had become excellent. At Wisley it was reported that the " prospects 
for fruit were magnificent, notwithstanding that much of it had fallen 
with the hot weather " ; and that " the caterpillar pest was bad both 
on fruit and forest trees. All vegetable, corn, and hay crops were 
splendid." Other reports spoke of " wonderful growing weather " 
in Yorkshire and elsewhere, whilst generally, all over the kingdom, 
the close of the month found " the face of the country presenting its 
normal aspect." 
The following are the mean results obtained from the observations 
made at Wisley :

Mean relative humidity of the air at 9 a.m. (complete saturation being repre- 
sented by 100), 73 per cent. 
Rain fell on 9 days, to the total depth of 2*20 in. (equivalent to about 10 
gallons of water to the square yard). Heaviest fall on any day 0*73 in., on the 
29th. 
The prevailing winds were from between south-east and north-east. 
The average velocity of the wind was 5 miles an hour. 
There were 208 hours of bright sunshine, equal to 44 per cent, of the greatest 
possible amount. 
There were but 2 days on which no sunshine was recorded. 
June. — The weather during June exhibited some curious and 
apparently contradictory features. It was a bright and sunshiny 
month, and on the whole warmer than June generally is, but the 
distribution of warmth throughout the month was quite unusual. 
During the first fortnight the daily maxima gradually increased until 
the days became excessively hot, and in many places the thermometer 
rose to nearly 90 °, and in some parts of south-east England higher 
still. At Wisley the highest maximum reached was 89 0 on the 17th, 
but only a week later a ground frost occurred in the night, and did 
damage to potatos and other tender things in some sheltered parts 
of the grounds, and the weather becoming still cooler as the month 
drew to a close, there was presently brought about a cold spell, in 
which the temperature fell considerably below its normal for the time 
of year — indeed, in the east of Scotland the minimum on the last day 
of the month was so low as 32 °, whilst the mean temperature for 
the week was more than 6° below the normal. The rainfall was 
generally less than the average, but in some places it greatly exceeded 
it, owing to the occurrence of excessively heavy local rain-storms 
about the middle, and again near the close, of the month. In the 
first of these there was an unprecedented fall over western London, 
when amounts varying between two and a quarter and four and 
three-quarter inches were measured, the centre of the storm, and the
