    we occasionally see a true impetigo result, but I have never seen pustular eczema on a bald head; here it produces its ordinary clear secretion. Moreover, impetigo is seldom seen on the downy scalp of an infant. 4. Eczema of the lips.—This is a curious and somewhat rare form of superficial dermatitis, which used to be called psoriasis labiorum. Its true nature is shown by sero-purulent secretion being present, though in small quantity and forming very thin scabs, and by its association with eczema elsewhere, espe- cially with impetigo of the face. Thus, a little boy with this affection in its most marked form, had also a few pustules on the scalp and ordinary eczema of one ham. Its peculiar appearance is due to the thinness of the skin of the prolabium leading to haemorrhage, so that the crusts are brown or black and massive. It sometimes affects the lower lip alone. All the cases I have seen have been in children or young girls. The treatment I have found successful is removal of the crusts with bread poultices and application of our Unguentum metal- lorum.1 The patients are often pale and are benefited by steel. 5. Eczema rimosum, rubrum, squamosum, of the hands, including the so-called grocer’s and baker’s itch, and most cases of what has been called psoriasis palmaris. I have seen two or three cases of true psoriasis of the palms asso- ciated with ordinary unmistakable psoriasis, but I believe it never occurs independently. Such cases are either syphilis squamosa of the palms and soles, with its small, scanty, dirty scales, its dry surface, its symmetry, and its predilection for the inner side of the sole ; or else they are true eczema in its squamous stage. 6. Eczema of the anus, perinseum, vulva, or male genitals, extremely irritable, weeping, very rarely pustular. 7. Eczema of the outside of the forearm and legs. A form not uncommon in adults, usually rather acute in its onset, appearing in separate round patches, sometimes vesicular, more often presenting the appearance due to broken vesicles, which was described by Devergie as etat ponctue. Sometimes spread- ing to the thigh and upper arm, but rarely to the hand or foot j and rather avoiding the usual position of eczema at the elbow and ham. 1 Containing equal parts of Ung.
