Summary

Lateral teeth in Arcadae.

Summary

Orders John Pye Smith’s book [Relations between the Holy Scriptures and some parts of geological science (1839)].

Summary

Gives CD page references [in The new statistical account of Scotland, vol. 14, pp 446, 507] for information regarding parallel roads.

Summary

Describes results of experiments on cobwebs, "neither spider or anything else had caused a line to disappear". Apologises for having to draw this conclusion as she had cheered him so in his work on species.

Summary

Hybrid geese.

Summary

Enclosed MS by Lieut. W. Christopher misrepresents CD’s views. Contains errors in zoology.

Summary

Encloses letter and paper to be forwarded to B. J. Sulivan.

Summary

Cancelled: part of 1014. Thanks RF for his kindness on Beagle.

Summary

Discusses printing of a plate [for South America (1846)].

Summary

Note on editorial details concerning names of fossil shells [for South America, appendix]. The Latin for "Darwin" is "Darvinius".

Summary

Thanks JWL for having acceded to CD’s wish to acquire a piece of land to provide a sheltered walk at Down.

Summary

Describes his reasoning in classifying CD’s Turritella ambulacrum specimens into two sorts. GBS holds that distinguishing characters, whether of species or varieties, should always be noticed. [See South America, appendix, pl. III, fig. 49.]

Summary

Disappointed with Webb and Berthelot.

Delighted to hear of more species from the Galapagos, surprised to hear W. Indian character of flora.

Summary

Sends identifications of CD’s Bahia Blanca fossil shells [see 830].

Summary

Goes on the assumption that each species has one origin, is immutable, and migrates.

Disagrees with Gaudichaud[-Beaupré] that volcanic island species are polymorphous.

Some mundane genera vary, others do not (Senecio vs Gnaphalium).

John Lindley’s doctrine of longevity of trees is amazing.

Edward Forbes’s health is better.

Summary

Will come to visit Kew if Claude Gay speaks English. Otherwise would prefer to wait until spring.

Summary

Gives his opinion on the tropical character of fossil shells listed by CD. The shells of Navidad [Chile] are not particularly tropical.

Summary

Will visit JDH in spring.

Will JDH ask Gay what birds, reptiles, or mammifers inhabit Juan Fernández [Island]?

Has JDH seen William Herbert’s paper ["Local habitation and wants of plants", J. Hortic. Soc. Lond. 1 (1846): 44–9]?

Summary

Thinks JDH’s explanation of polymorphism on volcanic islands is probably correct.

Proposes experimental test to see whether alpine form of a plant is inherited like a true variety.

Summary

Returns copy [of J. Hortic. Soc. Lond.]. Mentions article by William Herbert ["Local habitation and wants of plants", J. Hortic. Soc. Lond. 1 (1846): 44–9].
