Bibliography. 147 



It is in some respects peculiar ; its structure is highly methodical ; the 

 subjects are presented in distinct propositions, with definitions, princi- 

 ples, proofs, remarks, inferences, descriptions, illustrations, causes, &c, 

 all drawn out under distinct heads, and distinguished by larger and 

 smaller type. If this construction presents a page more broken up 



than is agreeable to the eye, and less readable as a straight forward 



treatise, it presents important advantages, as a book for classical study 

 and recitation. The pupil will know what to study and how to study, 

 and the instructor what to enquire for. The unsolicited expressions of 

 approbation from many geologists and reviews which are prefixed to 

 trie work, especially the beautiful notice of the distinguished Dr. John 

 "ye Smith, of London, himself the author of an important work on the 

 relation of geology to the Mosaic cosmogony, are to be regarded as 

 Decisive proofs of the approbation of those who are the best qualified 

 to judge. The work bears throughout, the impress of a working, 

 "linking man, of strong powers of observation and reasoning; of one 

 whose impressions are obtained from nature quite as much as from 

 oooks; whose facts are correct, whose views are sound and tenable, 

 and who is therefore a safe guide.

 "ccinct introductory chapter is devoted to the anatomy and structure 

 plants, their chemical composition and products, and the outlines of 

 classification. The officinal plants are introduced under their several 

 Natural orders, which, with the general systematic arrangement of De

 ass of Sporogens is retained, as is still done by the last named author,
