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.
Would like WED to send a specimen of the unusual plant organ of which he sent a drawing.
Notes on drops of nectar on sepals of cypripedium.
Glad to hear of JS’s orchid paper [Trans. Bot. Soc. Edinburgh 7 (1863): 543–50].
Suggests experiments on peloria.
Wants to count seed of the self-fertile red cowslip with equal stamens and styles.
Can send account of Hottonia.
Can only conjecture that the problem occurs because the plant is not living in its natural conditions. Refers to what he said on Acropera [in Orchids]. Many plants under culture have sexual functions altered.
Asks PHG to look at bee Ophrys at Torquay to see if pollinia are ever removed. "It is my greatest puzzle."
PHG’s hypothesis [regarding the self-fertilising mechanism of Stanhopea] may prove quite true, but CD suggests that PHG should observe another spike to make sure. CD will observe his Stanhopea if it flowers.
CD has spoken to Hooker of JS’s scientific merit, but has not suggested him for a colonial appointment.
Advice on style of writing.
Making extensive extract of JS’s orchid paper to communicate to Linnean Society [J. Linn. Soc. Lond. (Bot.) 8 (1865): 162–7].
Sends Asa Gray letter to JDH. Gray’s "Coolness about England and U. S. beats anything".
John Scott’s difficulties at Edinburgh Botanic Garden.
JS’s paper on Primula crossing experiments.
Sends MS note about closing of stigma in orchids being dependent on affinity of pollen and independent of protusion of pollen-tubes.
Hooker is impressed by JS’s MS on closing of stigma.
He will help find him a position. Hooker says if it is known that JS agrees with CD’s views, he will be unpopular in Edinburgh.
GB’s address [Proc. Linn. Soc. Lond. (1863): xi–xxix] pleased him as much as Lyell’s book [Antiquity of man] disappointed him on species question. GB has done a "real good turn to the right side".
Recalls the long walks in Cambridge with the "expectant senior wrangler". Cannot accept invitation (related to meetings of the BAAS) because of continuing bad health, his own and that of his children.
Herbert Spencer’s work disappointing – "all words & generalities".
Discussion of, and thanks for, CLB’s new work, Races of the Old World [1863]. Special interest in p. 388 on colour and constitution; CD mentions questions sent previous year to surgeons serving in tropical countries regarding diseases and colour of hair and skin.
CD describes first observation of gyratory motion of tendrils: explains its adaptive function is to find objects to hold on to.
Thanks AG for references about phyllotaxy
and information on marriage laws.
Has been looking for dimorphism in Phlox and Euonymus.
Has observed the irritability of tendrils of Echinocystis with great interest. Was also struck by the rotating movements of the leading shoots, which he proposes to investigate.
Has caught a frog and examined its possibly rudimentary toe. Asks THH if he will dissect it.
Has heard THH is abused in Edinburgh Review and in Anthropological Review [reviews of Man’s place in nature, Edinburgh Rev. 117 (1863): 541–69 and Anthrop. Rev. 1 (1863): 107–17].
Owen on heterogeny and the aye-aye.
Has been very ill.
CD thanks the sender of a Cypripedium. He finds its pollination contrivances interesting.
