From J. D. Cooper   13 December 1878

188, Strand, W.C.

Dec 13. 1878

Dear Sir

Enclosed is proof and copy of the subject you left me reduced on to the block by Photography, and trust you will find it as you desire: with regard to the method of doing them by Photo it comes rather expensive but then you get a scientific accuracy, which is of the utmost value in a work like this still.1 I shall be prepared to undertake your work on as reasonable terms as possible for good work and the average cost may enable you to employ the means I suggest. Awaiting reply.

I am | Dear Sir | Yours truly | James D Cooper

Charles Darwin Esq

The proof has not been found. CD employed Cooper to engrave diagrams, reducing them when necessary, for Movement in plants (see ibid., p. 7 ). Cooper had previously made engravings for Descent and Expression (see Correspondence vols. 19 and 20).
