CHAP. 21.—ERETRIA.
Eretria takes its name from the territory [Note] which produces
it. Nicomachus [Note] and Parrhasius made use of it. In a medicinal
point of view, it is cooling and emollient. In a calcined
state, it promotes the cicatrization of wounds, is very useful
as a desiccative, and is particularly good for pains in the head,
and for the detection of internal suppurations. If the earth,
when applied [Note] with water, does not dry with rapidity, the
presence of purulent matter is apprehended.
