American_, “we think the evidence submitted shows that Dr. Salisbury has come nearer to the real intimate nature of consumption than Dr. Koch or any one we know. There is a simplicity, directness, breadth, and positiveness rarely seen in the treatment of a medical subject. Indeed, it is doubtful if there have been experiments so conclusive and extensive before or since.” It must be evident to even the crudest thinker that this fermenting process must ultimately produce the same effects when _begun in the stomach_, and described as indigestion; and no more efficient means of initiating this process can be imagined than that of swallowing indigestible substances——the most wholesome food-substances may be prepared in such a manner as to render them indigestible——or eating in excess of the needs of the organism, and therefore of the capacity for digestion. Thousands upon thousands of so-called healthy people are in this way approaching the point of decline, more or less slowly, but surely, utterly unconscious of their danger, simply because in their ignorance they can not recognize the premonitory symptoms, of which chronic constipation, for example, is one, and a very grave one. (See article on this subject.) [Footnote 28: Microscopic examination reveals the presence of a multiplicity of fatty crystals throughout the substance of the lungs of persons who have died of consumption. At a recent meeting of the New Orleans Pathological Society, its President, Dr. H. D. Schmidt, whose researches have been extended and minute, made an important microscopical demonstration to disprove Prof. Koch’s so-called discovery as to the bacilli of tuberculosis. Prof. Schmidt claimed to demonstrate that the so-called bacilli, thought by Dr. Koch to be the cause of consumption, were simply fatty crystals. Connecting with this the fact that Prof. Koch really found certain minute living organisms which he propagated artificially for several generations, it becomes evident to my mind (1) that the “bacillus” is simply a natural scavenger enveloped in the diseased tissue——the fatty crystal, or the tubercle——and (2) that its office is really, under the circumstances, conservative to life. Nor is this conclusion disproved by the alleged fact that the inoculation with the bacilli, of _supposably_ healthy animals, produced the disorder: In the first place, the little domestic pets, such as were thus operated upon, are always, owing to their artificial surroundings, predisposed to the disease in question, frequently falling victims to it without the aid of inoculation, and (3) this being the case, their inoculation with a liberal reinforcement of greedy vermin,——or, supposing that, as yet, none were generated, their premature introduction,——would naturally tend to a speedy and fatal termination. It makes no difference to a dead man whether his lungs were devoured by bacilli, or simply broken down from fatty
