4. The portal canals G G. (These are readily detected on account 

 of the deeply stained nuclei of the cells lining the hepatic ducts. )

5. Portal canals (too small for demonstration of the several 

 elements, but always distinguishable by the bile-duct cells). 



6. The larger portal canals C. Note: (a) The large thin-
