Pi?. 19. Neuroffliar cells froir. tbe cerebellum. The cell- 

 bodies lie between the neurones of Purkinje. An astrocyte is 

 seen at (ast.); and a Bergmann's fibre at (bg.f.). The Golgi 

 method, " 230. 



Pi?.?0. Transverse section of the midbrain. The Kolters 

 method , "14. 



Pig. 21. Transverse section of the entire thickness of the 

 left optic lobe, showing the neurones of the tectum mesenceph- 

 ali. The Golgi method, * 46.

Pig. 18. Ependymal elemsnts from the cerebellum. Por the 

 sake of clearness, only a few of the fibres proper to the region 

 have been represented. The Golgi method, " 2 5 0.

 encepbali. The Golgi method, * 300. 



Pig. 23. Neurone from the deeper layer of the tectum mes- 

 encephali. The Golgi method, x 230. 



Pig. 24. Interbrain. Transverse section through the left 

 thalamus at the level of the chiasma. The dotted lines indi- 

 cate the extent of the thalamic nuclei. The Golgi method.
