Summary

Baffling problems with Melastoma. Appreciates ARW’s help with it and the "gorze case".

Has read report of ARW’s paper [to Newcastle BAAS meeting, "On the geographical distribution of animal life"] in the Reader [2 (1863): 352–3].

Summary

Encloses flowers of Melastoma from Singapore.

Acclimatisation of plants.

Striped horses in London.

Bees’ cells; has been promised information from the East.

Summary

Remarks on ARW’s review of Samuel Haughton’s paper on bees’ cells

and Origin.

Agassiz’s strength as geologist and weakness in natural history theory.

Work problems.

His butterfly collection.

Problems with book on Malay journey.

Recommends Herbert Spencer and his Social statics.

Spencer’s "masterly" nebular hypothesis.

Summary

Wallace noticed that melastomads in Malay archipelago were visited by small Hymenoptera.

Darwinism discussed at the last meeting of the Zoological Society. The Darwinians had the best of it.

HWB has committed the "folly" of marriage [to Sarah Ann Mason, 15 Jan 1863].

Printing of vol. 1 [of Naturalist on the river Amazons] is nearly finished.

Summary

His admiration for HF’s paper on American fossil elephant.

Notes "temporary irruption of S. American forms into N. America".

Rejoices that HF has "smashed" case of Mastodon on Timor.

Shares HF’s anger at Owen.

He is eager to hear about fossil bird [Archaeopteryx].

Comments on criticisms of species theory by [Johann Andreas?] Wagner.

Describes research on fertilisation of Melastomataceae.

Summary

Jaw with teeth found associated with Archaeopteryx fossil. Waterhouse pronounces it a fish’s jaw.

Summary

Discusses Louis Agassiz’s theory of the glaciation of Brazil.

Summary

Further detailed comments on Geographical distribution.

Base treatment [of George Darwin] by Mivart in Quarterly Review [137 (1874): 40–77].

Summary

Encloses memorandum on Origin [1866]

discussing mimicry in mammals and birds,

abnormal habits shown by birds,

behaviour of cuckoos,

and analogies existing between mammals of the same geographical region.

Speculates on possible lines of development linking groups of mammals.

[CD’s notes on the verso of the letter are for his reply.]

Summary

Still working on book and has completed 620 out of 700 pages.

Rewrote memoir [on mimicry in Amazon Lepidoptera] for Trans. Linn. Soc. Lond. [23 (1862): 495–566].

Edwin Brown, HWB’s earliest naturalist friend, will have a hard time classifying Carabi as he is unable to travel.

Summary

Answers CD’s query on the free digits of Archaeopteryx.

Summary

Thinks Royal Society’s failure to honour W. J. Hooker may be due to small number of botanists on Council.

Interest in H. J. Carter’s papers in Annals and Magazine of Natural History on lower organisms.

On Wallace; anthropology.

H. H. Travers’ paper on Chatham Islands [J. Proc. Linn. Soc. Lond. 9 (1865): 135–44].

W. C. Wells’s paper of 1813 ["Essay on dew", Two Essays (1818)] anticipates discovery of natural selection.

Summary

Encloses extract [missing] on a caterpillar.

Mentions William Buckler’s magnificent drawings of caterpillars [The larvae of the British butterflies and moths, Ray Soc. (1886–91)], but doubts Buckler will lend them for any Darwinian purpose. John Hellins has a portion of drawings and is more liberal.

Summary

Offers enclosure demonstrating that natural selection could produce sterility of hybrids.

More on Pangenesis and the inadequacy of H. Spencer’s approach.

Summary

Has seen that ARW has read a paper to the Linnean Society.

Thinks that Herbert Spencer’s Social Statics (Spencer 1851) would be too deep for him.

Summary

Cannot aid TWW with respect to bees from East Indies. Suggests he write to Edward Blyth.

Thanks him for getting query on variation in bees circulated in Germany.

Summary

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.

Summary

JDH sends a list of the principal confirmatory evidences of CD’s theory which he has prepared at W. R. Grove’s request for Nottingham speech ["Presidential address", Rep. BAAS 26 (1866): liii–lxxxi].
