are the lead mines of Derbyfhire, Cardigan- 
fbire and Flintfpire, which have been worked 
for ages, yet fhew no fign of the decline of 
their ftores. | , | 
In all thefe, nature fports with great lux- 
uriancy; the cryftallized lead ore of Tralee *, 
the fibrous lead ore of Tipperary; the lami- 
nated lead ore of Lord Hoptoun’s mines; the 
cryftalized tins, and the figured ores of Zink, | 
are equally noted for their elegance, fcarcity, 
and richnefs. 
The ore of Zink, or Lapis Calaminaris, is 
found ‘in vaft quantities in the counties of 
Somerfet and Plint ; while black lead or wadd, 
a fubftance fcarce known in-other kingdoms, 
abounds in the mountains of Cumberland. 
To the Swedi/b Petroleum, we may oppofe 
the Well at Pztchford, and that of St. Ca- 
‘ therine’s near Edinburgh. Our amber and 
our jet, together with our inexhauftible 
firata of coal found in fo many parts of this 
kingdom, will, in the article of bitumens, 
give us the fuperiority over thefe fo much 
boafted productions of Sweden.
