Thanks Mr Beaton for his answer [to 3147].

Asks further questions on points raised in Beaton’s previous papers: whether crossing white and blue varieties of Anemone apennina produced many pale shades; whether the Mathiola incana and M. glabra which crossed freely were artificially or naturally crossed.

CD is delighted by Beaton’s assertion that "not a flower in a thousand is fertilised by its own immediate pollen".

Recounts his experiments with Leschenaultia formosa to show insect fertilisation.

Has checked over JH's letter on rainbows and will have it signed Herschel. Encloses a scrap about rain. Mr. Wheelwright's note is curious. Will send a copy of the London Review.

Joseph Hooker writes to inform Miles Berkeley that John Steven Henslow had died the previous day at 4am.
