The Darwin Correspondence Project is publishing letters written by and to the naturalist Charles Darwin (1809–1882). 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.
CD has signed James Croll’s certificate [of nomination to Royal Society] with real pleasure.
Interested in the fossil scorpions found by AG in the Lower Carboniferous strata of Scotland. Hopes further searches will yield more land animals and offers to subscribe funds to such a search if it falls outside the Geological Survey’s work.
CD expresses his gratification that a geologist of AG’s standing and influence subscribes to the idea of the mutability of species.
Asks to borrow AG’s paper on denudation of flat or nearly flat surfaces ["On modern denudation", Trans. Geol. Soc. of Glasgow 3: 153-90]. CD has recently been making some observations he thinks throw a little light on the subject.
His admiration for the papers of AG [see 8119].
Relates his recent discovery that earthworms have brought to surface no less than 161 tons of dry earth over an area of 10 acres, thus creating the conditions for significant denudation. Would welcome information about the persistence of ridges and furrows in old pasture lands ploughed centuries ago. Do they run down the slopes or transversely? Refers to [A. C.] Ramsay, [James] Croll, Elie de Beaumont, and [Henry] Johnson.
Is obliged for valuable letter [see 8123] and encloses queries about the manner of gradual obliteration of ridges or furrows in old pasture lands in various parts of England.
Gives details of his experiment to test his observations of the downward flow of worm-casts.
Refers to [Lyon] Playfair, [A. C.] Ramsay, and AG’s edition of [J. B.] Jukes, [A student’s manual of geology, 3d ed., 1872].
