CONDUCTIVITY AND LUMINOSITY OF FI.A.MKS CONTAIN I NT. V.\r<>l;lSI.I> SALTS 1 !. 



k 

 The following table contains some values of the quantities I, & k, t y, and K-, for 



various solutions : 



1L 



It is clear from the above numbers that y varies considerably, according to the 



solution sprayed. Nevertheless, the values for the more dilute solutions do not differ 

 much from '08. 



fr 2 has nearly equal values for the salts of each metal, except for values of I less 

 than about 5 X 10~ 7 ampere. Below this, &, increases as I diminishes, so that I/t, is 

 nearly constant. 



We have thus the following values of k t X 10"' when I is greater than 5 X 10" ; . 

 * The concentration is given in terns of a normal solution.
