{[London,] 8 May 1875 

My dear Friend, 

I have just received a letter from a Berlin businessman * (a very 
upright man and of no political importance at all, at any rate in 
the eyes of the world and the police), who asks me to explain to 
him some points in Capital.°? When replying to him, which I did at 
once, I took the opportunity of requesting, in my turn, that he give 
me a safe address for your letters from Russia.” My letter will go 
off today. 

Yours ever, 

Karl Marx
