THE ELEoTR0sC0PE.

AcHIEvEMENr OF MODERN scIESSE?'
To TIE EDiToR OF The SUN-S1sr: An
eminent s,si ,sseiegtist Of this city whose name is
withheld he! for the present, is said TO be on
the, point Of publishing berries Of impor-
tant discoveries, and exhibiting aa instru-
meht invented by him, by means of which
objects or persons standing or moving in
any part of the world may be instahtaueous-
ly seen anywhere and by anybody. The
utility Of the electroscope is uudenia BILE, and
IT the Invention proves successful il will su-
persede in avery short time tho ordinary
methods of telegraphic and telephonic CON-
munication. BY means of the eicctroscope
merchants will hc,pbie rxhti1irs sirrfH Scodsl
or samples Of them, to any customer supplied
with the SAME instrument, whether in
Liverpool, London, Paris, Berlin, Calcutta,
Pekin, San Francisco, or New Orleans.-
Fugitive criminals placed in the elcctroscope
can be instantly identified by the police au-
thorities in any part of the globe. Moth
ers, husbands, and lovers will be enabled to-
glance at any time at the very persons Of
their absent children, wives, or beloved
ones. Painters may retain their paintings
in-their studio, and yet exhibit them sim
ultaneously in all the galleries of Europe
and America provided with the invention
Scholars are thus enabled to consult in their
own rooms any rare and valuable work or
manuscript in the British Museum, Louvre.
or Vatican, by simply requesting the libra
rians to place the book, opened at the de-
sired page, into this marvellous apparatus.
The electroscope will undoubtedly supersede
the ordinary methods of tclcgs1phy,. as II
matter, very little how long or how short
may be tho message transmitted by it; not
to speak of the advantage of being able to
read when desired, the original despatch in
the handwriting of the sender.
And further, in case the telephone, the
new instrument for carrying musical sounds,
should succeed also in transmitting ordinary
conversations, q combination of the electro
scope and telephone will be made which will
permit people, not only actually to converse
with each other, no matter how far they arc
apart, but also to look into each others eyes,
and watch their every micn, expression, ges-
ture and motion, while in the clectroscope.
Both telephone and electroscope applied on
large scale would render it possible to rep
resent at one time on hundred stages in
various parts of the world the opera or play
sung or acted in any given theatre. The
actors and singers will present. Of course,

ever, will not alwsys prove really uHpieasaat
to the audience.
The invention is based, as far as known,
on the principle of transmitting the waves
of light given out by objects, in manner
similar to the transmission Of sound waves
by the telephone. Everybody knows that
the sensations of color which we perceive
are due to the varying strength and rapid
ity Of the undulations of light emanaLiug
from the objects we look upon. Now, the
electroscope consists, to all outward appeaE
ancc, of two empty boxes, or rooms, accords
ing to the size required One of the com.
partments is the transmitter, the other the
receiver. In both compartments one side
or wall presents the ends of multitude OF
quasi wires of q peculiar make and
consistency. Each of these innumerable
wires transmits with the utmost accuracy
the faintest and strongest undulations Of
every delicate or heavy wave of color that
strikes it horizontally from some object OF
person opposite to it. Thus many thou
sands of wires of the thickness Of a line
carry conjcintly the undulatioDs OF colol
emanating from painting less than foo
square. The wires are twisted outside o
the instrument into cable, which may b'
extended to its destination above or below
ground, or through the water. On entering
the receiver the cable is untwisted, aud eacl
tiny wire is made to occupy again its prop
er position in the side or wall of the com
} partment. The box, or room, acting as tn
receiver, differs from the transmitter il
being constantly kept filed with newl
discovered gas, sort of magnetic electri
ether, in which the currents of light or co
or become resplendent again, and by mean
Of which the objects or persons present q
the time in the transmittor are reflected O
