It appears from the regular way in which the quantities т 
and C progress, that, notwithstanding the large discrepancies 
between the amplitudes of the 10 formulae corresponding 
to the ten groups, the whole series is long enough to 
cause an almost perfect elimination of disturbing influences. 
The quantities m being the sums corresponding with about 
300 revolutions, the amplitude is about 0.06 millimetres, a 
quantity of the same order as the amplitude of the variation 
caused by lunar influence, 
By application of the formulae (9) and (10) we find: 
| В = 35.8070 days. 
| X = 1.557. 
А = 0.052 millimetres.
