 The second type likewise appears throughout. the gray stratum. 



The medullated nerve fibers found in the gray layer are prolonga- 

 tions of those in the granular stratum. In part they proceed toward the 

 surface, where, after losing their myelin, they end in branches among the

 Purkinje's cells lengthwise of the convolutions. 



The neuroglia of the cerebellum consists of short-rayed stellate cells 

 found in all the layers; of long-rayed cells in the white substance; and of 

 epculiar cells with small bodies at the outer boundary of the granular layer
