Miscellaneous Locatities of Minerals. 258, 
sometimes, in bundles and globular masses, and radiating 
from a centre &c. This Mineral Prof. Dewey calls Zeolite, 
but I cannot succeed in forming a jelly with acids.* Proba- 
bly both stilbite and zeolite are found at this locality. 
_ Carb. Lime occurs at the same locality with the two last, 
in six sided tables and six sided prisms, truncated lightly on 
every solid angle. Also in lenticular erystals or thin 
scales, variously grouped. The three last mentioned occupy 
fissures and veinsin the mica slate, about one mile east of the 
meeting house in Chester. This locality is interesting both 
for the minerals, and the situation and relative position of the 
rocks, of which something will be said hereafter. Beryl, 
Norwich, one crystal in my possession, is about five inches 
in diameter, and is intersected on one of its lateral faces by 
another at an angle of about 45°. Likewise found in Ches- 
ter in an aggregate of carb. lime, chlorite and mart A colour 
yellowish green and white. The beryl in Norwich is about 
Ifa mile west from Pitcher’s bridge, near a mass of w 
hite 
rocks, to be seen from the bridge. Prismatic and Tabular 
flat plates in mica slate. Though I do not mention these as: 
Augite is abundant here in amorphous masses. 1 ha) 
foand a few specimens of well characterized sablite and 
coccolite. They occur in beds in the mica slate, both at 
Chester and Middlefield. Magnetic oxyd of. tron is akun- 
dant, disseminated in serpentine, mica slate, &e. ; form, oc- 
taedral crystals and amorphous masses. Bthomt: spar, 
(Middlefield,) in Dolomite or magnesian carb. lime; ws 
‘ains a large proportion of magnesia. I have discov :
