The above period represents the mean temperature for the Midsummer period of 1888 ; over the whole ten weeks, the meai 

 loss of heat for the kingdom is shown to have been 3*3 degrees for each day. Rainfall is drawing nearer the normal, it: 

 distribution very equal ; but the distribution of solar favours is becoming remarkably unequal.
