famous Burking case. A woman was struck down to a sitting posture. Burke then threw himself on her, kept her down by the weight of his body, covered her mouth and nose with one hand and placed his other hand under the chin for ten to fifteen minutes, till she died. Necroscopy showed a severing of the posterior ligamentous connections of the third and fourth cervical vertebræ, with blood in spinal canal but not under the dura mater; cord not injured. Christison made experiments to ascertain if the injury to spine had been made during life.
