Remarks. 



L great depression of temperature took place in this month, 



| the mean being nearly 6° below the average. The wind s 



! from north-east on the 24th of last month, and continued al 

 constantly in the same direction till the 18th of the present 

 I unusually cold month appears to have been the consequ 



Frosts set in as early as the 1st; and twelve frosty nights were 

 ! indicated by the common thermometer, and twenty by the radi- 

 ating one. On the night of the 21st the frost was n 

 severe for the period of the season, the thermometer being 12 

 below the freezing point, whilst the radiating thermometer sunk 

 to 12 or 20 below freezing. The beauty of the Dahlias and 

 other similarly tender flowers was then of course completely 

 spoiled for the season. No rain fell till the 18th, the barometer 

 standing high ; but the wind then became variable tor a few days, 

 and afterwards set in from the south-west, when the barometer 

 fell exceedingly, and was remarkably low on the 23rd, about 

 which time rain fell heavily.
