Morrill, Inneniation of Auditory Epitheliiini. 215 



cell. In other cases the fiber can be traced to the cell and may 

 end in a single enlargement at its very base. Occasional free 

 nerve endings were found in the central portions of the 

 auditory epithelium, at a considerable distance from the hair- 

 cells, and end free in enlargements. 



Conclusions. 



( I ) No continuation of the nerve into the cell was ob- 

 served although the cells were semi-transparent. 



( 2 ) No trace of Kaiser's cup-like mass was found at the 

 base of the hair-cells. 



( 3 ) The triangular enlargements at the points where the 

 nerves branch are due to the nerve sheath, through which the 

 nerve fibers can be seen. 



(4 ) Satisfactory evidence of anastomosis of nerve fibers 

 was not obtained. 



( 5 ) There are two kinds of nerve endings in the audi- 

 tory epithelium, the one being free near the surface and the 

 other ending in knob-like structures in contact with the base of 

 the hair-cells. 



(6) No varicosities were found on the nerve fibers in the 

 best stained preparations, while the terminal enlargement was 

 always present.
