314 ON THE CALCULATION OF THE CONDUCTIVITY OF 
tions with concentration ranging from 0.1 to the highest 
examined. 1.294, are beyond the limit of error, and are much 
greater than the differences observed for mixtures of Potassium 
and Sodium Sulphate, or for any mixtures yet examined of a 
corresponding concentration. This result would appear there- 
fore to support the view that the double salt does exist as such 
to a certain extent at any rate in solution. 
Comparison of the Conductivity of Solutions of the Double 
Salt with Equivalent Miatures of Solutions. of 
its Constituents.
