Show 66 MR. F. 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, only touching upon certain regions. This being the state of our existing knowledge of the brain of the Gorilla, 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 m y possession at the present time. None of these brains have formed the basis of any previous description, so that m y contribution to the subject is so far absolutely new. Furthermore, the extent to which the Gorilla's brain has been adequately illustrated is very small: in Fig. 1. Brain of Gorilla belonging to Royal College of Surgeons. Dorsal view. As. Simian fissure. CM. Calloso-niarginal. S.f.s. Frontalis superior. SJ.m. Frontalis medius. F.p.i. Part of frontalis superior. P.O. Parieto-occipital. F.R. Fissure of Rolando. S.p.i. Praecentralis inferior, lp. Interparietal. P.c.s. Prascentralis 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 m y opinion, much more useful than elaborately shaded, but imperfectly lettered, lithographs. M y 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 |
