Gunshot injuries : how they are inflicted : their complications and treatment . en the boneis very resistant or the j acket is marred, the bullet may disintegrate.

In comparing skiagrams showing fracture one can estimatewholl3r or in part the amount of the remaining energy or shock effects 76 GUNSHOT WOUNDS in a given case by the amount of metal which is deposited. By thisstandard one will see at a glance the striking difference which is nearlyalways shown between a bone lesion by a full-jacketed bullet, one thatis but partially jacketed, and one that is unjacketed as in the case ofa lead bullet. Full-jacketed projectiles leave but few metallic par-ticles about the area of fracture as a rule. A partially jacketed bullet,like a metal-patch, or a bullet with nose marred purposely or other-wise, will leave numerous fragments, some of them much darker.

Those that are darker or black represent part of thelead core, while the fragments of lighter shade represent part of theenvelope. The presence of dark fragments alone indicates the resultof a lesion by an ordinary unjacketed lead bullet or a shrapnel ball,and more often the latter if the case is one from the very recent warsin which shrapnel balls are so frequently used. The following skiagrams exhibit bone lesions in cadavers whenfired into with projectiles from pistols and revolvers (see Table No. 3). CHARACTERISTIC LESIONS CAUSED BY PROJECTILES 77
