Summary

Sorry CD considers Horace Darwin unfit for school.

Summary

Impressed by JS’s attempts to fertilise Gongora.

CD has large collection of notes on orchids, but does not know when he will publish on them again.

Asks for JS’s papers on sterility of individual orchids and on Drosera.

Summary

Sends copy of the table, which now embodies CD’s suggestions [see 4117].

Gives instances of persons born with two thumbs and comments on hereditary factor.

Summary

Thanks for CD’s Linum paper [Collected papers 2: 93–105].

Has not published much because he would be ignored as a gardener; hence he is looking for a foreign appointment.

Has prepared orchid sterility paper at CD’s suggestion [Trans. Bot. Soc. Edinburgh 7 (1863): 543–50].

Summary

Working on monstrous Primula. Is ovule anatropous as Asa Gray says, or amphitropous? Does he know natural path of pollen tubes in Primula. Can the tube enter the ovule by the chalaza?

Summary

The ovule of Primula is amphitropous or what J. Georg Agardh calls apotropo-amphitropous [see Theoria systematis plantarum (1858), tab. 24, fig. 5–6].

Summary

Huxley’s lectures [Man’s place in nature (1863)]; he would be a scientific H. T. Buckle, if he were more careful.

Asks CD what the evidence is for inheritance of acquired characteristics.

Summary

Thanks WHF for photographs [of niata ox skull]. Will tell Quatrefages de Bréau about the cast. May have the photographs copied for woodcuts to illustrate his book on variation under domestication.

Summary

Thanks GGS for calculation [to determine the chances of the same peculiarity recurring in a family, see Variation 2: 5]

Summary

Cites instance in which different varieties of same species of plant flourished side by side under same conditions.

Summary

Discusses crossed varieties of sheep and ducks.

Summary

Doubts Decaisne’s report of larkspur self-fertilisation.

Enthusiastically observes climbing plants. Needs to know how novel his observations are. Finds R. J. H. Dutrochet has made similar observations, so he has wasted some time. [See Climbing plants, p. 1 n.]

Summary

Has just returned from collecting in Central America and is planning to go to the Galapagos to gather specimens in all branches of natural history.

Summary

Lyell has received compliments for letting readers draw own inferences [on species question]. Now feels he earlier did Lamarck injustice. [CD’s] substitution of variety-making power for volition [as in Lamarck] in some respects only a change of names.

Thinks Huxley taking on too many responsibilities.

Summary

Preparation for his address with particular concern that JP approve the part relating to [Adam] Sedgwick. Urges JP to sit at dinner with him as a sign of approval of the award [of the Copley Medal].

Admits his own dismay regarding the efforts of the younger geologists and zoologists to obtain the Copley Medal for CD on the grounds of the Origin and his anxiety about the next year’s award.

Summary

Discusses partnership in bank and whether Atherley would like to retire.

Summary

Sends his paper ["Über Dichogamie nach C. C. Sprengel und Ch. Darwin", Bot. Ztg. (1863): 1–7, 9–16].

Summary

Believes GM’s human bones from Gibraltar must be of very doubtful age. Lyell agrees, but feels any skull found should be forwarded to George Busk or Hugh Falconer.

Suggests GM look carefully for shells in the drift.

Summary

Encourages JS to publish on sterility of orchids and to experiment on Passiflora.

Doubted Hooker’s poppy case.

Describes case of primrose with three pistils: when pulled apart allowed pollen to be placed directly on ovules. This supports JS’s explanation of H. Crüger’s case.

Summary

Asa Gray will try to get HWB’s paper reviewed.

Also mentions that he (CD) wrote a short review of it for Natural History Review [Collected papers 2: 87–92].

Asks whether bees or Lepidoptera visit flowers of Melastomataceae.
