TAKEN" AT WAHSFORD HOUSE, WATFORD, 1884. 225 
From the 15th there were therefore 17 days without rain, and if 
we add the first 3 days- of June, we have the very long period of 20 
days without, and of 27 with only 0*06 in. There was a thunder¬ 
storm on the 6th. At 4 p.m. on 11th the dry-bulb thermometer 
stood at 76°*2, and the wet-bulb at 52°-0, giving a relative humidity 
of only 29 per cent. 
Juke. —Of average temperature, rather dull, and very calm, with 
an atmosphere of average humidity and high pressure, and with a. 
small amount of rain, falling on an exceptionally small number of 
days. As there was in May a period of 17 days without rain (20 
with the first three days of June), so in June there was a period of 
19 days practically without, the only fall from 10th to 28th being 
0-01 in. on 22nd. On 5th and 6th together nearly 2 inches fell. 
The last week was warmer than the rest of the month.

The difference is chiefly in the max. temperature, which on every 
day during the last week exceeded 70°, and on only two days before 
then, 12th (73°*8) and 13th (79 o, 0), the mean temp, of these two 
days being 64° 0, about the mean of the last week. Max. temp, 
above 62° on 25 days, above 72° on 7 ; min. below 52° on 22, below 
42° on 1 (1st). There was a great prevalence of northerly winds. 
July. —Warm, rather dull, and very calm, with a rather dry 
atmosphere of average pressure, and with an average amount of 
rain. Max. temp, above 72° on 12 days, above 82° on 2 (4th and 
8th); min. below 52° on 10, below 42° on 1 (26th). July is 
remarkable for a series of severe thunderstorms, which lasted 
throughout the greater part of the month. They were experienced 
at Watford on the 6th (with 0*45 in. of rain), 9th (with 0*10 in.), 
and 27th (with 0-40 in.), and on several other days thunder was 
heard. In Symons’ ‘ Monthly Meteorological Magazine ’ (vol. xix, 
p. 118) the effects of the storm of the 9th at Baldock, Bygrave, 
Hitchin, and Stevenage are recorded. At Fairfield, near Hitchin, 
2*75 ins. of rain fell between 1*30 and 3 p.m. 
August. —Exceedingly warm, bright, and calm, with a dry 
atmosphere of rather high pressure, and a very small amount of 
rain. This was the hottest August for many years, but the mean 
temperature is considerably reduced by the comparative coldness of 
the last week.
