PREFACE. 



bation evidently bestowed upon the last edition, 

 from its translation into our own language, into 

 Spanish, French, English,* Dutch, and Russian ; 

 not to mention other proofs of its favourable 

 reception. I have endeavoured, therefore, to 

 enrich it not so much with an addition of pages, 

 as of various matter ; to arrange the heads in a 

 more natural order ; and to render the whole as 

 useful to students as possible. 



September 10, 1810. 



* I am unable to discover any English translation besides my 

 own, which was first published in 1815. J. E.
