138 CEREBRAL STRUCTURE OF MAN AND THE APES. 



by Mr. Marshall, and by Mr. Flower, all, as you are aware, anato- 

 mists 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 Continent, all these able and conscien- 

 tious observers have with one accord testified to the accuracy of my 

 statements, and to the utter baselessness of the assertions of Professor 

 Owen. Even the venerable Itudolph "Wagner, whom no man will 

 accuse of progressional proclivities, has raised his voice on the same 

 side ; while not a single anatomist^ great or small, has supported 

 Professor Owen. 



" Now, I do not mean to suggest that scientific differences should 

 be settled by universal suffrage, but I do conceive that solid proofs 

 must be met by something more than empty and unsupported asser- 

 tions. Yet during the two years through which this preposterous 

 controversy has dragged its weary length, Professor Owen has not 

 ventured to bring forward a single preparation in support of his 

 often-repeated assertions. 



" The case stands thus, therefore :-— Not only are the statements 

 made by me in consonance with the doctrines of the best older au- 

 thorities, and with those of all recent investigators, but I am quite 

 ready to demonstrate them on the first monkey that comes to hand ; 

 while Professor Owen's assertions are not only in diametrical oppo- 

 sition to both old and new authorities, but he has not produced, 

 and, I will add, cannot produce, a single preparation which justifies 

 them." 



I now leave this subject, for the present. — For the credit of my 

 calling I should be glad to be, hereafter, for ever silent upon it. 

 But, unfortunately, this is a matter upon which, after all that has 

 occurred, no mistake or confusion of terms is possible — and in 

 affirming that the posterior lobe, the posterior cornu, and the hippo- 

 campus minor exist in certain Apes, I am stating either that which 

 is true, or that which I must know to be false. The question has 

 thus become one of personal veracity. For myself, I will accept no 

 other issue than this, grave as it is, to the present controversy.
