Summary:

Interested in ACR’s Presidential Address [Q. J. Geol. Soc. Lond. 19 (1863): xxix–lii] on the breaks in succession (of formations). Hopes ACR will provide a diagram of breaks, with the percentage of fossils that "pass upwards", i.e., continue to appear.

Horrified at Huxley’s geology.

Wishes ACR would discuss "creeps".
