Magnetization and Magnetic Change of Length. 573 



(b) Length Change of Nickel- Steels. 



The magnetic change of length of nickel-steel is given in 

 Table IX. and in figs. 4 c, d, e,fg, h, i (PL X.), from which 

 the carves of the change of length for constant fields are 

 obtained and drawn in figs. 5 a, b, c, d, e,f (PI. XI.).
