London, British Museum of Natural History, 1968. Vol. 3, No. 6 of the Bulletin of the British Museum's Historical Series, printing the notes and summary that Darwin recorded while observing the flight routes of male humble bees, with his children, between 1854 and 1861. The summary was discovered, translated into German, and published in 1886; later published in English in 1965 (according to the introduction to this piece, by R.B. Freeman). This seems to be the first published version of Darwin's notes. Signed by Richard Freeman on the front cover, with the notation: "Part of this is a Darwin 'first' so you may like to have it/ I have sent one to Down House." Down House is the former home of Charles Darwin and his family. Very mild discoloration to covers; near fine in stapled wrappers. [#033620] SOLD
