    101. Impetigo Scabida. Model of a leg, on which are several circular patches covered with thick crusts, from beneath which sero-purulent exudation is discharged ; in the popliteal space is a more diffused patch of impetigo sparsa; in the inter- mediate part are isolated pustules. 102. Impetigo Scabida. Model of the anterior part of the leg, on wliich is represented a circumscribed raw surface, partially covered with the thick scab of this form of impetigo. 103. Impetigo Scabida. Model of the foot and leg, affected with impetigo scabida, greatly swollen with disease of the sub- cutaneous cellular membrance ; it shows the remarkable fissured condition of the scab in this disease. 104. Impetigo Scabida. Model of the right foot of a child, showing several patches of thick fissured scabs, with an in- flamed circumference. The toes are in a state of inflammatory oedema, probably connected with some local irritating cause. 105. Impetigo. Model of the hands of a woman, showing the nails of distorted figure and morbid growth, the result of impetigo near the extremities of the fingers. PORRIGO. The observations of Schonlein, Remak, Gruby, &c., have shown that several of the forms of porrigo described by Willan and Bateman, are not pustular diseases, but consist of microscopic vegetable growth, in connection with the epithelium, the hair follicle, or the hair itself. Porrigo lupinosa, favus of French writers, belongs to the first, porrigo scutulata and porrigo furfurans to tlie second, and porrigo decalvans to the third. In porrigo lupinosa the growth consists of flexible tubes—some of which contain sporules and of sporules. The growth is situated in depressions of the skin, and commences in the epithelium (Gruby). Alopecia is produced by compression and atrophy of the hair bulb. The crusts are composed of sporules, molecular granules, and; of inter- lacing tubes or fibres. In porrigo scutulata the spores are formed in the interior of the follicles. Porrigo decalvans consists in the degeneration of the hair by a vegetable growth on the external part of the hair, in the form of branching filaments which bear sporules. 9
