To Karl Marx   1 October 1873

Down, | Beckenham, Kent.

Oct 1. 73

Dear Sir

I thank you for the honour which you have done me by sending me your great work on Capital;1 & I heartily wish that I was more worthy to receive it, by understanding more of the deep & important subject of political economy. Though our studies have been so different, I believe that we both earnestly desire the extension of knowledge, & that this in the long run is sure to add to the happiness of mankind.

I remain Dear Sir | Yours faithfully | Charles Darwin

The first volume of the second edition of Marx’s Das Kapital (Marx 1873) is in the Darwin Library–Down (later volumes were published only after Marx’s death).
