Although she could not, of course, compare in outward attractions with Mlle. du Vigean, the little duchess, now in her eighteenth year, had improved greatly in appearance since her marriage, and, if not regularly pretty, she was, with her open countenance, her fine dark eyes, her beautiful complexion, and her trim figure, a decidedly pleasing personality. Moreover, she was highly intelligent, conversing well and agreeably on a number of subjects, and showing a good sense and a keenness of observation beyond her years, possessed a singularly sweet disposition, and was, notwithstanding the indifference with which her husband had treated her, sincerely attached to him.
