substance, called keffekilliie by Dr. Fischer, who dis¬ 
covered it in the Crimea ; —serpentine^ the purer va¬ 
rieties of which (generally hydrates) are called noble 
serpentine : they constitute, in combination with pri¬ 
mitive limestone, the verde antico and some other fine 
green marbles; — the marmolite of Hoboken in New 
Jersey likewise belongs to it. Among the varieties of 
the common serpentine, those from Bareuth and from 
Zbblitz in Saxony are best known, where they are ma¬ 
nufactured into vases and various other articles; ser¬ 
pentine with imbedded garnets, magnetic iron-stone, 
asbest, &c.—With these is also placed the olivine , 
which, in its purer state, is denominated chrysolite or 
peridot , and when protoxide of iron is predominant, 
has been called lujalosiderite. 
Case 26. Silicate -of zinc, called also electric or si¬ 
liceous calamine, the finest specimens of which are those 
from Siberia and Hungary.— Silicate of manganese , of 
which there are several varieties, (some of them only 
mechanical mixtures of this silicate, carbonate of man¬ 
ganese, and quartz,) which have received particular 
names, such as allagite, rhodonite, &c.— Silicate of 
cerium or cerite , from Bastnas, Sweden.— Silicate of 
iron , to which belong the hisingerite, sideroschizolite, 
and chlorophasite.— Silicate of copper , or siliceous ma¬ 
lachite, formerly called chrysocolla, and copper green ; 
to which is also referred the dioptase or copper eme¬ 
rald, a scarce substance from the Kirguise country in 
Siberia.— Silicate of zirconia, to which belong Wer¬ 
ner’s common zircon and some hyacinths, from Ceylon, 
Auvergne, Chili, the Lake Ilmen in Siberia:—and the 
variety called zirconite from Friedricksvarn in Norway, 
&c.;—the blue zircon from Vesuvius.— Silicate of alu¬ 
mina , to which belongs the hyanite or disth^ne, and a 
variety of it from Connecticut, called sillimanite. As 
appendix to these, the remainder of the table-case is 
to contain the varieties of lithomarge , (now placed in 
Case 25,) fuller s earth , hole , scarhroite , haloisite , &c.. s
