/'. liamlner, Roxburgh, the Oambier Plant, is a native of Penang, 

 Sumatra, Malacca, &c. The substance called Oambier by the Malays 

 is prepared from it, and it is known in commerce by the names of 

 Terra japonica and Catechu. 



This plant was first described by Kumphiuit, ' Herb. Arab.,' v., p. 

 68, t. 34, f. 2 and 3, by the name of l-'an'i uncatm angtuli/oliut, but 

 the process of preparing the extract was first fully described by Dr. 

 C. Campbell, one of the early medical officers of the station of Ben- 

 coolen, who paid considerable attention to the useful plants of tlie 

 neighbourhood. He states that it is chewed by the Malays mingled 

 with betel-leaf and areca nut in the same way that catechu is used on 

 the continent of India, and was solicitous that a trial should be made 

 of its power in tanning. The preparation be describes a* simple : 

 " The young shoot and leaves are shred and bruised in water for some 

 hour*, until a foculum U deposited : this, inpiaated in tho sun to the 

 omtstenoe of a paste, is thrown into mould* of a circulnr form, and 

 in this state tho gambier is brought to market." [CATECUU, in Aim
