2. With fulphurated iron, Cobaltum ferro 

 fulphurato miner ali fa turn. 



This is of a lighter colour than the pre- 

 ceding, nearly like to tin or filver. It is 

 found 

 a. Criflalliied. 



1. In a polygonal form. 



a. Of a flaggy texture. 



b, Coarfe-grained. 



This kind is found in Baftnas- 

 grufva at Riddarfhyttan in Weft- 

 manland, and difcovers not the 

 lead mark of arfenic. The coarfe- 

 grained becomes flimy in the fire, 

 and fticks to the ftirring hook dur- 

 ing the calcination, in the fame 

 manner as many regules do •, and 

 is a kind of regule prepared by 

 nature. 



That fort of a flaggy texture is 

 very martial, and is defcribed by 

 the mine-mafter Mr. Brandt, in the 

 A3.s of the Swedifh Academy of 

 Sciences for the year 1746. Both 

 thefe give a beautiful colour.
