I had an abscess (carbunculous) for about 12 days (not yet quite healed) on my left arm, like the one that I had under the left armpit while I was staying with Engels in Manchester. But that is not the reason why I have delayed until today my answer to your letter of 17 inst. Since I would be most unwilling to cut across your plans, and was also personally interested in enjoying your company, I tried several ways of arranging the affair to fit in with your intentions. But it is absolutely impossible. At the end of August I must be in Holland with my relatives, where I have many affairs to settle that are of great interest and importance to me. My suggestion, to postpone the rendezvous to another time, was emphatically turned down because the people I am to meet are all tied to their business and can only meet me in Brussels at that particular time. So I shall leave London about the end of August. You must let me know when you will be back in Hanover. I shall see how far I can regulate my further progress to fit in. With best greetings to your dear wife and Fr nzchen. In all haste, as Tussychen  and Engels have just arrived. You see from these lines that we arrived safely in England, yesterday. We had a few sea adventures, and others, about which Jennychen will write you. Meanwhile, our heartiest greetings to the whole house. Special greetings to Madame la Comtesse and K uzchen. Ditto greetings from Engels, Lafargue, Mrs Marx, etc. The little one is better again.
