328 ACCOUNT OF THE ARCTIC REGIONS. 



From the circumstance of the thermometer and 

 the barometer frequently suffering great and rapid 

 simultaneous changes, the thermometer becomes a 

 valuable appendage in assisting in the prognosti- 

 cation of the weather. Thus, when the thermome- 

 ter rises with a falling barometer, a storm may be 

 expected from the south. When the barometer 

 rises and the thermometer falls, during a southerly 

 storm, the return of fine weather is indicated, with 

 a change of wind towards the north. When the 

 barometer falls, together with the thermometer, du- 

 ring a southerly or easterly breeze, a northerly or 

 westerly wind may be expected, but not of great 

 intensity, unless the fall of the barometer be very 

 considerable. 



The great depression of temperature which takes 

 place in the proximity of ice with a northerly wind, 

 appears equally as considerable to the feelings in 

 low as in high latitudes. Thus the ice, when ac- 

 cumulated into a connected body, extending, ap- 

 parently, from the place of observation to the Pole, 

 causes an equalization of temperature between the 

 two situations, so that whatever may be the lati- 

 tude, it is probable, that the cold under a strong- 

 north erly gale, will be very nearly as intense as at 

 the Pole. In confirmation of this, I may re- 

 mark, that as great a degree of cold as ever I no- 

 ticed, in a series of twelve years' observations, (once
