gion in which they attempt to botanize;* teachers for their own pri- 

 vate use, should be furnished with some work containing; descriptions 

 of all the plants of the country, as Eaton's Manual, Torrey's Bo- 

 tany, &c. Little alteration in the arrangement of the work, has 

 been made in this edition ; a few additions have been made, from 

 suggestions occasioned by the perusal of some English and French 

 botanical works of recent publication $ bnt in none of those works has

 exhibited in this humble volume. 



* Professor Hitchcock's " Catalogue of the Plants growing m the vtcinitij of 

 Amherst College" furnishes nearly all the indigenous plants which may be 

 found in the Northern part of the United States. This Catalogue is the fruit 

 of twelve year's examination of plants, made by the Professor, aided by several 

 eminent botanists.
