Nat. Hist. 
(Case 37.) Ores of iron continued :— radiated 
pyrites of Werner (fer sulfure blanc Hauy) a 
substance very subject to decomposition : to this 
belong most of the varieties of what is called len¬ 
ticular and coxcomb pyrites, as also the globular 
pyrites of a radiated texture.—The hepatic or 
liver pyrites of Werner, very distinct from what 
Trench mineralogists call fer sulfure hepatique, 
which latter is decomposed common and radiated 
iron pyrites and sometimes brown iron stone.— 
Magnetic pyrites , which is nearly related to the 
preceding species ; massive and crystallized in 
six-sided prisms.—Oxides of iron : magnetic iron 
stone , ltiassive, of various grain, compact, crys¬ 
tallized, in serpentine, chlorite, slate, &c. ; ore 
which yields the wootZy a very hard kind of iron ; 
magnetic iron sand. 
(Case 38.) Oxides of iron continued.— Speci¬ 
mens of specular iron , or iron glance, among 
which those from the island of Elba are remark¬ 
able on account of their beautiful iridescence and 
play of colours ; variety in large laminar crystals, 
appearing like polished steel, from Stromboli, &c .; 
the micaceous iron ore of Werner, belonging 
partly to this species, partly to the scaly red and 
brown iron stone ; among the most remarkable 
specimens of which is that in delicate, transparent 
tables of a blood red colour, from Nassau-Siegen ; 
that in scales coating the cells of lava, &c.~The
