This is made by dissolving gun-cotton in ether with alcohol, and adding some iodide of ammonium. When a thin layer of this fluid is poured on the glass plate, the ether and alcohol evaporate very speedily, and leave a closely adherent film of organic matter derived from the cotton, and containing the iodide of ammonium.
"It's this gun-cotton that begins to make our calling in life look like a really dangerous one," muttered Jack, as he produced the key and fitted it into the lock. "Once upon a time," murmured Hal, "we thought there was sufficient danger, just in going out on the ocean in a submarine torpedo craft, and diving below the surface."
Conditions may be arranged so that an explosive remains unchanged wet gun-cotton is not exploded by a shock which would start the explosion of dry gun-cotton in other words, the explosion of an explosive can be regulated: the explosive changes of a radio-active substance, which are accompanied by the radiation of energy, cannot be regulated; they proceed spontaneously in a regular and definable manner which is not influenced by any external conditions such as great change of temperature, presence or absence of other substances so far as these conditions have been made the subject of experiment: the amount of activity of a radio-active substance has not been increased or diminished by any process to which the substance has been subjected.
She also mounted on the after-deck two 18-inch torpedo tubes, firing Whiteheads of an effective range of eight hundred yards at a speed of thirty knots, and carrying a charge of one hundred and seventy-one pounds of gun-cotton enough to destroy a battleship, if it happened to hit the right spot.
He went farther, and said to himself, "If these really are the things that give rise to the appearance of spontaneous generation, I ought to be able to take a ball of this 'dusted' gun-cotton and put it into one of my vessels, containing that boiled infusion which has been kept away from the air, and in which no infusoria are at present developed, and then, if I am right, the introduction of this gun-cotton will give rise to organisms."
In vain had he forbidden entrance to Stony Hill; every day curious sightseers climbed over the palisading, and some, pushing imprudence to folly, came and smoked amongst the bales of gun-cotton. Barbicane put himself into daily rages.
He was going to add, "It contains carbon, hydrogen, nitrogen, and oxygen, corresponding to " when my mother stopped him. "Dear me, Mr Firebrand, is a popular explanation impossible?" "Not impossible, madam, but rather difficult. Let me see. Gun-cotton is a chemical compound of the elements which I have just named a chemical compound, you will observe, not a mechanical mixture, like gunpowder.
"I wonder how that got through the custom house?" was Eph Somers's next undertoned question. "Ah, good morning, gentlemen," greeted the stranger, coming toward them, all smiles and bows. "Av I have not med ze mistake, zen I am address ze torpedo boys." "Right-o," drawled Eph. "Regular human torpedoes, as touchy as gun-cotton. Why, I am due to explode this moment!"
At last, there being a Providence even for artillerymen, nothing blew up, and the loading was happily terminated. The third bet of Captain Nicholl was therefore much imperilled. There still remained the work of introducing the projectile into the Columbiad and placing it on the thick bed of gun-cotton.
It appears that after the first few of us had gone down the cliff, and the rest were preparing to follow, a bullet struck some cakes of gun-cotton lying on the ground by the head of the path, where they had been placed while the Sappers were at work.
