TABLE 250. 



RATIO OF THE ELECTROSTATIC TO THE ELECTROMAGNETIC UNIT OF 

 ELECTRICITY (v) IN RELATION TO THE VELOCITY OF LIGHT. 



* The results in this column correspond to a value of the B. A. ohm = .98664 X io 9 cms. per sec. If we neglect 

 the first four determinations, and also that of Exner and Shida, because of their large deviation from the mean, the 

 remaining determinations give a mean value of 2. 9889 + .0137, a value which practically agrees with the best deter- 

 minations of the velocity of light. (Cf. Table 181.) 

 t Given as between 2.98 X io 10 and 3.00 X io 10 .
