In regard to these two experiments, the Semangs said that neither 
fowls nor argus pheasants are affected by the poison, and that as many 
as ten darts may be stuck into one of these aded without causing its 
death. It therefore became necessary to try an ex ресто. оп а

шу presence the day before, the virulence of the Malayan Antiaris 
pres ini is proved beyond the shadow of a doubt. The poison seems to 
be as rapid as the Javan Upas, 19 minutes only having elapsed between 
inoculation and death, while the animal was quite disabled in 10 minutes 
time. 
These experiments also prove the comparative immunity from the 
effects of the Ipoh poison enjoyed by fowls, which is a matter of con- 
siderable scientific interest. 
The previous experiments which have been made on samples of Ipch 
sent from the Malayan Peninsula, as detailed in the February number 
of the Kew Bulletin, can only be explained in two ways ; either the sap 
menters in England. 
There is no doubt that the material collected in 1881 by Sir seme 
Low, the then Resident of Perak, was quite authentie, as its poiso 
properties were tried on some dogs here before it was transmitted to Tap $. 
but the information and material supplied to a D. Hervey was evi- 
dently not reliable, for the ар of Antiaris is poisonous per se аз every 
aborigi al knows, and there is no such vie s as “ нн of [рой aker,” in 
-detail. This extract, had it been sent, would have been very unlikely to 
ecompose, as the Sakais diee it for years and say it does not lose its 
virulence 
What Griffith says about the poisonous properties of the Ipoh being 
derived from admixture of arsenie, was information probably derived 
from the Malays, for the aborigines are quite ignorant of that c 
and as Professor Ringer points out, the action of arsenic is very differen
