It appears from these resulto that at Batavia, «d 
disturbing influences are very small, the error commi 
calculating a double periodical variation, the amplitude of 
is about 0.05 millimetres, does not exceed a three ! 
part of the adopted unit of time, when a number 
7400 observations is taken into account. The error e Ч 
pected, when only a five-monthly series is employed, ыг 
0.005 hours; the calculated amplitude is practically е"

the error of the epoch may amount to 25 degrees, in
