VALLETTA, Nov. 6.—Her Majesty's paddlewheel
despatch vessel Psyche, 2, Lieut.-Com. A. R. Blane,
arrived on the 2d inst. in tw) days from Naples,
and is riding out her quarantine in the Marsamu-
seetto harbour. She brought news that the ViCtoria,
102, screw line of battle ship, bearing the flag of the
Commander-in-Chief Vice-Admiral Sir R. Smart,
K.C.8.), which left Naples under sail on
the 30th ult., might be expected that afternoon.
She did not, however, make her appearance until
this morning, and is now entering port. The
Gibraltar, 81, screw line-of-battle ship, Capt. R.
Coote, and the Racer, 11, screw corvette, Corn. L.
Brine, had been despatched to the lonian Islands and
Greece for the protection of British interests, in
consequence of the excited state of the country. The
Royal Oak, 35, ironcased frigate, screw, Capt. F.
A. Campbell, arrived at Malta on the 4th instant,
having on board as passengers Sir J. Doraville and
Lady Doraville. She was last from Syracuse, where
she left on the 3d inst. the Caledonia, 31, ironcased

screw ship, Capt. the Hon. F. A. Foley (flagship of
Rear-Admiral p. R. Yelverton, C. 8.), and the
Resistance, 16, iron screw ship, Capt. W. C. Cham-
berlain. The Enterprise, 4, ironcased sloop, screw,
was at Palermo. It was generally believed on board
the Royal Oak that Rear-Admiral Yelverton would
soon repair to Malta to replenish stores. The Pelican,
17, screw corvette, Commander R. P. Cator, com-
pleted her 10 days of quarantine this morning, and
was admitted to pratique. The Phoebe, 35, screw
frigate, Capt. W. R. Rolland, will be out of qua-
rantine to-morrow. The arrival of these vessels
from Naples has already been reported. On Nov.
2 a court-martial was held on board her Majesty's
ship Hibernia, to try Gunner Winburne, Royal Ma-
rine Artillery—l, for breaking out of H.M.S.
Orlando ; 2, for striking a non-commissioned officer
while under arrest ; and 3, for abusive language to
the wardroom officers. Capt. White, of her Ma-
jesty's ship Cossack, presided, and Mr. Goddart,
Assist. Paymaster of her Majesty's ship Orlando,
officiated as Crown Advocate. The prisoner was
found guilty, and sentenced to receive 48 lashes, to
be reduced to the second class, and to be imprisoned
for 12 months in Lewes Gaol. Our harbour is again
assuming its lively appearance, from the presence of
a large portion of the fleet. The following is a com-
plete list of the ships of war now in port :—The
Victoria, le (flagship of Vice-Admiral Sir Robert
Smart) ; the Hibernia, receiving-ship (flagship of
Rear-Admiral 11. Kellett); the Royal Oak, 35, iron-
clad ; the Orlando, 46, screw frigate ; Phoebe, 33,
screw frigate ; Cossack, 20, Chanticleer, 17, and
Pelican, 17, screw corvettes ; the Assurance, 4, and
Surprise, 4, screw gunvessels; the Psyche,2,despatch
vessel ; the Wizard, 2, and Cockatrice, 2, screw gun
boats ; the Azoff, sailing tender ; Hearty, tug ; and
Weser, paddlewheel gunvessel (dismantled).
Foreign.—Russian frigate Peresvet,4s, and Tuni-
sian screw steamer Mahersia.

