JDH suggests Scott go to India; he will write letters of introduction.

Conversation with Herbert Spencer.

George Bentham would like to know how CD’s view of hybridism diverges from Charles Naudin’s.

Sends specimens of Menyanthes with observations and drawings [see Forms of flowers, p. 115].

Sends dandelion [enclosed] with peculiar form of achene; suggests this solitary "sport" must have arisen by sudden jump from normal type.

Clarifies his letter of 18 May [4500].

Taeas [?] allied to L. hyssopifolia. [Cover containing packets of seed specimens.] Mentioned in the letter to H. C. Watson, 28 May [1864], f.2 (fS 4512).

Corrects his former account of cowslips.

The delay in the publication of JS’s Primula paper.

Delights in JS’s experimentation on Verbascum which confirms [C. F.] Gärtner’s statements.

Should be pleased if JS would accept offer of help.

CCB thought CD wanted live specimens, but now will send some dried ones from his herbarium.

Encloses an extract from a letter received from [J. D.] Hooker which suggests a job opportunity in India. Advises careful reflection about the risks and the need for a character recommendation. Would like to support the costs of the voyage and initial living expenses.

CD’s pleasure at JDH’s willingness to help Scott find a position in India.

Naudin underrates contamination of his experiments by insects. Thus CD doubts Naudin’s results on rapidity and universality of reversion in hybrids.

Wallace’s paper on man [see 4494] reflects his genius, although CD does not fully agree with it.

Encloses drawings of Menyanthes and Pulmonaria anthers.

Sends plant and directions to his home so that CD’s gardener may call for another plant.

Response to ARW’s papers on Papilionidae ["On the phenomena of variation and geographical distribution", Trans. Linn. Soc. Lond. 25 (1866): 1–71; abstract in Reader 3 (1864): 491–3],

and man ["The origin of human races", J. Anthropol. Soc. Lond. 2 (1864): clviii–clxxxvi].

The former is "really admirable" and will be influential.

The idea of the man paper is striking and new. Minor points of difference. Conjectures regarding racial differences; the possible correlation between complexion and constitution. His Query to Army surgeons to determine this point. Offers ARW his notes on man, which CD doubts he will be able to use.

On sexual selection in "our aristocracy"; primogeniture is a scheme for destroying natural selection.

[Letter incorrectly dated March by CD.]

Is slowly writing Lythrum paper [Collected papers 2: 106–31].

Thanks for [Charles?] Wright’s observations on orchids

– could he note what attracts insects to Begonia and Melastoma? H. Crüger, who was going to observe Melastomataceae, has died.

Describes the climbing habits of Bignonia capreolata and Eccremocarpus scaber.

How does AG know the perfect flowers of Voandzeia are quite sterile?

He has a case of dimorphism in holly; asks AG to report on American hollies.

Thanks HCW for Lythrum specimens.

CD has at last finished his Lythrum paper. ["Three forms of Lythrum", Collected papers 2: 106–31.]

Discusses the negative testimonial provided him by James McNab.

Sends testimonial from J. H. Balfour.

Would be glad if offered the sort of colonial opportunity Hooker suggests.

Argues the antiquity of the human species because natural selection acts differently with respect to men. Changes in man are largely confined to head and brain. Warfare and sex are very uncertain as means of selection.

Gives CD complete credit for theory of natural selection.

Is beginning his narrative of his travels.

Lyell argues against tracing man as far back as Miocene times. R. I. Murchison’s argument that Africa is the oldest existing land implies that Africa is the place to look for early man.

Forwards two character references for John Scott, for position JDH is arranging in India.

Request for climbing plants.

Acknowledges receipt of £242 11s. 10d.

Thanks JH for his kind enquiries about CD’s illness.

Thanks WL for his MS on coral and suggests that it be sent to the Geological Society for printing or preserving in the archives.

Comments on his and WL’s bad health and recalls WL’s past kindness to him.
