New York, April 29.
The police continue their hunt for Jack the Ripper, and are sifting the slums for the murderer. Mary Roscoe, an abandoned woman, has been committed as a witness in the case. Two arrests were made last night, the prisoners being a man and a woman.

The man was closeted with the detectives and captain for a long time and then locked up. No description of the man or anything about him could be learned from the police. The officers also had a long conference with the woman before she was put in a cell.
