But more than that, and worse still; the character of the internal structure of the tract is not alike in the two cases! In the carnivora, this is smooth, and offers but few impediments to the free passage of the food through it. In man, on the contrary, as with the higher apes and the herbivora, the intestine is corrugated or sacculated—this being for the express purpose of retaining the food as long as possible in the intestine, and until all possible nutriment has been abstracted from it. This is admirably suited to such foods as the herbivora and frugivora enjoy, but is quite unsuited for flesh-foods of all kinds—being, in fact, the worst possible receptacle for such foods. The intestine, in the carnivora, is suited for its particular food—it is short and smooth, and well adapted to dissolve the food quickly and pass it out of the system as rapidly as possible; while in frugivora, on the other hand, the intestine is adapted to retain the food a much longer time—the sacculated surface retaining the food as long as possible. The result of this is that, when flesh-foods are eaten, disastrous results are sure to follow.
