72 METEOROLOGICAL OBSERVATIONS AT CLIFTON. 



38-89 degrees, as compared with the average of the previous 

 ten years of 40*20 degrees. This low mean was caused by a 

 period of very cold weather, extending from the 12th to the 

 21st, the temperature for the rest of the month being nearly 

 normal. The mean daily temperature was below freezing 

 point from the 16th to the 19th, both included, and the 

 thermometer never rose to freezing point on two of these 

 days. 



The lowest temperature in the screen was 17*3 degrees 

 on the 17th, and the highest temperature 50 degrees on the 

 8th. 



As regards pressure, the month ma}'' be divided into two 

 periods, one of high pressure from the 8th to the 14th, and 

 one of low pressure from the 14th to the 26th. On the 

 19th the extremely low reading of 29 043 inches was ob- 

 served. 



March. — This again was a very cold month, the mean 

 temperature 37'59 degrees, being 4 12 degrees lower than the 

 average of the preceding ten years. In fact, there were 

 only five days in which the mean daily temperature was 

 above the average, and on eight days it was below freezing 

 point. There was frost on the ground on 23 days, the 

 lowest temperature recorded being 22-4 degrees on the 13th. 



In the first fortnight the mean temperature was about 

 freezing point. There is nothing of special interest to be 

 noted in the barometrical readings, except the very high 

 barometer of the 30th, 30*610 inches. 



April. — The mean temperature was 47*49 degrees, or 

 about 10 degrees higher than the mean for March, and 1*35 

 degrees higher than the average of the last ten Aprils. 

 There were, however, very great variations of temperature ; 

 the maximum thermometer reading over 70 degrees on the 

 3rd and 6th, and falling as low as 42 degrees on the 13th.
