228 I. P. KocH. 
In the following the computation of the levelling at Station I is 
given as an example, whereas in the case of the other stations for 
which the levelling was computed only the necessary data for the 
undertaking of the computation have been given, as well as the 
results of the latter. The zenith distances are given in whole seconds, 
as found by the computation in the observation journal (see pp. 206—207). 
It is, however, obvious that whole minutes would in most case have 
supplied sufficient accuracy.
