It is evident from this table that the Lower Palaeozoic and 

 Eozoic formations in the Maritime provinces much more closely 

 resemble those of Great Britain than those of the inland parts 

 of Canada and the United States ; though they also resemble the 

 rocks of New England and the Eastern Appalachian region 

 generally, as well as those of some parts of Eastern Quebec. 

 The succession deduced from the study of the inland continental 

 plateau is thus incapable of being applied successfully to that in 

 the sea-coast where great igneous actions were going on upon 

 the Atlantic margin of both continents, contemporaneously with 

 tranquil deposition of ordinary aqueous beds on the interior 

 submerged plateau.
