MILNER'S SAFETY BOXES.
RECENT events have awakened so general a feeling of
the momentous importance of securing protection from
fire to Deeds, Records, M.SS., Books and Papers of Ac-
compt, Cash, Gunpowder, and all combustible materials,
that THOS. MILNER and SON feel excused in again in-
viting public notice to their Patent Fire-resisting Deposito-
ries. Having submitted their one-chambered Boxes, of one
inch in thickness, to severe trials in the principal towns, they
have received from the authorities of each the most satisfac-
tory certificates of their efficiency for ordinary casualties;
and being confirmed in opinion by a long course of experi-
ment, that, under suitable modification of chambers and
thickness of boxes, the peculiar principle of their Patent is
capable of affording security under the severest ordeal likely
to occur in calamities of the kind, they respectfully solicit
the consideration of Gentlemen interested in mechanical
science to the subject generally, and investigation into the
pretensions of the various means of security in use, their
own amongst the rest.
M. and S. are prepared to submit their manufactures to
public trial with any others of equal dimensions, whilst their
comparatively moderate cost renders them extensively avail-
able. _ _

The certificate of the satisfactory trial of their Boxes in
Liverpool bears the signatures of the following Gentlemen,
to whom permission of reference is kindly given,—
THOMAS BOLTON. Esq., (ex-Mayor,)
JOHN SHAW LEIGH, Esq., (the Mayor,)
Sir THOMAS BRANCKER,
BARTHOLOMEW PRESCOT, Esq.,
L. GRAHAM, Esq.,
R. FRODSHAM, Esq.,
WM. STOCK, Esq•.
S. WOODS, jun., Esq.
The more recent one below will be interesting to Ship-
owners and Builders, Gunpowder-dealers, &c., and is further
confirmatory of the capabilities of the principle :
Trial of Milner's Patent Fire-Resisting Principle, as a
Protection of Gunpowder from Fire.
Liverpool, June 20th, 1842.
We have this day witnessed the trial of one of Milner's
Patent Fire-proof Double-celled Gunpowder Magazines, of
twelve inches external, and six inches internal diameter and
height, filled with highly combustible materials, papers, and
a packet of Gunpowder.
The same was placed in the centre of a fire consisting of
five to six cwt. of coal and a quantity of wood, and remained
therein upwards of three hours, during two-thirds of which
time the magazine was surrounded by a complete furnace of
intense heat. . .

Neither the inner magazine nor its contents were at all
injured by the fire, nor did they evince any signs of the se-
vere ordeal to which they had been exposed, beyond being
pervaded to the very centre with steam from the alkaline
solution, contained in tubes embedded in the nonconductor
occupying the chamber of each cell.
In proof of the intense heat of the fire, the wood was
wholly consumed, the entire quantity of coal converted into
coke, and the bricks upon which the fire was made were
taken out red hot. .
