Low-tension Electric Fuses.—Consisting of a case of glass or other suitable material, containing two insulated wires, the terminals of which are connected by a bridge of platinum wire or other suitable material, imbedded in a charge not exceeding 20 grains of (a) gunpowder, or (b) carefully purified collodion cotton, or (c) carefully purified gun-cotton, or (d) chlorate of potash and sulphide of antimony.—(No. 3 Definition.)

Low-tension Electric Fuses.—Consisting of a case of wood or other suitable material, containing two insulated wires, the terminals of which are connected by a bridge of fine wire, the said bridge being imbedded in a charge not exceeding 2 grains of a priming composition consisting of chlorate of potash, sulphide of antimony, and plumbago.—(No. 4 Definition.)

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.)

Spon’s Electric Fuses.—Consisting of a case of metal, wood, paper, or other suitable material, containing two or more insulated wires, the terminals of which are (a) imbedded in a charge not exceeding 5 grains of one or the other of the priming compositions (1), (2), (3), hereinafter specified; or (b) connected by a bridge of fine wire composed of a platinum alloy, steel, or other suitable material, the said bridge being imbedded in a charge not exceeding 10 grains of one or other of the priming compositions (4), (5), hereinafter mentioned:—

Priming Composition (1).—Chlorate of potash and sulphide of antimony, with or without powdered carbon.

Priming Composition (2).—Chlorate of potash, sulphide of antimony, and phosphide of copper.

Priming Composition (3).—Chlorate of potash, sulphide of copper, and phosphide of copper.

Priming Composition (4).—Gun-cotton thoroughly purified.

Priming Composition (5).—Gun-cotton thoroughly purified, chlorate of potash, and powdered galls.

Elswick Electric Tubes.—Consisting of a case of metal, wood, paper, or other suitable material, containing (a) two or more insulated wires, the terminals of which are connected by a fine wire of platinum or other suitable material, imbedded in a charge not exceeding 10 grains of gun-cotton thoroughly purified, and (b) a charge not exceeding 1 oz. of gunpowder, the said case being completely closed by means of a cork, disc, or other suitable material.

Fuses for Shells.—Consisting of cases of wood, metal, or other suitable material, charged or primed with fuse or other suitable composition not containing their own means of ignition, and of such strength and construction that the explosion of one fuse will not communicate the explosion to other like fuses.

German Spills.—Consisting of cylindrical cases of paper, containing a charge of gunpowder not exceeding 1 lb. per gross, and primed at one end with touch-paper, and at the other with mealed gunpowder, or primed at both ends with mealed gunpowder.

Gunpowder Fuses.—Consisting of cases of metal, wood, or other suitable material, containing a charge of gunpowder not exceeding 2 drams in each fuse.

Gun-cotton Fuses.—Consisting of cases of metal, wood, or other suitable material, containing a charge of thoroughly purified gun-cotton not exceeding 2 drams in each fuse.

Instantaneous Fuses.—Consisting of a preparation of gunpowder, yarn, and a protective coating, which is not a safety fuse, and does not contain its own means of ignition.

Miner’s Squibs.—Consisting of a tube of paper or other suitable material, partly filled with gunpowder in the proportion of not more than 1 lb. of gunpowder to every 500 squibs, and having one end closed with a plug of wax or other suitable material, and the other end closed by being twisted, and such twisted end being coated with sulphur, or not so coated.

Pain’s Instantaneous Pyrotechnic Fuses.—Consisting of a closed case of paper, wood, or other suitable material, having affixed therein, by means of a plug of sulphur, two insulated copper wires, the terminals of which are connected by a bridge of fine wire, consisting of platinum, platinum alloy, steel, or other suitable material; such bridge being imbedded in a charge of gunpowder not exceeding 20 grains.

Tubes for Firing Explosives.—Consisting of cases of quill, metal, or paper charged with mealed powder or other suitable explosive, and not containing their own means of ignition.

War-rockets.—Consisting of cases of iron or other suitable material, containing rocket composition, consisting of an intimate mixture of saltpetre, sulphur, and charcoal, and not containing their own means of ignition.

Division 3.

(Containing their own means of ignition.)

Abel’s Electric Detonator Fuses.—Consisting of a case of wood or other suitable material, containing two insulated wires, the terminals of which are (a) imbedded in a charge not exceeding 2 grains of the priming composition No. 1 (hereinafter specified), or (b) connected by a bridge of fine wire composed of a platinum alloy, steel, or other suitable material, the said bridge being imbedded in a charge not exceeding 10 grains of the priming material No. 2, hereinafter specified, the case being fitted with a detonator.

Priming Composition No. 1.—Consisting of sulphide of copper, phosphide of copper, and chlorate of potash intimately mixed together.

Priming Composition No. 2.—Consisting of gunpowder and thoroughly purified gun-cotton.

Bornhardt’s Electric Detonator Fuses.—Consisting of a detonator as defined hereinafter, such detonator having inserted therein two insulated wires, the terminals of which are imbedded in a priming composition composed of chlorate of potash and native sulphide of antimony, and the detonator being so constructed and the wires so adjusted and secured that the terminals of the said wires cannot come into contact with the fulminate in the said detonators.

Brain’s Electric Detonator Fuses.—Consisting of Brain’s electric fuses, as hereinbefore described (see Division 2), and having attached thereto a detonator as hereinafter defined.

Cartridges for Small Arms (which are not safety cartridges).

Colliery Safety Lighters.—Consisting of a tube of metal, mill-board, 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 potassium 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
