The manner of curing both is the same; but the greater disease requires the sharper remedy. And the regimen must first be regulated; the patient must rest in his bed, for some days abstain from food, drink water very plentifully, and have a clyster given him. Then, when the inflammation is gone, let him take food of a good juice(81), avoiding every thing acrid; he may drink as much as he will, provided he be content in the day-time with water but at supper, he may also drink some rough wine. But the abstinence should not be equally severe in a herpes, and a therioma. This then is the regimen necessary. Externally upon the ulcer, must be sprinkled powder of dry aloes, and if that does but little service, chalcitis. But if any nerve, by the flesh being destroyed, be laid bare, it must be covered first with linen, lest it be burnt by that medicine. If there is need of remedies still more powerful, we must make use of those compositions, that cauterize more strongly. Now when any medicine is sprinkled on, it ought to be done by the broad end of a probe(82). Over it should be applied either lint with honey, or olive leaves boiled in wine, or horehound: and these must be covered with linen dipped in cold water, and then well squeezed. And all round, where there is a tumour from the inflammation, repellent cataplasms must be applied. If by these methods it grows no better, the place ought to be cauterized with a _hot_ iron; the nerves that are in view being first covered. By what has been said on other occasions, it will be clear enough to any body, that a part, which is burned either by medicines or the actual cautery, must first be cleansed, and then filled up. [Sidenote: _Of the ignis sacer._] The ignis sacer ought also to be numbered amongst bad ulcers. There are two species of it. The one is of a colour inclining to ruddy, or a mixture of red and pale, and the surface is roughened by contiguous pustules, of which no one is bigger than another, but they are very numerous, and exceeding small. In these there is almost always pus, and often a redness attended with heat; and that spreads, sometimes when the part first affected is healing, sometimes when it is ulcerated, in which case, the pustules breaking, one continued ulcer is formed, discharging a humour, which seems to be betwixt sanies and pus. It attacks chiefly the breast, or sides, or extremities, and particularly the soles of the feet. The other kind comes with an ulceration in the surface of the skin, but without going deep, broad, inclining to a livid colour, but unequal; and the middle part of it heals, while the extremities spread; and often that, which seemed to be sound, ulcerates again. But the skin round about it, which is to receive the disease, grows tumid, and hardish, and the colour of it is a blackish red. And this disease too generally attacks old people, or those, that are in a bad habit, but chiefly in their legs.
