To Karl von Scherzer   22 September 1876

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

Sep. 22. 1876

Dear Sir

I am much obliged for your kind letter, & for sending me that of Prof. Wagner, together with his Essays— I have written to thank him—1

I am at present much overworked & out of health; therefore I shall not read the essays for some time, & when I do I will write to him.2 Under these circumstances I will not ask you to take the trouble of coming to see me.

I beg leave to remain | dear Sir | yours faithfully | Charles Darwin


Neither Scherzer’s nor Moritz Wagner’s letters have been found. Wagner’s essay ‘Der Naturproceß der Artbildung’ (The natural process of species formation; Wagner 1875) appeared between May and July 1875 in Das Ausland. It was later reprinted in a posthumous collection of Wagner’s essays (Wagner 1889, pp. 282–342). CD’s heavily annotated copy of the article is in the Darwin Pamphlet Collection–CUL.


Wagner, Moritz. 1875. Der Naturproceß der Artbildung. Das Ausland, 31 May 1875, pp. 425–8; 7 June 1875, pp. 449–52; 14 June 1875, pp. 473–5; 21 June 1875, pp. 490–3; 28 June 1875, pp. 513–16; 19 July 1875, pp. 570–5; 26 July 1875, pp. 589–93.

Thanks for sending Moritz Wagner’s letter and his essays [on "Der Naturprocess der Artbildung" in Das Ausland (1875)]. Will read them and write to Wagner when his health is better.

Declines to receive Scherzer at Down.
