4. Hepatic cell columns, H. C. (Note the difficulty with 

 which these can be- traced for any great distance, on account, e 

 their irregular and twisted course throughout the lobule. Ob- 

 serve that the lobules are composed largely of tortuous blood- 

 capillaries, between which the hepatic cell -columns are placed. 

 Note the manner in which the cells are disposed around the 

 blood capillaries, as at T. S.) 



5. Bile-capillaries, D. (These are rather difficult of demon- 

 stration in the human liver. The section should be extremely

thin, and, in order to get the best results, a higher power 

 instrument than we ordinarily use will be required. The 

 best point at which to see them is at the junction of three 

 or four cells, where the bile -capillary has been divided trans- 

 versely.
