These fungi are capable of being implanted from oneanimal to another, from man to animals, and animals to man ;and Gruby tried the effects of the inoculation of the parasite onvegetables, and succeeded, by-inoculating the bark of an oak-tree, in getting a favus-cup identical with that which grows onthe heads of children. 736 DISEASES OF THE SKIN, Pathology.—The disease depends upon a cryptogamic fungus,named the aehorion Schonleinii, after Sehonlein, who was thefirst to suggest that the yellow crusts were constituted by avegetable parasite. The primary seat of the parasite is in the. Fig. 140. Fig. 141.
