XXV. 
CLIMATOLOGICAL OBSERVATIONS TAKEN IN HERTFORDSHIRE 
IN 1888 . 
Ey John- Hopkinsox, E.L.S., E.G.S., E.R.Met.Soc. 
j Read at Watford , 26 th April, 1889 . 
At all the meteorological stations from which the report for the 
year 1887 was drawn up, observations have been continued in 1888, 
and therefore I have only to give similar tables to those for that 
year, and to make a few brief remarks on the general result. 
The mean temperature of Hertfordshire in 1888, as deduced from 
observations at our five stations, was exactly the same as in the 
previous year, and therefore again 1°*8 below the mean of our 
period, 1882-86. The mean daily range of temperature was 2°*0 
less than in 1887, the mean min. being l o, 0 higher and the mean 
max. l°-0 lower. The extremes of temperature were much less, 
and the relative humidity, amount of cloud, rainfall, and number 
of days of rain, much greater than in 1887. Although the rainfall 
was 1*29 in. less than the mean rainfall of our period, there were 
22 more days of rain, which doubtless partly accounts for the small 
range of temperature, the great humidity, and the cloudy sky. 
The general character of the weather in 1888 appears therefore 
to have been cold, damp, and gloomy, and although there was not 
a heavy rainfall, there were comparatively few fine days, rain falling 
on more than half the number of days in the year.
