Electricity will restore it—May not the same or other 
materials, which furnish that electricity, at so very low a 
temperature, furnish it directly to the water, at a higher, 
though convenient one ! 
f water, in considerable quantities is thrown on oil or tar 
if'a state of inflammation, the flame is greatly increased, 
which evidently arises from some effect which the oil has, 
in preparing the water for combustion. 
f oil will, at or near the temperature at which it boils or 
takes fire, produce the same effect, we have only to pass 
the steam of boiling water, through oil at that temperature, 
to furnish a — supply of fuel from the water—and, if 
only the Hydrogen is in the first instance given out for use, 
the Oxygen by mixing or combining with the oil, haeglon me 
doubtedly render it a 
ultimat et assist in making the combustion the more pateiet 
Many experiments seem to justify these’ conclusions, 
some of which will be mentioned. 
If ever so small a drop of water, “rt into oil at a temper- 
ature near boiling, it evidently is decomposed, for pom ex- 
plosive report is sharper than that of gun powder. 
If tar, containing a Pons tee proportion of water, is 
dropped on brick or metal, at a temperature which will 
rapidly evaporate sisi: the vapours burn with white. shoot- 
ing streaks, much flame, and without smoke, while the wa- 
ter lasts. Inflamed drops of tar, burn, while falling, with a 
red flame and much smoke, but on reaching boiling water 
the Sree instuntly disappears, and streaks of a white flame 
te 
in,) to be d erived ‘from the water. 
So aia if steam a led over the ies of tar ina cylin- 
der, and made. to force out a small stream of it, through a 
pipe, into which a quantity of steam is also admitted, and 
made to mix intimately with it, they burn with a great b 
of flame and intense heat, and without smoke provided the 
Proportions are well regulated.
