368 Prof. Wiedemann on the Magnetism of 



If the glass vessel was filled with solutions of different salts, 

 and, as above, the magnetic momentum produced by the unit of 

 magnetizing force determined, and then the value obtained divided 

 by the weight of the salt in the unit of volume of the solution, 

 the values given in the following Table under m were found.

The values m, the temporary magnetic moments excited in 

 the unit of weight of the salts by the unit of magnetizing force, 

 may be designated as the specific magnetism of the salts. 



The values /jl in the preceding Table are obtained by multi- 

 plying the values m by the atomic weight of the corresponding 

 salt.
