CHAP. 31.—OSTRACITES; FOUR REMEDIES. AMIANTHUS; TWO REMEDIES.
The several varieties of ostracites[2699] bear a resemblance to shells. They are used by way of substitute for pumice-stone, for smoothing the skin. Taken in drink, they arrest discharges of blood; and, applied topically with honey, they are curative of ulcerations and pains in the mamillæ.
Amianthus[2700] resembles alumen[2701] in appearance, and suffers no diminution from the action of fire. This substance effectually counteracts all noxious spells, those wrought by magicians in particular.
