London, 29 November 1877 
41 Maitland Park Road, N. W. 

Dear Mrs Hess, 

Both I and Engels have been absent from London for some 
considerable time and, after returning, I necessarily had first to 
read our late friend’s book, before being in a position to write to 
you. 

Engels and I thank you very much for sending the same. In so 
far as we have any influence, we shall endeavour to disseminate it. 
It contains some brilliant notions but unfortunately—no doubt 
because Hess could not put the finishing touches to it—there are 
quite a number of dubious points that lend themselves to attack by 
professional natural scientists. 

Wishing you the best of success, I remain 

Yours sincerely, 
Karl Marx
