Dear Sir

I am very much obliged to you for having kindly informed me of Jahn’s work, of which I had never heard.¹ From what you say, it would have been of the greatest use to me before writing the Descent of Man or correcting a second edition which is now just published.

Pray believe me | dear Sir | yours faithfully & obliged | Charles Darwin

See letter from F. T. Köppen, 13 November 1874 and n. 3. CD refers to Ferdinand Jahn and Jahn 1842.

Summary

Thanks FTK for telling him of Jahn’s work [see 9719], of which CD had not heard. It would have been of greatest use in writing Descent.
