the spring, April was rather warm; in the summer, July was the 
only exceptionally warm month; and the dryness of the autumn 
was owing entirely to the very small amount of rain which fell in 
September. March was the only month with the temperature 
much below the average, and July was the only month with it 
much above the average. In March and September the rainfall 
was exceptionally small; in January and February only was it 
much above the average.

J anttary.— A mild month, rather humid, with a cloudy sky, and 
a very heavy rainfall on a large number of days. The mean 
temperature was about 2^° above the average, the excess being 
more due, by half a degree, to the warmth of the days than of the 
nights. A little snow fell about the middle of the month and 
towards the end. The temperature varied greatly, there being 
a few very cold days, but no prolonged period of cold weather. 
The four days 11th to 14th, and the last four or five days in the 
month, were very cold. The range of temperature on the 21st 
was very great, being about 24|° (25°*4 to 49°'8) at St. Albans, 
26° (24° to 50°) at Berkhamsted, and 27° (23° to 50°) at Hertford. 
At St. Albans the 11th, 12th, and 13th were foggy, and there was 
a gale in the night of the 28th-29th. Mr. Mawley reports that 
“ although such a continuously wet month, there was more than 
the usual amount of sunshine.” 
February.— Bather cold, very humid, with a rather cloudy sky,

temperature was 1° below the average, the defect being due a little
