Blood marking starts from the outer border and dries to the center of blood. At this time, skeletoni zation s tain is formed when external force is applied. The experiment was carried out at a temperature of 20 ·c and a humidity of 55 %, and a skeletonization stain was formed with a blood volume of 24 11m and a height of 76 em and a force of about 12 N. The mean diameters were 12.12 mm, and the thicknesses were 3.80 mm. The drying in 10 minutes showed significant differences. When the ratio of the thickness and the diameter of the outline blood formed between I 0 minutes and 80 minutes is represented by the time equation, the error rate was from 0.5 % to 4.25 %. Therefore, when a person drops from the tip of a f inger or a knife in a standing position to produce a contour (about 76 em in height), the result of this experiment can be used to calculate the falling blood before the contour. It is expected that it will be able to judge the generation time.
