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.

Responds to CD’s questions about mountain vegetation of the Cape of Good Hope. The distribution of some plants provides problems for both migration and special creation hypotheses.

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.

Indigenous domestic animals of the New World.

Relationship of Newfoundland and Esquimo dogs to the wolf. Dogs like the Esquimo occur in Tibet and Siberia. Indian pariah dogs and jackals occasionally interbreed.

Describes domestic cats of India; reports cases of their interbreeding with wild cats. Wild cats are tamed for hunting.

Races of silkworm in India are crossed [see 1690].

Domesticated plants, fish, and birds of India.

Comments on local races and species of crows; it is impossible to trace a line of demarcation between races and species.

Variation in the ability of hybrids to propagate.

Indian cattle breeds; differences between Bos indicus and Bos taurus.

Is not satisfied that aboriginally wild species of horse and ass exist.

Believes all fancy breeds of pigeon originated in the East. Wild ancestors of pigeons, ducks, geese, and fowls. Interbreeding of wild species of pheasant.

[CD’s notes are an abstract of this letter.]

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.

Discusses publication and distribution of the Journal of the Proceedings of the Linnaean Society. Also discusses the influence of the Society and the status of natural sciences at Cambridge.

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.

No summary available.

Has filled up CD’s paper [see 1674].

Distribution and relationships of alpine flora in U. S.

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.

Reports that he sees the oxlip, cowslip, and primrose as really distinct species; hybrids are formed between any two.

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.
