The greatest height of the barometer was 30.86 on the 26th April. 
The lowest state of ditto, - 29.00 on the 6th March. 
These results indicate a very extraordinary degree of cold at 
Melville Island. According to the Table given by Mr Leslie, 
after Mayer and Kirwan, the temperature of Melville Island 
should have been nearly 36°, whereas it is only 1 J°, a result which 
throws into the shade all those speculations respecting the cli- 
mate of the Arctic Regions with which the public have been so 
long misled. Nor can this difference between hypothesis and 
observation be ascribed to any accidental or local cause. The 
same singular distribution of heat on both sides of Baffin’s Bay, 
is deducible from numerous observations made on the coast of 
Greenland b^ Sir Charles Giesecke and the Danish Governors, 
extending over a period of nearly seven years. The following are 
the results which we have deduced from these Tables, (which have 
been kindly communicated to us by Sir Charles Giesecke), con- 
trasted with those of the hypothetical table already mentioned :
