To J. D. Cooper   4 February 1882

Down, | Beckenham, Kent. | (Railway Station | Orpington. S.E.R.)

Febr 4th. 1882.

My dear Sir

Will you be so good as to make on wood copies of the cuts enclosed in blue lines in Plate to enclosed paper.— Figs 1 & 2 to stand along side one another in upper line & Fig 3 (viz a, b, c, d, e,) in lower lines— Then, a, b, c &c, could stand rather closer together.—1

They must be fac-similes, the dark & pale purple being represented by darker & lighter shading.— The lines must all be delicate, as all are greatly magnified.2 Be so kind as to put them in hand as soon as you possibly can, as I want them for a paper soon to be read before Linnean Soc.y. Fig I & 2 & 3 might be given in type; but a & b, in fig. 2, & a, b, c, d, & e in Fig 3 must be engraved.—

Dear Sir | Yours very faithfully | Charles Darwin

I wish the pamphlet to be returned.—3 I shall soon have another sketch to be engraved.4

The woodcuts were illustrations for CD’s paper ‘Action of carbonate of ammonia on chlorophyll’, which was read before the Linnean Society on 6 March 1882. The three figures appear in ibid., p. 263, and are as specified here by CD.
A manuscript copy of the illustrations (in ink) is in DAR 28.2: B1a; these are pasted into a draft of ‘Action of carbonate of ammonia on chlorophyll’.
The ‘pamphlet’ was an article by Francis Darwin, ‘The process of aggregation in the tentacles of Drosera rotundifolia’ (F. Darwin 1876a). The article included a colour plate (ibid., plate 23) showing the process of aggregation; the plate contains the figures specified by CD (see also n. 1, above).
CD probably refers to the illustrations for his paper ‘Action of carbonate of ammonia on roots’ (illustrations on p. 254). Pencil drawings for these are in DAR 28.2: A1a–b.
