The elasticity increases by magnetization, the increase 

 tending soon to an asymptotic value as the field increases. 

 The effect o£ tension is to decrease it decidedly. At 

 T = 5003 gr./mm. 2 , the change is reduced to about one-sixth 



of that at r = 890. 



oE 



The calculated values of -=- are generally 



;reater than 



the above values, and the difference becomes smaller, as the 

 tension is increased. With a tension of about 5 kg., this 

 difference almost vanishes. The results' are given in Table 

 XV III. and in fig. 14 with dotted lines.
