AT TORONTO FOR THE YEAR 1864. 



109 



The mean deviations of temperature in the four seasons, with their 

 proper signs, were : —0°.33 in Winter ; +0°. 79 in Spring; +2^27 

 in Summer ; and — 0°.60 in Autumn. 



As regards rain and snow, there was, on the whole year, an excess 

 amounting to 0.655 inches of water. An excess occurred in Winter, 

 Spring, and Autumn — the total precipitation exceeding the average 

 by 1.136 inches in Winter, 1'788 inches in Spring, and 0.186 inches 

 £a Autumn. In Summer, the rain was deficient as compared with 

 the average by 2.405 inches. This deficiency was not much greater 

 than that of the summer of 1863 ; but the distribution among the 

 three summer months was very different in the two years, for while 

 in. the summer of 1863 there was a moderate deficiency in each 

 month, the rain in June, 1864, was less than one-fifth, and in July 

 little over one -third of the average fall ; that of August being above 

 the average in the ratio of 5 to 3 nearly. 



In the following summary several of the results for the year 1864 

 are compared with the averages derived from a series of years as well 

 as with extreme values of analagous results given by the same series.
