A relic of Sir John Franklin's last expedition 1845-48. A seaman's certificate case owned by William Mark, Leading stoker HMS 'Erebus', from Hampstead, Middlesex aged 33 at the time of the expedition. It was obtained from the Inuit at Repulse Bay in 1854 by the Rae Expedition. The Inuit said that they had found the material at a camp to the north west of the mouth of the Back River where a party of Europeans had died of starvation. The case is a shallow rectangular shape, the lid is missing. It is stamped with the device of the Admiralty seal: a foul anchor surrounded by an oak leaf and surmounted by a crown with the latin inscription 'SIGIL . OFF I. MAG . ADM MAG .BR. &C.' 'WM' is scratched on the surface. It was presented to Greenwich Hospital by the Lords Commissioners of the Admiralty, 2 December 1854.
