The result for the year 1844 is very marked. The pressure of the wind is a maximum when the moon is 

 farthest north and it is constant for each of the gi'oups from four days after the moon was farthest north till 

 four days before it was farthest north ; the pressure of the most northerly group is twice as gi'eat as that for 

 the southerly groups.
