STRUCTURE OF THE CEREBELLUM.

like the Miillerian fibres of the retina. Lying between the two layers 

 of the grey matter is an incomplete stratum of large flask-shaped cells 

 (cells of Purkinje, c). Each of these gives off from its base a fine 

 process, which becomes the axis-cylinder of one of the medullated fibres 

 of the white centre, while from the opposite pole of the cell large 

 ramified processes spread out into the superficial layer of the grey 

 matter (dendrites}. 



H-4 e 



The dendrites of the cells of Purkinje spread out in planes transverse 

 to the direction of the lamellae of the organ, so that they present 

 a different appearance according to whether the section is taken across 

 the lamellae or along them (compare fig. 273, I. and II.). These 

 dendrites are invested at their attachment to the cell, and for some
