Badulla, 16th April, 1853. 



Sir, 



It affords me great satisfaction indeed, to find from your letter of the 

 1 2th March last, that my efforts to draw public attention to the Vegetable 

 products of my native country, have met with so much encouragement 

 at the hands of your Society, Allow me now to offer them my best 

 acknowledgments for the notice they have been pleased to take of my 

 labours in the field of Botany, and to assure them, that this will prove 

 no small stimulus to me to continue to devote myself to my favorite study. 



As the mode of preparing the Vegetable Products which I have pre- 

 sented to the Society, and their uses are described in the accompanying 

 little pamphlet, I take this opportunity of requesting the Society's kind 

 acceptance of the same. 



I remain, &c, 



W. C. Ondaatj.e s
