From Joseph Beete Jukes 25 May 1862
Summary
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.

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]?
