January. — Till the 7tli the air was cold, being 3°-2 below the 

 average ; then warm until the 20th, the average excess being 4°'7 ; 

 again cold till the 27th, the deficiency being daily 4°-2 from the 

 average ; and from the 28th to the end of the month warm, being 

 4° -7 in excess. The mean temperature of the month differed little 

 from the average. 



February was cold nearly throughout, excepting on the 3rd, 4th, 

 Tith, Gth, and 13th, when the temperature was somewhat in excess. 

 The mean temperature of the month was nearly 4° below the 

 average. 



March till the 12th was cold, the daily deficiency being 8° ; from 

 the 13th to the end it was warm, the temperature averaging .5" "3 in 

 excess. This month was nearly of its average temperature. 



Tlie greatest differences in the temperature of the air occun-edin 

 the Midland counties. 



The mean degree of humidity, and the mean temperature of the 

 dew-point, were less than the average value in each month, and in 

 all cases to greater amounts than the deficiency of temj)erature : 

 therefore the air was less humid than usual. 



The reading of the Barometer was nearly half an inch in excess 

 of the average in the month of January ; in Febraary slightly above 

 the average ; and in March a little in defect. 



The fall of rain in January and March was deficient, and in 

 February in excess of the average ; it was nearlj- half an inch in 

 defect on the quarter. 



During the three months there was almost a total absence of 

 thunder and lightning. 



The mean temperature of the air at Greenwich for the quarter 

 ending Febniary, constituting the three winter months, was 39"^, 

 being 1°'3 above the average of 87 years.
