While the above was in press, I have met with the article, "_Gangrene de la bouche des enfans_," in the Dictionnaire de Medicine; written by M. MARJOLIN. The author in the Dictionnaire des Sciences Medicales, has given nothing material but references to some of the writers mentioned above; with one or two which were not within my reach. M. MARJOLIN has evidently identified the disease. He cites FABRICIUS HILDANUS, though we have not found a distinct account of it in that writer's works. He remarks that it is identical with the _necrosis infantilis_ of SAUVAGES. He also refers to SAVIARD, VAN SWEITEN, whom he justly mentions with the highest praise, UNDERWOOD, BERTHE, CAPDEVILLE, M. BARON, and the inaugural thesis of M. ISNARD. As we have no means of referring to the two last, we must judge of them by M. MARJOLIN'S statements. He observes the dissimilarity of BERTHE'S case. From the thesis of M. ISNARD, he gives us an account of the disease which corresponds very nearly, indeed, with that of VAN SWEITEN, and with the appearances observed at the Children's Asylum. "Almost all the infants affected with this disease in the hospitals of Paris," says M. MARJOLIN, "sink under it." He recommends, after VAN SWEITEN, the use of muriatic acid, which he mixes with honey in equal proportions. Thick sloughs he cuts away with a bistouri or with scissors. MM. JADELOT, GUERSENT, and BARON, have employed the actual cautery with success in several instances. M. MARJOLIN has cured three cases; one by the actual cautery, one by caustic potassa, and a third by _muriate of soda!_ which, he believes, will always destroy the foetor. It would be interesting, undoubtedly, to make repeated trials of this simple remedy; and we shall endeavour to do so in cases which admit of delay. FOOTNOTES: [1] Vol. I. p. 319, Anderson's edition.

[10] This name may be either from the ancient English or the low Dutch; if the one, by tradition, if the other, from the use of it by medical men. _Cancrum_ is an odd grammatical blunder; being, in reality, nothing but the accusative of Cancer, put instead of the nominative. The latter name was, as is well known, frequently applied by the older surgeons, in a vague manner, to any terrific and unmanageable ulcer; and, in particular, it was often applied to gangrene. The error appears to have been first made by Pearson, and copied by Mr. Cooper. Compare Muys and Vander Wiel, with Pearson, at the above references.
