DEDICATION. XI 



mittingly received encouragement and sup- 

 port, to a degree of which I am unable to 

 express my feehngs. 



I trust I shall be forgiven, when I add, 

 that I am the more flattered by your Lord- 

 ship's approbation, from a conviction, that 

 the good opinion of one so eminently qua- 

 lified to judge of the subject, will, in the eye 

 of the world, give a sanction to the inven- 

 tion, which I could not have ventured to 

 hope for from any exertions of my own. 

 Allow me, therefore, to subscribe myself, 

 with respecjt and gratitude. 

 My Lord, 

 Your Lordship's much obliged, 



and obedient Servant, 



WILLIAM MOORCROFl'- 



Oxford Street, 

 March 25, 1800.
