continued till about the 19th. when, for a few days, the 

 atmospheric conditions were less severe, but dull and unpleasant. 

 Frost again occurred on the 22nd, and held more or less keen till 

 the end of the year. 



The frost recorded this month — 128° for 17 days — is the highest 

 monthly record for the year, and the lowest reading of the 

 thermometer was taken on the 15th, when it fell to 15°, showing 

 17° of frost. 



The average maximum and minimum thermometers were 39° 

 and 30° respectively, as compared with 48° and 40° for December, 

 1898. 



The rainfall for the month was moderate, at 2*94 inches, and 

 there were 16 dry days. 



The barometer readings show that the atmospheric pressure 

 during the month was of a very variable nature. Until the 21st 

 it varied from 29 -30 to 30-10, thereafter falling steadily to 29*30 

 on the 28th, and very sharply to 28 "26 on the 30th. This was 

 the lowest reading of the year. 



Comparing the records with those of previous years, we find 

 that the rainfall — 41*67 inches — is the heaviest recorded within 

 the last ten years, the next being 41*48 inches in 1894. The 

 month in which the highest rainfall was recorded was December, 

 with 5*64 inches, January coming very close with 5*61 inches. 

 The wettest day of the year was the 18th May, when 1*50 inches 

 was recorded. Other notable days of rain were January 19th, 

 1*20 inches; March 29th, 1*20 inches; and November 4th and 

 8th, which had 1*45 and 1*01 inches respectively. The driest 

 month of the year was August, and in 1898 the driest month was 

 July. The number of dry days was 193, compared with 212 in 

 1898.
