In some cases, after a few days the edges ofthe wound about the scab take on the appearance of sUght superficial necrosisor infection. Wounds of entrance by bullets of large calibre and by shrapnel bullets havepractically the same appearance as those made by small bullets, except thatthey are apt to be less regularly circular in outline and radiating fissures are morecommon and longer. The entrance wounds by deformed bullets differ in size and shape accordingto the amount of deformation of the missile. Wliere deformation is marked,the wounds resemble those made by fragments of shell and may be mistakenfor them. Wounds of exit by undeformed small bullets are usually somewhat largerthan those of entrance and resemble them in shape and character. In Fig. 206.—Entrance and Exit Wounds in Both Thighs and the Scrotum. ( Surgical Experiencesin South Africa, Makins.) Small-cahbre bullet passed from right to left, showing round entrance andexit wounds, through smooth skin; sht-hke wounds through the skin; and small explosive exit, thebullet having set up on contact with the front surface of the femur. they are often so like them that it is impossible to determine from observationof the skin wounds alone which is the wound of entrance and which that ofexit. With large bullets the exit wounds are generally considerably larger thanthe corresponding wounds of entrance; are more irregular in outline and morefissured. The size of the exit wound is usually considerably increased if thebullet has passed through a bone and especially if bone fragments are driven outthrough it. With deformed bullets the exit wound is almost always large andjagged. Multiple w
