Decussation of Meynert's bundle 

 Meynert's bundle, cerebellar portion 



has no relation with the trigeminus nerve, but only with the lateral 

 line nerve. I therefore propose that it be known as the L. lineae 

 lateralis. 



I shall here make only a brief statement regarding the structure 

 of the acusticura, including the L, lineae lateralis. Three distinct 

 types of cells are present: first, and least numerous, cells with short 

 neurites, similar to those in the cerebellum ; second, minute cells 

 directly comparable with the granule cells of the granular layer of 

 the cerebellum ; and third, a large number of cells which are com- 

 parable with the Purkinje cells of the cerebellum. This last type of 

 cell deserves further notice. In that part of the acusticum which 

 borders on the cerebellar crest, are found numerous large cells whose 

 dendrites expand in the cerebellar crest, and present the peculiar
