Uncaria. pentandria monogynia. 519 



" The price at which it can be procured from the Northern 

 parts on this coast, I have ascertained to be nearly ten dollars 

 per hundred weight, it can be supplied in any quantity de- 

 sired, for the plant abounds in these districts, and the mode 

 of eliciting the astringent matter is such as requires neither

So far Dr. Campbell. But in other parts to the eastward 

 of the Bay of Bengal I learn that the process is carried on by 

 boiling the leaves and young shoots ; evaporating the decoc-

 spissated, it is spread out thin and cut into little square cakes 

 and dried. 



The same substance is mentioned by Marsden in his Histo-

 of the cultivation of the plant and manufacture of the Gam- 

 bier, to the 2d volume of the Transactions of the Batavian 

 Society.
