Bingley, when questioned by Jane, had long ago asserted his blamelessness in the affair; that, proud and repulsive as were his manners, she had never, in the whole course of their acquaintance -- an acquaintance which had latterly brought them much together, and given her a sort of intimacy with his ways -- seen any thing that betrayed him to be unprincipled or unjust -- any thing that spoke him of irreligious or immoral habits.
