referred the olivine, which, in its purer state, is denominated chrysolite 
or peridot, and when protoxide of iron is predominant, has, by some, 
been called hyalosiderite. ^ 
Case 26. Silicate of zinc, called smithsonite (after the ingenious 
chemist who first distinguished its nature, and that of silicates in <r ( ._ 
nerai), and also electric or siliceous calamine, the finest specimeniTof 
T thos ® fron J Siberia and Hungary; the variety called willemile, 
from Aix-la- Chape lie. — Silicate of manganese, of which there are 
several varieties (some of them only mechanical mixtures of this silicate 
of carbonate of manganese, and quartz), which have received particula^ 
names, such as allagite, rhodonite, &c. —tephroite — Silicate of cerium or 
cerite, from Bastnas, Sweden. —Silicate of iron, to which'belono- the 
hisingente ,sideroschiz olite, chlorophcdte, chloropal, stilpnomelane, qillin- 
gite, fayahte, anthosidente, and some other newly discovered mineral 
substances. Silicate of copper, or siliceous malachite, also called chrv- 
socolla and copper-green : to which may be referred the dioytase or 
copper-emerald, a scarce mineral from the Kirguise country in Siberia. 
Silicate of bismuth, also called bismuth-blende and eulytine, found in 
the form of hair-brown globules, at Schneeberg, Saxony Silicate of 
zircoma, to which belong Werner’s common zircon and some hyacinths 
of jewellers, from Ceylon, Auvergne, Chili, the Lake Ilmen in Siberia - 
alsp the blue zircon from Vesuvius ; the variety called zirconite from 
j ei . arr l ln Norway, and the ostranite from the same locality, 
and differing from zircon only by its inferior hardness ;-the malacon , 
or hydrous zircon.— To these is added the thorite of Berzelius, from 
Brevig m Norway, a new mineral in which fhe metal thorium was first 
discovered — Silicate of alumina .* of these we have the andalusite, 
the kyanite or disthene, and the related mineral substances called silli- 
manite; xanthite, worthite, bucholzite, and fibrolite (one of the con- 
f, 0m ‘ ta ,y substances of the corundum of the Carnatic) the allophane, 
the halloysite, lenzmite, scarbroite, collyrite , bole, and some minerals of 
similar aspect are also referable to the silicates of alumina; and amono- 
these may be particularized the catlinite or Indian pipe-stone from the 
quarry of Coteau des Prairies, brought from thence by Mr. Catlin, the 
first white man allowed by the Indians to visit it, and after whom the 
substance was named by Dr. Jzckson-agalmatolite ( Werner’s bildstein, 
with which various other substances have been confounded) employed 
by the Chinese for carving images, vessels, &c. 
The Silicates with several bases are under arrangement in a series of 
Cases, nearly m the following order : 
Cases 27 to 29 contain zeolitic substances : apophyllite, or ichthy- 
ophthalmite m > fine crystals, from Hesloe in Faroe'; with stilbite; 
with tessellite of Brewster; with poonalite of Brooke, &c. ; a variety of 
apophylhte, called albine by some mineralogists ; —chabasite or chabasie, 
in groups of primitive rhomboidal and modified crystals ;— the variety 
called haidenite from Baltimore ; — mesotype from Auvergne, Faroe, 
&c., to which are also referred the natrolite of Klaproth, °the needle- 
stone of Werner, the scolicite , the mesolite, krokalite, &c. ; anal- 
cime, among the crystallized varieties of which are remarkably larce 
specimens of the trapezoidal and other modifications from Fassa 
m Ivrol -stilbite and heulandite, or foliated zeolite in splendid speci- 
mens from Iceland, Faroe, and Scotland;— brewsterite; — laumontite or
