 TABLE 327.— Magnetic Susceptibility of Liquids and Oases. 



305 



The following table gives a comparison by Du Bois • of his own and some other determinations of the magnetic sua. 

 ceptibility of a few standard substances. Verdet's and Kundt's constants are in radians for the sodium line D. 



TABLE 328.— Valaes ol Kerr's Oonstantt 



Du Bois has shown that the rotation of the major axis of vibration of radiations normally reflected from a ma^et is 

 algebraically equal to the normal component of magnetization multiplied into a constant JC. He calls this con- 

 stant, K, Kerr's constant for the magnetized substance forming the magnet.
