The elephant,

by the way, is the least hairy of all quadrupeds.
With animals, as a general rule, the tail corresponds with the body as
regards thickness or thinness of hair-coating; that is, with animals
that have long tails, for some creatures have tails of altogether
insignificant size.
Camels have an exceptional organ wherein they differ from all
other animals, and that is the so-called 'hump' on their back. The
Bactrian camel differs from the Arabian; for the former has two
humps and the latter only one, though it has, by the way, a kind of
a hump below like the one above, on which, when it kneels, the
weight of the whole body rests.
