 METEREOLOGICAL TABLE, 



ARRANGED FROM THE REGISTERS KEPT AT FORT RE- 

 LIANCE BY CAPTAIN BACK AND MR. KING. 



The following table exhibits the temperature of the 

 air and principal atmospherical phenomena observed at 

 Fort Reliance, from the commencement of November, 

 1833, to the end of May, 1834 ; and from the 22d of 

 October, 1834, to the 18th of March, 1835. 



The temperatures were registered fifteen times in the 

 twenty-four hours, between six o'clock in the morning 

 and midnight. The daily means were obtained from 

 the fifteen observations. The four thermometers which 

 were used were coloured spirit ones, made by Newman, 

 and were hung up on the north side of the observatory 

 where they were registered ; but finding that they varied 

 from each other as the temperature decreased, and that 

 one gave nearly the mean of the whole, it was after- 

 wards used as the standard thermometer, and from it 

 the observations were made. 



The remarks made on preceding voyages regarding 

 the generally calm state of the atmosphere during in- 

 tense cold are in a great measure corroborated by the 

 following table, though iu some few instances it will 

 be seen that a very low degree of the thermomelei was 

 accompanied by a breeze preceding or immediately fol- 



lowing a calm.
