SALOON. 
Hjst, 
The pycnite, referred by Werner to the beryl, 
under the name of shorlous beryl, and consider¬ 
ed as a variety of topaz by Hatiy, is here placed 
between those two species.—Also the pyrophysa- 
lite from Fahlun in Sweden, considered by the 
same crystallographer as a variety of topaz.— 
This case also contains the tourmaline and com¬ 
mon shorl. Among the varieties of the former 
may be specified the rubellite, also called si- 
berite, (tourmaline apyre Ha'uy), a remarkable 
specimen ot which, both with regard to form 
and volume, is here preserved : it w'as presented 
by the King of Ava, to the late Colonel Syraes, 
when on an embassy to that country, and after¬ 
wards deposited by the latter in Mr. Greville’s 
collection. Other red and blue varieties from 
Siberia; that from Rozena in Moravia, which is 
by some considered as a variety of pycnite, &c. 
—Varieties of common shorl. 
{Case 4 .) In this and the following case are 
arranged the substances belonging to the species 
of quartz.—Rock crystal: various modifications 
of its crystalline forms; small, dodecahedral 
and other crystals known by the trivial names of 
Gibraltar diamonds, Bristol diamonds, &c. j va¬ 
rieties of colour, according to which the crystals 
obtain the vulgar denominations of smokey topaz 
or morion, cairn-gorm, citrine, &c.; specimens of 
rock
