Arctic Expedition.

tion of the discovery of a north-west passage, two ships, the Erebus and Terror,

means of security and comfort, but with a means of applying the power of steam

in Europe and America, wherever magnetic observation is at the time in 
progress. Among the instruments with which this Expedition is provided,
