These intralobular capillaries converge toward the center of the 

 lobule and anastomose to form a capillary network, in the elon- 

 gated meshes of which are the columns of hepatic cells. These 

 capillaries approach the center of the lohule where they unite to 

 form the intralobular or central vein. The central vein frequently

 to form a single vessel which pursues its course through the axis 

 of the lobule. The central vein makes its exit at the periphery of 

 the lobule and enters the interlobular connective tissue where it 

 unites with its fellows to form larger sullobular veins. The sub-
