Fig. 2. A view of the surface of the brain, 

 exposed by removing the skull-cap. 



On the right side the brain is covered 

 by its dura mater : that membrane is cut 

 through, and turned aside, so as to ex- 

 pose the left hemisphere.

 horizontally in about the middle. 



It shews the difference of the cortical 

 and medullary substances, and the union 

 of the two hemispheres by the corpus 

 callosum.
