>From Jackson's Oxford Journal, Saturday, November 14, 1807; Issue 2846. OFFENCE. - During the rejoicings on Thursday evening last, the Anniversary of the Gunpowder Plot, the following dreadful occurrence took place in the city of Bristol. Sarah OSBOURNE , a fine girl, about 14 years of age, the niece of Mr. WEBB , Cooper, of Sims's Alley, was standing at a shop in the Horse Fair, when some person discharged a musket behind the watch house, on the opposite side of the way, and shot her through the head. The ball penetrated the windows of the house opposite to which she stood, broke a picture to pieces which hung against the wall, and rebounded. She expired at ten o'clock on Friday morning. On Saturday a Coroner's inquest was held on the body, when Mr. WILLIAMS stated, that he saw two men about 20 yards from the watch house, one of whom carried a gun, and the other a pistol; that the person who carried the gun was a tall man, with a soldier's great coat. Witness saw him present the gun towards the watch house, and fire it off, but thinks it impossible he saw the girl at the time, or that he had an intention of killing any body. Several other witnesses confirmed this testimony. The Jury returned a verdict of - Manslaughter against some person or persons unknown.
