Fig. 128.—Symbiotes equi.—(G-erlach.) According to Mr. Gamgee, who is translating from Gerlach,the finding of the various mites which constitute so essential afeature in mange, has as yet been attended with great diffi-culty, and the various procedures for their detection are asfollows:— (1.) Animals placed in the sun, and carefully examined;the acari (sarcoptes) do not get on the surface of the epidermicscales and on the hairs, as dermatodectes do ; and these can beseen with the naked eye. (2.) The sarcoptes are found below the scales or scabs,which may be so adherent to the skin that, on being removed,the latter may bleed. The dermatodectes are observed, afterthe animals have been exposed to the sun, on the outer partof these scales; but the sarcoptes are only seen on the scales examined should always be fresh, and they may belaid on black paper in a warm place in the sun, and thenexamined by a weak lens embracing a wide field of view. Thesmall sarcoptes are only dis
