CHANGE OF ELASTIC CONSTANTS OF FERRO:\rAf;XETICS. 



•>) 



table. The change is ooniinoii tor all these specimens ; the rigidity 

 first decreases, attains a minimum, and tlien gradually recovers 

 its initial value, as the lield is increased. In still higher fields, 

 a slight increase is observed, which increases with the field. 



The fact that the change of rigidity becomes appreciable, 

 only when the S2:>ecimens are once dipped in liquid air, is to be 

 expected from its magnetic property as regards the cooling in 

 liquid air."''
