Dear Sir,

I have some doubts whether Fritz Müller would like extracts from his letters being published after so long an interval,—that is if the letter relates to the origin of mimicry; for he published about a year ago an excellent paper on this subject. I believe it was in the Jenaische Zeitschrift, but the paper is out of its proper place in my library & I cannot find it.¹ If you thought it worth while to send me your copy I could then judge about the publication of extracts.

I fear it is not likely that I shall have anything to communicate to the Entomological Soc.² I quite agree with you that it is a great pity that our Entomologists should confine themselves to describing species

Dear Sir | Yours faithfully | Ch. Darwin
