Meteorological Observations for February 1827. 319 



On the 16th the thermometer receded 18 degrees below the freezing^ 

 point, and the night was the coldest we have had here since the 15th of 

 January 1820, when the same degree of cold was registered. The viinimum 

 temperature of the external air at Paris in the nights of the 17th and 18th 

 instant, was four degrees of Fahrenheit's scale lower than it was here on 

 the 16th, Paris being about 110 miles inland from the nearest sea-shore of 

 the British Channel. 



This depression of temperature, though it came on rather late, was very 

 seasonable, as it will prove beneficial to cultivated lands, and in a great 

 measure preserve the corn and vegetation, in consequence of the destruction 

 of ground insects, which for the last two or three years had increased and 

 made such ravages thereon. The thaw was so slow and gradual from the 

 21st to the 25th, as to be almost imperceptible ; but on the 27th the ther- 

 mometer rose to 56 degrees, with a South-west gale and a humid air. 



The mean temperature of the external air this month, is 2-3-1 Oths de- 

 grees colder than that of January, and 5-1-lOth degrees colder than the 

 mean of February for the last eleven years. 



The atmospheric and meteoric pfi(enoniena that have come within our 

 observations this month, are one Aurora Borealis, four solar halos, four 

 meteors, and ten gales of wind, or days on which they have prevailed, viz. 

 six from the NE., one from E., and three from the S.W.
