The observed values of the change of elasticity are as follows. 



Curves are also given in Fig. 14 in full lines.

The elasticity increases by magnetization, the increase tend- 

 ing soon to an a.symptotic value, as the field increases. The effect 

 of tension is to decrease it decidedly. At T=soozgr,lmm,^, the 

 change is reduced to about one-sixth of that at 7^=890. 



The calculated values of -^ are generally greater than the 

 above values, and the differences becomes smaller, as the tension 

 is increased. With a tension of about ö kg., this diflTerence almost 

 vanishes. The results are given in Table XVIII and in Fig. 14 

 with dotted lines.
