Since these means are all nearly equal to or smaller than their 
m.e., we may conclude that for observer G. no influence of the 
declination on the time of transit exists. 
The explanation of the effect may perhaps be sought in the fact, 
that the observers H. and Z. endeavour to make the contact of the 
signal key coincide with the moment that the star passes a thread, 
which is in agreement with their own statement as to their method 
of registering, while the observer G. begins with the movement of 
registering at the moment that he observes the star to be bisected 
by a thread.
