324 Mr Conneuu on the Action of 
alcohol are oxidated, and a liquid results which has been called 
the lampic acid, and which, in addition to acetic acid, contains, 
as I also had occasion to show, formic acid, to which its reducing 
properties are owing.* 
Now, in the action of voltaic electricity on absolute alcohol, 
holding zz part of potash in solution, I have stated that hydro- 
gen was evolved at the negative pole, and that a yellow resinous 
matter resulted, and a precipitation of carbonate of potash 
ensued.t These changes appear to be of the same character as 
those which result from the spontaneous absorption of oxygen 
by a strong solution of potash in alcohol, the differences being, 
that in the latter case the oxygen is derived from an external 
source, and the products of the oxidation are, besides the resinous 
matter, acetic and formic acids; while, in the former instance, 
the oxygen comes from the liquid itself, by the decomposition of 
water under the electric agency, and the products of the oxida- 
tion are the resinous matter, carbonic acid, and probably water. 
The latter, in short, is a still more energetic oxidation than the 
former, for carbonic acid is a more highly oxidated body than 
either acetic or formic acids, and if alcohol or ether were oxidat- 
ed to the utmost possible pitch, the products would be carbonic 
acid and water. The oxidating power here is not only the dis- 
posing affinity of the potash, but the presence of nascent oxygen 
arising from decomposing water, and the operation of these causes 
is greatly promoted by the great elevation of temperature attend- 
ing the action. 
Accordingly, I have not been able to ascertain that carbonic 
acid is a product in the other cases of electric agency which I 
have mentioned, where so powerful a disposing affinity is not in 
action as when potash is present. I examined the gas liberated

with contact of air.
