for both results, the fields in which the change is maximum, 

 coinciding in a remarkable way. The amount of the change is 

 generally greater in the present case than in the previous one.

The change of length by magnetization is generally similar 

 to that in pure nickel. But the effect of tension is much smaller 

 and the field in which the effect of an additional tension is null 

 does not differ so much for different tensions as in the former 

 specimen. The results are given in Table IV and in Fig. )>.
