(e) That the tuft is frequently divided. 



(f) That the tuft is usually in contact with the capsule at 

 some one point, where search may be made for

A. Ascending limb of Henle's loop. 



B. Collecting tubule longitudinal section. 



C. Collecting tubule. The upper part of the tube is not sectioned , but shows the attached bases 

 of the lining cells; and thus simulates pavement epithelium. A, B, and C are in a pyramid of
