Record the height and if possible the weight. Note the sex, the probable age, nutrition, and cleanliness or otherwise. Examine all wounds, bruises, and describe them carefully, and marks, _e.g._ strangulation or throttling. Examine the hands carefully and describe their peculiarities, also the colour of hair and eyes. Examine all the apertures of the body for foreign bodies, or abnormal conditions, and, in females, record carefully the condition of the external genitalia and the presence or absence of the hymen. Although a more detailed account of the method of carrying out post-mortem examinations is given later on, it will not be out of place here to point out briefly the steps of examination. I would again emphasize the importance of making a thorough and complete internal examination, leaving no organ unexamined. If there be no call for special examination of the thorax or abdomen first, commence with the examination of the surface of the brain, then proceed downwards. Note the direction of any wounds and their depth. Examine all organs for morbid changes, and in females, the vagina and uterus. Examine the larynx and œsophagus. Remove injured bones and examine joints. Remove the spinal cord. Always remember to note the contents of the stomach and bladder in reference to the period at which death may have occurred. Weigh all organs. Always remember the probability of poisoning, and make your examination accordingly. All fragments or injured parts of a body or its organs should be preserved, and photographs taken of them. It is better for two medical men to conduct the examination together. Do not make the examination without an order from the coroner. A medical man who is alleged as implicated in the cause of death should not be present. Identification of the dead may present special difficulties where mutilation of the body has taken place, or where the body has been severely burnt, or is disfigured as in cases of explosions or advanced putrefaction. In such cases, fragments of clothes, ornaments, and dental work may afford valuable evidence. Occupation Marks.--As an aid to identification, it is important to remember that certain trades leave marks by which those engaged in them may be identified. Thus, in shoemakers there may be more or less depression of the lower portion of the sternum, due to constant pressure of the last against the bone. Tailors work sitting, with the legs crossed and the body bent forward. The body is thus cramped, and the abdomen drawn in, and the thorax projects over it, due to the manner of sitting. They frequently have a soft red tumour on the external malleolus. A like tumour, but not so large, may also be found on the external edge of the foot, and a corn on the little toe. Photographers have their fingers blackened by nitrate of silver, pyrogallic acid and other developers, or stained yellow with bichromate of potash.
