lenticular and coxcomb pyrites, as also the glo¬ 
bular pyrites of a radiated texture.—The hepatic 
or liver pyrites of Werner, very distinct from 
what French mineralogists call/er sulfur^ h^pa- 
tique, 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 in six sided 
prism.—Oxides of iron; magnetic iron stone, 
massive, of various grain, compact, crystallized, 
in serpentine, chlorite slate, &c. ; magnetic iron 
sand. 
[Case 34.) Qxides of iron continued.—Speci¬ 
mens of specular iron or iron glance, among 
which those from the island of Elba are remarka¬ 
ble 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 belongs 
partly to this species, partly to the scaly red and 
brown iron ore ; among the most remarkable spe¬ 
cimens of which is that in delicate, transparent, 
tables of a blood red colour, from Nassau-Siegen ; 
that in scales coating the cells of lava, See .;— 
the different varieties of compact red iron stone, 
and of red hematite.
