important physiological properties, and some observations on the actions of the recently discovered active principles. The most conspicuous effect of ergot, and that on which depends its therapeutical applications, is the influence which it exerts over the vascular apparatus. It is an undoubted fact, in respect to which all the investigators agree, that ergot diminishes the number and alters the character of the cardiac pulsations. The frog's heart may be arrested in the diastole by the intravenous injection of a full dose. By Rossbach and Wernich it was observed that a vermicular or peristaltic motion was given to the heart of frogs. The arrest of the heart's action is attributed by Eberty to stimulation of the vagus and a consequent increase of the inhibition. By Rossbach it is referred to an action on the cardiac muscle. It is in a high degree probable, however, that the slowing and depression of the cardiac functions is due to the action of ergot on the cardiac ganglia. To this may be opposed the observation of Willebrand, that the normal or hyperto- phied heart so contracts under the action of ergot that the difference in size is appreciable by percussion ! There is no dispute in regard to the contraction of the arteries induced by ergot. It has been observed and measured by Wernich, Briesemann, and Holmes. The notion that ergot causes contraction of the arteries by stimulating the vaso-motor system and its muscular apparatus has long been entertained. An enormous rise in the blood-pressure has been stated to occur by Eberty, Kohler, and H. C. Wood, and their opinion was based on kymographic observations. Holmes, Hermann, and Wernich, on the other hand, maintain that the blood-pressure is actually reduced. Wernich shows that the veins are dilated, and that a great accumulation of blood takes place in them, while, at the same time, the arteries contract, not re- ceiving from the slowly acting heart sufficient blood. The contrac- tion of the arteries is not, therefore, an active contraction, as has been supposed, but a collapse, the result of deficient supply of blood, which has accumulated in the dilated veins. By the theory of vaso-motor stimulation, it was easy to explain the action of ergot on the muscular fiber of the uterus and intestinal canal. If, however, the blood-press- ure falls after the administration of considerable doses, as Handelin, Brown-Sequard, and others affirm, and the arterial contraction is not active, how explain the uterine and intestinal action of ergot? This result is due to arterial ansemia (Wernich, Schlesinger, Mayer, 412 EXCITO-MOTORS. etc.). It is now clearly established that active movements occur in the muscular fiber of the intestinal canal and uterus by inducing an arterial anaemia. According to this view, then, the active peristalsis and the uterine contractions which follow the exhibition of ergot are the result, not of a direct stimulation of the sympathetic system, but of the diminished cardiac energy, dilatation of the veins, and arterial anaemia. The action of ergot is not limited to the vascular apparatus. The arterial anaemia which it induces may serve to explain the cerebral effects which follow its free administration in man, but, besides these, the functions of the spinal cord and peripheral nerves undergo changes. In frogs ergot induces paralysis, beginning in the hind extremities, and thence involving all parts, the circulation and respiration being the last to yield. In warm-blooded animals the same effects are pro- duced, and, if the action continues, finally the cardiac and respiratory centers are paralyzed. By Zweifel these central effects are held to be the principal, and all others merely secondary. On the other hand, the depression in the motor and reflex functions of the cord may be explained by the arterial anaemia, which is an undisputed effect of ergot, how much soever the mechanism of its production may be dis- puted. Indeed, it must be admitted that the actions of ergot are still subjudice. The numerous and often diverse views which have been expressed may be in part explained by the character of the prepara- tions. There can be no doubt that the active constituents are un- stable, and hence the pharmaceutical products vary, not only in the degree, but decidedly also in the character, of the actions. In Koh- ler's investigation, in which he compared the ergotin of Wiggers and Bonjean, there were very wide differences between them. The ergotin of Bonjean — an aqueous extract — excites the vaso-motor center in the medulla and the cardiac inhibitory center, and very large doses para- lyze the heart, the muscular tissue losing its excitability to galvanism. Wiggers's ergotin has no effect on the vascular apparatus. In these ex- periments of Kohler, with which Eberty was associated, the power of ergot to increase the blood-pressure is an important point. The atten- tive reader will observe that in these experiments the heart was para- lyzed, and the irritability of its muscular tissue destroyed. Wiggers's ergotin causes cramps of the intestines, and violent inflammation of the gastro-intestinal mucous membrane, effects which never result from Bon jean's. Both kinds of ergotin lower the temperature, and both retard the respiration. Bonjean's ergotin diminishes the irri- tability of the peripheral motor nerves, and Wiggers's increases it. Both lessen the irritability of the sensory nerves. Kohler concludes that, when it is desired to slow the heart, contract the vessels, dimin- ish reflex actions, and lessen temperature, the ergotin of Bonjean should be used. ERGOT. 413 The physiological action of sclerotinic acid has been carefully studied by Nikitin in Rossbach's laboratory. He starts out by affirming the identity of action between this principle and ergot. In frogs the reflex excitability of the spinal cord is reduced, then destroyed, but in warm-blooded animals it is reduced only. It does not affect the irritability of the motor nerves, nor the contractility of the muscles, but when brought in contact with sensory nerves, paralyzes them. Sclerotinic acid depresses the action of the heart in frogs, but not in mammals. In toxic doses it lowers the blood-pressure and reduces the temperature. The respiration is slowed, and, when toxic doses are given, the movements of respiration cease before the heart stops. The peristaltic movements are increased in warm-blooded animals, and the uterus, whether gravid or not, is excited to action. Death is due to paralysis of respiration. Sclerotinic acid has been freely prescribed by Yon Hoist, who finds it possessed of a high degree of activity, but other clinicians have been less successful — thus Robert, of Halle, finds it can not be substi- tuted for ergot. In my own experiments, I have found it produce effects, but not those of ergot proper. Sclerotinic acid is separated by alcohol, but Handelin, who had investigated this subject under the superior direction of Schmiedeberg, finds that ergot loses none of its activity by being extracted with alcohol. Handelin's experiments, made with an aqueous extract, present some points of interest. He found that small doses cause anaesthesia and impair the power of co- ordination, and large doses paralyze reflex and voluntary motions. As the peripheral nerves are unaffected, the paralysis is centric. Small doses lower the blood-pressure temporarily, and large doses perma- nently. The pulse is at first quickened, and then declines, becoming more and more slow until the heart is arrested. The first trials with Tanret's crystallized ergotinine were made by Dr. Mole, who found it as effective in uterine haemorrhage as ergot. The amount that he administered did not exceed four milligrammes in twenty-four hours. Galippe and Budin have also experimented with ergotiniue on frogs, cats, and dogs, and produced many of the effects ascribed to ergot, namely, slowing of the pulse, reduction of tempera- ture, paralysis, and convulsions. Peton, another investigator, has also experimented with ergotinine, the results of the action being contrac- tion of the arteries, restlessness, trembliug, diarrhoea, etc. An examination of the results obtained from the experimental and clinical trials with the so-called principles and alkaloids of ergot dem- onstrates that in no single one are contained all the powers and prop- erties of the drug. It is also evident that ergot, and those principles possessing its powers most nearly, depress the heart, and lower rather than elevate the tension of the arteries. The contraction of the ar- teries is not, therefore, an active contraction ; and, as the blood accu- 414 EXCITO-MOTORS. mulates in the veins, there is an anaemia of the cerebro-spinal axis and of the organic muscular fiber. To this condition of things may be referred the phenomena resulting from the exhibition of ergot. Therapy. — The only diseases of the intestinal canal to which ergot is applied are chronic diarrhoea and dysentery. It is best adapted to those cases in which the chronic succeeds to the acute form, and is not so serviceable in the chronic diarrhoea of warm climates, which has de- veloped slowly, without preliminary acute symptoms. $ Ext. ergotae fluidi, f iijss; tinct. opii deodor., \ ss. M. Sig.: A teaspoonful three times a day. ^ Ergotinae (aq. ex.), 3j ; ext. nucis vomicae, gr. v ; ext. opii, gr. v. M. Ft. pil. no. xx. Sig. : One every four or six hours. This last prescription is highly useful in persistent chronic diarrhoea. Dr. L. G. Andrew has treated acute dysentery successfully with the fluid extract of ergot. Dr. W. C. Dabney, of Virginia, urges the local application of fluid extract of ergot in affections of the mucous membrane characterized by enlarged vessels, as, conjunctivitis, cervi- citis, pharyngitis, etc., and by Dr. Eldridge it has been applied to the treatment of gonorrhoea, acne rosacea, etc. The theory of its action in these maladies is the artificial anaemia which it induces in the arterial vessels. Inflammation can not go on, because the blood-supply is in- adequate. In the local application the fluid extract of ergot is used. In most cases this may be applied directly to the membrane undiluted. The aqueous extract, or ergotin, may be utilized for these purposes also ; made into a paste more or less thick according to the character of the surface, it may be plastered on the affected part. Ergot in the form of the fluid extract, with or without nux-vomica, will often arrest the bleeding of haemorrhoids, and cause such a con- traction of the vessels in recent cases as that the symptoms may en- tirely disappear. This treatment is especially serviceable in the haemor- rhoids which succeed to delivery. Relaxation of the sphincter ani and prolapsus of the rectum may be ameliorated and, when recent, cured by the same means. Ergot is a useful remedy in cases of enlarged heart (dilated cavities) without valvular lesion. It may be given with digitalis : I£ Ext. ergotae fluidi, f iijss ; tinct. digitalis, f ss. M. Sig. : A teaspoonful three times a day. There is now no longer any doubt as to the value of ergot in aneurisms, and especially in internal aneurisms beyond the reach of surgical treatment. In these cases the methodus medendi is as follows : ergot slows the action of the heart, and causes such a de- gree of contraction of the arterioles as to produce a great increase of the blood-pressure, whence it follows that the coagulation of the blood in the aneurismal sac is greatly promoted. It is quite conceivable that, as respects small aneurisms of the peripheral main arterial trunks, ergot may effect a cure in the mode suggested by Langenbeck, viz., ERGOT. 415 by direct contraction, under the influence of the ergot, of the unstriped muscular fibers in the affected portion of the vessel. "With the use of ergot should be enjoined rest in the recumbent posture, and other measures to favor hyperinosis and the coagulation of the blood in the aneurismal sac. The recent, more accurate notions, regarding the physiological ac- tion of ergot, have led to its employment in various forms of hemor- rhage. With suitable means for improving the quality of the blood, ergot is very serviceable in the hemorrhagic diathesis ; but it is not to be relied on alone. The special indication for its use in haemorrhage is a want of tonicity of the vessels. It is used in epistaxis, hmmopAysis, renal, intestinal, and uterine hemorrhage. Large doses of a suitable preparation are necessary ; for, if the drug be inert, nothing but dis- appointment will be experienced from its use, and small doses do not produce sufficient effect. From half a drachm to a drachm of the pow- dered ergot, or one to two drachms of the fluid extract, given every half-hour or hour, will be necessary in urgent cases. As powdered er- got rapidly loses its activity by keeping, the fluid extract should be used, and only that prescribed which has been carefully made from the fresh drug. Attention to these precautions will insure more uniform results in hemorrhage than have hitherto been obtained. In hemop- tysis the fluid extract of ergot may be given with other appropriate remedies ; $ Ext. ergotae fluidi, § iij ; ext. ipecac, fluidi, tinct. opii deodor., aa 3 ss. M. Sig. : A teaspoonful every half -hour or hour. When the sputa are heavily charged with blood, and there is no de- fined haemorrhage, the following may be used : ^ Ergotinae (aq. ex.), 3] ; pulv. ipecac, gr. x ; acid, gallic, 3 j. M. Ft. pil. no. xx. Sig.: One every hour or two. In renal hemorrhage, the following is a use- ful formula and generally very effective : I£ Ext. ergotae fluidi, tinct. krameriae, aa § ij. M. Sig.: A teaspoonful every hour or two. Or, ergotine may be prescribed with gallic acid, as in the prescription above given. The indication for the use of ergot in menorrhagia is the existence of the large, spongy uterus — the condition of things which depends on subinvolution of the icomb. Menorrhagia, when caused by ovarian excitement, is usually more promptly relieved by bromide of potas- sium, and metrorrhagia, produced by fibroids or fungous granulations, is, in the author's experience, much more decidedly held in check by diluted sulphuric acid than by ergot. When there is reason to believe that vertigo, epistaxis, headache, and tinnitus aurium, are due to miliary aneurisms of the intra-cranial arterioles, most favorable results can be produced by the use of ergot. Also, when there is a sluggish and partially obstructed state of the intra-cranial veins, usually due to chronic arteritis, and accompanied by hebetude of mind, giddiness, epistaxis, etc, these symptoms are 416 EXCITO-MOTORS. made to disappear, and the mental condition is much improved by ergot. Dr. Crichton Browne, a physician of large experience in these dis- orders, finds ergot a very useful remedy in certain forms of mental disease, for example, " in recurrent mania, chronic mania with lucid intervals, and in epileptic mania." In these mental disorders he as- sumes the existence of cerebral hyperemia, and he deduces the cura- tive value of ergot from its power to cause contraction of the vessels. Migraine, when the attacks are accompanied by suffusion of the face, injected conjunctivae, and a full pulse — the congestive form — is cured by ergot, and Dr. Kitchen indeed extends its use to almost all kinds of headache. In epidemic cerebrospinal meningitis, ergot is one of the remedies from which the best results are to be expected. In congestion of the spinal meninges and the cord, and in acute myelitis, this remedy has probably been more uniformly successful than any other, but it must be given in large doses. Excellent results have been obtained from the use of ergot in acute inflammation of the conjunctiva, in blepharitis, and in the phlyctenu- lar ophthalmia of children. The long-continued use of ergotin has achieved remarkable results in chronic metritis. Uterine fibroids and polypi of the uterus are greatly benefited in two modes by ergot : uterine action is set up, by which the growth is either compressed or extruded, and the nutrient vessels are so diminished in caliber that atrophy of the morbid growth occurs. The numerous reported instances of success by this treatment, and the author's personal experience of its utility, justify him in urging a trial of this remedy in uterine fibroids and polypi. In congestive dysmenorrhea, much good may be expected from the use of ergot when the menstrual molimen begins. $ Ext. ergotse fluidi, 3 vij ; tinct. gelsemii, 3 j ; tinct. aconiti rad., gtt. xvj. M. Sig. : A teaspoonful every two, three, or four hours. Amenorrhoea, when dependent on plethora, has been cured by ergot. When incontinence of urine, nocturnal or diurnal, is caused by a paretic or paralytic state of the sphincter vesicce, relief may be confi- dently expected from the use of ergot. The fact that one of the ill results of the administration of ergot in large doses is an inability to void the urine, is an interesting explanation of the methodus medendi of ergot in these cases. Ergot is one of the most satisfactory remedies in the treatment of spermatorrhoea. It is not useful when the losses are due simply to plethora. Its curative value is especially exhibited in those cases in which the erections are feeble and infrequent, the intromittent power wanting, and the testes relaxed and deficient in secretory activity. Paralysis of the bladder, the result of over-distention, and occasion- ERGOT. 417 ally when due to cerebral or spinal lesion, is greatly benefited or cured by ergot. Ergot was first employed by Da Costa in the treatment of diabetes insipidus, and a number of cases have been cured by Murrell, Saun- ders, and others. The remedy must be perseveringly used, and in full doses, up to the stomach capacity or evidence of physiological action. Heitzmann has found ergot extremely useful in acne rosacea, and other forms of acne. He uses Squibb's fluid extract of ergot mixed with glycerin and water, giving 3 ss internally, daily. Ergot in Obstetric Practice. — It is no longer a matter of doubt that ergot promotes uterine contractions ; that it originates them with- out previous effort of the womb, is questionable. The contractions due to ergot differ from the spontaneous, natural contractions, in being less rhythmical and more tetanic. When large doses of ergot are used, a continuous expulsive effort may be produced. Ergot is indicated in labor when there is uterine inertia, the first stage being completed, and no obstacle existing at the outlet. If given before dilatation is completed, the perinaeum rigid, and the ostium vaginoe not relaxed, dis- astrous consequences may ensue, both to mother and child. On the part of the mother, the violent and continuous pains — the resistance in front remaining — may cause a rupture of the womb, or the resistance may be overcome by laceration of the perinaeum. On the part of the child, it arrests haematosis, partly by direct action on the placental blood, and partly by the continuous compression of the body ; but the chief danger is paralysis of the foetal heart. It is highly approved by obstetricians at the present time to admin- ister a dose of ergot at the conclusion of the second stage of labor, to insure firm uterine contractions. This practice is held to be the more necessary when previous experience justifies the apprehension of trou- blesome haemorrhage. When post-partum hmmorrhage occurs, it is universally conceded to be the proper thing to administer a full dose of ergot ; but at the same time other measures must be resorted to in order to procure firm uterine contractions, on which alone depends the safety of the patient. In these conditions the ergot is usually admin- istered in substance — one scruple to a drachm of coarsely-powdered ergot infused in a cup of hot water, the whole being drunk by the pa- tient. From 3 j to § j of the fluid extract may be given instead — the official preparation representing a grain of ergot to the minim. The Hypodermatic Injection or Ergotin. — The subcutaneous injection of ergot has become so important a therapeutical resource that it is necessary to treat the subject in a separate division. The solution employed for this purpose is usually as follows : ^ Ergotinae (aq. ex.), 3 j ; glycerini, 3 j ; aquae destil., 3 vij. M. Sig. : Eight minims contain one grain of ergotin. Squibb has prepared " an ex- tract of ergot which is almost entirely soluble in cold water, and rep- 27 418 EXCITO-MOTORS. resents good rye ergot in the proportion of one grain of extract for five grains of ergot. Sixty grains of this extract, dissolved in two hundred and fifty minims of water — the solution filtered, and made up to three hundred minims by passing water through the filter to wash it and the residue upon it — makes a solution which represents ergot in the proportion of minim for grain, and is of the same strength as the fluid extract of ergot, but is free from alcohol or other irritant sub- stance." This preparation the author has found to be admirably adapted for subcutaneous administration. When the aqueous extract of ergot of good quality can not be obtained, the fluid extract may be used. The rules for the administration of ergot are the same as for other agents applied in this way. In the treatment of haemorrhage, when a prompt effect is desired, the hypodermatic injection is preferable to the stomach administration. In haemoptysis, the injection may be practiced while suitable remedies are administered by the stomach. In hmmatemesis, especially if the stomach be irritable, better results may be obtained by subcutaneous use of ergot than by any form of internal medicine. In post-partum haemorrhage , when to await the action of ergot may endanger the life of the mother, the subcutaneous administration should be resorted to. The happy results which have attended this mode of administration in serious cases, demand that the accoucheur be provided with the necessary appliances for the hypodermatic injection of ergot in every obstetrical case. This mode of using ergot is not only prompter in results, but is more effective in securing uterine contractions and arrest of haemorrhage. The good results which are obtained from the stomach administra- tion of ergot in subinvolution of the uterus and in chronic metritis, are much more quickly and decisively obtained from the subcutaneous administration. Since the memoir of Hildebrandt appeared, numerous cases of successful treatment of uterine fibroids by hypodermatic injec- tion of ergotin have been published. There seems to be no longer any doubt that this agent administered in this way, and less effectively and for a much longer period by the stomach also, has the power to arrest the growth of uterine fibroids, to cause them to atrophy, or to set up such a degree of uterine action as to compel their extrusion as polypi from the uterine cavity. It has, of course, long been known that ergot administered by the stomach may induce such a degree of uterine contraction as to expel a polypus. In those instances in which the hypodermatic injection fails to arrest the growth of a polypus, notable improvement in the amount of the haemorrhage and of the muco-purulent discharge is, at least, a result of the treatment. The author is enabled to speak from personal observation of the excellent results obtained by this mode of treatment in many cases. ERGOT. 419 From two to six grains of the aqueous extract of ergot (ergotin) may be injected under the skin in these cases of uterine fibroids on alternate days, or thrice or twice each week. The abdomen is usually preferred as the site of the injection. More or less pain is experienced at the moment of the insertion of the solution, and an indurated spot, which may be more or less sore, will remain for a week or more. Sup- puration may result from the injection, but it is not a frequent accident. The hypodermatic injection is an effective mode of treating vari- cocele. About two grains of the extract in solution is a suitable dose. The needle is inserted so that its point will rest among the dilated veins, but care must be taken not to puncture a vein. Very severe pain follows, and there may be great faintness, but the effects subside in a few hours unless considerable swelling should ensue, which is quite usual. A single injection may cure a very extensive varicocele, and more than two are rarely necessary. Varicose veins in other parts, especially of the inferior extremities, have been cured by the same treatment. The following is the mode of proceeding in these cases : the needle is inserted under the skin, in close juxtaposition to the enlarged vein, and the fluid is so injected as to lie alongside of the vein, but not to enter it. The cure which follows in many of these cases has been ascribed to the inflammatory swelling which takes place, but there is, doubtless, besides this effect, a dynamical influence ex- erted on the vessel-walls. It has lately been asserted that deficient erections and loss of the capacity for coitus are not unfrequently due to enlargement of the dorsal vein of the penis, and consequent too rapid emptying of the veins of the erectile tissue. Acting upon this plausible suggestion, the author has practiced the hypodermatic injection of ergotin about the dorsal vein of the penis, and he has had apparently excellent results. Before closing this article, it may be advisable to recall to the read- er's attention the fact that the hypodermatic injection of ergot, or its internal administration in large doses, may cause such tonic contrac- tion of the sphincter vesical as to render micturition impossible. Care- ful inquiry and frequent examinations of the hypogastric region should be made during a course of ergot preparations. Authorities referred to : Bailly. Prop. M.

JExtractum Ustilaginis Maydis Fluidum. — Fluid extract of usti- lago. Dose, Tii x — 3 j. Composition. — No proper investigation has yet been made of the chemical constitution of ustilago. Some of the ingredients found in ergot have been detected, as secaline so called, and trimethylamine ; but the latter is regarded by others as a decomposition product and not existing preformed. Besides other substances, Parsons has separated an acid, which he regards as similar to the sclerotic acid of Dragen- dorff, and a substance soluble in ether but not in alcohol. Physiological Actions. — Ustilago has been made the subject of physiological investigation by Mr. (now Dr.) Ripley C. Hoffman, of Iowa, in the laboratory of experimental therapeutics of Jefferson Medi- cal College, under the supervision of the author. The research em- braced cold- and warm-blooded animals. The preparation used was the fluid extract, made by John Wyeth and Brother, of Philadelphia, and it proved to be quite active. Both in cold- and warm-blooded animals, ustilago acts as a spinal excitant, causing convulsions of a tonic character. It also heightens sensibility and the reflex function, so that the least irritation of the skin induces general tonic convul- sions of the tetanic or strychnic character. Frequent irritation and repeated convulsions rapidly exhaust the animal. On the other hand, quiet, darkness, and relief from all irritation, diminish the severity of the convulsions, and prolong life, if not prevent a fatal result. Death may ensue in a convulsion by tetanus of the respiratory muscles. Muscular tremors, general, occur in warm-blooded animals, and mus- cular weakness (paresis) appears in the intervals between the convul- sions. The irritability of the motor nerves, and toward the end, of the sensory nerves also, declines, but is not entirely lost, and the contrac- tility of the muscles lessens somewhat. That the convulsions are spinal, is a fact proved by destroying the cord in a frog, before admin- DIGITALIS. 421 istering the medicament, when no muscular action of any kind takes place. Section of the medulla or decapitation does not prevent the occurrence of the convulsions. Ustilago slows the heart, and by numerous control experiments this action was shown to be due to stimulation of the pneumogastric and its terminal ganglia. It dilates the pupil, and affects the acuteness of vision for near objects. We have no exact data in regard to the action of this agent on the uterine system. An impregnated cat, dying by a merely lethal dose slowly, did not abort ; but it is said that pregnant cows and bitches, after eating ustilago, have dropped their young. The modes of dying are two : in the tetanus ; by exhaustion. In the former, the respiration is arrested, violent tonic extension of the voluntary muscles takes place, the head being drawn back, the toes incurved. In the latter, there is gradually increasing paresis between the convulsions, and slowing of the heart's action. The difference is largely due to the dose and rapidity of administration. A lethal dose for a rabbit weighing 25 ounces seems to be one drachm of the fluid extract. Therapy. — If Dr. Hoffman's study of the action of the fluid extract be confirmed by others, ustilago must occupy an important position as a remedy, possessing as it apparently does the powers of nux-vomica and of ergot combined. It is indicated in the several groups of cases to the treatment of which these remedies are now applied. Digitalis. — The leaves of Digitalis purpurea Linne (Nat. Ord.

The crystalline digitaline (Nativelle's digitaline), physiological investigations have shown, is really an active principle which represents all of the powers of the drug. This occurs in nee- dle-shaped crystals, and has an extremely bitter taste. 422 EXCITO-MOTORS. According to Schmiedeberg, digitalis contains digitonine, which strongly resembles saponine ; digitaline, which is insoluble in water, and is the chief constituent of Homolle and Quevenne's digitaline ; digitale'in, which is readily soluble and has the same action as German digitaline ; digitoxine, the most powerful, and is the principal constit- uent in Nativelle's digitaline. Koppe has examined the action of digi- taline, digitalein, and digitoxine, and finds that they agree in their action, and with the crude drug, but differ in degree of activity. Digitalinum. — Digitaline. A white, or yellowish-white powder, without odor, and having a very bitter taste. Dose, -£$ — ^ of a grain. Antagonists and Incompatibles. — The cinchona preparations, acetate of lead, the sulphate and tincture of the chloride of iron, are chemically incompatible. Tannic acid and the preparations containing it diminish the physiological activity of digitalis. Opium, aconite, lobelia, and the cardiac paralyzers, antagonize some of the actions of digitalis, but the antagonism does not extend throughout the whole range of their influence. The most complete physiological antago- nism exists between digitalis and saponine (KOhler), the active princi- ple of Saponaria officinalis, closely allied to senegine. Aconite antag- onizes the cardiac action of digitalis, and morphine, also, to a less degree. Synergists. — Cold, ergot, belladonna, increase the physiological activity of digitalis. Physiological Action. — Digitalis has a disagreeable, bitter taste. In considerable doses, of the infusion, for example, it disturbs the stomach and gives rise to nausea and vomiting, and frequently purges. Loss of appetite results from its medicinal administration in some subjects, even when the quantity is small ; but, in others, the appetite is increased. The active constituents of digitalis diffuse into the blood, but nothing is definitely known as to the action of this agent on the composition of the blood, or the influence which it has, if any, on the morphological elements. On the heart digitalis exerts a peculiar action which requires atten- tive examination : it prolongs the diastole and increases the vigor of the systole. A lethal dose arrests the heart in systole, inducing a tetan- ic state of the heart-muscle. While digitalis increases the power of the systole, the diastole is prolonged, hence the number of pulsations per minute is reduced. With ordinary medicinal doses this slowing of the heart may be considerable, and the pulsations may descend to fifty or even forty per minute. Microscopic examination of the mesentery (Ackermann) and of the web of the frog has definitely ascertained that a marked contraction of the arterioles takes place under the influ- ence of digitalis. The increased power of the systolic contraction of the heart and the greatly-increased resistance in front from a narrow- DIGITALIS. 423 ing of the caliber of the vessels produce, as might a priori be ex- pected, a considerable rise of the blood-pressure. When the pulse is greatly reduced by the administration of large medicinal doses, a change from the recumbent to the upright posture causes a remarkable increase in the number, and diminution in the force, of the cardiac pul- sations. When lethal doses, short of a sudden toxic effect, have been experimentally administered, the slowing of the heart and rise of ar- terial tension first produced are succeeded by a quick, feeble pulse, and fall in the blood-pressure. These results are obviously due to the loss of power (paresis) which results from over-stimulation. A temporary rise of temperature follows the administration of a lethal dose of digitalis, but this rise is soon succeeded by a marked and sustained reduction. Owing to the increased resistance from diminu- tion of the caliber of the arterioles, the actual energy expended by the heart is in part converted into heat. Subsequently the slowing of the circulation, especially through the lungs (Traube), hinders the combus- tion process, and hence the fall of temperature. Digitalis in full medicinal doses produces headache, a band-like feel- ing around the forehead, dizziness, disturbances of vision (mistiness, vibratory movements of external objects, chromatic dispersion, etc.), drowsiness, languor, and a sense of weariness, and it may even cause hallucinations, illusion, and delirium. Digitalis lessens the reflex func- tion of the cord, lowers the sensibility of the nerves, motor and sen- sory, and impairs the electro-contractility of muscles ; but these effects are not produced by medicinal doses, but are toxic in character. As might be anticipated from a study of its physiological actions, digitalis acts like ergot on the enlarged uterus ; it stimulates to ener- getic contraction the muscular fibers, and in this way arrests uterine haemorrhage. On the genital organs of man it has a similar action ; by diminishing the blood-supply to the erectile tissue it lessens the power of erections, and, secondarily, affects the venereal appetite, producing anaphrodisia. Considerable difference of opinion exists as to the influence of digi- talis on the function of nutrition — the metamorphosis of tissue. By some an increase in the production of urea, by others a diminution, has been noted. The truth, most probably, is that it has no real influence on urea formation, and that the variations observed are accidental. The phosphoric acid and chlorides are diminished. In health digitalis af- fects but little the water of the urinary secretion ; according to some the water is diminished, according to others increased. It is difficult to reconcile these opposing statements, in view of the fact which has recently been ascertained by Brunton, that the diuretic action of digi- talis in dropsy is not due to the increased blood-pressure, but to a spe- cial action on the Malpighian tufts. Therapy. — Before entering on the therapeutical applications of 424 EXCITO-MOTORS. digitalis, there are several practical points with regard to the quality of the drug which require attention. Disappointment in the use of digitalis is frequently experienced, in consequence of the inferior qual- ity of the drug prescribed. The wild digitalis is better than the culti- vated. In this country much of the digitalis found in the shops is the plant cultivated and put up by the Shakers. It is very uncertain, and, according to the author's observation, usually inert. The English digi- talis, and the preparations made from it, should alone be prescribed. Digitalis has an undoubted power to arrest hcemorrhage (Leyden). The mechanism of its action is similar to that of ergot ; it slows the action of the heart and contracts the arterioles. In hcemoptysis it is especially useful in the following state of things : frequent expectora- tions of bloody mucus, with occasionally a mouthful of florid blood, accompanied by fever. This group of symptoms is dependent on transudation from a number of small vessels about the site of a pneu- monia due to a tubercular or caseous deposition. The same kind of expectoration, due to pulmonary congestion from mitral regurgita- tion, is amenable to the same treatment. In uterine hemorrhage digi- talis is also serviceable, but it is more especially indicated in menor- rhagia and metrorrhagia of plethoric subjects. Like ergot, digitalis has the power to induce uterine contractions, and hence it has been used successfully to arrest post-partum hemorrhage. Cases of menor- rhagia, of a peculiarly obstinate kind, are caused by mitral regurgi- tation or stenosis, the mechanical result being to increase the blood- pressure in the venous system of the uterus. Digitalis is the appro- priate remedy in such cases. Granules of digitaline may be prescribed for some days previously to the occurrence of the menstrual molimen, but during the attack the infusion of digitalis is more serviceable. In cases of haemorrhage, generally speaking, the infusion is the most ef- fective form in which to employ digitalis. If the symptoms are urgent, a tablespoonful of the infusion may be given every half-hour until four doses are taken. In ordinary cases a tablespoonful of the infu- sion twice a day is a sufficient quantity to maintain a constant physio- logical effect. In the treatment of hemorrhage, digitalis may be combined with other remedies which are synergistic. 1^ Infus. digi- talis, § ij ; tinct. krameriae, ext. ergot ib fluidi, aa § j. M. Sig. : A tablespoonful pro re nata. In purpura and the hemorrhagic diathesis, digitalis is useful when given conjointly with restorative medicines ; but, as a dyscrasia exists on which the extravasations of blood depend, it is obviously neces- sary to correct this state of things, in order that the patient shall be benefited by a remedy which gives tone to the heart and vascular system. The most important uses of digitalis are in cardiac diseases. In general terms it may be said that it is indicated when the action of the DIGITALIS. 425 heart is rapid and weak and the arterial tension low, and is contrain- dicated when the action of the heart is vigorous and the arterial ten- sion high. In simple hypertrophy, which is compensatory, digitalis has no utility. In stenosis of the aortic orifice, with compensatory hypertro- phy, it is not only useless, but it may give rise to serious symptoms, and even cause a fatal result, if administered in doses sufficient to produce physiological effects (Fernet). When stenosis of the aortic orifice leads to incompetence and regurgitation of the mitral, then digitalis may be used with advantage. As respects the nature of the cardiac lesion merely, digitalis is useful in dilated heart with incom- petence of the mitral, in disease of the mitral orifice with stenosis or regurgitation, and in dilatation of the right heart with incompetence of the tricuspid. As respects the mechanical difficulties which ensue from cardiac lesions merely, digitalis is useful, by reason of the in- creased power which it gives the auricles and ventricles to empty their respective cavities, and the longer intervals between the pulsations, which enable the auricles more perfectly to discharge their contents into the ventricles. The mechanical difficulty consists in a deficiency of blood (ischcemia) on the arterial side, and a stasis of blood on ehe venous side, of the systemic and pulmonary circulation. Digitalis, therefore, assists in the " compensation," or, in other words, by its ac- tion on the heart restores the mechanical balance of the circulation, deranged by the cardie lesions. As respects the rational symptoms of heart-disease, digitalis is useful when the action of the heart is rapid and weak, the tension of the pulse low, when there are cough, diffi- culty of breathing, a dusky countenance, pulsating jugulars, scanty and high-colored urine, and general dropsy. As a rule, it may be stated that the rational signs furnish more conclusive indications of the need of digitalis than the physical. If given in suitable cases, the action of digitalis in heart-diseases is most conspicuous for good ; but careful consideration should be given to the conditions detailed above if the practitioner would procure thoroughly satisfactory results. The form in which digitalis is prescribed is most important. The infusion is the best form in cases of cardiac disease with dropsy. It should be given in tablespoonful doses, twice a day, until some characteris- tic physiological effects are produced. After the subsidence of the severe symptoms, digitaline-granules may be substituted for the infu- sion, or the powder of the leaves may be given in pill-form. As very decided anaemia is present in these cases, the best results are obtained by a combination of digitalis with quinine and iron.

The antipyretic effect of digitalis is a fact much insisted on in Germany (Traube, "Wunderlich, Thomas, Liebermeister, etc.). In the 426 EXCITO-MOTORS. recent elaborate work of Husemann digitalis is classed with the Fie- bermittel — the " antipyretica." The results which have followed its administration as an antipyretic in fevers (typhoid, typhus, etc.) do not, it appears to the author, justify its use in these maladies, notwith- standing its power to lower the temperature. Prof. Leyden regards it as unsafe as an antipyretic. The indications for its use are, ac- cording to Liebermeister, just the opposite of those which obtain in cardiac disease ; that is, " digitalis is only to be used in those cases of typhoid fever in which there is no considerable degree of cardiac weakness." He usually gives from eleven to twenty-two grains, ex- tended over a period of about thirty-six hours. In scarlet fever the utility of digitalis is very great ; it lowers the temperature and maintains the action of the kidneys, thus obviating the two principal sources of danger in that disease. Dr. Daniel Lewis, of New York, influenced by the author's opinions on this point, system- atically used digitalis as the chief remedy in an epidemic of scarlet fever in New York, and presented the results in a paper submitted to the State Medical Society. While the mortality from this disease, for the city at large, is 23 per cent, for Dr. Lewis's cases it was less than 11 per cent. From a teaspoonf ul to a tablespoonf ul (according to age) of the infusion every two, three, or four hours, is a suitable mode of ad- ministration. If uraemia occur, the infusion is the proper remedy, con- joined, of course, with other means. The author has seen most excel- lent results from a poultice of digitalis-leaves, applied to the abdomen and back, in cases of urmmic convulsions, the patient being unable to swallow, or the stomach so irritable as to reject all medicines. Digitalis has been used with success in erysipelas, but it is by no means equal to belladonna in this affection. In rheumatic fever the testimony in favor of the use of digitalis is certainly very strong. It lowers the temperature, and apparently ma- terially shortens the duration of the disease. It may be given in powders — two grains every four hours — or a corresponding quantity of the infusion. In rheumatism, as in every other affection, very prompt effects do not follow the use of digitalis ; a day or two must elapse before any marked reduction of temperature takes place, but a cessation of the joint-trouble may be looked for in seven to ten days. Digitalis is more particularly useful in the cardiac compilations of acute rheumatism, when irregular and feeble action of the heart, diffi- cult breathing, cyanosis, and general oedema, are present. The follow- ing is a prescription of Oppolzer in this condition : 3 I n £ digitalis, 3 i j ; liq. potassii citrat., § jss ; acet. scillse, | ss. M. Sig. : A table- spoonful every four hours. Digitalis has recently been much employed in inflammatory affec- tions, notably pneumonia. On examination of the reported cases the author finds that the defervescence, produced apparently by digitalis DIGITALIS. 427 from the sixth to the tenth day, occurred at the time when the crisis in pneumonia is to be expected, and hence it is difficult, if not impos- sible, to estimate the precise share which the remedy had in the results. That digitalis has any power to prevent the deposition of fibrinous material, to prevent or check the migration of the white corpuscles, or to arrest the multiplication of the cellular elements of inflamed parts, seems to the author highly improbable. That it may be useful to com- bat some of the symptoms — high temperature, ischaemia of the arterial system from pulmonary obstruction, and low tension of the vessels — may be well admitted. There is considerable evidence to show that digitalis is serviceable in chronic bronchitis with interstitial pneumonia (fibroid lung), when accompanied with difficult breathing, secondary dilatation of the right cavities, and general anasarca. It diminishes the cough and expec- toration, tones up the weakened and laboring heart, and reduces the oedema. That digitalis has any curative power in pulmonary tubercu- losis or caseous pneumonia, can hardly be credited, notwithstanding the claims which have been put forward. It may be used as an anti- pyretic when there is much hectic, but the derangement of the intes- tinal canal produced by it is a most serious bar to its employment in phthisis. Some important results have been obtained by the use of digitalis in nervous diseases. The congestive form of hemicrania may not un- frequently be permanently relieved by the persistent use of digitaline- granules (one sixtieth of a grain bis die). Acute maniacal delirium, chronic mania, and delirium tremens, are disorders of the brain in which digitalis has proved very useful. The conclusions of Dr. Will- iams, of Hay ward's Heath Asylum, are as follow : " 1. That digitalis is a valuable sedative in the treatment alike of recent and chronic mania, and when these forms of disease are compli- cated with general paresis and with epilepsy. " 2. That the average dose of the tincture is from 3 ss to 3 j, and this quantity may be certainly given with impunity for several days, and subsequently — adjusted to the state of the pulse — may be advan- tageously used for several months. " 3. That the indication by which the use of this drug is regulated is the state of the pulse, any marked intermittence requiring its imme- diate discontinuance. "4. That the weakness of the circulation is no indication against its employment ; on the contrary, experience shows that the most en- feebled subjects bear its administration as well as the most robust." In delirium tremens extraordinary doses of the tincture of digitalis have been used with success ( 3 ij — 3 iv), but these large doses are un- necessary. This treatment is most useful in the young and robust, with marked cerebral hyperemia, according to some ; but, according to 428 EXCITO-MOTORS. others, in pale subjects with a tendency to cyanosis, the state of the brain being one of anaemia, with effusion and oedema. According to the author's observation, the latter indications are the more correct. The infusion is doubtless a better preparation than the tincture, and of this a tablespoonful may be administered every four hours. Some supposed cases of arachnitis have been reported cured by digitalis, but grave doubts must exist as to the accuracy of the diag- nosis. Cases of exophthalmic goitre in young subjects, purely functional in character, have been cured by digitalis, and the cardiac irregulari- ties, and the dilatation of the cervical vessels, ameliorated in even in- curable cases. Digitaline is the form in which to employ this remedy, or powdered digitalis may be given in pill, with iron and manganese to remove the anaemia. Since the anaphrodisiac properties of digitalis were ascertained, it has been much used in spermatorrhoea. It is adapted to the same class of cases as those in which ergot has been shown to be so beneficial, viz., feeble erections, frequent emissions, and cold hands and feet. The au- thor has seen better results from the combination of bromide of potas- sium and digitalis, in the spermatorrhoea of plethora, than from any other remedies : ^ Inf. digitalis, § viij ; potassii bromidi, § j. M. Sig.: A tablespoonful morning and night, and, after^a week, at night only. Digitalis is one of the most generally useful remedies in dropsy which we possess. It is, of course, specially indicated in the mechanical dropsy of valvular lesions. In renal dropsy from acute desquamative nephritis (tubal nephritis) " of all drugs, digitalis is of the greatest value," and the best form in which to administer it is the infusion. Several days usually elapse before very decisive results are achieved, but the flow of urine is, then, often enormous. The fact that, contrary to what has been heretofore believed, digitalis has a direct action on the glomerule of the kidney, is of great interest in this connection. The author has seen very favorable results from the use of digitalis in granular degeneration of the kidney when dropsy supervened, but its use in this disease requires caution in consequence of the fact that the elimination of urea and of the chlorides is retarded by this agent. The so-called Cumulative Effects of Digitalis. — The author agrees in opinion with those who hold that digitalis is not a cumulative poison in the sense in which this term was formerly used. Doses of digitalis frequently repeated, so that the effect of one is added to those before given, will certainly produce toxic symptoms. In this sense opium, belladonna, strychnine, etc., are cumulative poisons. If full doses of digitalis are given at proper intervals, and the effects of one dose are permitted to cease before the next is given, no accumulation will take CONYALLARIA. 429 place. Sudden toxic symptoms are developed as follows : When, after the administration of large doses, the pulse is much reduced in the re- cumbent posture, on rising, the heart is suddenly found unequal to maintaining the circulation in face of the increased resistance in the arterioles and against the force of gravity. It must not be forgotten, further, that the irritability of the vaso-motor nervous system may be destroyed by over-stimulation by digitalis, and lethal effects be pro- duced in this way.

Convallaria. — All parts of the plant of Convallaria majalis (lily- of-the-valley). (Not official.) The Preparations. — It is a remarkable fact that different proper- ties are possessed by extracts made from the various parts of the plant. An extract made from the root has very powerful emeto-cathartic property, while it but little affects the action of the heart. The same fact is true, to a less or greater extent, of extracts from the whole plant. This emeto-cathartic action is due to the presence of a rather acrid resin, and hence for the purpose now intended to be subserved by the administration of convallaria the preparation used must be freed from this resin. An extract prepared from the flowers and 430 EXCITO-MOTORS. stalks, mixed with a third of their weight of leaves and root, is, ac- cording to Langlebert, the best preparation, when deprived of the resin. In this shape it is a solid extract, has a shining black color and a bitter taste, and is freely soluble in water and alcohol. Extractum Convallarice. — Extract of convallaria. Dose, gr. v — gr. xv. An infusion of the flowers, leaves, and stems is also used. Troitz- ky employed several formulas in his trials — from two to four scruples of convallaria to four ounces of water. Infusum Convallarioe. — Infusion of convallaria (convallaria, 50 parts ; water, 200 parts). Dose, a tablespoonful. Another formula is eight ounces of convallaria to a pint of boiling water, which is twice the strength of the above. As the active principle presents many advantages, this will proba- bly be preferred for administration in cardiac affections. Composition. — In 1858 Walz announced the presence in this plant of two glucosides — convallarin and convallamarin. There are impor- tant differences in the qualities of these substances. The former, con- vallarin, occurs in colorless, rectangular prisms, is slightly soluble in water, but freely so in alcohol. Convallarin, as Marme first ascertained, is a purgative in doses of three or four grains (Husemann). It is probable that the presence of this glucoside in the resin is the secret of the cathartic property of this substance, in part at least. Conval- lamarin is not cry stalliz able, is a white powder, bitter, and freely sol- uble in water and alcohol, but not in ether. The dose when admin- istered by the stomach will range from one fourth of a grain to two grains ; but further investigations are needed to decide this point. This is the principle of convallaria, to which its cardiac actions are due. It is probable that the perfectly pure alkaloid possesses much greater activity than the dose above stated indicates. Physiological Actions. — For some time no other powers were attributed to convallaria than those of a cathartic intermediate in action between scammony and aloes. In Russia it has long been known as a remedy for dropsy. This fact finally induced Troitzky and Bojojawlensky to study its action more closely, and Prof. Bot- kin, of St. Petersburg, subsequently confirmed their researches. It was not, however, until Prof. See undertook the study of its powers and actions, that general interest was aroused, although Marme had, as is stated above, some time before, given an accurate account of the physiological actions of convallaria. Since the publication of See's observations, the actions of this medicament have been inves- tigated by various English and American observers. From these sources, and some personal studies, the author makes up the follow- ing account : Notwithstanding the emeto-cathartic action, if the extract freed CONVALLARIA. 431 from the resin, or convallamarin, the active principle, is given, no dis- turbance of the stomach occurs. It stimulates the appetite somewhat, and digestion is not impaired. An increase of peristalsis occurs, and the evacuations, without being loose, become easy. In warm-blooded animals it slows the heart and raises the arterial tension. At the same time the respiratory movements are rendered more full and somewhat less frequent. These effects are due to stimulation of the vagus, but the nerve does not lose its irritability. If the dose be lethal, after this first stage, the heart becomes irregular in rhythm, the force of the cardiac contractions varies, and the respirations are disturbed, inspiration growing deep and prolonged, owing to spasm of the inspir- atory group of muscles (See). In the third period of the action, just before death, the arterial tension rises very high, but the pulse is ex- ceedingly rapid ; then the pressure falls, the respiration growing deeper and very slow, and the heart stops in systole, before the breath- ing finally ceases. The vagus does not wholly lose its irritability, but near the end a strong faradic current does not stop the heart. The irritability of the motor and sensory nerves remains unaffected, and the muscles preserve their contractility. The pupil is unaffected and the functions of the brain are undisturbed. The diuretic effect of convallaria is very constant and decided, a fact long known in Russia, but no change occurs in the composition of the urine. Therapy. — In suitable doses — 15 to 25 grains of the extract — con- vallaria slows the heart-beats, and often restores the normal rhythm of the heart when disturbed, increases the energy of the cardiac con- tractions, raises the arterial tension, and at the same time the respira- tory movements acquire increased force and volume. These impor- tant therapeutical effects are wrought without affecting the functions of the brain and spinal cord. It is also a prompt and certain diuretic, increasing the discharge of all the urinary constituents. The therapeu- tical indications based on these physiological actions are the follow- ing : Palpitation, disordered rhythm, or vehement action, dependent on impaired function of the pneumogastric, or on hypertrophy of the mus- cular walls ; narrowing of the mitral orifice (mitral stenosis) or insuf- ficiency of the mitral valves, with stasis in the venous circulation, with or without spasmodic breathing ; dilated heart, with or without fatty change or sclerosis ; in all cardiac affections accompanied by dropsy (See). The signal advantage which it offers over digitalis is the absence of danger from its administration, and the freedom of the cerebro-spinal axis and the digestive organs from disturbance. It has now been used in the maladies above mentioned by numerous observers in various parts of the world ; and, although the reports are not uniformly favorable, there can be no doubt that we have in con- vallaria an important addition to our resources. 432 EXCITO-MOTORS.

Tinctura Cimicifugce. — Tincture of cimicifuga. Dose, 3 ss — 3 ij. Composition. — When fresh, the root contains a volatile oil, which possesses in a high degree the characteristic odor of the drug. A true active principle has not yet been isolated, yet Conard has obtained a neutral substance, crystallizable, and having a very acrid taste. The so-called cimicifugin is nothing more than an impure resin, obtained by precipitation from the tincture by the addition of water. The root contains resin, coloring matters, tannic and gallic acids. Antagonists and Incompatibles. — As the preparations of cimici- fuga contain tannic and gallic acids, they are incompatible with the salts of iron. Stimulants, as alcohol, ammonia, antagonize cimicifuga therapeutically. Synergists. — In its action, although feeble, cimicifuga lies between digitalis and ergot. Its physiological effects are increased by cold, digitalis, ergot, belladonna, etc. Physiological Actions. — The taste of cimicifuga is bitter and astringent, with an after acrid feeling. In small doses, without pro- ducing any sensible physiological effect, it promotes the appetite and digestion. In full doses it increases the gastro-intestinal secretions. On the heart and circulatory system, cimicifuga has an action not un- like digitalis, but less powerful : it slows the heart-beats but increases their force, and elevates the tension of the arterial system. Its effects on the nervous system, when administered in large doses, are very de- cided. It causes vertigo, dilated pupils, and in many subjects consid- erable soporific and anodyne effects. There is little doubt that it increases the contractility of unstriped muscular fiber in a manner that resembles ergot, but much less energetically. It stimulates the venereal appetite in man, and promotes the menstrual flow in women. CIMICIFUGA. 433 Diaphoresis and increased bronchial secretion are produced by it, and the urine possesses a distinct odor of the drug. In order to procure physiological effects from cimicifuga, it is essen- tial that preparations made from the fresh root be employed. Therapy. — Cimicif uga is an excellent stomachic tonic, and is espe- cially adapted to the treatment of the irritative dyspepsia of drunk- ards. In fevers and inflammatory disorders, when the action of the heart is quick and the tension of the vessels low, cimicif uga may take the place of digitalis, but it is much less efficient than the latter. It is an excellent expectorant, useful in bronchitis and in neuropathic pulmo- nary disorders. 1} Ext. cimicif ugse n., § ss ; tinct. opii deod., 3j ; syrup, tolu., 3 xj. M. Sig. : A teaspoonful every four hours. This combination is efficacious in acute catarrh (common cold), and in acute bronchitis after the more active symptoms have subsided. Good results have been obtained from cimicif uga in phthisis. It would be idle to claim that it is curative ; but, to moderate hectic, to improve the appe- tite, and to facilitate expectoration, it is undeniably of service. It is in that form of phthisis now called caseous pneumonia that cimicif uga can be expected to relieve symptoms, and not in tuberculosis. Dilated heart, fatty heart, languid circulation, oppressed breathing, general dropsy, are conditions in which cimicifuga takes the role of digitalis, and although less efficient, it is safer, especially in the case of fatty heart. Most favorable reports have been made of cimicifuga in acute rheu- matism. Chronic rheumatism, with tumefaction of the joints, lum- bago, intercostal pain, and myalgia, are disorders affecting the mus- cular system, in which this drug sometimes succeeds in a wonderful manner ; yet it very often fails, and we are, unfortunately, unable to indicate beforehand the particular kind of cases in which it is most beneficial. The power of cimicifuga to relieve certain kinds of pain is well established. Neuralgia of the fifth, arising from cold, rheumatic head- ache, ovarian neuralgia, succeeding to suppressed or arrested menstru- ation, etc., are forms of pain in which this remedy is frequently very effective. Puerperal mania, hypochondriasis, and convulsions, due to men- strual irregularities, have been cured by cimicifuga. The greatest successes of this drug have been achieved in chorea. It is useful in those cases which arise about the period of puberty, and are connected with disorders or perversions of the menstrual flow. Cimicifuga relieves the pains of dysmenorrhoza when of the con- gestive variety. Heat of head, flushings of the face, pain in the head, back, and limbs, quick pulse, and nervousness, when due to arrest of the monthly flow, are often remarkably benefited by this agent. It has been used to promote parturient pains, to induce uterine contractions 28 434 EXCITO-MOTORS. after delivery, and to relieve after-pains, but it is inferior to ergot for most of these purposes. It is serviceable in subinvolution of the uterus, and may be given in combination with ergot. The aphrodisiac effects of cimicifuga render it useful in sperma- torrhoea. It is not adapted to physiological spermatorrhoea, which is really a condition of normal plethora, but to those cases in which the organs are relaxed, the erections weak, and the seminal discharges feeble and occur on slight excitement. To obtain curative effects from cimicifuga, it must be administered in sufficiently large doses to produce some of its cerebral effects. Authorities referred to : Davis, Dr. N. S.

This principle is found chiefly in the bark of the root, and of young root. Another principle has also been discovered analogous to atropine, to which the name belladonnine has been given. Ladenburg has shown that belladonnine is identical with the active principle of hyoscyamus, or hyoscyamine. It is identical with atropine in compo- sition, and can only differ in the arrangement of its molecules. The root also contains a fluorescent substance and a coloring matter, which BELLADONNA. 435 has been called atrosin. Atropine exists in the plant in combination with malic acid as Mmalate. Atropina. — Atropine. Is in yellowish-white, silky, prismatic crys- tals, without smell, but having a bitter and acrid taste. It is soluble in three hundred parts of water at 60° Fahr., in twenty-five parts of ether, and in much less alcohol. It has a strong alkaline reaction, and forms cry stall izable salts with acids.

Antagonists and Incompatibles. — Caustic alkalies act on atro- pine, and ammonia is evolved ; they are, therefore, incompatible with the preparations of belladonna. As respects physiological antagonism, physostigma and pilocarpus counterbalance the actions of belladonna in almost the whole range of its influence. Opium — within certain limitations to be hereinafter described — antagonizes the actions of belladonna. In cases of poisoning, the stomach should be promptly emptied by emetics (sulphates of zinc or copper), and the nervous disturbances combated, as they arise, by physostigma, opium, or pilo- carpus. Physiological Actions. — Dryness of the mucous membrane of the nose, mouth, throat, and larynx, is produced by the direct applica- tion of atropine to these parts, and the same effects in a more positive manner follow the stomach or subcutaneous administration. A peculiar bluish appearance of the lips, as well as dryness, the author has fre- quently observed. Nausea is occasionally produced by belladonna, but this effect is probably due to cerebral disturbance. Dryness of the mucous membrane of the stomach and intestines is doubtless produced by belladonna, but increased secretion occurs subsequently, for the stools are rendered more liquid, and are also voided more frequently. Increased peristalsis is most probably a result of the action of bella- donna on the unstriped muscular fiber of the intestines. The active principle of belladonna (atropine) is an extremely diffus- ible substance. What changes it induces in the blood, if any, are not known. It affects the circulation in a remarkable manner. In some subjects a decided slowing of the heart takes place immediately after the administration of a considerable dose (atropine hypodermatically), and in all, most probably, an instantaneous retardation of the pulse- rate, but a very decided rise in the number of pulsations quickly fol- lows. Not only is the number of the heart-beats increased, but their vigor also, and the area over which the pulsations are distributed is enlarged. It has been conclusively shown that the increased action of the heart is due, first, to stimulation of the cardiac ganglia of the sympathetic, and, secondly, to a paralyzing action on the pneumogas- 436 EXCITO-MOTORS. trie terminal filaments. In other words, the motor power of the heart is increased in activity, and the inhibiting control is lessened. The stimulation of the vaso-motor centers by belladonna, or atro- pine, is not confined to the cardiac ganglia, but extends to the vaso- motor ganglia throughout the body, and a general rise of blood-pressure takes place owing to a contraction of the arterioles. It is a singular fact that the influence of atropine rapidly produces a state of over- excitation, and the irritability of the vaso-motor nervous system, at first increased, soon diminishes ; the action of the heart becomes weak, the vessels dilate, and the blood-pressure falls below the normal. In large medicinal doses this effect is easily seen, and, in lethal doses in animals, it may be most certainly demonstrated. As regards the function of respiration, atropine increases the num- ber and depth of the respiratory movements, but the increase is not in the same ratio as is the elevation of the pulse-beat. The more rapid action of the heart, the increased respiratory movements, the contrac- tion of the arterioles, result in an increased supply of blood to the periphery, more rapid nutritive changes, and consequent elevation of temperature. The rise in temperature in man, from a full medicinal dose, is from \° to 1° Fahr. This increased body-heat is not long maintained ; with the fall in the blood-pressure (vaso-motor paresis), there ensues a diminution in temperature. In persons of a light complexion, more especially in women, a full dose of atropine is frequently followed by a diffused redness of the skin, not unlike the rash of scarlatina, but wanting in the punctated character of this specific eruption. Redness of the fauces, and some difficulty of swallowing, owing to the dryness of the mucous mem- brane, occur at the same time, rendering the similitude to scarlet fever very striking. The flush of atropine succeeds to a marked but tem- porary pallor, which is the first effect, and is a symptom of the vaso- motor paresis which succeeds to the vaso-motor stimulation. The bel- ladonna rash is sometimes followed by desquamation. Dilatation of the pupil is a conspicuous effect of atropine. Whether dropped into the eye, introduced into the stomach, or injected under the skin, prompt and decided dilatation of the pupil follows. A much smaller quantity suffices to produce this effect, when applied directly to the eye. Paresis of the muscle of accommodation is caused by atropine, and this agent also lessens the intraocular pressure. It has been conclusively shown that atropine produces these remarkable effects by an action on the peripheral filaments of the nerves of the iris, and net on its muscular fibers ; atropine paralyzes the oculo-motor nerve end-organs, and stimulates those of the sympathetic. The cerebral effects of belladonna are very characteristic. Head- ache, vertigo, illusions, hallucinations, a busy delirium, sometimes somnolence, are produced by large doses. The vision is usually lost, BELLADONNA. 437 the pupils are dilated to the utmost, the eyes are brilliant and staring. Muscular weakness, inco-ordination, and complete motor paralysis oc- cur ; but sensation is not destroyed ; although occupied with fancies aud illusions, the patient may be indifferent to moderate irritation. The delirium which occurs has a peculiar character : it may be gay and laughing, or busy, the patient being incessantly occupied with a single object or idea ; or it may be noisy and furious, the patient fight- ing and striking all who approach. In lethal doses convulsions may occur, or profound stupor may result after a period of delirious excite- ment. The voluntary muscles are not affected by belladonna. The mus- cular paresis which results from the administration of this drug is due to its action on the motor nerves, but the excitability of these nerves is diminished only, and not wholly destroyed. Both the motor-nerve trunks and the end-organs are affected. The sensibility of the sensory nerves is also impaired, but is not diminished to the same extent as is that of the motor nerves. Although the action of belladonna is so largely paralyzant, it is not exclusively so, and, under certain circumstances, a tetanic action very similar to that caused by strychnine is developed. In frogs, a day or two after the induction of paralysis by the subcutaneous injec- tion of atropine, the tetanic state occurs. When this state is reached, although the frog lies perfectly limp and motionless if undisturbed, an irritation applied to the periphery will at once cause general tetanic rigidity and spasms. The author was the first to show that this con- dition of the nervous system is attained in frogs an hour or two after the conjoined administration of atropine and physostigma (eserine). Atropine, by virtue of the greater than normal transmission of blood through the tissues, increases metamorphosis, and the results of this are represented in an increased elimination of the products of waste. Atropine is eliminated chiefly by the urine, and the urine of an atropinized animal will dilate the pupil of another animal. Therapy. — In mercurial ptyalism, and the ptyalism of the preg- nant state, a few drops (five to ten) of the tincture of belladonna, given every four to six hours, or a corresponding quantity of atropine, will cause the excessive secretion to diminish, and even dry up, and will thus relieve a very disagreeable symptom. Gastralgia, as well as the pain which accompanies gastric ulcer, is often happily relieved by atropine. I), Atropine sulphatis, gr. j ; zinci sulphatis, 3 ss ; aquse destil., I j. M.

The extract of belladonna is a useful addition to purgatives, to di- minish the harshness and at the same time to increase the effectiveness of their operation. Belladonna has the power to increase the peristal- tic movements and to allay irregular or spasmodic movements. It is, therefore, used to overcome habitual constipation. A pill containing a half -grain of extract, taken at night, will sometimes succeed, but it is generally better to combine it as follows : t> Ext. belladonnae, ext. nucis vomicae, ext. physostigmatis, aa gr. iij.

An addition of a half -grain of aloine will, of course, increase the action of this pill, and may be added when there are great torpor and inaction of the intestines. When, in affections of the gastro-intestinal apparatus, acids are in. dicated with atropine, they may be combined as follows : I£ Acid, muriat. dil., § j ; atropine, gr. ss. M. Sig. : Five drops in water before meals. Such a prescription is useful in heart-bum, water- brash, etc. Harley advises the use of atropine as a cardiac stimulant ; but the fact that this agent exhausts the irritability of the cardiac ganglia after a period of excitement requires discrimination in its use. Not- withstanding this objection, atropine may be given to counteract a sudden and temporary depression in the heart's action — as, for exam- ple, in the collapse of cholera, in which it has been employed success- fully by the hypodermatic method. Belladonna is a remedy of great efficacy in certain acute inflamma- tions of the air-passages. No remedy gives such prompt and sustained relief in acute nasal catarrh with profuse watery secretion. To adults, the best method of administration consists in giving a first dose of five drops of the tincture, and repeating a drop or two drops every hour until atropinism is produced. This remedy is also very admirably adapted to the treatment of ordinary sore-throat. As a constant phys- iological action of belladonna is redness and dryness of the fauces, its therapeutical action, in sore-throat with increased secretion, is anti- pathic or substitutive ; or, as it may be more scientifically expressed, the action of belladonna is the physiological antagonist of the disease- action. When there is much fever it is useful to combine aconite with belladonna. 5- Tinct. aconiti rad., 3 j ; tinct. belladonna, 3 ij. M. Sig. : Four drops in water every hour or tico. That form of aphonia which is due to fatigue of the vocal cords may be removed very speed- ily by a morning and evening dose ( T J ¥ — ^ of a grain) of atropine. Not unfrequently hysterical aphonia may be quickly cured in the same way. BELLADONNA. 439 There is much to be expected from the use of belladonna prepara- tions in whooping-cough. The best form for administration is a solu- tion of the sulphate of atropine (gr. j — § j of water. Dose, tij, ij — tti iv). This remedy is not adapted to all cases, and is most effective in the spasmodic stage. In order to be curative, physiological effects must be produced. The good results of atropine in whooping-cough are most obvious in those cases characterized by profuse bronchial secretion. Belladonna gives great relief in paroxysms of asthma, and in the spasmodic difficulty of breathing which accompanies emphysema. Ac- cording to the author's observation, when the bronchial mucous mem- brane is deficient in secretion, the pulse much accelerated, the skin dry and hot, belladonna rather adds to the distress ; and its good effects are most conspicuous when there are abundant expectoration, a cool and moist skin, and a quiet pulse of low tension. In asthma, atropine may be injected subcutaneously, or the belladonna-leaves be used by the method of fumigation. Belladonna-leaves, dipped in a saturated solution of niter and then dried, may be burned in a close apartment, the patient breathing the fumes until relief is obtained. Pastiles are made of belladonna, stramonium, poppy, tobacco, etc. A good for- mula for cigarettes is the following (Trousseau) : Belladonna, grs. v ; stramonium and hyoscyamus, of each grs. iij ; extract of opium, \ of a grain ; cherry-laurel water, a sufficient quantity. The leaves are moistened with a solution of the opium in the cherry-laurel water, and when dry made into a cigarette. Two to four of such cigarettes may be smoked daily. When the paroxysms of asthma occur in the morn- ing, they may sometimes be prevented by the one sixtieth of a grain of atropine at bedtime. The remarkable similarity in the symptoms of atropinism and of scarlatina has led to the use, by homoeopathic practitioners, of bella- donna as a prophylactic against this disease. The points of resem- blance are so superficial, and the differences so wide, that no more striking instance could be adduced of the uncertainty in the applica- tion of the homoeopathic dogma, even admitting its truth. The au- thor is convinced that the so-called prophylactic power of belladonna against scarlatina has no real existence. He has seen too many cases of scarlatina occur in subjects who had been given the remedy freely, to permit him to come to any other conclusion. Belladonna is a use- ful remedy to relieve some of the symptoms in scarlatina. During the stage of eruption it is indicated when the pulse is feeble, the bod- ily powers are depressed, and the rash is imperfectly evolved. In this condition of things — in which carbonate of ammonia is so much used — belladonna also renders most important service ; but it should not be forgotten that these agents are chemically incompatible, and should not, therefore, be prescribed together. 440 EXCITO-MOTORS. In diphtheria, when there is much depression, belladonna is a most excellent remedy. If given before the exudation has spread and con- solidated into membranous plaques, and when a few patches only have appeared on the tonsils, or soft-palate, it seems to have the power to hinder the formation of the exudation. There is no doubt that belladonna has a real curative power in erysipelas. It is especially adapted to idiopathic erysipelas, notably to facial erysipelas, and is less serviceable in traumatic erysipelas. Homceopathists explain this on the doctrine of similars, but the action is really one of antagonism, or substitution. When there is much fever, digitalis or aconite may be combined with belladonna with ad- vantage, and when there is much depression, quinine. I£ Quininae sulph., 3 ss ; belladonnas extract., grs. iij . M. Ft. pil. no. x. Sig. : One every four or six hours. Excellent results have been obtained from the use of belladonna in typhus and typhoid fevers. Graves originally suggested an indication for its use in fevers, which is doubtless serviceable, viz., contracted pupils ; but belladonna has been used, irrespective of this sign, by other practitioners with great success. The tincture is a suitable preparation, and of this from five to ten drops every four hours is a proper dose. According to the author's observation, belladonna is in- dicated when there is much low, muttering delirium, subsultus, and stupor, and is contraindicated in the condition of delirium ferox. Belladonna has important application in the treatment of certain disorders of the nervous system. Sick-headache, due to or accom- panied by spasm of the arterioles — a condition manifested by pallor of the face, vertigo, and tinnitus aurium — is relieved by belladonna. At first the distress may be even increased, but great relief presently follows. This remedy is injurious in the congestive form of sick- headache. The following is a serviceable combination in the cases of sick-headache due to vaso-motor spasm : ^ Atropinse sulph., gr. ss ; chinoidin, 3 j. M. Ft. pil. no. lx. Sig. : One pill tvnce or thrice a day. Although belladonna in the physiological state induces wakeful- ness and busy delirium, in certain morbid states of the brain it is hyp- notic. The indications for its use are as follows : prostration, low state of the arterial tension, languid intra-cranial circulation, a con- tracted pupil, and insomnia, due to the condition of the brain mani- fested by these objective signs. In various kinds of mental disorder, in which the foregoing symptoms are present, much good may be ex- pected from the use of belladonna in moderate doses ; but harm only will be produced by it when there is much vascular excitement. Belladonna, according to Trousseau and Pidoux, is a more efficient remedy in the treatment of epilepsy than the salts of silver, copper, or zinc. They insist that the capital condition of success is perseverance BELLADONNA. 441 on the part of the physician and patient, that belladonna should be given steadily for a year in gradually-increasing doses, and that if amendment is then produced it should be continued through two, three, or even four years. Belladonna is not equal to bromide of potassium in cases of diurnal epilepsy, in epilepsy accompanied by cerebral hyperemia, and in epileptiform convulsions due to coarse or- ganic lesion of the brain. The best results are obtained from it in nocturnal epilepsy, in petit mal, and in pale, delicate, and anaemic sub- jects, with cold hands and feet, blue skin, and weak heart. In neuralgia belladonna affords relief, although not equal to some other agents. Given hypodermatically {see p>ost), it is often very effec- tive. In any case, its use must be persisted in ; full doses are neces- sary, and physiological effects must be produced and maintained for some time. A solution of atropine is the best form for the stomach administration. Dysmenorrhea, when neuralgic in character, and ovarian neuralgia, may be permanently removed by belladonna. It is useful in these cases to combine it with synergistic remedies. !£ Ext. belladonnas, grs. iv ; ext. stramonii, grs. v ; ext. hyoscyami, grs. v; quininae sulphat., 3ij. M. Ft.pil.no. xx. Sig. : One pill tic o or three times a day. When anaemia exists, iron may be added to this formula. No single agent has been as uniformly successful in the treatment of nocturnal incontinence of urine as belladonna. This morbid state is due to several conditions, and belladonna is not equally successful in all : nocturnal incontinence may be due to an excess in the acidity of the urine, which renders it unduly stimulating ; to relaxation of the sphincter vesicae ; to an irritability of the mucous membrane, in consequence of which erroneous impressions are communicated to the brain. Belladonna gives relief in the two last-named conditions. The atropine dissolved in the urine acts locally on the nerves of the mucous membrane, diminishing their irritability ; the sphincter is put into a state of tonic contraction by reason of the systemic effect, which includes, of course, the sympathetic system. The error is often com- mitted of giving too little of the remedy ; systemic effects must be produced, and children, compared with adults, are insusceptible to the action of belladonna. The best form for administration, be- cause less disagreeable and more constant in effect, is a solution of atropine. Nocturnal seminal losses, as respects mechanism of production, making allowance, of course, for difference of seat, have a strong analogy with nocturnal incontinence of urine. This trouble may be considered a morbid state, only, when the losses are frequent and affect the health. Bromide of potassium best relieves spermatorrhoea, so called, when it is largely physiological and due to a normal plethora ; belladonna is most serviceable when the genitalia are relaxed, the 442 EXCITO-MOTORS. emissions flowing without force, and without a distinct dream and orgasm. Atropine is a remedy of the greatest importance in the practice of ophthalmology. As it dilates the pupil, diminishes the intraocular pressure, contracts the arterioles, and acts topically on the sentient nerves, it is obvious that its field of utility is wide, and its therapeutic power great. In phlyctenular keratitis atropine renders the greatest service ; it diminishes the photophobia and blepharospasm, and lessens the blood- supply by contracting the vessels. It has a still more beneficial action in iritis ; it prevents adhesions, anterior and posterior, and by dilata- tion of the pupil so compresses the vessels as to jugulate the inflam- matory process. When the cornea is perforated, herniary protrusion and adhesion of the iris are prevented by dilating the pupil. For these purposes a four-grain solution of atropine is the proper strength for in- stillation into the eye. When it is desirable to suspend the power of accommodation, in cases of hypermetropia to determine the refraction of the eye, and in astigmatism to ascertain the difference in the me- ridians, atropine is used. A weak solution only is employed, to dilate the pupil for a brief period, in order to facilitate the examination of the fundus of the eye. Dilatation of the pupil with atropine is also necessary in the examination of cataract, especially in the early stages of its formation. It should be remembered that strong solutions of atropine instilled into the eyes may, by subsequent absorption, pro- duce atropinism, and to such an extent as to occasion solicitude. In certain affections of the shin belladonna is useful — viz., in the cutaneous neuroses, prurigo, herpes zoster, erythema, and eczema, etc. Cases of these affections which resist ordinary treatment, yield to bella- donna. The tincture, or the alkaloid, in suitable doses, may be given in quantity sufficient to maintain a slight physiological action. Hyper- idrosis (colliquative sweating), unilateral sweating, and other forms of profuse transpiration through the skin, are arrested by the internal and, in some cases, by the local application of the belladonna prepara- tions, as Ringer has shown. No remedy is so generally effective in relieving the sweats of p>hthisis as atropine. The one sixtieth of a grain at bedtime usually suffices. The author was the first to indicate this use of atropine in his "Prize Essay." Not only is atropine antagonistic in action to that condition of the sudoriparous glands resulting in the sweats of disease, but it equally antagonizes the hyperidrosis produced by such drugs as jaborandi. In the treatment of that form of phthisis known as caseous pneu- monia, atropine has an important place, quite irrespective of its power to arrest the sweats. As Dr. Fothergill, of London, and myself, nearly simultaneously ascertained, it has an influence on the progress of these BELLADOXXA. 443 cases, and a curative effect that is often very remarkable. The author has observed with regret that some of those who have found this remedy useless, were entirely mistaken as to the character of the cases in which atropine has proved beneficial. As a remedy for the caseous inflammation, without regard to sweating, the period when the degree of benefit above referred to may be expected from it, is the stage of deposit immediately succeeding the stage of catarrhal inflam- mation, and before softening and extrusion. Hypodermatic Use of Atropine. — The solution usually employed for this purpose is two grains of the sulphate of atropine to an ounce of distilled water, the dose of which ranges from two to five minims. There are two forms of neuralgia in which the subcutaneous use of atropine has been most signally useful : tic-douloureux and sciatica, more especially the latter. Atropine is not as effective in the treat- ment of the neuralgias in general as morphine, and the systemic effects of the former are much more unpleasant than those caused by the lat- ter. Nevertheless, when morphine fails or disagrees with the patient, atropine may be used with confident expectation of its affording re- lief. We owe to Hunter our knowledge of the fact that atropine has a very special utility in tic-douloureux and sciatica. The merely sub- cutaneous injection of atropine does not afford the same degree of relief as its deep injection in the neighborhood of the affected nerve- trunk. Furthermore, a decided impression must be made on the cere- brum, in order to obtain the best results. The largest doses compati- ble with the safety of the patient must be used — generally the one fiftieth of a grain to the one thirtieth. If the remedy is employed in sufficient quantity, and well inserted into the tissues above the nerve, decided curative results may be expected from it in these two forms of neuralgia. When relief follows the injection of atropine, it is apt to be more permanent than when the same degree of relief is obtained from morphine. We have the high authority of Dr. Anstie for the assertion that atropine is exceptionally serviceable in peri-uterine and dysmenorrhoeal neuralgia. Dr. Weir Mitchell asserts that atropine in traumatic neuralgias is " simply useless," and, as his power of ac- curate observation is unquestioned, and his clinical opportunities vast, we may accept this conclusion as final. Muscular cramp, from injuries to the nerve-trunk, are often remark- ably relieved by injections of atropine into the substance of the affected muscles. The so-called "late rigidity," as the result of which the members may be put into very injurious positions, is occasionally re- moved or diminished by the same expedient — viz., injecting a small quantity of atropine (yj-g- of a grain) into the contracted muscles. This result does not ameliorate the condition of the patient to any greater extent than that of affording relief to an inconvenient de- formity. 444 EXCITO-MOTORS. The insomnia of mental disorders, and of delirium tremens, may be overcome by the hypodermatic injection of atropine when the follow- ing indications for its use are present : Coma vigil, great restlessness, weak action of the heart, coldness of the surface, cyanosis, clammy sweat. When there is a condition of hyperemia of the cerebro-spinal centers, excitement with elevated pulse-rate and increase of arterial tension, atropine can only do harm. The treatment of asthma by belladonna, administered by the stom- ach and in the form of fumigation, has already been referred to. The hypodermatic injection of atropine is much more effective. From y-|- ¥ to -g^ of a grain may be used for this purpose ; but, as the relief comes from the systemic effect, it is not necessary to inject the solution in the neighborhood of the pneumogastric, as practiced by Courty. In order to procure the greatest relief, the injection should be made at the be- ginning of the asthmatic paroxysm, and succeeding attacks should be anticipated by inducing atropinism at the first warning of a seizure. Vomiting of pregnancy, when obstinate and resisting other means, is sometimes arrested promptly and permanently by the subcutaneous injection of atropine in small quantity (y^-g- of a grain). Sea-sickness is relieved in the same way. In these maladies, it is better to insert the injection in the epigastrium. Cramp of the hollow muscular organs — hepatic, intestinal, uterine, and rencd colic — may all be relieved by the subcutaneous injection of atropine, but the most satisfactory results are produced by the com- bined use of atropine and morphine. External Application of Belladonna Preparations. — The chloroformic solution of atropine is an excellent external application to relieve pain in nerves superficially situated. fy Chlorof ormi, spts. viui rect., aa 5 ss ; atropine, grs. v. M. Sig. : Apply on lint to painful part, and cover loith oiled silk. The same application to the epigastrium sometimes arrests obstinate vomiting, cerebral or reflex, as, for example, the vomiting of pregnancy, sea- sickness, etc. A belladonna-plaster is an excellent application to relieve the chest-pains of phthisis, to allay irritability of an over-excited heart, to diminish the pains and soreness of lumbago, myalgia, etc. Excessive siceating of a part, as, for example, unilateral siceating of the head, may be removed by brushing over the affected surface a solution of atropine (grs. iv — f j). There is no doubt that belladonna has the power to arrest the secre- tion of milk, in the same way that it stops the cutaneous transpira- tion, for the milk-gland is only an enlarged sebaceous gland whose function is differentiated from that of other sebaceous glands of the body. When it is desirable to arrest the secretion of milk, the gland may be enveloped by a belladonna-plaster, or the ointment of bella- donna may be carefully rubbed into the integument. These are rather BELLADONNA. 445 disagreeable, sticky applications, which soil the clothing. A much more elegant method of applying this treatment is to envelop the breast in lint wet with a solution of atropine, four grains to the ounce of rose-water. As systemic effects may be produced by such an application, when the pupils dilate and the mouth becomes dry, it should be removed. Inflamed breasts may be treated in the same way. The mode of action of the belladonna preparations is quite obvious : the irritability of the terminal filaments of the nerves is allayed by the direct action of the atropine, and the arterioles are made to contract, thus diminishing the blood-supply to the inflamed tissue. Other superficial inflammations are subdued by the same treatment, as, for example, abscesses, boils, carbuncles. A plaster made of bella- donna extract may be kept in contact with the inflamed tissue, or the solution of atropine, above recommended, may be used. Pruritus of the, vulva, vaginismus, fissure of the anus, are some- times relieved, as if by magic, by the use of the atropine solution above recommended. Whenever atropine is used locally for the relief of inflammatory pain and swelling, the efficiency of the application is much increased by the addition of morphine, or morphine and chloral, according to for- mulae to be given hereafter in the article on the latter drug. Secondary Products of Atropine. — Some remarkable products have lately been obtained from atropine by chemical processes. The first step consisted in the. discovery, by Kraut and Lossen, simultane- ously, that atropine may be split up into tropine and tropic acid. Sub- sequently, Prof. Ladenburg succeeded in the synthesis of atropine by a combination of these two secondary j)roducts. If the salts of tropine are treated with dilute hydrochloric acid, alkaloids are produced, to which Ladenburg has given the name tropeins. Homotropine is an alkaloid obtained from the amygdalate of tropine. The artificial atro- pine, prepared as above described, has precisely the same effects as the original alkaloid. Effects of Homotropine. — The preparation of this base now used is the hydrobromate. The physiological action of this new salt has been studied by Ringer and Tweedy, among others. Ringer finds that, like atropine, homotropine paralyzes and tetanizes, but the tetanizing effect, which follows in forty-eight hours or more in the former, occurs at once in the latter. The paralyzing action is not in the nerves or muscles, for they respond to electrical stimulation, but in the cord, which is also the case with atropine. Homotropine, like atropine, in- creases the action of the heart by paralyzing the intra-cardiac inhibi- tory apparatus, and it also antagonizes muscarine. In man there is a marked distinction as regards the action of atropine and homotropine on the heart : while the former accelerates the heart considerably, the latter retards the beat from ten to twenty per minute, and also makes 446 EXCITO-MOTORS. the action irregular. Homotropine also antagonizes the action of pilo- carpine, but it requires relatively more than of atropine to accomplish this result. Ringer sums up his observations with the remark, " Ho- motropine, then, appears to possess many of the properties of atropine, but in a weaker degree." Tweedy remarks that, as regards the action of atropine and homo- tropine relatively on the eye, the action of homotropine on the iris and ciliary muscle is really very powerful while it lasts. It widely and fixedly dilates the pupil in from fifteen to twenty minutes, and it acts on the accommodation in an equally rapid manner. Its effects pass off rapidly, and in twenty-four hours the accommodation is restored, although the pupil is yet a little dilated. The application of homo- tropine solution to the eye is entirely unirritating. For these reasons homotropine becomes a valuable substitute for atropine in ocular thera- peutics, but it can not be substituted for atropine in the general dis- eases in which the latter has been found useful.

The seeds contain a fixed oil in considerable quantity. Antagonists, Incompatibles, and Synergists, are the same as for belladonna. In the case of poisoning by stramonium, which is not uncommon in this country, the seeds, which usually are taken by chil- dren, must be evacuated by an emetic. Unless distinct symptoms fol- low, no further treatment may be necessary ; if, however, marked dilatation of the pupil, hallucinations, and active delirium are produced, the physiological antagonist becomes necessary. Tincture of opium should be administered until some contraction of the pupil, lessening of the pulse-rate, and cessation of the delirium, occur. If then, normal sleep comes on, the pupil, heart, and lungs functionating normally, no further interference will be necessary. In cases of poisoning in chil- dren, it is particularly desirable to employ the opium with caution, since opium narcosis may readily be substituted for stramonium-poi- soning.

