the latter (as Jeldspath apprej, h\ii is distinct 
from both. * 
(Case 3 .) Among the specimens of chryso- 
beryl or cyraophane may be noticed the North 
American variety, in its matrix of quartz and 
feldspar, with small trapezoidal garnets.—Kyanite 
or disth^ne, massive, in separate crystals, and 
imbedded, with grenatite, &c.: also in small 
polished pieces which are sometimes mistaken 
for sapphires.—A series of crystals of Brasilian, 
Saxon and Siberian topazes, among which 
there are some new modifications ; Saxon va¬ 
rieties, imbedded in the topaz rock, an ag¬ 
gregate of topaz, shorl, quartz and sometimes 
mica.—-Emerald and beryl; several insulated 
crystals of the true emerald from Peru : very 
perfect prismatic crystals in their matrix. Beryls 
of various colours, the most common of which 
is the variety called aquamarine: the fine 
groups of these, found in a ferruginous loam 
at Nerchinsk and Odontchelong in Siberia, are 
very remarkable; beryl (or perhaps pycnite) from 
Limoges in France, and from Rabenstein at 
Twiesel in Bavaria.—Near the beryl, (though 
perhaps not very nearly related to it,) is placed 
the euclase, a rare crystallized mineral substance 
discovered, by Dombey, in Peru.
