St. John's, Newfoundland, on the day before the
departure of the mail, Acting Captain J. F. Ross
having joined that ship at the latter port from the
Desperate, 7, in() horse power, Commander Thrupp.
The Cygnet, 5,80 horse power, Licut.-Commanuer
de Elan tzow, left St. John's, N. 8., on the Ist inst.,
for Forteau, Labrador. The Desperate, 7, took her
departure from St. John's, Newfoundland, on the
Ist inst., with Mr. Pesley and secretary on board,
who are on a tour of inspection of the fisheries.
The Cadmus was to leave Halifax for Bermuda,and
thence to Fort Monroe, on the 9th lest.
The model of the fixed cupola and armour-plated
ship, invented by Mi. Turner, master shipwright of
Woolwich dockyard,has been inspected and approved
by numbers of the leading private firms. Yesterday
some of the most eminent shipbuilders of Liverpool
waited on Mr. Turner with a desire of negotiating
permission to adopt his principle in ships
which
they are about to construct for the purposes of the
American war. The single cupola to befitted on the
deck of Mr. Turner's new ship will require no turn -
table or other machinery, and will contain 26 guns
capable of being fired at any required point or de-
flection, with sufficient space for free circulation of
the gunners. It is 220 ft. in length,loft. in depth,and
50ft. in breadth. The armour proof plates will be ap,
plied by a patent invention of Mr. Turnees,requiring
neither grooves nor tongues, and will be removable
singly in case of fracture or damage, and also easily
replaced. The Board of Admiralty, who inspected
the model on their visit to the dockyard a few days
ago, have called on Mr. Turner to furnish specifica-
tions of his method for their consideration. His
Royal Highness Prince Adalbert, Admiral of the
Prussian fleeL„ has also ordered draughts of the
model to be transmitted to him for the service of his
own country. The ship to be built after Mr. Turner's
design will carry 8,700 tons displacement burden,
and will be a most formidable ram, having a power-
ful weapon of Bft. in length projecting 3ft. under
the water line. Precautions are adopted to have her
rudder, stern post, and propeller thoroughly im-
mersed, and consequently out of tte reach of damage
from without.

A portion of the midships plating for the now 50
gun ship Caledonia, under construction in Woolwich
dockysrd, arrived yesterday from Mr. Brown, of
of 20 plates, weighing about
90 tons.
