The letters (A), (B), and (C) at the heads of the columns of separate values 

 show corresponding sets of readings for Condenser and Resistance-bridge. 



Comparison of Theory and Experiment. 



60. Transmitted and Reflected Systems. — The comparison 

 of theoretical and experimental results for the transmitted 

 and reflected systems of all three condensers is exhibited in 

 Table XI. 



The data for the theoretical values of the ratios are as 

 follows. 



The Reflexion and Transmission Constants for the three 

 condensers are those given in fig. 5 and in the lower part of 

 Table I. . 



The Amplitude Factor, C, for the oscillator is taken as 

 0*716 from the experiments* made in 1898 on the very line 

 now in use. 



The Attenuation Constant, a, was also taken, from the 



* " Attenuation of Electric Waves along a Line of Negligible 

 Leakage," Phil. Mag. Sept. 1898. See in Table II. (p. 301) the value 

 of p, which is the of the present notation.
