In general features, the change of rigidity is similar for 

 the three specimens. Magnetization generally increases the 

 rigidity : the change increases rapidly with the field and 

 soon tends to asymptotic values. The effect of tension is 

 invariably to diminish the change of rigidity. The last two 

 specimens, which in weak fields display a slight decrease of 

 rigidity, resemble each other not only in their general 

 behaviour, but also in the amount of* their change. In 

 28*74 per cent. Ni, the amount of the change is much less 

 than that for the others. It is to be noticed that the general 

 aspect of the change of rigidity resembles that of the change 

 of elasticitv.
