: WlrA NEW MOTOR
For some time past the scientific and
u~nscientifc have been exercising their
curiosity with reference to the alleged
discovery OF q new motor by a Mr..
Keely, OF philadelphia, who, we are
told, Is about t demonstrate its entire
practicability in its application to a
railroad train between Camden and
Jersey City.
Until We have this practical demon
stration it is quite clear that any ex-
preston Of Judgment as to whether it
il all THAT tho discoverer and his friends
claim it to be, is premature, not less
than the off-hand assumption of some
Of our contemporaries, who can really
know little or nothing about it, that
the alleged discovery is not so much a
new motor as q chimera. The better
way is to wait and see. If. Mr.. Kelly
can prove his case, he is entitled to his
opportunity, and also to q suspension
of Judgment until the facts are all
in"
Meanwhile, it is not an easy matter
to convey to the lay mind an entirely
Ineligible conception OF what the al
legged new discovery is, Invested of the
scientific technicalities and phrases
which necessarily attach to such SUBJ
jects. The motive principle is repre-
sented to be the expansive power of
carbonic acid. This important COM
pound, under a pressure of thirty-six
atmospheres, at the temperature Of 80
becomes liquid; and when the pres
sure which retains it insthe liquid state
is renewed the rapidly Of the evapor-
alton and the enormous expansion Of
the vapor are such as to produce a
degree Of cold under which acid solid
lies, forming q white concrete sub
stance, possessed of very extraordina-
~ properties. Prof. Faraday was the
first who liquifed carbonic acid, but it
was first treated as q solid hy w. Thil-
onrier. At common temperature and
pressures, water absorbs its W vol
ume of carbonic acid; under a
pressure OF two atmospheres, it
dissolyes twice its volume, and
90 on. An intelligent correspond
emit of the Savannah News, who
claims to have made and
expensive experiments with it, has no
doubt of its immense power as a me-
chanical agent; in 1proof of which he
adduces the following progressive aug
mentation Of its expansive properties
by increased temperatures:
At S degrees Fahrenheit the pressure
in pounds per square inch Is 372.
At 10 degrees Fahrenheit the pres
sure in pounds per square inch is 403.
At 20 degrees Fahrenheit the pres
sure in pounds per square inch Is 400.
At 30 degrees Fahrenheit the pres
sure in pounds per square inch is 500.
At 40 degrees Fahrenheit the pres
sure in pounds per square inch is 697.
At As degrees Fahrenheit the pres
sure in pounds per square inch is 1850.
Heretofore the great scientific diff
Guilty has been to know how to utilize
this wonderfully expansive power-to
put the harness on it, so to speak, and
work il, as Professor Morse has har-
messed electricity, and compelled it to
carry messages. Now, Mr.. Keely
claims, this difficulty has at length
been conquered, and people who pro-
fess to have patiently examined his
plans, and listened to the description
Of his generator, multiplier, receiver,
pipes, etc., are confident he will sue
coed. The advantages claimed for il
over steam and the steam engine are
many, not the least Of which are
economy, safety aud easy control. i
applied to navigation the propelling
power, 1t To said, would not EOS NOR
than five dollars to run a steamer from
savannah to New York; and rs thu
necessary machinery will not take vi
one-fourth part Of the weight and
room Of . boiler, engine and fuel, o
equal power, another advantage would
be additional carrying capacity anG
space for freight.
We trust Mr.. Kelly will be able te
demonstrate all he promises. The
rapid industrial, commercial and socia'
progress Of the world in these days
would make q new motor universally
acceptable II it will help to cheaper
transportation and travel on the rail
roads, and help to do the work of thu
mills and manufactures. Steam and
electricity are executing their mission
In these respects marvelously; but II
nature has any other forces which mar
can press into his service, their discov
srsr need not be discouraged by an ap
prshsnsion that there will be no EN-
ploymsnt for them.
