January. —A very warm month, less humid and more cloudy 
than usual, with a very small rainfall on a small number of days. 
Both days and nights were warm, the mean minimum and mean 
maximum temperatures being each about four degrees above the 
average. The duration of sunshine was rather longer than usual. 
The prevailing direction of the wind was westerly, south-westerly 
winds being next in frequency. The weather was very warm for 
the first twelve days, rather colder from the 13th to the 19th, 
again very warm from the 20th to the 24th, and colder for the 
last week. The maximum temperature exceeded 50° on the first 
four days, on the 9th and 10th, and on the 21st and 22nd; and the 
minimum only sank below 32° on ten days at Berkhamsted and 
twelve at St. Albans. 
February.— Yery cold, with a very humid atmosphere, rather 
more cloudy than usual, and with a rather small rainfall on the 
usual number of days. The low temperature was due much more 
to the coldness of the days than to that of the nights, the mean 
daily range being small. The duration of sunshine was shorter 
than usual. North- easterly winds prevailed, but not to any great 
extent; the next in frequency were south-easterly. The last week 
only was warm, the temperature never falling below 32 Q , while it 
fell below this point every day for the first three weeks. There 
was a “glazed frost” or “silver thaw” on the night of the 2nd, 
fine sleet and rain freezing on reaching the ground. 
March. — A warm month, with a humid atmosphere, a cloudy 
sky, and about an average rainfall on the usual number of days. 
The temperature of the days was rather more in excess of the
