THE NAVY.

or..

'1 'he experiments with the diving apparatus on
the plan suggested by Mr. White, surgeon, of
Fin chley, were resumed yesterday at Portsmouth
D 3okyard, in the presence of the officials of the
est a .blishment by order of the Commissioners of the
Adl- airalty. Mr. White's invention consists of ha
cyli, cider in lieu of the ordinary diving dress, and
of two vulcanized indiarubber tubes in lieu of an
air pump for the supply of air. The tubes are used
by Mr. White both with the customary diving dress
and helmet when the work to be done lies on the
grind, and with the cylinder when the latter is
used for cleaning the bottoms of iron ships. The

cylinder in use yesterday was roughly formed of
wood, and hooped with iron. It leaked so much
that it could be kept undei•water no length of time.

The cylinder is constructed of sufficient size to con-
tain a man, and with room enough to give play to
hid shoulders, his arms working free outside through
hates in the case fitted with vulcanized indiarubber
sleeves. These, however, can be readily dispensed
with if the operation to be performed is simply the
scraping of the vessel's bottom, a scraper being
fitted in front of the cylinder with its handle work-
; ing from the interior through an indiarubber valve.
The top of a cylinder is closed by a cap, in which
' are glass lights to enable the man to see his work,
and which is fastened by indiarubber springs and
hooks from the inside. A brass nut screws into the
centre of the cylinder cap through which pass two
indiarubber tubes for the supply of fresh air and
the discharge of the heated air from the cylinder.
The supply pipe is fitted with a mouthpiece. By
a simple contrivance it is fastened over the mouth
of the man inside the cylinder, who thus draws
each breath directly through the tube from
the surface of the water overhead. Each re-
spiration of the man under the ship's bottom
can be counted by those in charge of the tube
ends by the working of a slight valve at the
end of the supply tube, the stoppage of which
' will at once indicate that something is wrong below.
There are other means of safety. Through the two
tubes which supply the fresh and discharge the
heated air, conversation to any extent may be kept
up between the man at work below and those who
are in attendance upon him above, by which means
he also directs their movement of the cylinder to any
portion of the ship's bottom to which his work may
require him to go. In the event of any sudden and
unforeseen danger, when there is no time to commu-
nicate by speech through the tube, the man can cast
loose the springs of the cylinder cap, and throwing
it off, rise to the surface of the water in his inflated
india-rubber life-jacket. Although the trial was
necessarily short yesterday, owing to the leakage of
the cylinder, it was quite sufficient to prove the
soundness of the principle, and its adaptability, at
a wonderfully cheap rate, for cleansing the bottoms
of iron ships when afloat and without the means of
docking.
