Figure 7. Cadmium. On the left, the heat absorbed by unit quantity of 

 electricit}^ in flowing from uncompressed metal to metal compressed to the 

 pressure indicated on the curves, as a function of temperature. On the right, 

 the excess of Thomson heat in metal compressed to the pressure indicated on 

 the curves over uncompressed metal, as a function of temperature.
