THE CAT. 



[chap. VI. 



posterior surface of the riglit central lobe is marked by a depression in 

 which lies a pear-shaped bag — completely invested by peritoneum — 

 called the gall-bladder, which has its blind end (or fundus) 

 directed downwards near (r/b), the ventral margin of the liver. The 

 notch at which its fundus is situated, and the depression in which 

 the bladder lies, is called the q/stic fissure (cf). The fundus of 

 the gall-bladder is occasionally buried in the liver's substance, and 

 appears, through a cleft, in its convex surface. The part of the 

 right central lobe which lies to the left of the gall-bladder {re) is 

 itself bounded on the left by the umbilical fissure already described.

polygoual bases of tlie lobules. 



Beyond it lies a very small lobe, the left central lohe, which is 

 separated from a very large lobe — the left lateral lohe {II) — by a 

 deep fissure called the left lateral fissure {If). 



The bile, or hejmtic, ducts issue from the lobes of the liver and 

 the portal fissure, and join the duct which comes from the gall- 

 bladder. The latter duct is called the cystic duct, and the common 

 duct formed by its union with the hepatic ducts, is termed the 

 (htctvs communis clioledorJins {hd). This opens into the duodenum at 

 about an inch and a half fiom the pylorus — after being joined by 

 one of the pancreatic ducts.
