About the time when the inferior extremities have become larger than the superior extremities, viz. the fifth month, the hair begins to make its appearance on the eye-brows and head. The male foetus may be distinguished from the female By the head being larger in proportion to the body,^I^5s rounded, the occipital protuberance greater, the crown of the head flatter, and the chest is more prominent than the umbilical region.
