This is equivalent to 



0-0599 gram KC1 in 24 hours; 

 and for n LiCl .0*93 cubic centim. per hour, or 

 0-0237 gram LiCl in 24 hours. 

 Another series of experiments gave 



0-0230 gram LiCl in 24 hours. 



The LiCl was not absolutely free from NaCl, although 

 treated a number of times with alcohol in the usual manner. 

 The spectroscope still showed the yellow line. Other metals 

 were absent,

The first of these corresponds to 



0'0476 gram CaCl 2 in 24 hours. 



In another series of experiments with MgCl 2 , 21*6 cubic 

 centims. were required in 16 hours. The average of these 

 corresponds to 



0-0373 gram MgCl 2 in 24 hours.
