[London,] 18 April 1863 
Dear Engels, 

Lassalle sent me the enclosed piece of nonsense marked in red 
(the newspaper is that of E. Meyen***) a week ago today; so, it 
arrived just one day after I had written you the letter in which I 
gave you a short excerpt from Izzy’s latest pamphlet.* He now 
clearly expects me to enter the lists on his behalf. Que faire?” 

Your 
K. M.
