Engraving showing Dr. Thomas Parke sucking poison from the side of Lieutenant Stairs during Sir Henry Morton Stanley's Emin Pasha Relief Expedition of 1887-1888. Lieutenant Stairs had been hit by a poisoned arrow which would probably have killed him, had it not been for Parke's prompt action to remove the toxin. Emin Pasha (1840-1892), the German doctor, explorer, linguist and Governor of the Egyptian Equatorial Province had retreated to Wadelai, near Lake Albert, with 10,000 followers during the Mahdi Rising of the mid-1880's. Cut off from all communication Emin Pasha was considered lost, so the British government sent out a rescue party led by H.M. Stanley (1841-1904).
