Anomalies and Curiosities of Medicine [341]
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.
