Finally I give also the position of the vertex and the apex. 
The vertex lies in the square D,,, in the constellation Sagitta- 
rius, and has the coordinates (as determined from all stars brighter 
thau the 6" magnitude in Meddelanden Ser. B N:o 9) 
a = 282,75 = 18".85

The anti vertex lies in the square C,, in the constellation Ge- 
mini, and has the coordinates 
a = 102°.75 = 6".85 
À = + 19035 . 
The apex, as determined from all stars brighter than the sixth 
magnitude lies in the square B,, in the constellation Hercules (near 
the limit to Lyra), and has the coordinates! 
' These figures have not before been published. They are computed from the num- 
bers given in Meddelande Ser. B, N:o 9, Table Il.
