London, March 9.
The fact has developed that Scotland Yard detectives have discovered that the famous Jack the Ripper is an inmate of Dartmoor insane asylum, having been sent there shortly after the last of the Whitechapel atrocities. The fact has been kept a profound secret, but is now guardedly admitted.

The Scotland Yard authorities have possession of the knife, which is of Chinese make, with which the Whitechapel murders were committed. They are also familiar with his movements during the intervals between the murders, and have been able to trace him to the asylum after the last crime. Although pronounced incurably insane by the asylum physicians, the man has a clear recollection of the past and all his conversations and remarks have reference to his crimes in the east end. Correspondence has passed between the government criminal department and the asylum authorities relative to the murderer's condition, and as to whether now or at any time in the near future he is or will be likely to be sufficiently rational to be placed on trial.

The result of these inquiries has not yet been disclosed.
