Upon the assumption of a strict proportionality the theoretical 

 expectation would be that the initial light at zero time would be 



C 

 half as bright for - as for C. For from equation 2 if / = 0, then 



log / = log Ak. 



k 

 Now if k becomes 2, as a strict proportionaHty would require, / must 



become-' since A is constant. The initial flashes, tabulated in 

 Table III, are seen to be quite erratic, and not at all in line with this
