WILLDENOW'S BOTANY. 



THE PRINCIPLES OF BOTANY, AND OF VEGETABLE PHYSIO- 

 LOGY. Translated from the German of D. C. WILLDENOW. A New 

 Edition, with the Author's last Corrections and Improvements. In one 

 large Volume Octavo, illustrated by Eleven Plates. Price 14s. boards. 

 " We have not hitherto had any introductory botanical treatise which 

 comprehends all the branches of botanical knowledge. Lee's Introduction 

 to Botany? which has been longest in use in this country, contains merely 

 an explanation of the system of Linnaeus, and of terms employed by him. 

 Berkenhout's Botanical Lessons is nothing more than an explanation of the 

 Linnaean terms, arranged in alphabetical order. But the author before us, 

 besides explaining the Linnaean method, and the terms used by its followers, 

 likewise gives a very full account of the different natural and artificial sys- 

 tems that have been proposed by different botanists previous and subsequent 

 to that of the Knight of the Polar Star: together with vegetable physiology, 

 explained according to principles established on the latest discoveries in 

 chemistry; the diseases of plants, and the history of botany. In short, his 

 work, which we understand has superseded all other elementary treatises on 

 the Continent, contains almost every thing connected with botany. 



" Upon the whole, however, it is our duty to say, that the same diligence 

 and judgment is displayed in this volume that we already have had occasion 

 to ascribe to M. Willdenow, when pronouncing our opinion of his edition of 

 the Species Plantarum of Linnaeus ; and we venture, without hesitation, to 

 recommend the Principles of Botany and Vegetable Physiology to those who 

 wish to become acquainted with the science, as the most complete intro- 

 ductory treatise on the subject hitherto published."
