PREFACE. 



This Pamphlet has been written with the object of supplying, 

 to Students of Medicine, a ready means of acquiring that 

 special information which, heretofore, they had much trouble 

 and attendant loss of time in searching for through cumbrous 

 works on the subject. Charts are the usual vehicles employed 

 for conveying this kind of information, but the want of porta- 

 bility materially lessens their usefulness. A short sketch of 

 the Classes and Sub- Classes of the Vegetable Kingdom has 

 first been given, this is followed by a description of the 

 characters, of the Natural Orders of the Plants of the British 

 Pharmacopoeia, and the Names of the Plants, with their 

 Orders and Officinal Parts, arranged in a tabular form. I 

 have considered it advisable to include the Linnsean Classes 

 and Orders, as they are frequently asked by Examining 

 Boards. Should the object in view be attained, and the 

 labour of the Student lightened, the earnest wishes of the 

 Author will have been amply fulfilled.
