Advice to GHD on whether to accept invitation to lecture at the Royal Institution.

Murray has sent the Quarterly Review issue. CD has told Murray that he is convinced Mivart is the author and what he thinks of him.

Sends information about Indian and Australian species of Aldrovanda, Roridula, and Byblis.

Sends his observation of honey-bees gleaning after orioles had made holes in calyx of Missouri currant, while humble-bees were getting honey through the tube in the usual way.

Observation on the limitations on the power of digestion in Dionaea.

Sends index [of Descent, 2d ed.] with instructions for proof-reading.

Asks GHD questions about heat transmission; he wants to use it as an analogy to illustrate transmission of motor impulses through leaves of Dionaea.

After a conflict with the Museum’s trustees, he has been brutally evicted from his home and office. Plans to leave Australia and asks CD’s help.

GHD explains conduction, radiation, and convection.

His paper on political economy for Royal Institution lecture has reached 60 pages. Plans to send it to Contemporary Review.

Writes about instructions to compositor and return of proofs [of Descent]. Requests return of 2d volume of Descent, to which he may want to refer.

Thanks GHD for clear lecture on heat.

Will keep paper on proportion of sexes, in case GHD wants it again.

Wants him to translate some pages of Swedish or Norwegian sent by A. W. Malm, "a good man".

Glad to see the statistical paper ["Theory of exchange value", Fortn. Rev. n.s. 17 (1875): 243–53].

Thanks CD for Descent, 2d ed.

Comments on German edition of CD’s collected works.

Sales of his Anthropogenie [1874] in various countries.

Anticlericalism and progress of Darwinism in Germany.

On German translation of Descent [3d German, 2d English ed.]. Lists some misprints in proofs.

Forwards a photograph he thought had been lost. Has noticed that the two sides of the face are often asymmetric in portrait busts and statues.

Discusses expression on two halves of the face. Mentions photograph [of picture by Rubens].

Thanks for CD’s favourable opinion of his book [Les fourmis de la Suisse (1874)]. Habits of ants; observations on their carrying empty eggs.
