90 NORMAL HISTOLOGY. 



No. 8. An examination of the cerebellar cortex will exhibit three layers 

 the molecular layer, the layer of Purkinji's cells, and the granular 

 layer, located internally. The white matter will be found to be made 

 up of medullated fibres and neuroglia. Observe the primary and sec- 

 ondary convolutions. Notice the cells of Purkinji and their proto- 

 plasmic processes. Note also the pia mater. Drawings.
