This process of inhalation and exudation has been termed by physiologists transpi­ ration, and should this function be impeded in its action by any means tending to block up the pores, illness would soon supervene, and that, too, of a dangerous nature. The influence which the skin exerts as a purifier of the system is known to every one; at the same time, a superficial consideration of its anatomy will not be out of place, as a detail of its cuticular arrangement will enable our readers to form their ownopinion upon the subject under notice. The skin consists of a dermis, or true skin, and an epideimis, or scarf skin.Within and beneath the true skin, two sets of glands are embedded, namely, the sudoiiparous and sebaceous glands 5the former are perspiratory organs, which excrete aqueous and gaseous materials, which escape fromthe skin through the medium of a duct, which terminates by a valve­ like aperture on the surface of the dermis ; the latter secrete apeculiar fatty substance, and are distributed over all parts of the body, but are more numerous in those parts largely supplied with hair, but have no existence on the palms of the hands or the plantar surfaces of the feet. The ductsof these glands open sometimes upon the cuticular surface, but more often into the hair-follicle, their function being to afford nourishment to the hair. The secretion of both sets of glands passes throughthe epidermis, which is com­ posed of tesselated epithelial cells, and serves a somewhat important part in permitting the quick
