Excerpt from Elements of the Comparative Anatomy of the Vertebrate Animals: Designed Especially for the Use of Students The most common of the horny covering of the Mammalia occurs in the form of hairs. A distinction of these can be made, as in the feathers of birds, into woolly hairs corresponding to down, and ordi nary hair or fur. The first are very soft and slender, frequently curled, and are situated next the skin. The second kind are longer, stiffer, usually running to a fine point, and may be developed into bristles, vibrissae, and spines. The spinous hairs are mixed with the others; they are coarser, more rigid, and generally slender at the base, bulge out externally. The fine silken sort of hairs are the connecting link with wool. The roots, follicles, 'and stems of hairs, have the same structure in the mammiferous class of animals as in Man. The follicles of the hairs are, however, very large in the vibrissae of the upper lip and corners of the mouth in some Mammalia, as the Seal, Where they receive nervous twigs of consid ereble size.
