The Charles Darwin Collection
The Darwin Correspondence Project is publishing letters written by and to the naturalist Charles Darwin (1809–1882). Complete transcripts of letters are being made available through the Project’s website (www.darwinproject.ac.uk) after publication in the ongoing print edition of The Correspondence of Charles Darwin (Cambridge University Press 1985–). Metadata and summaries of all known letters (c. 15,000) appear in Ɛpsilon, and the full texts of available letters can also be searched, with links to the full texts.
Has left a book from Henslow for JDH at Athenaeum.
When Asa Gray wrote, did he send marked sheets [of his Manual of botany]?
Has just made out "new & wonderful" specific character between two of his pigeon breeds.
When JDH goes to Germany, will he ask seed men if their marvellous true breeding lines are the result of selection.
Seeds of two tropical island plants have floated for ten days.
Sick of seed-salting.
Reading Candolle with great interest.
Naudin’s theory, in J. Decaisne’s review of Flora Indica, of subspecies descended from a single stock only adds to the confusion. John Lindley and M. J. Berkeley cut down species.
Very impressed by Candolle’s book [Géographie botanique raisonnée (1855)]. Wants to recalculate his results.
CD’s pigeon fancy is getting on.
Candolle discusses social plants. CD devises criterion for showing sociability not inherent.
Bentham’s buried seed plan rejected.
CD not sure that he can come to London.
CD’s tabulation of colonists curious but explicable.
Working on Tasmanian flora; contemplating general essay on Australian distribution: Tasmania and Australia same alpine species; Swan River flora very peculiar and quite distinct from New South Wales.
Trying to establish new journal at Linnean.
JDH criticises C. J. F. Bunbury’s paper on Madeira [J. Linn. Soc. Lond. (Bot.) 1 (1857): 1–35].
Absence of Ophrys on Madeira suggests to JDH a sequence in creation of groups.
Why are flightless insects common in desert?
Australian endemism.
Finds Forbes’s continental theories, migration, and double creation are all unsatisfactory explanations of geographical distribution of plants.
Is currently working on problems of sea transport of plant species.
European plants on Australian Alps only explicable by double creations.
Australian Leguminosae problem: of 900 species not ten are common to southwest and southeast. No migration; hence either creation or variation.
Himalayan thistles: graded intermediates between large and small English species, "shakes species to their foundations". Similarity of CD’s and his views on species.
