{London,] 21 November 1860 

Dear Engels, 

Since Monday,’ my wife has been prostrated by an extremely 
virulent nervous fever. Yesterday, on Dr Allen’s orders, I found 
all 3 children lodgings away from home, for he was afraid of a 
possible infection. Allen says the illness is a dangerous one, but he 
hopes she'll pull through. Last Saturday my wife was already 
feeling most unwell and I noticed symptoms of fever, and 
therefore wanted to call the doctor. But she refused. Sunday ditto. 
On Monday, of course, I wouldn’t be put off any longer, and she 
herself felt that it wasn’t just any ordinary cold or some such. 

Szemere’s here. Will also be passing through Manchester and 
will call on you. 

Salut. 
Your 
K. M.
