These things belong to the class of apostemes, as we said when treating of them, and each receives its peculiar appellation from the substance contained in the tumour. Thus one of them is like fat, another like honey, and the third like pap. The indication of cure in them all is to discuss the contents, produce the putrefaction of them, or to cut them out. Some tumours fall under all these three indications of cure, namely, those which contain a thin fluid, as the meliceris; others come under two of them only, as the atheroma, for it can only be cured by excision or putrefaction. But the steotoma admits of no cure except by a surgical operation, for it can neither be discussed nor made to putrefy. The diagnosis of each of these may be found in the Surgical part of the work, while the materials of which the discutients are formed are mentioned under the head of scrofula. This application is peculiarly adapted for discussing meliceris: Twenty raisins without their stones; of squama æris, dr. iij; having first fomented, apply.—_Another_: Of Cretan cistus, of bdellium, of galbanum, of ammoniæ perfume, of bee-glue, of turpentine, equal parts; to be pounded together in a mortar. It applies to scrofula, parotis, furunculus, and phyma. But Archigenes applies to meliceris aphronitrum, and double the quantity of hellebore, with hard cerate. But septics cannot be applied while the skin remains entire; we must therefore in the first place lay bare the meliceris, atheroma, or strumæ, with caustic medicines, of which the most simple is that consisting of quicklime (calx viva,) soap, and strained lye. The following one is more complex, and admits of being kept: Of calx viva, dr. iv; of red natron toasted, of burnt lees of wine, of each, dr. ij; of vermilion, dr. j; triturate in lye; and having made it of the consistence of liquid honey, boil three times, until it is of the proper thickness, and lay it up in a leaden vessel, pouring in some lye, so that it may not quickly become dry. It applies to acrochordon, myrmecia, pterygium, clavus, callus, and excrescences of the gums. The lees of wine should not be older than two months. Anoint the skin with this, and when it begins to dry clean it away with a sponge, and anoint again; and when the skin becomes black, wash away again, and use escharotics. When the eschars fall off, apply the septic medicines. A septic application which is not irritating: Of squama æris, dr. iv; of realgar, dr. ij; of black hellebore, dr. ij; use with rose oil.—_Another_: Of squama æris, of realgar, of nettle seeds toasted, equal parts; use with rose oil.—_Another_: Of burnt sea-urchins, of the shell of the cuttle fish, of arsenic, equal parts; use with rose oil, but rub all the parts around with cerate and oil. This also is a good application: Of quicklime, p. ij; of chalcitis, p. j; of arsenic, p. j. * * * * * COMMENTARY. See most of the authorities referred to in the preceding section.
