=Violence.= Wounds must be minutely described as to character, degree of laceration, contusion, extravasation, damage to tissues, direction of force, character of instrument, means and method of infliction, path of projectile or stab-wound, etc. Postmortem changes and injuries must be differentiated, as must be also antemortem and postmortem lesions, primary and secondary effects of the injury, effects of injury and pre-existing diseases. Intracranial hæmorrhages must be carefully differentiated with respect to causation by violence or disease. Effects of _contrecoup_ must be borne in mind. The presence of other marks of trauma, the exclusion of disease, the location of the clot, the age of the clot, the age of the patient, etc., are some of the factors to be considered. In young people without alcoholic history or syphilis intracerebral hæmorrhages without signs of violence are rare. When associated with fractured skull they are usually regarded as due to the trauma. CHAPTER XV. THE RESTORATION OF THE BODY. When the autopsy is finished the body-cavities are cleansed and then thoroughly dried. No blood, stomach- or intestinal-contents should be left in the cadaver. All bleeding or dripping parts should be tightly secured; the anus and vulva should be tightly stitched, and the penis ligated. If necessary, the organs are then cleansed and returned to the body, as nearly as possible to their normal positions, although the brain, because of the difficulty of getting it back into the skull-cap, is usually put into the thoracic cavity. When several autopsies are done at the same time, care should be taken not to mix the organs. The undertaker should always be aided in his work; and, if he so desires, an embalming powder or fluid may now be sprinkled or poured into the cavities.
