CD continues to have trouble reconciling the Veitch’s names for Bignonia plants and Kew names.

Lyell and Falconer called on CD in London.

R. I. Murchison’s address [see 4595] smashes Ramsay’s glacial theory.

JDH defends his view that CD should not answer Kölliker.

Pleased that Bentham is cautious about Naudin’s view of reversion. CD can show experimentally that crossing of races and species tends to bring back ancient characters.

Suggests Gärtner’s Bastarderzeugung [1849] be translated

and that Oliver review Scott’s Primula paper [J. Linn. Soc. Lond. (Bot.) 8 (1865): 78–126] for a future issue of Natural History Review.

Is working on Variation.

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].

Reports on personalities at the Bath meeting of BAAS [Sept 1864].

No summary available.

Darwin suggests that a Royal Medal might be bestowed on ARW before too long.

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).

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.
