Summary

Memorial concerning British Museum collection.

Relation of Cape of Good Hope and Australian flora a great trouble. CD’s high estimation of importance of glacial period for distribution.

Summary

Does JDH’s Wahlenbergia confirm CD’s law? Variations of one species assume the character of a distinct but allied species or genus.

Seed-salting: old ones float and germinate.

Owen’s "grand paper" [? J. Proc. Linn. Soc. Lond. (Zool.) 2 (1858): 1–37].

Summary

CD’s opinion of Lyell’s Antiquity of man and of Owen’s comment on it.

Disappointed Lyell has not spoken out on species and on man.

Pleasure of new hothouse and the plants JDH supplied for it.

Summary

Royal Society medals.

Correlation of variability and abnormal development is G. R. Waterhouse’s law. Relation of this law to polymorphism.

Colouring and marks of ancestral horse deduced from facts observed in pigeons.

Summary

Thanks for Antarctic flora [Flora Antarctica (1844–7)].

Agrees geographical distribution will be "the key which will unlock the mystery of species".

Could JDH look over a rough sketch on species?

Summary

CD’s predicament with continental extensions: they would remove argument for multiple creations, yet he opposes the doctrine. Lyell will not express an opinion on this.

Lyell fears mutability would lead to more specific names.

Encloses copy of letters to Lyell [1910 and 1917].

Summary

Mystified by the origin of coal-plants.

Milne’s Glen Roy theory is absurd but, oddly, it has staggered CD in favour of Agassiz’s ice-lake theory.

Summary

Questions on variation in nature: taxa varying in one region but not another. Variation between vs within species. Rarity of variation in important organs within a species. G. R. Waterhouse’s views on variation in highly developed organs, which CD relates to variation in rudimentary organs.

Asks for cases of obligate self-fertilising plants.

[CD annotation proposes using the Steudel Nomenclator botanicus (1821–4) to determine if variable species occur in genera with many species.]

Summary

Whether or not there should be movement of particles according to Tyndall’s theory of glacial action ["Observations on glaciers", Not. Proc. R. Inst. G. B. 2: 54–8, 441–3].

CD subscribes to H. C. Sorby’s view of gneiss [Edinburgh New Philos. J. 55 (1853): 137–50].

Seed-salting.

Pigeons.

Significant differences in skeletons of domesticated rabbits.

Summary

Emcloses copies of correspondence concerning his dispute with John Lubbock.

Summary

Wide-ranging species more "improved" than relics in small areas because they exist in large numbers and thus are subject to intense competition.

His abstract is 330 folio pages long so far.

Summary

The Lyell–Falconer squabble.

Discusses island vs continental floras and their degree of modification.

Critical of Wallace.

CD’s observations on phyllotaxy.
