In ch.13, we are told that after visiting with Miss Tilney, "The general attended [Catherine] himself to the street–door, saying everything gallant as they went downstairs, admiring the elasticity of her walk, which corresponded exactly with the spirit of her dancing, and making her one of the most graceful bows she had ever beheld, when they parted."
That business about "admiring the elasticity of her walk" strikes me as a little odd. To me, it sounds rather like an older man telling a teenager what a great figure she has, but Catherine doesn't seem embarrassed, so maybe it's just me, and his compliment is perfectly acceptable. In any case, it seems like a clue that JA's contemporaries could get more personal with compliments about someone's physical assets than we might imagine! What do others think - is it just me?
