S AN ESSAY ON THÉ OOFAS^ OR 



to the violen ce of these efifects the JPoison is 

 supposed to be active. 



A Dissertation bas been published by Chrisp : 

 Aejmlaeus at Upsal, which contains the sub- 

 stance of the aceoimt of Rumphuis ; an extract 

 from it is given in Dr. Duncan's Medic : Co- 

 ment : for the year 1790, 2d vol. Vth. Decad. 



It appears from the account of Rumphuis 

 that this tree is also found on Borneo^ Sumatrs 

 and Bali. 



Besides the true Polson Tree^ the Oopas of the 

 Eastern Islands and the Antshar of the Javanese, 

 this Island produces a shrub, which, as far as 

 observalions have hitherto been made, is peculiar 

 to the same, and by a dififereut mode of prepara- 

 tion, furnishes a Poison far exceeding the Oopas 

 inviolence — lts name is Tshettik, and its speciüc 

 description will succeed to that of the 

 Antshar — The genus hasnot y et been diseovered 

 ordescribed. 



Description of the Antshar

 of LinnaeuS;,the Monoecia — The male and female 

 flowers are produced in catkins ( Amenta) on the 

 same branch, at no great distance from each
