ME. r. E. BEDDARD ON THE 



[Feb. 7, 



renewed study by v. Bischoff in 1882. There were five brains, but 

 the paper dealing with them was by no means exhaustive, oaly 

 touching upon certain regions. 



This being the state of our existing knowledge oB the brain 

 of tlie Grorilla, I have thought tbat it would not be a work of 

 supererogation to bring before the Society some notes upon five 

 Grorillas' brains which I have in my possession at the present 

 time. ISTone of these brains have formed the basis of any 

 previous description, so that my contribution to the subject is so 

 far absolutely new. Furthermore, the extent to which the 

 Grorilla's brain has been adequately illustrated is very small : in

 Frontalis meclius. F.p.i. Part of frontalis superior. P.O. Parieto-oceipital. 

 F.R. Fissure of Rolando. S.p.i. Pr£eeentralis inferior. Ip. Interparietal. 

 P.c.s. Prascen trails superior. S.f.i. Frontalis inferior. 



consequence of this deficiency I have thought it advisable to have a 

 number of simple drawings prepared, which are, in my opinion, 

 much more useful than elaborately shaded, but imperfectly lettered, 

 lithographs. My object in this contribution is a very modest one 

 A little too much, perhaps, of elaborate description, comparison 

 and generalization is sometimes based upon inadequate material
