into a milk-white enamel, and besides it is entirely too soft 
for chrysoberyl.” 
In reply to Dr. Torrey, we remarked, that we imagined 
the mineral examined by Professor Germar could not be 
the crystalized chrysoberyl of Haddam, whose character we 
suppose to be unquestionable. We suggested, that it might 
be a compact granular mineral, occurring in the same rock, 
and which we suppose may be beryl in mass. 
Dr. Torrey again writes that he believes the mineral 
which he sent to Professor Germar, was not crystalized : 
that the latter remarked, it should perhaps be called gran- 
ular beryl, and that it is doubtless the massive mineral to 
which we alluded. 
It has been already mentioned in this article, pa. 37, that 
ihe chrysobery! has been recently found at Saratoga. We 
would mention also, that there is a locality of it in Haddam, 
east of the river, and different from the one usually visited. 
We had specimens from Dr. Dart, two or three years ago, 
but cannot name the precise spot. 
Plumbago from North Carolina.—It is of a very fine 
quality, and appears well adapted both for crayons and 
pots. It occurs a few miles north of Raleigh, and exists in 
great quantities. It has long been used in the vicinity as a 
pigment. We are indebted for this information to the 
Hon. Judge Johnson, of the Supreme Court of the United 
States; and also for the most beautiful yellow ochre, from 
the waters of the Oconee in Georgia, and for a handsome 
fine grained greyish white marble well polished. This is from 
the waters of Broad River in South Carolina. Both the 
last are abundant. 
Chromat of Iron.—A compact specimen, said to be chro- 
mat of iron, has been handed to us by John Wales, sq. It 
is from Wilmington, Delaware, but not having examined it 
chemically, we cannot answer for its genuineness. 
Micaceous Iron—Of extreme beauty, is found a few miles 
from Northampton. It has a high lustre, and is contorted 
with delicate flexions, as if it had lain between the layers 
of mica slate, which we presume must have been the fact. 
Dr. Hunt and Mr. W. C. Dwight of Northampton, have
