Report on the Weather of October, November, and December 1863, as 

 compared with the previous Six Years. By Mr Alexander Buchan. 



The first three tables present a detailed statement of the tem- 

 perature in October, November, and December, during the seven 

 years ending with 1863, as observed at Balfour, near Markinch, in 

 Fife, one of the stations of the Scottish Meteorological Society. It 

 is the nearest station to Edinburgh at which full and well-authen- 

 ticated observations on temperature have been made for so long a 

 period, and, besides, its position is such as to represent fairly both 

 sides of the Forth. 



Table I. gives the mean monthly temperature of the day and of 

 the night, and the mean temperature of these months for the past 

 seven years, and a comparison of 1863 with the means of the pre- 

 vious six years. From this Table, we learn that the peculiar features 

 of the weather of October, November, and December last, as respects 

 temperature, were as follow : — 



In October, the mean temperature was nearly a degree (0°-8) above 

 the average of the month ; but whilst the mean temperature of the 

 day was less than half a degree (0°'4), that of the night was about a 

 degree and a-half (l°-4) above the average, thus indicating a cloudy 

 sky and comparative absence of frost. At the Botanic Garden, the 

 thermometer fell only three times to freezing, the lowest being 28°*0 

 on the night of the 6th. This frost continued but for a short time, 

 and very little damage was done except to Heliotropes ; dahlias 

 were only slightly affected.
