called lenticular or coxcomb pyrites, as also 
the globular pyrites, of a radiated texture;— 
hepatic or liver pyrites (very distinct from the 
fer sulfure hepatique of some French mine¬ 
ralogists, which is decomposed common and 
radiated iron pyrites, and sometimes brown 
iron stone);— magnetic pyrites, which is nearly 
allied to the preceding species: massive and 
crystallized in six-sided prisms.— Sulphuret of 
cobalt , from Bastnaes in Sweden.— Sulphuret of 
nickel , formerly called capillary iron pyrites, 
and afterwards considered as native nickel, till 
its real composition was determined by Arfved- 
son. 
Case 6 . Sulphuret of copper , or vitreous cop* 
per , variously crystallized, foliated, compact, See. 
to this are also commonly referred the second¬ 
ary fossils, known by the name of Frankenberg 
corn ears , which occur in the bituminous marl- 
slate of Frankenberg in Hessia, and are princi¬ 
pally composed of vitreous and grey copper.— 
Sulphuret of copper and iron , to which belong 
the yellow copper or copper pyrites , including 
the pale yellow fine-grained variety, called he- 
matitiform or blistered copper pyrites ; and the 
variegated copper ore (buntkupfer-erz), dif¬ 
fering from the former in the proportions of its 
constituent parts, and easily known by the red¬ 
dish colour of its fractural surfaces; crystallized, 
massive, and foliated.
