ÖFVERSIGT AF K. VETENSK.-AKAD. FÖRHANDLINGAR 1899, N:0 2. 79 



vations are made. For the group of observations it = 90° 1 

 have got no dates, but as the observations in all other latitudes- 

 are always made, the same day, in the same quadrant, with 

 only a few exceptions in June 1887, I have assumed that also 

 the corresponding observations on the latitude 7t = 90° are made 

 in that same quadrant. Thus for this group I could calculate 

 p from the 7C published by Dunér. If my assumption as to 

 the quadrant in which the observations are made should not 

 always be true, this is of no very great consequence. The values 

 v (see Dunér pag. (34 — 72) are not equal to the observed v^ ;. 

 the foUowing relation exists between v and v, 



v = U] sec rj 

 the reason why I had to determine v^ from the published u; 

 the i^:s employed by Dunér are tabulated pag. 47. 



Each v gave me one equation of condition, and thus I got 

 the foUowing equations all with the same weight.
