METEOROLOGICAL OBSERVATIONS AT WISLEY IN 1904. 651 



Owing to the removal of the instruments to Wisley, the average values 

 of temperature and rainfall based on the long series of observations made' 

 at Chiswick are no longer available for comparison with the monthly 

 means derived from the observations from the new station. Fortunately,

however, there exist series of observations made at places sufficiently roar 

 to Wisley to allow of their use for the determination of averages which no 

 doubt approximate very closely to the average values for Wisley itself ; 

 and I have used these provisionally, until it becomes possible to calculate
