246 Meteorology of New Haven. 



We conclude therefore, finally, that during the past 86 years there 

 has been no permanent change at New Haven either in the mean 

 temperature of the year, or in that of any of the separate months ; 

 and that there has been no permanent change in the average date of 

 occurrence of the last frost of spring, or the first frost of autumn — 

 of the first snow of winter, or the last snow of winter — or in the 

 average date of flowering of fruit trees, such as peach, cherry, etc.
