Orders a copy of Dassen 1837, Onderzoek aangaande de bladbewegingen (research on leaf movements), published in Tijdschrift voor Natuurlijke Geschiedenis en Physiologie IV p. 106.

Invites FG to visit.

Thanks for JWS’s updatings to his Darwinian bibliography and regrets he is a poor German scholar.

Sends his paper ["Tidal action as a geological cause", Proc. Liverpool Geol. Soc. 2 (1874): 50–72].

Has not yet studied CD’s list of South American molluscs.

Spottiswoode is pressing for an answer to invitation to GHD to lecture at the Royal Institution. GHD is having MS of the paper he has written sent to CD, so that CD can advise whether he should accept the invitation.

CD may keep the photograph of "the holy Mary of Egypt". TLB may have been led away by his imagination in thinking that one side of the face expressed repentance and the other devout joy.

Comments on David Ferrier’s observations on electrical stimulation of the brain. Extent of response relates to intensity of stimulus.

Crichton-Browne’s observations on the asymmetry of convolutions on the two sides of the brains of maniacs.

Thanks JF for copy of Cosmic philosophy [1874].

Statement of stock on hand of CD’s works.

Expression, curiously, at a dead stand-still.

GHD has been using E. Norman [CD’s copyist], and he apologises if this has caused delays to CD’s work.

Accepts CD’s suggestion of new edition of Descent, and asks that Murray supply the stereotype plates and woodcuts for $50 [dollars or pounds!?], as soon as possible; supply of copies of Descent is exhausted.

Will publish CD’s proposed book [Insectivorous plants (1875)] on same terms as other works.

Thanks JM for granting his request. Will write to D. Appleton.

CD is sorry about heavy loss from Expression; still thinks the book will sell in the course of years.

Mainly family news.

Eager to read GHD’s political economy MS "though Heaven knows whether I shall understand it".

Has just had printed a new edition of Descent [1874] and is anxious that this improved version be circulated in America.

Thanks WJB for his reference [see 9691]. Is curious fact that the humble bees did not use the pollen, but the hive bees did.

Cites examples of the inheritance of maternal impressions.

Will send Alexis Giraud-Teulon’s book [Origines de la famille (1874)], which he has received but not read, if JFM cares to read it.

Wishes to know where, in his works, CD refers to some particular behaviour in dogs.

Mentions the sensitivity of cirripedes to passing shadows.

Responds to the correspondent's comments on natural selection.

Is obliged for addressee’s courteous note and is indifferent to how his name is used.

Thanks for the present of the book [Thomas Belt, The naturalist in Nicaragua (1874)].
