[1] Notice _salvis legibus_ (Fam. 1. 4), without breaking the law;
_salva fide_ (Off. 3. 4. 44), without breaking one's word.
[2] _officium_ is used of anything which one feels bound to do, either
on moral grounds or from a desire to please others (especially those
in authority). Thus the word denotes not merely duty, sense of duty,
faithful performance of duty, submissiveness (cf. sect. xvi. 13), but
also courteous, obliging behaviour, complaisance, mark of respect.
Objectively it has the meaning of an office, service, command, e.g.
_officium maritimum_.