The observation of Ladenburg, that hyoscyamine and duboisine are identical, is important, and if confirmed will facilitate the introduction of the latter into practice. As hyoscyamine is diffi- cult to procure and very expensive, and as duboisine, on the other hand, will probably be very readily procured in any quantity, it is certain that the latter will be substituted for the former. Chemical facts of this kind must be acted on with caution. Identity of chemi- cal constitution does not always mean identity in physiological action 448 EXCITO-MOTORS. and in therapeutical power. Differences in molecular arrangement, not appreciable by chemical analysis, may influence, to a great extent, the mode of action. The clinical facts do not, thus far, warrant the adoption of the view that hyoscyamine and duboisine are mutually convertible. Physiological Actions. — As atropine, daturine, and hyoscyamine are similar if not identical in chemical composition and in physiologi- cal action, the remarks already made in regard to the actions and uses of belladonna are applicable to stramonium and hyoscyamus. To these alkaloids must be added duboisine, which by Ladenburg is held to be identical with hyoscyamine. Studied from the physio- logical standpoint, daturine and hyoscyamine are regarded as identical in their effects by Oulmont and Laurent. As daturine is not employed, owing to its scarcity, and as hyoscyamine has been the subject of con- siderable study and clinical observation, we refer, in the following re- marks, wholly to this alkaloid. Hyoscyamine, as it occurs in commerce, prepared chiefly by Merck, of Darmstadt, is in two forms, a yellowish-white crystalline solid, which is represented as chemically pure, and a dark, resinous mass, having a strong, mouse-like odor, which is rather a concentrated ex- tract, but appears to be little if at all inferior to the pure alkaloid. It is recommended by Prideaux to dissolve it in a mixture of sulphuric ether, alcohol, and water, in the proportion of one grain to twenty minims — alcohol eight minims, spirit of sulphuric ether six minims, and water ten minims. It may be administered, hypodermatically, in this form, or, if too strong, by the addition of equal parts of spirit and water ; and it may be prepared for internal use from the above solution, by adding water and any flavoring sirup. The hydriodate is, however, the best form for administration, as it is freely soluble in water. The great variations in the dose of the alkaloid are due to the fact that much of the so-called hyoscyamine is merely a concentrated extract. The dose, by subcutaneous injection, ranges from one six- tieth of a grain to one fourth, and by the stomach from one sixtieth to one grain. Hyoscyamine causes the same dryness of the mouth, dilatation of the pupils, flushing of the face, rapid action of the heart and of the lungs, the busy delirium with hallucinations and illusions, which are caused by atropine, but its effects in these directions are less in degree. In the various observations which have now been made on man, with the considerable doses which have been found necessary in some cases, it has been definitely ascertained that hyoscyamine has somewhat less than atropine of the deliriant action and much more hypnotic effects. As regards the mechanism of its action on the pupil, on accommoda- tion, on the heart and respiration, there is no actual difference between the two alkaloids. HYOSCYAMUS. 449 The elaborate investigations of MM. Oulmont and Laurent have conducted them to the following conclusions : Hyoscyamine and datu- rine act especially on the sympathetic system, in small or moderate doses, stimulating the vaso-motor fibers and raising the arterial ten- sion, and in large doses paralyzing the vessels and lowering the arterial tonus. These effects are produced after section of the vagi. These alkaloids differ in the effect on the heart — hyoscyamine rendering the cardiac movements more regular, and daturine causing intermittence. By direct contact, both alkaloids slow and finally stop the heart's ac- tion. Both accelerate the respiratory movements. In moderate quan- tity both increase the intestinal movements ; in large doses arrest them. As regards the nervous system of animal life, they are both without action on the motor functions, but in toxic doses they blunt the cuta- neous sensibility. They do not affect the contractility of muscular fiber. Their action in dilating the pupil is due to stimulation of the sympathetic, and not to paralysis of the third nerve. The various phe- nomena arising from the administration of these alkaloids are referred by Oulmont and Laurent to the circulatory disturbances — to the in- creased distribution of blood. The action is soon ended, the alkaloids being eliminated by the urine. Notwithstanding the freedom with which hyoscyamus and its alka- loid, hyoscyamine, are given, rarely are there any unpleasant effects. Empis, however, has reported some cases in which toxic symptoms happened from medicinal doses. These must have been examples of idiosyncrasy, for in the discussion which ensued, Joffroy, Damaschino, and others, expressed themselves strongly against the probability of serious effects from doses within safe limits. Therapy. — The possession of decided hypnotic qualities has led to the use of hyoscyamine in the treatment of various mental disorders (Prideaux, Lawson, and others). Prideaux makes the important prac- tical distinction, that it acts with different degrees of rapidity and potency under varying conditions of insanity. In acute mania with depression, one sixteenth of a grain will have a marked effect, while in the excitement of chronic mania large doses will be necessary. In chronic mania with exacerbations, he gives one quarter, one half, and even one grain by the stomach, or one tenth of a grain subcutaneously. The latter mode of administration he regards preferable in these cases. In cases of mania with great motor excitement, and of a destructive character, Prideaux regards hyoscyamine as " the most rapid and reli- able narcotic we possess." In the epileptic mania of the epileptic status, he says, it diminishes the number and violence of the attacks. In delusional insanity he finds it brings about, under favorable circum- stances, mental restoration. In chronic dementia, with destructive tendencies and sleeplessness, improvement is sometimes noted from the persistent use of small doses. Reinhard also has administered this 29 450 EXCITO-MOTORS. agent in the dose of a milligramme (about one fifteenth of a grain) subcutaneously in cases of mania and epilepsy, with distinctly good results. In eight of fifteen cases of mania, calmative effects were produced and permanent good was accomplished ; and in five of twelve epileptics with maniacal attacks, the number and severity of the seiz- ures were lessened. Drs. Sapilli and Riva, eminent Italian alienists, have found hyoscyamine very useful in recurrent mania. Gill, Ringer, and Lawson have also had good effects from hyoscyamine, in suitable cases, as an hypnotic. Stramonium and hyoscyamus may be used like belladonna for the relief of painful affections, the neuralgim ; but they possess no special advantages over their more powerful congener. Oulmont has used the hypodermatic injection of hyoscyamine with remarkable success in several cases of neuralgia, but he does not regard it as more conspicu- ous and rapid in this disease than are opium and belladonna. Stramo- nium is used with advantage in the treatment of dysmenorrhoea. 3 Ext. stramonii, ext. hyoscyami, ext. opii, aa gr. vj. M. Ft. pil. no. xij. Sig. : One pill every three, four, or six hours. This combination gives great relief in dysmenorrhoea, and may also be serviceable in neuralgia. In affections characterized by spasm, as asthma, laryngeal cough, hepatic, intestinal, renal, and uterine colic, stramonium and hyoscyamus may be given with advantage, in place of or in combination with bella- donna. The hypodermatic injection of hyoscyamine or daturine is an excellent expedient for procuring relief in these cases, but these alka- loids are not more effective than atropine. Hyoscyamus, especially in the form of tincture, is frequently prescribed in irritable states of the bladder due to the presence of stone, enlargement of the prostate, and in catarrh of the bladder arising by transference of irritation from the urethra. It should not be forgotten that liquor potassae, so much pre- scribed in a mixture with hyoscyamus, is incompatible. M. Oulmont refers, in terms which may seem to be exaggerated, to the great efficiency of hyoscyamine in the treatment of mercurial tremor, senile tremor, paralysis agitans, locomotor ataxia, and tetanus. In mercurial and senile tremor cures were obtained, but, as might be expected, only amelioration in paralysis agitans, locomotor ataxia, and tetanus. The remarkable benefit obtained from this remedy in paral- ysis agitans is testified to by Empis, Joffroy, Charcot, and many other observers. The dose which Oulmont found effective was the one thirty-second of a grain of hyoscyamine, gradually increased to the one fifteenth of a grain. The hypnotic quality is much more conspicuous in hyoscyamus than in belladonna or stramonium. In children it has long been known that, when opium is not well borne, hyoscyamus is an efficient substitute. Recent experience in asylum practice has shown that hyoscyamus in HYOSCYAHUS. 451 large doses is a very valuable hypnotic. According to Dr. Campbell, two and a half drachms of the tincture are equivalent in hypnotic power to thirty grains of chloral hydrate. In order to procure effi- cient hypnotic effects, from two drachms to an ounce of the tincture is necessary, and this large quantity appears to be free from danger. Extract of hyoscyamus is used in combination with purgatives, with the object — which abundant clinical observation confirms — of render- ing their operation more efficient, and, at the same time, less drastic. The ointment of stramonium is a favorite application to irritable ulcer 'S, superficial inflammations, etc . Hyoscine. — This is a new alkaloid obtained artificially from hyos- cyamus by Ladenburg. It forms a crystalline combination with hydri- odic acid, and an amorphous salt with hydrochloric. These salts dis- solve freely in water. The solution employed by Edfelsen for admin- istration by the stomach contained about fa gr. to the tablespoonf ul, and for subcutaneous injection, y^-g- gr. to one minim. These are suit- able doses for administration. The physiological effects of hyoscine have been studied by Laden- burg, the discoverer ; by Edfelsen, and others. Generally speaking, the effects of this agent correspond quite closely to those of atropine, but in corresponding doses the latter is more powerful. When admin- istered subcutaneously, hyoscine acts in two to twelve minutes, by the stomach in about fifteen minutes. It causes more drowsiness and sopor, and less delirium than atropine, but like the latter dilates the pupil, in- creases the rate of the cardiac and respiratory movements, and red- dens the skin. According to Gnauck, the pulse is first slowed eight to twenty beats per minute, and after ten to twenty minutes rises. The same phenomenon is observed from atropine in some subjects, but is not so pronounced. Dilatation of the pupil does not always occur after the stomachal administration. Sleep comes on in twenty to thirty minutes, preceded by a feeling of lassitude, and is deep and quiet, but is followed by headache and vertigo. Instilled into the eye, hyoscine is a more energetic mydriatic than atropine, dose for dose (Emmert). One part of the hydriodate to one thousand of water is the solution used by Emmert, and this he finds more active than a half-per-cent solution of atropine. Hyoscine has been employed in various diseases requiring a sopo- rific and anodyne agent. In general, it can be used in the same cases as atropine, but, as it possesses more decided antispasmodic effects, it may prove more valuable. By Ladenburg it has been used success- fully in whooping-cough, in asthma, and in enteralgia. Half the cases of whooping-cough were relieved, and all of the cases of asthma were more or less benefited, some decidedly so. In ophthalmic practice, hyoscine can be substituted for atropine. It causes more prompt and decided, but less persistent, dilatation of 452 EXCITO-MOTORS. the pupil, and it is less poisonous (Emmert). It is applicable to the same purposes in eye-diseases as those in which atropine is now em- ployed. Authorities referred to : Bucknill and Tuke.

Duboisia. — Duboisia myoporoides, of the Solanacece. Preparations. — There are no official preparations. It has been used chiefly in the form of extract, and salts of the active principle. The dose of the extract is gr. \ — J. Composition. — The important constituent is an alkaloid — duboi- sine — which possesses the medicinal powers and properties of the plant. It combines with acids to form salts which are freely soluble in water. As regards its chemical relations, duboisine strongly resembles atro- pine, but differs in some particulars ; according to Ladenburg, duboi- sine is identical with hyoscyamine. The dose of a salt of duboisine is yfo- to A of a grain. Antagonists and Incompatibles. — The caustic alkalies destroy the active principle, and consequently prescriptions containing them will be inert, except as to the effects of the alkali. The physiological antagonists are the same as those of atropine ; thus physostigmine and muscarine counterbalance the action of duboisine in almost the entire range of power, and opium in a limited degree. Duboisine antagonizes pilocarpine, as respects, at least, the most conspicuous and important properties of the latter. In case of poisoning, emetics and the stom- ach-pump must be used, and the systemic effects opposed by the sub- cutaneous use of physostigma, muscarine, or morphine, cautiously, and DUBOISIA. 453 possibly pilocarpine ; but further researches are necessary as to the antagonism of the last named. Synergists. — The actions of duboisia are promoted by the other agents of the group, especially by belladonna, stramonium, and hyoscy- amus. The effects of atropine and duboisine correspond to a remark- able extent, but there are points of difference, as follows : Duboisine is twice or more soluble in water than atropine ; it has stronger basic properties, and it reacts differently to sulphuric acid and bichromate of potassa ; it is less irritating to the conjunctiva, dilates the pupil more promptly, and its effects subside earlier (Gerard). Physiological Effects. — Dryness of the mouth, thirst, and some difficulty in swallowing, soon follow the administration of duboisia, and more speedily after the subcutaneous injection of the alkaloid. The pulse is considerably accelerated ; the arterial tension rises, the face flushes, the pupil dilates, and the accommodation is paralyzed. Some frontal headache, tinnitus aurium, giddiness, and restlessness, especially in sleep, are experienced. Certain motor symptoms — uncertain gait, awkwardness of movement in walking, and muscular paresis — occur (Gubler). In animals mental excitement or delirium has been noted, but no confirmatory or opposing observations on man have thus far been re- ported. The tetanic symptoms which occur after some days in frogs poi- soned by atropine, take place under the same conditions from duboisia. The acceleration of pulse and rise of tension first produced by du- boisia do not persist ; the pulse-rate and the tension fall after some hours, the excitement subsides, and a condition of stupor comes on which is not sleep, although it favors sleep (Gubler). I can confirm these important observations on the cerebral effects of duboisia. Therapy. — Thus far duboisine has been used only in ocular thera- peutics. The author has prescribed it in a case of puerperal mania with excitement, on the suggestion of M. Gubler, and with apparent advantage. There was always an increase of the maniacal excitement for a few hours after the hypodermatic injection, but this was followed by the condition of stupor and mental calm. The improvement was rapid, and followed so closely the administration of the remedy that he could not doubt it was propter and not merely post hoc. As respects its use in ophthalmic diseases, it may be stated in gen- eral that duboisine is applicable under the same conditions as atropine, to which it is to be preferred, in many cases, it is probable. The advantages of duboisine, as compared with atropine, are its greater rapidity of action in effecting dilatatio?i of the pupil and pa- ralysis of accommodation, the less irritation of the conjunctiva, and the more rapid recovery from the effects. It is, therefore, much more useful than atropine for determining the refraction of the eye, and for use in ocular therapeutics in general. Some unpleasant cerebral effects have been observed after instilla- 454 CEREBRAL EXCITANTS. tion into the eye (Seely). The author was given the opportunity, by the kindness of Dr. Seely, to examine the patient — the first instance in which such phenomena were observed — who experienced faintness and strange sensations in the head ; but they were entirely subjective and mental, as no change in the circulation or respiration was to be seen. Since that case there have been several examples of the sys- temic action of duboisine after its instillation into the eye. To relieve the night-sweats of phthisis and the various neuroses of the respiratory organs, and to stimulate the action of the heart, du- boisine may take the place of atropine. As an antagonist to mor- phine it is equally as effective as atropine, but, as a hypnotic and ano- dyne, superior to the latter. Authorities referred to : Bancroft, Dr. Joseph.

B.— AGENTS EXCITING THE FUNCTIONAL ACTIVITY OF THE CEREBRUM. To this group belong those remedies usually classed together under the designation of antispasmodics. They are to a slight degree car- diac stimulants ; they increase the cutaneous circulation, and promote diaphoresis ; they also stimulate the bronchial mucous membrane, and favor expectoration. As a result in part of the increased rapidity of the circulation, the functions of the brain become slightly more active, ideas flow more freely, irregular mental excitement and muscular hy- perkinesia are moderated, and an orderly feeling of well-being is estab- lished. These effects are probably in part due to a direct action of these agents on the gray matter of the hemispheres, but our knowledge does not at present permit an exact statement of the nature of this impression. These agents do not in any quantity suspend the func- tions of the brain, and the temporary increase of activity which they produce is not followed by manifest depression. Camphora. — Camphor.

Almost insoluble in water ; freely solu- ble in alcohol, ether, chloroform, and fixed oils ; slightly soluble in glycerin. Composition and Properties. — Camphor is found in colorless, translucent, crystalline masses. One part dissolves in about 1,300 parts of water, but it is freely soluble in alcohol, ethers, oils, chloro- form, bisulphide of carbon, etc. Its odor is peculiar and characteristic. The formula for camphor is the following : C 10 H ]6 O. By distillation with chloride of zinc it is converted into cymol, and by oxidizing agents into camphoric and camphretic acids. Antagonists and Incompatibles. — The addition of water pre- cipitates camphor from its spirituous solution. Alkaline and earthy salts, for example sulphate of magnesium, separate from its solution the small quantity of camphor contained in aqua camphora?. Coffee, the arterial sedatives, cold, and depressing causes generally, antago- nize its physiological action. Synergists. — All the remedies of this group, and alcohol, opium, and narcotic substances, increase the effects of camphor. Physiological Actions. — Applied to the skin, camphor produces redness, heat, and superficial inflammation, if the contact be sufficiently prolonged ; to an open wound its effects are still more severe. Its taste is hot, aromatic, and pungent. In the stomach it causes a sensa- tion of heat, and may excite in large doses inflammation and ulcera- tion. The symptoms common to irritant poisons may, therefore, be produced by camphor. After experimental doses in animals camphor has been detected in the blood of the mesenteric and portal vein, but not in the chyle or urine. In moderate doses (medicinal) it increases the action of the heart, elevates the arterial tension, and promotes cutaneous transpiration ; it also produces mental exhilaration, even a gay and lively intoxication, and allays pain. In toxic doses, in addi- tion to the local irritant action on the gastro-intestinal mucous mem- brane, and the consequent systemic effects, it lowers the pulse, the skin becomes pale, and the surface cold and moist, stupefies, dimin- ishes the reflex functions of the spinal cord, and causes convulsions, insensibility, and death ; but these cerebral phenomena are not sepa- 456 CEREBRAL EXCITANTS. rable from the reflex effects, on the nervous centers, of the violent gastro-intestinal disturbance. Sometimes dysuria has been caused by- camphor, and, in small doses, owing doubtless to the merely stimulant effects on the circulation, it increases the sexual appetite ; but, in large doses, it is antaphrodisiac. Camphor, after absorption, is eliminated chiefly by the skin and bronchial mucous membrane, hence the breath and sweat of those using this substance smell of it strongly ; but, when much camphor is taken in the solid form, it escapes with the f seces. Therapy. — Camphor enters into the composition of many denti- frices. Camphor is contraindicated in all inflammatory affections of the gastro-intestinal mucous membrane. In hysterical vomiting a few drops of the spirit (two to five), every half -hour or hour, will often give relief. Camphor is an efficient remedy in summer diarrhoea. It is usually combined with opium : I£ Spirit, camphorae, tinct. opii, aa f ss. M. Sig. : Ten to thirty drops every two, three, or four hours. I£ Aqua camphoraa, § iij ; tinct. lavendulse comp., J j ; tinct. opii, 3 j — 3 ij. M. Sig. : A tablespoonful every hour or two. This is an ex- cellent formula, omitting the opium, for flatulence, especially hysterical flatulence and the flatulent colic which so often occurs during the cli- macteric period. For the preliminary diarrhoea of Asiatic cholera camphor is largely used, and with very obvious benefit. A drop or two of the saturated tincture (Rubini's), or five to ten drops of the spirit, may be given with a little laudanum every half-hour or hour. Oppolzer gave the ethereal tincture with opium : ^ Camphorae, § j ; etheris, ? vij ; tinct. opii, 3 j. M. Sig.: Twenty to forty drops, as necessary. Camphor, which is very serviceable in the summer diar- rhoea of children, may be given to these little subjects in milk, in which it is soluble in the proportion of one drachm to four ounces. Spirits of camphor, in the form of vapor, is a useful inhalation in the incipiency of acute catarrh. Dr. Beard speaks in very enthusias- tic terms of a camphor preparation which he has called " cold powder." This formula is as follows : " Camphor, five parts. Dissolve in ether to the consistence of cream. Then add carbonate of ammonium four parts, opium-powder one part." The dose of this ranges from three to ten grains. Dr. Beard finds this combination of " great value in breaking up colds, when taken in time, and in modifying their force when taken late." Camphor was formerly much used in the treatment of asthma, but, at present, more efficient remedies have taken its place. The mono- bromide of camphor has proved decidedly beneficial in whooping-cough. Five grains, suspended in mucilage and sirup of tolu, may be given to a child three or four times a day. It is most serviceable in the spas- modic stage, but will do good at any period. CAMPHOR. 457 Camphor will allay cough and promote . expectoration, hence its utility in chronic bronchitis, in capillary bronchitis when stimulants are needed, and in emphysema. In the so-called typhoid pneumonia camphor is serviceable as a stimulant, in small and frequently-repeated doses, to sustain the powers of life during the period of deferves- cence. In typhus and typhoid fevers, and in the exanthemata generally, camphor is used to accomplish two objects — to quiet delirium, subsul- tus, or restlessness, and to overcome the cardiac depression. When very active interference is unnecessary the following can be used : ^ Aqua camphorse, liq. ammonias acetatis, aa § ij- M. Sig. : A table- spoonful every two hours. Attacks of nervousness and hysteria are relieved by camphor-julep, i. e., camphor rubbed up with mucilage. Some cases of delirium tre- mens are benefited by camphor, but it is impossible to indicate the special condition requiring it. Maniacal excitement, melancholia, and erotomania, have also been relieved by this agent, but a great uncer- tainty exists as to the indications for its employment. Large doses are necessary in these affections, and they should at first be tentative, for it is not possible in the present state of our knowledge to predict the results of any given trial. On the whole, but little dependence is to be placed on camphor ; besides, more certain and effective remedies are now available for the treatment of these maladies. There appears to be a satisfactory clinical experience as respects the use of camphor to allay sexual excitement. Large doses (from ten to twenty grains) diminish the venereal appetite and the vigor of the erections ; hence the use of camphor in priapism, satyriasis, nympho- mania, chordee, etc. The following is a formula of Ricord : I£ Caui- phorse, lactucarii, aa 3 j. M. Ft. pil. no. xxx. Sig. : One or tico pills, or more, as necessary. For nocturnal seminal losses, with weakness and relaxation of the genitalia, the following formula is useful : ^ Ergotine (aq. ex., Squibb's), 3ij ; camphora?, 3 j- M. Ft.pil.no. xxx. Sig. : Two at bed-hour. A full dose of camphor will often ar- rest the strangury produced by blisters. Considerable testimony has been collected showing the value of camphor as a remedy in senile gangrene, and in hospital gangrene. Five to fifteen grains every four hours may be given in an emulsion, and powdered camphor may be applied freely to the sloughing surface. A clyster of camphor is an effective remedy against ascarides. Camphor was a favorite remedy with Dewees for dysmenorrhcea. He gave ten grains in a mixture with mucilage and cinnamon-water, and repeated the dose in an hour or two if necessary. For after-pains, camphor (ten grains), in a mixture with a little morphine (one eighth of a grain), is an effective remedy. External Uses. — A cataplasm of camphor, morphine, and flax- 458 CEREBRAL EXCITANTS. seed, applied to the cheek, will relieve toothache. Camphorated oil is a mild counter-irritant, which is a useful external application for the relief of internal inflammations. The solution of camphor in ether has been applied locally with benefit in erysipelas. Myalgia, lumbago, and neuralgia of superficial nerves, may sometimes be relieved by frictions with camphorated oil or soap-liniment. Powdered camphor, freely sprinkled over the surface, is one of the means resorted to, and sometimes with success, to prevent pitting of the face from variola.

(Asa- foetida, galbanum, and myrrh.) Dose, 1 — 4 pills. Composition. — About one half of the gross constituents of asafoetida consists of resin. This is not wholly soluble in chloroform or ether. It contains a peculiar acid (ferulaic acid). Asafoetida also contains a sulphureted and phosphureted volatile oil, in the proportion of from three to five per cent. This oil is at first neutral, but becomes acid by exposure to the air, and evolves sulphureted hydrogen. It possesses in a high degree the disagreeable odor of the drug. Asafoetida also contains malic acid, and acetic, formic, and vale- rianic acids are products of the watery distillation. There is sufficient gum present also to form an emulsion with water. Antagonists and Incompatibles. — Acids, neutral salts, cold, and arterial sedatives, oppose the action of asafoetida. ASAFCETIDA. 459 Synergists. — The gum-resins, the balsams, and the aromatics, es- sential oils containing sulphur and phosphorus, and alcohol and ether, promote the physiological and therapeutical activity of asafcetida. Physiological Actions. — Asafcetida possesses an extremely char- acteristic odor, and a pungent, rather hot, and faintly acrid taste. It excites by its presence in the fauces an increased flow of saliva. It stimulates secretion from the gastro-intestinal mucous membrane, pro- motes the appetite, improves digestion, and increases peristalsis. The faeces are somewhat softer, and are very offensive from the presence in them of sulphur and phosphorus compounds, resulting from the de- composition of the essential oil. In large quantity asafcetida causes nausea, vomiting, and purging. The active principle (the essential oil) undoubtedly slowly diffuses into the blood, for the odor of it is detectable in the sweat and breath. Increased action of the heart, a higher temperature of the surface (subjectively, at least), more or less diaphoresis, and diuresis, have been observed to follow its medicinal administration. It acts as a gentle stimulant to the brain, induces a feeling of well-being, increases the flow of ideas, and causes, as the author has observed in one case, certainly, sufficient exhilaration of a pleasant kind to be regarded as an intoxicant. Asafcetida is eliminated by the skin, intestinal and bronchial mu- cous membrane, and in small part by the kidneys. The functions, of all these organs are increased in activity by the local stimulant effect. Partly due to the general rise of arterial pressure which it produces, partly to its local action in the process of elimination, and partly to its phosphorus compounds, asafcetida increases the menstrual flux, and, in both sexes, the venereal appetite. Therapy. — Asafcetida is used in the country of its habitat as a condiment. A little — very little — rubbed on the gridiron, improves the flavor of beefsteak. If it were not for its intolerable odor, and for the horrible eructations which follow its use, even when disguised in a sugar-coated pill, it would be much employed as a stomachic tonic in atonic dyspepsia, accompanied by torpor of the intestines. For the flatulent colic of infants no remedy is better than mistura asafoetidm, which may be given in teaspoonful doses. It is especially in the flatu- lence of hysteria and hypochondriasis that this remedy is serviceable. It expels the flatus, promotes intestinal secretion and digestion, and relaxes the bowels. In this way the mind is relieved, but the action of asafcetida extends beyond this improvement in the state of the chylopoictic viscera — it induces a condition of mental cheerfulness which takes the place of the abnormal mobility of hysteria, and of the gloom of hypochondriasis. The official pill of aloes and asafcetida is an excellent combination for the relief of constipation, when associated with amenorrhoea. It is adapted, of course, to those cases in which there is a condition of 460 CEREBRAL EXCITANTS. anaemia rather than of plethora, and in which there exists a state of torpor of the ovaries, as well as of the intestinal canal. These condi- tions existing, the combined pill of aloes and asafoetida is indicated whether hysteria be present or not. The chronic scaly eruptions, chronic eczema, etc., especially when the skin is dry and harsh, are much improved by the persistent use of asafoetida. Bronchorrhwa, bronchitis after the acute symptoms have subsided, the cough mamtained by habit which may succeed the whooping-cough, and the sympathetic cough of mothers whose children are experiencing whooping-cough, are greatly benefited by asafoetida. I£ Mist, asafoeti- dse, | iv ; ammonii muriat., 3 j. M. Sig. : A tablespoonful as neces- sary. Asafoetida, which was formerly much prescribed in asthma, ivhoop- ing-cough, and other neuroses of the respiratory organs, has been sup- planted by more efficient remedies. The disagreeable odor of asafoetida, which is a bar to its employ- ment in many of the diseases to the treatment of which it is very well suited, is not an objection to its use in hysteria, hypochondriasis, and epilepsy. The moral effect of its repulsive odor is not without influence in the psychic realm. But the effect of asafoetida is not simply on the imagination of the patient ; it has constituents of very positive quality, which impress the brain. Hence the utility of asafoetida to arrest the hysterical paroxysm, and to relieve the numerous maladies in which the hysterical constitution disports itself. The remarks already made in regard to the action of asafoetida on the digestive functions in hypo- chondriacal subjects, render it unnecessary to speak more at length on the use of this remedy in hypochoyidriasis. Asafoetida is no longer employed in the treatment of epilepsy, except in the so-called hystero- epilepsy. The convulsions of childhood, from reflex irritation, are sometimes relieved by this remedy, but it is entirely without utility in convulsions arising from renal or cerebral disease.

It has the odor of the drug. Ammoniac also contains gum and resin, the latter in the pro- portion of about seventy per cent. VALERIAN. 461 Antagonists, Ixcompatibles, and Synekgists, same as for asa- foetida. Physiological Actions. — The effects of ammoniac are similar to those of asafoetida, but it is much less active, owing to the fact, chiefly, that its volatile oil does not contain sulphur and phosphorus com- pounds. Therapy. — Ammoniac may be used for the same purposes as asa- foetida, but it is much less efficient than the latter. At present its use is almost entirely restricted to chronic bronchial affections, in which the mistura is prescribed usually with the carbonate or chloride of ammo- nium. Ammoniac-plaster is sometimes used as a discutient to indo- lent glandular and inflammatory swellings. Authorities referred to : Fluckiger and Hanbury. Pharmacographia. Gubler, Dr. A.

It deliquesces in a moist air, but effloresces in a dry one, and is very soluble in water and in alcohol. It is decomposed by potassa, with evolution of ammonia, and by the mineral acids with separation of valerianic acid, which rises to the surface in the form of oil. Oleum Valerianae. — Oil of valerian. Dose, tt|, ij — tti iv. Composition. — Valerian contains from one to two per cent of an essential oil, which, if distilled from the perfectly fresh plant, has but little odor. In the process of drying of the root, or on exposure to the air of the oil distilled from fresh roots, valerianic acid is formed. As obtained from the dried root, the oil of valerian consists of valeri- anic acid, a camphor, valerene, and valerol. An acid strongly resembling valerianic is obtained by the oxida- 462 CEREBRAL EXCITANTS. tion of amylic alcohol ; but the two acids are not identical. The valerianic acid of pharmacy is, however, obtained in this way, and the various valerianates are products of the combination of the acid formed from amylic alcohol with bases. Antagonists and Incompatibles. — Quinine, digitalis, ergot, and remedies acting similarly, antagonize the actions of valerian. Synergists. — All the agents of this group, opium, alcohol, ether, etc., increase the action of valerian. Physiological Actions. — Valerian and its preparations have a hot, pungent taste, and a peculiar and disagreeable odor. A sensation of warmth at the epigastrium follows when it is taken into the stom- ach. In large doses, nausea, hiccough, eructations of the drug, vomit- ing, and diarrhoea, may be produced. In small doses no appreciable physiological effects are observed ; but in considerable doses the action of the heart is increased, the temperature of the surface rises, and dia- phoresis occurs. As respects the nervous system, headache, vertigo, exhilaration of mind, spectral illusions, hallucinations, have, it is said, been produced by valerian ; but these results are by no means constant phenomena. According to Von Grisar (Kohler), oil of valerian re- duces the reflex excitability, motility, and sensibility, and antagonizes the tetanizing action of brucine. The odorous principle — valerianic acid — appears in the sweat, breath, and also the urine. Therapy. — The flatulence of the hysterical and hypochondriacal is quickly relieved by the tincture or fluid extract of valerian. It sometimes happens that a mild attack of spasmodic asthma may be relieved by valerian, but this by no means efficient remedy quickly loses its effect. Whooping-cough, laryngismus stridulus, and other neuroses of the respiratory organs, may be occasionally modified by this agent ; but it is by no means equal to many other remedies now available. The chief therapeutic use of valerian is in the treatment of nerv- ousness, hysteria, and hysterical disorders generally. There can be no difference of opinion as to its great value in these cases ; but as re- spects epilepsy, chorea, paralysis agitans, etc., in which it was for- merly used, it must suffice to say that it is now never prescribed. XJnder the impression that the physiological and therapeutical ac- tivity of valerian depends on valerianic acid, various valerianates have been introduced into practice. The only one which requires notice here is the valerianate of ammonia, which in the form of elixir is fre- quently prescribed in hysterical affections. Fluid extract of valerian has been used with advantage in diabetes insipidus and also in saccha- rine diabetes, but the results are not permanent. It diminishes the amount of urinary water in both, and lessens the excretion of sugar in the latter, but these effects continue only while the remedy is given.

Cannabis Indica. — Indian cannabis. The flowering tops of the female plant of Cannabis sativa Linne* (Nat. Ord. TJrticaceoe, Canna- binece), grown in the East Indies. (U. S. P.)

Extractum Cannabis Indicm Fluidum. — Extract of cannabis In- dica. Dose, iu ij — 3 ss. Tinctura Cannabis Indicm. — Tincture of cannabis Indica. Dose, m v— 3 j. Composition. — The physiological activity of hemp is influenced largely by soil and climate ; for, although in botanical characters In- dian and American hemp are identical, the Indian hemp possesses de-' cidedly more narcotic power. Indeed, until recently, it was supposed that American hemp was devoid of the peculiar properties possessed by the Indian ; but it has been shown that American hemp does really have effects similar in kind to, but much less in degree than, those caused by the Indian. The most important constituent of hemp is a peculiar resin, canna- bin, which possesses the active powers of the plant. By distillation of the leaves and stems, a peculiar volatile oil is obtained ; and this is divisible into cannabene, a very light hydrocarbon, and hydride of cannabene, a solid crystalline substance. An impure resin, collected in an imperfect and crude way from the leaves and stems, is known as charas, or churrus. Bhang consists of the dried leaves and stalks made into a confection with preserved fruits and aromatics, and, in this form, constitutes the well-known hashish. Gunjah is the female flowering plant, dried, from which the resin has not been extracted. No arbitrary rules for the dose can be laid down. In beginning the use of any newly-made preparation, it is safer to commence with the minimum dose. Having, by gradually increasing the quantity, ascertained the physiological activity of that particular specimen, it may then be pushed according to the necessities of the case. Antagonists and Incompatibles. — The caustic alkalies, the acids, strychnine, and induction electricity, oppose the actions of hemp. In cases of poisoning, the stomach should be evacuated, and symptoms be combated as they arise. Strychnine may be injected hypodermatical- 464 CEREBRAL EXCITANTS. ly, and the respiration be maintained by faradization of the respiratory muscles. As, however, hemp possesses but feeble toxic power, cases of acute poisoning have never been reported. Synergists. — Alcohol, ether, nitrous oxide, the mydriatics — bella- donna, hyoscyamus, etc. — opium, and the cerebral stimulants general- ly, promote the actions of hemp. Physiological Actions. — The resin of hemp is a soft solid ; is soluble in alcohol and in ether, in the fixed and volatile oils, and in the fats. It has a balsamic taste, but is bitter and acrid. It promotes the appetite and the digestion somewhat. The most important actions are those referable to the nervous system. There is a distinction to be made between the effects on the nervous system of the inhalation of the fumes of hashish and those effects which follow the stomach administration. Inattention to this point has, probably, given rise to most of the confusion regarding the physiological actions of this rem- edy. When inhaled it produces a singular muscular erythism and agi- tation, a great desire for muscular activity and motion, an entire absence of the sense of fatigue ; but these sensations are followed by exhaus- tion, even by syncope. Hallucinations occur, but they are not usually agreeable ; they are often painful, and are replaced by stupor. By the stomach, and in moderate doses, hashish is an excitant of the nervous system, increasing intellectual and motor activity. In large doses, it lowers the tactile sense and the sense of pain — in other words, it is analgesic and anaesthetic — and it induces a cataleptic state, in which the muscles maintain any position in which they may be placed. The mental intoxication is ordinarily of an agreeable kind ; the ideas flow more easily, are highly pleasurable, and are usually ac- companied by bursts of gay laughter. Not unfrequently the excite- ment takes the form of a furious delirium, in which acts of violence are committed — whence the name " haschaschins," or assassins, applied to the unfortunate hashish-eater who, under the influence of the drug, commits murder. It has been maintained, and probably rightly enough, that the form which the delirium takes represents the mental and moral condition of the individual in his normal state : those who are amiable and gay become more so under the influence of hashish ; and those possessed of evil and malignant dispositions enact deeds of violence. Under the influence of hashish the knowledge of time is lost ; such are the number and variety of the images which occupy the mind, that a few minutes appear to be hours, days, or even years. After the effects of the drug have passed off, the hashish-eater is usually uncon- scious of the events that have transpired. Sleep or coma, according to the dose, ends the effects of the drug. Dilatation of the pupil, and disorders of vision, which contribute to the hallucinations by the distortion of external objects, are produced by hemp. Aphrodisiac effects are said to follow the use of hashish ; CANNABIS INDICA. 465 but impotence, which is common in hashish-eaters, doubtless results from the repeated over-stimulation of the sexual organs. It is not known by what organs, or in what form, hashish is elimi- nated. The effects of a large dose are not entirely expended in twenty- four hours, and those who have taken it by way of experiment have suffered vertigo, headache, and other cerebral symptoms, for some time subsequently. It does not increase any of the secretions, except it may be the urinary, somewhat ; and it does not stimulate into increased activity any organs except the cerebro-spinal and the sexual. The sleep or stupor which it produces, and which comes on after the stage of excitement, is not followed by after nausea and depression, as in the case of opium. Therapy. — The extract of cannabis Indica enters into the compo- sition of chlorodyne, a nostrum which has had a great reputation as an anodyne and hypnotic. In cholera morbus and diarrhoea this remedy has been used successfully, but we now possess more efficient ones. Before the days of anaesthesia, and in very remote times, the fumes of hashish were employed to stupefy and to render painless surgical operations. It was also employed to relieve pain, and as a substitute for opium in neuralgia, and as an hypnotic. In migraine it has been used with decided success by Seguin, Williams, and others. Good re- sults have been obtained from it in epilepsy by Sinkler and others, and it deserves further consideration in this disease. In chorea, and in delirium tremens, it is strongly urged by De Cavaillon, and in senile trembling and paralysis agitans it has afforded relief. About one half of the cases of tetanus, for which hemp was much prescribed a few years ago, got well under its use ; but more accurate knowledge of the natural history of this disease has shown that many cases tend to recovery without the aid of medicines. It is well established that hemp has the power to promote uterine contractions. It can not initiate them, but increases their energy when action has begun. It may be given with ergot. In consequence of this power which it possesses to affect the muscular tissue of organic life, hemp is used successfully in the treatment of menorrhagia. It is said to be especially useful in that form of menorrhagia which occurs at the climacteric period (Churchill). It has, more recently, been shown to possess the power to arrest hemorrhage from any point, but it is chiefly in menorrhagia that so much good is accomplished. There can be no doubt that cannabis Indica is a useful remedy in cases of impotence. It need hardly be stated that it is adapted to the functional disorder. It may be advantageously combined with ergot and nux vomica in this malady ; for example : fy Ext. cannabis Indi- cse, gr. x ; ergotin (aq. ex.), 3ij ; ext. nucis vom., gr. x. M. Ft. pil. no. xx.

Preparation. — Extr actum Erythroxyli Fluidum. — Fluid extract of erythroxylon. Dose, 3 ss — 3 ij. Composition. — The effects of coca, or cuca, depend on the pres- ence of a peculiar alkaloid — cocaine. It contains also an aromatic oil which gives it the special aroma and taste, and it possesses consider- able astringency, due to the presence of a tannic acid. The odor, taste, and appearance of the infusion are comparable to those of tea. Cocaine has decided basic properties, and combines with acids to form salts. It crystallizes in prisms in the smaller rhombic system (Huse- mann), which, when pure, are transparent and colorless. It is very slightly soluble in water and in alcohol, but dissolves freely in ether. It has a bitter taste, and the salts are more bitter than the alkaloid itself. Antagonists and Incompatibles. — The actions of coca are op- posed by all those agents which increase waste. The infusion and fluid extract are incompatible with the metallic salts. Muriatic acid splits cocaine into benzoic acid and an alkaloid — ecgonine ; hence the mineral acids should not be prescribed with the infusion and fluid ex- tract. Synergists. — The agents promoting constructive metamorphosis, caffeine, the cerebral stimulants, and the narcotics generally, increase the effects of coca. Physiological Actions. — The historical notes of Sir R. Christi- son show that the peculiar properties of cuca-leaves have long been known to the inhabitants of Peru. The leaves have a strong, tea-like odor, and the infusion resembles ordinary tea in taste. The volatile oil and the active principle are readily diffusible, and enter the blood with facility. A momentary depression of the pulse and diminution of the blood-pressure take place, but these effects are quickly over- come, and a considerable increase in the action of the heart and of the blood-pressure follows (Ott). A feeling of contentment and of well- being takes possession of the mind, the sense of fatigue is removed, drowsiness is experienced for a brief period, but it is soon succeeded by wakefulness, and increased mental activity. It has long been known to the mountaineers of the Peruvian Andes that chewing cuca- CAFFEIXE. 467 leaves increases the respiratory power, and removes, or lessens, the sense of fatigue. The celebrated pedestrian, Weston, having learned this fact, was detected in the use of cuca during one of his extraordi- nary feats in London (Thompson). As respects the action of cocaine on the nervous system, it has been demonstrated that it diminishes the excitability of the motor nerves, and impairs the power of voluntary co-ordination. Its influence on the sensory nerves depends on the quantity of the drug ingested ; a small quantity increases the excitability of the sensory nerves, whereas a large quantity causes paralysis (Ott). It is not known whether or not the paralysis is the result of over-stimulation and an exhaustion of the sensibility. The posterior columns of the spinal cord are chiefly affected. The paralysis of the heart which ensues from a large quan- tity seems to be due to an action on the intra-muscular ganglia of this organ. It first excites, then paralyzes, the respiratory center. The most interesting question connected with the action of cuca is its influence over the metamorphosis of tissue. It certainly lessens urea-elimination. As is the case with coffee and tea, cuca acts as an indirect nutrient, by checking waste, and hence a less amount of food is found necessary to maintain the bodily functions. It is probable that some of the constituents of cuca are utilized in the economy as food, and that the retardation of tissue-waste is not the sole reason why work may be done by its use which can not be done by the same person without it. Therapy. — Although cuca possesses valuable powers as a restora- tive, but little use has been made of it, except by the French. It will, no doubt, be found useful in phthisis, and wasting diseases generally, and in convalescence from acute maladies. It is a valuable remedy in the nervous form of sick-headache, migraine. It has been used with distinct advantage in the depression caused by the withdrawal of opium, in the treatment of the opium-habit, and in functional impo- tence, due to a lowered condition of the general health.

It has a bitter and disagreeable taste, and is soluble in water, alcohol, and ether. As regards composition, caffeine is re- markable for the quantity of nitrogen which it contains, surpassing in this respect almost all the alkaloids. In the coffee-bean, caffeine ex- ists in combination with a peculiar acid, caffeic, and with caffeo-tannic acid. Antagonists and Incompatibles. — Tannic acid, iodide of potas- sium, and the salts of mercury, precipitate caffeine from its solution in water. Physiologically, it is antagonized by opium (Bennett). Synergists. — The actions of caffeine are promoted by the agents of this group, and by the mydriatics. Physiological Actions. — -The effects of coffee as a beverage have been sufficiently discussed elsewhere. Caffeine, in small medicinal doses, promotes appetite, increases the digestive power by stimulation of the gastric glands, and relaxes the bowels slightly. On the heart it exerts at first a decided stimulant action, and raises the arterial tension ; but these effects are succeeded by weakened cardiac movements and diminished blood-pressure, the cardiac muscle and its contained ganglia being both probably para- lyzed by it. Respiration ceases before the heart stops in animals poi- soned by caffeine (Bennett). As regards the cerebral effects, it may be stated that, at first, drowsiness occurs ; but this is soon followed by wakefulness, excite- ment, muscular trembling, confusion of mind, hallucinations, and delirium. The cerebral effects terminate in deep sopor, but this is probably the result of exhaustion. Rise of temperature, convulsions, general paralysis, occur when toxic doses are administered to animals ; but the temperature declines when paralysis supervenes (Leven, Schmiedeberg, Bennett, and others). Therapy. — Caffeine is a useful stomachic tonic. In convalescence from acute maladies, it is in a high degree serviceable, given to pro- mote the constructive metamorphosis. Chronic catarrh of the stomach, with occasional attacks of migraine, is a combination of maladies in which caffeine is especially useful. Paullinia, or cuca, may be used instead. In the diarrhoea of phthisis, in ordinary atonic diarrhoea, in cholera infantum, and in cholera morbus, produced by agencies affecting the nervous system, the remedies of this group, especially caffeine, are often extremely useful. When the vital powers are depressed, and when there is at the same time an abnormal excretion of urea — a condition of things which exists in incipient phthisis, associated with indigestion — caffeine, cuca, and paullinia are in a high degree service- GUARANA. 469 able. They increase the appetite and the digestive power, and dimin- ish tissue-waste. Black coffee, or caffeine, increases the action of the heart and raises the arterial tension, and is therefore useful when the circulation is de- pressed from various causes. An important use of caffeine, at present, is in the treatment of headache. It is adapted especially to the relief of migraine, the so-called nervous headache, accompanied with or without stomach- derangement. In this disorder we may administer a grain of caffeine every half -hour, until the headache is relieved ; or the citrate of caf- feine may be given in an effervescent draught. A very elegant prep- aration is the granular, effervescent citrate of caffeine. Caffeine has proved very useful in cardiac dropsy / and in renal dropsy in inverse ratio to the amount of damage suffered by the kid- neys, for, as Brackenridge has shown, this remedy does not increase the flow of urine when the renal epithelium is destroyed. It may be used with advantage in ascites when any diuretic will prove service- able. It has, within the past two years, been much employed by the French therapeutists, in place of digitalis, in the treatment of certain cardiac affections. According to Huchard, caffeine acts more rapidly than digitalis, causing free diuresis in twenty-four hours. It slows the pulse and raises the arterial tension, thus effecting a better distri- bution of the blood. To bring about these desirable effects, Huchard rapidly increases the dose, so that on the third day he gives a gramme (15 J grs.) hypodermatically. The action of opium is antagonized by caffeine ; hence this agent is employed in opium narcosis, and in some cases with success. It may be injected hypodermatically when the patient is unable to swal- low ; but it can not take the place of atropine. In hypochondriasis, and in simple melancholy, caffeine has been used with advantage. It may be given to relieve the drowsiness which in so many persons comes on after a late dinner. It helps to dissipate the stupor of urcemia. Cases of cervico-brachial neuralgia have been relieved by the hypo- dermatic injection of caffeine. Guarana. — A dried paste, prepared from the crushed or ground seeds of Paullinia sorbilis Martius (Nat. Ord. Sapindacece). (U. S. P.) Extr actum Guaranm Fluidum. — Fluid extract of guarana. Dose, m x— 3 ij. Composition. — It contains a principle which has been entitled gua- ranine, and which subsequent researches have proved to be identical with caffeine. Actions and Uses. — The physiological effects of paullinia are due to its alkaloid, chiefly ; and, as this is the same as caffeine, the ob- 470 CEREBRAL SEDATIVES. servations already made on the latter are equally applicable to the former. The special use of paullinia is in the treatment of sick-headache or migraine. It is adapted to the so-called nervous form of sick- headache, and is less efficient when the attacks are due to stomachal troubles. As it possesses, directly or indirectly, restorative powers, it may be employed to promote constructive metamorphosis. Adminis- tered with this view, it may be given with advantage in the conva- lescence from acute maladies, in incipient phthisis, and in the wasting diseases generally. The most agreeable form in which to administer paullinia is the elixir, but, as this preparation varies according to the taste, honesty, and skill of the apothecary, the physician needs to be assured of its quality before prescribing.

REMEDIES WHICH DIMINISH OR SUSPEND THE FUNCTIONS OF THE CEREBRUM AFTER A PRE- LIMINARY STAGE OF EXCITEMENT. To this group belong the so-called narcotics, the ansesthetics, and some of those usually classed as antispasmodics. They all agree in these respects : their effects are expended, chiefly, on the nervous sys- tem ; they first stimulate the functions of the brain, but this stage of excitement, which may be of shorter or longer duration, is followed by sopor, coma, and complete insensibility. Alcohol. — Alcohol. A liquid composed of 91 per cent by weight (94 per cent by volume) of ethyl alcohol, and 9 per cent by weight (6 per cent by volume) of water. Specific gravity, 0*820 at 60° Fahr. A transparent, colorless, mobile, and volatile liquid of a characteristic, pungent, and agreeable odor, and a burning taste. (IT. S. P.) Alcohol Dilutum. — Diluted alcohol. A liquid composed of 45*5 per cent by weight (53 per cent by volume) of ethyl alcohol, and 54*5 per cent by weight (47 per cent by volume) of water. Specific gravity, ALCOHOL. 471 0-928 at 60° Fahr. Alcohol, 50 parts ; distilled water, 50 parts. (IT. S. P.) Alcohol Amylicum. — Amylic alcohol. Fusel-oil. A peculiar alcohol, obtained from fermented grain or potatoes, by continuing the process of distillation after the ordinary spirit has ceased to come over. An oily, nearly colorless liquid, having a strong, offensive odor, and an acrid, burning taste. Its specific gravity is 0*818, and its boiling-point between 268° and 272°. It is sparingly soluble in water, but unites in all proportions with alcohol and ether. It does not take fire by contact with flame, and, when dropped on paper, does not leave a permanent greasy stain. Exposed to the air in contact with platinum-black, it is slowly oxidized and yields valerianic acid. (U. S. P., 1870.) Spiritus Frumenti. — Whisky. An alcoholic liquid, obtained by the distillation of fermented grain (usually corn, wheat, or rye), and at least two years old. Whisky has an amber color, a distinctive taste and odor, and a specific gravity not above 0*930 nor below 0*917, corresponding ap- proximately with an alcoholic strength of 44 to 50 per cent by weight, or 50 to 58 per cent by volume. Spiritus Vini Gallici. — Brandy. An alcoholic liquid obtained by the distillation of fermented grapes, and at least four years old. Brandy has a pale, amber color, a distinctive taste and odor, and a specific gravity not above 0*941 nor below 0*925, corresponding ap- proximately with an alcoholic strength of 39 to 47 per cent by weight, or 45 to 55 per cent by volume. (U. S. P.) Composition. — A large number of bodies have been classed under the generic term of alcohols. A list of the most important of these is subjoined : Methylic alcohol. CH 4 0. Ethylic Propylic Butylic Amylic Caproic C 2 H 6 or CH 4 + (CH 2 ). C 3 H 8 or CH 4 04-2(CH 2 ). C 4 H 10 or CH 4 + 3(CH 2 ). C 5 H 12 or CH 4 + 4(CH 2 ). C 6 H 14 or CH 4 + 5(Cn 2 ). These alcohols are called " homologous," because they are closely related to each other, and differ by the common multiple CH 2 . Ethylic is the common or ordinary alcohol, and amylic is an impurity existing in certain alcoholic beverages — for example, whisky, in which it oc- curs in consequence of the cupidity of distillers in carrying on the process after all the ethylic alcohol has distilled over. Absolute alco- hol should be entirely free from any odor except its native ethereal odor, and no products but carbonic acid and water should result from its combustion. Whisky is a solution of alcohol in water (48 to 56 per cent), but 472 CEREBRAL SEDATIVES. contains various odorous principles and ethers which impart to it its peculiar physical properties. The best specimens, doubtless, contain traces of f usel-oil, and acetic, butyric, and sometimes valerianic acids are present in it. The reactions of these acids with the alcohol result in the formation of various ethers, and hence old whisky is more fra- grant, and therefore more highly prized, than the recent product of the still. Brandy is also a solution of alcohol in water (48 to 56 per cent). It has a wine-like odor, and a hot, astringent taste. It contains a volatile oil, an ether peculiar to wines (cenanthic ether), coloring-mat- ters, tannic acid, aldehyde, and acetic ether. The color is usually fac- titious : in pale brandy, the color is derived from the cask ; in dark brandy, from caramel. Brandy is made artificially from high-wines by the addition of an ether (cognac, acetic or nitric), of coloring- matter (burnt sugar), and an astringent to give it the necessary rough- ness of taste (logwood, catechu, etc.). Physiological Actions. — Alcohol in prolonged contact with the skin, evaporation being prevented, excites a sense of heat and super- ficial inflammation. It coagulates albumen and hardens the animal textures. The epithelium of the mouth is corrugated by it — a result due to the abstraction of water and condensation of the albumen. In the stomach alcohol causes a sense of warmth, which diffuses over the abdomen, and is quickly followed by a general glow of the body. In moderate quantity it induces a superficial congestion of the mucous membrane — a dilatation of the arterioles — and this increased blood- supply enables the mucous follicles and the gastric glands to produce a more abundant secretion. The increased formation of the stomach- juices is doubtless somewhat determined by the stimulation of the mouths of the glands, in accordance with a well-known physiological law. The excitation of the gastric mucous membrane, when habitual, results in important changes ; a gastric catarrh is established — for the mucous follicles, under the influence of repeated stimulation, pour forth a pathological secretion. The gastric glands at first simply pro- duce an increased amount of gastric juice, but abnormal stimulation results in pathological changes in this secretion. The increased blood- supply to the mucous membrane sets up an irritation of the connective tissue, which undergoes hyperplasia ; the proper secreting structure is encroached upon, and the glands suffer atrophic changes which re- sult in still more important modifications of the gastric juice. Alco- hol also affects directly the constitution of the gastric juice by precipi- tating the pepsin from its solution and by arresting the activity of this ferment. In small doses, not too frequently repeated, alcohol increases the digestive power by stimulating the flow of blood and soliciting a greater supply of the stomach-juices. Large doses impair digestion ALCOHOL. 473 directly by precipitating the pepsin, an albuminoid ferment. That a small quantity does not produce the same results in a comparative de- gree, is simply due to the fact that it is too far diluted, by the quan- tity of fluid present in the stomach, to act on the pepsin. The structural alterations induced by the habitual use of alcohol, and the action of this agent on the pepsin, seriously impair the diges- tive power. Hence it is that those who are habitual consumers of alcoholic fluids suffer from disorders of digestion — gastric catarrh. The abnormal mucus which is elaborated in great quantity, acts the part of a ferment, and the starchy, saccharine, and fatty elements of the food undergo the acetic, lactic, and butyric fermentations. Acidity, heart- burn, pyrosis, regurgitation of food, and a peculiar retching in the morning (morning vomiting of drunkards), are produced. As alcohol is a very diffusible substance, it enters the blood with great facility, and probably almost all of that taken into the stomach passes into the blood from this organ, and does not reach the small intestine. The liver is consequently the first organ, after the stomach, to be influenced by the ingested alcohol. The blood of the portal vein, rendered more highly stimulating by the presence of alcohol, in- creases for the time being the functional activity of the liver-cells, and, as is the case with the stomach, a more abundant glandular secre- tion follows. Frequent stimulation and consequent over-action result in impairment or loss of the proper function of the part, as is the uni- versal law. The hepatic cells, over-stimulated, produce an imperfect product ; they are affected by fatty and atrophic changes, and shrink in size ; and the connective tissue of the liver undergoes hyperplasia. The first result of the structural alterations is an increase in the size of the organ ; but with the shrinking of the hepatic cells, and the con- traction of the newly-formed connective tissue, the liver becomes smaller, nodulated, and hardened. To this change the term cirrhosis has been applied. It is essentially a slowly-developing and chronic malady, and long indulgence in alcoholic liquids is necessary to its pro- duction. In small doses, alcohol increases the action of the heart and the cutaneous circulation ; a slight general rise of temperature is observed ; and all of the functions are, for the time being, more energetically performed. If a considerable dose be taken, the phenomena of exhila- ration, of excitement, of slight intoxication ensue. A still larger quan- tity causes loss of muscular power, impaired co-ordination of voluntary movements, and rambling incoherence. When a toxic dose is taken, the stage of excitement is of short duration ; profound insensibility, with stertorous breathing and complete muscular resolution, quickly follow. As respects the action of alcohol on the nervous system, it is ob- vious that its first effect is to increase the functional activity of the brain ; the ideas flow more easily, the senses are more acute, the muscu- 474 CEREBRAL SEDATIVES. lar movements are more active. These effects are coincident with the increased action of the heart, the slight rise of temperature, and the greater activity of the functions of the organism in general. With the increased action of the alcohol on the cerebrum the excitement becomes disorderly, the ideas incoherent and rambling, the muscular movements uncontrolled and inco-ordinate (over-stimulation of the cells of the gray matter). With an excessive quantity, the functions of the cerebrum are suspended, and complete unconsciousness ensues ; the reflex movements cease ; the functions of organic life are performed feebly ; and, by an extension of the toxic influence to the centers pre- siding over these movements, respiration and circulation are finally arrested. That these effects on the intra-cranial organs are due to the direct action of the alcohol has been shown. Alcohol has been discovered in the fluid contained in the ventricles, and has been distilled from the cerebral matter ; and Hammond has demonstrated that it has a special affinity for nervous matter, being found in the cerebro-spinal axis and in the nerves, in greater quantity than in other tissues of the body. As a result of the direct contact, chiefly, but in part also from the va- riations in the intra-cranial blood-current, important structural altera- tions are gradually wrought in the cerebral matter. The cells of the gray matter become more or less fatty and shrunken, the neuroglia undergoes hyperplasia, shrinking and condensation of the whole cere- brum ensue (sclerosis), and the cerebro-spinal fluid relatively increases. The objective evidences of these pathological changes are seen in the impaired mental power, the muscular trembling, the shambling gait, of the drunkard. In some subjects from sudden excess of a periodical kind, in others from a failure of the stomach to dispose, not only of aliment, but of the accustomed stimulus, a peculiar morbid state, known as delirium tremens, is produced. Peculiarity of the nervous system — idiosyncra- sy — is an important factor in the causation of this condition, and probably also the use of alcoholic beverages rich in fusel-oil — for Rich- ardson has shown, and the author has repeatedly confirmed the obser- vation, that amylic alcohol causes tremors and muscular twitching " identical with the tremors observed in the human subject during the alcoholic disease known as delirium tremens." The long-continued action of alcohol on the nervous system pro- duces other disorders besides delirium tremens. Hemi-anaesthesia, epilepsy, paraplegia, amaurosis, etc., have been observed to result from alcoholic excess, and mental alienation, as the asylum statistics prove, lias in the same agent its most influential cause. It is necessary now to consider what becomes of the alcohol after its introduction into the human body, and the influence which it exerts, if any, in the metamorphosis of tissue. The results of experiment on ALCOHOL. 475 these points have been remarkably contradictory ; and the questions involved are by no means settled. It would require a volume to make a satisfactory analysis of the various memoirs and papers which have been published on the actions of alcohol. The author, therefore, merely presents the conclusions to which he himself has come, after a careful consideration of all the more important contributions to the literature of the subject. A small quantity of alcohol, in a subject not accustomed to its use, causes, as has been already stated, increased activity in all the bodily functions, and slight elevation of temperature. Habit, as is the case with a great many drugs, modifies in a remarkable manner the physio- logical activity of alcohol, and hence these results are not perceived in the habitual consumers of this substance. Considerable doses of alco- hol cause a decline in the temperature of the body, which is even more marked in pyrexia than in the normal state. As respects this effect, the influence of habit is equally great, for in old topers a decline in temperature does not follow the use of alcohol in doses short of lethal. In animals the reduction of the body-heat is more marked than in man. To what cause is the decline in temperature, produced by alco- hol, attributable ? This is, doubtless, referable to the diminished rate of tissue metamorphosis — for it has been ascertained that the excretion both of urea and of carbonic acid is lessened by alcohol. The combus- tion of the nitrogen and carbon foods is, therefore, retarded. This action is represented, objectively, by an increase in the body- weight and the embonpoint of those who take stimulants moderately. The disposition of alcohol in the organism is a subject which has gone through several revolutions of opinion. At present the weight of authority and the deductions of experiment are in favor of that view which maintains that, within certain limits (one ounce to one and a half ounce of absolute alcohol to a healthy man), alcohol is oxidized and destroyed in the organism, and yields up force which is applied as nervous, muscular, and gland force. The amount of alcohol ingested, in excess of this oxidizing power of the organism, is eliminated as alco- hql by the various channels of excretion — by the lungs, skin, kidneys, etc. As alcohol checks tissue metamorphosis, and thus diminishes the evolution of heat and force, it might be expected that the products of its own oxidation would supply the deficiency, but this is not the case. Alcohol is a useful food in the small quantity which increases but does not impair digestion, which quickens the circulation and gland secretion but does not over-stimulate, and which is within the limit of the power of the organism to dispose of by the oxidation processes. This amount has been pretty accurately shown, as stated above, to be one ounce to one ounce and a half of absolute alcohol for a healthy adult in twenty -four hours. All excess is injurious. North -pole voyages, military expeditions (experiences in India and the Ashantee 476 CEREBRAL SEDATIVES. march), and the diminished power of resistance to cold shown by- drunkards, have conclusively demonstrated that alcohol does not sup- ply the place of other foods ; and that those habituated to its use, damaged as they are in their vital organs, do not possess the same endurance of fatigue and the same power of resistance to external morbific influences as do the healthy. Furthermore, clinical expe- rience has amply proved that topers do not bear chloroform well, that they succumb more quickly to injuries and surgical operations, and that they possess much less power of resistance than the temperate to the inroads of acute diseases. While these facts rest upon the soundest basis, it is equally true that alcohol is, within certain limits, a food, and that the organism may subsist, for a variable period, on it exclusively. It is an important clinical fact that the physiological effects of alco- hol differ in different conditions of the system. In convalescence from acute diseases, in the sudden depression of the powers of life caused by the bites of venomous snakes, or from loss of blood, or from serious injury, quantities which would, in the state of health, cause profound intoxication, are taken with impunity. The extremes of life — infancy and old age — bear considerable quantities of alcohol well, and are often remarkably benefited by them. Habitual use modifies still more de- cidedly the immediate influence of this agent on the functions of calor- ification, of circulation, and of the nervous system. The differential diagnosis of acute alcoholism (lethal dose), of opium narcosis, concussion of the brain, cerebral haemorrhage, and haemor- rhage into the pons or medulla, is by no means easy. In the absence of the history, in any given case, it may be impossible to determine. The odor of the breath (of opium or alcohol) ; the state of the pupil (contracted from opium, unequal, or contracted or dilated from intra- cranial haemorrhage, contracted or dilated from alcoholic intoxica- tion) ; the muscular resolution (common to all these states) ; the slow, sighing, irregular, or stertorous respiration (may occur in either) ; the abolition of reflex movements (a final symptom in all), are in the nature of things fallacious. A man who has received a concussion of the brain, or had an intra-cranial haemorrhage, may have taken opium or alcoholic stimulants in quantity sufficient to impart a distinct odor to his breath, without otherwise being distinctly affected by it. The other signs are not sufficient in themselves to enable a decision to be reached. Hence the importance of an attentive examination of the surrounding circum- stances. In the absence of a trustworthy history, it were better to suspend opinion until the further developments of the case enable an exact diagnosis to be made. The numerous examples of errors fallen into by most competent observers should make the physician hesitate before pronouncing an opinion of " drunk " or " dying," in the sensa- tional language by which some of these cases of mistake have been characterized. ALCOHOL. 477 The treatment of acute alcoholism consists in the evacuation of the stomach by the stomach-pump of any unabsorbed alcohol ; the cautious inhalation of ammoniacal gas ; cold affusion to the head ; faradism of the muscles of respiration, external warmth, etc. As respects the post-mortem appearances the following have been observed : intense hyperemia of the gastric mucous membrane ; dis- tention of the right cavities of the heart, and of the great venous trunks ; hyperemia of the cerebral meninges, and serous effusion into the ventricles and subarachnoid spaces. Therapy. — Alcohol in small doses is a useful stomachic tonic. It is best taken for this purpose after or with meals. It is specially ser- viceable in the feeble digestion of old people, the atonic dyspepsia of the sedentary, and in the slow and inefficient digestion of convales- cence from acute diseases. It should be prescribed with caution in these cases, especially in the atonic dyspepsia of women and of seden- tary men, because of the danger that an alcohol habit may be formed. When it is prescribed in the convalescence of acute diseases, the stimu- lant should be withdrawn at the earliest period. Excellent results are obtained from the use of brandy in the apep- sia of infants. The summer diarrhoea, both of children and adults, may be arrested by a full dose of brandy. Irritating matters and un- digested food should be removed before the brandy is administered. The vomiting of cholera-morbus and of cholera may, frequently, be arrested by small doses of iced brandy (a teaspoonful in pounded ice every half-hour), or tablespoonful doses of iced champagne. Other forms of vomiting, when due to irritation or inflammation of the stomach — as, for example, the vomiting of pregnancy — can sometimes be promptly cured by the same remedy. It not unfrequently happens that, in delirium tremens, nothing is retained by the stomach, and the life of the patient is put into imminent danger, by reason of the failure of the food-supply to the blood. A little brandy and ice will some- times settle the stomach under these circumstances, and enable the patient to take and digest the much-needed aliment. Notwithstanding the theoretical objections which may be urged against this practice, clinical experience is strongly in favor of the use of alcoholic stimulants to counteract the depressing influence of certain agents on the action of the heart — as, for example, aconite, veratrum viride, conium, digitalis, and the poison of venomous snakes. Before commencing the inhalation of chloroform, an ounce or two of whisky or brandy should be given the patient. This serves a double purpose : it sustains the heart and prolongs the chloroform narcosis. Alcohol in some form is constantly prescribed in low conditions in fevers, acute inflammations, and depressing maladies of all kinds. It is serviceable in these diseases when it lessens the pulse rate, but in- creases the contractile power of the heart and elevates the arterial 478 CEREBRAL SEDATIVES. tension. It does harm when the pulse becomes more rapid and the blood-pressure is lowered by it. It does good when the tongue, be- fore dry, becomes moister under its use, and harm when the ''dryness of the tongue is increased. It does good when the temperature is re- duced, the delirium and subsultus lessened, and the sleep becomes more continuous and refreshing ; and does harm when it increases fever, exaggerates the delirium, and induces coma vigil. The chief utility of alcohol in these forms of disease is not as a stimulant, but as a food. It furnishes material, easily oxidizable, which can be ap- plied as nervous, muscular, and gland force. Furthermore it stimulates digestion, and enables more food to be taken and disposed of, and thus contributes indirectly to the maintenance of the powers of life. It follows from these considerations, that alcohol should be given in these low conditions of the organism, with milk, eggs, broth, and other suitable aliment. Undoubtedly the stimulant treatment of adynamic states is often carried to great excess. The large doses of alcoholic substances ad- ministered, disorder the stomach and suspend digestion ; and thus the condition of things which they are intended to relieve is only made worse. Furthermore, stimulants are excessively used in these disor- ders, from a wrong notion of their therapeutic action, and a conviction that diseases characterized by depression are best treated by arterial stimulants. The reaction which has set in against the antiphlogistic methods is in part answerable for the great freedom with which alco- hol is now used in fevers and inflammations. As respects its action on the nervous system, alcohol is a narcotic. It may be used to relieve pain, to promote sleep, and to quiet delirium. The various neuralgim may be temporarily alleviated by intoxicating doses of alcohol, but such a prescription is dangerous to the moral health of the patient. The subjects of neuralgia, or those who possess the neurotic temperament, have as a rule an inherited or acquired weakness of constitution, and a mobility of the nervous system, which render the effects of alcoholic stimulants peculiarly grateful. When wakefulness is due to a condition of cerebral anwmia, a full dose of some alcoholic fluid, whisky or brandy, will procure sound and refreshing sleep. In some subjects a glass of ale or beer answers better. Some cases of delirium tremens are greatly benefited by alco- holic stimulants. When the delirium is the result of sudden excess and of the direct action of the alcohol on the cells of the gray matter, the use of this agent will only add to the existing disorder ; but when, as is so frequently the case, the attack is determined by the failure of the stomach to appropriate not only the stimulant but the food also, the careful administration of alcoholic stimulants with suitable aliment renders an incontestable service. ALCOHOL. 479 As alcohol stops waste, promotes constructive metamorphosis by- increasing the appetite and the digestive power, and favors the depo- sition of fat, it is directly indicated in chronic wasting diseases, espe- cially in phthisis. Clinical experience is in accord with physiological data : alcohol is an important remedy in the various forms of pulmo- nary phthisis. It is frequently given with cod-liver oil, or an ounce or two of whisky may be taken with some bitter or aromatic imme- diately after meals. If alcohol disagrees, if it does not improve but lessens the appetite, it will do harm in phthisis. It is an interesting fact that an intractable form of phthisis is induced by alcoholic excess. External Applications of Alcohol. — Equal parts of alcohol and water is an excellent evaporating lotion for the relief of superficial in- flammations — bruises, inflamed joints, orchitis, etc. Alcohol is an ex- cellent hemostatic for restraining oozing from a large surface. For suppurating wounds alcohol is an efficient antiseptic dressing — it de- stroys germs, removes fetor, and stimulates the tissues to more healthy growth. It favors the cicatrization of open wounds by coagulating the albumen and thus making an impermeable covering. It is a useful practice to wash the parts threatened with bed-sores with whisky or alcohol ; it hardens the cuticle, and prevents ulceration. /Sore nipples may be prevented by washing them with brandy after the child nurses, and then dusting them with bismuth carbonate. Brandy-and-water is an excellent lotion for mercurial and other forms of stomatitis requir- ing stimulant applications. Brandy-and-water is one of the thousand injections used in gonorrhoea.

(White wine, seven parts ; alcohol, one part.) (TJ. S. P.) These are the only wines recognized by the United States Pharma- copoeia. In medical practice a great variety are employed, in accord- ance with special indications. It would occupy too much space, and be foreign to the purpose of this work, to enter into details in regard to particular wines, but some attention should be given to the different groups. Sparkling Wines. (Champagne, sparkling catawba, etc.) — These are wines which have been bottled before the stage of fermentation has been completed, hence they are lively, or sparkling, in consequence of being charged with carbonic acid. A considerable portion of the grape-sugar has not been converted into alcohol ; they are sweet wines, therefore, and the quantity of absolute alcohol which they contain is relatively low (eight to twelve per cent). Sparkling hock is a lighter wine than champagne, and contains less sugar. Sparkling catawba more nearly resembles hock than champagne. A sophistication now much practiced consists in adding to still wines carbonic-acid gas, by pressure, in the same manner that carbonic- acid water is manufactured. Dry Acid Wines. — The best specimens of this group are the Ger- man Rhine and Moselle wines, California hock, and Ohio and Kelly- Island catawba. The German varieties are very numerous, and are remarkable for their flavor, for the completeness of the fermentation (absence of sugar), and for their permanence. The most important of the varieties are the following : Durkheimer, Ungsteiner, Hoch- heimer, Deidesheimer, Forster, Rudesheimer, Johannisberger, Lieb- frauenmilch, etc. The French wines are, as a rule, rather acid. The best known are the clarets, but these are more properly classed with the red wines. Sweet Wines. — In this group are contained burgundy, still cham- pagne, muscatel, malaga, Hungarian tokay, and angelica, madeira, etc. The alcoholic strength of these wines, unless fortified, is rela- tively low, because the sugar has not been consumed by the fermen- tation. Light Red Wines. — The French clarets, the red Rhine wines, the American Ives's seedling, and Concord and Hungarian, are members of this group. They contain a large proportion of the coloring-matter of the grape, and considerable tannic acid. WINE. 481 Heavy Red Wines. — Port is the principal representative of this group, but it is not a natural wine ; during the process of manufacture spirit is added, and its alcoholic strength is raised to thirty or forty per cent. California port when fortified, as it probably frequently is, should be classed in this division. Dry Spirituous Wines. — The most important member of this group is sherry. Composition and Properties. — The composition of wine is ex- tremely complex. The constituents ascertainable by chemical analysis do not represent all of the peculiar qualities which render various wines desirable. Bouquet and flavor can not be determined by the most expert chemist, and elude all other means of investigation but the tongue and nose of the " wine-taster." A wine is a solution of alcohol in water, mixed with various con- stituents of the grape. The proportion of alcohol ranges from six to forty per cent — the largest quantity being found in the artificial wines, such as port and sherry. The proportion of sugar varies greatly — from three to twenty-five per cent. The acids are fixed (tartaric) and volatile (acetic). The relation between these several constituents is nearly as follows : Port contains about fifty-three parts by weight of alcohol to one part of acid, and twelve parts of sugar to one part of acid. The average of sherry is thirty-nine of alcohol and 1*5 of sugar to one of acid. In the sweet wines, the average is about thirty parts of sugar to one part of acid and fifteen parts of alcohol. In the acid wines, the average proportion of alcohol to acid is as eighteen to one, while the sugar is almost absent, and in some of the best is entirely so. Those are dry wines which are free from sugar. Besides tartaric and acetic acids, wines contain, in much smaller quantity, malic, tannic, and carbonic acids. Wines containing less than three hundred grains of acid to the gallon are wanting in flavor ; on the other hand, an ex- cess of acid over five hundred grains to the gallon is too sour to be agreeable. The coloring-matter of wine varies greatly, and the dis- tinction between " white " and " red " depends on the quantity present in these different varieties. The red wines are more astringent, due to the larger proportion of tannin which they contain, and they are also rougher to the taste. Wine contains a great many mineral constituents ; tartrates of po- tassa and lime, chlorides of sodium, potassium, and calcium, and sul- phates of potassa and lime. The percentage of ash ranges from 0*18 to 0*40. Note. — Among the best wines for medicinal use are the Hungarian wines of Mr. L. Reich, of New York. The tokay has fine bouquet and flavor and good body, and the red wine is a claret of excellent quality. These wines are to be commended because they present satisfactory evidence of being the product of the fermeutation of pure grape-juice. 31 482 CEREBRAL SEDATIVES. The peculiar odor of wine (bouquet) is due to cenanthic acid, and cenanthic ether, produced by a reaction of the acid on the alcohol. According to Fresenius, the quality of a wine is so much the better the less it contains of free acid, the more it contains of sugar, and the greater its quantity of extract / and, further, its quality is not de- cidedly influenced by the quantity of alcohol, and can not be deter- mined by its specific gravity. A certain quantity of free acid is necessary, but it should not be greater than can be masked by the alcohol, sugar, and extractive mat- ter. The flavor and odor of wine are produced by ethers formed by the action of the free acid on the alcohol ; hence the importance of this acid constituent. Dr. Druitt, in his " Report on Cheap Wines," has very welL summed up the qualities of good wine in the following conclusions : " 1. The wine should have an absolute unity, or taste as one whole. " 2. Wine should contain a certain amount of alcohol. " 3. Wine should be slightly sour. " 4. Sweetness is characteristic of a certain class of wines, while certain other wines are dry, or free from sugar. " 5. Wines should have a taste free from mawkishness, and indica- tive of instability. " 6. Roughness or astringency is a most important property, and belongs to most red wines. In moderation it is relished, as sourness is, by a healthy, manly palate, just as the cold souse is welcome to the skin. In excess it leaves a permanent harshness on the tongue. " 7. The wine must have body. This is the impression produced by the totality of the soluble constituents of wine — the extractive, that which gives taste to the tongue, and which, as wine grows older, is deposited along with the cream of tartar forming the crust " 8. Bouquet is that quality of wine which salutes the nose. Fla- vor is that part of the aromatic constituent which gratifies the throat. " 9. The wine must satisfy. A man must feel that he has taken something which consoles and sustains. Some liquids, as cider and thin wines, leave rather a craving, empty, hungry feeling after them." Physiological Actions. — As respects the alcohol which they con- tain, the physiological actions of wines could be discussed with the previous article. But wines differ from alcohol, and from brandy and whisky, not only in spirituous strength, but in the possession of the varied and important constituents mentioned above. The sparkling wines are more sedative to the stomach, and are more intoxicating, relatively to their alcoholic strength, than the other wines. As they contain a considerable quantity of unappropriated sugar, acid fermentation is apt to occur, and acidity, with headache, follows their use. As respects the influence on the pulse, they are less stimulating than the stronger wines, and the experiments of Dr. Ed- WINE. 483 ward Smith have demonstrated that they increase the excretion of car- bonic acid. The dry acid wines are more purely stimulant, partly in conse- quence of their alcohol, and partly in consequence of the important ethers which they contain. As they are free from sugar, acid fermen- tation does not follow their use, but with some subjects the free acid present in them disagrees. The sweet wines have, generally, considerable body and alcoholic strength. They rather pall on the appetite ; are apt to disorder the stomach, and produce headache. Some of them have fine bouquet and flavor, and are satisfying to the palate ; but as a rule they are not borne as well as the dry wines. The red wines, light and dark, are astringent and have considerable body and alcoholic strength. The tannin which they contain, and coloring-matters, are apt to cause stomach-disorders, constipation, and a febrile state. By reason of the large amount of alcohol in them, especially in port, they approach whisky and brandy in power as stimulants and narcotics. Therapy. — " Good wine is a good familiar creature, if it be well used." (Othello.) The effervescing or sparkling wines often render important service in irritable states of the stomach without inflammatory action. The vomiting of pregnancy, of seasickness, of yellow fever, of cholera- morbus, icith depression, and of true cholera, are not infrequently ar- rested by tablespoonf ul-doses of iced champagne every fifteen minutes. A generous glass of a dry wine (sherry) taken with the principal meal greatly assists the digestion of the sedentary who suffer from atonic dyspepsia. The wine should be taken during the course of the meal, and at no other time. Persons who suffer from acidity, due to an excess of formation of acid gastric juice, are relieved by a dry acid wine, taken during the meal or just previously. For this purpose a genuine Rhine wine — for example, Forster Riesling — is best. In diarrhoea and dysentery, after the acuter symptoms have sub- sided, and when there is ' considerable depression, those wines are in- dicated which contain tannin — the red wines, claret, Ives's seedling, port, etc. In cases of anaimia and chlorosis, wines render an important ser- vice by increasing digestion and assimilation. To aid in this process, red wines with a good deal of sugar and extractives are most neces- sary. When wines produce headache, and the digestion is disordered by them, and the appetite impaired, they are not serviceable in these maladies. Moreover, for the nervous and hypochondriacal, wines must be prescribed with caution, for the habit of indulgence is quickly ac- quired by such subjects. In convalescence from acute diseases, there 484 CEREBRAL SEDATIVES. can be no difference of opinion as to the great value of wine as a restorative. Wines of considerable body and alcoholic strength are indicated under these circumstances. When there is much nervous restlessness, wakefulness, and cardiac depression, a wine rich in ethers is specially useful, according to Anstie. In chronic wasting diseases, as phthisis, scrofula, etc., the stronger wines, as sherry, burgundy, port, may take the place, in some cases, of the spirits, whisky and brandy. In these wasting diseases, wines serve a double purpose : they stimulate the activity of the primary assimilation, and within certain limits they are utilized as foods. They are only harmful when digestion is impaired by them ; and under no circumstances can they take the place of other aliment. In passive haemorrhages, in the hemorrhagic diathesis and in pur- pura, wines are indicated, because they elevate the arterial tension, and thus act indirectly as haemostatics. In various acute diseases, when the action of the heart becomes feeble and irregular, the pulse dicrotic, and there occur wakefulness and delirium, a wine of considerable alcoholic strength and rich in ethers is peculiarly serviceable. Wines are much more largely used in fevers {typhoid, typhus, etc.) than in any other forms of disease, and the circumstances requiring their employment are indicated in the preceding sentence. The routine practice of alcoholic stimulation in fevers can not be justified. Exact indications for the use of wine exist in the state of the heart and arterial system, and of the brain, and these should be sought for in eveiy case, instead of prescribing for the name. In fevers, wines precede the spirituous liquors. The first weakening of the heart's action, the beginning of dicrotism, and the transitory delirium and subsultus, require champagne and the light and acid wines ; more profound adynamia, with diarrhoea, the stronger red wines. In acute inflammations (pneumonia, pleuritis, peritonitis, etc.), wines serve to maintain the strength when the powers of life are weakening, or to maintain the functions of brain and heart when crises occur, as in pneumonia. The rules for the administration of wine in acute inflammations are the same as in fevers. Next to their use in fevers, wines are most frequently prescribed, and with the greatest advantage, in surgical practice, for the conse- quences of wounds and injuries, to support the powers of life under protracted and profuse suppuration, and to favor digestion and as- similation in the course of convalescence from surgical diseases. The immediate stimulant effect of wine is of great value in sudden and profuse loss of blood, whether from injuries and surgical opera- tions, or post partum. A highly-etherized wine of good body is most useful here, because it produces a prompt effect and easily yields up the force needed to keep the heart and brain in action, and, in the MALT LIQUORS. 485 case of the relaxed uterus, to furnish the power needed to procure its energetic contraction. Beer, Ale, Porter. — Beer and ale are fermented liquors made from malted grain, hops and other bitter substances being added. Ale is produced by rapid fermentation, in which the yeast rises to the sur- face, and beer is the product of slow fermentation in cool cellars, the yeast falling to the bottom. Hence the name lager-beer. Porter em- braces the qualities of beer and ale, and is so named on account of its strong quality, which endeared it to porters. Composition. — The proportion of alcohol varies somewhat. In Edinburgh ale it amounts to about six per cent ; in brown stout, to six per cent ; in porter, to four per cent ; in beer, two to three per cent. Besides alcohol and water, these malt liquors contain extract of malt, five to fourteen per cent ; carbonic acid, 0'16 to 0*60 per cent. In the extract are found also various aromatic substances, lactic acid, potash and soda salts, etc. Physiological Actions. — So far as the alcohol is concerned, beer, ale, and porter correspond in physiological actions to the spirituous liquors and to wines. As they contain malt extract, their nutritive value is greater than spirits and wine. An important constituent, the hop, being an aromatic bitter, the tonic and stomachic qualities of these malt liquors are also greater than their congeners. The process of fermentation, however, lessens in a remarkable degree the nutritive and stomachic qualities of the constituents which enter into the com- position of malt liquors. Their value as foods is much exaggerated by the habitual consumers. They increase the appetite and favor the deposition of fat. Although the malt beverages do not cause to any- thing like the same extent the alterations in the nervous centers pro- duced by the spirituous, they induce other and almost as important structural changes. They set up in the organism fatty degeneration of various tissues, notably of the liver and heart. The habitual beer- consumer is known by his obesity, his flushed face, embarrassed breath- ing, puffy hands, yellow conjunctiva, etc. ; he is usually short-lived, and the end is reached by hepatic and cardiac disorders. It is certainly true that a moderate amount of beer may be taken daily, for a life- time, without any obvious impairment of the functions ; but excessive use produces with great certainty the unfavorable effects above de- scribed. Therapy. — Beer, ale, and porter are not usually prescribed in acute maladies. They are, however, much and justly esteemed as stomachic tonics and restoratives in chronic wasting diseases — for example, in convalescence from acute diseases and surgical injuries, in cases of profuse and protracted suppuration, prolonged lactation, diseases of the joints, scrofula, phthisis, etc. Strumpf finds, however, that alco- 486 CEREBRAL SEDATIVES. holic beverages only increase the amount of fat in milk, and not the quantity of milk as a whole. The malt liquors are harmful in all stomach-disorders with acidity, and in chronic affections of the liver, especially fatty liver. When these beverages do not improve the appetite, when they cause a sense of epigastric oppression, and when they coat the tongue, they are not beneficial. When wakefulness is due to cerebral ansemia, a glass of beer or ale at bedtime will frequently produce satisfactory sleep. Puerperal mania, delirium tremens, and acute maniacal delirium, when these symptoms coexist with a condition of adynamia, are greatly benefited by the liberal use of ale (pale or Edinburgh ale). The effect of this remedy is to arouse the appetite, to quiet delirium, and to produce sleep. In melancholia, excellent results are often obtained by the use of porter with a little tincture of opium. Extract of Malt. — Under this name is known a thick, sirupy liquid having a golden or yellowish-brown color, a sweetish taste, and the odor of malt. If properly prepared, it contains, besides the con- stituents of barley, the ferment diastase. It is much prescribed for its restorative qualities, and as a vehicle for cod-liver oil. It is best administered immediately after meals. Paraldehyde has recently attracted so much attention as an anodyne and hypnotic, that some reference to it becomes necessary. Under this name is described a polymeric modification of aldehyde. Above the temperature of 51° Fahr. it is a colorless liquid, having a peculiar ethereal odor, and a specific gravity of *998. It boils at about 225° Fahr. It is soluble in eight parts of water at 52° Fahr. The dose ranges from 3 ss to 3 ijss. Water is a suitable menstruum. In appropriate cases it has proved to be an admirable hypnotic, with many of the qualities but none of the dangers of chloral. In its action, first the cells of the cerebrum are affected, and sopor is induced. Unlike the other agents of this class, its soporific action is not pre- ceded by excitement (Cervello). Next to the cerebral hemispheres the effects of paraldehyde are expended on the medulla oblongata, and then on the spinal cord. A lethal dose stops the functioning of the medulla and the respiratory center, but the cardiac functions cease after the respiratory. It differs from chloral in the important respect that it has no paralyzing action on the heart. The effect of paralde- hyde is, however, not so persistent as that of chloral, but the frequent repetition of the former with safety is more than a sufficient compen- sation for the greater power of the latter (Albertoni). Paraldehyde may be prescribed as a hypnotic in the conditions usually requiring such a remedy — in fevers, rheumatism, gout, prurigo, etc. (Morselli). It is, however, in mental and nervous disorders that it is likely to be most employed. By the Italian physicians, to whom ETHER. 487 we owe its introduction, it has been very successfully used in acute mania, in the wakefulness of dementia paralytica, in hysterical seiz- ures, and in ordinary insomnia. To succeed, it must be given in sufficient quantity. The maximum dose mentioned above ( 3 ijss) has often been given without any ill effect or any after-trouble of any kind. iEther.— Ether, fiiher, Fr. ; Aether, Ger. A liquid composed of about seventy-four per cent of ethyl oxide, and about twenty-six per cent of alcohol containing a little water. Specific gravity about 0*750 at 60° Fahr. (IT. S. P.) ^Zther Fortior. — Stronger ether. A liquid composed of about ninety-four per cent of ethyl oxide, and about six per cent of alcohol containing a little water. Specific gravity not higher than 0*725 at 60° Fahr. A thin, very diffusive, clear, and colorless liquid, of a refreshing, characteristic odor, a burning and sweetish taste, with a slightly bit- ter after-taste, and a neutral reaction. It is soluble in all proportions in alcohol, chloroform, benzol, benzin, fixed and volatile oils, and dis- solves in eight times its volume of water at 60° Fahr. It boils at 98*6° Fahr. Ether is highly inflammable, and its vapor, when mixed with air and ignited, explodes violently. (U. S. P.) Spiritus ^Etheris. — Spirit of ether. Consists of ether, thirty parts ; alcohol, seventy parts. Dose, ttj, x — 3 j. Spiritus ^Etheris Compositus. — Compound spirit of ether. Hoff- man's anodyne. (Ether, alcohol, and ethereal oil.) A colorless, vola- tile, inflammable liquid, having an aromatic, ethereal odor, and a burning, slightly sweetish taste. Its specific gravity is 0*815. It is neutral, or but slightly acid to litmus. It gives only a slight cloudi- ness with chloride of barium ; but when a fluid ounce of it is evapo- rated to dryness with an excess of this test, it yields a precipitate of sulphate of barium, which, when washed and dried, weighs six and a quarter grains. When a few drops are burned on glass or porcelain, there is no visible residue, but the surface will have an acid taste and reaction. A pint of water, by the admixture of forty drops, is ren- dered slightly opalescent. Dose, til x — 3 j. (Pharm. 70.) Spiritus ^Etheris Nitrosi. — Spirit of nitrous ether. Sweet spirit of nitre. An alcoholic solution of ethyl nitrite, containing five per cent of the crude ether. (U. S. P.) Is a volatile, inflammable liquid of a pale-yellow color, inclining slightly to green, having a fragrant, ethereal odor, free from pungency, and a sharp, burning taste. It slightly reddens litmus, but does not cause effervescence when a crys- tal of bicarbonate of potassium is dropped into it. When mixed with half its volume of official solution of potassa previously diluted with an equal measure of distilled water, it assumes a yellow color, which 488 CEREBRAL SEDATIVES. slightly deepens, without becoming brown, in twelve hours. A portion of the spirit in a test-tube half filled with it, plunged into water heated to 145°, and held there until it has acquired that temperature, will boil distinctly on the addition of a few small pieces of glass. Spirit of nitrous ether has a specific gravity of 0*837, and contains five per cent of its peculiar ether. It should not be long kept, as it becomes strongly acid by age. Dose, 3 ss — f ss. either Aceticus. — Acetic ether. Acetate of ethyl. A transparent and colorless liquid, of a strong, fragrant, ethereal, and somewhat ace- tous odor, a refreshing taste, and neutral reaction. Soluble in all pro- portions in alcohol, ether, and chloroform, and in about seventeen parts of water. Specific gravity, 0*889 to 0*897. It is inflammable. Dose, m x— 3 j. Ethyl Bromide. — Hydrobromic ether. Is a colorless liquid, vol- atile, having a fragrant odor, and a hot, somewhat sweetish taste, afterward rather bitter. It is not inflammable. Its specific gravity is 1*420, and it boils at 104° Fahr. ; readily decomposes on exposure to light and air, bromine being separated. It is freely soluble in alcohol and ether, but very sparingly in water. Dose, for internal and sub- cutaneous administration, tt], x — 3 j. Antagonists and Incompatibles. — Ether dissolves iodine, bro- mine, corrosive sublimate, the volatile and fixed oils, many resins and balsams, tannin, caoutchouc, most of the alkaloids, sulphur, and phos- phorus — the last-named two sparingly. As respects its stimulant and anodyne properties, it is antagonized by arterial sedatives, quinine, oxygen, protoxide of nitrogen, the tetanizing alkaloids, strychnine, picrotoxin, etc. Synergists. — Alcohol and its congeners, chloroform, arterial stimu- lants, cerebral stimulants, etc., assist the action of ether. Physiological Actions. — The physiological effects of ether when inhaled require separate treatment ; hence the subject of anaesthesia by vapors will be discussed in a special article. It is now proposed to treat of the effects of ether administered by the usual route — the stomach. Ether has a taste at first sweetish, but afterward hot and pungent. It leaves a cooling sensation in the stomach after the subsidence of the burning, and this quickly diffuses over the body. Increased action of the heart, flushing of the face, warmth of the surface, with increased diaphoresis, follow in a few minutes. The senses are quickly excited, the mind becomes more active, ideas flow rapidly, and the cerebral phenomena of alcoholic intoxication ensue. These effects are of short duration, and a feeling of content, mental calm, and sopor, succeeds to the transient excitement. Ether is eliminated rapidly, chiefly by the lungs, and the whole duration of the effects of even a large quan- tity ( 3 ij) does not exceed an hour. ETHER. 489 Therapy. — Before it is administered, ether should be diluted with alcohol, which renders it readily miscible with water. A few drops of Hoffman's anodyne (th, x — in, xx) in some camphor- water is an excellent remedy to expel flatus from the stomach. Gas- tralgia may often be quickly relieved by the same means. A few drops of ether, added to cod-liver oil, enable the stomach to bear it more easily, and, it is said, favors its digestion ; that it accomplishes this object by increasing the pancreatic juice, is the observation of Claude Bernard. Paroxysms of hepatic colic are sometimes treated by the internal administration of ether, but this treatment is by no means equal in effectiveness to the inhalation of the vapor. Ether mixed with turpentine has the power to dissolve hepatic calculi, hence the remedy of Durande. As Trousseau well remarks, chemical results which take place in the laboratory are not reproduced in the body with equal facility. The rapidity with which ether diffuses into the blood at the temperature of the stomach would appear to preclude the possibility of its exerting any solvent action on a calculus fixed in an hepatic duct. Whatever good result is secured by the administration of the remedy of Durande must be ascribed to the anodyne and anti- spasmodic action of its constituents. Sudden failure of the heart' 1 s action (syncope), from mental emo- tion or hysteria, is most promptly remedied by the administration of Hoffman's anodyne. Mild attacks of angina pectoris, and of spas- modic asthma, may sometimes be aborted by a full dose of the ethe- real preparations. The subcutaneous injection of ether is very effec- tive in sudden cardiac depression. Nervous or hysterical sick-headache is quickly cured by 3 ss doses of spirit of ether. The most important application of these ethereal remedies is in the treatment of the hysterical paroxysms. As the ac- tion is prompt and quickly expended, it is obvious that ether or Hoff- man's drops are only adapted to sudden hysterical seizures, and not to more lasting nervous symptoms arising in an hysterical constitution. Nothing can be more satisfactory than the prompt relief by these agents of hysterical flatulence, globus hystericus, and hystero-ep>ilepsy. $ Spts. etheris composit., tinct. valerian, amnion., aa J j. M. Sig. : A teaspoonful in water every flfteen minutes until relieved. As a cardiac stimulant in fevers, the ethereal preparations are oc- casionally prescribed. For a quick effect, in an emergency of practice, they are useful, but are not equal to spirits and wine when a sustained effect is required. Nitrous ether is employed in domestic practice as a mild diapho- retic, a diuretic, and carminative. It no longer occupies the place it formerly held in medical practice, but it is occasionally prescribed in feverishness, as a constituent in expectorant mixtures, in combination icith diuretic medicines, etc. 490 CEREBRAL SEDATIVES. Ether by the Hypodermatic Method. — Within the past few years, the subcutaneous injection of ether has taken an important posi- tion in therapeutics. It is necessary, therefore, to enter into this sub- ject fully. When ether is injected beneath the skin, more or less burning pain is felt at the point of insertion, and a puffy swelling is produced. In most subjects this swelling subsides in an hour or two, and no trace is left of the operation. In some instances, an induration, the size of a filbert, forms, and slowly disappears. Yery rarely inflammation is set up about the site of the injection, and followed by suppuration, with more or less sloughing. If not too large an amount, suddenly and vio- lently injected, is used, there will be no untoward results. The effects of ether subcutaneously are the same in kind as, but more powerful in degree than, those produced by the stomachal admin- istration. A local anaesthetic impression is made ; in a few seconds, the action of the heart is powerfully increased, and soon the usual cere- bral effects are manifest. Ether was first employed subcutaneously by Dr. Comegys, of Cin- cinnati, in the treatment of sciatica. He injected from fifteen minims to a half-drachm, in the neighborhood of the affected nerve. This practice has been followed by others with success, and is now more or less widely used as a substitute for " the deep injection of chloroform." It is very desirable to have some exact observations which will deter- mine the comparative value of these expedients. The most important applications of ether, hypodermatically, are as a cardiac stimulant in the case of sudden and extreme depression of the heart, and as a general stimulant in adynamic states. In the de- pression caused by haemorrhage, whether pulmonary or post partum, the injection of ether may obviate the necessity for transfusion. This practice is strongly urged by Peter, Fereol, and Mile. Ocoumkoff, who report cases in confirmation. Remarkable results have been effected by the subcutaneous injection of ether in adynamic pneumonia (ty- phoid pneumonia), as practiced by M. Barth. Thus, of fourteen cases of severe type treated by these injections, eleven were cured. The quantity injected was about fifteen to twenty minims two, three, or four times a day, according to the degree of adynamia. The effects which follow almost immediately are these : the respiration becomes more easy, the pulse takes on more strength and volume, the tongue moistens, and the countenance assumes a better appearance. In from two to three minutes after the injection has been practiced, the odor of ether is recognizable in the breath (Barth). In the eruptive fevers, especially in variola, the injections of ether have been used with admirable results (Castel). It is in a high degree probable that the same treatment will prove very useful in low forms of septic and inflammatory diseases in general. There can scarcely CHLOROFORM. 491 be any doubt that we have in this method a most useful addition to our therapeutical resources. In place of ether, hydrobromic ether has been utilized in the treat- ment by the subcutaneous method of various spasmodic diseases, as ic hooping-cough, chorea, asthma, and similar affections. Chloroformum. — Chloroform. Chloroforme, Fr. ; Chloroform, Ger. Chloroformum Venale. — Commercial chloroform. A liquid con- taining at least 98 per cent of chloroform. It has nearly the same sensible properties as purified chloroform. Its specific gravity should not be lower than 1*470. Chloroformum Purification. — Purified chloroform. A heavy, clear, colorless, diffusive liquid, of a characteristic pleasant ethereal odor, a burning sweet taste, and a neutral reaction. Soluble in about two hun- dred parts of water, and in all proportions in alcohol or ether ; also in benzol, benzin, fixed or volatile oils. Sp. gr. 1*485-1*490 at 60° Fahr. If five cubic centimetres of purified chloroform be thoroughly agi- tated with ten cubic centimetres of distilled water, the latter, when separated, should not affect blue litmus-paper (absence of acids), nor test-solution of nitrate of silver (chloride), nor test-solution of iodide of potassium (free chlorine). If a portion be digested warm with solu- tion of potassa, the latter should not become dark-colored (absence of aldehyde). If a few cubic centimetres be permitted to evaporate from blotting-paper, no foreign odor should be perceptible after the odor of chloroform ceases to be recognized. (U. S. P.) When shaken with an equal volume of sulphuric acid, in a bottle closed by a glass stopper, and allowed to remain in contact twenty- four hours, no color is imparted to either. "When one fluid drachm is evaporated spontaneously with one drop of a neutral, aqueous solution of litmus, the color of the latter is not reddened. The result of the test is the same if the chloroform contained in a white glass bottle has been previously exposed to direct sunlight for ten hours. Mistura Chloroformi. — Chloroform mixture.- Purified chloroform, eight parts ; camphor, two parts ; fresh yolk of egg, ten parts ; water, eighty parts. M. Dose, a tea to a tablespoonful. Spiritus Chloroformi. — Spirit or chloroform. Purified chloroform, ten parts ; alcohol, ninety parts. Dose, 3 ss — 3 j. Antagonists and Incompatibles. — Chloroform separates from the mixture when prescribed with weak spirits or glycerin. It is soluble in alcohol (ten to six), in ether (one to seven), in water (one to two hundred). It dissolves very freely in olive-oil and turpentine, but does not dissolve in or mix with glycerin. It has very extensive solvent power, dissolving caoutchouc, gutta-percha, mastic, tolu, benzoin, co- pal, among the gums ; iodine, bromine, the organic alkaloids ; fixed and volatile oils, resins, and fats. In cases of poisoning by the inter- 492 CEREBRAL SEDATIVES. nal administration of chloroform, the treatment should be conducted on the same plan as for irritant poisons. There is no chemical anti- dote. To overcome its effects on the respiratory and circulatory sys- tems, artificial respiration, cold affusion, and galvanism, may be em- ployed. Synergists. — Anesthetic agents, opium, chloral, alcohol, etc., pro- mote the action of chloroform. Physiological Actions. — The taste of chloroform is hot, sweetish, and pungent. Undiluted it excites violent irritation and inflammation of the mucous membrane. In passing through the fauces the vapor may enter the larynx in such quantity as to cause great heat and in- flammation, followed by oedema. In the stomach, chloroform produces a feeling of warmth, followed by coldness, like ether ; but, when taken in large quantity undiluted, violent gastritis. Besides the local action, chloroform diffuses into the blood, and affects distant parts. Like alcohol and ether, it increases the action of the arterial system, and occasions excitement of the brain, followed by sopor. In lethal doses profound stupor and insensibility are produced by it. Therapy. — A little chloroform (t7[ ij — v\ v), dropped on sugar and swallowed, will remove some kinds of nausea and vomiting. It can be useful in non-inflammatory states only, as, for example, seasickness, the vomiting of pregnancy, sick-headache, etc. Gastralgia may some- times be relieved in the same way. The following formula is an effec- tive remedy for flatulent colic : IJ Spirit, chloroformi, tine, carda- momi comp., aa § ij. M. Sig. : A teaspoonfid every half-hour in water. Hepatic and saturnine colic are also benefited by chloroform, but the addition of opium increases its efficacy, and is usually neces- sary in these cases. Chloroform is a solvent of biliary calculi, and has been prescribed with the view to effect a solution of calculi con- tained in the gall-bladder, or lodged in the hepatic duct. It undoubt- edly affords some relief, but not probably because of its solvent action. As has been remarked of ether, it is in the highest degree improbable that sufficient chloroform, even when it is administered in large doses, can reach the calculus to effect its solution, when experi- ments out of the body have shown that some hours are required to dissolve a calculus immersed in chloroform.

