3. It occurs in the same repositories as Blue Malachite, with which it 

 is frequently associated. Beautiful varieties of Green Malachite are 

 found at Chessy in France, in Siberia, and at Moldavia in the Bannat of 

 Temeswar. The compact Malachite is chiefly found at Schwatz in Ty- 

 pol. Green Malachite occurs in Cornwall, Cumberland and Wales, 

 England. 



It is found in the United States, at several places, though no whe 

 very handsome specimens. The most interesting localities are in Mary- 

 land, in the Blue Ridge in Pennsylvania near Nicholson's Gap, and at 

 the Perkiomen Lead Mine, and in New Jersey at Schuyler's mines, 

 where it is accompanied by Red Copper-Ore.

 snuffboxes, ring-stones and other ornaments. Others are used as pig-
