London, 22 October 1884 

Dear Ede, 

I am laying aside my preface” to inform you: 

1. That I am sending you herewith, by registered mail, Marx’s 
‘Speech on the Question of Free Trade’. This irreplaceable copy, ac- 
quired with much difficulty at second-hand, must be returned to me 
after use. 

2. That I consider it necessary to print in the form of an appendix 
at the end of the Poverty the passage from A Contribution to the Critique of 
Political Economy concerning John Gray, the first precursor of Proudhon 
and Rodbertus, from p. 61, ‘the theory that labour time’, etc., up to the 
end of the section on p. 64.°°! Would you be so kind as to send it to 
Stuttgart forthwith? I refer to this appendix in the preface. Between us 
we shall have completely demolished the whole of this aspect of 
petty-bourgeois socialism and disposed at the same time of the reply 
to Rodbertus’ Utopia, for I shall use the preface to make good any 
other deficiencies. 

Whether or not you use the ‘libre échange’* as an appendix is for 
you to decide; I can’t think where else to put it, and can hardly ima- 
gine it would be effective simply as a pamphlet — as to which you are 
better judges than I. 

If Dietz should raise any difficulties regarding the Gray appendix, 
it might be included after the preface and the article on Proudhon

you yourselves will find.
