They were at once recognized by Barrande, who called attention to their primordial character, and thus...

In truth, Mr. Hall observes, the carboniferous limestone is one of the most extensive marine formations of the continent, and is characterized over a much greater area by its marine fauna than by its terrestrial vegetation. " The accumulations of the coal period were the last that gave form and contour to the eastern side of our continent, from the Gulf of St. Lawrence to the Gulf of Mexico ; and as we have shown that the great sedimentary deposits of successive...

To it belongs the gold which is found along the Appalachian chain from Canada to Georgia, together with lead, zinc, copper,, silver, cobalt, nickel, chrome and titanium. I have long since called attention to the constant association of the latter metals, particularly chrome and nickel, with the ophiolites and magnesian rocks of this series, while they are wanting in similar rocks...
