The practice of boys throwing stones at each other in the streets, ought to be noticed by the Police, as it is often productive of severe accidents to persons passing at the time.—a verdict of manslaughter has been returned at Wolverhampton, against a boy named Murray, for having caused the death of another boy named William Wharton, by throwing a large stone at him and striking him a violent blow on the side, between the hip and the ribs. The below has produced a large internal abscess, and has also ruptured the kidney.—last week, at Petersfield, a lad named to Booker, was killed by a blow on the head from a brick-bat, thrown at him in the play by another.
