Cannot read Duke of Argyll.

CD’s view of Asa Gray as foreign member of Royal Society; compares him to Candolle.

Summary

Had Busks and Lyells to dinner.

Examines and criticises evidence for CD’s hypothesis that the glacial period was not one of universal cold. Physicists deny its possibility.

Summary

Since his previous letter, has unexpectedly arranged to go to London next Tuesday.

Hopes to call on recipient.

Summary

Recommendations of books of general interest [for the Royal Society library]. These include [Louis] Agassiz’s works, [William] McGillivray’s [History of] British birds, and David Low’s [On the domesticated animals of the British Islands].

Comments on current candidates for the Royal Society.

Summary

Wishes CD could publish Origin with footnotes.

Increases in bird populations: starlings are increasing, but AN cannot give reason; mistletoe-thrush increasing but not ousting song-thrush. Doubts trustworthiness of [George?] Edwards, CD’s authority in Origin on this matter [see Origin, 6th ed., p. 59].

AN opposed to bird protection legislation to prohibit egging. Argues egging does not decrease number of birds.

Summary

Discusses chapter [6] on cleavage and foliation in South America. Notes especially cleavage where two series cross and cleavage as basis of foliation in metamorphosed rock. Notes foliation in rocks that have been liquefied by heat. Mentions case described in his "Geology of the Falkland Islands" [Collected papers 1: 203–12]. Discusses relationship of cleavage to beds. Speculations on association between grauwacke and clay-slates.

Summary

Response to ARW’s "grand and memorable work" [Geographical distribution (1876)]. Most interesting part to CD is ARW’s "protest against sinking imaginary continents".

Summary

In reply to CD’s query [see 2072], JDD describes what little is known about the crustacea of the Antarctic and southern lands.

Knows of no species of the cold temperate south identical with those of the cold temperate north.

Summary

Does not give much for botanical results of Round Island, but the zoology is wonderful.

Lyell’s new book [The student’s elements of geology (1870)]. Urges Lyell to make it Elementary principles.

Grove is disgusted with CD for being disquieted by William Thomson: "Take another dose of Huxley’s penultimate address to Geol. Soc." [Q. J. Geol. Soc. Lond. 25 (1869): 28–53].

Summary

CD would have carried the public more if he had explained adaptations by multiple causes, some unknown and some well known, i.e., natural selection.

Discusses Hooker’s views of extinction on St Helena.

Work on antiquity of man suspended.

Stopped by 11th edition of Principles of geology [1872].

Summary

Thanks for sending paper on geological development (Dana 1856). Discusses infertility of species. Discusses first part of Asa Gray’s paper (A. Gray 1856–7). Thanks for note on the Cave Rat. Discusses a new species of fossil cirripede, in the genus Chthamalus. Explains his interest in pigeon breeding.

Summary

Rule that species vary most in larger genera seems universal.

Response to Gardeners’ Chronicle note on "Bees and kidney beans" [Collected papers 1: 275–7].

Summary

Discusses at length CL’s criticisms of natural selection.

Comments on possible former connection between the Galapagos and South America.

Discounts survival of mammals on atolls.

Discusses reptile origin of mammals.

Discounts development of a mammal on an island and the descent of mammals from a bird.

The antiquity of islands.

Comments on bats of New Zealand. Geographical distribution of seals. Discusses Amblyrhynchus.

Summary

JDH approves MS section on geographical distribution.

Never felt so shaky about species before.

His objections to some mechanisms of distribution that CD proposes.

Summary

Has heard CD is much interested in questions relating to varieties and species. Mentions a case of a seminal variety of Colletia spinosa, described by John Lindley, which appears identical with another wild species of Colletia from S. America. Hopes CD will one day "enlighten us very much" on "the laws of species". There are many different views on the limits of species; M. F. Dunal made 50 species of Solanum which George Bentham considers are all varieties of S. nigrum.

Summary

Whether or not there should be movement of particles according to Tyndall’s theory of glacial action ["Observations on glaciers", Not. Proc. R. Inst. G. B. 2: 54–8, 441–3].
