What is a Cupping-Glass?
It is a Vessel or kind of Vial, made with Glass, the bottom whereof is somewhat broader than the top, which is apply'd to the Skin to cause an Attraction. There are two sorts of these Cupping-Glasses, viz, the Dry, and the Wet; the former are those that are laid upon the Skin without opening it; and the latter those that are apply'd with Scarification.
In what Diseases are Cupping-Glasses us'd?
In all kinds where it is necessary to make any Attraction; but more especially in Apoplexies, Vapours in Women, Palsies, and other Distempers of the like Nature. But the Applications of Cupping-Glasses are altogether different; for in Apoplexes they are generally set upon the Shoulders or upon the Coccyx; in Vapours upon the inside of the Thighs; and in Palsies upon the Paralytick Part it self.
What is a Leech?
It is an Animal like a little Worm which sucks the Blood, and is commonly apply'd to Children and weak Persons, to serve instead of Phlebotomy: Leeches are also us'd for the discharging of a Defluxion of Humours in any Part; as also in the Hæmorrhoidal Veins when they are too full; in the Varices and in several parts of the Face.
What choice ought to be made of Leeches?
It is requisite to take those that have their Backs greenish, and their Bellies red; as also to seek for 'em in a clear running Stream, and to cast away those that are black and hairy.
