Fio. 21. Drawings of the cerebral hemispheres of a Man and of a Chim- 

 panzee of the same length, in order to show the relative proportions 

 of the parts : the former taken from a specimen, which Mr. Flower,

 good enough to dissect for me ; the latter, from the photograph of 

 a similarly dissected Chimpanzee's brain, given in Mr. Marshall's 

 paper above referred to. a, posterior lobe ; b, lateral ventricle ; c t 

 posterior cornu ; x, the hippocampus minor.
