with an inclination of seventy-two degrees. This 
mine is famous for producing fine cabinet specimens 
of lead. 
At Bleyberg, in the duchy of Carinthia, in Ger- 
many, there is a mine well known for the yellow 
lead which it produces, as well as for the singular 
disposition of its veins, which, to the number of 
fourteen, are ranged one upon the other, with an 
equal number of calcareous layers between them. 
These last are almost full of shells, and compose 
the beautiful shining marble called lumachelle. At 
Tarnowitz, in the principality of Oppeln, in Silesia, 
there is a mine in which the veins are disposed in 
a similar manner, resting on thin horizontal layers 
of marble mixed with fossil shells, black earth, and 
asphaltum. 
The principal lead-mines in Spain are situated in 
the granite hills of the province of Jaen, and in the 
jurisdiction of the little town of Canjagar. 
The other quarters of the world are by no means 
so rich in lead as Europe. Patrin remarks that in 
Northern Asia the Uralian mountains, which form 
such an immense chain, extending from north to 
south at least five hundred leagues, rich in copper 
and iron, contain only one mine of lead. Again, 
the vast chain of Altaic mountains, which separate 
Siberia from Chinese Tartary, and which are yet 
more considerable than the others, produce no more, 
though they abound in mines of copper, gold, and 
silver. 
The uses of lead are too well known to require
