[London,] 10 November 1866 

Dear Engels, 

My best thanks for coming to my aid so quickly and ditto for the 
port wine. I know your own circumstances exactly, and that makes 
it doubly painful for me thus to put pressure on you. You know, we 

 on Capital 

13* 

really must put an end to this business once and for all, but that 
will not be possible until I can go to the Continent and act there in 
person. 

Next week the first batch of the manuscript’ will go off to Meissner at 
last. This summer and autumn it was really not the theory which 
caused the delay, but my physical and civil condition. It is just 3 
years ago now that the first carbuncle was lanced. Since then I 
have had only short periods of respite from it, and as Gumpert 
will confirm, of all types of work, theory is the most unsuitable if 
one has this devil’s brew in one’s blood. 

As regards the present fellow, it will be cured in the space of 
asout 14 days. I now know exactly how it has to be treated and I 
have therefore started taking the arsenic again. 

In great haste. 

Your 
K. Marx
