ScHErtirE [p. 347].—F. A. Genth has found scheelite at the Bangle Mine in Gx 
barras Co., and also at pate e mine, Mecklenburgh Co., North Carolina. At the 
former place it occurs in nular masses three-fourths of an inch in diameter it 
has a pale yellowish- brown ate and a distinct octahedral cleavage. Com positon
