Your letter affected me both unpleasantly and pleasantly (you see, I always move in dialectical contradictions).
Unpleasantly, because I know your circumstances and it would be rotten of me if I were to accept such presents at the expense of your family. I therefore regard these £15 as a loan, which I shall in time repay.
Pleasantly, not only as a mark of your great friendship (and in the bustle of the world friendship is the only personal thing that matters), but also because you have helped me out of a very difficult position in regard to the forthcoming marriage. Apart from medicines and doctors, I have spent so much money in the last four months on blue books, enquiries and Yankee reports, etc, on banks, that I really had nothing left for my daughter.
You may be sure that I have often discussed leaving London for Geneva, not only with myself and my family, but also with Engels. Here I have to spend from £400 to £500 annually; in Geneva I could live on £200. But considered all in all, it is for the time being impossible. I can finish my work only in London. And only here can I hope to draw at least a comparatively decent monetary profit from this work. But to do that I must stay here for a time. Apart from the fact that, if I were to leave here at this critical time, the whole labour movement, which I influence from behind the scenes, would fall into very bad hands and go the wrong way.
So, for the time being, all drawbacks notwithstanding, fate ties me to London. Quant à  Koppel, you do him wrong. Had I not been ill, he would have amused me and such a diversion never hurts the family.
Engels and I have not written for Liebknecht’s paper hitherto. (Engels has now sent him two articles on my book.) Eccarius  is the usual London correspondent.
Borkheim  wrote an article against Herzen  and company.
M’s  letter gave me great pleasure. But he has to some extent misunderstood my development of the subject. Otherwise he would have seen that I described large-scale industry not only as the mother of the antagonism, but also as the producer of the material and spiritual conditions for resolving that antagonism, although it is true the solution cannot proceed along pleasant lines.
With regard to Factory Acts – as the primary condition for giving the working class elbow-room for development and movement – I demand them from the state, as a compulsory law, not only against the manufacturers, but against the workers themselves (on page 542, note 52,  I refer to the resistance offered by working women to a limitation of the working day). If Herr M develops the same energy as Owen,  he can break that resistance. That the individual manufacturer (apart from the extent to which he tries to affect legislation) can do little in the matter, I also say on page 243:  ‘But looking at things as a whole, all this does not, indeed, depend on the good or ill will of the individual capitalist [etc].’ See also note 114 (p 260).  That, nevertheless, the individual can do something has been clearly demonstrated by such manufacturers as Fielden,  Owen, etc. Their main effectiveness must of course be of a public nature. As for the Dolfuses  in Alsace, they are humbugs, who have managed, by the conditions enumerated in their contracts, to establish a comfortable serf-relationship to their workers which is at the same time very profitable to them. They have been thoroughly exposed in the Paris press and for that very reason one of the Dolfuses, a short time ago, introduced and got carried in the corps législatif  one of the most infamous paragraphs of the press law – that ‘la vie privée doit etre murée’. 
With warmest greetings to your dear wife.
À propos: Have you seen that my personal enemy, Schweitzer,  has heaped eulogies on my head in six numbers of the Sozialdemokrat because of my book? Very painful for that old harlot Hatzfeld.
