Asks about MJB’s experiments.
Thanks MJB for peas.
Thanks for approval of seed-soaking experiments in Gardeners’ Chronicle ["Does sea-water kill seeds?", 26 May 1855; Collected papers 1: 255–8]. They seem not to have convinced Hooker of consequences for geographical distribution.
Reports success of seed-soaking experiments. Celery and onion germinate after 85 days’ immersion.
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".
