MISCELLANEOUS. EXTRAORDINARY OUTRAGE. - An extraordinary outrage (say the "Liverpool Post") was committed on Tuesday at a village called Harwood, near Bolton. A boy named JAMES ROSCOW, aged sixteen years, employed at Firwood Bleachworks, was proceeding to his work, about six o'clock, and upon crossing the moor, a strange man called out to him to come back. The boy, however, feeling afraid, ran off, but he was followed and overtaken by the man, who threw him to the ground, and drawing a knife out of his waistcoat pocket, cut the boy's throat, inflicting a wound two inches in length. Struggling out of the fellow's clutches, the boy again ran off, the man shouting to him, "Come back, and I'll put a rag on." The boy was conveyed to the house of his father, REUBEN ROSCOW, stone finisher, Harwood, where the wound was stitched by MR. SMITH, surgeon. Fatal consequences are not anticipated. The man has not yet been apprehended.
