* The amount of caesium appears to be very small. On adding chloride of platinum 

 to a rather dilute solution of the alkaline chlorides obtained from this -water, a slight 

 yellow precipitate was deposited ; this, after re-solution and the removal of the platinum 

 by sulphuretted hydrogen, afforded by the spectroscope somewhat faint indications of 

 the presence of caesium. 



t As the state of combination in which the various substances present in mineral 

 waters exist cannot be accurately determined, the system of grouping adopted in the 

 Table must to some extent be regarded as arbitrary. 



\ The difference between the amount of total solid contents found directly and that
