Dear Sir

I am much obliged for your note. I shall probably receive the translation in a day or two.¹ The English edition is delayed only by the index, but will appear at the close of this year or very soon afterwards. Hence you may publish the German edit. on the last day of Dec^r.²

If you will refer to my former note you will find that I spoke of having given my previous works for translation to your firm without payment, but I said nothing about any future work.³ Will you be so good as to strike out of the list previously sent the name of “Prof. Ernst Häckel of Jena” & insert in its place the name of “Prof. Gegenbauer of Jena”.⁴

I hope the translation of my book may be successful in Germany, and I remain | Dear Sir | yours faithfully | Charles Darwin

I intend sending an English copy to Prof. E. Häckel
