OBSEBVATIONS OF TEMPERATURE AT CLIFTON. 15 



were three very liofc days — the llth, 12th, ^ and ISth — 

 followed by a period of cold weather. June was warmer 

 than usual by more than a degree ; the highest temperature 

 reached was 77° on the 19th. Both in July and August 

 the temperature was fairly uniform, there being no excep- 

 tionally hot or cold days; but both months were colder than 

 usaal. In September, however, there was a period of very 

 hot weather, the temperature being above the average from 

 the 8th till the 21st. There were only five days on which 

 the temperature was below the average. The highest tem- 

 perature recorded during the whole year was 791° on the 

 12th of this month. The temperature of October presented 

 no special features. In the end of November there was a 

 period of very cold weather, from the 23rd till the end of 

 the month. In December the temperature was considerably 

 above the average till the 18th, when a period of exception- 

 ally cold weather set in, with frost on the ground till the 

 28th. The mean temperature was below freezing point 

 from the 20th till the 25th. 



It is to be noted that the situation of the thermometers 

 was changed in April. There was also an interruption in 

 the observations of ground temperature from the 28th of 

 October till the 1st of November on account of the breakage 

 of the thermometer. The lowest ground temperature for 

 December is also uncertain on account of the falls of snow. 



In conclusion I would draw attention to an error in the 

 table of Mean Temperatures for 1890, on page 293 of the last 

 volume of the Proceedings of the Society. The mean tem- 

 perature of the last ten Aprils ought to be 46*15°, instead of 

 44'14° as then stated. My attention was drawn to this error 

 by the late Dr. Burder, and I cannot but seize this oppor- 

 tunity of expressing my sense of the loss which students of 

 meteorology have sustained in his lamented death.
