12. — The Acadian Basin in American Gteology. 

 By L. "W. Bailey, Esq., Geological Survey of Canada. 



THE Acadian Basin, embracing the region bordering on and 

 including the Gulf of St. Lawrence, together with the pro- 

 vinces of New Brunswick, Nova Scotia, Newfoundland, and Prince 

 Edward Island, constitutes one of the natural physical divisions of 

 the continent of North America, and exhibits many marked 

 peculiarities of climate and floral and faunal distribution. In its 

 geological structure, and in the history which this reveals, its in- 

 dividuality is not less clearly marked, being often in strong contrast 

 with that of other portions of the continent farther west; and in 

 some periods and features even exhibiting a closer relationship with 

 the geology of Europe. In the present paper, the facts bearing upon 

 this individuality are summarised and discussed; including the con- 

 sideration of the varying land- surfaces of Acadia in different eras, 

 the time and nature of its physical movements, its climate and its 

 life. A review of recent progress in the investigation of its geolo- 

 gical structure is also given.
