314 K. HONDA : ON THE MUTUAL INFLUENCE 



similar to tliat of torsion. Tlio liysloi'esis 1)y llie eyclic change 

 of the longitudinal fiekl, while the transverse held is kept constant, 

 is the same as the ordinary hysteresis, except that the area of 

 the loop is considerably reduced. 



Results in Nickel. 



7) With regard to the eifect of tranverse field on longitudi- 

 nal magnetization and that of longitudinal held on transverse 

 maguetization, nickel behaves qualitatively like iron ; but the 

 effect is generally small. The hysteresis curves have also similar 

 forms as in the case of the former metal. 



In conclusion, I wish to express my thanks to Prof. FT. 

 Nagaoka, under whose direction this investigation was carried out, 

 and also to Prof. A. Tanakadaté for useful suggestions, and to 

 Messrs. D. Sudo and S. Sano for kind advice and assistance 

 in carrying out the present experiments.
