MAGNETIC MOTOR.
Mr. Gary's Experiments about to De

IUti0n-One of the Obstacles
to the Electric Light
Removed.

Hartford COurGnt: The public has read
for some years with languid expectation and
more lnCreduliiy OF the experiments of Mr..
| Gary with magnetic motor. 1t has been
ready to accept almost anything wonderful
from the mysterious regions of magnetism
and electricity, but it wisely drew its line
short of perpetual notion" and settled
down on the belief that something" could
never be produced out of nothlng-that is,
that any valuable working power could not
5e produced without the expenditure of a
corresponding adequate force. But an illus
trated paper In the March Harper Monthly
shows that there was something In magnet
Ism that We did not knew, and that we are
probably on TIE eve of a great mechanical
revolution. Exactly what this is cannot
be understood without the accompany
ing cuts or a working model; but the
principle may be stated-and we give
1t at the risk of repeating what has
before been printed IN the newspapers. The
old way OF looking at magnetism, says this
article, has been to regard it as a force like
that OF graVitation, the expenditure of an
amount OF energy equal to its attraction being
required to overcome it, consequently its
power could not be used Mr. Gary has
found way to utilize what may be called
the stored and mysterious force Of the
permanent magnet. He has hit upon this by
long series Of practical experiments with an
ordinary horseshoe magnet, bit of soft iron,
and shingle-nall. The discovery is the ex-
lstence OF neutral line in the magnetic field
a line where the polarity of an induced
magnet ceases, and beyond which it changes.
This discovery upsets all the previous theories
OF magnetic philosophy, and lifts magnetism
from the position of a static force to that of a
dynamic force. And Mr.. Gary has actually
invented a simple continuance which furnishes
its own power, a power perfectly safe, the
cost OF which ends with the construction OF
the machine; a machine which, once started
by the finger, will run until it is worn out by
the force of fr1ction-as near to perpetual
motion as we shall ever get. And this ma
chine Is not mere plaything. To give an
enormous power the inventor has only
to use magnets OF large size. His first
discovery, resulting from his study of
the neutral line, only resulted in little ma
chine which secured continuous action, but
vas not a practical motor. A further study
Of the points IN the change of polarity led
hum to ms present success. His formal claim
IS this: Il have discovered that a straight
piece of iron placed across the poles of q
magnet, and near to their end, changes its
polarity while in the magnetic field, and be-
fore 1t comes in contact with the magnet,
the tact being, however, that actual contac!
ls guarded against. The conditions are that
the thickness OF the iron must be proper
toned to the power of the magnet, and that
the neutral line, or line of change in the
polarity OF the iron, is nearer or more distant
from the magnet according to the power of
the latter and the thickness of the former.
Ny whole discovery Is based upon this change
IN the polarity of the iron, with or without
battery. Power can be increased to any ex-
tent or diminished, by the addition or with
drawal of magnets. In all previous ma
chimes electricity is generated by revolving
piece Of soft iron IN front of the poles of a
permanent magnet. But to do this at
rate of speed high enough to produce sparks
IN such rapid succession as to keep up a stea-
