Fig. 91 is inserted to illustrate the multifarious nature of the fragments into which the component parts of shells may break up. The pieces are for the most part of brass, and formed parts of either time or percussion fuses.
Fig. 92 represents the one-pound Vickers-Maxim shell in its actual size. The wounds produced by this shell are of some interest, since the Vickers-Maxim may be said to have been on trial during this campaign. The general opinion seems to have been to the effect that the moral influence produced by the continuous rapid firing of the gun and the attendant unpleasant noise were its chief virtues. A considerable number of wounds must, however, have been produced by it, which, if not of great magnitude and severity, were, at any rate, calculated to put the recipients out of action, and these wounds, moreover, were slower in healing than many of the rifle-bullet injuries.
The shell is so small that it was said to occasionally strike the body as a whole, and perforate. I was shown a case in which a wounded officer was confident that an entire shell had perforated his arm. The entry wound was at the outer part of the front of the forearm, the exit at the inner aspect of the arm, just above the elbow. Two ragged contused wounds existed, which healed slowly, but no serious nervous or vascular injury had been produced. Although it is probable that only a fragment perforated in this case, it is of interest in connection with the following.
In a case shown to me by Sir William Thomson in the Irish Hospital at Bloemfontein, an entire shell had passed between the left arm and body of a trooper, perforating the haversack, as also a non-commissioned officer's notebook contained within it, without exploding. The only injury sustained by the trooper was a contusion on the inner aspect of the elbow-joint, with slight signs of contusion of the ulnar nerve. The case is of some importance, as showing that a comparatively resistent body can be perforated without necessary explosion on the part of the shell; hence the possibility of a similar perforation of the soft parts of the body.

Fig. 93 is of a number of fragments of Vickers-Maxim shells, and it was by such that the great majority of the wounds were produced.
Wounds from fragments of these shells were, indeed, not at all rare. They were met with on any position; but, as far as my experience went, they were more common on the lower extremities than in other parts of the body, if the sufferers were in the erect position when wounded. I saw a good many wounds in the neighbourhood of the knee, some of which implicated the joint. When the injuries were received by patients in the lying or crouching positions, any part of the body was equally likely to be affected, or, again, the presence of large stones or rocks in the vicinity might determine the scattering of the flying fragments at a more dangerous height than when the shells burst from contact with the actual ground.
The relation of one or two examples of wounds from pom-pom fragments may not be without interest, the more so as they illustrate the favourable influence of a low degree of velocity on the part of a projectile. I saw three wounds produced by the percussion fuses of these shells, an experience which shows that they were not very uncommon.
