appearing like delicate wool or down, display a 
fine iridescent blue, yellow and red tarnish ; red 
antimony , mostly in fine capillary crystals, from 
Braunsdorf in Saxony, and a variety of the same, 
called tinder ore , from the Hartz;— white anti¬ 
mony, formerly considered as a muriate of this 
metal, crystallized, on galena, &c.—specimens of 
antimonial ochre on native and grey antimony, &c. 
(Case 47 and part of 48.) contain the ores of 
cobalt and arsenic. The crystals of glantz-cobalt , 
which has been frequently confounded with white 
cobalt, are mostly from Sweden;—a suite of 
specimens of white cobalt , exhibiting the princi¬ 
pal modifications of crystallized and irregular 
shapes;— grey cobalt , principally from Wittichen 
in Wiirtemberg;—some specimens of oxides of 
this metal, viz. the black and the brown or yel¬ 
low cobalt ochre , the latter of which contains 
iron;—various specimens of the red cobalt ore , or 
arseniate, comprising the earthy (cobalt erasf) and 
the radiated ( cobalt bloom) varieties, from Saal- 
feld, Aliemont, &c. Between these and the re¬ 
maining metallic substances in the adjoining 
table-case are deposited the ores of arsenic; na¬ 
tive arsenic (formerly called testaceous cobalt) in 
reniform and botryoidal shapes, from Andreas- 
berg, &c.;—splendid and instructive specimens 
of the sulphurets of this metal, viz. the yellow 
orpiment , massive, and in separable, striated, 
transparent laminae ; and the red orpiment or re¬ 
algar , perfectly crystallized and massive, and also
