CLXXXV.—IPOH POISON OF THE MALAY PENINSULA. 
Antiaris toxicaria, Lesch. 
The use in the Malayan region of a Masa poison to tip the 
bamboo arrows, which are discharged from a blo w-pipe 7 is too well 
known to need description. To this the name Upas is given in Java, 
and Гро by the Malays elsewhere. Both ra have the same meaning, 
and, according to Blume, эмн а. signify poiso 
dh 
to cds the sap when drawn off mem анг Ld elaborsió pre- 
paration before the blow-pipe arrows are tipped with it. But he 
expresses the probable opinion that the sap alone would be found 
equally deadly. 
ts poisonous properties are, in fact, due to a definite chemical sub- 
stance which has been extracted from it called Antiarin. this the 
following short account may be conveniently extracted from Watts’ 
Dictionary of Chemistry :— 
* Antiarin. (CHO +20.) The poisonous principle of the 
Upas Antiar, a kind of n resin which exudes from the Upas tree 
йн toxicaria), and is абе by the Javanese for poisoning
