THE NAVY.

The Marlborough, 131, screw, Capt. W. H. Stew..
art, C. 8., sailed from St. Helen's Roads for the Me-
diterranean early yesterday morning.
The Indomitable sailing transport sailed from
Spithead with the remaining portion of the 2d bat-
talion of the 11th Regiment, yesterday, for the Cape
of Hope.
The Roebuck, 6, screw, Commander Marten re-
cently returned from China, will pay off her crew
and be put out of commission at Portsmouth to-day.
The Princes Philippe and Auguste of Saxe-Co-
burg yesterday visited the various points of interest
in the dockyard at Portsmouth.
The Pylades, 21, screw steam corvette, Capt.
Michael De Courcy, arrived at Spithead from the
Pacific yesterday at 4.30 p.m. She will probably
sail for the eastward to-day.
A renewed trial was made yesterday at Ports-
mouth dockyard of Mr. White's diving cylinder and
air pipes. The trial was more satisfactory than
even on the last occasion, a brief report of which
appeared in The Sun. The usefulness of Mr.
White's invention for cleaning the bottoms of ships
when no means of docking are available seems to
be now placed beyond a doubt.
Her Majesty's ship Chesapeake sailed from Hong
Kong for England on the 22d May.
Vice-Admiral Sir J. Hope, K.C.8., had hoisted
his flag in the lmperieuse, and Rear-Admiral Jones
in the Chesapeake.
Capt. George 0. Willes had been appointed to
the Imperieuse, and Capt. Rochfort Maguire to the
Chesapeake.
Commander Robert Gibson had been appointed
to the Imperieuse, and Lieut. J. B. Butler had been
made Acting Commander of the Chesapeake.
The third dock at Chatham, now occupied by the
fine 51-gun frigate Arethusa, which is being con-
verted from a sailing ship to a screw steamer, is
ordered to be prepared for the reception of the mail-
clad iron steamer Defence, now building at Glas-
gow, which is to be forwarded to Chatham to be
fitted and made ready for sea. In order to complete
the Arethusa with the utmost despatch, and have
her ready to be undocked by the date ordered—the
9th of August—a large number of additional hands
have been placed on the work, the number of men
now employed being 300, including 60 caulkers. A
number of extra hands will be added this morning.
During the period the Arethusa has been in dock
she has been twice cut asunder to be lengthened,
and an addition of 58 feet 8 inches made to her
length amidships, and 14 feet aft. She has also
been considerably strengthened to adapt her for a
screw steamer. When completed she will be one
of the finest of the converted 51-gun screws. The
Arethusa is to be supplied with a pair of 500 horse
power (nominal) engines by Messrs. Penn and Son,
and the first portion of the machinery is now being
fixed on board. This frigate, as well as the Bom-
bay, 80, is to have the bottom covered with Muntz's
patent metal, in lieu of copper, the Admiralty hav-
ing decided on giving. that invention a fair trial.
The following appointments were made yesterday
at the Admiralty :—John Lee, chief engineer, to
the Indus for the Leopard ; Herbert W. Hart, act-
ing second-class assistant-engineer, to the Asia for
the Wallace ; James Radford, acting second-class
assistant-engineer, to the Cumberland for the Wild-
fire ; and Samuel Lloyd, acting second-class assist-
ant-engineer, to the Fisgard as supernumerary.
