To J. D. Hooker 7 March [1855]
Summary
Latitude overrules everything in distribution. Alpine distributions are like insular. Tabulating proportions.
T. V. Wollaston’s Madeira insects: many flightless, thus not blown to sea. TVW’s insects do not confirm Forbes’s Atlantis.

To J. D. Hooker 7 April [1855]
Summary
CD has begun seed-salting experiments. Wants JDH to write which seeds he expects to be easily killed [in salt water].
CD’s idea that coal-plants lived in salt water like mangroves made JDH savage.

To J. D. Hooker 13 April [1855]
Summary
Pea self-fertilisation: has forty-five varieties growing side by side.
Describes seed-salting experiments: e.g., immersion in tank filled with snow. Reports some successful germinations.
Made list of naturalised plants from Asa Gray’s Manual [of Botany] to calculate the proportions of the great families.

To J. D. Hooker 19 April [1855]
Summary
Rejects JDH’s suggestion that seed-salting experiments be conducted on huge scale. Only wishes to demonstrate possibility of sea transport, not establishment of any particular insular flora. More seed results.

Summary
More on seed-salting. JDH’s admission that he expected seeds to die in a week gives CD "a nice little triumph".

Summary
CD’s seed paper in Gardeners’ Chronicle [Collected papers 1: 255–8];
CD attacks Forbes’s "Atlantis".
Considers solutions to floating problem. Decides to test Azores seeds.
Photographs and drawings of CD.
Plant movement experiments with Hedysarum gyrans.

Summary
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.

To J. D. Hooker 5 June [1855]
Summary
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.

Summary
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.

Summary
CD experiments: sowing seeds in fields; "breaking" seeds’ constitution with coloured light; plant hybridisation. Compiling works on hybridism.
Respect for W. B. Carpenter.

To J. D. Hooker 18 [July 1855]
Summary
Has read a paper, presumably by JDH, using the Madeiran flora to argue against Forbes’s doctrine.
JDH asked how far CD will go in attributing common descent; he intends to show "the facts & arguments for & against the common descent of species of same genus; & then show how far the same arguments tell for or against forms, more & more widely different".
