| --LATEST TRIUMPH OF SCIENCE ne perfece
success Of the Atlantic Telegraph has ecipsed
the spendor of an entirely new discovery in
the mysterious science Of electricity, brought
out By NIr. H. Wilde, Of Liverpool, during the
past year It is like the finding Of a nav con.
tincnt, the exploration Of which is sure to be
rewarded with vast and valuable acccSSlons to
the domain Of human knowledge.
Mr. Wilde performs his wonders by the com,
bination of six small permanent magnets weigh

netic machine, having an electro magnet weigh
ing three tons (which accumulates and retains
the de7e!oped electricity, On the same prlncl
pie as all insulated submarine cable or the
Leyden jar, and an armature revolving within
| an iron cylinder at the rate OF fifteen hundred
turns minute.
The effects are astonishing An arch OF
electric light several inches long spans the
space between the polar terminals of fixed car
bon. The light rivals the sun III its dazzling
righteousness At q distance Of d quarter Of Il
mile 1t throws shadows from the flames Of
street lamps upon wall. It beats the SUI at

was received with incredulity, but it is the
truth. Two enterprising photographers in
England have since put up the machines in
Their shops, and now do all their copying and
enlarglpg by the new electric light at night. OF
course the heating power Of the flames is in,

Now here, assuredly, is great discovery.
Nhat ls the tull scope OF the possibilities
opened ~ ii no one can tell, nor inteligently
conjecture. The cost Of the apparatus is small,
the waste OF materials lriaing, and where the
motive power Tor driving the armatures is al
ready at hand the expense OF working would
be nominal. The operation il continuous and
reliable, and the only objection brought against
the lnschlna is the noise caused by the revolving
armatuTes which could be obviated. A complete
machine made under the direction Of the

powers, which first presents itself to the mind

such lights would perfectly illuminate Broad
way from the Battery to Fourteenth street: at

clear weather The electric light is visible seven
miles further (27 to 20) than the best lights
ever before shown at those points. In thick
weather its advantages are still greater, as by
