Especial attention should be given to the =identification= of the body (measurements, weight, build, shape of head, deformities or defects, color of hair and eyes, teeth, dental work, thumb-markings, tattoo marks, birth-marks, scars, evidences of previous diseases, occupation, clothing, etc.). In doubtful cases the body should be photographed. Roentgen-ray pictures may also be made. When only portions of a body are found the microscopic examination alone may be able to throw light upon the case and give positive evidence as to the sex, age, existence of certain physical characteristics, birth-marks, scars, disease, etc. When no conclusions can be reached a minute description of the remains should be placed in the protocol. The approximate =time of death= is to be determined with greater care in the medicolegal case (temperature of body, rigor mortis, putrefaction, dissolution, mummification, character of stomach-contents, changes in eye-balls, etc.). In the performance of the autopsy the greatest care should be taken to avoid the production of artefacts. Hammer, chisel or wedge should not be used; bones should be sawed through completely, particularly in the case of the skull and spine. Especial care should be exercised in the removal of brain and cord. Examine vertebræ in all cases when cause of death is unknown. The main-incision may begin at the chin. The mouth and pharynx should be examined for foreign-bodies before the mouth- and neck-organs are removed. These should be taken out _en masse_. Particularly in young infants is the examination of the larynx of great importance. Examine thoracic organs _in situ_ before removing them; then remove in connection with neck-organs and examine on table. Ligate cardiac end of œsophagus to prevent escape of stomach-contents. Cut œsophagus above ligature. Open pulmonary artery before lungs are sectioned. Examine abdominal organs _in situ_ before removing them. Bullet- and stab-wounds should be accurately located, traced, measured and course described. Recover missiles for use as evidence. The origin and cause of hæmorrhage must be accurately determined. Remove genital organs _en masse_ after examination _in situ_. Examine particularly contents of vagina and anus; make microscopic examination of same (semen, blood, foreign-bodies, etc.). Do not put probe, knife or shears into cavity of uterus, but open with a clean cut in the median posterior line. Examine ovaries for presence of corpus luteum.
