Delighted that JSH is coming to Down. Sends correct train time.
He was unaware that varieties occurred proportionately more in large genera.
Recommends a work [Leonard Gyllenhaal, Insecta Suecica, 4 vols. (1808–27)] for tabulating varieties.
Lists "close geographical representatives of Europaean species" based on the species numbers [in T. V. Wollaston, Catalogue of the coleopterous insects of Madeira (1857)].
Tabulation of varieties goes on; very important as it shows the branching of forms. Mentions his principle of divergence.
Reports progress of work on the new rooms [at Down].
Some negative results in variety tabulation survey.
Galls on wild carrot.
Gives CD further details of the fertility of the offspring from cross of a yak and Indian cow, the so-called chooboos, whose fertility he has traced to the seventh generation [see Natural selection, pp. 437–8].
On classification and possibilities of a scientific morphology and zoology. CD’s "pedigree business" is important for physiology but has nothing to do with pure zoology any more than human pedigree has to do with the census. Zoological classification is a census of the animal world.
Refers to CD’s letter of "May last". ARW’s views on order of succession of species are in accordance with CD’s.
Disappointed that his paper ["On the law which has regulated the introduction of new species", Ann. & Mag. Nat. Hist. 2d ser. 16 (1855): 184–96] elicited no discussion; now ARW is trying to prove it. Paper merely states the theory.
On black jaguars breeding inter se: ARW has never heard of a parti-coloured one.
Discusses WED’s future education, the work on the extension, and other domestic affairs.
C. F. Ledebour [Flora rossica (1842–53)] particularly useful for variety tabulation. Results generally favourable.
Additions to Down House.
Last two chapters of MS took six months to write.
Huxley and William Sharpey praise JL’s paper [? on Daphnia, Philos. Trans. R. Soc. Lond. 147 (1857): 79–100] at Philosophical Club.
JSH’s Myosotis is beginning to sport. Asks whether some features are not odd.
Sends details on Myosotis sports. Feels sure he could make any flower in some degree monstrous in four or five generations.
Returns some of the systematics books borrowed from JDH. Will now take on A. P. and Alphonse de Candolle [Prodromus].
Arrangements for a visit.
Return of books.
JDH coming to Down.
Discusses the difficulties of breeding mules by crossing canaries and finches.
Writes concerning library books requested by CD.
Describes his work, which demonstrates that hybrids of Cactus are fertile.
Responds to CD’s article on kidney beans [Collected papers 1: 275–7]. Sends beans as evidence of crossing.
