Mount St. Gothard, but not in the valley of Adula, 
from which its name is improperly derived :—-this 
variety when cut en cabochon (such as the stone 
set in a ring) is commonly called moon-stone; 
modifications of crystals of this variety.— Common 
feldspar , variously crystallized and massive, among 
the latter of which may be particularized the fine 
green variety from Siberia, called amazon stone; 
feldspar with imbedded fragments of quartz (graphic 
stone) from Siberia, &c.—To these are added a few 
specimens of disintegrated feldspar, which passes 
into porcelain earth.—The chiastolite or made, 
placed in this table, is referred by Werner to feld¬ 
spar, under the name of hollow spar.— Petalite and 
spodumen or triphane, substances in which lithium, 
a new mineral alkali, has been discovered.— Indian - 
ite, one of the matrices of the common corundum of 
the Carnatic.—As intermediate between the contents 
of this and those of the next case may be considered 
the leucite (amphig&ne of Haiiy), of which several 
varieties are here deposited. 
(Case 13.) is principally appropriated to the sub¬ 
stances of the garnet tribe. Among the more re¬ 
markable varieties of the noble garnet is that in 
curved-lamellar concretions, found massive inGreen-: 
land.—Th epyrope, or Bohemian garnet, in rounded' 
grains, &c. —The common garnet, the predominant 
colours of which are brown and green: among these 
may be mentioned the variety which, from its re¬ 
semblance to rosin, is called colophonite. To this
