Values of — were obtained from those of E and w by reading 
A w J 
off OP and deducting it from the observed value of E and dividing 
by iv. The following tables contain the results of the determina- 
tion of C. As Kranhals only claims an accuracy in his 
conductivity data of two to three per cent., I have usually 
considered it sufficient to calculate ionizations to two places of 
decimals. In the case, of sodium nitrate the elevations of boiling 
temperature used were the observed values, but for the other salts 
the elevation values were taken from the curves.
