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 galliizinite _ 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
