No animal

of these genera is provided with double rows of
teeth. There is, however, an animal of the sort, if we are to
believe Ctesias. He assures us that the Indian wild beast called the
'martichoras' has a triple row of teeth in both upper and lower jaw;
that it is as big as a lion and equally hairy, and that its feet
resemble those of the lion; that it resembles man in its face and
ears; that its eyes are blue, and its colour vermilion; that its
tail is like that of the land-scorpion; that it has a sting in the
tail, and has the faculty of shooting off arrow-wise the spines that
are attached to the tail; that the sound of its voice is a something
between the sound of a pan-pipe and that of a trumpet; that it can run
as swiftly as deer, and that it is savage and a man-eater.

Man sheds his teeth, and so do other animals, as the horse, the
mule, and the ass. And man sheds his front teeth; but there is no
instance of an animal that sheds its molars. The pig sheds none of its
teeth at all.
