As there were no tables of the quantitues [1], [2] and [3] north 
of 72° it was necessary first to compute the auxiliary table below of 
the quantities mentioned, where M and N are expressed in metres.

As the geodetists of the Germaniaexpedition had not themselves 
computed the geographical co-ordinates of their triangulation stations, 
I have also had to perform this computation in the case of the 
stations on which the position of Haystack was dependent. The 
necessary data are to be found in “Die zweite deutsche Nordpolfahrt, 
Bd. II, Wissenschaftliche Ergebnisse”. The results are presented in 
the table given below, and are here given in tenths of seconds. This 
accuracy, which in this case corresponds to a table of 5 decimals, 
is naturally only an accuracy of computation. which aims at avoiding 
an accumulation of errors in calculation. 
The stations are given in the order of succession in which they 
were computed.
