fell in the City on the 25th, and again on the 26th, and the 

 atmosphere became keener and more seasonable. 



The atmospheric pressure for the first part of the month was 

 moderate, but during the second part there were some sharp 

 changes. The highest reading of the month occurred during 

 the latter part — 30*20 inches on the 23rd — and the lowest, 28*80 

 inches, on the 27th. 



Frost was registered on nine days, and amounted to 25° in 

 all. The lowest reading was taken on the 29th, when 7° of 

 frost were recorded. The average maximum temperature for 

 the month was 42°, and the average minimum 34°, as compared 

 with 43° and 35° respectively for the same month of 1900, when 

 12° of frost for five mornings were recorded. 



The month's rainfall was moderate, and amounted to 2*68 

 inches, which included a good proportion of melted snow. The 

 greatest daily rainfall was 0*46 inches, on the 19th. 



The comparatively dry nature of the weather was much in 

 favour of vegetation generally, which had already become sur- 

 charged with moisture with the heavy rains of the preceding 

 months, and the colder weather checked the flow of sap in trees 

 and shrubs. Snowdrops and narcissi in the open borders were 

 well above the ground at the close of the month. 



February. — The cold and seasonable weather of the latter part 

 of January continued into this month, the atmospheric conditions 

 being keen and bracing. On the 4th, snow fell to the depth of 

 two inches. As is usual in the City during frost, fog was more 

 or less prevalent, and on the 14th was particularly dense and 

 disagreeable. The keenest frost of the month was recorded on 

 the 15th, when the thermometer fell to 21°, showing 11° of 

 frost. The severe weather somewhat relaxed towards the end 

 of the month, and on the 23rd the minimum thermometer stood 

 at 34°. 



The pressure of the atmosphere at the beginning of the month 

 was low and irregular, but from the 8th to the 22nd the readings 

 were all above 30*00 inches. During the closing days of the 

 month the barometer fell rapidly, and on the 28th was at 

 29*20 inches. 



Frost totalling 97° was registered on twenty days, while the
