269 
Hempstead, and 1 67 in. at Northaw, and 2T3 ins. at Bayfordbury. 
On the lOtli it was at least half an inch at 25 stations. On the 
25th it was at least half an incli at 18, and at least an incli 
at 4 of these: 114in. at Shenley, 1*21 in. at Hew Barnet, 
1-32 in. at Bedford Avenue, Barnet, and 133 in. at Summer- 
hill, Barnet. On the 30th it was at least half an inch at 
10 stations. There were thunderstorms on the 7th, 8th, 9th, 
10th, 25th, and 30th. 
July.— A very cold month, with a very humid atmosphere, an 
exceedingly cloudy sky, and a rather small rainfall on about the 
usual number of days. The low mean temperature was chiefly 
due to the coldness of the days, the mean maximum being about 
six degrees below the average and the mean daily range four 
and a half degrees below it. Colder, damper, and much more 
cloudy than either June or August, this mid-summer month 
seemed to give a gloomy character to the whole summer, and yet 
after the first few days very little rain fell. The 3rd was the 
wettest day at one station, the 4th at one, and the 5th was 
the wettest at 52 stations. The rainfall reached at least half an 
inch at one station on the 2nd, at 2 stations on the 3rd, and at 
32 on the 5th. 
August.— A little colder than usual, with a humid atmosphere, 
a cloudy sky, and rather less than the average rainfall but many 
wet days. The low temperature was entirely due to the coldness 
of the days, the nights being warmer than usual, and the mean 
daily range therefore small. Thus August was similar in several 
respects to July, though not so abnormally cold, humid, or cloudy. 
The rainfall was distributed much more equably over the month, 
the 4th being the wettest day at 5 stations, the 5th at 10, the 
18th at 10, the 25th at 15, the 28th at 2, the 29th at 10, the 5th 
and 25th at one station, and the 25th and 29th at one. On the 
4th at least half an inch of rain fell at 5 stations, and over an 
inch at 2 of these: 122 in. at Bulbourne and 1*43in. at G-rove 
Lodge, Tring. On the 5th at least half an inch fell at 7 stations, 
and from an inch to nearly two inches at 3 of these : 105 in. at 
North wood, l - 74 in. at Moor Park, and L98 in. at Croxley Green. 
On the 18th it reached at least half an inch at 2 stations, on the 
23rd at 2, on the 25th at 3, and on the 29th at 5. There were 
thunderstorms on the 4th, 5th, 25th, and 29th. 
September. — Bather cold, with an atmosphere of about 
average humidity, a rather cloudy sky, and an exceedingly small 
rainfall on a few days only. The low temperature was due more 
to the coldness of the days than of the nights, the mean daily 
range being rather small. The last four days only were warmer 
than usual, having a mean temperature at St. Albans of 59 - 2°. 
All the rain fell in the first half of the month, except a small 
quantity on the 29th and 30th. The 13th was the wettest day 
at 37 stations, the 14th at 16, and the 13th and 14th were the 
wettest at one station. At least half an inch of rain fell at 
3 stations on the 13th and at 2 on the 14th.
