    figure. It is the largest of the flat bones, and forms the lateral and anterior part of the pelvis. It has two surfaces, the external or femoral, and the internal or abdominal surface. The external or femoral surface is of no great in- terest to the accoucheur ; superiorly and posteriorly it forms a wide fossa, convex above, concave be- low7, called the dorsum of the ilium, or sometimes the external iliac fossa. Downwards and forwards from this surface is the acetabulum or cotyloid cavity, in which the head of the femur is lodged. Before and below the cotyloid cavity, is observed the foramen ovale, called also the thyroid, or obturator foramen. This perforation is oval in the male, triangular in the female, though the angles are more or less round- ed off. At the upper edge of this hole posteriorly, there is a groove, in which the obturator vessels and nerves pass. In the recent subject the obturator fora- men is closed, except at the groove before spoken of, by a dense fibrous membrane, the obturator ligament. The internal or abdominal surface of the iliac bone, is at the upper part directed forwards, at the lower backwards ; at the upper and posterior part there is a rough, irregularly oval surface, corres- ponding with the lateral surface of the sacrum, to which it is articulated. The rest of the upper part of this surface is occupied by a wide cavity of no great depth, called the iliac fossa, or to distinguish it from the dorsum, the internal iliac fossa. It is limi- ted below, by a broad, and rounded prominent line, called linea ilio pectinea, which forms a part of the superior strait. Beneath this line is observed a
