2296 Miscellaneous Localities of Minerals. 
In looking, a few months since, over the minerals which he 
had previously collected, the writer recognised the following : 
1. Nacrite, on quartz and carbonate of lime, Smithfield, 
from the seams of the Dexter lime rock, (mentioned in his 
catalogue as talc.) He has since obtained some beautiful 
specimens, in small globular masses, on crystallized quartz 
and calcareous spar, and on brown spar, composed of brilliant 
pearly lamine, radiating from the centre. 
9. Brown Spar, at the same place.’ The planes of the 
crystals, which are brown and opaque, are curved, and the 
edges bent up, like those of a hat. Sometimes these crystals 
are covered promiscuously with minute transparent crystals 
of calcareous spar, their length being about six times their 
diameter. 
3. Green earth. On the banks of a creek, between South- 
bury and Woodbury, Con. the writer collected a green sub- 
stance, which on examination was found to be green earth 3 it 
is abundant. 
4. Amethyst. A considerable quantity of detached, imper- 
fect crystals, of a pale colour, and seldom transparent, has 
been found in Voluntown, Con., in the alluvial bank of a 
creek, which was excavated for the wheel ofa mill, belong- 
ing to Capt. Robbins, about ¢ of a mile from his tavern, on 
the road leading from Chestnut-hill to Stonington. 
5. Actynolite. Very beautiful actynolite was discovered 
Jast autumn, in Cranston, R, I. about halfa mile north of the 
iron ore bed, in the woods, on Mr. Nicholas’s farm. It is 
found in fragments mostly covered with earth, which appears 
to have been thrown out, and the rock blasted, many years 
since, in making an excavation. Some masses consist of dis- 
tinct brilliant crystals in talc ; other masses consist of pure 
fine crystals, of glassy actynolite, radiating from centres, of a 
deep greencolour. ‘This locality was kept very secret, until it 
became known this summer, when the proprietor, finding so 
many anxious to obtain specimens, concluded it must be very 
valuable, and the replies of some, that good returns had been 
received for what had been sent to New-York, confirmed him 
in his belief, and determined him to secure a part of the pro- 
fits to himself, by charging most extravagantly. This circum- 
stance shows the impolicy, as well as the impropriety of de-
