149 Morey on the Patent Water-Burner. 
Journal, if thought worth inserting, an account in part of 
those improvements, including a few remarks and experi- 
ments. 
If we put into one of these lamps two parts water, and 
one spirits turpentine, and raise the temperature to about 
204° or 206°, the water boils, and the vapor that comes 
over is composed of about equal Oe of each; or if 
we put in two parts water, two of alcohol, and of one spirits 
pone ae they boil at about 180°, and the vapor comes 
y in that proportion ; or if eight parts of alcohol, 
and sie ofthe oil is putin, they boil at about 160°, and the 
vapor comes over in about that proportion. All these va- 
| i when made to issue through small openings, like gas 
r lights, burn with a pleasant white flame, free from smoke 
orsmell. The water and oil give evidently the most intense- 
ly white flame, but it is somewhat difficult to make them 
burn without a sensible agitation of the flame, and a con- 
_ Stant detonating noise, evidently arising from the perpetual 
decomposition, and recomposition of the water. The ad- 
dition of alcohol adds much to the bulk and mildness of the 
e, but nothing to its intensity. The proportions in 
which these substances will come over, can be made to vary 
by varying the proportions in the lamp, and also by its con* 
struction. It was desirable to have as small a proportion of 
the oil come over, as would give sufficient whiteness to 
the flame. For that purpose, the lamp is generally so con- 
structed as to have the boiling round a tube, or on one side. 
Whenever there is a proportion of water in the lamp, the 
oil floats on the surface, and by the current created at the 
point of boiling, it is carried as far off as it can recede, when 
it will be less agitated, and of course will evaporate the 
slower. In this wa , when I have put in a quart of water, 
and only half a gill of the spirits sed rei the See 
of the former that came over, was nearly two to one of the 
latter, and I thought the arse to $e more tueciely white 
than I had ever observed it before. There is no pretension 
to exactness in these estimates ; by knowing the quantity of 
each that was put in, from the appearance of the residuum 
oe re an estimate was formed of what had been con- 
water and oil only are used, the latter never 
all ¢ comes over. oe appears to be per petually ebanging to a 
_resin, by the decomposition of the water. For common
