56 Messrs. K. Honda and T. Terada on the Change of 



(iii.) 70-32 per cent. Nickel-Steel. PL II. figs. 15. 16, 



17. & 18. 

 The change of length by magnetization resembles that for 

 the former allov, though the amount of the change is much 

 smaller. Tension always decreases the elongation, the effect 

 being smaller at greater tensions. Though the tension was 

 increased up to 5b'86 gr./mm. 2 , ^ve could not observe any 

 indication that greater tensions would change the elongation 

 into contraction. The elongation seems to tend gradually to 

 zero with the increase of the load. These results are seen in 

 Table XIX. and figs. 15, 16, and 17.
