Mr. THOMAS, the Superintendent of the Police, then came forward, and having been sworn, said, that he charged the prisoners at the bar with the suspicion of having been concerned in the murder of a boy, aged about fourteen years, whose name he was unable to state. It was not in his power, at that time, to offer any direct evidence against the prisoners, but a gentleman, connected with the surgical department of the King's College, to whom the body had been offered for sale, was then present, and would state the circumstances which caused his suspicions, and induced him to cause the apprehension of the prisoners. Mr. RICHARD PARTRIDGE, of Lancaster Place, was then sworn, and stated, that he was demonstrator of anatomy at the King's College, and had seen the body in question, which the prisoners had brought that day to the College. The body was that of a boy, apparently about fourteen years of age; and from the suspicious appearances which it presented, he was induced to believe that death had been produced by violence. Mr. MINSHULL.--Be good enough to state upon what grounds you came to that resolution. Mr. PARTRIDGE.--The body appeared to me to be unusually fresh, much more so than bodies generally are, that are used for dissection; the face was much discoloured, and blood appeared to have been forced through the lips and eyes; the upper part of the breast-bone had the appearance as if it had been driven in, and there was a wound on the left temple, about an inch in length. The teeth were all extracted, and blood was flowing from the mouth. Mr. MINSHULL.--Had the body, in your opinion, ever been buried? Mr. PARTRIDGE.--I should say not; and I judge so from the rigidity of the limbs and muscles. Mr. MINSHULL.--From all that you have observed, can you undertake to say, that the several marks of violence on the body, or any one injury in particular, occasioned death? Mr. PARTRIDGE.--I have not as yet sufficiently examined the body, and am, therefore, not prepared to answer that question. The pressure on the breast-bone might have occasioned death, but I cannot, at present, say that it did, as I do not know the extent of the injury. Mr. MINSHULL.--Do I understand you to mean, that, to the best of your belief, the body of the deceased had never been buried, and that, as far as you have as yet been able to form a judgment, the boy did not die a natural death? Mr. PARTRIDGE replied, that such was his present opinion. Mr. THOMAS here observed, that a medical gentleman, of the name of Edwards, who had seen the body, stated his belief that death had taken place within the last twelve hours. That gentleman was not present, but he (Mr. Thomas) could send for him. Mr. MINSHULL said, that he would probably require his attendance, but it was not necessary at present. The magistrate then asked what evidence there was to connect the prisoners with the possession of the body.
