Flattered by JBJ’s discussion of coral reefs [in Voyage of H.M.S. "Fly" 1 (1847): 347–8]. CD has always thought his Coral reefs "too bold and speculative", so he is gratified "when anyone who has had opportunities of observation does not give his verdict against it".
Believes in the "perfect indefiniteness & frequently the vast length of the interval" between consecutive geological formations. Thus has little respect for arguments against CD based on the absence of transitional forms in the geological record. States that species found through series of beds do vary: some Silurian species have many synonyms which are really varieties of greatly differing ages. CD’s theory accounts for the progressive inprovement, multiplication and increase in complexity that can be seen, but which may often be only relative.
JBJ explains his theory of atmospheric denudation of Irish river valleys, to be published [as "On the river valleys in the south of Ireland", Q. J. Geol. Soc. Lond. 18 (1862): 378–403], and suggests its application to the Weald. This slow process would make the Weald far older than CD’s 300 million years.
Thanks for Orchids.
Elaborates his denudation theory: marine denudation works horizontally, atmospheric works vertically.
Answers point in CD’s letter on Sydney Harbour, N. S. W.
Who is the "goose" who reviews CD’s books in the Athenæum [review of Orchids, 24 May 1862]?
The statement on p. 87 of Origin that birds break the eggs with their own beaks should be revised.
The Geological Society cannot recommend anyone to the Government of Newfoundland, but CD advises JBJ to get a recommendation from Sedgwick.
CD’s support in JBJ’s controversy with Hugh Falconer is welcome. R. I. Murchison supports Falconer, and Lyell does not support their side strongly enough. Falconer and Jukes remain friends in private.
Advises JBJ on preparing himself for geological work in Newfoundland.
