guillotine, imported, it is said, from Halifax, by the Earl of Morton, while regent, who was himself the first that suffered by it. The printed account of this beautiful murderess contains a pathetic narrative of the exertions of the worthy clergyman (its author) to bring her to repentance. At first, his ghostly comfort was very ill received, and she returned with taunts and derision his exhortations to penitence. But this humour only lasted while she had hopes of obtaining pardon through the interest of her family. When these vanished, it was no longer difficult to bring her, in all human appearance, to a just sense of her condition; her thoughts were easily directed towards heaven, so soon as she saw there was no comfort upon earth. The pride of Lady Warriston's parents suggested a petition that she might be executed betwixt five and six in the morning; but both the clergyman and magistrates seem to have consented unwillingly to this arrangement. The clergyman was particularly offended that the display of her penitence should not be as public as that of her guilt had been, and we may forgive the good man if there was any slight regret for a diminished display of his own success, as a religious assistant, mixed with this avowed dissatisfaction.--_Quarterly Rev._ * * * * * SOUND. The difficulty of transmitting sounds to a great distance arises from the sound spreading and losing itself in the surrounding air; so that if we could confine it on one side, as along a well--on two sides, as in a narrow street--or on all sides, as in a tube or pipe--we should be able to convey it to great distances. In the cast-iron water-pipe of Paris, which formed a continuous tube with only two bendings near its middle, the lowest whisper at one end was distinctly heard at the other, through a distance of 3,120 feet. A pistol fired at one end actually blew out a candle at the other end, and drove out light substances with great violence. Hence we see the operation of speaking tubes which pass from one part of a building to another, and of the new kind of bell which is formed of a wooden or tin tube, with a small piston at each end. By pushing in one piston, the air in the tube conveys the effect to the piston at the other end, which strikes against the bell--this piston being, as it were, the clapper on the outside of the bell. The intensity of confined sounds is finely exhibited at Carisbrook Castle, in the Isle of Wight. There is here a well 210 feet deep, of twelve feet in diameter, and lined with smooth masonry; and when a pin is dropped into it, the sound of its striking the surface of the water is distinctly heard.--_Ibid._ * * * * * ECHOES.
