PENINSULA. 
(Antiaris toxicaria, Lesch.) 
In the Kew Bulletin for February of the present year, pies account 
was given of the investigations which at different periods d ring the 
past 10 years have been carried on through Kew on the pak fo poison of 
the Malay Archipelago. The results are summed up in the following 
paragraph :— 
“ The facts as they stand present a rather curious puzzle. There 
can be no doubt m. in Java the Upas tree furnishes a very effective 
arrow poison be inferred that its use originated in Java and

of the British Resident of Perak to investigate the subject, and I now
