very closely allied to the garnet tribe, the stauro- 
lite (called grenatite in Switzerland); besides se¬ 
veral varieties of the cruciform and other crystals 
fromBritany, we have modifications of the simple 
crystals in mica-slate from St. Gothard, accompa¬ 
nied by prisms of kyanite perfectly similar to 
those of the staurolite, and sometimes longitudi¬ 
nally grown together with them. 
(Case 14.) Contains the chrysolite and olivine 
(peridot of Haiiy), the former crystallized and in 
cut and polished pieces ; the latter as grains, in 
basaltic rocks and separate : among these is some 
of the olivine like substance found in the cells of 
the Siberian meteoric iron (Case 32).—The sub¬ 
stances which have been described under the names 
of thallite, arendalite, akantikone, delphinite, are 
Haiiy’s epidote , and Werner’s pistacite : of which 
several specimens are deposited in this case 
Among these is also the violet manganesiferous 
epidote , referred by some to the ores of manga¬ 
nese.— Zoisite. — A finite, variously crystallized, 
from Dauphine, &c.—The pyroxene tribe, com¬ 
prizing the augite , in separate crystals and imbed¬ 
ded in Yesuvian lava, together with groups of 
well defined crystals from Arendahl in Norway, 
where this substance occurs in primitive rocks, and 
the granular augite or coccolite ; the variety of
