TASMANIAN DEVIL. 



border. On its inner or right side are one, sometimes two 

 projections — the lower of which when two are present 

 is the larger. The projection is grooved, overlapping the 

 abdominal oesophagus before it reaches the stomach, and 

 on its inner side is the portal interval. Dorsal to the pro- 

 jection along the inner margin, we see a concavity for 

 the passage of the oesophagus. 



Mesial or Cystic Lobe. — Although the right lateral 

 and mesial lobes are practically one, yet a distinction can 

 be made between the two by the curved prolongation of 

 the right to the lumbar region, and a depression between 

 the two. It forms the anterior or ventral margin of the 

 liver. On this aspect the cystic lobe presents three por- 

 tions, viz., a large comparatively smooth left portion, on 

 the inner or light margin of which one or two fissures 

 and an upper and lower projection are noted, while on 

 the right we have two parts usually of almost equal size 

 separated by a fissure which may be distinct or not, and 

 so the cvstic lobe may be said to consist of a left, inter- 

 mediate, and right portions. In one the left lobe was sub- 

 divided also into two portions. Between the left and in- 

 termediate portions is the gap for the gall bladder, the 

 width of which at the ventral margin is 2 cm., and these 

 portions are hollowed for its reception. The intermediate 

 and right portions are characterised by their Assuring 

 and lobulation, and I have counted here no fewer than 11 

 lobules Between the two parts of the right portion on one 

 side and the left portion on the other we see the cystic 

 duct, which is joined by the hepatic ducts at the portal 

 interval. This interval is placed between the lower pro- 

 jection of the left cystic and the inner part of the left 

 lateral lobes on the left side and the internal part of right 

 cystic and right lateral on the right side.