The vapor of chloroform may be applied directly to these parts. In hay-asthma, whooping-cough, spasmodic asthma, irritable reflex cough, the vapor of chloroform may be used as follows : To a cup of warm water, 80° to 100° Fahr., add a teaspoonful of spiritus chloro- formi, and repeat every five minutes. This inhalation should not be used except in the presence of a medical man, and not more than five teaspoonfuls should be inhaled at a time. The patient should inhale CHLOROFORM. 493 the vapors as they arise, directing them into the air-passages from the cup by a paper shield. A little chloroform (a minim or two) is a use- ful constituent of expectorant mixtures, when a neurotic element is present. Chloroform is a very valuable hypnotic in delirium tremens. It is unsafe when used by inhalation in the treatment of this affection, but, by the stomach, not unfrequently excellent results are obtained from it. It is contraindicated when there are a vigorous action of the heart and an elevated state of the arterial tension, and useful when symp- toms of depression and adynamia are present. It should be given in the form of the spirit. I£ Spirit, chlorof ormi, tinct. capsici, aa f j. M. Sig. : A teaspoonful in water every half -hour, hour, or two hours. Neuralgia. — Chloroform is extremely valuable in the treatment of this disease, and it is the most effective when used by the method of " deep injection," first proposed by the author. This plan of treat- ment consists in the injection deeply, in the neighborhood of the affected nerve, of five to fifteen minims of pure chloroform. The offi- cial spirit of chloroform, ether, or even alcohol, may be used for this purpose. The first named, in the quantity of fifteen minims, is prob- ably the best. Rarely does any local mischief result from these in- jections, except a temporary induration. The author has procured by this means apparently permanent relief to long-standing cases of neu- ralgic pain (tic-douloureux) affecting the superficial divisions of the fifth. Other practitioners have been equally successful, and the cases thus treated now include neuralgic affections of the most important nerves. Pain in superficial nerves may sometimes be relieved by the local application of chloroform. $ Chlorof ormi, tinct. aconiti rad., aa § ss ; liniment, saponis, f j. M. Sig. : Liniment. A piece of flannel, moist- ened with this, is applied to the painful part, evaporation being pre- vented by a covering of oiled silk. The pain of dysmenorrhea is relieved by the local application of chloroform-vapor, and of sciatica, lumbago, myalgia, and similar affections, by chloroform applied di- rectly to the parts. Nervous headache may sometimes be cured by a little chloroform in a watch-glass applied to the temple. An impending paroxysm of intermittent may be prevented by a full dose of chloroform ( 3 j — 3 ij ) administered before the onset of the chill. The inhalation of chloroform is used for the same purpose. A few drops of chloroform, frequently repeated, is an excellent means of relief in cholera. It allays nausea and vomiting, arrests diarrhoea, relieves the cramps, and restores the temperature. It may be given in the form of spiritus chlorof ormi, or of chlorodyne, a very celebrated empirical remedy. No single remedy has been more effica- cious than chlorodyne in the treatment of true cholera. 494 CEREBRAL SEDATIVES. Chloroform as a Counter-irritant. — When chloroform is applied to the skin and evaporation prevented, it causes heat, redness, and even vesication. Frequently, chloroform is used locally to produce this effect, but usually in combination with other counter-irritants, IJ Chlorof ormi, ol. terebinthinas, aa § j ; lin. saponis, f ij. M.

These are elegant counter-irritant applications, in cases requir- ing the milder remedies of this class, and are used in various internal inflammations and local affections characterized by pain. Commercial chloroform can be used in preparing them. Chlorodyne. — This empirical preparation is largely used in cholera, and in painful diseases requiring an anodyne. Numerous formulas have been published, but none of them appear to possess the exact qualities of the original preparation by Dr. J. C. Browne. The dose of the genuine chlorodyne ranges from ten to thirty drops. The following formula makes a product more nearly resembling the original than any other known to the author : Chloroform 4 ounces. Ether 1 ounce. Alcohol N . 4 ounces. Treacle 4 ounces. Extract of licorice 2^ ounces. Muriate of morphine 8 grains. Oil of peppermint 16 minims. Sirup 17-J- ounces. Acid, hydrocyan. dil 2 ounces. Dissolve the muriate of morphine and the oil of peppermint in the alcohol, mix the chloroform and ether with this solution, dissolve the extract of licorice in the sirup, and add the treacle ; shake these two solutions together, and add the hydrocyanic acid. Dose, five to fifteen minims. Some of the published formulas contain resin of cannabis Indica, atropine, perchloric acid, in addition to the ingredients above given. Another chlorodyne, known as " Gilman's," has many advantages, and is now widely used. Its composition is as follows : Purified chlo- roform, 3 ij ; glycerini, f ij ; spts. vini rect., J ij ; acid, hydrocanic. dil., 3 ij ; tinct. capsici, 3 ij ; morphinas muriatis, gr. viij ; syrupi (treacle), | iij.

Neither of these anaesthetics should be used until its conformity to the standard of the United States Pharmacopoeia has been ascertained. The tests of purity are given under their respective heads in the pre- ceding article. The term anaesthetic, proposed by Dr. Oliver Wendell Holmes, means an agent capable of producing ancesthesia, or insensibility to pain. It is true, anaesthesia is a term which, according to its etymo- logical signification, should be applied to loss of sensation of touch, chiefly, and analgesia should be used to signify loss of the sense of pain ; but the word ancesthesia, as expressive of the state of profound unconsciousness induced by anaesthetics, is now so firmly established by usage that it were better to retain it. Insensibility to pain (anal- gesia) may be produced, without simultaneous loss of common sensation, touch (anaesthesia). By the inhalation of ether, chloroform, bichloride of methylene, nitrous oxide, and some other agents, the functions of animal life can be so far suspended that surgical operations involving intense pain, and certain natural processes, accompanied by great suf- fering, can be performed entirely without the consciousness of the subject concerned. Physiological Actions. — When the vapor of ether or chloroform is inhaled, a sense of faucial irritation and of the need of air is expe- rienced, and more or less cough is produced. The irritation of the fauces excites the flow of mucus, and the reflex act of swallowing. The feeling of need of air causes the patient to push aside the inhaler or sponge, and in children may lead to violent struggling. The sensi- bility of the glottis is soon diminished, the coughing ceases, and the inhalation then proceeds quietly. 496 CEREBRAL SEDATIVES. The first effect is a general exhilaration, the pulse increases in fre- quency, the respirations become more rapid, and sometimes assume a sobbing or convulsive character ; the face flushes ; talking, laughing, crying, singing, and sometimes praying, indicate the cerebral intoxica- tion. This stage of excitement varies in duration in different indi- viduals, and is more pronounced in character and more persistent in those of mercurial disposition, and in the hysterical. At this period, although the patient can be easily aroused, sensibility to pain is de- cidedly diminished ; although the sense of touch may be preserved, taste and smell are abolished, and the sight is either abnormally acute or is perverted by illusions. If the inhalation be continued, the patient passes into the condition of complete insensibility. In women and children, and males reduced by illness, the production of insensibility, if the anaesthetic be not inhaled too rapidly, takes place quietly ; but, if the subject be a robust male, in full health, especially if the inhala- tion has been proceeded with rapidly, the stage of insensibility is pre- ceded by a tetanic convulsive stage, in which the voluntary muscular system and the respiratory muscles become rigid, the breathing ster- torous, the face cyanosed. This condition of rigidity is similar to, if not identical with, the tetanic stage of the epileptic paroxysm. If the inhalation of the anaesthetic be pushed still further, the tetanic rigidity subsides, the cyanosis disappears, the breathing proceeds quietly, and a condition of complete muscular relaxation, and of abolition of reflex movements, is established. When this is accomplished, the arm drops without resistance when let fall, the conjunctiva is insensible to irri- tation, the pupils do not alter in size when exposed to light, and no mechanical irritation awakens the least consciousness of pain. The surface is cool, and bathed with abundant perspiration, the counte- nance is placid, the eyes closed, the pupils rather contracted than di- lated ; the respiration easy, but more shallow than normal ; the pulse slower — it may be feebler, it may be stronger than in health. The functions of the cerebrum are suspended ; only the lower centers, pre- siding over respiration and circulation, continue in action. Out of this condition, and without interference, the patient will presently emerge. If, however, the inhalation be continued, these organic functions will be suspended, and life will be terminated by the cessation of the action of the heart and of the respiratory organs. There are several modes of dying from anaesthetic vapors : 1. By the first mode, the death is sudden and occurs very soon after the inhalation has begun, and is ascribed to "irritation of the peripheral nervous system, accumulation of carbonic acid in the blood, and arrest of the action of the heart." This explanation, the author submits with diffidence, seems very unsatisfactory, for phenomena of this kind, up to the point of cardiac paralysis, must ensue in all cases of chloroform narcosis. The sudden death, at the beginning of inha- ANESTHETICS. 497 lation, seems to be more properly explicable on the theory tbat the first chloroform vapor which reaches them paralyzes the cardiac gan- glia, already in an abnormal state of susceptibility from causes not now understood, for this accident sometimes occurs in persons who have previously taken the anaesthetic without unfavorable symptoms of any kind. 2. By the second mode, called by Richardson epileptiform syncope, death ensues in the stage of rigidity preceding complete muscular relaxation, and is due to tetanic fixation of the respiratory muscles, and consequent interference with the pulmonary circulation, accu- mulation of blood on the venous side, and arrest of the heart's action. In these cases respiration ceases before the pulsations of the heart cease. 3. By paralysis of the respiratory muscles. Death ensues during the stage of complete muscular relaxation, and the action of the heart continues for some seconds, or even minutes, after respiration has ceased. 4. By paralysis of the heart. This also occurs in the course of complete insensibility ; the motor ganglia are paralyzed, and the heart suddenly ceases to act, the respiration continuing for a short time longer. 5. This mode of dying is made up of two factors : depression of the functions by chloroform narcosis, and the shock of the accident, or the surgical operation. Death may ensue during the inhalation, or may occur afterward. COXDITIOXS OF THE OeGANISM EEXDEEIXG THE USE OF AxJES- thetics daxgeeous. — Experience has demonstrated that old drunk- ards are peculiarly unfavorable subjects. When tumor or abscess of the brain exists, it is dangerous to administer anaesthetics. Instances of sudden death under these circumstances are relatively numerous. Very much enlarged tonsils, swollen epiglottis, oedema of the glottis, are contraindications, but not insuperable, to the use of anaesthetics. Emphysema of the lungs is so frequently accompanied by ischaemia of the arterial, and engorgement of the venous side of the systemic circulation, and with dilatation of the right cavities, that it must be considered a dangerous state in which to administer chloroform, or even ether. Fatty change in the muscular substance of the heart must be considered peculiarly unfavorable, for more deaths have en- sued from this cause than any other. Chloroform and ether have been administered with safety in cases of phthisis and heart-disease (valvular lesions), the muscular substance and its contained ganglia being free from structural change. Experience has abundantly demonstrated that those reduced by illness and disease, and the feeble, bear anaesthetics better than the healthy and robust ; that children and women are better subjects than 32 498 CEREBRAL SEDATIVES. adults and men ; that anaesthetics are safer when given for operations for disease than for injury. Incomplete anaesthesia is a condition of danger. Numerous acci- dents have occurred from the use of anaesthetics for trivial operations — notably for extraction of teeth — in which but a partial degree of insensibility is induced. In such cases the heart, enfeebled by chloro- form narcosis, is suddenly paralyzed by the reflex action proceeding from the peripheral injury. The district of tissue supplied by the fifth nerve is an especially dangerous region, owing doubtless to the intimate connection of the nucleus of the fifth with the nucleus of the pneumogastric. By far the largest number of fatal cases have resulted from a neglect of this rule : it is never safe to proceed in a surgical operation with anaesthetics, unless complete insensibility has been pro- duced. The author is aware that Trousseau and Pidoux have attrib- uted the number of cases of fatal chloroform narcosis, which have occurred in England, to the fact that the just-mentioned rule is ad- hered to by English surgeons. Their words are as follows : " En Angleterre, les chirurgiens portent V etherisation jusqu?d V abolition de toutes les facultes animales i jusqu'au commencement de la periode d'etherisme orga,nique. Plus prudents sous ce rapport que leurs con- freres de la Grande- Br etagne, les chirurgiens franpais ont V habitude de s'arreter des que la sensibilize aux excitations de la peau est abolie et que la resolution musculaire commence. Cette prudence explique comment les chirurgiens franpais ont eprouve moins d 'accidents graves et compte moins de morts subites." (Vol. ii, p. 322.) Modes of conducting the Inhalation. — After ascertaining that none of the contraindications mentioned above exist, the patient may be prepared for the inhalation of the anaesthetic vapor. The inhala- tion should not be proceeded with soon after a full meal. Vomiting, as the narcosis subsides, is usual, and, as the insensibility of the glottis persists for some time afterward, particles of food may be lodged in the chink, causing fatal suffocation. Several cases of this kind have been reported. On the other hand, it is bad practice to administer an anaesthetic after a prolonged period of fasting, for the exhaustion thereby induced may be an influential factor in determining a fatal result. Before the inhalation is begun, it is proper to administer an ounce or two of whisky or brandy. Much more important is the ex- pedient proposed by Bernard and afterward by Nussbaum, to premise a subcutaneous injection of morphine. Bernard proposed to administer the morphine before beginning the inhalation ; whereas Nussbaum used it after unconsciousness to pain had been produced. The ad- vantages of the former method are obvious. When the morphine influence takes place, the inhalation will proceed quietly without the struggling and coughing, and spasmodic breathing, which so interfere with the administration of anaesthetics, especially of ether. The use ANAESTHETICS. 499 of morphine subcutaneously also lessens materially, if not prevents entirely, the stage of rigidity and spasm. The quantity of the anaes- thetic required is much less, and the stage of insensibility more pro- longed, when morphine is thus given. Besides the foregoing conspicuous advantages derived from the preliminary subcutaneous injection of morphine, there can be no doubt that this agent antagonizes the paralyzing action of the anaesthetic on the cardiac and respiratory centers, and prevents the subsequent shock due to the administration of the ana3sthetic and the performance of a surgical operation. The proposal of Bernard, as subsequently advocated by Nussbaum, was some time afterward strongly urged by the late Prof. William Warren Greene, M. D., of Pittsfield, Massachusetts, and Dr. J. C. Reeve, of Dayton, Ohio. Soon after the publication of Bernard's observations, the author, in his "Manual of Hypodermatic Medica- tion," proposed the use of morphine and atropine combined as more perfectly realizing the object contemplated. Since this time, at Lyons, the combination of morphine and atropine has been largely employed preliminary to ether inhalation. The method is known as "anesthe- sies mixtes" or, anaesthesia by a mixed method (Aubert). The addi- tion of atropine is to increase the forces of the antagonism against the depression of the cardiac and respiratory functions. The experience of the Lyons school is decidedly in favor of the method of mixed an- aesthesia. Adverse reports from other quarters, however, have not been wanting, but the relevancy of their facts is doubtful. When the anaesthetic is about to be administered, the operator should, by a cheerful and confident manner, remove the fears of the patient. None of the paraphema of the operation to be performed should be exhibited before the patient, and no remarks should be made in his hearing regarding his case, the anaesthetic sleep, or the surgical procedure. Only the physician having the administration of the an- aesthetic in charge, and the necessary assistants, should be present in the apartment. An abundant supply of fresh air should be insured to the patient, and all the appliances required for resuscitation should be at hand, but not ostentatiously paraded before the patient. The simplest apparatus only is required. Complicated inhalers have, as frequently as the towel or the handkerchief, been used in fatal cases of chloroform narcosis. A cone of stiff paper, lined with lint or felt, and large enough to cover the nose and mouth of the patient, is the best form of inhaler for the administration of ether. Lente's ether-inhaler consists of a cone of hard rubber lined with felt, and having attached to the apex a flexible rubber tube communicating with the ether-bottle. This is a very satisfactory apparatus. A simi- lar but much less complicated and expensive inhaler is that of Dr. Allis, of Philadelphia. The utility and desirableness of this apparatus are 500 CEREBRAL SEDATIVES. much commended by Prof. William Goodell. When ether is inhaled, the atmosphere is, as far as possible, excluded, in order that the anaes- thetic effect may be quickly induced. The important point in the administration of chloroform is to secure such an admixture of atmos- pheric air as that the amount of chloroform-vapor shall not exceed three and a half per cent. If this rule be regarded, the form of in- haler is of little importance. The original method of Simpson con- sisted in applying the vapor by dropping slowly chloroform on a piece of thin cloth laid over the mouth and nose, or by a linen handkerchief moistened with half a drachm. The mouth and nose should be pro- tected from the irritant action of the chloroform by inunction with oil. A cone made of a towel, having a large opening at the apex, and containing a suitable, very porous sponge, is now probably more em- ployed than any other form of inhaler for giving chloroform. The typical method for administering it is that of Snow : in a bag of suit- able size the vapor of chloroform is mixed with air in the proper pro- portion, and then given directly ; but, obviously, such an arrangement is not often available. In administering the vapor of chloroform by any of the modes in use, it should not be forgotten that it has a density and weight four times those of air, and that, consequently, when a cloth or handker- chief is held closely over the mouth, the air is displaced, and the pa- tient may be breathing little more than chloroform-vapor. During the administration of ether, attention should be directed to the state of the respiration, for arrest of the respiratory movements is the only source of danger. When chloroform is being inhaled, the state of the circulation, as well as of the respiratory apparatus, must be regarded. Means of removing Dangerous Symptoms. — Suspension of the heart's action is to be met at once by the withdrawal of the vapor, and the inversion of the patient, according to the method of Nelaton ; failure of respiration, by forcibly drawing out the tongue, by the practice of artificial respiration, and by faradization of the respiratory muscles. Artificial warmth should be applied, and cooling of the body by cold-water douche, etc., should be prohibited. Acupuncture of the heart, galvano-puncture, injection of ammonia into the veins, are meas- ures which have been used in extreme cases, but unfortunately rarely with success. Amyl nitrite, by inhalation or subcutaneously, has proved very useful in some cases. Schirmer arouses patients by irri- tating the nasal mucous membrane by means of a roll of paper of suit- able size, and this may be #nade more exciting by dipping the end in aqua ammonia. Alcoholic stimulants — whisky or brandy — have often been used nypodermatically with asserted advantage. At the present time the subcutaneous injection of ether is the popular expedient. It is, however, very questionable whether the administration of alcohol or one of its derivatives can be useful in a condition of things brought AESTHETICS. 501 about by an anaesthetic of alcoholic origin. The author believes, in- deed, that serious mischief is done by this practice in cases capable of resuscitation. In practicing resuscitation for arrest of breathing due to ether, artificial respiration by the method of Silvester, faradization of the chest-muscles, and inversion of the body by the method of Nelaton, are the most promising expedients. Therapy. — Anaesthetic agents are used to quiet pain and spasm from disease, to render the dressing of injuries and surgical operations painless, and to produce muscular relaxation. Ether-inhalations give entire relief to the pain of neuralgia (tic-douloureux), cancer, and in- flammation ; to pain dependent on spasms — tetanus, chorea, hepatic and nephritic colic, etc. It is not necessary in these cases, as a rule, to induce full anaesthesia, for, as has already been pointed out, the sensibility to pain ceases before the condition of insensibility is reached — before, indeed, the perceptive centers of conscious impressions are otherwise impaired than as to the appreciation of pain. Paroxysms of maniacal delirium, and of puerperal mania, when violent and uncon- trollable, are sometimes quickly quieted and refreshing sleep obtained, from which the patient eventually arouses in a calmer frame of mind. Ether is the proper agent for this purpose. It should not be forgotten that anaesthetics are dangerous in delirium tremens. In puerperal convulsions due to reflex irritation, or to urcemia, the use of chloroform is invaluable. It is equally effective in the reflex con- vulsions of early life, in the urazmic convulsions of scarlet fever, and in the so-called hystero-epilepsy. When puerperal or other forms of convulsive seizures are due to cerebral haemorrhage, no good can be accomplished by anaesthetic inhalations. In any case, although con- vulsions may be arrested by anaesthetic inhalations, other appropriate measures must be resorted to for the permanent removal of the causes. A paroxysm of epilepsy impending may be aborted by the inhalation of ether, but the nitrite of amyl is a more effective remedy for this purpose. In certain neuroses of the respiratory organs, great relief is ob- tained by anaesthetic inhalations. Laryngismus stridulus may be quickly cured by the vapor of chloroform. A few drops of chloroform on a handkerchief will suffice, and special care should be taken to dilute the vapor largely with air. A similar procedure will relieve severe paroxysms of whooping-cough, but a more energetic use of chloroform is required when convulsions occur during a fit of coughing. Xo single agent gives more relief in asthma, but, like all other remedies for this disease, the power of relief declines, and increasing doses of the anaes- thetic become necessary, so that the habit of chloroform or ether nar- cosis is formed. Anaesthetic inhalations should not be recommended in cases which 502 CEREBRAL SEDATIVES. will probably require their use for a long time, because the inclination for this kind of intoxication grows rapidly, and is as difficult to control as the opium-habit. The author has seen one case in which the patient consumed a pound of chloroform daily, but, as might be expected, this extraordinary consumption of the anaesthetic did not long continue, for the patient succumbed in a few months. In obstetric practice the applications of anaesthetics are numerous and important. The indications and contraindications for chloroform in natural labor may be f ormularized as follows : When the labor is of short duration, and not excessively painful, anaesthetics should not be used ; on the other hand, when the labor is protracted and the suffering great, they favor the progress of the case and prevent exhaustion and uterine inertia. In primipara caution is necessary. The inhalation of the anaesthetic should not begin until near the close of the first stage, unless those painful but ineffectual contractions occur which have been aptly characterized as "nagging pains," when the vapor, very much diluted, may be cautiously inhaled for their relief. The inhalation should be practiced only during the existence of the pain. The influ- ence of the anaesthetic on the pulse, respiration, and uterine contrac- tions, should be carefully observed, and, if the pulse fail, the respirations become shallow, or the pains lose in efficiency, the inhalation should be discontinued. If the anaesthetic cause great excitement, and the patient become loudly clamorous for more, while the uterine contractions are lessening in force, it is doing harm and should be withdrawn. It is never necessary, nor proper, to administer the anaesthetic to complete unconsciousness. Toward the close of the second stage, when the head begins to distend the external parts, the quantity of chloroform may be somewhat increased, but the inhalation should be discontinued when the occiput has passed under the pubic arch. If these rules are fol- lowed, the action of the anaesthetic is beneficent. Properly adminis- tered, the use of chloroform may be considered perfectly safe in the parturient female. It is generally conceded that no well-authenticated case of death from the use of chloroform in labor has occurred, when the administration was in the hands of a properly-qualified medical man. The following evil results, the author believes, have followed the incautious use of anaesthetics in labor : the progress of the case arrested, so that forceps became necessary ; slow and imperfect uterine contrac- tions, and consequent post-partum haemorrhage ; a toxic condition of the mother's blood, with after - excitement, wakefulness, and puerperal mania ; asphyxia of the child, tedious convalescence, and subinvolution of the womb. When instrumental delivery is required, the utility of anaesthetics is unquestionably great. It facilitates the necessary manipulations, and prevents shock. The inhalation should be carried far enough in these cases to produce sufficient quietude in the patient, and it may be to ANAESTHETICS. 503 complete muscular resolution. When turning is to be performed, the state of chloroform narcosis must be deep enough to suspend uterine contractions. If puerperal convulsions occur at any stage, the utility of chloro- form is unquestionable. The limits of its utility in these cases have already been indicated. When careful examination of the pelvic viscera is to be made to establish the diagnosis in difficult and obscure cases, as, for example, phantom tumor, ovarian and fibroid growths, pelvic abscess, etc., the importance of full anaesthesia can hardly be over-estimated. The use of anaesthetics in operative surgery is now an indispensable practice. It may be compendiously stated that ether, or chloroform, is required in all surgical operations of magnitude, for the reduction of dislocations, for the taxis in strangulated hernia, for dressing painful toounds and adjusting fractures, for breaking up adhesions, and con- tractions of muscles and tendons in cases of deformity, for establishing the diagnosis in feigned diseases, etc. The after nausea and vomiting, which are sometimes most depress- ing, and occasionally dangerous, produced by anaesthetics, may be pre- vented by the hypodermatic injection of morphine and atropine before beginning the administration of the anaesthetic. After the patient emerges from the anaesthetic sleep, the above-mentioned unpleasant after-effects may be relieved by a minute quantity of morphine (y 1 ^ of a grain) and atropine (y|-g- of a grain) injected subcutaneously. Comparative Utility of Ether and Chloroform. — Chloroform is more pleasant to inhale, and is less irritant to the air-passages than ether. The vapor of chloroform is not, and the vapor of ether is, in- flammable, whence it follows that the former may be alone admissible at night under some circumstances. The stage of excitement is longer from ether than from chloroform, but, as ether may be given much more rapidly, this difference in action may be made to disappear in practice. Chloroform is more prompt in its effects, and the narcosis induced by it more sustained, than is the case with ether ; but these advantages possessed by chloroform are quite balanced by the greater freedom with which ether may be administered. The danger from the inhalation of chloroform is vastly greater than from ether. It folloics from the above considerations that ether should be used in preference to chloroform in all cases, except during labor. Chloro- form is to be preferred in labor, because more pleasant to inhale, more prompt in action, and without inflammability. The consideration of safety must necessarily take precedence, but experience has shown that chloroform is perfectly safe in labor when properly administered. The frequency with which fatal cases of chloroform narcosis have been reported — amounting in the aggregate now to about five hun- dred — imposes an immense responsibility on the administrator. In the 504 CEREBRAL SEDATIVES. present state of opinion on the subject, the use of chloroform, when ether is available, for the production of anaesthesia, can hardly be jus- tified, especially if a fatal result follow its administration. Ethyl Bromide. — The physical properties of this ether are men- tioned on another page in connection with ether. As an anaesthetic, it was first known to Mr. Nunnely, of Leeds, and he first employed it in surgical practice in 1865. Dr. Turnbull gave an account of its prop- erties, based on experimental and clinical evidence, in 1877, but the most extended trials of its anaesthetic powers were made by Dr. Levis, of Philadelphia, in 1879-'80. In the latter year two unsuccessful cases occurred, one in the hands of Dr. Levis, its chief promoter, and the other in the practice of Dr. Marion Sims, of New York. These fatal cases, and some crude physiological experiments, undertaken to prove that ethyl bromide is a heart-paralyzer, started a reaction against this anaesthetic, then beginning a promising career, and in a short time it fell into almost complete disuse. It has, however, valuable properties which should preserve it from neglect. To induce complete insensi- bility, from four to six grammes ( 3 j — 3 jss) must be administered rap- idly. The odor is not unpleasant, and but little irritation of the air- passages is produced. If administered in full quantity, there is a very brief (scarcely noticeable) stage of excitement, and the period of rigid- ity is very short and not pronounced. The face is flushed, the ears red, the eyes injected, and the pupils are more or less dilated. The action of the heart is accelerated, and the pulse increases in force. The respiration is also somewhat quickened, and in some subjects be- comes snorting or stertorous, but irregularity or arrest of the respira- tory movements has not occurred. More or less embarrassment of breathing has been occasionally caused by an accumulation of bron- chial mucus. It does not often induce nausea and vomiting ; but women are more apt to be disturbed in this way than men. The du- ration of the stage of insensibility is brief and the awakening prompt, with little of the confusion of mind and excitement characteristic of ether and chloroform. As a rule, the patient wakes out of the anaes- thetic condition with little distress of any kind. In the fatal cases recorded, there are strong doubts in regard to the share of ethyl bromide in the result. In Dr. Levis's case the pa- tient was far advanced in pulmonary disease, and was unfit for the administration of any anaesthetic. In Dr. Sims's case the death of the patient occurred a number of hours after the operation, which was a tedious one, requiring very protracted use of the anaesthetic. It is said that a strong odor of bromine pervaded the entire body of this sub- ject. It is, however, in a high degree improbable that decomposition of the ethyl bromide takes place when it is inhaled. In administering this anaesthetic the method pursued with ether is ANESTHETICS. 505 best. If given promptly, in sufficient quantity, and but slightly di- luted with air, the stage of insensibility can be induced in about five minutes (Levis). It is not suited to operations requiring much time. It is, however, peculiarly well adapted for slight or brief operations of a very painful character, and for ophthalmic practice it is unequaled, according to Chisolm. M. Perier states that he has used ethyl bromide very often as a local anaesthetic, instead of ether, and, he affirms, with great success. The method to which he refers is local anaesthesia as inaugurated by Richardson with the spray -douche. Among other distinct advantages over ether, ethyl bromide is not inflammable, and can consequently be used under circumstances prohibiting the former. The inhalation of ethyl bromide has been utilized in the treatment of diseases for the relief of which the bromides have been given by the stomach. MM. Bourneville and Oilier have carefully investigated this action of ethyl bromide in hysteria and epilepsy. They find that hysterical seizures are promptly arrested, and that in epilepsy the daily administration of this remedy during a period of two or three months notably diminishes the frequency of the attacks. This prac- tice might be advantageously extended to the treatment of severe chorea, ichooping -cough, spasmodic asthma, hepatic and renal colic, etc. For these purposes, only sufficient ethyl bromide is inhaled to relieve the pain or spasm, or to induce sopor. Bichloride of Methylene. — This agent, similar to chloroform, was first proposed as an anaesthetic by Dr. B. W. Richardson. It is more agreeable to inhale, and less apt to produce after-sickness, than chloro- form, but it is not less, and probably more, dangerous to life. Five or six deaths have occurred in the cases in which methylene bichloride was administered. Spencer Wells has constantly used it since it was introduced, without a single untoward result. But he employs a spe- cial administrator, and gives the vapor with a regulated supply of air. His apparatus consists of a mask closely fitting over the mouth and nose, connected by a flexible tube with a bottle containing the anaes- thetic, and with a rubber hand-ball, which sends into the mask, with every contraction of the bulb by the hand, this quantity of air with the anaesthetic vapor. As no accidents have happened, and yet pa- tients are kept narcotized for hours at a time, there can be no doubt of the security afforded by this method of conducting the inhalation. It were well if this plan were applied to the inhalation of chloroform as well as bichloride of methylene. Authorities referred to : Anstie, Dr. Francis Edmund.

Artificial Anaesthesia, Philadelphia, 1882. Local Anaesthesia. — The diminution of the cutaneous sensibility, by the application of ice and freezing mixtures, has long been practiced. It was not, however, until Richardson's method by the hand-ball spray apparatus had been proposed, that there had been much use made of local anaesthesia. This method consists in directing a current of atomized ether against the part to be anaesthetized. The ether employed for this NITROUS OXIDE. 507 purpose should have a specific gravity not to exceed 0*723. Rhigolene, the lightest liquid known, a product of the fractional distillation of petroleum, is more effective than ether, but great difficulty attends its use, owing to its extreme volatility. When a current of atomized ether or rhigolene is directed against the skin, the rapid evaporation produces an intense degree of cold, in consequence of which the nerves lose their power of transmitting impressions to the sensorium. A serious drawback to the process of producing local anaesthesia is the unpleasant burning which follows in the part when it recovers from the freezing, and also the great pain which attends the applica- tion of ether-spray to certain parts. Therapy. — For small operations, such as extraction of teeth and ope?iing abscesses, the method of local anaesthesia is extremely useful. It has been and can be used with entire success in much larger opera- tions, but it is generally employed for merely minor ones. The application of ether-spray to the spine is an extremely service- able remedy in spinal irritation and in chorea. In the latter disease it alone suffices to effect a cure. In neuralgia of superficial nerves, lumbago, muscular rheumatism, etc., the ether-spray affords relief very quickly, which may be permanent. Nitrous Oxide. — Protoxide of nitrogen. Laughing-gas. Composition and Properties. — A colorless, inodorous gas, having a slightly sweetish taste, and a specific gravity of 1*527. It consists of one equivalent each of nitrogen and oxygen. It increases the rate of combustion of inflammable substances. Water at ordinary temper- ature absorbs about three fourths of its bulk of the gas. By pressure and cold the gas may be condensed into a liquid, and can then be stored up in suitable vessels for transportation and use. The quantity of the gas taken up by cold water may be much increased by pressure, and the water will then yield it up on heating. Hence this constitutes a convenient mode of storing the gas for preservation. The ordinary mode of storing the gas is in gas-bags holding about eight gallons, in gasometers, or in the liquid form in strong metallic casks. Physiological Actions. — The first surgical operation performed with a modern anaesthetic was the extraction of a tooth, the subject being unconscious from the inhalation of nitrous oxide. It had long been known that this gas produced decided exhilaration when inhaled to a certain point. It has a very short anaesthetic stage, unless the in- halation of the gas be continued. The first effect of the inhalation of nitrous oxide is a subjective dizziness, whirring noises in the ears, and tingling and loss of sensa- tion throughout the body. Extraordinary illusions beguile the senses, and the intoxicated subject suddenly breaks forth into singing, decla- mation, sobbing, melancholy, or manifests a pugnacious tendency and 508 CEREBRAL SEDATIVES. assaults those about him. As the effects quickly cease, and as the return to consciousness is very abrupt, the subject is surprised and ashamed to find himself in some ridiculous or grandiose position quite foreign to his usual demeanor. When used to produce anaesthesia for surgical operations, the inha- lation of the gas is forced, and the stage of excitement is very brief. The countenance assumes a frightful aspect, most alarming to those who have not witnessed the inhalation of the gas. The face becomes deadly pale, the respirations, at first shallow, soon assume a stertorous character, the jaw becomes fixed, the eyes protrude, and the pallor of the face is presently replaced by a bluish and purplish tint. So far as the exterior phenomena can afford any indication of the nature of the action, the condition produced by nitrous oxide is an asphyxiated state. The blood ceases to be oxygenated, carbonic acid accumulates, and the centers of conscious impressions are rendered in- active in consequence of the deficient supply of oxygen and the excess of carbonic acid. The rational indications of the nature of the narcosis produced by nitrous oxide are confirmed by physiological experiment. It has been found that the exhalation of carbonic acid is decidedly diminished by the inhalation of nitrous oxide, and that animals live no longer in an atmosphere of this gas than in an atmosphere of nitrogen. The inhalation of nitrous oxide appears to be almost free from danger, and it is rare that unpleasant after-effects follow its adminis- tration. Two fatal cases have certainly occurred, which can with pro- priety be attributed to the lethal action of this gas, and various cases have fallen under the observation of the author in which nervousness, vague mental symptoms, and headache, have been experienced after the inhalations. Therapy. — The very prompt action of nitrous oxide and the quick subsidence of the narcosis render it a very useful anaesthetic agent when small operations, quickly executed, are to be performed. It is especially adapted for the extraction of teeth, opening of abscesses, and similar minor operations. But it has also been used successfully for maintaining prolonged anaesthesia for the performance of capital oper- ations. There is no difficulty in keeping up insensibility from fifteen minutes to a half -hour, since the introduction of liquefied gas and of apparatus for its suitable application.

Chloral, Fr. ; Chloralhy- drat, Ger. Separate, rhomboidal, colorless and transparent crystals, slowly evaporating when exposed to the air, having an aromatic, penetrating, and slightly acrid odor, a bitterish, caustic taste, and a neutral reaction. Freely soluble in water, alcohol, or ether ; also soluble in four parts of chloroform, in glycerin, benzol, benzin, disulphide of carbon, fixed or volatile oils. It liquefies when mixed with carbolic acid and camphor. Dose, grs. v — 3j, or more, but it should not be forgotten that 3 ss has produced toxic symptoms. Antagonists and Incompatibles.- — The depression of the heart and respiration caused by chloral is antagonized by alcoholic stimu- lants, ammonia, atropine, by galvanism, and by artificial heat. These are, therefore, appropriate remedies to be employed in cases of poison- ing. Strychnine is held by Liebreich to be antagonistic, and hence it may be administered hypodermatically when the measures above men- tioned are being used. Alkalies decompose chloral with the production of formic acid and chloroform, hence all agents having an alkaline reaction are incompat- ible. Synergists. — The hypnotic medicines, notably opium, and the an- aesthetics, deepen the effects of chloral when they are simultaneously administered. Physiological Actions. — Chloral has considerable antiseptic prop- erty, and is preservative of animal textures. It produces redness and inflammation of the skin, when kept in contact with it for a lengthened period. The taste of chloral is hot and pungent, and it excites an abundant flow of saliva. In the stomach it causes first a cooling sen- sation, followed by warmth, and when taken in large quantity may set up a high degree of. gastric irritation, nausea, and vomiting. In mod- erate quantity chloral rather stimulates than impairs the appetite, and indigestion and nausea do not, as a rule, follow as an after-effect. Chloral diffuses into the blood rapidly. The changes which occur after its entrance into the vessels are much disputed. Liebreich, as is well known, was led — by observing the reaction when chloral is brought into the presence of an alkali — to the deduction that the soda of the blood would split up chloral into chloroform and formic acid, and that, therefore, the effects belonging to chloroform might be produced by the administration of chloral. It is probably true that this reaction does take place to some extent, but there are several insuperable objections to the theory of Liebreich : 1. The effects of chloral differ from those produced by a corre- sponding quantity of chloroform. 2. After the administration of chloral, there is no elimination of chloroform by the breath or urine. 510 CEREBRAL SEDATIVES. 3. Chloral is more decidedly hypnotic, and much less anaesthetic, than chloroform. 4. Crystals of chloral have been recognized in the blood, and the products of the decomposition of chloral have recently been recovered from the urine. The effects which follow an ordinary medicinal dose (fifteen to thirty grains) are not the same in all subjects, although it must be admitted that a great degree of uniformity exists. When there is present an insusceptibility to its hypnotic action it produces headache, and in some subjects a delirious excitement. Immediately preceding its hypnotic action there is developed in all subjects a stage of excite- ment, usually very short in duration, and followed by sudden and complete sopor. The sleep produced by chloral is extraordinarily like natural sleep, and is calm, dreamless, and refreshing. It is not a condition of narcotism, and the patient may be easily aroused to take food and nourishment, and will quickly and without difficulty fall asleep again. As a rule no unpleasant after-effects are experienced from a dose of chloral — no headache, faintness, giddiness, nausea, and constipation, so common after morphine. The quantity of chloral ne- cessary to produce sleep, without dangerous narcotism, ranges from fifteen to forty grains, and the duration of the effect varies in differ- ent subjects from two to eight hours. Chloral does not destroy the sensibility to pain, unless administered in a quantity sufficient to sus- pend the functions of the cerebrum. It is not a pain-relieving agent in the sense that morphine is. When sleep is produced by proper medicinal doses of chloral the pupil contracts a little, the pulse may remain unaltered or become slower, and the respirations are unaffected. When a dangerous or lethal dose is taken, profound narcotism will follow ; the respirations will be slower and shallower, the pulse will become weak, rapid, and irregular ; sensibility and the reflex movements will be abolished, and complete muscular relaxation will ensue. The mode of dying is by suspension of the functions of the cerebrum, and, finally, by paralysis of the respiratory center, and of the cardiac motor ganglia. Death may be suddenly produced by paralysis of the heart, in cases of fatty degeneration of the muscular tissue of this organ, without proceed- ing so far as to involve the lower centers of the brain. A marked reduction in temperature, notably in rabbits — so much as 8° Fahr. — is produced by chloral, but this effect may be considera- bly lessened by enveloping the body in non-conductors (Brunton), which act by preventing the cooling of the blood by the atmosphere. The first effect of chloral is to raise the arterial tension (stage of excitement), but this action quickly ceases, and a decided lowering of the tension results. The diminished arterial tension and the weak- ened action of the heart are the principal factors in the reduction of CHLORAL. 511 the body temperature, for the combined action of these agencies is to lessen the combustion process. After death from chloral, congestion of the meninges of the brain and cord, of the lungs, and distention of the right cavities of the heart, have been observed. The arrest of the heart's action takes place in the diastole. Chloral does not affect the motor nerves nor impair the contrac- tility of muscle ; hence the paralytic phenomena both of animal and of organic life produced by it are due to its direct action on the nervous centers. Very large quantities of chloral have been taken without pro- ducing fatal symptoms. I have seen a patient who took daily from two drachms to three drachms of chloral for many months, without any symptoms of acute poisoning. While it is true that enormous doses (several hundred grains) have been taken without producing lethal effects, it is equally true that serious symptoms and death have resulted from very moderate doses (twenty to thirty grains). Great care should therefore be taken in prescribing an agent of such uncer- tain power. A fatty heart, atheromatous degeneration of the vessels, advanced disease of the lungs, and instability of the nervous system, are contraindications of the use of chloral. Chloeal-Habit. — The habitual use of chloral constitutes a dis- order, which, if not as persistent as the opium -habit, has its own difficulties and dangers of no little importance. Those who take choral habitually have irritable, injected, and rather brilliant eyes, and are voluble in speech, and have a rather excited and hurried manner. They complain usually of singing in the ears, of an empty or vacuous feeling in the brain, and are subject to sudden attacks of vertigo. They are wakeful, and very nervous and excitable, without chloral, when the time for sleep arrives, and they are usually entirely unable to sleep without the usual dose of the hypnotic. During the day they are melancholy, easily fatigued, and their voluntary movements are apt to be uncertain and disordered. The appetite is always capricious, frequently wanting ; digestion is labored ; the secretion of bile is de- ficient, the stools being rather white and pasty ; the urine stained with the bile-elements, and sometimes albuminous. An increasing weakness and irregularity in the action of the heart ; dyspnoea, chiefly when the stomach is distended ; redness, injection, and ecchymoses of the skin, have been occasionally observed to occur in cases of the chloral-habit. The best method of managing these unfortunate cases consists in the very gradual diminution of the daily quantity of chloral ; in regu- lation of the diet and administration of a suitable supply of food ; air, exercise, and change of scene ; chalybeate tonics ; hyoscyamus and lupuline as calmatives, strychnine and picrotoxin as nerve stimulants ; occasional purgatives. 512 CEREBRAL SEDATIVES. Therapy. — Chloral is a remedy of great value in sea-sickness. From fifteen to thirty grains every four hours, the recumbent posture for a short time, and suitable nourishment, are the most effective means we now possess for this troublesome disorder. In some cases of sick- ness of pregnancy chloral is equally effective, but, like other remedies for this condition, it often fails. According to the author's observation, it is most effective when there is much dizziness, faintness, and repug- nance to food, and but little vomiting. When the odor of chloral invites nausea, as is not unfrequently the case, it may be given advan- tageously by enema. And, furthermore, rectal injection of fifteen to thirty grains, properly diluted, is an effective remedy for nausea and vomiting of reflex origin, as occur in cases of uterine fibroids, gastro- enteritis of children (Kjelberg), etc. In severe cases of cholera-morbus, with cramps, coldness of the sur- face, cold breath and cold tongue, remarkable relief is procured, and the patient not unfrequently wrested from a condition of extreme dan • ger, by the hypodermatic injection of chloral. There is no means of treatment of cholera now known so effective as this, as the author has personally witnessed. The effectiveness of chloral is increased by com- bination with morphine. I£ Chloral, hydratis, 3 iij ; morphinse sulph., gr. iv ; aquae laur.-cerasi, § j. M. Sig. : From fifteen to thirty minims — -for cholera, cholera-morbus, etc. This injection produces consider- able burning pain and an indurated lump, but in the author's expe- rience suppuration has not followed. As chloral produces a lowering of the temperature, and, according to Richardson, diminishes the coagulability of the fibrin, good results may be expected from its use in inflammations and fevers. It is es- pecially indicated when the temperature is high and there are much delirium and restlessness present. The author has observed excellent results from its use under these circumstances in the eruptive fevers, pneumonia, etc. It should not be forgotten, however, that chloral must be prescribed with caution when there is ischsemia of the arterial system — a condition which must necessarily exist when a considerable portion of the lung-space is blocked up by fibrinous or caseous de- posits. In pleuritis, endo- and pericarditis, and in peritonitis, much good will result from the use of moderate doses of choral — five grains every three hours. It is useful because it allays restlessness, causes sleep, lowers the fever, and limits or prevents fibrinous deposits and exudations. The most important uses of chloral are in diseases of the nervous system. As an hypnotic, pure and simple, it is quite unrivaled. Cases of sleeplessness, due to mental overwork, anxiety, or physical fatigue, are entirely relieved by fifteen to twenty grains of chloral. The re- freshing sleep thus obtained not unfrequently leads to repeated and long-continued use of chloral, and thus the chloral-habit is formed. It CHLORAL. 513 follows that sleep should be procured by proper hygienic methods in such cases, if possible, and chloral should be resorted to only after the failure of such means. No hypnotic is so uniformly successful in pro- curing sleep in delirium tremens ; but this remedy, as other remedies of the same class, not unfrequently fails. It is more particularly adapted to those cases in which the delirium has succeeded to a debauch, and is less useful, and may, indeed, produce serious symptoms, in old, worn- out drunkards. Violent excitement not unfrequently is produced by it when it fails to cause sleep. The author must caution his younger readers against the too large administration of chloral in this disease. Sleep may be procured which will end in fatal exhaustion. Especially should caution be used in the old drunkard, whose heart and vascular system may have undergone serious fatty and calcareous degeneration. In suitable cases there is no doubt chloral is a remedy of the highest value, but it should not be used to the exclusion of suitable hygienic and dietetic treatment. Various forms of mania, in which delirium and wakefulness are prominent symptoms, are largely benefited by hypnotic doses of chloral. This remark is true of acute mania, acute melancholia, puerperal mania, acute maniacal delirium, and the excitement which occurs in general paralysis of the insane. When it agrees, and pro- duces refreshing sleep, marked improvement in the mental state not unfrequently follows its use. In incurable and intractable cases, chloral often renders the greatest service as a calmative and an hypnotic. Puerperal convulsions, when the patient is in a condition to swal- low, may be arrested by full doses of chloral — twenty grains every two hours ; also, subcutaneously in five-grain doses, it is highly effec- tive, according to Purefoy, and by the rectum its acts admirably in many cases. Infantile convulsions, when due to reflex irritation, may be suspended by the same means. When the jactitations of chorea are so incessant as to prevent sleep, or when they occur during sleep, chloral may be administered with advantage. It is not a curative agent in chorea, but when it produces quiet and refreshing sleep it indirectly contributes to the cure. Some of the respiratory neuroses are greatly benefited by chloral. The paroxysms of spasmodic asthma may be arrested by it, and the spasmodic attacks of difficult breathing which accompany emphysema may be decidedly ameliorated by timely doses of chloral. It must not be forgotten, however, that the use of chloral is not unattended with danger in pulmonary diseases with ischsemia of the arterial system. In the spasmodic stage of whooping-cough, great relief to the parox- ysms maybe obtained by the use of this agent. From five to ten grains will generally be a suitable quantity for administration in these cases. Impending attacks of laryngismus stridulus may be prevented, 33 514 CEREBRAL SEDATIVES. and seizures already in action can be quickly arrested, by a full dose of chloral — five to fifteen grains. We have no remedy more effective in tetanus than chloral, but it must be given in large doses. Nocturnal attacks of epilepsy may not unfrequently be prevented by a full dose of chloral at bedtime. In paralysis agitans, good effects have been attained by hypnotic doses at bedtime. Chloral is a physiological antagonist to strychnine, and may, therefore, be used with advantage in poisoning by this substance. Chloral is not unfrequently prescribed to relieve pain, but under a mistaken notion of its physiological powers. It can only relieve pain by suspending the functions of the cerebrum, and in doses, therefore, which are dangerous. It has no direct pain-relieving power, like mor- phine. When pain is to be relieved and sleep procured, the combina- tion of chloral and morphine is extremely effective. Although chloral does not directly suspend the functions of the sensory nerves, it relieves certain kinds of pain due to irregular or overaction of un striped mus- cular fibers. Yery great relief is afforded by chloral to the irregular pains of the first stage of labor, which cause suffering but do not ad- vance the case — the so-called "nagging pains," in popular obstetric language. Rigidity of the os uteri and soft parts may be corrected by the timely administration of chloral, and exhaustion may be pre- vented by giving it in such a way as to suspend irregular uterine action and to procure sleep. After-pains are stopped by chloral. In all these cases of obstetric diseases, large doses are generally required. A solution of chloral is an excellent antiseptic application to foul wounds: it destroys the odor of putrefaction, arrests fermentative changes, and promotes the formation of healthy granulations. It may be used to preserve anatomical preparations and morbid specimens. A weak solution of chloral (gr. j to grs. iv — § j) is an excellent in- jection in gonorrhoea. Equal parts of chloral and camphor, triturated together, form a clear fluid, which is often of great service in neuralgia, applied to the affected part. It is painted lightly over the surface with a camel's- hair brush, and is allowed to dry on. It is said to allay spasmodic cough when painted over the larynx. The solution of camphor and chloral thus prepared has decided solvent properties. Morphine sul- phate will dissolve in it in the proportion of a scruple to two drachms, and chloroform can then be added without a separation of the ingre- dients. A mixture thus prepared is a very effective local application in superficial neuralgiw, and as an internal remedy in colic, cholera- morbus, cholera, etc. Authorities referred to : Amory, Dr. Robert.

Croton-Chloral Hydrate. — This substance occurs in rather small and brilliant tabular crystals. It is soluble in water, but not freely so ; and, as respects antagonists and incompatibles, may be classed with chloral hydrate. Dose, grs. ij — grs. xv, largely diluted in water. It may also be conveniently made into pills with glycerite of traga- canth. Physiological Actions and Therapy. — Croton-chloral resembles chloral in its hypnotic action, but it is feebler and also less certain. As in lethal doses it causes death by paralysis of respiration, it is admissible in cases of weak heart. It differs from chloral, especially in the singular property which it possesses of causing anaesthesia of the head. Croton-chloral is much less certain in its effects than chloral : sometimes one or two grains will relieve severe trigeminal neuralgia ; and often from five to fifteen grains are necessary. When pain is to be relieved and sleep procured, the best results are obtained by a com- bination of the two agents. Croton-chloral has proved very effective in various neuralgice. It has been especially useful in tic-douloureux, in which it should be given in doses of two to five grains every hour or two, until fifteen grains have been taken. It is probably not safe to exceed this amount at one time. The pains of dysmenorrhea and sciatica have also been relieved by the use of this remedy.

Composition. — About half of the weight of opium is made up of gum, pectin, albumen, fragments of the poppy-capsules, and cal- careous salts. It contains, also, some coloring-matter, and a volatile substance in minute quantity. The proportion of water varies from twelve to thirty per cent. A large number of basic, acid, and neutral substances have been and are still being discovered in opium, hence its chemistry is very complex. The following natural alkaloids have been found in opium. Vari- ous derivatives of these have also been described. This list, except some unimportant modifications, is taken from Fltickiger and Han- bury's admirable Pharmacographia : OPIUM. 517 Hydrocotarnine. — Crystallizable, alkaline. Volatile at 100°.

The only important derivative in the therapeutic sense is apomor- phine, obtained from morphine by the action of hydrochloric acid. This possesses active emetic property, and will be grouped with emetics. Besides the foregoing alkaloidal and basic substances, opium con- tains a peculiar acid (meconic acid), and, according to T. and H. Smith, a peculiar form of lactic acid (thebolactic). The proportion of morphine in Turkey opium should not be less than ten per cent, and in good specimens may reach fifteen per cent. Pseudo-morphine occurs in the minute quantity of 0*02 per cent. The proportion of codeine varies from one fifth to two fifths per cent. The- baine and papaverine exist in Turkey opium in about the proportion of one per cent. Narcotine is found in considerable quantity in differ- ent varieties of opium, and ranges in amount from one and five tenths to ten per cent. Narceine varies from 0*1 to 0*71. The quantity of cryptopine and rhoeadine is extremely small. The morphine of opium exists in the drug in the form of the tri- basic meconate. The proportion of meconic acid is about three to four per cent of the crude opium. 518 CEREBRAL SEDATIVES. The value of opium depends on the quantity of morphine which it contains. Morphina. — Morphine. In colorless crystals, which are inflammable and wholly dissipated by red heat. It is scarcely soluble in cold water, slightly so in boiling water, and freely soluble in boiling alcohol. Nitric acid first reddens it, and then renders it yellow. With a solu- tion of sesquichloride of iron, it assumes a deep-blue color. Its so- lution restores the color of litmus, previously reddened by an acid. (IT. S. P.) Morphince Acetas. — Acetate of morphine. A white, yellowish- white, crystalline or amorphous powder, slowly losing acetic acid when kept for some time and exposed to the air, having a faintly acetous odor, a bitter taste, and a neutral or faintly alkaline reaction, When freshly prepared, the salt is soluble in twelve parts of water and in sixty-eight parts of alcohol ; if it has been kept for some time, it is incompletely soluble in water, unless a little acetic acid is added. Dose, g r - i~ g r - ss - Morphince Hydrochloras. — Hydrochlorate of morphine. In snow- white, feathery crystals, wholly soluble in water and in alcohol. Dose, g r - -1— gr. ss. Morphince Sutyhas. — Sulphate of morphine. In snow-white, feath- ery crystals, which are wholly soluble in water. Dose, gr. £ — gr. ss. Pulvis Morphince Compositus. — Compound powder of morphine (Tully's powder). (Morphine sulphate, one part ; camphor, twenty parts ; glycyrrhiza, twenty parts ; precipitated carbonate of calcium, twenty parts ; and sufficient alcohol to make a mixture.) Dose, gr. j — gr. x. Trochisci 3Iorphince et Ipecacuanhce. — Troches of morphine and ipecacuanha. (Morphine, ipecac, sugar, oil of gaultheria, mucilage.) Codeina. — Codeine. White, or yellowish-white, more or less trans- lucent, rhombic prisms, somewhat efflorescent in warm air, odorless, having a slightly bitter taste and an alkaline reaction. Soluble in eighty parts of water at 60° Fahr. and in seventeen parts of boiling water ; very soluble in alcohol and in chloroform ; also, soluble in six parts of ether. Dose, gr. ss — gr. ij. Various salts of codeine are now prepared, but the sulphate is the most important and desirable. The other alkaloids of opium are not official. JVarcotince Hydrochloras. — Hydrochlorate of narcotine (not offi- cial). Dose, gr. ij — gr. x, as an antiperiodic. Antagonists and Incompatibles. — As regards chemical antago- nism, the alkaline carbonates, lime-water, and the salts of iron, lead, copper, zinc, mercury, and Fowler's solution, are incompatible with the preparations of opium. Notwithstanding this chemical incom- OPIUM. 519 patibility, the metallic salts are frequently given in conjunction with opium, and the systemic effects of both are produced. Astringent vegetables (tannin) are also incompatible ; they limit physiological activity by forming tannate of morphine, which is not readily soluble. In cases of opium-poisoning, if any portion of the drug remain un- absorbed in the stomach, the most prompt and efficient emetic should be used. Apomorphine should be injected subcutaneously, if the patient is unable to swallow ; if conscious, the sulphate of copper may be ad- ministered by the stomach. In a case of opium narcosis which re- sisted ordinary emetics, violent emesis was induced by a solution of bicarbonate of sodium, followed by a solution of tartaric acid. In the absence of other and more active emetics, powdered mustard may be administered — a tablespoonful to a teacupful of warm water. When the opium swallowed is in solution, the stomach-pump should be used if the narcosis is profound. Cold affusion, artificial respiration, when the breathing flags, and faradization of the chest-muscles, are measures of great practical utility. The author has personally witnessed in several cases the excellent effects of faradization, first, in causing such irritation of the surface as to produce reflex excitation of the respi- ratory center ; and, second, inducing contractions of the respiratory muscles. As a peripheral irritant, faradization is more humane and seemly, and also more efficient, than flagellation. The action of opium is antagonized, at least in a part of the sphere of its influence, by belladonna. These agents are opposed as regards their influence on the intra-cranial circulation, on the pupil, on the re- spiratory organs, and on the heart. Opium in lethal doses dilates the arterioles and veins ; belladonna contracts them, and, by energizing the cardiac movements, substitutes an active for a passive congestion. It can not be too strongly insisted on in this connection that belladonna in too great quantity r , or too long in action, exhausts the irritability of the unstriped muscular fiber, and thus induces the very state tohich its administration loas intended to relieve. The state of the pupil, the action of the heart, and the condition of the reflex movements, are the guides to the administration of belladonna in cases of opium narcosis. The smallest quantity of belladonna which will dilate the pupil, raise the tension of the arterial system, deepen the respiration, and re-estab- lish the reflex excitability, should be used. The author has a strong conviction, arising from some painful personal experience, that it is a fatal error to attempt to restore a patient in opium narcosis to com- plete conscious?iess by repeated doses of belladonna. The action of these agents combined is to produce profound sopor, and this is not a condition of danger so long as the pulse, respiration, and reflex move- ments are in good condition. To substitute belladonna narcosis for opium narcosis is only increasing the hazard under which the patient is already struggling. Impatient to afford relief, and assuming that the 520 CEREBRAL SEDATIVES. tendency to sleep must be obviated, the physician too frequently, as the history of many cases plainly shows, repeats the doses of belladonna until its action greatly preponderates, and the irritability of the cardiac ganglia is completely exhausted. The author, therefore, feels himself warranted in repeating that the utility of belladonna consists in its power to maintain the action of the heart, and the respiration, until elimination has taken place, and that even coma is of little importance provided the respiration, circulation, and reflex movements are prop- erly maintained. The hypodermatic injection of atropine is the most efficient and satisfactory method of employing this physiological antagonist. Not more than -j-J-g- of a grain of the sulphate should be administered at a dose, and this may be repeated every fifteen minutes (up to three doses) until dilatation of the pupil, increased power of the cardiac move- ments, deeper respiration, warmth and dryness of the skin, and flush- ing of the face, are produced. No more can be accomplished by the largest doses, and the results of the antagonism must be awaited. Belladonna continues longer in action than opium. In a succeeding chapter, devoted to the consideration of the combined administration of opium and belladonna, or morphine and atropine, the nature and degree of the antagonism will be more fully elaborated. Coffee, with its active principle {caffeine), is also an antagonist to opium. Good results have undoubtedly been obtained by the free use of black coffee, in milder cases of opium narcosis. The unpleasant confusion of mind, and vertigo, which in so many subjects are experi- enced after the subsidence of the effects of a medicinal dose, may some- times be removed by a cup of strong coffee. These cerebral effects may be prevented, or relieved when they occur, by a full dose of bro- mide of potassium. This discovery, if we may dignify so small a mat- ter by so imposing a title, was briefly announced by the author in the first edition of his work on "Hypodermatic Medication," and was afterward more fully set forth in a special memoir by Da Costa, of Philadelphia. Gubler has shown that some of the cerebral effects of opium are antagonized by quinine. Tartar emetic and digitalis also oppose to some extent the action of this remedy on the intra-cranial circulation. Synekgists. — The cerebral and hypnotic effects of opium are pro- moted by alcohol and its derivatives (notably chloral), and, within certain limits, by the mydriatics. The sudorific action of opium is in- creased by ipecacuanha. Physiological Actions. — As opium is a very complex substance, made up of numerous principles which differ remarkably among them- selves, it will conduce to a better understanding of its actions to con- sider, first, opium as a whole, and then follow with some details re- garding its individual constituents. OPIUM. 521 The physiological effects of opium are best studied as respects — 1. Small medicinal doses ; 2. Full medicinal doses ; 3. Lethal doses. 1. The preparations of opium have a disagreeable, bitter, and rather nauseous taste. Dryness of the mouth and fauces, huskiness of voice, and diminution in the sense of taste, occur in a short time after admin- istration of the drug has begun, and continue during the whole period of its influence. To the dryness succeeds a viscid secretion, which contains excrementitious matter having a foul odor. When opium does not produce nausea, the appetite may not be impaired, may be even increased ; but the rule is that the desire for food is lessened by opium. The secretion of mucus, and of the special glandular appara- tus of the gastro-intestinal mucous membrane, is lessened by opium, and hence the digestion and the peristaltic movements are less active. The excretions being thus locked up, dullness and hebetude are expe- rienced, the skin looks muddy, the tongue is coated, and the breath is offensive. When the influence of the opium ceases, it not unfrequent- ly happens that the constipation is succeeded by relaxation of the in- testines, and rather profuse and fetid evacuations, and increased urin- ary discharges, take place. The action of the heart becomes stronger, and the arterial tension rises. When opium agrees, the sense of fatigue vanishes, and muscu- lar movements become more rapid and easy. The face flushes a little, the pupil contracts slightly, the conjunctivae may be somewhat in- jected, and the expression of the eye more brilliant. At this stage the ideas flow more rapidly, but are less sustained and orderly. The ap- preciation of time, the sequence of events, and the sense of moral fit- ness, are diminished. The cerebral excitement is, after a period which varies in different individuals, succeeded by calm, by drowsiness, and sleep when it occurs is usually disturbed by visions and dreams, often of a frightful character. In most subjects, after the sopor has passed off, headache, vertigo, confusion of mind, nausea, constipation, and muscular hebetude, are experienced. 2. When full medicinal doses are administered, the symptoms above described occur in a more intense degree. The stage of cardiac stimulation and of cerebral excitement is of much shorter duration ; and the stage of intoxication and sopor not only comes on more quick- ly, but is much more pronounced. At first the pulse is increased in frequency and the respiratory movements are more rapid ; but the car- diac pulsations soon diminish in number and force, and the respira- tions become sighing in character and more shallow. There is also present decided dryness of the mouth, fauces, and larynx, and swallow- ing becomes somewhat difficult and the voice grows husky. Nausea and vomiting, or at least weight and oppression of the epigastrium, ensue. Confusion of ideas, vertigo, somnolence, are succeeded by deep sleep, contracted pupils, slow and relaxed pulse, slow and snoring 522 CEREBRAL SEDATIVES. respirations, a perspiring skin, and, in many persons, an intense gen- eral pruritus, which, however, is more harassing at the nasal orifices. Persons not habituated to the use of opium usually experience, after a full medicinal dose has expended its force, very distressing sequela?, referable to the cerebro-spinal system. The most important of these after-effects are headache, confusion of mind, vertigo — which is espe- cially severe on assuming the erect posture — nausea, retching and vom- iting, complete anorexia, and constipation. A mild but defined hepa- togenic jaundice not unfrequently occurs, and the urine is tinged with the coloring-matter of the bile. 3. A lethal dose of opium causes but a transient excitement ; the stage of narcosis quickly supervenes, and the functions of animal life are often rather abruptly suspended. The patient soon lapses into a condition of insensibility, with a slow and feeble, or, it may be, rapid and feeble, action of the heart ; slow respiration, shallow and quiet or stertorous ; face at first flushed, but soon becoming shrunken, pallid, and cyanosed ; skin wet ; pupils minutely contracted and insensible to stimulation ; unconsciousness profound, with muscular relaxation and abolition of reflex movements. This state of opium narcosis is with dif- ficulty distinguished from alcohol narcosis, from cerebral haemorrhage — especially in the pons — and from uraemic coma. An attentive con- sideration must be given to all available facts in the history of the case, to the surroundings of the patient, and to the odor of the breath or other excretions, for the symptoms of one of the states above men- tioned may be represented in another, even to the inequality of the pupils, since a case of opium narcosis has been reported in which such inequality existed. There are no characteristic structural alterations produced by opi- um. The brain presents the appearance known as the "wet brain" by pathologists ; the subarachnoid spaces and the ventricles contain an abnormal quantity of serum ; the intra-cranial veins are engorged, and the puneta vasculosa are somewhat more numerous. The right cavi- ties of the heart and the large venous trunks are usually distended with soft coagula. These appearances are largely due to the mode of dying. In consequence of the diminishing frequency of the respir- atory movements, the blood is imperfectly decarbonized, and the capil- lary circulation of the lungs is impeded. The action of the heart being weak and the resistance a fronte increased, it is obvious that venous stasis must take place. It is necessary now to consider somewhat more minutely the na- ture and degree of the action of opium on the different organs and systems of the body. It will save space and avoid repetitions to study these actions in connection with the several principles contained in opium. The Physiological Action of the Alkaloids of Opium. — 1. OPIUM. 523 Morphine. — The peculiar powers of opium are represented chiefly in the morphine which it contains. In opium of good quality the pro- portion of morphine is from ten to fifteen per cent. The actions of the other principles contained in opium differ widely ; and as they all possess some activity, the sum of their effects must so far influence the result that the powers of opium and morphine must vary somewhat in kind as well as in degree. One sixth of a grain of morphine is about equivalent in activity to one grain of average opium. In general terms, it may be stated that morphine differs from opi- um in the following respects : Morphine is less stimulating, less convulsant, and more decidedly hypnotic and anodyne than opium. Morphine constipates less and affects the contractility of the blad- der more than opium. Morphine has less diaphoretic action and produces much more pru- ritus than opium. The physiological action of morphine is best studied as adminis- tered subcutaneously. In a short period — from a few seconds to a few minutes — after the insertion of an ordinary dose — one sixth to one fourth of a grain — under the skin, the symptoms of morphine narco- sis begin. A sense of heat and flushing of the face — after, in most subjects, a very transient pallor — fullness of the head, giddiness, tin- nitus aurium, and frequently nausea, are experienced. Deep-seated epigastric pain is often felt, and loud borborygmi occur. The verti- go may be so considerable as to render walking uncertain and stag- gering, or to render the upright position impossible. Injection of the conjunctivae and contraction of the pupils occur at the same time the cerebral effects are experienced. The lips have a bluish appearance, the mouth and tongue become dry, swallowing is painful, and the voice has a husky tone. When these physiological effects are produced, pain and spasm are relieved, and an indescribable feeling of content takes possession of the mind. A condition of somnolence in many persons, in others of extreme wakefulness, with intense mental activity, is experienced. When sleep occurs, it is usually deep but not calm, the respirations are slow, noisy, and labored. Not unfrequently the sleep is disturbed by dreams and visions, or the individual passes into a somnambulistic state> from which he is aroused with difficulty. The action of the heart is diminished in frequency, but a decided rise takes place in the arterial tension. On ophthalmoscopic examination, a marked increase in the vascularity of the retina, and blurring of the papillae, can be discerned. Soon after a hypodermatic injection has been practiced, itching of the nose, and often of the whole cutaneous surface, is experienced. The skin is at first dry, but, after a time, diaphoresis begins and is sometimes profuse. The relaxation of the skin is coincident with a 524 CEREBRAL SEDATIVES. fall in the arterial tension. The secretions of the mucous surfaces are at first arrested, as well as those of the skin. If the morphine be ad- ministered after a full meal, digestion is suspended for a time. The intestinal movements are also arrested for a short period, and consti- pation is therefore produced ; but, very frequently indeed, no change takes place in the time in which the alvine discharges occur, or in their number. Partly in consequence of the increased action of the skin, the quantity of urine discharged is lessened, and, at the same time, difficulty is encountered in its emission. When the desire is felt, an interval of less or greater duration elapses before the flow begins, and, as the contractile power of the bladder and of the ejaculatory mus- cles is diminished, the discharge is feeble and slow, and the last drops linger in the urethra. With the decline of morphine narcosis a majority of subjects, prob- ably, experience headache, confusion of mind, anorexia, and nausea. When a lethal dose of morphine has been administered by any mode, profound narcotism quickly ensues ; the pulse becomes slow and feeble, or rapid and feeble ; the respirations also become very slow and shallow ; the skin cold and sweating ; the face pale, cyanosed, and ghastly ; the conjunctivae deeply injected ; the pupils minutely con- tracted, and reflex movements entirely abolished. Respiration ceases before the action of the heart, as a rule, but in some instances very sudden death ensues from paralysis of the heart. Half a grain is the smallest dose of morphine which has proved fatal to an adult. Five cases, according to Taylor, have been recorded in which one grain of the muriate caused death. A consideration of the symptoms produced in man by morphine, and the results of experiments on animals, prove that it chiefly affects the cerebro-spinal functions. In the lower animals, the spinal more ; in man, the cerebral more than the spinal functions. Morphine first raises and afterward lessens the action of the heart and arteries ; first stimulates the pneumogastric end-organs and cardiac motor ganglia, and afterward paralyzes both. It causes death chiefly through paral- ysis of the muscles of respiration. 2. Codeine. — According to the author's observations, the codeine of commerce corresponds closely in action to morphine, but is much fee- bler. Four grains of codeine are about equivalent to one grain of morphine. It has anodyne and hypnotic qualities. Codeine produces sleep freer from disturbance, and the after-effects are less disagreeable, than those of morphine. The special direction to the pneumogastric nerve ascribed to it by some observers, seems to the author to exist in nature. 3. JVarcotine. — This alkaloid is singularly inappropriately named. It has but feeble narcotic power. In children considerable doses pro- duce a calmative effect and drowsiness, but these results are not ob- OPIUM. 525 served in adults. Experiments on animals have shown that narcotine is a convulsant. While pigeons are poisoned only by two or three grains of morphine, administered subcutaneously, the same quantity of narcotine causes fatal convulsions. The reverse is true in man. Narcotine is allied in action to berberine, and alkaloids of that group, so far as the effects on man are concerned ; and to thebaine, picro- toxin, strychnine, and brucine, so far as the effects on animals are concerned. 4. JVareeine. — The most contradictory observations have been pub- lished on the action of this principle. By Bernard, Behier, and Eu- lenburg, it is held to possess remarkable hypnotic power, and to be free from stimulating and convulsant action ; by Fronmtiller, Harley, Da Costa, Mitchell, and others, it is considered feeble, if not inert. The physiological actions of narceine, therefore, remain sub judice. Until further researches are made with chemically pure narceine, and by competent observers, it will be safer to give no opinion on the sub- ject of its actions and uses. The other alkaloids of opium are curiosities of chemical and physi- ological research, and may be dismissed in a few words. Cryptopine is in a much greater degree than narceine an hypnotic and anodyne. Thebaine has a strong convulsant action in animals. Various circumstances modify the action of opium. These are chiefly age, sex, idiosyncrasy, habitual use, and certain states of the system, as the presence of pain, uramiia, etc. The extremes of life are relatively more susceptible to the action of opium, and especially is the susceptibility to its action great in early life. Fatal opium narcosis has ensued in a nursing infant whose mother had taken a medicinal dose. A single drop of laudanum has produced lethal effects in a child under six months of age. Women are more easily affected by opium than men, and they are more apt to be thrown into a condition of hysterical excitement than put to sleep. Nausea, vomiting, headache, and depression, much more frequently occur in women than in men. As a rule, therefore — but to this rule there are, of course, numerous exceptions — women are less favorable subjects for the administration of opium than men. More than age or sex is the action of opium influenced by idiosyn- crasy. There are persons so easily affected by it that the minutest quantity will cause uncontrollable vomiting, faintness, vertigo, and alarming prostration. It is never safe to administer morphine hypo- dermatically to such subjects, unless in an extremely small dose. The habitual use of opium diminishes in a remarkable degree the susceptibility to its action. Numerous instances are on record in which a pint or more of laudanum has been taken daily, or several hundred 526 CEREBRAL SEDATIVES. grains of opium, or a scruple of morphine. The author has met with a patient who took a scruple of morphine a day subcutaneously. When opium is given by the stomach, for the relief of a chronic painful disease, to maintain a constant effect increasing doses are necessary. The power of the stomach to absorb opium is doubtless impaired by frequent repetition of the dose, and in consequence of the local action of the drug on the nerves of the stomach. Besides this, the suscep- tibility of the cerebro-spinal system steadily declines. The proof of these statements is afforded by the action of morphine when used sub- cutaneously for long periods. A gradual increase of the dose becomes necessary in order to produce a given physiological effect ; but the in- crease is much slower than when it is administered by the stomach. Great pain lessens the influence of opium upon the centers of con- scious impressions. The quantity in grains is of much less importance than the quantity as measured by the physiological reactions. Uraemia, or the retention in the blood of urinary excrementitious matters, is supposed to increase the narcotic influence of opium ; but some facts, to be hereafter presented, render it probable that the state of uraemia and the influence of opium on the brain are antagonistic. Therapy. — Stomach-pain, whether simply neuralgic (gastralgia), or excited by the presence of food {irritative dyspepsia), or due to ulcer or cancer, is relieved by opium. The preparations of morphine are better than the crude drug, as a rule, in these cases. The endermic application is an excellent mode of procuring relief. The subcutane- ous injection, practiced in the epigastric region, is still more effective. Morphine is frequently combined with bismuth, or zinc, or silver salts, in painful stomach diseases. 3 Bismuthi subcarb., vel subnitrat., 3 iij ; morphinae sulph., gr. j — grs. ij ; pulv. aromat., 3 j. M. Ft. pulv. no. xij. Sig. : A powder in milk before each meal. The following formula is also useful, notwithstanding its unchemical relations : 3 Zinci oxidi, 3 ss ; morphinae sulph., gr. j — grs. ij. M. Ft. pil. no. x. Sig. : One pill, three times a day, before each meal. A half-grain of the oxide of silver may be substituted for the oxide of zinc in the above formula. Inflammatory pain, due to corrosive poisons, to peritonitis, etc., requires opium. When the stomach is irritable, and the symptoms urgent, the best mode of using the remedy is the hypodermatic injec- tion of morphine. Many kinds of nausea and vomiting, stomachal or reflex in origin, are arrested by opium preparations. In vomiting of cerebral origin, or produced by uraemia, or caused by cirrhosis, the use of opium is contraindicated. When vomiting is caused by irritant matters, opium is prescribed after the stomach is emptied. The vomit- ing which accompanies the passage of biliary or renal calculi, dys- menorrhoea, etc., is best relieved by opium. Very severe cases of seasickness, and of the vomiting of pregnancy, may be sometimes OPIUM. 527 arrested when all other means fail, by the subcutaneous use of a mi- nute quantity of morphine (one twentieth to one twelfth of a grain) . Nothing is more common than the prescription of opium in diar- rhoeal diseases, but it is often used without a just appreciation of the conditions requiring it. In acute diarrhoea, caused by irritating ali- ments, such astringent laxatives as rhubarb, or mild salines, should precede the use of opium. When the evacuations are watery, the best results are obtained by a combination of opium with mineral acids, or acetate of lead. In acute dysentery opium is a very im- portant remedy, but it is often injudiciously employed. If there be fever, much tenesmus, and the stools consist of mucus and blood, the exhibition of opium should be postponed until salines have emptied the intestinal canal of its contents, and have depleted the distended vessels. An excellent method of administration, especially when the dysenteric inflammation occupies the rectum, is an enema of starch or milk, or a suppository, containing opium in some soluble form. In chronic dysentery opium is indispensable. It is usually combined with arsenic, or with the salts of silver, copper, or zinc. In the chronic dysentery of malarial origin, the best results are obtained by a combination of arsenic and opium, according to a formula already given ; in that form which succeeds to the acute disease, opium and sulphate of copper, or zinc, or nitrate of silver, or vegetable astrin- gents. Nothing can be more satisfactory than the treatment of cholera- morbus by the hypodermatic injection of morphine. It is always desirable to secure the expulsion of irritating matters before resorting to opiates. For an ordinary case of cholera-morbus from one twelfth to one sixth of a grain of morphine suffices. In true cholera the utility of opium is most evident in the preliminary diarrhoea, but is entirely without avail in the stage of collapse. Mischief not unfre- quently results from its use, for patients emerging from the condition of collapse are either directly narcotized by the opium which had lain unabsorbed in the stomach, or the cerebral symptoms of the secondary fever are greatly intensified by it. In cholera infantum opium must be used with caution, if not avoided. The subjects of this malady are easily narcotized, and the nervous system — an unknown morbid state of which bears some close relation to the gastro-intestinal dis- order — is rendered so irritable by opium that the symptoms are ag- gravated by it. The following formula embodies a truth of great practical impor- tance : As a rule, opium does harm in all gastro-intestinal maladies in which there is a deficiency in the proper secretion, or a suspension of the functions, of the liver and kidneys. Opium gives a degree and kind of relief in hepatic, renal, and saturnine colic, which no other remedy or combination of remedies 528 CEREBRAL SEDATIVES. affords. The most prompt and effective form in which the remedy can be administered is the hypodermatic injection of morphine. This relieves the pain, and relaxes the spasm of the affected tube, and at the same time checks the depressing vomiting which attends these cases. The quantity of morphine required will vary from one fourth to one half a grain. As the effect is immediate, the most prudent practice consists in the administration of a small quantity (one sixth to one eighth of a grain) for the first dose, in order to test the physi- ological capabilities of the patient, and following this in fifteen min- utes with a dose of similar size if the first is well borne and the pain persist. Opium, in small doses, is a valuable tonic to a weak and dilated heart. When administered simultaneously with digitalis, it obviates one of the dangers which may be caused by that agent. In the so- called passive haemorrhages , in which not only is the blood altered in quality but the tension is low, small doses of opium sustain the powers of life, and by increasing the arterial tension lessen the transudation through the vessel-walls. Under these circumstances, the dose of opium should not as a rule exceed five minims of the tinctures, and it should generally be given in combination with ergot, digitalis, tannic and gallic acids, acetate of lead, etc. The important observation was made by Bernard, and afterward illustrated and confirmed by Kussbaum, that the hypodermatic injec- tion of morphine, administered before the inhalation begins, prolongs the stage of chloroform narcosis with a less quantity of the anaesthetic, diminishes the danger of cardiac paralysis, and prevents the after-nau- sea and depression. Opium is the most important agent which we possess in the treat- ment of various inflammations. Its efficacy depends upon several fac- tors : it relieves pain, quiets restlessness, and thus removes from the inflammatory process one of its most important elements, viz., an irri- table and paretic state of the nerves of the affected part. Besides these effects, opium raises the tonicity of the vessels, helps to maintain the continuity of the blood-current, and hinders the migration of the white corpuscles of the blood. It is especially in inflammations of the serous membranes that its highest utility is manifest, e. g., pleuritis, peritonitis, arachnitis. Good reasons exist for believing that the hy- podermatic injection of morphine will sometimes cut short (jugulate) these maladies, if administered just at their onset. If the period for obtaining such a fortunate result has passed, the course and duration of these diseases can be greatly modified by the judicious use of opium. The quantity of opium required will be determined by the effect ; the pain should be relieved, the pupils somewhat contracted. A full dose should be administered at the beginning of treatment (two to three grains of opium — a half grain of morphine), and a given physiological OPIUM. 529 effect be maintained by the regular use of smaller doses. Pain is probably the surest guide, for the existence of pain indicates that de- cided opium narcosis has not been attained. In peritonitis, whether puerperal, traumatic, or the extension of intestinal inflammation, no fact of therapeutics is better established than the curative power of opium. Besides its immediate influence over the inflammatory process, its indirect action, in maintaining the necessary quietude of the intestines, is of the greatest service. In arachnitis, pachymeningitis, basilar meningitis, there are clinical facts which tend to show that small doses of some opiate preparation really accomplish more than any other remedies. The author is convinced that we possess no means of treatment of cerebrospinal meningitis so effective as the opiate treatment. The same rule as to the quantity required, as that given for peritonitis, should be observed : that quan- tity of opium should be administered which will relieve the pains and rigidity. The best results are obtained by the hypodermatic injection of morphine. When effusion takes place, and stupor and coma ensue, the utility of opium is ended. In parenchymatous inflammations, experience has shown, opium is much less useful. When pain is a prominent symptom, it can be em- ployed to relieve it ; in small, stimulant doses, it may be given to maintain the action of the heart. In pneumonia opium is a remedy of very doubtful utility. Its narcotic action certainly disposes to pul- monary congestion, although it may be cautiously used to allay pain and moderate cough. Although this was the general professional opinion, and is now largely held, there are those who entertain very different views regarding the utility of opium in pneumonia. Thus, Prof. A. L. Loomis, of New York, maintains that the disease may be aborted, or at least decidedly modified in severity, by the subcutaneous injection of morphine in the first stage (congestion) of this disease. In fevers — typhoid, typhus, and eruptive fevers — opium was for- merly much more frequently prescribed than at present. The cold baths, antipyretics, and more favorable hygienic influences, have less- ened the violence and diminished the mortality from fevers. The maniacal excitement and the low, muttering delirium are not so fre- quently observed now as formerly, and hence the use of opium in these affections has greatly declined. The discovery of chloral has also di- minished the use of opium as an hypnotic. Nevertheless, when there is much restlessness, wakefulness, subsultus, and delirium, opium may render important service. When the delirium is of the low, mutter- ing kind, a small quantity of moiphine (one eighth to one sixth of a grain) may suffice to procure quiet and refreshing sleep. When the delirium is violent, combination of tartar-emetic with opium, on the plan of Graves, may have a very happy effect. Or opium may be combined with belladonna, or chloral — the former when the condition 34 530 CEREBRAL SEDATIVES. is one of great depression, the latter when the delirium and wakeful- ness are excited in character. In measles and scarlet fever, when there is a condition of profound depression, the eruption being tardy in making its appearance, and is dusky in hue and ill-defined, beneficial results are experienced from the use of opium, especially when com- bined with camphor. A threatened paroxysm of intermittent fever may be aborted by the hypodermatic injection of morphine (one fourth of a grain). This practice has a high degree of importance in the pernicious intermit- tens, when time is not afforded for an effective use of quinine. The fe- brile heat of intermittent and remittent fevers may be diminished, and the sweating stage induced earlier, by the use of opium in moderate doses (ten minims of the deodorized tincture every two, three, or four hours). The addition of morphine to quinine enables the latter to be better borne by the stomach, counteracts some of its unpleasant effects on the brain, and increases its therapeutical power. When no contra- indication to the use of morphine exists, it is good practice to combine it with quinine in the treatment of intermittent and remittent fevers. Narcotine has decided antiperiodic power, and may be given as a substitute for quinine when reasons exist to prevent the use of the lat- ter. From five to ten grains of pure narcotine may be administered. As an antiperiodic it ranks after arsenic, salicine, and even apiol. As an hypnotic opium is very frequently used in affections of the nervous system. The stimulant properties of crude opium, or its offi- cial preparations, render it less serviceable than morphine in the group of cases generally requiring an hypnotic. There can be no doubt that remarkable curative results have followed the hypodermatic injection of morphine in acute mania. The following are the indica- tions for the use of morphine in mental disorders : prolonged wakeful- ness, maniacal excitement, persistent refusal of food, drink, or medi- cine, destructive and suicidal tendencies. As respects individual subjects, the state of the arterial tension furnishes a guide to the use of morphine. If the tension of the arterial system is low, a small dose is required. When the pulse is quick, and the arterial tension high, a large dose of morphine, by over-excitation, causes paresis of the sym- pathetic, and thus reduces action, an indication for the full influence of the agent. Large doses of morphine, when given subcutaneously, require the utmost circumspection in maniacal cases, especially in obese and aged subjects. Besides acute mania, excellent results have followed from the use of morphine in lypemania (Krafft-Ebing, Voi- sin), in chronic mania, and melancholia. Probably the best effects have been witnessed from opium in melancholia. In this mental dis- order, which is a condition of depression, the best form for the admin- istration of opium is the tincture, and the dose required is the stimu- lant and not the narcotic dose. The author is impelled to add the OPIUM. 531 caution so well expressed in the following words by Maudsley : " It will be well to have in mind that neither opium by the mouth, nor morphine hypodermically injected, will always quench the fury of acute mania, and that successive injections of morphine, followed by brief snatches of fitful sleep, have been followed also by fatal collapse." It was formerly held that large and increasing doses of opium were necessary for the cure of delirium tremens, the theory being enter- tained that to procure sleep was to insure recovery. It is now known that to re-establish digestion and to support the powers of life by suit- able nutrients are in a large proportion of cases the only means needed to quiet delirium and to cause sleep. Opium, if used at all, must be given cautiously. Chloral has to a large extent taken its place as an hypnotic in this disease, but cases are not unfrequently met with in which morphine agrees better, and is more effective in inducing quiet. Some cases of sunstroke, coup de soleil, or "thermic fever," are rapidly cured by the hypodermatic injection of morphine. When the patient is able to swallow, good effects follow the conjoined admin- istration of tincture of opium and brandy. The cases benefited by this treatment are characterized by pallor of the face and weakness of the heart — heat exhaustion. Epilepsy and epileptiform seizures may be sometimes prevented by the timely administration of morphine hypodermatically. This treat- ment is best adapted to epilepsy, the attacks of which occur at night, to petit maly and to convulsive tic. It is improper in epileptoid seiz- ures due to tumor or other coarse organic lesion of the brain. In suitable cases, this treatment procures most decided amelioration in the condition of the patient, but may induce the opium habit. The remarkable fact has been demonstrated by Loomis, of New York, that we have in the hypodermatic injection of morphine the most important agent for the cure of urcemic convulsions, puerperal and non-puerperal. It is true this mode of treatment had been origi- nally practiced by Scanzoni, but Loomis has, more especially, drawn attention to its real power and utility. " The most uniform effect of morphine so administered is, first, to arrest muscular spasms by coun- teracting the effect of the uraemic poison on the nerve-centers ; second, to establish profuse diaphoresis ; third, to facilitate the action of ca- thartics and diuretics, especially the diuretic action of digitalis." In chorea Trousseau has carried the administration of morphine to an extraordinary extent. He restricts its use to severe cases, which appear to have a singular insusceptibility to the action of opium even in enormous doses. When the jactitations are incessant, preventing sleep, or persisting in spite of sleep, the utility of morphine is very great. It is most effective when combined with chloral. In these se- vere cases of chorea, the only limit to the quantity of morphine is the 532 CEREBRAL SEDATIVES. effect produced. It is evident, from the experiences of Trousseau, that very large doses are required, and that curative effects are thus obtained to which small doses are entirely inadequate. The subcu- taneous method is more efficient than the stomach administration. In tetanus and hydrophobia the use of morphine has been chiefly palliative. M. Demarquay has, however, applied morphine, by deep injection into the tetanized muscles, with greater success than hereto- fore. He carries the needle deeply into the tetanized muscles, and, if possible, to the point of entrance of the nerves. He injects in this way the masseters, the sterno-cleido -mastoid, the neck and sacro-lum- bar muscles, etc. The relaxation of the muscles of mastication thus induced permitted the nourishment of the patients. Of three cases thus treated during the siege of Paris two recovered and one died, but the death was due to pyaemia and not to tetanus. The most important uses of opium and its various preparations are in the relief of pain. In surgical practice its administration is indis- pensable to prevent or mitigate shock, to quiet pain, and to check in- flammation. To particularize on these points would require an epit- ome of surgery for illustration. Before the administration of chloro- form, morphine should be injected hypodermatically, to diminish the dangers of the inhalation and to secure relief to the after-pain of the surgical operation. Nothing is more universal in surgical practice than the administration of an opiate after an operation of any magni- tude, for the objects above named. The most signal service is rendered by opium and its preparations in the various neuralgias. The most effective mode of administration is by subcutaneous injection, and the remedy should be inserted in the neighborhood of the affected nerve, notwithstanding that relief is af- forded by the injection at any point. In tic- douloureux, brachialgia, cardialgia, gastralgia, hepatalgia, nephralgia, sciatica, and pelvic neu- ralgias, immediate relief is afforded by this remedy, and the relief is not temporary and palliative merely, but curative in numerous instances. It appears to be especially curative in sciatica. It is a remarkable fact that morphine inserted under the skin, and especially in the neighbor- hood of affected nerves, exerts a curative power which it does not at all have when administered by the stomach. An efficient method of using morphine in the treatment of neuralgise, according to Brown-Sequard, consists in applying it in a finely-divided state to the derma, denuded by a blister. Laf argue proposed the method of inoculation, which con- sists in inserting morphine into the skin by means of a lancet-puncture. These clumsy and painful processes are by no means equal to the hypo- dermatic method. The enchanting sense of relief to suffering wrought by opiates, and especially by the subcutaneous use of morphine, leads to the morphine - habit. It is a singular fact that in these cases the pains which were OPIUM. 533 cured by the remedy return when it is withdrawn, and other painful sensations appear of an even more distressing kind. In practicing the hypodermatic method for a long period in severe cases of neuralgia, the utmost care should be used to avoid the morphine-habit. In the neuroses of the respiratory organs, great relief is often af- forded by the use of opium in some of its forms. No remedial agent' will so quickly cut short a paroxysm of asthma as the hypodermatic use of morphine. The paroxysms of difficult breathing which occur in emphysema are also readily relieved in the same way. But there is great danger of establishing the opium-habit in these chronic cases. In an allied disease — hay-fever, hay-asthma, or autumnal catarrh — the hypodermatic use of morphine is quite as effective as in spasmodic asthma. An incipient catarrh may be aborted by a full dose of Do- ver's powder, taken at the very outset of the inflammation. Morphine and quinine combined are rather more effective than Dover's powder in these cases. Opium, or some of its preparations, enter into the com- position of expectorant mixtures to allay cough. The hypodermatic injection of morphine has been shown to possess a high degree of utility in cases of dilated heart with difficult breath- ing, and general oedema. The eighth to the sixth of a grain suffices for this purpose. The effect it has is to quiet and regulate the action of the heart, to allay the distress of breathing, and to permit rest and sleep in the recumbent position. An occasional dose only is necessary (two or three times a week). Opium is a very important addition to our resources in the treat- ment of diabetes. It must be given in considerable doses, as Pavy has shown. From six to twelve grains a day are necessary, in order to pro- duce a decided impression. It checks the bulimia — the inordinate ap- petite — allays thirst, diminishes the flow of urine and the excretion of sugar, and, probably, arrests or prevents the changes in the nervous system which accompany or are causative of this disease. Although many cases are decidedly ameliorated, it can not be said that any have been cured by opium. Codeine, an alkaloid of opium, seems to be more effective in this disease than the crude opium or any of its prepa- rations. It must be given in full doses. Besides checking the waste, it apparently exercises an influence over the central nerve-changes, and thus has a curative action as well as merely palliative. External Uses of Opium. — A solution of morphine in distilled water is an excellent astringent anodyne in conjunctivitis, and, com- bined with atropine, in iritis. ££ Morphinae sulph., grs. iv — grs. viij ; aquae destil., § j.

