192 LIQUID HYDROGEN SULPHIDE AS AN IONIZING MEDIUM 



In making measurements the cell was filled with a suitable 

 amount of liquid, a weighed amount of the solute was intro- 

 duced, and the solution stirred by cold air passed slowly through 

 the tube A, by means of the pump designed by O. Maass. There 

 was very little evaporation, so that this method of stirring was 

 quite suitable for quantitative measurements. After the sub- 

 stance was introduced, the solution was stirred by two strokes 

 of the pump and the resistance was measured. This was re- 

 peated until a constant resistance was obtained. 



The results are given in the following tables and shown on 

 the curves (Fig. 2).
