On the Monday, Dr. Knox visited the Downs, where the army was assembled in review, and in the evening, as usual, he went on the Steine; but though, at both places, as he was afterwards informed, the sermon was a topic of conversation, no insult was offered, nor was any personal application made to him. Tuesday evening was the time when the offence of Sunday was to be avenged. A friend of the Doctor, having to return to London the next day, proposed that they and some of the Doctor’s family should go to the Theatre. The Doctor assented; and accordingly Mrs. Knox, Master Knox (aged about 14), and Miss Knox (12), accompanied them, the piece to be represented being the _Agreeable Surprise_. They occupied the right-hand side box, next to the stage box, where the Prince of Wales usually sat: but he was not there that evening. Soon after the curtain drew up, a few officers entered the opposite stage-box. But they had not been there five minutes, before their whole attention seemed fixed on the box where the Doctor and his party were seated. Other officers and several elderly ladies soon appeared in the same box; and they looked at the Doctor in a pointed manner, and then seemed to deliberate. Their attention appeared to be engrossed by the consultation, and they seldom turned to the players on the stage. There were several other officers interspersed in other boxes. Messages were sent to some of them, and they removed into the stage box. A man, whose looks were choleric, and who sat in the same box and on the same seat with Doctor Knox, was sent for, and he left his hat behind him, probably intending to return when he should be excluded. They frequently went in and out, and appeared extremely busy and anxious in concerting the plan of operations. This continued during the whole of the play. The children observed it, and told their father that they suspected some insult. Between the play and the entertainment, the following note, directed to the Doctor, was handed from behind them, to Mrs. Knox, who gave it to her husband. The son had seen one of the officers writing; and there is no doubt but he was composing this note, which was sent without a name, and couched as follows:— “Your Discourse last Sunday was so offensive, that the gentlemen of this Theatre desire you will quit it immediately.”
