3rd. The _Ferae_ have generally six front teeth, of a somewhat conical
shape, both in the upper and under jaw: next to these, are strong and
sharp canine teeth; and the grinders are formed into conical, or pointed
processes. Their feet are divided into toes, which are armed with
sharp, hooked claws. This tribe is predacious, living almost entirely
upon animal food; and consists of the seal, dog, cat, weasel, otter,
bear, opossum, kangaroo, mole, shrew, and hedgehog genera.
4th. _Glires_ are furnished with two remarkably large and long front
teeth, both above and below, and are destitute of canine teeth. Their
feet have claws, and are formed both for bounding and running. They
feed on vegetables. The genera are, the porcupine, cavy, beaver, bat,
marmot, squirrel, dormouse, jerboa, and hare.
5th. The _Pecora_ have several blunt, wedge-like front teeth, in the
lower jaw, and none in the upper. Their feet are armed with cloven
hoofs. They live on vegetable food, and all ruminate, or chew the cud.
The genera are, the camel, musk, deer, giraffe, antelope, goat, sheep,
and cow.
6th. _Belluae_ have obtuse front teeth. The feet are armed with hoofs;
in some whole or rounded, in others obscurely lobed or sub-divided. They
live on vegetable food. The genera are, the horse, hippopotamus, tapir,
and hog.
7th. The _Cete_, or Whales, although they resemble fishes in external
appearance, are ranged very properly amongst the Mammalia, having warm
blood, similar lungs, teats, &c.
