weak solutions of potash and soda, and the results were ana- 
logous. With strong solutions of potash and soda a much 
longer time was required for the exhibition of the acid ; but 
even with the most saturated alkaline lixivium, it always 
appeared in a certain period. 
Muriatic acid, from muriate of soda, and nitric acid from 
nitrate of potash, were transmitted through concentrated alka- 
line menstrua, under similar circumstances. 
When distilled water was placed in the negative part of 
the circuit, and a solution of sulphuric, muriatic, or nitric acid, 
in the middle, and any neutral salt with a base of lime, soda, 
potash, ammonia, or magnesia, in the positive part, the alka- 
line matter was transmitted through the acid matter to the 
negative surface, with similar circumstances to those occurring 
during the passage of the acid through the alkaline menstrua ; 
and the less concentrated the solution, the greater seemed to 
be the facility of transmission. 
I tried in this way muriate of lime with sulphuric acid, 
nitrate of potash with muriatic acid, sulphate of soda with 
muriatic acid, and muriate of magnesia with sulphuric acid ; 
I employed the power of 150 ; and in less than 48 hours, I 
gained in all these cases decided results ; and magnesia came 
over like the rest. 
Strontites and barytes passed, like the other alkaline sub- 
stances, readily through muriatic and nitric acids ; and, vice 
versa , these acids passed with facility through aqueous solu- 
tions of barytes and strontites ; but in experiments in which 
it was attempted to pass sulphuric acid through the same men- 
strua, or to pass barytes or strontites through this acid, the 
results were very different.
