THE LIVER, BY EWALD BERING. 



essentially from those that have been hitherto given by others. All 

 the more recent observers, from E. H. Weber to Eberth, agree in 

 admitting the existence of hepatic trabeculce, which, composed either 

 of one or of several rows of cells, they believe to form a plexus that 

 interpenetrates the plexus formed by the capillaries. I have here 

 advanced my views on the subject, because the older ones appeared 

 to involve an impossibility, and because mine have already been cor- 

 roborated by Kolliker. If the hepatic cells were really arranged in 

 the form of trabeculae or tubes, each mesh of the capillary network

 trabeculse, or tubular processes formed by the hepatic cells, run dark 

 threads, which are the lines formed by the injection driven through the 

 hepatic duct. The empty spaces between the cells correspond to the 

 blood capillaries. 



must necessarily exhibit the transverse section of one of these trabeculae. 

 But the rows of cells which have led to the admission of trabeculaa lie 

 parallel to the capillaries, and to their long radially arranged meshes, 

 and are nothing more than parts of the whole cellular mass of the 

 liver everywhere traversed by capillaries, which have been isolated by 

 the direction in which the section has been carried. If we could con- 

 ceive numerous pallisades being planted at about the distance of their
