2. Groups of cells forming portions of the hepatic cell- 

 columns, as at C. 



3. Cells containing fat-globules, D. 



4. Glycogen can be demonstrated in the hepatic cells of the 

 rabbit some hours after a meal of carrots. Harden in alcohol; 

 cut without imbedding;, stain with iodine solution '(see page 29), 

 which colors glycogen reddish brown.

A. A. Cells from human liver. 



B. Cells from same, showing below a blood-capillary in T. S. 



C. A blood-capillary with part of a column of cells. 



D. Human liver cells in a condition of fatty infiltration.

1. The central vein, C. V. (Note the exceedingly delicate 

 wall, and search for a trunk of the intralobular plexus in its con- 

 nection with this vein.) 



2. The blood-capillaries in longitudinal section, B.C. (Ob- 

 serve their tortuousness, bifurcations, and anastomoses.) 



3. Blood - capillaries in transection, T. S. (Should the
