Boston, Mass., Nov 21 - (Special.) - Dr. Kumblety, as the man arrested in London on suspicion of being connected with the Whitechapel murders calls himself, is well known in Boston. Said one today who knew the doctor: "The fellow's name is Tumblety. About 33 years ago there came to Boston from the Canadian provinces a man who engaged an office in the Horticultural Building on Tremont street. He was a quack doctor, and during his stay in Boston used considerable ground gentian. I remember this fact for I sold him quite a large amount of goods from time to time. When I knew him I was a boy in my teens. His name was Dr. Tumblety. I remember him as a rather tall, fine-appearing individual. He was a most peculiar person. He wore, pinned to his vest, several large medals which he said had been awarded him in various colleges where he had studied. He liked to display heavy jewelry. He had every appearance as a quack doctor. I should say he was about 30 years old when I knew him. He liked the slums, notwithstanding the fact that he always had plenty of money, and could have entered, if he had been inclined, into good society."
