A strong infusion of _café noir_ (administered, it is to be presumed, to one not an habitual user) has been recently claimed by a celebrated French physician as an effectual antidote for the blood-poison that exists in typhus, typhoid, and yellow fevers. While this may be true, I am sure that there are, on the other hand, good grounds for the belief that the habitual use of coffee as an article of diet aids materially in the accumulation of the poison, and in the production of that abnormal condition or quality of the tissues of the body which the vital forces seek to rectify by means of the expulsive efforts which constitute the symptoms of typhoid and other fevers. Indeed, Dr. Segur, who evidently regards coffee as the nearest approach to the Elixir of Life, claims, as one of the _benefits_ resulting from its use, that “it lessens the waste of tissue, and therefore renders less food necessary.” Now, to interfere with or hinder any of the normal processes of the organism, especially those most vital to the economy, as, for example, that of the constant breaking down and excretion of the tissues, is not only to invite, but the impairment of these functions in and of itself constitutes, disease. He further says, “After a heavy meal, it relieves the sense of oppression and helps digestion.” What it really accomplishes, however, in such cases, is this: it mitigates the immediate effects of excess by diluting and washing away a portion of the food (of course unprepared for intestinal digestion), and, after the first congestive effects have subsided, by producing anæmia of the stomach, thereby _hindering_ digestion, it relieves temporarily, but at great cost ultimately, the sense of oppression produced by a gluttonous meal. By hindering digestion, in this or in any other manner, as, for example, by resuming muscular or mental labor directly after eating, we may prevent or delay plethora——the surcharge of the blood with nutritive material that results from the rapid absorption of an over-full meal;[87] but later on there will take place in the alimentary tract more or less fermentation of its undigested contents, which, with the foul and noxious gases generated thereby, will, to a greater or less degree, be absorbed into the circulation. Thus we observe the two-fold effect of this most delicious and seductive beverage: by “lessening the waste,” it prevents the body from remaining sound in its tissues, (see index: “fossil bodies”) and causes blood-poisoning from indigestion. For if, by reason of anæmia of the stomach and intestines, the digestive fluids are not secreted in sufficient amount to preserve it, “the food rapidly undergoes chemical decomposition in the alimentary canal, and often putrefies.”[88] This accounts for the gas coming from the stomach and bowels of persons troubled with indigestion and constipation, who frequently complain of a rotten-egg taste in the mouth. “This gas, in
