Comments on forthcoming edition [7th (1847)] of CL's Principles. Mentions other books relevant to CL's needs by Hooker, H. G. Bronn, Edward Forbes, and J. G. Kölreuter. Discusses his own books on volcanoes and the geology of S. America.
Mentions expected visit to Down by the Lyells.
My dear Lyell,
I was delighted to receive your letter, which was forwarded here to me. I am very glad to hear about the new Edit of the Principles, & I most heartily hope you may live to bring out half-a-dozen more editions. There would not have been such books as d'Orbignys S. American Geology published, if there had been seven Editions of the Principles distributed in France. I am rather sorry about the small type; but the first Edit, my old true-love, which I never deserted for the later editions, was also in small type.— I much fear I shall not be able to give any assistance to Book III; I think I formerly gave my few criticisms, but I will read it over again very soon (though I am slaving to finish my S. American Geolog) & see whether I can give you any references.—
I have been thinking over the subject, & can remember no one book of
consequence, as all my materials (which are in an absolute chaos on separate bits of
paper) have been picked out of books not directly treating of the subjects you have
discussed, & which I hope some day to attempt: thus Hooker's Antarctic
Flora, I have found eminently useful & yet I declare
I do not know what precise facts I could refer you to. Bronn's Gesichte (which you once borrowed) is the only systematic book I have met
with on such subjects; & there are no general views in such parts, as I have
read, but an immense accumulation of references, very useful to follow up, but
not credible in themselves;—thus he gives hybrids from ducks & fowls
just as readily as between fowls & pheasants! you can have it again, if you
like.— I have no doubt Forbes essay, which is I suppose now fairly out, will
be very good under geographical head. Koelreuter's
German Book is excellent on Hybrids, but it will
cost you a good deal of time to work out any conclusions from his numerous details. With
respect to variation, I have found nothing, but minute details scattered over scores of
volumes.— But I will look over Book III again: What a quantity of work you
have in hand! I almost wish you c
You have pleased me much by saying that you intend looking through my Volcanic volume:
it cost me 18 months!!! work & I have heard of very few who
has read it; now I shall feel whatever little (& little it is) there is
confirmatory of old work or new will work its effect & not be lost. I wish my
S. American volume was out for same end, & I daresay you will be
heartily glad it is not, for you must with all your work in hand, grudge time for your
own new materials. I sh
I return home on Tuesday, having been here for a week to see my Father: Emma &
the children have been having colds but are otherwise well.— I hope you found
I must go to work to proof-sheets: my vol will be about 240 pages, dreadfully dull yet much condensed: I think, whenever you have time to look through it, you will think the collection of facts on the elevation of the land & on the formation of terraces pretty good.
Goodbye with many thanks for your letter & my kindest remembrances to

- f4 990.f4The third volume of Lyell's previous edition (C. Lyell 1840a) contained an extended discussion of the transmutation and first appearance of species (chapters 1–11). CD's copy is lightly annotated (Darwin Library–CUL).

CD's frequent citations in the Origin and later works make clear that Joseph Gottlieb Kölreuter's work was one of CD's major sources on hybridism and an important influence in the development of his theory. DAR 116 contains CD's abstracts and notes on thirteen papers by Kölreuter.
