Not illustrated. 1869 Excerpt: ... become, like their predecessors, flattened and scale-like (fig. 102). It is by this process of production from beneath, to make up for the waste at the surface, that the growth of the cuticle is effected. The thickness of the epidermis on different portions of the skin is directly proportioned to the friction, pressure, and other sources of injury to which it is exposed; and the more it is subjected to such injury, within certain limits, Fig. 102. Skin of the negro, in a vertical section, magnified 250 diameters, a, a, cutaneous papilhe; b, undermost and dark coloured layer of oblong vertical epidcnuis-eells; c, mucous or Malpighian layer; d, horny layer (from Sharpey). the more does it grow, and the thicker and more horny does it become; for it serves as well to protect the sensitive and vascular cutis from injury from without, as to limit the evaporation of fluid from the blood-vessels. The adaptation of the epidermis to the latter purposes may be well shown by exposing to the air two dead hands or feet, of which one has its epidermis perfect, and the other is deprived of it; in a day, the skin of the latter will become brown, dry, and horn-like, while that of the former will almost retain its natural moisture. Cutis vera.--The corium or cutis, which rests upon a layer of adipose and cellular tissue of varying thickness, is a dense and tough, but yielding and highly elastic structure, composed of fasciculi of fibro-cellular tissue, interwoven in all directions, and forming, by their interlacements, numerous spaces or areolae. These areola are large in the deeper layers of the cutis, and are there usually filled with little masses of fat (fig. 105): but, in the more superficial parts, they are exceedingly small or entirely obliterated. By means of its tou...
