52 Miscellaneous Notices of American 
about three and a half inches long by one and a half in di- 
ameter. 
We have other specimens from Virginia: one was re- 
ceived from the late R. P. Barton, Esq. through Mr. John 
Grammer, Jr. It is six inches long by one inch in diame- 
ter: its form is that of a prism of six sides. It is from the 
Shannondale sulpbur springs ; found in the bottom of them, 
near the Shenandoah River. It is found near considerable 
masses of lime stone: the crystals occur in groups which 
appear to shoot ‘from a matrix of clay, marl, and calca- 
reous earth.”’ ) 
We have also received similar specimens from the same 
place, from Mr. Sanford I. Ramey, of the Senior Class in 
Yale College. 
Crystals of gypsum occur in clay near Hudson. (Mr. 
Curtiss.) 
Native Yellow Oxid of Tungsten.—We have omitted, for 
some time, to mention a fact which we ascertained a year 
or two since; namely, the existence of the ore mentioned 
above, which we suppose to constitute a new species. 
It occurs incrusting the ferruginous tungsten of Mr. Lane’s 
mine, and occupying the cavities. {tis not abundant. It 
is insoluble in acids, but readily dissolves in ammonia, from 
which it is precipitated by acids, white, becoming yellow. 
Tantalite in Haddam rocks.—Dr. Torrey writes, that a _ 
specimen of the granite of Haddam, Connecticut, which he 
sent to Count Wachtmeisten of Stockholm, has recently 
been examined by Professor Berzelius, and found to con- 
tain éantalite, in a state resembling that of Finbo in Swe- 
den. The Haddam mineral occurs crystalized in small 
prisms in the same rock with the chrysobery]. 
The Chrysoberyl of Haddam.—The genuineness of this 
mineral has been admitted by Hauy, Jameson, and other 
distinguished mineralogists to whom specimens have been 
sent; but Dr. Torrey writes—‘‘ The mineral! found in the 
eranite of Haddam, which is generally supposed to be chry- 
soberyl, and which I sent to Professor Germar of Halle, for 
examination, he thinks is a new variety of beryl. The 
specific gravity is only 2.7. Before the blow-pipe it melts
