In regard to the intestinalcanal, we find, that man holdsa medium place between thecarnivorous and herbivorousanimal, although approximat-ing more to the latter. Inthe carnivorous—for reasonshereafter mentioned—it is un-necessary that the food shouldremain long; accordingly, thecanal is very short. In theherbivora, on the other hand,and for opposite reasons, thecanal is long, and there isgenerally a large caecum anda pouched colon.
