TABLE 259. 



THERMOELECTRIC POWER OF METALS AND SOLUTIONS.* 



Thermoelectric power of circuits, the two parts of which are either a metal and a solution of a salt of that metal or 

 two solutions of salts. The concentration of the solution was such that in 1000 parts of the solution there was 

 one half gramme equivalent of the crystallized salt. The circuit is indicated symbolically ; for example, Cu and 

 CuSO 4 indicates that the circuit was partly copper and partly a solution of copper sulphate.
