Another Astonishing Inrention.--Ihe
Copying Telegraph.-There seems to be
no lmi, TO human ingenuity aud invention.
Before we cease to wonder at one triumph
Of human intellect and skill, we are called on
10 notice another still more wonderful. In
The London Spectator of the 18th uli., we
find the following notice of newly in
vented telegraph machine, in comparison
with which all former inventions are small
affairs:
The Postodfce superseded-Th Post
master General, Col. Maberly, and Mr.
Rowland Hill, may set their house in order,
and prepare to evacuale ST. Marlin's-le-
Grande; for they will soon have 10 exclaim
with OibeIlo: sour occupations gonem IL
seems, indeed, a hard case, after so much
hard labor to improve the postal communca-
lions of The country, and after steam has
done its utmost 10 hasten the mail-bags to all
paris Of the kingdom, that the well planned
arrangements and excellent machinery sh ould
come TO nought, bnt even they must submit
to fate and scientific invention.
Not many months have passed since we
noticed Mi. Bain's ingenious Marking Elec-
trio Telegraph, by me ans of which symbols
representing letters of the alphaber, are
marked on paper by electricity, and we pre-
dicted that means would soon be found OF
transmitting along the telegraph wires exact
copies of written communications. Whai
we then deemed probable has now been re-
allied. We have this week seen specimen
of writing by the Copying Telegraph invent
ed by Mr.. f. G. Blackwell, wherein words
traced from the original were legbly copied
on paper by an instrument that had no con-
nexion with the one to which the transmit
ed message was applied, excepting by the
usual wires from The voItaic battery The
letters traced on the paper appear of pale
color, on dark ground formed by numerous
lines drawn close together. The communi-
cations thus traced we understand, may be
transmitted at the rate OF 500 letters of the
alphabet per minute of ordinary writing; and
were shorthand symbols employed, the ra
pidny of transmission would be quadrupled
When this means of correspondence is in
operation, instead of dropping letter n,o
the poslOflce box, and waiting days for al
answer, we may apply il directly to the Cop
ying Telegraph, have il copied al the dis
iant town IN minute or less, and receive
reply, in our correspondents handwriting
almost as soon as The ink is dry with which
IL was penned. There various means, too
for preserving the secrecy correspondence
the most curious of which is, that The writin.
may be rendered nearly invisible in all parl
but the direction, until its delivery to ih,
person for whom il is designed.
The operations of the Copying TELEGRAPH
are not Limited to the tracing of written char
ac,ers. Letter-pr printing may be copies
with even greater rapidly than writing, ant
fac-simile copies Of the morning papers ma
thus be transmitted TO Liverpool and Man
chester long before the papers ihemselve
are delivered 10 their readers in London.-
The means by which these astonishing Ell
feels are produced We are not at presen
permitted TO Stale, as the invention is no
yet protected but we are assured thai Ih
method is simple, and that the mechanism i
neither costly nor likely 10 get out of order
il is, indeed, one of The peculiar features o
The Copying Telegraph that il cannot com
nit errors, because the communications
transmits are iac-similes of the original wr
Ting.
