Discusses rostellum and describes fertilisation of Epipactis.

Summary

Owen on the branchiae of Balanidae.

The Edinburgh Review article on the Origin [by Owen, 111 (1860): 487–532] full of misrepresentations, with a brutal attack on THH.

Summary

Mentions American edition of Origin.

A "savage" review [by John Duns] in North British Review [32 (1860): 455–68].

Comments on views of G. H. K. Thwaites on the survival of simple forms as a problem in his theory.

Marine origin of coal.

Illness of Etty.

Encloses article by Isidore Geoffroy Saint-Hilaire on hare–rabbit crosses [Histoire naturelle générale (1854–62) 3: 222].

Summary

Thanks for interesting letter which confirms belief that a good observer is a good theorist.

He is glad to hear that HWB, with his wide knowledge of natural history, has anticipated CD in many respects and agrees with the Origin.

Has been thoroughly attacked, especially by entomologists – J. O. Westwood, T. V. Wollaston, and Andrew Murray.

Glad HWB is writing on "equatorial refrigeration"; CD expresses his belief in north to south migration during glacial period.

Summary

Discusses P. T. A. Talandier as possible translator [of Origin].

Comments on reception of book in North America and opposition of Louis Agassiz.

Asks about reaction of Henri Milne-Edwards.

QdeB’s lectures on anthropology.

Summary

Summary

Discusses possible purchase of land.

Summary

CD’s list of fifteen converts. His opinions on opponents and supporters.

Summary

Thanks CL for loan of paper by J. S. Newberry ["Notes on the ancient vegetation of N. America", Am. J. Sci. 2d ser. 29 (1860): 208–18].

Mentions reviews of the Origin.

Discusses evolution of the domestic dog, especially with respect to the views of Owen, Pallas, and Isidore Geoffroy Saint-Hilaire.

Mentions W. B. Carpenter’s views on taxonomy.

Discusses hybridisation of plants and animals.

Comments on progress in human evolution.

Summary

WBC’s review [of Origin, Natl Rev. 10 (1860): 188–214] will do great good. It "turns the flanks of theological opposers" capitally.

Asks for information about cuckoo eggs and West Indian sheep.

Summary

Believes CD’s argument against special creation based on absence of terrestrial mammals on islands isolated before Pliocene era is very strong. However, the absence means Cetacea and bats have not modified towards terrestrial existence. There is similar lack of development of bats and rodents in Australia. Constancy among land shells of Madeira over long period shows that the majority of their species are immutable: a minority of "metamorphic" species maintains the overall number of true species while extinction removes many. Emphasis on the role of extinction discomfits CD’s opponents since the power of generation of new species ought to keep pace. Mentions Ammonite deposits with reference to CD’s comments on their apparent sudden extinction [Origin, pp. 321–2]. Perhaps absence of transmutation on slowly subsiding atolls indicates the slow rate of selective change.

Summary

Has received a batch of S. African specimens which contain many of the Atlantic genera he found in Madeira and the Canaries.

Summary

Comments on enclosed letters from Asa Gray and Wallace [missing].

Discusses hybrid fertility in rabbits and hares, and pheasants and fowls.

Asks about paper by Hermann Schaaffhausen ["Über Beständigkeit u. Umwandlung der Arten", Verh. Naturhist. Ver. Preuss. Rheinlande 10 (1853): 420–51].

Mentions criticism by Sedgwick and William Clark at Cambridge Philosophical Society.

Notes importance of CL and Hooker in defending Origin.

Comments on papers by D. A. Godron ["Considérations sur les migrations des végétaux", Acad. Stanislas Mem. Soc. Sci. Nancy (1853): 329–67].

Mentions receiving anonymous verses.

A Manchester newspaper lampoon shows CD has proved "might makes right" to be a universal law.

Summary

Very pleased with IGStH’s approval [of Origin]. Will be proud to place IGStH’s Résumé des lecons sur la question de l’espèce (I. Geoffroy Saint-Hilaire 1851) alongside his other works in his library.

Grateful for his offer to look over the difficult passages in Origin for a translator.

Summary

Discusses phases of climate.

Describes fossil mammals discovered by Auguste Bravard in South America.

Has had argument with Bishop of Oxford [Samuel Wilberforce] about CD’s book [Origin].

Discusses review in Annals and Magazine of Natural History. Guesses that T. V. Wollaston is the author.

Discusses evidence of shells on Madeira.

Comments on paper by Wallace ["On the zoological geography of the Malay Archipelago", J. Proc. Linn. Soc. Lond. (Zool.) 4 (1860): 172–84].

Summary

Satisfied that CD finds his conjectured rate of elevation and long periods of stasis reasonable, even if these periods cannot be estimated. Explaining upheaval by subterranean lava flow makes these pauses plausible. Suspects that mountainous areas move more than lowland and coastal areas. General upheavals or subsidence in Europe in glacial period are unlikely. Believes with Jamieson that there was glacial action in Scotland before its submergence and that it was equally mountainous then. Subterranean upheaval visits different countries by turn. Horizontal Silurian strata must have been submerged and upheaved. Rest has always been the general surface character. Believes, however, that the quantity of late Tertiary movement is against CD’s belief in the constancy of continents and oceans: perhaps since the Miocene period, but not since the Cretaceous.

Summary

Opinions on the Origin: AG thinks it masterly; Agassiz considers it very poor.

Summary

Admires Edward Forbes’s theory of continental extensions, but it will discourage investigation of distribution.

Mentions Oswald Heer’s proposed map of Atlantis.

Discusses extinction of plants caused by the glacial era. Migration of plants and animals during glacial period.

Encourages CL’s work [on Antiquity of man (1863)].

Comments on unfriendly reviews. Asks CL’s opinion about including a reply to reviewers in next edition of Origin.
