Erratic boulders of the Azores.

Summary

Gives some observations on orchids and on some plants which seem to be dichogamous.

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.

Summary

JM states he will publish [Variation] on same basis as Origin, i.e., paying CD two-thirds of the profits.

In response to Asa Gray’s suggestion, he could supply Ticknor & Fields with 250 copies [of Origin, 4th ed.] at half-price.
