Observed position of equilibrium. 



Deviation. 



The observation of the difFerence of potential at the ends of the 

 resistance of .500 ohm has been repeated a few times for one of 

 the two directions to find out, whether the intensity of the current 

 has changed during the experiment; it appears that it has remained 

 perfectly constant. 



The results of this experiment have been collected in table III ; 

 the two numbers between brackets represent the deviations caused 

 by the current in its two different directions.
