In bringing to a close the present series of papers, the author is deeply 

 sensible of their many defects ; and can only crave for them a lenient judg- 

 ment in view of the very difficult nature of the task he attempted, and has 

 throughout conducted, with the sole desire of elucidating truth. Should the 

 undertaking prove a failure, and the meagre results incommensurate with 



the time and labor bestowed, — at least it may be said of him, •' si non 



tenuit, magnis tamen excidit ausis."
