Modern surgery, general and operative . nd bullet. Hence, it is more liable to penetrate andless likely to deflect and to lodge. The tissues in the track of this bullet are lessdevitalized than in the track of the round bullet. The cutaneous surface is notso much contused. The wound of entrance is about the size of the bullet, and ispunched out or inverted; and the wound of exit is larger than that of entranceand is often everted. The bones are more seriously comminuted than by theroimd bullet, and osseous fragments may be driven widely into the tissues. Infact, an explosive effect may occur at close range. Delorme lays it down asa rule that comminution of bone makes the wound of exit larger; and heasserts that a wound of exit larger in diameter than the thimib means com-minution of bone. Gunshot-wounds Seen in Civil Life.—Wounds are occasionally inflicted by thesporting rifle or the shotgun, and frequently by blank cartridges; but the vastmajority of such woimds seen by the civilian surgeon are inflicted by the Fig. 120.—Lodged shot. Wounds from the Sporting Rifle.—In the sporting rifle a large charge ofpowder is employed. Some sporting rifle bullets have no hard jackets. Othershave an incomplete hard jacket. In a bullet with a partial hard jacket thenose of the bullet is exposed and soft. The buUets are usually larger thanthose used in the military rifle. Such bullets deform in the tissues, and inflictdreadful, tearing wounds. If a bullet of a sporting rifle strikes a Hmb, ampu-tation may be reqmred. If it strikes the head or trunk, it will almost certainlyproduce a fatal wound. Wounds from the Shotgun.—The degree of injury is in direct relation to theadjacency of the wounded individual to the gun, when the discharge takesplace, to the size and number of the shot, and to the charge of powder. Singleshot may bruise the surface and fail to enter the tissues or may enter the tissues. Gunshot-wounds 277 When many shot enter together they strike as a
