of Frozen Electrolytes at very Low Temperatures. 393 



The whole of the observations in the foregoing tables are delineated 

 graphically in the charts in figs. 1, 2, and 3. 



In the case of each dielectric measurement a preliminary resist- 

 ance measurement was generally made to determine the electrical 

 resistance of the frozen electrolyte. It was invariably found that in 

 the case of all the true electrolytic solutions, the electrical resistance 

 of the dielectric at the temperature of liquid air was exceedingly 

 large, generally exceeding many thousands of megohms. 



As the temperature of the dielectric rose the electrical resistance 

 fell down, often very quickly, to a fraction of a megohm, and, long 

 before the melting point of the electrolyte was reached, quite con- 

 siderable conductive power always made its appearance in the frozen 

 electrolytic solution.
