seen. The cells also contain very fine granular or vesicular molecules. In 

 many cases, too, the cells of the human liver and of that of quadrupeds have 



larger and smaller semi-

their interior. The nu- 

 cleus is frequently quite in- 

 distinguishable ; aud not 

 unfrequently, on the other 

 hand, cells are observed 

 which are provided with 

 two separate nuclei. They 

 are massed in rows or 

 streaks between the vessels, 

 and, in sections made at 

 right angles to the iutra- 

 lobular veins, appear as if

radiating from the centre 

 of the lobules towards their 

 circumference. When ex- 

 amined with a higher mag- 

 nifying power, they are 

 observed to form a con- 

 tinuous web, or solid net- 

 work, the more obvious 



openings in which are the spaces occupied by the capillaries with which the 



cells are interlaced. 



Beale states that these cells often appear to be collections of viscid matter around 

 central nuclei, without any distinct cell-wall ; but this is open to question. According 

 to Schiff (quoted by Henle), the molecules contained within the hepatic cells consist 

 of the amyloid substance, which is formed in the liver, and from which the glucose 

 obtained from this organ is derived. 



The hepatic cells may be washed away from thin sections by dilute solu- 

 tions of caustic potash, and then the spaces which they occupied are emptied, 

 and the network of capillaries with which they were interlaced is brought 

 more clearly into view, as was pointed out by Rainey ; and likewise, accord- 

 ing to Henle, narrow bands, which he regards as formed of connective tissue, 

 are to be seen crossing the spaces.
