saloon. Jated to zeolitic minerals, may be observed the 
Nat.hist, lazulite or lapis lazuli, which furnishes the valua¬ 
ble pigment known by the name of ultramarine ; 
and the hauyne, a mineral so called in honour of 
the celebrated French crystallographer. Interme¬ 
diate between the zeolitic substances and feldspar, 
are placed some mineral species which cannot be 
referred to either of these tribes : among them 
are the meionite and sommite, both from Vesuvius; 
the scapolite , a Norwegian mineral, of which 
several varieties are known under different names, 
such as the vitreous scapolite, the compact and 
the common scapolite (called also wernerite , after 
the illustrious professor of Freiberg) ; the talclike 
scapolite (micarelle of some authors), &c. Also 
the bergmannite , and th efettstein of Werner are 
related to these.—-More closely allied to feldspar 
is the substance from Krieglach in Tyrol, ( Blau - 
spath Wern.) which was formerly considered as a 
variety of compact feldspar ; near which is placed 
the azarite of Vorau and of Salzburg, massive 
and crystallized.—In this glass case also begins 
the suite of specimens o £ feldspar, which is con¬ 
tinued in the next case; specimens of compact 
feldspar, among which are the red variety from 
Sweden, frequently mistaken for hornstone ; the 
weiss-stein of Werner; the feldspath compacte 
tenace of Haiiy, which is the same as the jade of 
Saussure, called by some saussurite, &c. 
(Case 12.) In this glass case are deposited the
