504 DIGESTIVE SYSTEM OF THE DOG 
When hardened in situ, the gland presents the following characters: The 
parietal surface is strongly convex in conformity with the curvature of the dia- 
phragm and the adjacent part of the ventral wall of the abdomen, with which it is 
in contact. 
The visceral surface is in general concave, but is irregular in adaptation to the 
viscera in contact with it. The largest of these is the stomach, and the configuration 
of the liver varies greatly in accordance with the degree of fulness of that viscus. 
When the stomach is well filled, there is a ridge on the liver which corresponds to 
the lesser curvature. To the left of this is a large concavity adapted to the body 
and fundus of the stomach; and on the right is a smaller impression of the pyloric 
part of the stomach, the first part of the duodenum, and the anterior part of the

Left central lobe, gall-bladder, and great part of right central lobe not visible, 
right branch of the pancreas. Dorsal to the cavity for the pyloric part of the 
stomach is a deep depression, and at the bottom of this is the portal fissure. To 
see the latter the papillary and caudate lobes must be drawn apart. The hepatic 
artery enters the liver at the dorsal part of the fissure, the portal vein enters cen- 
trally, and the hepatic duct emerges at the ventral part. The gall-bladder is 
usually not visible till the right lateral and central lobes are drawn apart. 
When the stomach is empty and contracted, the visceral surface of the liver is strikingly 
different. There is then a shallow impression for the left part of the stomach on the left lobe 
and a large convex area, related to the small intestine and a mass of omentum. The pylorie and 
duodenal impressions are not much changed. 
The dorsal border presents a deep renal impression on its right part. The 
posterior vena cava passes ventrally and forward, at first in a deep groove on the 
-audate lobe, then largely embedded in the parietal surface of the right lateral lobe; 
it receives two or three large hepatic veins just before piercing the diaphragm.
