Summary

Spoke to Henry Warburton, W. H. Fitton, and E. B. Greenough on CD’s idea of a Government grant for publication [not identified].

Will read at next meeting his paper on erect Nova Scotia fossil trees [Proc. Geol. Soc. Lond. 4 (1843–5): 176–8].

E. P. Halstead reports on shores rising off Burma and Bay of Bengal.

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.
