x PREFACE TO THE FIRST, EDITION. 
The last three works will always bear ample testimony to the 
great research and abilities of their respective authors. 
The author has further to express his obligations to his 
spirited publisher, for the numerous woodcuts which he has liber- 
ally allowed him, and to Mr. Bagg for the great skill he has shown 
in their execution. A large number of these woodcuts have 
been taken from Le Maout’s ‘ Atlas élémentaire de Botanique,’ 
several from Jussieu’s ‘ Cours élémentaire de Botanique ;’ others 
have been derived from the works of Schleiden, Mohl, Hof- 
meister, Lindley, Henfrey, Balfour, &c. ; and many are from | 
original sources. By the judicious use of these woodcuts in the 
text of the volume, it is believed that the value of the work as 
a Class-book of Botanical Science has been materially icreased.
