Some interesting experiments have been made at Chat-
ham in the presence of the officers of the Royal Engi-
ne:re, under the sanction of the Secretary of State for
War, for the purpose of testing the merits of an iuyention
submitted to Lord Panmure, which, it was considered,
would have the effect of giving an increased effect to the
charges of gunpowder used in the sapping and mining
operations carried on by the men of the Royal Engineers
at Chatham. A strong box was proposed to be made
capable of containing a charge of 151 b. weight of gut-
powder ; one side of this bc-x, which was allowed to re-
main open, was placed in the ordinary manner a „!ainst
large beam of timber, intended to represent a stockade.
On the charge bring ignited by means of the voltaic bat-
tery, the beam was blown to a distance of 15 feet. • An-
other box was then made; "to contain the same weight of
gunpowder, but firmly closed on all sides ; the effect of
the explosion in this- instance was to send the balk of
timber a few inches over 15 feet. A third experiment
was then made with a box of the same size, and filled
with the same weight of gunpowder used for the former
charges, but in this instance a portion of the box was
covered with sandbags, placed at the sides, for the pur-
pose of acting as a resistance to the gunpowder in that
direction, the principle being the same As that hitherto
adopted in the Royal 'Engineers. On the powder
being fired the charge blew the beam of timber to
the distance of 50 feet, thus proving the superiority of
tfie methods practised by the Sappers and Miners. The
results of the experiments were considered very satb:-
faetory to the Engineer officer.
The launch of the Renown, 91, will take place at Chat-
ham on Saturday afternoon next.

Her Majesty's ship Niger, Captain the Hon. A. A.
Cochrane, on tt.e 13th of November was the flagship of
the Admiral Commander-in-Chief, Sir M. Seymour, at
Canton, where she had roently arrived from Singapore
pia L.Abuan and Manila. .On her passage to Cat t rhe-
was struck by e, sudden squall off the eoast of Borneo,
which carried away her mainmast.

The Duke of Wellington, 131, Captain Caldwell, C. 8.,
fi g of Rear-Admiral Sir Richard Saunders Dundas,

Nimrod, '6, ecrew despatch gun vessel, Commander
Roderick Dew, armed with two 63-pounders and four
short 32-pounders (little better, than carronades), will be
ready for sea by Wednesday next, and await her final
'instructions before leaving for China. It is to be re-
gretted that she is not furnished with two additional 68-
pounders instead of the useless 32's ; a couple or f..ur
brass 24-pounders-or bras howitzers would answer all
purposes for close quarter , and be also available for
shore service.

Terror, 14, floating battery, returned to Sheerness
from her late trial trip on Saturday, about 10 a.m., and
atehored at the dockyard moorings. Captain .Edward
Percy Halted, of the steam reserve, wiih Mr. J. H.
Langley, inspector of machinery afloat, and Mr. Enwood,
foreman shipwright afloat, accompanied her; we hear
the tent: upon the. whole was moat satisfactory, and they
got about fiv,:t knots an hour out of her in spite of the
boisterous state me the weather; her steering qualities
have also proved far hei:.!er than could be expected, con-
sidering her build and eubsec uent dead water in which
the rudder has to act ; but she V91..1 make another trial
when the weather is more propitious to ascertain her
precise speed. She ran in a gale of wind irt:.m the east-
ward, and appeared more buoyant than eoult: be ex-
pected, considering her enormous weight.

tions, but without obtaining a cure. By the blessing of
God and using only three pots of Poor Man's Friend,
and taking three boxes of pills, she was perfectly cured.
