FIRST BOOK OF INDIAN BOTANY. With numerous 

 Illustrations. Extra fcap. 8vo. 6s. 6d. 



This manual is, in substance, the author's " Lessons in Elementary 

 Botany," adapted for use in India. In preparing it he has had in 

 view the want, often felt, of some handy resume of Indian Botany, 

 which might be serviceable not only to residents of India, but also to 

 any one about to proceed thither, desirous of getting some pre- 

 liminary idea of the botany of the country. It contains a well- 

 digested summary of all essential knowledge pertaining to Indian 

 Botany, wrought out in accordance with the best principles of 

 scientific arrangement." Allen's Indian Mail.
