Asks JDH not to send H. C. Watson’s paper on Azores plants [Hooker’s Lond. J. Bot. 2 (1843): 1–9, 125–31, 394–408; 3 (1844): 582–617; 6 (1847): 380–97].

CD cannot endure trying all the Azorean seeds.

Seeds: worried they will turn into another barnacle job.

Studies plants colonising abandoned field.

Experiment on plant sleep movements.

CD objects to "Atlantis" because no evidence; does not affect species theory.

Detailed response to JDH’s critique of sea transport and continental connection theories. JDH’s claim that low plants are widely distributed fits both theories.

Species theory does not touch origin of life.

Thanks for Hedysarum.

Pleasure in identifying field plants.

Has used borrowing rights at Linnean Society Library arranged for him by JDH.
