ABNORMAL VARIATIONS AT TORONTO. 119 



With winds from N.E., E., and S.E. the air is relatively damp, 

 and with winds from W., N.W., and N. the air is relatively dry. The 

 most damp wind is from the East and the most dry wind from N.W. ; 

 hut the range is small, amounting only to 9.0. 



The average change in humidity in twenty-four hours without 

 regard to sign is 8.9, the greatest monthly change being 12.4 in June, 

 and the least 7.3 in February. 



The humidity increases in twenty-fours with a resultant wind from 

 N.E., E., S.E., and S., and diminishes with a resultant from S. W., 

 W., N.W., and N., the greatest increase of humidity being with a 

 resultant wind from E , and the greatest diminution with one from 

 N. W. The range between the E. and N. W. winds is, however, only 

 6.1. 



It may be remarked with reference to the preceding paragraphs 

 that the observations of three years are materials too scanty to justify 

 our regarding as conclusive the results that relate to humidity. 



CLOUDINESS. 



If the compass be divided into four quadrants designated respectively 

 by their middle points, the means of cloudiness found to accompany 

 winds blowing from points included within these quadrants, together 

 with their differences from the general mean, 59, were found from 

 upwards of 13,000 observations in the years 1853 to 1859 to be as 

 follows, the whole hemisphere being 100.
