From R. F. Cooke   21 August 1872

50, Albemarle St. | W.

Augt. 21. 1872

My dear Sir

I have desired the Heliotype people, to proceed with the printing off, of 2000 sets at once for ourselves.1

I have written to Appleton’s agent, to say the price of 1000 sets will be £75.0.02

I also answered Mr Koch & told him neither the Electros or Heliotypes would be despatched unless paid for in advance.3

I have also made arrangements for the Index & I suppose all the Sheets, you have returned for press, may be considered safe to begin upon.

Mr Murray4 returns from Scotland this week & I hope to get away, the end of next week.

Yours faithfully | Robt. Cooke

C. Darwin Esq

The photographic plates for Expression were being printed by the London Heliotype Company.
The agent of the US publisher, D. Appleton and Co., was Charles Layton; he had agreed to the price of £50 for stereotypes of the text and electrotypes of the woodcuts of Expression (see letter from Charles Layton, 13 August 1872).
CD had forwarded a note from the German publisher Eduard Friedrich Koch, regarding the German translation of Expression (letter to R. F. Cooke, 17 August 1872). Electros: electrotypes of the woodcut illustrations. The photographs were reproduced as heliotypes.
John Murray.
