_The Extremities._—According to Huxley, there are three great divisions in the animal kingdom, as regards the extremities—viz. those which possess hoofs, those possessing claws, and those possessing hands. To the first division belong the herbivora and the omnivora. Almost all animals possessing claws are carnivorous, while animals possessing hands are almost invariably frugivorous. To this rule there are very few exceptions. Since man certainly belongs to the class possessed of hands, he is certainly frugivorous by nature. The reason for this becomes apparent when we stop to consider the habits of the various animals. The herbivora have no need for hands; they have merely to walk about the grassy plains, and partake of what nature has offered to them in abundance. The carnivorous animal, on the other hand, takes his food by violence—suddenly springing upon some defenceless and unresisting animal, and tearing it to pieces with its sharp teeth and claws. For this reason they are developed to the size and extent we see—capable of inflicting such terrible injuries. And here I would again call attention to what I said before—as to the carnivorous traits and characteristics of the cat as compared with those of the dog. The teeth and claws are far more developed in the former than in the latter. In man, of course, his teeth and claws are entirely unfitted for any such office. The soft, yielding nails are absolutely unlike the long, sharp claws of the carnivora: nothing could be more dissimilar. But if we compare the hands and extremities of man with those of other frugivorous animals, there is a very close similarity between them. The reason for this is that man (like the apes) can and should go out into the open fields and forests and pick his food off the trees. The human hand is eminently adapted to this end and for this purpose; but is quite _un_adapted for any such purposes as the claws of the carnivora are adapted for. I may remark here, incidentally, that all carnivorous animals _drink by lapping up the water_ or other liquid with their tongues; while man, and all vegetarian animals, _drink by suction_—by drawing up the fluid directly into the mouth. This is a very distinguishing characteristic, to which there are few if any exceptions. Needless to say, since man drinks by suction, he is eminently a vegetarian animal, and is quite distinct from the carnivora in _this_ respect, as in all others.
