'THE ELECTRIC CLOCK
Among all the wonders of that wonder-working prin-
ciple, electricity, whether we view its powers in the in-
stantaneous.conveyance of information between distant
places, its
"agency in blasting rocks in safety, the depo-
sition of metals from -their solutions, or others of its
numerous appliances, there is not one of them which
strikes the mind as ,more extraordinary or interesting
than its application as.to prime mover for the measure-
ment of time. In thiss- however- it has now become
.most completely successful, and insures a correctness
and regularity which cannot be obtained by other
clocks, however well constructed. We believe
the first idea of working clocks by electricity
is due 'to' Mr. Alexander Bath, who '"first commenced
putting it in practice in 1838, His first attempt was to
make a common clock transmit its time to other clocks
at a distance, effected by the action of electro-magnets,
in which he' was perfectly successful. The next step
was the application of the electric power to work single
clocks, so that no winding might be required, and the
common block dispensed 'with altogether. This, in a
commercial point of view; was of great importance, as
such a clock, either for private houses or public build-
ings, could be used either singly or made the governor
or parent clock to other dials in different parts of the
building. The ordinary galvanic apparatus was found,
however, neither uniform or lasting, giving more trouble
and expense than the common clocks; and in prosecut-
ing his experiments, Mr. Bain, iu 1842, discovered that
a plate of zinc and one of Copper, buried in the earth,
gave a uniform and continuous force of sufficient power
to work clocks of any size, from the smallest mantel
time-piece to large church °lecke.
In the construction of an electric clock, the pendulaal.,
rod is of wood and suspended to a metal bracket, fixed
to the back board. The bob of the pendulum is com-
posed of a. reel of insulated copper wire, with a brass
covering to improve its appearance, forming an electro-
magnet in the usual manner. The ends of the wire are
carried up the rod, terminating in two suspension springs,
which nerve the double purpose of suspending the pen-
dulum, and conveying the current to and from the bob.
Two brass tubes contain each a bar of magnetised steel,
and act as alternate attractors to the bob. There is a
break ou the pendulum for letting on and cutting off the
current, which acting on the bob, operates also on clocks
at distant pieces. The plates of zinc and copper are buried
about 4 ft. underground, and 3 ft. apart, and to them per-
fectly insulated copper also are soldered. A regulat-
ing weight being attached to the pendulum to bring it to
time, the apparatus is complete. For the motion on the
dial plate, only two wheels and an endless screw are re-
quired, besides the minute and hour wheels; and the
clock instead of moving the pendulum, being on the con-
trary moved by. it, a much smaller degree of stress and
friction is the result. The pendulum once set in motion
acts on the break; and the current being, as we have
shown, alternately cut off and admitted, regular motion
is obtained, which will continue for many years.
In situations where it is inconvnient to obtain the
electric current from the earth the voltaic battery
is resorted to ; but in almost every case the first
mode has proved the 'easiest, as well as the most
effective. The coat of its plates is a trifle, and it has
been ascertained that they will retain their
efficacy far years. The advantages of this application
of electricity to another of our wants it is scarcely pos_
sible to estimate, as through the medium of auxiliary
clocks, exact time may be kept through a whole neigh-
bourhood, or, in short, to wherever wires can be laid
down. Ia fact it is now shown to be possible that all
the principal clocks in the kingdom might bo united to
keep time with one governing one, which, again, derives
its moving power from the earth, without winding up or
need of attendance of any kind from one year's end to
another.

Mr. Bain's warehouse for these olock9 is at 43, Old
Bond.strett; and we think an inspection of them is de-
serving the attention of the seientitie.-111ining Journal.

IMMENSE VONSIGNMENTS OF IiOLD FROM Aus-
TRA.LlA.—Yesterday, information was received of the arrival
of the barque Posthumous, Davison: master, off Beachy
Head, from Melbourne (Port Philip), which she left on the
16th of March, and Port Philip Heads on the 18th of March.
The Posthumous landed the mail 3 at Eastbourne, and pro-
ceeded for Loudon. She is laden with wool, oil, and a
at Melbourne from the digg
in these,
quantity of gold, which is supposed to be the largest consign-
two tons per week. I bring home a freight, and amongst
ment yet made from the colony. A letter has been received
of tht
from Captain Davison, in which he says, ” Gold was arriv-
ingi,gs at the rate of about
ible gold regions." A

great number of ships, the cargoes of which have been em-
barked, were detained for want of seamen, the greater por-
tionthe digging;, where many are doing well. The Vanguard
and Benjamin Heape are loaded and waiting for seamen in
Hobson's Bay. The amount of gold consigned to and re-
ceived in the port of London during the past week ap-
ppaches 500,0004 six wosseis—viz., the Wellington,
1 homas Hughes, and Syria, from Port Philip, the Wands-
worth and Regina from Sydney, and the Britannia from
Portland Bay—having brought home 53,623 ounces of the
precious metal, and the remittances received from the
colony within the last three weeks exceed 1,250,0001, a i value.
