66. On the word “March,” the combatants may advance in a zigzag step, not exceeding two paces. They may take aim without firing; and while advancing stop when they choose, and advance again; but once having fired, both parties must halt on the spot.
67. The combatant who has not fired, may now fire, but without advancing; and the party who has fired, must firmly stand the fire of his antagonist, who for that purpose is allowed half a minute; if he allows a longer time to elapse, he must be disarmed by the seconds.
68. In the pistol duel, called à ligne parallèle, two parallel lines are traced by the seconds fifteen paces from each other, and from thirty-five to twenty-five paces in length.
69. The combatants are placed at the extremity of each line, fronting each other.
70. The seconds stand behind their principals in a situation that may not expose them to the fire of the parties. The signal is given by the word “March.”
71. The combatants then advance, not upon each other, but in the direction of the line that has been traced for them; and, therefore, whether one of the adversaries has advanced or not, he will, find himself placed at fifteen paces from the other.
72. The champion who fires must stop; but he may halt without firing, take aim, and continue to advance.
73. In the pistol duel called au signal, the signal is to be given by the second of the offended party by three claps on the hand, three seconds being counted between each clap, which will take up nine seconds; or two seconds, which will take up six seconds. In other cases, the seconds draw lots for giving the signal.
74. The combatants, when they have received their arms, are to walk, but keep the muzzles of the pistols pointing to the ground; at the first signal they will raise their arms, take aim at the second signal, and fire simultaneously at the third.
75. If one of the combatants fires before the third signal, or half a second after it, he is to be considered as a dishonourable man, and, if his antagonist is killed, an assassin; and if he fires before the signal without effect, his opponent has a right to take as much time as he thinks proper to level at him and shoot him.
