An inspection of the last column of Table b shows that it is no easy 
matter to deduce corrections to the predicted times. It is evident that the 
correction cannot be considered as constant for any length of time; it was 
therefore necessary to make some combination of the results surrounding the 
Fram-observations, but in making such combinations some arbitrariness is 
scarcely avoidable. In the few cases where the eclipses observed on board 
had also been observed elsewhere the deduced correction could, for some of 
them, be applied without alteration, but for others a combination was pre- 
ferred when sufficient surrounding material was at hand. The corrections 
deduced from such combinations were often rounded to the nearest 5 or 10 
seconds,
