9. Records of Paleolithic Man from a New Locality in the Isle of Wight. 
By Professor E. B. Poutton, D.Sc., B.S. 
A series was exhibited of palzolithic implements and flakes from the north- 
east coast of the Isle of Wight, a locality in which paleolithic implements had 
not previously been found. The implements had been traced from the gravel 
shore, where implements were found by the reader of the paper, to the gravel 
escarpment itself by Miss Moseley. The series exhibited every stage, from the 
simple flake to the finished implement, clearly indicating that the implements had 
been manufactured 7m setu.

1, The Persistence in the Human Brain of certain Features wsually 
supposed to be distinctive of Apes. By G. Evuior Smitu, MD. 
The study of a large series of simple human brains belonging to various lowly 
(chiefly African) peoples has revealed the fact that the human brain may 
retain many features that are commonly supposed to be distinctive of apes. 
Although this statement can be applied to almost every part of the brain, it is 
especially in the occipital region of the cerebral hemisphere that the supposed 
distinctively simian characters are most exactly reproduced. This is due to the 
fact that the cortical area especially concerned with the reception of visual 
impulses is as well developed in the anthropoid apes as in man. The form of 
this visual area in the human brain is often greatly distorted, in an almost purely 
mechanical way, by the enormous increase in the size of the cortical area in front 
of it; but however much its shape in man may differ from that of the apes, its 
structure is identical. 
It isa most curious and enigmatic fact that the simian resemblance is much 
more often retained in the left than in the right occipital region, The reason for 
this is that the visual centre retracts towards the mesial surface to a distinctly 
greater degree on the right than the left side of most human brains; it is pushed 
backward, as it were, by a very great and quite a symmetrical expansion of the 
right inferior parietal region. 
This asymmetry of the brain often exercises an obvious influence on the shape 
of the cranium. 
The study of the form of the visual centre and its sulci in series of brains 
affords information of great anthropological value. 
Although large ‘ Affenspalten ’ may occur in people of various races, they are 
rarely symmetrical in the two hemispheres, except in the Negro races. In this, 
as well as in many other features, the Negro brain is distinctly more pithecoid than 
the brains of any other people known to the writer. 
2. A Note on the Brain of a Fetal Gorilla. 
By W. L. H. Duckworrta, JZ.A. 
The external features of this specimen have been described by the author in 
the ‘Journal of Anatomy and Physiology ’ and in the ‘ Archiy fiir Anthropologie.’ 
Both memoirs are illustrated, and the latter contains a skiagraph of the specimen. 
The external features of the brain are now considered alone. When exposed, no 
sulet were observed on the lateral aspects of the cerebrum; shortly after the first 
exposure a cleft was formed in the left hemisphere, and was shown in a photograph 
accompanying this communication. 
But the interest of the case is really concentrated in the appearances presented 
by the mesial aspect of the left hemisphere, a view of which was shown on the 
screen,
