54. In cases of suspected drowning, the inspectors will observe particularly whether grass, mud, or other objects be clutched by the hands, or contained under the nails; whether the tongue be protruded or not between the teeth; state of the penis; whether any fluid, froth, or foreign substances be contained in the mouth, nostrils, trachea, or bronchial ramifications; whether the stomach contains much water; whether the blood in the great vessels be fluid. Careful pressure should be made upon the lungs; any fluid contained in them in thus forced into the bronchial tubes and trachea, and its nature observed. When water with particles of vegetable matter or mud is found within the body, these must be compared with what may exist in the water in which the body was discovered, and should be preserved for further scientific investigation, if requisite. Marks of injuries must be compared diligently with objects both in the water and on the banks near it, and especial attention given to the question--whether any observed injuries had been sustained by the body before or after death. 55. In cases of suspected death by hanging, strangling, or smothering, it is important to attend particularly to the state of the face as to lividity, compared with the rest of the body; the state of the conjunctiva of the eyes as to vascularity; of the tongue as to position; of the throat, chin, and lips as to marks of the nails, scratches, ruffling of the scarf-skin, or small contusions; the state of the blood as to colour and fluidity; the state of the heart as regards the amount of blood in its several cavities; the state of the trunk and branches of the vena cava in the abdomen as regards distension with blood; and the state of the lungs as regards congestion, rupture of any of the air cells, and small ecchymoses under the pleura, or the pericardium. The mark of a cord or other ligature round the neck must be attentively examined; and here it requires to be mentioned that the mark is often not distinct till seven or eight hours after death, and that it is seldom a dark livid mark, as is very commonly supposed, but a pale greenish-brown streak, presenting no ecchymosis, but the thinnest possible line of bright redness at each edge, where it is conterminous with the sound skin. Nevertheless, effusions of blood and lacerations should be also looked for under and around the mark, in the skin, cellular tissue, muscles, cartilages, and lining membrane of the larynx and trachea. Accessory injuries on other parts of the body, more especially on the chest, back, and arms, must also be looked for, as likewise the appearance of blood having flowed from the nostrils or ears, and the discharge of fæces, urine or semen. In cases where death may be due to the emanations from burning fuel or other poisonous vapours, a small phial should be filled with the fresh blood, and securely corked for further investigation, if requisite.
