Many curious marbles are also found in New 

 Spain, and in North America. The chief quar- 

 ries in the territories of the United States are at 

 Stockbridge, and Lanesborough, Massachusetts; 

 sundry places " in Vermont and Pennsylvania ; 

 Amenia, in New York ; and in Virginia : some 

 of which fully equal the finest specimens from 

 Europe f . At Marble Town, near Hudson river,

This division has scarcely been observed by 

 mineralogists, except in a few instances. Accord- 

 ing to Werner's system, it must chiefly belong to 

 the transitive, and the floetz or horizontal rocks. 

 Some few examples have been already mentioned 

 of very compact ancient marbles, with a fine frac- 

 ture like the argillaceous substances, such as the 

 palombmo, and that which resembles ivory. That! 

 called Greek, and the ancient black and yellow, 

 also approach to this division.
