It sometimes happens, that the ulcerative action becomes converted into the inflammatory; the discharge diminishes, and sometimes ceases; the surface is red; and the edges and surrounding skin are elevated and inflamed. This, which has been called the phlogosis ulceris[68], strictly speaking, does not belong to the division of ulcers, because the ulcerative action is destroyed; but, as it is preceded, and very quickly followed by this action, and as the solution of continuity, and other external appearances continue, this affection may be allowed to rank as a genus amongst ulcers, in conformity to common language. [68] “Siccitas rubido et phlogosis ulceris facile cognoscuntur; dolore, pruritu, calore stipantur; ca impediunt carnis excrescentiam, adeoque indicant remedia emollientia,” &c. Sauvage Nosol. Meth. Tom. II. p. 613. When the pain and inflammation are considerable, leeches are frequently applied with utility in the vicinity of the sore; but it is more generally useful to apply warm poultices, which restore the secretory state, and the ulcerative action. GENUS V. _Of the Suppurating Ulcer._ This genus, like the last, accurately speaking, does not belong to the class of ulcers; but, as it is so intimately connected with it, both in its causes, and treatment, and appearances, it is of some practical utility to admit the arrangement. When an abscess is opened before the ulcerative action is induced, we have an open suppurating sore; but this is not the sore which is meant to be described here. The suppurating ulcer is, when simple, and independent of any specific action, most frequently only a high degree of the overacting ulcer; but, as its symptoms are somewhat different, and as it nearly resembles some specific sores, differing from these only in the absence of the peculiar action, resulting from the application of a poison, it may be proper to consider this as a separate genus. When the ulcerative action is very imperfectly carried on, which often arises from overaction, we find, that the organic particles are thrown out, not in the form of granulations, but in a more inorganic state, and lie upon the surface, mixed with the discharge from the other set of vessels. This has the appearance of very thick tough pus, and the sore which yields it may properly be considered to be in a suppurating state. This ulcer is distinguished by the pain which attends it, by a redness which surrounds the margin, and a hardened base, whilst the cavity of the ulcer is filled up with a thick straw-coloured substance, somewhat like lymph, which adheres firmly to the surface. This is improperly called a slough.
