126 ON THE CALCULATION OF THE CONDUCTIVITY OF 



These values were plotted on co-ordinate paper with con- 

 centrations as ordinates and conductivities as abscissge, and 

 smooth curves were drawn between the points so as to obviate 

 accidental errors. Conductivities were taken off these curves 

 and compared with the numbers given by Kohlrausch* for 

 solutions of equal concentration, as shewn in the following table, 



POTASSIUM CHLORIDE. 



SODIUM CHLORIDE.