The iron-cased screw steamship Lord Clyde, 24,
was taken outside Ply-mouth Sound on Saturday to
make a trial of her engines, under the inspection of
Captain Edmonstone, C.B. Mr. Steil, assistant
engineer from Keyham Steam-yard ; Mr. Dinnen,
Inspector of Machinery Afloat ; and Mr. Saunder 3,
Second-Master Shipwright, were present on the part
of the Admiralty. Mr. Ravenhill represented the
manufacturers of the engines. In consequence of
bad weather she was only able to make two runs at
the measured mile, but these, considering her pecu-
liar construction, were very satisfactory. The Lord
Clyde was built at Pembroke on the lines of Mr.
Reed, Chief Constructor for the Navy. She is 280 ft.
long, 58ft. 9in, broad, and has. a depth of hold of
20ft. 9in. ; her burden is 4,067 tons. Tier engines
are fitted with cylinders of very large diameter for
the purpose of using the steam expansively, also
with surface condensers, superheaters, and tubular
boilers, having brass tubes 2fin. outside diameter,
and containing an aggregate heating surface of
19,000 square feet, with a great surface of 700 square
• feet. There are nine boilers arranged in two groups,
one of four pieces and the other of five, each group
having a chimney 7ft. tin. in diameter. The engines
are capable of exerting an indicated power of 6,000
horses, being a multiple of 6 to 1 of their nominal
power, and, as closely as their requirements would
admit, are of the same style of double piston rod
engines as those made by the same firm with ordi-
nary condensers, which are well. known both in the
British and foreign navies. They are a pair of
direct-acting horizontal engines, with double piston-
rods, having cylinders of 116-in. diameter, with a
stroke of 4ft. Each cylinder weighs upwards of
30 tons, and the crank shank weighs 25 tons. The
slide valves are placed vertically on the outside of
the cylinders, and are worked directly by means of
a solid link motion. Although the cylinders are
brought well towards the fore and aft centre line
of the ship, there is ample space between the
connecting rods and the cylinders for getting to the
glands of the stuffing-boxes of both the piston rods
and the air-pump rods, which latter are worked from
the main pistons of the engines. The connecting
rods are 9ft. Sin. long, being seven times the length
of the crank.. The air-pumps and the foot and de-
livering valves, which are of india-rubber, working
on brass seats, can be easily examined and removed.
The feed and bilge pumps, in brass, are fitted with
indiarubber valves, and worked direct from the cross
heads. Gridiron expansion valves are also applied,
and are worked directly from the shaft by means of
eccentrics and rods. The condensers are fitted on
Hall's system, with vertical tubes, the end of every
tube having a small stuffing box and packing gland,
both in.the top and bottom tube plates of the con-
densers. The condensing water is circulated by
means of two centrifugal pumps, one to each con-
denser, which are worked by a pair of independent
donkey engines. In addition to the ordinary start-
ing gear, steam cylinders are fitted to facilitate the
handling of these large engines. The machinery is
fitted with a four-bladed propeller, fixed on the
stern shaft. The cylinders are the greatest in dia-
meter, and the engines therefore the largest that
have yet been supplied to the British navy. The
draught of water of the Lord Clyde was forward
22ft. 4in., and aft. 24ft. 10iu. The vacuum in the
condensers forward 27in , aft 28in. Speed, first run,
4min. 26 sec. ; second, 4 min. 26 sec., equal to
13.533 knots per hour. The speed of the screw was
12.825, showing a negative slip of .708, or nearly
three-quarters of a knot. Revolutions first run,
55i. per minute ; second, 56; indicated horse-power,
6,110 ; nominal, 1,000 ; propeller, four bladed ; dia-
-Meter of screw, 23ft. ; pitch, 22ft. Gin. Wind north
east, force Ito 2. Sea smooth. It has been gene-
rally feared among naval officers and others that
owing to the construction of the Lord Clyde with a
long protruding prow, armed with a heavy mass of
metal, it would be impossible to realise a speed of 13
knots ; but the result of the trial has demonstrated
those fears to be groundless. The engineers are
confident that when the vessel can have the ad-
vantage of making the usual six runs under cir -
cumstances of certain slight modifications in the en--
gines that still better results will be obtained, and
that a speed of 14 knots will be realised. The speed
of the Lord Clyde is, however, already in excess of
any vessel of at all similar dimensions.
Her Majesty's 6 gun paddle sloop Spiteful, 1,054
tons burden and 280 horse power, commissioned at
Woolwich by Commander W. D. Fletcher on the
6th inst., Yesterday commenced receiving her furni-
ture and sea stock. Her crew were also transferred
from the flagship Fisgard, and every effort is to be
made to expedite her departure to her destination—
the coast of Brazil.
The War Department steam storeship Lord Pan-
inure arrived at Woolwich yeaterdayfromPorts-
mouth and commenced discharging her cargo
at the
Royal Arsenal.

Yesterday morning the battalion of ei
—renadir
Guards, now quartered at the Sheet-street barracks,
.
Windsor, marched, under the command of Lieut.-
Colonel Higginson and Capt. Lord Hinchingbroke, ,
to the Home-park, where the troops had a field-
day. The battalion, consisting of eight companies,
went through a number of evolutions, which, with
the firing, were extremely well executed. At the
conclusion of the movements the troops were
marched back to their quarters, with drums and
fifes playing,
