The skull has sutures: one, of circular form, in the case of
women; in the case of men, as a general rule, three meeting at a
point. Instances have been known of a man's skull devoid of suture
altogether. In the skull the middle line, where the hair parts, is
called the crown or vertex. In some cases the parting is double;
that is to say, some men are double crowned, not in regard to the bony
skull, but in consequence of the double fall or set of the hair.
