as eight or nine persons would expire In quietude,
while it would abstract more oxygen from the sur

For out OF door illumination 1t has an additional
advantage that by no possibility can 1t be "blown

not be extinguished In the stormiest weather; and
If the two gases be shut OF for minute or two
the glowing pencil OF magnesa will relight them
when they are again turned on. The preparation OF
this oxygen differs markedly nom the making OF
coal gas; there Is no i'll odor attending it; and If
hydrogen should be employed as proposed by the
same ingenious French chemists, their method OF
iabrcating IL by heating fine anthracite coal dust,
peat or other carbOnace0us substance mingled with
huNr nf lima faryn ntgh for
Illuminating and heating without communicating the
atmosphere Of our crowded cities with the nauseat-
ing and unwholesome gases with which we are now
annoyed.
In point OF economy by the use Of oxygen and
carburetted hydrogen combined with the same
amount Of light the public may save from thirty TO
forty per cent In money allowing large profits to the
or for the same price may have
many times more brilliant, perfect and wholesome
light than Is offered them ut present.
In the Drummond light the piece OF lime usually
employed crumbles in few hours. These pencils or
compressed magnesia last week, and by recent i'm,
provements in Paris crayons have been patented
which have thus far proved TO be indestructbe, as
"they have been employed Tor thirty consecutive
days without any alteration being like new."
This style OF lamp requires duplicate tube-one
for the oxygen and the other for the common illuni
mating or pure hydrogen gas Prior to the employ
OF this most bulky Illuminating agent we can readily
imagine the stout arguments welded TO demonstrate
how dangerous and impracticable TO say nothing
OF the expense, to lay metallic pipes Ior con, con,
in a great city-aye, and In every house and into
every room Of every public private residence II
the advantages to DE secured by this method are as
above warranted, how weak the argument against
an additional pipe for conveying this pure and
wholesome gasl
II has long been favorite belief with many that
the time would come when gases might be com
monty employed for heating as well as Tor illuminat-
ing purposes.
In our chemical laboratories 1t is constantly en-
ployed, and 10 some extent gas stoves and replaces,
nom their great convenience are resorted to- TINS
reduction Of the cost OF procuring heat-yiedng
gases renders the idea less problematcal and con.

processes 10 at least enable to perform all culinary
operations by their aid alone.
AT present almost every Kitchen in our city has
from half bushc to bushel or more of coal burn
ing from morning till night for those purposes, partly
because OF the trouble and expense Of relghtng tho
fires. BY this method the scratching OF match and
turning OF stopcock would be all the labor requisite
to ignite the fires for preparing our meals and neat
ing our dwellings.
For furnaces and factories where the oxygen would
be prepared on the spot learn that 1t can be gene
rated at cost OF from s2 TO So thousand cubic
