needle from Cumberland House, we ascer- 

 tained the dip to be 85° 23' 42", and the dif-

 Several observations had been procured on 

 both sides of the moon during our residence 

 at Fort Chipewyan, the result of which 

 gave for its longitude 111° 18' 20" W., its 

 latitude was observed to be 58° 42' 38" N., 

 and the variation of the compass 22° 49' 32" 

 E. Fresh rates were procured for the 

 chronometers and their errors determined 

 for Greenwich time, by which the survey 

 to the northward was carried on.
