The 1834 paper (repr. Experimental Researches in Electricity, 

 Vol. I. pp. 195-258), includes the definitions of electrode, 

 anode, and cathode (p. 196), electrolytes (p. 197), ions, anions, 

 and cations (p. 198), and Faraday's two laws of electrolysis, 

 stated as follows : " That the chemical power of a current of 

 electricity is in direct proportion to the absolute quantity of 

 electricity which passes" (p. 241), and that the "electro- 

 chemical equivalents {of the ions} are the same as their ordinary 

 chemical equivalents?
