Translations for propriety in French

Here are paragraphs from public domain books translated:

" 'No, no, not the sole, not the sole, my dear young lady,' he cried. 'Your duty would be, as I am sure your good sense would suggest, to obey any little commands my wife might give, provided always that they were such commands as a lady might with propriety obey. You see no difficulty, heh?'	« — Non, ce ne seront pas les seules, ma chère enfant, s’écria-t-il. Vous aurez, comme de raison, à obéir aux instructions que ma femme pourra vous donner, pourvu toutefois qu’elles soient de celles qu’une dame puisse exécuter sans manquer aux convenances. Vous n’y voyez aucune objection, je pense ?
