]. N. Green then took the floor and made
an address Mandatory Of Collector Boswell,
whom, he said, must not be classed with
the othsr officials at the City Hall. Mr..
Boswell was q good and true man who de-
served the thanks OF every rlght-mlnded
man for the hrm positions he had taken
when II was necessary 10 maintain the right.
Chaplain Green was interrupted frequently
by Isley Walton, colored man, who was
evidently In favor OF Mr.. Bowen. Mr..
Green answered him good-humoredly, finally
giving way TO allow Walton TO deliver a
haranguo In favor OF the present municipal
administration. When he ceased, the meet
Ing adjourned, having been characterised
with the best order, and the proceedings
conducted In q dellberatlve and impressive
manner.

aArkablo Success with . New Ia
VsntIon.
For slI months past there has been much
quiet attention bestowed hero upon q new
and very remarkable Invention, which has
been In process OF development under the
management Of two energetic gentlemen,
who, nearly q year ago, 1rst hled their APP
plieation for patent Tor q new process for
converting petroleum to the usos OF fuel.
This subject had so long engaged the atten-
tlon Of many practical and scientific men,
and success had so often Just escaped their
grasp, that In many quarters the achieve
mont OF Anal success had been abandoned.
But the Inventors Of the new process being
practical men, and having at their command
many meritoriouS Inventions lAngulah and
die, have pushed their achievement quietly
but steadily, until II ID bringing To this city
from distant parts Of the country, hundreds
Of practical men interested In the great Ques-
ton Of cheap fuel, who desire TO determine
from personal observation, what degree Of
merit can be attached 10 this new discovery.
1t Ia to DO said, to the credit Of the invent
ors, that they have not not sought TO attract
public attention BY any hlgh-soundlng bull
letlns and extrayagant promises, they having
In seven months Of experiment permitted
but one public announcement. This has
been, In order to place themselves and their
invention on such basis that when they
were ready TO challenge public scrutiny, the
result might be assured. A great many prl-
yRte exhibitions have been given, which
hayo been Witnessed by many gentlemen,
prominent In engineering and professional
circles. Among them may be mentioned
W. Prescott Smith, esq, OF railroad fame
Edgar l.. Thomson, Of the Pennsylvania
Central railroad 7. L. Rowland, ESQ.,, of

Captain Ward, Of the Royal British navy
Captain Breese, United States navy Hon.
oakes Anes, Of the Union Pacldc railroad
Colonel W. X. Roberts, Of Philadelphia, and
others Of similar standing.
Yesterday an exhibition was given before
q company Of twenty-five or thirty profess
slonal gentlemen, engineers and Journalists,
among whom were Hon. Cakes Ames, Gen.
Denver, Hon. l.. II. Chandler, Of Virginia
A. B. Mullett, esq, Supervising Architect OF
the Treasury Department. Captain Breese,
United States navy James r. Young, esq,
OF the Iribunsj II. J, RRmSdell, OF the Gin
cinnAti Commercial; d. r. Mckee, Of the
San Francisco Bullstin Professor Hedrlck,
OF the Patent Office, and others. The en-
Periments occurred at the foundry Of W. A.
DuVall q Co., OF Georgetown.
The process Is In brief ~ follows Steam
is taken from boiler aud passed by plpc
Into tina hra-hnr. uhAra IA forced through
small iron-cyllndor, known as the super
heater, which increases the temperature Of
the steam TO from 500 TO / 200 degrees, az
may be required. Thence Ii passes through
a pipe Into cylindrical tubular generator,
the petroleum being contained In the space
around the tubes, and by lts heat rapidly
generates the oil Into gaseous vapor, The
capacity Of the cylinder now In use is eighty
gallons OF crude petroleum. The gas, a.
fast as generated, passes into receiver,
which encloses the generator like q water
Jacket thence by pipes into the fire boz Of
the boiler, whore Il u introduced by Jets OF
burners In such volume as to produce q
name which dlffuses itself the full length OF
q thlrty-nys feet boiler, and several feet Into
the smokestack, with the apparatus only
working at one fourth Its capacity, At the
same time the steam returning from the
generator at au innammable temperature is
mixed with the Vapor, improving the com
bustion, increasing the heat and lesseuinR
the consumption.
For the past two months the daily duty
OF the apparatus has been 10 drive q thirty
horse power engine, with common thirty
hve'foot cylindrical boiler. Relative tesls
with Cumberland coal show that the average
pressure OF steam with coal fuel under the
same boiler 10 thirty-nVe pounds; the coal
nres being raked out and the pumps started,
the pressure becomes reduced to twenty Ave
pounds. The gas nres then being started,
the pressure is increased to seventy pounds
In twenty minutes. This service is Der
formed at an expense OF one gallon OF crude
petroleum per hour-cost, II cents. The
capacity OF the present apparatus IL estl-
mated Al twenty thousand cubic feet OF gas
Per hour, equally adapted for fuel or for
Illuminating purposes. From the are thus
there is neither smoke, dust nSr ashes.
As a matter Of comparative economy the
results thus far seem TO be Of great promise.
Al the conclusion Of the exhibition the
party adjourned to Wormlsy's, where they
pRrtook OF one Of the choicest lunches Of the
season.
Hon. John II. Rice, OF Maine, presided,
and some very appropriate and entertaining
speeches were made, In which this invention
was CHASED with the telegraph, the locomo-
tive, and the printing prcIs in Its Importance
TO mankind.
Among those who spoke we're Judge

Virginia, Hon. Thomas Z. Stewart Of New
York, Colonel W. Il. Roberts Of Philadelphia,

Further progress with this invention will
shortly be announced, as there arc now under
contract ten new machines for this and
other cities, including New York and PhllR-
