223 



Information as to the stations lias been given in my paper on 

 " The Climate of Hertfordshire " in the eleventh volume of our 

 'Transactions' (pp. 125-126). The averages with which the 

 results are compared are those for the twelve years 1887-1898 

 as there given, except for the rainfall, which is compared with 

 the average for the sixty years 1840-1899. 



The year 1906 was very warm and rather wet ; the air was 

 dry and the sky of average brightness. Eain fell on a rather 

 large number of days. 



The mean temperature was 49-8°, being 1-5° above the average; 

 the mean daily range was 16-2°, being 0-3° above the average, 

 the excess of temperature thus being a little more due to the 

 warmth of the days than to that of the nights. The rainfall 

 was 26-49 inches, being 1-72 in. above the average for the 

 decade 1890-99, and 6-34 in. above that for the 60 years 

 1840-99. The number of wet days was 172, being 4 more than 

 the average for the 30 years 1870-99.
