SALOON, lours which it exhibits) are several from the tran- 
Nat. Hist, sitiou Syenite of Laurwig in Norway.—The adu- 
laria (which stands in the same relation to com¬ 
mon feldspar as rock crystal to common quartz) 
is principally found on Mount St. Gothard, but 
not in the valley of Adula, from which its name 
is improperly derived:—this variety when cut^TZ 
cabochon (such as the stone set in a ring) is com¬ 
monly called moon-stone ; modifications of crys¬ 
tals of this variety.— Common feldspar, variously 
crystallized and massive, among the latter of 
which maybe 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 spe¬ 
cimens of disintegrated feldspar, which passes 
into porcelain earth.—The chiastoUte or made, 
placed in this table, is referred by Werner to 
feldspar, under the name of hollow spar.— Ice^ 
spar,—PetaJite and spodumen or triphane, sub¬ 
stances in which lithium, a new mineral alkali, 
has been discovered.— Indlanite, one of the ma¬ 
trices of the common corundum of the Carnatic. 
— Albite, —As intermediate between the con¬ 
tents of this and those of the next case may be 
considered the leiicite (amphigene of Haiiy), of 
which several varieties are here deposited. 
Case 13 is principally appropriated to the 
substances of the garnet tribe. Among the more 
remarkable varieties of the noble garnet is that in 
curved lamellar concretions, found massive in 
Greenland.
