NATURAL HISTORY. 
[long 
Bournon, and probably admit of further subdivision. To 
these also belongs the kupferschaum of Werner, at least 
that from Falkenstein in Tyrol: for some other varieties 
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 Sal- 
feld, Allemont, &c.— Arseniate of lead from Cornwall,Nert- 
chinsk in Siberia, Johanngeorgenstadt in Saxony, &c. 
Case 54. This, and part of the next Case, contain the 
phosphates : among the phosphates of lime may be speci¬ 
fied several very scarce and interesting crystallizations of 
Werner’s apatite , such as 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 Murcia; the Norwegian apatite 
called moroxite ; also the phosphorite or fibrous and com¬ 
pact 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, gene¬ 
rally divided into brown lead ore and green lead are: 
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 ( trauben - 
ertz), the spicular, and crystallized varieties, of various 
shades of green passing into greenish-white, into yellow 
and orange.— Phosphate of yttria, or phosphyttrite, a very 
scarce mineral substance, first found in the granite of Lin- 
denas in Norway, and subsequently in equally small quan¬ 
tities at Ytterby in Sweden.— Phosphate of iron, Werner’s 
vivianite, in variously grouped crystals (from Bodenmais 
in Bavaria, from Cornwall, and from Fernando Po), mas¬ 
sive 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 Ull- 
mann, Werner’s green iron earth, and Thomson’s multifile, 
are likewise phosphates of iron.— Phosphate of manganese 
or triplite, from Chanteloube, near Limoges, in the depart¬ 
ment of Haute Vienne in France, where several other mineral 
substances have lately been found, the essential component 
parts of which are iron, manganese, and phosphoric acid.
