The effect o£ applying the 

 from 



maximum tension at once does 

 that obtained by graduated 



not materially differ 

 application of it. 



The change of magnetization by tension under different 

 initial loadings nearly coincides with the above result in the 

 case of 28*74 per cent. Ni ; but in 50*72 per cent. Ni and 

 70*32 per cent. Ni the change is generally greater in the 

 present case than in the former.
