only three hours of sunsliine. On the other hand, anticyclonic weather 

 was of frequent occurrence in September, October, and December ; and 

 accordingly in these months sunshine was large, being absolutely the highest 

 hitherto recorded in September and October, and having been only 

 exceeded in December. It will be also observed that during these months 

 the difTerence of temperature between the two Observatories was much less 

 than usual, owing to the higher temperature of the anticyclones at the 

 top of the Ben. The highest monthly mean temperature at Fort William 

 v/as 58°-9 in July, or 2°-2 above the mean ; and at the top 43°-3 in the 

 same month, or 3°"0 above the mean. The month of greatest excess 

 above the average was November, whose mean temperature at Fort 

 William was 46°-7, or 4°-l above the mean, while at the top it was 31°-3 

 or 3°'2 above the mean. This great excess of temperature was about the 

 same in all parts of Scotland, and was occasioned by an extraordinary 

 predominance of south-westerly wind, which exceeded any observed in 

 November dui-ing the past forty years. The sunshine was markedly 

 deficient, and hence temperature at the top was relatively lower than 

 at Fort William. The following show the deviations of the monthly 

 results from their respective )neans : —

The maximum temperatui-e at the top was G3°-5 on June 30, and 

 81°-5 at Fort William on July 1. The minimum temperature at the top 

 was 0°-7 on January G, and at Fort William •20°-S on January 6. 



The above minimum temperature 0°-7 is absolutely the lowest yet 

 observed on the top of Ben Nevis. The conditions under which it 

 occurred are seen in the following extract from the day's observations : —
