A considerable number of the Boers were armed with Martini-Henry rifles, and this was particularly the case with small bodies of men, rather than with the larger commandos fighting regular engagements. The Transvaal Government, moreover, had Martini-Henry rifles made as late as 1898. The Martini-Henry bullet was responsible for some of the worst fractures that came under my notice, but it is of interest to remark that its capability to do damage did not satisfy some of the Boers, who cut them as is shown in fig. 43. I cannot say what the effect of this manœuvre was, although it may have accounted for some of the wounds of the calf such as are mentioned below.
Some odd missiles were met with during the campaign; thus, at Ladysmith, I was told ball bicycle bearings were at one time in use amongst the Boers.
Anatomical characters of wounds of irregular type.—It will be seen from the above that in dealing with wounds of irregular type we have to consider those due to irregular impact of normal regulation bullets, to bullets deformed by contact with bone, to ricochet bullets, and lastly to bullets of the expanding type.
No further mention of those due to irregular impact is needful beyond what has already been said under the heading of wobbling, except to point out that, given a fair degree of velocity, these injuries may assume an actual explosive character, especially in the case of skull fractures. The description of extensive wounds accompanying comminuted fractures finds its most appropriate place under the heading of injuries to the bones, and will be there considered (Chapter V. p. 155).
'Explosive' exit apertures are, however, described as occasionally occurring in injuries involving the soft parts only. I saw no cases substantiating this belief, but several were described to me as having been met with in abdominal injuries, which terminated fatally at an early date.

Four Soft-nosed Bullets of small calibre shown in fig. 37. Twenty large-calibre leaden carbine and rifle bullets from cartridges found in Boer arsenals. These were not very extensively used, but specimens of most varieties were at times removed from our wounded men. It will be noted that some are of great weight, and a large proportion either cupped or flattened at the apex to increase area of impact and consequent resistance. The 'express' bullet with a copper core is included in this series. It is worth remarking that all the bullets of this nature in the Pretoria Arsenal were waxed, and that the wax retained its white colour on the lead.
I still, however, incline to the opinion that the bullet in these cases had come into contact with some bone, or was one of the larger varieties of projectile. A few cases of wound of the calf did, however, come under my observation which presented fairly typical 'explosive' characters without evidence of solution of continuity of the bones. I will shortly recount two of them. In the first the exit opening was very large and on the outer aspect of the limb in the upper third. The bullet had apparently passed between the bones. Secondary hæmorrhage from the anterior tibial artery necessitated exploration of the wound and ligature of the vessel (Mr. Carré). When the wound was thus laid open no injury to the bones could be detected, but I do not consider that it could be actually excluded. In the second case a wound traversed the calf transversely, just above the centre; the exit aperture was large and ragged. Deep suppuration occurred, and the wound had to be laid open, when a fracture of the tibia without solution of continuity was discovered. I also saw one or two wounds of the buttock in which very large exit apertures were present with small entry openings; in these again it was impossible to exclude passing contact of the bullet with a part of the pelvic wall. Unfortunately in all these cases it is impossible to obtain the bullet responsible for the injury. In this relation I append a diagrammatic illustration of a peculiar wound shown to me by Mr. Hanwell. In this case a typical small entry wound was situated at the outer margin of the left erector spinæ muscle in the loin. The bullet had taken a subcutaneous course of not more than three-quarters of an inch, while the exit opening was a long shallow wound measuring 4½ in. in length by 1½ in. width. (Fig. 44.)
