TO GAS CONSUMERS.

The idea has gone abroad that the Men,
phis Gsslight company was ready TO
abandon VIVA is termed the nsphths pro-
cess in the manufacture of gas. There
never was g greater tsllsey.
When we consider tho nsterial used
the essential oil OF petroleum, scarcely
m~erchsntGble for any other uss-the RIGA
ness of the gas produced, requiring, when
used as nsphths gas alone, TO be diluted
with forty-two per cent. Of air TO reduoe it
to something like the standard of gss
measured by candle. power) of the fnsst
English camel coal, the rapidity, esK-
tainsy, and, under proper circumstances,
the economy with which it can be pro-
duced, its use must be regarded as an adj
vsnced movement in gas manufacture,
which should receive the attention OF both
practical and scientific msn.
We have found 1t best to uss this pro-
cess in conjunction with the manufacture
of cos gas; First, because we have 8
market tor Ihe resudEl products, cake and
tar, at fair prices. Second, because our
works and apparatus were constructed for
the distillsticn of htuminous Goals,
The late complaints about the quality of
gas supplied 70 the city grew out of the
fact that on account of the stock OF naph-
tina running short, and sons changes be-
ing made 81 the WORKS, the gas in the
holders for q few nights was nearly pure
coal gas, quite equal to the standard for
merry produced by this company. The
change from the use OF naphths was as
percievable and marked as If the burners
had undergone q partial eclipse, and COM
plants IS natural as If one accustomed to
glasses had attempted to lay them aside,
suddenly,
By q slight change made In the connec-
tons with u nspths gas meter, admit
ting only pure naphths gas into the mixer,
we can with ease In set such aqusntity of
this rich, inodorous and disinfeetant gas
into the holders as to Immediately over
come any obi Sctions Is TO the quality of
the gas throughout the city, not only
raising the illuminating power to any
given standard, but absorbing to q great
extent the trace of sulphureEted hydro

the best coal gas.
This we do not claim as a discovery but
the experimental test Of the use of pure
naphtha was most interesting and salts

On the evening of the 2Osh, about four
O'Clock, we had succeeded in getting ready
for trying She effsct on a large scale, of
what is known in chemistry as gaseous
diffusion, without regard to specific grav-
ity. Not b uniform interminRling of

tended) twenty-eight miles in length.
The holders contained about 10000 feet
of gas, with q make of about nfteen to
eighteen thousand feet per hour, when we
commenced turning in the pure nsphtha
gas Earning only two benches OF Zsl
and making at the rate of shout eight
thousand cubic feet per hour. The pho
tometer (Sugg's make, London,) meas
ured the coal gas then in the mains at
fourteen csndle-poWer.
As soon as we observed from thu test
Lights the naphtha gas was filling the
pipes, we noted b o~andls-power Of the
in The street mains to begin rapidlv |
and steadily to ascend, and in twenty
minutes more, we found 1t was eighteen
ca~ndle-power.
Going immediately to the office, In the !
heart OF the city, to note the effect there, |
we found every n inquiring what hsd
and surprised at the increased
brillisncy Of the light.
Thus in twenty minutes the Tlumin- |
atiug standard OF coal gas fourteen can |
die power, was raised to eighteen.
By nc other process known to modern
and practice can suck results be
produced 30 rapidly. In the ordinary
manufacture of coal gas, complaints as to
quality can only be remsdied by a gradu-
al process, which generally m too late
to meet complaints.
BY this method alone Is the effect inme-
diste.
We can, therefore, assure the public that
hereafter any just complaints as to the
illuminating quality Of the gas furnished
CITY, can and shall be remedieo
promptly not in one locality only, but
the extent of our mains. It
must bs understood, however, we cannot
and do not undertake to make gas doW
through pipes filed with scale or rust.
