76): "And
lastly, Schroeder van der Kolk and Vrolik (op. cit. p. 271), though
they particularly note that 'the lateral ventricle is distinguished
from that of Man by the very defective proportions of the posterior
cornu, wherein only a stripe is visible as an indication of the
hippocampus minor;' yet the Figure 4, in their second Plate, shows that
this posterior cornu is a perfectly distinct and unmistakeable
structure, quite as large as it often is in Man. It is the more
remarkable that Professor Owen should have overlooked the explicit
statement and figure of these authors, as it is quite obvious, on
comparison of the figures, that his woodcut of the brain of a Chimpanzee
(l. c. p. 19) is a reduced copy of the second figure of Messrs.
Schroeder van der Kolk and Vrolik's first Plate.
"As M. Gratiolet (l. c. p. 18), however is careful to remark,
'unfortunately the brain which they have taken as a model was greatly
altered (profondement affaisse), whence the general form of the brain
is given in these plates in a manner which is altogether incorrect.'
Indeed, it is perfectly obvious, from a comparison of a section of the
skull of the Chimpanzee with these figures, that such is the case; and
it is greatly to be regretted that so inadequate a figure should have
been taken as a typical representation of the Chimpanzee's brain.
