THE CEREBELLAR CORTEX.

late cells, and the small cortical cells. The cells of Purkinje pos- 

 sess a large flask-shaped body (about 60 p in diameter), from which 

 one or more well-developed dendrites pass toward the periphery. 

 The latter branch freely and the main arborization has in each case 

 the general shape of a pair of deer's antlers. These dendrites 

 extend nearly to the periphery of the cerebellar cortex. In a 

 section horizontal to the surface of the organ the dendrites of the 

 Purkinje's cells are seen to lie in a plane very nearly vertical to the 

 surface of the convolutions, so that a longitudinal section through 

 the latter would show a profile view of the cells. In other words, 

 they have an appearance much like that of a vine trained upon a 

 trellis. The neuraxes of the cells of Purkinje arise from their basal 



Dendrite.

(inner) ends and extend through the granular layer into the medul- 

 lary substance. During their course they give off a few collaterals, 

 which pass backward to the molecular layer and end in telodendria 

 near the bodies of the cells of Purkinje. The stellate cells lie in 

 various planes of the molecular layer. Their peculiar interest lies 

 in the character of their neuraxes. The latter are situated in the 

 same plane as the dendrites of the cells of Purkinje, run parallel to 

 the surface of the convolution, and possess two types of collaterals. 

 Those of the first are short and branched ; those of the second 

 branch at a level with the cells of Purkinje, and form, together 

 with their telodendria, basket-like nets around the bodies of these 

 cells. The small cortical cells of the molecular layer are found
