Analcime, among the crystallized varieties of which saloon 
are remarkably large specimens of the trapezoidal Na ^h’ ist 
modification .—-Chabasite or chabasie, in groups of 
primitive rhombohedral and modified crystals. 
{Case 11.) Continuation of zeolitic substances : 
■— prehnite, crystallized and massive, the grass- 
green variety of which, discovered in South Africa 
by the Abbe Rochon, has been mistaken for chry¬ 
solite, chrysoprase, and even emerald. To this 
belongs also the koupholite; and the substance 
known by the name of Chinese jade, (or stone 
You, see Room I., table 7.) may perhaps likewise 
be referred to prehnite. — Harmotome, or cross 
stone, both in simple and cruciform crystals, from 
Oberstein,Strontian, andAndreasbergin theHartz, 
which last locality has procured to this substance 
the names of andreolite and hercinite.—Among 
those substances deposited in this case which are 
in some respects related to zeolitic minerals, may 
be observed the lazulite or lapis lazuli, which fur¬ 
nishes the valuable pigment known by the name of 
ultramarine; and the hauyne, a mineral so called 
in honour of the celebrated French crystallogra- 
pher. Intermediate 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 Ve¬ 
suvius ; the scapolite, a Norwegian mineral, of 
which several varieties are known under different 
names, such as the vitreous scapolite, the compact
