152 DESCRIPTIONS OF MINERALS. 
Ods. Leadhills, Wanlockhead, and othcr lead mines of 
Europe are foreign localities. In the United States, very 
handsome crystallized specimens occur at King’s Mine, in 
Davidson County, N. C.; other localities are the Perkiomen 
and Phoenixville mines, Pa. ; the Lubec lead mines, Me. ; 
lteniox,) N. NCS ; formerly, a mile south of Sing Sing, } N. Y.; 
and the Southam pton lead mine, Mass. 
The name pyromorphite is from the Greek pur, fire, and 
morphe, form, alluding to its crystallizing on cooling from 
fusion before the blowpipe.
