^bscrbations of temperature at 

 Clifton College, 1890. 



By I). PJNTOUL, M.A. 



r I 1HE following tables and diagrams contain a general 

 -*- record of the temperature of the year. It will be seen 

 that the mean temperature is slightly above the average of 

 the last ten years. The month of January was much warmer 

 than usual, the mean temperature being 4*35° higher than 

 the normal. The year, however, is distinguished most for the 

 remarkablv cold weather, which commenced on the 25th of 

 November and continued without intermission till the 22nd 

 of January, 1891. The mean temperature of December, it 

 will be seen, is • more than nine degrees lower than the 

 average, and no December in the last ten years has had a 

 mean temperature approaching it within eight degrees. The 

 mean daily temperature was below the average on every day 

 from the 25th of November till the end of the year, and not 

 only so, the maximum daily temperature never rose so high 

 as the average mean daily temperature during that time. 

 The mean temperature was below freezing point from the 

 9th of December till the end of the year, and on fourteen 

 days the thermometer never rose above freezing point. In 

 this way the winter of 1890-1891 will long be memorable 

 for its long-continued frost. 



The diagrams show the daily maximum and minimum 

 temperature in the shade, the intermediate line being the 

 course of mean temperatures and the smooth curve repre- 

 senting the average temperature deduced from observations 

 by the late Dr. Thomson of College Road — observations 

 extending over more than twenty 3''ears.
