THE THERMAL SPRINGS OF SELANGOR 

 AND MALACCA, 



BY 



Dr. W . BOTT, f.c.s., f.g.c.s., &c. 



HE following account represents a brief summary of 

 the results of two official visits to Selangor and 

 Malacca undertaken in August and November, 1890, 

 respectively. Many of the results have already 

 appeared in the report published by Government. 

 A great many details — such as description of appara- 

 tus employed, methods of collecting gases, and analytical 

 methods used, which really form the most valuable part of the 

 paper from a strictly scientific point of view — have been omit- 

 ted, as being obviously not suitable for publication in this 

 Journal ; these will be found in the complete paper which will 

 shortly be published in England and Germany (Proc. Royal 

 Soc. and Berlin Chem. Soc). In reference to the analytical 

 data given, I wish to point out, that these only represent 

 the approximate composition of the water of the springs, owing 

 to unavoidable admixture of ordinary surface water in most 

 cases. I hope at a future date to be able to visit these springs 

 again, provided with such apparatus and appliances as will 

 enable me to collect the water absolutely free from foreign 

 admixtures. The numbers given, however, if not absolutely 

 true, will, I believe, be found to require but a trifling correction 

 in each case.
