during the Expedition under Captain Parry. 197 
1. Magnetical Observations. 
As the measures of the variation and dip of the needle could be 
taken only on icebergs and islands, out of the reach of the ship’s 
attraction, they are not so numerous as might have been expect- 
ed ; but they make up in importance for what they want in 
quantity, and will be studied with much interest by the philo- 
sophers of all countries. The following Table contains the 
whole of the results given in Captain Parry’s work, and deduced 
from observations made principally by Captain Sabine *.
