Range about '300 yards.' The wound track took a directly antero-posterior course. Impact rectangular. The musculo-spiral nerve was completely divided. The plate affords a good example of the so-called 'butterfly' fracture. Two long doubly wedge-shaped lateral fragments, and pointed extremities to both main fragments, are shown. The fracture healed well, with the deposition of a large mass of provisional callus. The musculo-spiral nerve was united by suture some three months later.] Plate VIII. exhibits an oblique fracture of the lower part of the shaft produced by a bullet passing at a low rate of velocity. It does not widely differ from a perforation, and the illustration possesses some further interest as showing the deviation of a bullet likely to occur when a bone lies in its course. Although the velocity with which this bullet was travelling must have been very low, when the bone had been traversed the deviation in its course was slight. A few bony fragments from the compact tissue of the posterior surface of the humerus have been carried into the distal portion of the track. Fractures of the various prominences of the lower articular extremity were not uncommon, but deviated little from the types with which we are familiar in civil practice; the after results were good, both as to union and movement of the elbow. Explosive wounds of the soft parts were not infrequent in the arm, and fig. 48, p. 158, exhibits an extreme example. The humerus in respect of depth of covering, however, comes between the femur and the bones of the leg and forearm; hence such injuries were not so easily produced as in the latter segments of the limbs.
