June. — The weather throughout this month was very broken and 

 variable, being influenced by small, shallow disturbances which fol- 

 lowed each other across the Kingdom in fairly quick succession. The 

 mean temperature was about the average; in some parts maxima 

 were registered exceeding 80^, but at Wisley the highest point reached 

 was just below 80*^, and on most days it failed to rise to 70^. There 

 were thunderstorms in several districts from the 6th to the 8th, but the 

 distribution of rainfall over the Kingdom was peculiar; in many parts 

 of the northern half the total did not amount to an inch, whilst in 

 the south-west of England and in many parts of Ireland there were 

 totals as large as five inches ; at Wisley it was less than an inch and a 

 half. The largest totals of sunshine were experienced in the north ; 

 but as a rule it was less than the average in all districts, the smallest 

 totals occurring in Ireland; London had 156 hours; Wisley, 175; and 

 Yarmouth, 242 hours; whilst in Kings Co., Ireland, only 131 hours 

 were recorded. There were no very strong winds during the whole 

 month.

July. — The outstanding feature of this midsunnner month was the 

 striking absence of summer heat over those parts of the Kingdom 

 which are usually the warmest at this season of the year, namely, 

 the eastern and central districts. At Wisley the highest temperature 

 recorded throughout the month was but 74°, and the thermometer 

 touched 70^ only on four days, and this was characteristic of the
