Note 14 — Chapter V · ON THE OLDER TERTIARY FORMATIONS OF PATAGONIA AND CHILE.

Professor H. D. Rogers, in his excellent address to the Association of American Geologists (Silliman’s Journal, vol. xlvii, p. 277) makes the following remark: “I question if we are at all aware how completely the whole history of all departed time lies indelibly recorded with the amplest minuteness of detail in the successive sediments of the globe, how effectually, in other words, every period of time has written its own history, carefully preserving every created form and every trace of action.” I think the correctness of such remarks is more than doubtful, even if we except (as I suppose he would) all those numerous organic forms which contain no hard parts.)
