to the tongue. G.=2°80. Soluble only in sulphuric acid. An 
analysis gave SO, 34°50, AlO, 45°00, FeO, 1:25, H,O 19°25=100. 
This affords the formula AlSO,+3H,0; or like aluminite except 
in the smaller amount of water. Found near the city of Cha- 
chapoyas. 
Maltinowskite.—A variety of tetrahedrite. An analysis of the 
mineral from the district of Rocuay gave 8 24:27, Sb 24°74, As 
056, Pb 13-08, Cu 14:37, 11°92, Fe 9°12, Zn 1°92=100. 
Other analyses of the same mineral from the mine of Carpa agree 
closely with this. It occurs massive, and has a gray color an 
metallic luster.
