CAOUTCHOUC MINERAL. (See Bitumen.) 

 CAPILLARY PYRITES. Capillary Chlorone- 

 Py r ite s. 



Delicate, capillary crystals. 



Lustre metallic. Color brass-yellow, inclining to bronze-- 

 yellow and steel-grey. 



1. Before the blow-pipe, it melts into a brittle metallic globule ; it col- 

 ors glass of borax, violet-blue. In nitric acid, it is dissolved without 

 leaving a residue, forming a pale green solution.
