data obtained in the present work. With few exceptions all the points 

 lie on one curve, and the slight deviations which occur are within the 

 limits of error of the conductance method. The four other salts give 

 similar results; therefore their graphs are omitted.

It has been found impossible to obtain, experimentally, a value for 

 the limiting conductance, although measurements have been carried 

 out to 10,000 and 20,000 liter dilutions. It is therefore necessary 

 to determine A by some method of extrapolation. It will be recalled 

 that Goldschmidt used the Kohlrausch formula for this purpose (see 

 page 101), although its applicability to alcoholic solutions and even 

 to aqueous solutions 1 had been previously questioned. We applied 

 this formula to our experimental data with a similarly unsatisfactory 

 result. The calculated values of A vary to such an extent that it is 

 impossible to make a selection. 



A function of another form, suggested by A. A. Noyes, 2 which has 

 been successfully used in connection with researches upon the electrical
