Discovery of Yenite. 51 



Notice of a locality of Yenite in the United States. Bv 

 John Torrey, M. D. Read Nov. 24, 1823. 



A few days since, the Hon. Samuel Eddy, of Providence, 

 Rhode Island, presented me an uncommon mineral for exami- 

 nation, with permission to publish my remarks, should the 

 substance prove to be interesting. 



It was found at Cumberland, in Rhode Island, in small crys- 

 tals, imbedded in an aggregate of quartz and epidote. The 

 crystals vary in size. The largest found by Mr. Eddy was an 

 inch and a quarter in length, one quarter of an inch broad, 

 and about two lines in thickness. The terminations are want- 

 ing. Its form is nearly rectangular ; the surface striated and 

 shining, with a semi-metallic lustre. Cross fracture somewhat 

 resinous. It is imperfectly foliated in the direction of the 

 longer diagonal of the prism. It scratches glass slightly. It 

 is opaque, and of a blackish brown colour. The powder has 

 the colour of the mass. Specific gravity 3.6. 



Before the blow-pipe it melted with great ease into a black 

 opaque glass, which was strongly attracted by the magnet. 



Some crystals were found almost acicular, traversing the 

 quartz in every direction. 



From all these characters, I have no doubt the mineral is 

 Yenite ; a species which has not hitherto been known to 

 exist in America. In justice, however, to my friend Pro- 

 fessor Dewey, of Williams College, I must here state, that in a 

 letter 1 lately received from him, he mentions having just ex- 

 amined a mineral from Connecticut, which he believes to be 

 Yenite. A detailed account and analysis of this, will soon be 

 forwarded to the Lvceum.
