For this reason few cases are quoted beyond those coming under my own immediate observation, and in the few instances where others are made use of the source of quotation is indicated. It will be noted that my experience was almost entirely confined to bullet wounds, and in this respect it no doubt differs from that of surgeons employed in Natal, where shell injuries were more numerous. This is, however, of the less moment for my purpose as there is probably little to add regarding shell injuries to what is already known, while, on the other hand, the opportunity of observing large numbers of injuries from rifle bullets of small calibre has not previously been afforded to British surgeons. I think the general trend of the observations goes to show that the employment of bullets of small calibre is all to the advantage of the men wounded, except in so far as the increased possibilities of the range of fire may augment the number of individuals hit; also that such variations as exist between wounds inflicted by bullets of the Martini-Henry and Mauser types respectively, depend rather on the form and bulk of the projectile than on any inherent difference in the nature of the injuries. Thus in the chapter devoted to the general characters of the wounds, it will be seen that most of the older types of entry and exit aperture are produced in miniature by the small modern bullet, and that the main peculiarity of the deeper injuries is the frequent strict localisation of the direct damage to an area of no greater width than that crossed by narrow structures of importance such as arteries or nerves. It is to be regretted that I am unable to furnish any important statistical details, but incomplete numbers, such as are at my disposal, would be of little value. In view, however, of the considerable interval which must elapse before the Royal Army Medical Corps is able to arrange and publish the large material which will have accumulated, it has seemed unwise to defer publication until the completion of a report which will deal with such matters thoroughly.
