From M. J. Berkeley 7 March 1856
Summary
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.

Summary
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".
