General Observations. — The first part of this month to the 8th was mild 

 and mostly wet, the latter part was rather cold and remarkably dry — as 

 heavy rains and floods, in accordance with the old adage, generally happen 

 in February. The month, like the preceding one, passed off without frosty 

 weather, the external thermometer having only receded twice to the 

 freezing point. Hoar frost appeared several mornings before sunrise, but 

 scarcely any ice, and no snow; nor did any atmospheric phaenomena pre- 

 sent themselves. 



From the dryness of the period the mean barometrical pressure is com- 

 paratively high, and the mean temperature of the external air nearly coin- 

 cides with the mean of February for a series of years. Much low haze 

 appeared on eleven days while the sky was overcast. The maximum tem- 

 perature for the twentj-four hours occurred in the night of the 3rd, which 

 was followed by rain. On the 16th the vane revolved round the compass 

 several times, — a circumstance that rarely happens, and which was also 

 succeeded by rain. 



On the 23rd, 24th, and 25th, the fog was so thick here, particularly in 

 the mornings, that it was unsafe to attempt crossing the ferry. Business 

 was much retarded in London, and on the Thames j and several persons 

 who had lost their way, were drowned. 



Only three gales have occurred this month, viz. two from the North- 

 east, and one from the South-east.
