Tliii.s the general diameter of the change of depression is 

 similar to that of soft iron ; but the initial decrease is not observed. 

 The course of the curve is much steeper than in soft iron and wolfram 

 steel, and less asymptotic to the axis of the magnetizing fjrce.

Thus the increase of elasticity under a corjstant üeld reaches a 

 maximum with a load of between 11270 and 2200 "rams. On both 

 sides of the load, it gradually decreases as the load is increased or 

 decreased. These results approximately agree with those of wolfram 

 steel obtained by the method of elongation.
