1.9325 : }/n — we cannot attach any importance to this slight positive skewness. 

 Even as regards the latitude motions we are practically entitled to put S = 0. 



The same pervading positive excess which we have already met with in the 

 stud}' of the longitude motions, we also find in the motions in latitude. As it 

 appeared tliat the dispersions also of the latitude motions diminished with increasing 

 spot-area, I have computed the characteristics of the motions of tlie spots of diffe- 

 rent sizes. From reasons before mentioned the material has been divided according

to the logarithm of the spot-area, in the same manner as in discussing the positive 

 excess of the motions in longitude. 



In table XXIII I have brought together the characteristics of the motions of 

 the different spot-sizes The spots for which w is < 0.8 or > 3.2 are not given in 

 the table, because of their being to few to admit of a calculation of the higher 

 characteristics. As seen from the table the excess of the motions of the different 

 groups is of about the same size as it was before the dividing of the material.
