THE THERMAL SPRINGS OF SELANGOR AND MALACCA. 59 



On reference to the data of analysis of the Ulu Klang 

 and Setapak waters, it will be seen that they contain the 

 following amounts of Hydrogen Sulphide dissolved in every 

 10,000 parts of the water : — 



Ulu Klang, ... ... 0.035 (Temp. 151 F.). 



Setapak, 0.034 ( „ 122 F.). 



Now the average amount of Hydrogen Sulphide in cold 

 sulphurous springs may be taken as 0.090 parts in 10,000; 

 hence the Ulu Klang and Setapak contain a very fair 

 fraction of this amount and possess a high temperature at the 

 same time. Both of them may, therefore, be recommended for 

 bathing or drinking purposes. Their action would be stimu- 

 lating and diaphoretic, and they would be found valuable in : — 

 Chronic Skin Diseases and Rheumatism ; Chlorosis ; Amenor- 

 rhea; Secondary Syphilis; Dyspepsia due to disordered action 

 of the liver. I do not think it practicable to bottle and sell 

 the water, as this would result in the loss of almost all its 

 volatile and valuable constituents by evaporation and subse- 

 quent decomposition. The water should be used on the spot 

 and as nearly at the temperature of the spring as may be 

 found endurable. 



The suggestions arising from the above are : — 

 I. — That the hot springs in Selangoi, more particularly 

 those at Ulu Klang and Setapak, are by virtue of their 

 temperature and chemical composition therapeutically valu- 

 able. 



II. — The springs at Ulu Klang and Setapak should be pro- 

 perly set and made available for bathing and drinking purposes. 

 It is almost needless to say that every care should be taken 

 to prevent any communication between the water used for 

 bathing and drinking purposes respectively. 



It should be mentioned here that the Malays and Chinese 

 seem to be well aware of the virtues of these springs, and 

 particularly of their specific action in skin diseases. They 

 bathe in them freely, and I am informed that the Chinese more 

 or less monopolise some springs, the Malays others. As far 

 as I could learn they never drink the water.
