THE CENTRAL NERVOUS SYSTEM. 



Aside from the fact that the layer of polymorphous cellt con- 

 tains a few large pyramidal cells, it consists principally of (i) mul- 

 tipolar cells with short neuraxes (Golgi's cells) and (2) of cells with

 the surface of the brain (Martinotti's cells). Both these types of cells 

 are, however, not found exclusively in the layer of polymorphous
