when first placed under pressure is increased more than the value given 

 above. The pressure caused an increase of the temperature of the oil and 

 a decrease of the temperature of the electrolyte in the neighborhood of the 

 crystals. This has been shown by means of a thermo-junction. The exact 

 results will be reserved for further investigation. 



Both these temperature changes affect the E. M. F. of the cell. After 

 a time, a half hour say, the cell reaches a constant E. M. F. When the 

 cell was first placed under a pressure of 1,000 the E. M. F. was changed 



78x10"^ volts. The final change after thirty minutes was 6.4~''xl0'^ volts
