K 146 WOUNDS IN WAR A bullet travelling at a medium rate, and merely grazingthe head of the humerus, above the anatomical neck, willprobably only cut a groove through the cartilage and can-cellous structure oj the head of the bone, causing little orno fragmentation or Assuring, and the fissures which mayoccur will probably stop at the anatomical neck. If thepoint of impact be at the anatomical neck, the head of thehumerus, above this line, is usually quite separated from theshaft, and it may be broken into two or three pieces, whilefissures may extend into th
