those obtained from the last exixriment, but the difference is that 

 in the former, the positive maxima in weak fields are considerably 

 smaller, the ])oint8 at which ol changes its sign, lie in a lower 

 })art of the field, and dl tends more slowly to zero than in the 

 latter. The effect of tension is to j)usli the point of intersections 

 with the axis of H toward the origin. 



For these alloys, curves {dl, H)-., 7 as deduced from (/, H)-^ j- 

 rather resemble the curves (J 4^ //)t, t obtained from the last ex- 

 periment.
