GEAY'S LESSORS lU Bo'rAUY, 



REVISED. 

 OR, THE ELEMENTS OF BOTANY FOR BEGINNERS AND SCHOOLS. 



Designed to take the jjlace of a former work of the same title, and adapted to higher grades than the " How Plants Grow." 



WHILE in some respects more extended than the work it is made to replace, it is also more concise and terse. It is intended to ground stu- 

 dents in Sliuciural Botany and the principles of vegetable growth, mainly as concerning flowering plants, as well as to be a companion and 

 interpreter to the Manuals and Floras. While like a grammar of any language this work abounds in technical terms, they are so introduced and 

 elucidated that they invari.Tbly convey knowledge and ideas. 



It is believed that the illustrations in this volume, which number nearly 600. will b- found specially helpful and instructive. 



Extra cloth, 226 pages, 589 illustrations. Price for Introduction, 94 cents. 



. . . I have no hesitation in saymg that no other elem-ntarv botanical work ever issued is to be compared with this 

 "Gray's Lessons, Revised." Yours very truly, 



DANIEL C, EATON, Professor of Botany.
