From Charles Lyell 2 November 1869
Summary
Comments on Huxley’s address ["Geological reform", Q. J. Geol. Soc. Lond. 25 (1869): xxxviii–liii].
Physicists have ignored variation in sea-level in calculating effects.
Doubts if sun only source of heat.
Notes average depth of sea is 15 times height of land.
Criticises CD’s concept of permanent continents.
Sedimentary strata of Alleghenies must have derived from continent located where Atlantic is. Thinks enormous amount of denudation, submergence, and elevation may have accompanied relatively insignificant organic changes.
