Complete transcripts of letters are being made available through the Project’s website (www.darwinproject.ac.uk) after publication in the ongoing print edition of The Correspondence of Charles Darwin (Cambridge University Press 1985–). Metadata and summaries of all known letters (c. 15,000) appear in Ɛpsilon, and the full texts of available letters can also be searched, with links to the full texts.
Thanks CGE for two papers and for his assistance of many years ago.
Thanks CGE for memoir on the Bacillariae of Mexico [Abh. K. Akad. Wiss. Berlin (Phys.) (1869): 1–66].
Sends samples likely to contain Infusoria and some that Hooker collected in Antarctic regions.
Thanks for earth samples. Discusses Infusoria in samples from Galapagos and Cape Verde Islands. Would like samples from other sites. Will send further results of investigations.
Astonished that dust sample contains Infusoria. Thinks dust is volcanic. Will write account of falling dust [see 775]. Offers further samples.
Thanks for shipments of earth samples. Sends copy of article describing Infusoria in samples ["Einige vorläufige Resultate … über das Verhalten des kleinsten Lebens in den Oceanen", Ber. k. Preuss. Akad. Wiss. Berlin (1844): 182–207]. Asks for more information and samples, especially from the soundings of Ross’s expedition.
Has at last received first letter CGE wrote.
More specimens being sent.
Sends his sketch of paper ["Fine dust in the Atlantic Ocean" (1846), Collected papers 1: 199–203].
D’Orbigny considers Pampas clay deposit result of debacle. CD cannot doubt it is slow, estuary deposit. Would be grateful for information on this point.
Would like sketch returned [see 775].
Would be particularly thankful for result of CGE’s observations on earth of Pampas.
Asks that Ernst Dieffenbach return copperplate and woodcuts.
Regrets J. D. Hooker did not visit Berlin.
Describes legal difficulties of Ernst Dieffenbach.
Lists species of Infusoria found in dust samples. Discusses origin of Atlantic dust. Discusses Infusoria in cosmetic paint from Tierra del Fuego and Patagonian earth. Thanks CD for samples. Would like samples from sea-bed.
Cannot doubt that Atlantic dust comes from Africa. Could Gulf Stream have brought South American organisms to African coast?
Has come to same conclusion as CGE on volcanic origin of Patagonian stone. Formation extends 550 miles.
Could CGE examine Pampas mud to see if Infusoria are freshwater or salt-water? Results would be important.
Discusses table of Atlantic dust samples. Thinks dust came from South America.
Discusses Patagonian tuff samples.
Answers CD’s query about material from Pampas. Believes deposit made in brackish water.
Criticises account of Atlantic dust in F. J. F. Meyen [Reise um die Erde (1834–5)].
Sends small specimens for CGE to examine if he wishes.
Thanks CGE for his letter on Atlantic Dust: CD hopes to send a little paper to the Geological Society of London.
If CGE should examine Pampæan mud, CD would like to know the result.
CGE’s account of Pampas mud confirms CD’s view of its origin. Will send Patagonian specimens. Discusses dust-carrying winds in the Atlantic.
Was not referring to F. J. F. Meyen’s voyage.
Corrects error concerning samples.
Sends an essay ["Mikrogeologische Studien über das kleinste Leben der Meeres-Tiefgründe aller Zonen und dessen geologischen Einfluss", Abhandlungen der Preussischen Akademie der Wissenschaften zu Berlin (1873): 131-98.]
with expressions of admiration. CGE is confident their differences will not estrange them.
Remembers with gratitude the [Atlantic] dust that CD made available to him in 1844 [see 747].
Thanks CGE for gift of his latest work [Mikrogeologische Studien (1873)].
Sends specimens. Asks for information about specimens from Rio Gallegos.
What does CGE mean by the term "Fluthgebiete"?
French translation gives impression that Ehrenberg attributes Pampas deposit to debacle.
Describes Infusoria in Rio Gallegos samples.
"Fluthgebiete" means estuary deposit.
Discusses dust samples from Malta. Asks for further samples.
Sends copy [of "Fine dust in the Atlantic Ocean", Collected papers 1: 199–202]. Attempting to obtain further samples for CGE.
