The triangle VII—VIII—XII was included in view of the regu- 
lation of the angles: it was not used in the computations which as 
a control gave log VIII—XII = 
was used.

The strikingly large corrections which have been made here in 
the triangles VIII—IX —XII and V—VIII—IX respecting the angles IX 
are caused by the fact that the bearing VIII—IX, in spite of the 
rather good agreement of the sums of the angles, has in reality not 
been measured. The facts of the case are: at the survey made from 
Station VIII the pointing of Cairn IX failed altogether in the first set, 
and as far as the other two sets are concerned there is the following 
entry in the observation journal: “The pointing uncertain; the cairn 
not visible; background unfavourable.” However, the sharp form of 
Harefjeldet (Cairn IX) seen from the south made it possible to point 
Station IX fairly well, irrespective of whether one could distinguish 
the cairn or not. A test of the sight VIII—IX was thus necessary, 
and for this reason the computation of the quadrangle V—VIII— VII — XII 
was the first thing to be done. In the triangle VII—IX—XII the 
two sides УШ- XII and IX—XII were determined. Furthermore the 
angle at XII was given, being the sum of angle VII—XII—IX and
