Table II.— Co-efficients for Schaefer's Test. 



The milammeter 50 range was used, and therefore the 

 reading 40 must be divided by 3 to bring to mllliamperes. It 

 must further be divided by 2 to get milliamperes to line, as 

 the milammeter was in the battery circuit. Hence — 



nc= = 6-66 m/amps. 



e = 1,090 m/volts, 

 and the correction,
