    From tli6 results of eiglit attempts to produce favus ou the nou-hairy parts of adults with fungus of F. sulphureus- tardus the author concludes that this variety probably only excites on man a short-lived superficial disease, known as “ Favus herpeticus/^ The cheeks of the common house-mouse were inoculated with the three forms of fungus, and exhibited well the points of difference between the scutula which form in each case. Some of these distinguishing characteristics are as follows : Favus griseus.—Scutulum of moderate size, about that of a lentil, and as thick. On the upper surface flat or raised, not cup-shaped. Grey-yellow, like old wash-leather, neither shining nor smooth. Penetrated at all points by the fine and tactile hairs. Favus sulphureus-tardus.—Scutulum very large, covering the whole cheek, and thick. Cup-shaped on the surface, and covered by small humps, gathered into folds, yellowish white, cream-coloured, smooth as leather, shining in some parts, and pressing back the hairs, which do not penetrate it. Favus sulphureus-celerior.—Scutulum remains small, about the size of a peppercorn, cup-shaped on its surface, smooth but not shining; of a light ochre-colour towards its peri- phery, in the centre whiter, and on the folded margin of a horn-like brown. It presses back the finer hairs, but is penetrated by the larger. [A. E.]
