As this work is the refult of many years appli- 
cation and a<5lual experience, and contains, as I 
believe, much new and original matter, I am willing 
to flatter myfelf that it will prove neither ufelefs nor 
unacceptable to my readers. 
The fuccefs of my endeavours is the befl: plea for 
my prefuming to fubmit this performance to their 
perufal : And as I have had the good fortune to 
receive your Grace’s approbation in almofl; every 
ftage of this undertaking, I venture to communicate

me to entertain.
