To Miles Joseph Berkeley   29 February [1856]


Preparing paper on seed-soaking for Linnean Society ["Action of sea-water on seeds", Collected papers 1: 264–73]. Wants to use MJB’s results. Lost ardour when he found seeds would not float.

Has grown MJB’s purest pea seeds and got a few variants. Gärtner’s experiments suggest direct action of pollen, but CD thinks it is "mere variation".

Thanks MJB for information which he is including in his article for the Linnean Society.

Refers to the peas "which produce the black or intensely purple pods". [See 1834 and 1836.]

From M. J. Berkeley   7 March 1856


Reports on breeding experiments with various seeds: corn, aubergine, kidney beans, sugar-peas. Speculates that cause of changes in seed colour in sugar-peas may be mere variation rather than result of impregnation.
