Observations: The standard adopted is the mean of the mean 

 daily maximum, mean daily minimum, mean of the 

 dry bulb readings at 9'^ and at 21'^. In some 

 months the maximum or minimum readings were 

 unreliable or wanting, and the values in italic 

 have been computed by applying corrections 

 (Table B) based on the long series of reliable 

 records,
