Fig. 22 Transverse section slightly caudad of the plane of figure S and includ- 

 ing dorsally the eminentia cerebellaris ventralis (em. cb. v.) and ventrally a typical 

 secondary trigeminal neurone (em. V.). The section is oblique with the right side 

 much farther caudad than the left and the ventral side somewhat farther caudad 

 than the dorsal. Golgi method. X 100. 



Fig. 23 Transverse section at the level of the V roots, illustrating three neu- 

 rones of the eminentia trigemini (e7n.V.). From the same specimen as figure 22, 

 one section farther caudad. Golgi method. X 100. 



Fig. 24 Transverse section at the level of the V roots, illustrating a typical 

 neurone of the eminentia trigemini (em. F.). Golgi method. X 100.
