NEW yoLTAIC PILE

Fus ia the employment Of iron instead Of zinc and III
Die arrangement Of the charcoal or copper discs which
are circular and placed On spindle; as they revoise
onehird Of their surface is covered with The ud III
the cups The exciting liquid is water containing per
cent al nitric acid.
NEW PLAN FOR ILLUMINATION.
NJ SounHA has applied the principle Of downward
draft IL light by which the fame is inverted. 1ls ~
accomplished by means Of n glass syphon having its
open ends turned upward. The longer branch is at
top of the shorter branch is drawn downward The
gsses OF combustion pass around the curve and
through the longer branch which is consequently kep'
hot md the draft j. thus maintained. Tie only ad'
vantage Of this arrangement is In having oil the az
tachments above the flame 30 as not u cast sna'o"
below.
PAPER BouFRe
NJ TERRELL has reported 90 the Paris Chemical So
cio;y curious facts regarding paper subjected to very
high heat upon side when water Is placed on the
other Paper being slow conductor OF heal ihere Is ~
reality an osnoc process carried on by which water
containing metallic salts is passed through, and tn
salts are reduced by the flame.
Ia relation the item on the manufacture oil sulphur,
Mr. EYoe STEVENS stated that Italy Was he source ol
moot of the sulphur used in this county. IL was I'm
ported from Sicily as ballast in vessels Laden WIN
oranges -, o.,
no.,ol.un would be the source OF considerable sulphur
lie had obtained hall barrel of sulphur from 40 bbl'
of Canada rock oil.
THE USE OF TuE yAPog or WATER WITH FUEL
Mr. T. d. STfT~oy opened the debate by saying The
subject mad already called forth considerable sPsou'"
uon. We have Instances ol the practical value 81
burning water with other materials Ia the ease Of burn
ing " Il sugar cane bagasse and wet tan-5arA and
vet sawdu.t in furnace especially adapted 10 that pur
plsc. In these cases the water performs the simple
iur elton Of changing the mechanle character Of Tie
fuel So also a. the case OF burning vet ashes now
those are cases Of the burning ui vat sufficient u
establish the fact and the utility arising RON ihs noie

We now come 10 the subject Of deoomPcslng water.
When Wgtr is boiled W. make steam aid II the steam

steam but simply heating the water does hot deo"n'
pose it into is original elements This can, however
be done by passing steam through red DO, IRON PPe
hen the oxygen Of the water viii unite with The iron
and the hydrogen ~ the wnier will be set free II steam
Is parsed through heated carbon IN the shape o burn
NJ Goals there il doubt that i aids combustion and
the theory Of IL is this the hot bed Of oos- does not
