Not illustrated. 1899 Excerpt: ...being highly vascular, play an important part in the nutrition of the epidermis and being also freely supplied with nerves they sustain an equally important relation to the sensitiveness of the skin. From the middle of fetal life onward, the fat-cells in the subcutaneous tissue increase in number to such extent that there is formed a continuous and well-marked subcutaneous layer of fat, the panniculus adiposus. Certain of the cells of the primitive corium differentiate into unstriated muscular tissue, forming thus the muscles of the hair-follicles, the arrectores pilorum, as well as the subcutaneous muscular tissue of the dartos of the scrotum and penis, and that of the nipple and of the perineum. The epidermis, consisting of the superficial horny layer and the deeper mucous layer or stratum Malpighii, is entirely an epithelial structure. Its elements are simply the descendants of the early ectodermic cells specially modified to afford the necessary protection to the more sensitive and delicate corium. The division into the two strata of the epidermis is indicated a early as the latter part of the first month, at which time the cells of the ectoderm have become arranged into two single layers, a superficial layer of rather large flattened cells and an underlying stratum of smaller elements. The cells of the outer layer, or epitrichium, which probably represents the future stratum corneum, successively undergo degeneration and desquamation, the places of those lost being supplied by the formation of new ones from the deeper layer. As time goes on, both layers increase in thickness and the hairs and the glands of the skin are gradually formed. With increased proliferation there is increasingly active desquamation of superficial cells, and as the degenerate an...
