To inject the body, the four principle arteries to be tied are the two common carotids and the two vertebrals, besides numerous veins and small vessels. If it is impossible to tie all the severed vessels plaster of paris may be used, and then by injecting either through the brachial, axillary or femoral a thorough injection may be obtained. The stub end of the carotid might also be used for injection, but would not advise it as in most cases we find that it would be hard to get especially if the head were cut off close to the shoulders. When both the head and the body have been injected, bring the two parts together by using a splint in the vertebral column, and having plastered well together sew the skin. Demi-surgery can be practiced to the fullest extent in this case, with great cosmetic effect. =The Head Crushed.=—Remove all the coagulated blood and the injured parts of the brain. Cleanse the cavity thoroughly and remould with plaster of paris. Inject the best you can through one or both of the carotid arteries, and complete the injection hypodermically. Inject the rest of the body in the regular way, through one of the carotids raised for the injection of the head. With the practice and use of demi-surgery, all the bruised and torn fragments may be blended together, and the cosmetic effect made almost perfect. =The Foot Crushed.=—Remove all the coagulated blood by washing, and place all the parts together as nearly natural as possible. Now inject any of the principle arteries used in embalming, watching carefully the flow of fluid and blood. As soon as you see a leakage stop injecting long enough to tie it up, and when all the visible leakages have been thus treated, wrap the whole of the injured part with a bandage saturated with a plaster of paris solution. After this becomes dry and set complete the injection. =The Chest Crushed.=—Open up the cavity and remove all the injured organs and tissues, which you will place in a vessel containing formaldehyde fluid. With a soft sponge remove all the coagulated blood from the cavity. Now tie up all the visible arteries and start the injection from the inside, using first the innominate to inject the right arm and the right side of the face then the left common carotid to inject the left side of the face and the left subclavian to inject the left arm. It must be remembered though that while one artery is being injected the others should be tied off lest by collateral circulation you would get leakages. The thoracic aorta might be used but it will be found more difficult because of the leakages which would occur through the intercostal arteries. These leakages would not occur nearly as much by the raising of the branches off the arch of the aorta, namely the innominate, the left common carotid and the left subclavian. Any leakage can be stopped by means of the lock forceps and then tied.
