short axone and basket cells, and the coarser dendrites of the Purkinje 

 cells distinguishable (Fig. 346). 



The granular layer with ordinary stains presents the appearance 

 of closely packed nuclei with clear spaces here and there {^'islands'' 

 or "glomeruli) and also a few larger cells (Fig. 346). Most of these 

 nuclei belong to the granule cells, which are caryochrome cells. The 

 granule cells are small and possess three to six dendrites which are

comparatively short and terminate in the glomeruli with a compact 

 arborization, each branch of which ends in a small varicosity. The 

 axones of the granule cells, which are non-medullated, ascend into the 

 molecular layer where each divides into two branches running longi- 

 tudinally along the laminae and terminating in varicosities (Figs. 349, 

 351). These are the parallel fibres of the molecular layer. They 

 thus run at right angles to and through the dendritic expansions of
