3. The variety examined by BERZELIUS was massive, and came froi 

 the cobalt. mines of Loos in Helsingland, Sweden : that above describe 

 as crystallized, is found among the old ores from the mine Albertin- 

 near Harzgerode in the Hartz. It is accompanied by Spathic Iron, Ca 

 careous Spar, Fluor, Quartz, Galena, and Copper Pyrites.

1. Heated in a matrass, it yields moisture, and becomes of a dark( 

 shade of color. Upon charcoal, before the blowpipe, it smells of ars< 

 nic ; and when submitted to the inner flame, it yields a metallic globul 

 which contains this metal.
