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.
Will not sign a petition, for he feels vivisection is essential to the progress of physiology.
Starlings seem to share their food. Are they communists as they struggle for their existence?
Describes movement of a caterpillar.
FD’s experiment shows that caustic does not interfere with the bending of radicles. Believes that the apex is a kind of brain for certain movements, being specialised to receive certain irritations.
Stresses importance of ensuring that cauterisation of radicles does not, through injury, prevent movement. Plans an experiment to test for "apheliotropism" in certain radicles.
Heliotropism nomenclature. Apheliotropic mustard roots grow more quickly in dark. Measures growth with microscope as S. H. Vines did in mould. Studying air roots.
FD’s and Stahl’s negative opinion of Sachs.
CD gives suggestions concerning FD’s experiments on the radicles of roots. Asks him to find out whether J. von Sachs tried beans. Should also try other gramineous plants.
Bernard looking forward to his father’s return.
Francis wants a copy of a book on "Shakespeare’s merry tales" to present to a friend in Würzburg.
Inquires concerning a possibility of searching old deeds about the Darwin family history.
F. P. Cobbe called on EAD to present a letter from the Secretary of the Anti-Vivisection Society; she hoped CD might support limiting repetitions of experiments.
CD has corrected the first proofs [of Erasmus Darwin] and so returns RD’s books. CD is disappointed with his work and fears RD will be also.
Pressure paralyses the streaming of protoplasm in the hairs of Tradescantia.
Has received printed sheets from CD. Hopes CD does not intend to delete anything. EK comments on value of his own sketch for Erasmus Darwin.
Hopes CD can excuse article he wrote in response to a review of Grant Allen’s book [The colour-sense (1879)].
Points to CD’s favourable notice of his anthropological work;
details current financial difficulties and work efforts. Asks to borrow £5.
Has written to Col. J. L. Chester [genealogist] to ask whether he would like to see the deeds [for Darwin genealogy, see Emma Darwin 2: 237].
Is gratified if he has helped [with Erasmus Darwin].
Thanks for another consignment of family records.
Does not believe that deeds will throw light on the first William Darwin and his ancestors, but they will have much of interest for CD’s researches [for Erasmus Darwin].
Thanks CD for comments on Freie Wissenschaft und freie Lehre [1878].
Describes work on Medusae.
Describes work on Challenger Radiolaria and publication plans.
CD thinks nothing had better be done about the deeds at present.
Henrietta thinks Erasmus Darwin almost too dull to publish.
Notes observations on sensitivity and movement of radicles.
Has finished chapter [of Movement in plants] on sleeping plants and is now looking over heliotropism notes.
Is perplexed by Erasmus Darwin; Erasmus [A. Darwin] likes it, but Henrietta thinks it much too long.
Will shorten or leave out many parts [of Erasmus Darwin] but cannot agree that it is not worth while to say something about the family.
