Here again it will be seen the charging action was a positive one 

 in both cases, and when the needle was positively charged its motion was 

 somewhat more rapid than when it was negatively charged. In both of 

 these two latter sets of observations the volta effect produced a deflection 

 in the negative direction when the earth connection to the free quadrants

was broken at atmospheric pressure; but in each case after these earth 

 connections were broken the complete apparatus was left undisturbed 

 for some 8 hours in order that the needle might take up its stationary 

 position corresponding to the volta effect displacement. From time to 

 time during this period observations on the scale readings were made»
