MB. F. B. 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 exbaustive, only 

 toLiching upon certain regions. 



This being the state o£ our existing knowledge of the brain 

 oP the Grorilla, I have thought that it would not be a work of 

 supererogation to bring before the Society some notes upon five 

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

 time. None 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 medius. F.p.i. Part of frontalis superior. P.O. Parieto-occipital. 

 F.R. Fissure of Eolando. S.p.i. Prajcentralis inferior. Ip. Interparietal. 

 P.c.s. PrEBcentralis 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
