Abstract : In 1770, Lieutenant James Cook, on his Australian voyage of discovery, was forced to jettison six cast-iron cannon off the Great Barrier Reef. The guns, two of them loaded, were recovered two years ago and restored. The author describes the process of cleaning and preserving the guns, and the analysis of their chemical composition. He also discusses historical aspects, including the evidence which suggests the names of the gunfounders who made the cannon. (Author)
