DISCUSSION OF RESULTS. 



Table 64 shows the conductivity of the various salts worked with in the pure sol- 

 vents at both and 25. A maximum either at one or both temperatures is fre- 

 quently shown. Other substances show no maximum up to the highest dilutions 

 measured. In several cases maxima occur at one temperature and none at the other. 

 In some cases the maxima occur at the same concentration at both temperatures, in 

 others at different concentrations, but they always occur at concentrations which are 

 close together. The temperature coefficients in general agree very well. Nearly all 

 show a slight increase with increasing dilution. 



Tables 65 and 66 show the conductivity of potassium iodide and cobalt chloride in 

 mixtures of methyl alcohol and water at both and 25. In some cases the maxi- 

 mum conductivities are reached. The maxima generally occur at a greater concen-
