The mother-liquors of the brine-spr 

 gen, and Nauheim were likewise found to contain evident traces 

 of rubidium and caesium compounds, as is seen by the following 

 analyses made in the Heidelberg laboratory : —

The salt which crystallizes from this mother-liquor appears to 



be free from csesium and rubidium ; it is, however, remarkable 



for the large quantity of chloride of strontium which it contains.
