48 Miscellaneous Localities of Minerals. 
« Purple Copper, at Chesterfield, (Mass.) It occurs in 
cay wonniities in the same. rock with the green feldspar. 
4. Pinite, beautiful specimens of this mineral have re- 
cently been found in Lancaster, (Mass ) by Mr. Charles 
Stedman of that place. It occarred imbedded in quartz, 
at one spot, and at another, in porphoritic granite. It is 
crystallized in six-sided prisms, terminated by planes.. The 
solid angles, and the terminal edges of these crystals are 
often replaced by planes; and the lateral edges in some in- 
stances, from numerous truncations, are entirely effaced, the 
erystals becoming cylindrical. ‘Their predominating aspect, 
however, is a four-sided, rectangular prism, owing to an 
undue extension of four sides of the primitive form. These 
crystals, although easily broken in almost any direction, 
separate best in directions parallel to their bases. They 
vary In magnitude, from two inches to three fourths of an 
inch in length, and from one to one third of an inch in 
diameter. They present several colors. Those of a dark 
brown, tinged with green, and the red are the most abun- 
dant. Their lustre is hkewise very various. Some. are 
almost dull, while others are quite glimmering. Th 
dark colored crystals are opaque, but thsahighe ghter are trans- 
lucent. When reduced to a powder, and moistened BY 
the breath, they emit a strong irolieooe odour.
