SALOON. 
Nat. Hist. 
The pycnite, referred by Werner to the beryl; 
under the name of shorlous beryl, and consider¬ 
ed as a variety of topaz by Hauy, is here placed 
between those two species.—Also the pyrophysa- 
iite 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 of Hauy), a remarkable 
specimen of which, both with regard to form 
and volume, is here preserved: it was presented 
by the King of Ava, to the late Colonel Syrhes, 
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; and from Massachusets in North Ameri¬ 
ca ; the flesh coloured tourmaline from Rozena in 
Moravia, (which is by some considered as a varie¬ 
ty of pycnite), &c.—Varieties of common shorl. 
(Case A.) 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. ; 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
