 all these improvements, and to have attempted to 

 elucidate them by all that has been done by others, as 

 Ventenat, Salisbury, Link, and especially by Mr. 

 Brown and Prof. DeCandolle, would have been quite 

 beyond the scope of the present publication. Such a 

 task indeed could be undertaken by Jussieu himself 

 alone, who has now for 30 years bent all his attention

 which they are disposed by their Cotyledons is given, 

 as avowedly artificial. The terminations of the names 

 of the Orders, which are French, are according to 

 the more recent plan of Jussieu and his followers. 

 For instance, Convolvulace'es, Convolvulacece, and 

 Cislinees, Cistinete, instead of Convolvuli and Cisti.

The question of the natural or artificial character 

 of Jussieu's System has been ably discussed by the
