But to return to the Sparrows; there have been so many Flights of them let loose in this Opera, that it is feared the House will never get rid of them; and that in other Plays, they may make their Entrance in very wrong and improper Scenes, so as to be seen flying in a Lady's Bed-Chamber, or perching upon a King's Throne; besides the Inconveniences which the Heads of the Audience may sometimes suffer from them. I am credibly informed, that there was once a Design of casting into an Opera the Story of _Whittington_ and his Cat, and that in order to it, there had been got together a great Quantity of Mice; but Mr. _Rich_, the Proprietor of the Play-House, very prudently considered that it would be impossible for the Cat to kill them all, and that consequently the Princes of his Stage might be as much infested with Mice, as the Prince of the Island was before the Cat's arrival upon it; for which Reason he would not permit it to be Acted in his House.

In Act 5 the foolish Sir Martin appears at a window with a lute, as if playing and singing to Millicent, his mistress, while his man Warner plays and sings. Absorbed in looking at the lady, Sir Martin foolishly goes on opening and shutting his mouth and fumbling on the lute after the man's song, a version of Voiture's 'L'Amour sous sa Loi', is done. To which Millicent says,
