December. — During December most of the meteorological 

 elements approximated closely to their normals, the most 

 noticeable feature being the dense fogs which accompanied 

 the cold weather from the 18th to the 25th. The maximum 

 barometric pressure for the year occurred on the 21st, and 

 was soon followed by the minimum for the year, on the 30th. 

 Although little sunshine was recorded, there were never 

 more than three consecutive days without any. Snow fell 

 on the 1st and 8th, but the month, as a whole, was mild and 

 open, presenting little appearance of winter. The wind blew 

 almost wholly from the west and south-west.
