Nothing is perfect while something remains to be done.
Nihil potest rex nisi quod de jure potest.
The king can do nothing, unless what he can do by the law.
Nihil quod est contra rationem est licitum.
Nothing which is against reason is lawful.
Nihil quod inconveniens est, licitum est.
Nothing which is inconvenient is allowed.
Nihil tam naturale est, quam eo genere quidque dissolvere, quo colligatum est. Ideo verborum obligatio verbis tollitur; nudi consensus obligatio contrario consensu dissolvitur.
Nothing is so natural as to dissolve any thing in the way in which it was bound together. Therefore the obligation of words is taken away by words; the obligation of mere consent is dissolved by the contrary consent.
Nihil tam conveniens est naturali æquitati quam unumquodque dissolvi eo ligamine quo ligatum est.
