For small tensions, the change is an elongation in low 

 fields, attains a maximum in a certain field, passes zero, and 

 afterwards is changed to a contraction. The maximum 

 elongation decreases with the increasing tension, driving the 

 zero towards the weak field ; and beyond a certain tension, 

 the length of the wire steadily contracts with the increase of 

 the field. It seems also that the field corresponding to the 

 maximum elongation slowly moves towards the weaker fields 

 as the tension is increased. These results are in complete 

 agreement with those obtained by former experimenters. 



The change of elasticity for this sample was unexpectedly 

 small, its amount being not very much greater than the 

 limit of experimental error. The values obtained are given 

 in Table VIII. and in fio-. 6 with a full line.
