is in contact with the coils of the small intestine. The antero-

against the pubic bones, above which it is in contact with the

lateral surfaces are destitute of peritoneum, and are in contact

reflection from the lateral surface is raised to the level of
the obliterated hypogastric artery. The fundus undergoes little
alteration in position, being only slightly lowered. It
exhibits, however, a narrow triangular area, which is separated

peritoneum, and laterall
