in some other countries, still they are occasionally found 

 both in this country and in Ireland : in the latter. Silver 

 is found in considerable abundance, in the Copper Ores of 

 Muckruss, on the lake of Killarny. 



Zinc is obtained in vast quantities from the mines of 

 Somerset and Fiintshires, and Black Lead or Wadd, (a 

 substance of rare occurrence in other countries) abounds 

 in the mountains of Cumberland ar.d Derbyshire. Nor 

 are other mineral substances wanting, our exhaustless 

 strata df Coal, our Mines of Allum and Rock Salt; our 

 Quarries of Marble and Stones of various kinds, our Clays 

 and Earths are incontestable proofs of the intestine riches 

 of Great Britain." 



Of the Fossil remains of organized bodies so Humerously 

 and widely dispersed through this kingdom, some are 

 found imbedded in rocks and stones, others in matrices 

 of clay and earth, some are found at the greatest depths our 

 miners have yet explored, others again only on the summits 

 of our highest mountains ; they are most numerous on 

 chalky and hilly districts, and amongst shingle on the sea 

 coasts : numerous valuable species are often obtained, in the 

 excavation of wells: they principally consist of various 

 species of Echineae, Shells, Crustaceae, and the teeth, tusks, 

 horns or bones of animals, the species of which are not 

 clearly defined, or are entirely unknown in the recent state. 



The curiosity so deeply implanted in the mind of man^ 

 and which so frequently renders him restless and uneasy, 

 unless engaged in exploring unknown paths, often occasions 

 subjects of real insrinsic value^ but of easy acquisition,
