In this communication the attention is payed to the influence of mass
loss in large timescales on binary star orbits, in particular on their
eccentricities.
The known Eddington-Jeans law does not predict the eccentricity's secular
increase despite the cases of periodical variations with large oscillations
may exist.
The common law proposed by Chiara when the secular increase of
eccentricity is producing due to mass loss variation inversely proportional
to distance square is also considered.
