J. HOPKINSON-METEOROLOGICAL OBSERVATIONS 
1899 and 1900. The mean daily range of temperature was about 
a degree greater than usual, owing chiefly to the coldness of the 
nights. The air, at 9 a.m., was drier than usual, its relative 
humidity being 2 per cent, less than the average, and, at the same 
hour, there was rather less than the average amount of cloud. 
The sun shone on the average throughout the year 22 minutes 
a day longer than usual. The rainfall was small, and the number 
of days of rain was much below the average. Westerly winds 
prevailed, and south-westerly were the next in frequency. 
February was a very cold month, being much the coldest in the 
year; July was very warm. In April and June the air was very 
dry, and in each of the five months April to August the sky was 
much brighter than the average. Very little rain fell in January, 
June, and November, but December was an unusually wet month, 
and March and April had much more than the average amount of 
rain. In each of the five months May to September, and in 
November, rain fell on a very small number of days.

The Winter of 1900-01 (Dec. to Feb.) was mild, owing rather 
more to the warmth of the nights than of the days, the mean daily 
range of temperature being rather less than usual. The air was 
of average humidity, and the sky was of average brightness. The 
duration of sunshine averaged 20 minutes a day less than usual. 
The rainfall was rather small, but there was more than the average 
number of wet days. South-westerly and westerly winds greatly 
prevailed, in equal proportion. 
The Spring (March to May) was rather cold, owing more to the 
coldness of the nights than of the days, the mean daily range of 
temperature being rather great. The air was much drier than 
usual, and the sky was of average brightness. The duration of 
sunshine averaged 18 minutes a day more than usual. The rainfall 
was rather heavy, but there was only about the average number of 
wet days. North-easterly winds prevailed, south-westerly and then 
northerly being the next in frequency. 
The Summer (June to August) was very warm, owing entirely 
to the warmth of the days, the mean daily range of temperature
