To R. F. Cooke   7 August 1872

My dear Sir

I enclose a Receipt.—¹ Thinking over the cost of stereotype of text, I looked at your former note, & find that I made a very stupid mistake. I thought you had said that the stereotypes would cost ^£40, whereas the sum is ^£30, & cost of setting up type is ^£40.— On this scale I sh^d. have proposed ^£45, but now will you agree to ^£50, instead of ^£55 for stereotype of type & wood-blocks.— M^rs Appleton will then get only the advantage over setting up the type himself of the cost of the stereotype plates, less carriage.—² When you inform me of the price of Heliotypes pray answer me this question.—³ I will then at once write to M^rs. Appleton.

I will tell the Appletons that they cannot publish an hour before we do, but that we will supply the plates, so that they may publish very soon after us. My dear Sir | Yours sincerely | C. Darwin
