C. THE URINARY SYSTE]\[. 



Remove the liver, spleen, and intestines from the 

 abdomen, taldng care not to disturb the reprodjtctive 

 or the tn'iiiary organs. In removing the liver it 

 will prove most convenient to double-ligatiLre the large 

 inferior cava above and below the liver, and cut be- 

 tween the ligattircs. In removing the intestines double- 

 ligature the rectum as near the anus as possible, and 

 cut between the limturcs. 



I. The Kidneys are a pair of dark-red oval 

 bodies lying against the dorsal wall of the abdomen, 

 outside of the peritoneum. Each is usually im- 

 bedded in fat. If this is carefully removed, the Iiilus 

 will be exposed as a notch on the inner border where 

 the blood-vessels and ureter enter the kidney.
