This is at the end of the 11th paragraph before the end of the last chapter of the novel, and it describes Robert and Lucy's domestic felicity:

"They settled in town, received very liberal assistance from Mrs. Ferrars, were on the best terms imaginable with the Dashwoods, and setting aside the jealousies and ill-will continually subsisting between Fanny and Lucy, in which their husbands of course took a part, as well as the frequent domestic disagreements between Robert and Lucy themselves, nothing could exceed the harmony in which they all lived together."
