The concentration has been determined by analyzing the most 

 concentrated sobition after the electrolytic method ') with a platinum 

 net for cathode and a platinum spiral for anode. The rest of the solu- 

 tions were obtained from the analyzed by dilution. In order to 

 insure accuracy some have been analyzed. For example the i-esults 

 of two analyses of a sobition, which ought to contain 3,641 "/„ NiCl, 

 according to the way it was prepared, were found to be 3,6437,, ^n<i 

 3,640 7„ NiCl,. 



The following table gives the I'esults obtained ; in the fifth column 



are mentioned the values of X"v, reduced to 20° C. according to 

 Curie's law (comp. § 5).
