equalled, and which has already been appreciated and gratefully acknowledged, not only in this country, hut 

 throughout Europe, immediately directed me to proceed to the distribution of the duplicates among the principal 

 public and private museums in Europe and America. They were pleased to order a similar distribution of the 

 herbariums of continental Indian plants in their Museum, made by Drs. Patrick Russell, Roxburgh, and Hamilton, the 

 Tranquebar Missionaries, the late Mr. Finlayson, Mr. Wight, and myself. T\m assistance which I have already received 

 in the laborious details connected with the above distributions, has placed me under the greatest obligations to some 

 of the most eminent botanists of Europe. I have been honoured by the personal aid of Mr. Brown, Professors 

 Kunth, Hooker, "Graham, and Lindley, M. Alphonse DeCandoUe, Mr. Arnott, Mr. Prescott, and Mr. Bentham. 



Besides the homage which has been paid to the Company in many publications for their princely liberality in thus 

 affording these ample means for the diffusion of a knowledge of the botany of the East Indies, a still more 

 effectual method of testifying a sense of the general obligation they have conferred upon the scientific world, has 

 been adopted by a number of celebrated Botanists, who have undertaken to publish Monographs of the moro 

 extensive and interesting families, thereby powerfully contributing to the completion of a scheme so truly worthy of 

 the British East India Company. 



It is a source of pride for me to introduce here the names and separate labours of those who have thus zealously 

 come forward to advance the interests of science.
