TJie same effect was also measured by the ballistic method. 

 The results obtained by these two dilterent methods agreed fairly 

 well with each other, showing that the effect of heating of the 

 coil, if any, must be very small even for nickel, as the follow- 



ing table will show 



TABLE X. 



By the magnetometric method, I also measured the mag- 

 netizations with constant circular fields, the result of which is 

 graphically shown in Fig. 11. 



The hysteresis attending the cyclic changes of transverse 

 field is shown in Fig. 12. The dotted line represents succes- 

 sive steps, till the change becomes at last cyclic. 



Figs. 10, 11 and 12 show that the general feature of the 

 change of magnetization is the same as that for iron. Although 

 there is some difference in quantitative details, the qualitative 

 reöults are generally common to iron and nickel.
