274 PRACTICAL HISTOLOGY [XXXIV 



cells will be seen to cross one another. In a good 

 specimen a small process may be seen to run from the 

 deep portion of the cells towards the nuclear layer. 



The outer layer of the cortex contains, besides the 

 fibres from the cells of Purkinje, some scattered small 

 angular cells with relatively large nuclei; from these 

 cells one or more small branching processes may be 

 seen to proceed, the fibres and cells being imbedded 

 in a close fibrillar network; in this layer numerous 

 capillaries will be seen. 



4. Section of cerebellum (chrome-alum mixture, 

 medulla stain). Note the fine medullated fibres in the 

 nuclear layer and just outside the cells of Purkinje. 



DEMONSTRATIONS. 



1. Section of cortex of cerebral hemisphere treated 

 by the Golgi method (Less. xxxi. 9). (Foetal or 

 young mammal.) Note: 



The pyramidal cells with a large apical dendron, 

 smaller lateral dendrons, and a single axon which runs 

 towards the white matter. ' Thorns ' will probably be 

 seen on the main dendritic branches. 



2. A similar section, to show neuroglia cells. 



3. Section of the sigmoid gyrus and one of the 

 occipital lobe (dog: potassium bichromate, picrocarmine), 

 for comparison of cell layers. 



4. Section of cerebellum treated by Golgi method. 

 (Foetal or young mammal.) (a) cut parallel with the 

 laminae, (6) cut transversely to the laminae.
