to harmonise in 13 of the cases, but not in the remaining 5. These 

 results also agree with the fact that heat usually increases electric 

 potential of metals in liquids. The influence of increase of tempera- 

 ture on chemico-electromotive force was usually the reverse of that of 

 increased strength of liquid upon thermo-electric potential (see 

 pp. 264, 268). 



The following additional determinations of the chemico-electric 

 potential of two different metals, and with different liquids, all at 

 about 60 F., by the balance method, were made:
