1 . These are the principal parts into which the whole body is divided: the head, neck, trunk, two arms, and two legs.  The whole cavity, from the neck to the pudenda, is called the trunk. That part of the head which is covered with hair is called the cranium, the forepart of this is called the sinciput. This is the last formed, being the last bone in the body which becomes hard; the hinder part is the occiput, and between the occiput and sinciput is the crown of the head. The brain is placed beneath the sinciput, and the occiput is empty; the cranium is a thin spherical bone covered with a skin without flesh. The skull has sutures: in women there is but one placed in a circle; men have generally three joined in one, and a man’s skull has been seen without any sutures at all. The middle and smooth part of the hair is called the crown of the head; in some persons this is double, for there are some people double-crowned, not from any formation of the bone, but only from the division of the hair.
