Thanks JO for intending to dedicate his The Andes and the Amazon to him.
The discovery of marine shells high up the Amazons CD finds extremely interesting.

Owing to your letter of January the 4
Your discovery of marine shells high up the Amazons possesses extreme interest, not only in itself, but as one more most striking instance how rash it is to assert that any deposit is not a marine formation because it does not contain fossils. Agassiz will not at all approve of this discovery; & if I am not mistaken marine shells have also been found in the large island at the mouth of the river. As for myself I never believed for a moment in Agassiz's idea of the origin of the Amazonian formation.
I shall be very curious to read a full account of the wingless grebe-like bird which you have discovered, & of the great deposit of bones; but I fear of the latter you will not have been able to bring away many specimens.
With my very sincere thanks for the intended honour & for your kind letter, I remain | Dear Sir, | yours very faithfully | Charles Darwin
