THE BILIARY CANALS OF THE LOBULES.

giving the impression that the cell substance adjoining the 

 biliary ducts has become stained with bile. In similar cases it 

 may be shown that by far the greater number of the biliary 

 ducts run between the planes of junction of adjoining cells, and 

 but seldom along the borders. It is observable that when the

Fig. 122. From the liver of a child three months old, hardened 

 in chromic acid. The hepatic cells with their single nuclei are sepa- 

 rated from the capillary wall by a small intervening space. The 

 capillaries contain closely compressed coloured, and a few colourless, 

 blood corpuscles. A few elongated nuclei belonging to the capillary 

 wall are seen. Within the line of junction (septum) between two hepatic 

 cells the transverse section of a biliary duct is seen as a small trans- 

 parent space. There is also one at the angle where several of these 

 cells come into contact. 



hepatic cells are arranged like an epithelium, the biliary ducts 

 present the form of a plexus with five or six-angled meshes, 

 each of which includes an hepatic cell; in short, the appearances 

 found are precisely similar to those which have been above de- 

 scribed as occurring in the liver of Mammals. 



As I have elsewhere shown in regard to the intralobular
