PREFACE 



In publishing the present work I have to acknowledge my 

 indebtedness to Mr. W. Miller for the many names I have 

 culled from his " Dictionary of the English Names of Plants " ; 

 also to the curators of the Natural History Museum, and the 

 Botanical Gardens at Kew, Penang, and Colombo, for their 

 courtesy in affording me opportunities for study. 



I have been criticised, regarding a former work, for not 

 naming the toxins of many of the plants. When these 

 principles have been identified, and possibly a revised classifi- 

 cation made by the Botanists, I shall be in a position to make 

 amends in a future edition. 



The plants illustrated, and whose numbers correspond to 



their descriptions in the text, are reduced one-fifth. The 



Micro-Fungi and Bacteria are magnified five hundred 



diameters.
