To Charles Lyell   29 [December 1859]



My dear L.

You are the man to do work. I am not at all sure what sort of note you required about Blyth, but I enclose one which you could forward.—1 I have written it splendidly well! If you wish a more formal one I would write it, but then you must tell me how to address it; but I think a note from you with this enclosure would be more effective. It is very good of you to take so much trouble.— I wrote also to Col. Sykes.—2

I suspect article in Times must be Huxley’s.3 I have not had time to read that in Daily news,4 which some one (perhaps you) has sent me.

I had a civil note from Chambers himself, saying that he has given brief abstract in his Journal.5

I was much surprised (& said so to Owen) at finding the passage in your Book6

I have not alluded to supposed British Trias Mammal.7

Of course I by no means believe that the mundane Glacial period destroyed all Tropical production, though probably it destroyed many.— I believe the vegetation on the plains was at that period like (as I just allude to but as usual far too briefly) that described by Hooker at foot of Himalaya, in which truly Tropical & Temperate forms now live mingled together. This shows at least possibility of so unexpected a mixture.—8 I could have added another instance from part of Mexico.—9

Anything on earth that I can do in giving references &c &c will be a real pleasure & duty.

Yours affecty | C. D.

Had letter this morning from poor Dana at Florence, telling me that my caution to him not to work too hard has proved true—is quite disabled in his head.10 Hopes to come to England.
