ON THE SO-CALLED TIGER'S MILK 
“SUSU RIMAU” OF THE MALAYS. 
BY 
HEN: RIDEEY, M:A.,. F.L-S. 
While staying recently at Pekan ! procured, through the 
kindness of Mr. RODGER, a fine specimen of the remark- 
able vegetable production, known to the Malays here as 
‘Susu Rimau.” The tradition is that it is the congealed milk 
of the tiger, and it is stated to produce eventually a climb- 
ing plant. It is considered a valuable medicine for asthma 
and other chest complaints, and is sold in the bazaars ata 
high price. The specimen given me by Mr. RODGER was 
considered a very large one, being about four inches cube, 
but a later one was brought in from the forests at Bukit Man- 
dai in Singapore which is even larger, being six inches in 
length and three inches through in the thickest part. Profes- 
sor VAUGHAN STEPHENS gave me alsoasmaller specimen from 
the interior of Pahang. 
The structure and appearance of all seem very much the 
same. Each consists of an irregular white mass lobed and 
cracked all over, covered with a thin rind, terra-cotta red in 
the fresh specimen, browner when older. When fresh the inte- 
rior is of the consistency of cheese, white, scentless, and with 
a faint funguslike taste. When dryer, and in old specimens 
it becames chalky and vimer. 
Under the microscope a section shows it to be a very com- 
pact mass of fungus threads (mycelium) with which are mix- 
ed innumerable globose cells. In the fresh specimen from 
Bukit Mandai the mycelium is very scanty, and in all it is 
very much less in quantity than the white globose cells.
