"Lady Mary, perceiving how things were like to go, did what I was always afraid of, and could not possibly prevent: she went in rage to her poor sister, and so swaggered and frightened her, that she relapsed. While she was about that fine piece of work, Lord Erskine happened to go to Lady Mar's; and in his presence Lady Mary continued to this purpose with her sister: 'Can you pretend to be well? Don't you know you are still mad? You shan't get out of my custody; and if Lord Grange and his confederates bring you before Lord Chancellor, I'll make you, in open court, in presence of the world, lay your hand on the Gospel, and swear by Almighty God, whether you can say you are yet well. Your salvation shall be at stake; for, remember, perjury infers damnation--your eternal damnation.' So soon as I was informed of this, I assured my lady (and so did others,) that in law no such oath could be put to, her, and that Lady Mary had only said so to fright her.

And Lady Mary, having thus dismounted her came again and coaxed her, and (as I found by diverse instances) strove to give her bad impressions of her family, and everybody but Lady Mary's sweet self. Yet next day Lady Mar went and dined at Mr Baillie's in town, and there saw a deal of company, and behaved very well.

She was behaving decently, but with the gravity of one that is wearied and tired. Mr Baillie himself, and the other gentlemen and ladies, (a great many being in the next room,) now and then joined us, and she seemed not in anything discomposed, till the conversation turned on her sister's late insult, which, it was visible, gave a shock to her, and disconcerted her; and when Lady Murray and I went home with her to Knightsbridge, she was so dumpish that she scarcely said one word. When I went to her next day, I saw how strongly Lady Mary's physic wrought, and dissipated her poor returning senses. She had before urged me earnestly to proceed faster than was fit, to get her before the chancellor, and do
