JBeautiful green feldspar has been recently found at Bev-

 purple fluor spar are disseminated in its fissures. Edit.

2. Localities of Minerals^ principally in Massachusetts. By 

 Jacob Portek. 



Calcareous tufa, fine, and exhibiting distinct impressions 

 of vegetables, at Semphronius, New York. Dewey. 



Limpid quartz, in good crystals, at Saratoga Springs; al- 

 so at Sand Lake, New York. 



Blue quartz, at Lenox. 



Ferruginous quartz, amorphous and crystallized, at Pitts- 

 field. The colour is yellow, or red tinged with yellow ; the 

 crystals small, well defined, and possessing a strong vitreous 

 lustre. Also at Worthington, often crystallized. 



Fetid quartz, at Lenox and Chesterfield. 



Chalcedony, at Cummington. 



Hornstone, well characterized, at Pittsfield. 



Jasper, generally of a gray or bluish colour, sometimes 

 red, at Pittsfield. Red jasper is also found on the banks of 

 Westfield River at Cummington. 



Prismatic mica, abundant at Chesterfield and Goshen, in 

 granite. It separates very easily into beautiful prisms; the 

 fibres between them, resembling those of the finest amian- 

 thus. 



Black tourmaline, in milky quartz, at Cummington; the 

 crystals are well defined, and uncommonly beautiful, and as 

 l)oth minerals are perfect of their kind, the contrast between 

 the pure white of the quartz, and the long glossy and finely 

 striated crystals of the tourmaline, is very striking. Also at 

 Washington, near Pittsfield. 



Scapolite, of a silver gray colour, associated with qu^rlz, 

 at Chesterfield. The surface of the crystals is longitudinal- 

 ly striated, and generally dull ; but on being broken, they
