22 O. A. Åkesson 



The class in the classification according to Aß, where 

 — 0'.5 < Aß < — O'.i 



received the same number. 



The result of this division according to AX cos ß and Aß is given in the form 

 of correlation-tables. 



It happened very seldom that spots occurred for wliich these motions amounted

 hesitation, I have decided to exclude 

 all such observations in making 

 the correlation-tables and in the 

 computation of the characteristics of

In general, very great care must be
