(2.) “Wounds inflicted on the bone leave a red mark and a slight appearance of saturation, and where the bone is broken there will be at each end a halo-like trace of blood. Take a bone on which there are marks of a wound, and hold it up to the light; if these are of a fresh-looking red, the wound was inflicted before death and penetrated to the bone; but if there is no trace of saturation from blood, although there is a wound, it was inflicted after death.” (3.) “The bones of parents may be identified by their children in the following manner. Let the experimenter cut himself or herself with a knife, and cause the blood to drip on to the bones; then if the relationship is an actual fact, the blood will sink into the bone, otherwise it will not. _N.B._--Should the bones have been washed with salt water, even though the relationship exists, yet the blood will not soak in. This is a trick to be guarded against beforehand. “It is also said that if parent and child, or husband and wife, each cut themselves and let the blood drip into a basin of water, the two bloods will mix, whereas that of two people not thus related will not mix. “Where two brothers, who may have been separated since childhood, are desirous of establishing their identity as such, but are unable to do so by ordinary means, bid each one cut himself and let the blood drip into a basin. If they are really brothers, the two bloods will coagulate into one; otherwise not. But because fresh blood will always coagulate with the aid of a little salt or vinegar, people often smear the basin over with these to attain their own ends and deceive others; therefore always wash out the basin you are going to use, or buy a new one from a shop. Thus the trick will be defeated.” (4.) “There are some atrocious villains who, when they have murdered any one, burn the body and throw the ashes away, so that there are no bones to examine. In such cases you must carefully find out at what time the murder was committed, and where the body was burnt. Then, when you know the place, all witnesses agreeing on this point, you may proceed without further delay to examine the wounds. The mode of procedure is this. Put up your shed near where the body was burnt, and make the accused and witnesses point out themselves the exact spot. Then cut down the grass and weeds growing on this spot, and burn large quantities of fuel till the place is extremely hot, throwing on several pecks of hemp-seed. By and by brush the place clean; then, if the body was actually burnt on this spot, the oil from the seed will be found to have sunk into the ground in the form of a human figure, and wherever there were wounds on the dead man, there on this figure the oil will be found to have collected together, large or small, square, round, long, short, oblique, or straight, exactly as they were inflicted. The parts where there were no wounds will be free from any such appearances.” BOOK THE SIXTH
