Sir— 
I have discovered a new locality of the green intnoral; of 
which a notice was published in the last number of you 
journal. It isin Amherst. This mass is much larger than die 
one first found, and differs from it in being more uniformly 
coloured, not having whitisly or yellowish spots distributed 
through it, and, likewise. in being of a deeper color. I bave 
noticed, likewise, that, in a single place, it passes into com- 
mon quartz. From the appearance of this mass, I think 
there is no doubt of its being the hornstein eccailleux of 
Brochant, which he describes as sometimes bordering on 
chalcedony. 
In Belchertown, I have found very handsome Amethyst, 
contained in a rounded mass, about 18 inches in diameter, 
composed “of imperfect, prismatic crystals of an extraor- 
dinary size, which shoot out from a quartzy gangue, con- 
taining galena, blende and copper pyrites. Many of these 
crystals terminate in regular pyramids at the surface. But 
just previous to their termination, the amethyst passes 
through them in a vein from one to two inches in width; 
and below the vein, are zigzag striae of milky quartz, hed 
render many of the crystals very beautiful. 
{n the town of Oakham, fine specimens of Adaluria may 
be obtained in great abundance. It is sometimes found in 
six-sided prisms, which are several inches in diameter. 
1. ance at Littleton, (Mass.) in a lime-quarry, own- 
ed by Mr. Wheeler. It is very abundant, and occasionally, 
Gaiely Sivelteed. 
Vitreous Black Ox. Iron, at the South Hampton Lead 
Mine. It is usually found investing carb. lead. It pos- 
sesses a high vitreous lustre. It does not melt before the 
blow pipe; but immediately becomes strongly magnetic.
