The mean temperature for Spring from all the observations was .... 47'6 
The mean temperature for Summer from all the observations was . . . 6 TO 
The mean temperature for Autumn from all the observations was . . . 50’5 
The mean temperature for Winter from all the observations was . . . 39'3 
The mean temperature for the Year from all the observations was . . . 49'6 
By taking the difference between the mean temperature of each period from all the 
observations, and the mean temperature for the same period in every year, the follow- 
ing Table was formed.
