Pebas fossils, p. 282.—In a letter to the author, Mr. Darwin says: "Your discovery of marine shells high up the Amazon 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. As for myself, I never believed for a moment in Agassiz's idea of the origin of the Amazonian formation."1

Agassiz believed the Amazonian formation was formed from glacial deposits from the Andes. Agassiz and Agassiz 1868, pp. 250, 411, 424.
