Remove the liver, spleen, and intestines from theabdomen, taking care not to distitrb the reprodnctiveor the tirinary organs. In removing the liver itwill prove most convenient to doiible-ligature the largeinferior cava above and below the liver, and C2it be-tween the lio-atures. In removing the intestines dotible-ligattire the rectttm as near the anus as possible, andC2it between the lio-attires. I. The Kidneys are a pair of dark-red ovalbodies lying against the dorsal wall of the abdomen,outside of the peritoneum. Each is usually im-bedded in fat.
