Summary

Gives information on recent editions of Lyell’s works.

Summary

Sends rock specimen for W. H. Miller. Asks JSH to see whether there is any geology in P. B. Webb and Sabin Berthelot, Histoire naturelle des Îles Canaries [1835–50]. Finds his work on geology growing so large that it will take more than one volume and asks whether this will make publication aid more difficult.

Has accepted Secretaryship of the Geological Society.

Will not come to Cambridge because "as long as I continue well I cannot bear to leave my work for half a day".

Summary

Asks CD’s support for his application for the Chair of Geology at Oxford.

Summary

Illness has prevented his reading Origin. He has, however, expressed his [negative] opinion on the subject of mutability of species in his Manual of geology [1862]. Since his persuasions are so strong, he can do no less.

Summary

CD’s observations on the geology of S. Africa, which he considers of no value, were published in Volcanic islands.

Summary

Hopes CD has received a copy of his [Manual of] Geology [1862]; justifies his assertion that geology provides no evidence to support the view that life has evolved through a method of development from species to species.

Summary

Thanks CL for copy of his "grand book" [Principles of geology, 10th ed., vol. 1 (1867)]. Congratulates him on additions.

Summary

Cites article by David Forbes dealing with the geology of the S. American Cordillera ["Geology of Bolivia and South Peru", Q. J. Geol. Soc. Lond. 17 (1861): 7–62].

Discusses the flexures of the Cordillera, the age of the mountains, and basaltic dikes in granite areas.

Summary

Thanks for 3rd edition of ACR’s Physical geology and geography of Great Britain (A. C. Ramsay 1872).

Summary

Forwards copies of CD’s geology books.

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

Thanks for ACR’s Physical geology [5th ed. (1878)]; delighted with its success, proving there is a large body of men in England capable of appreciating sound geological science.

Summary

Thanks Quatrefages for his work on species. Explains that he received the Wollaston Medal for his three geological works.

Summary

Asks for account of sales of Geology of "Beagle". Willing to consider offer for remaining stock in order to close account.

Summary

Sends publication details of Coral reefs, which he thinks is now only available in Geology of the ‘Beagle’: Geological observations on coral reefs, volcanic islands, and on South America.

Summary

Comments on CL’s Principles of geology, 11th ed.

Discusses natural selection in man.

Summary

Encloses analysis of salt from Patagonia. Cannot account for its inferiority.

Summary

Discussion of his possible assistance on editorial work for revised edition of Descent.

Summary

Chapter 12 [of Variation] finished;

too late to include information on six-fingered men. Plans for book on man [Descent].

Mentions coral reefs of Tahiti.

Discusses volcanic islands; volcanoes of the Cordillera.

Summary

Sends corrections and suggestions for an advertisement for Zoology and Geology of "Beagle".
