Preliminary. 

 661. f T , HE theory which I believe to be a true expression 

 -■- of the facts of electro-chemical decomposition, and 

 which I have therefore detailed in a former series of these 

 Researches f, is so much at variance with those previously ad- 

 vanced, that I find the greatest difficulty in stating results, as 

 I think, correctly, whilst limited to the use of terms which 

 are current with a certain accepted meaning. Of this kind is
