Here w/Cj (obs.) is deduced from Cx by putting w = 0*46. 

 If the theory were correct we should have 



w /C 1 = 47r 2 (L 1 + L 1 ')/T 2 2 . 



Hence if we plot u\G x against L/ we should get a straight 

 line of which the inclination is T 2 2 /47r 2 , the intercept on the 

 w/Ci axis 47r 2 L 1 /T 2 2 . Such a line is shown by A, fig. 16 ;

all the points except that for L/ =-00075 lie well on it ; the 

 resulting values are L 1 = '00178 henry, T 2 = 0*000172 sec. 

 Both these values are much smaller than those estimated by
