abstract:HMS Discovery was a wooden screw storeship, formerly the whaling ship Bloodhound. She was purchased in 1874 for the British Arctic Expedition of 1875–1876 and was sold in 1902.
The preservation workers from New York's Central Park Conservancy were removing rust from the antique cannon, which once fired munitions aboard the British warship HMS Hussar, when they made the explosive discovery, New York police Detective Brian Sessa said.
