THE WHITECHAPEL TRAGEDY. - The inquest into the death of Annie Chapman, the latest of the Whitechapel victims, was concluded on Wednesday. The Coroner, in his summing up, caused much sensation by surmising that the crime was attributable to a desire on the part of the perpetrator to dispose of a portion of the mutilated body to a pathological collector. He stated that he had placed the police in possession of the information he had obtained, and it was probable that some explanation would be elicited from the American authorities. The jury returned a verdict of wilful murder against some person or persons unknown.
