JACK THE_ RIPPER.Alleged Discovery of Important Glue*—On the Murderer's Track.A RELIGIOUS MANIAC.Eight Bets of Disguises—Mysterious Movements—He Haunted WhitsohapeLThere is one man in London who knows more about “jack the Ripper than all the policemen and detectives in the metropolis, says the New York Herald. For the present, for obvious prudential reasons, the name and address of this person cannot be disclosed. This gentleman, who sufficient material and circumstantial evidence to hang ten “Jack the Rippers,” is in secret communication with Dr. Forbes Winslow, aad a reporter is in the confidence of the lunacy specialist.The invisibility in which “ Jack ” is enveloped is growing thinner, and to those who have followed bis murderous movements it is certain that Nemesis is closing upon him, and that within a period may be measured his capture and identity will be effected.ALLEGED IDENTIFICATION.The doctor is on the murderer’s track. He possesses tangible proof of identity, and is convinced that he could eff ect his arrest in a week. He means to act upon the clue supplied to him, and he does not intend to call in the assistance of the police. He has done that before, and has formed such an opinion of their incompetency and the road jealousy which excites them that in future operations be would prefer to do without them.Here is his remarkable story: A gentlemanwhom he had previously known called upon him In reference to the Whitechapel murders. Jack the Ripper lodged in this person's house. He knew that it was “ Jack the Ripper ” by putting two and two circumstances together. Suspicions were first aroused by the lodger coming home about four o'clock one morning. He had expected to find everybody in bed, and to be able to get to his room unobserved. To his surprise, bis landlord, Dr. Winslow s informant, had been kept up waiting for bis wife, who was on a visit to some friends The lodger was excited and incoherent in his talk. He said he had been having a rough time, that he had been assaulted, and had his watch stolen, and he gave the tmwm of a police station where he had laid a complaint- Upon inquiries at the polioe-station this story was found to be entirely devoid of foundation. He had made no complaint, and the police had no knowledge of a street disturbance. The man's shirt and underclothing were found flanging over chairs They had been washed and been put out to dry. He was in the habit of ttikmg about the women of the street, and wrote •• long rigmaroles ” about them. His writing in pinntg particulars resembled that of the letters sent to the police purporting to come from Jack the Ripper.” He had a wardrobe as extensive as a duke’s It included eight suits of cknbes. sight pairs of boots, and eight hats The man can sr—fr several languages, and when he went out he Strays carried a black bag. He was apparently Well off, and never wore the same hat on two successive occasions When he left his lodgings a quantity of bows, feathers, and flowers and other articles which had belonged to the lower class of tound in bis room. He also leftfrfthmd him three pairs of boots and three pairs of goloshes one of each of which is now in the possession of Doctor Winslow. The boots are ordinary leather lace-up boom with thin soles. The galoshes have indiarubber bottoms and American moth uppers, end are bespattered with Mood.Upon this and other material, which chnnot now be described, a most important clue is thought to bave been discovered. They will, however, form the of a vigorous prosecution, which wffl be set in motion to-morrow.FUBTHJCJl CONFIRMATION.Dr. Winslow said to a reporter yesterday:—The gentleman who lodged “ Jack the Ripper ** bos seen postcards addressed to him which tendetL to greatly strengthen his suspicion. He has never^ entirely tost sight of the murderer, and has never given np hope of securing him. He celled upon me a few days ago and said:•• Well, doctor, my story is more than ever coo-Armed in the investigations I have been making, aad there is going to be another murder committed thfcweek.”I mid, “Well, bow do you know? aad be replied, ** I have teen one of the women in Whitechapel, with whom the man I suspect to be the murderer has been in communication. He offered the woman a sovereign and then made it two aovnreigns to go down a court, but she refmed.” At that momenta man came out of the coart, aad as aoon as my suspect saw him he stm ply raised hb hat to the woman and made himself scarce. This same man was seen to write on the wall: ‘ I will commit yiwiiw murder shortly.* **I said, “Had we not better communicate with the police?** and my informant replied, “I ham taken a policeman np to this very arch and shown him the writing on the walL”What did he do ? X asked. Oh! was the teply, “be simply rnbbed it out again, and said • It is not on my beat.*M From my informant's general description of the man, and the history of the case, I hare not the aWhtast doubt that he is the Whitechapel murdrrw. He is a linguist, aad is under strong “ ‘ delusions with reference to thela the streets. He was constantly taHdag to bimerlf, and he had a pistol which he used to keep on the sideboard in his room. Whea anyone entered he would rush across the room, and put bis bade against the sideboard, and with his hands him would feel for the revolver. I have Seen more letters, and more people about this, and other Whitechapel murders than the Home Office, •nd I bave not the slightest doubt that “ Jack the Ripper” is a lunatic, I don't think anybody can bave any doubt about that.
