The Cavernous Ulcer is that the Entrance of which is streight and the bottom broad wherein there are many Holes fill'd with malignant _Sanies_, without any callosity or hardness in its sides. The Fistulous Ulcer is that which hath long, streight, and deep Holes, with much hardness in its sides; the _Sanies_ whereof is sometimes virulent, and sometimes not. The Cancerous Ulcer is large, having its Lips bloated, hard, and knotty, of a brown Colour, with thick Veins round about, full of a livid and blackish sort of Blood. In the bottom are divers round Cavities, which stink extremely, by reason of the ill Quality of the _Sanies_ that runs out from thence. _Are there no other kinds of Ulcers?_ {166} 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. _What are the Remedies proper to cleanse and dry up Ulcers?_ To this Purpose divers sorts of Liquors may be us'd, as also Powders and Plaisters: The Liquors are usually made of Briony-Roots, the greater Celandine, Lime, and Yellow Water; a Tincture of Myrrh, Aloes and Saffron, and Whey, whereto is added _Saccharum Saturni_; so that the Ulcers may be wash'd or bath'd with these Liquors; and very good Injections may be compounded of 'em. The Powders are those of Worm-eaten-Oak, Allom, and Cinoper, the last of these being us'd by burning it, to cause the Fume to be convey'd to the Ulcer thro' a Funnel. The Country People often make use of Potter's-Earth to dry up their Ulcers, with good {167} Success; but then they must must be of a Malignant Nature. The Plaisters are _Emplastrum de Betonica_, _Diasulphuris_, _Dessiccativum Rubrum_, and others; and the Ointments are such as these; Take three Yolks of Egg, half an Ounce of Honey, and a Glass of Wine, and make thereof a mundifying Ointment, according to Art: Otherwise, Take Lime well wash'd and dry'd several times, let it be mingled with the Oil of Line and _Bolus_, and it will make an excellent Ointment to mundifie and dry; a little _Mercury Precipitate_ may be intermixt (if you please) to augment the drying Quality; and _Mercurius Dulcis_ may be added in the Injections.
