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.

Reconsidering variability of insular species.
Becoming convinced of the probability that the southern flora is a fragmentary one – all that remains of a great southern continent.
His difficulties in answering CD’s letter of 3 Jan [1852] [see 1469]. There is no Lepas mitra in the Lorenz Spengler collection. He undertakes to compare the specimens of Balanus sent by CD with those of Spengler.
He thanks CD for his book [Fossil Cirripedia (1851)].
His work with Professor Forchhammer and Mr Worsaae.
Explains the effects of the falling prices of wheat and cattle on the rents from CD’s and his sister Susan Elizabeth Darwin’s farms.
Asks for more information about CD’s idea of a ‘more permanent arrangement’ with his tenant.
Explains the drawback of a lease or a corn rent.
Discusses taxonomic relations of Alcippe.
Acknowledges the receipt of some securities.
Royal Society votes its Royal Medal for 1853 to CD. JDH reports the debate and vote at the Royal Society Council.
Honoured for Coral reefs
and Cirripedia.
Responds to CD’s criticism of his use of word "Kingdom" in discussing geographical distribution of Crustacea.
List of most anomalous Leguminosae [from George Bentham].
The only mainland vegetation he saw on Falkland Island shores were trees. Remembers no strange birds there, but on journey home saw a woodcock more than 500 miles from the nearest land.
Is relieved his book [Himalayan journals] has been well received and glad he has successfully completed it.
JDH summarises letter from Humboldt.
JDH answers CD’s questions on glacial action in Himalayas.
Birth of JDH’s second child.
Asks CD’s view of "highness" and "lowness" in animals. Gives his own for plants; extent of deviation from type, e.g., floral parts deviating from leaf.
Reading B. C. Brodie’s Psychological inquiries [1854].
JDH on "highness" of Coniferae: they are genuine Dicotyledons, not a link to cryptogams; that is a geologists’ fallacy. Thus they are highest plants in Carboniferous.
Does not agree with CD’s "elastic" species theory. Long correspondence with Lyell on this.
JDH and F. W. Binney identify Calamites specimens as pith casts. They are cryptogams related to, but higher than, Lycopodiaceae and contradict progression.
Insects found in coal.
Lyell says Stonesfield slate marsupials are actually placentals.
JDH reading Alexander Braun on individuality ["Das Individuum der Pflanze in seinem Verhältniss zur Species", Abh. K. Akad. Wiss. Berlin (Phys. Kl.) (1853): 19–122].
Reports that he sees the oxlip, cowslip, and primrose as really distinct species; hybrids are formed between any two.
The land shells, both fossil and recent, of Madeira and Porto Santo have features peculiar to them, so RTL would have no difficulty in identifying them.
Sends list of aberrant forms of Curculionidae.
Discusses in detail the artificiality of Carl Johan Schönherr’s classification. Sound generalisations about geographical distribution depend on sound classifications. Warns against putting too much faith in current catalogues.
Fossil leaves from Disko Island.
JDH to begin working out the botanical geography of the polar sea.
Has not forgotten CD’s request on aberrant species.
Has taken a house on Richmond Hill.
