half disk of ground glass 3 inches diameter, and was made 

 of a resistance of 23"> ohms, the value calculated to give 

 the same amplitude factor on reflexion as the condenser 

 now in use. This resistance was tested, and if necessary 

 adjusted to 235 ohms, immediately before each time it was 

 used. 



Table X. gives a summary of the results, for both, con- 

 denser and resistance-bridge, of all three sets of readings. 

 From the mean values thus obtained the experimental curves 

 for condenser and resistance-bridge are plotted in fig. 9.
