ENERGY CHANGES INVOLVED IN DILUTION OF AMALGAMS. 



When 3-5 was measured Dir was 0.00158 for almost exactly a correspond- 

 ing dilution. This indicates that the oxidation effect in the bottling process 

 is very nearly constant. 



Returning to the question of dilution of amalgam 22 inside the cell, we 

 have:

 Potentials of Zinc Amalgams. Fifth Series; Very Dilute Amalgams. 

 n of 1-volt cell = 0.992B ; t = 23.09 C. 



This was one of the most pleasing measurements in the research ; before 

 the potentials were calculated, the accidental agreement of these two observa- 

 tions occasioned surprise. When the calculations were finished, it was seen 

 that the predicted values also were very close together ; the slight difference 

 between them was of the expected size and in the proper direction.
