Nevertheless, man, like some other animals, might live on vegetables; and flesh, which seems so analogous to flesh, is not a better nourishment than corn or bread; that which contributes to the nutrition, development, growth, and maintenance of the body, is not that visible matter which seems to be the texture of flesh or herbs, but of those organic particles which they both contain, since the ox, by eating grass, acquires as much flesh as either man or beast, that live on flesh and blood. The only real difference between these aliments is, that, in an equal quantity, flesh, corn and seeds, contain more organic particles than grass, leaves, roots, and other parts of plants; of which fact we may be certain by observing infusions of these different matters, insomuch that man, and other carnivorous animals, whose stomachs and intestines are not sufficiently capacious to admit a great quantity of aliment at once, cannot eat herbs enough to receive a quantify of organic particles sufficient for their nutrition; and it is for this reason that man, and those animals which have but one stomach, can only live on flesh and corn, which, in a small bulk, contains a great quantity of these organic and nutritive particles, while the ox[C], and other animals, that chew the cud, who have many stomachs, one of which is very capacious, and consequently can contain a large mass of herbage, can extract therefrom a sufficient quantity of these organic particles for their nourishment, growth, and multiplication; the quantity here compensates for the quality of the food, but the foundation is the same; it is the same matter, the same organic particles, which nourishes man, the ox, and all other animals. [C] The term ox is generally applied to cattle in general, but when used in its confined sense, we shall mark it with _Italics_.
