II. The Bakerian Lecture for 1809. On some new Electrochemical 
Researches, on various Objects, particularly the metallic Bodies , 
from the Alkalies, and Earths, and on some Combinations of 
Hydrogene. By Humphry Davy, Esq. Sec.B.S. F.R.S.E. 
M. R. I. A. 
Read November 16, 1809. 
I. Introduction. 
I have employed no inconsiderable portion of the time that 
has elapsed, since the last session of the Royal Society, in 
pursuing the train of experimental enquiries, on the applica- 
tion 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 applica- 
tions, not unconnected with the objects of the Bakerian lec- 
ture : 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 philosophical truth. 
II. Some new Experiments on the Metals from the fixed Alkalies. 
In the paper, in which I first made known potassium and 
sodium to the Royal Society, I ventured to consider these
