J. HOPKINSON THE WEATHER 



are given ; those for Bennington, Berkhamsted, and St. Albans 

 being from tliermometers in Stevenson screens, and those from 

 New Barnet from thermometers under a Glaisher stand. 



Information as to the stations has 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 1905 was, on the whole, warm and dry ; the air was 

 of average humidity, the sky rather more cloudy than usual. 

 Though the rainfall was deficient in quantity, in frequency it 

 slightly exceeded the average, and there were many heavy falls. 



The mean temperature was 48-9°, being 0-6° above the average ; 

 the mean daily range was 14-5°, being 1-4° below the average, 

 the excess of temperature thus being due to the warmth of the 

 nights. The rainfall was 23-48 inches, being 1-29 ins. below 

 the average for the decade 1890-99, and 2-66 ins. below that for 

 the 60 years 1840-99. The number of wet days was 169, being 

 one more than the average for the 30 years 1870-99. 



Compared -with the average, January and December were warm 

 months, and February, March, and July were very warm ; 

 August and September were rather cold, and October and 

 November were very cold. The air was dry in January, July, 

 and October, and very dry in May ; it was moist in November 

 and December. The sky was bright in January, February, May, 

 and July ; it was cloudy in June, August, and September, very 

 cloudy in April and December, and rather cloudy in March. 

 March and June were wet months, and April, Augiast, and 

 November were rather wet ; all the other mouths were dry, 

 October having the greatest defect in rainfall from the average. 

 Rain fell on many days in March, April, August, and November, 

 and on very few days in May and July.
