CONDUCTIVITY AND LUMINOSITY OF FLAMES CONTAINING VAIiUMSKD SALTS. I I, 



The agreement of the calculated and observed values in the above tables shows 

 that the relation between the current and E.M.F. in our experiments can be repre- 

 sented with considerable accuracy by the formula in question. 



In order to show that t gradually attains a maximum value in our experiments as 

 the E.M.F. is increased, the calculated values oft are inserted in a separate column of 

 the foregoing tables. 



In the case of yj^ normal KC1, y^j normal K 2 CO,, t\> normal KjSO 4 , and NaCl, 

 it will be seen that i has almost reached its maximum value, that is, it has become 

 nearly equal to I at an E.M.F. of 5 volts. 



In the case of \ KBr, this is the case at 6 volts, whilst in the case of KOH the 

 maximum value is not quite reached at 6 volts. 



The values of i are plotted in Curves X and XI. As was to be expected, the fnrm 

 of these curves is perfectly similar to those given by THOMSON and RUTHERFORD.
