 being neglected here instead of being taken as O'Ol to compensate 

 for falls of less than 0*005, which are rightly taken no account of. 

 The observations are taken at 9 a.m. at all the stations, and are 

 entered to the day of observation, except the maximum temperature 

 and the rainfall, which are entered to the previous day. 



Table I. — Results of Climatological Ohservations taken in 

 Hertfordshire in the Year 1897. 



The year 1897 was warm. This is the only feature in which 

 it differed materially on the whole from the average of the 

 previous ten years. The mean temperature exceeded one degree 

 of this average, the excess being a little more due to the mildness 

 of the nights than it was to the warmth of the days. From this 

 it follows that the range of temperature was rather less than usual. 

 The amount of moisture in the air corresponding with its warmth 

 (the relative humidity) was exactly the same as the average, but 

 as the air was warm there was a little more moisture (absolute 

 humidity) in it than iisual. The sky was rather more cloudy than 

 usual. The rainfall was about an inch and a half less than the 

 average for the last half-century.
