Summary

Did not intend to imply that Hallett said variation stopped, but that it arrives at a point where further accumulation in direction sought is so slow as to result practically in fixity of type – but not absolute fixity.

Duke of Argyll has requested JDH to superintend publication of a flora of India. JDH thinks he [Argyll] is paying him off for his kick at natural theology.

Willy [Hooker] returning from New Zealand.

A unique character in Drosophyllum.

Sees no reason for CD to contribute to Ross and Faraday memorials.

Summary

Recounts the trip back from St Petersburg – visits to botanic gardens and museums throughout Western Europe.

Pleased that CD admired Bentham’s address [see 6793]. JDH had read it in MS and modified some very heterodox passages about insularity. CD has hit the flaw in it.

F. A. W. Miquel is a convert.

Summary

Drosophyllum plants recovering [from trip]. Describes experiments on them.

Summary

Thanks GC for his assistance. "The data for all that I have to say about the Scotch deer-hound are, owing to you, almost sufficient; and much better data than I have got in many other cases." [See Descent 2: 260.]

Believes Dr Stirling would be compelled to admit some change in "the famous protoplasm in our domestic races, both in regard to the structure of the body & qualities of the mind".

Summary

Thanks GM for offer of observations. Would be interested to know when the horns of merino rams first appear,

and has long wished for living specimens of Drosophyllum.

Summary

Describes how the offer of C.B. was made. He declined a knighthood. Murchison and Lyell are trying to get him made Knight Commander of the Star of India, but he does not think there is a chance. The Duke [of Argyll?] might do it, but does not like JDH’s Darwinism.

Next Presidency of Royal Society discussed: all (Brodie, the X Club botanists, et al.) are agreed on Lyell.

Everyone is disappointed with Nature.

What did CD think of "Huxley’s rhapsody on Goethe’s ditto" [Nature 1 (1869): 9–11]?

Summary

Envies JDH’s Russian trip.

Thanks for information on Aucuba. Urges him to experiment – case "has highest physiological importance, not to mention Pangenesis".

Has heard that Huxley has been attacking views of Sir W. Thomson.

Has received 12 plants of Drosophyllum lusitanicum from Oporto.

Summary

Orchids translation should goad [French] Academy into electing CD.

JDH will be sent to St Petersburg congress by Government.

Huxley on protoplasm; his address to Geological Society.

Fertilised an Aucuba with pollen of various species. Reports on results.

Summary

Further comments on arrangements for German translation of their joint paper.

Summary

Thanks for specimen of Drosophyllum.

Describes capacity of various plants to catch flies.

Cannot name fern specimen.

Laugher pigeon descended from Columba livia.

Discusses tailless dogs.

Believes astronomical phenomenon responsible for oscillation of level of earth’s crust.

Would WCT like copy of Orchids?

Expected plants [Drosophyllum] have arrived.

Summary

An article in North British Review by mathematician against Hooker and Huxley and for William Thomson [P. G. Tait, "Geological time", North Br. Rev. 50 (1869): 406–39]. Feels a conviction that world will be found older than reviewer makes it.

Article on "Design" [by J. B. Mozley] in Quarterly Review [127 (1869): 134–76].

Has JDH studied Drosophyllum?

Summary

Honoured to be mentioned with Alexander von Humboldt, who was an inspiration to him.

Summary

Will do his best on the tooth [sent by CD] but does not put much weight on conclusions based on a single tooth of a horse.

Darwin attacked by three clergymen at BAAS meeting [Exeter, 1869].

Summary

Reports on the differences of growth and development of plants of three species grown at Geneva from seed collected at different localities. Forwards seed for CD to plant and observe differences in development.

Carl Linsseer has published a memoir on the times of flowering, foliation, etc. of diverse species in different parts of Europe [Mem. Acad. Imp. Sci. St.-Pétersbourg 7th ser. 11 no. 7 (1868)] and concludes that the northern forms are more forward and that this is hereditary. AdeC’s experiments carried out on annuals, show only the effects of heredity; probably the direct action of physical conditions affects development, at least in perennial species.
