THE ELECTROLYSIS OF WATER. 93 
positive electrode. Faraday has shown that this 
occurs sometimes to a considerable extent. In 
the present experiments I ascertained that the 
gases were evolved exactly in the right propor- 
tions, and this because the small quantity of oxy- 
gen dissolved by the solution at the positive elec- 
trode was immediately carried by currents to the 
negative, and there neutralized by hydrogen, as 
the liquid was not divided by a diaphragm. In 
this way however, not more than one sixteenth 
of the mixed gases was re-formed into water. 
Nor can this account in any degree for the deffer- 
ence between the results of columns 7 and 8. For 
in proportion to the quantity of gas re-dissolved, 
is the intensity required for electrolysis undoubt- 
edly diminished. And this, entering the equa- 
tions, has the effect of increasing the calculated 
resistances to conduction, and, in the same pro- 
portion, the results of column 8. We must seek 
another cause. 
And in order to do so with convenience, I 
have enlarged the table. Column 9 contains the 
difference of columns 7 and 8, reduced to an 
equivalent of electrolysis. In other words, the 
differences of the numbers of columns 7 and 8 
would have been equal to those in column 9, had
