B}^ the courtesy of Mr. J. D. Cox I am enabled to add a table 

 of temperatures for the years 1896, 1897 and 1898. From these 

 it appears that the average maximum temperature for the period 

 is 57-7°; minimum, 42-9°; and mean for the period, 50-3°. During 

 the whole period of 1,095 daj-s the temperature fell to or Vjelow 

 freezing point on 128 occasions; and rose to 90° or over on 5. 

 The highest recorded temperature was 92°, and the lowest 22°. 

 The average daily variation between maximum and minimum is 

 10°, but it sometimes rises as high as 54°, and falls as low as 0°. 

 The greatest variations occur in the warmer months, and the 

 least in the colder. The averages for the months of June, July 

 and August are: max., 45-5; min., 33-8; mean, 396. And for 



December, January and February : max. 

 mean, 60-1.

The year 1897 was remarkable for the number of times the 

 temperature fell below the minimum, viz., 57. Yet the mean for 

 that year is higher than for either 1896 or 1898, although 1897 

 had very few abnormally warm days.
