CHAP. 30.—SORY: THREE REMEDIES.
The sory [Note] of Egypt is the most esteemed, being considered
much superior to that of Cyprus, Spain, and Africa; although
some prefer the sory from Cyprus for affections of the eyes.
But from whatever place it comes, the best is that which has
the strongest odour, and which, when triturated, becomes
greasy, black, and spongy. It is a substance so unpleasant to
the stomach, that some persons are made sick merely by its
smell. This is the case more particularly with the sory from
Egypt. That from other countries, by trituration, acquires
the lustre of misy, and is of a more gritty consistency. Held
in the mouth, and used as a collutory, it is good for toothache.
It is also useful for malignant ulcers of a serpiginous nature.
It is calcined upon charcoal, like chalcitis.
