Naval and Military Intelligence.

The Commander-in-Chief, the Duke of Cam-
bridge, reviewed the troops at Devonport yesterday.
His staff included the Adjt.-Gen., Lord W. Paulett;
the Quartermaster-Gen., Sir J. 11. Grant ; Military
Secretary Lieut.-Gen. Foster; Deputy Adjt.-Gen.
Col. G. Gambier ; and Col. Jervoise, R.E., Deputy
Director of Works. Lieut.-Gen. Sir A. Spencer,
Commander of the Forces in the West, was attended
by Brigade-Major Colley, Town Major Ramsey,
and Capt. Menter, aide-de-camp. The forces assem-
bled in the Brickfield included a field battery of six
guns, the 7th Brigade of Royal Artillery, the 20th
Regiment, 40th Regiment, and the Royal Marines.
Total—officers 132, rank and file 2,093. The forces
were divided into brigades, under Brigadiers Col.
Cormick and Cul. Foote, and Brigade-Majors Capt.
Scott and Capt. Mansell. The troops marched past
in slow and quick time, threw out skirmishers, and
went through various evolutions in a manner which
appeared satisfactory to the Commander-in-Chief,
who addressed them at the conclusion of the review.

Major-Gen. F. Murray yesterday completed the
half-yearly inspection of the troops under his com-
mand in the Chatham district, by the inspection of
the officers and men attached to the several depot
battalions who are quartered at Milieu barracks,
near Gravesend, for the purpose of going through a
course of instruction with the Snider rifle, together
with the detachments serving at Tilbury Fort,
Essex, and New Tavern Fort. Major-Gen. Murray,
who was attended by the officers of his personal
and divisional staff, proceeded early yesterday
to the rifle ground, near Shorncliffe, where
he inspected detachments of the let, 2d, and
3d battalions in the firing and ball practice, pro-
ceeding afterwards to Milton barracks, where the
troops were drawn up under the command of Col.
Stewart, in command of the detachment. After
inspecting the various corps, barracks, hospital,
canteen, and library, Major-General Murray after-
wards crossed the Thames to Tilbury Fort, and
inspected the detachment under the command of
Capt. Watson, Ist battalion Bth Regt., and in the
afternoon inspected the Royal Marines :Light In-
fantry, under the command of Lieut. Sweeny, at
New Tavern Fort, after which he returned to head-
quarters.

The departure of the 72d Highlanders from Alder-
shot to Manchester has been again postponed for
24 hours, in consequence of the barracks in the lat-
ter place not being ready for their reception. Ac-
cording to present arrangements the regiment will
now leave the camp this evening. The marching
out strength is as follows :—Major Hunter in com-
mand ; 33 officers, 39 sergeants, 24 drummers and
pipers, 530 rank and file, 62 women, 73 children,
and four horses. The men of the regiment left sick
in hospital are to be attached to the 56th Regt.
Col. Herbert, C. 8., Assist. Quartermaster-Gen.
at Aldershot, has been appointed Deputy Adjt.-
Gen. at the War-office, in the room of the late Sir
T. Troubridge, C.B. Col. Herbert's successor at
Aldershot will probably be Col. James Connolly,
unattached, formerly Cavalry Brigade Major at
Aldershot, and subsequently Assist-Adjt.-Gen. for
the South Western district, and afterwards at
Montreal.

OnTuesday Admiral Farragut went in the paddle
steam yacht Princess Alice from Plymouth Sound
into Hamoaze, and inspected Keyham steamyard
and other naval establishments.

Yesterday the Naval Commander-in-Chief at
Devonport, Admiral Sir Wm. F. Martin, accom-
panied by Admiral Superintendent Drummond,
visited Admiral Farragut on board the Franklin, in
Plymouth Sound.
His Prussian Majesty's new armour-plated screw
steam-frigate Frederick Carl, Capt. Koller, which
was built at Toulon, put into Plymouth Sound on
Tuesday. She left Gibraltar on the 17th inst., and
on the 20th, when crossing the Bay of Biscay,
carried away her fore and main masts. This acci-
dent is said to have arisen through various causes.
The masts, which were of steel, are said to have
been very long, and the wire rigging not sufficiently
stout. The iron keutledge i❑ her hold is not coun-
terbalanced by her armament, which will not be
placed on board until she arrives at Kiel. The
contractor who built the frigate undertooK to gua-
rantee the permanence of the masts for two years.
The Frederick Carl left at Gibraltar her Majesty's
ships Royal Oak and Prince Consort, and the Prus-
sia❑ ships of war llertl►a and Medusa.
The Swedish frigate Vanadis, 22, Commodore
Alexis Petersen, and the corvette Gefle, 8, Captain
Anton Rosengren, both from Carlskrona, arrived in
Plymouth Sound last night ; the frigate is bound to
Rio Janeiro, the corvette to the Mediterranean.
Her Majesty's paddle yacht Osborne, Commander
John D. Arcy, has sailed from Portsmouth for the
eastward, on special service.
The unarmoured screw sloop Rosario, 7 guns,
670 tons, 150-horse power, Commander Palmer,
arrived at Spithead yesterday morning from the
eastward, and remains at the anchorage awaiting
Admiralty orders.
The Plover, double-screw gun vessel, 3 guns, 663
tons, 160-horse power of engines, Commander
James A. Poland, the first of her class in her Ma-
jesty's Navy placed in commission, received orders
yesterday at Portsmouth to complete her stores and
outfit for a term of service on the West Coast of
Africa.

