Tin, although universally known in the metallic state as 

 obtained from its ore^ would never be recognizable without 

 experience in the crystallized oxide, from which it is chiefly 

 procured. This crystal was once thought, by the Cornish 

 miners, to be destitute of metal. The tin mines of Corn- 

 wall are the most famous in the world, and were very early 

 known. The Phoenicians procured this metal from thence.
