Applying the first formula given in Table II. the 

 values from 65 to I2'5 volts have been calculated. 



It is important to get direct verification of this 

 polarisation by cutting the supply voltage out of circuit 

 and immediately connecting the electrodes to a galvano- 

 meter. 



This was done by charging the body for one minute 

 and then immediately discharging into a galvanometer. 

 After a small interval of time (necessary to read the
