Nothing that the newspapers can present to their readers receives any attention except the Whitechapel murders. Important political utterances, which ordinarily would provoke general discussion, are unread and continental affairs of vital interest to England are thrust aside as of no consequence whatever. The police have adopted the theory that the letter and postal card signed "Jack the Ripper ", sent to the Central News a week ago Thursday, emanated from the actual murderer. Facsimilies of the letter and card are posted in every police station and upon every dead wall, accompanied by a paragraph begging any person recognizing the writing to communicate with General Sir Charles Warren, Chief Commissioner of the Metropolitan Police. The Central News received another communication from "Jack the Ripper" yesterday evening announcing his intention to commit more murder to-night and upon the strength of this the police have ordered every man on duty and are assisted by hundreds of amateur detectives. The reign of terror which has prevailed in the Whitechapel district during the past week still continues. and the arrival of daylight to-morrow morning will be hailed with joy by thousands of the denizens of that locality.
