Those cells of the roof-nucleus lying in the posterior 

 region have a differsnt ternination for their axones from the 

 one just described. In tnis instance, the axones pass poste- 

 riorly, instead of anteriorly, and they take a course into the 

 cerebellaii. The significance of this fact has been consider- 

 ed in Section V, Subsection 5. 



The cell-nucleus is a large, evenly rounded body, almost 

 invariably eccentric in its position, sometimes, even, lying 

 in i»hat appears to be a special protrusion of the general cell- 

 mass. The chromatin is distributed in the forte of a reticulum 

 of rather fine mesh which holds coarser granules at intervals. 

 The nucleolus is evenly rounded and of conspicuous size. Many 

 of the cells have t.vo or even more nucleoli. 



The cytoplasm, stained .vith methylen-blue, exhibits a 

 minutely punctate appearance even unler the highest amplifica- 

 tion, due, chiefly, to the minute size and diffuse distribu- 

 tion of the tigroid substance. The tigroids are quite densely 

 packed in the peripheral regions of the cell. In the field of 

 the nucleus, the prevailing forn of granule is rounded; farther 

 a/?ay, the shape is a more elongated one, the long axis being 

 tangential to the margin of the cell. Pig. 56 sho<«s the details 

 of cell-organization, Nissl staining. 



When these cells are stained with iron haematoxylin, they 

 exhibit what appears to be the equivalent of the perinuclear 

 reticulum of Golgi (1900). We fini the internal part of the
