copper wire. This done the electrical circuit is com-
pleted, the alarm bell in the captain's cabin is rung,
and a flap on the dial plate flying up exhibits a
number which gives the exact portion of the ship's
hold in which the extra heat is generating. The
part in the Nlersey's hold selected to test the prin-
ciple on Saturday was the handing room of the
after magazine, the calorimeters there being fixed in
the beams, and their " temperature distance," if the
space between the ends of the copper wire and the
surface of the mercury may be so called, fixed at
154 degrees. Fires were lit is stoves in the hand-
ing room, and its temperature increased by these
means to 175 degrees, when the calorimeters acted
and transmitted the signal to the alarm bell and the
dial plate in the captain's cabin in a most unmis-
takable manner. The trial was considered most
satisfactory.

The paying out of commission of the crew of her
Majesty's late ship Amazon took place on board the
Duke of Wellington, Capt. C. Fellowes, at Ports-
mouth on Thursday. Commander Hunter, the late
Commander of the .tmazon, read a letter to his
officers and ship's company, previous to their pay-
ment, from Vice-Admiral Sir Thomas Pasley, Port-
Admiral and Commander-in-Chief at Portsmouth,
in which the gallant Admiral stated that he was
directed by the Lords Commissioners of the Admi-
ralty to express the great satisfaction of their lord-
ships with the conduct of the officers and crew of
the Amazon after the collision of that ship with the
late steamship Osprey, although their lordships
could not but regret the results of the collision.
Her Majesty's 6-gun paddle sloop Devastation,
Commander Wm. K. Jolliffe, ordered home from the
Pacific at the commencement of the present year,
arrived alongside the powder buoy of the Royal
Arsenal at Woolwich yesterday, and having dis-
charged her guns, powder, and other war stores,
she went up to the dockyard, in preparation to be
dismantled and paid off for repairs. Three of the
officers only, who joined on her being commissioned
on the 9th of December, 1861, have remained dur-
ing the term of commission, namely :—Lieut. Shat-
tock, Francis 0. Simpson, master ; and William
Carter, assist.-paymaster. After being stripped the
Devastation will be placed in the third division of
the Woolwich steam reserve.

The following district order relating to the 31st
Regiment, the head-quarters of which left Ports-
mouth on Sunday for Ireland, and will be followed
by the remainder of the regiment on Thursday, has
been promulgated in Portsmouth garrison :—" Ad-
jutant-General's-office, -.Portsmouth, District Order.
The 31st Regiment being about to embark for Ire-
land, the Lieut.-General cannot permit it to quit the
South-West District without expressing to Colonel
Eagar the officers, non-commissioned officers, and
men under his command, his regret at losing the
services of so good a corps. The appearance of the
regiment on parade, the steadiness and quickness of
its drill, its good discipline in quartp, and its gene-
ral efficiency on all occasions leave nothing to be
desired. By order, A. ALISON, Lieut.-Col. and
A. A. Adjt.-Gen."
