Figs. 4 to 11 Eight transverse sections through the cerebellar region of Nec- 

 turus, arranged in series from a level slightly caudad of the rostral end of the an- 

 terior diverticulum of the recessus lateralis rhombencephali (fig. 4) to the superfi- 

 cial origin of the V nerve (fig. 11), to illustrate the arrangement of the chief fiber 

 tracts of this region. X 25. 



Figures 4, 5, 6, 9, 10 and 11 are drawn from a series of sections prepared by vom 

 Rath's method, and figures 7 and 8 from a series fixed in Zenker's fluid with the 

 acetic acid replaced by 10 per cent formalin and stained by Mallory's method. 

 The specimen from which figures 7 and 8 were drawn is somewhat flattened dorso- 

 ventrally and in both of these specimens the ventricular sulci are less clearly pre- 

 served than in some other specimens; cf. figures 12 to 16.
