Cuprite—The red oxide of copper, crystallized in the form of 
minute octah ining small cavities in a light brown coloured 
siliceous veinstuff. 
Bouenoumala. Balade and Sentinelle Mines. 
Tile Ore.—This, the earthy variety of red oxide of copper, occurs 
at the Balade and Sentinelle Mines. The specimens received 
from Mr. Pryor are mixed with streaks of the green carbonate of 
copper. 
Tenorite.—The black oxide of copper occurs at the Balade mine 
in the form of a loose black powder intimately associated with 
copper pyrites. 
Sulphate of Copper.—From the Balade Mine, where it is met - 
with on the outcrop of the lode in the form of beautiful pale blue 
crystals—some distinct ; but in other specimens the crystals are 
very small and arranged in mammillated aggregations. . 
Malachite.—The green hydrated carbonate of copper; most of 
the specimens from the Balade mine merely show it as a coating, 
or sparingly diffused through the mica-schist ; some are more 
massive, but friable and more or less earthy, but none sufficiently
