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.
Thanks for copy of part one of EPW’s Spicilegia biologica (Wright 1870).
Not discouraged by F. Müller’s Passiflora.
Observations on insects visiting barberries.
Has finished the article [on the action of the eyelids in Ned. Arch. Geneeskd. & Natuurkd. 5 (1870), also see 7238]; summarises: the occlusion of the eyelids protects the vessels, and the eye itself, against the danger of pressure caused by excessive expiratory action. The weakness of the conclusion is that the extent of the danger caused by the pressure to the normal state of the eye is not precisely known.
Comments on QdeB’s volume [Charles Darwin et ses précurseurs Français (1870)]. Mentions error concerning his views on Parus and nuthatch.
Discusses Canis magellanicus.
Discusses reception of his views in France and Germany.
Fertilisation of barberries.
Passiflora.
Is continuing his experiments on the comparative growth of crossed and self-fertilised plants.
Thanks Society for honour of his election as Honorary Member.
A detailed description of the physiological and anatomical processes related to the prolonged involuntary contraction of the orbicular muscles and the secretion of tears (as in retching, violent coughing, or laughing). [See Expression, p. 160.].
Writes of CD’s recent visit to Cambridge and the joy it gave him.
Orders seeds, ripened in Algiers; imported seed would be of no use. [Forwarded to Algiers by JDH, see 7272.]
Is surprised to find CD disagrees about the argus [see 7229]. TWW finds others he has consulted, including Edward Blyth, agree with him.
Thanks CD for his help and encouragement in his series of experiments [to test Pangenesis].
Thanks FD for seeds of Canna.
Still thinks it would be worth FD’s while looking at the fertilisation of Lotus; does not think Frank Darwin has exaggerated the novelty of the contrivance.
Thanks AS for his kindness towards himself and his family. Looks back with great satisfaction to his last visit ("as it will probably prove") to Cambridge.
Returns H. C. Watson’s letter.
CD must study JDH’s manner of arrangement of varieties and subspecies, etc.
Thanks FCD for information.
Hopes that translation of his paper will appear in Dublin Journal.
Notes experience of his son [Leonard Darwin] on engorgement of eyes with blood. Discusses secretion of tears when eye muscles are involuntarily contracted.
The Negro’s idea of beauty is the same as white man’s.
Believes the Jollops select for blackness.
Native immunity from coast fever is not complete.
Has found stone instruments.
Asks to have observations made of a person retching violently, but ejecting nothing from stomach, in order to test relation between spasmodic contraction of orbicular muscles and tears. CD believes tears are caused by matter filling nostrils.
CD sends a "curious drawing" [missing] relating to imitation and protection.
Has sent F. Müller "a long screed" about the Passiflora.
Returns copy of Duchenne (found in cupboard) with notes [see 7221].
Sends photograph of woman patient with hair standing on end.
