Are there no other kinds of Ulcers?
Yes, there are also Verminous, Chironian, Telephian, Pocky, Scorbutick, and others, which have much affinity with, and may well be reckon'd among the five Kinds already specify'd.
What are the means to be us'd in the curing of Ulcers?
Ulcers ought to be well mundify'd, dry'd and cicatriz'd; but with respect to the several Causes and Accidents that render 'em obstinate, and difficult to be cur'd, it is also requisite to make use of internal Medicines, which may restrain and consume 'em. If their sides grow callous, they are to be scarify'd, in order to bring 'em to Suppuration; and if there be any Excrescences, they must be eaten away with corroding Powders, such as that of Allom; or by the Infernal Cautery.
