These things will convince the devotee of the religion of vegetarianism that I am a lost soul, and always have been. Perhaps so. I try to guide my conduct by scientific knowledge; what I ask to know about the question of meat-eating is the actual facts of its effect upon the human organism--the amount of energy which it develops, the diseases which it causes, or, on the contrary, the immunity to disease which it claims to confer; also, of course, its cheapness and convenience as an article of diet. Some evidence of this sort we possess; but very little, it seems to me, in proportion to the importance of the subject. Professor Fisher has conducted some thorough experiments as to the influence of meat-eating upon endurance, which seem to develop the fact that vegetarians possess a far greater amount of endurance than meat-eaters. These experiments are what we want, but they seemed to me, when I read them, to be weak in one or two important particulars. They did not tell us what the vegetarians ate, nor what the meat-eaters ate. Those who are vegetarians at the present day are very apt to be people who have given some thought to the question of diet, and have attempted to adopt sounder ways of life; while, on the other hand, meat-eaters are generally people who have given no thought to the question of health at all--they are very apt to be smokers and drinkers as well as meat-eaters. Also it is to be pointed out that endurance is not the only factor of importance to our physical well-being. There have been numerous expositions of the greater liability of meat to contamination. Dr. Kellogg, for instance, has purchased specimens of meat in the butcher-shops, and has had them examined under the microscope, and has told us how many hundreds of millions of bacteria to the gram have been discovered. This argument has a tendency to appal one; I know it had great effect upon me for a long time, and I took elaborate pains to take into my system only those kinds of food which were sterilized, or practically so. This is the health regimen which is advocated by Professor Metchnikoff; one should eat only foods which have been thoroughly boiled and sterilized. I have come, in the course of time, to the conclusion that this way of living is suicidal, and that there is no way of destroying one's health more quickly. I think that the important question is, not how many bacteria there are in the food when you swallow it, but how many bacteria there come to be in food after it gets into your alimentary canal. The digestive juices are apparently able to take care of a very great number of germs; it is after the food has passed on down, and is lodged in the large intestine, that the real fermentation and putrefaction begin--and these count for more, in the question of health, than that which goes on in the butcher-shop or the refrigerator or the pantry.
