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.

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.
