I. Introduction. 



1 HAVE employcd.no inconsiderable portion of the time Application of 

 that has elapsed, since th* last session of the Royal Society, ^^2 p° ur . 

 in pursuing the train of experimental inquiries, on the ap-sued. 

 plication of electricity to chemistry, the commencement 

 and progress of which this learned body has done me 

 the honour to publish in their Transactions. 



In this communication, I shall, as formerly, state the 

 results. I hope they will be found to lead to some views 

 and applications, not unconnected with the object of the 

 Bakerian lecture : and though many of them are far from 

 having attained that precision and distinctness, which I 

 could wish, yet still I flatter myself, that they will afford 

 elucidations of some important and abstruse departments 

 of chemistry, and tend to assist the progress of philoso- 

 phical truth.