Local inflammatory swellings, painful in character, can be relieved somewhat by poultices containing laudanum. Frictions with laudanum are serviceable in lumbago, sciatica, myalgia, and similar superficial painful affections. An infusion of opium ( 3 j — Oj), applied hot, is an excellent application to inflamed joints, inflamed testicle, etc. On the Combined Uses of Opium and Belladonna, Morphine, and Atropine. — The conjoined use of these agents is so important a subject from the point of view of practical therapeutics, that the author purposes to consider it under this head. Although a physiological an- tagonism as respects a part of their action unquestionably exists, it does not extend throughout their whole range of influence in the organism. The balance of actions furthermore produces results which neither is capable of singly. Hence the importance of a more direct presentation of these points than has been heretofore given. Both act on the brain, atropine causing delirium, hallucinations, and disturbed sleep ; morphine producing stupor, somnolence, hebetude of mind. Both relieve pain, but this effect is much greater in the case of morphine. Both produce disorders of motility, staggering, difficulty of co-ordination of muscular movements, vertigo, confusion of mind, and headache. The reciprocal influence exerted upon each other, when they are administered together, modifies in a remarkable manner their physiological effects. Morphine corrects the illusions and phantasms produced by atro- pine. In small doses (e. g., one ninety-sixth of a grain) atropine in- creases the hypnotic power of morphine, with the result of causing a less disturbed and more nearly normal sleep than is produced by mor- phine alone. If, however, the quantity of atropine be in excess of what is necessary to establish the physiological balance in the cere- brum, it overrides the action of morphine and asserts its own peculiar power of inducing phantasms, illusions, and hallucinations. The pain-relieving power of morphine is rather increased than di- minished by atropine. The disorders of motility are enhanced by the mutual reactions of the two agents. The after-headache, vertigo, nausea, and depression of the heart's action caused by morphine, are to a large extent prevented by the conjoined administration of atro- pine. When a large quantity of opium, or morphine, is given by any of the modes of administration, its immediate depressing effects are counteracted by the simultaneous use of belladonna or atropine. Morphine produces contraction of the pupil, and a tetanic condition (according to Graefe) of the muscle of accommodation ; atropine causes dilatation of the pupil and contraction of the ciliary muscle. When used together these effects may be precisely balanced. It re- quires but a minute quantity of atropine to overcome the action of OPIUM. 535 morphine on the pupil. When these effects on the pupil are balanced, it does not follow that the muscle of accommodation is in a normal condition, for visual defects remain. Morphine prevents the contrac- tion of the arterioles produced by atropine, and, as a necessary conse- quence, the subsequent relaxation of the muscular fiber. Morphine depresses the action of the lungs ; atropine is a powerful respiratory stimulant. Morphine produces pallor of the surface, and reduces the external temperature ; atropine causes redness and injec- tion of the skin, and elevation of the body-heat. In some experiments the author ascertained that while atropine alone raised the pulse to 105 from 72, atropine and morphine combined depressed the pulse of the same subject to 60. Both morphine and atropine produce dryness of the mucous mem- brane of the mouth and fauces. Morphine suspends, and atropine in- creases, the peristaltic movements. The sickness and nausea caused by morphine are, to a considerable extent, lessened or prevented by atropine. Morphine lessens and atropine increases the functional activity of the kidneys ; on the skin their effects are opposed ; hence, when used in combination, the urinary secretion is rather increased than dimin- ished by them. Both produce dysuria. Theeapeutical Applications of Opium asd Belladoxxa. — Whenever opium is used to relieve pain, to procure sleep, to relax spasm — there being no inflammatory action present — belladonna should be combined with it, unless some contraindication should exist to the action of the latter. This formulated expression is more espe- cially applicable to the hypodermatic use of morphine. In the various psychical disorders, in which the general condition is sthenic, opium or morphine should be used alone. When power is deficient, the forces depressed, the temperature rather below than above the normal, belladonna or atropine should be combined with the opium or morphine. For the relief of insomnia the combined action of these agents is much more effective than either singly. The pro- portion in which the alkaloids should be used is about as follows : yJ-q — j-J-g- of a grain of atropine to -^ and £ of a grain of. morphine. In the various convulsive disorders in which opium or morphine may be used, especially hypodermatically, atropine should be combined with it. The neuralgice are best treated by morphine and atropine com- bined, for the following reasons : the combination is more effective, the after-unpleasant effects of either are prevented to a considerable extent. The neuroses of the respiratory organs, of the abdominal viscera, etc., are, as a rule, more successfully treated by morphine and atropine in combination, than by either separately. 536 CEREBRAL SEDATIVES. In surgical diseases and operations of various kinds, the combina- tion of morphine and atropine has most important and varied applica- tions, among which may be enumerated : to render safer and to pro- long ether or chloroform narcosis ; to prevent or relieve shock; to save suffering ; to relax muscles / to facilitate operative procedures. The combined administration of morphine and atropine is of the greatest service in obstetric practice : to relieve the teasing pains of the first stage / to procure sleep in the course of an exhausting labor ; to quiet after-pains ; to facilitate the performance of various obstetric operations ; to arrest pmer per al convulsions.

Physiological Actions. — Hop is an aromatic stomachic tonic, and as such promotes the appetite and digestive power. It is slightly astringent also. The action of the heart is somewht increased, the cutaneous circulation excited, and diaphoresis produced. In a very slight degree, hop first causes cerebral excitement, fol- lowed by calm and a disposition to sleep. Experience has shown that it possesses some anaphrodisiac property, and lessens the functional activity of the testes and the apparatus of erection. Therapy. — As a stomachic tonic hop is quite as serviceable as many more rare and costly medicines. It is useful in atonic dyspepsia, simple flatulent colic, and mild diarrhoeas. The power of a hop pillow to quiet the mind and to induce sleep seems to be well established, but its influence is, doubtless, largely due to imagination and the association of ideas. The tincture of lupuline and the oleo-resin are useful remedies in mild cases of delirium tremens. They serve a double purpose — as a stomachic tonic and cerebral seda- tive. A combination of fluid extract or tincture of lupuline and tinc- ture of capsicum is probably the best substitute for alcoholic stimulants, when the habit of their use is to be discontinued. t> Ext. lupulinre fluid., tinct. capsici, aa § j.

Nocturnal seminal losses may be reduced in frequency by the use of lupuline, of which the best preparation for this purpose is the oleo- resin. Chordee is said to be prevented by the use of lupuline, but the author has been quite disappointed in his attempts to relieve this state by this remedy. A hop poultice or bag is a domestic remedy for internal pains and inflammation, especially of the abdominal organs. A quantity of hops is sewed into a muslin bag, dipped in hot water, and then laid over the affected region. It forms a light fomentation, which owes its virtues rather to the heat and moisture than to the anodyne qualities of the hops. Lactucarium. — Lactucarium.

Physiological Action, and Therapy. — The soporific quality of lettuce is known to all who eat this vegetable. Notwithstanding this universal experience, careful experiments have shown that lactucarium possesses a very feeble hypnotic quality, if it be not entirely inert. It is only used as a substitute for opium and its alkaloids when these disagree. The sirup of lactucarium is prescribed to relieve cough, but it is better employed as a vehicle for more powerful agents of the class of expectorants. Bromides. — Ammonii Bromidum.

Antagonists and Incompatibles. — Acids, acidulous and metallic salts are incompatible with bromides of ammonium and potassium, and nitrous ether with the former. The physiological actions of the bro- mides are antagonized by cold, digitalis, belladonna, ergot, and other agents which energize the vaso-motor nervous system. Synergists.— Opium, chloral, and remedies belonging to the same group, promote the action of the bromides on the brain ; and aconite, veratrum viride, gelsemium, etc., increase the depressing effect of the bromides on the circulatory system. Physiological Actions. — The taste of a bromide is bitter and saline. In a short time after it is swallowed, the characteristic taste returns to the mouth, owing to the outward diffusion of a portion of that administered. The tactile sense of the fauces, as also the muscu- lar movements in the act of swallowing, are diminished by long-con- tinued use of the bromides. Sixty grains of the bromide of potassium or sodium, and a less quantity of the ammonium salt, will in some persons produce slight nausea and diarrhoea ; in others, a sense of coolness in the epigastric region ; but in many, provided the salt is properly diluted, no effect on the stomach. Gastric catarrh is undoubtedly one of the evil results which may follow the protracted administration of the bromides in considerable doses. These are diffusible substances, and hence pass quickly into the blood. When large doses are administered, it is probable that no inconsiderable portion escapes absorption, for they can be detected in the intestinal mucus and in the faeces. Very obvious effects on the action of the heart, on the respiration, and on the animal temperature, are produced by the bromides if admin- istered in considerable quantity. These functions are depressed, but the depression is much less evident as to temperature ; hence, in order to determine this result, most careful observations are necessary. The author has ascertained that two drachms of bromide of potassium will lower the temperature in a healthy adult from one fifth to one half a degree ; the respirations from two to five, and the pulse from ten to 540 CEREBRAL SEDATIVES. twenty beats per minute. These effects are more pronounced in ani- mals, as ascertained by the administration of lethal doses. In man the number of the cardiac pulsations is not only reduced, but their force is diminished, and the tension of the arterial system is lowered. A transient excitement, intoxication, giddiness, in some persons an anxious mental state, are produced by one or several large doses. As a rule, slight somnolence, and sounder and more refreshing sleep result, provided no disturbing element intervenes. The pupil is not affected in its size and sensibility to luminous impressions in an adult man by a dose of one hundred and twenty grains. When long continued, the hypnotic effect is much more pronounced, and a constant drowsiness is experienced. The sensibility to pain, but especially the sensibility to tactile impressions, is lowered by the bromides at all accessible points of the mucous membrane, and of the skin — notably of the plan- tar surfaces of the hand and foot. The diminution of the sensibility of the mucous membranes is in part due to a local action of the salt as it is being eliminated. Motility is impaired by the long-continued use of the bromides in man, and in animals paralysis of the muscles ensues. If injected into the tissues of a limb, paralysis of motion and sensibility begins in that member. In man the impaired motility is probably due to other fac- tors as well as to the action of the bromides on the muscular tissue, viz., to the cutaneous anaesthesia, and to an anaemia of the co-ordi- nating centers, in consequence of which their functional power is lowered. A very notable effect of the bromides — chiefly bromide of potas- sium — is the diminution of the sexual feeling and of the power of erections produced by it. This fact has been established by abundant clinical evidence. The result is not, however, produced with equal facility in all cases, and considerable doses are necessary in any case. Prolonged administration of the bromides develops a peculiar state, to which the term bromism is applied. This condition of chronic poi- soning differs from the effects of a few medicinal doses in the extent and intensity, but not in the character, of the symptoms. The follow- ing were the symptoms of bromism, as observed in an epileptic boy, to whom two drachms of the bromide of potassium had been administered daily for a month : extreme pallor and anaemia, dilated pupils, acne on face, forehead, and shoulders ; a fetid, bromine breath ; slow and feeble action of the heart ; breathlessness, and quickened pulse on slight exertion ; cool hands and feet ; a general subjective sense of coldness ; movements in walking tremulous and uncertain ; diminu- tion of the tactile sensibility of both cutaneous and mucous surfaces ; fauces dry, and the reflex movements sluggish ; swallowing somewhat difficult ; antaphrodisia and complete relaxation of the genitals ; mind weak, manifested in silly conduct and unmeaning laughter. BROMIDES. 541 Various mental symptoms are in some subjects produced by the long-continued use of the bromides. Weakness of mind, without per- version of intellection, is a very constant result of the continued use of large doses. Headache, confusion of mind, and a sort of intoxica- tion, had long ago been observed to follow the use of the bromide of potassium in even moderate doses (Puche). A form of mental de- rangement, with hallucinations of a melancholic character, has been observed by Hammond and others, and in a few instances a pleasura- ble intoxication, with exalted ideas, has been produced. The pallor and anaemia of bromism are due to several causes : to the diminished action of the heart ; slowness of the capillary circula- tion, and consequent interference in the metamorphosis of tissue ; de- rangement of digestion and assimilation in consequence of gastric ca- tarrh ; and diminished blood-supply to the cerebro -spinal axis. The disorders of voluntary movement, the uncertain gait, the apparent defects of co-ordination, are variously explained ; but, they are doubt- less made up of several factors, of which the cutaneous anaesthesia is the most influential. The bromides possess the power to destroy or impair the irritability of the motor and sensory nerves, and the con- tractility of muscle, and to these effects must be attributed in part the disorders of voluntary movement noted above. It is very obvious that the bromides depress certain organic func- tions : they diminish the action of the heart, lower the animal tem- perature, and lessen the blood-supply to various organs. These re- sults can only be accomplished by a sedative influence on the sympa- thetic system. Some very accurate observers have maintained that in this action lies all of the physiological power of the bromides (Rey- nolds, Amory). Effects of the Bromides compared. — There is a general corre- spondence in the actions of the different bromides. As respects their influence on the pulse, body-heat, and respiration, the author's com- parative experiments have demonstrated that these agents stand to each other in the following order : bromide of sodium, bromide of lithium, bromide of potassium, bromide of ammonium. Very notable differences exist between the bromide of ammonium and the others, due, undoubtedly, to the character of the base. The author's experiments on animals further demonstrated the fol- lowing : bromide of potassium possesses the most toxic power, and bromide of sodium the least. The bromide of lithium is first, the bromide of sodium second, and the bromide of potassium third, in hypnotic power. As respects the influence of these agents severally on the reflex faculty of the spinal cord, it may be stated that none of them possess the power to abolish the reflex faculty except when ad- ministered in sufficient quantity to produce lethal effects. Consid- ered from this point of view, the bromides may be grouped as fol- 542 CEREBRAL SEDATIVES. lows : bromide of ammonium, bromide of potassium, bromide of lith- ium, bromide of sodium. The elimination of the bromides takes place through the mucous membrane of fauces, intestinal canal, and bronchi, through the skin, but chiefly by the kidneys. The rate of elimination varies, but is usually slow, several days being occupied in its diffusion outwardly from the blood. Therapy. — In some kinds of vomiting the bromides are most ser- viceable. The form of vomiting, to the treatment of which they are adapted, is that of cerebral origin ; e. g., the vomiting of cerebral con- gestion, sea-sickness, the vomiting of pregnancy, etc- They are con- traindicated in all cases of vomiting due to primary gastric disturbance. Remarkable improvement not unfrequently results from the use of bromide of potassium in cholera infantum. It is difficult to define the precise conditions under which this agent is successful ; but, accord- ing to the author's observation, it is useless, if not injurious, when de- fective alimentation is the cause of the attacks, and is serviceable just in proportion to the degree in which an irritable state of the nervous system dominates the gastro-enteric disturbance. When the cause of the attacks is heat, or reflex irritation of the fifth pair, as in teething, or cerebral congestion, very excellent results are obtained from the use of the bromide of potassium. ^ Potassii bromidi, 3 ij ; syrup, simplicis, § ss ; aquae menthae pip., 5 jss.

Increased action of the heart (hyperkinesis) due to irritation of the sympathetic, as, for example, such as occurs in exophthalmic goitre, is calmed by the bromides. The irregular and too frequent action of the heart, occurring in hysterical subjects of plethoric constitution, is generally relieved in the same way ; but the bromides are contraindi- cated in all cases dependent on anaemia. Disturbed action (overac- tion) of the heart, with cerebral hyperaemia, is frequently most ad- vantageously treated by a combination of digitalis and a bromide : ty Inf. digitalis, § iv ; potassii bromidi, f ss — § j. M. Sig. : A table- spoonfid morning and evening. Da Costa has, in several publications, strongly urged the use of the bromide of ammonium in acute rheumatism. Doubtless, other bromides (potassium, sodium, lithium) would be as effective, and are certainly much less disagreeable. The author has used the bromide of lithium with considerable apparent success, in subacute rheumatism, in rheumatic gout, and to remove the stiffness and nodosities of joints re- maining after attacks of the above-named rheumatic affections. The BROMIDES. 543 wakefulness, delirium, and hyperpyrexia, which sometimes complicate rheumatism and gout, are best treated by bromide of lithium, pain being relieved by morphine if necessary. It has been stated that the bromides, especially bromide of ammo- nium, diminish the deposition and hasten the retrograde metamorphosis of the fat in obesity. Undoubtedly these agents increase waste, but they do so, chiefly, in consequence of a severe gastric catarrh which they set up. Rabuteau has proposed the use of the bromides as eliminating agents in cases of mercurial, cupric, or saturnine poisoning. These agents, more efficiently than the iodides, combine with the deposited minerals, convert them into soluble combinations, and thus cause their elimination. The best results are probably obtained by a combination of the bromide and iodide of potassium. The most important therapeutical applications of the bromides of potassium, sodium, lithium, etc., are in the treatment of cerebral dis- orders from overaction. The bromides acting on the heart slow its movements, and, on the vaso-motor nerves, diminish the intra-cranial blood-supply. The best results are obtained in the treatment of cases in which there is no ansemia on the one hand, or inflammatory re- action on the other ; cases in which the intra-cranial blood-supply is in excess, because the vaso-motor regulating centers are wanting in activity. The most typical representation of this condition is seen in wakefulness from cerebral overwork. No clinical fact is more con- spicuous than that the bromide of potassium will relieve wakefulness of this kind. The hypnotic action of the bromides is not a certain action like that of chloral, nor like that of morphine under appropriate conditions ; considerable mental excitement and an active cerebral congestion may entirely prevent the hypnotic effect. Wakefulness from mental worry, fatigue, unrest of the peripheral nerves (fidgets), and similar causes, will generally be relieved by the bromides. For this purpose a cumulative action is generally desirable, effected by giv- ing a dose of fifteen grains before each meal, and one of thirty grains on retiring. The manner in which the hypnotic action of the bromides is limited by certain states of the intra-cranial circulation is well ex- hibited in delirium tremens. In the condition of nervous excitement and wakefulness which precedes the delirium, and which is known as " horrors," the action of the bromide is most satisfactory ; it quiets the restlessness and induces sleep. For this purpose considerable doses are necessary — a drachm every four to six hours. When, how- ever, delirium tremens is fully developed, this remedy is much less efficient, and frequently fails altogether to produce sleep. It is more serviceable in the first than in subsequent attacks of horrors, and its utility diminishes as the structural alterations of chronic alcoholismus increase. 544 CEREBRAL SEDATIVES. In some cases of maniacal excitement the bromides produce excel- lent effects, but they very frequently fail without apparent reason. In acute mania accompanied by heat of head, injected conjunctivae, and restlessness, refreshing sleep may follow the administration of one full dose ; but the remedy fails more frequently than it succeeds. In puerperal mania of the sthenic form, with rather quick and full pulse, hot head, and injected conjunctivae, the author has witnessed excellent results from the use of the bromide of potassium ; but it has rather increased the delusions and the depression when the type of the case was melancholic, with systemic weakness and anaemia. A similar ex- perience has been had in the use of the bromides in hypochondriasis and melancholia. These forms of mental trouble are most usually accompanied by bodily weakness, and are rather increased by the use of the bromides ; but it occasionally happens that these agents give an amount of relief afforded by no other drug or combination of drugs. It is impossible to indicate, in the present state of our knowl- edge, the particular cases in which the bromides may be serviceable, but the author ventures to express the opinion that the state of the intra-cranial circulation, which may be ascertained on ophthalmoscopic examination, will furnish the true guide. It need hardly be ob- served that the bromides are useless when wakefulness is dependent on pain. Some kinds of neuralgia are much benefited by the bromides. The congestive form of migraine, or sick-headache, is generally quickly dispelled by one or more full doses. The form of migraine in which it acts almost as a specific is that characterized by a flushed face, throbbing temples, injected conjunctivae, eyes intolerant of light. The bromides often give great relief in the fugitive nerve-pain of hysteri- cal women ; but they are quite ineffectual in neuralgia fixed in a nerve, as, for example, in trigeminal neuralgia, sciatica, etc. The bromide of potassium is often quite successful in ovarian neuralgia, and in the nervous unrest which grows out of ungratified sexual in- stinct in men and women. Very remarkable results have been obtained by the use of large doses of bromide of potassium in tetanus. H. C. Wood gives a tabular statement of fifteen cases which he has collected, in which the bromide of potassium was the chief or the only agent used, and of these but two died. No results equal to this have been achieved by any other agent, not even by Calabar bean. In order to succeed with this remedy it must be given in large doses ( 3 j every three or four hours). A combination with chloral is also highly effective, but these agents exert a powerfully depressing action on the heart. Cases of strychnine-poisoning have been reported cured by full doses of the bromide of potassium. One case is narrated by Dr. Gillespie in which three grains of strychnine were taken, and the lethal BROMIDES. 545 effects were obviated by one ounce of bromide of potassium in divided doses. No therapeutical fact is better established than the influence of bromide of potassium over epilepsy and epileptiform seizures. But the curative power of this agent in epilepsy has numerous limitations. It has been well ascertained that bromide of potassium is most valu- able in those cases of epilepsy characterized by frequent and violent convulsive seizures. Epileptiform attacks, dependent on the presence of a tumor or other coarse organic lesion of the brain, are usually suspended by the use of this agent, although the neoplasm is un- affected in its growth and development. It is a curious circumstance that attacks, nocturnal exclusively, are less amenable to the bromide- treatment than those which occur in the daytime. Cases of the petit mal, or epileptoid seizures, in which there is tempo- rary loss of consciousness without convulsion, or with a transient spasm of the facial muscles, etc., are as a rule not so much benefited as are cases of the grand mal. Hysterical convulsions (hystero-epilepsy) are benefited by the bromide in the degree in which they partake of the nature of true epilepsy. Simple hysterical convulsions are rarely im- proved even by a course of this medicine. It has been repeatedly shown, as was first observed by Sir Charles Locock, that the bromides are especially eflicacious in cases of epilepsy of sexual origin. Although the bromide of potassium is less effective in the epilepsy of childhood than of adults, it is an excellent remedy in infantile con- vulsions dependent on reflex irritation. After the removal of the irri- tation the convulsive attacks may continue, but they can be arrested by the use of the bromides. The cerebral congestion which precedes the convulsive seizure may be relieved by this agent, and the threat- ened attack averted. The author is convinced that the convulsions which attend tubercular meningitis may be prevented by the bromide, but this agent exerts no curative influence in this fatal malady. In the present state of our knowledge it is not possible to indicate with any degree of certainty, besides the points mentioned above, the kind of cases in which a successful result may be expected from the bromide treatment. If no improvement be manifest after several weeks of treatment, and if bromism be induced, the case must be re- garded as an unfavorable one for this treatment. Brown-Sequard thinks that the cropping out of an " acne-like eruption on the face, neck, shoulders," etc., is an evidence that the bromide is proving cura- tive, and he even asserts that there is "a positive relation between the intensity of the eruption and the efficacy of the remedy against epilepsy." According to Yoisin, the abolition of reflex nausea — ascer- tained by passing a spoon as far back as the epiglottis, without causing attempts at vomiting — is an indication of the successful action of the remedy. Furthermore, he regards the following physiological effects 35 546 CEREBRAL SEDATIVES. as evidence of curative power : " Hypnotic manifestations, general las- situde, an easy and rapid disappearance of reflex nausea, and antaphro- disiac action." Certain cases of epilepsy, in which the bromide of potassium fails to afford relief, are greatly benefited by strychnine. From this circum- stance it has been concluded that the former agent is most serviceable in cases in which a condition of hyperemia of the brain exists, and that the latter agent produces the best effects when a condition of cerebral anaemia is present. Various important considerations are connected with the adminis- tration of the bromides in epilepsy. The daily dose required varies from half a drachm to four drachms, the limit of the quantity admin- istered being determined by the effect produced. The occurrence of bromism and the arrest of the seizures are the evidences that a suffi- cient quantity has been introduced into the organism. According to the author's experience, forty grains of the bromide, dissolved in water and given before each meal, or three times a day, and if required a double dose at bedtime, is an amount of the medicine which it is rarely necessary to exceed. When the convulsive attacks have ceased, a sin- gle dose of sixty grains at bedtime will generally suffice ; but this re- sult must not be interpreted too favorably, and the remedy discon- tinued, for an immense experience has now demonstrated that security against a return of the attacks can only be attained by a continuance of the remedy for two or more years after all indications of epilepsy have disappeared. After the continuous use nightly of the remedy for a year, the dose may be so far diminished as to give it on alternate nights. Should the attacks recur after temporary cessation, larger doses are required as a rule. The long-continued use of the bromide of potassium may produce very serious symptoms of bromism. The remedy must then be greatly reduced in amount or be discontinued, and tonics and restoratives ad- ministered until the organism recovers its tone. When there is much susceptibility to the action of the bromides, it is generally better to prescribe the bromide of sodium. This salt is equally effective in epi- lepsy, while it is much less depressing in its effects. It is not unfre- quently desirable to administer iron during a course of bromides. The author has had excellent results from the following : ^ Potassii bro- midi, | j ; ferri bromidi, gr. vj ; aquae, § vj. M. Sig. : A tablespoon- ful three times a day. Echeverria has made the observation that tak- ing strong coffee with the meals hinders the development of bromism. The troublesome and very disfiguring acne may be, in part at least, prevented by the conjoined administration of arsenic (three to five drops of liq. potassii arsenitis). Brown-Sequard, with that fondness for complex combinations which he has always exhibited, recommends the following formula for epilepsy : ^ Potassii bromidi, § j ; ammo- BROMIDES. 547 nii bromidi, 3 ijss ; potassii iodidi, 3j; potassii bicarb., 3ij ; infus. calumbae, 3 vj. M. Sig. : A teaspoon fid before each meal, and three teaspoonfuls at bedtime. There is probably no advantage in this com- bination, and it is execrable as regards taste. It is true sometimes better results are obtained from a combination of bromides than from the bromide of potassium alone. It is always advisable to combine the iodide of potassium with the bromides, when there is reason to suspect syphilitic cerebral lesions, or when degenerate changes may appear to be taking place. Vaso-motor disturbances, elsewhere than intra- cranial, are relieved by the bromides. " Such symptoms are, for example, sudden numb- ness, coldness, deadness, or pricking sensations in one or more limbs ; sudden distressing but indefinable feelings in the epigastrium, abdo- men, or hypogastrium ; or sensations akin to rigor, with much anxiety and palpitation, or ' fluttering,' of the heart. In such cases it may be observed that the local circulation is interfered with ; that, for exam- ple, the pulse in one arm becomes faltering, irregular in force and rhythm, occasionally intermitting, while that in the other arm may remain unaltered, and the beat of the heart may maintain its normal character." The painf id flushings of the face, and the sense offidlness in the head, which occur so frequently at the climacteric period in women, may often be removed by the bromides. Certain of the respiratory neuroses are greatly relieved by the bromides. Laryngismus stridulus, when present, may be suspended by the prompt use of full doses, and the tendency to frequent recur- rence of the attacks obviated by the steady and continued use of mod- erate doses of this remedy. It may be combined with chloral : $ Potassii bromidi, 3 ij ; chloral, hydratis, 3 ss ; syrup, tolu,, § ss ; aquae, I jss. M. Sig. : A teaspoonful every half -hour. The bromides greatly relieve the spasmodic element of whooping-cough, but they do not ap- pear to shorten the duration of the disease. A combination such as given above, for a child of two years, may be prescribed in whooping- cough during the spasmodic stage, and in proportionally larger quan- tity for older children. In spasmodic asthm a very great relief is sometimes afforded by the use of bromides, but these remedies lose their effect very quickly. The best results are obtained from a combination of the bromide with the iodide of potassium : 3 Potassii bromidi, | j ; potassii iodidi, f ss ; aquae, § iv. M. Sig. : A teaspoonful in sufficient water every half- hour or hour. Cough which is merely reflex (stomachal, intestinal, renal, uterine, ovarian) can usually be cured by the bromides. It is said that a gar- gle of the bromide of potassium will diminish the cough of phthisis. The author has ascertained that it is only occasionally that such a for- 548 CEREBRAL SEDATIVES. tunate result can be achieved in this way. Such a diminution of the sensibility of the fauces can be produced by a few large doses of the bromide of potassium, that this expedient has been proposed to facili- tate laryngoscopy and rhinoscopy. In certain neuroses of the genito-urinary organs, male and female, excellent results have been obtained by the use of the bromide of potas- sium. Abnormal sexual excitement and nocturnal seminal emissions may be checked by this remedy. The condition of plethora is the in- dication for the bromide. "When the sexual organs are much relaxed, the erections feeble, and the seminal fluid watery, especially if there be such a constant stillicidium of semen as to constitute the so-called diurnal losses, the bromide of potassium does harm. The more nearly nocturnal seminal losses approach the physiological type, the more effective the bromides. As they act by diminishing the blood-supply to the erectile organs, it is obvious that they are contraindicated when there is debility, and when the erections are feeble. They prove com- pletely successful when the erections are normal as to character, but teasing and persistent. The various nervous disturbances growing out of unsatisfied sexual desire are quieted by these agents. As a rule, nymphomania and satyriasis dependent on cerebral lesions are not diminished or prevented by the bromides. Bromide of potassium, in full doses, has been proposed for the relief of chordee. The result is generally disappointing, but occa- sionally relief is experienced from it. Very large doses ( 3 j every four hours) are necessary. Menorrhagia, dependent on ovarian irritation, is usually promptly arrested by these agents. Sometimes metrorrhagia, even when due to a fibroid, is remarkably improved by their use, but success is not in- variable. Various functional nervous disorders associated with, or dependent on, derangements of the sexual system — for example, such as are grouped together under the term spinal irritation — are treated with occasional success by the bromides. It is to be noted, however, that a condition of general anaemia or local spinal anaemia, which usually coexists, is a contraindication to the use of these agents. They are useful in proportion to the degree of plethora present. Local Uses of Bromides. — Epithelioma of the face has been cured by applying to the ulcerated surface bromide of potassium in fine powder.

In the treat- ment of epilepsy, the acid is far inferior to the bromides. In spas- modic cough it has proved very useful. In angina pectoris, or cardiac irregularities due to acidity of the stomach, it is highly useful, given before meals. The tinnitus, dizziness, and headache caused by quinine may be largely diminished, if not wholly prevented, by the addition of hydrobromic acid to the solutions containing the former, or by giving the latter some time after. The after-nausea and depression caused by morphine may be obviated by the simultaneous or subsequent ad- ministration of hydrobromic acid. Authorities referred to : Anstie, Dr. F. E.

It is pretty well established that the extracts are nearly, if not quite, inert. The best preparations are the fluid extract and alkaloid. Composition. — The special powers of hemlock are due to a pecul- iar alkaloid (conine). This is an oily, limpid liquid, having a strong alkaline reaction, a peculiar odor resembling the urine of mice, and a specific gravity of 0*88. It probably exists in the plant in the form of the malate ; but, by some authorities, the acid with which it is com- bined is supposed to be an acid peculiar to conium, the coneic acid. Conine is associated with ammonia, and another crystallizable alkaloid, conhydrine. Conine is quickly decomposed by beat. Exposed to the air, it is soon converted into a brownish resin, and becomes inert. Hence it is that the preparations of conium possess but little activity, and are so frequently, indeed entirely, wanting in physiological and therapeutical effects. It is better, therefore, to administer the alkaloid, which, be- ing soluble in alcohol, may be administered in that menstruum, or it may be converted into an acetate and dissolved in a mixture of alco- hol and water. It is to be noted, also, that different specimens of conine differ remarkably in activity ; hence, whenever a new prepara- tion is begun, the minimum dose should be first administered until its real power is ascertained (Burman). Conine. — Dose, gr. -fa — gr. fa — gr. fa , or in minim-doses from tq, fa — tii ij« Half a minim of conine (pure) is about equivalent in activ- ity to f j of the best succus conii. The chlorhydrate and especially bromhydrate of conine are greatly to be preferred, not only to the pure alkaloid, but to any of the preparations of conium. The bromhydrate crystallizes in the form of colorless, prismatic needles, which are freely soluble in water and also in alcohol, have but little taste, and no odor (Mourrut). The dose of this salt ranges from fa of a grain to J, -J, even 1 grain. It is not actively toxic. By reason of this fact, its freedom from a disagreeable taste or odor, and its solubility, the brom- CONIUM. 551 hydrate is a most desirable preparation for administration, either by the stomach or hypodermatically. Antagonists and Incompatibles. — The caustic alkalies and tannic acid are chemically incompatible. Physiologically considered, the ac- tions of conium are antagonized by nux-vomica and its alkaloids strych- nine and brucine, by picrotoxin, and the tetanizing agents in general. Synergists. — Gelsemium, tobacco, veratrum viride, aconite, me- thyl-strychnium, hydrocyanic acid, and curara, increase the action of conium. Physiological Actions. — The preparations of conium possess a considerable degree of acridity, and are therefore apt to produce gas- tric irritation, nausea, and vomiting. These results sometimes follow the subcutaneous injection of conine. The active principles readily diffuse into the blood. What changes, if any, they induce in the blood are quite unknown. It is probable that they limit the power of the red blood-globules to convey oxygen to the tissues on which they have a selective action — the motor nerves. When an active dose of conine is administered, weakness of the legs and a sense of weight and fatigue of these members are first experienced. The eyelids become heavy and droop somewhat, and double vision, or confused vision, a feeling of torpor of the mind, and giddiness, follow. Speech is also affected as respects vocal utterance, but the memory for words and the faculties of mind generally are un- impaired. When the dose is a lethal one, paralysis of the voluntary muscles — first of the inferior extremities — ensues ; there is consider- able vertigo, the mind is torpid and indifferent but not perverted, speech and vision are lost, the respiration becomes labored and slow from paralysis of the respiratory muscles, and death occurs from as- phyxia, the action of the heart continuing until after respiration has ceased. The mind remains unclouded to the last, except when delirium ensues from carbonic-acid poisoning. Convulsive movements generally occur in animals from retention of carbonic acid in the blood, and in man sometimes local convulsive movements. Sensation is unaffected until near the close, but a subjective sense of numbness is experienced in the feet and legs, without actual impairment of the functions of the sensory nerves. The body temperature is decidedly lowered, and in a direct ratio to the amount of the paralysis. The physiological effects of conine, even when produced by decid- edly large medicinal doses, are hindered if not entirely prevented by active exercise. When the muscular weakness, the heaviness and sense of fatigue in the legs are first experienced, if resisted and muscu- lar movements are carried on, these sensations disappear, and the whole duration of the physiological effects is much shortened. The action of conine is, primarily and chiefly, on the end-organs of the motor nerves ; the nerve-trunks next lose their excitability, and 552 MOTOR DEPRESSANTS. by an extension of the paralysis the spinal cord is at last involved. The muscular irritability remains unaffected. According to M. Veri- go, the paralysis proceeds from the spinal cord, outwardly, to the ter- minal filaments of the motor nerves. But it is probable that this experimenter operated with a preparation of conine containing methyl- conium, which has been shown, by Crum Brown and Fraser, to affect first the motor columns of the spinal cord. No constant and characteristic post-mortem appearances seem to be produced by conine. The left cavities of the heart are found empty, and the right distended, but these are products of the mode of dying, and are not directly due to the action of the poison. The blood is generally fluid, and the coagula are soft. Elimination takes place by various channels, chiefly by the kidneys. Conine has been found in considerable quantity in the liver, lungs, and spleen. Therapy. — Formerly the preparations of conium were much used for a supposed discutient or resolvent action in glandular enlargements, and in certain hinds of tumors. But, since it has been shown that the preparation chiefly employed for this purpose (the extract) is practi- cally inert, the supposed cures effected in this way are justly regarded as examples of the post hoc. Influenced by the same considerations, conium was supposed to have an alterant and anodyne action in cancer. But, since, in the progress of physiological research, it has been shown that conium affects the motor and not the sensory nerves, it is no longer employed to relieve the pains, or to arrest the growth and diffusion, of cancer. It is right to add, however, that able practitioners hold that the discutient and resolvent powers of conium are well established in clinical experience (Stille). The true uses of conium are those deduced from a consideration of its physiological actions. As it lowers the functional activity of the motor nervous system, it is indicated in those cases of disease in which motor activity is in excess. Very valuable results have been obtained by the use of conine in mania, administered with the view of subduing excessive motor excitement. Its real utility consists in quieting mus- cular agitation, and thus preventing emaciation and maniacal exhaus- tion. It is considered to be most suitable to the treatment of acute mania, without organic brain-lesion (Burman). The dose required for this purpose is th, ss — tti iij, or subcutaneously, commencing with one tenth of a minim, and gradually increasing it until some characteristic physiological effects are produced. The succus conii has been used by Harley and others with success in chorea. The special object for which it is used in this malady is to quiet the excessive muscular agitation ; but, in order to accomplish this result, a sufficient quantity must be administered to produce distinct physiological effects. To quiet muscular agitation is not alone suffi- CONIUM. 553 cient to cure chorea ; a suitable hygiene, proper alimentation, and re- storative agents, are indispensable. Some cases of paralysis agitans are remarkably benefited by conium, but it is of little avail in cases of sclerosis, or when important structural alterations have occurred. Co- nine is certainly indicated in tetanus, hydrophobia, and strychnine- poisoning, but hitherto it has not succeeded, probably because in- ert preparations were employed. The author has ascertained that in animals conine rather hastens than retards the lethal effects of strychnine. In whooping-cough, asthma, and laryngismus stridulus, good effects have been obtained by the use of conium, carried to the point of in- ducing its characteristic physiological effects. A priori, the best re- sults might be expected from the use of conium in epilepsy, but it is by no means comparable to the bromides. According to Echeverria, conium is serviceable in those cases of epilepsy " attended by cerebral derangement and vertigo." The state of blepharospasm, which accompanies strumous ophthal- mia, is relieved by considerable doses of conium. It is necessary in the treatment of this, as of other motor disorders, to give a sufficient quantity of conium to produce sensible physiological effects. The Hypodermatic Use of Conine. — The alkaloid itself is much too irritant for subcutaneous use. The local inflammation which it sets up prevents absorption, and hence the effects are nil. The alcoholic solu- tion is almost equally objectionable. The following formula, proposed by Bur man, is the best for the subcutaneous use of the alkaloid : 5 Coninse, 3 iij, V{ xij. Acidi acetic, fort., 3 iij, f\[ xij. Spts. vmi rect., 3 j. Aquae destillatae ad § ij. M. Sig. : Dose, one minim to begin with, and gradually increase as necessary. Five minims of this solution contain one minim of conine. " The acid must be added carefully and gradually until neutraliza- tion, or as near an approach to it as possible, is attained ; litmus-paper being used, from time to time, to determine the reaction." Different specimens of conine may require somewhat different proportions of acid to neutralize it. If the mixture be turbid after the addition of the spirit and water, a little more spirit may be added. The subcutaneous injection of conine may be practiced instead of the stomach administration, in all of the forms of disease for which this remedy is prescribed. By Burman this mode of administration has been practiced with much success in the treatment of acute mania ; by Pletzer, in asthma ; by Erlenmeyer, in .emphysema and angina pec- toris ; by Lorent, in pneumonia and pleuritis ; and by Eulenburg, in blepharospasm. A marked decrease in the pulse-rate, and in the tern- 554 MOTOR DEPRESSANTS. perature, has been observed to follow the hypodermatic injection of conine in these diseases. The rational indication for the use of conine in pneumonia and pleuritis is, to give the organs physiological rest by inducing a paretic state of the respiratory muscles. A solution of bromhydrate of conine is greatly preferable to any form of the alkaloid, for all purposes, but especially for subcutaneous injec- tion. The following will prove useful : $ Coninae bromhydratis, gr. viij ; aquae, vel aquae lauro-cerasae, J j. M. Sig. : Ten minims con- tain one sixth of a grain. As Tiryakian and also Tuloup have shown, the effect of this agent declines by repetition, and hence the dose must be increased every few days. Two doses every twenty-four hours will usually be sufficient to maintain a constant effect. By the authors above mentioned, by Dujardin-Beaumetz, Prevost, Rochefontaine, and others, it is asserted to be very effective in spasmodic affections, espe- cially of the respiratory organs — in whooping-cough, asthma, dyspnoea, laryngismus stridulus, spasm of the glottis, hiccough, etc. It has been used with success in tetanus by Chisolm and by Cory. Conine and Morphine. — The effects of conine are in every way heightened by morphine. These agents have been very successfully employed in acute mania, conjointly administered subcutaneously. " Conine acting on the purely motor centers, in a sedative manner, and morphine acting in a similar way on the sensori-motor and ideo- motor centers, it follows, as a fair corollary, that the combination of the two, in subcutaneous injection, should lead to effects directly an- tagonistic to the condition of maniacal excitement ; and, such being in fact the case, they may be thus used together with very great suc- cess in the treatment of mania." When nerve-pain and muscular spasm coexist, the best results may be expected from the combined administration of morphine and conine. Authorities referred to : Burman, Dr. J. Wilkie.

History. — There are no official preparations. The substances known under this name vary much in purity, and differ in origin. True curara is a poisonous substance, prepared by the Indian tribes of certain districts of South America, and known under the names woo- rara, urari, wurali, etc. A specimen examined by Mitchell and Ham- mond consisted of two distinct preparations named respectively carro- val and vao, the former more closely corresponding to the European specimens. Curara is obtained for the most part from several plants of the Strychnos family, as Strychnos toxifera, S. cogens, and from Paulinia cururu. An extract from these plants, it is supposed, is mixed with the venom of certain poisonous reptiles, and possibly with other animal substances. As the arrow-poison of different tribes differs not only in strength, but in the character of the effects produced* by them, it is certain that they are derived from different sources. That which is now obtained in commerce as curara, and which agrees in the main with the description of Bernard, is the substance referred to in this article. Composition. — Curara occurs in small, irregular masses, of a dark- brownish color, somewhat slimy, and looking like a dried vegetable extract. The mass is in part soluble in water, and the undissolved residue is composed, for the most part, of starch-granules, vegetable cells, oil-drops, and other vegetable structures (Mitchell and Ham- mond). The existence of an alkaloid in curara had been suspected by Boussingault, but it was not actually discovered until 1865, when it was isolated by Preyer. The estimates formed of its activity vary : by Preyer it was held to be twenty times stronger than the crude drug, but by Beigel only six times ; but these differences are readily ac- counted for in the varying qualities and activity of curara. Curarine, the alkaloid, is crystallizable, deliquescent, and forms with acids salts, which are also crystallizable. The dose will range from y^q gr. to fa gr. by the stomach — from -g-J-g- gr. to -^-^ gr. when administered subcutaneously. A larger quantity may be necessary when distinct physiological effects are to be produced. Mitchell and Hammond give the name carrovalia to the alkaloid which they obtained from carroval. The dose of woorara or curara, the crude drug, will range from fa gr. to -J- gr. It is desirable to try on some inferior animal the activity of any new specimen before using it on man. Antagonists and Incompatibles. — As curara is a paralyzer, it is antagonized by those agents which act in the opposite manner on the spinal cord. From the physiological standpoint, strychnine and atro- pine are appropriate antagonists, opposing the tendency to death by failure of respiration. Remarkable results have been obtained in ani- mals by artificial respiration. An animal will recover from twice the 556 MOTOR DEPRESSANTS. fatal quantity, if respiration be kept up until elimination occurs, which is speedy. As in the case of the other alkaloids, curarine is destroyed by the caustic alkalies. Synergists. — The paralyzers in general, especially the respiratory group, promote all of the actions of curara. Physiological Actions. — The taste of curara is bitter. Applied to the unbroken integument, it is not absorbed ; but swallowed, it slow- ly diffuses into the blood, and produces characteristic effects. Vul- pian finds that it is absorbed more rapidly when injected into muscular masses than when simply thrown under the skin. According to the observations of Yoisin and Liouville, made on man, the salivary, nasal, and lachrymal secretions are increased. It is probable that the gastro- intestinal secretions are also promoted. The rate of diffusion into the veins from the stomach varies, but it takes place in from twenty min- utes to a half -hour ; but even a longer time than this maybe required. The action of the heart increases ; the pulse rises a number of beats and may be dicrotic ; the temperature ascends two to three and a half degrees, and the respirations are accelerated, four to eight times per minute being added to the usual rate. Voisin and Liouville ventured on the exhibition of larger doses with the following result : the symp- toms began by a more or less violent chill ; the heart beat rapidly, reaching 140, and the pulse became weak ; the respiration was labored and sighing ; the temperature rose, and double vision, sometimes with mydriasis, sometimes with myosis, set in. The legs became weak, co- ordination was destroyed, and the vertical position could not be main- tained. The mind continued undisturbed. The paralysis disappeared after a short time, but a sense of fatigue persisted in the limbs for some hours. The increased temperature was accompanied by the usual symptoms of fever — there were, besides the accelerated pulse and respiration, headache, thirst, and perspiration. It was by means of curara that Bernard demonstrated the exist- ence of contractility as an independent endowment of muscular tissue. Curara, by poisoning the end-organs of the nerves in the muscles, sepa- rated these organs, and thus permitted a study of the agency of each. In all classes of animals, as in man, curara induces paralysis of move- ments : locomotion, the erect posture, breathing, finally the heart's ac- tion, are arrested. The paralysis induced by curara is not due to an abolition of the excitability proper to the motor nerve-trunks, but to a modification set up in the terminals of the intra-muscular nerves. This fact is proved by the well-known experiment of Bernard, repeated by Kolliker, Zeleuski, Yulpian, and numerous other experimentalists, in which a frog is paralyzed by curara in all parts of the body except one limb which has been ligatured to prevent the access of the poison to it. The muscles of the unpoisoned limb react normally to stimula- tion, to the will, and to reflex impressions from distant parts. The CURARA. 557 muscles of the poisoned parts of the body act on direct stimulation, but not by the will nor by any direct or reflex excitation conveyed by the nerve. The paralysis must therefore be due, as above stated, to the effect of the poison on the terminals of the nerve in the muscular tissue. As movements can be induced in the muscles of the unpoi- soned limb by irritation of the skin at a distant point, it is clear that the sensory nerves and the reflex function of the spinal cord continue active. It has been abundantly demonstrated that in curarized ani- mals the spinal cord preserves its functions for a long time. If, how- ever, a large quantity of the poison is administered, and a fatal result prevented by artificial respiration, the excitability of the cord is at first increased but afterward paralyzed (Yon Bezold, Yulpian, etc.). The motor and sensory nerve-trunks are also finally affected, but this is a secondary action, and ascertainable in curarized animals only by main- taining artificial respiration a sufficient length of time. It follows, then, that all parts of the nervous system are ultimately paralyzed. The action begins in the end-organs of the motor nerves, and then grad- ually extends to all parts, if the dose is large enough and life is main- tained by artificial respiration. Curara also acts on the accelerator nerves of the heart, at first stim- ulating and afterward paralyzing them. The action of the heart is increased, also, by the paralyzing effect of curara on the terminals of the pneumogastric, thus removing the inhibition. So decidedly is the vagus affected by full doses of curara, that galvanic irritation does not arrest the movements of the heart (Von Bezold). Notwithstanding the increased action of the heart, the blood-pressure is lowered by cu- rara, due doubtless to a paralyzing action on the organic muscular fiber and consequent dilatation of the vessels. The effect of curara on the sympathetic is variously interpreted. According to Yulpian, the iris contracts on changes in the amount of light falling on the retina in curarized animals ; the pupils dilate on faradization of the skin ; dila- tation of the vessels of the posterior members and an elevation of tem- perature take place in a curarized dog on faradizing the central portion of the corresponding sciatic ; very energetic reflex contractions of the stomach, intestines, and bladder are obtained in curarized animals by faradizing the skin of different regions of the body (Yulpian). These facts indicate that curara does not destroy but rather stimulates the functions of the sympathetic. Curara acts on the lymph-vessels of frogs. According to Tarchanoff, the liquid which accumulates during curarization grows richer in leucocytes ; also the blood contained in the vessels becomes more concentrated, the relative proportion of red globules being increased. As the accumulation of leucocytes takes place in the lymph-sacs, there is a corresponding diminution of them in the blood. These changes are due to the paralysis of the peripheric vessels (Tarchanoff). 558 MOTOR DEPRESSANTS. Curara, as has been stated, produces an obvious rise of temperature in the extremities. This is supposed to be due to paralysis of the pe- ripheral vessels. In the interior of the body, however, there ensues an equally constant decline of body-heat (Tscheschichin, Rohrig und Zuntz). This lowering of the central temperature is due to the loss of heat at the periphery by the cooling of the blood detained in the superficial vessels. Bernard long ago ascertained that curarized animals became dia- betic. It seems probable that this result is due to the paralysis of the vessels of the liver. On the other hand, Bock and Hoffmann have ap- parently demonstrated that the production of glycosuria is the result of increased activity of the liver. It may be due to the fact that the sugar formed does not undergo oxidation, for Jolyet has ascertained that in curarized animals the excretion of carbonic acid is much below the amount in health. By reason of the changes in the vascular sup- ply, curara affects the functional activity of various organs. The in- creased production of saliva, and of the nasal and intestinal secretions noted at the outset, is due, there is little doubt, to this fact. The elimination of curara takes place chiefly by the kidneys, but some escapes with the faeces (Koch). The urine of a curarized animal will poison another animal, and this may be repeated to several sub- jects. The retention of the urine charged with curara, in the bladder, will continue the effects of the poison by reabsorption. This state- ment has been the subject of considerable controversy. It has been denied that the mucous membrane of the bladder possesses the power to absorb again into the circulation poisons dissolved in the urine in the process of excretion. Brown-Sequard appears to have been the first to prove, by direct experiment, that alkaloids could be thus ab- sorbed, and some recent observations have confirmed the accuracy of his experiments. In respect to curara, as to other organic alkaloids, when poisoning occurs, it is an obviously proper expedient to keep the bladder empty, if necessary, by catheterization. Therapy. — The applications of curara to the treatment of disease follow from the results of the physiological study. Being a motor and not a sensory paralyzer, it is adapted to the treatment of muscular cramp and spasm. It is one of the remedies employed against strych- nine-poisoning, and although from the theoretical standpoint such treatment may seem proper, yet in actual practice it has not succeeded. That a remedy obtained from members of the strychnos family, and a paralyzer in action, should antagonize strychnine, is a remarkable fact. In the process of preparation employed by the Indians, it is in a high degree probable that methyl strychnium is formed, and this substance, as was originally shown by Crum-Brown and Eraser, is a paralyzer, and acts precisely like curara. Curara has been used with a limited measure of success in tetanus. In the successful cases — for example, GELSEMIUM. 559 that narrated by Mr. Spencer Wells — large doses were administered. According to the statistics of Demme, of twenty-two cases of tetanus treated by this agent, eight recovered. Other methods have certainly succeeded better. Two cases of hydrophobia have been reported in which a cure followed the use of curara. One of these, reported by Dr. Watson, was examined, and the diagnosis confirmed by Dr. Flint, of New York. The first dose was -^ gr., and subsequently \ gr. and \ gr. were given. The value of this statement is impaired by the fact that the different specimens vary so much in activity. M. Vella has successfully treated a case of tetanus by cutaneous absorption of the agent ; but the usual mode of administration has consisted in the sub- cutaneous injection. This subject, as M. Vulpian has well said, has lost its interest since the discovery of the utility of chloral. It is in a high degree probable, however, that curara would be greatly more successful if it were pushed in these cases to obtain its full physiologi- cal influence, and the complete suspension of the spasms. By Voisin and Liouville curara has been extensively employed as a remedy for epilepsy. The facts already mentioned in regard to the action of this agent in producing febrile phenomena were obtained from the experiences with epileptics. They find that attacks may be prevented, and the condition of epileptics much improved, by the timely administration of this remedy. It has proved useful in chorea, in tie-douloureux (Beigel, Du Cazal), but other remedies are doubtless better. Authorities referred to : Beigel, Dr. II.

The so-called gelseminine is obtained by evaporation of the tinc- ture, and is a very uncertain preparation ; the dose is gr. ss — gr. ij. It is only used by the eclectic practitioners. Disappointment is frequently experienced from the use of gelse- mium preparations, owing to the fact that they are made from the dried root. In the process of drying, even spontaneously, the alkaloid disappears. The most trustworthy preparations are the official, pre- pared conscientiously from the fresh root. Composition. — Gelsemium contains a very powerful alkaloid — gel- semine or gelsemina — and gelsemic or gelseminic acid, by some said to be identical with cesculin ; but Wormley has shown the fallacy in the evidence on which this statement was based, and Fredigke's account of gelsemic acid agrees with Wormley's in all essential particulars. It contains also an acrid resin, volatile oil, gallic acid, a yellow color- ing-matter, besides some other unimportant ingredients. Gelsemine. — In its pure state gelsemine (gelsemia) is a colorless, odorless solid, having an intensely persistent, bitter taste. It has strongly basic properties, completely neutralizing the most powerful acids, forming salts of which the sulphate, nitrate, chloride, and acetate are freely soluble in water (Wormley). Dose, gr. -fa — gr. ^V- Antagonists and Incompatibles. — The caustic alkalies and tan- nic acid are chemically incompatible. As respects the physiological actions, gelsemium is antagonized by the diffusible stimulants, by alcohol, ammonia, opium, digitalis, etc. The lethal effects are best treated by emetics, warmth, alcoholic stimulants, by faradization and artificial respiration, by morphine subcutaneously, and, according to Fredigke, by the tincture of xanthoxylum fraxineum. Synergists. — Conium, physostigma, tobacco, opium, etc., when ad- ministered with gelsemium, increase its effects in the whole sphere of its physiological activity. Physiological Actions. — The preparations of gelsemium have a bitter and somewhat aromatic taste, and a narcotic odor. They do not produce gastric irritation. The active substance, being crystalloidal, diffuses into the blood with facility. In moderate doses, but sufficient to produce decided physiological effects, gelsemium causes a feeling of languor and mental calm, slowing of the action of the heart, drooping of the eyelids, dilatation of the pupil, and some feebleness of muscu- lar movements. In larger doses the physiological effects are as fol- lows : vertigo, double vision, amblyopia, paralysis of the levator pal- pebrae so that the upper eyelid can not be raised, dilated pupil, labored respiration in consequence of a paretic state of the respiratory muscles, slow and feeble action of the heart, great muscular weakness, and sen- GELSEMIILM. 561 sibility to pain and touch much reduced. These effects are produced in about a half -hour after the stomach administration, and last two or three hours, when they subside. When lethal doses are taken, the above-described symptoms occur in a more intense degree. The gait is at first staggering, but the power of muscular movement soon ceases, and a sense of numbness diffuses over the body. The eyelids close (paralysis of the levator), the pupils dilate widely, vision is lost, and the pupils cease to respond to the stimulus of light. The lower jaw drops, and the power of speech is lost in consequence of paralysis of the muscles of the tongue. The respirations are labored, shallow, and irregular ; the action of the heart weak, feeble, and intermittent. Gen- erally the skin is covered with a profuse perspiration, but no other evacuation takes place. Death occurs from asphyxia, and the action of the heart ceases after the respiratory movements. Consciousness is preserved until near the close, and until carbonic poisoning ensues. In one instance (Wormley) extreme restlessness was noted, but generally there is a condition of calm, a soporose state, or the unconsciousness of carbonic-acid narcosis, and convulsions never occur. The author's investigations have demonstrated that gelsemium is a paralyzer of motility and sensibility ; that sensibility is first affected in cold-blooded animals (frogs), and afterward motility, and that in warm- blooded animals the motility is affected before sensibility. As respects the seat of the action, the author has ascertained that the end-organs of the motor nerves, and the nerve-trunks, do not lose their irritability, and that the muscular contractility is unimpaired. " Its paralyzing effect is due to its action on the motor center, and not to an action on the peripheral nerve-fibers. It acts also on the sensory portion of the cord, producing at last complete anaesthesia ; but this effect in warm- blooded animals, and in man, is toxic only, and follows the paralysis of the motor functions." Applying the precise observations which are made on animals to the explanation of the lethal effects which have occurred in man, we are conducted to the following conclusions : the disorders of voluntary movement, and the more or less complete pa- ralysis of the motor and of the sensory functions, are due to the effects of gelsemium on the motor and sensory portions of the cord, the func- tions of the sensory columns resisting longer the action of the poison. The labored respiration is due to the paretic state of the respiratory muscles, especially of the diaphragm. The depressed action of the heart is probably secondary to the diminished respiration movements, which produce this result by impeding the flow of blood through the pulmonary capillaries. The dilated pupil, the double vision, the ptosis, are due to paralysis of the third pair. In rabbits and cats gelsemium, in lethal doses, affects motility in a very remarkable manner : when the paralyzing effects are becoming manifest — first in the fore extremities — these animals perform a series 36 562 MOTOR DEPRESSANTS. of backward movements, in which sometimes a complete backward somersault occurs. In pigeons, general muscular tremors precede the backward movements. No corresponding acts have taken place in the fatal cases observed in man. A very considerable reduction of tem- perature occurs from lethal doses in warm-blooded animals. The author's experimental observations on the physiological actions of gelsemium have since been fully confirmed by Ott, by Ringer, and by O. Berger, in an elaborate series of investigations. The study of Ringer and Murrell is a model of a research of this kind. Therapy. — Gelsemium is indicated in those maladies in which an exaltation of function has taken place in the motor and sensory spheres of the nervous system. Several cases of tetanus have been reported cured by this remedy ; but it is impossible to say whether these were examples of post hoc or propter hoc. A priori it might be expected that gelsemium would prove serviceable in this disease, because its ac- tion on the spinal cord is opposed to that which takes place in tetanus. In strychnine-poisoning in animals, however, the tetanic spasms are not prevented by the administration of gelsemium. In mania, with great motor excitement and wakefulness, this remedy is more useful than conium. To bring about the best results from its administration, doses of sufficient strength must be given to produce definite physiological effects, viz., dilated pupil, drooping of the eyelids, and a feeling of languor. In the condition of " horrors " from alcoholic excess, in sim- ple wakefulness, in the insomnia which results from over-excitement and too great physical activity, cures are not unfrequently obtained by the use of gelsemium. In the inflammatory affections of the me- ninges, and in cerebrospinal meningitis, sporadic or epidemic, with a decided febrile reaction, this agent is extremely useful in small doses (ttI v of fluid extract), repeated every two hours so as to maintain a uniform physiological effect. Gelsemium has been used with success recently in the treatment of neuralgia of the fifth nerve, but the good effects of the remedy in the painful affections of the fifth nerve are not always manifest (Berger). Cases cured by this remedy were, doubtless, not instances of tic- douloureux, but nerve-pain caused by cold, rheumatism, or temporary excentric irritation. Intercostal neuralgia, sciatica, and especially my- algia, are frequently cured by this agent (Jurasz) ; but considerable doses are necessary — from five to twenty minims of the fluid extract every three hours until the characteristic drooping of the eyelids, dila- tation of the pupil, and muscular languor, manifest themselves. In convulsive or spasmodic cough, gelsemium often affords remark- able relief. It is beneficial in the spasmodic stage of whooping-cough, reflex cough from irritation of the laryngeal nerves, the irritative cough of phthisis with scanty expectoration, and the nervous cough of hysterical subjects. In some cases of spasmodic asthma great relief GELSEMIUM. 5G3 is afforded by gelsemium, but, as is the case with all other remedies for asthma, it frequently fails and loses its good influence even in those cases in which it was at first successful. The author has witnessed excellent results from the use of gelse- mium in acute inflammations of the lungs and pleura. In pneum,onia it affords rest by diminishing the activity of the respiratory function ; it allays cough, and, by depressing the cardiac movements, it lessens stasis of the pulmonary capillaries and lowers the temperature. It is better to give medium doses {y\ iij — tt[ v of the fluid extract), every two hours, to maintain a constant effect within the limits of safety. It favors, when exhibited in this way, the occurrence of an early crisis, and assists in the production of one critical evacuation — the sweat. A similar mode of administration should be pursued in pleuritis, in which its use is equally rational and effective. Very great relief is afforded by the use of gelsemium in certain pelvic disorders in women. There is no more generally-useful medi- cine in ovarian neuralgia. The pains of dysmenorrhoea are also greatly alleviated by it. The evidence is conclusive that this remedy also suspends after-pains, and it is held by some good observers that it quiets the " nagging " pains of the first stage of labor. In these dis- orders of the female sexual organs, it is generally necessary to admin- ister a quantity of the remedy sufficient to produce some of its charac- teristic physiological effects. According to Bulkley, it is an . effective remedy for the relief of pruritus, and has given excellent results in the treatment of eczema. He prescribes from three to ten drops of the tincture, giving it every two or three hours until some of its charac- teristic effects appear. The first empirical use of gelsemium was in the treatment of the remittent or so-called bilious fevers of the South. A considerable num- ber of facts have been accumulated, which show that this remedy exercises a really beneficial influence in remittent and typo-malarial fevers. It is not an action of specificity — like quinine in intermittent and remittent fevers — and it is doubtful whether this supposed bene- ficial effect has any proper basis.

Composition. — The chemistry of arnica has not as yet been thor- oughly elucidated. Walz has isolated a principle (arnicine). The root contains an essential oil on which depends, in great part, its physi- ological activity. The oil is a complex substance. One of its most important constituents is trimethylamine, or an analogous principle. Antagonists and Incompatibles. — The actions of arnica are an- tagonized by ammonia, alcoholic stimulants, opium, camphor, etc. Synergists. — Aconite, veratrum viride, digitalis, and arterial seda- tives generally, increase the effects of arnica. Physiological Actions. — Arnica excites considerable irritation of the skin, if the contact be sufficiently prolonged. It produces when swallowed a sense of heat and acridity in the fauces, and increases the flow of saliva. It is decidedly irritant to the stomach, and causes in large doses nausea and vomiting, and choleraic diarrhoea. Its active principles diffuse into the blood. In small medicinal doses arnica in- creases the action of the heart and arteries, and excites the functions of the skin and kidneys. In large doses, probably after a short stage of excitement, depression of the circulation, of the respiration, and of the animal temperature, ensues ; violent headache is experienced, the pupils are dilated, and paresis of the muscular system comes on. In toxic doses arnica paralyzes the nervous system of animal and organic life, and death ensues in a condition of collapse. Therapy. — In febrile diseases and inflammations, when there is sthenic reaction, arnica in full doses depresses the action of the heart and lowers the arterial tension. It is, therefore, antipyretic. For the production of this effect, an infusion is probably a better preparation than the tincture. When, however, in febrile diseases there is present the condition of asthenia, small doses of the tincture (five minims) are to be preferred. That this remedy will produce different results, in TRIMETHYLAMINE. 565 small or large doses, need not occasion surprise. It is conceded on all sides that the effects of opium differ according to the size of the dose, and the frequency with which it is repeated. Good results have been obtained from the use of arnica infusion in mania and melancholia. The tincture of arnica is exceptionally ser- viceable in delirium tremens, with depression. In rheumatism and rheumatic gout, very decided curative effects are sometimes procured from arnica. The fact that it contains trime- thylamine is probably the true explanation of its utility in these affec- tions. It has also proved very efficacious in acute eczema, in erysipe- las, and other cutaneous affections of gouty and rheumatic origin. Dysmenorrhcea of the congestive form, acute metritis, and other acute pelvic inflammations, are also favorably influenced by the administra- tion of arnica. The tincture of arnica has a popular reputation for the relief of sprains, bruises, and external inflammations. The author has known violent erysipelatous inflammation to follow its application to a sprained ankle. It is extremely doubtful whether the good effects are more de- cided than those of a spirit-lotion. The infusion or decoction does not, it is said, cause local irritation. Planat has demonstrated that arnica is a remarkably effective application to boils. He directs one part of the extract and two parts of honey to be thoroughly incorporated, and the paste spread on some adhesive plaster, leaving a margin to secure its adhesion to the skin. The plaster is renewed every twenty-four hours. To increase the effect, Planat gives by the stomach the tinc- ture of arnica. Authorities referred to : Husemann, Dr. Theodor.

As the propylamine of commerce is a mixture of various substances, and is of uncertain composition, trimethylamine only should be used (Spencer). The dose of trimethylamine is four to eight minims. Its disagreeable taste may be disguised somewhat by peppermint- water. Properties. — Trimethylamine is a colorless liquid, having the composition C 3 H 9 N\ It dissolves freely in ether, alcohol, and water, has a strong alkaline reaction, and is inflammable. Chloride of Trimethylamine is a stable salt which crystallizes in long needles ; it is very deliquescent, and its solution when concen- 566 MOTOR DEPRESSANTS. trated has a caustic action on the skin and mucous membrane. It is free from odor, except when heated or mixed with an alkali, when the fishy smell is evolved. The taste of a solution of this salt is alkaline, but not disagreeable (Dujardin-Beaumetz). Dose, grs. ij to grs. v every three hours. Antagonists and Incompatibles. — Chemically trimethylamine is incompatible with the mineral acids, the salts of the metals, the alkalies (chlorides), and vegetable infusions. It should always be prescribed alone, in solution in some aromatic water. Therapeutically, it is an- tagonized by the stimulants, opium, belladonna, digitalis, etc. Synergists. — All agents depressing the vascular system and the temperature are synergistic. Physiological Actions. — Applied to the skin, mucous membrane, or areolar tissue, trimethylamine produces decided caustic effects, com- parable to those which result from the action of ammonia. It excites gastric pain when taken into the stomach in considerable doses, and will, doubtless, cause a high degree of inflammation if incautiously ad- ministered. The most characteristic effects are the lowering of the ac- tion of the heart, the depression of the temperature, and the diminution in the amount of urea excreted. In the physiological state Dujardin- Beaumetz found, in some experiments on himself, that the chloride of trimethylamine lessened the temperature and the pulse, but these re- sults were much more decided when it was administered in cases of acute rheumatism. The influence which this agent has on the excre- tion of urea is still more remarkable. The observations of Dujardin- Beaumetz show that a gradual but considerable decline in the excre- tion of urea is a constant result of its administration. On the other hand, Spencer says that the excretion of urea is sometimes increased, and, in one case in which the urinary discharge was carefully studied, the urine was almost trebled, and the urea more than doubled by the use of this remedy. If the diminution of the amount of urea were a constant result, as claimed by Dujardin-Beaumetz, the influence which trimethylamine has on the body temperature might be due to an in- terference with the combustion process. But the facts do not as yet justify the construction of a theory as to its mode of action. Therapy. — Thus far almost the only application made of trime- thylamine is in the treatment of acute rheumatism and gout. In some cases it appears to produce almost complete relief after the administra- tion of a few doses, but generally a longer time is required (Awenarius, Dujardin-Beaumetz, Spencer, Leo). It moderates, at once, the fever and the joint-pain, and very decidedly shortens the duration of the dis- ease. It is said to diminish the tendency to cardiac complication. This agent, having so decided an influence on the pulse, tempera- ture, and excretion of urea, will in the future doubtless be applied to the treatment of other maladies.

