17 
crystals of Brasilian, Saxon, and Siberian topazes^ 
among which there are some new modifications; 
Saxon varieties, imbedded in the topaz rock, an ag¬ 
gregate 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 co¬ 
lours, the most common of which is the variety 
called aqua-marine: the fine groups of these, found 
in ferruginous loam at Nerchinsk and Adontche- 
long in Siberia, are very remarkable; large crystals 
of emerald or beryl from Limoges in France, and 
from Babenstein in Bavaria, the latter accompanied 
by tantalite:—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.— Hhe pycnite, referred by Wer¬ 
ner to the beryl, under the name of shorlous beryl, 
and considered as a variety of topaz by Haiiy, is 
here placed between those two species.—Also the 
pyrophysalite from Fahlun in Sweden, considered 
by the same crystallographer as a variety of topaz. 
—This case also contains the tourmaline and com- 
mon skorl. Among the varieties of the former may 
be specified the riibellite^ also called siberite (tour¬ 
maline apyre of Haiiy), a remarkable specimen of 
wLich, both with regard to form and volume, is 
here preserved: it was presented by the King of 
Ava to the late Colonel Symes, when on an embassy 
c to
