GREAT MAGNETo-ELECTRIC MACHINE.

Prof. PACE of the Patent Office has presented his great
Magnetic Electric machine the Smithsonian Institution,
which, together with its accompanying electro magnet forms
one of the most prominent and interesting objects the
cabinet of philosophical instruments BY the simple Of
crank powerful electro magnet produced capable
of sustaining nearly thousand pounds This is the
machine that worked Moses telegraph in 1884, and was at
that time exhibited successfully the Presidents Cabinet and
others, the Patent Office, when exploded gunpowder
through several hundred of by the ignition of pIa
tnum wire
This machine constructed with reference the maxi
mum Of quantity Of electricity to be obtained by magnetic
electric excitement and with several distinct purposes in
First to determine whether the electricity obtained could
be sufficient to operate electromagnetic engine, which
in its should furnish sufficient mechanical power keep
the magneto-eectic machine notion Ii was never tested
for this purpose but Prof Page believes this may be
pished and that although would be generally regarded
perpetual motion, yet it could lay claim this
strous absurdy if successful for the steel magnets would
finally degenerate power and the machine be stopped The
magnets would act only reservoir of power, which would
finally become exhausted; nevertheless if it could be done,
it would be the interesting mechanical feat
performed
second purpose of Prof Page in this invention to
superede the gavanic battery in teleRraphng the design
being to keep the machine in motion by means Of clock
work. +ses
Lastly it was designed 10 supersede the battery generally
for practical purposes particularly for blasting distance
The quantity oeecircy has been fairly measured but
is somewhat remarkable tina. its intensity low that
gives shock whatever and its dscomposng power very
feeble. The pecuay Of this machine is mainly in the
struction of the helices which Prof. Page described
years since in the Franklin Journal 1t is worthy of note
here that three four years after this publication person
in England took out paen for the identical mode Of
structing helces for magneto- electric machines.
About the time that the above machine was made,
Prof Page also exhibited at the Patent Office large COM
pound magnetoectc machine made with reference to the
intensity Of electricity developed this wsy and for the
pose of decomposng obtain its gases combustion
and illumination.
This machine in its entire was renvented by
the distinguished Prof. WHEArsrosE several years after in
England, and described in Daniels Introduction to Chemis-
try The highest performance Of Pref Pages machine
the production of ten cubic inches Of mixed gases per
minute.
Another interesting piece Of apparatus which peased
to see Prof. Page has presented the institution illus
trating his discovery of the vibration of Teeans bars by
galvanism.
These contributions from the liberal hand OF Pfof Page
cannot fail to add the of the cabinet Of this great
institution, and aid urtherng the design OF the mun-
testator.
We cannot fobear in conclusion state that Prof. Page
will add these already valuable gifts that of his earlier ma
Chimes made in the of his last and grandest effort
the production of power by The gavanc current But few
years will pass when these machines will be viewed with as
much interest well remember to bave exhibited in
the Roy Library of Berlin in The inspection of the two hemi-
spheres for illustrating atmospheric by Otto Gdercke.
