 French writer : this has been obviated, by uniting his trees 

 with middle-sized and small flowers, under Mr. Robertson's 

 division of small-sized flowers. 



The subject of Mr. Robertson's communication, as well 

 as the comparison of his system with that of the French

 elucidated ; the chief difference between them is in the pre- 

 ference given by Mr. Robertson, in the formation of his 

 Classes, to the glands, rather than to the quality of the fruit.

 (in order to facilitate the ascertaining the place of any un- 

 known individual) ought to be founded on properties which 

 are more lasting as well as most obvious, the preference, in 

 this case, ought surely to be given to those which are 

 annexed to the foliage.
