13 August 1866. Dear Fred, Lehnchen got to the post too late on Saturday to send off the two lines in which I acknowledged receipt of the £10 with best thanks. You must excuse me if I write no letter today. I have the most pressing business on my hands. Today I wrote a long French letter to Lafargue, informing him that I must have positive renseignements from his family as to his financial circumstances before the matter can proceed or develop into an arrangement. A letter he communicated to me yesterday from a famous French doctor in Paris speaks in his favour. Title of the book: “P. Trémaux: Origine et Transformations de L’Homme et des autres Êtres. Première Partie. Paris. (Librairie de L. Hachette) 1865.” The second part has not yet appeared. No plates. The fellow’s geological maps are in his other works. Enclosed a scrawl from Liebknecht. I am also sending you his newspapers, which are not worth a shot of powder. Salut! Yours, KM I shall also get hold of the main work by the Paris doctor mentioned above and send it to you to pass on, as soon as I have read it myself.
