BY THE REV. E. F. WHEELER, M.A. 



455 



different months has been drawn out by Mr. Glaisher from the 

 records of the Royal Observatory at Greenwich, extending over 

 a period of ninety-eight years, 1771-1869. 



The editor places side by side the average temperature of 

 Wylam for fourteen years, as drawn from Mr. Atkinson's obser- 

 vations. 



The two series will show, to some extent, the difference of 

 temperature for each month between the North and South of 

 England at a glance. The editor has no series of observations 

 extending over a longer period than Mr. Atkinson's at his dis- 

 posal. 



Greenwich. Wylani.

Febmary 38-4° 39-36° 



March 41-0° 40-49° 



April 46-0° 46-02°

Greenwich. Wylam. 



July 61-4'' 59-07° 



August 60-7° 58-87° 



September 56-5° 54-84° 



October 49-7° 48-09° 



November 42-4° 41-11° 



December 39*2° 39-92° 



It thus appears that the average temperature of the three 

 winter months, December, January, and February, is higher in 

 each case at Wylam than at Greenwich.
