W. E. Hidden — Sperrylite in North Carolina. 383 



Sperrylite has been found at four new places in the Cowee 

 Valley up to the present time, namely, at two gravel excava- 

 tions just west of the locality above described and at two 

 similar places east, but all are along the bed of the " Caler 

 Fork " of Cowee Creek and are embraced within a distance of 

 one and one-half miles. 



Another new locality of sperrylite and one of very decided 

 promise was found last summer two miles southwest, in a small 

 valley, but this occurrence will be duly described in an article 

 soon to appear in this Journal descriptive of the minerals of 

 " Mason's Branch" in this same county. 



In conclusion the author wishes to express his thanks to 

 Professor Pentield for his kindness in making the micro-chem- 

 ical and crystallographic examinations which were so essential 

 to the positive identification of this rare and interesting 

 mineral.