Dose, 3 ss — 3 ij. Tinctura Pilocarpi. — Tincture of pilocarpus ( 3 iv — Oj). Dose, 3 ss — 3 ij. (Not official.) Composition. — The important constituent is the alkaloid — pilocar- pine — which possesses the physiological properties of the drug. It combines with acids to form salts. The salts of pilocarpine crystallize in the oblique system. In 1880 another alkaloid was discovered, and to this the name jaborine was given (Harnack und Meyer). Subse- quent researches fully confirmed this (P. Castaing). These alkaloids are closely related in composition : probably identical, but having a different molecular arrangement. By heat, merely by concentration of an acid solution, pilocarpine is converted into jaborine (Hans Mey- er) ; and by washing with absolute alcohol they are separated, when united, as is very often the case in the commercial article. As these two alkaloids differ very greatly in properties, it is not surprising that the observations made with pilocarpine at first were very discrepant. Chemically they differ in that the salts of jaborine do not crystallize, and they dissolve more easily in ether and less easily in water. Physi- ologically, they differ even more decidedly. Jaborine acts like atro- pine, to which pilocarpine is a physiological antagonist. Pilocarpine Hydrochloras. — Hydrochlorate of pilocarpine. Mi- nute, white crystals, deliquescent, odorless, having a faintly bitter taste and a neutral reaction. Very soluble in water and in alcohol, but al- most insoluble in ether or chloroform. Dose, gr. y 1 ^ — gr. ss. Antagonists and Incompatibles. — The caustic alkalies, the per- salts of iron, and the salts of the metals generally, are chemically incompatible. A remarkable antagonism has been shown to exist between pilocarpine and belladonna (Ringer and Gould). Synergists. — Aconite, veratrum viride, gelsemium, and remedies 568 MOTOR DEPRESSANTS. which paralyze the vaso-motor nervous system, promote the activity of jaborandi. Physiological Actions. — The taste of jaborandi is rather hot and pungent. The considerable doses of the crude drug required to pro- duce physiological effects excite nausea and vomiting, especially if taken on an empty stomach. It has been shown, however, in recent experiments, that these results follow the use of the alkaloid ; hence it may be concluded that not bulk alone is the cause of the gas- tric distress, but that it is one of the physiological properties of the drug. The active principles of jaborandi diffuse readily into the blood. In about ten minutes after the infusion is swallowed, the face, ears, and neck become deeply flushed. Simultaneously perspiration begins on the skin, an abundant flow of saliva takes place, the nasal and bron- chial mucus, and the tears, are increased, and watery diarrhoea may occur. It is said that, when the salivary secretion is greatly increased, that of the skin is relatively less so, and vice versa (Fereol), but this is not generally admitted. The quantity of perspiration poured out by the skin is enormous — the sweat runs from the body and soaks the clothes. The quantity of saliva discharged is also very great. Ringer reports that in two of his cases the amount of saliva was respectively twenty-two ounces and twenty-seven ounces. According to Petithau, the sialogogue effect is constant, the diaphoretic action is somewhat less certain, and the diuretic effect uncertain. These conclusions are in accord with the general experience. The action of the heart is increased by jaborandi, but the arterial tension is notably diminished. The rise in the pulse-rate averages twenty beats, and the duration of this effect is about two and a half hours. A very distinct fall of temperature (0'5° to 2° Fahr.) ensues when the sweating begins, and this decline of body-heat is maintained on an average about four and a half hours. According to Robin, Gil- let de Grandmont, and others, a transient rise of temperature precedes the fall, but Ringer and Riegel deny the accuracy of this observation. In some subjects, very serious symptoms due to the sudden develop- ment of extensive pulmonary cedema have been observed by Thomas, Napier, Sanger, Jenkins, and others. The nauseant effects of pilocarpus and its alkaloid are, it is prob- able, referable to the action which it exerts on the muscular layer of the stomach and intestines. Very active movements of these organs follow its administration, and even a tetanizing action is observed. Secretion of the mucous membrane is increased, due, doubtless, to stimulation of the pancreas and the glands of the mucous membrane (Harnack und Meyer, Morat). The effects of jaborandi on children, according to Ringer, are, singularly enough, much less, for corresponding doses, than on adults, PILOCARPUS. 569 as respects the flushing, the sweating, the salivation, and the tem- perature. More or less drowsiness, both in children and adults, follows the profuse sweating, and pallor succeeds to the flushing. Chilliness is experienced with the cessation of the sweating stage. Languor and debility persist for some hours after the completion of the effects. The drowsiness is probably not due to a direct action of the remedy on the cerebrum, but to the greatly-diminished vascular tonus, and to the loss of fluid from the vessels. Vision is generally affected. The pupil is usually contracted, and the power of accommodation is im- paired. No characteristic or constant changes in the fundus of the eye have been observed on ophthalmoscopic examination. Locally ap- plied to the eye, jaborandi causes " contraction of the pupil, tension of the accommodative apparatus of the eye, with approximation to the nearest and farthest points of vision, and amblyopic impairment of vision from diminished sensibility of the retina." The eye resumes its normal state in about an hour and a half (Tweedy). The results of experiment indicate that the action of jaborandi is paralyzant of the vaso-motor nervous system. The flushing of the skin is doubtless due to dilatation of the arterioles, and the increased action of the heart must be referred to the same cause. The sphygmo- graph demonstrates the lowering of the vascular tension. The decline in temperature must be referred chiefly to the profuse transpiration, but the depression of the vascular tonus may also somewhat influence thi3 result. The data do not yet exist for a statement of the mode in which jaborandi excites the salivary and cutaneous secretions. It probably affects the end-organs of the excito-secretory nerves (Har- nack und Meyer, Yulpian, Dujardin-Beaumetz, Grocco, and others). That pilocarpus stimulates the gravid uterus is affirmed by many observers. Vander Neg asserts that, when injected subcutaneously or into a vein, it promptly induces uterine contractions, or increases the energy of those already existing. Kleinwachter reports two cases in which it induced premature labor. Three injections of two centi- grammes each produced this result in one case, and two injections suf- ficed in the other. Dr. Prochownick, of Hamburg, also reports two cases of eclampsia, in which the hypodermatic injection of hydrochlorate of pilocarpine inaugurated labor in a half -hour. It frequently fails, even in considerable doses, to have this effect. Of nine reported in- stances in which it was used to induce premature labor, in six it was successful and in three it had no effect. The cases in which uterine action has been induced were chiefly eclampsia, and hence there is an important source of fallacy. Elimination of the active constituents of jaborandi probably takes place through the organs whose functions are so powerfully excited. It is a remarkable circumstance that the amount of urea passing out 570 MOTOR DEPRESSANTS. in the sweat caused by jaborandi is enormously increased over the normal, amounting to from fifteen to seventeen grains. The urine is not increased, as a rule, but Gubler apparently demonstrated that small doses frequently repeated had a distinct diuretic action. His theory is based on the notion that, being a universal gland-stimulant, if the skin is not directly stimulated and the fluids directed to it, the kidneys will be acted on. In some instances the growth of hair has been pro- moted by the subcutaneous and topical application of pilocarpus (Pren- tiss, Andre, and others). The experiments which have demonstrated the existence of a physi- ological antagonism between jaborandi and belladonna have thrown much light on the action of the former. When the heart of a frog is arrested in the diastole by jaborandi, it immediately recommences its beat when atropine is subcutaneously injected (Langley). When the superior ganglion of the cervical sympathetic, and the lingual, and the pneumogastric nerve are divided, jaborandi administered causes pro- fuse salivary secretion ; but this action is at once antagonized and the secretion arrested by the injection of atropine. These agents, therefore, are exactly opposed as respects their action on the nerve- endings in the salivary glands (Carville). The effects of one grain of atropine, in a boy poisoned by it, were, as respects the state of the mouth and skin, antagonized by thirty grains of jaborandi. In three men the perspiration and salivation caused by sixty grains of jabo- randi were arrested by the subcutaneous injection of -j-J-g- of a grain of atropine (Ringer and Gonld). Comparative Action of Pilocarpine and Jaborine. — The differ- ences in physiological action between these alkaloids are infinitely greater than the chemical. There does not exist a finer illustration of the importance of molecular arrangement to physiological action. Given two alkaloids having the same ultimate constituents, their actions become antagonistic by reason of an unknown molecular arrangement. Jaborine, in its effects on the heart, lungs, pupils, and salivary glands, is identical with atropine. In the whole range of physiological antag- onisms, there is none more complete than that existing between atro- pine and pilocarpine. As in some specimens of pilocarpine — owing, doubtless, to faulty pharmaceutical processes — there is more or less jaborine, it is no longer difficult to explain how some observers have differed in their observations. As the effect of pilocarpine on the cir- culation and the sweat-glands is so completely antagonized by jaborine, it is in a high degree important, in prescribing the former, to secure a specimen free from the latter. Therapy. — Pilocarpus, acting as it does on the salivary glands, has been used with varying success in mumps, sometimes succeeding well, and then failing. According to Testa, if used in time it may arrest the development of the disease, and later may prevent metastasis. PILOCARPUS. 571 In salivation of pregnancy, it has succeeded perfectly in a few in- stances, but fails often ; atropine is generally much more certain and effective. It is contraindicated in all affections of the gastrointes- tinal mucous membrane, and in weak heart due to disease of its mus- cular substance, or of its contained ganglia, or of the valves. It is a remedy of great value in cardiac dropsy, provided the contraindica- tions above mentioned do not exist ; its therapeutic power being much the same as the vapor, hot-air bath, and other means for pro- moting free diaphoresis. The effusions of recent pleuritis, hydro- thorax, and ascites, have been quickly removed by this agent. In asthma with profuse expectoration (humid asthma), and in bronchitis with abundant, non-purulent exudation, it has often been very bene- ficial. It must be used with caution, or not at all, in the difficult breathing due to dilatation of the right cavities and great venous trunks. According to Berkhart, pilocarpine, injected subcutaneously, arrests the most violent paroxysms of spasmodic asthma, and the re- lief persists for some time. It is equally effective, in the author's ex- perience, in singidtus or hiccough, but there may be incurable lesions underlying the spasm, when, of course, the paroxysms may be expected to recur again. Probably the most conspicuous good results from the administra- tion of pilocarpine have been obtained in eclampsia, from the albumi- nuria of pregnancy, of scarlatina, or of acute Bright's disease. The powerful action on the sudoriparous glands, and the excretion of the urinary solids by the sweat, are the causes of the extraordinary relief obtained from this remedy in suitable cases. It should be borne in mind that pilocarpus tends to excite uterine action, and hence its ad- ministration may, under some circumstances, be improper ; but in most cases this effect is desired. There are, however, two important contra- indications : a weak heart, from thinning and atrophy of the walls of the organ, or from fatty degeneration, and a tendency to pulmonary congestion and oedema. In some instances, in a few minutes after the injection, the respiration became embarrassed by congestion and oedema of the lungs and by enormous bronchial secretion (Sanger, Napier, G. Thomas). It may be well to mention that atropine, subcutaneously, in one case in which it was administered, removed these symptoms and saved the patient's life. In renal dropsy, especially scarlatinal, there being no contraindication in the state of the heart, it is a remedy of the greatest utility. Pilocarpine has proved to be an important addition to the re- sources of the ophthalmologist. In inflammatory affections with effu- sion and exudation it brings about resolution and absorption (Wecker). According to Coursserant, there is no remedy comparable to it in the amblyopia of alcoholism and of tobacco -abuse. It has produced excellent results in detachment of the retina, chronic iritis, keratitis, 572 MOTOR DEPRESSANTS. haemorrhages into the vitreous, floating bodies, glaucoma, atrophic choroiditis, haemorrhages and exudations of the retina, commencing atrophy of the optic nerves, etc. (Gillet de Grandmont, Meyer, Gub- ler, Wecker, and others). The first-named author affirms that we find in pilocarpine " an absolute remedy against white atrophy." Be- ranger, following Gubler, proposes to use this remedy as a substitute for eserine in certain ocular affections requiring a myositic — an effect produced by pilocarpine when instilled in the eye. It has been used successfully de novo and as a substitute for eserine in certain paralyses of the ocular muscles — those consecutive to the fevers and other acute diseases. After the operation for cataract extraction, pilocarpine is used by Chalot to prevent exudations and other inflammatory changes. In the discussion which ensued before the Geneva Congress wheie this paper was read, various adverse opinions were expressed regarding the exhibition of this remedy in different ocular maladies. Especially was the danger emphasized — the danger in cases of cardiac and arterial diseases, and of pulmonary engorgement. Ringer has used jaborandi with success to increase the secretion of milk. As the milk-glands correspond in structure to the sudoriparous glands, and are merely differentiated and specialized for their particu- lar office, the effects of this drug in increasing the production of milk might have been, a priori, expected. The author has used recently a fluid extract of jaborandi successfully in a case of deficiency in the secretion of the milk of a nursing- worn an. But Dr. Max Strumpf denies that it has such power. In two cases of that very intractable disorder, diabetes insipidus, or polydipsia, Laycock has used jaborandi with the effect to reduce the quantity of urine in one case from three hundred ounces to one hundred and twenty ounces per diem, and, in the other, from one hun- dred and fifty-eight ounces to ninety-eight ounces per diem. M. Hu- chard reports the cure of a case of the same kind, and also one of glycosuria / on the other hand, Yulpian declares it to be useless. Mur- rell has found it to be useful in some cases of the sweats of phthisis and of other nocturnal sweats, but yet far inferior to atropine and picrotoxin. In scaly skin eruptions, pilocarpus has good effects by maintaining a moist state of the skin. It is the most efficient remedy for alopecia which we possess. In the treatment of this affection pilocarpine may be injected subcutaneously, or the fluid extract can be applied locally. The following is a very successful topical application : I> Ext. pilo- carpi fl., f j ; tinct. cantharidis, 3 ss ; lin. saponis, § ijss. M. Sig. : The scalp must be well rubbed with this lotion daily. In prurigo Pick had success, but failed in psoriasis, and he also succeeded in two cases of pruritus senilis and in one of urticaria. In alopecia pity- rodes, he had good results in ten cases, but not in alopecia areata. PHYSOSTIGMA. 573 Pick administered one sixth of a grain three times a day by the stomach. Recently Guttmann has brought forward pilocarpine as a remedy for diphtheria. He reports having successfully treated eighty-one cases without a single death, but these extraordinary results have not been confirmed. Numerous observations have been published, but out of the mass of cases and reports we can select only some of the most important. Soon after Guttmann's paper appeared, confirmatory state- ments were published by Lax, and directly contradictory by Lashke- witz. The latter lost all his cases treated with pilocarpine. Pitschen and Dilewsky, on the other hand, succeeded in curing many which would otherwise, they think, have died. Archambault treated twenty- one cases according to Guttmann's plan, and of these twelve died, a result which he considers bad. In this country Jacobi was one of the first to make a trial of the new remedy, and he pronounced against its utility. Payraudeau, who has made an exhaustive study of the sub- ject, offers some conclusions which seem to the author eminently sound. The false membrane in inaccessible situations is softened and detached by the action of pilocarpine ; it does not effect the elimination of the diphtheritic poison by the sweat which it induces ; it is apt to cause nausea, vomiting, and diarrhoea, and may in this way greatly increase the danger of the case ; it is positively contraindicated when the car- diac muscle is weakened in any way. Although these positions are perfectly tenable, there are facts more favorable to the utility of pilo- carpine. They are well stated by Courtois : The results of the treat- ment of diphtheria by pilocarpine, without being so good as were at first supposed, are nevertheless worthy of careful consideration. Chil- dren of less than five years offer such slight resistance to the action of the morbific germs of diphtheria, that they are rarely cured. Those above this age, in which the mixed form of the disease is most fre- quent, are especially favorable subjects for this treatment. The false membrane is more thoroughly detached, and has less tendency to be reproduced, than by any other treatment. All are now agreed that efficient support must be given the patient by food and alcohol during the pilocarpine treatment ; that cases characterized by extreme depres- sion of the vital powers, and by weakness of the heart, are unsuited for this remedy. Guttmann exhibited pilocarpine with hydrochloric acid and pepsin by the stomach, giving from -fa gr. to \ gr. Archambault adminis- tered the remedy by the stomach generally, but, in urgent cases, hypo- dermatically. Chiotti preferred rectal injections of a simple solution. Physostigma. — Calabar bean.

Composition. — Calabar bean contains two alkaloids, physostigmine and eserine. These have been supposed to be the same, but they differ in important particulars. Physostigmine has an alkaline reaction, is amorphous, colorless, and tasteless. Eserine crystallizes in colorless, rhomboidal plates, and has a bitter taste. Eserine has strong basic properties, and combines with acids to form salts, which are freely soluble. But they seem to agree perfectly in physiological action. The Calabar bean contains, besides these alkaloids, the ordinary con- stituents of the common bean, viz., albuminous matters, starch, and oil. PhysostigmincB Salicylas. — Salicylate of physostigmine. In col- orless, shining, acicular, or short columnar crystals, turning reddish on long exposure to light and air, odorless, having a bitter taste and a neutral reaction. Soluble in 130 parts of water, and in 12 parts of alcohol at 59° Fahr. Dose, gr. -j-J-g — gr. -fa. Antagonists and Incompatibles. — The vegetable astringents, tannic acid, and the caustic alkalies, are chemically incompatible. As respects physiological actions, physostigma is antagonized in a limited part, but not in the whole of its actions, by atropine, and still more by chloral. Therapeutically, the tetanizing agents may be regarded as opposed to physostigma. Synergists. — The paralyzers, or depressors of the motor nervous system, conium, gelsemium, nitrate of amyl, etc., act in harmony with physostigma, increasing its effects in the whole range of its physiologi- cal influence. Physiological Actions. — The preparations of physostigma are apt to excite nausea. Increased secretion of the gastro-intestinal mucous membrane, and increased peristalsis, follow their administration. The active principles quickly diffuse into the blood. Physostigma does not impair the respiratory function of the blood, but, after death, loose coagula are found, the globules have undergone changes of shape, and rectangular plates of hsemato-crystallin occur (Leven and Laborde). The action of the heart is affected by considerable toxic doses ; it is paralyzed in the diastole, and is flabby, but it contracts lazily on elec- tric stimulation. In less than lethal doses the action of the heart is slowed, and the arterial tension is, for a brief period, lowered, but soon rises considerably above the normal. As these -effects are not due to an action on the inhibitory apparatus, and follow when the heart is separated from the vaso-motor center by division of the spinal cord, it is probable that the action consists in a stimulation of the cardiac gan- glia, and a subsequent paralyzing action on the cardiac muscles. The same result may be due to a paralyzing action on the accelerator nerves PHYSOSTIGMA. 575 of the heart (Kohler). The respiration is more powerfully affected than the circulation. When a lethal dose is administered the respira- tion becomes slower and shallower, and death ensues from arrest of the respiratory movements (asphyxia), the heart continuing in action for some time afterward. Physostigma does not affect the centers of conscious impressions, and consciousness is preserved until the oxygenation of the blood is so far interfered with that carbonic-acid narcosis supervenes. Giddiness, vertigo, and a sense of muscular weakness and fatigue, are produced by considerable doses (Gubler). When a lethal dose is administered to an animal, its muscular system soon grows weak, and complete pa- ralysis soon after ensues. The voluntary muscular system, however, before complete resolution occurs, is agitated by a succession of tremors — temporary tetanic contractions followed by entire relaxation. These muscular tremblings occur, but more feebly, after complete paralysis, and persist in a slight degree after death. The muscular contractility is not destroyed, not even impaired, by physostigma. The irritability of the motor nerves is affected, if at all, to a very slight extent, and the sensibility of the sensory nerves is rather height- ened. It follows from these facts that the paralyzing effect of phy- sostigma is due to a direct action on the spinal cord. Attention has not thus far been directed to the influence of physo- stigma on the pupil. Whether introduced directly into the eye, or taken into the stomach, or thrown under the skin, it contracts the pupil. This is a local and peripheral action, exactly corresponding, as to its seat, to the action of atropine. The end-organs of the sympathetic, or of the motor oculi, and it may be of both, are acted upon. By some it is held that the contraction of the pupil is due to a tetanic state of the circular fibers (Grtinhagen, Rogow) ; by others, to a paralysis of the dilator system (Fraser, Hirschmann). It were probably safer to accept the conclusion that the nerves innervating both sets of fibers are acted on — the motor oculi stimulated (see case by T. Wharton Jones, " Practitioner," vol. iii), the sympathetic depressed — for we find that tetanic contraction of the muscular fiber of the intestine, followed by dilatation and a paretic state, can be experimentally produced by physostigma. The apparatus of accommodation is also affected ; myosis begins in ten to fifteen minutes after eserine is in- serted. Direct galvanization of the iris, contracted by physostigma, causes it to dilate (Engelhardt, Hermann). Thekapy. — The applications of physostigma to the treatment of disease are by no means so important as the elaborate study given to its physiological action, by various observers, would seem to indicate. In torpor of the muscular layer of the intestine, combined with deficient secretion of the mucous membrane, this agent is often very serviceable. In some subjects fifteen minims of the tincture, or a half- 576 MOTOR DEPRESSANTS. grain of the extract, taken at bedtime, will procure a morning evacua- tion, but it frequently fails. When the state to be relieved is such as is indicated above, a combination of physostigma, belladonna, and nux- vomica, is sometimes very effective : t> Tinct. physostigmatis, tinct. nucis vomicae, tinct. belladonnae, aa 3 ij.

To the troublesome flatulence of women at the climacteric period, usually associated with a paretic state of the muscular layer of the bowel, very great relief is often afforded by the use of physostigma. With the relief to the flatulence there usually follows relief to the morbid fancies, the headache and vertigo connected with it. The action of physostigma on the spinal cord, as a paralyzer, natu- rally suggested its use in tetanus. The evidence of its utility is dis- crepant. Moreover, tetanus, in many instances, manifests a tendency to spontaneous cure. It is difficult, therefore, to estimate the precise value of physostigma, but about one half of the cases treated with this agent recover — according to Watson, ten in eighteen ; according to Roemer, twenty in forty-seven cases. A larger measure of success might have been achieved, had sufficient attention been paid to the quality of the extract used and to the mode of administration. The following remarks by Dr. Fraser, in regard to the treatment of tetanus by Calabar bean, are of great importance : " I should myself feel inclined always to commence the treatment by subcutaneous injection, and to repeat such injection until the sys- tem is decidedly affected, and then to administer the remedy by the mouth in a dose three times as large as is found necessary by subcu- taneous injection. Such a plan might be quite safely followed in a child of even nine years. If the remedial effects continue to be pro- duced by administration by the mouth, it should be persevered with, for such administration has obvious advantages as far as the conven- ience of the practitioner is concerned. In the more severe cases, how- ever, I believe subcutaneous injection should be alone employed. The distress and increase of spasm caused by swallowing, or the im- possibility of introducing substances by the mouth, will render this necessary. I can not, also, too strongly urge that subcutaneous injec- tion should always be used when severe and continued spasms occur, when a fatal result is imminent from the exhaustion caused by pro- longed and frequent convulsions, and when apnoea threatens at once to close the tragic scene. By it we obtain the quickest and most pow- erful effect. "From the preceding remarks it can not be expected that any PHYSOSTIGMA. 577 arbitrary rules of dosage can be laid down. For an adult one grain of the extract by the stomach, or one third of a grain by subcutane- ous injection, will generally be sufficient to commence with. This should be repeated in two hours, when its effects will usually have passed off, and the succeeding doses may be modified according to the experience that will be thus gained. . . . The great object is to pro- duce as quickly as possible, and then to maintain, the physiological effect of physostigma in diminishing reflex excitability. The doses must, therefore, be continued in increasing quantities until this physi- ological effect is produced, or until the sedative action of the drug on the circulation is carried to a dangerous extreme, or until constant nausea and vomiting compel us to desist." Influenced by theoretical considerations, physostigma has been prescribed in chorea and epilepsy, but the results have not been en- couraging. It is true, successful cases of chorea have been reported, but the influence of favorable hygienic surroundings and time is so great in uncomplicated chorea, that we may well doubt whether phy- sostigma has any real influence. Of twelve cases of epilepsy treated by this agent, six were improved, and in the other six a notable in- crease in the number of the epileptic paroxysms took place (Williams). In progressive paralysis of the insane, remarkable improvement has occurred under the use of physostigma in a few cases (Browne), but in others the results have been entirely negative (Williams). As in this melancholy disorder no remedies have hitherto been of any avail, it is a gratifying fact that in some cases Calabar bean has seemed to stay its progress. Since it has been shown that physostigma lessens the activity of the respiratory function, lowers the action of the heart, and depresses the temperature, it has been used in bronchitis, congestion of the lungs, and pneumonia, with a degree of success which warrants more ex- tended and systematic use. Besides the various applications in ophthalmic practice growing out of the myosis produced by physostigma, it has been used with success in certain paralytic and convulsive states of the ocular muscles. In a case of paralysis of the third nerve, with ptosis, double vision, and immobile pupil, Wharton Jones effected a cure by the instillation of physostigma into the eye, whence he concludes that the myosis caused by this agent is due to the stimulation of the third nerve. Galezowski recommends the instillation of physostigma into the eye in cases of suppuration of the cornea and in amblyopia. Eserine disks (of gelatin) have been successfully employed in tic. The experiments — thirty in number — of the British Medical Asso- ciation Committee, with regard to the antagonism between physo- stigma and strychnine, have led them to the following conclusion : " Although the symptoms produced by either substance were mod- 37 578 MOTOR DEPRESSANTS. ified considerably by the action of the other, there was no instance of recovery from a fatal dose." The antagonism between atropine and physostigma, at least to a considerable extent, has been well established, especially by the labors of Fraser. In 1864 Klein wachter, influenced probably by the marked antagonism of the two agents on the pupil, employed physostigma with success in a case of poisoning by atropine. The British Asso- ciation Committee, however, conclude as the result of their investiga- tions that — "1. Sulphate of atropine antagonizes to a slight extent the fatal action of extract of Calabar bean ; 2. The area of antago- nism is more limited than even Dr. Eraser has indicated in his paper on the subject. "Thirty-one experiments, performed by the committee with hy- drate of chloral and Calabar bean, have shown that — " 1. Hydrate of chloral modifies to a great extent the action of a fatal dose of extract of Calabar bean, mitigating symptoms and pro- longing life. " 2. Hydrate of chloral, in some cases, saves life from a fatal dose of Calabar bean. " 3. If hydrate of chloral be given before extract of Calabar bean, so that the animal is deeply under the influence of hydrate of chloral before it receives the extract of Calabar bean, the symptoms pro- duced by the latter are much modified, and life is saved from the ef- fects of what would otherwise be a fatal dose. " 4. Chloral hydrate is of little service as an antagonist to extract of Calabar bean, if given some time after the latter. If the symptoms of the action of Calabar bean be in full operation, it will not save life, however it may modify symptoms." Uses of Eserine. — This alkaloid represents the powers of the plant, and is the most eligible form for internal administration, and for local use in ophthalmic therapeutics. Merck, however, maintains that the salicylate of physostigmine is the best preparation of the alkaloids, and it has been made official. The dose for internal and hypodermatic use ranges from -^ to -fa of a grain. Gelatin disks of eserine are now most frequently employed for instillation into the eye, but a neu- tral solution of any of its salts is convenient for this purpose. It is now largely used to counteract the effects of atropine on the pupil ; in iritis, to break away or prevent the formation of adhesions ; in ulcer- ation and suppuration of the cornea ; after extraction of cataract, to prevent suppuration (Wecker) ; in the operation of iridectomy. The curative influence of eserine in these cases is due to its action in low- ering the intra-ocular tension, in diminishing the conjunctival secre- tions by contracting the blood-vessels, and in checking the migration of the white blood-corpuscles (Wecker). Eserine may be substituted for physostigma for all purposes, by the stomach or hypodermatically. TOBACCO. 579 Authorities referred to : Arnstein tjnd Sustchinskt.

(Not official.) Composition. — Tobacco contains a powerful alkaloid — nicotine — in combination with malic acid. It is an oily, colorless liquid, strongly- alkaline in reaction. Its taste is hot and acrid, and its odor disagree- able and peculiar. It is contained in the dried leaves, in the propor- tion of about five per cent. Tobacco also contains a peculiar camphor — nicotianine. Tobacco-leaves are rich in mineral constituents — potash, lime, ni- trates, and phosphates. The vapor of tobacco "contains numerous basic substances of the picolinic series, and cedes to caustic potash, hydrocyanic acid, sulphureted hydrogen, several volatile fatty acids, phenol, and creosote" (Fltickiger and Hanbury, Husemann). It does not contain nicotine. The oil of tobacco is an empyreumatic product, obtained by distillation. Antagonists and Incompatibles. — The caustic alkalies, tannin, 580 MOTOR DEPRESSANTS. and the iodides, are chemically incompatible. Strychnine is, accord- ing to Haughton, a true physiological antagonist. Ergot, digitalis, belladonna, ammonia, and alcoholic stimulants, antagonize the effects of tobacco on the heart and arterial system. In cases of poisoning, the stomach should be evacuated by emetics or the stomach-pump, and tannin and the iodides should be adminis- tered. Ammonia and brandy are indicated to relieve the failing cir- culation. Subcutaneous injection of strychnine should also be resorted to, and, if necessary, artificial respiration. Synergists. — All of the motor depressants increase the effects of tobacco. Physiological Effects. — Tobacco is a severe and very depress- ing nauseant and emetic. It is locally an irritant to the mucous mem- brane, and produces burning pain at the epigastrium. It is also laxa- tive even when smoked, and in considerable quantity by the stomach causes hypercatharsis. The emetic effect of tobacco is, doubtless, the product of three factors : its cerebral action, its local irritation of the gastric mucous membrane, and its specific emetic property. The secre- tions of the intestinal mucous membrane are increased, and the mus- cular layer is thrown into tetanic contraction, whence the catharsis which follows its administration. Applied to a wounded surface, tobacco produces the same effects. Its active principle, nicotine, a crystalloidal substance, diffuses into the blood with great rapidity. It corresponds, in the mode and inten- sity of its action, to prussic acid. In a case narrated by Taylor, a fatal result ensued in three minutes after a toxic dose. In another case, death occurred in five minutes (M. Fougnies, poisoned by Count Bo- carme). When a lethal dose is administered to an animal, the action of the heart continues after respiration has ceased. Its cavities are usually found empty, or containing black fluid blood. Tobacco is not, therefore, a cardiac poison, and the depression of the circulation noted when full medicinal doses are administered is, doubtless, due to the interference with the pulmonary functions. Applied directly to the muscular tissue of the heart, nicotine does not impair its contractile power (Benham). The blood throughout the body is black and fluid ; but, as agitation with oxygen restores its color, and as the blood- globules are unaffected, the condition of the blood is doubtless due to the arrest of oxygenation (asphyxia). Trembling and clonic spasms are produced by lethal doses of to- bacco. Its ultimate effect is paralyzing, but preceding the muscular relaxation and paresis there is in animals, and occasionally in man, a definite tetanic stage. Death ensues through its paralyzing action on the muscles of respiration. The end-organs of the motor nerves lose their excitability, next the trunks of the nerves, and then the spinal cord, but the muscular irritability is unaffected. The brain is not TOBACCO. 581 directly affected. Giddiness and delirium have been noted in cases of poisoning by tobacco, but these symptoms, as well as the insensibility which immediately precedes death, are no doubt due to the accumu- lation of carbonic acid in the blood. The pupils are contracted by tobacco, and, in fatal cases, are insensible to light. There is considerable sweating, and the skin is cold and clammy in fatal cases. The temperature of the body is decidedly reduced (Tsches- chichin). The elimination of nicotine probably takes place by the kid- neys. Yery free urinary discharge, at all events, is produced by to- bacco, and, reasoning by analogy, it may be supposed that this effect is due to the direct action of the nicotine on the Malpighian tufts and on the tubules of the kidneys. When a lethal dose of nicotine has been taken, and the effects fol- low immediately, there may be none of the symptoms described above. In the case narrated by Taylor, the " deceased stared wildly ; there were no convulsions, and he died quietly [in three minutes], heaving a deep sigh in expiring." Therapy. — In habitual constipation, due to a relaxed state of the muscular layer of the bowel, five minims of the wine of tobacco, ad- ministered at bedtime, will not unfrequently afford relief. Impaction of the coscum, colica pictonum, sometimes intussuscep- tion, and strangulated hernia, may be overcome by a tobacco-enema. It must be borne in mind, however, that this is an expedient not free from danger. Numerous deaths have been caused by it, and Dr. Cope- land reports one instance in which thirty grains by enema proved fatal. Of the official infusion ( 3 ]* — Oj) it is not safe to use more than four ounces, or fifteen grains ; and this quantity may be expected to pro- duce most depressing nausea. It must be urged in favor of this remedy that it has, in very unfavorable cases, proved exceedingly effective. It is especially adapted to cases in which obstruction has occurred from paresis of the muscular layer of the bowel (impacted caecum, typhlitis, painter's colic). Tobacco is one of the antispasmodic remedies used in the treatment of spasmodic asthma, and the paroxysms of difficult breathing in em- physema. It enters as a constituent in various pastilles and cigarettes employed in these maladies. Asthmatics, unaccustomed to the use of tobacco, are sometimes relieved by smoking a cigar or pipe, but the effect is lost by habitual use. Laryngismus stridulus may be quickly arrested by a snuff -plaster to the neck — an effective but dangerous domestic remedy. Obstinate hiccough, or singultus, may be cured by five-minim doses of wine of tobacco, but we possess other useful reme- dies, less dangerous and less unpleasant in action. We possess no remedy more effective in the treatment of tetanus than tobacco. It may be used in the form of an enema, commencing with four ounces of the infusion, and regulating the quantity to be 582 MOTOR DEPRESSANTS. administered and the time of administration by the effect produced. Minim-doses of the alkaloid may be given every two hours by the stomach, or two minims by the rectum (Haughton). When it acts favorably, it relaxes the trismus so that nutriment may be taken, and suspends the tonic convulsions. Care must be used not to introduce a lethal quantity, and produce death by asphyxia. The author has known the wine of tobacco to be used successfully in a severe case of tetanus, the quantity administered being regulated by the effect of the remedy on the convulsions. The experiments of Haughton having demonstrated an antagonism between nicotine and strychnine, he proposed the use of nicotine in stryclmine-poisoning, and cases have occurred in which it proved en- tirely successful. As the effects of nicotine are so nearly instantane- ous, the stomach administration — if the spasms do not prevent — will suffice, but rectal and even hypodermatic injections may be resorted to if necessary. The following formula of Erlenmeyer may be used for the subcutaneous injection in strychnine-poisoning and in tetanus : ^ Nicotinse, gr. ss ; aquae destil., 3 ij. M. Sig.: Ten minims contain yz of a grain. The cases of strychnine-poisoning in which tobacco was used successfully were treated by the infusion. Tobacco was formerly employed in the treatment of dropsy. It is adapted to those cases in which digitalis is now used. It promotes free diuresis, and is at the same time laxative — effects especially serviceable in cardiac dropsy. It is, however, so disagreeable in action that few practitioners have the temerity to prescribe it, and few patients are willing to swallow it. There is no doubt that excessive use of tobacco lessens the venereal appetite. Slightly nauseating doses of the wine of tobacco will check chordee and priapism. Satyriasis is effectively quenched in tobacco- nausea. Nocturnal pollutions, due to repletion and to continence, are also usually suspended by the use of this remedy ; but it is, unfor- tunately, so horribly depressing that the remedy may be justly con- sidered the greater evil. Local Uses of Tobacco. — So many unfortunate accidents have re- sulted from the external application of tobacco, that its use in this way is rarely justifiable. The infusion and an ointment have been employed with success in tinea, scabies, prurigo, pityriasis, etc. An injection of tobacco will destroy ascarides, but it is unsafe. Other and more manageable remedies have entirely taken the place of tobacco in the local diseases above named. Authorities referred to : Benham, Dr. W. T. On the Action of Nicotine.

Composition. — The effects of lobelia are due to the presence in it of a peculiar alkaloid — lobeline. This principle is oily in consistence, has a pungent, rather acrid taste, a tobacco-like odor, and is strongly alkaline in reaction. It is slightly soluble in water, but more freely soluble in alcohol and ether. It combines with acids to form crystal- lizable salts, which are soluble in water and in alcohol. The active principle — lobeline — is combined in the plant with lobelie acid. Antagonists and Incompatibles. — The caustic alkalies decom- pose lobeline ; hence these are incompatible. The depressing effects of lobelia on the circulation are counteracted by digitalis, belladonna, ergot, and other vaso-motor excitants, by alcohol, ether, ammonia, etc. ; on the nervous system of animal life, by strychnine, picrotoxin, thebaine, etc. Synergists. — All of the motor depressants increase the effects of lobelia. Physiological Actions. — The taste of lobelia is pungent and acrid, and it persists for a long time in the fauces. The leaves chewed excite a very abundant flow of saliva, and soon cause a feeling of epigastric 584 MOTOR DEPRESSANTS. depression and nausea, with giddiness and headache. The preparations of lobelia administered by the stomach produce, in considerable doses, a degree of nausea and depression which amounts to anguish. An abundant outpouring of gastric mucus takes place, and vomiting en- sues, with great straining and distress. The action of the heart is enfeebled ; headache and vertigo are experienced ; a profuse sweat breaks out on the surface of the body ; the intestinal canal is relaxed, and the discharge of urine is increased. «> When a lethal dose is taken, especially if vomiting do not occur, the effects are chiefly expended on the nervous system of animal life. Muscular weakness and trembling, shallow respiration, coldness of the surface, feeble circulation, insensi- bility, and sometimes convulsions, have occurred. Death ensues from paralysis of the muscles of respiration — the action of the heart contin- uing after respiration has ceased. The insensibility is doubtless pro- duced in the same way as by tobacco, and the cerebral effects are not the result of a direct action of the poison. According to the investigations of Ott, lobeline, in moderate doses, first " increases the blood-pressure by acting as an excitant on the peripheral vaso-motor nervous system." This primary effect is not of long duration, a fall in the blood-pressure soon occurs, the peripheral circulation is so embarrassed from weakened power of the heart, and obstructed pulmonary circulation, that oxygenation of the tissues is rapidly impaired, and a marked reduction of temperature takes place. Lobeline affects chiefly the motor nervous system, and especially the medulla oblongata and its respiratory center (nucleus of pneumo- gastric). Therapy. — Lobelia is much employed by the self-styled physio- medical practitioners as a " sanative agent." The great quantity of mucus discharged from the stomach under its emetic action is consid- ered by them a proof of its power as an eliminating agent. As an emetic, lobelia is entirely too harsh and depressant to justify its use for this purpose. In habitual constipation, dependent on atony of the muscular layer of the bowel and deficient secretion of the mucous membrane, good results are sometimes obtained by small doses of the tincture — ten minims — administered at bedtime. Impaction of the cmcum, when inflammation has not occurred, may be removed, and the bowels induced to act, by small doses, frequently repeated, of the tincture of lobelia (two drops every hour). This remedy can be used when purgatives would produce serious mischief. An infusion of lobe- lia as an enema has succeeded in relieving strangulated hernia, intus- susception, and fecal impactions. This use of the agent is the same as for the corresponding administration of tobacco ; it is much safer than tobacco, and may be used to produce as decided therapeutic effects. Unquestionably the most important application of lobelia is to the treatment of the asthmatic paroxysm. It gives relief in a few minutes HYDROCYANIC ACID. 585 to violent attacks of spasmodic asthma, and it sometimes happens that the relief is permanent. Frequent repetition of this remedy in the same individual, however, lessens its effects, and it may finally cease to afford any relief. To be effective in asthma, a teaspoonful dose of the acetum or tincture must be administered every fifteen minutes until nausea is induced. Free expectoration and abundant gaseous eructa- tions take place, and the breathing soon becomes easy and calm. The efficiency of lobelia is increased by the addition of iodide and bromide of ammonium. IJ Tinct. lobelias, § j ; ammonii iodidi, 3 ij ; ammonii bromidi, 3 iij ; syrup, tolutan., § ij. M. Sig. : A teaspoonful every one, two, three, or four hours. Whooping-cough, especially after the cessation of the catarrhal stage, has been treated successfully by lobelia, but we now possess other agents more effective and less disagreeable in action. Lobelia is, however, an excellent expectorant. It is adapted to cases in which the cough is dry, resonant, and spasmodic. It succeeds best in those who have attacks of cough with spasmodic difficulty of breathing, and who get up a little tough mucus after long and painful paroxysms of coughing. A lobelia-emetic will cut short an attack of spasmodic croup, but it is too harsh and dangerous a remedy to be employed for this pur- pose. Lobelia may be used instead of tobacco in tetanus, strychnine-poi- soning, and allied states. Authorities referred to : Fluckiger and Hanbury. Pharmacographia, p. 357. Ott, Dr. J.

It imparts a faint, evanescent red color to litmus, and is not discol- ored by hydrosulphuric acid. With solution of nitrate of silver, added in slight excess, one hundred grains of it produce a white precipitate, which, when washed with water until the washings are tasteless, and dried at a temperature not exceeding 212°, weighs ten grains, and is wholly soluble in boiling nitric acid. The official diluted acid contains two per cent of anhydrous acid and ninety-eight per cent of alcohol and water. (U. S. P.) Dose, Tf[ j — ni v. Antagonists and Incompatibles. — The metallic salts are, gener- 586 MOTOR DEPRESSANTS. ally, incompatible ; also the red oxide of mercury and the sulphides. Freshly-precipitated oxide of iron (hydrated sesquioxide) has been proposed as a chemical antidote, but its action is too slow. In cases of poisoning, the remedies of the greatest utility are cold affusion to the spine, the inhalation of ammonia, the stomach administration, as also the intra-venous injection of this substance, and the subcutane- ous injection of ether. Atropine has been proposed as a physiological antagonist by Preyer ; but the rate at which atropine is diffused, as compared with the diffusion of prussic acid, obviously will render such antagonism powerless, how much soever it may be approved on theoretical grounds. The results of experiments, as the author and others have shown, are, however, opposed to the existence of this antagonism. In addition to these measures, artificial respiration should be practiced. Physiological Effects. — Applied to the unbroken skin, it is doubtful whether hydrocyanic acid is absorbed, but in contact with a wound or an abrasion, and with the mucous membrane, it diffuses into the blood with great rapidity. The vapor has a rather fragrant odor, similar to that of bitter al- monds. Inhaled, it has speedily caused death. When the effects of the vapor are short of lethal, giddiness, faintness, embarrassed breath- ing, a weak, small pulse, and great muscular weakness, are produced ; and there may be even coma and profound insensibility, and yet re- covery ensue (Taylor). In small medicinal doses, beyond a fugitive and very slight calma- tive effect, no symptoms are produced by it. When the dose some- what exceeds the medicinal standard, there may occur transient gid- diness, nausea, faintness, a feeble pulse, and general muscular weak- ness. The effects follow very speedily. When a very large toxic dose is taken, a few seconds only intervene from the act of swallowing until its effects are manifest, and death may ensue in two minutes or be postponed to five. Under these circumstances, the following phe- nomena have been observed : sudden insensibility ; eyes protruding and glistening ; pupils dilated and unaffected by light ; extremities cold, relaxed ; the skin covered with a clammy sweat ; breathing con- vulsive, slow ; the pulse extremely feeble or imperceptible ; evacua- tions involuntary (Taylor). When the effects are slower, in conse- quence of the ingestion of a merely lethal dose, there are occasionally tetanic convulsions, opisthotonos, trismus, etc. Although the effects of prussic acid are exceedingly rapid, a fatal result is not instantaneous. Various acts of volition may be gone through, provided but a few seconds are required for their perform- ance. Several instructive instances of this kind are narrated by Tay- lor. The effects of hydrocyanic acid are not more rapid than can be accounted for by its distribution through the blood. HYDROCYANIC ACID. 587 Most contradictory opinions have been expressed as to the action of prussic acid on the blood : that it at first arterializes and afterward arrests decarbonization of the blood ; that it destroys the ozonizing power, and does not impair the capacity of the red blood-globules to carry and to yield up oxygen ; that cyanohaemoglobin is formed by the combination of the acid with haemoglobin, and that this combina- tion can not take place, owing to the rapidity of the action of the poison. From this chaotic state of scientific opinion the following may be evolved : the blood is dark, owing to deficient decarbonization, but this is probably due to a spasm of the pulmonary arterioles and paresis of the muscles of respiration, whence it follows that rapid as- phyxia ensues. The primary action of prussic acid on the terminal filaments of the pneumogastric, as shown by Preyer, is confirmatory of this view. Although the action of the heart ceases after respiration, prussic acid undoubtedly exerts a direct paralyzing action on the cardiac ganglia. The cerebral effects of this poison are, probably, indirect, the re- sult of rapid carbonic-acid poisoning, and the sudden withdrawal of oxygen from the cerebral tissues. Direct application of prussic acid to the medulla oblongata causes (in the alligator) a sudden and com- plete expiration, and collapse of the lung (Jones). The tetanic con- vulsions which have been observed in many cases of poisoning, in ani- mals and in man, indicate a direct action of this agent on the spasm- center ; but the disappearance of the excitability of the motor nerves, and of the contractility of muscles which it causes, shows that it quickly exhausts the irritability of the spinal cord. These effects on the cord, on the nerve-trunks, and on the muscles, are also, probably, in part due to the circulation through them of blood deprived of oxy- gen and charged with carbonic acid. The fact that instances of re- covery from a condition of profound insensibility are numerous, is con- firmatory of the view just expressed. Moreover, artificial respiration exerts an undeniable influence over the lethal effects of the acid in ani- mals (Preyer), whence it may be concluded that to supply oxygen to the blood is sufficient to arrest all of the symptoms produced by the want of oxygen and by the excess of carbonic acid. Post-mortem rigidity sets in early after death from prussic acid, and is very pronounced. The fingers are tightly closed, the toes strongly flexed, the jaws rigid, the eyes prominent and staring. The blood is dark-colored, fluid, and the venous trunks and the cerebral sinuses are gorged. The quantity of medicinal, diluted hydrocyanic acid necessary to produce death will vary with the age, size, and bodily vigor. Habit, also, influences to a remarkable degree the susceptibility to its toxic influence. A quantity equivalent to forty minims of the diluted hy- 588 MOTOR DEPRESSANTS. drocyanic acid (United States Pharmacopoeia) has proved fatal. As the effects of a medicinal dose are expended in a half hour to one hour, the repetition of the doses hourly will not be unsafe. Hydrocyanic acid is not a cumulative poison. Theeapy. — Hydrocyanic acid is a remedy of very considerable util- ity in certain affections involving the functions of the pneumogastric nerve. It is often highly serviceable in various kinds of nervous vom- iting ; for example, the vomiting of pregnancy, the vomiting which accompanies some cerebral disorders, and the reflex vomiting of phthi- sis. The good effects are quickly, if at all, produced ; hence, if no result is attained after some days' administration, no advantage can be expected from its continued administration. 3 Acid, hydrocyan. dil., 3 j ; aquae laur.-cerasi, 1 ij. M. Sig. : A teaspoonfid every two to four hours. Gastralgia, when it is a truly neuralgic affection of the gastric nerves, is occasionally very quickly cured by this agent. Sometimes cases, apparently in every way suitable for its use, are not improved by it. If a few doses do not effect any amelioration, it will be useless to continue it. Cases of indigestion accompanied by pain in the nucha, and attacks of giddiness (stomachal vertigo), are sometimes re- markably relieved by prussic acid. Irritative dyspepsia, manifested by these symptoms, a red-glazed tongue, pain, epigastric tenderness, and a feeling of weight and oppression, may be, not unfrequently, much benefited, and, indeed, cured ; but while the results are often brilliant, failures are also frequent. Enteralgia, a malady often ex- tremely rebellious to remedies, not unfrequently yields promptly to prussic acid. Considerable medicinal doses of this agent are very fatal to round worms (lumbricoides). Hydrocyanic acid is a successful remedy in whooping-cough, after the subsidence of the catarrhal symptoms. It acts by allaying irrita- bility of the pneumogastric, and is successful just in proportion to the preponderance of the nervous symptoms. The cases in which the au- thor has witnessed the best results were cases of cough by habit, after the cessation of the whooping-cough proper. The nervous cough of mothers, which exists during the presence of whooping-cough in the household, may be allayed by this agent.

It some- times happens that this agent will greatly relieve the cough of phthisis, but only when it is chiefly nervous. To allay cerebral irritation and excitement, prussic acid has been employed with benefit (McLeod). In forty cases of mental disorder ob- served by McLeod, there was "slight or temporary amelioration" in CYANIDE OF POTASSIUM. 589 ten ; a " more decided and permanent effect," the disease being still sta- tionary or progressive, in nineteen ; and in eight cases, six of acute mania, and two of acute melancholia, " the drug has been a factor, and a very main one, in rapid restoration to reason." In the treatment of these cases, McLeod used from two to five minims of Scheele's dilute acid, which contains five per cent of anhydrous acid. His method of administration consisted in giving it at first at short intervals (every quarter of an hour), and, when effects were produced, every hour or two. He also employed it subcutaneously, in five-minim doses. External Uses. — In various cutaneous diseases characterized by itching, the local application of prussic acid affords relief.

Physiological Actions. — The effects of this salt have been already mentioned in sufficient detail in the preceding article, so far as they correspond to hydrocyanic acid. It has, however, some special physical 590 MOTOR DEPRESSANTS. properties which separate it slightly from the powerful agent which en- ters into its composition. Applied to the unbroken epidermis, the cyanide of potassium produces at first a sensation of coldness, followed by tingling and itching, and in a half-hour the skin is found to be somewhat red- dened. Prolonged contact produces a phlyctenular or eczematous eruption. Systemic effects are produced by the local and external use of the cyanide of potassium, viz., slowing of the pulse and respiration, mus- cular weakness, drowsiness, and coldness. Lethal effects may follow prolonged contact with the skin, even when the epidermis is unbroken. Applied to a wound or abraded surface, this salt causes a burning pain, excites a high degree of inflammation, and produces prompt lethal effects. Therapy. — Cyanide of potassium may be prescribed as a substitute for hydrocyanic acid in all of the maladies for which the latter is used. This salt has, however, some special applications which we owe to Trousseau. This eminent observer has shown that a solution of the cyanide applied to the seat of painful sensations gives great relief in various forms of reflex headache, gastric, cardiac, pulmonary, and men- strual. The headache which accompanies the pyretic state is, accord- ing to the same authority, cured or greatly alleviated by the cyanide solution, while at the same time a favorable influence is exerted over the temperature. $ Potassii cyanidi, gr. x — 3 j ; aquae lauro-cerasi, § iv. M. Sig. : A compress, moistened with the solution, to be applied to the seat of pain. From a quarter to a half hour of contact with the skin usually suffices. A solution of the cyanide of potassium, of the strength given above, will remove the stains of nitrate of silver, and also the dissecting-room odor, from the hands. Cyanide of potassium, in the form of ointment or solution, is an ex- cellent remedy for allaying irritation in various cutaneous diseases. In pruritus and urticaria, the following formula (McCall Anderson) gives relief : fy Potassii cyanidi, gr. vj ; pulv. cocci, gr. j ; ung. aq. rosse, § j. M. Sig. : Ointment.

JVitrite cVamyle, Fr. ; Amylni- trit, Ger. Properties. — A yellowish or reddish-yellow liquid, rather oily in consistence, very volatile, and having a peculiar and very diffusive ethereal odor. It is insoluble in water, but soluble in all proportions in alcohol, ether, chloroform, benzol and benzin. It has a neutral or a slightly acid reaction. It may contain, as impurities, nitric acid, amyl- nitric ether, amylvalerianic ether, and hydrocyanic acid. The specific gravity is "877. Dose, ttj, ij — ttj, v, by inhalation or subcutaneously. Antagonists. — The actions of the nitrite of amyl are antagonized by all those agents which increase the functional activity of the spinal cord and sympathetic — as strychnine, brucine, picrotoxin, digitalis, ergot, belladonna, and, as McCullough has shown, it is an efficient remedy in chloral - poisoning. The opposing action of amyl nitrite and ergot has been demonstrated clinically by Dr. Fancourt Barnes, in cases of hour-glass contraction induced by ergot. This antago- nism may not be available, owing to the difference in the rate at which they are diffused, to affect the system. Synergists. — All of the motor depressants increase the effects of the nitrite of amyl. Physiological Actions. — The following are the symptoms pro- duced by nitrite of amyl when inhaled : acceleration of the action of the heart ; sudden flushing of the face ; dilatation of the arterioles in consequence of paresis of the muscular layer of these vessels ; a sense of extreme fullness of the brain, with vertigo ; fall in the blood- pressure ; lowering of the temperature ; complete resolution of the muscular system of animal life. The vapor of nitrite of amyl ap- plied directly to the tissues — muscular or nervous — suspends or com- pletely arrests functional activity. Circulating in the blood, it un- doubtedly affects most the vaso-motor nervous system and unstriped muscular fiber. The marked acceleration of the heart (Pick) is in part consecutive, doubtless, to the sudden dilatation of the arterioles, permitting such an increased quantity of the blood to enter these vessels as to require renewed effort on the part of the heart to supply it ; in part also to the paretic state which it induces in the inhibitory apj:>aratus. The great fall in the blood-pressure noted by Brunton, Wood, and Amez- Droz, is also due to dilatation of the arterioles, and consequent dimi- 592 MOTOR DEPRESSANTS. nution of tension in the peripheral vascular system. Dilatation of the retinal vessels, when nitrite of amyl is inhaled, has been ascer- tained by ophthalmoscopic examination (Aldridge). On the nervous system of animal life the nitrite of amyl acts as a depressant — impairing motility first, and, at the last, sensibility. It affects both the spinal cord and the nerves, lessening the sensibility to all forms of irritation, and diminishing the reflex functions. It also impairs the contractility of muscle. Death ensues from failure of res- piration, and the cerebral functions are unaffected until carbonic-acid poisoning ensues. Decided lowering of temperature is produced by the nitrite of amyl. This result is no doubt due to the action of this agent on the haemoglobin, whereby the carrying capacity of the red blood-glob- ules of oxygen is lessened (Gamgee), metamorphosis of tissue is in- terfered with, and the generation of animal heat is diminished. A peculiar change ensues in the color of the blood as a result of the lessened oxygenation : all the blood of the body assumes a modified venous hue. A curious fact has been noted by Hoffmann, viz. : the hypoder- matic injection of lethal doses of nitrite of amyl produces in rabbits a temporary glycosuria. Therapy. — The applications of the nitrite of amyl in the treat- ment of disease have been deduced from a study of its physiological actions. It is especially indicated when morbid symptoms result from vaso-motor spasm. It has been shown that epileptic attacks may be warded off by the inhalation of nitrite of amyl at the begin- ning of the movement of the aura. Patients who have a distinct warning of the seizures should be constantly provided with a small quantity of this remedy in order to practice the inhalation whenever an attack is impending. The mechanism of the action is very simj)le : the vaso-motor spasm of the cerebral vessels, which is the initial symptom of an epileptic convulsion, is relaxed, and the vessels dilated by the nitrite of amyl. By the timely inhalation of the nitrite, the cold stage of an ague may be aborted, but the hot stage is not modified in any way (Price, Ziegler). This power may be most serviceable in cases of pernicious intermittent, the danger of which consists in the extreme depression of the cold stage. The cardiac failure caused by chloral, chloroform, and other heart-poison, and the condition of sudden weakness which may ensue from various causes, in cases of fatty heart, are often re- markably relieved by the inhalation or hypodermatic injection of amyl nitrite. An attack of migraine, of that form characterized by vaso-motor spasm (pallor of the face), may be quickly relieved and sometimes aborted by the inhalation of two or three drops of amyl nitrite. NITRITE OF AMYL. 593 When there are redness of the face, injection of the conjunctivae, and fullness of the cerebral vessels, this remedy is contraindicated. Cases of neuralgia of the fifth nerve, second division, have been cured by inhalation of amy], repeated from time to time as the pain required its administration. Asthma, when purely spasmodic, is usually quickly checked by this remedy. The paroxysms of difficult breathing which accompany emphysema and cardiac disease are not relieved in this way ; indeed, the author has known the most serious distress to be produced by the inhalation under these circumstances. Exaltation of the reflex function of the spinal cord and muscular spasm are morbid states in which good results may be expected from inhalation of the nitrite of amyl. It has been used with success in tetanus. It should also be fairly tried in strychnine-poisoning and in hydrophobia. Michael has administered it in tinnitus aurium, a most obstinate and distressing condition, with comparatively good effects : of a group of thirty-three cases, nineteen were distinctly benefited. Most signal relief has been obtained from the inhalation of amyl nitrite in angina pectoris. We owe this important suggestion and practice to Brunton, who had ascertained that when the paroxysm of angina pectoris occurs, a great rise of arterial tension takes place. When the pain, precordial distress, and anxiety are felt, there should be no delay in the use of the remedy. Some cautions are, however, needed. It may be unsafe when advanced degeneration of the cere- bral vessels exists (Anstie). Fatty degeneration of the heart, which is so frequently a cause or an accompaniment of angina pectoris, may also render the use of so powerful a paralyzer of doubtful expediency. Dr. Mary Putnam Jacobi has found the inhalation of nitrite of amyl very serviceable in neuralgic dysmenorrhea. As an antagonist to ergot, it may prove in a high degree useful, when ill effects are caused by this remedy. Thus, in a case of hour-glass contraction pro- duced by ergot, the inhalation of amyl nitrite procured immediate re- lief. On theoretical grounds this agent was proposed for the relief of cholera asphyxia (Brunton, Gamgee), but the trials thus far made with it have demonstrated its inutility. Owing to the fact, shown by Gamgee, that nitrite of amyl combines with haemoglobin, Brunton pro- poses that this remedy, if given at all in cholera, must be administered by the stomach or by subcutaneous injection, and not by inhalation. Repetition in the use of the nitrite of amyl diminishes its effects, and hence increasing doses are necessary when it is often employed in the same case.

Properties. — Nitro-glycerin is an oily liquid, colorless, or pale yel- low, and has the specific gravity 1*60 at 59° Fahr. It burns quietly in the open air, but heated in a close vessel, or subjected to percussion, it explodes violently. It decomposes if long kept. It is very slightly soluble in water, but dissolves freely in alcohol and in ether. The best preparation for administration is the alcoholic solution — one part of nitro-glycerin to one hundred parts of alcohol. The dose of this ranges from one minim to many minims. As the susceptibility to this agent varies greatly, the initial dose should be the smallest. One minim of the one-per-cent solution will give some persons violent headache, while others may take a minim of the undiluted drug with- out any decided effect. It should not be forgotten that the alcoholic solution will explode if struck with a wet hammer. Sodii Nitris. — Nitrite of soda. JPotassii Nitris. — Nitrite of potassium. These salts have been pro- posed and used as substitutes for amyl nitrite and nitro-glycerin. Dose, g r - iij— gr- viij. Ethyl nitrite is the most important constituent of nitrous ether. Inhaled, it has effects similar to the other nitrites. Antagonists. — All those agents which increase the reflex activity of the spinal cord and stimulate the vaso-motor system, as strychnine, ergot, digitalis, belladonna, etc., antagonize nitro-glycerin. Synergists. — Amyl nitrite acts very similarly, and the motor de- pressants in general promote the actions of nitro-glycerin. Physiological Actions. — The taste of nitro-glycerin is at first sweetish, but this impression is followed by aromatic pungency. In a few minutes — from three to five — after a small medicinal dose, there are suddenly experienced a feeling of giddiness, tension of the head, with fullness, languor, nausea, and sometimes stomach - pain. Such effects are experienced from a small dose, if the individual taking it is susceptible. It follows, then, that the quantity of nitro-glycerin causing such symptoms must vary in different patients. Dr. Harley experienced these effects after taking fifteen drops. Dr. Fuller expe- rienced some fullness of the head, perspiration, intermittent pulse, and some after-headache, from a dose equivalent to fifty minims of a one- NITRO-GLYCERIN. 595 per-cent solution, or a half -drop of the nitro-glycerin itself (Murrell). In some persons a drop or two of the one-per-cent solution will cause dizziness, faintness, a rapid and very weak pulse, perspiration of a rather clammy character ; or, indeed, the symptoms may proceed to unconsciousness. Dr. Murrell applied the moistened cork of the bottle containing the solution to his lips, and in a few minutes experienced a tremendous action of the heart and arterial system ; his pulse rose to 100 and higher, and he had " a splitting headache " for some time. There is no change in the temperature. Women and the feeble in constitution suffer more decided effects than the robust. Drowsiness comes on, with a feeling of languor, in those on whom the smallest dose acts kindly. With the rapid pulse is a considerable degree of dicrotism. The change in the character of the pulse begins in about six minutes after the dose is taken, and lasts on the whole about one hour. The sphygmographic tracings appended to Dr. Murrell's paper are remarkable for the extent of the excursions of the lever, the ab- rupt ascent, the sharpness of the summit, and the dicrotic rebound, in- dicating an extremely low state of the arterial tension. When the heart of a frog is put into a '75-per-cent salt solution, and two drops of a ten-per-cent solution of nitro-glycerin are added, the heart acts more and more slowly, and presently stops. An alcoholic solution has no effect (Brunton). When injected into the jugular vein of a cat, the nitro-glycerin solution arrests the heart speedily. That the vagus is paralyzed, and the inhibition thus removed from the heart, is proved by the fact that galvanic excitation of the vagus has no effect in restraining the cardiac movements. Changes occur in the blood like those induced by amyl nitrite and the nitrites of soda and other nitrites ; that is, the blood assumes a chocolate-color, and probably loses its power of absorbing and conveying oxygen ; but its so-called ozonizing function may not be interfered with, since nitro-glycerin does not prevent the guaiac reaction, in which respect it agrees with the other nitrites. The change in the color of the blood is produced slowly when blood is shaken up with some nitro-glycerin outside of the body (Brunton). In frogs nitro-glycerin causes weakness, tetanus, ending in paral- ysis ; but, in warm-blooded animals, there are convulsive movements, as twitching of the muscles, hiccough, spasmodic breathing, etc. The tetanus in frogs, according to Brunton, is not due to a direct action of the poison on the spinal cord, thus opposing the assumption of Minor, who held that it acts on the medulla. The paralyzing effect of nitro- glycerin appears to be due to an action on the muscles, and also on the motor nerves. When it is applied directly to the muscles, they quickly lose their contractility. The reflex function of the cord is extinguished first in the parts external to the cranium, the cerebral nerves preserving their power to transmit impressions until later. Sen- 598 MOTOR DEPRESSANTS. sation is destroyed by it as well as motility. Death is due to asphyxia — to paralysis of the muscles of respiration. Notwithstanding the activity of nitro-glycerin, the most serious symptoms are recovered from without detriment. Thus Dr. Murrell narrates several cases in which unconsciousness was produced without any ill results, except some temporary headache. THEEAPY.^-Nitro-glycerin is adapted to the treatment of the mala- dies in which its congener, amyl nitrite, has proved so effective. It has the advantages over the latter of being more permanent, more readily administered, and more sustained in action. In sea-sickness, reflex vomiting, gastralgia, hepatic colic, and other painful and spas- modic affections of the digestive tube, it may afford very prompt re- lief. It was first employed in the treatment of angina pectoris, in which it gives as much relief as does amyl nitrite, but the latter should be preferred when the utmost promptitude of action is necessary. The form of the disease requiring this medicine is that characterized by high tension of the peripheral vessels, which is doubtless the condition in the genuine cases of angina pectoris. Yery prompt relief may be given to attacks of hiccough by this medicine. Some cases of spas- modic asthma are much benefited by it. The less there is of struc- tural alterations, the more certain the relief. As the secretions of the mucous membrane of the respiratory tract are increased by it, the cases with deficient secretion are those most certain to be benefited. It should be carefully tried in whooping-cough and in laryngismus stridulus. There is much to be expected from nitro-glycerin in dis- eases of the nervous system characterized by heightened reflexes. An attack of epilepsy may be aborted by its timely administration, and Hammond finds it as a remedy for this disease second only to the bro- mides. By preventing the spasm of the vessels and consequent sud- den anaemia of the brain, the first and most important event in the series can not occur. It should be fairly tried in tetanus and hydro- phobia. In neuralgia of the fifth nerve it has given immediate relief in numerous instances. It is the most appropriate remedy in that form of migraine, or sick-headache, in which the vessels are in a condition of spasm, but is not proper in those cases having a flushed face from dilated vessels. The cold stage of an intermittent may be aborted by the timely administration of nitro-glycerin. It promises to be especially useful in the pernicious malarial diseases to prevent the dangerous depression of the cold stage. In these cases its administration should be so timed that the physiological effect of the remedy occur at the onset of the cold stage of the disease. The mechanism of its curative action is obvious. Remarkable results have lately been obtained from this remedy in acute and chronic Brighfs disease (Robson) — results which the author is able, from personal observations, to confirm. It is well ACONITE. 597 known, of course, that high arterial tension is present ; but whether as causative of the renal changes, or a consequence of them, is not known. The apparently constant association of degenerative changes in the renal ganglia with the lesions of Bright's disease, discovered by Da Costa and Longstreth, would indicate that the state of the vessels is a factor in developing the structural alterations. The manner in which nitro-glycerin affords relief, and possibly effects a cure, is thus fully explained. Indeed, all of the curative results obtained from nitro- glycerin must be referred to its action on the vascular apparatus. Authorities referred to : Brunton, T. Lauder.

Composition. — The principal alkaloid is aconitia or aconitine, which exists in two forms, crystalline and amorphous, and forms with acids cry stalliz able salts. The crystalline form of aconitine is soluble in chloroform, ether, and alcohol. Aconite contains also another alka- loid which has received various designations — pseuclo-aconitine, na- pelline, nepalline, etc., which is closely allied to aconitine, and is found in commerce under this name. It is but slightly soluble in chloro- form, ether, and alcohol, and it exists also in two forms, crystalline and amorphous. Besides the foregoing, another base has been dis- covered, to which the name napelline has also been given (Hiibsch- mann). This is an amorphous alkaloid, having strong basic proper- ties, soluble in water, chloroform, and alcohol, but not soluble in ether. These basic substances are united with a peculiar acid — aconitic acid. Antagonists and In compatibles. — Alcohol, ether, ammonia, tur- pentine, digitalis, heat, etc., antagonize the actions of aconite. In cases 598 MOTOR DEPRESSANTS. of poisoning, the stomach should be evacuated, stimulants adminis- tered by the stomach and rectum, and external warmth applied. Digi- talis has been used with considerable advantage (Fothergill). The intra-venous injection of ammonia may be practiced, and artificial res- piration resorted to. To overcome the depression of the heart's ac- tion, which is the capital point, the hypodermatic injection of atropine is indicated. As the chief danger consists in failure of the heart's ac- tion, the recumbent position should be strictly maintained. Synergists. — All the agents of this group increase the effects of aconite. Cold, fatigue, and all depressing emotions, are also syner- gistic. Physiological Actions. — A drop of tincture of aconite placed on the tongue excites a warm and pungent sensation, followed by persist- ent tingling and numbness. Prolonged contact with the skin causes similar effects upon the sensory nerves. During the medicinal adminis- tration of aconite in considerable doses, irritation and a sense of constric- tion of the fauces are experienced. Large medicinal doses produce gastric pain, nausea, and even vomiting. When the gastro-intestinal mucous membrane is in an irritable state, aconite impairs the appetite, hinders the digestion, and causes diarrhoea, and in the normal state of the membrane, increases its secretions and hastens the peristaltic move- ments. The systemic effects of aconite follow within a half -hour after its administration. The number and force of the heart-beats are reduced, and the arterial tension is lowered. The action of the skin is increased, and a more abundant urinary discharge takes place. If the quantity has been a full medicinal dose, some muscular weakness, tingling in the tongue, lips, and extremities, are also experienced. The whole du- ration of the effect is about three hours. When a lethal dose is swal- lowed, the symptoms begin in from five minutes to a half -hour. In a medical student, who swallowed by mistake a teaspoonf ul of the tinc- ture of the root, the symptoms began after he had reached the college, having walked from his quarters — the time being about twenty min- utes. He experienced an overpowering sense of fatigue in the lower extremities, and he felt, also, great muscular weakness. His eyesight became dim, the globes rather prominent, the pupils dilated. He expe- rienced great dyspnoea, and his respirations were shallow and labored. The pulse was at first slow and small, and at last became imperceptible. The surface of the body, the tongue, and breath, were cold. The skin was covered with a profuse sweat. He was restless, anxious, and sighed frequently ; but he had no stupor or convulsions. There were also decided numbness and tingling in the extremities, and in the tongue and lips. Tactile impressions were very faint, and the sense of pain was greatly reduced, so that he seemed almost unconscious of irritants. His temperature fell 2° Fahr. Under the use of heat, bran- ACONITE. 599 dy, and ammonia, he revived in the course of six hours, and, on the following day, although weak, there were no indications of the effects of the poison. Aconite affects the sensory nerves before the motor. It paralyzes first the end-organs, next the nerve-trunks, and finally the centers of sensation in the cord. Aconite also impairs the reflex function of the spinal cord ; but this effect is, doubtless, secondary to the sensory paralysis. The power of voluntary movement continues after the cessa- tion of the reflex functions ; but it is finally lost. The arrest of motil- ity is due to the action of the poison on the motor centers of the cord, and subsequently on the nerve-trunks. Aconite, applied directly to the heart, lessens the number and force of its beats, and finally arrests its action in the diastole. The cardiac muscle, after the cessation of its movements, does not respond to gal- vanic excitation. Aconite lowers the arterial pressure, as well as less- ens the force of the heart-beat. From these facts it may be concluded that it is a direct cardiac poison, affecting its ganglia and muscle, and also a sedative to the vasor-motor nervous system. It is also a respira- tory poison, in virtue of its paralyzing action on the muscles of respi- ration ; but the action of the heart ceases before the respiratory move- ments. Aconite increases elimination by the skin and kidneys. With in- creased discharge of water, there takes place, also, increased excretion of solids. Therapy. — The monopoly by homoeopathic practitioners of the use of aconite has aroused a prejudice against it, which has discouraged its employment. Aconite is, however, an antagonist to the fever-pro- cess ; it is not applicable in accordance with the so-called law of simi- lars. It is used by these quacks because it is a powerful agent which will produce manifest effects in small doses, that may easily be dis- guised. The author can quite agree with Dr. Ringer in the statement that aconite is a very valuable medicine, in the class of cases to which it is adapted. It lessens the pulse-rate, lowers arterial tension, diminishes abnormal heat ; it therefore antagonizes that condition of the organism known as fever. As it also slows the respiratory movements, and thus lessens the amount of work done by the breathing apparatus, it is espe- cially indicated in inflammatory states of the respiratory organs. As it diminishes the sensibility of the sensory nerves, it is useful in certain forms of neuralgice. As it induces muscular weakness and lowers the activity of the reflex functions, it is indicated in morbid states charac- terized by an excess of motor activity. Tonsillitis, acute pharyngitis, ulceration of tonsils, when accom- panied by fever and elevated arterial tension, are greatly relieved by the use of the tincture of aconite. From a half -drop to one drop every 600 MOTOR DEPRESSANTS. half -hour, until an impression is made on the fever-movement, and then every hour or two, is the best mode of administration. In acute catarrh (nasal and faucial), acute otitis, and in acute catarrhal bronchitis, the best results may be obtained by the use of aconite, as above described. The author's observations entitle him to speak with confidence of the good effects of this remedy in catarrhal and fibrinous pneumonia. It is more especially serviceable before exudations have taken place, but is not without utility at any stage, provided the inflammatory process continues. It not only abates the symptoms, but it favors the removal of the products of inflammation, by increasing elimination through the skin and kidneys. The use of aconite is not incompatible with the employment of other measures which may be needed ; but, generally, in fibrinous pneumonia, aconite is sufficient up to the period of crisis. The author has witnessed excellent results from the use of aconite in small doses frequently repeated (one drop every hour) in lowering the temperature of phthisis, especially when new districts of pulmonary tissue are invaded by pneumonitis. For the treatment of acute pleuri- tis, previous to the stage of effusion, no remedies are more effective than aconite and opium. 1} Tinct. aconiti rad., 3 ij ; tinct. opii deodor., 3 vj. M. Sig. : Eight drops in water every hour or two. If the pain is severe, a larger dose of opium should be administered, when the effect can be maintained by the quantity directed in the above prescription. Over action of the heart, icith hypertrophy and without valvular lesion, especially if there be present a condition of plethora, is bene- fited by a quantity of aconite sufficiently large to moderate the cardiac movements. Aconite is contraindicated in inflammatory states of the gastroin- testinal mucous membrane. It is very serviceable in acute congestion of the liver and hepatitis: it diminishes the fever, and, by causing free transpiration, lessens the pungent heat of the skin. Peritonitis is best treated by a combination of aconite and opium, as described above for pleuritis. Generally, the opium needs to be given in somewhat larger quantity in peritonitis than in pleuritis. In pelvic peritonitis, puer- peral metritis, and peritonitis, aconite is indicated, and is of unques- tionable utility, provided there be present a condition of sthenic reac- tion. A condition of adynamia, on the other hand, always contraindi- cates the use of aconite. The simple fevers of childhood, febricula, ephemeral fever, arising from various causes, as cold, fatigue, excitement, etc., are best treated by small and repeated doses of aconite. The remedy induces sweat- ing, and then the fever-movement subsides. The hot stage of intermit- tents and remittent fever, if any febrifuge is required, maybe relieved of its intensity by frequently-repeated doses of aconite. The continued fevers are not benefited by this remedy unless a condition of hyperpy* ACONITE. 601 rexia is threatened, when aconite may be used in connection with other antipyretic remedies. Aconite possesses the highest value in the eruptive fevers, especially in scarlet fever. There are two conditions of this disease especially requiring the use of aconite — the eruptive stage, and the period of des- quamation, if, as is usual, a marked rise of temperature takes place at this period of the disease. Several important purposes are subserved by the use of this remedy : it lowers the fever-heat, favors the action of the skin and kidneys, and checks the nasal, faucial, and aural in- flammations, which constitute such troublesome complications and sequelae. The particular utility of aconite in measles consists in its power to arrest the catarrhal pneumonia, one of the most serious com- plications of this disease. We have no remedy more useful in erysipe- las — idiopathic, so called, and not arising from trauma ; but, on the other band, Ringer describes an apparently erysipelatous inflammation following vaccination, which is quickly cured by aconite. According to the author's observations, it is facial erysipelas which is most de- cidedly benefited, and cases characterized by sthenic reaction. When there is a state of adynamia present, the eruption being dusky and the cutaneous circulation languid, belladonna is preferable to aconite. When, in acute rheumatism, there are much heat and a dry skin, instead of the usual sweating, aconite is very serviceable. It affords very con- siderable relief in muscular rheumatism when there is much fever. In acute inflammation of the cerebral and spinal meninges, and in cerebrospinal meningitis before effusion has taken place, aconite is as serviceable as in other acute inflammations. It is generally advisable to combine opium with it, especially in cerebro-spinal meningitis. In acute maniacal delirium, and in mental disorders generally, when there is much motor activity, with vascular excitement and increased ar- terial tension, aconite is useful, but is not so effective as gelsemium. Aconite renders important service in the active form of acute cerebral congestion. Neuralgia, when accompanied by arterial excitement and muscular spasm, is relieved by aconite ; but generally the neuralgias are much more successfully treated by hypodermatic injections and galvanism. It is asserted by Ringer, and also by Phillips, that sudden suppres- sion of the catamenial flow, caused by cold, can be relieved by aconite, in drop-doses of the tincture every half -hour or hour. The author can assert that this remedy has a high degree of utility in congestive dys- menorrhoea, occurring in plethoric subjects. These are cases, also, in which gelsemium is so undoubtedly beneficial. Aconitine in Trigeminal Neuralgia. — Remarkable results have late- ly been obtained by the use of Duquesnel's aconitine in this malady. The following formula is proposed by the New York Therapeutical Society : 1$, Aconitinse (Duquesnel's), gr. -^ ; glycerini, alcohol., aa 3 j ; 602 MOTOR DEPRESSANTS. aquae menthae pip., ad 1 ij. M. Dose, a teaspoonful. The dose is sometimes very slowly and cautiously increased to -J-. Although it does not succeed in all cases of tic-douloureux for obvious reasons, it relieves remarkably in others (Seguin). JVapelline. — Duquesnel has lately rediscovered (?) a principle to which he has applied the name napelline. Its physiological actions have been studied by Laborde. He finds it weaker than aconitine, and was able to administer without ill results from a half (^) grain to three fifths (f) of a grain. It possesses valuable hypnotic properties, and it is proposed to use it as a substitute for opium and chloral. On trial it proved to be an effective remedy in neuralgia, and as a sleep- producing agent in cases of wakefulness, mental excitement, and allied conditions. If further investigations confirm those observations, it will be a valuable addition to the materia medica. Authorities referred to : Achscharumow, Dr. Archiv fur Anat. und Physiologie, 1866, p. 255.

VERATRUM VIRIDE. 603 Composition. — Veratrum album, veratrum viride, and veratrum sabadillse, correspond closely in chemical composition, and the first two in botanical characteristics. Sabadilla is only used as the source of the alkaloid veratrine. The alkaloids of veratrum album arejervi?ie and veratralbine (Mitchell). Veratrum viride contains two alkaloids also— jervme and veratroidine. The alkaloid jervine is found in both plants, is the same in chemical action and in physiological effects, and may, therefore, be considered identical. There are very close affinities between the veratralbine of Mitchell and the veratroidine first discov- ered by Bullock, but they are not the same ; they differ as respects their chemical relations, and also in physiological properties, veratral- bine being much more powerful than jervine and veratroidine. Vera- trum album and veratrum viride contain abundance of soft resin, which, when pure, is nearly, if not quite, inert. As the alkaloid jer- vine is with difficulty separated from the resin, it is probable that the physiological activity, ascribed to the resin by some observers, is really due to the presence of the alkaloid. Antagonists and Incompatibles. — The effects of veratrum viride on the heart are counterbalanced by alcoholic stimulants, opium, and ammonia. When dangerous symptoms are produced, the recumbent position should be enforced, alcoholic stimulants should be adminis- tered by the stomach and rectum, and dry heat should be applied to the body. Ammonia may also be given by the stomach or by intra- venous injection, and, if nausea and vomiting persist, morphine may be administered subcutaneously. The tincture of opium, in stimulant doses, may be prescribed with the alcoholic stimulants. Synergists. — The vaso-motor depressants — tobacco, lobelia, aco- nite, etc. — are synergistic. Blood-letting, haemorrhage, purgatives, and all agencies which diminish vital power, increase the effects of veratrum. Physiological Effects. — In the remarks which follow, veratrum viride only is referred to. Applied to the skin, veratrum viride excites redness and heat, and, to the Schneiderian mucous membrane, it causes violent sneezing. It is a prompt and efficient emetic, but its operation is accompanied with intense nausea and depression, and the vomiting is often violent and persistent. The contents of the stomach are at first evacuated, and afterward of the gall-bladder, so that it has been supposed to possess the power to increase the secretion of bile. It does not generally purge, but occasionally profuse watery evacuations have been produced by it, and rarely severe hypercatharsis. Its alkaloids enter the blood with facility. The power which veratrum viride has to affect the car- diac movements and the vascular tonus is its most characteristic prop- erty. It lowers, in a remarkable manner, the number and force of the cardiac pulsations. The pulse may be reduced to fifty, forty, or even 604 MOTOR DEPRESSANTS. thirty-five per minute, and its force correspondingly diminished. Ac- cording to Linon, the arterial tension is raised, as shown by the sphyg- mograph. By very careful administration, this reduction in the pulse- rate may sometimes be accomplished without inducing nausea and vomiting, but usually vomiting can not be prevented when the remedy is pushed to this extent. When the pulse is reduced very decidedly, the patient being in the recumbent posture, a change to the erect posi- tion at once alters its character, and it becomes extremely rapid, thready, and feeble. Yery great depression of the powers of life is produced by large doses. The action of the heart becomes exceedingly weak, the pulse almost indistinguishable, the vomiting and retching extreme, the sur- face of the body cold and covered with a cold sweat, the temperature reduced. There are also produced faintness, dimness of sight, dilata- tion of the pupils, giddiness, great muscular weakness, shallow and slow respiration ; sometimes somnolence, coma, and insensibility, with stertorous breathing. Notwithstanding the very formidable symp- toms produced by large doses, fatal results have been extremely rare. An ounce of the tincture has been swallowed without causing death (Norwood). The prompt emesis which it produces is probably the explanation of its lethal inactivity ; for, in the act of vomiting, the medicine is ejected with the first matter from the stomach. Suspen- sion of the medicine and free stimulation quickly remove the most alarming symptoms of depression. The experimental investigations into the actions of jervine and veratroidine, made by Wood, Peugnet, and others, have shown that the physiological actions of veratrum viride are the sum of the ac- tions of the alkaloids. The nauseating and emetic qualities of the drug are due, chiefly, to veratroidine, and to a slight extent to the resin. Both alkaloids depress the functions of the spinal cord, and destroy its reflex activity ; but they do not impair the excitability of the nerves, nor the contractility of muscles. Veratroidine, according to Wood, first stimulates the inhibitory cardiac nerves to an extraor- dinary extent, and afterward paralyzes them ; but the evidence which he adduces in favor of the singular statements on this point are far from satisfactory. Both alkaloids lower the blood-pressure, by dimi- nution of vaso-motor tonus, and paralyze the cardiac muscle, and probably also its contained ganglia. They cause death by asphyxia — by paralysis of the muscles of respiration. The cerebral effects which have been noted in man, and the convulsions in animals, are doubtless due to the accumulation of carbonic acid in the blood. Theeapy. — The best preparation for administration is the tincture. As the therapeutic properties of veratrum viride depend, chiefly, on the jervine, an attempt may be made in the future to supply this alka- loid in sufficient quantity for administration ; but, at present, the pro- VERATRUM VIRIDE. 605 cesses involved in its preparation are too intricate and expensive. As the effect of veratrum viride quickly reaches its maximum, if it be de- sired to maintain the pulse-rate at a constant level, the doses must not be at a longer interval than two hours. The effect must be main- tained by increasing doses, if necessary, and the recumbent posture must be rigidly enforced. The emetic property of veratrum viride is never applied in prac- tice ; too much depression is produced by it. The chief use of this agent is to depress the action of the heart and to lower the vaso-motor tonus. In simple hypertrophy of the heart, without valvular lesion, it diminishes the overaction and thus gives relief to the most distress- ing symptom. The irritable heart, so frequently found associated with and dependent on the excessive use of tobacco, on mental excite- ment and irascibility of disposition, and on overstrain, is relieved by this remedy, provided no valvular lesions coexist. The hypertrophy of the cardiac muscle, and the abnormal arterial tension, which ac- company the chronic form of albuminuria, are alleviated by veratrum viride. Moderate doses of the tincture (five drops ter die) usually suffice in these cases. When there are valvular lesions, and when the cardiac muscle is enfeebled from any cause, this agent is inad- missible. Excellent results are sometimes obtained in aneurism by the use of veratrum viride. In the various surgical expedients for the cure of aneurism (forced flexion, compression, ligation), this remedy, used to depress the circulation, renders an important service, by lessening the force with which the blood is propelled, and the number of the cardiac contractions. In this way, coagulation of the blood in the aneurismal sac is greatly favored. In the case of large internal aneurisms — of the innominata, aorta, etc. — veratrum viride is a powerful adjunct to rest and other means of treatment. Some precautions are necessary, however, in the administration of this remedy. As the utmost slow- ing of the circulation consistent with safety may be required, a suffi- cient quantity of the tincture must be administered to accomplish this object, and the effect produced is the only measure of the amount to be given. The result must be accomplished, if possible, without caus- ing vomiting. The patient should, therefore, remain absolutely in the recumbent posture, and a little opium should be prescribed with the veratrum viride. Active haemorrhage, occurring in the plethoric, is sometimes stopped by full medicinal doses of this drug. There can be no doubt that veratrum viride renders an important service in acute parenchymatous congestion — of the brain, lungs, liver, and other organs. Its utility ceases when exudations have taken place : its action is confined to the influence which it has in diminish- ing the blood-supply to the affected organs. The changes produced by inflammation are in no wise affected by veratrum viride. Much 606 MOTOR DEPRESSANTS. that is extravagant has been written in regard to its curative influence in pneumonia, but we need not be surprised at this, when we reflect that our knowledge of the natural history of this disease is only of recent origin. Those who knew nothing of the period of crisis of pneumonia naturally attributed the defervescence of temperature to the effect of the remedy. It is not to be denied that in the very in- cipiency of pneumonia, before fibrinous exudation has taken place, veratrum viride, by lessening the amount of blood circulating in the lungs, may render an important service, but when hepatization occurs its good effects cease. The same observations are true of other pa- renchymatous inflammations, and equally so of serous inflammations. Veratrum viride has been much extolled as a remedy for reducing the pulse-rate and the temperature in typhoid and other fevers (Nor- wood). It is true, these effects may be procured by it, but that any influence is exerted in this way, over the course and duration of a fever, seems highly improbable. The chief dangers in fever being the occurrence of cerebral or cardiac paralysis due to the persistent eleva- tion of the temperature, it is unwise to use a powerful cardiac depres- sant, although it has the power to lower the temperature somewhat. There is, however, a condition of things arising in the course of fevers — viz., delirium ferox — in which, when dependent on arterial excite- ment, much good may be accomplished by the use of veratrum viride. The excitement of acute mania, of maniacal delirium, and other forms of mental disorder in which a condition of cerebral hyperemia may be supposed to exist, is successfully combated by veratrum viride. In a private communication, Dr. Sullivan, of San Francisco, informs me that this agent ( 3 ss of the fluid extract every fifteen minutes until nausea or vomiting ensues) is "invaluable in puerperal convulsions" Barker, in his " Puerperal Diseases," had already called attention to its utility, and Boyd confirms the previous observations. It well de- serves trial in this malady and in analogous states. Veratrine is used only externally, and for the relief of neuralgia, headache, myalgia, etc. The official unguentum veratrim is the form in which it is employed — a small quantity being rubbed in over the seat of pain.

