mispickel), the sulphuretsof iron, viz. th e common, 
smooth and striated; the radiated pyrites, a sub¬ 
stance very subject to decomposition,and to which 
belong most of the varieties of what is commonly 
called lenticular and coxcomb pyrites, as also the 
, globular pyrites of a radiated texture. 
(Case 37.) Sulphurets of iron continued 
The hepatic or liver pyrites of Werner, very dis¬ 
tinct from what French mineralogists call fer 
sulfure hepatique, which latter 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.—The re¬ 
mainder of this table-case is occupied by part of 
the oxides of iron : magnetic iron-stone , massive, 
of various grain, compact, crystallized, in serpen¬ 
tine, chlorite slate, &c.; ore which yields the 
voootz, a very hard kind of iron from the East 
Indies ; magnetic iron sand , &c. 
(Case 38 and part of 39.) Oxides of iron 
continued : specimens of specular iron , or iron 
glance, among which those from the island of 
Elba are remarkable 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 (in the 
next table-case) ; among the most remarkable 
specimens of which is that in delicate, trans¬
