are, the splendid groups of limpid prismatic crystals from La Catolica 
in Sicily, accompanied by sulphur ; those from the vicinity of Bristol, 
from St. Beat in the Dep. des Landes; those from Falkenstein in 
Tyrol; from the salt mines of Aranjuez; the acicular variety in the 
hollows of compact sulphate of strontia from Montmartre; in the fissures 
of flint and in chalk, from Meudon ; the radiated and fibrous celestine 
from Pennsylvania, &c. 
Case 55. The whole of this Case is occupied by the sulphates of 
baryta , ( baroselenite or heavy-spar,) among which may be specified the 
splendid groups of straight-lamellar crystallized heavy-spar, especially 
those from Schemnitz in Hungary, and Clausthal in the Hartz, Traver- 
sella in Piedmont, &c. ; the curved-lamella varieties; the columnar, 
resembling carbonate of lead ; the radiated, to which belongs the Bo¬ 
lognese spar , from Monte Paterno, near Bologna, from Bavaria, &c. ; 
the beautiful variety called ketten-spath, or chain-spar, from the Hartz; 
the fibrous and the granular varieties; the compact, called barytic or 
ponderous marble, &c. ; fetid baroselenite or hepatite, an intimate mix¬ 
ture of sulphate of baryta with bituminous matter ; earthy baroselenite: 
—the wolnyne from Muzsay in Hungary, which is only a variety of 
sulphate of baryta. 
Case 56 contains the sulphates of lime , the principal varieties of 
which are,—the selenite or sparry gypsum, in detached crystals and 
splendid groups, from Bex in Swisserland, Montmartre near Paris, Ox¬ 
ford, &c. ; from St. Jago di Compostela, stained by red iron ochre; 
the fibrous gypsum with silky lustre, from Derbyshire, Swisserland, 
Montserrat; the granular gypsum or alabaster ; the compact variety, to 
which belongs the stalagmitical gypsum from Guadaloupe; the scaly 
gypsum (chaux sulphatee niviforme of Haiiy) from Montmartre; com¬ 
mon earthy gypsum, &c.— Anhydrous sulphate of lime, or anhydrite, 
(also called cube-spar and muriacite,) crystalline, fibrous, granular and 
compact; to the last of which belong some of the Italian varieties 
known by the name of bardiglio and bardiglione, as also the singular 
fibrous-compact variety, familiarly called tripe-stone (pierre des trippes), 
from the salt mines of Wieliczka. 
Case 57. Sulphates continued :— sulphate of magnesia, or epsomite, 
generally occurring in crystalline fibres : the fine variety from Calatayud 
in Arragon ; also the haar salz (capillary salt) of Idria belongs to this 
species, and the stalactic cobalt-vitriol, as it is called, from Herrengrund 
in Hungary, which is only sulphate of magnesia, coloured red by oxide 
of cobalt.— Polyhalite, a chemical compound of several sulphates, 
formerly mistaken for anhydrous sulphate of lime: compact and fibrous, 
from the salt formation of Berchtesgaden in Bavaria, and Ischel in 
Austria.— Sulphate of zinc , white vitriol or gallitzinite. — Sulphate of 
iron, green vitriol, or melantherite, (a salt mostly produced by the de¬ 
composition of iron pyrites,) in beautiful large rhombohedral crystals, 
from Bodenmais in Bavaria, and massive, and in stalactic-fibrous forms, 
such as the specimens from the Rammelsberg, in the Hartz, where it 
also occurs in the form of yellow scales, known by the name of misy ; 
and as concretions of a red colour, called vitriol-roth or botryogene : 
the plumose vitriol ( federsalz ), and a botryoidal-reniform substance 
called bergbutter, are nothing but casual mixtures of sulphate of iron and 
hydrous sulphate of alumina.— Sulphate of copper , or copper vitriol :—
