Mr. BEAMAN, the surgeon, who had minutely examined the body after death, was again called forward and re-sworn. He repeated his former opinion, founded on the _post mortem_ examination of the body, that death had been produced by extravasation of blood in the spinal canal, an effect, which must have been produced by violence on the back of the neck. The violence might have been produced by a blow from a round stick or bludgeon, or even by the wrist of a strong man's arm. It was barely possible, certainly, that the injury might have been occasioned by a fall down stairs. Mr. PARTRIDGE, demonstrator of anatomy at the King's College, agreed with Mr. Beaman in every particular, in regard to the causes which had produced death. Mr. MINSHULL.--Is it your opinion, then, that the boy came to his death by violence--in short, that he was murdered? Mr. PARTRIDGE.--I certainly do believe that the death of the deceased was effected by violence. Mr. MINSHULL.--Is it from the state of the neck merely, or from other appearances, that you have come to that conclusion? Mr. PARTRIDGE.--I believe the immediate cause of death to have been a blow on the back of the neck by some blunt instrument, but I judge of the violence which must have been used, from other circumstances, namely, the freshness of the body, the rigidity of the limbs, the swollen state of the face, the bloodshot eyes, and their perfect freshness. In answer to a question by Mr. Swabey, the witness said that the superficial dirt on the thighs, belly and chest of the deceased, might have been done designedly or by accident. Trailing the body along a dirty floor would leave such marks. Mr. MINSHULL.--Could the deceased have committed suicide? WITNESS.--It is just barely possible that a person might inflict a blow on the back of his own neck which would cause death. It was, however, exceedingly improbable, and almost impossible. Mr. BEAMAN said, he could not see how suicide could be at all effected in that way. A man might certainly break the back part of his neck, by flinging himself from a height on a bar, but he could not, in his opinion, inflict the same injury on himself, by means of a stick or bludgeon. Mr. THOMAS MILLS, a dentist, residing on Newington Causeway, having been sworn, stated, that on Saturday morning, the 5th of November last, the prisoner May came to his shop and offered him a set of teeth for sale, for which he asked a guinea. Witness observed that one of the front teeth was chipped, and said that it did not belong to the set: upon which May said, 'Upon my soul to God, they all belonged to one head, and that not long since, and that the body had never been buried.' He ultimately agreed to take twelve shillings for the teeth. Mr. CORDER asked the witness, if he had not observed something peculiar about the teeth.
