THE NEW MoToRp
It is not safe 10 conclude with the !Gcten-
t!fc Anaeritan and the vast body Of incredu-
lous unsoient11o Americans that there is
nothing in KEELY's new motor-but fraud.
Flo was the most Indifferent Of smatterers
who, when a young enthusiast named A1oasE
went 1ecturing through the country to very
indi 1erent audiences about his now motor,
electricity, could not provo that tho telegraph
was in tie first place impious and in the soc-
ond impossible. It may be-we do not soy
that it ia so-that KELLY has found aome-
thing worth looking after. Ho is about to
apply hi8 invention, tho Eastern papers sny, To
propelling train between Camden and Jer-
sey City. His secret has not yet been au-
thoritativoly mado known, but It is said to bo
the expansive power Of carbonio acid gas. At a2
degrees Fahrenheit caEbonio acid isliquid un-
der pressure of so atmospheres. It can DO
solidi6od by being placed under greater pres
Eare in q froozing mixture. From this solid
proceeds vapor with tho most amazing ex-
pansiva properties. This subject has been
investigated by a correspondent Of tho So
7annnl, Ne'as, who gives tho following table !:
~ degrees Fnbrsnhsit the pressure In pounds Per
square inch II H71.
At 10 degrees Fahrenheit tho pressure in pounds psr
square inch II 403.
At % degrees Fshranheit the prtsaurs In pounds pr
aquare Inch il 4c1.
At 50 de1rsra Fahrenheit the pressure Ia pounds
squzre inch IL sou.
At 10 degrees Fahrsnheis tas pressure in pounds pr
squAre Inch Ia B07.
AZ Is degrees Fahrenheit the prsasurs in pounds per
square iueA II 1880.
Tie solidiAcation Of carbonio acid gaa VIVA
first achieved by Tn11oarEn, in Paris. The
strength OF tho gus may be Judged from the
fact TINT cast-iron apparatus Of enormous
strength burst during one Of his experiments,
killing an attendant. The bursting Of soda
water fountains, which sometimes happen,
is an instance Of the wonderful power
Of this gas. The mysterious casualty In Bos-
ton few woeKs ago, in which large tene-
ment building, the first floor Of which waa
occupied by drugstore waa blown to
atoms with great losa Of life, leaving no trace
Of the source Of mischiet, was beyond doubt
an illustration Of what KERLy's motor can do
IL left to itself. Tho reservoir Of carhonio
acid gas exploded. Hero is power for bo-
you'd that Of steam. Ia 1t certain that nothing
can be done to mako 1t manageable The
chomistries say that tho tension given Of by
the vapor from the Holidiaed gas is higher
than that from any other known substance.
They differ, apparently, with tho correspond
ont Of the Savannah -Nt,es quoted above, In
that they soy that tho tension Of the vapori ia
developed by lowering instead Of raising tho
Temperature, as usual with other gases.
Here isthe poworboyond doubt; has KELLY
harnessod It? We catch aresemblanco in the
description Of hta machine to tho apparatus
used by Tuuoa1RH. 4 hno hair tube playa
prominent part in the KEznx machine. TEL
1oa1En discovered that, II he allowed the
liquid gas to escape through asmall tubo Into
absasa box, an evaporation followed 80 pow
erfu1 that It solidiAed the rest OF the gas.
This solid Is tho seat Of the expansive powes
that the gas displays. cnrbouio acid gas ia
worry cheap 1t can be made out Of marble
and vinegar It Gun easily be l!queaed and
liqueaed, will freeze itself frozen, 1t can be
made to produce vapor " stronger than that
from any other known substance" Il Mr..
Kelly haa mol found out how to domesticate
this creature, soms other inventor will be
likely to do 1t before long.
