Those were not the best possible dispositions in which Allan could find her.

He had not reckoned upon these better influences; he had not thought that when she came to contrast his behavior with that of others she would see how deficient in all honor and manliness it had been; he trusted to the glamor of love, and behold! there had been no love on her part; nothing but gratified vanity.
