Excerpt from Vegetable Parasites, and the Diseases Caused by Their Growth Upon ManRingworm of the scalp is a frequent affection among children, and Often occurs upon the same individual and at the same time with ringworm of the general surface. The one may readily give rise to the other upon another person. In adults, however, it very rarely affects the scalp, and it may exist for months upon the hairy portions of the face, and extend from these parts over large portions of the body without appearing upon the head. Indeed, I have never seen but one adult thus affected, while the beard in gentlemen, as will be explained in another connection, is very frequently the seat of ordinary ringworm. Unlike favus, it is of more frequent occurrence in cities than in the country. It is in orphan asylums that it is most commonly found, and the introduction Of a child affected with it is Often the cause of an outbreak which may spread among scores of the inmates and last for months, before it can be exterminated. It causes some degree of itching, and, as just stated, occasionally a circumscribed in¿ammation sufficient to destroy the hair follicles, and thus produce partial baldness, but it does not affect the health in any way.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
