RELATIVE HUMIDITY. ANNUAL PERIOD. 



The following Table has been made up in the same manner as the 

 corresponding Table for the force of vapour (p. 171). 



The mean for the year is 82.0 p. c. 



The march of the monthly means is not very regular. 



Smoothing the number by the formula |^ (a + 26 + c), we get the 

 row headed "Smoothed". These numbers give, by means of a para- 

 bolic formula, the following maxima and minima: 



Maximum Minimum Range 



January 17 83.7 p. c. May 22 79.2 p. c. 5.0 p. c.
