LEAVITT'S OUTLINES OF BOTANY, $»00 



With Gray's Field, Forest and Garden Flora, . 1 -SO 



With Gray's Manual of Botany, .... 2.25 



For the High School Laboratory and Class Room. 



By ROBERT GREENLEAF LEAVITT, A. M.,. of the Ames 

 Botanical Laboratory. Prepared at the request of the Botan- 

 ical Department of Harvard University. 



THE practical exercises and experiments have been so chosen that they 

 may be performed by schools with even simple apparatus. The in- 

 structions for laboratory study are placed in divisions by themselves, 

 preceding the related chapters of descriptive text. The book combu^es the 

 best features of the newest methods with that lucidity and definiteness which 

 have given Dr. Gray's text-books their extraordinary success. It pays special 

 attention to ecology, but morpholo<,ry and physiology are also fully treated 

 The illustrations number 3S4, and have been drawn with great care and 

 accuracy. The appendix contains valuable suggestions for the teacher, and 

 the index is very comjilete. ^^^^
