I According to these writers the nerves, as they pass up from the under surfaceof the skin, become soft, flexuous, and capillary, and as they enter the villi on thetop of the papilli, lose their neurilema, and are expanded in the form of pulp. Theylook upon the changes which the nerve undergoes, and upon the derm, villi, andepidermic covering, as so many parts necessary to constitute the perfect organ oftouch : thereby assimilating it to the more complicated organs of sight and hear-ing.—Loc. cit. p. 1j, ct seq.—p. 33* 390 STRUCTURE OF THE SKIN Fig. 29.*. surface of the derm, and is there furnished with several layers ofthe epidermic horny matter, whichcover it like a hood. This horny co-vering is particularly thick at the heel,and serves to protect the papillae bydeadening shocks, and resisting the. pressure of the weight of the papillae are most numerous on thepalms of the hands and soles of thefeet, but are also scattered in otherparts of the Of the Sudoriferous or DiapnogenousApparatus. —This consists of a gland, see Fig. 28, p. 387, placed in thesubstance of the dermis, near its inner surface, into which agreat many capillary vessels run, and of a spiral duct which runsup through the horny layer sand opens obliquely through the outerepidermic crust by a slight depression or pore, on the back ofthe epidermic ridges, formed over the papillary bodies.
