My dear Sir,

I am very much obliged to you for your kindness in having sent me the number of the “Bulletin of the Torrey Botanical club” containing two articles of especial interest for me and particularly for having sent me some days ago the number of “The Academy” containing a very honorable critique of my work.¹ As I do not know whether you are collecting and preserving the numbers of the latter journal, I return it to you.

As you are interested about my brothers researches, I must relate you that he is now about to investigate the most interesting but hitherto very hidden natural history of the Brazilian honey bees (Melipona and Trigona)   He has already the living peoples of different species of them in his house and has acquainted me with many new and interesting facts about them. I try now as completely as possible to obtain the literature about Melipona and Trigona, but till now with little success, the memoirs about this subject being dispersed in various journals and works. I hope, Mr. Frederick Smith, to whom I am obliged already for many assistances, will be good enough to give me the wanting information²

With many thanks | I remain, my dear Sir | yours very sincerely | H Müller.
