1. Introduction* 



'A HE chemical effects produced hy electricity have been Introductoif 

 for some time objects of philosophical attention ; but the ^^"^' 

 novelty of the phenomena, their want of analogy to known 

 facts, and the apparent discordance of some of the results, 

 have involved the inquiry in much obscurity. 



Art attempt to elucidate the subject will not, I hope, be 

 considered by the Society as unfitted to the design of the 

 Bakerian Lecture. I shall have to detail some minute (and 

 I fear tedious) experiments ; but they were absolutely es- 

 sential to the investigation. I shall likewise, however, be 

 able to offer some illustrations of appearances, which hitherto 

 have not been fully explained, and to point out some new 

 properties of one of the most powerful and general of ma- 

 -terial agents.
