Chief of Police Crowley has lately been in correspondence with the officials of Scotland Yard, London, regarding Dr. Tumblety, who is at present under arrest on suspicion of being implicated in the Whitechapel murders. On the 19th inst. Chief Crowley sent a dispatch to the London detectives informing them that he could furnish specimens of Tumblety's hand-writing, and yesterday received the following answer from the Scotland Yard detectives:

Thanks. Send writing and all details you can in relation to him. ANDERSON.

Chief Crowley in pursuing his investigations discovered that the Hibernia Bank, which he left there when he disappeared from the city, and which has never been drawn upon since. Mr. Smyth of that institution says that he first met Tumblety in Toronto, where he was practicing medicine in July, 1858. He next met him in this city at the Occidental Hotel in March or April, 1870. Tumblety rented an office at 20 Montgomery street where he remained until September, 1870, and then disappeared as suddenly as he came, and in 1871 the Doctor turned up in New York.

It is the belief of Chief Crowley that people in this city have confounded Dr. Tumblety with Dr. Stanley. The latter had been a surgeon in the British Army, and came to this country from Australia. He was a large, distinguished-looking man, and had his office with Dr. Sharkey, on Washington street, and was a well-known character around the Snug Saloon, under Maguire's Opera House, on Washington street. Stanley was in the habit of dressing in a peculiar manner and always wore top boots and was followed by two greyhounds whereas those who knew Tumblety during his short residence in this city say he never was the owner of any dogs during his stay. Finally Stanley did something contrary to the law and while the present Chief of Police and the late Samuel Harding were looking for him he managed to slip out of town. At the time the officers thought that he had returned to Australia, but later they learned that he had gone to New York. Owing to the short time that Tumblety resided in this city, Chief Crowley thinks it improbable that people could have become well-acquainted with his actions.
