CHAPTER VI. 



THE BEHAVIOR OF THE IONIZED PHOSPHORUS EMANATION AS THE DIELECTRIC IN 



SPHERICAL CONDENSERS. 



1. — lu the preceding chapters it was assumed that the conditions could be so 

 chosen (swift air currents, highly active ionizer, etc.), that the decay of the ioniza- 

 tion might be temporarily disregarded. Such an assumption is naturally precarious,

and the following series of experiments are planned with particular reference to the 

 factor ignored. Accordingly a closed spherical conden.ser was installed, with its 

 outer surface put to earth and its inner (concentric) surface, always very small, in
