Summary

Pleased with news of BAAS meeting

and Scott’s possible position as Thomas Anderson’s curator.

Suggests Wallace is due for a Royal Medal.

Agrees with JDH’s criticism of Lyell’s address [see 4614].

Bentham’s Linnean Society address treats continuity of life in a vague non-natural sense.

Rereading his old MS [Natural selection] CD is impressed with work he had already done.

Writing Variation much harder than Climbing plants.

Encloses request to JDH to propose, or suggest on his behalf, that the Ray Society publish a translation of C. F. von Gärtner’s Versuche und Beobachtungen über die Bastarderzeugung im Pflanzenreich (1849).

Summary

Sends Nepenthes laevis.

Wallace for the Royal Medal is a good thought.

W. H. Harvey is at Kew and JDH has asked him about desert climbers.

Summary

Rejoices that CD is beginning "the book of books", Variation.

Suggests that changes in colour of pollen, stigma, and corolla, as Scott reports in his Primula paper, may be related to changes in the insects required for pollination.

Supports Gärtner translation by Ray Society.

Comments on recent addresses by Lyell [Rep. BAAS 34 (1864): lx–lxxv], Bentham [Proc. Linn. Soc. Lond. 8 (1864): ix–xxiii], and Murchison [Rep. BAAS 34 (1864): 130–6].

Summary

JDH explains why he cannot take Scott on at Kew.

John Tyndall cannot answer CD’s questions on glaciers. Edward Frankland’s ignorance. In JDH’s opinion, heaviness of winter snowfall is the greatest element in size of glaciers and this is a function of low mean temperature. Discusses descent of glaciers.

Summary

Emma prepares JDH for his visit to Wedgwood factory and Barlaston.
