Dana and Chambers on Ancient Sea-Margins. 209 



to narrower examples of the great belting, such as are presented on 

 bolder coasts, we find precise demonstrations, not only of an ancient sea- 

 level about 44 feet above the present, but of several others intermediate 

 between that and the present, particularly at 32, 27, 20, 11, and 8 feet, 

 such appearing in the well-defined form of terraces or benches of land, 

 the unavoidable result of the wearing power of the sea when it abuts 

 against land of suitable slope and consistence ; and, as already almost 

 implied, these memorials of ancient sea-levels conform with each other in 

 various parts of the island." — Pp. 6-9. 



Mr R. Chambers' volume is occupied with details of facts 

 from Scotland and other parts of Great Britain, and after- 

 wards from the continent of Europe, and foreign countries 

 generally. 



A brief abstract is here presented in a tabular form, first 

 of terraces occurring in the vicinity of the sea, and next of 

 those existing in the interior. We have preferred this ar- 

 rangement, which differs from Chambers' own table, for rea- 

 sons mentioned beyond.
