The public has read for some years with
languid expectation and more incredulity of
the experiments of Mr.. Gary with a mag
netlc motor. 1t has been ready. to accept
! almost anything wonderful FROM the mys-
terious regions of magnetism and electrici-
ty, but it wisely drew it's line short of 'per.
petual notion" and settled down on the
belief that "somethiug" could never be
produced out of nothing-that is. that any
valuable working power could not be pro-
duced without the expenditure of cores
ponding adequate force.
But an illustrated paper in the March
Harper's Monthly shows that there was
something in magnetism that we did not
know, and that we are probably On the eve
of great mechanical revolution. Exactly
what this is cannot be understood without
the accompanying cuts or working model;
but the principal may be stated, and We
give it at the risk of repeating what has be-
fore been printed in the newspapers. The
old way of looking at magnetism, says rhis
article, has been to regard it as force like
that of gravitation, the expenditure Of an
amountof energy equal to its attraction be-
ing required TO overcome it, consequently
it's power could not be used.
Mr.. Gary has found way to utilize what
may be called the STORED" and mysteri-
ous force of lhe magnet He has hit upon
this by long series of practical expert
ments with an ordinary horseshoe magnet,
q bit of soft iron, and shingle nail. The
discovery is the existence of Q neutral line
in the magnetic feld-a line where the po-
larity of an induced magnet ceases, and
beyond which it changes. The discovery
upsets all previous theories Of magnetic
philosophy, and lifts magnetism from the
position of static force to that of dyna-
mic power. S2 e.
MIR. Gary has actually invented simple
contrivanca which furnishes its own power.
power perfectly safe, the cost of which
ends with the construction of the machine
machine which, once started with the
finger, will run until it ia worn out by the
force of friction---as near to perpetual mo-
ton 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 q. large size. His first dis
covery, resulting from his study of the neu-
tral line, only resulted in little machine
which secured continuous action, but was
not practical motor. A further study of
the points in che change of polarity led him
to his present success. His formal claim is
this:
~ have discovered that q straight piece
of iron glazed across the poles of a magnet,
and near to their end, changes its polarity
while in the magnet field, and before it
comes in contact with the magnet, the fact
being, however, that actual contact is guard
cd against. The conditions are that the
thickness of the iron must be proportional
to the power of the magnet, and that the
neutral line, or line of change in the polar
ity OF the iron, is nearer or more distant
from the magnet according 20 the thickness
