Only two limbs; they are in front, short, flattened, appropriate for swimming, and display neither nails nor hoofs.

Seal Walrus

Dugong Manatee

Observation

This order is placed here only because of the relationship of the general form of the anmals which make it up. See my observations on p. 143.

THIRD ORDER: UNGULATE MAMMALS

Four limbs which are suitable only for moving; their digits are enclosed entirely at the ends by a horn which is called a hoof.

The family of quadrumanes is made up of the most perfect animals, above the last genera of this family.

The genus Orang (pithecus) ends the entire order, just as the monad began it.

What a difference in their organic structure and faculties!