The tincture is the form usually employed in medical practice, the dose of which varies from one minim to twenty minims. Composition. — The peculiar powers of the plant depend on the presence in it of an alkaloid — anemonme i a camphor. Anemonine crystallizes in prisms — the regular rhombic system — and is hardly at all soluble in cold water and in alcohol (Husemann). Pulsatilla also contains a peculiar acid — anemonic acid. Antagonists and Ixcompatibles. — The caustic alkalies, tannic acid, and the metallic salts generally, are chemically incompatible. From the physiological standpoint, pulsatilla is antagonized by the alcohols, by opium, digitalis, etc. Stxeegists. — The effects of pulsatilla are promoted by the para- lyzers, especially by the other members of the same family — notably, by aconite, veratrum viride, etc. Physiological Actions. — The local effects of pulsatilla (the fresh plant) are those of an irritant ; and, after prolonged contact, even caustic effects are produced. Applied to the tongue, it gives rise to tingling, burning, followed by numbness — effects very similar to those caused by aconite. On the intestinal mucous membrane it has very pronounced irritating effects. The active principles diffuse into the blood with facility. Depression of the heart's action, lowering of the arterial tension, and declination of temperature, are caused by pulsa- tilla. It is a paralyzer of motility and sensibility, but, as respects the motor functions, it is not known whether it impairs the contractility of muscle or the irritability of nerve ; and, as respects sensation, it has not yet been determined whether the lessened sensibility is due to an influence which this remedy has on the spinal cord, on the nerve- trunks, or on the peripheral expansion — end-organs of the sensory sys- tem. Dilated pupils, hebetude of mind, stupor, coma, and convulsions, are cerebral symptoms which occur after a lethal dose has been ad- ministered. These cerebral effects may be due to a primary action of pulsatilla on the brain, or to the carbonic-acid poisoning and the anae- mia. When the action of the heart and the respiration are very feeble, 608 MOTOR DEPRESSANTS. carbonic acid accumulates in the blood, and an extreme degree of cere- bral anaemia ensues. Coma, convulsions, and insensibility, are natural effects of these causes. Nothing is positively known as to the time and mode of elimination of anemonine, but it is probable that excre- tion takes place by the kidneys. The production of any given physiological effect will, of course, depend on the genuineness of the drug. The active principles are volatile, and often disappear in the process of desiccation. Therapy. — Owing to the irritating action of pulsatilla, it is not suited to the treatment of gastro-intestinal disorders, especially when a state of inflammation exists. Notwithstanding this local irritant effect, homoeopathists employ it for the relief of dyspepsia and the accompanying mental symptoms ; but, in coming to conclusions as to its curative value, they calmly ignore the natural history of these maladies. Pulsatilla is adapted to the treatment of acute inflammation of the nasal, faucial, laryngeal, and bronchial mucous membrane — acute catarrh. It is not proper in those cases when accompanied by gastro- intestinal disturbance. It is clearly useful in acute inflammation of the cerebral and spinal meninges. It is used by the homoeopathists in the treatment of catarrhal oph- thalmia, by internal and local applications ; and they hold that it is very efficacious in certain diseases of the uterus, on which organ they suppose it to have a special or specific action. Sudden arrest of the menstrual floio, whether caused by moral emotion or by cold, may be relieved, and the effects prevented, by pulsatilla. As aconite is very useful under the same circumstances, it may be assumed that good results may be had by the administration of pulsatilla. Authorities referred to : Gtjbler, Prof. A.

Composition. — An alkaloid with basic properties has been isolated (Rademaker), but its chemical relations have not been fully made out. The plant contains also a volatile oil, and a resin, to which its physio- logical activity is doubtless in part due. Antagonists and Incompatibles. — Water precipitates the oleo- resin. The mineral salts and caustic alkalies are chemically incom- ' GRINDELIA. 609 patible. Opium, the cerebral stimulants, alcohol, strychnine, picrotoxin, etc., are opposed as respects the physiological actions. Synergists. — All motor depressants increase the actions of grin- delia. Physiological Actions. — The taste of grindelia is rather pungent, even acrid, and in the stomach it excites a sensation of warmth. The local stimulant effect is such that it promotes the appetite and diges- tion ; but, if too long continued, or in too great quantity, it excites gastric uneasiness. Grindelia slows, somewhat, the heart and respira- tory movements. When administered in sufficient quantity, decided cerebral effects are produced. It dilates the pupil and induces sleep. During this condition of hypnotism, the general cutaneous sensibility is much reduced, and reflex movements become sluggish. Motility is also affected, the paresis beginning in the hind extremities. Its toxic powers are by no means great, two drachms of the fluid extract be- ing required to induce sleep in small rabbits. It affects other warm- blooded animals, and also frogs, in the same way. When death ensues, it is from paralysis of the muscles of respiration. Elimina- tion takes place by the pulmonary mucous membrane, and chiefly by the kidneys. Therapy. — The most important uses of grindelia, thus far devel- oped, are in the treatment of the respiratory neuroses. Its utility in the treatment of asthma, especially the so-called spasmodic asthma, is certainly great ; few cases fail to be relieved at once. Besides the stomach administration, it may be given in the form of fumes, accord- ing to the following plan : The plant is steeped in a saturated solu- tion of nitre, dried, when it may be ignited on an ordinary tin plate, the patient inhaling the fumes as they arise, or the fumes in the air of a small, closed apartment. This preparation may also be rolled into cigarettes, and smoked with or without the addition of tobacco, stra- monium, lobelia, etc. The fluid extract of grindelia may be incorpo- rated with other asthmatic remedies, in an extemporaneous prescrip- tion. For example : ^ Ext. grindeliae fluid., 3 ss ; ext. lobelia? fl., 3 ij ; ext. belladonna? fl., 3 j ; potassii iodidi, 3 iij ; glycerini, f iij. M. Sig. : A tablespoonful, as necessary. Cough by imitation and habit, whooping-cough, and the spasmodic difficulty of breathing which accompanies various pulmonary and car- diac diseases, hay-asthma, etc., are helped by grindelia. It is also an effective remedy for bronchitis, after the subsidence of acute symp- toms ; for chronic bronchitis and bronchorrhoea, and for the bronchitis of emphysema. Besides the above diseases for which grindelia has been used with success, it will prove advantageous in chronic pyelitis, chronic cystitis, etc. In these diseases local application of the oleo-resin takes place all along the urinary tract. 39 610 MOTOR DEPRESSANTS.

Composition. — Claussen has obtained a neutral principle, which he has named phytolaccin, but this should not be confounded with an impure resin called by the eclectics "phytolaccin." Claussen's phyto- laccin occurs in silky, shining crystals, soluble in alcohol and ether, but not in water. A peculiar acid, phytolaccic acid, has also been found in the berries by Terail. It is uncrystallizable, but soluble in water and in alcohol. Antagonists and Incompatibles. — Alcohol, ether, opium, digitalis, etc., oppose the action of phytolacca. Synergists. — All depressing agents, the paralyzers, and emetics, contribute to the effects of phytolacca. Physiological Actions. — Poke is nauseant and emetic, and these effects occur, whatever may be the mode of administration. The emesis does not occur at once ; there is a slowly-accumulating anguish ; vomit- ing does not result for an hour, and the vomiting is accompanied with great depression. Rutherford has shown that the eclectic preparation phytolaccin has decided cholagogue property — ranking, indeed, among the most effective of the agents influencing the flow of bile. Phytolacca lowers the rate of cardiac movement and the respiration, but does not alter the rhythm. It is a paralyzer, the loss of power occurring first in the hind extremities. The impairment of motility is not due to an action of this agent on the motor nerve or on the muscle — for the irritability of the nerve and the contractility of muscle remain unaffected when a lethal dose of phytolacca has been given. The action is on the spinal cord, chiefly on the medulla. In rabbits, violent trem- bling occurs, and convulsions, partly tonic, partly clonic, are produced. Death ensues from paralysis of respiration ; for in frogs, when all signs of life have ceased, the heart is found to be in action, on opening the chest. In cases of accidental poisoning, convulsions of a tetanic char- acter have been observed. Elimination takes place chiefly by the kidneys. Therapy. — Poke has been proposed as an emetic, but the slowness of the action, and the great depression of the powers of life which it AILANTHUS. 611 causes, have prevented, and will ever prevent, its employment for this purpose. Alterative powers have been ascribed to it, and cases supposed to be malignant have been cured ; but these results were probably in- stances of the post rather than the propter hoc. Ulcers, cutaneous dis- eases, and ophthalmia, are maladies which have been reported cured. Fenner reported a case of granular conjunctivitis cured by it, and in the same issue of the journal there is an editorial note, affirming the remarkable powers of the remedy in this disease. If it really does cure this disease when given by the stomach, poke is a remedy of ex- traordinary value. The evidence is strong that phytolacca does pos- sess considerable power to promote the healing of varicose and other ulcers of the leg (Tidd). A soft extract is spread on muslin, and kept applied to the surface of the ulcer. Obstinate eczema has been cured in the same way. The pain and inflammation of burns may be as- suaged by the same application, and the healing greatly facilitated. How far the effect is merely mechanical does not appear. It has long been known that phytolacca is a serviceable remedy in chronic rheumatism. But the therapeutical application of this remedy most deserving of consideration is the treatment of inflamed breasts. There seems to be no reason to doubt that phytolacca possesses the remarkable property of arresting an inflammation of the mamma, and preventing suppuration. For this purpose the fluid extract may be given internally, and the solid extract spread on a cloth and kept applied to the breast which is the seat of the inflammation. The pos- session of this property to prevent suppuration in the breast implies the existence of the same property in threatened suppuration in other glandular organs. As the fact is entirely empirical, and rests on no physiological action of the drug, it can only be determined by further trials whether it will check suppuration elsewhere.

Composition. — The most important constituent is the oleo-resin. It contains, also, a volatile oil, which is extremely diffusible and pow- erful, and a bitter principle. Actions and Uses. — The taste is bitter and somewhat acrid. It is strongly nauseant, and the nausea is accompanied with weakness, ver- tigo, and cold sweating. It possesses decided purgative property, the 612 MOTOR DEPRESSANTS. stools being large and watery. It has considerable power as a vermi- fuge, and is effective when employed against taenia. The action of the heart is at first increased, but is subsequently slowed, the pulse becom- ing small and weak. Respiration is similarly affected, and death en- sues in animals by paralysis of the muscles of respiration. On the brain and nervous system ailanthus acts as a paralyzer, the loss of power beginning in the hind extremities. The paralyzing ac- tion seems to depend on the volatile oil, while the purgative and an- thelmintic effects are possessed by the oleo-resin. Therapy. — The most important application of ailanthus is in the treatment of tape-worm. For this purpose the oleo-resin, or, better, a decoction of the fresh bark ( 3 j — 5 iv), may be used. The oleo-resin has the advantage in being a permanent preparation, whereas the bark loses its strength in the process of drying. Muscarine. — The alkaloid of Amanita muscaria, the fly-fungus. Properties. — Muscarine is an alkaloid with strong basic properties, and combines with acids to form salts. It has the consistence of sirup, is without odor, free from taste, and is readily soluble in water and in alcohol, but is insoluble in ether and in chloroform. Besides being obtained from the fungus, it has been constructed synthetically, the product having the same actions, it is alleged ; but this statement seems doubtful, especially in view of the rather negative results reached by Ringer, with a specimen furnished by Merck, of Darmstadt. As muscarine is but slightly irritating to the tissues, it may be used subcutaneously. The dose ranges from one eighth of a grain to two grains. According to Ringer, one third of a grain is the mini- mum quantity to produce symptoms in men, administered hypoder- matically, but in this statement he referred to Merck's alkaloid pre- pared synthetically. Antagonists. — The actions of muscarine are antagonized by atro- pine (Schmiedeberg and Koppe), by digitaline (Bohin), and by eserine (Prevost). By atropine it is antagonized at all points. When the heart is arrested by muscarine, it possesses the capability of again re- newing its action under the influence of a large number of agents, but atropine possesses this property in the highest degree (Alison). Mus- carine .arrests the heart in diastole by stimulating the intracardiac in- hibition apparatus — atropine paralyzes this apparatus (Prevost) ; mus- carine causes intense dyspnoea by inducing strong contraction of the pulmonary arteries — atropine relaxes this spasm, unloads the right cavi- ties of the heart, and respiration is resumed ; muscarine lowers, atro- pine raises the blood-pressure ; muscarine tetanizes the muscular layer of the intestine — atropine induces a paresis of the same ; muscarine in- creases the secretions of liver, pancreas, and intestinal mucous mem- brane — atropine arrests these secretions ; muscarine stops the renal MUSCARINE. 613 secretion — atropine restores it ; muscarine causes sweating, salivation, and lachrymation — atropine dries them all ; muscarine contracts the pupil — atropine dilates the pupil. For the quantity producing a given physiological effect, the power of the two agents is very unequal, atropine being much stronger. An atropinized eye dilated to a cer- tain point will not be contracted by the quantity of muscarine suffi- cient when unopposed to induce a marked degree of myosis ; but a much larger quantity may overcome the atropine. The same fact is true throughout the whole range of their antagonistic action. In frogs poisoned by digitaline, the cardiac movements recommence and are maintained for hours by the application of a solution of mus- carine. The same fact is true of tobacco and physostigma : the heart arrested by these agents recommences movements when muscarine is applied, and vice versa. Synergists. — The motor depressants synergize some of the actions of muscarine. A close correspondence exists between pilocarpine and muscarine. They both cause nausea, diarrhoea ; muscarine at first quickens then slows, and pilocarpine quickens the pulse ; they both flush the face and produce free perspiration and salivation ; they both cause frontal headache ; both contract the pupil ; and both diminish the urinary secretion. They differ in some respects, but chiefly in the extent of their action, or quantitatively. Pilocarpine causes more perspiration and salivation ; muscarine produces decidedly more active intestinal movements. Pilocarpine diminishes the urinary secretion, but muscarine may arrest it entirely. Pilocarpine slightly contracts the pupil ; muscarine contracts the pupil more decidedly, but when applied to the eye directly, dilates the pupil. Pilocarpine always quickens the pulse, muscarine slows the pulse. Physiological Actions. — The salivary secretion in a large pro- portion of subjects is much increased. A feeling of constriction of the neck, nausea, and vomiting, and more or less abdominal pain, are produced by it, whether administered by the stomach or subcutane- ously (Brunton). The pancreatic and biliary secretions are notably in- creased after the injection of some milligrammes into a vein (Prevost). This increase of these secretions took place as well between as during digestion. The intestinal mucus is also greater in quantity than nor- mal, and it may be streaked with blood (Schiff). The intestines are thrown into active contractions, tetanized, rather than merely stimu- lated into more frequent vermicular movements. Under ordinary medicinal doses in man, the bowels are relaxed and the character of the evacuations altered, doubtless, because of the much greater quan- tity of the biliary and pancreatic secretions poured out. The increased movement of the intestines is accompanied by considerable colic-like pain. Muscarine enters the blood promptly, whether introduced through 614 MOTOR DEPRESSANTS. the stomach or subcutaneously. It is a cardiac poison. A very mi- nute quantity — a mere trace — applied to the frog's heart, arrests its movements. As Schmiedeberg and Koppe first demonstrated, it ar- rests the heart in the diastole, and does not impair the irritability of the heart-muscle, for, on irritation of the heart by mechanical, chemi- cal, or electrical means, it again contracts. If the dose is short of lethal, the heart is merely slowed, the number of pulsations being- reduced ten, twenty, or even forty beats per minute. Section of the vagi does not affect this result. The action is due to stimulation of the intracardiac inhibitory apparatus. By Alison it is referred to over- excitation of the cardiac terminals of the vagus, and coincident dimi- nution in the activity of the sympathetic fibers. When the effects of muscarine are manifested by a diminution of the pulse-rate, the blood- pressure begins to decline. At first the vessels contract, but this is soon succeeded by dilatation (Bogosslowsky). With the slowing of the heart and dilatation of the vessels, the blood accumulates in the periphery, and the blood-pressure is consequently reduced one half. Disturbances of respiration occur with the other defined symptoms. The breathing grows more labored with the increasing effects of the agent, and presently an intense dyspnoea supervenes (Schmiedeberg). The mechanism of the labored respiration is obvious enough. Such a strong contraction of the pulmonary vessels ensues as to greatly di- minish the quantity of blood circulating in the lungs, with the result of over-distention of the right cavities of the heart. Hence it follows that the state of the blood is impaired by the lack of oxygen and the retention of carbonic acid, and to these factors must be attributed in part the cyanosis and asphyxia. These modifications of the respiration occur after preliminary section of the vagi. The almost arrested oxy- genation of the blood, the languid circulation, and the profuse perspi- ration, are the factors which cause a lowering of the temperature. By Schmiedeberg and Koppe there are recognized three conditions of the body-heat : 1. A slight elevation, which is by no means constant, and very transient, coming on in about two hours after the dose — a small one — has been taken ; 2. A depression of one or two degrees, suc- ceeded presently by the normal temperature, produced by a full medi- cinal dose ; and, 3. A very pronounced lowering of the temperature from a fatal dose. By the internal administration of muscarine the pupil contracts, and, singularly enough, by direct application, dilates. There are other ex- amples of this paradox. Vision is disturbed by alteration of the ac- commodation apparatus by spasm. The myosis depends on stimulation of the circular fibers of the iris or of the third nerve, and not on paral- ysis of the radiating fibers, or of the sympathetic filaments. Muscarine produces abundant perspiration, and, indeed, stimulates this function only less powerfully than pilocarpine. In most cases the MUSCARINE. 615 saliva is correspondingly increased. The two functions do not always act together with the maximum energy, and one may be powerfully affected, while the other is quiescent. Lachrymation is nearly con- stant, and the nasal mucus is more abundant than in the normal state. Thus, while all other secretions and excretions are increased by mus- carine, it is remarkable that the urine should be decidedly lessened in amount, even suppressed. In eight experiments made with great care, Prevost found that the injection of muscarine into a vein diminished the urinary secretion, and, indeed, almost stopped it when the dose was large. The elimination of muscarine takes place by the kidneys. The best evidence that it is excreted unchanged is the physiological action of the urine. The urinary secretion of an animal poisoned by muscarine will poison another animal to whom it is administered, and its powers are transmitted with little diminution through several. Therapy. — The applications of muscarine to the treatment of dis- ease are yet in their infancy. The physiological effects indicate the direction of the remedial applications. As muscarine stimulates so powerfully the muscular fiber of the intestine, and the secretions of the pancreas, liver, and intestinal mucous membrane, it ought to be very serviceable in cases of constipation with torpor of the organs concerned in digestion. When constipation is due to paresis of the muscular layer of the bowel and to deficient secretion, this remedy will probably relieve it. In the treatment of intestinal torpor and de- ficient secretion, muscarine may be combined with other remedies, as atropine and strychnine, which act on the organs concerned, or with cathartics and cholagogues : $ Muscarine, gr. iv ; ext. belladonnge, ext. nucis vomicae, aa gr. iij ; euonymin, 3 ss. M. Ft. pil. no. xij. Sig. : One pill morning and evening. When the digestion of the starches and fats is imperfect, it is strongly indicated. In catarrh of the duodenum, and in catarrhal jaundice, it ought to be very efficient. In these maladies, the remedy should be administered frequently and in small doses : fy Muscarine, gr. j ; aquae, f j. M. Sig. : A tea- spoonful every three hours. It is probable, also, that it will prove useful in recent hemorrhoids due to congestion of the portal circulation. It promises well as a remedy for the removal of inflammatory effusions and exudations. It ought to afford prompt relief at the onset of a common cold, an acute bronchitis, hay-asthma, etc. As muscarine pro- duces strong contraction of the pulmonary capillaries, it ought to be useful in pulmonary haemorrhage, in incipient congestion of the lungs, etc. Under such circumstances the combination with digitalis ought to be especially effective, for, while digitalis will aid the curative ac- tion on the pulmonary vessels, it will, at the same time, antagonize the cardiac depression caused by muscarine. It is contraindicated in affections of the air-passages when secretion is in excess. For the night-sweats of phthisis fly-fungus has long been used, and a similar 616 MOTOR DEPRESSANTS. fungus is commended by Trousseau ; but it has not been as success- ful in the hands of Murrell as some other agents, although capable, sometimes, of very good results. Muscarine is of doubtful propriety, if not positively contraindicated, in renal affections characterized by deficiency in the excretion. On the other hand, it ought to be of sig- nal service in diabetes insipidus and in saccharine diabetes. It has been used successfully to arrest the secretion of milk.

Quebracho. — The bark of Aspidosperma quebracho, an apocynaceous tree of Chili. Preparations. — Tincture. — One part of quebracho to five parts of alcohol. Dose, TH, v — 3 j. Wine. — One part of quebracho, two parts of alcohol, and sixteen parts of white wine. Dose, a teaspoonf ul to a tablespoonful. A fluid extract, prepared according to the general directions of the Pharma- copoeia, will probably be found an eligible preparation. Composition. — Quebracho seems peculiarly rich in alkaloids, but it is doubtful whether any one represents in its entirety the physio- logical powers of the bark itself. The most important are aspido- spermine, discovered by Fraude in 1878, and quebrachine, separated by Hesse in the following year. Hesse describes several other active constituents or alkaloids, but the two just mentioned are the most important. Adulterations. — Soon after the first specimens were sent to Europe, the sudden demand which sprang up induced sophistication, and quebracho-wood and quebracho Colorado were substituted for the genuine. This substitution proved the less important, since these preparations acted in a similar manner, and were only weaker (Pen- zoldt). The early physiological investigations must, therefore, be in- terpreted by the light of this difference in the action of the several substances comprehended in the term quebracho. QUEBRACHO. 617 Physiological Actions. — Quebracho has the stomachal effects of the bitters in general : it promotes appetite and increases the diges- tive powers. The alkaloids diffuse promptly into the blood. The action of the heart is lowered ; the pulse in the normal state is less frequent ; at first, the tone of the artery is higher and the blood-press- ure is raised, but as the action is continued, especially from lethal doses in animals, the force of the circulation declines and the pressure falls. The respiration is also slowed, and the sense of need of air is less imperative. The hurry of circulation and of respiration, and the feeling of oppression induced by active exercise, are modified by quebracho. Picot-Berthold studied these actions on his own person. Ascertaining first the rate of increase of the respiratory movements and of the circulation induced by active exercise of a definite amount, he next determined the influence of the remedy on these functions when the same amount of exercise had been taken. While without quebra- cho his pulse and respiration rose respectively to 42 and 94, under the action of the medicament they were 30 and 80. Not only was the rate of movement lessened, but the accompanying distress for want of air was decidedly ameliorated. Guttmann, who has made an elaborate study of aspidospermine, finds that in both cold- and warm-blooded animals it is an active poison of the respiratory and circulatory apparatus. In cold-blooded animals the respiratory actions are most pronounced, and death is produced by the effect of the poison on the respiratory center. Slowing of the heart's action proceeds pari passu with the diminution of the respira- tory energy, and the cessation of the heart's movements is finally due to the impression of the poison on the intra-cardiac motor ganglia. In warm-blooded animals (cats) the influence of the poison on the heart is primary. The slowing of the pulse is not due to any effect which it has on the vagi, but to the paralyzing action which it exerts on the cardiac motor ganglia. With, the slowing of the heart the temperature declines, and, with the diminution of respiration, dyspnoea comes on. Then the accumulation of carbonic acid in the blood in- duces stupor, and in animals convulsions. The reflex function is low- ered in cold- but not in warm-blooded animals ; sensibility is unaf- fected in the latter, but motor paralysis finally occurs in both classes. Death is due to paralysis of the heart. Therapy. — The applications of quebracho in the treatment of dis- ease were originally empirical, but they are clearly deducible from its physiological actions. It has long been known as a fever-medicine and as a remedy for dyspnoea, in the province of Santiago, Chili, where it was first obtained by Dr. Schickendanz. It has been used as a stomachic tonic, like the bitters in general, but more especially like cinchona, to increase the appetite and digestion in atonic dys- pepsia. It is, however, chiefly important as a remedy for dyspnoea. 618 MOTOR DEPRESSANTS. Picot, Skoda, Krauth, Penzoldt, and many others, have used it in va- rious instances of difficult breathing, with remarkable palliation. In emphysema, spasmodic asthma, urwmic asthma, in spasmodic cough, chronic bronchitis, with asthmatic breathing, it has afforded very con- siderable relief. It has appeared to be much less useful, if not injuri- ous, in the dyspnoea from valvular disease of the heart, and has had no effect in the dyspnoea of old subjects due to atheroma of the vessels. Krauth, however, has used it with advantage in the dyspnoea due to hypertrophy of the heart and in the difficulty of breathing in a case of albuminuria consecutive to scarlatina. The relief to dyspnoea in all cases, Penzoldt thinks, is referable to the increased consumption of oxygen by the blood, but a more rational explanation would seem to be the action on the respiratory center, and the diminution in the sense of need of air. Having a paralyzing action on the cardiac motor ganglia, quebracho is not without danger in cases of weak heart. It must be considered a doubtful remedy when the motor apparatus of the heart is impaired — especially, if the accelerator nerves and their terminal ganglia are the parts damaged. On the other hand, when the lesions of the heart are merely valvular, it would appear to be safe ; but in the dyspnoea due to this cause it is much less useful (Laquer, Berger). Certain unpleas- ant results of its administration render prolonged use of quebracho very difficult. These are, according to Laquer, headache, dullness of the sense-organs, vertigo, salivation, and a strong repugnance to its taste. The preparation most used at present is the extract, and the usual dose for an adult is five grains. The alkaloid aspidospermine has been administered chiefly in the experimental way, but, although its actions correspond closely to those of the bark itself, it can hardly represent the drug in its entirety, seeing that there are several alkaloids con- tained in it. The salts of aspidospermine — the citrate, hydrochlorate, and sulphate — are freely soluble in water, while the alkaloid itself is not at all readily soluble in water, but is taken up freely by oils and fats — five to eight parts dissolving in one hundred parts of cod-liver oil by heat.

EMETICS. 619 REMEDIES USED TO CAUSE SOME EVACUATION FROM THE BODY.—EVACUANTS. EMETICS. Some of the agents in this group produce vomiting by virtue of a local action on the stomach, and do not affect this viscus when intro- duced elsewhere. These may be entitled Emetics by Local Action. There are others which cause emesis when they enter the blood at any point — Systemic Emetics. The first sub-group of emetics make an im- pression on the gastric nerves, and an action is at once instituted for their expulsion. The process consists in the transmission of the periph- eral irritation to the spinal center, the generation of a motor impulse, and the consequent action of the nervous and muscular apparatus concerned in the mechanism of vomiting. The systemic emetics pro- duce their effects through the intermediation of the blood, and the vom- iting is only one of the results of the disturbance introduced into the functions of the nervous system. EMETICS BY LOCAL ACTION. The most important of these are : Cupri sulphas, sulphate of copper. Zinci sulphas, sulphate of zinc. Hydrargyri sulphas flav a, yellow subsulphate of mercury. Alumen, alum. Sinapis, mustard. Scilla, squill. All of the members of this group have been discussed in other parts of this work, except mustard and squill, and the consideration of these will be more appropriate elsewhere. It is necessary, however, in this place to indicate the nature of the action, the cases to which they are adapted, and the mode of administration of the more important of the emetics belonging to this division. Cupri Sulphas. — This is a very prompt and efficient emetic. The action begins in a few minutes, and the medicine comes up with the vomited matters. Very little depression follows the emetic action. It is more especially adapted to the treatment of narcotic poisoning ', be- cause, the action being local, the obtunded state of the reflex centers interferes less with its operation than is the case with the systemic emetics ; and to phosphorus p>oisoning -, because of its antidotal power. It is also occasionally used in croup, to effect the dislodgment of the false membrane, but other mechanical emetics are preferable. Admlnisteation. — Dissolve twenty grains of the sulphate of copper in two ounces of distilled water, and give a tablespoonf ul every fifteen 620 EYACUANTS. minutes until vomiting occurs. When prompt action is required, as in narcotic poisoning, ten grains of the sulphate of copper may be given at a draught in an ounce or two of water. Its action should be assisted by the free use of diluents. Zinci Sulphas. — This agent acts in a manner similar to the corre- sponding copper-salt, but is less powerful. It has the advantage of be- ing less likely to induce gastro-enteritis than sulphate of copper, and is, therefore, usually preferred to the latter. It is administered in cases of narcotic poisoning, in croup, and to relieve the stomach of indi- gestible alimentary substatices. Administration. — In narcotic poisoning a scruple of the sulphate of zinc may be administered in water, and, if need be, repeated once. In croup, or for other purposes, as an emetic, it may be given as fol- lows : Dissolve a half-drachm in two ounces of water, and administer a tablespoonf ul every fifteen minutes until emesis is produced. The free use of diluents promotes the emetic action. Hydrargyri Sulphas Flava. — This is one of the most efficient mem- bers of this group. It is an active poison, but, as it is returned with the contents of the stomach, no danger attends its administration. It does not act so speedily as copper and zinc. It produces very little nausea, but, when the action begins, the effects are suddenly experi- enced, and are powerful, without leaving after-depression and sickness. It is not so well adapted to the treatment of narcotic poisoning as the copper and zinc sulphates, but it is the most desirable emetic in the treatment of croup. It was formerly much prescribed in this disease as an emetic, but it fell out of fashion until revived recently by Dr. Fordyce Barker. The author's experience in its use is, in the main, in accord with the much more extended experience of Dr. Barker. Administration. — As the yellow subsulphate of mercury has but little taste, it is easily administered to children. It should be prescribed in the form of powder, rubbed up with sugar of milk. The dose varies from two to five grains. Dr. Barker makes the useful suggestion that powders of this preparation, labeled " croup-powders," should be kept in every household, the children of which have a tendency to attacks of croup. It should be given when the first symptoms manifest them- selves, and its repetition will be governed by the state of the breathing. Alumen. — Powdered alum is a safe, efficient, but slow emetic. About a half -hour usually elapses after it is swallowed before the eme- sis occurs. It acts mechanically, produces no considerable nausea, and leaves behind no depression. As an emetic, its only use is in croup and diphtheria, administered with the view to cause a detachment of the false membrane. Some effect has been ascribed to the local action of SYSTEMIC EMETICS. 621 the alum in its passage along the throat, but this opinion is scarcely tenable. Administration. — A teaspoonful of powdered alum may be ad- ministered in sirup, honey, or mucilage. It can be repeated, if need be, every half -hour. Sinapis. — Mustard is a stimulant, local emetic. It acts promptly and efficiently. In emergencies, other emetics not being available, it. may be employed in narcotic and other forms of poisoning. As an emetic it is especially adapted to depressed conditions of the system — for, while it causes vomiting, it stimulates the action of the heart. When, therefore, an emetic is indicated, and at the same time the cir- culation is feeble, the surface cold, and the functions of animal life oppressed, musifcard should be used. Administration. — A tea- to a dessert-spoonful of powdered mus- tard should be stirred up in a tumblerful of tepid water, and quickly swallowed. The irritant action of the mustard may be limited, and its emetic action promoted, by the free use of diluents. Scilla. — Squill is never employed as an emetic by and of itself. It is harsh and rather slow in action. In the form of the compound sirup of squills, it is not unfrequently used for this purpose, especially in domestic practice, but the emetic property of this combination is due chiefly to the tartar-emetic which it contains. SYSTEMIC EMETICS. Apomorphine. — Apomorphinw Hydrocliloras. — Hydrochl orate of apomorphine. The hydrochlorate of an artificial alkaloid obtained by the action of strong acids upon morphine contained in closed tubes and subjected to a somewhat elevated temperature. It is obtained also by the action of chloride of zinc in solution on morphine. It is a whitish powder, which becomes greenish by absorption of moisture. It is solu- ble in water, and it may, therefore, be administered in this menstruum. Dose, gr. fa to gr. -J. If given hypodermatically, gr. fa is sufficient ; if by the stomach, gr. -J. As it undergoes important changes when in contact with water, the solution for hypodermatic use should be made when required. Physiological Actions. — Whether injected under the skin or taken into the stomach, apomorphine causes vomiting. The rate at which it moves to, affect the stomach depends somewhat on the dose administered. From five to twenty minutes usually elapse after the hypodermatic injection before vomiting begins. The act of vomiting is preceded by very little nausea, the contents of the stomach are usu- ally thoroughly evacuated, and the vomiting recurs a few times at in- tervals of a quarter to a half hour. In young subjects very consider- 622 EVACUANTS. able depression has been observed to be produced by it, and dangerous symptoms of cardiac paralysis have followed its emetic action in a few instances. These clinical facts seem to contradict the experimental observations of Siebert and Moerz, who have shown that apomorphine does not affect the blood-pressure, and that the pulse rises when emesis comes on, reaches its maximum during vomiting, and declines in the interval. The cardiac depression which has been observed, clinically, may have been the result of idiosyncrasy, yet we should not lose sight of the fact observed by Harnack, that in cold-blooded animals it may be produced experimentally. Apomorphine causes at first increased rapidity of the respiration, afterward diminishes the force and depth of the movements, and final- ly arrests them. As this result occurs when the vagi are divided, the drug must necessarily first excite and afterward exhaust the irritability of the respiratory center. Apomorphine has no appreciable influence on the temperature. As respects its influence on the nervous system, apomorphine is at first strongly excitant. Afterward it causes muscular tremblings, fol- lowed by paralysis and convulsions. The muscular irritability is im- paired but not destroyed, and the functions of motor and sensory nerves remain intact ; hence it may be concluded that the convulsant action of this agent is due to a direct impression on the spinal cord (the spasm-center). Therapy. — Apomorphine is indicated as an emetic when swallow- ing is difficult or impossible, and when very prompt action is neces- sary. As it produces vomiting by its spinal action, profound narcosis will prevent it, and hence, in narcotic poisoning, it may fail of effect unless administered before narcosis has supervened. It is a suitable emetic when it is desired to empty promptly an overloaded stomach. It is to be preferred to all emetics which must be introduced into the stomach, when this viscus is in a state of inflammation, for it is best given subcutaneously. Apomorphine has been administered as an emetic in suffocative catarrh, to empty mechanically the bronchial tubes, but it produced serious depression — a result which might have been a priori predicted, since this drug exerts a paralyzing action on the respiratory organs. It has also been given as an expectorant, but on insufficient data, for it does not seem to have an effect upon the vagi, and, as above stated, at first it excites the respiration movements, and afterward paralyzes them. As compared with its congeners, morphine and codeine, it is more excitant than morphine and codeine, and without their hypnotic and anodyne properties. As respects its convulsant action in animals, it has close physiological relations to narcotine and thebaine. Some clini- cal experiences have shown (Riegel und Bohm) that apomorphine causes heaviness in the head, giddiness, drowsiness, yawning, mental SYSTEMIC EMETICS. 623 hebetude, etc. The trials in which these results were noted were made with Merck's preparation of apomorphine.

Ten grains contain one grain each of ipecac and opium, and eight grains of sugar of milk. This preparation has already been discussed in the article on opium, and requires no con- sideration here. Composition. — Ipecacuanha contains an active principle, designated emetina or emetine. This exists in the bark of the root, in combina- tion with a peculiar acid — ipecacuanhic acid. The alkaloid is found in the root in a proportion somewhat less than one per cent. It is a bitter, inodorous, and amorphous substance, colorless, and alkaline in reaction. It is freely soluble in chloroform, and only slightly so in ether. Ipecacuanhic acid is a glucoside, and is chemically related to kinic and caffetannic acids. 624 EVACUANTS. Antagonists and Incompatibles. — The salts of lead and mer- cury, the vegetable acids, and astringent infusions, are incompatible. The tannate of emetine is extremely insoluble. Bismuth, carbolic acid, hydrocyanic acid, and narcotics generally, hinder its emetic action. Synergists. — The emetics — those by local action and the systemic — favor the vomitive action of ipecac. Its effects on the skin and bron- chial mucous membrane are promoted by opium, warm diluents, etc. Physiological Actions. — Inunctions of ipecacuanha excite very considerable irritation of the skin : at first, small, isolated pustules ap- pear, and these are followed by large pustules and ulceration (Duck- worth). When applied to the mucous membrane of the nares, it pro- duces a sensation of heat, and causes sneezing. Some persons are so susceptible to its action that the smallest quantity inhaled will induce an asthmatic paroxysm. Administered by the stomach in small doses (from one eighth to one quarter of a grain), ipecacuanha acts as a stomachic tonic, and probably increases the gastric secretions. In larger doses (from five grains to a scruple), it is nauseant and emetic ; but the sickness which it causes is not severe, and the vomiting is not accompanied nor fol- lowed by much depression. Its action as an emetic is rather slow, from twenty minutes to a half-hour being required, and is not per- sistent. Repetition of large doses will, in most cases, but not invari- ably, produce a condition of tolerance, when vomiting does not occur, but a cathartic action is induced, the stools having a peculiar bilious character, appropriately designated " ipecacuanha-stools." Both vomit- ing and purging are sometimes produced by an emetic of ipecacuanha. Like other nauseants and emetics, ipecac increases the secretions of the broncho-pulmonary mucous membrane, and is, therefore, held to possess expectorant properties. More than any other agent of the class, it relaxes the skin, and promotes cutaneous transpiration. Ipecacuanha exerts but little influence over the circulation. In ani- mals, lethal doses of emetine cause death by paralysis of the muscles of respiration, the heart continuing in action after the cessation of the respiratory movements (D'Ornellas). The temperature of the surface falls, but the internal temperature remains the same, or rises somewhat, owing, it is said (D'Ornellas), to the irritant action of the agent on the intestinal mucous membrane. In the post-mortem examination of animals killed by emetine, very considerable gastro-intestinal irritation is found. The lungs are some- times seen to be hypersemic and presenting patches of hepatization, and sometimes exsanguine, but the former condition is more frequently observed. As the most common state of the lungs, caused by lethal doses of ipecac, is similar to that which is induced by section of the vagi, it is a reasonable conjecture that it has a special action on these nerves — according to Chouppe, on the terminal filaments of the vagi. SYSTEMIC EMETICS. 625 The elimination of emetine takes place in large part by the gastro- intestinal mucous membrane, and it is found in the secretions. Therapy. — For ordinary purposes no emetic is more safe and effi- cient than ipecacuanha. As. it causes but little depression, and is free from irritant effects in ordinary doses, it may be given in conditions of the system in which tartar-emetic and the other mineral emetics are inadmissible. When the stomach is to be relieved of undigested ali- ment, ipecacuanha is the most suitable emetic. Attacks of acute indi- gestion, migraine, and the so-called bilious sick-headache, may not un- frequently be cut short by an ipecac-vomit. The good effects of the vomitive treatment are, not unfrequently, most strikingly exhibited in the beginning of continued fevers, the eruptive fevers, erysipelas, and periodical fevers. It has been alleged that fevers are sometimes " aborted " in this way. In denying the possibility of such results, it must be admitted that clinical experience has shown the good effects of the practice on the subsequent course of the malady. Formerly an ipecacuanha- emetic was much more frequently emplyed at the out- set of fevers than is the fashion at present, and the author is con- vinced that this mode of treatment should be resorted to now in suit- able cases. The indications for the use of emetic doses of ipecac- uanha, in the fevers above named, are these : a heavily-coated tongue, much nausea and ineffectual efforts to vomit, a strong sense of epigas- tric oppression, icterus or an icterode hue of the surface, a hot and dry skin, acid and turbid urine. When these symptoms are present in cases of malarial fever, the antiperiodic remedies will be much more effective in their action if their administration has been preceded by an ipecacuanha-emetic. In all the cases in which emetics are employed for mechanical effects, as in membranous croup), capillary bronchitis, foreign bodies lodged, etc., ipecacuanha may be used. In croup it is not so effective as the yellow subsulphate of mercury ; in capillary bronchitis, as tartar-emetic; but, as respects the latter disease, ipecacuanha is to be preferred in the very young or very old, and in those debilitated by any cause. In the domestic treatment of laryngismus stridulus an emetic dose of the sirup of ipecac is the most usual remedy. As an emetic, twenty grains of the powder of ipecacuanha may be diffused in a cup of warm water, and a tablespoonful of the mixture exhibited every fifteen minutes until emesis occurs. Two grains may cause vomiting ; and four grains will usually act efficiently ; hence a good method of proceeding, when an emetic effect is desired, is to ex- hibit a powder of four grains in a tablespoonful of warm water every fifteen minutes until vomiting occurs. The action will be facilitated by drinking freely of warm water ; but, if the systemic impression of the ipecacuanha is desired, the patient should retain the recumbent post- ure, and all fluids should be withheld. If the cathartic as well as the 40 626 EYACUANTS. emetic action is sought for, some weak animal broth should be given when the stomach is emptied of its contents. If free action of the skin is to be promoted, as soon as the vomiting has ceased warm aromatic infusions should be administered, and the patient should be covered with blankets. It has long been known that ipecacuanha, in small doses, has the power to arrest certain kinds of vomiting. Attention has recently been recalled to this curious fact. It is in nervous vomiting more especially that this remedy is useful : for example, in the vomiting of pregnancy, vomiting of. drunkards, vomiting of migraine, etc. A minim of the vinum ipecacuanha?, given every half -hour or hour in a little water, will sometimes relieve these cases in a very remarkable manner ; but it very frequently fails, and there are no indications at present known which will enable the practitioner to determine beforehand whether it will or will not be successful. It is a singular fact, showing the remarkable phases through which professional opinion passes, that ipecacuanha, which was introduced at the close of the seventeenth century as a remedy for dysentery, after a time ceased to be employed in this disease, but has again been restored to the estimation in which it was originally held. Epidemic dysentery, especially of malarious and tropical countries, is the form of the disease to the cure of which ipecacuanha seems best adapted. The author has used it with much success in acute dysentery, as it occurs in the interior valley of this continent. When the characteristic ipecacuanha-stools are produced, the tormina and tenesmus cease, and the dejections soon become feculent ; the skin, previously dry and hot, becomes moist and cool, and a refreshing calm is experienced. Large doses of ipecacuanha are required in the treatment of acute dysentery. In the severe attacks of tropical regions, from twenty to sixty grains are given for the initial dose, and the quantity subsequently administered depends on the effect — usually about twenty grains every four, six, or eight hours. It is im- portant to establish tolerance of the remedy as speedily as possible. If the first dose be rejected, subsequent ones may be retained. Various expedients may be resorted to in order to secure the retention of these large doses. The ipecacuanha may be combined with some opium and aromatic powder : 1$, Ipecacuanha?, 3 ss ; opium, gr. j ; pulv. aromat., grs. v. M. Ft. pulv. no. j. After the dose of ipecacuanha is adminis- tered a sinapism may be applied to the epigastrium, and an enema of laudanum and starch, or the subcutaneous injection of morphine, may be practiced. Milk is an excellent vehicle for the administration of ipe- cacuanha. In the cases of dysentery treated on this plan by the author, he has found that doses of fifteen grains, given in milk, were generally pretty well borne. It not unfrequently happens, however, that toler- ance can not be established, and the remedy must then be abandoned. Some patients so object to the nausea produced by it as to be reluctant SYSTEMIC EMETICS. 627 to take it, and others, after one trial, decline to continue the treatment. Notwithstanding these drawbacks, it must be conceded that ipecacu- anha is a most valuable remedy in epidemic and sporadic dysentery. It has been shown that in India, before the introduction of this method of treatment, the mortality from dysentery was about 79 '6 per one thousand of cases ; but, since the use of ipecacuanha has been general- ized, the mortality has fallen to 20*15 per one thousand of cases. Ipecacuanha has also been used with success in chronic dysentery, but, in the author's experience, it is by no means so beneficial as in the acute. It succeeds best in those cases which are the outgrowth of acute attacks, and in which the intestinal ulcerations are not far advanced. The rules for its administration are the same in chronic as in acute dys- entery. In the summer dysentery and diarrhoea of teething children ipecacuanha is often extremely serviceable. The special indication for its use is the occurrence of greenish stools, containing mucus and some- times blood. These stools are usually voided with much pain and straining. At the same time the skin is harsh and dry, the tongue rather dry and pasty, or glazed, and there is great thirst, although little or no fever may be present. Ipecacuanha changes the character of the stools, induces perspiration, and allays the thirst and dryness of the mouth. From two to five grains every two hours may be given in these cases, or it may be administered with pepsin, oxide of zinc, bismuth, or other remedies, fy Ipecacuanhas, grs. xij ; bismuthi subcarb., 3 j ; pepsinae sacch., 3 ss.

It has been successful in haemoptysis, epis- taxis, menorrhagia, postpartum haemorrhage, etc. As Peter has ob- served, " the vomitive medication " (ipecacuanha) " arrests not only haemoptysis but all kinds of haemorrhage, and is, therefore, a general antihaemorrhagic medication." In haemorrhages the ipecacuanha should be given in frequently-repeated doses until vomiting ensues ; usually, when this effect is produced the haemorrhage ceases.

Sig. : Thirty minims to a teaspoonfid at a dose, as required. The author has witnessed excellent results from this combination in hae- moptysis and menorrhagia. In the treatment of post-partum haemor- rhage, the most suitable combination is fluid extract of ipecacuanha and fluid extract of ergot. Trousseau strongly urges the employment of ipecacuanha in post-partum haemorrhage, and, indeed, in the various accidents which occur in the puerperal state, among which he desig- nates gastro-intestinal irritation, suppression of the lochia, subacute metritis, pelvic cellulitis, bronchial catarrh, subacute pneumonia, etc. " He has not observed the least ill-result from this practice ; on the 628 EVACUANTS. contrary, in the most of these cases, he has obtained either a cure or a notable amendment " (Trousseau et Pidoux). Certain acute affections of the broncho-pulmonary mucous mem- brane are much benefited by non-emetic doses of ipecacuanha ; for example, acute catarrh of the nasal and bronchial mucous membrane, hay-asthma, capillary bronchitis. An emetic dose will cut short an attack of laryngismus stridulus. An occasional emetic gives great relief in whooping-cough, when there is profuse bronchial secretion. Non-emetic doses of the fluid extract (tt[ j — t\[ iij) diminish the violence of the spasms in this disease. Nauseating and emetic doses are ser- viceable in the attacks of spasmodic asthma, but the good effects of the remedy are lost by repetition. Ordinary colds, especially in children, are benefited by doses sufficient to produce slight nausea but not vomit- ing. A troublesome cough at night, which prevents sleep, may not unfrequently be arrested by a dose at bed-hour of some one of the ipecacuanha preparations. For these various purposes the wine or the fluid extract may be used, but the latter preparation is much more trustworthy and effective than the former. Authorities referred to : Chouppe, M.

Purgatives are divisible into several groups, according to the nature of their action. Laxatives are medicines which stimulate the intestinal movements, without increasing to any considerable extent, at least, the intestinal secretions. Saline Purgatives excite increased secretion, while at the same time they hasten the peristaltic action. The dejections which are produced by them are loose and watery. Mercurial Purgatives, chiefly calomel and blue mass, exert an in- fluence peculiar to themselves. "Without expressing an opinion at present, for or against their supposed cholagogue effects, the author believes that they differ so much in their action from other purgatives as to be appropriately placed in a separate class. Tonic-astringent and Resin-hearing Purgatives. — These affect the liver and the glandular appendages of the mucous membrane, and in- crease the tonicity of the muscular layer of the intestine. They in- crease the proper secretion of the glands, and do not merely cause an outward osmosis of fluid from the vessels. Hydragogue Purgatives act with great energy, and not only in- crease the glandular secretions, but cause a very abundant outward diffusion, so that the dejections which they produce are extremely watery. This group of purgatives also excite very rapid and violent peristaltic movements. Laxatives. — Manna. — Manna. The concrete, saccharine exudation, in flakes, of Fraxinus ornus Linne (Nat. Ord. Oleacece). Dose, 3 j — 1 ij, according to age. Composition and Properties. — Manna has a sweetish, rather mawkish taste ; is soluble, when pure, in three parts of cold water, and in its own weight of boiling water. It contains a sugar — manna- sugar or mannite, which constitutes from seventy to eighty per cent of the best specimens of manna. It is said to contain dextrin, or a mucilage having similar reactions, and ether extracts from it in small quantity a slightly acrid, reddish-brown resin, on which the laxative property of manna probably depends. • Actions and Uses. — Manna is a very mild laxative, but, when administered alone, is apt to cause griping. It is rather slow in its operation, but is free from irritating qualities, and leaves no unpleas- ant after-effects. It is most frequently combined with other purga- tives — senna chiefly — the operation of which it aids, and at the same time renders less drastic. It is rarely given alone, and only to chil- 630 EVAOUANTS. dren and pregnant women. Formerly it was used as a laxative in hemorrhoidal affections. Sulphur. — Sulphur lotum (washed sulphur). Sulphur sublimatum (sublimed sulphur). Washed sulphur only should be used as a laxa- tive. Sublimed sulphur contains a trace of acid which imparts to it a griping quality. Dose, 3 j — 3 iij. Actions and Uses. — Sulphur is insoluble in water, but dissolves in alkaline solutions and in the volatile and fixed oils. In the small in- testine, sulphur is placed under favorable conditions for absorption. That it does enter the blood is proved by the fact that it appears in the perspiration, urine, milk, etc. Silver coins, carried in the pockets of those taking sulphur, are discolored by the formation of the sul- phide of silver. Considerable sulphureted-hydrogen gas is produced as a result of the chemical changes in the intestines, and a quantity of offensive flatus is an unpleasant sequel of its administration. The in- testinal secretions are somewhat increased by it, and the stools are therefore softer. It is a very mild laxative. Combination of sulphur and bitartrate of potassa or magnesia is occasionally resorted to, es- pecially in domestic practice, for the purpose of increasing the laxative action. Sufficient attention has already been paid to the sulphur compounds, and it only now remains to speak of sulphur as a laxative. It is used chiefly to render the stools softer and more easily voided in cases of hmmorrhoids, fissures of the anus, and after surgical operations about the pelvic organs. It is used also as a laxative in skin-diseases, chronic rheumatism, sciatica, and lead-cachexia, conjoined usually with sul- phur-baths, the sulphurous mineral waters, and other appropriate med- ication. Pulvis Glycyrrhiz^e Compositus is an efficient laxative. It is made as follows : Senna-leaves, eighteen parts ; licorice-root, sixteen parts ; fennel-seeds, eight parts ; washed sulphur, eight parts ; re- fined sugar, fifty parts. M.

Dewees's for- mula.) Dose, one fourth to one teaspoonful. Actions and Uses. — A mild antacid laxative. In the stomach it neutralizes any free acid it meets with, and the resulting salt has a laxative action. It is used to correct acidity, the carbonate being pre- ferred when there is an irritable state of the stomach, because the carbonic acid, which is set free by the action of the stomach acid, is a local sedative and anodyne. If magnesia does not enter into combi- nation with the stomach acid, no laxative effect is produced. Under these circumstances a solution of citric acid or lemonade, taken after the magnesia, will cause it to act. Magnesia is a useful antacid and laxative in sick-headache, especially when accompanied by acidity and constipation. It has been employed also in gouty affections, and in Uthiasis (uric acid) ; but it is much inferior to the potash salts in these affections. In the intestinal indigestion of infants, attended with flatulence, magnesia is much prescribed in conjunction with car- minatives. Dewees's formula for flatulent colic and diarrhoea in in- fants has been made official, and is given above as Mistura Magnesia} et Asafcetida}.

It is unsafe to use magnesia in large quantity for lengthened peri- ods, owing to the fact that it may form intestinal concretions — a hy- drate of magnesia. Instances of this kind have been reported. Freshly-precipitated hydrate of magnesia is an antidote to arseni- ous acid in solution, but it is not so effective as the hydrated sesqui- oxide of iron. Oleum Ricini. — Castor-oil. Sidle de ricin, Fr. ; Castorol, Ger. A fixed oil expressed from the seed of Ricinus communis Linne (Nat. Ord. Euphorbiacece). Dose, 3 j — J j. Properties and Composition. — Castor-oil has a pale amber-color, a rather nauseous taste, and is quite viscid. Cold increases the viscid- ity. It has a specific gravity of about 0*96. It contains several fatty 632 EVACUANTS. acids — -palmitic and ricinoleic — the latter peculiar to castor-oil. The seeds appear to contain a drastic constituent, which is more powerfully- purgative than the oil. The purer the oil, the less active its purgative property. Actions and Uses. — Castor-oil is a mild but very certain and effi- cient laxative. It operates in from four to six hours, causing but little pain, and producing copious stools. It increases but slightly the in- testinal secretions — hence the stools are not very liquid. Its purgative principle enters the blood, and the milk of the mother may in this way acquire a purgative property. It does not appear to have any effect upon the hepatic secretion. Rohrig's experiments, which dem- onstrated this point, have been confirmed by the subsequent investi- gations of Rutherford and Yignal. After the action of castor-oil has been completed, it may not unfrequently be seen floating on the stool ; yet Buchheim (Husemann) has been unable, after careful examination of the f seces, to discover in them castor-oil or any of its derivatives. Castor-oil is justly held in great esteem as a laxative for children, for pregnant ico)nen,for the puerperal state. When hardened f wees and irritating substances are to be removed from the intestinal canal, castor-oil is the most efficient purgative compatible with safety. When inflamed hemorrhoids, fissures of the anus, or surgical operations on the pelvic viscera, require the use of a mild, certain, but unirritating laxative, castor-oil should be selected. Unfortunately, its taste is so repugnant to many palates, that no considerations will overcome the disgust which it excites. No remedy is more useful in the diarrhoea of children, induced and maintained by undigested aliment or irritat- ing secretions. It is judicious practice, in these cases, to give a laxa- tive dose of castor-oil to empty the canal, and follow it with an opiate or enema of laudanum. The dysentery of children, and sporadic dys- entery of adults, especially after the more acute febrile symptoms have subsided, are generally very successfully managed by an emulsion of castor-oil : ty 01. ricini, f j ; mucil. acacise, syrup, simplicis, aa J ss ; aquae cinnamomi, J ij. M. Sig. : A tablespoonful every four to six hours. In cases of dysentery, when there are much pain, tenesmus, and frequent passages, ten to twenty drops of laudanum may be added to each dose ; when there are much depression, a low state of the ar- terial tension, and a dry, glazed tongue, five drops of turpentine may also be added. A poultice made of the leaves of the castor-oil plant applied to the breasts, it is said, has the power to promote the secretion of milk. Warm applications to the mammas undoubtedly stimulate their func- tional activity, but it is questionable whether castor-oil leaves have a special galactagogue property. It is said, however, that the inhabit- ants of the Cape Verd Islands have long been acquainted with this supposed property. The internal use of a fluid extract of the leaves CATHARTICS. 633 has also, it is supposed, the power to determine an increased secretion of milk. Jaborandi will probably prove to be more effective in this respect than the ricinus communis. Saline Purgatives. — Many of these have been discussed elsewhere ; some of them are no longer employed in medical practice. The sul- phate and the citrate of magnesium may be regarded as typical repre- sentatives of the class, and hence, in a statement of their physiological actions and therapeutical applications, may be comprehended all that is of immediate and practical value on the subject. Magnesii Sulphas. — Sulphate of magnesium. Sulfate de magnesie, Fr. ; BittersalZy Ger. In colorless crystals, which slowly effloresce on exposure to the air, and are very soluble in water. Dose, 3 j — ? j. Magnesii Citras Granulatus. — A white, coarsely-granular salt, del- iquescent on exposure to air, odorless, having a mildly acidulous, re- freshing taste, and an acid reaction. Soluble with copious efferves- cence in two parts of water at 60° Fahr. ; almost insoluble in alcohol. Dose, 3 j — 3 iv. Liquor Magnesii Citratis. — Solution of citrate of magnesia. Dose, § iv — 1 viij. A tablespoonful of the granular salt added to a half- tumblerful of water, and drunk during effervescence, is the quantity and the form in which it may also be taken. The bottled solution, which is also highly effervescent, must be drunk immediately on being poured out. It is a pleasant drink, and, when properly prepared, an active cathartic. Physiological Actions of Saline Purgatives. — As a general rule, saline cathartics are easily borne by the stomach ; especially is this true of the Epsom salts. The purgative action is due chiefly to increase of the intestinal secretions, and hence the stools are large and watery. Thiry and Radziejewski had apparently demonstrated that all purgatives acted by increasing the peristaltic movements, but ex- actly opposite results have been obtained by Moreau, whose observa- tions have been confirmed by Vulpian and Brunton. The conclusion reached by the last-named observer is expressed as follows : " Such positive results as these seem to prove that purgatives do cause a flow from the intestinal wall, quite as conclusively as experiments with Thiry's fistula do the opposite ; and, as the conditions under which the purgatives act on the intestines more nearly approach the normal in Moreau's than in Thiry's experiments, there can be little doubt that purgatives produce a decided secretion of fluid from the intestines, as well as accelerate peristaltic movements." Of the agents employed by Brunton in his experiments — croton-oil, elaterin, gamboge, jalapin, and sulphate of magnesia — the greatest secretion was caused by the latter. The results of the best directed experiments are, therefore, in 634 EVACUANTS. accord with clinical observations, and it may hence be considered as established that saline cathartics produce an outpouring of fluid into the intestinal canal. This outward osmosis occurs chiefly from the vessels, and is not truly a secretion of the glandular appendages of the mucous membrane. Therapy. — The saline purgatives are indicated in acute inflamma- tory affections, as a part of the denutrition treatment. If the arterial tension is abnormally high, purgatives, especially the salines, lower it, as the sphygmographic tracings show. When a considerable quantity of serum is withdrawn from the intestinal vessels, the blood-pressure is necessarily diminished elsewhere (Brunton). Free transudation from the blood-vessels of the intestinal canal lessens the amount of work which the kidneys have to do, and, if these organs are hypeneraic, re- moves the congestion. Saline cathartics are therefore very important remedies in the treatment of renal and cardiac dropsy. Free purga- tion, also, influences the condition of the kidneys by reflex action. As a result of the lessened hyperemia of the kidneys, the diminution of the blood-pressure, and the reflex stimulation of these organs, the ac- tion of a purgative is often followed by greatly -increased activity of the renal function. In ascites from obstruction of the portal circula- tion, saline cathartics are even more conspicuously beneficial than in general dropsy — for in this case they affect directly the organs in- volved. Cholcernia, urosmia, oedema of the brain, increased intra- cranial blood-pressure from any cause, are conditions requiring the use of active saline cathartics. The most important applications of saline cathartics are in the treat- ment of various intestinal disorders. When the stomach is irritable, and the intestines inflamed, no other purgative is so well borne as Ep- som salts, and its use may be resorted to when any other agent of the kind would be inadmissible. Impactio?i of the ccecum, and typhlitis resulting from this cause, may be removed by the proper administration of this remedy. It is unsafe, by active and drastic purgatives, to at- tempt to unload the bowel — for these harsh measures will only aggra- vate the existing inflammation. Epsom salts will liquefy the fecal masses and deplete the vessels, and thus remove the obstruction with- out causing any irritation. Small doses frequently repeated are more suitable than a large purgative dose. Usually about a teaspoonful in a wineglassf ul of water, every three hours, will be the quantity required. Perityphlitis and the peritonitis arising from inflammation and perfora- tion of the appendix vermiformis are conditions in which purgatives of any kind are inadmissible. The constipation which accompanies lead-colic can be overcome by Epsom salts. $ Magnesii sulphatis, § j 5 acidi sulphuric, dil., 3 j ; aquae, § iv. M. Sig. : A tablespoonfid every three hours. As Brunton has pointed out, the administration of Epsom salts is a very important CATHARTICS. 635 expedient in the treatment of the saturnine cachexia. Lead, as well as other minerals, mercury and copper, for example, is eliminated with the bile, and is discharged into the intestine, where it is again ab- sorbed. For an indefinite period, therefore, the absorption and dis- charge of the same metal may be going on ; and hence the utility of giving purgative doses of Epsom salts during the treatment of lead- poisoning. The most efficient treatment of acute dysentery is by the adminis- tration of sulphate of magnesia. It is especially adapted to the acute stage when there are fever, pain, tenesmus, and stools of mucus and blood. It lessens the hyperemia and causes fecal evacuations, with the result of relieving the pain and the distressing straining. It is admin- istered as follows : Take a sufficient quantity of sulphate of magnesia to saturate eight ounces of water, and to this saturated solution add one half ounce of diluted sulphuric acid. The dose of this is a table- spoonful every hour or two, in a wineglassful of water, until it oper- ates. Sulphate of morphine may be combined with it, or starch ene- mata with laudanum may be employed. The bleeding from hemorrhoids may sometimes be arrested by the above-described solution of Epsom salts and sulphuric acid, especially if the state of the hemorrhoidal vessels be due to constipation. Uterine hemorrhage caused by the presence of a fibroid, or by subinvolution, and congestion of the pelvic viscera, are not unfrequently relieved by the same agent when other agents apparently more powerful fail. When congestion of the pelvic organs, constipation, and anaemia coex- ist, the following is an efficient remedy : fy Magnesii sulphat., § j ; f erri sulphat., manganesii sulphat., aa 3] ; acid, sulphur, dil., 3 ij ; aqua?, J iv. M. Sig. : A tablespoonful in a wineglassful of water each morning before breakfast. For habitual constipation in those of full habit and active circulation, a daily morning dose of a teaspoonf ul of Epsom salts is often a permanently effective remedy. The disagreeable taste of Epsom salts is perfectly well covered by coffee. Boil for two minutes in an earthen vessel one ounce of sul- phate of magnesia and two and a half drachms of roasted coffee in a pint of water ; then remove from the fire, allow it to " draw " for a few minutes, and strain. The other saline purgatives belonging to this group are : Sodii Sutyhas, sulphate of sodium, Glauber's salts, Potassii Sulpthas, sulphate of potassium ; but both of these have long since ceased to be used. Sodii Phosphas, phosphate of soda, Potassii et Sodii Tartras, tartrate of potassium and sodium, Ro- chelle salts, and Pidvis Ejfervescens Compositus, effervescing aperient powders or Seidlitz powders, have been considered elsewhere. 636 EVACUANTS. Potassii JBitartras, bitartrate of potassium, cremor tartar, may also be regarded as a member of this group, although it has but feeble pur- gative property. Mercurial Purgatives. — As the actions and uses of the mercurial preparations have been sufficiently discussed elsewhere, little need be said in addition as respects their applications as purgatives. Hydrargyri Chloridum Mite. — Mild chloride of mercury. Calo- mel. Dose as a cathartic, gr. j — grs. x. Massa Hydrargyri. — Mercurial pill. Blue mass. Dose, grs. v — grs. xv, as a cathartic. Actions and Uses. — These mercurial purgatives are rather slow in their action. A dose at bedtime will usually operate during the course of the following morning. One grain of calomel or five grains of mercurial pill will produce distinct purgative effects in most persons in about twelve hours, unless there be considerable habitual torpor of the bowels. They are apt to cause griping pains, nausea, and even vomiting, when the purgative effects begin. First brownish and bad- smelling, and afterward greenish stools, supposed formerly to be char- acteristic of the mercurial action, are produced. Much heated discus- sion has arisen as to the cholagogue action of mercury. Without entering into details on this point, it may be admitted that bile- elements are found in the stools from the action of mercury, as they are unquestionably found in the stools caused by some other purga- tives. The presence of bile-elements in the faeces discharged, only proves that mercurial cathartics swept them out with the other contents of the intestinal canal, and does not prove that an excitant action was exerted on the secretory function of the liver. The stored- up bile in the gall-bladder may be emptied into the intestine in obe- dience to a reflex influence transmitted from the intestinal mucous membrane irritated by the purgative. Experimental investigations must be invoked to determine the question whether mercurials actu- ally stimulate the liver to the production of an increased quantity of bile. In another place the experiments of Hughes Bennett's Edin- burgh Committee have been stated. Since the report of that commit- tee has made its appearance, the very accurate and painstaking inves- tigations of Rutherf ord\ and Yignal have been published. Rohrig had already determined as the result of his experiments that " with large doses (twenty grains for a dog) it rarely happened that the secretion of bile was recalled after it had come to a standstill, although this agent can increase the secretion when it is only diminishing." Ruth- erford and Vignal arrived at the following conclusions as the results of their experiments with calomel : " 1. An increase of the biliary se- cretion followed the administration of two successive doses of ten grains of calomel in one case (Experiments 30). Diminution of the CATHARTICS. G37 secretion was the only result of the same doses given under similar circumstances- in other two cases (Experiments 31 and 32) ; and it was the most definite result of the administration of four successive doses of three grains in another case (Experiment 33). 2. In all the four experiments the calomel had a purgative effect. 3. Analysis of the bile secreted during the calomel purgation in Experiment 33 showed that, notwithstanding a diminution in the quantity of bile secreted, the percentage amount of solids had become less." The results of experiment render it probable that mercurials do not in- crease the secretion of bile in animals, but we are not without con- firmatory evidence in the human subject. In the cases of biliary fis- tulas (accidental) observed by Westphalen and Ranke, no increase, but rather a diminution in the amount of bile, followed the exhibition of calomel in purgative doses. That the purgative action of mercurials has a distinctive and pe- culiar quality, a vast clinical experience attests. The stools are rather different from those caused by other purgatives, and the therapeutical effects are, it is generally held, sui generis. Whatever peculiarity per- tains to the purgative action of mercurials is probably due to the fact that they greatly increase the elimination of the products of waste, or retrograde metamorphosis of tissue, by the intestinal glandular appa- ratus. As a purgative, the use of mercury is restricted to those cases in which a deficiency of bile is supposed to be the cause of the morbid state — clay-colored stools, jaundice from catarrh of the gall-ducts ; and to those cases, singularly enough, in which bile is supposed to be in ex- cess — biliousness, so called, jaundice from excessive production of bile, etc. For further remarks on the actions and uses of mercury the reader is referred to the section on remedies used to promote destruc- tive metamorphosis. TONIC-ASTRINGENT AND RESIX-BEARIXG PURGATIVES. Senna. — Senna. The leaflets of Cassia acutifolia Delile (Alexan- dria senna), and of Cassia elongata Lemaire-Lisancourt (India senna), (Nat. Ord. Eegumi?iosce, Ccesalpinacece) . (IT. S. P.) Feuilles de sene, Fr. ; Sennesblatter, Ger. Confectio Sennas. — Confection of senna. (Senna, coriander-seed, licorice, figs, prunes, tamarinds, cassia.)

Syrupus Sennce. — Sirup of senna. Dose, 3 ss— 3 ij. Composition. — The active constituents of senna prove to be a pe- culiar colloid body, and an acid, to which has been given the name 638 EVACUANTS. cathartic acid. It has been shown that " cathartate of ammonia pos- sesses, in a concentrated form, the purgative activity of the original drug." Two bitter principles have been obtained from senna — senna- crol and sennapicrin. It contains also a peculiar sugar — catharto- mannite. Actions and Uses. — The taste of senna is nauseous and bitter. In infusion — the form in which it is most usually prescribed — it is most disagreeable in odor as well as taste. It produces a sense of warmth in the stomach, and causes much flatulence and griping, which may, however, be prevented by combination with aromatics. Its active principles are absorbed, and the milk of the mother taking senna ac- quires a purgative property. It is a very efficient cathartic, producing copious liquid stools in about four hours. It does not cause inflamma- tion or hypercatharsis, and its purgative action is not followed by in- testinal torpor and constipation. It were, therefore, a very safe and serviceable cathartic, if it were not so disagreeable. The confection of senna is a palatable preparation, and a mild laxa- tive, operating without any disturbance. It is used chiefly to correct the constipation of 'pregnancy ', but it is highly prized by some patients as a remedy for habitual constipation. It is also taken to procure soft and easy evacuations in hemorrhoids, fissures of the anus, etc. A large bolus (one hundred and twenty grains), taken at bedtime, will operate gently on the following morning. The fluid extract of senna is a form for the administration of this drug more agreeable than the infusion. These two preparations are very excellent cathartics to over- come constipation, especially when ordinary purgatives fail. The action of senna is much improved by combination with other purgatives, and with aromatics. The well-known "black draught" is an infusion of senna with sulphate of magnesia — one ounce of the latter dissolved in four ounces of the former. By the addition of coffee, the odor and flavor of senna may be rendered more tolerable. Two drachms of senna and one drachm of coffee may be infused in three ounces each of hot milk and boiling water, and the whole drunk after twelve hours. Rheum. — Rhubarb.

Dose, 3 j — § ss. Pulvis Rhei Compositus. — Compound powder of rhubarb. Dose, a teaspoonful. Composition. — Rhubarb contains a number of substances which have been isolated, but its composition has not yet been accurately determined. It contains two acids, rheo-tannic and rhewnic, a resin- ous body, phceoretin, and chrysophan, or chrysophanic acid. Physiological Actions. — In small doses, rhubarb is a tonic astrin- gent. It promotes the appetite and the digestive power, and, by virtue of its tannin, is astringent and diminishes peristalsis. As it contains also a purgative principle, in sufficient doses cathartic effects follow its administration. The stools are stained by the coloring-matters of the rhubarb, are of a yellowish-brown color, and are rather soft without being watery. After the purgative action has ended, the astringent constituents assert their power and constipation results. As the stools present an appearance to which the term " bilious " was applied, it was formerly supposed that rhubarb had the power to increase the flow of bile ; more recently it has been universally conceded that the coloring-matter of rhubarb produces the peculiar tint referred to. The latest investigations of Rutherford and Yignal have, apparently, very conclusively shown that rhubarb really possesses the property anciently ascribed to it, and that it must be placed among the cholagogue medi- cines. As it is now known to increase the flow of bile, it may be as- sumed that the intestinal secretions in general are promoted by it. These effects, which indeed are produced by all the purgatives contain- ing a resin, are probably due to phaeoretin — the rhubarb resim The coloring-matters of rhubarb stain the perspiration, milk, and urine, and the milk acquires a bitter taste and purgative properties. Therapy. — The infusion of rhubarb is frequently employed as a vehicle for the administration of alkalies and mineral acids in sto- machic disorders. In small doses, the tincture is an excellent sto- machic tonic in dyspepsia with deficient biliary and intestinal secre- tions. It is adapted to those of a relaxed habit, and is inadmissible when a hyperemia of the mucous membrane exists. Rhubarb is a remedy of the greatest utility in the duodenal catarrh, and in the catarrh of the biliary ducts with jaundice, as these maladies occur in children. The passing of whitish, pasty, or clay-colored stools, 640 EVACtJANTS. while the skin presents an earthy or jaundiced hue, is the indication for the use of rhubarb. It is true that the stools will be quickly stained, so as to present the bilious character, without any improvement having necessarily taken place in the local malady ; but it is also true that rhubarb is curative in the conditions above described. In the summer diarrhoea of children, no remedy is more generally prescribed. The aromatic sirup of rhubarb is a pleasant form in which to administer it. In this disorder, especially if the motions are sour, alkalies should be prescribed with the rhubarb. Magnesia, chalk, or sodium carbonate, may be given with the powder of rhubarb, the fluid extract, or the sirup. The following is an excellent formula in these cases : fy Infus. rhei, 3 iij ; potassii bicarb., 3 j ; tinct. cinnamomi, 3 ij ; syrp. simplicis, 3 vj. M. Sig. : A teasp>oonful every hour or two in cholera infan- tum. Diarrhoea in children or adults, due to the presence of undi- gested food, or retained irritating secretions, may not unfrequently be cured by a purgative dose of some rhubarb preparation. After the purgative effect is expended, the bowels are confined by the astringent. In acute dysentery the saline purgatives are much more appropriate than rhubarb. In habitual constipation good effects may be obtained by chewing some rhubarb-root. The astringent after-effect is, however, a decided objection to the frequent use of this remedy for this purpose. In the rhubarb-pill the astringency is counteracted by soap. The compound rhubarb-pill, which contains aloes, is a mild and efficient cathartic. Aloe. — Aloes. The inspissated juice of the leaves of Aloe Socotrina Lamarck (Nat. Ord. Liliaceai). Aloe Purificata. — Purified aloes.

CATHARTICS. 641 Pulvis Aloes et Canellce. — Powder of aloes and canella (hiera picra). Dose, grs. v — 3], (Not official.) Composition. — The odor of aloes is due to a peculiar volatile oil. It contains also a resin, and a principle, alo'ine. The composition of aloine is not precisely the same in the different varieties of aloes. The Barbadoes aloes furnishes barbaloine, the Natal aloes, natalo'lne, and the Socotrine aloes, soalo'lne. These varieties, it is supposed, consti- tute an homologous series. Actions and Uses. — Aloes has a bitter and very disagreeable taste, leaving a rather acrid after-sensation in the fauces. It is a stomachic tonic, and, like bitters in general, it promotes the appetite and diges- tion. Accordingly, it is much prescribed as a stomachic tonic in cases of indigestion with torpor of the large intestine. Irritable or inflam- matory states of the stomach mucous membrane contraindicate its employment. The recent investigations of Rutherford and Vignal have shown that aloes has the power to stimulate the hepatic functions, and to promote the flow of bile. This result is confirmatory of clinical expe- rience. In large doses (twenty grains or more) aloes undoubtedly in- creases the intestinal secretkms generally ; but, in the ordinary medici- nal laxative dose, the stools are not liquid, and are but little altered in character. The principal effect of aloes is expended on the large intestine, the peristaltic movement of which it increases. Some tor- mina is experienced when the laxative effect begins, and tenesmus, with heat and irritation of the rectum, is produced when an active purgative dose has been taken. The blood -supply to the pelvic organs is increased by aloes ; the menstrual flow becomes more abundant, and abortion, it is said, may be caused by its incautious administration ; while in the male, erections take place more fre- quently. Ten or twelve hours elapse after it has been swallowed, before cathartic effects are produced. The rate at which it moves to affect the intestinal canal is influenced less by the size of the dose than by the condition of the bowels. The purgative principle of aloes diffuses into the blood. Applied to an exposed surface, it is absorbed and purges, and the milk of moth- ers taking it acquires a purgative action. Simple jaundice, of an atonic kind, may be cured by aloes. No purgative is more efficient in constipation, dependent on weakness and impaired contractility of the muscular layer of the large intestine. Jaundice, or at least a bilious state, a coated tongue, foul breath, a tumid abdomen, and an impacted colon, are conditions frequently associated and are readily relieved by aloes. The constipation of hypochondriasis and melancholia is best overcome by the use of this agent, and, with the removal of the impacted fasces, there is not un- 41 642 EVACUANTS. frequently an improvement in the mental state. Aloes is prescribed in cerebral disorders, when purgatives are given with a view to a derivative effect. In amenorrhcea which is dependent on anaemia, aloes is prescribed, with other appropriate remedies, to determine an afflux of blood to the uterine system. Menorrhagia, occurring in debilitated and relaxed subjects, is sometimes relieved in the same way. Iron may be asso- ciated with aloes in these cases. Congestion of the pelvic viscera is a contraindication to the use of aloes, and the existence of haemorrhoids, or of a tendency therefor, has heretofore been considered an equally positive contraindication. Fordyce Barker has, however, shown that aloes has a curative power in certain cases of hemorrhoids, and nota- bly those which occur after delivery. The local condition, under these circumstances, is not one of active hyperemia, but really consists in a sluggish state of the circulation in the inferior haemorrhoidal veins. It can hardly be doubted that aloes would increase the trouble if pre- scribed for cases in which there was active congestion of the pelvic viscera. Barker also advocates the use of aloes in non-puerperal haemorrhoids, but the local condition must be suitable for the use of this remedy or the disease will be aggravated. The following are for- mulae proposed by Barker: ^ Pulv. aloes Soc, sapo. Cast., aa 3j ; ext. hyoscyami, 3 ss ; pulv. ipecacuanhae, grs. v. M. Ft. pil. no. xx. Sig. : One pill morning and evening. When the haemorrhoids are associated with an irritable rectum, and with frequent, small, teasing, thin evacuations, Barker substitutes for the hyoscyamus a small quan- tity of opium, giving also a less quantity of the aloes, as in the fol- lowing formula : fy Ferri sulph., 3] ; pulv. aloes Soc, ext. opii aq., sapo. Cast., aa grs. x. M. Ft. pil. no. xx. Sig. : One pill morning and evening. Oppolzer also used aloes as a remedy for haemorrhoids, prescribing, when there was constipation, aloes and quinine, and, when the bowels were not confined, aloes and sulphate of iron. The action of aloes, as well as of other resin-bearing purgatives, in the condition of anaemia, is promoted by the conjoined use of the bit- ters, quinine, iron, and tonics generally. Two grains of aloes, taken at bedtime, will cause a satisfactory evacuation on the following day. Combination with soap, as in the official pil. aloes, and pil. aloes et asafcetidae, diminishes the drastic, while it increases the efficiency of the purgative, action. It is generally better to give aloes by itself, without combination with other cathartics ; but its purgative effects may be greatly enhanced by administering a saline laxative six or eight hours after the aloes has been taken. A gonorrhoea may, it is said, be cured by the internal use, three times a day, of a pill containing two or three grains of aloes. Catarrh of the uterus has been treated successfully by aloes rectal enemata. The tincture of aloes, diluted to one half or even more, by water, is a CATHARTICS. 643 very effective injection in gonorrhoea after the acute symptoms have subsided. Jalapa. — Jalap.

The latter has been named convolvulin, or jalap- in, and is the more active purgative of the two. Various secondary products of considerable interest are obtained from the resin, but these possess no special importance from the therapeutical point of view. Physiological Actions. — As a cathartic jalap resembles, but it is much more active than, senna. It is apt to produce nausea, and tor- mina and tenesmus invariably accompany its purgative action. It usually operates in from two to four hours, but the rate at which it moves to affect the intestinal canal is not influenced by the amount administered. The stools are soft at first, and afterward liquid. Jalap does not produce haemorrhoids, nor does it cause a tendency to, or increase an existing, menorrhagia. The secretions of the intestinal canal are increased by it, and the recent researches of Rutherford and Yignal have demonstrated that jalapin (convolvulin) excites the flow of bile. The action of jalap appears to be local. It is true that experiments in support of a contrary opinion have been made ; but, in the conclu- sive test of the intra-venous injection of convolvulin, no purgative action has followed (Husemann). Therapy. — The resin of jalap being the active constituent, it should generally be preferred. It has the merit of being almost tasteless, and hence may be given readily to children. Jalap is an efficient cathartic in the beginning of fevers, inflamma- tions, and acute diseases requiring the use of such therapeutic means. Formerly calomel and jalap were much prescribed, but this combina- tion has deservedly fallen into discredit. Occasionally the resin and calomel, in less ponderous doses than formerly given, may be used with advantage as a cathartic : I£ Resinse jalapse, hydrarg. chlor. mit., ext. hyoscyami, aa gr. j. M. Ft. pil. no. j. Sig. : Take at bedtime. As jalap in sufficient quantity causes free watery evacuations, it is a suitable purgative in anasarca and ascites. The most generally ap- proved hydragogue purgative, under these circumstances, is the com- pound jalap-powder. The efficiency of this may be increased by the addition of podophyllum. A teaspoonful of the compound powder, 644 EYACUANTS. taken in the early morning, will usually produce several very copious, watery stools. Increased urinary discharge also is a not unfrequent result of its action. Jalap has the power to cause the expulsion of lumbrici. As a ver- mifuge it is not at all equal to the other approved remedies, but it is certainly useful as an adjunct. For example, santonin at night, and the resin of jalap and calomel on the following morning, is an effective method of expelling these parasites. Jalap is, of course, contraindicated in inflammatory states of the intestinal canal. In overdoses it causes hypercatharsis, and it may excite violent gastro-enteritis and endanger life. With proper atten- tion to the conditions in which it is admissible, and to the dosage, jalap is entirely safe, and is a very certain and efficient cathartic, ^n ex- cellent vehicle for the administration of the resin of jalap is the sirup of rhubarb.

A resinous exudation from the root of Convolvulus scammonia Linne (Nat. Ord. Convolvulacece). (IT. S. P.) Scammonee, Fr. ; Scammonium, Ger. JResina Scammonii. — Resin of scammony. Dose, grs. v — grs. x. Composition. — The activity of scammony, as a cathartic, depends entirely on the resin which it contains. As the crude scammony is much adulterated, the resin is alone worthy of confidence. Actions and Uses. — Scammony corresponds very closely to jalap in the time it requires to cause cathartic action, in the character of the stools produced, and in the kind of irritation which it excites. Scam- mony is somewhat more drastic than jalap. As it has but little taste, and is at the same time very active, the resin is much prescribed by English practitioners as a cathartic for children. It may be given rubbed up with milk, or with sirup of rhubarb. It is adapted to the same class of cases, and to the relief of the same conditions, as jalap. Colocynthis. — Colocynth. The fruit, deprived of its rind, of Citrul- lus colocynthis Schrader (Nat. Ord. Cucurbit acece). (IT. S. P.) Co- loquinte, Fr. ; Ebloquinten, Ger. Extractum Colocynthidis. — Extract of colocynth.

Pilulce Catharticce Compositm. — Compound cathartic pills. (Com- pound extract of colocynth, abstract of jalap, calomel, gamboge.) Dose, 1 — 3 pills. Each pill contains one grain of calomel. Composition. — Colocynth contains a bitter principle {colocynthiri), which is the purgative principle. Colocynthitin is another substance CATHARTICS. 645 contained in the alcoholic extract. It differs from colocynthin in being soluble in ether, and not in water. As colocynthitin is a tasteless crys- talline powder, it is probably devoid of purgative property. Colocyn- thin is a very powerful cathartic. Actions and Uses. — Colocynth is a gastro-intestinal irritant. In moderate doses it hastens the peristaltic movements, and increases the intestinal secretions. Its cathartic operation is usually attended with griping, and the stools are fluid. Violent gastro-enteritis may be pro- duced by a large quantity, and numerous fatal cases have been reported from its incautious or criminal administration. The action of colocynth is not merely local. Applied to the skin of the abdomen, it causes intestinal pain, and more frequent alvine dis- charges. Colocynth is never administered alone, but usually in combination with other purgatives. The compound extract is a safe, effective, and not unpleasant cathartic for the relief of constipation. 1$, Ext. colo- cynthidis comp., 3j ; ext. belladonna?, ext. physostigmatis, aa grs. v. M. Ft. pil. no. x. Sig. : One each night in habitual constipation. The official compound cathartic pill is a most serviceable combination. Instead of calomel the resin of podophyllum may be used in the prepa- ration of this pill, without impairing its utility. In cerebral congestion the preparations of colocynth are used as derivative purgatives. Hypochondriasis and melancholia, when asso- ciated with torpor of the large intestines and fecal accumulations, are benefited by brisk purging with the colocynth preparations, but other drastic purgatives are equally efficient. Colocynth is inadmissible in inflammatory states of the intestinal canal, and is unsafe during the existence of pregnancy. There is a popular notion, which has led to its use in toxic doses, that colocynth may cause abortion. Any quantity which will affect the gravid womb must be sufficient to endanger life. Podophyllum. — May-apple. The rhizoma and rootlets of Podo- phyllum peltatum Linne (Nat. Ord. Berber idaceai) . (IT. S. P.) JResina Podophylli. — Resin of podophyllum. Dose, gr. \ — gr. j.

