Finds the negative information sent by EF of great interest [see 9094].
More on his own experiments and the perplexing results when using the sensitive litmus paper.
Sends notes on waxy secretion on leaves for F. M. Balfour; cannot procure any more Dionaea.
Sends table showing relative force of impact of weight dropped on a plane inclined at different angles.
On bodies of varying elasticity bouncing off inclined planes [see 9096].
Sends some litmus paper for CD.
Suggests experiments on artificial digestion.
Feeding habits of the tobacco worm; it eats only five plants, all very different, but of same botanical family.
Apologises for his ignorance in interpreting the results secured in his testing with blue litmus paper.
Hopes to get another species of Desmodium from Mr Rollisson.
Sends Dionaea plant for experiment involving temperature.
Lists plants in which he is interested, including Neptunia and Mimosa species.
Do any strictly tropical plants have glaucous leaves?
Asks for observations on irritable plants.
Gratified that a man of JD’s experience agrees with him.
Would enjoy seeing him at Down but it could only be for a half-hour’s talk at most, because of his health.
Sends an essay ["Mikrogeologische Studien über das kleinste Leben der Meeres-Tiefgründe aller Zonen und dessen geologischen Einfluss", Abhandlungen der Preussischen Akademie der Wissenschaften zu Berlin (1873): 131-98.]
with expressions of admiration. CGE is confident their differences will not estrange them.
Remembers with gratitude the [Atlantic] dust that CD made available to him in 1844 [see 747].
Describes work on Nepenthes – more difficult than Drosera.
Has written to Dublin for a Drosophyllum.
Composition of the residue left on evaporation of the fluid in Nepenthes.
CD gives his criticisms of GHD’s essay on religion and the moral sense. Urges him to delay publishing for some months and then to consider whether it is new and important enough to counterbalance the effects of its publication. J. S. Mill would never have influenced the age as he has done had he not refrained from expressing his religious convictions. Cites John Morley’s Life of Voltaire [1872]: direct attacks produce little effect; real good comes from slow and silent side attacks. "My advice is to pause, pause, pause."
Thanks for TE’s work on [Beroe?] with illustrations of its parts [Zoologische Studien auf Capri 1 (1873)].
Lists observations he would like FD to make on the dried species of Desmodium at Kew.
Wants FD to look at the little lateral leaflets of Desmodium. CD has "a wild hypothesis that the little leaflets may be tendrils reconverted into leaflets".
Neptunia is evidently a hopeless case.
Good news that fluid of Nepenthes is acid.
No discovery ever gave him more pleasure than proving a true act of digestion in Drosera.
Has become profoundly interested in Desmodium. Asks whether Frank [Darwin] can look over the whole dried collection of the genus.
Has JDH any seed of Lathyrus nissolia?
