 TABLE 327. -Magnetic Susceptibility of Liquids and Oases. 



305 



The following table gives a comparison by Da Bois* of his own and some other determinations of the magnetic sus- 

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



TABLE 328. Values of Ken's Constant t 



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

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

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