The Fox, screw storeship, Commander Henry A.
Moriarty, C. 8., is shipping hemp and other stores
at Portsmouth Dockyard for conveyance to the
eastern yards.
Her Majesty's paddle yacht Alberta, 391 tons,
160-horse power, is undergoing in the steam basin
of Portsmouth Dockyard the usual autumnal course
of repairs and re-embellishment, &c.
The Danae, 6, screw sloop, 1,268 tons, 350 horse-
power, recently tried at Portsmouth over the mea-
sured mile at her light draught of water, is being
brought forward as rapidly afi, possible for her trial
at load draught, and for commission. _ _ _

Her Majesty's unarmoured screw gun-vessel Myr-
midon having been completed at Chatham for the
first division of the Steam Reserve, in readiness for
commission, was yesterday taken to the Maplin
Sands for the purpose of making an oqicial trial of
her engines, and to ascertain her rate of speed, at
light draught, for classification. The Myrmidon is
one of the Wanderer type of vessels, with a length
of 185 ft. between perpendiculars, length of keel for
tonnage, 165 ft. 7in. ; extreme breadth, 28ft. 4in. ;
breadth for tonnage, 28ft. lin. ; breadth moulded,
27ft. Gin. ; depth of hold, 14ft. ; and burden, 694
66=94 tons. Although commenced several years
ago she remained on the stocks untouched until the
month of October last, when it was determined by
the Admiralty to complete her, and adapt her for
the new description of armament she was destined
to carry. For this purpose she was strengthened
throughout, her wooden deck beams removed and
patent iron Butterly beams substituted, while iron
stringer plates and angle-iron stiffening bars were
worked into her frames and topsides wherever prac-
ticable, the whole adding considerably to the stiffness
and rigidity of the ship. Tho engines and boilers
were fitted on board during the time the ship was
on the building slip at Chatham Dockyard. Her
machinery, manufactured by Messrs. Humphreys
and Tennant, of Deptford, consists of a pair of direct
acting horizontal engines, fitted with two cylinders,
each with a diameter of 31t. 6lin., and length of
stroke of 2ft. 2in., the connecting rod being cut off
short, as is peculiar to engines made by this firm.
There are four tubular boilers, heated by eight
farnaces, the weight of the boilers when filled being
37 tons. In the two high boilers the number of
tubes i 3 192, each 6ft. 6in. in length and 21 in. dia-
meter ; in the low boilers there are 97 tubes, each
6ft. in length. The screw is a single Griffith's pro-
peller, with a diameter of lift. 3in., and was set
yesterday at a pitch of 13ft. 101 in. With 100 tons
of the hand-picked Nixon coal and 10 tons of water
on board, together with all her guns, shot, and
cables, the Myrmidon's draught of water yesterday

on getting under way was lift. 9in. aft., and 10ft.
Sin. forward. During the trial the vessel was in
charge of Commander W. L. Partridge, of the Cum-
liorland, 70, guardship of the Steam Reserve, the
other officials on board being Mr. W. Eames,
assistant-inspector of machinery at Chatham Dock-
yard ; Mr. Owen, of the Steam Reserve ; Mr. W.
Hutchins, assistant-muter-4hipwright ; and mr,

Matthews, chief engineer of the ship. Mr. Hum-
phreys, of the firm of Humphreys and Tennant,
represented the makers of the engines, and had
charge of the machinery during the trial. On
reaching the trial ground six runs were taken at full-
boiler power, with the following results :-Ist mile.
—Time, smin. 35sec. ; speed in knots, 10.746 ;
pressure of steam, 221 b.; vacuum, 26 ; revolutions
of screw per minute, 100. 2d mile.—Time, 6min.
57sec. ; speed, 8.633 knots ; steam, 171 b. ; vacuum,
27 ; revolutions, 102. 3d mile.—Time, smin. Bsec.;
speed, 11.688 knots ; steam, 201 b. ; vacuum, 261 ;
revolutions, 106. 4th mile.—Time, 6min. 58sec.;
speed, 8.612 knots ; steam, 191 b. ; vacuum, 264 ;
revolutions, 106. sth mile.—Time, smin. 19sec.;
speed, 11.285 knots ; steam, 191 b. ; vacuum,
27 ; revolutions, 108. 6th mile.--Time, 6min.
45sec.; speed, 8.889 knots ; steam, 151 b. ; vacuum,
27 ; revolutions, 100; load on safety valve, 22k1b.
From these readings the moan average speed
of the ship was found to be 10.006 knots. During
the trial the force of the wind was 2, and the sea
calm. The temperature during the runs over the
measured mile was 90 deg. in the forward engine-
room, 79 deg. in the after engine-room, 104 deg. in
the forward stokehole, and 84 deg. in the after
stokehole ; on deck the temperature was 58 deg.
During the trial the boilers were found to prime to
such an extent, pressure of steam gradually falling
off, that the officials on board determined on not
proceeding with the trials any further, and the ves-
sel accordingly returned to harbour, where the ma-
chinery will undergo a general adjustment pre-
viously to the vessel being taken on another speed
trial. The Myrmidon has received her armament
on board, consisting of one 7-inch 6i-ton gun, and
one 64-pounder, on pivots, together with two 20-
pounder Armstrong breech-loading chase guns, and
the usual number of smaller guns for boat and field
service. There was comparatively little vibration
on board during the trial ; far less, indeed, than is
often observed in vessels of a much larger tonnage.
