NOTE 



ON THE TEMPERATURE OF SEPTEMBER, 1895. 



BY MR. A. COLLENETTE, F.C.S. 



September this year has proved to be the warmest 

 September recorded since 1843, when Dr. Hoskins' records 

 commence. The month has been remarkable, not only for its 

 average temperature, but for the actual maximum recorded. 



The average temperature for September for fifty-two 

 years is 58*1 °, which this year has been exceeded 5'5°, A 

 mean temperature exceeding 60° for September justifies the 

 term "hot." I have, therefore, for comparison, tabulated 

 below all Septembers since 1843, with mean temperatures of 

 60° and over. Including the past month there have been nine 

 such.
