1 am fortunate in being enabled, through the kindness of Mr. Busk, 

 the talented editor of this Journal, to explain the seemingly 

 irregular numbering of the Plates. The 'Journal' is not a Journal 

 exclusively, but consists of three separate works, which are in the 

 course of publication simultaneously, piecemeal, and bound together; 

 in fact, of three stout gentlemen rolled into one. Each work requires 

 a separate series and numbering of Plates, and there were plates be- 

 longing to each work in the number last noticed : the VX Mr. Busk 

 believes a misprint, and thinks it should have been IX.
