. Natural history. For the use of schools and families. Zoology. 44 NATUEAL HISTOKT. the true Carnivora, with few exceptions, entirely sub- sist. 61. The animals of this order are readily distinguished from others by their teeth, which are formed for seizing, tearing, and cutting flesh, while tho?e animals that eat grains and grass have their principal teeth formed for grinding. In Fig. 24 you have a representation of one side of the jaws of a carniv- orous animal. The very long pointed teeth are called ca- nine teeth, because they are so observable in the dog. The teeth in rear of these are most- ly cutting teeth, the upper and lower going a little past each other so as to cut like '^'s- ^- scissors. Herbivorous (herb or vegetable eating) animals have grinding teeth in this rear part of the jaw. 68. The digestive organs of this order are conformed to the nature of then- food. As this is similar in quality to the substance of the animal itself, it does not require any complicated process to bring it into a fit state to nourish it. The stomach is therefore very simple and small, and the intestines are short;' while in the grain and grass eating animals the digestive apparatus is com- plicated and extensive, it requiring, ofCOurse, much ma- chinery to change into blood substances which are so un- like it as these articles of food are. I shall speak of this subject again when I come to the herbivorous Quadru- peds. 69. Some of the families of this order are not wholly carnivorous. And Just so far as any admit vegetable food into their diet we see a corresponding variation from the true carnivorous character of the teeth and the di- gestive organs. The teeth, for example, lose to a greater or less extent their tearing and cutting character..
