The lower part of the body, if it is not injured, can be injected now through the abdominal aorta, but if there has been any damage done below the diaphragm, it would probably be best to further open up the cavity and inject each lower extremity through the common iliacs. Now replace all the organs and surround them with hardening compound, and sew up the cavity incisions, with great care and neatness. It would be well to practice demi-surgery here, so that you would become more proficient in the art, and thus be able to do more efficient work on the exposed parts, should the occasion ever demand it. =Gun-shot in the Abdomen.=—When death occurs it is generally due to severing or dividing of an artery or decomposition resulting from the injury done the intestines. The operator should open the body cavity, from the end of the sternum bone to the pubic bone, and cleanse the cavity of all the coagulated blood and other putrid matter. Locate and tie up the injured vessels. The injection can then be started from one of the principle arteries which will aid in locating the other injured vessels. Puncture the stomach and inject inside, so as to prevent the formation of gas, and after the body has been injected place hardening compound inside the body cavity and sew up carefully and neatly. =Burns and Scalds.=—A burn is an injury to the body produced by the application of a flame or of a substance heated above a certain temperature. A scald is an injury produced by the application of a liquid heated above a certain temperature.
