Naval and Military Intelligeipe.

A new screw steam 4-gun vessel, called the Reynard,
was launched yesterday morning at Messrs. Mare's
building establishment, and taken to Messrs. Fletcher's
to receive her engines, of 200• horse power, after which
she will be equiqped and fitted out in Woolwich dock•
yard.
The floating battery Thunderbolt, launched at Mr.
Samuda's, Rackwall, is expected at Woolwich to-day,
and will be immediately placed under the hands of the
shipwrights, to be equipped for service.

The 'iron paddle-wheel steamer Antelope, and the
steam-sloop Ardent, in the inner basin at Voolwich,
were yesterday dismasted, in process of carrying out the
necessary repairs, required on an extensive scale.
Although it is understood to be the intention of Go-
vernment to despatch seven regimpts of the line from
the East to Canada, the order is said not to be compul-
sory on individual regiments, but that battalions for such
destination are to be composed of volunteers from the
whole army. The aggregate strength of the regiments so
formed will be about 10,000 strong. With regard to the
shipping of ammunition from Woolwich for Canada, the
authorities have decided that, as a very large quantity
now etored in the Crimea will have to be removed the
most expedient plan will be to convey it thence by means
of line-of-battle ships intended to transport the troops;
consequently, the department at Woolwich Arsenal has
received orders to discontinue the preparing and casing
any powder and ammunition there for transmission to
Vaned% as directed a short time back, the order having
been rescinded.

The following appointments have been made at the Ad-
iniralty:—Edwd. W. Laing to be Flag Lieutenant to
the Black Eagle, to the Board of Admiralty ; the Rev.
John L. Moore to be Chaplain to the Retribution ; C.
B. Lamb and James Mitchell to be Assistant Surgeons
to the Calcutta.

Orders were unexpectedly received on Tuesday for all
the troops in garrison in Plymouth to assemble on the
Hoe yesterday, at 11 o'clock, to receive Major• General
Eden, Commander of the Forces in the Western District,
and to be paraded in contiguous columns at quarter dis-
tances, in review order, the troops to be commanded by
Col. H. Pester, Royal Artillery. They consist of about
5,000 man—viz., Royal Artillery, Col. Pester, from
Devonport and Drake's Island; Devon Militia Artillery,
Major W. Hole, from Devonport ; Royal Marines, Light
Infantry, Colonel-Commandant Childs, from Stonehouse;
Depot of the 94th Regiment, Major H. G. Buller, from
Devonport ; South Devon Militia, Major Sir H. Seale,
Plymouth Citadel ; Royal Limerick Militia, Col. Sir R.
D. De Burge, from Devonport; the Ist Warwickshire
Militia, Major C. Wise, Plymouth Citadel; 3d German
Jager Corp, Col. H. 0. Bowles, from Maker Heights
and Bovisand ; and the depot of the 62d Regiment, un-
der Col. G. Maxwell, from Devonport.
Some engineering experiments of a novel and interest.
ing description took place at the practising ground at-
tached to the Royal Engineers' Establishment, Brompton
Barracks, on Monday night, commencing at about 12
o'clock, and terminating shortly before 3 o'clock on
Tuesday morning. A large nun'ber of men belonging
to the corps of Royal Sappers and Miners were engaged
in this night attack, the object Col. Sandham, director
of the Royal Engineers' Establishment, had in view be-
ing that of carrying out a plan by which frequent sorties
from a besieged town upon the besiegers may be turned
against the attacking party. The frequent sorties made
by the Russians upon the trenches before Sebasto-
pol have presented to the heads of the engineering de-
partment important reasons for practising the troops in
experiments in order that the enemy may be thrown
into confusion, and advantage taken of the failure of the
attack. The whole of the experiments on Monday night
were considered to be perfectly satisfactory ; and, not-
withstanding the lateness of the hour, were witnessed by
a considerable number of spectators. Some other experi-
ments upon an extensive scale and of a novel and inte-
resting nature are expected to be undertaken by the
Royal Sappers and Miners, at St. Mary's-creek, in the
course of next week.
