My Dear Sir/

I lose no time in assuring you that we shall be delighted to reserve space in the April rev: of the “Contemporary Review” for Prof: Whitney’s article (on the terms mentioned so kindly in his letter)—.¹ Perhaps you will be so kind as to suggest to him that we should be glad to put as much as 20 pages at his disposal & would prefer a substantive paper of some such extent to the brief essay he seems to contemplate—if it would be agreeable to himself to let us have his longer article.²

I need hardly say that should you yourself be at all persuadable to write a few introductory pages—or even paragraphs—we shall feel as much honoured by them as Prof: Whitney would be benefitted—³

I am my dear Sir | Yours sincerely & | respectfully | James Knowles

To/ Charles Darwin Esq—
