In some cases, the digestive fluids are weak and fermentation results, giving rise to flatulency and belching. An antiseptic, which may be prepared by mixing a teaspoonful of hydrochloric acid with four ounces of water, of which a teaspoonful may be taken after each meal, will prove beneficial to check the fermentation and aid digestion. The addition of one or two drops of a mixture of one part of carbolic acid and six of glycerine, to the above solution of hydrochloric acid improves its antiseptic properties. Or, Dr. Pierce's Golden Medical Discovery will stop undue fermentation, and from its tonic and invigorating effect upon the lining membranes of the stomach will generally overcome the indigestion. Some people are afraid to take it, when suffering from indigestion, because it has a sweet taste. But the sweet is not saccharine, or sugar sweet, but an entirely different sweet principle which prevents fermentation instead of promoting it.

Acidity of the stomach and the attendant irritation may be allayed by the following mixture: Calcined magnesia, one drachm; refined sugar, one drachm; subnitrate of bismuth, one-half drachm; oil of cajeput, ten drops. The dose is half a teaspoonful an hour after every meal. Any dispensing druggist can put it up.

It is frequently difficult to prevent the patient from over-distending the stomach, and thus impairing the tone of the muscular coats and prolonging the process of digestion.

In consequence of debility, over-exertion, anxiety, or chronic inflammation of the stomach, there is not a proper secretion, in quantity or quality, of digestive solvents, and it matters not whether it be a deficiency of the fluids of the stomach, or of the intestines, or of the pancreas and liver, the result is indigestion. The question of what important agent is lacking, naturally presents itself to the physician. Is it pepsin, the active principle of the gastric juice, which converts proteids into peptone, that is wanting, or is there a deficiency of pancreatin? Of course the principle which is lacking should be supplied; but has the physician the remedial agents properly prepared, and ready for prescribing? The specialist, having more cases of dyspepsia to treat than the general practitioner, is more likely to have the latest and most approved remedies applicable to loss of appetite, indigestion, impoverished blood, imperfect assimilation, and all diseases arising from faulty nutrition. In ordinary practice, the physician's time is divided in his consideration of acute, chronic, surgical, and obstetrical cases; in fact, much of it is occupied in riding to reach his patients. His attention is continually diverted from one class of cases to another, effectually preventing investigation in any particular direction. His patronage does not warrant him in the outlay of time required for the investigation of particular diseases, and the expense necessary to obtain the latest and best remedial agents for their treatment. In the multiplicity of his cares and arduous duties by night and by day, obstinate chronic cases become an annoyance to him, and whenever he can be otherwise professionally employed, he avoids them, disliking to undertake their treatment.

With plenty of time for scientific investigation, ample facilities to meet the demands upon his skill, and each succeeding case presenting some new phase, the treatment becomes a matter of absorbing interest to the specialist, and each success inspires greater confidence. We not only use in the treatment of indigestion, solvent remedies, like pepsin, which act only upon proteids, but also other remedies of recent discovery, which exert a remarkable curative influence in diseases of the digestive organs.

The chemistry of digestion and of life is becoming better understood. Any of the free acids may serve to dissolve a precipitated phosphate; but it is only the investigating therapeutist and experienced practitioner who understands which of them is the most and which is the least efficacious. Alkalies may dissolve lithic deposits, but who, unless he be an experienced physician, can detect the fault of nutrition which leads to their formation, or rightly interpret the symptoms indicating it? These simple illustrations of the complications which attend dyspepsia, are mentioned merely to show that they must be anticipated and taken into account in the treatment.

The number of cases of dyspeptic invalids treated by the staff of the Invalids' Hotel and Surgical Institute within file past few years, is so large as scarcely to be credited by those unacquainted with the prevalence of this disease. For this reason we have taken unusual pains to investigate the causes of the disease, and have spared no expense to provide the most approved digestive solvents, and stomachic tonics, which invigorate the mucous membrane of the stomach, and materially assist in reducing the food to a liquid condition. Some of these, without being purgative, increase the activity of the liver, and stimulate the intestinal secretions, two very important indications which should be fulfilled by remedies which cause no real depression. The recent important discoveries made in obtaining the active principles from indigenous plants, has opened the way to the use of a few of the most important of these remedial agents, hitherto almost wholly unknown to the medical profession, and the encouraging results attending our practice have amply repaid us for the investigation and originality in our treatment of this affection.

A careful chemical and microscopical examination of the urine often discloses the actual morbid conditions which perpetuate this functional disease.

CHRONIC DIARRHEA.

On account of the frequency and importance of chronic diarrhea, we deem it worthy of special consideration. It is frequently the sequel of the acute form of the affection. The urgent and severe symptoms of acute diarrhea are often abated, but the disease is not completely cured. The bowels are left in an irritable condition, perhaps in a state of chronic ulceration, which perpetuates morbid discharges.
