The river Scamander also has the reputation of making
lambs yellow, and that is the reason, they say, why Homer designates
it the 'Yellow River.' Animals as a general rule have no hair on their
internal surfaces, and, in regard to their extremities, they have hair
on the upper, but not on the lower side.

The hare, or dasypod, is the only animal known to have hair inside
its mouth and underneath its feet. Further, the so-called mousewhale
instead of teeth has hairs in its mouth resembling pigs' bristles.
