THE PRINTING TELEGRAPH.

An engine having this title was exhibited yesterday
for private inspection, at the South Wester' Railway.
In the present instance it is made applicable to the pur-
poses of railway communications, but it may be made of
general utility. There have been many contrivances of
this kind, but the complexity of the machinery has hi-
therto interfered with their success. The invention in
question has the advantage of comparative simplicity,
both as regards its principle, and also as respects the
mechanism by which its utility is carried out. The eu-
gine is worked by the electric currents of the earth, and
these currents are produced by means of a plate of zinc
being imbedded in the earth at one extremity, from which
a wire communicates with a plate of copper, placed in
the earth at the opposite point. The effect of this is to
convert the earth between the two points into a voltaic
battery, and the value of this contrivance is that the
currents are constant, for, upon investigation, it has been
found that during the space of eighteen months there
has been, under such circumstances, no variation in the
currents. In all former telegraphs it was impossible to
tell if the message intended to be conveyed from one
point to the other were properly communicated. The
effect of the invention under consideration is, that the
intimation forwarded from one extremity is accurately
told at the other, or should a mistake occur, there are
instant means of remedying the defect. Another advan-
tage arising from the improved principle applied in this
case is, that the engine may he worked by attraction or
repulsion, by sending the electric current at rightangles to
invention
in permanent magnet. This is the principle oft he
in question. Its mechanism appears to be of a very simple
order. The engines, for there are two to work out the
principle involved in this invention, and they are placed
at either extreme of the points to be communicated with,
may be supposed to be powerful chronometers which go
together. This power is produced by the weights at-
tached to them, which are of 1001 b. ; and all that the
electricity has to do is to stop them at the required
figure, and the same operation takes into action an appa.
ratus that prints the same letter at both ends, and this
is produced on a revolving cylinder, which by the IN ay
is gradually elevated by a screw, so that the intelligence
is printed in a continuous spiral line until the paper is
full. To illustrate the value of this invention, it is only
necessary to say that if a party at one portion of a rail-
way is desirous of having post-horses at a particular
position on the line, he can have his desire carried out
with the greatest celerity through the medium of this
communication. Indeed such is the perfection of the
invention, that it may be locked up in a room, and
when the :person having the control of the apartments
returns, he will find any message that has been trans-
mitted to him in the meantime recorded on the paper
attached to the never failing cylinder. It may here be
mentioned that the wire from the engines can as well be
laid in the common earth as in ground used for the pur-
poses of a railway ; but the most secure way of carry-
ing the wire from one point to another is by laying it in
a bed of asphalte, which prevents it from being affected
• by dampness, which would draw the electricity from the
earth to the wire, and thus destroy the usefulness of the
invention. Upon the whole, we look upon " The
Printing Telegraph which is in operation between
Nine Elms and Wimbledon, to be a most useful and
valuable discovery, and well deserving the support of the
public.

[ADVERTISEMENT.] POST-OFFICE ARRANGE,
MENTS.—Worsdell's Vegetable Restorative Pills, pre-
pared only by John Kaye, Esq., of Dalton Hall, near
Huddersfield, have now, arising solely from their in-
trinsic merits, attained the highest celebrity, and be-
come the most extensively established Family Medicine
of the present day: but as many parties, anxious to ob-
tain this medicine, find great difficulty in doing so, owing
to many country towns yet being without an Agent,
from whom it can be procured; to obviate this difficulty,
the proprietor has now made arrangements by which
persons, residing in any part of the United Kingdom,
may be supplied with a single box, post free, direct from
the Wholesale Depot, in London, by forwarding fourteenin
penny postage stamps ; or, for the larger box. 2s.
stamps, addressed—liaye's Wholesale Depot, 44, Cole-
man-street, near the Bank, London.

ON DlTS.—Rumours of Sir James Graham's early
retirement from the Home-office are prevalent in weli-
informed circles, in which they are also credited. Such
an event is by no means improbable. As Secretary of
State for the Home Department, the Right Hon. Ba-
ronet has been singularly unfortunate. The fate of the
measures it became his duty to introduce to Parliament
has embarrassed the Ministry, and diminished the con-
fidence of the country in its efficiency. This has pro-
bably induced Sir Robert Peel to determine on placing
in that office one who may be more successful in the pre.
paration of measures, and in conducting them through
the House of Commons. The appointment of Sir James
Graham to India, as successor to Lord Ellenborough, is
revived in connection with the report alluded to. Others
refer the Right Hon. Baronet's reported early retirement
from the Home-office to chagrin—partly because of the
difficulty in which the Government has been placed by,
his unfortunate Factory Bills ; but principally to the re-
fusal of Sir R. Peel to recommend him to her Majesty
for the Lord Lieutenancy of Cumberland, which has
been conferred on Lord tonsdale, in conjunction with
that of Westmoreland. It is affirmed that Sir James
Graham was so confident of obtaining the Lord-Lieute-anoy of Clutbtritzti, as to have spoksr of his
