Dear Sir
I must write a line to thank you for your extremely kind letter.1 The Editors of Kosmos have done me a quite unprecedented honour by the publication of the last number,—much of which, I can see, will interest me greatly.2
With cordial thanks | Yours faithfully | Charles Darwin
Krause was an editor of Kosmos; the February 1879 issue contained essays on CD’s life and work to mark his 70th birthday, and also featured an essay on Erasmus Darwin by Krause (Krause 1879a).
