(Quasi capitis pi/us, the hair of the head,) also crinis. The hair. Capillus, though strictly the hair of the head, is used also for hair in general. The hairs are hollow, and furnished with vessels; are knotted at certain distances, like some sorts of grass, and send out branches at their joints. The disorder called plica polonica proves them to be hollow. The branching of the hair is visible at the extremities with a microscope, and the hair is apt to split if worn long and kept dry. Each of these hairs has a bulbous root of an oval shape, which is lodged in the skin. It has been supposed, that as long as any moisture remains about the roots of the hair it continues to grow, though the body be dead and mouldering to dust; but this is a popular superstition, wholly without foundation.
Dr. Cheyne observes, that the strength of the hair is proportional to that of the constitution.
