Swain mentions a patient who stood before a looking glass, and, turning his head far around to the left, fired a pistol shot into his brain behind the right ear. The bullet passed into his mouth, and he spat it out. Some bleeding occurred from both the internal and external wounds; the man soon began to suffer with a troublesome cough, with bloody expectoration; his tongue was coated and drawn to the right; he became slightly deaf in his right ear and dragged his left leg in walking. These symptoms, together with those of congestion of the lung, continued for about a week, when he died, apparently from his pulmonary trouble.

Ford quotes the case of a lad of fifteen who was shot in the head, 3/4 inch anterior to the summit of the right ear, the ball escaping through the left os frontis, 1 1/4 inch above the center of the brow. Recovery ensued, with a cicatrix on the forehead, through which the pulsations of the brain could be distinctly seen. The senses were not at all deteriorated.

Richardson tells of a soldier who was struck by a Minie ball on the left temporal bone; the missile passed out through the left frontal bone 1/2 inch to the left of the middle of the forehead. He was only stunned, and twenty- four hours later his intellect was undisturbed. There was no operation; free suppuration with discharges of fragments of skull and broken-down substance ensued for four weeks, when the wounds closed kindly, and recovery followed.

Angle records the case of a cowboy who was shot by a comrade in mistake. The ball entered the skull beneath the left mastoid process and passed out of the right eye. The man recovered.

Rice describes the case of a boy of fourteen who was shot in the head, the ball directly traversing the brain substance, some of which protruded from the wound. The boy recovered. The ball entered one inch above and in front of the right ear and made its exit through the lambdoidal suture posteriorly.

Hall of Denver, Col., in an interesting study of gunshot wounds of the brain, writes as follows: -

"It is in regard to injuries involving the brain that the question of the production of immediate unconsciousness assumes the greatest interest. We may state broadly that if the medulla or the great centers at the base of the brain are wounded by a bullet, instant unconsciousness must result; with any other wounds involving the brain-substance it will, with very great probability, result. But there is a very broad area of uncertainty. Many instances have been recorded in which the entrance of a small bullet into the anterior part of the brain has not prevented the firing of a second shot on the part of the suicide. Personally, I have not observed such a case, however. But, aside from the injuries by the smallest missiles in the anterior parts of the brain, we may speak with almost absolute certainty with regard to the production of unconsciousness, for the jar to the brain from the blow of the bullet upon the skull would produce such a result even if the damage to the brain were not sufficient to do so.

"Many injuries to the brain from bullets of moderate size and low velocity do not cause more than a temporary loss of consciousness, and the subjects are seen by the surgeon, after the lapse of half an hour or more, apparently sound of mind. These are the cases in which the ball has lost its momentum in passing through the skull, and has consequently done little damage to the brain-substance, excepting to make a passage for itself for a short distance into the brain. It is apparently well established that, in the case of the rifle-bullet of high velocity, and especially if fired from the modern military weapons using nitro-powders, and giving an enormous initial velocity to the bullet, the transmission of the force from the displaced particles of brain (and this rule applies to any other of the soft organs as well) to the adjacent parts is such as to disorganize much of the tissue surrounding the original track of the missile. Under these circumstances a much slighter wound would be necessary to produce unconsciousness or death than in the case of a bullet of low velocity, especially if it were light in weight. Thus I have recorded elsewhere an instance of instant death in a grizzly bear, an animal certainly as tenacious of life as any we have, from a mere furrow, less than a quarter of an inch in depth, through the cortex of the brain, without injury of the skull excepting the removal of the bone necessary for the production of this furrow. The jar to the brain from a bullet of great velocity, as in this case, was alone sufficient to injure the organ irreparably. In a similar manner I have known a deer to be killed by the impact of a heavy rifle-ball against one horn, although there was no evidence of fracture of the skull. On the other hand, game animals often escape after such injuries not directly involving the brain, although temporarily rendered unconscious, as I have observed in several instances, the diagnosis undoubtedly being concussion of the brain.

"Slight injury to the brain, and especially if it be unilateral, then, may not produce unconsciousness. It is not very uncommon for a missile from a heavy weapon to strike the skull, and be deflected without the production of such a state. Near the town in which I formerly practiced, the town-marshal shot at a negro, who resisted arrest, at a distance of only a few feet, with a 44- caliber revolver, striking the culprit on the side of the head. The wound showed that the ball struck the skull and plowed along under the scalp for several inches before emerging, but it did not even knock the negro down, and no unconsciousness followed later. I once examined an express-messenger who had been shot in the occipital region by a weapon of similar size, while seated at his desk in the car. The blow was a very glancing one and did not produce unconsciousness, and probably, as in the case of the negro, because it did not strike with sufficient directness."
