Note. — The rock of the Mississippi valley containing the remarkable deposits 

 of galena, (sometimes regarded as the equivalent of the "-Cliff" or •' Upper Mag- 

 nesian " Limestone.',) is considered by James Hall as between the Pludson River 

 and Trenton Groups of New York in age, and as having no representative in the 

 eastern part of the United States. The sandstones and conglomerates of the Lake 

 Superior copper region in Michigan are referred by Foster and Whitney, Hall, 

 Owen and Logan, to the age of the Potsdam sandstone, or the lowest Silurian,', 

 while the copper bearing red sandstone of Connecticut and New Jersey, is shown 

 vy Rertfiold, Rogers andTHall, to be as recent as the Liassic Period.
