Her horse power will be 400, by Penn and Son. She is
painted with a broad white streak with a black ribbon
above, and has a white ribbon round the upper part of
her gunwales; her figure-head being a very elaborately
carrel and gilded half-figure of a warrior in scale ar-
mour, the helmet surmounted with a furious flying dra-
gon—the figure has been much admired, as is the work
of Mr. Halm-, the artist.

Rear-Admiral Superintendent Prescott gave a sump-
tuous dejeuner to a large and distinguished party, in ho-
nour of the launch; and Mr. Finchsm also, with his ac-
customed liberality, entertained, at an elegant lunch, the
principal officers of the yard, and a numerous party of
ladies and gentleman.

The new slip from which the Furious was launched
yesterday, and on which the Marlborough, 120, will be
laid down immediately, is differently constructed from
411 other slip•. The other slips and docks rest on an
innumerable mass of piles, some of which are driven above
forty-six feet into the blue clay forming the under strata
of earth under the dockyard; but in this slip there are
no piles, and the granite floor stands on a thick mass of
concrete—the blue clay having been excavated, and a
depth of concrete, sixteen feet in thickness. substituted.
This appears to have formed a firm and steady founda-
tion, and the slip is as perfect as the day on which it was
finished.

Miss Erskine, in naming the vessel, drank " Success
to the Furious, and may she add more laurels to the
British navy, and long protect our gracious Sovereign,"
amidst the usual demonstrations of music and shouting.
The Master Shipwright afterwards gave an elegant de-
jetiner at his residence to the officers of the establishment
and a select party of friends.
To- lay being Prince Albert's birthday, the fleet in
commission here fired a royal salute at noon in honour of
the occasion, the ships being dressed in mast-head flags.
The Tartarus steam• vessel, Lieutenant Sir Godfrey
Webster, Bart., sailed this morning for Woolwich, to be
paid off.

Dauntless screw-frigate, Captain E. P. Halsted, has
bad her complement increased from 250 to 270; but
looking to her great armament and to her even compare•
tively light masts and yards, we do not think it likely that
she could ♦ery speedily get her complement of blue
jackets, if the Admiralty were to order her the comple-
ment of the Thetis—namely, 340. We feel assured that
on their Lordships' visit to this ship at Port month she
will be ordered to bo converted into a real and efficient
man of war—in masts, yards, and armament—and that
their Lordships will avail themselves of her great caps•
city and surplus displacement to get the most out of
her in power as well as in appearance.
Ex SMINATION OF Xi IDSILIPMEN.— A. new Admiralty
regulation has come into force since the first of the
present month, with respect to the examination of mid-
shipinen. Those midshipmen who have completed two
years' service, and have passed the examination required
by article 23, page 24, of the Admiralty 'instructions,
are to receive a certificate from the examining officer to
that effect; and no other officer will in future be
allowed to pass fur the rank cf lieutenant, unless he
has served a period of tiro yearsfrom the date of his cer-
tificate.

miralty have ordered the ordinary d,pots at the ports
to be paid off on the 30 h inst., and the newly nominated
sea-going, ships to be commissioned on the 31st
thu- : —At Portsmouth, the Illustrious, old 72 (mounting

Their Lordships arrived at one o'clock at the victual-
ling-yard entrance, and were received by Sir John Hill
the Captain-Superintendent.
The board consisted of Sir Francis Baring, Bart. (the
First Lord of the Admiralty), Rear-Admiral Berkeley.
Captain Sir Charles Milne, Sir B. Walker, surveyor of
the Navy, Colonel Green, and the Hon. Mr. Cowper.
After going through their inquiries in the Victualling-

Jolla Hill, and examined the vessels minutely, those in
the course of building, as well as the vessels under re-
pair, &c., and were highly satisfied with the results of
their inquiries.

At fo-ur o'clock the officers of each department were
mustered and examined, and subsequently the mechanics
and artisans assembled for a like purpose, and uader-
went a ri;id examination, after which their Lordships
took leave of the gallant Captain-Superintendent, and
retired thence on their way to town.

THREEPENNY and FOURPENNY COINS.

TO THE EDITOR OF THE MORNING CHRONICIE7-
Sir,-A recent correspondent has done useful service
to the public by calling attention to the increasing nui-
sance of two silver coins, so nearly alike in size and ap-
pearance as to be constantly given and taken promiscu-
ously, no matter whether by design or accident. As a
large issue of threepenny pieces is preparing at the
Mint, the evil will soon be much increased, unless the
fourpence is withdrawn, which it might very well be.
The only apparent advantage of two such small coins is
to put facilities for cheating into the hands of omnibus
conductors ; and this is practised to a very great ex-
tent. Allow me to suggest that, if both coins are to be
continued, one of them should be so distinct in form
as not to be mistaken for the other. Is it essential to
a coin to be round ? Wbere is the objection to an octa-
gon form ? It is as easily stamped as a round piece of
metal, and this would render mistake and deception im-
possible. A better remedy for this and the other in-
conveniences of our present money system would be the
carrying out of the decimal plan of coinage, of the many
advantages of which the public at present have scarcely
an idea.

A SUFFERER.

SINGULAR DISCOVERY or A BRIG SUNK NINE
YE:Axs AGO.—About nine years ago, as the Mary Scott, a
Liverpool brig, laden with copper ore and a general cargo,
an t having on board a large quantity of specie, was return-
ing from Valparaiso, she was run into, about dve miles east
of Point Lynas, by an American ship called the Brooklyn,
and the result was, that the Mary Scott sank in deep water,
and six or seven persons on board perished. Some time after-
wards the brig Parana,outward bound for Montreal, was run
down by the Iron Duke, and sank between Ormshead and
Point Lynas. No traces of either vessel were discoverable
until about three weeks ago, when a Liverpool fisherman
'
named Richard Price, whilst trolling near to Point Lynas,,
found that his net had become entangled to something be-
neath the surface of the water, and, on examination, disco-
vered that it had caught in the wreck of a vessel. It is not
positively known with which of the brigs the net became en-
tangled; but it is supposed that it is the Mary Scott; and
there is little doubt that it is with one of the vessels, as no
others are known to have gone down of late years in that
locality. The Liverpool Steam Tug Company have sent out
