LIVER IN WOMBAT. 



(PHASCOLOMYS.) 



The liver extends to the left beA^ond the mid line, and 

 is found in the epigastric and right and left hypochon- 

 driac region. 



Diaphragmatic Surf (tee. — Left Lateral Lobe. — 

 Specimen A. — Mewed from this aspect we are struck by 

 the large relative size of the left lateral lobe, i.e., the por- 

 tion to the left of the mesial or "suspensory'' ligament. 

 The right margin of the liver is seen to be larger than 

 the left, and the dorsal than the ventral. Though the liver 

 of the Wombat is approaching the human, and unifica- 

 tion of the hepatic lobes is becoming the type, yet we can 

 — though much less distinctly than in other Marsupials — 

 define a left lateral — right lateral — and mesial or cystic 

 lobes. In this adult the left lateral lobe measured 17 cm. 

 dorso-ventrally, and 13 cm. laterally. On the inner side 

 dorsally a concavity is noted for the passage of the oeso- 

 phagus. Between this lobe and the mesial or cystic is a 

 fissure about 3.5 cm. long, and between its dorsal ex- 

 tremity and the inf. v. cava is 2 cm. of hepatic tissue, so 

 that these lobes are becoming linked up, only the suspen- 

 sory ligament passing between the fissure and the inf. 

 vena cava. To the left of this fissure, i.e., on the left lat. 

 lobe, another complete, though small, fissure is seen only 

 1.5 cm. long, and between these two fissures is a portion of 

 hepatic substance, measuring 1 .5 cm. laterally. It repre- 

 sents the left cystic of other Marsupials, and the fissure is
