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 fer sulfur4 h6pa- 
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 crystalli¬ 
zed in six-sided prisms.—Oxides of iron : mag¬ 
netic iron stone, massive, of various grain, com¬ 
pact, crystallized, in serpentine, chlorite slate, 
&c.; ore which yields the wootz, a very hard 
kind of iron ; magnetic iron sand. 
(Case 38). Oxides of iron continued.—Spe 
cimens of specular iron or iron glance, among 
which these 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, 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, &e.— 
The different varieties of compact red iron stone, 
and of red hematite.
