THE WINDWARD SIDE OF THE WIND-ROSE. 



As the place of observation is not the same in the same month of the diffe- 

 rent years, we cannot take the means of the frequency-numbers for the 3 (or 2) 

 years in order to get a fuller representation of the monthly distribution of the 

 winds. There is apparently a change in the direction of the prevailing winds 

 along the track of the Fram. The winds have mostly a tendency to change their 

 direction against the sun, the farther West the place of observation lies. The 

 fuller discussion of this subject must be deferred until we can take into consideration 

 the prevailing movement of the air in each month, and the distribution of air- 

 pressure.
