1. Notices of two minerals from the Lancaster, Pa. Zinc mines; by 
W. J. Taytor, (from a letter to J. D. Dana, dated Lancaster, Aug. 31, 
1855.)—Allow me to bring to your notice two minerals which | have 
found in very small quantities at the mines of the Lancaster Zinc Com- 
pany, a few miles northwest from Lancaster City, Pa. 
The first one [ will call Tennantite, until I find sufficient of the un- 
decomposed mineral for a thorough quantitative analysis, which will 
decide the matter conclusively 
Color, steel gray. Steaks dark reddish gray. No crystals have 
yet been observed; fracture uneven; cleavage not observable in the 
small pieces found. A qualitative Ganipsin in the wet way showed the 
presence of sulphur, arsenic, copper, iron and zinc 
The second mineral is Buratite or a variety of Aurichalcite. It oc: 
tals also laminated, also forming a coating on the limestone (dolomite) 
and quartz crystals which occur with it. Structure also columnar, 
which shows when broken the same “we appearance. Lustre, 
pearly. Color, verdigris green. B.B. in a matrass gives out water 
hich has neither acid nor alkaline eanGon: and the crystals become 
brownish black. In the inner flame, yellow while hot, and white on 
cooling. With salt of phosphorus, grr gene and affords a green 
glass. With equal quantities of soda and borax a globule of copper. 
Effervesces with HCl, and dissolves entirely. 
he ore from the mines of the Lancaster Zinc Co. is principally 
blende intermixed mechanically ina most peculiar manner with the 
dolomite rock, in which it is found; at and near the surface it has de- 
composed into a calamine, it is interesting to observe the process of 
decomposition very gradually going o 
2. On Singular Cloud-belts, aes in Georgia, on the 13th of June, 
1855; by Wm. G. Wiiuiams, Prof. Nat. Sci., La Grange College, Ala- 
bama. ‘~The avében: or belts of cloud observed in June 13th were seven 
in number, and apprene oe oe beginning at about 9 o’clock in 
the evening. They n by me and others at Decatur, Ga. The 
following facts are fom pee foke - the time. The first or northern 
belt, which may be regarded as the principal one, was first seen at a 
quarter past nine. It had then the form and appearance of a pillar of 
cloud, or of dark smoke extending upward from the horizon ten or fifteen 
degrees north of west, ak a we south of where the sun set about two 
hours previous. At its e it was about two and a half or three de- 
ess wide ; its edges coe poe parallel, but gradually spreading like @
