 publications, and his conversation, an extraordinary 

 power over a multitude of zealous naturalists, be- 

 longing to every part of the world. 



In order to understand more clearly the nature 

 and effect of the reforms introduced by Linnseus 

 into botany, I shall consider them under the four 

 following heads : Terminology, Nomenclature, Ar- 

 tificial System, and Natural System. 



Sect. 2. Linncean Reform of Botanical Termi- 

 nology. 



IT must be recollected that I designate as Ter- 

 minology, the system of terms employed in the 

 description of objects of natural history ; while by 

 Nomenclature, I mean the collection of the names of 

 species. The reform of the descriptive part of botany