Dose, gr. \ — g r - J- Extractum Podophylli Fluidum. — Fluid extract of podophyllum. Dose, m, j — 3 ss. Composition. — The medicinal qualities of podophyllum are due to a resin, or to two resinous substances, one soluble in alcohol and ether, and the other soluble in alcohol only. Both possess purgative proper- ties. May-apple-root contains the alkaloid berberine, which, however, 646 EVACUANTS. is not peculiar to podophyllum, being found in berberis, hydrastis, and other plants. Resina podophylli is the preparation entitled " podophylliD " by the eclectic practitioners. Actions and Uses. — The taste of podophyllum, is bitter, with an after-sense of acridity. It increases the intestinal secretions, and is actively cathartic, producing copious and rather watery stools. Its action is similar to, but considerably slower than, that of jalap. From six to ten hours elapse after its administration before cathartic effects are experienced. Taken by itself, it is apt to cause nausea and griping, but in combination with other cathartics, or with belladonna or hyos- cyamus, it operates pleasantly as well as efficiently. The Edinburgh committee, Dr. Bennett, chairman, ascertained, as they supposed, that the resin of podophyllum has no cholagogue action, but the more re- cent as well as the more accurately conducted experiments of Ruther- ford and Vignal have apparently demonstrated that it decidedly in- creases the flow of bile, corresponding in this particular to the other resinous cathartics. Podophyllum-resin is the most generally useful cathartic in cases of constipation, in which the secretions of the glandular apparatus of the intestinal canal, and of the liver, are deficient. Habitual constipa- tion, due to torpor of the muscular layer of the bowel, may, it is said, be removed by the nightly use of a small dose of the resin combined with belladonna. $ Resinae podophylli, grs. vj ; ext. belladonnae, ext. physostigmatis, aa grs. iij. M. Ft. pil. no. xij. Sig. : One pill each night. It is especially in congestion of the portal circulation, in catar- rhal and malarial jaundice, and in ascites, that podophyllum-resin acts most efficiently and serviceably. Haemorrhoids that bleed in conse- quence of stasis in the portal circulation, and that are of recent forma- tion, may sometimes be cured by a brisk podophyllum cathartic. The clinical experience which had shown that the resin of podo- phyllum possessed cholagogue powers, long before the experimental inquiry was instituted to settle the question, led also to a wide gener- alization in the therapeutical uses of this agent. Acting on the liver, it was assumed that, in a manner similar to mercury, it must also pos- sess similar " alterative " powers. It came to be used as the " vege- table calomel," in the diseases in the treatment of which mercury was supposed to be essential. It need hardly be asserted that these specu- lations have no basis, and that podophyllum possesses no property in common with mercury except its power to purge. Leptandra. — Leptandra. The rhizoma and rootlets of Leptandra Virginica Nuttall (Nat. Ord. Scrophulariacem). (II. S. P.) Extr actum Leptandra^. — Extract of leptandra. Dose, gr. ij — gr. x. CATHARTICS. 647 Extractum Leptandrm Fluidum. — Fluid extract of leptandra. Dose, in, v — 3 j. Composition. — A crystallizable principle has been obtained from the root — leptandrin (?). It contains also a resin which, in the impure form at present found in commerce, has a distinctly purgative quality and is known as leptandrin. The dose of this preparation is gr. ij — gr. v. Actions and Uses. — Leptandra is an active cathartic in the recent state. In the form of the fluid extract, or of the so-called leptandrin, it acts mildly, causing somewhat liquid and apparently bilious stools. It is held to be cholagogue, and, according to the rules of analogy, this claim may be well founded, for other cathartics containing resin, as the experiments of Rutherford and Yignal have shown, possess the power to increase the flow of bile. It is applicable to cases of disease of the intestinal canal, attended by constipation, in which the biliary and intestinal secretions are in- sufficient. Iris. — Blue flag. The rhizoma and rootlets of Iris versicolor Linne (Nat. Ord. Iridacem). (IT. S. P.) Extractum Iridis. — Extract of iris. Dose, gr. j — gr. v. Extractum Iridis Fluidum. — Fluid extract of iris. Dose, v\ v -3j. Under the name iridi?i, there is to be found in the shops a "resi- noid," having more or less of the properties of the crude drug. The dose of this preparation is from one to five grains. Actions and Uses. — Iris versicolor has a bitter, nauseous, and rather acrid taste. It is apt to cause severe nausea. The fresh root has actively purgative and diuretic qualities, but these are impaired by age. The fluid extract and the " iridin " are laxative, and are sup- posed to have cholagogue powers. The oleo-resin is prescribed in hepatic and intestinal disorders, and in dropsy. There is much evidence tending to show that this remedy is really serviceable when the stools are clay-colored, and the skin jaundiced, in consequence of duodenal catarrh and obstruction of the biliary ducts. It is said that malarial jaundice may be cured by this drug, and that in bilious remittent fever and in chronic malarial poi- soning it exerts a favorable influence. EuonymuS. — Wahoo. The bark of Euonymus atropurpureus Jac- quin (Nat. Ord. Celastracew). (U. S. P.) Extractum Euonymi. — Extract of enonymus. Dose, gr. j — gr. v. The eclectic preparation (euonymin) consists of the resin and fixed oil, and is prescribed in the dose of a half -grain to five grains. Composition. — An uncrystallizable and intensely bitter principle 648 EVACUANTS. has been isolated (euonymin). It contains also a crystallizable, a yel- low and a brown resin, fixed oil, etc. Actions and Uses. — Euonymus possesses cathartic properties simi- lar to rhubarb, but is much milder, and is an excellent remedy in hepatic and intestinal disorders requiring the use of such an agent. The eclectic preparation (euonymin) is a convenient form in which to procure the cathartic action of euonymus. Rutherford has shown that it is a highly efficient cholagogue. Baptisia. — Wild indigo. The root-bark of Baptisia tinctoria. (Not official.) Preparations corresponding to those of iris and euonymus can be obtained. Extr actum JBaplisice. — Extract of baptisia. Dose, gr. j — gr. x. Baptisin, the resinoid, is much prescribed by eclectic practition- ers. The dose is one to five grains. Actions and Uses. — The taste of baptisia is bitter and somewhat acrid. It increases the secretions of the glandular appendages of the gastro-intestinal mucous membrane. It possesses in large doses emeto- cathartic property, and may indeed excite violent gastro-intestinal in- flammation ; in small doses it is merely laxative. The resinoid baptisin, so called, has been studied by Rutherford, who found it to possess ac- tive cholagogue property. Given to dogs, it distinctly stimulates the hepatic functions and increases the production of bile. It is probable that it deserves to rank among the most efficient of the remedies of this group. It is indicated, therefore, in all the cases in which hepatic stimulants are desirable. HYDKAGOGUE CATHARTICS. Cambogia. — Gamboge. A gum-resin obtained from the Garcinia Hanburii Hooker filius (Nat. Ord. Guttiferw). (U. S. P.) Gomme- gutte, Fr. ; Gummigutt, Ger. Dose, gr. j — grs. v. The only official preparation is the compound cathartic pill, of which gamboge constitutes about a tenth part. Composition. — Gamboge is a mixture of resin and gum, the latter constituting from fifteen to twenty per cent. Actions and Uses. — Gamboge has no taste at first, but, when chewed, an acrid sensation is developed in the mouth. It is irritant to the gastro-intestinal canal, increases secretion of the glands, excites vomiting and intestinal pain, and purges violently, producing copious watery stools. The experiments of Rutherford and Vignal show that gamboge is not an hepatic stimulant, but does cause hydro catharsis. Violent gastro-enteritis is set up by large doses, yet but few fatal cases have been reported. As vomiting soon follows the ingestion of a large dose, this fact may explain the rarity of a fatal result due to its ad- ministration. CATHAKTICS. G49 Gamboge is rarely prescribed alone as a cathartic, owing to the vio- lence and harshness of its operation. Combination with other cathar- tics, as in the compound cathartic pill, greatly modifies its action. As it is a powerful hydragogue cathartic, it is given with advantage in dropsy, when hydrocatharsis is indicated. It is best administered in small doses, at short intervals, rubbed up with sugar or made into a pill with soap. Besides its purgative properties, gamboge is decidedly diuretic. In order to obtain its diuretic effects it must be given in small doses, at short intervals, and vomiting must be avoided. Admin- istered in solution with an alkaline diuretic, its efficiency is much in- creased. Gamboge has also been used as an anthelmintic, but it has no powers in this respect not possessed by other drastic purgatives. Oleum Tiglii. — Croton-oil. A fixed oil expressed from the seeds of Croton tiglium Linne (Nat. Ord. Euphorbiaceoe). (U. S. P.) Huile cle Croton, Fr. ; Crotonol, Ger. Dose, gt. j — gtt. ij. Composition. — It contains glycerides of the fatty acid series— stearic, palmitic, myristic, and lauric acids — and the more volatile acids, acetic, butyric, and valerianic (Fltickiger and Hanbury, Husemann). Genther and Frohlic have discovered a peculiar volatile acid, to which they have applied the name tiglinic acid. By the same chemists the so-called crotonic acid is held to be an artificial product. Schlippe has asserted the discovery of the vesicating principle of croton-oil, but other chemists have failed to find this substance, to which he has as- signed the name of crotonol. The purgative principle of the oil ap- pears to exist in all parts of the Croton tiglium, but it has not yet been isolated. Actions and Uses. — Croton-oil is a transparent or semitransparent viscid liquid, amber-colored, and having a rather rancid smell, and an oily, acrid taste. Applied by friction to the skin, it excites inflamma- tion, and causes an eruption which is at first papular, with rounded summits, and afterward becoming pustular. The eruption is sometimes umbilicated, but is generally rounded. An areola surrounds the pus- tules, and there are considerable heat and burning in the part. The eruption appears in a few hours after the frictions have been practiced, reaches its maximum in about four days, and then declines by abortion of the pustules and by scabbing. In many subjects permanent, small white cicatrices mark the site of the eruption. All subjects are not equally susceptible to the vesicating action of croton-oil. The mucous membrane is violently attacked by croton-oil. In the fauces it causes an intensely acrid sensation, and increases the flow of saliva. A sense of heat, pain, and nausea is produced when the oil is received into the stomach, tormina soon follows, and in an hour or two watery stools are passed with some burning and irritation about the anus. The action of the oil continues during the succeeding twelve 650 EVACUANTS. to twenty-four hours, numerous fluid dejections are passed, and con- siderable debility is the result. When large doses are taken, if not rejected promptly by vomiting, violent hypercatharsis occurs with great prostration and collapse. Fortunately, when an overdose is swallowed, vomiting quickly ensues, and hence very large quantities have been taken without producing a fatal result. The lesions caused by croton-oil are those of gastro-enteritis, but fatal cases have occurred, with all the objective phenomena of choleraic collapse, without any evidences of local inflammation. As croton-oil is still purgative after being deprived of its acrid principle by washing with alcohol, it has been held that the oil be- comes cathartic only by the action of the alkaline juices of the duo- denum. [Numerous instances have been reported, and some have fallen under the author's observation, in which croton-oil applied to the integument has produced diarrhoea. It must, therefore, act by absorp- tion into the blood. In some cases, without causing purging, croton- oil affects the nervous system in a peculiar manner. Thus restless- ness, palpitation of the heart, headache, giddiness, confusion of ideas, etc., have occurred under these circumstances (Husemann). Rohrig found that croton-oil stimulated the hepatic function, and increased the flow of bile. Radziejewski found peptones, bile, gly- cogen, leucin, and tyrosin, in the stools. Rutherford and Yignal have since shown that croton-oil, although it causes great vascular dilatation of the vessels of the intestinal mucous membrane, can not be regarded as a cholagogue. The principal effect of croton-oil, for which it is administered in medical practice, is that of a hydragogue cathartic. It is, therefore, used in dropsies when it is desired to procure free, watery evacuations. It is inadmissible when there is much debility, or when an irritable or inflammatory state of the intestinal mucous membrane exists. Notwithstanding its great activity, croton-oil is an easily-managed cathartic for ordinary purposes. It is the most efficient purgative when there is simple impaction, without inflammatory symptoms. The con- stipat ion from lead may be overcome by it, when less powerful purga- tives will fail. It is the most appropriate of cathartics, when these agents are indicated as revulsives in cerebral congestion. Croton-oil, by increasing the vascular dilatation in the intestines, lowers the intra- cranial blood-pressure. Per contra, it is harmful when a state of cere- bral anaemia exists. Croton-oil has been used successfully against tcenia, but it has no special vermifuge property. The smallness of the dose required renders croton-oil a very useful purgative in the maladies of children and of the insane. When the patient is unable to swallow from insensibility or paralysis, a drop or two placed on the tongue will act efficiently. It may be given to chil- CATHARTICS. 651 dren, rubbed up with sugar of milk. As washing with alcohol removes the acridity, and does not impair the purgative property, a preparation so treated will be best for administration to children.

Nausea and vomiting, profuse, watery stools, and great weakness and prostration, are produced by a considerable dose of elaterium. The vomited matters and stools have an appearance and composition similar to the "rice-water " discharges of cholera. On animals elaterium acts somewhat differently. Without causing purg- ing, it affects the nervous system, producing irregular respiration, hebetude, convulsions, and death (Kohler). The gastro - intestinal action is doubtless local, and the result of the immediate impression made by the agent in its passage down the intestinal canal. Ac- cording to Kohler, the presence of bile is necessary to the action of elaterium. The chief use of elaterium is to procure free watery evacuations in ascites, general dropsy, urcemia, and to act as a revulsive in cerebral disorders. It must be used with caution in debilitated subjects. Gas- trointestinal irritation, or inflammation, contraindicates its use. The 652 EYACUANTS. depression which its operation induces must be counteracted by stimu- lants and proper aliment. Authorities referred to : Anstie, Dr. F. E.

Enemata. — An enema is a rectal injection. The capacity of the rectum, it need hardly be stated, varies with the age of the individual. For an infant, half an ounce to an ounce ; for a child of two to five years, two to six ounces ; for five to fifteen years, six ounces to a pint; for an adult, a pint to a quart of fluid may be considered as an ap- proximation to the capacity of the rectum at these ages respectively. Habitual use of injections no doubt increases the tolerance, as also the capacity of the rectum. Injections may consist of water — cold, tepid, warm, or hot ; of medicated solutions — emollient, anodyne, laxative, cathartic, or anthel- mintic. Under this head are to be considered only enemata adminis- tered with the view to cause an evacuation from the intestinal canal. Enemata act either by a reflex irritation or by absorption. When a cold injection is thrown into the rectum, or this organ is distended, an action is set up for the expulsion of the offending substance, and the muscular fiber of the bowel more or less vigorously contracts according to its functional condition. The quantity, as well as the temperature of the fluid injected, must therefore be taken into consideration, when it is proposed to empty the bowels by a merely reflex irritation. On the other hand, when it is the intention to procure the absorption of the medicated fluid, the quantity injected must be relatively small, and its temperature should, as nearly as possible, be that of the rectum. In order to secure absorption, it is necessary also to regard the laws of diffusion. As the secretions of the rectum are alkaline, it is obvious that acidulated solutions will diffuse into the rectal veins with the CATHARTICS. 653 greatest facility. It is doubtful whether colloidal substances of them- selves are taken up in the rectum. (See Nutrient Enemata, p. 55.) Irrigation of the intestines, or forced injections of a large quantity of water, is a modern expedient of great practical utility. The appa- ratus required for the performance of this operation consists of a rectal tube, a flexible rubber pipe three or four feet in length, and a funnel- shaped vessel to contain the fluid to be injected. The decubitus on either side, the hips being elevated, may be sufficient ; but, to insure gravitation of the fluid to the ileo-ca?cal valve, the female patient should be placed in Sims's position, and the male patient on his hands and knees. The rectal tube should be inserted, and passed up to the sigmoid flexure ; the flexible tube should then be attached. The height to which the reservoir is raised will regulate the hydrostatic pressure, and the flow of fluid through the flexible tube can be lessened or increased at the pleasure of the operator by compression with the fingers. In administering rectal injections the utmost gentleness is requisite, especially when a large amount of fluid is to be introduced. Rude thrusting of the pipe into the rectum may injure the mucous mem- brane, and rapid and forcible dilatation of the bowel will excite an imperious desire to go to stool. Too great pressure, in the process of irrigation, may cause a rupture of the intestine, especially if its coats are softened by disease or penetrated by ulceration. It is possible that sudden and forcible distention of the bowel may produce dan- gerous cardiac syncope in susceptible subjects. The experiments on the cadaver have demonstrated that, although the large intestine may be filled with water, no fluid can be made to pass the ileo-csecal valve. Notwithstanding these experiments, it has been claimed that in the living subject, by the irrigation method, water can be forced through the whole length of the intestine. If these ob- servations are correct, it is probable that a pathological state of the ileo-csecal valve must have existed.

A common domestic enema consists of soap-suds, made somewhat more stimulating to the rectum by the addition of turpentine. Therapy. — A pint of cold water is a good enema for cases of habitual constipation, especially when there are haemorrhoids which 654 EVACUANTS. bleed with every motion. The enema of aloes, in quantity correspond- ing to the age of the subject, is an efficient remedy for the destruction of ascarides vermicular 'es. The purgative enemata above given are employed to act on the large intestine, chiefly by virtue of reflex stimulation, but, in part, ab- sorption of the purgative principle takes place, whence it follows that they may affect the whole canal. They are used, therefore, as cathar- tics, and for the ordinary purposes of these remedies. The purgative enemata are not suitable for habitual use. They excite irritation of the rectum, which may result in ulceration, ischio-rectal abscess, fistula in ano, fissure of the anus, and other serious accidents. Irrigation of the bowel is resorted to for the removal of impacted faices, to overcome intussusception , etc. Cases of intestinal invagination have been very quickly relieved by sudden inflation of the large intestine with carbonic acid. The process consists in the injection of a solution of sodium bicarbonate, followed by a solution of tartaric acid — about one drachm of each to eight ounces of water. The escape of the gas through the sphincter ani must be prevented by forcible pressure upon the anus. Suppositoria Aloes. — (Aloes and cacao-butter.) Each suppository contains about five grains of purified aloes. One of these, introduced into the rectum at night, will generally procure one or two evacua- tions on the following day. It is not good practice to employ such a method of treatment frequently. A piece of hard white soap cut into a conical shape, and of a suit- able size, is frequently used in domestic practice to relieve the consti- pation of infants. The soap suppository thus prepared is carefully introduced into the rectum. The habit of a daily evacuation may be thus induced. A piece of paper rolled into a conical shape, and dipped into oil, may be used instead of the soap suppository. ANTHELMINTICS. Anthelmintics are remedial agents used to cause the expulsion of parasites from the intestinal canal. Vermifuges are remedies which expel worms ; vermicides are remedies which kill as well as expel worms. Some of these agents act mechanically, as mucuna and pow- dered tin ; others are administered in such quantity as to sicken and disable the worms, when their expulsion is easily effected : for ex- ample, pumpkin-seed emulsion. Others again possess narcotic and toxic properties, as turpentine, chenopodium, santonin, etc. Anthelmintics are conveniently divided into those employed against ascarides vermiculares, those employed against ascarides lumbricoides, and those employed against the different varieties of taenia. ANTHELMINTICS. 655 Ascarides vermicidares infest the rectum and large intestine, ex- tending up occasionally as high as the ileo-csecal valve ; in females, they may also spread into the vagina. As they deposit their ova in the folds of the anus, and in the vagina, it is obvious that the parasiti- cide, to be effective, must be applied in these situations. Infusion of quassia, decoction of aloes, and a weak solution of car- bolic acid, are the most frequently-prescribed remedies for the destruc- tion of ascarides. If carbolic acid is used, the strength of the injec- tion for children should not exceed ten grains to the pint, and it should not be retained. Infusion of quassia is at the same time safe and effective ; but, when this injection is used, a solution of carbolic acid should be applied also, by means of a sponge, to the folds of the anus, and, in the case of female children, to the external genitals. If the ascarides extend up into the large intestine beyond the sigmoid flexure, a dose of santonin and calomel should precede the use of the rectal parasiticide. REMEDIES USED FOR THE EXPULSION OF ASCARIDES LUMBRICOIDES. Muctma. — Cowhage. The hairs of the pods of Mucuna pruriens. This remedy is now rarely if ever used. It is administered in the form of electuary, mixed with molasses. A teaspoonful or more of the mixture should be administered fasting, and after the action of a cathartic. When several doses have been taken a brisk purgative should be given. When cowhage is applied to the skin it excites intense itching, in- flammation in the skin, and pustulation. It has been proposed as a counter-irritant, but a more disagreeable one could hardly be conceived. It is very irritant to the intestinal mucous membrane, as it is to the skin, and an action is speedily set up for its expulsion. When by the use of a purgative, and by reason of fasting, intestinal worms are un- covered and exposed to attack, it is held that the mucuna-hairs pierce the parasites and irritate them, so that their stay in the intestine is rendered intolerable. In consequence of the active peristaltic move- ments induced by the cowhage, and by the purgative with which it is followed, the worms are hurried out with the remaining contents, if any, of the intestines. Santonica. — Santonica. The unexpanded flowers of Artemisia ma- ritima, var. Stechmanniana Besser (Nat. Ord. Composite) . (U. S. P.) Semencine, Fr. ; Wurmsamen, Ger. Composition. — Resin, malic acid, essential oil, and a crystallizable principle (santonin). Santoninum. — Santonin. A neutral principle obtained from san- tonica. A colorless substance, crystallizing in shining, flattened prisms, 656 EVACUANTS. without smell, and nearly tasteless when first put into the mouth, and afterward bitter. It is not altered by the air, but becomes yellow on exposure to light. Nearly insoluble in cold water, it is dissolved by two hundred and fifty parts of boiling water. It is soluble in forty- three parts of cold, or in three parts of boiling alcohol, and in seventy- five parts of ether. Dose, gr. ss — grs. v, according to age. Trochisci Santonini. — Troches of santonin. (Not official.) (San- tonin, 1 ss ; with sugar, tragacanth, orange-flower water, to form four hundred and eighty troches.) Each troche contains a half-grain of santonin. Antagonists and Incompatibles. — We do not possess any satis- factory data in regard to the physiological antagonists of santonin. When a poisonous dose has been taken the stomach should be emptied, and the systemic effects should be treated symptomatically. Synergists. — Therapeutically the action of santonin is aided by cathartics, especially by calomel. Physiological Actions. — In ordinary medicinal doses as used for the expulsion of lumbrici, santonin causes no sensible intestinal dis- turbance. In considerable doses nausea and vomiting are produced, and are followed by colic and diarrhoea. Santonin enters the blood, probably, in combination with soda, for, although it has no acid prop- erties, it has the power to form such combinations. Santonin, ac- cording to Hesse (Fltickiger and Hanbury), is the anhydride of a crystallizable acid, which, when heated, is resolved into santonin and water. Vision is affected in a remarkable manner. Usually all objects appear as if viewed through yellow glass ; but other colors sometimes appear, as green, blue, or even red ( Gelbsehen, Rose). The chroma- topsia is probably due, according to Rose, to the solution of santonin in the alkaline serum, and its action on the perceptive centers (vol. xviii, page 26). In passing out with the urine santonin imparts a yel- lowish, and, when the amount is large, a reddish-purple, hue to this fluid. In toxic doses santonin produces very decided cerebral effects : trembling, vertigo, convulsive movements, tetanoid cramps, stupor, cold sweats, dilated pupils, insensibility, etc. Therapy. — Cures of amaurosis have been reported from the use of santonin, but we possess no exact indications for its administration. It is, probably, effective only in functional derangement. The chief use of this remedy is for the expulsion of ascarides lumbricoides. It is the most effective and pleasant remedy which can be employed for this purpose. A convenient form for administration is the troche, or it may be prescribed in a powder with calomel. The following is a successful plan of using this parasiticide : A laxative in the morning, fasting through the day, a dose of santonin and calomel at bedtime, a senna-draught on the following morning.

Spigelia. — Pink-root. The rhizoma and rootlets of Spigelia Mari- landica Linne (Nat. Ord. Loganiacew). (U. S. P.) Extractum Spigelian Fluidum. — Fluid extract of spigelia. Dose, 3j— Iss. Composition. — A bitter, uncrystallizable principle (spigelin ?), vol- atile oil, tannic and gallic acid. Actions and Uses. — In moderate doses spigelia produces a sensa- tion of warmth at the epigastrium, stimulates the intestinal movements, accelerates the action of the heart, and promotes the cutaneous trans- piration. In large doses it causes cerebral effects, vertigo, dimness of vision, dilated pupils, convulsions, and insensibility. Many of the serious symptoms supposed to have been produced by it in certain cases were probably really due to pre-existing cerebral lesions. Cases of basilar meningitis, for example, have not unfrequently been con- founded with " worm-fever." Any vermifuge, given under these cir- cumstances, might seem to have caused the head-symptoms which are characteristic of the brain-lesions. Spigelia is used only as a vermifuge, and against the round worm, for the expulsion of which it has proved to be very efficient. A low diet and a brisk cathartic should precede the use of this remedy. The best form for administration is the fluid extract of senna and spigelia. Authorities referred to : Porcher, Dr. F. P. Resources of the Southern Fields and Forests. Stille, Dr. Alfred. Therapeutics and Materia Medica. Chenopodium. — Worm-seed. The fruit of Chenopodium anthelmin- ticum Gray (Nat. Ord. Chenopodiacece). (IT. S. P.) Oleum Chenopodii. — Oil of worm-seed. Dose, gtt. v — gtt. xv. Actions and Uses. — The oil of worm-seed is the only preparation of the plant now used, and this is rarely employed, in consequence of its very disagreeable and characteristic odor and taste. It excites a sensation of warmth at the epigastrium, increases the action of the heart, and promotes cutaneous, bronchial, and renal secretions. It is a diffusible stimulant, and as such may be given with advantage in hys- teria and chorea, as a carminative in flatulence, and as an antiperiodic in inter mittents. The only use of worm-seed is as a remedy for as- carides lumbricoides. It is one of the most efficient of the class. It 42 658 EVACUANTS. should be given three times a day for two days, and followed by a brisk cathartic. An excellent combination for the expulsion of the round worm is ten drops of worm-seed oil, and a teaspoonful of fluid extract of senna and spigelia. It may also be administered in castor-oil. REMEDIES USED AGAINST T.ENLE. The success of tseniafuges depends largely upon the preliminary treatment. The parasite is imbedded in mucus, its hooklets fixed in the mucous membrane. The medicament which is administered for its expulsion must come in contact with the scolex. To dislodge a quan- tity, however large, of the segments (strobila), although temporary relief may follow, will not be permanently curative. The head of the parasite must be expelled. Before using the tseniaf uge the contents of the intestinal canal must be thoroughly evacuated. Two days of fasting, some milk and bread only being taken, must precede the treatment. Aspidium. — Male fern. The rhizoma of Aspidium filix mas Swartz, and of Aspidium marginale Willdenow (Nat. Ord. Filices). (U. S. P.) Fougere male, Fr.; Wurmfarnwurzel, Ger. Oleo-resina Aspidii. — Oleo-resin of fern. Dose, 3 ss — 3 ij. Composition. — A green, fatty oil, volatile oil, resin, tannin, etc. The ethereal extract deposits a granular, crystalline substance (iilicic acid), on which the medicinal activity of the drug appears to depend. Actions and Uses. — The oleo-resin of filix mas is a very efficient remedy for tape-worm, especially the unarmed variety ; but, if suitable precautions be taken to insure success, it is quite a certain remedy for the armed tsenia. The method of Trousseaux and Pidoux is as efficient as any (vol. ii, page 1040). On the first day, a strictly milk diet ; on the morning of the second day, four grammes (about 3 j) of the oleo- resin in four doses, with an interval of a quarter of an hour between each ; on the third day, the same quantity at the same intervals, fol- lowed by fifty grammes of the sirup of ether, and, a half -hour later, an emulsion containing three drops of croton-oil. Kuchenmeister gives a number of methods, and Cobbold favors the employment of male fern in certain cases. Granatum. — Pomegranate. The bark of the root of JPunica gra- natum Linne (Nat. Ord. Granitacece). (U. S. P.) £corce de racine de grenadier, Fr. ; Granatwurzelrinde, Ger. Composition. — Pomegranate-bark contains a principle — pelleterine — on which its activity depends. The tannate, an efficient tseniafuge, can be given in doses of five grains to one scruple. Actions and Uses. — The rind of the fresh root only should be used. ANTHELMINTICS. 659 The best preparation is the decoction, prepared by boiling gently two ounces of the bark in a quart of water down to a pint. Of this decoc- tion a wineglassful may be given every hour until all is taken. It should be preceded by a brisk purgative, and should be taken fasting. It produces more or less nausea, borborygmi, intestinal pain, and usu- ally purges. If a purgative effect is not caused by it, a brisk cathartic should follow. In the author's experience, this is a very certain and efficient tseniafuge. Tauret's preparation of uupurified pelleterine, in solution, has acted very efficiently in some cases. Brayera. — Kousso. The female inflorescence of Brayera anthel- mintica Kunth (Nat. Ord. Rosacea). (U. S. P.) Br ay ere anthelmin- thique, Fr. ; Kussobltithen, Ger. Mctractum Brayerce Fluidum. — Fluid extract of brayera. Dose, 3 ij— I j- Infusum Brayerce. — Infusion of brayera (six parts to one hundred of water). Dose, § iv — § viij — Oj, or more. Composition. — Brayera contains an active principle (kosin, or koussin), which crystallizes in rhombic prisms. Kosin appears to be inert of itself, and is active only when combined with the other con- stituents of the drug. Actions and Uses. — Kousso is used solely as an anthelmintic. Opinions vary as to its utility. On the whole, it may be said that the first enthusiasm which attended its introduction into practice has died away. It brings the segments, but rarely expels the head of the para- site. It is necessary to take it in large quantity — half an ounce — mixed with water. It is retained with difficulty, and produces much intestinal distress. When successful, the worm is brought away with- out the action of a purgative. Kamala. — Kamala. The glands and hairs from the capsules of Mallotus Philippinensis Mueller Arg. (Nat. Ord. Euphorbiaceoi). (U.S. P.) Dose, 3j— 3iij. There are no official preparations. A saturated tincture may be given, in the dose of one to three drachms. Actions and Uses. — It is an orange powder. It causes some nausea and griping, usually, but it may operate without producing any un- pleasant sensations. It acts as a purgative, and causes the expulsion of the worm. If one dose is insufficient, its administration should be continued every three hours until five or six doses have been taken. Kamala is effective not only against tape-worm, but also against lum- brici and ascarides vermiculares. Pepo. — Pumpkin-seed. The seed of Cucurbito pepo Linne (Nat. Ord. Cucurbitacem). (U. S. P.) Actions and Uses. — This is one of the most efficient remedies which 660 EVACUANTS. we possess against taenia. Two ounces of the fresh seed are pounded in a mortar, with a half -pint of water, until the husks are loosened and an emulsion is made. The mixture is then strained, and the whole amount is taken fasting ; but Squibb maintains that all should be taken, husks included. If an action of the bowels does not take place in two hours, the emulsion should be followed by castor-oil. If success is not attained, the dose may be repeated each morning until the parasite is produced. Numerous cases of successful use of pumpkin-seed emul- sion have been reported. The expressed oil, which is bland and unirritating, like almond-oil, may be used as a substitute for the seeds. It should be given in the dose of a half -ounce, two or more times, and after several hours fol- lowed by castor-oil. The rules already given, in regard to preliminary treatment, should also be followed. Authorities referred to : Cobbold, T. Spencer. On Parasites.

They stimulate the kidneys to increased activity, and excite the functions of the pelvic viscera. In excessive quantity, or long continued, they may set up inflammation of the kidney, pro- duce strangury and bloody urine, excite uterine contractions, and stimu- late to an unnatural degree the sexual propensities. They contain an essential oil, or principle, which makes its exit by the urinary passages and excites local irritation by direct contact. Terebinthina. — Turpentine.

(Resin ce- rate, sixty-five parts ; oil of turpentine, thirty -five parts.) UMNO-GENITALS. 661 Antagonists and Incompatibles. — All remedies increasing waste, and the vasomotor depressants, counterbalance the therapeutical ac- tions of turpentine. In cases of poisoning the stomach should be promptly emptied, and anodynes and demulcents should be adminis- tered. Elimination should be favored, and the toxic symptoms treated according to the systemic indications. Ozonized oil of turpentine is an antidote to phosphorus, preventing the formation of phosphoric acid and converting the poison into an insoluble spermaceti-like substance. Turpentine worn in a vial about the neck prevents necrosis of the jaw and steatosis of organs in workmen engaged in manufactures employ- ing phosphorus. Synergists. — The diffusible and alcoholic stimulants favor the action of turpentine. Physiological Actions. — Turpentine-oil is a limpid, colorless fluid, having a strong, peculiar, and diffusive odor, and a hot and pungent taste. It is very slightly soluble in water. The oil exposed to the air absorbs oxygen (ozone), which it retains with great tenacity. Ap- plied to the skin, turpentine causes heat, redness followed by a vesicu- lar eruption, and sometimes by intractable ulcerations. A few drops produce a sense of heat at the epigastrium, and a large dose (medi- cinal) causes intense burning pain, nausea, eructations of the oil, in- testinal irritation and purging (usually). Notwithstanding its slight solubility in water, turpentine diffuses into the blood with facility, and is quickly recognized in the breath, sweat, and urine. The action of the heart and arteries is increased by it, the arterial tension rises, and a general sense of warmth and exhilaration is experienced. In large doses (one or two ounces) vomiting, thirst, and a febrile state, are induced ; the muscular strength is diminished, the power of co-ordina- tion is impaired ; exhilaration of mind, incoherence of ideas, and ram- bling insensibility, follow. In toxic doses there are complete muscular relaxation and profound insensibility with abolition of all reflex move- ments ; the face is flushed or cyanosed, the pupils usually dilated, and the breathing labored and stertorous. All the organs by which tur- pentine is eliminated, especially the kidneys, suffer from extreme irri- tation when large doses have been swallowed. The skin is usually moist, and exhales a turpentine-odor ; the bronchial secretion is in- creased, and convulsive coughing is induced ; the urine is scanty and bloody, and there is violent strangury. The only fatal cases which have been reported have occurred in children (Taylor). From four to six ounces have not destroyed life in adults. As regards its action on the organs of circulation, the author's experiments show that turpentine stimulates the vaso-motor nervous system when administered in moderate doses. A large quantity quickly exhausts the irritability of the sympathetic ganglia, the action of the heart becomes weak, and the arterial tension falls ; the respira- 662 EVACUANTS. tory movements are at first stimulated, but afterward become shallow, and carbonic-acid poisoning supervenes. The brains of animals killed by turpentine smell strongly of it, and hence it may be concluded that it has a direct action on the cells of the cerebral lobes. Turpentine has decided antiseptic power. It arrests fermentation processes, putrefaction, and is very destructive of minute organisms (vibrio, bacteria, etc.). The vapor of turpentine inhaled produces nasal and bronchial irri- tation, frontal headache, and renal irritation, even bloody urine and strangury. On post mortem after turpentine-poisoning, violent gastro-intestinal irritation, ecchymoses of the air-passages, congestion of the lungs, and hyperemia of the kidneys, are noted. Therapy. — Flatulence may be quickly relieved by a few drops (three to five) of turpentine, on a lump of sugar. This remedy is especially indicated in flatulence persisting from a paretic state of the muscular layer of the bowel. There is abundant evidence to prove the curative power of oil of turpentine in chronic intestinal catarrh. It is especially indicated when the tongue is dry and glazed, when there is tympanitic distention of the bowels, and w T hen the alvine discharges consist either of fluid faeces or scybala, mixed with mucus and pale, watery blood. It is best administered in an emulsion, with almond- oil and opium. ^ 01. terebinthini, 3 j ; ol. amygdal. express., § ss ; tinct. opii, 3 i j ; mucil. acacise, 3v; aquae laur.-cerasi, 3 ss. M. Sig. : A teaspoonful every three, four, or six hours. The same remedy, in a similar combination, is very effective in acute dysentery after the sub- sidence of the more acute symptoms. The following is probably the true explanation of its action in these cases : it gives tonicity to the vessels, and to the muscular fiber of the intestines ; arrests the putre- factive and fermentative processes which take place in the vitiated mucus and articles of food, and increases the cutaneous capillary circu- lation, thus relieving congestion of internal organs. Stimulating enemata are made of turpentine, mucilage, oils, etc. These are especially indicated in constipation, and in impaction of the rectum. I£ 01. terebinthini, 3 ij — 3 j ; ol. ricini, | ij ; vitell. ovi unius ; decoct, hordei, § viij — Oj. M. Sig.: As an enema. Such in- jections are frequently used in tympanitic distention of the large intestine, in flatulent colic, in impaction of the caecum, etc. A combination of equal parts of turpentine and ether constitutes the well-known remedy of Durand for the solution and cure of biliary calculi. Notwithstanding the unquestionable utility of this remedy, we can not admit with Durand that its efficacy depends on its solvent power (Trousseau). During the attack of biliary colic this remedy may be administered with a view to its anodyne and antispasmodic effect ; but, as Kohler states, it is by no means equal to morphine and UMNO-GENITALS. 663 chloral hydrate. In the after-treatment, clinical experience is in favor of the occasional administration of Durand's remedy during a course of Vichy or Carlsbad water. Turpentine is one of the most effective remedies which we possess in the treatment of taeniae. Full doses ( § ss — § ij) are required, and the rules for preliminary treatment already laid down (see Anthel- mintics) should be adhered to. Turpentine should be combined with a purgative, in order to insure prompt cathartic effect. If absorption of any considerable part of the turpentine takes place, violent intoxica- tion will follow, and irritation of the kidneys, haematuria, and stran- gury, will be produced in the efforts at elimination. The oleo-resin of filix mas may be combined with turpentine. I> 01. terebinthinae, 5 j ; oleo-resinae filicis, 3 j ; vitell. ovi no. ij ; ol. ricini, f j. M. Sig. : A draught. This is an effective, but by no means an agreeable, mix- ture. An ounce each of turpentine and castor-oil may be administered, as the cathartic, after the use of the decoction of pomegranate. Turpentine being a cardiac stimulant, and an excitant of the capil- lary circulation, is contraindicated in hypertrophy of the heart, and when advanced atheroma of the cerebral arteries may be presumed to exist. It is a serviceable cardiac stimulant when the action of the heart is weak, and the arterial tension low. In the passive haemor- rhages we possess few agents more generally useful. The indications for its use are a condition of debility, relaxation of the vessels, and an impoverished condition of the blood. Transudations on the free mu- cous surfaces — epistaxis, bronchial haemorrhage, haematemesis, intesti- nal haemorrhages, haematuria— when associated with the state of con- stitutional depression defined above, are forms of haemorrhage in which turpentine should be used. ^ 01. terebinthinse, 3 iij ; ext. digitalis fl., 3 j ; mucil. acaciae, 1 ss ; aquae menthae pip., f j. M. Sig. : A teaspoonful every three hours. The hsemorrhagic transudations which take place in purpura, in scorbutus, and allied states, are also arrested by turpentine. It need hardly be stated that active haemorrhage and a condition of plethora contraindicate the use of turpentine. As a stimulant to the vaso-motor nervous system, turpentine is in- dicated in fevers when the action of the heart is feeble, the arterial tension low, and the peripheral circulation languid. Ten drops in an emulsion is a suitable form, and every two hours is a proper interval for its administration in this condition of things. According to G. B. Wood, a dry tongue, peeling off in flakes, leaving a glazed surface be- neath, is a special indication for the use of turpentine in fevers. The intestinal haemorrhage of typhoid may be restrained by turpentine. Clinical experience is in favor of the use of turpentine in puerperal fever and in yellow fever. The indications for its employment in these maladies are just the same as those mentioned above in typhoid. Cardiac weakness, depression of the vaso-motor nervous system, a dis- 664 EVACUANTS. solved state of the blood, are the conditions requiring turpentine. Tympanitic distention of the abdomen is an additional indication in puerperal fever. Similarly, turpentine is used in epidemic dysentery, traumatic erysipelas, hospital gangrene, etc. In these various states, employed with a well-defined conception of its real powers, this remedy is more generally serviceable as a stimulant than alcohol. As respects the dosage, in febrile diseases, a rule may be formulated as follows : for the intestinal complications, small doses frequently repeated (ten drops) ; as a stimulant to the vaso-motor nervous system, larger doses (tti x — 3 ss) at somewhat longer intervals. In the article on " Phosphorus " attention has been called to the utility of turpentine in poisoning by this substance. The physiological effects of turpentine indicate its utility in certain disorders of the nervous system. As an enema, turpentine has been used for its derivative effect in insolation or sunstroke (Levick, Wood), and in cerebrospinal meningitis (Hirsch). So accurate an authority as Topinard maintains the utility of this remedy in the cystic compli- cations of posterior spinal sclerosis. Turpentine has long been used successfully in epilepsy, but in those cases only in which the seizures were due to the reflex impression of intestinal parasites (taeniae). Tic- doidoureux and sciatica, when rheumatic in origin, or when produced by fecal accumulations, have been cured by the vigorous use of turpen- tine, but we have now other means of treatment more generally useful and less disagreeable. As turpentine is largely eliminated by the bronchial and renal mu- cous membrane, decided effects are produced at these points. In dif- fusing outward, a change in the tonicity of the vessels, and in the character of the secretions, must necessarily be produced. Clinical experience confirms the deductions of theory. In chronic bronchitis, with profuse expectoration (bronchorrhcea), especially when the expec- torated matters have a fetid odor, turpentine is an excellent remedy (Oppolzer). In gangrene of the lung, although it is not curative, it acts beneficially in diminishing the fetor. In pneumonia and capil- lary bronchitis, when the vital powers are depressed and the peripheral circulation is feeble, turpentine is one of the best stimulants which we can employ. The depression which occurs during the period of crisis in pneumonia, and the condition of purulent infiltration, especially in- dicate the use of this remedy. In the so-called humid asthma, and in emphysema with profuse bronchial catarrh, good results are obtained by the use of turpentine. In these various pulmonary maladies, the ac- tion of turpentine is largely local, as already explained, but it should not be forgotten that the powerful stimulation of the cutaneous circulation which it causes must contribute no small share of the curative action. In hydro-nephrosis and pyo-nephrosis turpentine is used as in bron- chial catarrh, viz., to alter by actual contact the relaxed condition of URINO-GENITALS. 665 the vessels, and the pathological secretions of the mucous membrane. It is, of course, contraindicated during the existence of acute symptoms. Chronic catarrh of the bladder is not unfrequently much improved by the use of this agent. It is most serviceable in those cases resulting from a transference of urethral inflammation, or due to prostatic dis- ease. Incontinence of urine, the result of atony of the muscular layer of the bladder, is sometimes removed by small doses of turpentine. Chronic gonorrhoea, gleet, spermatorrhoea, and prostorrhoea, when the discharges peculiar to these maladies are due to a relaxed condition of the affected parts, are not unfrequently remarkably benefited by mod- erate doses of turpentine. External Uses of Turpentine. — The author long ago pointed out the fact that turpentine is one of the most efficient applications in hospital gangrene. The mortified parts are first removed with the scissors, and the remedy is then applied directly to the affected sur- face, by means of a piece of cotton cloth saturated with it. Fetor is removed and sloughing is arrested, and but little pain attends the application. Turpentine-stupes are much employed as a local and external means of treating internal inflammations. A piece of spongio-piline, or of flannel, large enough to cover the affected part, is first moistened with hot water, and then a few drops of turpentine (five to ten drops only) are sprinkled on it. As very severe smarting, inflammation, and vesi- cation of the skin may occur from the application, and be experienced, indeed, some time subsequently to the removal of the stupe, care must be used not to continue it too long. Liniment of turpentine is a convenient counter-irritant in cases of myalgia, superficial neuralgia, lumbago, etc. An excellent counter- irritant application is made by mixing equal parts of oil of turpentine, acetic acid, and liniment of camphor (Stille). The most successful treatment of severe burns is by the plan of Kentish, which consists in first washing the injured surface with turpentine, and then applying an ointment made by mixing basilicon-ointment with turpentine. Ery- sipelas has been treated by the same measures by Meigs, and the same applications are generally in use in chilblains. Inhalations of turpentine-vapor, or atomized turpentine, is an effi- cient means of local treatment in chronic laryngeal and bronchial af- fections. As a matter of curious therapeutics, it may be mentioned that gonorrhoea has been successfully treated by requiring the patient to inhale the vapor of turpentine.

It is an oleo-resin, the volatile oil con- stituting from forty to sixty per cent. The oil of copaiba is isomeric with the oil of turpentine, but it differs in some of its physical prop- erties from the latter. The resin has an acid reaction, and has been entitled copaivic acid. Actions and Uses. — Copaiba has a nauseous, bitter, and very dis- agreeable taste. When taken into the stomach it causes some heat, and offensive eructations, tasting of the balsam, occur. Indigestion, heaviness at the epigastrium, anorexia, are frequently produced by it, and diarrhoea is an occasional result of its use. It is, therefore, a gas- trointestinal irritant. Both the oil and the resin diffuse into the blood. The various excretions, the sweat, the bronchial mucus, the urine, ac- quire a peculiar and rather a fragrant odor from its presence. This odor is especially observable in the urine, and in this secretion the resin may be discovered also by the addition of nitric acid, which causes a precipitate. At the points of elimination more or less irritation is pro- duced, and, as a result of the irritation, increased secretion ; hence co- 2^aiba is said to be diaphoretic, diuretic, and expectorant. Very serious injury may be done to the gastro-intestinal canal, and to the kidneys, by the use of this agent in large doses. The author has known gastro- intestinal catarrh to persist many months after a course of copaiba, and he has reason to believe that desquamative nephritis and fibroid kid- ney have resulted from its free administration for a lengthened period. While small doses of balsam will increase the gross amount of urine and of the solid contents, large doses will actually cause a diminution in the amount both of water and solids by setting up renal irritation. Although, during a course of balsam, nitric acid causes a precipitation URINO-GEXITALS. 667 of the resin, which is dissolved on the addition of alcohol, the author has, in several instances at least, detected albumen in the urine of those taking this remedy. Copaiba is contraindicated when a condition of gastro-intestinal ir- ritation and hyperemia of the kidneys exist. Gonorrhoea is the disease to which copaiba is most especially adapted. Its administration should not be begun, however, until after the acuter symptoms have subsided. As the action of the remedy is local or direct, acute symptoms are rather aggravated by it. Combina- tion with liquor potassae promotes its curative action by diminishing the acidity, and hence the irritation produced by the urine. Combina- tion with agents acting synergistically, as oils of cubebs and sandal- wood, is also desirable- The following formulae exemplify these thera- peutical facts : ^ Copaibae, pulv. cubebae, aa J ij ; aluminis, § j ; opii, gr. v.

In chronic catarrh of the bladder, copaiba is useful by virtue of the local action which it has upon the mucous membrane. Its nauseous taste and the gastric and renal irritation produced by it are serious objections to its use in a malady which requires the persistent and long-continued application of remedies in order to even moderate its symptoms. For acute bronchitis after the subsidence of the fever, for chronic bronchitis with profuse secretion, for bronchorrhoea (dilated bronchi), copaiba is the most generally serviceable expectorant. Unfortunately, it is so disagreeable that it is difficult to overcome the repugnance of patients. Even when administered in capsules, or in pill-form with magnesia, the nauseous eructations excite disgust. ^ Copaibae, bal- sam, tolutan., pulv. acaciae, aa I ss ; acid, sulphur, aromat., 3 ss ; aquae destil., I vj.

This is not in conse- quence of a selective action on the skin, but is the result merely of the gastro-intestinal disturbance. Influenced, probably, by this fact that an eruption may be caused by copaiba, this agent has been proposed 668 EVACUANTS. as a remedy in certain cutaneous diseases — in those characterized by torpor of the peripheral circulation.

Trochisci Cubebm. — Troches of cubeb. Composition. — Cubeb contains a volatile oil which varies in pro- portion from six to fifteen per cent. It is polymeric with oil of turpen- tine. This volatile oil separates in the cold into two distinct substances — a camphoraceous substance (cubebene), and a liquid portion {cubeben). Besides these, a neutral crystallizable principle (cubebin) has been iso- lated. Cubeb also contains a resin, divisible into two distinct sub- stances, an indifferent portion and an acid {cubebic acid). The thera- peutical properties of the drug reside chiefly, if not exclusively, in the oil and resin, hence the oleo-resin is an efficient preparation. Actions and Uses. — The taste of cubeb is aromatic, pungent, and somewhat camphoraceous. In the stomach it excites a sensation of warmth, and, in moderate doses, promotes the appetite and the diges- tive capacity. In considerable doses it is laxative, and produces a feel- ing of heat and irritation about the rectum. Ingested in a large quan- tity, cubeb sets up a gastro-intestinal catarrh, and may even cause acute inflammatory symptoms. The active principles diffuse into the blood. The action of the heart and vascular system is increased by cubeb, the surface becomes warm and perspiring under its use, and the bronchial and urinary secretions are more abundant. The odor of cubeb is im- parted to the breath and to the* urine, and the resin may be precipi- tated from the urine by the addition of nitric acid. As explained in the previous article (Copaiba), the resin precipitated by nitric acid re- sembles albumen, but differs from the latter substance in being soluble in alcohol. URINO-GENITALS. 669 Cubeb stimulates the venereal appetite in man, and promotes the catamenial flux in women. Finely-powdered cubeb is an efficient local application in chronic nasal catarrh. It is blown into the nares by an insufflator. It gives considerable relief also in hay-asthma, when there is no fever, and the secretion of the nasal mucous membrane is profuse and watery. Pow- dered cubeb is useful as a topical application when the mucous mem- brane of the fauces is relaxed, or the seat of chronic inflammation {fol- licular pharyngitis). The official cubeb-troches are employed by sing- ers and public readers, to maintain the tonicity of the mucous mem- brane and to prevent or relieve hoarseness. Cubeb may also be used, in small doses, to promote secretion and increase digestion in cases of atonic dyspepsia. Chronic catarrh of the colon and rectum, with a relaxed condition of the mucous membrane and of the inferior hemorrhoidal vessels, may be removed by cubeb. Sometimes these cases take the form of a mucous dysentery. The most important application of cubeb is in the treatment of gonorrhoea. Unlike copaiba, it may be administered with good effect during the acute stage. The best results are obtained from a mixture of the two agents. Catarrh of the bladder, prostorrhcea, spermator- rhoea, are maladies in which cubeb may be employed with more or less advantage. When the sexual appetite is weak, and the erections fee- ble, cubeb will sometimes, if the troubles are functional, remove them. Irritability of the bladder, nervous or functional in character, espe- cially as it occurs in women, is generally relieved by cubeb ; but can- tharides is a more efficient remedy for this troublesome affection. In chronic bronchial affections, with profuse expectoration, cubeb has a remedial effect similar to that possessed by copaiba, and is useful under the same conditions. Piper. — Black pepper. The unripe berries of Piper nigrum Linne (Nat. Ord. Piperacem). (IT. S. P.) Poivre noir, Fr. ; Schwarzer Pfeffer, Ger. Composition. — Pepper contains a resin and an essential oil, and a neutral crystallizable principle (piperbi). Oleo-resina Piperis. — Oleo-resin of black pepper.

The fruit of Capsicum fastig latum Blurae (Nat. Ord. Solanacece). (U. S. P.) Poivre tflnde, Fr. ; Spanischer Pfeffer, Ger.

Oleo-resina Capsici. — Oleo-resin of capsicum. Dose, ttx j — ti], v. Tinctura Capsici. — Tincture of capsicum. Dose, Tit x — 3 j. Actions and Uses. — Notwithstanding black and red pepper belong to different orders, they are closely related therapeutically and in their physiological actions. They may with propriety be considered together. When applied to the skin, pepper excites redness, heat, and super- ficial inflammation. Red pepper, if in contact with the skin a suffi- cient length of time, will produce vesication. It also causes great irri- tation of the mucous membrane. It has a hot, pungent, and rather acrid taste, and increases the flow of saliva. In the stomach a sensa- tion of warmth is produced by it, the secretions are more abundant, digestion is more active, and the appetite is promoted. In an exces- sive quantity gastritis may be produced. The intestinal secretions are no doubt increased, and the alvine evacuations rendered more easy and copious. The action of the heart and arteries is increased by pepper, a sub- jective sensation of warmth is experienced throughout the system, and cutaneous transpiration becomes more abundant. Elimination takes place chiefly through the kidneys. The flow of urine is increased, micturition is more frequent, and more or less vesical tenesmus occurs. Decided aphrodisiac effects are produced by red pepper. The tincture of capsicum may be usefully employed as a stomachic in atonic dyspepsia. It is especially indicated in the dyspepsia of chronic alcoholism, when there are present trembling and insomnia. Flatulent colic may be relieved by capsicum, especially when this dis- order occurs in hysterical subjects. The author has seen excellent re- sults from the use of this remedy in the dyspepsia and flatulence of hypochondriacal subjects, and of women at the climacteric period. Capsicum is an excellent addition to beef -tea when this aliment is administered in fevers, and other low conditions of the system. The tincture may be employed under the same circumstances as a cardiac stimulant. Piperin has been used in cholera as a stimulant, local and general, and in low conditions of the system from any cause except gastro-intestinal inflammation. At one time it was much prescribed in malarial fevers as an adjunct to quinine chiefly, and antiperiodic powers were ascribed to it ; but such views are no longer entertained. URINO-GENITALS. 671 The evidence is conclusive that capsicum quiets restlessness and induces sleep in delirium tremens. It may be administered mixed with beef -tea or other animal broths, or thirty grains made into a bolus, with sirup or honey, may be given. As capsicum belongs to the fam- ily Solanacem, and as Felletar discovered in it a volatile alkaloid, a ra- tional explanation is afforded of its action on the cerebrum. Accord- ing to Ringer, the tincture of capsicum is the best substitute for the stimulant when an attempt is made to break the alcohol-habit. It is also very serviceable in the treatment of the opium-habit. The good effect of the remedy in these cases is in part due to its action as a stomachic stimulant, and partly, doubtless, to its cerebral effects. The oleo-resins of black and red pepper have been used with good results in the treatment of intermittent fever. They are useful chiefly as adjuvants to more efficient remedies. Capsicum is contraindicated in all acute affections of the genito- urinary apparatus. In chronic parenchymatous nephritis it checks the waste of albumen. In chronic pyelitis, chronic cystitis, and prostor- rhoea, it has a beneficial effect ; but, although similar in action to, it is less efficient than, cubeb. Excellent results are often obtained from it in functional impotence, and in spermatorrhoea from deficient tone. In these genito-urinary maladies, the oleo-resin is the best preparation for administration. 3 Oleo-resinse capsici, 3] ; ergotin (aq. ext.), 3 ij. M. Ft. pil. no. xx. Sig. : One three times a day. A capsicum-plaster is a mild counter-irritant. The infusion is em- ployed as a gargle in tonsillitis, diphtheria, and scarlet fever. As it is a very irritating application, its use should be restricted to cases char- acterized by a low grade of action. Junipems. — Juniper. The fruit of Juniperus communis Linne (Nat. Ord.

(Oil of juniper, 3 parts ; alcohol, 97 parts.) Dose, 3 j — 1 j. Composition. — Juniper contains a volatile oil, upon which its me- dicinal effects chiefly depend. A non-cry stallizable principle (juni- perine) exists in the berries in very small quantity. It contains also formic, acetic, and malic acids. Actions and Uses. — Juniper increases the appetite and digestion, 672 EVACUANTS. but in overdoses will disorder the stomach. The volatile oil diffuses into the blood with facility. Increased action of the heart and of the arteries, a subjective sensation of warmth, diaphoresis, and diuresis, are produced by it. The oil is eliminated by the kidneys chiefly, and imparts an odor of violets to the urine. It powerfully stimulates the renal functions, and in large doses causes strangury and bloody urine. It may set up a high degree of irritation of the kidneys, leading to suppression and uraemic intoxication. In common with the other remedies of this group, juniper excites the venereal appetite; in large doses may cause priapism, and in women promotes the menstrual flow. The principal use of juniper is as a diuretic. It is contraindicated in acute affections of the kidneys. It is largely employed as a diuretic in cardiac and renal dropsy. The infusion is an excellent vehicle for the exhibition of saline diuretics in these affections. The oil of juniper acts similarly to, and is indicated under the same conditions as, tur- pentine in chronic pyelitis, chronic cystitis, gleet, prostorrhcea, etc. Diuretic effects may be obtained by inhalation of the vapor of the oil. For this purpose a few drops may be put into hot water, and the vapor be inhaled. The empyreumatic oil of juniper (oleum cadinum), obtained by de- structive distillation from Juniperus oxycedrus, is a thick, black liquid, similar in appearance to and smelling like common tar. It is much employed as a local application in chronic eczema, impetigo, ichthyosis, psoriasis, acne rosacea, etc. It is usually combined with German soft- soap. 3 Alcoholis, saponis mollis, ol. cadini, aa § j ; ol. lavendula?, 3 jss.

Canada erigeron is the more active, and contains a much larger proportion of volatile oil. The actions and uses of the oil are the same as the oil of turpentine, but the latter is the more efficient remedy. The oil of Canada erigeron has a local reputation in Philadelphia as an haemostatic agent. It is said to be effective in menorrhagia, and cases of intestinal haemorrhage arrested by it have been reported. It is adapted only to the treatment of passive haemorrhages, and is probably less curative than turpentine in these cases. UMNO-GENITALS. 673 Buchu. — Buchu.

This volatile oil consists of a crude oil and a camphor — barosma camphor. The latter has a nearly pure peppermint odor. The existence of barosmin, so called, is doubtful. Uva Ursi. — Uva ursi. The leaves of Arctostaphylos uva ursi Sprengel (Nat. Ord. Ericacece). (U. S. P.) Feuilles de busserole, Fr. ; Barentraubenbldtter, Ger. Decoctum Uvce Ursi. — Infusion of uva ursi ( 1 j — Oj).

(U. S. P.) Genet d balais, Fr.; Pfriemen- kraut, Ger. 43 674 EVACUANTS. There are no preparations official in the United States Pharmaco- poeia. A decoction and fluid extract corresponding to those above mentioned may be employed. Composition. — Scoparius contains an indifferent or somewhat acid crystallizable principle, scoparin, and an oily, colorless, liquid alkaloid, sparteine. The latter has very decided basic qualities, and agrees with conine and nicotine in being constituted without oxygen. Actions and Uses.— Buchu, uva ursi, pareira, pipsissewa, and sco- parius, form a group of diuretics with properties in common. They are tonic, astringent diuretics. They promote appetite and digestion, and restrain intestinal movements, except pareira, which has rather a laxative action. Their active constituents diffuse into the blood and are eliminated by the kidneys. In passing over the genitc-urinary tract these principles act topically upon the mucous membrane. As a rule they are actively diuretic ; that is, they increase the amount of urinary water. Pipsissewa and scoparius are rather more actively diu- retic than buchu and uva ursi, and hence are more useful in dropsy. By English physicians generally, and notably the late Dr. Pereira, sco- parius is held in much esteem as a remedy for dropsy. It is adapted especially to the treatment of cardiac dropsy, and the general anasarca of chronic parenchymatous nephritis, but is inadmissible in acute af- fections of the kidney. Our indigenous remedy, pipsissewa, may be substituted for scoparius in the treatment of dropsy. Buchu, uva ursi, and pareira, are more particularly useful in chronic pyelitis, catarrh of the bladder, chronic gonorrhoea, etc. ; and of these the most efficient, probably, is buchu. The fluid extract is the most eligible form in which these remedies can be administered. Carota. — Carrot-seed. The fruit of Daucus carota. The wild car- rot. (Pharm. 70.) The seeds of carrot have a hot, pungent, and bitter taste, due to a volatile oil which they contain, and to which their medicinal activity is due. As they impart their virtues to water, an infusion of the seeds is an eligible form in which to administer the remedy. Carrot-seeds act similarly to juniper, and produce diuresis, augment the menstrual flux, and cause aphrodisiac effects in the male. Taraxacum. — Dandelion. The root, gathered in the autumn, of Ta- raxacum dens-leonis Desfontaines (Nat. Ord. Compositce). (U. S. P.) Pissenlit, Fr. ; Ldwenzahnwurzel, Ger. Extr actum Taraxaci. — Extract of taraxacum.

Nothing is definitely known as to the action of these substances. Actions and Uses. — Taraxacum possesses the properties of a sim- ple bitter, in that it promotes the appetite and digestion. It has been long held, both popularly and professionally, to possess the power to promote the flow of bile. Recent investigations have demonstrated the inaccuracy of these opinions. It is a mild laxative, and as such, doubtless, may cause by reflex stimulation an emptying of the gall- bladder. It is a diuretic, although not a very active one. It is still prescribed as a laxative in catarrhal jaundice, in ascites from hepatic disease, and in dyspepsia and indigestion associated with torpor of the liver. By German physicians, muriate of ammonia and dandelion are frequently associated together in the treatment of the affections above named. Taraxacum is occasionally used as a diuretic in dropsy, but its utility is very limited. The fluid extract of taraxacum is a good vehicle for the administra- tion of such remedies as the muriate of ammonia and quinine, the taste of which it somewhat covers. Scilla. — Squill. The bulb of Urginea scilla Steinheil (Nat. Ord. Liliacecv). (IT. S. P.) Ognon marin, Fr. ; Meerziciebel, Ger. Acetum Scillce. — Vinegar of squill ( 3 iv — Oij.) Dose, in, xx — 3 j.

This is a very active preparation, due chiefly to the tartar-emetic. Extractum Scilla} Fluidum. — Fluid extract of squill. Dose, t\[ j — ttj, v. Tinctura Scillce. — Tincture of squill. Dose, ttj, v — 3 ss. Composition. — The important constituent of squill is an acrid, bit- ter principle, scillitin, or skulein — which has not yet been isolated. According to Schroff, scillitin is a glucoside, and the active principle is an acrid, non-volatile substance (Fliickiger and Hanbury). Actions and Uses. — The taste of squill is bitter and somewhat acrid. It is an irritant to the mucous membrane, and excites nausea, vomiting, and purging, when introduced into the stomach in a suffi- cient dose. Very violent gastro-enteritis may be produced by its incautious administration in large doses. A state of hyperemia or inflammation of the gastro-intestinal mucous membrane, therefore, contraindicates its use. The active constituents of squill diffuse into the blood. Its sys- temic effects are produced by application to the external integument. 676 EVACUANTS. Paralysis and convulsions are induced in warm-blooded animals by toxic doses ; and similar cerebral symptoms occur in man, in addition to the phenomena which usually attend the action of an irritant poison. In ordinary medicinal doses squill increases the bronchial mucus and facilitates expectoration. In toxic doses rapid breathing has usually occurred. It is highly probable that a portion of the active constituents of squill is eliminated by the broncho-pulmonary mucous membrane. Squill stimulates the functions of the kidneys and increases the urinary discharge when used in medicinal doses, but in excessive quantity it excites violent inflammation, with strangury and bloody urine. Suppression of urine may be a result of its irritating action on the kidneys. The use of squill is confined to its expectorant and diuretic effects. The acetum and syrupus scillce enter into the composition of expec- torant mixtures employed in the treatment of catarrh of the bronchial tubes, after the subsidence of acute symptoms, and the chronic forms of the disease. Squill is more particularly indicated when the sputa are tenacious, and are coughed up with difficulty. Ipecacuanha is ad- vantageously combined with it in the more recent cases. $ Acet. scilla?, § ss ; extract, ipecac, fluid., 3 ss ; tinct. opii deod., 3 j ; syrup, tolutan., 3 x. M.

In dropsy caused by any of the chronic dis- eases of the kidneys, squill must be used with caution. As a diuretic this remedy is more especially useful in cardiac dropsy.

URINO-GENITALS. < 677 Petroselinum. — Parsley-root. The root of Petroselinum sativum. (Pharm. 70.) (Not official.) Composition. — The most important constituent of parsley is apiol, an oily, non-volatile, yellowish liquid, having a distinctive odor and an acrid taste. It contains, also, a gelatinous substance, apiine (pectin ?), and a volatile oil. Actions and Uses. — Petroselinum has a hot, pungent taste, with an after acrid sensation. It is somewhat laxative — a property, doubt- less, dependent on the irritation which it produces. It is stimulant in its effects on the circulation, and promotes the cutaneous and bronchial secretions. It is diuretic, by reason of the local irritant action of the principles which are eliminated by the kidneys. Apiol has decided properties, and in its action strongly resembles quinine. It produces headache, tinnitus aurium, vertigo, intoxication, etc. Petroselinum is rarely employed for its diuretic effects. Its use is indicated in dropsy under the same conditions as juniper, squill, and other stimulating diuretics. It may be given in the form of infusion ( 1 j — Oj)> one ^° three ounces at each dose. Apiol is a remedy of considerable value in the treatment of mala- rial diseases, but it is inferior in every respect to quinine. Its use is only justifiable in the treatment of inter 'mittents, and when the preju- dices or idiosyncrasies of the patient forbid the use of quinine. Fif- teen grains should be administered in one dose, or in divided doses, within an hour, in order to procure the maximum effect, and about four hours previous to the paroxysm. The evidence is conclusive that apiol has decided emmenagogue power. It is a stimulant to the uterine system, and therefore is con- traindicated in plethora of these organs, and should not be adminis- tered as an antiperiodic to pregnant women. It is indicated when a state of torpor of the ovaries and uterus exists. The amenorrhoea of anaemia, of functional inactivity, is the form of the malady in which apiol is serviceable. The condition of the blood should be corrected by iron, constipation should be removed by aloetic purgatives, and the apiol, in a considerable dose (fifteen grains), should then be adminis- tered at the time of the menstrual molimen, or just preceding the time when the flow should begin. If the case has been obstinate, a daily dose of apiol may be given for a week, or at least for several days be- fore the menstrual period. The neuralgic form of dysmenorrhoea is also benefited by this remedy. Other neuralgias are, it is said, relieved by apiol, but the existence of a malarial cause is, no doubt, the ex- planation of its curative action in such cases.

A fluid extract prepared according to the general directions of the United States Pharmacopoeia may be prescribed in the dose of ttj, x to 3 j. A solid extract is also to be found in the shops — dose, gr. j — gr. v. Actions and Uses. — The taste of hydropiper is hot, pungent, and acrid. The juice excites inflammation and vesication when applied to the external integument. In medicinal doses it causes a sensation of warmth in the stomach, and a " peculiar tingling sensation throughout the whole system" (Eberle). Unless given in an overdose it does not excite vomiting or produce purging. It stimulates the heart and arteries, increases the warmth of the surface, and promotes the cuta- neous, bronchial, and renal secretions. It stimulates the menstrual flow, and is aphrodisiac. This indigenous but little known remedy is a very efficient stimu- lating diuretic and emmenagogue. The author can confirm the state- ment of Eberle, who reports that " with no other remedy or mode of treatment has he been so successful as with this," in amenorrhcea. It is adapted to cases of amenorrhcea due to functional inactivity or tor- por of the uterine system, and is contraindicated when a condition of plethora or congestion exists. The administration of this remedy should be begun about a week before the menses ought to appear. Thirty minims of the fluid extract should be administered four times a day. If anaemia exist, iron should be given ; if constipation, aloes. Hydropiper is a remedy of considerable power in functional impo- tence. When the erections are feeble, the seminal fluid watery, and the testes soft, good results will be obtained from the use of this remedy, provided no structural alterations hinder or prevent improvement. When hydropiper is administered in these disorders of the sexual system, it causes a feeling of weight and tension, and dragging of the pelvic viscera. As it tends to increase the blood-supply to these organs, it is inadmissible when a state of congestion or inflammation exists. Authorities referred to : Eberle, Dr. John.

The leaves of Ruta graveolens (Pharm. 70, not official). Composition. — The medicinal activity of this plant depends on the presence of a volatile oil. Only the fresh leaves should be employed, and, as drying impairs the quality of the drug, the oil should be pre- scribed. URINO-GENITALS. 679 Oleum Rutce. — Oil of rue. This is a volatile oil, of a greenish- yellow color, very disagreeable and characteristic odor, and pungent, acrid taste. Dose, lU j — v\ v. Actions and Uses. — In its local action rue is an irritant ; applied to the skin, the oil causes heat, inflammation, and vesication. In ordi- nary medicinal doses a sensation of warmth follows its introduction into the stomach, and increased action of the heart and arterial system and a subjective feeling of peripheral heat are subsequently produced. The cutaneous, bronchial, and urinary excretions become more abun- dant, and the odor of the volatile oil is apparent in the breath, the sweat, and the urine. In toxic doses the oil of rue produces violent gastro- enteritis, prostration, convulsive muscular movements, hebetude of mind, etc., strangury and suppression of urine. In women the use of rue increases the menstrual flow, and large doses may cause abortion to take place. In men this agent promotes the sexual appetite, and increases the vigor of the erections. A tincture of the oil of rue is an efficient carminative and antispas- modic remedy in the flatulent colic and hysteria of women. Almost the only use of rue at present is in the treatment of amenorrhcea. It is one of the most efficient emmenagogues. Plethora, congestion, or inflammation of the pelvic viscera, contraindicate its use. Functional inactivity of the ovaries and uterus is the condition which justifies the employment of rue. It has been recommended in menorrhagia when the vascular tonus is low, and in uterine hcemorrhage after miscar- riage. It need hardly be remarked that the condition of pregnancy forbids the use of rue. Sabina. — Savine. The tops of Juniperus sdbina Linne (Nat. Ord. Conifer w). (U. S. P.) Sabine, Fr. ; Sabenhraut, Ger. Composition. — Savine contains an essential oil, in the proportion of two to two and a half per cent in the tops and about ten per cent in the berries. The oil of savine is isomeric with the oil of turpentine. Oleum Sabinaz. — Oil of savine. Dose, hi j — tij, v. Mxtractum Sabince Fluidum. — Fluid extract of savine. Dose, tt], v — nt xv. Actions and Uses. — Savine has a strong, disagreeable odor, and a pungent, acrid taste. Applied to the skin, the oil causes inflammation and vesication, if the contact be sufficiently prolonged. Introduced into the stomach in a full medicinal dose, a sensation of heat, eructa- tions tasting of the oil, flatulence, and nausea, are produced. A toxic dose sets up a violent gastro-enteritis. The oil diffuses readily into the blood, and is excreted by various channels — the breath, the sweat, and the urine smelling strongly of it. Increased action of the heart and a rise of tension of the arterial system, followed by diminished tonus of the vessels, result from its administration in full medicinal 680 EVACUANTS. doses. The cutaneous, bronchial, and urinary excretions are rendered more abundant by savine. Strangury and bloody urine are caused by it in overdoses. The evidence is conclusive that savine exerts a pow- erful influence on the uterine system. It increases the menstrual flux, and in toxic doses may originate uterine action and cause abortion. The abortifacient effect can not be obtained unless by the administra- tion of a quantity sufficient to endanger life. The only use to which savine is now applied is in the treatment of amenorrhcea. It is generally conceded that the estimate of its pow- ers made by Pereira is not extravagant, namely, that "it is the most certain and powerful emmenagogue of the whole materia medica." Savine is indicated in amenorrhoea dependent on deficient activity of the sexual system, accompanied by general atony. It is inadmissible when a tendency to congestion of the pelvic viscera is present, or in a condition of general plethora. Cases of dysmenorrhoea are benefited by savine when the subject is of relaxed habit, the menstrual flow be- ing scanty, provided narrowing of the cervical canal is not the cause of the painful and difficult menstruation. Menorrhagia, when due to an enlarged, relaxed, and passively congested uterus, and haemorrhage after abortion, may sometimes be arrested by this agent. The most effective preparation of savine is the oil. This may be prescribed in gelatin-capsules, in an emulsion, or in pilular form. The fluid extract, if made from the fresh tops, is an excellent preparation. Combination with other remedies of the same group increases the action of savine. $ 01. sabinse, 3 j ; ol. rutse, 3 j ; tinct. polygon, hydropi- per, § j ; ol. amygdal. express., mucil. acacise, aquae menth. pip., aa 3 ij.

Composition. — The principal constituent of cantharides is a neu- tral, crystallizable principle, cantharidin. It contains also an oil, fatty matter, and an odorous material. Antagonists and Incompatibles. — There is no chemical or physio- URINO-GENITALS. 681 logical antagonist to cantharides. Poisoning by this substance should, therefore, be treated on general principles. The stomach should be evacuated by emetics or the stomach-pump ; mucilaginous substances should be freely administered ; the gastro-enteritis should be treated by opium, etc. Synergists. — Oils and fats increase the solubility and favor the absorption of cantharidin. The physiological actions of this agent are promoted by the other members of this group. Physiological Actions. — The odor of cantharides is nauseating, fetid, and peculiar. In contact for a sufficient time with the skin or mucous membrane, it excites considerable burning, inflammation, and vesication. In the stomach it causes a sensation of heat, severe gas- tralgia, nausea, and vomiting. Notwithstanding the insolubility of cantharidin, it readily diffuses into the blood. It is actively stimulating to the circulatory system, and a rise of temperature, with thirst, follows in an hour or two. Under these circumstances, the urine becomes scanty and burns the passages ; severe pain is experienced in the back and loins ; priapism occurs ; and the urine, voided with great difficulty, frequently contains albumen and blood. To this excitement of the circulatory system and of the genital organs succeeds a condition of depression, in which the pulse falls, the arterial tension is lowered, and the temperature declines (Radecki). When a toxic dose is swallowed, in a short time a sense of constric- tion of the oesophagus, with difficulty of swallowing, and ptyalism, occur. Intense gastric pain, vomiting of glairy mucus streaked with blood, intestinal pain, abdominal tenderness, tenesmus, and mucous and bloody stools, are produced. Violent irritation of the genito-uri- nary organs is also experienced, manifested by lumbar pain, strangury and bloody urine, priapism, swelling and inflammation of the external genitals. In most cases of poisoning by cantharides, cerebral effects, consisting of muscular trembling, partial or general convulsions, coma, and insensibility are produced. Abortion has been caused by toxic doses of cantharides, and after death violent metro-peritonitis, gastro-enteri- tis, and general peritonitis, have been observed. It is questionable whether abortion can be caused by a dose less than toxic. Cantharides has frequently caused dangerous symptoms, when used with a view to induce venereal excitement. That it does promote the sexual appetite is probably true, but this result is accomplished only by the use of a quantity sufficient to cause vascular turgescence of the sexual organs. Therapy. — In acute desquamative nephritis, after the subsidence of the acuter symptoms, good results are obtained from cantharides. The local condition in which this remedy is serviceable consists in hyperemia with loss of vascular tonus. Chronic pyelitis and chronic catarrh of the bladder are occasionally remarkably benefited by the 682 EVACUANTS. long-continued use of small doses of cantharides. Irritability of the bladder, more especially as it occurs in women, without the existence of acute inflammation, and not produced by uterine displacements, is sometimes quickly and entirely relieved by this remedy. The irritable state of the bladder and the vesical tenesmus, which accompany chronic prostatic disease, are also sometimes surprisingly relieved by canthari- des, but the author is unable to indicate the special circumstances to which it is adapted. Gleet and prostorrhoea are benefited by cantharides when these maladies occur in subjects of a relaxed fiber, with feeble circulation. Ringer makes the extraordinary statement that one drop of the tincture given three times a day will prevent chordee. When spermatorrhoea actually exists, and is due to deficient tone of the seminal vesicles, the erections being feeble, and the sexual feeling torpid, good results are obtained by the use of cantharides. In cases of scanty menstruation, occurring in womeu of lax fiber, with cold hands and feet, improvement follows the use of this remedy. It some- times happens that menorrhagia is due to relaxed vessels and a general lowering of the vascular tonus : under such circumstances cantharides may render important service. In these disorders of the sexual system, characterized by deficient power, the good effects of cantharides are promoted by the use of iron. The tincture of cantharides is the most eligible preparation for internal administration. In chronic affections of the genito-urinary passages the dose will range from five to fifteen drops, rarely the latter, three times a day.

PAET III. TOPICAL REMEDIES. COUNTER-IRRITANTS. Exteenal irritation, utilized for the relief or cure of internal maladies, is entitled counter-irritation. The remedies employed for this purpose are divisible into two groups : 1. Rubefacients ; 2. Epispastics. A rubefacient is a remedy which causes heat and redness ; but, if the contact with the skin be sufficiently prolonged, vesication may be produced. An epispastic is a remedy which excites inflammation and vesication. The first group of remedies are restricted in their applica- tion to such therapeutical results as can be attained by a superficial and temporary action in the skin. The second group are intended for more permanent action and a deeper impression on internal organs. These remedies differ not only in the degree, but in the character of the effects produced. An impression on the periphery induces some kind of molecular modification at the center. According as the im- pression is slight or severe are the centric modifications localized to the point of reception or transferred to distant points (reflex impres- sions). According to the severity of the peripheral impression are the resulting local centric disturbance and the reflex changes (trophic alterations). Thus a slight peripheral rubef action may cause a trivial centric vascular spasm, but an extensive burn on the body may induce vaso-motor paresis, and consequent inflammatory changes in remote organs. RUBEFACIENTS. Sinapis Alba. — White mustard. The seed of Sinajns alba, Linne (Nat. Ord. Cruciferce). (IT. S. P.) Sinap>is Nigra. — Black mustard. The seed of Sinapis nigra. Charta Sinapis. — Mustard-paper. Composition. — When water is added to pulverized black mustard, pungent, irritating fumes are given off. These fumes consist of the volatile oil of mustard (allyl sulphocyanide). This volatile oil is pro- 684 TOPICAL REMEDIES. duced by a reaction between certain constituents of the seeds — sini- grin (myronate of potassium) and myrosin — in presence of water, and at a temperature below 100° Fahr. The boiling-temperature destroys the ferment, myrosiu, and hence prevents the formation of the volatile oil. Mustard contains also a bland fixed oil, which may be procured by expression. White mustard contains an indifferent, crystalline substance, sinal- bin, and myrosin. Sulphocyanate of acrinyl, a product of the reac- tion between sinalbin and myrosin, is the rubefacient principle of white mustard (Fliickiger and Hanbury). White mustard contains also an alkaloid — sinapine. The chemical composition of the two kinds of mustard is, it will be seen, closely analogous. Myrosin exists in white mustard in larger proportion than in black, hence a considerably larger quantity of the volatile oil of mustard is formed when an addition of white mustard is made to the black. A great variety of plasters and liniments (some referred to already in their appropriate connections) are employed to induce a rubefacient action. EHPLASTRA. Emplastrum Capsici. — Capsicum plaster (a resin plaster on which is spread a thin layer of oleo-resin of capsicum). Emplastrum Pesince. — Resin plaster (resin, lead plaster, and yellow wax). Emplastrum Baponis. — Soap plaster (soap, 10 parts ; lead plaster, 90 parts). Emplastrum Arnicce. — Plaster of arnica (extract of arnica, resin plaster). Emplastrum Picis Burgundicm. — Burgundy-pitch plaster (Bur- gundy pitch, 90 parts ; yellow wax, 10 parts). Emplastrum Picis Canadensis. — Canada-pitch plaster (Canada pitch, 90 parts ; yellow wax, 10 parts). Emplastrum Picis cum Cantharide. — Plaster of pitch with can- tharides (Burgundy pitch, 92 parts ; cerate of cantharides, 8 parts). LINIMENTA. Linimentum Calcis. — Lime liniment (equal parts of lime solution and cotton-seed oil). Linimentum Cantharidis. — Cantharides liniment (cantharides, 15 parts ; turpentine, q. s. to make 100 parts). Linimentum Sinapis Compositum. — Compound mustard liniment (volatile oil of mustard, extract of mezereum, camphor, castor-oil, and alcohol). Linimentum Ammonim. — Liniment of ammonia (water of ammonia, 30 parts ; cotton-seed oil, 70 parts). EPISPASTICS. 685 Linimentum Camphor ce. — Liniment of camphor (camphor, 20 parts ; cotton-seed oil, 80 parts). Linimentum Saponis. — Soap liniment (soap, 10 parts ; camphor, 5 parts ; oil of rosemary, 1 part ; water, q. s.; alcohol, 70 parts). Linimentum Terebinthince. — Liniment of turpentine (resin-cerate, 65 parts 5 oil of turpentine, 35 parts). An excellent rubefacient for long-continued use and moderate ac- tivity is the domestic spice-bag. This consists of a mixture in equal parts of cloves, cinnamon, allspice, ginger, and a half pint of capsicum, sewed into a flat bag. When required for use, it is dipped in vinegar or whisky, and laid over the affected region, usually the abdomen. A piece of flannel or spongio-piline may be moistened with the tincture of these aromatics, and applied for the same purposes. A turpentine-stupe, which is one of the most frequently-used ex- temporaneous counter-irritants, is made as follows : A piece of flannel folded in several layers, or a piece of spongio-piline, is wrung out in hot water, and a few drops (live to fifteen) of turpentine are sprinkled over it. This is placed over the affected region, and is confined by a towel or napkin pinned around the part. Turpentine, applied in this way, is a very active rubefacient, and may even vesicate, so that atten- tion is required to avoid overaction. EPISPASTICS. Ceratum Cantharidis. — Cantharides or blistering cerate. Ceratum Extracti Cantharidis. — Cerate of extract of cantharides. Charta Cantharidis. — Cantharides-paper. Collodium cum Cantharide. — Collodion with cantharides. Linimentum Cantharidis. — Liniment of cantharides. Firing. — By the method of firing, merely rubefacient or vesicating effects are produced. Firing is accomplished by the application of an iron disk provided with a suitable handle (Mayer's hammer). It is dipped into boiling water, and then passed, more or less rapidly, over the skin of the part to be acted on. Very brief contact suffices to vesicate, and this is the usual effect of the application. Of the above preparations the most efficient is the ceratum extracti cantharidis, the most elegant the charta cantharidis, and the most convenient the collodium cum cantharide. The cerates should be spread on adhesive plaster, leaving a margin of the plaster to secure adhesion to the skin. Before the application of a blister, if prompt action is necessary, a mustard-plaster should be laid on long enough to produce rubefaction, or the skin should be rubbed with turpentine. When the skin is very thin and sensitive, the blister should be covered with tissue-paper. When the vesication is to be permitted to heal in a short time, or when young and irritable subjects are to be blistered, the cantharides-plaster should be removed when distinct redness of the 686 TOPICAL REMEDIES. skin is produced, and a poultice applied, which will develop the vesi- cles. The length of time required for a blister " to draw " is influ- enced by the age of the subject and the condition of the skin. From two to twelve hours, as a rule, will elapse before vesicles appear ; and, when a very deep impression is intended, the blister may remain even twenty-four hours. In infants and in certain states of the constitution (scorbutus, purpura, scarlatina, etc.), prolonged contact of a canthari- des-plaster may cause deep sloughing and very severe nervous symp- toms, and adynamia. When the vesicles are fully developed, they should be punctured at the most dependent point, and the serum, as it escapes, absorbed by a soft cloth. If the blistered surface is to be allowed to heal, a dressing of raw cotton suffices. If discharge is to be encouraged, resin-cerate or savine-cerate may be applied, spread on a cloth perforated to permit the discharge to exude, and covered with raw cotton to absorb the fluid. If the blister is slow to heal, boracic-acid lotion is an efficient application, or a weak lead-lotion may be used. The Theory of Counter-Irritation. — When the skin is irri- tated, by a mustard- plaster, for example, the superficial vessels of the part dilate, and an increased amount of blood is present in them. For a short distance around the part irritated, also, more or less dilatation of the vessels takes place. In this way a small amount of blood may be temporarily imprisoned. The influence which the retention in an external part of so small an amount of blood has on the general circu- lation, must be very slight. The obvious relief often afforded by a mustard-plaster can hardly, therefore, be ascribed to this limited with- drawal of blood. An irritation established in the neighborhood of a part in which a morbid action is proceeding may, by reason of the contiguity of the tissues, affect the vascular supply to the diseased textures. TIM irri- tatio y ibi fluxus ; but, in order that the fluxion shall modify diseased action, it is necessary that there be a continuity of the vascular con- nections. The method of Furneux Jordan, which consists in the appli- cation of the counter-irritant to the neighboring vascular area, is based on this principle. An irritation which consists in a local fluxion, and a state of altered sensibility in the nerves of the part, may affect the functions of distant organs. Counter-irritation applied to a considerable surface increases the action of the heart, raises the temperature of the body, and exalts the irritability of the nervous system. These are the general or sys- temic effects. Distinctly-localized results are also produced. When one hand is immersed in cold water, a positive fall of temperature takes place in the other. Irritation of the lumbar region, as Brown-Sequard has shown, is followed by contraction of the vessels of the kidneys. Extensive injury to the surface of the body, by burning or scalding, EPISPASTICS. 687 may excite ulcerative action in the duodenum, or may set up a pneumo- nia. Injury to a motor-nerve trunk may be followed by ascending neu- ritis, and serious atrophic changes in the multipolar ganglion-cells of the anterior columns. It follows from these facts that an irritation of the surface which involves the end-organs of the nervous system will affect the caliber of the arterioles and modify the functions of the trophic nerves. In these results we find a rational explanation of the methodus medendi of counter-irritation. Certain other physiological laws deserve attentive consideration in this connection. An irritation which first produces a tetanic state of the vaso-motor nervous system may, if too long continued, exhaust the irritability of the organic muscular fiber, and cause paresis. Moderate irritation will exalt the functional power of the trophic centers ; but excessive and long-continued injury to the surface may set up atrophic changes (ulcer of duodenum from burn). In these physiological facts also we find a rational explanation of the injury not unfrequently done by too powerful or too protracted counter-irritation. Vesicants, in addition to the effects of counter-irritants sketched above, cause an exudation of serum. This exudation may have a two- fold effect : 1. To lessen the gross amount of the blood-serum, and thus diminish the blood-pressure ; and, 2. To remove toxic or patho- logical materials from the tissues and fluids of the inflamed part. More powerful systemic effects are produced, and vaso-motor paresis and trophic changes are more quickly induced, by blisters than by rubefa- cients. Therapy. — Various methods of counter-irritation are employed in the treatment of diseases of the abdominal viscera. For the relief of nausea, vomiting, diarrhoea, colic, cholera-morbus, etc., no expedient is more generally useful than a mustard-plaster. In persistent vomiting, a small blister applied to the epigastrium will often afford permanent relief. The good effects of a blister in such cases are enhanced by dusting over the exposed derma some powdered morphine. In acute inflammatory affections — typhlitis, peritonitis, puerperal peritonitis, pelvic cellulitis, etc. — the best results are obtained by the use of tur- pentine-stupes during the acute stage, and the application of blisters after the acuter symptoms have subsided. The prolonged contact of blisters with the abdominal wall of thin subjects has set up peritonitis by contiguity of structures. The author has observed instances of this kind, and analogous cases have been reported. In chest-diseases — pleuritis, pneumonia, pericarditis, etc. — some form of counter-irritation is invariably employed, and is often greatly abused. At the onset of these maladies a large mustard-plaster to the chest, allowed merely to redden the skin, is an excellent expedient ; during the progress of the inflammation the turpentine-stupe is gener- ally the best application ; to assist in the process of resolution and re- 688 TOPICAL REMEDIES. pair, the more permanent action of a blister will be serviceable. Much has been said about the " blistering-point " in pneumonia. The discus- sion is resolvable into this : during the inflammatory stage, blisters are harmful, because they stimulate the nervous and vascular system, and are useful when the crisis occurs, to assist in the liquefaction and ab- sorption of inflammation products. At the very inception of an acute thoracic disease a flying blister may render the same service as a mus- tard-plaster, but it possesses no advantage over the latter. A succes- sion of " flying blisters " appears to be useful in hydrothorax, to pro- mote absorption. Counter-irritants are much abused in the treatment of phthisis at its various stages. The chest-pains which accompany this disease can usually be relieved by mustard and belladonna plasters. Intercurrent attacks of pleuritis and pneumonia may be treated by the milder forms of irritation. The pustulation of the chest with croton-oil or tartar- emetic ointment is rarely if ever justifiable, and deep blistering is al- ways harmful. In acute inflammation of the meninges, cerebral or spinal, blisters are often employed, but there is singularly little proof of their utility. When used, they should be confined to the mastoid processes or to the nape of the neck. Under no circumstances is it ever justifiable to shave and blister the scalp, as was formerly not unfrequently done in various forms of cerebral disease. An aura proceeding from an ex- tremity may be intercepted, and attacks of epilepsy averted, by encir- cling the limb with a strip of blistering-plaster. Various instances of the success of such a blister have been reported. Hysterical paraly- sis is most successfully treated by encircling the affected extremity with narrow blisters (Reynolds), and hysterical aphonia may some- times be very quickly cured by a blister to the larynx. The curative effect of such an application is doubtless due to the moral impression of the counter-irritant. Blisters over the course of the affected nerve are of great service in neuritis. The good effect of the blisters is in- creased by treating the blistered surface with morphine. There can be no doubt of the curative value of blisters in neuralgice. According to Anstie, it is not the mental impression produced by the pain of the blister, and not the withdrawal of serum from the focus of pain, which explain their efficacy, but they act " as true stimulants of nerve-func- tion." The best point at which to apply the blister is " as close as may be to the intervertebral foramen from which the painful nerve issues." Flying blisters are to be preferred, and, as a rule, exudation of serum is not to be encouraged. Lumbago, myalgia, and fugitive but recurring muscular pains, are sometimes relieved by the warming plasters given at the head of this article, or by frictions with ammonia-liniment, turpentine-liniment, etc. Blisters are, as a rule, inadmissible in acute affections of the kid- EPISPASTICS. 689 neys and bladder. A succession of blisters to the perinseum is unques- tionably serviceable in chronic prostatitis and in gleet. Inflammatory affections of the eye and ear are, as a rule, benefited by the application of blisters in the neighborhood of these organs. The application of blisters is an effective method of treating acute rheumatism. According to the plan of Davies and Dechilly, the affected joints are enveloped in blisters, which are allowed to remain until thorough vesication is produced and serum is abundantly dis- charged. The author, who has had considerable experience in the treatment of rheumatism by this method, finds that a number of small blisters applied around the joint are as effective and less painful. The good effects of the blister-treatment are these : the pain and swelling are abated, the danger of cardiac complication lessened, and the dura- tion of the disease shortened. It is a singular fact that the urine be- comes neutral or alkaline under the action of blisters. The curative effect of blisters is not, probably, to be ascribed to the withdrawal of acid serum from the affected joints, but rather to an influence exerted through the trophic nerves on the metamorphosis of tissues. As general stimulants, rubefacients and vesicants are employed to arouse the vital processes in a condition of great depression or col- lapse from any cause, e. g., cholera, pernicious malarial fever, urazmia, narcotic poisoning, etc. Contraindications of Blisters. — The acute stage of an inflam- mation ; pregnancy ; scorbutus and purpura ; infancy ; debility ; are conditions rendering their use improper and injurious. The strangury produced by blisters is lessened by the free use of diluent drinks, and is relieved when it occurs by an enema of lauda- num or the hypodermatic injection of a minute quantity of morphine. A decoction of uva-ursi freely drunk will, it is said, prevent strangury, but the effect of this remedy is, probably, not greater than that of an ordinary diluent. The method of " firing " is sometimes very beneficial in neuralgia, spinal irritation, myalgia, etc. The effects can be regulated by the temperature of the hammer, and by the duration of the contact with the skin, and may vary in severity from the mildest rubefaction to vesication, and even destruction of the skin. Acupuncture. — Needles about three inches in length, and having a red wax, hard-rubber, or metal head, are employed for this purpose. They are introduced by a rapid rotary motion. Insulated needles are used in the same way for conveying the galvanic current to deeply- placed nerves. Baunscheidtismus. — This is a form of acupuncture, so named from Baunscheid, its inventor. " The instrument employed consists of a heavy disk, about half an inch in diameter, having inserted into it about twenty-five sharp needles, each about nine-sixteenths of an inch 44 690 TOPICAL REMEDIES. in length. To this disk a strong wire spiral spring (five and a half inches in length) is attached, and the other extremity of the spring is inserted into an elongated spindle-shaped handle." The spring and needles are contained in a cylinder, the handle attached. The follow- ing is the mode of using it : the open extremity of the cylinder is placed firmly on the skin ; the handle is then drawn up, which com- presses the spring ; now, if suddenly loosed, the recoil of the spring drives the needles smartly into the skin. The punctures maybe rubbed with a weak mixture of croton-oil, with cajeput-oil, or other suitable counter-irritant. Actions and Uses. — These are methods of counter-irritation which appear to possess peculiar powers. The theories which have been pro- posed to explain their mode of action are far from satisfactory. The method of Baunscheid is that of an ordinary counter-irritant added to the effects of acupuncture ; but no explanation has hitherto been offered which accounts, in a rational manner, for the curative effects of acu- puncture in certain maladies. In tic-douloureux, sciatica, lumbago, and myalgia, it occasionally happens that remarkable and instantaneous relief is obtained by the insertion of acupuncture-needles. When the patient is timid, the sensibility of the skin may be dimin- ished by the application of chloroform for a minute, or of the ether- spray. If rapidly rotated by the finger and thumb, the needle will penetrate with little suffering. Aquapuncture. — The method of aquapuncture consists in the in- troduction of water subcutaneously, or into the substance of muscles. A special instrument has been invented for this purpose, the advan- tage of which consists in its being armed with several needles, which permit the introduction of the water at various points simultaneously. Ordinarily, the hypodermatic syringe will suffice for the performance of this little operation, and, if patients object to repeated punctures, the sensibility of the skin may be obtunded by ether-spray. When water is injected under the skin, more or less pain, accom- panied by burning, is produced. A wheal is formed about the site of the puncture, and redness of the skin and elevation of the temperature at that point follow. It is a remarkable circumstance that aquapunc- ture has the power to relieve pain in a superficial nerve. So decided is this effect that there are physicians who hold that the curative effect of the hypodermatic injection of morphine is due, not to the morphine, but to the water ! In order that aquapuncture shall relieve pain, it is necessary that the water be injected into the neighborhood of the pain- ful nerve. Injection at a remote and indifferent point would certainly fail of any effect except that reflex effect which is produced by any counter-irritant. Aquapuncture, however, has unquestionable power as a counter-irritant. BLOODLETTING. 691 The method of aquapuncture has been employed with success, which must be regarded as extraordinary, in neuralgia}, facial, sciatic, and lumbo-abdominal ; in lumbago, irritability of the bladder, uterine colic, gastralgia, etc. The author has produced excellent effects from the injection of water into paralyzed and wasting muscles. It promotes the nutrition of muscles, and contributes to the regeneration of volun- tary power. In the various cases to which this treatment is appli- cable, the quantity which should be injected will vary from thirty minims to a drachm. When the first injection does not relieve in two minutes, another should be practiced. It is insisted upon (Lafitte) that the water be injected at the painful points (points douloureux). There need be no limit to the number of the injections, if they afford relief : for, of course, no injury will result, unless it be the production of an abscess at the site of the injections, which is very rare.

