Will look for botanical specimens CD requested.

Tells of a kestrel with a broken leg which apparently was forced to change its diet to worms and snails because of the injury.

On his father’s crossing experiments with cacti, in which hybrids were found quite fertile.

On his breeding of guinea-pigs.

Sends Miss E. Watts’s message about crested fowls and Brahmas.

Offers CD a live Proteus anguinus from Adelsberg cave. In his hands it will have a fair chance of developing into "some type of Columbidae (say a pouter or tumbler)".

The Origin is universally praised in Italy and Germany, even by those who disagree with it.

Notes observations on the spread of bees in New Zealand and their importance as pollinators of clover and other introduced plants.

Sends his article ["Quelques nouvelles espèces de poissons fossiles", Hollandsche Maatschappij der Wetenschappen, Haarlem 2d ser. 14 (1861)]

and Dutch translation of the Origin.

Elaborates on his article ["A popular exposition of Mr Darwin on the origin of species", Macmillan’s Mag. 3 (1860): 81–92]. Was anxious to point out that CD’s method of investigation is philosophically correct. Asks permission to call.

Distribution of varieties and subspecies.

George Maw’s review of the Origin [Zoologist 19 (1861): 7577–611].

Gives CD an instance of facts that can be read either way as to whether a plant (Veronica humifusa) is a species or a variety.

Evidence of glacial action in Australia. [See Origin, 4th ed., p. 443.]

CD awarded honorary doctorate of medicine and surgery by the University of Breslau. [See 3194a.]

Gives some observations on the sensitivity of Drosera species and comments on cases of "dioecio-dimorphism".

Thanks CD for his letter about GM’s review of the Origin.

Sends instances of correlative organisation and functions which he finds difficult to believe could have accumulated by gradual modifications.

[Letter erroneously dated 1862 by GM.]

The embryology of the vertebrate nervous system may be an exception to the law of inheritance at corresponding ages.

Observations from a fortnight in Lochaber. Found the entrance to Loch Treig to present the clearest evidence of intense glacial action. States, in contradiction of David Milne-Home, that there is glacial scoring in Glen Spean, as Louis Agassiz described, and moraine around the mouth of Loch Treig. There is little sign of water erosion on the rocks crossed by the lines in Glen Roy. Believes the smoothed rocks at the eastern end of Loch Laggan are due to flow from the lake and not tidal action. The lines in Glen Roy are too neat for a lake shore subject to tides. Given the glacial scoring sweeping round from Glen Spean into Glen Treig, and all the boulders, TFJ is astonished that anyone could deny that there had been glaciers there. [See 3247.]

The Primula experiments of J. Sidebotham; HCW’s distrust of the results [see J. Sidebotham, "Specific identity of the cowslip and the primrose", Phytologist 3 (1849): 703–5].

Offers to publish Orchids, giving CD one-half of the profits of each edition.

Mention of Volucella.

Has found the reference to Charles Morren’s paper, "On the agency of insects in causing sterility in flowers" [Proc. R. Entomol. Soc. Lond. 1 (1836): xliv–xlv].

Common white butterflies remove pollen-masses with their tarsi from plants of the Asclepiadaceae.

List of Australian plants that have become naturalised in the Nilgiris [India] and are turning out the native trees.

Discusses the mimicry of the Volucella flies, and the bees and wasps they mimic. Compares it with the different object of mimicry in butterflies.

Refers to incompleteness of Cuthbert Collingwood’s paper [? "On homophormism, or organic representative forms", Proc. Liverpool Lit. & Philos. Soc. 14 (1860): 181–216].

Thanks CD for help in selecting a publisher for his book [The naturalist on the river Amazons (1863)].
