Review' for 1861, an article wherein the truth of the three following
propositions was fully demonstrated (l. c. p. 71):--

"1. That the third lobe is neither peculiar to, nor characteristic of,
man, seeing that it exists in all the higher quadrumana."

the higher quadrumana."

"3. That the 'hippocampus minor' is neither peculiar to, nor
characteristic of, man, as it is found in certain of the higher
quadrumana."

Furthermore, this paper contains the following paragraph (p. 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,
