Is working one hour a day now, on illegitimate seedlings of Lythrum and Primula.

Begins to doubt John Scott’s accuracy about primrose and cowslip.

Does JDH believe in Karsten’s denial of parthenogenesis of Coelebogyne?

Will explain about the so-called hybrids of Lythrum when they meet.

JDH should not be proposed for Copley Medal this year because Royal Society Council has so few naturalists on it.

No summary available.

Darwin compliments ARW's papers published in the Proceedings of the Zoological Society of London and in the Journal of the Royal Geographical Society on geographical distribution in the Malay Archipelago.

Darwin agrees with Hooker's comments about ARW in Hooker's letter of 6 Oct 1865. Hooker's letter he describes ARW as: "... not a man of large sympathies, nor very charitable I think, & is certainly awfully cold & dry at times; yet he is essentially large minded, & very able".

Darwin refers to ARW's "On the phenomena of variation and geographical distribution as illustrated by the Papilionidae of the Malayan region".

Health very bad. All scientific work stopped for 2½ months.

E. B. Tylor’s Early history of mankind [1865] impresses him.

Would like JDH’s opinion of last number of Spencer’s [Principles of] Biology [vol. 1 (1864)], especially on umbellifers. CD not satisfied with Spencer’s views on irregular flowers.

ED reports on CD’s health.
