He had spoken from impulse rather than from judgement, and, as is generally the case with men who do so speak, he had afterwards to acknowledge to himself that he had been imprudent.

He accused himself probably of more violence than he had really used, and was therefore unhappy; but, nevertheless, his indignation was not at rest.

He was angry with himself; but not on that account the less angry with Lady Arabella.

She was cruel, overbearing, and unreasonable; cruel in the most cruel of manners, so he thought; but not on that account was he justified in forgetting the forbearance due from a gentleman to a lady.

Mary, moreover, had owed much to the kindness of this woman, and, therefore, Dr Thorne felt that he should have forgiven much.
Thus the doctor walked about his room, much disturbed; now accusing himself for having been so angry with Lady Arabella, and then feeding his own anger by thinking of her misconduct.
The only immediate conclusion at which he resolved was this, that it was unnecessary that he should say anything to Mary on the subject of her ladyship's visit.
