In his paper for Geological Society ["Glacial origin of certain lakes", Q. J. Geol. Soc. Lond. 18 (1862): 185–204] he will prove that all the lake-basins of the Alps were scooped out by glaciers.

Sends his paper [on glacial lakes, see 3450]. Falconer attacked it. Falconer thinks Himalayas confound the theory, but Hooker writes that it explains the absence of lakes there.

Sends 3d ed. of catalogue of rocks [A descriptive catalogue of the rock specimens in the Museum of Practical Geology (1862)].

T. F. Jamieson’s paper on the parallel roads of Glen Roy to be read 20 January. Asks whether CD will be a referee.

Glad CD likes his Presidential Address to Geological Society [1863].

Will continue the practice [of discussing the break in succession of strata].

Has devised a diagram showing number of genera and species in each geological formation and the number that pass from formation to formation.

Describes the glaciated terrain of S. Wales.

Sends 2d ed. of his Physical geology [1864]; hopes that he will burn the 1st because of its errors.

ACR is convinced he is right about denudation of the Weald.

R. I. Murchison has criticised ACR’s glacial lake theory in his Presidential Address to Royal Geographical Society [J. R. Geogr. Soc. 34 (1864): cix–cxcii].

ACR has finished his Geology of N. Wales.

Lyell says CD is revising what he says about the Weald in the Origin. Asks CD to look at his subaerial denudation views in his book [Physical geology and geography of Great Britain, 2d ed. (1864)].
