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.
