ticed ; among which were, beautiful specimens of prekmte, 
from Newark, second mountains, Scotch plains, &c. imbed- 
ded in greenstone. Some were almost of an emerald 
green. Fibrous zeolite, from Patterson, associated with 
greenstone. White stilbite, in compressed four-sided 
prisms, acuminated by four planes. ‘These crystals were 
attached to prehnite, which was traversed by crystals of 
zeolite, from Scotch plains ; fibrous malachite, from Schuy- 
ler’s mine, New-Jersey ; compact peat, from the vicinity of 
Elizabethtown. 
Dr. Torrey read an analysis of the fibrous sulphate of ba- 
rytes, lately found at Carlisle, Schoharie county, N.Y. The 
first public account of this mineral appeared in the Albany 
Gazette, Nov. 14, 1818, when it was announced as celestine 
or fibrous sulphate of strontian, though it had been known, 
and had circulation a year or two before. Dr. Torrey dis- 
covered the mistake soon after, though his analysis was not 
complete until February, 1819. This mineral so much re- 
sembles sulphate of strontian, that the mistake was natural. 
Its real nature however is very apparent when subjected to. 
a few chemical experiments, especially when the sp. gravity 
is ascertained (4.320.) ‘The fibrous sulphate of barytes an- 
alyzed by Klaproth (Analy. Essays, 2. p. 227) appears to 
be a very different variety from the mineral in question, and 
a very new variety should receive a name, we may retain 
that given to it by Mr. Eaton. ‘The very remarkable char- 
acter of the Carslile mineral is, that it does not decrepitate 
in the least before the blowpipe. 
As an analysis of this mineral, which agrees very nearly 
with that of Dr. T’. has been lately published by Professor 
McNeven, of New-York, it will hardly be necessary to 
make any further remarks on this subject. [For its geolo- 
gical situation, &c. see No. 5 of this Journal.—Eb. | 
Mr. Pierce communicated a well characterized specimen 
of kaolin, which he found in considerable quantities near 
_Weekawken, New-Jersey. This substance resulted from 
the decomposition of a secondary stratum, consisting of 
feldspar and quartz underlying greenstone. It was slightly 
fused by a blowpipe heat, in w which it differs from the kao- 
hn of France. ‘This circumstance is probably owing to the
