NORTHERN EXPEDITION. 
Oficial accounts have arrived from the vessels employed in the 
attempt to discover the North-west passage to the Pacific Océan, 
dated July 28th and August Ist. At the date of the first, de- 
spatches the Isabella and the Alexander were in latitude 75° 30° 
N. longitude 60° 30’ W. very near the head of Baffin’s Bay. The 
Weather was serene and perfectly clear. The variation of the 
* compass, by accurate observations repeatedly made on board 
both ships, was 89° and the dip 84° 30’. It had been perfectly 
calm, and the sea as smooth as glass for three or four days, and’ 
the current drifted them to the south-eastward, which raised their 
hopes of there-being an open passage to the westward, through 
Alderman Jones’s or Sir James Lancaster’s Sound. All the way 
up the middle of Davis’s Straits they skirted an unbroken field 
of ice on the left, but as they proceeded it became thinner, and 
apparently rotten, and they were sanguine that, the moment the - 
breeze sprang up, the ice to the westward would allow them to 
reach the northern shores of America. The utmost harmony
