Fig. 16. — The same section shown in Fig. 15 with the names of the 

 cerebellar fissures. Bolk's names are printed in full; others are abbre- 

 viated. Between the lingula and the lobus centralis is the sulcus pre- 

 centralis (S.prcen.) of Symington. Above the lobulus centralis is the 

 sulcus postcentral^ (S.pcen.) of Symington, or fissura preculminata of 

 Elliot Smith. The sulcus primarius of Bolk is the fissura prima of Elliot 

 Smith and the sulcus preclivalis of Symington. Above the declive is the 

 sulcus postclivalis (S.pcl.) of _ Symington. Between the folium and the 

 tuber is the sulcus horizontalis magnus (S.h.m.) of Symington. Between 

 the tuber and the pyramis is the sulcus postpyramidalis (S.ppy.) of Syming- 

 ton. Below the pyramis is the fissura secunda of Bolk and Elliot Smith, 

 or sulcus prepyramidalis of Symington. Between the uvula and the 

 nodulus is the sulcus uvulo-nodularis of Bolk or sulcus postnodularis of 

 Symington. For a corresponding section of the cerebellum of the sheep, 

 see Fig. 10. 



The recent investigations bearing on functional localization 

 in the cerebellum (Figs. 13-16) are numerous. They are very 

 briefly summarized with a bibliography by Davidson Black 

 ('16). See also: Andre-Thomas and Durupt ('14); Babinski
