Professor Owen repeated his erroneous assertions at the meeting of the
British Association in 1861, and again, without any obvious necessity,
and without adducing a single new fact or new argument, or being able in
any way to meet the crushing evidence from original dissections of
numerous Apes' brains, which had in the meanwhile been brought forward
by Prof. Rolleston,* ([Footnote] *On the Affinities of the Brain of the
Orang. 'Nat. Hist. Review', April, 1861.) F.R.S., Mr. Marshall,*
([Footnote] *On the Brain of a young Chimpanzee. 'Ibid.', July, 1861.)
F.R.S., Mr. Flower,* ([Footnote] *On the Posterior lobes of the Cerebrum
of the Quadrumana. 'Philosophical Transactions', 1862.) Mr. Turner,*
([Footnote] *On the anatomical Relations of the Surfaces of the
Tentorium to the Cerebrum and Cerebellum in Man and the lower Mammals.
'Proceedings of the Royal Society of Edinburgh', March, 1862.) and
myself,* ([Footnote] *On the Brain of Ateles. 'Proceedings of Zoological
Society', 1861.) revived the subject at the Cambridge meeting of the
same body in 1862. Not content with the tolerably vigorous repudiation
which these unprecedented proceedings met with in Section D, Professor
Owen sanctioned the publication of a version of his own statements,
accompanied by a strange misrepresentation of mine (as may be seen by
comparison of the 'Times' report of the discussion), in the 'Medical
Times' for October 11th, 1862. I subjoin the conclusion of my reply in
the same journal for October 25th.

"If this were a question of opinion, or a question of interpretation of
parts or of terms,--were it even a question of observation in which the
testimony of my own senses alone was pitted against that of another
person, I should adopt a very different tone in discussing this matter.
I should, in all humility, admit the likelihood of having myself erred
in judgment, failed in knowledge, or been blinded by prejudice.
