1) These solutions were prepared by dilution, and mixture of an aqueous NiSOj,- 

 solulion, for which two analyses gave 16,587 and 16,592'Vo NiSO^ and a solution of 

 ammonia in water, for which two analyses gave 11,53 and 11,49% NH^. Tlie 

 ammonia analyses were performed by titration witli '/s normal chloric acid. 



^) These solutions were prepared by dilution and mixture of an aqueous NiCL- 

 solution for which two analyses gave 17.216 and 17.190% NiGl2 and a solution 

 of animona in water for which two analyses gave 11.782 and 11.783% NH3. 



■') These solutions were prepared by dilution and mixture of an aqueous so'ution 

 ol NitN08)2, for which two analyses gave 19.539 and 19.514 »/q Ni(N0s).2 and the 

 same NHg-sotution in water as with tlie ammoniacal NiClz-solutions.
