"But adults are not wholly exempted from this morbid affection, and it is not easy in all cases, to distinguish the cancrum oris from a cancerous or venereal ulcer in the mouth; since the uvula, tonsils or fauces may be the seat of each disease. I have seen ulcerations on the uvula and tonsils, with all the marks of a venereal sore, in patients where the presence of such a virus could not be suspected; and by treating them as canker of the mouth, they have been speedily cured. "The canker of the mouth ought to be distinguished from aphthae, the epulis and parulis, scurvy, cancerous ulcers, venereal ulcers and exulceration from the use of mercury. "_The mode of treatment._--It will be proper, "1. To remove the diseased teeth, bone, &c. if possible. "2. To prescribe a milk and vegetable diet, and to allow a prudent use of fermented liquors. "3. It will be adviseable to exhibit such remedies as, Peruvian bark; sarsaparilla; elm bark; mineral acids. "The external applications that I have generally found successful have consisted of such as the following: "_Preparations of copper_; a diluted mineral acid; burnt alum; decoction of bark with white vitriol; tincture of myrrh, &c."[2] Of the above articles, those which we have indicated by italics are omitted in the last edition of COOPER'S Dictionary; and, in a former one, they are directly prohibited with strong reprobation. Nevertheless, it is among these that we have found, beyond comparison, the most successful one. Mr. PEARSON prefixes to the preceding article a list of synonymes, with references to authors, in the manner of writers on natural history. They are as follow: _Aphthae Serpentes._--SENNERTUS; Medicina Practica. _Labrosulcium, seu Cheilocace._--ARNOLDUS BOOTIUS. _Oris Cancrum._--MUYS. STALPAART VANDER WIEL. _Gangraena Oris._--VAN SWEITEN. _Gangrene scorbutique des Gencives._--Auctores Gallici. Of these, SENNERTUS[3] merely mentions, under the article aphthae, that the latter sometimes spread around the fraenum and tongue, occasionally corroding the subjacent parts. He is so far from giving a clear description, under the head of Aphthae Serpentes, of any affection analogous to that we are about to record, that he quotes GALEN as remarking, very properly, that these are not aphthae at all, but putrid ulcers.
