 t = 23.00 X 0.9928 



The curve for Dir in cadmium amalgam cells can now be constructed on 

 the same principles employed in the case of zinc. The two starting points 

 are so nearly identical that no interpolation is necessary. The summary 

 follows. 



Deviations of Cadmium Amalgam Cells. 



54 Interpolated from measurements at 30.00 and at 15.20 by use of absolute temper- 

 ature measurements.
