discovery of a new moter by Mr.,
Keely, of Philadelphia, has been ex-
citing the curiosity of scientific and
unscientific men for some time past.
There are those who consider it not so
much a new motor as chimera, which
is an assumption formerly arrived at
in regard to steam, the electric tele.
graph, and ocean navigation, they
were established by actual expert
ment There are others who insist
that it is the greatest discovery of thu
age, and is going to revolutronize tn
forces now employed in industrial
progress. 1t is unnecessary to say
that just as sanguine expectations
have been expressed before Of the re-
suits of inventions which have utterly
failed to realize the predictions of
their patrons.
Mr.. keely, We are told, however,
is about to demonstrate the entire
practicability Of his discovery in its
application to q railroad train be-
tween Camden and Jersey City. Any
expression of judgment, either for or
against, until we have this prac-
teal demonstration must be prema-
ture The public can afford to wait
till Mr.. keely submits his case to ac-
tual experiment.
1t is difficult to convey an intelli-
gent conception of what the alleged
new discovery is The motive princi-
pie is represented by the New York
Daily Bulletin "to be the expansive
power of carbonic acid, This impor-
tant compound, under a pressure of
thirtysiX atmospheres, at the temper
ature of thirty two becomes liquid
and when the pressure which retains
it in the liquid state is renewed the
rapidity of the vapor, are such as to
produce a degree of cold under which
acid solidifos, forming q white con-
crete substance possessed of very
extraordinary properties. Prof. Far
aday was the first who lliquifed car
bonic acid but it was first treated as
solid by w. Thilonrier. At COM
mon temperature and pressures water
absorbs its own volume of carbonic
acid under u pressure Of two atmos-
