with green and blue carbonates of copper; the 
tine light blue variety, coloured by copper, &c. 
the black lead ore of Werner, which appears to be 
merely a variety of the white lead ore.—Phosphates 
of lead, which are divided by Werner into brown 
lead ore and green lead ore. Among the speci¬ 
mens of the brown phosphate , the most remarkable 
are the large sixsided prisms from Huelgoet in 
Britany, &c. 
(Case 43.) Ores of lead continued green 
phosphate , massive, botryoidal, spicular, &c. $ 
variously crystallized $ of various shades of green, 
passing into greenish white, into yellow and 
orange ; with ferruginous quartz, straight foliated 
barytes, &c. from Scotland, Freiberg in the Bris- 
gau, &c. ; arseniate of lead.— Molybdate of lead , 
or yellow lead ore ; massive, lamelliform, and crys¬ 
tallized ; on compact limestone, &c. chiefly from 
Bleyberg in Carinthia.—The specimens of chro¬ 
mate of lead , or red lead ore, deposited in this 
case, are particularly beautiful and instructive ; 
the accompanying substances are green lead ore, 
and sometimes small greenish brown crystals of a 
substance, the component parts of which are tlic 
oxides of lead and of chrome : the gangue stone, 
in which the red lead occurs in the gold mines of 
Beresof, is a kind of micaceous rock mixed with 
particles of quartz and brown iron stone.—In this 
case is also placed an interesting suite of crystals, 
fit that most rare substance the murlo-carbonate 
of
