Case 54. This, and part of the next Case, contain 
the phosphates : among the phosphates of lime may be 
specified several very scarce and interesting crystalliza¬ 
tions of Werner’s apatite , such as the large violet co¬ 
loured crystals from St. Petersburg; the groups from 
Ehrenfriedersdorf, 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 phos¬ 
phorite 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 hr own 
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 ( trauben-ertz ), spicular, and crys¬ 
tallized 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 Lindenas in Norway, and sub¬ 
sequently in equally small quantities at Ytterby in Sweden. 
— Phosphate of iron , Werner’s vivianite , in variously 
grouped crystals (from Bodenmais in Bavaria, from Corn¬ 
wall, and from Fernando Po), 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, 
and Werner’s green iron earth , are likewise phosphates 
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 compo¬ 
nent parts of which are iron, manganese, and phosphoric 
acid.— Phosjrfiate of copper , of which the best cha¬ 
racterized species are — the octahedral , also called 
olive malachite , from Lebethen in Hungary; and the 
prismatic , called pseudomalachite , from Rheinbreiten-
