The only poison in use is ipoh (antiaris toxicaria). Brual, which 

 derives it potency trom an alkaloid allied to or or identical with 

 strychnine, being apparently unknown to them. 



The photograph of an exceptionally large i'poh tree in the jungle 

 near Ijok, which must have been in use for several generations is 

 reproduced on plate xxv. 



During our stay we were able to verify the fact that ipoh is not 

 effective against domestic poultry. A considerable quantity was 

 applied to a Avound on the thigh of an old rooster and though the 

 the bird looked uncomfortable for two or three hours it recovered 

 completely and was later eaten without ill effects by our Malay 

 boys. 



The local Semang, as do other aborigines of the Peninsula, assert 

 that ipoh is without effect on ground game and poultry whereas 

 hrtial has a toxic effect on everything wounded by an arrow charged 

 with it. Ijyoh loses its effect very quickly when kept long and 

 especially when exposed to damp but the poison used on this 

 occasion was quite freshly prepai-ed.
