Thermo-electric Action of MetaU in Electrolytes. 203 



variable. The pieces of metal were in each case at 60 and 160 F. 

 respectively. The foregoing Table VI contains the results : The 

 degrees of potential of those cases in which the same metals were used 

 with the weaker liquids are inserted for convenience of comparison. 



Remarks. Several of the remarks made on Table III (p. 2-58), 

 apply to this one. Whilst also there were six cases in which the
