The wound was stated to have been received at a distance of from fifty to a hundred yards. I think we can scarcely assume that impact with the margin of the erector spinæ could have resulted in 'setting up' of the bullet, while an irregular tongue of skin at the point where the wound crossed the spines of the lumbar vertebræ did suggest possible bony contact. That the latter must have been of the slightest nature is evident, as no signs of concussion of the spinal cord were noted. I should rather be inclined to compare this case to one of gutter wound quoted on p. 56, and to assume that the bullet passed so closely beneath the surface as either to entirely sever the skin, or at any rate to allow it to give way on flexion of the back on movement.

On the ground of the observations made in the foregoing pages it will be gathered that the opinion I formed was against either the very free use or the great wounding power of so-called expanding bullets of small calibre. I believe that a great number of the injuries which were attributed to the employment of these missiles were produced either by ricochet regulation bullets of small calibre, or by large leaden bullets of the Martini-Henry type.
Symptoms.—I very much doubt whether the general symptoms observed as the result of wounds from bullets of small calibre differ in more than slight degree from those described when larger bullets were regularly employed. Great variation was met with, but I do not think a diminution in serious results in this direction corresponding to the comparatively limited nature of the direct injury to the organs or tissues can be affirmed. It is true that the immediate symptoms in many patients were amazingly slight, but after all, this has always been a feature of gunshot injuries on the field of battle and cannot be assigned a position of distinctive importance.
1. Psychical disturbance and shock.—Some remarkable instances of psychical disturbance were observed, and although perhaps in no way influenced by the calibre of the projectile, they seem worthy of note in this place. Thus a patient wounded over the cervical spine and who suffered later with a slight degree of spinal concussion emitted an involuntary shriek like that of a wounded hare on being struck; another (Martini wound), after receiving a wound of the chest, lost all sense of his surroundings for a considerable period, and occupied himself in attempts to write on a white stone lying near him on the veldt; then suddenly realising his position he was greatly bewildered in trying to account for his own action. A similar instance of preoccupation is probably offered by the dead man in the accompanying photograph (fig. 45), whose arms, forearms, and hands had evidently been in play until the actual moment of death. Again the influence of the psychical state on the actual occurrence of shock was often illustrated by the mental condition of the wounded after a battle; thus after the battles of Belmont and Graspan the patients came into hospital in excellent spirits, and minimised their injuries in the wish of rapidly regaining the front; while after the battle of Magersfontein the men were depressed and miserable, shock was more pronounced, and their sufferings were undoubtedly greater.
On the whole, however, shock was by no means a prominent symptom in the small-bore injuries of soft parts, and was possibly less than when larger bullets were the rule, and again it was often remarkably slight after the infliction of serious visceral injury. Still shock was observed in a considerable proportion of the patients, and its occurrence appeared to vary under very much the same conditions as obtain in civil practice. Grades of severity depended on individual idiosyncrasy, on the degree of excitement or preoccupation at the moment of injury, and to a certain degree on the range of fire at which the injury was received.
