CLASS 4.—CHLORATE-MIXTURE.

Division 1.

Nil.

Division 2.

Nil.

CLASS 5.—FULMINATE.

FULMINATE.—The term “fulminate” means any che-
mical compound or mechanical mixture, whether included
in the foregoing classes or not, which from its great sus-
ceptibility to detonation is suitable for employment in per-
cussion-caps or any other appliances for developing detonation,
or which, from its extreme sensibility to explosion, and
from its great instability (that is to say, readiness to undergo
decomposition from very slight exciting causes), is especially
dangerous.

This class consists of two divisions.

Division 1 comprises such compounds as the fulminates
of silver and of mercury, and preparations of these sub-
stances, such as are used in percussion-caps, and any pre-
paration consisting of a mixture of a chlorate with phos-
phorus or certain descriptions of phosphorus-compounds,
with or without the addition of carbonaceous matter, and
any preparation consisting of a mixture of a chlorate with
sulphur, or with a sulphuret, with or without carbonaceous
matter.

Division 2 comprises such substances as the chloride
and the iodide of nitrogen, fulminating gold and silver, dia-
zobenzol, and the nitrate of diazobenzol.

CAP-COMPOSITION.—Consisting of chlorate of potash and
sulphide of antimony or sulphur, with or without fulminate
of mercury and ground glass.

CLASS 6.—AMMUNITION.

Division 1.

PERCUSSION-CAPS.—A percussion-cap does not include a
detonator. Percussion-caps shall be protected with tinfoil,
and shall be imported without anvils.

RAILWAY FOG-SIGNALS.—Of such strength and construc-
tion, and containing an explosive in such quantity, that the
explosion of one such railway fog-signal will not communi-
cate the explosion to other like railway fog-signals.

SAFETY CARTRIDGES.—Consisting of cartridges for small-
arms, of which the case can be extracted from the small-arm
after firing, and which are so closed as to prevent any ex-
plosion in one cartridge being communicated to other cart-
ridges.

SAFETY FUSE.—Consisting of a fuse for blasting which
burns and does not explode, and which does not contain its
own means of ignition, and which is of such strength and
construction and contains an explosive in such quantity
that the burning of such fuse will not communicate laterally
with other like fuses.

TUBE SAFETY FUSE.—Consisting of a pipe or tube of
pewter, coated externally with tarred yarns, tapes, or other
suitable covering, and containing gunpowder in the pro-
portion of not more than 1½ oz. to every 24 ft. of fuse.

SAFETY FIRING-TUBES No. 1.—Consisting of a tube of
metal or other suitable material, containing a percussion-
cap and suitable mechanical appliances for firing the same.

Division 2.

(Not containing their own means of ignition.)

CARTRIDGES FOR SMALL-ARMS (which are not safety car-
tridges).

LOW-TENSION FUSES. — Consisting of a case of copper,
wood, or other suitable material, containing two insulated
wires, the terminals of which are connected by a bridge of fine
wire of platinum or other suitable material, imbedded in a
mixture of chlorate of potash, native sulphide of antimony,
and fulminate of mercury, not exceeding in all 5 grains,
and the fulminate of mercury not exceeding one-tenth of
the whole.—(No. 5 Definition.)

Division 3.

(Containing their own means of ignition.)

CARTRIDGES FOR SMALL-ARMS (which are not safety car-
tridges).

COLLIERY SAFETY LIGHTERS.—Consisting of a tube of metal,
millboard, or other suitable material, closed at one end, and
containing sulphuric acid enclosed in a glass globule or tube
imbedded in or contiguous to a mixture of chlorate of potas-
sium and sugar (whether or not contained in an inner metallic
tube containing or not containing gunpowder), and with or
without the addition of a piece of safety fuse: Provided that
the amount of the mixture aforesaid contained in any one of
the said colliery safety lighters shall not exceed 5 grains:
Provided also that the said colliery safety lighters shall be
of such strength and construction that the ignition of one
such colliery safety lighter will not communicate laterally with
others.

DETONATORS.—Consisting of a capsule or case of such
strength and construction, and containing an explosive of
the fulminate class in such quantity, that the explosion of
one capsule or case will not communicate the explosion to
other like capsules or cases.

CLASS 7.—FIREWORKS.

Division 1.

FIREWORK COMPOSITION.—Consisting of any chemical com-
pound or mechanically mixed preparation of an explosive or
inflammable nature which is used for the purpose of making
