Down. | Bromley. | Kent. S.E.
My dear Lyell
I have been very much interested by your long letter (to be forwarded tomorrow);1 but these subject have so much gone out of my head that I have nothing to suggest.2
I cannot think much of the absence of organic remains.3 There were none in the vast gravel beds of Patagonia with sea-shells on surface; & none in the till of T. del Fuego, also with shells on surface;4 though it may have been that these till beds were formed when T. del F. was like Greenland & afterwards subsided.— Yet I confess from what little I have of late read of Greenland I have suspected what you seem now inclined to admit & what Chambers so vehemently urges.5 Is it certain that abundance of sea-living & swimming animals is any guide to shells &c living at the bottom? I cannot think that animals could live where icebergs are habitually grounded. I have remarked on this in Geolog. Transact Vol. VI p. 421,6 but I refer to this only because a statement by Wrangell seems interesting on the tranquil space of shallow sea within that where the icebergs ground.7
With respect to former state of England, the Boulder which I describe at height of 803 ft in middle of Staffordshire has always seemed to me a striking case: it is in my paper on Glaciers of N. Wales in the Phil. Mag. 3d series Vol. XXI. p. 186.—8
I pity you having to alter & modify on this great subject: I always marvel at & admire your industry & care.—9
I wish this note was better worth sending. I grieve over poor dear Glen Roy.—
Ever yours | C. Darwin
