Chapter I

. and II.--Elevation of the land: equability on E. coast as

shown by terraces, page 19; length on W. coast, page 53; height at Valparaiso, page 32; number of periods of rest at Coquimbo, page 49; elevation within Human period near Lima greater than elsewhere observed; the discussion (page 41) on non-horizontality of terraces perhaps one of newest features--on formation of terraces rather newish.

I believe new. I think the connection (page 54) between earthquake [shocks] and insensible rising important.

## Chapter IV .--The strangeness of the (Eocene) mammifers, co-existing with

recent shells.
