FIG. 21.--Drawings of the cerebral hemispheres of a Man and of a
Chimpanzee of the same length, in order to show the relative
proportions of the parts: the former taken from a specimen, which Mr.
Flower, Conservator of the Museum of the Royal College of Surgeons, was
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',
posterior cornu; 'x', the hippocampus minor.
In fact, all the abundant and trustworthy evidence (consisting of the
results of careful investigations directed to the determination of
these very questions, by skilled anatomists) which we now possess,
leads to the conviction that, so far from the posterior lobe, the
posterior cornu, and the hippocampus minor, being structures peculiar to
and characteristic of man, as they have been over and over again
asserted to be, even after the publication of the clearest
demonstration of the reverse, it is precisely these structures which are
the most marked cerebral characters common to man with the apes.
