covered to a large extent by peritoneum. It is attached to the liver at and lateral 
to the portal fissure, and to the crura of the diaphragm. Between these adhesions 
it is free and forms the ventral wall of the epiploic foramen. On the right side it 
extends backward beyond the caudate lobe of the liver between the layers of the 
mesoduodenum; here it is in contact with the upper part of the flank at the lumbo- 
costal angle, and is related dorsally to the right kidney and by its ventro-lateral

border to the retrograde part of the duodenum. The ventral or gastro-intestinal 
surface is in contact with the dorsal curvature of the rumen and the intestine. 
There is a deep notch (Incisura pancreatis) for the portal vein and hepatic artery, 
and several lymph glands are present here. The left extremity is small and quad- 
rilateral; it is related dorsally to the crus of the diaphragm, left adrenal, and the 
ceeliac and anterior mesenteric arteries, and is adherent ventrally to the rumen.
