    e. Another patch in which the centre is cleared to a greater extent, and a part of the margin has also subsided. This is a further advance towards cure. f. Another patch, exhibiting a more advanced stage of the curative movement. g. Alphos vulgaris, as it affects the convexity of the elbow; the drawing is made from the same patient as a. In this situation the patches are generally confluent, and lose their circular figure. h. Alphos diffusus (page 403), with deep chaps on the morbid skin. The drawing was made from a patch situated on the back of the hand. i. This figure, if the patch were no larger than represented in the drawing, would be an illustration of alphos diffusus ; if, however, it extended over a considerable portion of a limb, it would be termed alphos inveteratus. It is intended to illustate the latter disease. k. Syphiloderma palmare (page 540). The irregular margin of thickened epidermis and the chaps are characteristic. This is clearly an erythema. l. A portion of a patch of chronic eczema (eczema furfuraceum vel squamosum), in its dry state, from the nape of the neck. The disease covered the whole of the back of the neck, the scalp, the chest, and the shoulders. Plate 13. LUPUS NON EXEDENS. An example of this obstinate disease which has existed for thirty-three years. The tuberculated and salmon-coloured margin of the patch, its variegated area streaked with white and cicatrix-looking lines, and the erosion of the border of the ala nasi, are characteristic of this disease (page 422). Plate 14. DISE ASES OF THE SEBIFEROUS FOLLICLES, HAIR-FOLLICLES, AND HAIRS. ACNE. GUTTA ROSACEA. SYCOSIS. FAVUS. TRICHONOSTS. A. Acne vulgaris punctata (page 805). Several groups of the pimples of this eruption, in their early state. They are characterised by the black point which is perceived in the centre of each. b. Acne punctata in a more advanced stage ; they are now becoming slightly inflamed. c. Comedones (page 780). These black spots on the skin, caused by inspissa- tion of the sebaceous substance and discoloration of the external end of the small piles so produced, generally accompany the development of acne. They frequently precede the form A, the pimples of acne punctata being comedones with elevation and induration of the skin immediately around their apertures. d. Acne vulgaris (page 805). Conical elevations with inflamed bases, and suppurating at the summit. C
