To John Murray 31 May 
Down Bromley Kent
My dear Sir
Enclosed is the Diagram which I wish engraved on Copper on folding out Plate to face latter part of volume.—1 It is an odd looking affair, but is indispensable to show the nature of the very complex affinities of past & present animals.— I have given full instructions to Engraver, but must see a Proof.—2
A perfect shower of proof-sheets have arrived, (thanks to you) to my great satisfaction;3 but I find that my M.S, which I thought was pretty clear is very obscure, & I am sorry to say, both for time & expence sake, that my corrections are rather heavy, & will take me much longer time than I anticipated: I have informed Mess rs Clowes of this, that they may not lock up too much type.4
I think you wished to know when 8 or 10 sheets were completed & I will inform you.—
I am much obliged for your curious extract about the Mice.
A week of Hydropathy at Moor Park has done me a world of good.—
Pray believe me | My dear Sir | Yours very sincerely | C. Darwin
P.S Please to specify for Engraver height of page, which I can see, is enough for Diagram without horizontal fold.
P.S | If you much object to Plate, as too long, if printed on paper blank on one side so as to unfold clean out, I will give up: perhaps it will make the folding too complicated, but on that head you can judge.—
It has to be referred to in three parts of my volume.—
CD’s diagram [for chapter on "Divergence of character", Origin] is indispensable.
Finds he will have to make many corrections, his text is so obscure.
A week of hydropathy at Moor Park has done him a world of good.
