In cases of suspected poisoning, the utmost precautions are to be used in making the autopsy. All the viscera are to be carefully examined, and the stomach and intestines, with their contents, are to be removed in the manner already described. They are then to be opened, examined in separate vessels, either entirely new, or thoroughly cleansed immediately before being made use of. After a careful examination, they are to be placed in perfectly clean or new glass jars, without the addition of any foreign substance; the jars are then to be securely corked and labelled, and handed over to the chemist for analysis. Should the jars have to remain any time in the hands of the physician, they are to be kept under lock and key, in some place to which none but himself has access. Portions of other organs, especially of the liver, spleen, kidneys and brain, should also be preserved with the same care for future analysis. The results of the examination are to be taken down on the spot, by an assistant, in ink, and after having been read through by the physician at the close of the examination, are to be signed by him. All these precautions will be found of great value, in saving from innumerable petty annoyances, at the hands of the “learned members of the bar,” if the case should be brought before court. In the _external_ inspection of the body, we should notice: 1. _The Sex._ Even after the external parts of generation have been completely destroyed, the sex may still be ascertained by a reference to the growth of hair around these parts. A circumscribed arc of hair on the _mons veneris_, is distinctive of the female, while its prolongation, however slight, from this point towards the umbilicus, marks the male. 2. _The Age._ In the case of known bodies this is not of any importance, in unknown bodies it is, however, necessary. The physician can only conjecture from appearances, which, even in the living body, are very deceptive, and he will do well, therefore, to allow tolerably wide limits to this conjecture. 3. _The Size._ The length of the body must be ascertained by actual measurement in a straight line, from the crown of the head to the sole of the heel. 4. _The General Condition of the Body._ Lean or fat, etc. 5. _Color and Condition of the Hair._ 6. _Color of the Eyes_, if still recognizable. 7. _Number and Condition of the Teeth._ In the case of unknown bodies, an accurate description is always advisable, with a view to future identification. 8. _Special Marks or Deformities._ Scars, tattoo-marks, excess or defects of limbs, marks of disease, as ulcers, etc., should all be accurately noted. 9. _Injuries or Wounds_, which appear to have been the cause of death, should be carefully described. In the case of wounds, their position and direction with reference to the neighboring fixed points of the body, and their exact length and breadth, must be recorded.