Venesection, arteriotomy, cupping, leeching. — The manner of bleed- ing, whether by opening a vein or an artery, is a surgical subject, which it is not necessary to consider in this work. Physiological Actions. — Bloodletting may be employed for a systemic or local effect. Bleeding from a vein or an artery, by dimin- ishing the whole quantity of the circulating fluid, and by altering its quality, affects the functions of every organ, and especially of organs the seat of an acute hyperemia. Cupping and leeching, if carried far enough, may diminish the general blood-pressure and the proportion of the morphotic elements ; but their action is largely local and revulsive. The effects of bloodletting on the composition of the blood are these : the water is increased and the globules, fibrin, and salts are diminished in relative amount ; an artificial anaemia is thus induced. The action of the heart becomes more rapid and its force lessened ; the arterial tension falls, and the pulse assumes the dicrotic character. The functions of organs, especially of the brain and nervous system, 692 TOPICAL EEMEDIES. lose energy. Nausea, vomiting, faintness, syncope, and epileptoid seiz- ures occur, when the loss of blood is considerable. Epileptiform con- vulsions is a constant phenomenon in animals bled to death (Kussmaul and Tenner). When the quantity of fluid in the vessels is lessened by bleeding, thirst is experienced, and absorption is more rapid ; the sensibility to pain is diminished, probably, because the perceptive centers are func- tionally inactive ; and the power to evolve force, muscular, digestive, nervous, etc., is greatly restricted. Only one function, therefore, is rendered more active by bleeding ; all the others are depressed in con- sequence of the inadequate supply of nutrient material. It is a remarkable fact, perfectly well known to old practitioners, and to which Sir James Paget has recently called attention, that the ill effects of bleeding, in healthy subjects, are very temporary and easily repaired. The blood-globules, which are relatively more affected by bleeding than the other constituents, are quickly reproduced, and the functions of organs suddenly very much depressed soon recover their normal energy. That any permanent injury is done to the healthy human system by a moderate bleeding seems, therefore, to be highly improbable. Therapy. — The limits of this work will not permit the introduc- tion of any controversial discussions. The author is to be ranked with those who do not employ general bloodletting, but he does not deny that it is occasionally useful ; and that, indeed, it may be indispensa- ble. A summary of the physical conditions in which venesection may be useful or indispensable should not, therefore, be omitted from a work on therapeutics. The therapeutical effect of a general bloodletting in congestion and inflammation is largely mechanical. In acute congestion of the lungs, when aeration of the blood is seriously impeded ; when there are ex- tensive stasis on the venous side, and ischemia on the arterial side of the systemic circulation, great relief may be afforded by the abstrac- tion of from four to sixteen ounces of blood. In the apoplectiform variety of acute cerebral congestion, damage to the brain may be pre- vented by letting blood. The effect of the bleeding is to diminish the intra-cranial pressure, and thus relieve the strain on the cerebral ves- sels. In eclampsia, especially of the puerperal variety, accompanied with the evidences of cerebral congestion, great relief may be procured by the timely abstraction of blood. The quantity of blood to be taken will depend in part on the character of the subject and on the amount of congestion. The mechanical effect of the withdrawal of blood from the systemic circulation may be most advantageous in cases of sudden over-disten- tion of the right cavities of the heart. Pulmonary haemorrhage, when dependent on acute congestion of BLOODLETTING. 693 the lungs, the general condition being one of plethora, may be promptly arrested by opening a vein in the arm. The pain of acute pleuritis, and acute peritonitis, can be quickly relieved by bloodletting. Although it is undeniable that the important results above men- tioned may be obtained from general bleeding, it is equally certain that as good results in most of the conditions may be had by other methods. Acute diseases make such serious demands on the vital resources of pa- tients, that the practitioner should seriously ponder the propriety of taking blood even in those cases to the relief of which it may seem to be adapted. Large bleedings, experience has abundantly shown, ren- der the convalescence from acute diseases tedious — for the patient has to make up the losses by venesection as well as the ravages of the disease. Bleeding by Cups and Leeches. — A large number of cups and leeches may produce the systemic effects of a general bleeding. But, as a rule, these applications are intended to withdraw blood from the affected part, and thus act in the manner entitled revulsive. The local irritation caused by cups and leeches must, through the agency of the nervous system, affect distant parts in the same manner as other coun- ter-irritants. Leeches are preferable to cups when the parts are very sensitive or inaccessible. The quantity of blood drawn can be more accurately measured when cups are used. The counter-irritant effects are much more pronounced from cups than from leeches. The amount of blood drawn by a leech will depend on its size, and the subsequent loss of blood, when the bleeding is encouraged, is de- termined by the vascularity of the part. As a general rule it may be stated that a leech will draw about four times its own weight — about one to two drachms. To obtain from any given patient four ounces of blood, one ounce of leeches must be applied. In acute gastric, enteric, and peritoneal inflammations, if the patient be plethoric, and there is decided sthenic reaction, leeches to the abdo- men are very serviceable. The number to be applied will always de- pend on the effect to be produced, employing the rules given above as the basis of the estimate. In typhlitis and perityphlitis, the author has seen such good results produced by leeches, that he holds they should never be omitted when the tenderness and fever begin. In acute hepatitis and congestion of the liver, and in acute dysentery, the best results are obtained by the application of leeches to the margin of the anus. Hemorrhoids that are swollen, painful, and irreducible without great suffering, are much relieved by the application of leeches directly to them. Pruritus of the anus, when due to engorgement of the portal circulation, and accompanied by heat of the anal region, may sometimes be cured by leeching the parts affected. 694 TOPICAL REMEDIES. Acute desquamative nephritis, pyelitis, and congestion of the kid- neys, are ameliorated by the application of cups to the lumbar region. The following acute affections of the respiratory organs, when they occur in robust persons, and are accompanied by sthenic reaction, are favorably influenced in their course and duration by the application of cups or leeches — usually the former : pleuritis, pericarditis, acute ton- sillitis, acute laryngitis, and inflammatory croup. In acute inflammations of the uterus and its appendages, decisively good results are obtained by the application of leeches to the hypogas- tric region, to the iliac fossae, or to the uterus. Cupping the nape of the neck, or leeches to the mastoid process, are probably of service in acute congestion or inflammation of the intra- cranial structures ; but the indiscriminate employment of bloodletting in any case of cerebral disease is to be condemned. The correct rule may be formulated as follows : When bloodletting is indicated in in- tracranial maladies, venesection or arteriotomy (temporal artery) is to be preferred to the use of cups or leeches. Although good results are obtained by the local abstraction of blood in the diseases above mentioned, the author must express his convic- tion that the chief utility of cupping and leeching consists not in the blood withdrawn, but in the derivant and counter-irritant effect which they produce. Dry cups, a mustard-plaster, a turpentine-stupe, or other counter-irritant application, may render the painful process of cupping or leeching unnecessary. ESCHAROTICS. The substances belonging to this group are employed for the pur- pose of destroying the tissues to which they are applied. They differ in their mode of action, in the extent of the destruction which they effect, in their capacity for diffusion into the blood, and in the results which they severally accomplish. They are prescribed for the purpose of cauterizing poisoned wounds — syphilitic ulcers, snake-bites, the bites of rabid animals — for the re- moval of gangrenous parts, foul or exuberant granulations, and espe- cially for the destruction of malignant growths. When the diseased parts, to the destruction of which they are devoted, have been fully acted upon, the caustic action is ended ; poultices are applied to favor the entire separation of the sloughs, and a healthy surface is finally left to heal by granulations. The members of this group have, with one exception, been dis- cussed elsewhere : The mineral acids. The chloride and sulphate of zinc. Potassa fusa and potassa cum calce. Arsenious acid. DEMULCENTS. 695 The acid nitrate of mercury. Bromine. Acidum Chromicum. — Chromic acid. In deep-red, needle-form crystals, deliquescent, and very soluble in water, forming an orange- red solution. Actions and Uses. — Chromic acid is an oxidizing caustic. When the action ceases, sesquioxide of chromium remains. It is slow in ac- tion, and not very painful, but it penetrates deeply and is remarkably destructive. Small animals, as mice and birds, are dissolved entirely, bones and all, by chromic acid. Owing to the fact that it penetrates deeply without much pain, care must be used in its application as a caustic, lest it injure parts which are not intended to be affected. When it is applied as a caustic, the surrounding tissues must be well protected. For the destruction of malignant growths, haemorrhoids, warts, etc., the acid should be made into a paste by the addition of sufficient water. The part to which it is applied first becomes yellow, then brownish, and ultimately black, and the eschar is detached in from twenty-four to forty-eight hours. A solution of chromic acid of the strength of one hundred grains to an ounce of distilled water is an efficient local application in syphilitic warts and vegetations, condylomata, lupus, sycosis, tinea tonsurans, etc. A still stronger solution (grs. xv — 3 j of hot water) has been in- jected into the uterine cavity with success in cases of uterine haemor- rhage and uterine catarrh (Wooster).

A colorless, inodorous, sirupy liquid, of a sweet taste, and having the specific gravity of 1*25. It is soluble in water and in alcohol, but not in ether. Glycerin- Ointment. — (Unofficial.) (Spermaceti, f ss ; white wax, 3 j ; oil of almonds, f ij ; glycerin, § j — add the glycerin to the melted ingredients, and stir briskly till cold.) (Squire.) Glyceritum Vitelli. — Glyconin. An emulsion of glycerin and the yelk of eggs — 45 parts of the yelks and 55 parts of glycerin. (IT. S. P.) Glycerin- Cream. — (Glycerin, 1 ; soft soap, 1 ; cherry-laurel water, 1.) (Squire.) Glycerin- Cream with Camphor. — (Glycerin, 2 ; camphor, 1 ; recti- fied spirit, 1.) (Squire.) 696 TOPICAL REMEDIES. Glyceritum Amyli. — Glycerite of starch. (Starch, 10 parts ; gly- cerin, 90 parts.) (U. S. P.) Properties. — Exposed to the air, glycerin slowly absorbs moist- ure, but it does not evaporate, and it does not become rancid or under- go fermentation spontaneously. It is unctuous to the touch, and is obstinately sticky. Glycerin possesses remarkable solvent powers. One part of iodine and one of iodide of potassium dissolve in two parts of glycerin. Bromine, the iodide of sulphur, the chlorides of potas- sium and sodium, the alkalies, some of the alkaline earths, many of the neutral salts, the vegetable acids, especially tannic, most of the alka- loids (morphine, quinine, strychnine, veratrine, and atropine), and car- bolic acid, are soluble in glycerin. The fatty acids, cocoa-butter, camphor, chloroform, calomel, iodide of lead, and the resins, do not dissolve in glycerin. The antiseptic property of glycerin is decided. Vaccine lymph may be preserved unchanged almost indefinitely when stored up in pure glycerin ; and anatomical preparations, and specimens of natural history, are kept in preservative solutions consisting chiefly of this substance. Microscopical and pathological specimens are after a time softened and disintegrated by pure glycerin. Applied to the tissues of the body, glycerin, if pure, is perfectly bland and unirritating, as a rule, but in some subjects severe smarting is produced on contact of the purest glycerin with the mucous mem- brane. When it contains the fatty acids, oxalic or formic acids, it possesses very positive irritant qualities. It abstracts water from the tissues. Therapy. — No systemic effects are produced by the stomach ad- ministration of glycerin. It is an efficient remedy in acidity, pyrosis, and flatulence, in the dose of a drachm, before, with, or after meals. Glycerin has been proposed and used as a substitute for cod-liver oil, in the various cachectic states in which the latter is prescribed. It has been conclusively shown that it is inferior to cod-liver oil in every respect. As a vehicle for the administration of cod-liver oil, it is extremely serviceable (glyconin, a teaspoonful ; cod-liver oil, a tea- spoonful ; tincture of cinnamon, ten drops). Good results have been reported from the use of glycerin in dia- betes, but the data are as yet insufficient to enable a correct estimate of its real value to be made. The internal administration of glycerin has been resorted to for the removal of acne with success. It is said to destroy intestinal trichina, and may be given freely in trichi- nosis. The most important applications of glycerin, besides its numerous uses as a vehicle, are topical as an emollient. Applied to the affected mucous membrane by means of a camel's-hair pencil, pure glycerin affords great relief in acute coryza. Chronic follicular pharyngitis, PROTECTIVES. 697 accompanied with profuse secretion, is generally improved by the same application, but the addition of tannic acid greatly enhances its cura- tive power in this affection. A solution of morphine in glycerin, ap- plied to the fauces with a brush, relieves the cough of phthisis. A better application in many respects is a mixture of glycerin, crystal- lized sugar, and whisky. This mixture, allowed to trickle slowly down the fauces, allays irritability and keeps the mucous membrane moist (glycerin, two parts ; whisky, one part ; crystallized sugar, a suffi- ciency). An enema of glycerin and infusion of flaxseed (one to four) allays the tenesmus in cases of acute dysentery. For chapped hands or face, glyconin is an excellent application. In seborrhoea, glycerin-cream gives good results. F 'or fissures of the nipple, Stille strongly recommends a " liniment made by adding one part of tincture of benzoin to six or eight of glycerin, and filtering the mixture." In pityriasis and in the papular eruptions, glycerin is serviceable, but, in general, it may be stated that its use in skin-diseases is disap- pointing, and that it is inferior as a local application to the usual oils and fats employed in this way. Glycerin has been used as a dressing for wounds and ulcerated surfaces, with more or less advantage. It is largely prescribed by gynaecologists as a topical application to erosions and ulcerations of the cervix uteri, and for the relief of vaginal leucorrhcea. The glycerite of starch (plasma) is an excellent vehicle for the ap- plication of astringents to the eye, and is much employed by ophthal- mologists for this purpose. Glycerin is used by otologists to soften cerumen, to entangle insects which have entered the ear, to diminish the secretion of pus, and to relieve the morbid state of the auditory canal in cases of otorrhcea. Collodium. — Collodion. Is a slightly opalescent liquid, of a sirupy consistence. By long standing it deposits a layer of fibrous matter, and becomes more transparent. This layer should be reincorporated, by agitation, before the collodion is used. When applied, it should form a colorless, transparent, flexible, and strongly contractile film. Collodium Flexile. — Flexible collodion. (Collodion, ninety-two parts ; Canada turpentine, five parts ; castor-oil, three parts.) Liquor Gutta-Perchae. — Solution of gutta-percha. (Gutta-percha, nine parts ; carbonate of lead, ten parts ; commercial chloroform, ninety-one parts.) Actions and Uses. — These solutions, when applied to the integu- ment, evaporate, leaving a transparent film or coating impervious to air and moisture. In drying, collodion contracts energetically, and 698 TOPICAL REMEDIES. may indeed produce such a degree of constriction as to cause pain, and to render the part bloodless. Flexible collodion contains turpen- tine and castor-oil, which confer the property of flexibility, while they do not impair the impermeability of the film. The solution of gutta- percha has properties similar to flexible collodion. These solutions are employed to protect exposed parts from the contact of air, to secure primary union of incised wounds, to cause resolution of inflamed parts by mechanical pressure, etc. Some cases of chronic tubercular and squamous skin-diseases are much improved by coating them with the gutta-percha solution. Pre- vious to the application of the solution all scales should be removed. Excellent results have been obtained in herpes zoster by a thick coating of the flexible collodion or the gutta-percha solution : the pain is re- lieved, the vesicles aborted, and the duration of the disease shortened. As this is a self -limited disease, there must remain a suspicion of post hoc rather than propter hoc. Erysipelas, especially of the traumatic variety, is, at least, much relieved as regards the local symptoms by a thick coating of flexible collodion, but there is no evidence that it actu- ally shortens the duration of the disease. Burns to the first degree are greatly benefited by the same application ; it prevents contact of the air, and allays the irritation and pain. When, however, there is much exudation, or sloughing takes place, an impermeable coating adds to the distress. Collodion has been used without much success in small-pox, to hin- der the development of the pustules. Small boils, carbuncles, nmm, and even superficially placed aneurisms, may be so compressed as to arrest the local inflammation or to cause coagulation of the blood. Orchitis may be treated by a coating of collodion, instead of strapping. When the mechanical effects of the collodion are to be obtained, suc- cessive layers must be applied. Fissures of the nipples are best treated by flexible collodion or gutta- percha solution. The fissures are carefully wiped dry, well approxi- mated, and then thoroughly coated. Nipples that are retracted may be made more prominent by surrounding them, after being well drawn out, with a thick layer of collodion so placed that on contracting it will pucker the skin of the areola. Collodion has been used with success as a means of compression in umbilical hernia, spina-bifida, varicocele, etc. Chondrus. — Chondrus crispus. Irish moss. Cetraria. — Cetraria Islandica. Iceland moss. Decoctum Cetrarim. — Decoction of Iceland moss. Composition. — The principal constituent of chondrus is a mucilage, which, when dry, is horny, but swells up in water, forming a jelly. DEMULCENTS. 699 Cetraria contains about seventy per cent of a starch (lichen-starch), a decoction of which gelatinizes on cooling. In addition to this starch cetraria contains a bitter principle (cetrarin), and a peculiar acid (lich- eno-stearic acid). These lichens are used only for the production of diets for the sick. They were formerly supposed to possess some peculiar virtues which rendered them serviceable to pulmonary invalids. As articles of food, they have a very low position as regards nutritive value. The decoc- tion of cetraria may be used as a stomachic tonic, containing as it does a bitter principle ; but it is only to be prescribed when the more effi- cient remedies are not well borne. Chondrus may be made into jelly or blanc mange, in the same way as gelatin is now prepared for this purpose. Neligan gives the fol- lowing recipe for the preparation of a jelly from chondrus : Chondrus, washed and macerated, thirty grains ; spring-water, a pint ; boil down to one half and strain with expression, and add to the strained liquor four ounces of white sugar, one ounce of gum-acacia, and thirty grains of powdered orris-root ; heat to dryness with a gentle temperature, stirring constantly so as to obtain a pulverulent mass, to which three ounces of arrow-root are to be added by trituration. A jelly is pre- pared with this powder by rubbing up a teaspoonful of it with a little cold water, and then pouring a cupful of boiling water on it. Acacia. — Gum-arabic. A gummy exudation from Acacia vera, and other species of Acacia. Mucilago Acacias. — Mucilage of gum-arabic. Syrupus Acaciai. — Sirup of gum-arabic. (Mucilage of acacia, 25 parts ; sirup, 75 parts.) Tragacantha. — Tragacanth. The gummy exudation from Astraga- lus gummifer, and from other species of Astragalus. Mucilago Tragacanthoe. — Mucilage of tragacanth. Sassafras Medulla.— The pith of the stems of Sassafras officinale. Mucilago Sassafras Medullas. — Mucilage of sassafras-pith. Actions and Uses. — These preparations are used as demulcent drinks, in cases of acute inflammation of the stomach and intestines. They are supposed to make a protective coating on the inflamed part, and thus save it from further injury. They are especially indicated when irritating and corrosive substances have been swallowed. They are also frequently prescribed as diet-drinks in fevers and in acute in- flammations, in accordance with the supposition that they are not only soothing to the alimentary canal, but are, in a limited sense, foods. As nutrients these gums and mucilaginous substances rank very low, and can by no means take the place of such a food as milk. Furthermore, 700 TOPICAL REMEDIES. they are exceedingly apt to undergo fermentation, and to produce flatu- lent colic and diarrhoea. Mucilaginous drinks are very frequently taken in catarrhal affec- tions of the bronchial tubes and of the kidneys, with the view to mod- ify the morbid process going on in these parts. It need hardly be stated that such a theory of the utility of demulcents is erroneous. Cough is modified by an influence which is probably reflex, when mu- cilages are applied to the fauces ; but in no other way can the mucous membrane of the air-passages be affected by such remedies taken into the stomach. As gums undergo digestion in the alimentary canal, it is obvious that they can not act as demulcents on any part of the urinary tract. The chief use of these remedies is in extemporaneous prescriptions, to hold insoluble medicines in suspension, and to cover the taste of dis- agreeable ingredients. Linum. — Flaxseed. The seed of Linum usitatissimum. Lini Farina. — Flaxseed-meal. Infusum Lini Composition. — Compound infusion of flaxseed. (Flaxseed, f ss ; licorice-root, 3 ij ; boiling water, Oj.) (Not official.) Ulmus. — Slippery-elm bark. The inner bark of Ulmus fulva. Mucilago TJlmi. — Mucilage of slippery-elm bark. Glycyrrhiza. — Licorice-root. The root of Glycyrrhiza glabra. Extr actum Glycyrrhiza}. — Extract of glycyrrhiza (licorice). Extractum Glycyrrhiza} Purum. — Pure extract of glycyrrhiza. Extr actum Glycyrrhiza} Fluidum. — Fluid extract of glycyrrhiza. Mistura Glycyrrhiza} Composita. — Compound licorice-mixture (brown mixture). A simple expectorant containing paregoric, wine of antimony, and spirits of nitrous ether. Dose, 3 j — ? ss. (Not official.) Actions and Uses. — The remedies of this group contain mucilagi- nous constituents on which their properties depend. They are fre- quently prescribed as protectives in gastro-intestinal disorders, and as expectorants in bronchial affections. Poultices. — Flaxseed-meal, powdered slippery-elm bark, and Indian or corn meal, are most frequently used for the preparation of poultices. Wheat-bread and milk are also occasionally employed for the same purpose. In the preparation of a poultice, the meal is slowly incorporated with hot water, until a mass of the proper consistency is made. The mixture itself should not be applied immediately to the part, for it dries and adheres with considerable tenacity. A piece of washed mus- lin of quadrangular shape, and of sufficient size, is selected ; the hot POULTICES. 701 mass is spread on one end of the muslin, leaving a margin of one inch on three sides ; the long end of the muslin is then folded over the mass, and the free margins are stitched or pinned together. If the poultice is not frequently renewed, to prevent drying, some glycerin should be added to the surface which is to remain in contact with the tissues. Laudanum, or other narcotics, may be stirred in with the meal if the relief of pain be desirable. A yeast-poultice consists of brewers' yeast, to which sufficient flax- seed is added to give the proper consistence. A charcoal-poultice differs from an ordinary poultice in having powdered charcoal incorporated with the mass. In order that a char- coal-poultice shall have the proper consistence, the mass should be thin enough to take up a sufficient quantity of charcoal. Actions and Uses. — A poultice is a means of applying continu- ous heat with moisture, and of softening the tissues. An afflux of blood takes place to the part, the vessels dilate, the tissues, softened by the combined influence of heat and moisture, permit the easy diffu- sion of the fluids. If the process of inflammation has begun, or is in progress, the stasis is relieved, the tension of the inflamed part is less- ened, and resolution is thus favored ; or, if the stage of exudation is reached, the migration and multiplication of the white corpuscles are promoted, and the extrusion of purulent elements facilitated. The accumulation of blood in the neighborhood of the poultice seems to diminish the pressure elsewhere, and thus poultices of large size lower the arterial tension and lessen stasis in internal parts. Poultices re- lieve the pain of inflamed parts by relaxing the tissues, and thus re- moving pressure from the sensory nerve-filaments. The impression thus made on the peripheral nerve-endings is transmitted to the center and reflected over internal organs. It is within the range of every- body's personal experience that warm, moist applications relieve pain in internal and distant parts, which have no anatomical connection with the integument to which the applications are made. Poultices have, therefore, a local and a systemic effect. Their therapeutical uses are based on this conception of their physiological actions. They are prescribed to relieve the tension and to promote resolution or suppuration in boils, carbuncles, and other superficial in- flammations, to hasten the healing of irritable ulcers, to favor the sep- aration of gangrenous sloughs, etc. Foul-smelling wounds requiring the use of poultices are best treated with the yeast or charcoal poul- tice. Unquestionable benefit is derived from the application of hot poultices externally in acute faucial inflammations, in pneumonia, pleuritis, pericarditis, hepatitis, peritonitis, etc. The application of poultices sometimes degenerates into abuse. If too long continued, the skin becomes white, wrinkled, and sodden ; 702 TOPICAL REMEDIES. small abscesses or boils form, and the vessels of the parts very slowly regain their tone. If kept too long in contact with wounds or ulcer- ated surfaces, the granulations become pale and flabby, and the heal- ing process is retarded. Applied indiscreetly to inflamed joints, they may promote suppuration, and thus permanently injure these struc- tures. If kept long in contact with a large extent of surface, they will lower the general tone and vigor of the system, depress the sys- temic circulation, exhaust the irritability of the vaso-motor nerves, and thus seriously embarrass the reparative process, if not wholly prevent repair.

The frequent use of alkalies en- hances the mischief. Lime-water, 199. Car- bonate of Ammonia, 213, Alkaline Mineral- waters, 205. Tannic Acid, 299, in pill-form— VI j glycerin to gr. iv of tannin. Carbolic Acid, 326, stops fermentation and eructations. Bismuth, 143, with carbolic acid, gives excel- lent results. The purified black Oxide of Man- ganese, 137, and Oxide of Silver, 263, are ser- viceable, acting as local sedatives and preventing acid fermentation. Acetate of Lead, 275, Kino, 300, and JVux Vomica Tincture, 397, act in the same, and rather remove the causes than affect the acidity directly. Acne : Phosphorus, 118. Even more effective and safer are the hypophosphites and phosphates. Ar- senic, 153; sometimes beneficial, but on the whole disappointing. Bismuth, 144, is an ex- cellent topical application when there are heat and redness. SubUmed Sulphur, 630, applied as a powder to the eruption is one of the best applications. Alkaline lotions, when the skin is greasy and the sebaceous follicles full, are useless; for example, liquor potassce in rose- water, 200. Lotions of corrosive sublimate, 256. Glycerin, 697, internally. Adynamia : Alcohol, 478, is serviceable when it improves the appetite and digestion, when the tongue be- comes moist, and when delirium subsides under its use. Brandy is the best form when bowels are relaxed ; whisky when there is constipation. A wine of good body and high bouquet in the weakness of sedentary occupations. Aliment, 53, beef, milk, cod-liver oil. Bitters, especially calumba, 160, and hydrastine, 166, as a substi- tute for quinine. Eucalyptus, 163, for malarial adynamia, but especially the alkaloids of cin- chona, notably quinine, 177, gr. ij — gr. v, ter in die. Iron, 130, to stimulate digestion and promote blood formation, with manganese. Chalybeate springs, 139. JVux Vomica Tinc- ture, 297, with capsicum in the case of inebri- ates. Coca, 467, prevents waste, and favors constructive metamorphosis. After-pains: Chloral, 514, one of the most efficient remedies, but considerable doses necessary. Camphor, 457, effective, with or without morphine. Gel- semium, 563, also stops after-pains ; but, as large doses are necessary, safer remedies are preferable. Morphine and atropine, 535, sub- cutaneously or by the stomach, very certain to relieve, 543. Cimicifuga, 433, affords some re- lief. Albuminuria : Milk cure, 46, especially buttermilk, 47. Iron, 133, and the purgative chalybeate waters, 139, for the anaemia. Arsenic, 153, for the intersti- tial changes in kidneys. Alkaline diuretics, 195.

CLINICAL INDEX. 713 Alcoholism: Bromides, 543, especially for the "horrors," in 3 - doses. Capsicum, 671, for its stomachic tonic and hypnotic qualities. Chloral, 513, very effi- cient in the acute form, but caution is required in old drunkards. Opium, 531, but cautiously. Zinc Oxide, 281, for the chronic state, with piperine or capsicum. Cinchona, 176, 183, es- pecially the C. Eubra fluid extract. Lupulin, 537, fluid extract with capsicum ; good substi- tute for alcoholic stimulants. Picrotoxin, 407, for the muscular tremors. Nux Vomica, 39S, nerve and stomachic tonic. Amaubosts : Strychnine, 400, hypodermically, curative in functional disease caused by tobacco, alcoholic excess, etc. Amenobbhosa : Aconite, 601, for sudden suppression due to cold. Aloes, 642, when due to anaemia and torpor. Iron, 132, when anaemia is the cause, may be given with nerve stimulants, as nux vomica. Chalybeate Waters, 139. Apiol, 677, and Hy- dropiper, 678, when there is functional inactiv- ity of ovaries, preceded by a chalybeate course, by aloes, apiol being given just before the period for several days. Arsenic, 154, as a reconstit- uent, combined with iron. Aurum, 259, a stimulant of the menstrual function. Asafozti- da, 459, for the nervous disturbance and as an ovarian stimulant. Electricity , 3S7, faradic and static ; very efficient to start the flow when suitable preparation has been made. Ergot, 416, is useful when plethora exists. Rue, 679, and Savin, 6S0, are active stimulants, to be given with great caution. Pulsatilla, 608, used under the same circumstances as aconite in sudden arrest of flow. Anaemia : Compressed Air, 81. Oxygen, 319. Iron, 130. Arsenic, 151, an adjunct of iron, or when the latter can not be borne. Pepsin, 90, and Pan- creatin, 92, to aid the primary assimilation. Lacto-phosphate of lime, 121, a material need- ed in the anaemia of lactation and of suppura- tion. Manganese, 137, of use when associated with iron. Galvanization, central, and gen- eral faradization, 386, to stimulate the functions of organic life. Wines, 483, especially the red wines with good body. Anaesthetics : Eules for administration, 498. Morphine, subcu- taneously by the method of Bernard, 499, facili- tates the inhalation, lessens the dangers, and prolongs the anaesthetic stage with a less quan- tity of the anaesthetic. Whisky, 499, adminis- tered before inhalation, sustains the heart and prolongs the narcosis. Means of restoration, 500, depressing head, drawing out tongue, arti- ficial respiration, inhalation of ammonia, or in- travenous injection of the same, faradization of chest-muscles, electro-puncture of the heart, etc. Anesthesia : Magnetism, 3S1, and Metallotherapy, 289, for the hysterical state, and for other forms the electric brush, 3S6, and strychnine, 402. Aneubism : Aliment, 41, 46, denutrition cure. TufnelTs plan, 41. Barium Chloride, 217, acts by raising the arterial tension, and has been used successfully. Iodides, 231, in full doses, relieve pain, and promote coagulation of blood in the sac. Ace- tate of Lead, 276, depresses the heart and raises the arterial tension. Veratrum Viride, 605, 6lows the circulation, and thus facilitates coagulation in the sac. Aconite and other ar- terial sedatives act similarly; but their action must be aided by a proper diet and absolute recumbency. Ergot, 414, especially ergotin subcutaneously, has been very effective. Gal- vano-puncture, 288, has but rarely succeeded. Angina Pectoris: Amyl Nitrite, 593, by inhalation, affords prompt relief in cases characterized by elevated arterial tension, but must be used with caution when arteries are atheromatous and heart is fatty. Nitro-glycerin, 596, acts similarly but more slowly, and is more manageable. Arsenic,152, in full doses, is very efficient as a means of pre- vention. Ether, 4S9, in small quantity by in- halation, may abort a mild attack, hypoder- matically, in the worst cases, 490. Antidotes : For the Mineral Acids, 95. Alkalies, soda, lime- water, soap, and protectives, as oil, mucilage, etc. For the systemic depression: alcohol, opium, and especially carbonate of ammonia. For Phosphorus, 110. Emetic of sulphate of cop- per, French turpentine, or old, unrectified tur- pentine, hydrated magnesia, laxatives, trans- fusion. Oils and fats aid the absorption of phosphorus, but mucilaginous protectives are useful. For Arsenic, 146. Hydrated sesquioxide of iron,, dialyzed iron, hydrated magnesia, emetics, the stomach-pump ; opium and alcoholic stimulants for the systemic depression. For the Caustic Alkalies, 188. Diluted acetic acid, vinegar, soap, oil ; opium and stimulants for the systemic depression. For Barium, 216. Emetics, protectives, hydrat- ed magnesia, tannin, especially diluted sulphuric acid, and nitrite of amyl, and nitro-glycerin to counteract the elevated arterial tension. For Sulphxirous Acid and Sulphites, 220, and the Sulphides, 222. "Weak acids, chlorine-wa- ter, sulphate of iron, common salt, etc. For Iodine and its poisonous compounds, 228. Starch is the antidote for iodine; but, as the iodide of starch is not without power, emetics should also be given. Albumen, starch, lime- water, tannin, soap, etc., should be used in poi- soning by iodides, and free emesis should be induced. For Iodoform, 242. For Mercury and its compounds, 247. Albu- men, the carbonated alkalies, tannin, lime-wa- ter, should be administered freely. Emetics should be given. For the usual systemic symp- toms, opium, alcoholic stimulants, etc. For Gold and its Chlorides, 258. Same as for mercury. 714 CLINICAL INDEX. For Silver, 261. Common salt freely, albumen, tannin, and emetics. For Copper, 268, and Zinc, 278. Albumen, tan- nin, lime-water, soap, oil, and mucilage ; and the usual systemic remedies. For Lead, 273. Diluted sulphuric acid, alum, Epsom salts, milk ; emetics and purgatives, and iodides and bromides to secure elimination. For Antimony, 284. The vegetable astringents, tannin, albumen, oil, mucilage, and opium and stimulants to counteract the depression. For Nux Vomica and its Alkaloids, 392. Chlo- ral, ether and chloroform, gelsemium, bromide of potassium, are the physiological antagonists ; tannin is a chemical antidote. For Picrotoxin, 405. The physiological antago- nists and the antidotes are the same as for strychnia. For Ergot, 409. The caustic alkalies, aconite, but especially amyl nitrite. For Digitalis, 422. Aconite, saponaria, amyl ni- trite, and nitro-glycerin, are the physiological antagonists; tannin, sulphate and chloride of iron, are chemical antidotes. For Belladonna and its alkaloid Atropine, 435. Opium or morphine, physostigma or eserine, and pilocarpine, are the most efficient antagonists. The caustic alkalies destroy the active prin- ciple, but the available chemical antidotes are tannin, compound solution of iodine, charcoal, etc. For Stramonium, Hyoscyamus, and Duboisia. The antagonists and chemical antidotes are the same as for belladonna. For Camphor, 455. Caffeine the arterial seda- tive. For Cannabis Indica, 463. Caustic alkalies, strychnine, faradic electricity. For Chloroform.— By the stomach, 492. The stomach-pump, oil and mucilage, atropine, fara- dism, artificial respiration, and cold affusion. By inhalation, 498. Nelaton's method (inver- sion of the body), drawing out the tongue, arti- ficial respiration, faradism, ammonia by inha- lation and intravenous injection, amyl nitrite by inhalation, subcutaneous injection of tincture of digitalis. Oxygen, 319, by inhalation. For Chloral, 509. Ammonia, atropine, galvan- ism, and heat, to overcome the cardiac depres- sion. Strychnine is the antagonist of Liebreich, but its range is limited. Eserine, to a slight ex- tent, is physiologically opposed. For Opium, 518. The stomach-pump, or emetics (bicarbonate of sodium, followed by tartaric acid, has acted favorably) ; cold affusion, faradi- zation, and artificial respiration, when the res- piration flags ; belladonna, or atropine subcuta- neously, has acted favorably in numerous cases ; caffeine injected, or black coffee. For Conium, 551. Chemically the caustic alka- lies and tannic acid are antidotes ; emetics or the stomach-pump, cold affusion, artificial respi- ration. Atropine and strychnine, subcutane- ously, to counteract the respiratory depression. For Curara, or Woorara, 555. Caustic alkalies and tannin act chemically ; artificial respiration is of the highest importance ; atropine and strychnine counteract the respiratory failure. Cold affusion and emetics, or the stomach- pump, are necessary. For Gelsemium, 560. Chemically caustic alka- lies and tannic acid. Emetics, warmth, am- monia, faradization of chest-muscles, artificial respiration, and morphine, subcutaneously, are the important measures. For Pilocarpus, 567. The persalts of iron and the salts of the metals are chemically antidotal. Atropine is, in a very complete degree, the phys- iological antagonist ; cardiac stimulants, as am- monia and alcohol, antagonize the heart's weak- ness. For Physostigma, 574. The vegetable astrin- gents and tannin, chemical antidotes. Physio- logical antagonists are, atropine to a considerable extent — chloral, apparently, more completely. Faradization of chest-muscles and artificial respiration are important measures. Emetics should not be omitted. For Tobacco or Nicotine, 579. Emetics or stomach-pump. Tannin, compound solution of iodine, chemical antidotes. Ammonia, brandy, atropine, and strychnine to. overcome failure of respiration ; also, artificial respiration, cold affu- sion. For Hydrocyanic Acid and Cyanide of Potas- sium, 5S3, 5S9. Cold affusion to the spine, arti- ficial respiration, and the injection of atropine, are the best expedients. Emetics should be given if there is time. For Amyl Nitrite and Nitro-glycerin, 591, 594. Ammonia, cold affusion, and artificial respiration, strychnine and atropine subcuta- neously, also ergot, a true physiological antago- nist. For Aconite and Veratrum Viride, 597, 602. Ammonia, alcohol, artificial respiration, heat, atropine, or morphine, subcutaneously; also digitalis. For Muscarine, 612. A complete antagonism exists between atropine and muscarine; also, digitaline and eserine are antagonists. For Chlorine, 321. Ammonia for the gas, and albumen for the solution. For Carbolic Acid, 323. Saccharate of lime, or lime, is a chemical antidote. Oils and glycerin must not be given, but vegetable demulcents used freely. Atropine is a physiological antago- nist of great value. Emetics should be used, and diluents. For Salicylic Acid and Besorcin, 335, 346. Arterial and respiratory stimulants prevent the cardiac depression, especially atropine. For the Rydragogue Cathartics, 648. Demul- cents, opium, and stimulants. For Turpentine, 661. Emetics, diluents, and demulcents. Opium is the most important remedy to counteract the local irritation and the cerebral effects. For Savin and Cantharides, 681. Emetics and demulcents. Opium to counteract the depres- sion and local inflammation ; also, stimulants and atropine for the cardiac depression. I CLINICAL INDEX. 715 Antipyretics : Quinine, 177, first in importance, but must be given in full doses. Eucalyptus, 164, useful in chronic malarial poisoning. Digitalis, 425, chiefly useful as an adjunct to quinine. Sali- cylic Acid, or salicylates, 341, active and cer- tain antipyretics. Eesorcin, 348, Chinoline, Kairine, and Hydroquinone, 350, new and valuable agents to reduce fever- heat. Cold Baths, 66, 67, the most powerful means of lowering temperature. Pilocarpus, 568, re- duces fever after a preliminary stimulation. Of lesser importance are Aconite, 600, Gelsemium, 563, and Phytolacca, 611. Antiseptics : Carbolic Acid, 328, Salicylic Acid, 345, Boracic Acid, 352, Resorcin, 351, Quinine, 177, are the most important for the antiseptic method. Thymol, 357, Myrtol, 357, Oxygen, 319, Chlo- rine, 320, Bromine, 321, Sulphurous Acid, 221, etc., are of minor importance. Benzoates, 855. Sulphocarbolates, 332. Aphonia : Atropine, 435, is certain, nearly, in hysterical cases, if given to induce some obvious consti- tutional symptoms. Nitric Acid, 100, is very effective in the hoarseness of singers, when the aphonia is reflex from stomach disorder, and in fatigue of vocal cords. Electricity, 384, by an intra-laryngeal electrode, cures, usually, paresis of the vocal cords. Bismuth, 142, in powder directly to the ulcers. Coptis, 153, the infusion as a topical applica- tion. Chloride of Potassium, 192, probably the most effective remedy, locally, and by the stomach; full doses are necessary. Iodide of Potassium, 230, in solution, an excellent top- ical application. Quinine, 176, highly useful as a tonic. Muriatic Acid, 96, a local applica- tion to ulcers, formerly more employed than at present. Sulphurous Acid, 221, well diluted, in the form of spray. Carbolic Acid, 330, pure, applied to ulcers, an anaesthetic and alter- ant. Chlorine, 320. Apoplexy. (See Hemorrhage, Cerebral.) Arthritis, Chronic Rheumatic : Alkalies, 200, especially lithium.

Pilocarpine, 571, very service- able when given to produce free diaphoresis. Jalap, 643, in the form of the compound pow- der, most useful as a hydragogue cathartic. Elateriurn, 651, also a hydragogue of great power ; must be given cautiously, and not at all when gastro - intestinal irritation exists. Eemedies are more active when aided by a milk-diet, 46, or by dry diet, 41. Asthma : Air, compressed, 82. Oxygen, 319, pure or di- luted, by inhalation. Amyl Nitrite, 593, by in- halation, or Nitro-glycerin,596, by the stomach. Arsenic, 152, by the stomach, as a prophylactic, or by smoking in cigarettes. Bromides, 547, relieve in purely spasmodic asthma, but soon lose their effect. Chloral, 513, may arrest the paroxysms, but danger of chloral-habit. Chlo- roform, 492, by inhalation, dropped on warm water, relieves, but a habit is quickly formed. Last two remedies are dangerous in weak heart. Ether, 491, is safer and equally efficient by inhalation. Quebracho, 618, a new and valuable remedy in most forms of dyspnoeas Hyoscine, 451. Belladonna, 439, in pastile. with stramonium and other narcotics, gives temporary relief, but Atropine, hypodermatical- ly, is more efficient. Morphine, 535, and atro- pine subcutaneously, give more decided and lasting relief than any other remedies. Grin- delia, 609, is a most useful remedy, next in value as a means of immediate relief to mor- phine and atropine. Iodide of Potassium, 231, in full doses, succeeds remarkably in some cases. Ethyl Iodide, 239. Quinine, 183, as a tonic after the acute symptoms and as a pro- phylactic in the interval. Strychnine, 400, is indicated when there is weakness of respiratory muscles. Galvanization, 386, of the pneumo- gastric and cervical sympathetic relieves the spasmodic difficulty of breathing, and some- times effects a cure, and faradization of the chest-muscles has lately been reported success- ful in effecting a cure. Tartar Emetic, 2S6, and Lobelia, 584, carried to slight nausea in cases of deficient secretion of bronchial mucus. Pilocarpus, 571, in humid A. Astigmatism : Atropine, 442, a weak solution to facilitate exam- ination. Duboisine, 453, a substitute. Eserine, 578, in some cases.

Benzoate of Ammonia, 354, when urine is alkaline. Copaiba, 667, Cubebs, 669, Buchu, 676, Juniper, 672, and other urino-genitals, are useful, but liable to damage kidneys. Canthar- ides Tincture, 681, very efficient in small doses. Eucalyptus, 164, and Turpentine, 665, Quinine, 1S4, very beneficial when there is also prostatic disease. Bladder, Ikeitabilitt of : Belladonna, 441, of special utility in nocturnal incontinence, but must be carried to the pro- duction of physiological effects. Cantharides Tincture, 6S1, sometimes succeeds remarkably in irritable bladder of women. Aqua-punc- ture, 690, often curative. When urine is acid, Alkalies, 194; when alkaline, Benzoate of Am- monia, 354. Boils : Arsenic, 153, long continued for a succession of boils. Nitrate of Silver, 265, dissolved in nitrous ether, and painted on early to abort boils. Sulphides, 223, in small doses frequent- ly, either stop formation or terminate by ex- trusion of pus. Sulphurous Waters, 224, act in same way. Phosphates, 122, suitable tonics. Bone Diseases ; Softening of Bone : Carbonate and Phosphate of Lime, 121, 199, materials necessary. Phosphorus, 116, to pro- mote formation of bony tissue. Phosphates, 121, to improve tissue formation in general. Cod-liver Oil, 107, in combination. Chloride of Calcium, 199, in strumous subjects.

Cantharides, 681, Euca- lyptus, 164, and other urino-genitals, but are doubtful. Nitro- glycerin, 596, has had some remarkable successes. Beonchitis, Acute : Muscarine, 615, at the onset of the disease may arrest. Aconite, 600, in small dose frequently. Tartar Emetic, 2S6, in moderate quantity, with or without morphine. Nitric Acid dilute, 100, Cimicifuga, 433, an expectorant, may be combined with opium and aconite. Carbonate of Ammonia, 214, if secretion is viscid and there is depression. Sanguinaria, 314, and Lobelia, 5S5, nauseating expectorants, best given with opium. Morphine, or Dover's Powder, with quinine, 183, may abort if given early enough. Pilocarpus, 571, often highly useful at the beginning. For mild cases, Sirup of Squills, 676, or the compound sirup, 676, with Paregoric, makes a useful combination. Ipecac, 628, as expectorant. Bronchitis, Capillary : Iodides, 231, diminish the viscidity of the secre- tion, and thus lessen one of the chief dangers. Ethyl Iodide, 235. Carbonate of Ammonia, 214, acts similarly, and is indicated when de- pression comes on. Serpentaria, 161, a stimu- lating expectorant, may be given with ammo- nia. Turpentine, 665, when the capillary circulation languishes; Camphor, 457, also, under the same circumstances. Emetics are highly useful, the Subsulphate of Mercury, 620, Alum, 620, and Apomorphine, 622, being the principal. Pilocarpus, 571, when there is much secretion. Bronchitis, Chronic : Koumiss, 46, a valuable nutrient. Cod-liver Oil, 106. Iron, 132, especially the mistura ferri composita. Chloride of Ammonium, 214, combined with stimulating expectorants, as Eucalyptus, 164, or Serpentaria, 161, or San- guinaria, 314. The Iodides, 231, especially the iodide of ammonium, is serviceable in com- bination with the expectorants just named. Morphine, 533, or some preparation of opium, is indispensable to quiet cough. Strychnine, 401, and the sirup of the phosphate of iron, quinine, and strychnine, is a valuable respira- tory stimulant. Strychnine is the best remedy to check the reflex vomiting. Inhalations of Sulphurous Acid, in spray or gas, 221, of Car- CLINICAL INDEX. 717 boUc Acid, 327, and of the Benzoates, 354, are very useful.

To the remedies acting on the circulation may be added BaHum Chloride, 217, and Muscarine, 615, and under some cir- cumstances Ergot, 416, Quinine, 177, in full quantity, especially when combined with opium, may abort an incipient inflammation. Opium, 528, is the most important remedy in serous inflammation. Tartar Emetic, 286, affords undoubted good results in some forms, notably in acute bronchitis. Pilocarpus, 571, has very satisfactory results in exudation in the eye, pleura, etc. Insolation. (Sunstroke.) Cold Bath, 69, or douche or wet pack, for the state of high fever. Morphine, 531, hypoder- matically. Turpentine Enema, 664, as a de- rivative. Brandy, 477, and Ammonia, 213, for heat-exhaustion. Insomnia : Alcohol, 478, in the condition of cerebral anasmia, or in quantity to induce narcosis. Paralde- hyde, 486. Chloral, 512, the most direct and generally useful hypnotic. Belladonna, 440, in some morbid states with great restlessness and delirium; but Hyoscyamine, 409, Hyos- cine, 451, and Duboisine, 453, in sufficient quan- tity, are more frequently successful, especially in the insomnia of mania, puerperal mania, etc. Bromide of Potassium, 543, a direct hypnotic, but the action is easily prevented. Morphine, 530, is generally the best sleep-producer in cases of pain, in some kinds of mania, and in melan- cholia. Ewmulus, 538, a hop-pillow, has in- duced sleep; lupuline is more effective. Phos- phorus, 117, under some circumstances acts well. Galvanization, 3S1, of cervical sympa- thetic, causes sleep when circumstances are favorable. Water, 69, a tepid or warm bath at bed -hour, sometimes succeeds. Intermittent Fever: Cinchon a, ISO. Quinine is prophylactic; rightly used prevents malarial infection, and in proper quantity arrests the paroxysms. In severe cases, combination with morphine is very effec- tive. An attack impending may be arrested by Amyl Nitrite, 592, or Nitro-glyeerin, 596, as far as the chill ; but Pilocarpine, 571, hypo- dermatically, may bring on the sweating stage, thus preventing chill and fever. Chloroform, 493, by inhalation, or by the stomach in a full dose, may prevent a chill. Salicin, 334, Sali- cylic Acid, 342, and Jtesorcin, 349, especially the last named, have decided antiperiodic quali- ties only inferior to quinine. Carbolic Acid, 32S, hypodermatically, seems to be quite effec- tive. Apiol, Gil, also has very decided anti- periodic qualities. Salicylate of Cinchonidine, 16S, a recently introduced antiperiodic, is high- ly promising. Other substitutes for quinine are Nitric Acid, 99, which acts quite well in mild cases; Hydrastine, 166, which is very efficient, and probably next to quinine, if given in large doses; Eucalyptus, 164, more adapted to chronic malarial poisoning, and for convales- cence after attacks of fever; Oleoresin of Cap- sicum, 670, and Nux Vomica, 39S, adjuncts to other and more powerful remedies. Kairine, Chinoline, and Hydroquinone are recent sub- stitutes for quinine, 349. Intertrigo : Bismuth, 144, dusted over the surface. Zinc- Ointment, 282. Glycerite of Tannin, 303.

Mer- cury, 253, of great importance, as most cases CLINICAL INDEX. 727 are specific. Duboisine, 453, is much employed as a substitute for atropine. Jaundice : Aliment, 46, 52, especially the skim-milk cure, avoidance of fats, etc. Alkalies, 193, and the Alkaline Mineral- Waters, 205. Phosphate of Soda, 121, the most useful remedy in catarrh of bile-ducts, and in incipient sclerosis. Chloride of Ammonium, 213, and the Iodide, 230, are beneficial under the same circumstances. Man- ganese, 137, has unquestionable cholagogue effects, and stimulates the discharge of bile ; is adapted to the catarrhal form, and to the jaun- dice of gouty subjects. The resm-bearing ca- thartics, Rhubarb, Aloes, Podophyllum, Iris, and Euonymin, 637, promote the excretion of bile. Nitro- Muriatic Acid, 97, internally and by bath, has long had good repute in malarial jaundice. Mercurials, 251, are of doubtful util- ity, but good results seem to be obtained from small doses of calomel. Joints, Diseases of: Carbolic Acid, 329, in solution injected in syno- vitis, with reported good results. Galvanism, 3S6, highly useful in chronic affections. Mas- sage, 85, produces remarkable results in stiff- ness and deformity of joints from inflammation and lack of use.

Eserine, 578, lowers intraocular tension and relieves pain. Pilocar- pine, 571, is of great service in removing exu- dation and stopping inflammation. Zinc Sul- phate, 2S2, in solution, is an ordinary lotion in these cases, and is often prescribed with atro- pine. Lead lotions must be used with caution. Labor : Anaesthetics, 502 ; Chloral,-514, relieves pain and stops irregular action. Ergot, 417, is adminis- tered to hasten labor under suitable conditions, to cause expulsion of placenta, and to arrest haemorrhage. Morphine, 532, hypodermatical- ly, stops " false pains. 11 Lactation : Belladonna, 444. arrests the secretion of milk: a solution of atropine may be applied to the gland. Jaborandi, 572, increases secretion of milk. Phosphates, especially Phosphate of lime, 121, are highly useful in the debility of lacta- tion. Laryngismus Stridulus : Quinine, 184, administered in the interval, may prevent attacks that recur frequently. Nitro- glycerin, 596, will speedily allay the spasm. An Anesthetic, 501, will at once stop an attack ; a few drops of ether inhaled will usually suf- fice. Bromides, 547, will suspend attacks if a sufficient quantity is given, and prevent recur- rences. Tartar Emetic, 286, a nauseant, will stop the spasms, but may induce dangerous depression in young children. Subsulphate of Mercury, 620, is as effective and safer. Ipecac, 623, will also arrest attacks. Larynx, Diseases of : Aconite. 600, in acute catarrh, small dose of the tincture often administered.

Chlo- CLINICAL IXDEX. 731 roform, 498, in time to prevent the depression of the cold stage. Perspirations : Aromatic Sulphuric Acid, 100, is an ancient remedy, but in several respects objectionable. Atropine, 442, is one of the most useful reme- dies for " night-sweats," and locally applied for 6weats in various local situations. Picrotoxin, 407, a minute dose, will stop for several nights tbe sweats of consumption. Muscarine, 615, is also a serviceable remedy. For sweating of the feet, Salicylic Acid, 344, in powder, dust- ed over the feet and stockings, is probably the best remedy ; may also be used in lotion with borax. Permanganate of Potassa, 133, is an elegant toilet deodorant in fetid sweating of axillae and feet. Oxide of Zinc, 2S0, with ex- tract of belladonna in pill, is an ordinary reme- dy for night-sweats ; also Gallic Acid, 301. Phagedena : Bromine, 322, pure, applied with a glass rod, is a good escharotic, but not easily managed owing to its volatility.

Bensoate of Sodium, 355, in spray, has been proposed a a specific, and already discredited. Chloride of Calcium, 199, has had remarkably good effects in some cases. Cod-liver oil, 106, 107, is both a valuable food and a remedy; ether aids its digestion by increasing the pancreatic juice, and quiets the stomach. Mineral Acids, 100, especially nitro-muriatic in large doses, greatly improve the condition of some cases and retard the progress of the disease. Car- bolic Acid, 327, has been used with great advantage by inhalation to destroy the fetor of the expectoration, and to act on the local mor- bid process; systemically, the acid helps diges- tion and stimulates the assimilation. Creosote, 327, has been used with remarkable success recently. Phosphates and Hypophosphites, 122, Cuca, 470, with or without cod-liver oil, have good effects in the more chronic cases. Arsenic, 151, improves digestion and the for- mation of tissue, and increases the respiratory capacity. Strychnine, 401, checks the vomit- ing, and is a valuable respiratory stimulant.

Iodide of Potassium, 232, is useful to promote absorption of the exu- dation, and tincture of iodine or compound solu- tion injected to prevent reaccumulation of fluid. Quinine, 177, reduces temperature and checks exudation. Morphine, 529, is the most impor- tant remedy until exudations occur; quinine and morphine in sufficient quantity at the out- set may abort. Chloral, 512, is extremely use- ful when there are restlessness and delirium. Pilocarpus, 571, causes absorption of exuda- tion. Pneumonia : Aconite, 599, Teratrum Viride, 605, and Digi- talis, 426, very valuable antipyretics and anti- phlogistics for the stage of congestion.

Puerperal Fever : Quinine, 177. in large doses, first in importance. Opium, 529, when there are wakefulness and delirium, especially when local peritonitis ex- ists. Salicylic Acid, 341, and the Salicylates, Resorcin, 349, and Carbolic Acid, 328, 333, are remedies of great value. Turpentine, 663, when there is much tympanites or depression. Potassa Permanganate, 138, has been used with success internally. Puerperal Mania: Anaesthetics, 501, may be necessary in violent cases. Bromides, 544. will quiet, in cases with tendency to cerebral congestion. Chloral, 513, is a highly serviceable hypnotic, but its persist- ent use in anaemic cases is harmful. Duboisine, 453, and Hyoscyamine, 450, are probably the best hypnotics when there are much excite- ment and restlessness, as well as wakefulness. Chalybeates, 132, and Quinine, 179, are neces- sary when there is debility. Morphine, 530, under some circumstances is the best hypnotic. Puerperal Peritonitis : Opium, 529, is the most important remedy, and is probably curative. Quinine, 177, in consid- erable doses, is next in value ; a combination of quinine and morphine.

T.ENIJE: The various Tainiafuges, 653, Carbolic Acid, 327, Resorcin, 349, and Salicylic Acid, 340, have killed taenia, so that a purgative only was necessary. Turpentine, 663, is one of the most efficient remedies, although unpleasant in the highest degree. Ailanthus, 612, has suc- ceeded. Papain, S9, a digestive. Tetanus : Atropine, 443, injected into the rigid muscles, has done good. Strychnine, 399, is alleged to be curative in some cases, but doubts are proper. Chloral, 514, is certainly a remedy of great value. Amyl Nitrite, 593, has been used with success; Nitro- Glycerin, 596, should also be fairly tried. Gelsemium, 562, has succeeded, and is a promising remedy. Curara, 553, val- uable, but uncertain. Bromide of Potassium, 544, seems to be the most successful remedy. Physostigma, 576, has also been used with advantage in a number of cases, but its real value remains to be determined. Hyoscyamine, 450, or Duboisia, 453, may be used. Nicotine, 531, has effected a cure, but its use requires caution. Anaesthetics, 501, give temporary re- lief. Morphine, 536, injected into the tetanized muscles, gives great relief. Thermic Fever, or Sunstroke : Cold Baths, 69, for the hyperpyrexia. Morphine, 531, subcutaneously, when convulsions occur, or the insensibility and high temperature persist. Pilocarpine, 571, should be tried. Quinine, 178, Resorcin, 349, and other anti- pyretics should be administered subcutane- ously. Thrombosis and Embolism : Ammonia, 213, b} r the stomach or by intravenous injection, to liquefy the obstructing clot. Er- got, 415, Quinine, 179, and Digitalis, 424, for the collateral hyperemia and nedema. Tic-Douloukeux. (See Neuralgia.) Atropine and Morphine, 443, 535, these alkaloids in combination subcutaneously give relief. Croton-Chloral, 515, has special effects on the fifth nerve. Aconitine, 602, has lately been given with good results. Galvanism, 3S5, and Magnetism, 3S1, relieve the pain. Tinea : Boracic Acid, 352, is an excellent topical appli- cation. Mercury, 256, corrcsive sublimate, as an ointment or lotion for tinea tonsurans ; oleate of mercury in oleic acid, also, 258. Cop- per, 271, an ointment of the carbonate. Car- 736 CLINICAL INDEX. bolic Acid, 330, applied directly or in glycerin to the part affected. Sulphites, 222, in solu- tion, also useful. Sulphides, 224, sulphur-baths, 227, faithfully carried on, are curative. Tonsillitis : Aconite, 599, the tincture of the root, in cases accompanied by fever. Guaiacum, 310, a full dose is said to abort an attack. Ice, 64, held against the inflamed part, diminishes the con- gestion. Mercury. 250, small doses of calo- mel or gray powder reduce the inflammation. Quinine, 176, in a full dose at the outset may abort an attack. Alum, 295, in powder, solu- tion, or whey, does good after the acute symp- toms. Tincture of Iodine, 2j7, injected, will gradually diminish the hypertrophied tonsil. Toothache : Alum, 295, a solution in nitrous ether is said to be effectual. Tannin, 302, dissolved in ether, also relieves the pain of a carious tooth. Car- bonate of Soda, 201, a saturated solution held in the mouth relieves. Opium, 534, or mor- phine, a solution of. put in a carious cavity. Oil of Cloves, 35S, Carbolic Acid, 330, or Resor- cin, 349, put in a cavity stops the pain. Xan- thoxylum, 315, is a domestic remedy. Torticollis : Galvanism, 3S5, to the muscles in a state of spasm, and faradic applications to the antago- nist muscles in a paretic state. Massage, 85, Water, 76, hot douche. Tuberculosis : Grape-Cure, 42, Whey- Cure, 46, Cod-liver Oil, 106, Iron, 132, valuable in so far as it improves nutrition. Iodide of Iron and Manganese, 137. Chloride of Calcium, 199, apparently exercises a real curative influence. Typhlitis : Ice, 71, in form of a poultice to the seat of in- flammation. Opium, 529, in form of enemata of the tincture, or deodorized tincture by the stomach, or morphine subcutaneously. which is the most effective. leeches, 693, to the in- flamed region as soon as tenderness is mani- fest, and should not be omitted unless the sub- ject is feeble. Purgatives, 634, saline, especial- ly Epsom salts, alone admissible in typhlitis due to impaction of the caecum, and positively contraindicated in the other forms of the disease. Typhoid Fever. (See Fever.) Aliment, 49, a milk-diet, usually most suitable. Acids, Mineral, 99, the muriatic, has been much employed as a remedy to diminish fever and restrain diarrhoea. Iodine, 234, in the form of the compound tincture or solution, is a remedy of great value— lessens the violence and shortens the duration (German "Specific Treatment 1 '). Mercury, 253, calomel in ten- grain doses for several days during the first week or ten days — " specific treatment " — shortens the duration and moderates the vio- lence of the disease. Carbolic Acid, 328, and creosote have been used with great success ; may be administered with iodine advantageous- ly. Chlorine, 321. The antipyretic and antisep- tic treatment includes, besides the remedies just named, Quinine, 178, in large doses, Cold BatJis, 66, Salicylic Acid, 340, Resorcin, 346, Benzoate of Sodium, 355, Arnica, 564, and Digitalis, 425. Nitrate of Silver, 264, Bis- muth, 143, Fowler's Solution with Tincture of Opium, 155, are employed to restrain diar- rhoea. Ulcers : Nitric Acid, 101, a powerful escharotic, used to destroy unhealthy tissues and change the char- acter of the surface. I'otassa Chlorate, 201, in powder, applied to the surface, is remarkably beneficial in cases of unhealthy ulceration, in epithelioma, etc. Alum, 295, dried, is a feeble escharotic, and destroys unhealthy granula- tions. Zinc Sulphate, 281, dried, is a valuable caustic, and easily managed ; the chloride of zinc is more powerful and penetrating, as well as more painful. Potassa Fusa, 201, or the milder Vienna paste, diffuses widely and de- stroys deeply. Nitrate of Silver, 266, acts superficially, and is therefore to be used only when the mildest effects are necessary. Sul- phate of Copper, 271, is, like silver nitrate, a good application to change the character of an indolent ulcer, and to form a thin coating under which healing may proceed. Iodoform, 236, 243, in powder, dusted over the ulcer, is a capi- tal dressing for syphilitic ulcers, irritable sores, and superficial ulcers generally; its odor for these purposes may be covered by thymol, menthol, or eucalyptol. Carbolic Acid, 330, Salicylic Acid, 345, Boracic Acid,Sb2,Resor- cin, 349, Thymol, 357, Chlorine, 321, are anti- septic, deodorant, and alterative applications, of great value in wounds, unhealthy ulceration, and sloughing phagedaena Galvanism, 389, a galvanic couplet, will heal bed-sores and un- healthy ulcers. Uremia : Water, 65, the vapor-bath, and hot-water pack, to excite the skin and promote free diaphoresis. Pilocarpus, 571, Muscarme, 615, and Resor- cin, 349, active diaphoretics, especially the first named, but the state of the heart must be care- fully watched— a weak or fatty heart being a positive contraindication. Digitalis, 428, the infusion, an important means of procuring free action of the kidneys. Saline, 633, or Hydra- gogue Cathartics, 648, are of great importance to secure elimination by the intestinal canal, and to relieve the blood-pressure. Colchicum, 367, is an excellent hydragogue and derivative in these cases: is best when combined with other purgatives. Morphine, 530, hypodermat- ically, in full doses, is of remarkable value in uraemic convulsions. Cric-Acid Diathesis: Aliment, 53, the acid fruits and starchy foods are proper, but meats and other nitrogenous mate- rials objectionable. When excess of uric acid is due to deficient oxidation, Nitric Acid, 101, especially is of the greatest value; also muriatic and lactic acids. Alkalies, 194, the potash salts, particularly after meals ; also the Alka- line Waters, 205. Air, 81, Massage, 85. CLINICAL INDEX. 737 Urine, Incontinence of : Belladonna, 441, the most important remedy, and the alkaloid Atropine is the best prepara- tion, a quantity sufficient to induce its physio- logical effects being necessary. Ergot, 416, is effective when there is a paralytic sphincter, and in the case of diseased prostate. Iodide of Iron, 134, the sirup or official pill may be used ; it is successful in the case of pale, stru- mous, and feeble subjects. Strychnine, 399, may succeed when the other remedies fail; must be pushed, and is best adapted to cases characterized by great nerve mobility or weak- ness. When the urine is acid, a proper Diet, 42, and Alkalies, 194; when alkaline, the Bensoate of Ammonia, 354. Uterine Colic: Aquapuncture, 61 7, gives surprising relief. Mor- phine and Atropine, 535, subcutaneously. Camphor, 457, Gelsemium, 387, and the ano- dynes derivative from alcohol. Chloral, 514, Ether, 439, etc. Uterus, Firromata of : Ergotin, 416, subcutaneously and by stomach and rectum. Chloride of Gold, 259, persist- ently used. Chloride of Calciwm, 199, also taken for a long time. Saline and alterative Waters, 209 ; those of St. Catharine's, Canada, of Homburg and Kreutznach, etc. Iodine, tincture and glycerites, 237, applied topically. Electrolysis, 388. Uterus, Hypertrophy of ; also, S ub -Involution : ] Ergot, 414, 416, fluid extract, and Ergotin, sub- I cutaneously, must be persistently administered for a long time. Electricity, 386, Galvanism — an interrupted current, of great value in cases of simple enlargement. Iodoform, 236, and Iodo-Tannin, applied directly to the uterus, promote absorption. Chloride of Gold, 259, long continued in small doses, does much good. Phytolacca, 611, Digitalis, 424, and Cimici- fuga, 434, are very useful in sub-involution. Ipecacuanha, 627, has remarkably good effects in recent cases of sub-involution, with menor- rhagia or metrorrhagia. Uterus, Ulceration of : Hydrastis, 167, the fluid extract undiluted, freely applied, is a valuable application in cervicitis, endocervieitis, ulcer, and eversion. Iodo-Tan- nin, 236, iodoform and tannin packed around the cervix is a highly useful remedy in ulcer- ation and other disorders. Nitrate of Silver. 266, a long-used and highly esteemed topical remedy, but has been much abused. Carbolic Acid, 330, pure, on cotton-wrapped probe, is a safe and efficient application in endocervieitis, endometritis, and ulcerations. Vegetable As- tringents, 303, oak, heuchera, hamamelis, ru- bus, etc., in the form of strong decoctions, in- jections, or fluid extracts, undiluted. Glycerite of Tannin, 303, and Glycerin, 697, are useful in greater or less degree. Varicocele, and Varicose Veins : Ergot, 419, ergotin injected subcutaneously along- side the enlarged veins, an effective but painful expedient. The injection must not enter the 47 veins. Same expedient can be practiced in the case of any varicose veins in an accessible situ- ation. Variola : Water, 68, Cold Baths for fever, especially hyper- pyrexia. Quinine, 179, small doses as a tonic, full doses lor the suppuration, and antipyretic doses if the temperature is high. Ammonia Carbonate, 214, if there is manifest depres- sion, and especially during the suppuration stage. Chloral, 512, is highly useful and ne- cessary when there are high temperature, wake- fulness, and delirium. Opium, 529, for wake- fulness, low delirium, and adynamia. Carbolic Acid, 328, Besorcin, 349, Salicylic Acid, 341, and Bensoate of Sodium, 855, are from the theoretical standpoint valuable antiseptics and antipyretics. Iodine, 236, tincture, is applied to pustules to prevent pitting. Silver Nitrate, 266, a pointed stick of, is inserted into each pus- tule to abort it and thus prevent the formation of a cicatrix. Vomiting : Alcohol, 4S3, iced champagne or brandy in small quantity frequently, will sometimes arrest vom- iting of pregnancy, of sea-sickness, of cholera, yellow fever, etc. Ether, 489. Chloroform, 493, a few drops frequently, will arrest some kinds of vomiting, as sea-sickness, passage of gall- stones, etc. Bromides, 542, are serviceable in cerebral vomiting, and in cholera infantum in children, and in some cases of reflex vomiting. Chloral, 512. highly useful in vomiting of sea- sickness, cholera, and reflex vomiting. Ipecacu- anha, 625. rarely minute doses, will arrest some nervous and reflex attacks of vomiting. Arse- nic, 150, drop-doses of Fowler's solution, will stop vomiting of irritative dyspepsia, of ulcer, etc. Hydrocyanic Acid, 5S8, can be prescribed in the vomiting of acute stomach troubles. Pep- sin, 90, Milk and lime- Water, 199, Bismuth, 143, are proper in the vomiting of indigestion, of stomach inflammation, of acidity, and of acute intestinal disorders. Calomel, 250, very minute doses of, will stop vomiting in cholera infantum and in other intestinal disorders in children. Oxalate of Cerium, 288, is one of the numerous remedies for the vomiting of pregnancy. Nitrite of Amyl and Nitrogly- cerin, 596, are said to be very effective in the- vomiting of sea-sickness. Alkalies, 197, espe- cially the effervescent powder. Nux Vomica, 39S, the tincture, will sometimes succeed in, atonic states. Carbolic Acid, 326, has remark- ably sedative effects, and will arrest the vomit- ing of acute stomachal and intestinal disorders ; it is advantageously combined with bismuth in an emulsion. Oxygen, 319. Vomiting 07 Pregnancy: Cerium, 2S8, is a good remedy if given in full doses. Iodine, 230, a drop of the tincture, of the compound solution, or of the compound tincture, may succeed when other remedies fail. Carbolic Acid, 326, may succeed, but is uncertain, and its odor may excite disgust. Calumba, 159, a lew drops of the tincture may 738 CLINICAL INDEX. quiet the stomach quickly, but it often fails. Ingluvin, 87, has been frequently successful; also, Pepsin, 90, but is less useful than the for- mer. Nux Vomica, 398, a drop or two of the tincture may prove beneficial. Arsenic, 150, a drop of Fowler's solution, sometimes acts most favorably. Hydrocyanic Acid, 588, often does good and often fails. Alcohol, 483, as sparkling wine, may succeed temporarily. Oxygen, 319. Whooping-Cough : Atropine, 439, is a good remedy when secretion Is profuse, and in the spasmodic stage ; decided physiological effects should be produced to have any curative action. Hyoscine, 451. Bromides, 542, give relief to the spasmodic condition— to the whoop — but do not much moderate the violence of the disease ; Bromide of Camphor, 456, seems to be more useful. Hydrobromic ether, 490, subcutaneously by stomach, or by inhalation. Chloral, 512, is very useful at any stage, but is most serviceable during the spasmodic. Castanea, 301, a decoction of the leaves, may be taken at pleasure, and with cer- tainty of some, although not marked, benefit. Nitric Acid, 100, sometimes benefits exceed- ingly, but is uncertain. Alum, 294, especially when there is a copious bronchial secretion. Lobelia, 585, when it acts as a nauseant, is most beneficial. Carbolic Acid, 327, by in- halation, seems to be a very valuable remedy. Benzoate of Sodium, 356, internally and by spray, is reported to be very serviceable. To these may be added Salicylates, Resorcini and other antiseptics. Lactucarium, 538, the sirup, is a useful vehicle for the exhibition of other medicines. Asafoetida, 460, a disagree- able but useful remedy, and may. be given freely to infants and young children. Hydro- cyanic Acid, 588, may be given during the spasm stage, but it is most efficacious as a remedy for the cough kept up by habit after the subsidence of the disease, and the cough by imitation. Worms. (See Parasites.) Eucalyptus, 163. Calomel, 252, an excellent remedy to expel the round worm, and is best administered with santonin. Salicylic Acid, 340, has been used successfully against taenia. Anthelmintics, 654. Wounds : Lister's Method, 330, Water, 72, cold and hot, as a dressing for wounds, to arrest haemorrhage, and, in form of baths, to depress abnormal heat. Alcohol, 479, 484, an excellent antiseptic and astringent dressing, and as a remedy in pyrexia. Carbolic, 330, Boracic. 352, and Salicylic Acids, 345, used under the antiseptic system, to disinfect, deodorize, and to change the char- acter of wounds. Chlorine, 821. Writers Cramp : Metallotherapy, 292. Faradism, 385. Yellow Fever : Carbolic Acid, 329. Champagne, iced, 483. Turpentine, 663, for the vomiting.

With 170 Illustrations. 8vo. Cloth, $4.50. " M. Hospitalier distinguishes three sources of electricity, namely, the decomposition of metals or other decomposable bodies in acid or alkaline solutions, the transformation of heat into elec- trical energy, and lastly the conversion of work into current— giving rise to the three specific modes of force styled respectively galvanism, thermo-electricity, and dynamic electricity. He f rives a history of the progress of each, from the first crude constructions of the pioneer to the atest and most perfect form of battery, thus furnishing the student of science with a sufficiently copious text-book of the subject, while at the same time affording to the electrical engineer a valuable encyclopaedia of his profession. The work presents a most useful and thorough com- pendium of the principles and practice of electrical engineering, written as only an expert can write, to whom the abstruse by long study has become simple. The translator has acted the part of an editor also, and has added considerable material of value to the original text. His account of the Edison. Fox, and Brush systems of lighting, for example, is more complete than that of M. Hospitalier in his second edition. He has also added full descriptions of the fire-damp indi- cators of Liveling, Sourzee, and Mounier; of Bright's fire alarm and district telegraph, and of Dolbear's telephone, and Kelway's electric log:, together with other recent inventions not men- tioned in Hospitalier's treatise, exhaustive and excellent as it is." — New York Times. "To one who wishes to understand the rationale of electric science, and the methods by which the numerous results are accomplished, the work will be welcome."— Chicago Tribune. "The vast advance made within the past few years in electrical science gives great interest to a work as complete and authoritative as the one before us." — Cincinnati Daily Gazette. "A very stimulating and fascinating treatise." — Philadelphia Press. A PHYSICAL TREATISE ON ELECTRICITY AND MAGNETISM. By J. E. H. Gordon, B. A., Assistant Secretary of the British Association. 2 vols., 8vo, with about 200 full-page and other Illustrations. Cloth, $7.00. "There is certainly no hook in English— we think there is none in any other language— which covers quite the same ground. It records the most recent advances in the experimental treatment of electrical problems, it describes with minute carefulness the instruments and methods in use in physical laboratories, and is prodigal of beautifully executed diagrams and drawings made to scale." — London Times. "The fundamental point in the whole work is its perfect reflection of all that is best in the modern modes of regarding electric and magnetic forces, and in the modern methods of construct- ing electrical instruments." — Engineering. "Too great praise can not well be given to the description, illustration, and modes of using modern instruments."— Electrician. THE SPEAKING TELEPHONE, ELECTRIC LIGHT, AND OTHER RECENT ELECTRICAL INVENTIONS. By George B. Prescott. New edition, with 200 additional pages, including Illus- trated Description of all of Edison's Inventions. 214 Illustrations. 8vo. Cloth, $4.00. "Mr. Prescott's work on recent electrical inventions beins: American, is naturally largely occu- pied with the results of Mr. Edison's researches and the work of other distinguished Americans, though it is by no means limited to the results obtained on the other side of the Atlantic. It is a magnificently illustrated volume, and is the most complete history and discussion of telephones and allied instruments and the electric light which has come under our notice. It will probably remain a standard work until the progress of discovery leaves it behind, for every instrument of which it treats is explained so fully and illustrated so well that there is but little room left for improvement. For the student and all who have sufficient knowledge or interest in the subject, it will be a valuable magazine of information." — Westminster Review.

This magazine draws from the intellectual resources of all nations, and is now recog- nized as the most successful scientific periodical in the world. It is widely taken by the cultivators of science in all branches, particularly by physi- cians, who find it indispensable, and are extensively enumerated among its subscribers. The reason of this is, that our best minds are getting tired of the shallow frivolities of sensational literature, and demand a magazine that elevates the standard of popular reading in this country. Science is the great agency of improvement in this age, private and public, individual, social, professional, and industrial. In its irresistible progress it touches everywhere, and affects everybody. It gives law to the material interests of the community, and modifies its ideas, opinions, and beliefs, so that all have an interest in being informed of its advancement. Those, therefore, who desire to know what is going on in the world of thought in these stirring times, when new knowledge is rapidly extend ing, and old errors are giving way, will find that they can only keep posted by subscribing for The Popular Science Monthly. WHAT IS SAID OF IT. " This is one of the very best periodicals of its kind published in the world. Its corps of contributors comprise many of the ablest minds known to science and literature." — American Medical Journal, Si. Loais. " The Popular Science Monthly fills an unsupplied want. We can not well under- stand why an intelligent layman can dispense with it ; certainly this journal should be the monthly visitant of every physician and scientist." — Virginia Medical Monthly. "Each month it provides some one hundred and fifty pages of choice reading, often original, and always valuable, no less than invitingly interesting." — Saturday Evening Express, Boston, Mass. " The Monthly is a periodical that thoughtful readers will not willingly do without." — Louisville Courier-Journal. " Outside of medical journals, there is no periodical published in America as well worthy of being placed upon the physician's library-table and regularly read by him as The Popular Science Monthly." — St. Louis Clinical Record. " Every physician's table should bear this valuable monthly, which we believe to be one of the most interesting and instructive of the periodicals now published, and one which is destined to play a large part in the mental development of the laity of this country." — Canadian Journal of Medical Science. " This magazine is rapidly gaining in popular confidence and in circulation." — Brook- lyn (N. Y.) Union-Argus. " A journal of eminent value to the cause of popular education in this country." — New York Tribune. The volumes begin in May and November of each year. Subscriptions may begin at any time. Terms, $5.00 per annum ; single number, 50 cents. A club of five will be sent as directed for $20.00 per annum.
