values. The change in the geographical position of the Fram has, of course, 

 also some influence upon the change in the pressure of the air from one 

 year to another in the same month. 



The smoothed curve gives a maximum of pressure, 761.47 mm., in April, 

 and a second maximum, 760.5 mm., in December. The lowest minimum, 

 758.09 mm., we find in July, and a somewhat higher minimum, 758.65 mm., 

 in February. The mean for the year is 759.55 mm. 



The following Table shows the Maxima and Minima of pressure in the 

 different months.
