THE LIVER, BY EWALD BERING. 



are here arranged in two opposite longitudinal rows. These 

 correspond to the openings of the lateral branches of the duct, 

 or in other words to the larger excretory ducts of the gland. 

 Minute punctiforin pores in or between the fossse lead into the 

 glands of the biliary ducts. 



The epithelium lining the glands of the hepatic ducts does 

 not present any peculiarity, but like that of the ducts into 

 which the glands open, is columnar ; and they may therefore 

 be regarded as eversions of the internal surface of the ducts, 

 especially since, in ducts of 0'2 millimeter in diameter, they 

 appear in the form of small and ultimately very slightly raised 

 projections. 



The smallest biliary ducts, arriving from different quarters 

 at the same hepatic lobule, do not anastomose with one another;

 which are the epithelial cells of the biliary ducts, to which, at the 

 lower part of the figures, the much larger hepatic cells suddenly 

 succeed. 



but those which accompany a particular interlobular vein 

 appear, in some instances, to do so around it, though this is a 

 point that requires further investigation. These ducts pass, 

 without material diminution of their calibre, into the intra- 

 lobular biliary canals or capillaries. The hepatic cells make
