[Marcu 18, 1897 
Instead of placing the two ends of the paraffin in immediate 
contact, four pieces of metal of 1/10 of a mm. thickness were 
placed one at each corner of one of the ends, so that when the 
sticks of paraffin were placed end to end there was now an air 
space of 1/10 of a mm. between the paraffin ends. When B 
was charged and A not charged, and the two put end to end, 
and then exposed to flame or to Rontgen rays, it was found that 
B’s end still retained its charge, and A’s end acquired a very 
slight opposite charge. 
With an air space of 1/5 of a mm. the same results were 
obtained. 
With the air space increased to r mm. the charge on B was 
less after the cwo had been passed through the flame or the rays. 
Similar experiments were made with rods of glass and of 
ebonite, with similar results.
