Author:  Thomas Henry Huxley
Addressee:  Charles Robert Darwin
Date:  7 July 1857
Classmark:  DAR 11.1: 41a
Letter no:  DCP-LETT-2119

From Asa Gray   7 July 1857

Summary

Believes, with CD, that extinction may be an important factor in explaining plant distributions, but sees no reason why the several species of a genus must ever have had a common or continuous area. "Convince me of that, or show me any good grounds for it … and I think you would carry me a good way with you". It is just such people as AG that CD has to satisfy and convince.

Feels that the crossing of individuals is important in repressing variation and perhaps in perpetuating the species, but instances some plants in which it cannot, apparently, take place.

From Asa Gray   [August 1857]

Summary

States he has "misgivings about the definiteness of species". Believes there is some inherent tendency for plants to originate varieties. Cross-fertilisation is likely in most cases but sees difficulties with plants like Adlumia.

Summary

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)].

From Robert Schlagintweit   25 September 1857

Summary

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].

From T. H. Huxley   [before 3 October 1857]

thumbnail

Summary

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.

Classmark:  DAR 205.5: 218
Letter no:  DCP-LETT-2144

From A. R. Wallace   [27 September 1857]

thumbnail

Summary

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.
