 INSTRUCTION to Ladies and Gentlemen ; and from his extensive collection, comprising 

 many thousand specimens, persons are enabled in a dozen or twenty lessons to acquire 

 sufficient knowledge to identify all the ordinary components of crystalline and volcanic 

 rocks, and most of the minerals and metals used in the arts.
