CHAP. 46.—VARIOUS KINDS OF DEPILATORIES.
Bats' blood has all the virtues of a depilatory: but if applied
to the cheeks of youths, it will not be found sufficiently efficacious, unless it is immediately followed up by an application
of verdigrease or hemlock-seed; this method having the effect
of entirely removing the hair, or at least reducing it to the
state of a fine down. It is generally thought, too, that bats'
brains are productive of a similar effect; there being two kinds
of these brains, the red and the white. Some persons mix
with the brains the blood and liver of the same animal: others,
again, boil down a viper in three semisextarii of oil, and, after
boning it, use it as a depilatory, first pulling out the hairs
that are wanted not to grow. The gall of a hedgehog is a
depilatory, more particularly if mixed with bats' brains and
goats' milk: the ashes, too, of a burnt hedgehog are used for a
similar purpose. If, after plucking out the hairs that arc
wanted not to grow, or if, before they make their appearance,
the parts are well rubbed with the milk of a bitch with her
first litter, no hairs will grow there. The same result is ensured, it is said, by using the blood of a tick taken from off a
dog, or else the blood or gall of a swallow.
(15.) Ants' eggs, they say, beaten up with flies, impart a
to the eyebrows. If it is considered desirable
that the colour of the infant's eyes should be black, the preg-
nant woman must eat a rat.2
Ashes of burnt earth-worms,
applied with oil, prevent the hair from turning white.
