EXPLANATION OF FIGURES. 

 All the figures are drawn with a magnification of about 240. 



B. L. — Basal fiber-layer. 



F. L. — Fiber-layer (underneath the Purkinje cells). 



G. L. — Granule layer. 

 L. e. — Limitans externa. 

 L. i. — Limitans interna. 

 P. C. — Purkinje cells. 

 S. m, — Sulcus mediauus. 



PLATE 1. 



Fig, I. Large Purkinje cells from a portion of the cerebellar plate where 

 the granular layer is lacking. 



Fig. 2. Small Purkinje cells. 



Figs, j-8. Various forms of nerve cells from the molecular layer. 



PLATE II. 



Fig. p. Small granule cells. 



Fig. 10. Small granule cells ; their axis-cylinders ascending between the 

 fiber-bundles of the granular layer. 



Fig. II, Section through a portion of the cerebellar plate, where Pur- 

 kinje cells are lacking. Compactly arranged ascending axis-cylinders from small 

 granule cells in the molecular layer. In the granular layer a number of cells, of 

 which the under ones send their axis-cylinders sidewise ; besides these, numer-
