418 Herbarium of the Calcutta Botanic Garden* [No. 5* 



I might illustrate each of these floras at great length, but the 

 object of this paper is not to bring forward examples of each, but 

 to induce botanists to lend their assistance in establishing their 

 limits on a sure basis of observation, by collecting as far as they can, 

 and transmitting for examination and comparison, the plants of their 

 respective neighbourhoods, so that the exact area inhabited by 

 every species may be ascertained, and the main facts of the Geogra- 

 phical Botany of India be accurately determined.
