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).

Discusses FD’s observations on the protrusion of protoplasmic masses by cells of the teasel. Suggests analogy with amoeba. "I would work at this subject if I were you, to the point of death."

Comments on FD’s discovery – "if it so proves". It will be important to see whether the protoplasm oozes through the cell-walls [of Dipsacus] or whether it can be withdrawn.

Looks to FD’s "grand discovery" as almost certain. Suggests observations.

Forwards chapter [of Orchids (1877)] for correction.

Sadness at the death of Amy.

Suggests German works worth translating.

Is glad FD is keeping busy; he has worked excellently on proof-sheets [of Orchids (1877)].

FD’s corrections for Orchids [1877] are all very good and useful.

Sends last chapter of Orchids [1877] for revision.

Has some articles that might interest FD.

Has invited Ferdinand Cohn and his wife to Down but hopes they will not come.

Sends [unidentified] volume for FD.

Thanks FD for corrections [to Orchids (1877)].

Thinks Johann von Fischer’s paper on monkeys’ rumps [Der Zoologische Garten 17 (1876): 116–27, 174–9] worth translating, and he intends to write a letter on it to Nature [Collected papers 2: 207–11].

Sends an article for FD.

Is glad he is able to work on his teasel paper [Proc. R. Soc. Lond. 26 (1878): 4–8]; suggests some observations FD could make.

Asks for reference to an article on a mandrill.

Has seen notice on Empetrum but cannot understand how leaves in bud could act as fly-catchers.

Asks FD to write on his behalf and say that he is unwilling to join a deputation [on vivisection] and that he believes in the need to protect physiology as well as lower animals.

Asks FD to mollify Daniel Oliver and assure him that CD asks "only for what I wd. give my life’s blood for".

Asks for details of dimorphism in Sethia from Thwaites, Enumeratio plantarum Zeylaniae [1864]. [See Forms of flowers, p. 122.]

Asks FD to forward some eczema mixture to Southampton for him

and to hunt out notes on earthworm activity at Beaulieu Abbey.

Forwards an unspecified work for FD to read.

Sends letter and seeds from [F. J. Cohn].

Is working too hard.

Julius von Sachs will "swear & curse" when he finds out he has missed sensitiveness of root apex. Has been putting his notes together and the case is conclusive. [Dated "Saturday 10th" by CD.]
