    upper border of this bone is called the crista or crest, having an external and internal labium. It gives origin to the oblique and transverse muscles of the abdomen. The anterior border has two processes: the anterior superior spinous process, from which the sartorius and tensor vaginte femoris muscles originate; and the anterior inferior spinous process, about an mch below the former, from which arises the rectus femoris. The outer part of the ilium bears the name of dorsum, and the inner of venter. From the former the glutei muscles originate, and from the latter the iliacus internus. Near to that part of the bone which joins the sacrum are the two posterior spinous pro- cesses. The ridge of bone which forms the front and lateral portions of the brim of the pelvis is termed linea inno- minata, or linea ileo-pectinea. [There are several points of obstetric interest con- nected with the ilium. The expanded portion or ala- of the female is broader than that of the male; but its width must not be taken as an invariable criterion of the capacity of the true pelvis. Cases occasionally occur in which great breadth of hip is associated with considerable narrowness of the pelvic cavity. If the al(B be too much expanded, the gravid uterus is insufficiently supported, and an increase of its na- tural obliquity is the result. If, on the other hand, they be too perpendicular, an opposite condition en- sues, and the womb is then apt, if the pelvis be un- usually capacious, to press injuriously on the subjacent viscera. — J.
