are formed into five species by Boumon, and probably admit of further 
subdivision. The euchroite also belongs to these, and the kupferschaum 
of Werner, at least that from Falkenstein in Tyrol: for some other va¬ 
rieties bearing that name appear to be referable to carbonate of zinc.— 
Arseniate of cobalt, or red cobalt ore, comprising the earthy ( cobalt 
crust ) and the radiated ( cobalt-bloom ) varieties, from Salfeld, Allemont, 
&c .—Arseniate of nickel . 
Case 53. This, and part of the next Case, contain the phosphates : 
among the phosphates of lime may be specified several very scarce and 
interesting crystallizations of Werner’s apatite , such us the large violet- 
coloured crystals from St. Petersburg ; the groups from Ehrenfrieders- 
dorf, Maggia on St. Gothard, Traversella in Piedmont, &c.; the variety 
called asparagus-stone, particularly the specimens from Jumilla in Mur¬ 
cia ; the Norwegian apatite called moroxite; also the phosphorite or fibrous 
and compact phosphates of lime, and the pulverulent variety, known 
by the name of earth of Marmorosh, and which was formerly considered 
as a variety of fluoride of calcium (fluate of lime). —Phosphate of lead, 
or pyromorphite , generally divided into brown lead ore and green 
lead ore: among the varieties of the former, the more remarkable 
are the large six-sided prisms from Huelgoet in Brittany; of the 
latter we have the massive botryoidal ( traubenertz ), the spicular, and 
crystallized varieties, of various shades of green passing into greenish- 
white, into yellow and orange.— Phospharseniate of lead, from Siberia, 
Cornwall, Saxony, &c_ Phosphate of yttria , or phosphyttrite, a very 
scarce mineral substance, first found in the granite of Lindenas in Nor¬ 
way, and subsequently, in equally small quantities, at Ytterby in Sweden. 
-— Phosphate of copper , of which the best characterised species are-— 
the octahedral, or libethenite , from Libethen in Hungary; and the 
prismatic, or rhenite, from Rheinbreitenbach, where it occurs with quartz 
which sometimes passes into calcedony. 
Case 54. Part of this Case is occupied by the remaining phosphates. 
Phosphate of iron , Werner’s vivianite , in variously grouped crystals 
(from Bodenmais in Bavaria, from Cornwall, from Fernando Po, &c.), 
massive and pulverulent: among the specimens of the latter are the 
massive variety of New Jersey, and several earthy blue varieties in clay, 
peat, wood, &c. ; the chalcosiderite of Ullmann, Werner’s green iron 
earth , and Thomson’s mullicite , are likewise phosphates of iron.— Phos¬ 
phate of manganese or triplite, from Chanteloube, near Limoges, in the 
department of Haute Yienne in France, where several other mineral 
substances have lately been found, the essential component parts of 
which are iron, manganese, and phosphoric acid.— -Triphyline, a phos¬ 
phate of iron, manganese and lithia; triplite; delvauxite, &c.— Phos¬ 
phates of alumina, to which belong—the wavellite, a substance which 
was originally mistaken for a hydrate of pure alumina, and therefore 
called hy dr argillite, from Devonshire, Ireland, Brazil, Greenland, from 
Amberg in Bavaria (called lasionite), from Aussig in Bohemia, on sand 
stone, &c.—the klaprothite, called also blue spar, and lazulite, and is 
therefore sometimes confounded with the lapis lazuli in Case 37;—toge¬ 
ther with some other substances of which no exact analyses have as yet 
been published, though they are known to be chiefly composed of alu¬ 
mina in combination with phosphoric acid, such as—the calaite, or real 
turquois (firuzah in Persian), an opaque gem found chiefly at Nisha-
