of the Weight of a Body on its state of Electrification. 363 



B. Put 4 volts in and out of one battery of cells. This 

 made no appreciable difference to the deflections. 



C. Zero about 52*5. 



D. Zero taken between reversals. Observations at 1 minute 



intervals. 



E. Put 4 volts in and out of one battery. The only effect was to 

 alter the electrostatic deflection 6 in the ratio 4 : 1000. This 

 alteration was about 0"1 scale divisions. 



4. June l^th. 



A. Zero about 60'5. Electrostatic deflection in opposite 

 direction to last. 



j gave 72'3 



f gave 7 1*3 (about). 



B. Put 8 volts in and out of one battery, no perceptible 

 difference in deflections.
