January. 
Tiie severe frost which set in on the 25th November, 1890, and 
continued until the 22nd January, 1891 (a period of fifty-nine 
days), has been commented upon in detail in a former paper (see 
ante, vol. v. p. 191). After the break up of the frost, the weather 
was comparatively mild until the end of the month. The mean 
temperature was, however, as much as 5 degrees under the average, 
owing to the great cold of the first three weeks, during which time 
the daily deficiency averaged 10 degrees. 
February. 
This month presented many unusual meteorological features; one 
of the most notable of which was the smallness of the rainfall, the 
total amount measured being only .07 inch, of which nearly 
one half was made up of moisture deposited by wet fogs. There 
does not appear to have been such a dry month in East Anglia 
since September, 1865, nor so dry a February since 1857. The 
temperature (the mean of which was but little under the average) 
was extremely variable during the last six days of the month, the 
daily range on many days exceeding 30 degrees, and on the 28th 
exceeded 37 degrees. On the latter date, the thermometer rose to 
64 degrees, which appears to be a higher temperature than any 
registered in February since the year 1846. Another notable
