of the latter specimen, as it was slightly annealed with a gas 

 flame. 



The change of elasticity calculated from the tension effect on 

 the magnetic change of length somewhat resembles in its aspect 

 that for pure nickel, but the amount of the change is much smaller. 

 The calculated values are given in Table VT and in Fig. 4 

 with dotted lines.

Thus, in pure as well as in commercial nickel, we find a 

 sensible deviation from relation (3).

The change of length due to magnetization is given in Table
