A little reflection will convince any one, that in such a system as exists in the world, this universal decay and dissolution are indispensable. For dead organic matter is essential to the support and nourishment of living beings. Admit, for the sake of the argument, (although it is obviously absurd in respect to the carnivorous races,) that animals might be supported by vegetable food. Yet, if plants must furnish nourishment for their successors, as well as for animals, the organic matter must at length be exhausted. And, furthermore, how could animals feed on plants without destroying, as they now do, multitudes of minute insects and animalcules? It is obvious, also, that, for a variety of reasons, the multiplication of animals must soon be arrested, or famine would be the result, or the world would be more than full. In short, it would require an entirely different system in nature from the present, in order to exclude death from the world. To the existing system it is as essential as gravitation, and apparently just as much a law of nature. To strengthen this argument still further, comparative anatomy testifies that large classes of animals have a structure evidently intended to enable them to feed on other tribes. The teeth of the more perfect carnivorous animals are adapted for seizing and tearing their prey, while those which feed on vegetables have cutting and grinding teeth, but not the canine. So the whole digestive apparatus in the carnivora is more simple, and of less extent, than in the herbivorous tribes, while in the former the gastric juice acts more readily upon flesh, and in the latter upon vegetables. The muscular apparatus, also, is developed in greater power in the former than in the latter, especially in the neck and fore paw. Throughout all the classes of animals, those which feed on flesh are armed with poisonous fangs, or talons, or beaks, or other formidable weapons, while the vegetable feeders are usually in a great measure defenceless. In short, in the one class we find a perfect adaptation, in all the organs, for destroying, digesting, and assimilating other animals, and in the other class, an arrangement, equally obvious, for procuring and digesting vegetables. Indeed, you need only show the anatomist the skeleton, or even a very small part of the skeleton, of an unknown animal, to enable him, in most cases, to decide, what is the food of that animal, with almost as much certainty as if he had for years observed its habits. Who can doubt, then, that when a carnivorous animal employs the weapons with which nature has furnished it for the destruction of another animal, in order to satisfy its hunger, that it acts in obedience to a law of its being, originally impressed upon its constitution by the Creator? It is true, that even the flesh-eating animals may be taught for a time to subsist upon vegetable products. But this is unnatural; and such an
