“All that can be alleged in favour of flesh-eating because of its stimulating properties can be urged, and for precisely the same reasons, in favour of brandy-drinking or arsenic-eating.”[22] [22] “Scientific Basis of Vegetarianism,” pp. 23-24. There is nothing more certain than that the eating of meat, even if the meat be clean and wholesome, and the eating of it be not excessive, will in time produce grave results and diseases of the foulest and worst type. Not invariably, of course, but almost invariably. The rapid increase in uric acid which results from a flesh diet has previously been pointed out, and is now well known. In addition to this, there are numerous other poisons that are formed, or introduced into the body, as the result of flesh-eating—as Bouchard and others have proved conclusively. These poisons and their effects were carefully studied by Bouchard, and the results of his experiments are very interesting and convincing. He succeeded in isolating a number of poisons from the urea of flesh-eaters, and injecting them into animals, and noted the results. “One of the poisons in most minute doses produces death with violent spasms; another causes rapid fall of temperature until death occurs; another influences animal temperature in another direction; still another produces death with most profound coma.” The basis of the demonstration is this. The urine is really an extract from the tissues; the kidneys do not manufacture poisons _de novo_, but simply separate from the blood poisons found in solution therein, which have been washed by the blood-current from the tissues which it bathes in passing through the capillary network of systemic circulation. Bearing these facts in mind, Bouchard and his assistants injected into live rabbits certain known quantities of these poisons, and noted the results. Death invariably resulted—frequently in a very short time, and as the result of taking an extremely small dose of the poison. It was also found that, by increasing the amount of meat in the diet, the amount of these toxins could be increased accordingly, and proportionately; the greater the amount of meat consumed, the greater the amount of toxin given off by the animal in its urine, and the more deadly its effects. It was even found that a person living almost exclusively upon a flesh diet increased these toxins to fourfold the normal limit!
