DESCRIPTION OF PLATE VII, 



Illustrating Prof. Cleland's paper on the Grey Matter of the 

 Cerebral Convolutions. 



Fig. 1, is a vertical view of the whole depth of the grey matter, not taken 

 from any one specimen, but exhibiting the structure as it may be 

 made out from a number of specimens, only very much shortened. 



„ 2, copied from a specimen stained and preserved in glycerine, shows 

 the appearance of some of the smallest nerve-corpuscles, where 

 the external layer of nucleated protoplasm passes into the subja- 

 cent layer. 



,, 3, taken from a position considerably deeper than that represented in 

 fig. 2, shows various appearances of nerve-corpuscles and nuclei as 

 they lay in the specimen. 



„ 4, shows a nerve- cor [juscle with three poles, each apparently continued 

 into a medullated fibre. 



,, 5, is a similarly shaped corpuscle to that shown in fig. 4, but with the 

 horizontal and deep processes branching. 



,, 6, is a large nerve-corpuscle liberated from the surrounding textures, 

 and with small portions of granuliferous matrix, adhering to two 

 of its basal processes. It shows globules within it, produced by 

 the running together of smaller granules in consequence of the 

 action of bile, and concealing the nucleus. It likewise exhibits an 

 appearance of striation like that described by Arndt, which is 

 interesting, as the corpuscle floated free without touching the 

 glass cover.
