The same method with reference to Linnean genera was pursued by 

 Brisson in his first four volumes as in his last two, with the difference 

 merely that he had not Linne's ed. 10 to consult at the time his first four 

 volumes were printed and he accordingly had no recourse but to take them 

 from the 1748 edition. This matters little, since the genera under dis- 

 cussion are the same in the 1748 edition as in the 1758 edition, except that 

 in some instances a few more species were included in them in 1758 than in 

 1748. These also number 14, which Brisson divided into 33 genera, nearly 

 all of which are still current, many of them with the limitations Brisson 

 originally assigned them. 



The reviewer's "quaint summary" of Mr. Mathews's note on CEnanthe 

 was not intended as a summary of his note, but as a statement of certain 

 conditions in the case, and as such is correct. 



Respecting Marila Oken, and the other Oken genera of 1817, the re- 

 viewer is willing to abide by any ruling of the International Congress 

 respecting them but confesses that his sympathies and inclinations are, 

 personally, with Mr. Mathews.
