this and the feldspar of the contiguous opposite 
glass case, is placed the andalusite, which was first 
considered as a congener of the former and after¬ 
wards referred to the latter (as feldspath apyre ), 
but appears to be distinct from both. 
(Case 3.) Among the specimens of chryso- 
beryl or cymophane may be noticed the North 
American variety, in its matrix of quartz and 
feldspar, with small trapezoidal garnets.—Kyanile 
or disthene, massive, in separate crystal, 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 varieties, 
imbedded in the topaz rock, an aggregate of topaz, 
shorl, quartz, and sometimes mica.—Emerald and 
beryl : several crystals of the South American 
emerald, insulated and in their matrix; emeralds 
from Salzburg. Beryls of various colours, the 
most common of which is the variety called aqua¬ 
marine : the fine groups of these, found in a ferru¬ 
ginous loam at Nerchinsk and Odontchelong in 
Siberia, are very remarkable; large crystals of 
emerald or beryl from Rabenstein in Bavaria, 
and from Limoges in France.—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. ■—
