London, 21 September 1875

Esteemed Sir, 

Your letter of 27 June reached me in good time, but the book’ 
did not arrive until much later, after I had already left London to 
take the cure at Karlsbad." Hence the delay in replying. I didn’t 
get back until yesterday. 

While tendering my best thanks for your letter and the first part 
of Thinen, I shall be presumptuous enough to ask for the 
biography of Thiinen you also offered. me.” If you do not possess 
the second edition of Capital I shall send it to you with the 
greatest pleasure. 

I have always regarded Thiinen as something of an exception 
among German economists, since it is exceedingly rare for an 
objective, independent inquirer to be found in their midst. 

I would endorse your preface in its entirety if our attitudes in 
regard to ‘wages’ did not differ materially. Thiinen and you 
yourself regard wages as the immediate expression of a genuine 
economic relation; I regard them as a spurious form concealing a 
content materially different from the expression of that form. 

I am, Sir, 
Yours faithfully, 
Karl Marx
