From these dates I have calculated p and as control, by 

 the means of the j9:s already calculated, determined jt, which I 

 have then compared with the values of 7t given by DuNÉR(7r = 

 heliographic polar distance). On two different occasions I could 

 not make them agree with Duner, which is the reason that I 

 have excluded those observations viz. second observation 1887 

 June 18 TT = 75° and 1887 June 11 7r = 60°; besides the 

 following observations are excluded viz. 1887 Jan. 3, 4, 15 and 

 Jan. 16 7r = 75°, as the dates given by Dunér to determine p are 

 too aproximate even to determine in what quadrant the obser-
