Starting condition wet N2 



tractiiig from (8A c.p./5) a Dember potential correction, given by 

 {b — 1)/(X + b\'^). (The boundaries of the illuminated region were 

 sufficiently distant from the contacts for this formula to apply.) 



Tables III and IV include only data from the second half of the 

 cycle (wet N2 -^ ozone), since the rate of change of A c.p. during that 

 part of the first half in which dry oxygen was replaced by wet oxygen 

 was too fast to follow.
