central nerve fibrillae radiating toward the cells of the cortical gray 

 substance.) 



4. The outer gray layer. (This is the thickest of the three layers. 

 The prominent elements to be observed are : the scattering spheri- 

 cal neuroglia and small nerve-cells, nerve-fibrils passing at right 

 angles to the surface and lost as the outer region is approached, the 

 prominent blood-vessels which pass in from the pial investment.) 



FIG. 126. VERTICAL SECTION, CORTEX OF CEREBELLUM. PORTION OP SECTION SHOWN IN FIG. 125, 

 MORE HIGHLY MAGNIFIED, x 250. 



A. Outer layer of gray matter. 



B. Layer of Purkinje's cells. 

 G. Inner gray layer. 



D. White nerve substance. 



5. The ganglionic layer. (Directly beneath the outer layer the 

 section becomes deeply stained, from the presence of numerous small 

 cells, among and partly concealed by which are the large ganglion 

 cells of Purkinje. These are flask-shaped, and are arranged in a 

 single plane, with their long axes vertically. A thread-like prolon-
