F.R.S., late Secretary to the Admiralty, and author of a 

 very judicious and learned " History of Sumatra," in which,

 ticular study, he has had the naerit of turning the attention 

 of botanists to several valuable plants, among others, to the 

 Camphor- Tree of Sumatra, and to a species of this genus, 

 Marsdenia tindoria, said to afford the best indigo in that 

 island.
