nterior superior spine;
_exit_, 1-1/2 inch below and to right of umbilicus. A
well-marked swelling corresponded with division of the fibres
of the oblique muscles and of the rectus, and on palpation a
hollow corresponding with the track was felt. The abdominal
muscles were exceptionally well developed (fig. 84).

(160) Wounded at Magersfontein while lying prone. _Entry_,
irregular, oblique, and somewhat contused, over the eighth left
rib, in the anterior axillary line; _exit_, a slit wound
immediately above and to the left of the umbilicus. The bullet
struck a small circular metal looking-glass before entering,
hence the irregularity of the wound. The patient developed a
haemothorax, but no abdominal signs; the former was probably
parietal in origin, secondary to the fractured rib, and the
whole wound non-penetrating as far as the abdominal cavity was
concerned.

(161) Wounded at Magersfontein. _Entry_ (Mauser), 1-1/2 inch
external to and 1/2 inch below the left posterior superior
iliac spine; _exit_, 1 inch internal horizontally to the left
anterior superior spine.

No signs of intra-peritoneal injury were noted, but free
suppuration occurred in left loin; the ilium was tunnelled.

The same patient was wounded by a Jeffrey bullet in the hand;
the third metacarpal was pulverised, although the bullet, which
was longitudinally flanged, was retained.

(162) Wounded outside Heilbron. _Entry_, below the eighth right
costal cartilage; _exit_, below the eighth cartilage of the
left side. The wound of entry was slightly oval; that of exit
continued out as a 'flame'-like groove for 2 inches. A week
later the wound track could be palpated as an evident hard
continuous cord.

_Penetration of the intestinal area without definite evidence of
visceral injury._--This accident occurred with a sufficient degree of
frequency to obtain the greatest importance, both from the point of view
of diagnosis and prognosis, and as affecting the question of operative
interference. Amongst the cases reported below a number occurred in
which it was impossible to settle the question whether injury to the
bowel had occurred or not, and I will here shortly give what explanation
I can for the apparent escape of the intestine from serious injury.

We may first recall the general question of the esca
