The Human skull presents varieties related to sex, age, andrace. Those of sex are exemplified in the smaller size of the femaleskull, the more delicate proportions of the facial bones, the minorprominence of the malars, mentum, and angles of the jaw. In the skull of the child at birth, fig. 375, the jaws, through thenon-developement of the teeth and their sockets, are relativelysmaller than in the adult; but the facial angle, owing to the rapidgrowth of the brain, is, perhaps, nearer to the Greek ideal, at theperiod when the deciduous teeth are inplace: both the cerebral cavity and theorbits are then relatively greater.
