The monkey,

as has been observed, is furnished with a tail. In
all such creatures the internal organs are found under dissection to
correspond to those of man.

So much then for the properties of the organs of such animals
as bring forth their young into the world alive.

Oviparous and blooded quadrupeds-and, by the way, no terrestrial
blooded animal is oviparous unless it is quadrupedal or is devoid of
feet altogether-are furnished with a head, a neck, a back, upper and
under parts, the front legs and hind legs, and the part analogous to
the chest, all as in the case of viviparous quadrupeds, and with a
tail, usually large, in exceptional cases small. And all these
creatures are many-toed, and the several toes are cloven apart.
Furthermore, they all have the ordinary organs of sensation, including
a tongue, with the exception of the Egyptian crocodile.
