66 MEDICAL JURISPRUDENCE abnormally enlarged prostate. In the case of a female body, keep the mouth of an ordinary glass bottle close to the urethra, and press the bladder. Urine will pour out in the bottle, if there is any in the bladder. Uterus.—In female bodies the uterus should always be examined for its size and shape. The normal size of the organ is 3" X 2" X 1", and weight from one to one-and-a-half ounces ; but the size and weight vary consider- ably during pregnancy or when there is any tumour. The condition of its mucous membrane and the thickening of its wall should be examined after the uterus is opened longitudinally. During menstruation the mucous membrane is thickened, softer and of a darker colour, and covered with blood and detritus. In old age it becomes atrophied, and paler and denser in texture. If the uterus contains a foetus, the age of its intra-uterine life should be noted. The ovaries and Fallopian tubes should also be examined. The ovaries should be chiefly examined for corpora lutea. The vaginal canal should be opened and examined for the presence of a foreign body or marks of injury. The colour of its mucous membrane and the condition of the hymen should also be noted. Spine and Spinal Cord.—The spinal canal need not be examined unless there is any indication of disease or injury. If necessary, the body should be turned over on the face with a block beneath the thorax and an incision made along the entire length of the vertebral column extending from the occiput to the lower end of the sacrum. After reflecting the integuments, dissecting away the muscles and noting extravasation of blood in the soft tissues, the laminae should be sawn through vertically on each side and the detached portions removed, when the dura mater would be exposed. After noting its appearance, the dura mater should be opened and an examination made for the presence of haemorrhage, inflarnmation, suppuration or tumour. The cord should now be removed, laid on the table, cut transversely in several places, and examined for evidences of hemorrhages, softening and inflammatory lesions. The vertebral column should be examined for the presence of fractures or dislocations after the cord has been removed. As soon as the post-mortem examination is finished, the body should be thoroughly washed, the organs should be replaced into the cavities, and the dissected flaps should be brought in apposition and well sutured with strong twine. The body should then be covered with a cloth before it is returned to the relatives or friends so as to avoid hurting their feelings. In the absence of the relatives or friends the body should be returned to the police constable accompanying it, who should cremate or bury it according to the religious customs of the deceased, but should never throw it into a running stream or river as is often done. PRESERVATION OF VISCERA AND OTHER ARTICLES IN CASES OF SUSPECTED POISONING AND RULES FOR TRANSMITTING THEM TO THE CHEMICAL EXAMINER In fatal cases of suspected poisoning the following viscera should ordi- narily be preserved for chemical analysis in clean, wide-mouthed, white glass bottles, fitted with glass stoppers, which are issued to the Civil Surgeons from the Chemical Examiner's office, are of about one litre capacity and have serial numbers etched into the glass both of the bottles and of the stoppers: — 1. The stomach and its contents—any suspicious substance found inside the stomach should be preserved in a separate phial. 2. A portion of the liver, not less than 16 ounces in weight, or the whole liver, if it weighs less than 16 ounces.
