of these, being killed with a spear by one who was on horse-back,
and its venom flowing on the spear, not only the man but the horse
also died. It spoils the wheat and not only that which it touches,
but where it breathes the grass dries and the stones are split.

THE WEASEL.

This beast finding the lair of the basilisk kills it with the smell
of its urine, and this smell, indeed, often kills the weasel itself.

THE CERASTES.

This has four movable little horns; so, when it wants to feed, it
hides under leaves all of its body except these little horns which,
as they move, seem to the birds to be some small worms at play. Then
they immediately swoop down to pick them and the Cerastes suddenly
twines round them and encircles and devours them.
