2S. Arsknopyeite or Mispickel. 
It occurs sparingly in North Carolina, and has been observed in minute 
crystals, associated with gold ores, at the Lemmond and Stewart Alines, 
Union county, and at the Barringer Aline, in Cabarrus county. It has 
been found by General Clingman, in Cleaveland county, and by Dr. 
Asbnry, at Ore Knob Mine, in Ashe count}-, the Honeycutt vein at Gold 
Hill, and highly auriferous at the Asbnry Mine, in Gaston county. It 
also occurs near Cooke's Gap, Watauga county, in fine crystalline par- 
ticles, disseminated through siliceous rock. 
29. Nagyagite. 
This exceedingly rare mineral, which heretofore has been known only 
from Transylvania, in Hungary, occurs sparingly in minute crystals and 
foliated particles at the King’s Alountain Mine, where it is associated with 
altaite, gold, etc. 
30. Cove l lite. 
Resulting from the decomposition of chalcopyrite and associated with 
it, covellite occurs at several of the North Carolina copper mines, tor 
instance at the Phoenix Aline, etc , in Cabarrus county ; in fine scales at 
the Gill is Aline,* in Person county. 
3. SuJph a ruenids, /Su/phautimonids, etc. 
31. Proustite(?) 
Microscopic crystals of a bright aurora red color occur with talc, rho- 
doehrosite, etc. at the McMakin Mine. As they are rich in silver they 
are probably proustite. 
32. Aikinite (?) 
A mineral, containing sulphur, bismuth, lead and copper, and there- 
fore probably aikinite, has been observed in small particles in quartz asso- 
ciated with chalcopyrite at Col. White’s Mine, Cabarrus county.
