XIV PREFACE. 



logical table. It is pernicious, as well as fool- 

 ish, to set them at variance. 



The plates, composed in the first instance 

 to explain the Artificial System of Linnaeus, 

 have been extended much further, in order to 

 afford representations of one or more Genera 

 in each of Jussieu's Orders, or subdivisions 

 of Orders. The figures, numbered in regular 

 succession throughout, are cited in the text, 

 and a full explanation of the whole is sepa- 

 rately given. The volume ends with a com- 

 parison between the Linneean Natural Orders, 

 and those of Jussieu, by which it will be seen 

 how nearly the conceptions of these great men, 

 though not derived from the same principles, 

 agree together. A few speculative remarks 

 close the whole. They may teach the reader 

 to think on the subject, and to judge for him- 

 self hereafter, how far the conjectures or con- 

 clusions, interspersed through the preceding 

 review of Jussieu's Orders, are well founded.
