Aperiodic Range. 



The regular annual period of the Minima and Maxima is a little 

 broken in February, where the values are apparently too high in re- 

 lation to January and March. 



The aperiodic range is highest in the winter months and lowest in 

 the summer months. The smoothing^ of the numbers gives a maximum 

 in March and April, and a minimum in August and September.
