Summary

Comments on JDH’s list – very good, but Orchids and Primula paper have too indirect a bearing to be worth mentioning. The Eozoon is a very important fact and to a much lesser degree the Archaeopteryx. Müller’s Für Darwin [1864] perhaps the most important contribution.

CD has forgotten to mention Bates on variation and JDH’s Arctic paper ["Distribution of Arctic plants", Trans. Linn. Soc. Lond. 23 (1862): 251–348] in new edition of Origin.

Now finds that Owen claims to be originator of natural selection.

Hooker’s lecture to BAAS ["Insular floras"] was capital,

but hears Wallace’s paper [Address to Anthropology Section, Rep. BAAS 36 (1866): 93–4] was best.

Pleased RS continues zealous work for natural history.

CD considers the report that N. American antelopes’ horns are intermediate between hollow and solid horns of ruminants to be one of the more curious facts he has lately heard of with respect to higher animals [C. A. Canfield, "On the habits of the prongbuck", Proc. Zool. Soc. Lond. (1866): 105–11].

Summary

Had Busks and Lyells to dinner.
