London, 29 March 1883 

Dear Cuno, 

Your letter evoked roars of laughter over here. °'? Anyone who 
knew Moor as he was at home and within his intimate circle, is aware 
that he was never called Marx there, or even Karl, but only Moor, 
just as each of us had his own nickname; indeed, at the point where 
nicknames ceased so too did the closest intimacy. Moor had been his 
nickname since his university days and on the Neue Rhewnische Zeitung 
he was always called Moor. If I had addressed him in any other way 
he would have thought something was amiss that needed putting 
right. 

Your
