Effect of Stress on Magnetization. 91 



Curves (SI C , H) r , T for cyclic effect shown in the same 

 figures are similar to the above curves, and become coincident 

 with them above a moderate field. The increase of magnet- 

 ization with small twists becomes less as the tension increases ; 

 and for 28*74 per cent. Ni and 70*32 per cent. Ni, it almost 

 vanishes at a high tension.
