At Fort William the mean atmospheric pressure for the year was 

 29*855 inches, being 0-011 inch higher than the average of the forty years, 

 1856-95. The mean at the top of Ben Nevis, reduced to 32° only, was 

 25"298 inches, and was nearly the average of the observations made since 

 the opening of the Observatory in December 1^83. The difference for 

 the two Observatories was thus 4-557 inches for the year, being nearly the 

 average difference of past years. At the top of the mountain the absolute 

 highest pressure for the year was 26-029 inches in September ; and at 

 Fort William 30-58-t inches in December. 



The differences from the mean monthly pressure very greatly exceeded 

 the averages in October and November, the excesses respectively being 

 for Fort William 0-278 inch and 0-280 inch, and at the top of Ben Nevis 

 0-234 inch and 0-242 inch. The evidently anticyclonic character of the
