Thanks WTT-D for Drosophyllum seeds.
Will not sign a petition, for he feels vivisection is essential to the progress of physiology.
Has failed with his experiments on aerial roots.
Starlings seem to share their food. Are they communists as they struggle for their existence?

Thanks GBNH for a fact about CD’s grandfather [Erasmus Darwin], but he will not be able to use it in his brief notice.
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.
Sends proofs of his preface [to EK’s Erasmus Darwin], with which he is disappointed. Suggests additions and improvements he would like to make.
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.
Asks that authoress be thanked for poem. Enjoyed poetry in old days; now cannot read a line.
Delighted that ERL will find time for original investigations.
Structure of some "very curious" tendrils.
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.
