Pennant speaks of Surgeons' Hall as a handsome building, ornamented with Ionic pilasters, and with a double flight of steps to the first floor. Beneath is a door for the admission of the bodies of murderers and other felons. There were other public dissecting rooms for criminals. One was attached to Hicks' Hall, the Clerkenwell Sessions' House, built out of monies provided by Sir Baptist Hicks, a wealthy alderman of the reign of James I. Persons were still living in 1855 who had witnessed dissections at Hicks' Hall, and "whom the horrid scene, with the additional effect of some noted criminals hanging on the walls, drove out again sick and faint, as we have heard some relate, and with pale and terrified features, to get a breath of air." The dissection of executed criminals was abolished soon after the discovery of the crime of burking, with the idea that ignominy would no longer attach to an operation which ceased to be compulsory for the most degraded beings; and that executors or persons having lawful possession of the bodies of people who had died friendless, would voluntarily surrender them for the advancement of medical science. Another brutal practice had nearly disappeared about the time of the abolition of dissection. This was the public exhibition of the body, as was done in the case of Mrs. Phipoe, the murderess, who was executed in front of Newgate in 1798, and her body publicly exhibited in a place built for the purpose in the Old Bailey. About this time we find that the bodies of two murderers, Clench and Mackay, "were publicly exposed in a stable in Little Bridge Street, near Apothecaries' Hall, Surgeons' Hall being let to the lieutenancy of the county for the accommodation of the militia." In 1811 Williams, who murdered the Marrs in Ratcliffe Highway, having committed suicide in gaol to escape hanging, it was determined that a public exhibition should be made of the body through the neighbourhood which had been the scene of the monster's crimes. A long procession was formed, headed by constables, who cleared the way with their staves. Then came the newly-formed horse patrol, with drawn cutlasses, parish officers, peace officers, the high constable of the county of Middlesex on horseback, and then the body of Williams, "extended at full length on an inclined platform erected on the cart, about four feet high at the head, and gradually sloping towards the horse, giving a full view of the body, which was dressed in blue trousers and a blue-and-white striped waistcoat, but without a coat, as when found in the cell. On the left side of the head the fatal mall, and on the right the ripping chisel, with which the murders had been committed, were exposed to view. The countenance of Williams was ghastly in the extreme, and the whole had an appearance too horrible for description." The procession traversed Ratcliffe twice, halting for a quarter of an hour in front of the victims' dwelling, and was
