Read at Watford, I8tk April, 1893. 



Observations were continued during the year 1892 at the five 

 stations for which the reports for the five previous years have 

 been drawn up, and therefore I give the usual series of tables. 



The mean temperature of Hertfordshire in 1892, deduced from 

 observations at these five stations, was 0° 5 below that of the five 

 previous years, and l°-8 below the mean of 1882-86. The year 

 was therefore a decidedly cold one. The mean daily range was 

 0°-8 more than in 1887-91, and 0°-l more than in 1882-86. The 

 extreme range was less than in 1890, and greater than in 1891. 

 The ail- was a little less humid than in the five previous years, the 

 amount of cloud was rather less, and the rainfall rather greater, 

 but on a smaller number of days. The weather was very cold 

 from the early part of spring late into autumn, and, while dry in 

 spring, wet and humid in the latter part of summer and in autumn. 



The observations are made 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.
