 hepatic duct, according to different observers.

 to commence in a plexus situated towards the circumference of the 

 lobule marked 6, &, called by Kiernan the biliary plexus. Within this 

 is seen the central part of the lobule, containing branches of the intra- 

 lobular vein. 



2. A small fragment of an hepatic lobule, of which the smallest 

 intercellular biliary ducts were filled with colouring matter during 

 life, highly magnified (from Chrzonszczewsky). 



3. View of some of the smallest biliary ducts illustrating Beale's 

 view of their relation to the biliary cells (from Kolliker after Beale), 5 - .
