IV DEDICATION. 



which has dispersed the bigotry of ages and raised your 

 Lordship to your present rank in soeiety : my studies, 

 while they have incapacitated me from making the 

 just distinctions between your Lordship and many of 

 your predecessors, enable me to form a just estimate of 

 that combination of talents which have rendered your 

 Lordship an object of equal admiration to the Politician 

 and the Philosopher. 



To the Patron of Science and the Friend of Man- 

 kind, I inscribe this work, in the fullest confidence 

 that the fame of your Lordship will last as long as the 

 glories of England shall remain the subjects of history 

 or tradition. 



JOHN STEPHENSON. 



London, March, 1832.
