The introductory matter of this work is unmistakably "Napoleonic''; the text is apparently 

 from the hand of the more conservative and trustworthy author. — There is a reprint of the 

 "Introduction " in Jard. Gontr. Cm.. 1851, pj). 27-47 — though one issue of this matter might 

 have been considered amply sutlicient.
