The deformity found in fig. 32 I met with both in retained bullets and also in those which had been fired into sand or anthills. The particular specimen figured was removed from the thigh of a patient wounded at the battle of Belmont. An irregular entry wound was situated over the internal tuberosity of the tibia, while a large fluctuating haematoma existed in the lower third of the thigh, at the upper part of which a hard elongated body was palpable. As was so often the case with internal haemorrhages, the patient's temperature rose high, and on the third day the haematoma was incised by Major Coutts, R.A.M.C. The core of the bullet was then found in the blood cavity near the surface, but on introduction of the finger a second body was discovered entangled in the quadriceps muscle, and this proved to be the tattered mantle. I saw similar deformity produced within the body by a bullet, which, entering by a small type aperture in the left ala of the nose, struck the margin of the right malar bone, and lodged beneath the latter. The similarity of this bullet to that seen in the ricochet in fig. 32 was exact. The form is of great importance both on account of the degree of laceration it effects in the track, the presence of two foreign bodies in the wound, and from the fact that it can be produced by making the bullet travel through sand or antheaps, since both the former in the shape of sandbags and the latter in their natural state so often formed the cover to men during the campaign. Bullets of 6.5 mm., such as the Krag-Joergensen, with steel envelopes apparently break up with great ease in sand. Fig. 33 shows a form not uncommon when the bullet comes into contact with the ribs. It is produced in bullets travelling at a low rate of velocity and striking by their side. I several times met with it when the bullet was retained, and also without fracture of the rib. In some variety it might occur after impact with any narrow margin of bone, and some importance attaches to the form, since it affords evidence as to the ease with which alterations in symmetry can be produced in Mauser bullets. Again its bent outline favours deviation in the further course of the bullet subsequent to impact with the bone, a result which I observed on more than one occasion. [Illustration: FIG. 33.--Grooved Mauser removed from anterior abdominal wall after crossing the ribs. I saw several such removed from the thoracic wall, and am inclined to attribute the grooving to impact with the margin of the ribs]
