According to Mr CHILDREN, it contains water, oxide 

 of cobalt, lime, arsenic acid, and magnesia. Before the 

 blowpipe it gives off water and becomes black. It imparts 

 a blue colour to borax and salt of phosphorus, and is en* 

 tirely soluble in muriatic acid. It occurs at Schneeberg in 

 Saxony, disposed on rhombohedral Quartz, and was for- 

 merly considered as a variety of the prismatic Cobalt-mica, 

 but seems rather to belong to the order Haloide.
