From Daniel MacKintosh   1 December 1867

Summary

Seeks CD’s opinion and references on the causes of terraces in the south of England. He supports sea action as cause, either by currents or on coasts, and has been engaged in a controversy in the Geological Magazine [4 (1867): 571–5] with the subaerial school. Poulett Scrope thinks they are agricultural.

From Daniel MacKintosh   8 December [1867]

Summary

Thanks CD for information on inclined terraces in S. America, which DM thinks applies to the chalk downs of S. England. CD’s definition that the sea widens and fresh water deepens is key to the subject.
