cimens, the result of their discoveries. The name of Dr. Darlington 

 has been long known as the author of a little work under the unas- 

 suming title of ' Florula Cestrica,' or an Essay towards a Catalogue 

 of the Phaenogamous Plants of West Chester (1826) ; containing 

 many valuable and original observations, which have in the present 

 work been greatly extended. Accompanying every species in the 

 • Flora' there is a full description and remarks, an excellent glossary, 

 and a very neat map of the county, coloured so as to indicate the 

 geological structure ; all, in short, that a botanist can wish who is 

 studying the plants of that inland district. The arrangement in the 

 body of the work is the Linnsean, and the author remarks, that 

 ** whilst he freely admits that the true science of vegetables can only 

 be attained by a well- disciplined and philosophical investigation of 

 their structure, functions, and natural affinities, he cannot help think- 

 ing, that even the superficial knowledge of genera and species, which 

 is so readily acquired by the Linnsean system, may be advantageous 

 to the cause, by exciting an early interest in learners, and facilita- 

 ting the first steps of the uninitiated. When the young recruits are 

 once securely enlisted, we may venture to exact a more rigid disci- 

 pline." 



An appendix contains a list of the genera and the number of spe- 

 cies comprised in the work, arranged according to the natural affi- 

 nities ; from which it appears, that there are (exclusive of Cellulares) 

 128 orders, 482 genera, and 1073 species in West Chester County. 

 But of these there are

 We have only recently obtained a copy of this pamphlet, which 

 we consider well worthy of its excellent author ; but although it has 

 been now published for some years, it is scarcely, if at all, known in 

 this country. In it he has followed up the plan which he had adopted 

 in the two editions of his * Novitise ;' taking as his text the ' Flora 

 Suecica' of Wahlenberg, he has written a commentary upon it in- 

 troducing as he proceeded numerous recent discoveries. The first 

 and shorter part of the present publication is chiefly occupied by the 

 description of plants newly added to the Swedish Flora, and the
