Electricity will restore it—May not the same or other 
materials, which furnish that electricity, at so very lowa 
temperature, furnish it directly to the water, at a higher, 
“though convenient one ? 
If water, in considerable quantities is thrown on oil or tar 
in a state of inflammation, the fiame is greatly increased, 
which evidently arises from some effect which the oil has, 
in preparing the water for combustion. 
If 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 regular 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, will un- 
doubtedly render it a drying oil, and more combustible, and 
ultimately assist in making the combustion the more perfect. 
Many experiments seem to justify these conclusions, 
some of which will be mentioned. 
If ever so small a drop of water, fall into oil at a temper- 
ature near boiling, it evidently is decomposed, for the ex- 
plosive report is sharper than that of gun powder. 
If tar, containing a considerable proportion of water, is 
dropped on brick or metal; at a temperature which will 
rapidly evaporate them, the vapours burn with white shoot- 
ing streaks, much flame, and without smoke, while the wa- 
ter lasts. Infiamed drops of tar, burn, while falling, with a 
red flame and much smoke, but on reaching boiling water 
the smoke instantly disappears, and streaks of a white flame 
shoot up. 
If water m one cylinder be made to boil, and the steam 
be led to the bottom of another, containing rosin or tar, at a 
high temperature ; after passing up through it, the water to- 
gether with the vaporized portion of the rosin or tar, will, 
when the proportions are properly regulated, burn with an 
intense white flame and no smoke, much the greater part of 
which, appears (by alternately shutting the steam out, or 
letting it m,) to be derived from the water: 
So also if steam be led over ihe surface 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 naenitbeds “andy 
made to mix intimately with it, they burn with a great body 
of flame and intense heat, and without smoke provided the 
- proportions are well regulated.
