IV. With the Glass Ball No. 1. 



Volume of' ball at temperature of liquid oxygen = 6'513 c.c. 

 Density of liquid oxygen = 1*1391. 

 Distance of centre of ball from pole = 4'9b* cm. 

 Magnetic susceptibility of glass ball = 0*48 x 10~ 6 . 



Mean value of susceptibility of liquid oxygen as determined with 

 the glass ball No. 1 = 326 x KT 6 . 



V. With the Glass Sail No. 2. 



Volume of ball at temperature of liquid oxygen = T456 c.c. 

 Magnetic susceptibility of ball = 0'024 x 



Mean value of susceptibility of liquid oxygen as determined with 

 the glass ball No. 2 = 325 x 10 - 6 .
