weather was on the whole fine, although a good deal of rain 
was recorded. 
July.—Wet unsettled weather predominated, although 
pressure was above the normal. The mean temperature of 
the days was half a degree under, but the nights over a 
degree above the mean, the diminished range being due to 
cloudy skies. With the exception of a heavy fall of rain on 
the 8th, the meteorological conditions were featureless, most 
of the elements approximating closely to their averages. 
August.—Although rather a cool month, the weather, as a 
whole, was much finer than in any August during recent 
years. The rainfall amounted to little more than half the 
average, and a good deal of sunshine was recorded, there being 
only one sunless day. 
September—Exceptionally dull weather prevailed during 
practically the whole month, only 60 hours bright sunshine 
being recorded, or only 16 per cent. of the possible. This 
was the smallest amount of sunshine registered in September 
since 1881, which had 58 hours. In the first fortnight 
there were eight sunless days, only 24 hours sunshine 
being recorded. As the result of the sunless weather, the 
mean of the day temperatures was over two degrees below 
the average, while the night values were about a degree above 
the normal. Heavy rain fell on many days, the downfall for 
the month being a third greater than the mean. There was 
a great deal of mist during the prevalence of the easterly 
current, which continued till the 14th. 
October.—The weather of October was very cold, the mean 
temperature being 4°°0 below the normal, and the lowest 
_since 1817, when the depression of temperature amounted to 
5°2: the only other instance of such exceptional cold so 
early in the season was in 1778, when the October mean was 
4°°6 below the normal. Sunshine was deficient, and heavy 
rainfalls were frequent, over seven-tenths of an inch falling 
on the 7th, 10th, 18th, and 19th. Snow fell on the 10th. 
The month’s sunshine total of 58 hours was the lowest since 
1886, which had 34 hours. 
November.—Dry sunless weather prevailed throughout 
the month. Only 0°65 inch of rain fell—the lowest for
