the crushing evidence from original dissections of numerous Apes’ brains, which 
had in the meanwhile been brought forward by Prof. Rolleston,* F-.R.S., 
Mr. Marshall,t F.R.S., Mr. Flower,{ Mr. Turner§ and myself,|| 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. Isubjoin the conclusion of my reply in the 
same journal for October 25th. 
“Tf 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. 
“ But no one pretends now, that the controversy is one of terms or of opinions. 
Novel and devoid of authority as some of Professor Owen’s proposed definitions 
may have been, they might be accepted without changing the great features of 
the case. Hence, though special investigations into these matters have been 
undertaken during the last two years by Dr. Allen Thomson, by Dr. Rolleston, 
by Mr. Marshall, and by Mr. Flower, all, as you are aware, anatomists of repute 
in this country, and by Professors Schroeder Van der Kolk, and Vrolik (whom 
Professor Owen incautiously tried to press into his own service) on the Conti- 
nent, all these able and conscientious observers have with one accord testified to 
the accuracy of my statements, and to the utter baselessness of the assertions of
