NAVAL INTELLIGENCE.

NAVAL REVIEW.—We understand that, upon the
occasion of his Majesty the King of the French's visit to
this country, which is now finally arranged for the first
eek in September, a grand naval review will take place
in the presence of her Majesty the Queen and her august
visitor. As the flagships of the Port-Admirals, and
the experimental squadron, forming altogether 16 or 17
sail, will be cruising in the channel at this period, there
will not be the least difficulty in accomplishing it. The
ships which will then be at sea, will be the St. Vincent,
120, flag-ship, Admiral Sir Charles Rowley, Capt. R.
Rowley ; Caledonia, 120, flag-ship, Admiral Sir David
Milne, Capt. A. Milne ; Camperdown, 104, flag-ship,
Vice-Admiral Sir J. C. White, Capt. F. Martin ; Albion,
90,flag-ship, Rear-Admiral Sir H. Pigot, Capt. Nicholas
LoOcyer ; Collingwood, 80, flag. ship, Rear-Admiral Sir
George Seymour, Capt. H. Eden ; Queen, 110, Capt.
Sir Charles Sullivan ; Fox, 42, Capt. Sir R. M. Black-
wood ; Amazon and Dmdalus, frigates razeed to cor-
vettes ; Flying Fish, Mutine, Daring, Osprey, and
Espiegle, new class brigs of 12 guns ; Cruiser, 16, Pan-
taloon, 10, Waterwitch, 10, and a number of steam-
vessels.

The Queen, 120, Captain Sir Charles Sullivan, will be
paid off at Portsmouth, and not at Sheerness, as reported.
She will be refitted immediately for commissioncy, and
will form one of the experimektal squadron. We be-
lieve she is to be the flag-ship at the Nore, instead of
the Camperdown, which will be paid off. She has not
yet arrived, but is hourly expected.
_

The Apollo troop• ship, Co-mmander W. Maclean, has
arrived at Devonport from Quebec, with the service com-
panies of the 68th Regiment. She is since reported to
have arrived at Portsmouth.

The six iron steam-boats, building by contract for the
use of the Government as dispatch boats, are getting on
very rapidly towards completion, and will be ready for
launching in a few weeks.
The Cygnet, 10, Commander H. Layton, sailed from
Portsmouth on Monday, for the African coast.
Two line-of-battle ships will be commissioned in a few
days, ai,d, if completed in sufficient time, will join the ex-
perimental squadron. One of them is intended to relieve
the Illustrious, 72, flag-ship, Vice-Admiral Sir Charles
Adam, Captain J. E. Erskine, which is to return to Eng-
land, as the period of the Gallant Admiral's command
will expire in a few weeks. We hear that the Vanguard
will be one of the vessels commissioned.

The Formidable, 84, Captain G. F. Rich, with the
flag of Vice-Admiral Sir Edward Owen, is the only line
of battle ship now in the Mediterranean.
The Firefly, surveying steamer, Captain Beachy, sailed
yesterday for the Irish Channel, to resume her survey-
ing duties. There is no truth in the report that she was
destined for Tangiers with dispatches.
The Waterwitch was brought to Portsmouth, on
Tuesday, from Cowes, by the Echo steamer, to be masted
and fitted for sea.

The Prometheus, 5, steam sloop, Commander Hay,
sailed from Portsmouth, on Monday, for the coast of
Africa. She is to touch at Tangiers with dispatches for
the British Consul.

The Dee, steam troop ship, Master Commander T.
Driver, has left Chatham, for Cork, with the depot of
the 77th Regiment, under the command of Major Kelly.
The Pantaloon, 10, has been taken out at dock at
Portsmouth, and has received her masts.

The Sydenham, steam-vessel, Lieutenant D. Mapleton,
has been taken into dock. She is to have only two masts,
instead of three. Her mizen mast is to be taken out, and
her mainmast shifted further aft, in consequence of its
being placed too near the funnel.

INSTITUTION OF CIVIL
ENGINEERS.

JUNE IB.—The President in the chair.

A paper by Mr. Braidwood, superintendent of the fire
brigade, gave the results of his experience as to the best
means of rendering large supplies of water available in
cases of fire, and on the application of manual power to
the working of fire-engines. The author stated that if
water could be obtained at an elevatior, pipes with pine's,
or fire-cocks on them, would be preferable to any mode
at present in use ; and when this could not be obtained,
and the premises were of value, it would be advisable to
erect elevated tanks, to he kept constantly charged. When
water could be obtained, however, at not less than twelve
feet below the level of the premises, if it was not thought
prudent to erect elevated tanks, it might be conducted
beneath the surface by east-iron pipes, with Openings for
introducing the suction pipes. The system of covered
tanks the author believed to be the least advantageous
mode of supplying water ; and in many cases, where
the supply proceeded from large reservoirs, he thought
it would be better to place plugs or firecocks on the
water-pipe. The results of a series of experiments were
given, showing that the idea of extinguishing fires by jets
from water-mains, without the use of fire-engines, would
not succeed. They also proved the necessity of placing the
plugs on the mains, and not on the service-pipes, where
that could be done. The details were then given of the
mode of obtaining water from pipes or mains, and the ad-
vantages or disadvantages both of the plug and firecock
