Asks for titles of papers on structure of Nepenthes for use by R. L. Tait. Mentions paper by RLT.

Sends Mind. Henry Sidgwick’s article ["The theory of evolution in its application to practice", Mind 1 (1876): 52–67] is so clear it makes CD feel "a muddle-headed man". But he disagrees with Sidgwick on the origin of morality within tribes.

Is sure mathematical discussion of elevation of continents will be valued by geologists.

Requests permission to call upon EF any morning from Saturday through Tuesday.

Will call tomorrow morning.

Gives permission for a Spanish translation of the Origin and wishes it success.

Congratulates GJR on lecture ["The physiology of the nervous system of Medusa", Not. Proc. R. Inst. G. B. 8 (1875–8): 166–77].

Sends Thiselton-Dyer’s suggestions for references to Nepenthes,

and gives his opinion on what will influence the Royal Society’s Council in considering RLT’s candidacy.

Thanks for references for R. L. Tait.

Suggests JSBS’s new machine for observing arterial action be used to test CD’s hypothesis that blushing is caused by thinking intensely about a part of the body and thus releasing the arteries.

CD has just had an interview with Edward Frankland, who "almost laughs" at FD’s idea of getting potash and soda out of the soil by treating it with sulphuric acid. Asks FD to send him a soil sample to give to Frankland. Sends enclosures giving address and labels for soil samples.

Expresses his pride in FD, whose article ["On the structure of the snail’s heart", J. Anat. Physiol. 10 (1876): 506–10] was highly praised by G. H. Lewes.

Lewes has also been quoting FD’s letter in Nature [13 (1876): 384–5] on pycrotoxine in relation to the vivisection controversy.

Was introduced to James Sully, author of the article in Mind on Wilhelm Wundt ["Physiological psychology in Germany", 1 (1876): 20–43]

and Sensation and intuition (1874) [see 10320], by "Mrs Lewes" (George Eliot).

Thanks CC for dedication [of his Grundlage des Crustaceen-Systems (1876)]. Congratulates CC on completion of work.

Comments on the reaction of geologists to GHD’s work on elevation of continents.

His samples of earth have been sent for analysis. EF has saved CD and his son from wasted experimenting.

Thanks AWvH for his work on Justus Liebig [The life-work of Liebig (1876)].

Asking to borrow three wood blocks.

CD sends the gist of an extremely negative report from the [Royal Society’s] physiological referee on the value of RLT’s modifications of Brücke’s process for isolating pepsin [see 10470].

Reports seeing flowers of wild cherry bitten off in same manner as primroses [see 9418 and 9444]. In this case it was done by a squirrel, though birds also bite the flowers of the cherry-tree.

Thanks AD for sending a memoir on foliation of rocks ["Expériences sur la schistosité des roches", C. R. Hebd. Acad. Sci. 82 (1876): 710–16, 798–804]. Regrets to say that it never reached him.
