with the corresponding mean of the readings on the horizontal circle

The clock correction not being known beforehand, the azimuth 
is computed from the zenith distance. 
In this manner we get:

Station pointing. In the table below the results of the ob- 
servations at Haystack, Peak C and Remote Peak are left out as 
being of no importance, as far as the computation is concerned. On 
the other hand both of the observations performed in the case of 
Cairn VI are included, seeing that as a precaution both of them 
were computed. In his observation journal Bıstrup writes of these 
measurings : “Two points are sighted as Cairn VI, but it is, I suppose, 
the former which is the right one”. As it will appear, Bıstrup was 
mistaken. 
Among other things, out of regard to the interest attaching to 
the corrret determination of the position of Teufelkap, the computa- 
tions are here to be given in all details. 
The angles are measured in three sets, the mean values of 
which, in the case of the levellings with level corrections applied. is 
given below:
