Dear Sir, 

In reply to your circular”? I regret to inform you that as the papers 
in my possession have not been sorted for the past 20 years, I cannot 
possibly search out F. A. Lange’s letters—there are only a few—from the 
pile until I have 3 or 4 weeks’ spare time in which to put the whole lot 
in order. As soon as I have finished the final editing of Volume III of 
Marx’s Capital—some time early next year—I must address myself to 
this task, for it admits of no further delay, whereupon I shall be glad to 
place the aforementioned letters at your disposal. 

You may, of course, publish my letters to Lange in full or in part 
depending on the circumstances, but in the latter case I would ask you to 
be good enough to ensure that the passages concerned appear in their full 
context. 

Yours faithfully, 
Fr. Engels
