hardens after about 10 days. Practically all of the 
supply of dragons' blood is sent to Singapore, from 
which place it is exported. It has a value of from 
$20 to $40 per pikul and the total amount exported 
is not great, amounting to only a few pikuls per 
year. It has now disappeared from all pharmacopeias 
and is used principally for Chinese medicine. Small 
quantities are used in factories of spirit-lacquer, but 
it seems to fade in the light. Painters sometimes 
prepare it with gum water to make a pung$e paint 
like Florentine lacquer, but it cannot be mixed with 
oil. It is sometimes used to produce a red colour 
in woven rattan. Dragons’ blood gives a pleasant 
odour when thrown on coals and is therefore some- 
times used as an ingredient of incense. It will 
probably always be found in sufficient quantity to^ 
supply the limited demand which exists for it. 
The species, occurring in the Malay Peninsula, 
which are credited with producing dragons' blood 
are the following: — 
Daem,onorops propmquus Becc., known as Rotan 
Jerenang, 
D. micracanthus Bicc., known as Rotan Jere-

D. didymophyllus Becc., known as Rotan Getah, 
Rotan Hudang, and Rotan Butong. 
IV. — TRADE IN RATTAN. 
Rattan is the most important of the minor pro- 
ducts of the forest in British Malaya. It has a very 
large local and domestic use, the value of which is 
very hard to estimate. The material collected for
