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.

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.
Acknowledges a list [of plants?].
Looks forward to new edition [of British plants growing wild in the parish of Hitcham, Suffolk, 2d ed. (1855)].
JSH should not trouble about Anacharis until he is less busy. Will send cirripedes.
Thanks JSH for Anacharis which is flourishing.
P. H. Gosse told him he had several sea animals and algae living in artificial sea-water for over 13 months.
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.
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.
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.
More on seed-salting. JDH’s admission that he expected seeds to die in a week gives CD "a nice little triumph".
Praise for JL’s interesting paper ["On the freshwater entomostraca of South America", Trans. Entomol. Soc. Lond. n.s. 3 (1854–6): 232–46].
The new pigeon house is nearly complete.
CD is busy trying all sorts of experiments on salting seeds.
Is collecting facts on variation; questions AG on the alpine flora of the U. S.
Sends a list of plants from AG’s Manual of botany [1848] and asks him to append the ranges of the species.
JDH to be appointed Assistant Director at Kew.
On where to publish seed-salting paper. Floating problem perhaps more important than germination.
CD upset because salted seeds do not float.
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.
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.
Asks whether JSH considers Lychnis diurna and L. vespertina species or varieties.
Asks for help with his work on hybrids.
Would like JSH to go over London catalogue of British plants, marking "close species", i.e., those he considers real species but which are very closely allied. Withholds his motive as it might influence the result.
Has found Agrostis with worms in every germen and no stamens on stigma.
Now has 46 kinds of peas all growing together.
Sends a list of plants with stamps to pay the Hitcham girls who will collect seeds for him.
Describes his work with seeds in salt water.
For his experiments he would like seeds collected from plants that grow both near Hitcham and in the Azores.
Explains again what JSH should do in marking "close species".
