Summary:

Thanks for AG’s Japan memoir [Mem. Am. Acad. Arts & Sci. 6 (1857–9): 377–452]. Does not think AG’s arguments for a warm post-glacial period are sufficient, but will not be sorry to be proved wrong.

Believes natural selection explains many classes of facts which repeated creation does not.

Writes of some responses to the Origin.
