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 Continent, 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 Professor Owen. Even the venerable
Rudolph Wagner, whom no man will accuse of progressionist 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 assertions. 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 authorities,
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 opposition 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 hippocampus 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.
