Hepatic Ducts. — On the left side two main trunks arc 

 seen, the interval between them varying from 1-1.5 cm., 

 viz., a ventral one receiving brandies from the left mesial 

 and ventral part of the left lateral lobes — which latter 

 may be absent — and a dorsal branch from the left lateral 

 lobe. 



Dextrally, two main branches are also seen, viz., a 

 ventral one from the right mesial or cystic lobe, which 

 may be absent, and a dorsal one from the right lateral 

 lobe, which may receive branches from the right mesial 

 also. The right and left ventral hepatic ducts join the 

 cystic between the right mesial and thin part of the left 

 mesial, i.e., before reaching the portal fissure. The 

 right and left dorsal hepatic ducts join at the portal in- 

 terval. 



Com m o u Bile Duel. — This duct, formed by the junc- 

 tion of the cystic and hepatic ducts, passes with the he- 

 patic artery and portal vein (which is placed dorsally), 

 on the inner side of the light lat. lobe, and in front of the 

 spigelian projection from the right lobe, when that is 

 present. it is traced on the right of the gastro-hcpatic 

 omentum behind the pylorus and commencement of the 

 duodenum, and descends in the substance of the pancreas, 

 from which it has to be dissected — within the doudenal 

 loo}) — to finally terminate in the ascending limb of the 

 duodenum lying nearer to the duodeno-intest. flexure than 

 to the duodenal bend. It may even terminate just 

 proximal to the flexure. The width of the common duct 

 is .75 2m., and its length measures 9-10 cm., so that from 

 gall bladder to duodenum equals 14-16 en:. 



Pancreatic Duet. — A dissection of this structure on 

 the right side, where it is related to the common duct, is 

 at first associated with some little difficulty. Passing 

 from left to right it forms a bend, and is traced running
