the ferruginous tungsten of Mr Lane’s Mine, and occupying 
the cavities. It is not abundant. It is insoluble in acids, but 
readily dissolves in ammonia, from which it is precipitated by 
acids, white, becoming yellow.— -/d. 
45. Tantalite in Haddam Rocks.-^-'Dr Torrey writes, that a 
specimen of the granite of Haddam, Connecticut, which he sent 
to Count Wachtmeister of Stockholm, has recently been exa^. 
mined by Professor Berzelius, and found to contain tantalite ^ 
in a state resembling that of Finbo in Sweden. The Haddam 
mineral occurs crystallised in small prisms, in the same rock 
with the chrysoberyk— /d. 
46. The Chrysoberyl The genuineness of this 
mineral has been admitted by Haiiy, Jameson, and other dis- 
tinguished mineralogists, to whom specimens have been sent ; 
but Dr Torrey writes : “ The mineral found in the granite of 
Haddam, which is generally supposed to be chrysoberyl, and 
which I sent to Professor Germar of Halle, for examination, he 
thinks is a new variety of beryl. The specific gravity is only 
^.7. Before the blowpipe it melts 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 exa- 
mined by Professor Germar could not be the crystallised chry- 
soberyl of Haddam, whose character we suppose to be unques- 
tionable. 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 crystallised : 
that the latter remarked, it should perhaps be called Granular 
Beryl, and that it is doubtless the massive mineral to which we 
alluded. The chrysoberyl has been recently found at Saratoga. 
We may 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.— /d.
