12. New Method of Illuminating Houses with Gas, 
The great improvements which have taken place, both in the 
manufacture of gas, and in the methods of applying it for the 
purposes of illumination, render it extremely probable that it 
will be much more extensively employed in lighting up private 
houses. Many persons have an objection, which we confess is 
not without some foundatiop, to introduce the gas directly into 
their apartments ; and it has accordingly been proposed to bring 
the gas to the windows, to allow it to burn on the outside, and 
thus to illuminate the room, without any of the amioyances 
which arise, both from the smell of the gas, and from the heat 
generated during its combustion, 
In order to do this to the greatest advantage, the gas-pipe 
should be brought to the sill of the window, and should then 
have a gas-tight joint, by means of which it can be placed ei- 
ther vertically, when it is to be used, or horizontally, when 
the apparatus is to be removed altogether, pr put aside during 
the day in a press or recess made in the wall to receive it. 
The lamp which is to protect the gas from wind and rain, 
should have fronts of glass either hemispherical or semicylindri- 
cal, so that no opaque line or bar may interfere with or 
break the cone of rays which enters the window. The back 
part of the lamp must be a reflector, of such a surface that it 
shall throw into the apartment all the rays that would otherwise 
not enter. The direct and reflected light which thus enter the 
apartment, might be rendered uniform, by means of an orna- 
mental blind of the flnest muslin, (varnished or not as may be 
found most advantageous) ; and if the blind has a landscape 
upon it, the most luminous portion, or that nearest the gas 
flame, might be made to have the appearance of the sun in the 
heavens. 
Jn newly built houses, recesses might be constructed, in such, 
a way that the lamp and gas-tube might turn round a joint, and 
be entirely concealed from view in the day-time. 
The advantages of such a method of illumination are great 
and obvious. Instead of being annoyed by the constant en-
