Upon his arrival at the morgue, John F. Scanlan pried open the mouth of the corpse with a pencil, and Dr. Lewis immediately recognized his handiwork in the gold filling of some of the upper teeth. It was a remarkable fact, moreover, that in a lower jaw plate that he had made for the physician he had placed several teeth peculiar to themselves, and known to the profession as "crown sunk." He had done this something in the line of an experiment. This identical plate was taken from the mouth of the dead man, while, to make the proof still more positive, the cast of Dr. Cronin's mouth, taken for the purpose of making the plate, was found to fit the mouth of the corpse to a fraction. [Illustration: SCANLAN AND CONKLIN IDENTIFYING THE BODY.] After Dr. Lewis came Cronin's tailor, Joseph J. O'Keefe, and who, upon making tests, found that the measurements of those portions of the body that had not perceptibly increased in size were identical with the figures in the order book kept by his cutter. John Buck, the barber who had counted Dr. Cronin among his customers for over a year, recognized the shape of the head and the texture of the hair; and immediately after, Dr. John R. Brandt, President of the staff of the Cook County Hospital, and who had been comparing the dead man's hair with the lock of hair found in the trunk three weeks before, declared that they had come from the same head. In this he was corroborated by Dr. Ruthford. T. T. Conklin arrived at the station at 8 o'clock. He was taken down-stairs and looked long and earnestly at the bloated corpse. "It is the body of Dr. Cronin," said Conklin, his eyes filling with tears. "I have known him for twenty years and cannot be mistaken. I have been in swimming with him and know him better than any man living. There is no chance for a mistake. I don't like to say 'I told you so,' but this substantiates what I have said from the start. Dr. Cronin was murdered, and if the police had done their duty, instead of believing the lies invented by Dr. Cronin's enemies, the murderers would have been captured before this time."
