saloon, fibrous varieties; the red compact variety, by 
Nat. Hist, some called crocalite, &c.—The natrolite of Klap¬ 
roth, of which a few specimens are added, is by 
some considered as a variety of mesotype.— 
Stilbite , mostly crystallized : among the colour¬ 
ed varieties is the red from Fassa (fassaite). 
—Apopliyllite , some varieties of which have 
been mistaken for mesotype and stilbite.— Anal - 
time, among the crystallized varieties of which 
are remarkably large specimens of the trapezoidal 
modification.— Cliabasite 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 chrysolite, chrysoprase, and even emerald. 
To this belongs also the koupholite of Vauquelin, 
and probably also the iiarphoUte of Werner. The 
substance known by the name of Chinese jade 
(or stone You , see Room I table 70 may per¬ 
haps likewise be referred to prehnite.— Harmo - 
tome, or cross stone, both in simple and cruci¬ 
form crystals, from Oberstein, Strontian, and 
Andreasberg in the Hartz, which last locality 
has procured to this substance the names of an- 
dreolite and hercinite.'—Among those substances 
deposited in this case which are in some respects 
related to zeolitic minerals, may be observed the 
lazulite or lapislazuli, which furnishes the valuable 
pigment known by the name of ultramarine; 
and
