To Daniel Oliver 12 [October 1860]
Summary
Wants to amend request [see 2946] if DO wants to try carbonate of ammonia experiment. Put third drop on midrib of leaf [of Dionaea] or inside upper side.
Sorry DO already has Origin. Would he like Journal of Travels [Journal of researches]?

To Daniel Oliver 14 October [1860]
Summary
Has examined nearly all British orchids.
Hooker’s error on Listera.
Change in colour and consistency of Drosera hair glands after leaf inflection. Analogous structures in Dionaea. Requests Oliver confirm these observations on live plants, of which he has none.
In a muddle over the effects of salts on insectivorous plants.

To Daniel Oliver 17 October [1860]
Summary
Thanks for information and extracts.
M. A. Curtis, quoted in ["Dionaea"] Penny encyclopedia [(1837) 8: 508], gives the only full account of Dionaea.
Concurs in DO’s explanation of Dionaea footstalk cells, which CD took for stomata.
Is using carbonate of ammonia as a substitute for flies and colour change in glands as index of action on Drosera. Suspects other nitrogenous compounds do not act till decomposed into carbonate of ammonia. Beginning to write Drosera paper. Action of nitrogenous compounds.

Summary
The best way to see cell movement in Drosera hair, is to cut off those lately inflected over a fly, sketch shape of red matter under high power, and repeat after one or two minutes.

To Daniel Oliver 20 October [1860]
Summary
Will take Natural History Review, but cannot write for it.
Has mass of notes on irritability in orchids,
but he ought to work on Variation.
Drosera was an interlude while away from home. Expectations for effect of carbonate of ammonia on Dionaea. The important phenomenon in Drosera is the segregation of the red fluid within the leaf, not action of carbonate of ammonia on the red fluid.

To Daniel Oliver 24 [September 1860]
Summary
Admires DO’s correlation of spiny tree species and dry hot climate. CD suggests that spines, like strange aroma of desert plants, protect against browsing where there are few plants.

DO’s candidacy for Professorship of Botany [at University College, London].

Summary
One thirty-thousandth of a grain of human hair inflects a single Drosera hair. Astonished by his results so he is not publishing until next summer. [Not published until 1875, Insectivorous plants. See ch. 2 for observations on inflection.]
Wants to study effects of acids on live Dionaea. Oliver should do their anatomy. Corresponding with chemical physiologists about carbonate of ammonia on roots.

Praise for DO’s paper on Hamamelidaceae ["On Sycopis", Trans. Linn. Soc. Lond. 23 (1862): 83–9, read 15 Mar 1860]. Everything points to its being a "bankrupt" family.
