194: PRACTICAL MICROSCOPY. 



VERTICAL SECTION OF HUMAN CEREBELLUM. PRE 

 PARED AS LAST SPECIMEN. (Figs. 125 and 126.) 



OBSERVE : 



1. The arrangement of the cortex in the form of leaflets. 



2. The extension of the gray laminae within even the minutest 

 folds of the leaves, so as to completely envelop the central white nerve-

 divide the outer gray matter into two prominent layers. The ex- 

 planation of this will follow increased amplification.)

 made out, and the general plan seen to consist, as in the cerebrum, of
