(which enters the composition of cosmetics) and 
the indurated talc: to the former of these may 
also be referred the beautiful green variety from 
Siberia, composed of distinct groups of small 
diverging-radiated laminae.— Fotstone , or ollite, 
the lapis comensis of the ancients, from Como in 
the Milanese, where it is turned on the lathe into 
most durable culinary vessels.—In this case is 
also placed a substance from New York, which 
has very much the appearance of white laminar 
talc, but is a hydrate of magnesia. 
(Case 18 .) contains steatitic substances.— No- 
hle serpentine, which, in combination with primi¬ 
tive limestone, constitutes themarmo verdeantico; 
common serpentine , among the varieties of which 
are best known those from Bareuth and from Zdb- 
litz in Saxony, where they are manufactured into 
vases and various other articles ; serpentine with 
garnets, magnetic ironstone, asbest, slaty talc,&c. 
—Triclasite oxfahlunite , from Sweden and Green¬ 
land. —-Varieties of steatite , amongwhich the most 
remarkable are, that of a yellowish green colour 
from Greenland, and that from Gopfersgriin in 
Bareuth, with small crystals of other mineral sub¬ 
stances, converted into, and forming part of, the 
massive steatite.—To these are added some sub¬ 
stances which are allied to the preceding, though 
differing from them with regard to their chemical 
composition; such as the agalmatolite of Klaproth 
(bildstein of Werner, talc graphique of Haiiy),
