Thei^mo-electric Action of Metals in Electrolytes. 275 



Table XIII. (continued). 



* Indicates a temporary reversal with the two contiguous metals, i.e., the one 

 marked and the one above it. 



Remarks. The usual strength of the current obtained in this series 

 of experiments was but little greater than those obtained with the 

 weaker liquids at the same temperature. Silver was nearly always 

 the most volta- electro-negative metal in alkaline liquids, except in 

 potassic cyanide, whether they were strong or weak (see Tables X and 

 XIII). Copper was remarkably volta-positive, both in hot and cold 

 weak solution of potassic cyanide (see Table X), and in a strong 

 cold one.
