Experimental Plots at Rotliamsted, from 1864 to 1883, 421 
July was a month remarkable for the variations of temperature 
in Great Britain ; in some districts the temperature exceeded 
90, and for days together 80, while in others the month was 
cold, cloudy, and wet. In the wheat-districts it may be said 
to have been a very hot and dry month. The first week 
in August was fine and dry, after which the weather to the 
end of the month was cold with almost constant rains, which 
did considerable injury to the wheat. 
Thirty-ninth Season, 1881-82. 
October was excessively cold, with violent gales, and rainfall 
slightly below the average. November was exceedingly warm, 
with rainfall also slightly below the average. December was 
alternately warm and cold, the temperature and the rainfall 
being about the average. 
January was excessively warm and dry, spring flowers being 
in bloom. February and March were also both warm and dry, 
and vegetation was very forward ; indeed, from November to 
the end of March the weather may be described as being most 
favourable for the crops. April was generally warm until 
towards the end of the month, with more than an average rain-
