Summary

All overworked at Kew.

Burchell collections enormous.

Lyell has sent MS of Principles p. 111 on changes of temperature. JDH thinks Lyell blunders and is out of his depth.

Charmed with E. B. Tylor’s book on man [Early history of mankind (1865)],

disappointed in Lubbock’s [Prehistoric times (1865)].

Summary

Sends Catalogue [of the collection of fossils in the Museum of Practical Geology (1865)], most of which was written in pre-Darwinian epoch [i.e., 1857].

Hears magnum opus [Variation] completely developed, though not yet born.

Summary

Bad month of sickness. John Chapman’s ice bag on spine.

Does not quite agree with JDH about Lubbock’s plagiarism charges. Lyell’s memory must have failed him.

Summary

No one believes in Karsten.

Surprised by CD’s observations that illegitimate crosses within a species produce hybrid-like offspring.

JDH’s scepticism of Scott’s observations.

On proposing James Hector vs Julius von Haast for Royal Society; on learned society honours.

Summary

Has done nothing since 1 May. Slowly getting better under Bence Jones’s diet.

The Reader has been sold – would regret its failure as a newspaper for general science.

Pangenesis is recovering from shock it received from THH’s criticism.

Summary

Reports Lincoln’s murder.

The end of Civil War is in sight.

Must look at dimorphism in Plantago.

Summary

On FitzRoy’s suicide.

The Lyell–Ramsay disagreement [on formation of lakes?].

Summary

Sends copies of the Field containing all the pigeon articles [see 4785].

Luke Wells will undertake engravings for Variation.

Summary

On Lubbock’s plans.

Visited by Antoine Auguste Laugel.

Guessed right on Bentham’s "Planchon".

Much struck by Thomson’s article on nomenclature [see 4812]; importance of this subject.

Sorry best scientists read so little; few read any long papers.

Summary

Kew affairs.

H. J. Carter’s observations are wonderful but want verification.

Skeptical of H. H. Travers’ observations.

Summary

Comments on CD’s Lythrum paper [Collected papers 2: 106–31]

and on H. Crüger’s orchid paper [J. Linn. Soc. Lond. (Bot.) 8 (1865): 127–35].

May take position at Calcutta Botanic Garden.

Regrets he cannot be elected to Linnean Society.

Pleased Asa Gray has commented on JS’s paper.

Summary

He has finished MEW’s work on hybrid willows [Die Bastardbefruchtung im Planzenreich (1865)] and sends his thanks. The extreme frequency of hybrid willows is new to CD, and he finds the explanation of their numbers in certain locations ingenious.

Comments on the criticism of Gärtner’s view of reversion

and the differences between MEW and Naudin.

CD now has doubts regarding his own view that hybrids are sterile from not being perfectly accommodated to their conditions of life.

Summary

Discusses "Climbing plants" and his own abstract of it.

CD should publish results of self-fertilising dimorphic plants.

Summary

Will return page on pigeons.

Has concluded his crossing experiments and found no trace of hybrid sterility or loss of fertility.

The Field is publishing a series of papers on different pigeon varieties [24 (1864): 366, 395, 459; 25 (1865): 115, 139, 155, 228, 258].

Summary

Delighted at CD’s praise of his book [Prehistoric times (1865)].

Summary

Discusses a variety of subjects: Cynips, galls, potato bugs,

male Daphnia laying eggs.

His Primula experiment results differ from John Scott’s.

Summary

Returns a paper which he has looked over.

Cannot name the scrap of Strychnos with any certainty.

Summary

Grateful for CD’s approval of Chapters on language.

Is inclined to believe that the races of man were primordially distinct.

Summary

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?

Summary

Instructions for Luke Wells about woodcuts for Variation.
