FIG. 15. 



Represents the right hemisphere of the brain, in which the convolutions are cut away 

 to the depth of about three-quarters of an inch to show the fibres radiating from the cen- 

 tre of the outer surface of the great inferior ganglion into the convolutions. 



The white spot in the centre of the figure represents the outer surface of the great in- 

 ferior ganglion over which the fibres are drawn with great accuracy from the original. 



c Internal structure of the convolutions, e Fibres of the convolutions agglutinated by 

 a very delicate neurilema.
