Grape–shot, and even balls of larger size from field guns, occasionally lodge. The large, gaping wounds inflicted by such missiles usually render the detection of their lodgment and position very easy; but still remarkable instances have occurred where the presence of bodies of this nature of very large size has been overlooked. Mr. Guthrie’s experience of the war in the Peninsula led him to record that “it was by no means uncommon for such missiles as a grape–shot to lodge wholly unknown to the patient, and to be discovered by the surgeon at a subsequent period, when much time had been lost and misery endured.” The same distinguished surgeon mentions a case where a ball weighing eight pounds was not discovered till the operation of amputating the thigh in which it had lodged was being performed. Baron Larrey describes a similar case: An artilleryman had his femur fractured by a ball, which, according to the man’s description, had afterward struck another artilleryman by his side. On being brought to hospital, no one doubted that the ball, after fracturing the limb, had glanced off; but on amputating, the ball, weighing five pounds, was found in the hollow of the thigh toward the groin. The wound of entrance was on the outside of the thigh; and the ball had not only fractured, but had turned round, the bone. M. Armand, surgeon attached to the French Imperial Guard, has related the case of a soldier who was brought to the ambulance, after the taking of the Mamelon Vert, in the Crimea, with his left thigh wounded; one opening, such as might be made by a large musket–ball, was found on the outside of the thigh. There was no second opening. On examination, a swelling was detected in the popliteal space, without any external mark of injury nor much pain on pressure. It was concluded to be the ball; and, on incising, an enormous grape–shot was found. It had turned round the femur without breaking it. M. Armand writes that the appearance of the wound alone would have led to the supposition that the ball had not lodged, and no one would have suspected that such a thing as a grape–shot had been the cause of it. In the British Surgical History of the Crimean War the case of a soldier of the 1st Royals, who was wounded in the face by a grape–shot weighing 1 lb. 2 oz. is recorded. The ball lodged at the back of the pharynx, and escaped observation for three weeks. Were it not for experience of many such instances, it would be deemed almost impossible that foreign substances of such size and weight could remain in the body without the knowledge of the patient, if not discovered by the surgeon. Even with so large a missile as a grape–shot, a surgeon should not be contented with examining merely by the wound, wide as it usually is, in case lodgment is suspected; it may travel in a direction which may cause its discovery to be very difficult by that track. An officer of the 19th Regiment was struck during the assault on the
