Has sent phyllotaxy paper to G. G. Stokes with the letter from CD to show credentials.

Will not have time to read new Sachs edition CD offered.

Thanks for CD’s sponsorship of paper [Proc. R. Soc. Lond. 21 (1873): 176–9].

On a correction JVC thinks should be made in Variation on vertebrae of ducks.

Discusses JDB’s views on the spread of human-like creatures across the world, and the development of language.

Concerned about GHD’s health. Sends a prescription for a cough mixture.

Acknowledges correction in text of Variation . "You are a most conscientious editor & are as careful as I am apt to be careless."

The Naples Zoological Station and its library are growing fast. His life is a constant battle with the municipality, but has managed to make a little progress on vertebrate ancestry and morphology. His views get further away from what is generally accepted.

A new [German] edition of Expression is to be done. Has CD anything to add or alter?

JVC cites an article on cessation of breathing during mental concentration that supports Gratiolet as quoted in Expression, p. 179.

Thanks for Chapman 1873 (Chapman, John. 1873. Neuralgia and kindred diseases of the nervous system).

Has heard from Ashwin Conway Newman of Guy’s Hospital of a case of a child without any prepuce whose father was a renegade, uncircumcised Jew, but whose ancestors had all been Jews. Newman thinks this a good case of inheritance with reversion. JP’s letter [missing] now shows how rash such a conclusion would be.

Sends a paper on evolution by his friend J. D. MacDonald ["Distribution of Invertebrata", Proc. R. Soc. Lond. 21 (1872–3): 218–23] for CD’s perusal before dispatching it to the Royal Society.

Has no corrections for second German edition [of Expression]. Plans to bring out an improved edition in a year or two.

Thanks for reference JVC sent.

At Asa Gray’s request, responds to CD’s questions about WMC’s observations on Dionaea and particularly about the size of the insects captured and the excitability of the leaves after an insect is captured.

He does not accept Wallace’s definition of instinct because it excludes "inherited experience", i.e., "knowledge acquired by and transmitted through ancestors".

House-flies do not seem to have an instinctive fear of trap-door spiders.

Miss Forster gives him news of CD.

Thanks for J. D. MacDonald’s paper ["Distribution of invertebrata", Proc. R. Soc. Lond. 21 (1872–3): 218–23].

CD feels lines of genetic connection between animals offer a most difficult problem; Ernst Haeckel may have done mischief by facing the difficulty.

A letter of recommendation for W. B. Dawkins in his application for the Woodwardian professorship of geology in the university of Cambridge.

Is glad JEG has made out what the guemul is ["On the Guémul", Ann. & Mag. Nat. Hist. 4th ser. 10 (1872): 445–6; 11 (1873): 214–20, 308–10].

Cannot find a publisher for Italian translation of Expression. Gives up the project.

Would like a museum set up illustrating origins, varieties, and uses of domestic animals; seeks CD’s approval of the idea.

Forwards Matthew Arnold’s Literature and dogma [1873].

Hopes they can secure Hooker for President of Royal Society.

Thanks MA for his Literature and dogma [1873].
