"That animal food renders man strong and courageous, is fully disproved by the inhabitants of northern Europe and Asia, the Laplanders, Samoiedes, Ostiacs, Tungooses, Burats, and Kamtschadales, as well as by the Esquimaux in the northern, and the natives of Terra del Fuego in the southern extremity of America, which are the smallest, weakest, and least brave people of the globe, although they live almost entirely upon flesh, and that often raw.
"Vegetable diet is as little connected with weakness and cowardice, as that of animal matter is with physical force and courage. That men can be perfectly nourished, and their bodily and mental capabilities fully developed in any climate, by a diet purely vegetable, admits of abundant proof from experience. In the periods of their greatest simplicity, manliness, and bravery, the Greeks and Romans appear to have lived almost entirely on plain vegetable preparations. Indifferent bread, fruits, and other produce of the earth, are the chief nourishment of the modern Italians, and of the mass of the population in most countries in Europe. Of those more immediately known to ourselves, the Irish and Scotch may be mentioned, who are certainly not rendered weaker than their English fellow-subjects by their free use of vegetable aliment. The Negroes, whose great bodily powers are well known, feed chiefly on vegetable substances; and the same is the case with the South Sea Islanders, whose agility and strength were so great that the stoutest and most expert English sailors had no chance with them in wrestling and boxing."
The concession of Prof. L., which I have placed in italic, is sufficient for our purpose; we ask no more. Nevertheless, I am willing to hear his views of the indications afforded by our anatomical character, which are, as will be seen, equally decisive in favor of vegetable eating.
"Physiologists have usually represented that our species holds a middle rank, in the masticatory and digestive apparatus, between the flesh-eating and herbivorous animals—a statement which seems rather to have been deduced from what we have learned by experience on the subject, than to result from an actual comparison of men and animals.
"The teeth and jaws of men are, in all respects, much more similar to those of monkeys than of any other animal. The number is the same as in man, and the form so closely similar, that they might easily be mistaken for human. In most of them, except the ourang-outang, the canine teeth are much larger and stronger than in us; and so far, these animals have a more carnivorous character than man.
"Thus we find, that whether we consider the teeth and jaws, or the immediate instruments of digestion, the human structure closely resembles that of the simiæ (monkey race), all of which, in their natural state, are completely herbivorous. Man possesses a tolerably large cœcum, and a cellular colon; which I believe are not found in any herbivorous animal."
The ourang-outang naturally prefers fruits and nuts, as the professor himself shows by extracts from the statements of travelers and naturalists. He is also fond of bread. On board a ship or elsewhere, in confinement, he may, however, be taught, like men, to eat almost any thing;—not only to eat milk and suck eggs, but even to eat raw flesh.
It is true, indeed, after all these foregoing statements and concessions in regard to man's native character and the wholesomeness of a diet exclusively vegetable—and after admitting that the human body and mind can be fully and perfectly nourished and developed on it, this distinguished writer goes on to say that it is still doubtful which diet—animal, vegetable, or mixed—is on the whole most conducive to health, and strength—which is best calculated to avert or remove disease—whether errors in quantity or quality are most pernicious, etc. He says the solution of these and other analogous questions, can only be expected from experimental investigation. He proceeds to say—
"Mankind are so averse to relinquish their favorite indulgences, and to desert established habits, that we cannot entertain very sanguine expectations of any important discovery in this department. We must add to this, that there are many other causes affecting human health, besides diet. Before venturing to draw any inferences on a subject beset with so many obstacles, it would be necessary to observe the effects of a purely animal and a purely vegetable diet on several individuals of different habits, pursuits, and modes of life; to note their state, both bodily and mental; and to learn the condition of two or three generations fed in the same manner."
Now, the only difference between this opinion and what I conceive to be the truth in the case is, that just such experimental investigations as those to which he refers have, to all intents and purposes, been already made; as, I trust, will be distinctly shown in the sequel of this work.
