natural history. (Minerals.) [north 
appears to be closely allied to Bournon’s martial arseniate of copper. — 
Arseniates of copper , chiefly from Cornwall, consisting of the foliated 
arseniate or copper-mica , the lenticular arseniate or lentil-ore, and the 
olive-ore of Werner, which are formed into five species by Bournon, 
but their exact composition remains still to be ascertained by exact 
chemical analyses. The euchroite also belongs to these, and the 
kupferschaum of Werner, at least that from Falkenstein in Tyrol : some 
other varieties bearing that name appearing to be referable to carbonates 
of copper and of zinc. — Arseniate of cobalt , or red cobalt ore, com- 
prising the earthy ( cobalt crust ) and the radiated {cob alt-bloom) varieties, 
from Salfeld, Allemont, &c. — Arseniate of nickel. 
Case 57. Among the various phosphates deposited in this Case may 
be particularized — phosphate of iron , Werner’s vivianite, in variously 
grouped crystals (from Bodenmais in Bavaria, from Cornwall, from Fer- 
nando 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 phos- 
phates of iron. — Phosphate of manganese or triplite, from Chanteloube, 
near Limoges, in the department 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. 
- — Triphyline, a phosphate of iron, manganese and lithia ; — del- 
vauxite, &c. — Phosphate of copper, of which the best characterized 
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. — Phosphate of 
oxide of uranium: — the yellow uranite or uran-mica from Autin, 
Limoges, Bodenmais ; and the green uranite, or chalcolite, chiefly 
from Cornwall and Saxony : both of them phosphates of oxide of 
uranium, but distinct by containing, the former a small portion of 
phosphate of lime, and the latter an equivalent portion of phosphate of 
copper. — Phosphate of yttria, or phosphyttrite, a very scarce mineral 
substance, first found in the granite of Lindenas in Norway, and subse- 
quently, in equally small quantities, at Ytterby in Sweden. — Phosphates 
of alumina, to which belong — the wavellite, a substance which was ori- 
ginally mistaken for a hydrate of pure alumina, and therefore called 
hy dr argillite, from Devonshire, Ireland, Brazil, Greenland, from Am- 
berg in Bavaria (called lasionite ), from Aussig in Bohemia, on sand- 
stone, &c. — the klaprothite, called also blue spar, and azurite, and 
is therefore sometimes confounded with the lapis lazuli; — together 
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- 
pur, in the province of Khorasan, Persia, in nodules or as small veins 
traversing a ferrugino-argillaceous rock, and greatly esteemed on ac- 
count of its beautiful blue colour, which will in most cases be sufficient to 
distinguish it both from the blue silicate of copper and from fossil bones 
(particularly teeth) impregnated with blue phosphate of iron or carbonate 
of copper, some of which substances are vulgarly called occidental tur- 
quoises. — The kakoxene, a rare substance of a crystalline diverging-
