SECT. CCL. 
With fulphurated iron, Cobaltum ferro 
fulphurato miner alifatum. 
This is of a lighter colour than the pre- 
ceding, nearly like to tin or filver. It is 
found 
a, Criftallifed. 
I. In a polygonal form. 
a. Of a flaggy texture. 
b. Coarfe- grained. 
This kind is found in Baftnas- 
grufva at Riddarfliyttan in Weft- 
manland, and difcovers not the 
leaft mark of arfenic. The coarfe- 
grained becomes flimy in the fire, 
and flicks to the flirting 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 
A6]:s of the Swedifh Academy of 
Sciences for the year 1746. Both 
fhefe give a beautiful colour.
