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.
Discusses possible cleistogamic flowers in Oxalis.
Sends belated birthday greetings
and an archaeological pamphlet.
Asks for CD’s autograph.
Fertilisation of orchids. Believes some plants so constituted as to dispense with cross-fertilisation.
Thinks flowers of Hottonia project from the stem nearly horizontally, perhaps slightly upwards.
Sorry that he cannot help with Pulmonaria angustifolia.
Thanks for Chauncey Wright’s work [Philosophical discussions (1877)].
Gladstone visited recently, and they discussed the future role of the United States as a world power.
Oliver cannot, as CD has requested, hunt for trimorphic flowers in the Herbarium’s collection of Oxalis specimens. He would help Frank if he comes.
Thanks for account of his work. Cannot read Dutch, but son has translated it.
Thanks for album sent by PH’s countrymen.
Regrets he cannot help on Oxalis question. He did not note the names of species with cleistogamic flowers as he thought they were sufficiently known.
Sends an informal title-page [for Orchids, 2d ed.].
Appreciates the condolences for Frank [on death of his wife, Amy].
Pangenesis supports the existence of gemmules; does not accept Galton’s experiments as disproving their existence or importance.
The editor of the Agricultural Gazette asks CD to settle a point being debated in his journal. Can a desirable breed of cattle, which is so inbred as to have scrofula, be maintained by crossing with a breed of healthy constitution?
CD apologises for his burdensome request of Oliver.
Criticises JDH’s notice on Forsythia, which JDH said was dioecious. Forsythia sent to CD from Kew was heterostylous.
Has received the sheets of EG’s Spanish translation of Origin. Regrets that he cannot undertake to read them because of his health, over-work, and having forgotten much of the language. What he has read seems clearly expressed.
A curious error – too late to change: in Cross and self-fertilisation CD has "cleistogenous" for "cleistogamous" flowers throughout.
Evidence for inheritance of constitutional diseases like scrofula so good that it seems rash to breed tainted animal.
Experiments given in Cross and self-fertilisation show that evil of inbreeding follows from near relations possessing closely similar constitution.
Size and vigour increased by breeding plants and animals from ancestors that lived some generations under different conditions of life.
Thanks CD for new [2d] edition of Orchids.
Mentions some observations on dimorphic plants.
Reports on a third species of Pontederia [see Forms of flowers, p. 185].
Describes some unusual grasses.
Reports rumours from southern Brazil concerning the existence of a gigantic subterranean animal.
Thanks for EK’s book [Werden und Vergehen (1876)].
Regrets he cannot write for EK’s journal, but his son, Francis, may do so.
Suggests EK as editor urge on readers [of Kosmos] the investigation of the causes of variability; why, for instance, do wild Pampas cattle change colour when domesticated? Thinks experiments and observations on recently domesticated animals and cultivated plants would throw light on the subject.
Thanks for specimens [of insects].
Wonders whether difference between male and female plays part in fertilisation of fig.
Flowers of Oxalis sensitiva, sent long ago, are trimorphic and cleistogamic.
Had found out his error [use of "cleistogenous" for "cleistogamous" in Cross and self-fertilisation] some timeago.
Is now writing on cleistogamic flowers [for Forms of flowers (1877)], and, with it, will have worked up all his old materials on plants. JVC will then have a rest from his labours of translation.
Proposes to construct an aquarium on Jersey and wants to use CD’s name in support of the project.
