To THE EDITOR OF THE y. y. SCN--Slr:
An eminent scientist of tins city, whose name
is withheld for the present, IS said to be- on
the point of puJ.ishinga series of important
discoveries, ana exhibiting an instrument in
vented by him, by means of which objects or
persons standing ar moving IN any part of
the world may be insantaneously seen any
where and by anybody. The utility o.! the
electrOSCOpe IS undenlahlC, and ii the invcn-
ton proves successful Il will SupeIceGe in
very Snort time the ordinary methods OF
telegraphc and telephone communication.
BY means of the elcclrocOpc merchants will
be able 10 exhibit their goods, or samples Of
them to any customer supplied with the
same instrument, whether in Liverpool, Lon
don, Paris, Berlin, Calcutta. Picking, San
Francisco, or New Orleans. Fugitive crimi-
mails placed in the c.cctroscopc can be in.
SANITY identified by the police authorities
in any part of the globe. Mothers, nus bands
and lovers will be enabled to glance at any
time at the very persons OF their absent chill
dren, wives, or beloved ones. Painters may
retain their paintings in their studio, and yet
exhibit them simultaneously all the CALLER
les Of Europe and America provided with the
invention. Scholars are thus enabled to con-
suit in their own rooms any rare and vaua-
able work or manuscript in the British Mu.
scum, Louvre, or Vatican, by simply request.

permit people, not only actually to converse
with each other, 10 matter how far they are
apart, but also to look into each others eyes,

Both telephone and electroscope applied on a
large scale would render ii possible to repre-
sent at one time on a hundred stages in varl
Gus parts of the world the opera or play sung
or acted in any given theatre. The actors
and singers will present, of course, certain
ethereal appearance, when thus viewed from
great distance, which, however. Will not
always prove really unpleasant to the audi
Cnce.
The invention is basel, as far as known, on
the pflnClplc OF transmitting tuc waves O4
light given ont by objects, in manner SINH
lar to the transmission of sound waves by
the telephone Everybody knows that the
sensations of collar which we perceive are due
to the varying strength and rapidity OF the
undulations Of light emanatlng from the OBJ
iects we look upon. Now, the electroscope
consists, to ali outward appearance, of two
empty boxes, or rooms, according 70 the size
required. One OF the compartments Is the
transmiltcr, the other the receiver. In both
compartments one side or wall presents the
ends of multitude OF quasi electric wires OF
peculiar make and consistency. Each OF
these iunumerabc wires transmits With the
utmost accuracy the faintest and strong
est undulations of every delicate or heavy
wave of color that strikes it horizontally from
some object or person opposite 10 1t. IhuS
many thousands of wires of the thickness OF
line carry cOnjontly the unduIations OF col
or cmanating from painting less than a 1907
square. The wires are twisted outside OF the
instrument into a cable, which may be eX-
tended tO its destination above or below
ground or through the water. On entering
the receiver the cable is UNFINISHED, and each
tiny wire is made to occupy again lis proper
position in the side or wall of the cOmpart-
ment The box, or room, acting as the re
ceiver, differs from the transmitler in beng
constantly flied with a newly discovered
gas, q sort of magnetic electric ether IN
which the currents of light or cOlOrs become
resplendent again, and by means of which
the objects or persons present at the time in
the transmittor are reflected as accurately as
in n mirror. ELECTRICIAN.
