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. 
HE practical exercises and experiments have been so chosen that they 
1 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 combines 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 morphology and physiologyare also fully treated. 
The illustrations number 384, and have been drawn with great care and 
accuracy. The appendix contains valuable suggestions for the teacher, and 
the index is very complete.
