The early part of this month was remarkably fine and mild, being 

 distinguished by very high readings of the Barometer. On the 8th, at 

 6 a.m., the reading was 30°^552, being the highest on record, and the 

 mean for that whole day 30°^3942, is also the highest recorded. A 

 great depression succeeded, reaching its lowest point between the 21st 

 and 22ad, from -which period the character of the weather changed to 



cold and stormy, with downfalls of snow, high winds prevailing for the 

 next 14 days, and giving a mean velocity for that period of 11^48 miles 

 per hour. 



The monthly range of the Barometer (1^835 inches) is tie greatest 

 recorded : the temperature on the whole is 1°^6 above the average ; 

 and the fall of rain is 1^176 inches less, and that of snow 9^9 inches 

 more than the mean of 15 years.
