Captain Nemo's Underwater Electric Pellet Gun
One of the Nautilus's men presented me with a streamlined rifle whose butt was boilerplate steel, hollow inside, and of fairly large dimensions. This served as a tank for the compressed air, which a trigger–operated valve could release into the metal chamber. In a groove where the butt was heaviest, a cartridge clip held some twenty electric bullets that, by means of a spring, automatically took their places in the barrel of the rifle. As soon as one shot had been fired, another was ready to go off.
These versatile guns are charged from portable compressed air tanks but instead of shooting conventional solid bullets, they launch small glass capsules…,which are sheathed in steel and weighted with lead. They are veritable little Leyden jars charged with high-voltage electricity. At the slightest impact they discharge, and the animal, no matter how large or strong, falls dead. -- 20,000 Leagues Under the Sea by Jules Verne
