Has at last received first letter CGE wrote.
More specimens being sent.
Sends his sketch of paper ["Fine dust in the Atlantic Ocean" (1846), Collected papers 1: 199–203].
D'Orbigny considers Pampas clay deposit result of debacle. CD cannot doubt it is slow, estuary deposit. Would be grateful for information on this point.

I waited until I had a packet ready, before writing to thank you much for the copies of
your communications to the Berlin academy & for your obliging letters, for which
I feel truly thankful: I have at last received the first letter you
I have enclosed a copy of a little Paper, which I thought of sending to
Taylor's Journal; I think it will modify some of your
opinions on the origin of the Dust; its [illeg] origin you will see, has been
long out of the question: what great strata, abounding with Infusoria, must be now
depositing at the bottom of the Atlantic; how curious, their aërial origin! I
have sent specimens from four other stations: that numbered (3) is what you have already
examined. Would you kindly take the trouble, the next time you send anything to England
to return me my little Paper; & if you will send me any Abstract of the contents
of packets 184.108.40.206. I w
Might I beg, as a great favour, that you would just look at the specimens of a white deposit which is of vast extent in Patagonia, between the fossiliferous tertiary strata & the overlying gravel: I have not seen any deposit quite like it & am very curious to know its nature, as I am now drawing up a short volume on the geology of S. America.—
Have you yet had time to look at any of the Pampas clay; M: Al: d'Orbigny
considers it due to a debacle & of some considerable antiquity; I, on the other
hand, cannot doubt that it is a slow, estuary deposit, contemporary with recent species
of Mollusca, but with extinct species of Mammifers: would the Infusoria throw any light
on this? I sh
With my sincere thanks for the great honour you have done me, in the manner in which you have referred to me, I have the pleasure to remain. Your's faithfully & obliged | Charles Darwin.
Might I take the liberty of asking you, the next time you see
I hope you will accept from me, a copy of my small volume on Coral Reefs, which I have
directed my Book-seller to send to the care of M

This did not appear in Richard Taylor's Annals and Magazine of Natural History but in the Quarterly Journal of the Geological Society. CD's notes and another manuscript copy of the paper are in DAR 188.
