 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

dendrites of Purkinje's cells; in part they run between the bodies of 

 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
